text: 'Mass spectrometry imaging (MSI) is a powerful analytical technique for the
two-dimensional (2D) localization of chemicals on surfaces. Conventional MSI experiments
require to predefine the surface of interest based on photographic or microscopic
images. Typically, these boundaries can no longer be changed or adjusted once
the experiment has been started. In terms of a more interactive approach we recently
developed a pen-like ionization interface which is directly connected to the mass
spectrometer. The device allows the user to ionize chemicals by desorption electrospray
ionization (DESI) and to freely move the interface over a surface of interest.
A mini camera, which is mounted on the tip of the pen, magnifies the desorption
area and enables a simple positioning of the pen. The combination of optical data
from the camera module and chemical data obtained by mass analysis facilitates
a novel type of imaging experiment: interactive mass spectrometry imaging (IMSI).
For this application, we present a novel approach for a robust, optical flow-based
motion detection. While the live video stream from the camera is used to track
the pen''s motion across the surface a post-acquisition algorithm correlates the
coordinates of the pen trajectory with respective mass spectra obtained from a
simultaneous mass spectrometric data acquisition. This algorithm is no longer
dependent on a single, manually applied optical marker on the sample surface,
which has to be visible on all video frames throughout the analysis. The advanced
DESI-IMSI method was successfully tested on inkjet-printed letters as well as
mouse brain tissue samples. Validation of the results was done by comparing DESI-IMSI
with standard DESI-MSI data.'

text: Two assumptions commonly applied in convection schemes—the diagnostic and
quasi-equilibrium assumptions—imply that convective activity (e.g., convective
precipitation) is controlled only by the large-scale (macrostate) environment
at the time. In contrast, numerical experiments indicate a “memory” or dependence
of convection also on its own previous activity whereby subgrid-scale (microstate)
structures boost but are also boosted by convection. In this study we investigated
this memory by comparing single-column model behavior in two idealized tests previously
executed by a cloud-resolving model (CRM). Conventional convection schemes that
employ the diagnostic assumption fail to reproduce the CRM behavior. The memory-capable
org and Laboratoire de Météorologie Dynamique Zoom cold pool schemes partially
capture the behavior, but fail to fully exhibit the strong reinforcing feedbacks
implied by the CRM. Analysis of this failure suggests that it is because the CRM
supports a linear (or superlinear) dependence of the subgrid structure growth
rate on the precipitation rate, while the org scheme assumes a sublinear dependence.
Among varying versions of the org scheme, the growth rate of the org variable
representing subgrid structure is strongly associated with memory strength. These
results demonstrate the importance of parameterizing convective memory, and the
ability of idealized tests to reveal shortcomings of convection schemes and constrain
model structural assumptions.

text: The kinetics of the assembly of semiflexible filaments through end-to-end
annealing is key to the structure of the cytoskeleton, but is not understood.
We analyze this problem through scaling theory and simulations, and uncover a
regime where filaments’ ends find each other through bending fluctuations without
the need for the whole filament to diffuse. This results in a very substantial
speedup of assembly in physiological regimes, and could help with understanding
the dynamics of actin and intermediate filaments in biological processes such
as wound healing and cell division.

text: Although much is known about how single neurons in the hippocampus represent
an animal's position, how circuit interactions contribute to spatial coding is
less well understood. Using a novel statistical estimator and theoretical modeling,
both developed in the framework of maximum entropy models, we reveal highly structured
CA1 cell-cell interactions in male rats during open field exploration. The statistics
of these interactions depend on whether the animal is in a familiar or novel environment.
In both conditions the circuit interactions optimize the encoding of spatial information,
but for regimes that differ in the informativeness of their spatial inputs. This
structure facilitates linear decodability, making the information easy to read
out by downstream circuits. Overall, our findings suggest that the efficient coding
hypothesis is not only applicable to individual neuron properties in the sensory
periphery, but also to neural interactions in the central brain.

text: 'Natural selection is usually studied between mutants that differ in reproductive
rate, but are subject to the same population structure. Here we explore how natural
selection acts on mutants that have the same reproductive rate, but different
population structures. In our framework, population structure is given by a graph
that specifies where offspring can disperse. The invading mutant disperses offspring
on a different graph than the resident wild-type. We find that more densely connected
dispersal graphs tend to increase the invader’s fixation probability, but the
exact relationship between structure and fixation probability is subtle. We present
three main results. First, we prove that if both invader and resident are on complete
dispersal graphs, then removing a single edge in the invader’s dispersal graph
reduces its fixation probability. Second, we show that for certain island models
higher invader’s connectivity increases its fixation probability, but the magnitude
of the effect depends on the exact layout of the connections. Third, we show that
for lattices the effect of different connectivity is comparable to that of different
fitness: for large population size, the invader’s fixation probability is either
constant or exponentially small, depending on whether it is more or less connected
than the resident.'

text: "We investigate spin-charge separation of a spin-\r\n1\r\n2\r\n Fermi system
confined in a triple well where multiple bands are occupied. We assume that our
finite fermionic system is close to fully spin polarized while being doped by
a hole and an impurity fermion with opposite spin. Our setup involves ferromagnetic
couplings among the particles in different bands, leading to the development of
strong spin-transport correlations in an intermediate interaction regime. Interactions
are then strong enough to lift the degeneracy among singlet and triplet spin configurations
in the well of the spin impurity but not strong enough to prohibit hole-induced
magnetic excitations to the singlet state. Despite the strong spin-hole correlations,
the system exhibits spin-charge deconfinement allowing for long-range entanglement
of the spatial and spin degrees of freedom."

text: Understanding the response of Himalayan glaciers to global warming is vital
because of their role as a water source for the Asian subcontinent. However, great
uncertainties still exist on the climate drivers of past and present glacier changes
across scales. Here, we analyse continuous hourly climate station data from a
glacierized elevation (Pyramid station, Mount Everest) since 1994 together with
other ground observations and climate reanalysis. We show that a decrease in maximum
air temperature and precipitation occurred during the last three decades at Pyramid
in response to global warming. Reanalysis data suggest a broader occurrence of
this effect in the glacierized areas of the Himalaya. We hypothesize that the
counterintuitive cooling is caused by enhanced sensible heat exchange and the
associated increase in glacier katabatic wind, which draws cool air downward from
higher elevations. The stronger katabatic winds have also lowered the elevation
of local wind convergence, thereby diminishing precipitation in glacial areas
and negatively affecting glacier mass balance. This local cooling may have partially
preserved glaciers from melting and could help protect the periglacial environment.

text: "The classical Steinitz theorem states that if the origin belongs to the interior
of the convex hull of a set \U0001D446⊂ℝ\U0001D451, then there are at most 2\U0001D451
points of \U0001D446 whose convex hull contains the origin in the interior. Bárány,
Katchalski,and Pach proved the following quantitative version of Steinitz’s theorem.
Let \U0001D444 be a convex polytope in ℝ\U0001D451 containing the standard Euclidean
unit ball \U0001D401\U0001D451. Then there exist at most 2\U0001D451 vertices
of \U0001D444 whose convex hull \U0001D444′ satisfies \U0001D45F\U0001D401\U0001D451⊂\U0001D444′
with \U0001D45F⩾\U0001D451−2\U0001D451. They conjectured that \U0001D45F⩾\U0001D450\U0001D451−1∕2
holds with a universal constant \U0001D450>0. We prove \U0001D45F⩾15\U0001D4512,
the first polynomial lower bound on \U0001D45F. Furthermore, we show that \U0001D45F
is not greater than 2/√\U0001D451."

text: 'This paper is concerned with equilibrium configurations of one-dimensional
particle systems with non-convex nearest-neighbour and next-to-nearest-neighbour
interactions and its passage to the continuum. The goal is to derive compactness
results for a Γ-development of the energy with the novelty that external forces
are allowed. In particular, the forces may depend on Lagrangian or Eulerian coordinates
and thus may model dead as well as live loads. Our result is based on a new technique
for deriving compactness results which are required for calculating the first-order
Γ-limit in the presence of external forces: instead of comparing a configuration
of n atoms to a global minimizer of the Γ-limit, we compare the configuration
to a minimizer in some subclass of functions which in some sense are "close to"
the configuration. The paper is complemented with the study of the minimizers
of the Γ-limit.'

text: As a bottleneck in the direct synthesis of hydrogen peroxide, the development
of an efficient palladium-based catalyst has garnered great attention. However,
elusive active centers and reaction mechanism issues inhibit further optimization
of its performance. In this work, advanced microkinetic modeling with the adsorbate–adsorbate
interaction and nanoparticle size effect based on first-principles calculations
is developed. A full mechanism uncovering the significance of adsorbate–adsorbate
interaction is determined on Pd nanoparticles. We demonstrate unambiguously that
Pd(100) with main coverage species of O2 and H is beneficial to H2O2 production,
being consistent with experimental operando observation, while H2O forms on Pd(111)
covered by O species and Pd(211) covered by O and OH species. Kinetic analyses
further enable quantitative estimation of the influence of temperature, pressure,
and particle size. Large-size Pd nanoparticles are found to achieve a high H2O2
reaction rate when the operating conditions are moderate temperature and higher
oxygen partial pressure. We reveal that specific facets of the Pd nanoparticles
are crucial factors for their selectivity and activity. Consistent with the experiment,
the production of H2O2 is discovered to be more favorable on Pd nanoparticles
containing Pd(100) facets. The ratio of H2/O2 induces substantial variations in
the coverage of intermediates of O2 and H on Pd(100), resulting in a change in
product selectivity.

text: The architecture of self-assembled host molecules can profoundly affect the
properties of the encapsulated guests. For example, a rigid cage with small windows
can efficiently protect its contents from the environment; in contrast, tube-shaped,
flexible hosts with large openings and an easily accessible cavity are ideally
suited for catalysis. Here, we report a “Janus” nature of a Pd6L4 coordination
host previously reported to exist exclusively as a tube isomer (T). We show that
upon encapsulating various tetrahedrally shaped guests, T can reconfigure into
a cage-shaped host (C) in quantitative yield. Extracting the guest affords empty
C, which is metastable and spontaneously relaxes to T, and the T⇄C interconversion
can be repeated for multiple cycles. Reversible toggling between two vastly different
isomers paves the way toward controlling functional properties of coordination
hosts “on demand”.

text: We derive lower bounds on the maximal rates for multiple packings in high-dimensional
Euclidean spaces. For any N > 0 and L ∈ Z ≥2 , a multiple packing is a set C of
points in R n such that any point in R n lies in the intersection of at most L
- 1 balls of radius √ nN around points in C . This is a natural generalization
of the sphere packing problem. We study the multiple packing problem for both
bounded point sets whose points have norm at most √ nP for some constant P > 0,
and unbounded point sets whose points are allowed to be anywhere in R n . Given
a well-known connection with coding theory, multiple packings can be viewed as
the Euclidean analog of list-decodable codes, which are well-studied over finite
fields. We derive the best known lower bounds on the optimal multiple packing
density. This is accomplished by establishing an inequality which relates the
list-decoding error exponent for additive white Gaussian noise channels, a quantity
of average-case nature, to the list-decoding radius, a quantity of worst-case
nature. We also derive novel bounds on the list-decoding error exponent for infinite
constellations and closed-form expressions for the list-decoding error exponents
for the power-constrained AWGN channel, which may be of independent interest beyond
multiple packing.

text: So-called spontaneous activity is a central hallmark of most nervous systems.
Such non-causal firing is contrary to the tenet of spikes as a means of communication,
and its purpose remains unclear. We propose that self-initiated firing can serve
as a release valve to protect neurons from the toxic conditions arising in mitochondria
from lower-than-baseline energy consumption. To demonstrate the viability of our
hypothesis, we built a set of models that incorporate recent experimental results
indicating homeostatic control of metabolic products—Adenosine triphosphate (ATP),
adenosine diphosphate (ADP), and reactive oxygen species (ROS)—by changes in firing.
We explore the relationship of metabolic cost of spiking with its effect on the
temporal patterning of spikes and reproduce experimentally observed changes in
intrinsic firing in the fruitfly dorsal fan-shaped body neuron in a model with
ROS-modulated potassium channels. We also show that metabolic spiking homeostasis
can produce indefinitely sustained avalanche dynamics in cortical circuits. Our
theory can account for key features of neuronal activity observed in many studies
ranging from ion channel function all the way to resting state dynamics. We finish
with a set of experimental predictions that would confirm an integrated, crucial
role for metabolically regulated spiking and firmly link metabolic homeostasis
and neuronal function.

text: 'For large dimensional non-Hermitian random matrices X with real or complex
independent, identically distributed, centered entries, we consider the fluctuations
of f (X) as a matrix where f is an analytic function around the spectrum of X.
We prove that for a generic bounded square matrix A, the quantity Tr f (X)A exhibits
Gaussian fluctuations as the matrix size grows to infinity, which consists of
two independent modes corresponding to the tracial and traceless parts of A. We
find a new formula for the variance of the traceless part that involves the Frobenius
norm of A and the L2-norm of f on the boundary of the limiting spectrum. '

of genetic mosaic tissue in mice and high-resolution phenotyping at the individual
cell level. Here, we present a protocol for isolating MADM-labeled cells with
high yield for downstream molecular analyses using fluorescence-activated cell
sorting (FACS). We describe steps for generating MADM-labeled mice, perfusion,
single-cell suspension, and debris removal. We then detail procedures for cell
sorting by FACS and downstream analysis. This protocol is suitable for embryonic

text: The short history of research on Li-O2 batteries has seen a remarkable number
of mechanistic U-turns over the years. From the initial use of carbonate electrolytes,
that were then found to be entirely unsuitable, to the belief that (su)peroxide
was solely responsible for degradation, before the more reactive singlet oxygen
was found to form, to the hypothesis that capacity depends on a competing surface/solution
mechanism before a practically exclusive solution mechanism was identified. Herein,
we argue for an ever-fresh look at the reported data without bias towards supposedly
established explanations. We explain how the latest findings on rate and capacity
limits, as well as the origin of side reactions, are connected via the disproportionation
(DISP) step in the (dis)charge mechanism. Therefrom, directions emerge for the
design of electrolytes and mediators on how to suppress side reactions and to
enable high rate and high reversible capacity.

text: Generalized multifractality characterizes system size dependence of pure scaling
local observables at Anderson transitions in all 10 symmetry classes of disordered
systems. Recently, the concept of generalized multifractality has been extended
to boundaries of critical disordered noninteracting systems. Here we study the
generalized boundary multifractality in the presence of electron-electron interaction,
focusing on the spin quantum Hall symmetry class (class C). Employing the two-loop
renormalization group analysis within the Finkel'stein nonlinear sigma model,
we compute the anomalous dimensions of the pure scaling operators located at the
boundary of the system. We find that generalized boundary multifractal exponents
are twice larger than their bulk counterparts. Exact symmetry relations between
generalized boundary multifractal exponents in the case of noninteracting systems
are explicitly broken by the interaction.

messaging by the IETF. CKGA works in an asynchronous setting where parties only
occasionally must come online, and their messages are relayed by an untrusted
server. The most expensive operation provided by CKGA is that which allows for
a user to refresh their key material in order to achieve forward secrecy (old
messages are secure when a user is compromised) and post-compromise security (users
can heal from compromise). One caveat of early CGKA protocols is that these update
operations had to be performed sequentially, with any user wanting to update their
key material having had to receive and process all previous updates. Late versions
of TreeKEM do allow for concurrent updates at the cost of a communication overhead
per update message that is linear in the number of updating parties. This was
shown to be indeed necessary when achieving PCS in just two rounds of communication
by [Bienstock et al. TCC’20].\r\nThe recently proposed protocol CoCoA [Alwen et
al. Eurocrypt’22], however, shows that this overhead can be reduced if PCS requirements
are relaxed, and only a logarithmic number of rounds is required. The natural
question, thus, is whether CoCoA is optimal in this setting.\r\nIn this work we
answer this question, providing a lower bound on the cost (concretely, the amount
of data to be uploaded to the server) for CGKA protocols that heal in an arbitrary
k number of rounds, that shows that CoCoA is very close to optimal. Additionally,
we extend CoCoA to heal in an arbitrary number of rounds, and propose a modification
of it, with a reduced communication cost for certain k.\r\nWe prove our bound
in a combinatorial setting where the state of the protocol progresses in rounds,
and the state of the protocol in each round is captured by a set system, each
set specifying a set of users who share a secret key. We show this combinatorial
model is equivalent to a symbolic model capturing building blocks including PRFs
and public-key encryption, related to the one used by Bienstock et al.\r\nOur
lower bound is of order k•n1+1/(k-1)/log(k), where 2≤k≤log(n) is the number of
updates per user the protocol requires to heal. This generalizes the n2 bound
for k=2 from Bienstock et al.. This bound almost matches the k⋅n1+2/(k-1) or k2⋅n1+1/(k-1)
efficiency we get for the variants of the CoCoA protocol also introduced in this
paper."

text: "The generic-group model (GGM) aims to capture algorithms working over groups
of prime order that only rely on the group operation, but do not exploit any additional
structure given by the concrete implementation of the group. In it, it is possible
to prove information-theoretic lower bounds on the hardness of problems like the
discrete logarithm (DL) or computational Diffie-Hellman (CDH). Thus, since its
introduction, it has served as a valuable tool to assess the concrete security
provided by cryptographic schemes based on such problems. A work on the related
algebraic-group model (AGM) introduced a method, used by many subsequent works,
to adapt GGM lower bounds for one problem to another, by means of conceptually
simple reductions.\r\nIn this work, we propose an alternative approach to extend
GGM bounds from one problem to another. Following an idea by Yun [EC15], we show
that, in the GGM, the security of a large class of problems can be reduced to
that of geometric search-problems. By reducing the security of the resulting geometric-search
problems to variants of the search-by-hypersurface problem, for which information
theoretic lower bounds exist, we give alternative proofs of several results that
used the AGM approach.\r\nThe main advantage of our approach is that our reduction
from geometric search-problems works, as well, for the GGM with preprocessing
(more precisely the bit-fixing GGM introduced by Coretti, Dodis and Guo [Crypto18]).
As a consequence, this opens up the possibility of transferring preprocessing
GGM bounds from one problem to another, also by means of simple reductions. Concretely,
we prove novel preprocessing bounds on the hardness of the d-strong discrete logarithm,
the d-strong Diffie-Hellman inversion, and multi-instance CDH problems, as well
as a large class of Uber assumptions. Additionally, our approach applies to Shoup’s
GGM without additional restrictions on the query behavior of the adversary, while
the recent works of Zhang, Zhou, and Katz [AC22] and Zhandry [Crypto22] highlight
that this is not the case for the AGM approach."
