text: We consider random n×n matrices of the form (XX*+YY*)^{-1/2}YY*(XX*+YY*)^{-1/2},
where X and Y have independent entries with zero mean and variance one. These
matrices are the natural generalization of the Gaussian case, which are known
as MANOVA matrices and which have joint eigenvalue density given by the third
classical ensemble, the Jacobi ensemble. We show that, away from the spectral
edge, the eigenvalue density converges to the limiting density of the Jacobi ensemble
even on the shortest possible scales of order 1/n (up to log n factors). This
result is the analogue of the local Wigner semicircle law and the local Marchenko-Pastur
law for general MANOVA matrices.

text: 'We consider the ensemble of adjacency matrices of Erdős-Rényi random graphs,
that is, graphs on N vertices where every edge is chosen independently and with
probability p = p(N). We rescale the matrix so that its bulk eigenvalues are of
order one. We prove that, as long as pN→∞(with a speed at least logarithmic in
N), the density of eigenvalues of the Erdős-Rényi ensemble is given by the Wigner
semicircle law for spectral windows of length larger than N-1 (up to logarithmic
corrections). As a consequence, all eigenvectors are proved to be completely delocalized
in the sense that the ℓ∞-norms of the ℓ2-normalized eigenvectors are at most of
order N-1/2 with a very high probability. The estimates in this paper will be
used in the companion paper [Spectral statistics of Erdős-Rényi graphs II: Eigenvalue
spacing and the extreme eigenvalues (2011) Preprint] to prove the universality
of eigenvalue distributions both in the bulk and at the spectral edges under the
further restriction that pN »N2/3.'

text: We consider a general class of random matrices whose entries are centred random
variables, independent up to a symmetry constraint. We establish precise high-probability
bounds on the averages of arbitrary monomials in the resolvent matrix entries.
Our results generalize the previous results of Erdős et al. (Ann Probab, arXiv:1103.1919,
2013; Commun Math Phys, arXiv:1103.3869, 2013; J Combin 1(2):15-85, 2011) which
constituted a key step in the proof of the local semicircle law with optimal error
bound in mean-field random matrix models. Our bounds apply to random band matrices
and improve previous estimates from order 2 to order 4 in the cases relevant to
applications. In particular, they lead to a proof of the diffusion approximation
for the magnitude of the resolvent of random band matrices. This, in turn, implies
new delocalization bounds on the eigenvectors. The applications are presented
in a separate paper (Erdős et al., arXiv:1205.5669, 2013).

text: 'We consider several basic problems of algebraic topology, with connections
to combinatorial and geometric questions, from the point of view of computational
complexity. The extension problem asks, given topological spaces X; Y , a subspace
A ⊆ X, and a (continuous) map f : A → Y , whether f can be extended to a map X
→ Y . For computational purposes, we assume that X and Y are represented as finite
simplicial complexes, A is a subcomplex of X, and f is given as a simplicial map.
In this generality the problem is undecidable, as follows from Novikov''s result
from the 1950s on uncomputability of the fundamental group π1(Y ). We thus study
the problem under the assumption that, for some k ≥ 2, Y is (k - 1)-connected;
informally, this means that Y has \no holes up to dimension k-1" (a basic
example of such a Y is the sphere Sk). We prove that, on the one hand, this problem
is still undecidable for dimX = 2k. On the other hand, for every fixed k ≥ 2,
we obtain an algorithm that solves the extension problem in polynomial time assuming
Y (k - 1)-connected and dimX ≤ 2k - 1. For dimX ≤ 2k - 2, the algorithm also provides
a classification of all extensions up to homotopy (continuous deformation). This
relies on results of our SODA 2012 paper, and the main new ingredient is a machinery
of objects with polynomial-time homology, which is a polynomial-time analog of
objects with effective homology developed earlier by Sergeraert et al. We also
consider the computation of the higher homotopy groups πk(Y ), k ≥ 2, for a 1-connected
Y . Their computability was established by Brown in 1957; we show that πk(Y )
can be computed in polynomial time for every fixed k ≥ 2. On the other hand, Anick
proved in 1989 that computing πk(Y ) is #P-hard if k is a part of input, where
Y is a cell complex with certain rather compact encoding. We strengthen his result
to #P-hardness for Y given as a simplicial complex. '

text: In order to establish a reference for analysis of the function of auxin and
the auxin biosynthesis regulators SHORT INTERNODE/ STYLISH (SHI/STY) during Physcomitrella
patens reproductive development, we have described male (antheridial) and female
(archegonial) development in detail, including temporal and positional information
of organ initiation. This has allowed us to define discrete stages of organ morphogenesis
and to show that reproductive organ development in P. patens is highly organized
and that organ phyllotaxis differs between vegetative and reproductive development.
Using the PpSHI1 and PpSHI2 reporter and knockout lines, the auxin reporters GmGH3pro:GUS
and PpPINApro:GFP-GUS, and the auxin-conjugating transgene PpSHI2pro:IAAL, we
could show that the PpSHI genes, and by inference also auxin, play important roles
for reproductive organ development in moss. The PpSHI genes are required for the
apical opening of the reproductive organs, the final differentiation of the egg
cell, and the progression of canal cells into a cell death program. The apical
cells of the archegonium, the canal cells, and the egg cell are also sites of
auxin responsiveness and are affected by reduced levels of active auxin, suggesting
that auxin mediates PpSHI function in the reproductive organs.

text: A novel Taylor-Couette system has been constructed for investigations of transitional
as well as high Reynolds number turbulent flows in very large aspect ratios. The
flexibility of the setup enables studies of a variety of problems regarding hydrodynamic
instabilities and turbulence in rotating flows. The inner and outer cylinders
and the top and bottom endplates can be rotated independently with rotation rates
of up to 30 Hz, thereby covering five orders of magnitude in Reynolds numbers
(Re = 101-106). The radius ratio can be easily changed, the highest realized one
is η = 0.98 corresponding to an aspect ratio of 260 gap width in the vertical
and 300 in the azimuthal direction. For η < 0.98 the aspect ratio can be dynamically
changed during measurements and complete transparency in the radial direction
over the full length of the cylinders is provided by the usage of a precision
glass inner cylinder. The temperatures of both cylinders are controlled independently.
Overall this apparatus combines an unmatched variety in geometry, rotation rates,
and temperatures, which is provided by a sophisticated high-precision bearing
system. Possible applications are accurate studies of the onset of turbulence
and spatio-temporal intermittent flow patterns in very large domains, transport
processes of turbulence at high Re, the stability of Keplerian flows for different
boundary conditions, and studies of baroclinic instabilities.

text: Transition in shear flows is characterized by localized turbulent regions
embedded in the surrounding laminar flow. These so-called turbulent spots or puffs
are observed in a variety of shear flows and in certain Reynolds-number regimes,
and they are advected by the flow while keeping their characteristic length. We
show here for the case of pipe flow that this seemingly passive advection of turbulent
puffs involves continuous entrainment and relaminarization of laminar and turbulent
fluid across strongly convoluted interfaces. Surprisingly, interface areas are
almost two orders of magnitude larger than the pipe cross-section, while local
entrainment velocities are much smaller than the mean speed. Even though these
velocities were shown to be small and proportional to the Kolmogorov velocity
scale (in agreement with a prediction by Corrsin) in a flow without mean shear
before, we find that, in pipe flow, local entrainment velocities are about an
order of magnitude smaller than this scale. The Lagrangian method used to study
the dynamics of the laminar-turbulent interfaces allows accurate determination
of the leading and trailing edge speeds. However, to resolve the highly complex
interface dynamics requires much higher numerical resolutions than for ordinary
turbulent flows. This method also reveals that the volume flux across the leading
edge has the same radial dependence but the opposite sign as that across the trailing
edge, and it is this symmetry that is responsible for the puff shape remaining
constant.

text: The epistatic interactions that underlie evolutionary constraint have mainly
been studied for constant external conditions. However, environmental changes
may modulate epistasis and hence affect genetic constraints. Here we investigate
genetic constraints in the adaptive evolution of a novel regulatory function in
variable environments, using the lac repressor, LacI, as a model system. We have
systematically reconstructed mutational trajectories from wild type LacI to three
different variants that each exhibit an inverse response to the inducing ligand
IPTG, and analyzed the higher-order interactions between genetic and environmental
changes. We find epistasis to depend strongly on the environment. As a result,
mutational steps essential to inversion but inaccessible by positive selection
in one environment, become accessible in another. We present a graphical method
to analyze the observed complex higher-order interactions between multiple mutations
and environmental change, and show how the interactions can be explained by a
combination of mutational effects on allostery and thermodynamic stability. This
dependency of genetic constraint on the environment should fundamentally affect
evolutionary dynamics and affects the interpretation of phylogenetic data.

text: We study the problem of generating a test sequence that achieves maximal coverage
for a reactive system under test. We formulate the problem as a repeated game
between the tester and the system, where the system state space is partitioned
according to some coverage criterion and the objective of the tester is to maximize
the set of partitions (or coverage goals) visited during the game. We show the
complexity of the maximal coverage problem for non-deterministic systems is PSPACE-complete,
but is NP-complete for deterministic systems. For the special case of non-deterministic
systems with a re-initializing "reset" action, which represent running
a new test input on a re-initialized system, we show that the complexity is coNP-complete.
Our proof technique for reset games uses randomized testing strategies that circumvent
the exponentially large memory requirement of deterministic testing strategies.
We also discuss the memory requirement for deterministic strategies and extensions
of our results to other models, such as pushdown systems and timed systems.

text: 'In pipe, channel, and boundary layer flows turbulence first occurs intermittently
in space and time: at moderate Reynolds numbers domains of disordered turbulent
motion are separated by quiescent laminar regions. Based on direct numerical simulations
of pipe flow we argue here that the spatial intermittency has its origin in a
nearest neighbor interaction between turbulent regions. We further show that in
this regime turbulent flows are intrinsically intermittent with a well-defined
equilibrium turbulent fraction but without ever assuming a steady pattern. This
transition scenario is analogous to that found in simple models such as coupled
map lattices. The scaling observed implies that laminar intermissions of the turbulent
flow will persist to arbitrarily large Reynolds numbers.'

text: Turbulence is ubiquitous in nature, yet even for the case of ordinary Newtonian
fluids like water, our understanding of this phenomenon is limited. Many liquids
of practical importance are more complicated (e.g., blood, polymer melts, paints),
however; they exhibit elastic as well as viscous characteristics, and the relation
between stress and strain is nonlinear. We demonstrate here for a model system
of such complex fluids that at high shear rates, turbulence is not simply modified
as previously believed but is suppressed and replaced by a different type of disordered
motion, elasto-inertial turbulence. Elasto-inertial turbulence is found to occur
at much lower Reynolds numbers than Newtonian turbulence, and the dynamical properties
differ significantly. The friction scaling observed coincides with the so-called
"maximum drag reduction" asymptote, which is exhibited by a wide range
of viscoelastic fluids.

text: 'We consider the problem of deciding whether the persistent homology group
of a simplicial pair (K, L) can be realized as the homology H* (X) of some complex
X with L ⊂ X ⊂ K. We show that this problem is NP-complete even if K is embedded
in ℝ3. As a consequence, we show that it is NP-hard to simplify level and sublevel
sets of scalar functions on S3 within a given tolerance constraint. This problem
has relevance to the visualization of medical images by isosurfaces. We also show
an implication to the theory of well groups of scalar functions: not every well
group can be realized by some level set, and deciding whether a well group can
be realized is NP-hard.'

text: The basic idea of evolutionary game theory is that payoff determines reproductive
rate. Successful individuals have a higher payoff and produce more offspring.
But in evolutionary and ecological situations there is not only reproductive rate
but also carrying capacity. Individuals may differ in their exposure to density
limiting effects. Here we explore an alternative approach to evolutionary game
theory by assuming that the payoff from the game determines the carrying capacity
of individual phenotypes. Successful strategies are less affected by density limitation
(crowding) and reach higher equilibrium abundance. We demonstrate similarities
and differences between our framework and the standard replicator equation. Our
equation is defined on the positive orthant, instead of the simplex, but has the
same equilibrium points as the replicator equation. Linear stability analysis
produces the classical conditions for asymptotic stability of pure strategies,
but the stability properties of internal equilibria can differ in the two frameworks.
For example, in a two-strategy game with an internal equilibrium that is always
stable under the replicator equation, the corresponding equilibrium can be unstable
in the new framework resulting in a limit cycle.

text: 'We introduce quantatitive timed refinement metrics and quantitative timed
simulation functions, incorporating zenoness checks, for timed systems. These
functions assign positive real numbers between zero and infinity which quantify
the timing mismatches between two timed systems, amongst non-zeno runs. We quantify
timing mismatches in three ways: (1) the maximum timing mismatch that can arise,
(2) the "steady-state" maximum timing mismatches, where initial transient
timing mismatches are ignored; and (3) the (long-run) average timing mismatches
amongst two systems. These three kinds of mismatches constitute three important
types of timing differences. Our event times are the global times, measured from
the start of the system execution, not just the time durations of individual steps.
We present algorithms over timed automata for computing the three quantitative
simulation functions to within any desired degree of accuracy. In order to compute
the values of the quantitative simulation functions, we use a game theoretic formulation.
We introduce two new kinds of objectives for two player games on finite state
game graphs: (1) eventual debit-sum level objectives, and (2) average debit-sum
level objectives. We present algorithms for computing the optimal values for these
objectives for player 1, and then use these algorithms to compute the values of
the quantitative timed simulation functions. '

text: Models of neural responses to stimuli with complex spatiotemporal correlation
structure often assume that neurons are selective for only a small number of linear
projections of a potentially high-dimensional input. In this review, we explore
recent modeling approaches where the neural response depends on the quadratic
form of the input rather than on its linear projection, that is, the neuron is
sensitive to the local covariance structure of the signal preceding the spike.
To infer this quadratic dependence in the presence of arbitrary (e.g., naturalistic)
stimulus distribution, we review several inference methods, focusing in particular
on two information theory–based approaches (maximization of stimulus energy and
of noise entropy) and two likelihood-based approaches (Bayesian spike-triggered
covariance and extensions of generalized linear models). We analyze the formal
relationship between the likelihood-based and information-based approaches to
demonstrate how they lead to consistent inference. We demonstrate the practical
feasibility of these procedures by using model neurons responding to a flickering
variance stimulus.

text: Myopia, or near-sightedness, is an ocular refractive error of unfocused image
quality in front of the retinal plane. Individuals with high-grade myopia (dioptric
power greater than -6.00) are predisposed to ocular morbidities such as glaucoma,
retinal detachment, and myopic maculopathy. Nonsyndromic, high-grade myopia is
highly heritable, and to date multiple gene loci have been reported. We performed
exome sequencing in 4 individuals from an 11-member family of European descent
from the United States. Affected individuals had a mean dioptric spherical equivalent
of -22.00 sphere. A premature stop codon mutation c.157C>T (p.Gln53*) cosegregating
with disease was discovered within SCO2 that maps to chromosome 22q13.33. Subsequent
analyses identified three additional mutations in three highly myopic unrelated
individuals (c.341G>A, c.418G>A, and c.776C>T). To determine differential
gene expression in a developmental mouse model, we induced myopia by applying
a -15.00D lens over one eye. Messenger RNA levels of SCO2 were significantly downregulated
in myopic mouse retinae. Immunohistochemistry in mouse eyes confirmed SCO2 protein
localization in retina, retinal pigment epithelium, and sclera. SCO2 encodes for
a copper homeostasis protein influential in mitochondrial cytochrome c oxidase
activity. Copper deficiencies have been linked with photoreceptor loss and myopia
with increased scleral wall elasticity. Retinal thinning has been reported with
an SC02 variant. Human mutation identification with support from an induced myopic
animal provides biological insights of myopic development.

text: Identification of genes that control root system architecture in crop plants
requires innovations that enable high-throughput and accurate measurements of
root system architecture through time. We demonstrate the ability of a semiautomated
3D in vivo imaging and digital phenotyping pipeline to interrogate the quantitative
genetic basis of root system growth in a rice biparental mapping population, Bala
x Azucena. We phenotyped >1,400 3D root models and >57,000 2D images for
a suite of 25 traits that quantified the distribution, shape, extent of exploration,
and the intrinsic size of root networks at days 12, 14, and 16 of growth in a
gellan gum medium. From these data we identified 89 quantitative trait loci, some
of which correspond to those found previously in soil-grown plants, and provide
evidence for genetic tradeoffs in root growth allocations, such as between the
extent and thoroughness of exploration. We also developed a multivariate method
for generating and mapping central root architecture phenotypes and used it to
identify five major quantitative trait loci (r2 = 24-37%), two of which were not
identified by our univariate analysis. Our imaging and analytical platform provides
a means to identify genes with high potential for improving root traits and agronomic
qualities of crops.

text: Many key aspects of plant development are regulated by the polarized transport
of the phytohormone auxin. Cellular auxin efflux, the rate-limiting step in this
process, has been shown to rely on the coordinated action of PIN-formed (PIN)
and B-type ATP binding cassette (ABCB) carriers. Here, we report that polar auxin
transport in the Arabidopsis thaliana root also requires the action of a Major
Facilitator Superfamily (MFS) transporter, Zinc-Induced Facilitator-Like 1 (ZIFL1).
Sequencing, promoter-reporter, and fluorescent protein fusion experiments indicate
that the full-length ZIFL1.1 protein and a truncated splice isoform, ZIFL1.3,
localize to the tonoplast of root cells and the plasma membrane of leaf stomatal
guard cells, respectively. Using reverse genetics, we show that the ZIFL1.1 transporter
regulates various root auxin-related processes, while the ZIFL1.3 isoform mediates
drought tolerance by regulating stomatal closure. Auxin transport and immunolocalization
assays demonstrate that ZIFL1.1 indirectly modulates cellular auxin efflux during
shootward auxin transport at the root tip, likely by regulating plasma membrane
PIN2 abundance. Finally, heterologous expression in yeast revealed that ZIFL1.1
and ZIFL1.3 share H+-coupled K+ transport activity. Thus, by determining the subcellular
and tissue distribution of two isoforms, alternative splicing dictates a dual
function for the ZIFL1 transporter. We propose that this MFS carrier regulates
stomatal movements and polar auxin transport by modulating potassium and proton
fluxes in Arabidopsis cells.

text: Removal of cargos from the cell surface via endocytosis is an efficient mechanism
to regulate activities of plasma membrane (PM)-resident proteins, such as receptors
or transporters. Salicylic acid (SA) is an important plant hormone that is traditionally
associated with pathogen defense. Here, we describe an unanticipated effect of
SA on subcellular endocytic cycling of proteins. Both exogenous treatments and
endogenously enhanced SA levels repressed endocytosis of different PM proteins.
The SA effect on endocytosis did not involve transcription or known components
of the SA signaling pathway for transcriptional regulation. SA likely targets
an endocytic mechanism that involves the coat protein clathrin, because SA interfered
with the clathrin incidence at the PM and clathrin-deficient mutants were less
sensitive to the impact of SA on the auxin distribution and root bending during
the gravitropic response. By contrast, SA did not affect the ligand-induced endocytosis
of the FLAGELLIN SENSING2 (FLS2) receptor during pathogen responses. Our data
suggest that the established SA impact on transcription in plant immunity and
the nontranscriptional effect of SA on clathrin-mediated endocytosis are independent
mechanisms by which SA regulates distinct aspects of plant physiology.

text: The primary goal of restoration is to create self-sustaining ecological communities
that are resilient to periodic disturbance. Currently, little is known about how
restored communities respond to disturbance events such as fire and how this response
compares to remnant vegetation. Following the 2003 fires in south-eastern Australia
we examined the post-fire response of revegetation plantings and compared this
to remnant vegetation. Ten burnt and 10 unburnt (control) sites were assessed
for each of three types of vegetation (direct seeding revegetation, revegetation
using nursery seedlings (tubestock) and remnant woodland). Sixty sampling sites
were surveyed 6months after fire to quantify the initial survival of mid- and
overstorey plant species in each type of vegetation. Three and 5years after fire
all sites were resurveyed to assess vegetation structure, species diversity and
vigour, as well as indicators of soil function. Overall, revegetation showed high
(>60%) post-fire survival, but this varied among species depending on regeneration
strategy (obligate seeder or resprouter). The native ground cover, mid- and overstorey
in both types of plantings showed rapid recovery of vegetation structure and cover
within 3years of fire. This recovery was similar to the burnt remnant woodlands.
Non-native (exotic) ground cover initially increased after fire, but was no different
in burnt and unburnt sites 5years after fire. Fire had no effect on species richness,
but burnt direct seeding sites had reduced species diversity (Simpson's Diversity
Index) while diversity was higher in burnt remnant woodlands. Indices of soil
function in all types of vegetation had recovered to levels found in unburnt sites
5years after fire. These results indicate that even young revegetation (stands
<10years old) showed substantial recovery from disturbance by fire. This suggests
that revegetation can provide an important basis for restoring woodland communities
in the fire-prone Australian environment.
