text: "Point sets, geometric networks, and arrangements of hyperplanes are fundamental
objects in\r\ndiscrete geometry that have captivated mathematicians for centuries,
if not millennia. This\r\nthesis seeks to cast new light on these structures by
illustrating specific instances where a\r\ntopological perspective, specifically
through discrete Morse theory and persistent homology,\r\nprovides valuable insights.\r\n\r\nAt
first glance, the topology of these geometric objects might seem uneventful: point
sets\r\nessentially lack of topology, arrangements of hyperplanes are a decomposition
of Rd, which\r\nis a contractible space, and the topology of a network primarily
involves the enumeration\r\nof connected components and cycles within the network.
However, beneath this apparent\r\nsimplicity, there lies an array of intriguing
structures, a small subset of which will be uncovered\r\nin this thesis.\r\n\r\nFocused
on three case studies, each addressing one of the mentioned objects, this work\r\nwill
showcase connections that intertwine topology with diverse fields such as combinatorial\r\ngeometry,
algorithms and data structures, and emerging applications like spatial biology.\r\n\r\n"

text: We present a dynamic data structure for maintaining the persistent homology
of a time series of real numbers. The data structure supports local operations,
including the insertion and deletion of an item and the cutting and concatenating
of lists, each in time O(log n + k), in which n counts the critical items and
k the changes in the augmented persistence diagram. To achieve this, we design
a tailor-made tree structure with an unconventional representation, referred to
as banana tree, which may be useful in its own right.

text: The brain’s functionality is developed and maintained through synaptic plasticity.
As synapses undergo plasticity, they also affect each other. The nature of such
‘co-dependency’ is difficult to disentangle experimentally, because multiple synapses
must be monitored simultaneously. To help understand the experimentally observed
phenomena, we introduce a framework that formalizes synaptic co-dependency between
different connection types. The resulting model explains how inhibition can gate
excitatory plasticity while neighboring excitatory–excitatory interactions determine
the strength of long-term potentiation. Furthermore, we show how the interplay
between excitatory and inhibitory synapses can account for the quick rise and
long-term stability of a variety of synaptic weight profiles, such as orientation
tuning and dendritic clustering of co-active synapses. In recurrent neuronal networks,
co-dependent plasticity produces rich and stable motor cortex-like dynamics with
high input sensitivity. Our results suggest an essential role for the neighborly
synaptic interaction during learning, connecting micro-level physiology with network-wide
phenomena.

text: 'We propose a novel approach to concentration for non-independent random variables.
The main idea is to “pretend” that the random variables are independent and pay
a multiplicative price measuring how far they are from actually being independent.
This price is encapsulated in the Hellinger integral between the joint and the
product of the marginals, which is then upper bounded leveraging tensorisation
properties. Our bounds represent a natural generalisation of concentration inequalities
in the presence of dependence: we recover exactly the classical bounds (McDiarmid’s
inequality) when the random variables are independent. Furthermore, in a “large
deviations” regime, we obtain the same decay in the probability as for the independent
case, even when the random variables display non-trivial dependencies. To show
this, we consider a number of applications of interest. First, we provide a bound
for Markov chains with finite state space. Then, we consider the Simple Symmetric
Random Walk, which is a non-contracting Markov chain, and a non-Markovian setting
in which the stochastic process depends on its entire past. To conclude, we propose
an application to Markov Chain Monte Carlo methods, where our approach leads to
an improved lower bound on the minimum burn-in period required to reach a certain
accuracy. In all of these settings, we provide a regime of parameters in which
our bound fares better than what the state of the art can provide.'

text: 'The James Webb Space Telescope is revealing a new population of dust-reddened
broad-line active galactic nuclei (AGN) at redshifts z ≳ 5. Here we present deep
NIRSpec/Prism spectroscopy from the Cycle 1 Treasury program Ultradeep NIRSpec
and NIRCam ObserVations before the Epoch of Reionization (UNCOVER) of 15 AGN candidates
selected to be compact, with red continua in the rest-frame optical but with blue
slopes in the UV. From NIRCam photometry alone, they could have been dominated
by dusty star formation or an AGN. Here we show that the majority of the compact
red sources in UNCOVER are dust-reddened AGN: 60% show definitive evidence for
broad-line Hα with a FWHM > 2000 km s −1, 20% of the current data are inconclusive,
and 20% are brown dwarf stars. We propose an updated photometric criterion to
select red z > 5 AGN that excludes brown dwarfs and is expected to yield >80%
AGN. Remarkably, among all zphot > 5 galaxies with F277W – F444W > 1 in UNCOVER
at least 33% are AGN regardless of compactness, climbing to at least 80% AGN for
sources with F277W – F444W > 1.6. The confirmed AGN have black hole masses of
107–109M⊙. While their UV luminosities (−16 > MUV > −20 AB mag) are low compared
to UV-selected AGN at these epochs, consistent with percent-level scattered AGN
light or low levels of unobscured star formation, the inferred bolometric luminosities
are typical of 107–109M⊙ black holes radiating at ∼10%–40% the Eddington limit.
The number densities are surprisingly high at ∼10−5 Mpc−3 mag−1, 100 times more
common than the faintest UV-selected quasars, while accounting for ∼1% of the
UV-selected galaxies. While their UV faintness suggests they may not contribute
strongly to reionization, their ubiquity poses challenges to models of black hole
growth.'

text: 'A linearly ordered (LO) k-colouring of a hypergraph is a colouring of its
vertices with colours 1, … , k such that each edge contains a unique maximal colour.
Deciding whether an input hypergraph admits LO k-colouring with a fixed number
of colours is NP-complete (and in the special case of graphs, LO colouring coincides
with the usual graph colouring). Here, we investigate the complexity of approximating
the "linearly ordered chromatic number" of a hypergraph. We prove that the following
promise problem is NP-complete: Given a 3-uniform hypergraph, distinguish between
the case that it is LO 3-colourable, and the case that it is not even LO 4-colourable.
We prove this result by a combination of algebraic, topological, and combinatorial
methods, building on and extending a topological approach for studying approximate
graph colouring introduced by Krokhin, Opršal, Wrochna, and Živný (2023).'

text: Interpretation of extracellular recordings can be challenging due to the long
range of electric field. This challenge can be mitigated by estimating the current
source density (CSD). Here we introduce kCSD-python, an open Python package implementing
Kernel Current Source Density (kCSD) method and related tools to facilitate CSD
analysis of experimental data and the interpretation of results. We show how to
counter the limitations imposed by noise and assumptions in the method itself.
kCSD-python allows CSD estimation for an arbitrary distribution of electrodes
in 1D, 2D, and 3D, assuming distributions of sources in tissue, a slice, or in
a single cell, and includes a range of diagnostic aids. We demonstrate its features
in a Jupyter Notebook tutorial which illustrates a typical analytical workflow
and main functionalities useful in validating analysis results.
acknowledgement: 'The Python implementation of kCSD was started by Grzegorz Parka
during Google Summer of Code project through the International Neuroinformatics
Coordinating Facility. Jan Mąka implemented the first Python version of skCSD class.

text: We perform a diagrammatic analysis of the energy of a mobile impurity immersed
in a strongly interacting two-component Fermi gas to second order in the impurity-bath
interaction. These corrections demonstrate divergent behavior in the limit of
large impurity momentum. We show the fundamental processes responsible for these
logarithmically divergent terms. We study the problem in the general case without
any assumptions regarding the fermion-fermion interactions in the bath. We show
that the divergent term can be summed up to all orders in the Fermi-Fermi interaction
and that the resulting expression is equivalent to the one obtained in the few-body
calculation. Finally, we provide a perturbative calculation to the second order
in the Fermi-Fermi interaction, and we show the diagrams responsible for these
terms.

text: For some k∈Z≥0∪{∞}, we call a linear forest k-bounded if each of its components
has at most k edges. We will say a (k,ℓ)-bounded linear forest decomposition of
a graph G is a partition of E(G) into the edge sets of two linear forests Fk,Fℓ
where Fk is k-bounded and Fℓ is ℓ-bounded. We show that the problem of deciding
whether a given graph has such a decomposition is NP-complete if both k and ℓ
are at least 2, NP-complete if k≥9 and ℓ=1, and is in P for (k,ℓ)=(2,1). Before
this, the only known NP-complete cases were the (2,2) and (3,3) cases. Our hardness
result answers a question of Bermond et al. from 1984. We also show that planar
graphs of girth at least nine decompose into a linear forest and a matching, which
in particular is stronger than 3-edge-colouring such graphs.

text: Characterizing the prevalence and properties of faint active galactic nuclei
(AGNs) in the early Universe is key for understanding the formation of supermassive
black holes (SMBHs) and determining their role in cosmic reionization. We perform
a spectroscopic search for broad Hα emitters at z ≈ 4–6 using deep JWST/NIRCam
imaging and wide field slitless spectroscopy from the EIGER and FRESCO surveys.
We identify 20 Hα lines at z = 4.2–5.5 that have broad components with line widths
from ∼1200–3700 km s−1, contributing ∼30%–90% of the total line flux. We interpret
these broad components as being powered by accretion onto SMBHs with implied masses
∼107–8M⊙. In the UV luminosity range MUV,AGN+host = −21 to −18, we measure number
densities of ≈10−5 cMpc−3. This is an order of magnitude higher than expected
from extrapolating quasar UV luminosity functions (LFs). Yet, such AGN are found
in only <1% of star-forming galaxies at z ∼ 5. The number density discrepancy
is much lower when compared to the broad Hα LF. The SMBH mass function agrees
with large cosmological simulations. In two objects, we detect complex Hα profiles
that we tentatively interpret as caused by absorption signatures from dense gas
fueling SMBH growth and outflows. We may be witnessing early AGN feedback that
will clear dust-free pathways through which more massive blue quasars are seen.
We uncover a strong correlation between reddening and the fraction of total galaxy
luminosity arising from faint AGN. This implies that early SMBH growth is highly
obscured and that faint AGN are only minor contributors to cosmic reionization.

text: The fungal bioluminescence pathway can be reconstituted in other organisms
allowing luminescence imaging without exogenously supplied substrate. The pathway
starts from hispidin biosynthesis—a step catalyzed by a large fungal polyketide
synthase that requires a posttranslational modification for activity. Here, we
report identification of alternative compact hispidin synthases encoded by a phylogenetically
diverse group of plants. A hybrid bioluminescence pathway that combines plant
and fungal genes is more compact, not dependent on availability of machinery for
posttranslational modifications, and confers autonomous bioluminescence in yeast,
mammalian, and plant hosts. The compact size of plant hispidin synthases enables
additional modes of delivery of autoluminescence, such as delivery with viral
vectors.

text: The elimination of rain evaporation in the planetary boundary layer (PBL)
has been found to lead to convective self‐aggregation (CSA) even without radiative
feedback, but the precise mechanisms underlying this phenomenon remain unclear.
We conducted cloud‐resolving simulations with two domain sizes and progressively
reduced rain evaporation in the PBL. Surprisingly, CSA only occurred when rain
evaporation was almost completely removed. The additional convective heating resulting
from the reduction of evaporative cooling in the moist patch was found to be the
trigger, thereafter a dry subsidence intrusion into the PBL in the dry patch takes
over and sets CSA in motion. Temperature and moisture anomalies oppose each other
in their buoyancy effects, hence explaining the need for almost total rain evaporation
removal. We also found radiative cooling and not cold pools to be the leading
cause for the comparative ease of CSA to take place in the larger domain.

text: We demonstrate the failure of the adiabatic Born-Oppenheimer approximation
to describe the ground state of a quantum impurity within an ultracold Fermi gas
despite substantial mass differences between the bath and impurity species. Increasing
repulsion leads to the appearance of nonadiabatic couplings between the fast bath
and slow impurity degrees of freedom, which reduce the parity symmetry of the
latter according to the pseudo Jahn-Teller effect. The presence of this mechanism
is associated to a conical intersection involving the impurity position and the
inverse of the interaction strength, which acts as a synthetic dimension. We elucidate
the presence of these effects via a detailed ground-state analysis involving the
comparison of ab initio fully correlated simulations with effective models. Our
study suggests ultracold atomic ensembles as potent emulators of complex molecular
phenomena.

text: Thermoelectric materials convert heat into electricity, with a broad range
of applications near room temperature (RT). However, the library of RT high-performance
materials is limited. Traditional high-temperature synthetic methods constrain
the range of materials achievable, hindering the ability to surpass crystal structure
limitations and engineer defects. Here, a solution-based synthetic approach is
introduced, enabling RT synthesis of powders and exploration of densification
at lower temperatures to influence the material's microstructure. The approach
is exemplified by Ag2Se, an n-type alternative to bismuth telluride. It is demonstrated
that the concentration of Ag interstitials, grain boundaries, and dislocations
are directly correlated to the sintering temperature, and achieve a figure of
merit of 1.1 from RT to 100 °C after optimization. Moreover, insights into and
resolve Ag2Se's challenges are provided, including stoichiometry issues leading
to irreproducible performances. This work highlights the potential of RT solution
synthesis in expanding the repertoire of high-performance thermoelectric materials
for practical applications.

text: Current knowledge suggests a drought Indian monsoon (perhaps a severe one)
when the El Nino Southern Oscillation and Pacific Decadal Oscillation each exhibit
positive phases (a joint positive phase). For the monsoons, which are exceptions
in this regard, we found northeast India often gets excess pre-monsoon rainfall.
Further investigation reveals that this excess pre-monsoon rainfall is produced
by the interaction of the large-scale circulation associated with the joint phase
with the mountains in northeast India. We posit that a warmer troposphere, a consequence
of excess rainfall over northeast India, drives a stronger monsoon circulation
and enhances monsoon rainfall over central India. Hence, we argue that pre-monsoon
rainfall over northeast India can be used for seasonal monsoon rainfall prediction
over central India. Most importantly, its predictive value is at its peak when
the Pacific Ocean exhibits a joint positive phase and the threat of extreme drought
monsoon looms over India.

text: The extracellular matrix (ECM) serves as a scaffold for cells and plays an
essential role in regulating numerous cellular processes, including cell migration
and proliferation. Due to limitations in specimen preparation for conventional
room-temperature electron microscopy, we lack structural knowledge on how ECM
components are secreted, remodeled, and interact with surrounding cells. We have
developed a 3D-ECM platform compatible with sample thinning by cryo-focused ion
beam milling, the lift-out extraction procedure, and cryo-electron tomography.
Our workflow implements cell-derived matrices (CDMs) grown on EM grids, resulting
in a versatile tool closely mimicking ECM environments. This allows us to visualize
ECM for the first time in its hydrated, native context. Our data reveal an intricate
network of extracellular fibers, their positioning relative to matrix-secreting
cells, and previously unresolved structural entities. Our workflow and results
add to the structural atlas of the ECM, providing novel insights into its secretion
and assembly.

text: We prove an upper bound on the ground state energy of the dilute spin-polarized
Fermi gas capturing the leading correction to the kinetic energy resulting from
repulsive interactions. One of the main ingredients in the proof is a rigorous
implementation of the fermionic cluster expansion of Gaudin et al. (1971) [15].

text: The mammary gland consists of a bilayered epithelial structure with an extensively
branched morphology. The majority of this epithelial tree is laid down during
puberty, during which actively proliferating terminal end buds repeatedly elongate
and bifurcate to form the basic structure of the ductal tree. Mammary ducts consist
of a basal and luminal cell layer with a multitude of identified sub-lineages
within both layers. The understanding of how these different cell lineages are
cooperatively driving branching morphogenesis is a problem of crossing multiple
scales, as this requires information on the macroscopic branched structure of
the gland, as well as data on single-cell dynamics driving the morphogenic program.
Here we describe a method to combine genetic lineage tracing with whole-gland
branching analysis. Quantitative data on the global organ structure can be used
to derive a model for mammary gland branching morphogenesis and provide a backbone
on which the dynamics of individual cell lineages can be simulated and compared
to lineage-tracing approaches. Eventually, these quantitative models and experiments
allow to understand the couplings between the macroscopic shape of the mammary
gland and the underlying single-cell dynamics driving branching morphogenesis.
