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).'

abstract:

text: Primary implant stability, which refers to the stability of the implant during
the initial healing period is a crucial factor in determining the long-term success
of the implant and lays the foundation for secondary implant stability achieved
through osseointegration. Factors affecting primary stability include implant
design, surgical technique, and patient-specific factors like bone quality and
morphology. In vivo, the cyclic nature of anatomical loading puts osteosynthesis
locking screws under dynamic loads, which can lead to the formation of micro cracks
and defects that slowly degrade the mechanical connection between the bone and
screw, thus compromising the initial stability and secondary stability of the
implant. Monotonic quasi-static loading used for testing the holding capacity
of implanted screws is not well suited to capture this behavior since it cannot
capture the progressive deterioration of peri‑implant bone at small displacements.
In order to address this issue, this study aims to determine a critical point
of loss of primary implant stability in osteosynthesis locking screws under cyclic
overloading by investigating the evolution of damage, dissipated energy, and permanent
deformation. A custom-made test setup was used to test implanted 2.5 mm locking
screws under cyclic overloading test. For each loading cycle, maximum forces and
displacement were recorded as well as initial and final cycle displacements and
used to calculate damage and energy dissipation evolution. The results of this
study demonstrate that for axial, shear, and mixed loading significant damage
and energy dissipation can be observed at approximately 20 % of the failure force.
Additionally, at this load level, permanent deformations on the screw-bone interface
were found to be in the range of 50 to 150 mm which promotes osseointegration
and secondary implant stability. This research can assist surgeons in making informed
preoperative decisions by providing a better understanding of the critical point
of loss of primary implant stability, thus improving the long-term success of
the implant and overall patient satisfaction.

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.
