text: We study periodic homogenization by Γ-convergence of integral functionals
with integrands W(x,ξ) having no polynomial growth and which are both not necessarily
continuous with respect to the space variable and not necessarily convex with
respect to the matrix variable. This allows to deal with homogenization of composite
hyperelastic materials consisting of two or more periodic components whose the
energy densities tend to infinity as the volume of matter tends to zero, i.e.,
W(x,ξ)=∑j∈J1Vj(x)Hj(ξ) where {Vj}j∈J is a finite family of open disjoint subsets
of RN, with |∂Vj|=0 for all j∈J and ∣∣RN∖⋃j∈JVj|=0, and, for each j∈J, Hj(ξ)→∞
as detξ→0. In fact, our results apply to integrands of type W(x,ξ)=a(x)H(ξ) when
H(ξ)→∞ as detξ→0 and a∈L∞(RN;[0,∞[) is 1-periodic and is either continuous almost
everywhere or not continuous. When a is not continuous, we obtain a density homogenization
formula which is a priori different from the classical one by Braides–Müller.
Although applications to hyperelasticity are limited due to the fact that our
framework is not consistent with the constraint of noninterpenetration of the
matter, our results can be of technical interest to analysis of homogenization
of integral functionals.

text: We investigate effects of quasiparticle poisoning in a Majorana island with
strong tunnel coupling to normal-metal leads. In addition to the main Coulomb
blockade diamonds, "shadow" diamonds appear, shifted by 1e in gate voltage,
consistent with transport through an excited (poisoned) state of the island. Comparison
to a simple model yields an estimate of parity lifetime for the strongly coupled
island (∼1 μs) and sets a bound for a weakly coupled island (>10 μs). Fluctuations
in the gate-voltage spacing of Coulomb peaks at high field, reflecting Majorana
hybridization, are enhanced by the reduced lever arm at strong coupling. When
converted from gate voltage to energy units, fluctuations are consistent with
previous measurements.

text: Eukaryotic cells are densely packed with macromolecular complexes and intertwining
organelles, continually transported and reshaped. Intriguingly, organelles avoid
clashing and entangling with each other in such limited space. Mitochondria form
extensive networks constantly remodeled by fission and fusion. Here, we show that
mitochondrial fission is triggered by mechanical forces. Mechano-stimulation of
mitochondria – via encounter with motile intracellular pathogens, via external
pressure applied by an atomic force microscope, or via cell migration across uneven
microsurfaces – results in the recruitment of the mitochondrial fission machinery,
and subsequent division. We propose that MFF, owing to affinity for narrow mitochondria,
acts as a membrane-bound force sensor to recruit the fission machinery to mechanically
strained sites. Thus, mitochondria adapt to the environment by sensing and responding
to biomechanical cues. Our findings that mechanical triggers can be coupled to
biochemical responses in membrane dynamics may explain how organelles orderly
cohabit in the crowded cytoplasm.

text: Biological membranes have a central role in mediating the organization of
membrane-curving proteins, a dynamic process that has proven to be challenging
to probe experimentally. Using atomic force microscopy, we capture the hierarchically
organized assemblies of Bin/amphiphysin/Rvs (BAR) proteins on supported lipid
membranes. Their structure reveals distinct long linear aggregates of proteins,
regularly spaced by up to 300 nm. Employing accurate free-energy calculations
from large-scale coarse-grained computer simulations, we found that the membrane
mediates the interaction among protein filaments as a combination of short- and
long-ranged interactions. The long-ranged component acts at strikingly long distances,
giving rise to a variety of micron-sized ordered patterns. This mechanism may
contribute to the long-ranged spatiotemporal control of membrane remodeling by
proteins in the cell.

text: 'Electric charges are conserved. The same would be expected to hold for magnetic
charges, yet magnetic monopoles have never been observed. It is therefore surprising
that the laws of nonequilibrium thermodynamics, combined with Maxwell’s equations,
suggest that colloidal particles heated or cooled in certain polar or paramagnetic
solvents may behave as if they carry an electric/magnetic charge. Here, we present
numerical simulations that show that the field distribution around a pair of such
heated/cooled colloidal particles agrees quantitatively with the theoretical predictions
for a pair of oppositely charged electric or magnetic monopoles. However, in other
respects, the nonequilibrium colloidal particles do not behave as monopoles: They
cannot be moved by a homogeneous applied field. The numerical evidence for the
monopole-like fields around heated/cooled colloidal particles is crucial because
the experimental and numerical determination of forces between such colloidal
particles would be complicated by the presence of other effects, such as thermophoresis.'

text: The formation of filaments from naturally occurring protein molecules is a
process at the core of a range of functional and aberrant biological phenomena,
such as the assembly of the cytoskeleton or the appearance of aggregates in Alzheimer's
disease. The macroscopic behaviour associated with such processes is remarkably
diverse, ranging from simple nucleated growth to highly cooperative processes
with a well-defined lagtime. Thus, conventionally, different molecular mechanisms
have been used to explain the self-assembly of different proteins. Here we show
that this range of behaviour can be quantitatively captured by a single unifying
Petri net that describes filamentous growth in terms of aggregate number and aggregate
mass concentrations. By considering general features associated with a particular
network connectivity, we are able to establish directly the rate-determining steps
of the overall aggregation reaction from the system's scaling behaviour. We illustrate
the power of this framework on a range of different experimental and simulated
aggregating systems. The approach is general and will be applicable to any future
extensions of the reaction network of filamentous self-assembly.

text: 'Cellular membranes exhibit a large variety of shapes, strongly coupled to
their function. Many biological processes involve dynamic reshaping of membranes,
usually mediated by proteins. This interaction works both ways: while proteins
influence the membrane shape, the membrane shape affects the interactions between
the proteins. To study these membrane-mediated interactions on closed and anisotropically
curved membranes, we use colloids adhered to ellipsoidal membrane vesicles as
a model system. We find that two particles on a closed system always attract each
other, and tend to align with the direction of largest curvature. Multiple particles
form arcs, or, at large enough numbers, a complete ring surrounding the vesicle
in its equatorial plane. The resulting vesicle shape resembles a snowman. Our
results indicate that these physical interactions on membranes with anisotropic
shapes can be exploited by cells to drive macromolecules to preferred regions
of cellular or intracellular membranes, and utilized to initiate dynamic processes
such as cell division. The same principle could be used to find the midplane of
an artificial vesicle, as a first step towards dividing it into two equal parts.'

text: We present a new proof rule for proving almost-sure termination of probabilistic
programs, including those that contain demonic non-determinism. An important question
for a probabilistic program is whether the probability mass of all its diverging
runs is zero, that is that it terminates "almost surely". Proving that can be
hard, and this paper presents a new method for doing so. It applies directly to
the program's source code, even if the program contains demonic choice. Like others,
we use variant functions (a.k.a. "super-martingales") that are real-valued and
decrease randomly on each loop iteration; but our key innovation is that the amount
as well as the probability of the decrease are parametric. We prove the soundness
of the new rule, indicate where its applicability goes beyond existing rules,
and explain its connection to classical results on denumerable (non-demonic) Markov
chains.

text: 'The superconducting state of matter enables one to observe quantum effects
on the macroscopic scale and hosts many fascinating phenomena. Topological defects
of the superconducting order parameter, such as vortices and fluxoid states in
multiply connected structures, are often the key ingredients of these phenomena.
This dissertation describes a new mode of magnetic force microscopy (Φ0-MFM) for
investigating vortex and fluxoid sates in mesoscopic superconducting (SC) structures.
The technique relies on the magneto-mechanical coupling of a MFM cantilever to
the motion of fluxons. The novelty of the technique is that a magnetic particle
attached to the cantilever is used not only to sense the state of a SC structure,
but also as a primary source of the inhomogeneous magnetic field which induces
that state. Φ0-MFM enables us to map the transitions between tip-induced states
during a scan: at the positions of the tip, where the two lowest energy states
become degenerate, small oscillations of the tip drive the transitions between
these states, which causes a significant shift in the resonant frequency and dissipation
of the cantilever. For narrow-wall aluminum rings, the mapped fluxoid transitions
form concentric contours on a scan. We show that the changes in the cantilever
resonant frequency and dissipation are well-described by a stochastic resonance
(SR) of cantilever-driven thermally activated phase slips (TAPS). The SR model
allows us to experimentally determine the rate of TAPS and compare it to the Langer-Ambegaokar-McCumber-Halperin
(LAMH) theory for TAPS in 1D superconducting structures. Further, we use the SR
model to qualitatively study the effects of a locally applied magnetic field on
the phase slip rate in rings containing constrictions. The states with multiple
vortices or winding numbers could be useful for the development of novel superconducting
devices, or the study of vortex interactions and interference effects. Using Φ0-MFM
allows us to induce, probe and control fluxoid states in thin wall structures
comprised of multiple loops. We show that Φ0-MFM images of the fluxoid transitions
allow us to identify the underlying states and to investigate their energetics
and dynamics even in complicated structures.'

text: New ways to investigate and manipulate fluxoid and vortex states of mesoscopic
superconducting structures are of great interest. The states with multiple vortices
or winding numbers could be useful for the study of vortex interactions and interference
effects, the braiding of Majorana bound states by winding vortices, and the development
of novel superconducting devices. We demonstrate a methodology based on magnetic
force microscopy that allows us to induce, probe and control fluxoid states in
thin wall structures comprised of multiple loops. By using micro-magnet as a source
of inhomogeneous magnetic field, we can efficiently explore the configuration
space of fluxoid states. Scanning over the structure reveals the energy crossing
points of the lowest laying fluxoid states. This is due the strong interaction
of cantilever with thermally activated fluxoid transitions at points of degeneracy.
We show that measured patterns of fluxoid transitions allow to identify the states,
investigate their energetics, and manipulate them. Further, we show that the dynamics
of driven fluxoid transitions can be described by stochastic resonance model,
which provides a unique way of measuring fluxoid transition rate and related energy
barrier for chosen transitions even in complicated structures

text: Recent studies have shown that a subset of nucleoporins (Nups) can detach
from the nuclear pore complex and move into the nuclear interior to regulate transcription.
One such dynamic Nup, called Nup98, has been implicated in gene activation in
healthy cells and has been shown to drive leukemogenesis when mutated in patients
with acute myeloid leukemia (AML). Here we show that in hematopoietic cells, Nup98
binds predominantly to transcription start sites to recruit the Wdr82–Set1A/COMPASS
(complex of proteins associated with Set1) complex, which is required for deposition
of the histone 3 Lys4 trimethyl (H3K4me3)-activating mark. Depletion of Nup98
or Wdr82 abolishes Set1A recruitment to chromatin and subsequently ablates H3K4me3
at adjacent promoters. Furthermore, expression of a Nup98 fusion protein implicated
in aggressive AML causes mislocalization of H3K4me3 at abnormal regions and up-regulation
of associated genes. Our findings establish a function of Nup98 in hematopoietic
gene activation and provide mechanistic insight into which Nup98 leukemic fusion
proteins promote AML.

text: Neural progenitor cells (NeuPCs) possess a unique nuclear architecture that
changes during differentiation. Nucleoporins are linked with cell-type-specific
gene regulation, coupling physical changes in nuclear structure to transcriptional
output; but, whether and how they coordinate with key fate-determining transcription
factors is unclear. Here we show that the nucleoporin Nup153 interacts with Sox2
in adult NeuPCs, where it is indispensable for their maintenance and controls
neuronal differentiation. Genome-wide analyses show that Nup153 and Sox2 bind
and co-regulate hundreds of genes. Binding of Nup153 to gene promoters or transcriptional
end sites correlates with increased or decreased gene expression, respectively,
and inhibiting Nup153 expression alters open chromatin configurations at its target
genes, disrupts genomic localization of Sox2, and promotes differentiation in
vitro and a gliogenic fate switch in vivo. Together, these findings reveal that
nuclear structural proteins may exert bimodal transcriptional effects to control
cell fate.

text: Premature aging disorders provide an opportunity to study the mechanisms that
drive aging. In Hutchinson-Gilford progeria syndrome (HGPS), a mutant form of
the nuclear scaffold protein lamin A distorts nuclei and sequesters nuclear proteins.
We sought to investigate protein homeostasis in this disease. Here, we report
a widespread increase in protein turnover in HGPS-derived cells compared to normal
cells. We determine that global protein synthesis is elevated as a consequence
of activated nucleoli and enhanced ribosome biogenesis in HGPS-derived fibroblasts.
Depleting normal lamin A or inducing mutant lamin A expression are each sufficient
to drive nucleolar expansion. We further show that nucleolar size correlates with
donor age in primary fibroblasts derived from healthy individuals and that ribosomal
RNA production increases with age, indicating that nucleolar size and activity
can serve as aging biomarkers. While limiting ribosome biogenesis extends lifespan
in several systems, we show that increased ribosome biogenesis and activity are
a hallmark of premature aging.

text: "We present spectroscopic follow-up observations of CR7 with ALMA, targeted
at constraining the infrared (IR) continuum and [C II]158 mm line-emission at
high spatial resolution matched to the HST/WFC3 imaging. CR7 is a luminous Lyα
emitting galaxy at z = 6.6 that consists of three separated UV-continuum components.
Our observations reveal several well-separated components of [C II] emission.
The two most luminous components in [C II] coincide with the brightest UV components
(A and B), blueshifted by »150 km s−1 with respect to the\r\npeak of Lyα emission.
Other [C II] components are observed close to UV clumps B and C and are blueshifted
by »300 and ≈80 km s−1 with respect to the systemic redshift. We do not detect
FIR continuum emission due to dust with a 3σ limiting luminosity LIR T L d 35
K 3.1 10 = <´ 10 ( ) . This allows us to mitigate uncertainties in the dust-corrected
SFR and derive SFRs for the three UV clumps A, B, and C of 28, 5, and 7 M yr−1.
All clumps have [C II] luminosities consistent within the scatter observed in
the local relation between SFR and L[ ] C II , implying that strong Lyα emission
does not necessarily anti-correlate with [C II] luminosity. Combining\r\nour measurements
with the literature, we show that galaxies with blue UV slopes have weaker [C
II] emission at fixed SFR, potentially due to their lower metallicities and/or
higher photoionization. Comparison with hydrodynamical simulations suggests that
CR7ʼs clumps have metallicities of 0.1 Z Z 0.2 < < . The observed ISM structure
of CR7 indicates that we are likely witnessing the build up of a central galaxy
in the early universe through complex accretion of satellites."

text: We present the CAlibrating LYMan-α with Hα (CALYMHA) pilot survey and new
results on Lyman α (Lyα) selected galaxies at z ∼ 2. We use a custom-built Lyα
narrow-band filter at the Isaac Newton Telescope, designed to provide a matched
volume coverage to the z = 2.23 Hα HiZELS survey. Here, we present the first results
for the COSMOS and UDS fields. Our survey currently reaches a 3σ line flux limit
of ∼4 × 10−17 erg s−1 cm−2, and a Lyα luminosity limit of ∼1042.3 erg s−1. We
find 188 Lyα emitters over 7.3 × 105 Mpc3, but also find significant numbers of
other line-emitting sources corresponding to He II, C III] and C IV emission lines.
These sources are important contaminants, and we carefully remove them, unlike
most previous studies. We find that the Lyα luminosity function at z = 2.23 is
very well described by a Schechter function up to LLy α ≈ 1043 erg s−1 with L∗=1042.59+0.16−0.08
erg s−1, ϕ∗=10−3.09+0.14−0.34 Mpc−3 and α = −1.75 ± 0.25. Above LLy α ≈ 1043 erg
s−1, the Lyα luminosity function becomes power-law like, driven by X-ray AGN.
We find that Lyα-selected emitters have a high escape fraction of 37 ± 7 per cent,
anticorrelated with Lyα luminosity and correlated with Lyα equivalent width. Lyα
emitters have ubiquitous large (≈40 kpc) Lyα haloes, ∼2 times larger than their
Hα extents. By directly comparing our Lyα and Hα luminosity functions, we find
that the global/overall escape fraction of Lyα photons (within a 13 kpc radius)
from the full population of star-forming galaxies is 5.1 ± 0.2 per cent at the
peak of the star formation history. An extra 3.3 ± 0.3 per cent of Lyα photons
likely still escape, but at larger radii.

text: While traditionally associated with active galactic nuclei (AGN), the properties
of the C II] (λ = 2326 Å), C III] (λ, λ = 1907, 1909 Å) and C IV (λ, λ = 1549,
1551 Å) emission lines are still uncertain as large, unbiased samples of sources
are scarce. We present the first blind, statistical study of C II], C III] and
C IV emitters at z ∼ 0.68, 1.05, 1.53, respectively, uniformly selected down to
a flux limit of ∼4 × 10−17 erg s−1 cm−1 through a narrow-band survey covering
an area of ∼1.4 deg2 over COSMOS and UDS. We detect 16 C II], 35 C III] and 17
C IV emitters, whose nature we investigate using optical colours as well as Hubble
Space Telescope (HST), X-ray, radio and far-infrared data. We find that z ∼ 0.7
C II] emitters are consistent with a mixture of blue (UV slope β = −2.0 ± 0.4)
star-forming (SF) galaxies with discy HST structure and AGN with Seyfert-like
morphologies. Bright C II] emitters have individual X-ray detections as well as
high average black hole accretion rates (BHARs) of ∼0.1 M⊙ yr−1. C III] emitters
at z ∼ 1.05 trace a general population of SF galaxies, with β = −0.8 ± 1.1, a
variety of optical morphologies, including isolated and interacting galaxies and
low BHAR (<0.02 M⊙ yr−1). Our C IV emitters at z ∼ 1.5 are consistent with young,
blue quasars (β ∼ −1.9) with point-like optical morphologies, bright X-ray counterparts
and large BHAR (0.8 M⊙ yr−1). We also find some surprising C II], C III] and
C IV emitters with rest-frame equivalent widths (EWs) that could be as large as
50–100 Å. AGN or spatial offsets between the UV continuum stellar disc and the
line-emitting regions may explain the large EW. These bright C II], C III] and
C IV emitters are ideal candidates for spectroscopic follow-up to fully unveil
their nature.

text: We study the production rate of ionizing photons of a sample of 588 Hα emitters
(HAEs) and 160 Lyman-α emitters (LAEs) at z = 2.2 in the COSMOS field in order
to assess the implied emissivity from galaxies, based on their ultraviolet (UV)
luminosity. By exploring the rest-frame Lyman Continuum (LyC) with GALEX/NUV data,
we find fesc < 2.8 (6.4) per cent through median (mean) stacking. By combining
the Hα luminosity density with intergalactic medium emissivity measurements from
absorption studies, we find a globally averaged 〈fesc〉 of 5.9+14.5−4.2 per cent
at z = 2.2 if we assume HAEs are the only source of ionizing photons. We find
similarly low values of the global 〈fesc〉 at z ≈ 3–5, also ruling out a high 〈fesc〉
at z < 5. These low escape fractions allow us to measure ξion, the number of produced
ionizing photons per unit UV luminosity, and investigate how this depends on galaxy
properties. We find a typical ξion ≈ 1024.77 ± 0.04 Hz erg−1 for HAEs and ξion
≈ 1025.14 ± 0.09 Hz erg−1 for LAEs. LAEs and low-mass HAEs at z = 2.2 show similar
values of ξion as typically assumed in the reionization era, while the typical
HAE is three times less ionizing. Due to an increasing ξion with increasing EW(Hα),
ξion likely increases with redshift. This evolution alone is fully in line with
the observed evolution of ξion between z ≈ 2 and 5, indicating a typical value
of ξion ≈ 1025.4 Hz erg−1 in the reionization era.

text: Recently, the C III] and C IV emission lines have been observed in galaxies
in the early Universe (z > 5), providing new ways to measure their redshift and
study their stellar populations and active galactic nuclei (AGN). We explore the
first blind C II], C III] and C IV survey (z ∼ 0.68, 1.05, 1.53, respectively)
presented in Stroe et al. (2017). We derive luminosity functions (LF) and study
properties of C II], C III] and C IV line emitters through comparisons to the
LFs of H α and Ly α emitters, UV selected star-forming (SF) galaxies and quasars
at similar redshifts. The C II] LF at z ∼ 0.68 is equally well described by a
Schechter or a power-law LF, characteristic of a mixture of SF and AGN activity.
The C III] LF (z ∼ 1.05) is consistent to a scaled down version of the Schechter
H α and Ly α LF at their redshift, indicating a SF origin. In stark contrast,
the C IV LF at z ∼ 1.53 is well fit by a power-law, quasar-like LF. We find that
the brightest UV sources (MUV < −22) will universally have C III] and C IV emission.
However, on average, C III] and C IV are not as abundant as H α or Ly α emitters
at the same redshift, with cosmic average ratios of ∼0.02–0.06 to H α and ∼0.01–0.1
to intrinsic Ly α. We predict that the C III] and C IV lines can only be truly
competitive in confirming high-redshift candidates when the hosts are intrinsically
bright and the effective Ly α escape fraction is below 1 per cent. While C III]
and C IV were proposed as good tracers of young, relatively low-metallicity galaxies
typical of the early Universe, we find that, at least at z ∼ 1.5, C IV is exclusively
hosted by AGN/quasars, especially at large line equivalent widths.

text: We use the hydrodynamical EAGLE simulation to study the magnitude and origin
of the scatter in the stellar mass–halo mass relation for central galaxies. We
separate cause and effect by correlating stellar masses in the baryonic simulation
with halo properties in a matched dark matter only (DMO) simulation. The scatter
in stellar mass increases with redshift and decreases with halo mass. At z = 0.1,
it declines from 0.25 dex at M200, DMO ≈ 1011 M⊙ to 0.12 dex at M200, DMO ≈ 1013
M⊙, but the trend is weak above 1012 M⊙. For M200, DMO < 1012.5 M⊙ up to 0.04
dex of the scatter is due to scatter in the halo concentration. At fixed halo
mass, a larger stellar mass corresponds to a more concentrated halo. This is likely
because higher concentrations imply earlier formation times and hence more time
for accretion and star formation, and/or because feedback is less efficient in
haloes with higher binding energies. The maximum circular velocity, Vmax, DMO,
and binding energy are therefore more fundamental properties than halo mass, meaning
that they are more accurate predictors of stellar mass, and we provide fitting
formulae for their relations with stellar mass. However, concentration alone cannot
explain the total scatter in the Mstar−M200,DMO relation, and it does not explain
the scatter in Mstar–Vmax, DMO. Halo spin, sphericity, triaxiality, substructure
and environment are also not responsible for the remaining scatter, which thus
could be due to more complex halo properties or non-linear/stochastic baryonic
effects.

text: We present a sample of ∼1000 emission-line galaxies at z = 0.4–4.7 from the
∼0.7deg2 High-z Emission-Line Survey in the Boötes field identified with a suite
of six narrow-band filters at ≈0.4–2.1 μm. These galaxies have been selected on
their Ly α (73), [O II] (285), H β/[O III] (387) or H α (362) emission line, and
have been classified with optical to near-infrared colours. A subsample of 98
sources have reliable redshifts from multiple narrow-band (e.g. [O II]–H α) detections
and/or spectroscopy. In this survey paper, we present the observations, selection
and catalogues of emitters. We measure number densities of Ly α, [O II], H β/[O III]
and H α and confirm strong luminosity evolution in star-forming galaxies from
z ∼ 0.4 to ∼5, in agreement with previous results. To demonstrate the usefulness
of dual-line emitters, we use the sample of dual [O II]–H α emitters to measure
the observed [O II]/H α ratio at z = 1.47. The observed [O II]/H α ratio increases
significantly from 0.40 ± 0.01 at z = 0.1 to 0.52 ± 0.05 at z = 1.47, which we
attribute to either decreasing dust attenuation with redshift, or due to a bias
in the (typically) fibre measurements in the local Universe that only measure
the central kpc regions. At the bright end, we find that both the H α and Ly α
number densities at z ≈ 2.2 deviate significantly from a Schechter form, following
a power law. We show that this is driven entirely by an increasing X-ray/active
galactic nucleus fraction with line luminosity, which reaches ≈100 per cent at
line luminosities L ≳ 3 × 1044 erg s−1.

text: We present spectroscopic follow-up of candidate luminous Ly α emitters (LAEs)
at z = 5.7–6.6 in the SA22 field with VLT/X-SHOOTER. We confirm two new luminous
LAEs at z = 5.676 (SR6) and z = 6.532 (VR7), and also present HST follow-up of
both sources. These sources have luminosities LLy α ≈ 3 × 1043 erg s−1, very high
rest-frame equivalent widths of EW0 ≳ 200 Å and narrow Ly α lines (200–340 km s−1).
VR7 is the most UV-luminous LAE at z > 6.5, with M1500 = −22.5, even brighter
in the UV than CR7. Besides Ly α, we do not detect any other rest-frame UV lines
in the spectra of SR6 and VR7, and argue that rest-frame UV lines are easier to
observe in bright galaxies with low Ly α equivalent widths. We confirm that Ly α
line widths increase with Ly α luminosity at z = 5.7, while there are indications
that Ly α lines of faint LAEs become broader at z = 6.6, potentially due to reionization.
We find a large spread of up to 3 dex in UV luminosity for >L⋆ LAEs, but find
that the Ly α luminosity of the brightest LAEs is strongly related to UV luminosity
at z = 6.6. Under basic assumptions, we find that several LAEs at z ≈ 6–7 have
Ly α escape fractions ≳ 100 per cent, indicating bursty star formation histories,
alternative Ly α production mechanisms, or dust attenuating Ly α emission differently
than UV emission. Finally, we present a method to compute ξion, the production
efficiency of ionizing photons, and find that LAEs at z ≈ 6–7 have high values
of log10(ξion/Hz erg−1) ≈ 25.51 ± 0.09 that may alleviate the need for high Lyman-Continuum
escape fractions required for reionization.

text: We present dynamical measurements from the KMOS (K-band multi-object spectrograph)
Deep Survey (KDS), which comprises 77 typical star-forming galaxies at z ≃ 3.5
in the mass range 9.0 < log (M⋆/M⊙) < 10.5. These measurements constrain the internal
dynamics, the intrinsic velocity dispersions (σint) and rotation velocities (VC)
of galaxies in the high-redshift Universe. The mean velocity dispersion of the
galaxies in our sample is σint=70.8+3.3−3.1kms−1, revealing that the increasing
average σint with increasing redshift, reported for z ≲ 2, continues out to z
≃ 3.5. Only 36 ± 8 per cent of our galaxies are rotation-dominated (VC/σint >
1), with the sample average VC/σint value much smaller than at lower redshift.
After carefully selecting comparable star-forming samples at multiple epochs,
we find that the rotation-dominated fraction evolves with redshift with a z−0.2
dependence. The rotation-dominated KDS galaxies show no clear offset from the
local rotation velocity–stellar mass (i.e. VC–M⋆) relation, although a smaller
fraction of the galaxies are on the relation due to the increase in the dispersion-dominated
fraction. These observations are consistent with a simple equilibrium model picture,
in which random motions are boosted in high-redshift galaxies by a combination
of the increasing gas fractions, accretion efficiency, specific star formation
rate and stellar feedback and which may provide significant pressure support against
gravity on the galactic disc scale.

text: Our understanding of stars through asteroseismic data analysis is limited
by our ability to take advantage of the huge amount of observed stars provided
by space missions such as CoRoT, Kepler , K2, and soon TESS and PLATO. Global
seismic pipelines provide global stellar parameters such as mass and radius using
the mean seismic parameters, as well as the effective temperature. These pipelines
are commonly used automatically on thousands of stars observed by K2 for 3 months
(and soon TESS for at least ∼ 1 month). However, pipelines are not immune from
misidentifying noise peaks and stellar oscillations. Therefore, new validation
techniques are required to assess the quality of these results. We present a new
metric called FliPer (Flicker in Power), which takes into account the average
variability at all measured time scales. The proper calibration of FliPer enables
us to obtain good estimations of global stellar parameters such as surface gravity
that are robust against the influence of noise peaks and hence are an excellent
way to find faults in asteroseismic pipelines.

text: Diffusions and related random walk procedures are of central importance in
many areas of machine learning, data analysis, and applied mathematics. Because
they spread mass agnostically at each step in an iterative manner, they can sometimes
spread mass “too aggressively,” thereby failing to find the “right” clusters.
We introduce a novel Capacity Releasing Diffusion (CRD) Process, which is both
faster and stays more local than the classical spectral diffusion process. As
an application, we use our CRD Process to develop an improved local algorithm
for graph clustering. Our local graph clustering method can find local clusters
in a model of clustering where one begins the CRD Process in a cluster whose vertices
are connected better internally than externally by an O(log2n) factor, where n
is the number of nodes in the cluster. Thus, our CRD Process is the first local
graph clustering algorithm that is not subject to the well-known quadratic Cheeger
barrier. Our result requires a certain smoothness condition, which we expect to
be an artifact of our analysis. Our empirical evaluation demonstrates improved
results, in particular for realistic social graphs where there are moderately
good—but not very good—clusters.

text: "We study the problem of maintaining a breadth-first spanning tree (BFS tree)
in partially dynamic distributed networks modeling a sequence of either failures
or additions of communication links (but not both). We present deterministic (1+ϵ)-approximation
algorithms whose amortized time (over some number of link changes) is sublinear
in D, the maximum diameter of the network.\r\n\r\nOur technique also leads to
a deterministic (1+ϵ)-approximate incremental algorithm for single-source shortest
paths in the sequential (usual RAM) model. Prior to our work, the state of the
art was the classic exact algorithm of Even and Shiloach (1981), which is optimal
under some assumptions (Roditty and Zwick 2011; Henzinger et al. 2015). Our result
is the first to show that, in the incremental setting, this bound can be beaten
in certain cases if some approximation is allowed."

text: We study the problem of maximizing a monotone submodular function with viability
constraints. This problem originates from computational biology, where we are
given a phylogenetic tree over a set of species and a directed graph, the so-called
food web, encoding viability constraints between these species. These food webs
usually have constant depth. The goal is to select a subset of k species that
satisfies the viability constraints and has maximal phylogenetic diversity. As
this problem is known to be NP-hard, we investigate approximation algorithms.
We present the first constant factor approximation algorithm if the depth is constant.
Its approximation ratio is (1−1e√). This algorithm not only applies to phylogenetic
trees with viability constraints but for arbitrary monotone submodular set functions
with viability constraints. Second, we show that there is no (1−1/e+ϵ)-approximation
algorithm for our problem setting (even for additive functions) and that there
is no approximation algorithm for a slight extension of this setting.

text: We study space complexity and time-space trade-offs with a focus not on peak
memory usage but on overall memory consumption throughout the computation. Such
a cumulative space measure was introduced for the computational model of parallel
black pebbling by [Alwen and Serbinenko ’15] as a tool for obtaining results in
cryptography. We consider instead the non- deterministic black-white pebble game
and prove optimal cumulative space lower bounds and trade-offs, where in order
to minimize pebbling time the space has to remain large during a significant fraction
of the pebbling. We also initiate the study of cumulative space in proof complexity,
an area where other space complexity measures have been extensively studied during
the last 10–15 years. Using and extending the connection between proof complexity
and pebble games in [Ben-Sasson and Nordström ’08, ’11] we obtain several strong
cumulative space results for (even parallel versions of) the resolution proof
system, and outline some possible future directions of study of this, in our opinion,
natural and interesting space measure.

text: "In recent years it has become popular to study dynamic problems in a sensitivity
setting: Instead of allowing for an arbitrary sequence of updates, the sensitivity
model only allows to apply batch updates of small size to the original input data.
The sensitivity model is particularly appealing since recent strong conditional
lower bounds ruled out fast algorithms for many dynamic problems, such as shortest
paths, reachability, or subgraph connectivity.\r\n\r\nIn this paper we prove conditional
lower bounds for these and additional problems in a sensitivity setting. For example,
we show that under the Boolean Matrix Multiplication (BMM) conjecture combinatorial
algorithms cannot compute the (4/3-\\varepsilon)-approximate diameter of an undirected
unweighted dense graph with truly subcubic preprocessing time and truly subquadratic
update/query time. This result is surprising since in the static setting it is
not clear whether a reduction from BMM to diameter is possible. We further show
under the BMM conjecture that many problems, such as reachability or approximate
shortest paths, cannot be solved faster than by recomputation from scratch even
after only one or two edge insertions. We extend our reduction from BMM to Diameter
to give a reduction from All Pairs Shortest Paths to Diameter under one deletion
in weighted graphs. This is intriguing, as in the static setting it is a big open
problem whether Diameter is as hard as APSP. We further get a nearly tight lower
bound for shortest paths after two edge deletions based on the APSP conjecture.
We give more lower bounds under the Strong Exponential Time Hypothesis. Many of
our lower bounds also hold for static oracle data structures where no sensitivity
is required.\r\n\r\nFinally, we give the first algorithm for the (1+\\varepsilon)-approximate
radius, diameter, and eccentricity problems in directed or undirected unweighted
graphs in case of single edges failures. The algorithm has a truly subcubic running
time for graphs with a truly subquadratic number of edges; it is tight w.r.t.
the conditional lower bounds we obtain."

text: "We introduce a new algorithmic framework for designing dynamic graph algorithms
in minor-free graphs, by exploiting the structure of such graphs and a tool called
vertex sparsification, which is a way to compress large graphs into small ones
that well preserve relevant properties among a subset of vertices and has previously
mainly been used in the design of approximation algorithms.\r\n\r\nUsing this
framework, we obtain a Monte Carlo randomized fully dynamic algorithm for (1 +
epsilon)-approximating the energy of electrical flows in n-vertex planar graphs
with tilde{O}(r epsilon^{-2}) worst-case update time and tilde{O}((r + n / sqrt{r})
epsilon^{-2}) worst-case query time, for any r larger than some constant. For
r=n^{2/3}, this gives tilde{O}(n^{2/3} epsilon^{-2}) update time and tilde{O}(n^{2/3}
epsilon^{-2}) query time. We also extend this algorithm to work for minor-free
graphs with similar approximation and running time guarantees. Furthermore, we
illustrate our framework on the all-pairs max flow and shortest path problems
by giving corresponding dynamic algorithms in minor-free graphs with both sublinear
update and query times. To the best of our knowledge, our results are the first
to systematically establish such a connection between dynamic graph algorithms
and vertex sparsification.\r\n\r\nWe also present both upper bound and lower bound
for maintaining the energy of electrical flows in the incremental subgraph model,
where updates consist of only vertex activations, which might be of independent
interest."

text: "We consider the problem of maintaining an approximately maximum (fractional)
matching and an approximately minimum vertex cover in a dynamic graph. Starting
with the seminal paper by Onak and Rubinfeld [STOC 2010], this problem has received
significant attention in recent years. There remains, however, a polynomial gap
between the best known worst case update time and the best known amortised update
time for this problem, even after allowing for randomisation. Specifically, Bernstein
and Stein [ICALP 2015, SODA 2016] have the best known worst case update time.
They present a deterministic data structure with approximation ratio (3/2 + ∊)
and worst case update time O(m1/4/ ∊2), where m is the number of edges in the
graph. In recent past, Gupta and Peng [FOCS 2013] gave a deterministic data structure
with approximation ratio (1+ ∊) and worst case update time No known randomised
data structure beats the worst case update times of these two results. In contrast,
the paper by Onak and Rubinfeld [STOC 2010] gave a randomised data structure with
approximation ratio O(1) and amortised update time O(log2 n), where n is the number
of nodes in the graph. This was later improved by Baswana, Gupta and Sen [FOCS
2011] and Solomon [FOCS 2016], leading to a randomised date structure with approximation
ratio 2 and amortised update time O(1).\r\n\r\nWe bridge the polynomial gap between
the worst case and amortised update times for this problem, without using any
randomisation. We present a deterministic data structure with approximation ratio
(2 + ∊) and worst case update time O(log3 n), for all sufficiently small constants
∊."

text: "We study the problem of computing a minimum cut in a simple, undirected graph
and give a deterministic O(m log2 n log log2 n) time algorithm. This improves
both on the best previously known deterministic running time of O(m log12 n) (Kawarabayashi
and Thorup [12]) and the best previously known randomized running time of O(mlog3n)
(Karger [11]) for this problem, though Karger's algorithm can be further applied
to weighted graphs.\r\n\r\nOur approach is using the Kawarabayashi and Tho- rup
graph compression technique, which repeatedly finds low-conductance cuts. To find
these cuts they use a diffusion-based local algorithm. We use instead a flow-
based local algorithm and suitably adjust their framework to work with our flow-based
subroutine. Both flow and diffusion based methods have a long history of being
applied to finding low conductance cuts. Diffusion algorithms have several variants
that are naturally local while it is more complicated to make flow methods local.
Some prior work has proven nice properties for local flow based algorithms with
respect to improving or cleaning up low conductance cuts. Our flow subroutine,
however, is the first that is both local and produces low conductance cuts. Thus,
it may be of independent interest."

text: "Graph Sparsification aims at compressing large graphs into smaller ones while
(approximately) preserving important characteristics of the input graph. In this
work we study Vertex Sparsifiers, i.e., sparsifiers whose goal is to reduce the
number of vertices. Given a weighted graph G=(V,E), and a terminal set K with
|K|=k, a quality-q vertex cut sparsifier of G is a graph H with K contained in
V_H that preserves the value of minimum cuts separating any bipartition of K,
up to a factor of q. We show that planar graphs with all the k terminals lying
on the same face admit quality-1 vertex cut sparsifier of size O(k^2) that are
also planar. Our result extends to vertex flow and distance sparsifiers. It improves
the previous best known bound of O(k^2 2^(2k)) for cut and flow sparsifiers by
an exponential factor, and matches an Omega(k^2) lower-bound for this class of
graphs.\r\n\r\nWe also study vertex reachability sparsifiers for directed graphs.
Given a digraph G=(V,E) and a terminal set K, a vertex reachability sparsifier
of G is a digraph H=(V_H,E_H), K contained in V_H that preserves all reachability
information among terminal pairs. We introduce the notion of reachability-preserving
minors, i.e., we require H to be a minor of G. Among others, for general planar
digraphs, we construct reachability-preserving minors of size O(k^2 log^2 k).
We complement our upper-bound by showing that there exists an infinite family
of acyclic planar digraphs such that any reachability-preserving minor must have
Omega(k^2) vertices."

text: "Online social networks allow the collection of large amounts of data about
the influence between users connected by a friendship-like relationship. When
distributing items among agents forming a social network, this information allows
us to exploit network externalities that each agent receives from his neighbors
that get the same item. In this paper we consider Friends-of-Friends (2-hop) network
externalities, i.e., externalities that not only depend on the neighbors that
get the same item but also on neighbors of neighbors. For these externalities
we study a setting where multiple different items are assigned to unit-demand
agents. Specifically, we study the problem of welfare maximization under different
types of externality functions. Let n be the number of agents and m be the number
of items. Our contributions are the following: (1) We show that welfare maximization
is APX-hard; we show that even for step functions with 2-hop (and also with 1-hop)
externalities it is NP-hard to approximate social welfare better than (1−1/e).
(2) On the positive side we present (i) an \U0001D442(\U0001D45B√)-approximation
algorithm for general concave externality functions, (ii) an O(log m)-approximation
algorithm for linear externality functions, and (iii) a 518(1−1/\U0001D452)-approximation
algorithm for 2-hop step function externalities. We also improve the result from
[7] for 1-hop step function externalities by giving a 12(1−1/\U0001D452)-approximation
algorithm."

text: Variation in genotypes may be responsible for differences in dispersal rates,
directional biases, and growth rates of individuals. These traits may favor certain
genotypes and enhance their spatiotemporal spreading into areas occupied by the
less advantageous genotypes. We study how these factors influence the speed of
spreading in the case of two competing genotypes under the assumption that spatial
variation of the total population is small compared to the spatial variation of
the frequencies of the genotypes in the population. In that case, the dynamics
of the frequency of one of the genotypes is approximately described by a generalized
Fisher–Kolmogorov–Petrovskii–Piskunov (F–KPP) equation. This generalized F–KPP
equation with (nonlinear) frequency-dependent diffusion and advection terms admits
traveling wave solutions that characterize the invasion of the dominant genotype.
Our existence results generalize the classical theory for traveling waves for
the F–KPP with constant coefficients. Moreover, in the particular case of the
quadratic (monostable) nonlinear growth–decay rate in the generalized F–KPP we
study in detail the influence of the variance in diffusion and mean displacement
rates of the two genotypes on the minimal wave propagation speed.

text: The way organic multistep synthesis is performed is changing due to the adoption
of flow chemical techniques, which has enabled the development of improved methods
to make complex molecules. The modular nature of the technique provides not only
access to target molecules via linear flow approaches but also for the targeting
of structural cores with single systems. This perspective article summarizes the
state of the art of continuous multistep synthesis and discusses the main challenges
and opportunities in this area.

text: Systems such as fluid flows in channels and pipes or the complex Ginzburg–Landau
system, defined over periodic domains, exhibit both continuous symmetries, translational
and rotational, as well as discrete symmetries under spatial reflections or complex
conjugation. The simplest, and very common symmetry of this type is the equivariance
of the defining equations under the orthogonal group O(2). We formulate a novel
symmetry reduction scheme for such systems by combining the method of slices with
invariant polynomial methods, and show how it works by applying it to the Kuramoto–Sivashinsky
system in one spatial dimension. As an example, we track a relative periodic orbit
through a sequence of bifurcations to the onset of chaos. Within the symmetry-reduced
state space we are able to compute and visualize the unstable manifolds of relative
periodic orbits, their torus bifurcations, a transition to chaos via torus breakdown,
and heteroclinic connections between various relative periodic orbits. It would
be very hard to carry through such analysis in the full state space, without a
symmetry reduction such as the one we present here.

text: The Leidenfrost effect occurs when an object near a hot surface vaporizes
rapidly enough to lift itself up and hover. Although well understood for liquids
and stiff sublimable solids, nothing is known about the effect with materials
whose stiffness lies between these extremes. Here we introduce a new phenomenon
that occurs with vaporizable soft solids - the elastic Leidenfrost effect. By
dropping hydrogel spheres onto hot surfaces we find that, rather than hovering,
they energetically bounce several times their diameter for minutes at a time.
With high-speed video during a single impact, we uncover high-frequency microscopic
gap dynamics at the sphere/substrate interface. We show how these otherwise-hidden
agitations constitute work cycles that harvest mechanical energy from the vapour
and sustain the bouncing. Our findings suggest a new strategy for injecting mechanical
energy into a widely used class of soft materials, with potential relevance to
fields such as active matter, soft robotics and microfluidics.

text: We consider the problems of maintaining approximate maximum matching and minimum
vertex cover in a dynamic graph. Starting with the seminal work of Onak and Rubinfeld
[STOC 2010], this problem has received significant attention in recent years.
Very recently, extending the framework of Baswana, Gupta and Sen [FOCS 2011],
Solomon [FOCS 2016] gave a randomized 2-approximation dynamic algorithm for this
problem that has amortized update time of O(1) with high probability. We consider
the natural open question of derandomizing this result. We present a new deterministic
fully dynamic algorithm that maintains a O(1)-approximate minimum vertex cover
and maximum fractional matching, with an amortized update time of O(1). Previously,
the best deterministic algorithm for this problem was due to Bhattacharya, Henzinger
and Italiano [SODA 2015]; it had an approximation ratio of (2+ϵ) and an amortized
update time of O(logn/ϵ2). Our result can be generalized to give a fully dynamic
O(f3)-approximation algorithm with O(f2) amortized update time for the hypergraph
vertex cover and fractional matching problems, where every hyperedge has at most
f vertices.

text: 'A drawing of a graph G is radial if the vertices of G are placed on concentric
circles C 1 , . . . , C k with common center c , and edges are drawn radially
: every edge intersects every circle centered at c at most once. G is radial planar
if it has a radial embedding, that is, a crossing-free radial drawing. If the
vertices of G are ordered or partitioned into ordered levels (as they are for
leveled graphs), we require that the assignment of vertices to circles corresponds
to the given ordering or leveling. We show that a graph G is radial planar if
G has a radial drawing in which every two edges cross an even number of times;
the radial embedding has the same leveling as the radial drawing. In other words,
we establish the weak variant of the Hanani-Tutte theorem for radial planarity.
This generalizes a result by Pach and Toth.'

text: 'We use a three-pulse ultrafast optical spectroscopy to study the relaxation
processes in a frustrated Mott insulator Na2IrO3. By being able to independently
produce the out-of-equilibrium bound states (excitons) of doublons and holons
with the first pulse and suppress the underlying antiferromagnetic order with
the second one, we were able to elucidate the relaxation mechanism of quasiparticles
in this system. By observing the difference in the exciton dynamics in the magnetically
ordered and disordered phases we found that the mass of this quasiparticle is
mostly determined by its interaction with the surrounding spins. '

text: We used femtosecond optical pump-probe spectroscopy to study the photoinduced
change in reflectivity of thin films of the electron-doped cuprate La2-xCexCuO4
(LCCO) with dopings of x=0.08 (underdoped) and x=0.11 (optimally doped). Above
Tc, we observe fluence-dependent relaxation rates that begin at a temperature
similar to the one where transport measurements first show signatures of antiferromagnetic
correlations. Upon suppressing superconductivity with a magnetic field, it is
found that the fluence and temperature dependence of relaxation rates are consistent
with bimolecular recombination of electrons and holes across a gap (2ΔAF) originating
from antiferromagnetic correlations which comprise the pseudogap in electron-doped
cuprates. This can be used to learn about coupling between electrons and high-energy
(ω>2ΔAF) excitations in these compounds and set limits on the time scales on
which antiferromagnetic correlations are static.

text: Pancreatic cancer has a five-year survival rate of ~8%, with characteristic
molecular heterogeneity and restricted treatment options. Targeting metabolism
has emerged as a potentially effective therapeutic strategy for cancers such as
pancreatic cancer, which are driven by genetic alterations that are not tractable
drug targets. Although somatic mitochondrial genome (mtDNA) mutations have been
observed in various tumors types, understanding of metabolic genotype-phenotype
relationships is limited.

text: The Loschmidt echo, defined as the overlap between quantum wave function evolved
with different Hamiltonians, quantifies the sensitivity of quantum dynamics to
perturbations and is often used as a probe of quantum chaos. In this work we consider
the behavior of the Loschmidt echo in the many-body localized phase, which is
characterized by emergent local integrals of motion and provides a generic example
of nonergodic dynamics. We demonstrate that the fluctuations of the Loschmidt
echo decay as a power law in time in the many-body localized phase, in contrast
to the exponential decay in few-body ergodic systems. We consider the spin-echo
generalization of the Loschmidt echo and argue that the corresponding correlation
function saturates to a finite value in localized systems. Slow, power-law decay
of fluctuations of such spin-echo-type overlap is related to the operator spreading
and is present only in the many-body localized phase, but not in a noninteracting
Anderson insulator. While most of the previously considered probes of dephasing
dynamics could be understood by approximating physical spin operators with local
integrals of motion, the Loschmidt echo and its generalizations crucially depend
on the full expansion of the physical operators via local integrals of motion
operators, as well as operators which flip local integrals of motion. Hence these
probes allow one to get insights into the relation between physical operators
and local integrals of motion and access the operator spreading in the many-body
localized phase.

text: Most kinesin motors move in only one direction along microtubules. Members
of the kinesin-5 subfamily were initially described as unidirectional plus-end-directed
motors and shown to produce piconewton forces. However, some fungal kinesin-5
motors are bidirectional. The force production of a bidirectional kinesin-5 has
not yet been measured. Therefore, it remains unknown whether the mechanism of
the unconventional minus-end-directed motility differs fundamentally from that
of plus-end-directed stepping. Using force spectroscopy, we have measured here
the forces that ensembles of purified budding yeast kinesin-5 Cin8 produce in
microtubule gliding assays in both plus- and minus-end direction. Correlation
analysis of pause forces demonstrated that individual Cin8 molecules produce additive
forces in both directions of movement. In ensembles, Cin8 motors were able to
produce single-motor forces up to a magnitude of ∼1.5 pN. Hence, these properties
appear to be conserved within the kinesin-5 subfamily. Force production was largely
independent of the directionality of movement, indicating similarities between
the motility mechanisms for both directions. These results provide constraints
for the development of models for the bidirectional motility mechanism of fission
yeast kinesin-5 and provide insight into the function of this mitotic motor.

text: The computation of the winning set for parity objectives and for Streett objectives
in graphs as well as in game graphs are central problems in computer-aided verification,
with application to the verification of closed systems with strong fairness conditions,
the verification of open systems, checking interface compatibility, well-formedness
of specifications, and the synthesis of reactive systems. We show how to compute
the winning set on n vertices for (1) parity-3 (aka one-pair Streett) objectives
in game graphs in time O(n5/2) and for (2) k-pair Streett objectives in graphs
in time O(n2+nklogn). For both problems this gives faster algorithms for dense
graphs and represents the first improvement in asymptotic running time in 15 years.

text: This paper presents a method for simulating water surface waves as a displacement
field on a 2D domain. Our method relies on Lagrangian particles that carry packets
of water wave energy; each packet carries information about an entire group of
wave trains, as opposed to only a single wave crest. Our approach is unconditionally
stable and can simulate high resolution geometric details. This approach also
presents a straightforward interface for artistic control, because it is essentially
a particle system with intuitive parameters like wavelength and amplitude. Our
implementation parallelizes well and runs in real time for moderately challenging
scenarios.
