text: Identifying efficient active sites for the direct synthesis of hydrogen peroxide
over Pd-based catalysts has been a subject of considerable debate. In this study,
we employ particle swarm optimization method and density functional theory to
explore the H2O2 synthesis mechanism on Pd, PdO, and the partially oxidized surface
(Pd9OX). A comprehensive mechanism for Pd9OX is elucidated, and subsequent coverage-dependent
kinetic analysis allows for a quantitative assessment of catalytic performance
at the interphase. Our findings conclusively establish that the interphase between
Pd and PdO represents the optimal active site. Phase diagram analysis further
aids in determining stable structures under reaction conditions. At 298.15 K and
under oxygen balance, the Pd9O6 surface remains stable throughout the reaction,
demonstrating high activity and selectivity. This work underscores the significance
of the interphase in comprehending catalytic performance and unveils promising
avenues for optimizing catalyst performance by controlling reaction conditions
and surface composition.

text: "Locomotion is ubiquitous in the animal kingdom because an animal's survival
depends on its ability to navigate its environment to find food, avoid predators
and locate potential mates. These behaviours require control mechanisms that can
extract information from the environment, particularly visual cues. Selective
evolutionary pressures have thus refined such visuomotor transformations in a
species-specific manner to meet the specific ecological and ethological challenges
of each organism. However, a common challenge across organisms as visual information
processing\r\nbecomes increasingly detailed is the mechanisms required to synthesise
disparate pieces of information into a coherent percept or unified picture of
the world. In this thesis, I investigate how disparate visual information is combined
in the brain of Drosophila melanogaster to effectively guide locomotion.\r\nFor
this, I first designed and built a behavioural setup to record locomotion and
present visual stimuli to freely-walking fruit flies in a closed-loop manner.
This setup allowed the investigation of innate visually-guided behaviours, including
the optomotor reflex and courtship.\r\nSecond, taking advantage of my system I
investigated the optomotor response, a reflexive visual stabilisation behaviour
in which flies turn in the direction of global motion to minimise retinal slip.
This behaviour is thought to be mediated by Lobula plate tangential cells (LPTCs);
a complex network of optic-flow-sensitive neurons essential for self-motion estimation.
Using a novel genetic mutant, I demonstrate that electrical coupling between two
LPTC subtypes, contralateral HS and H2 neurons, regulates the balance between
smooth optomotor turning and saccadic anti-optomotor responses. These findings
underscore the critical role of binocular motion cue integration in guiding course
control. Finally, I developed a novel behavioural paradigm in which a sexually
aroused male fruit fly is presented with an optomotor distractor. This setup creates
competition between two visual behaviours, courtship tracking and the optomotor
response, enabling me to explore how the visual system resolves this conflict.
In this setting, males\r\nengaged in courtship selectively suppress their optomotor
response based on the female's location. Furthermore, when this experiment is
replicated with an “artificial female”, optogenetically aroused males alternate
between tracking and optomotor responses. The probability and dynamics of this
switching are determined by the relative strengths of the two competing stimuli.
In summary, the results presented in this thesis explore two mechanisms – integration
and competition - through which visual information is combined in the brain of
the fruit fly to drive locomotion."

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: Animals rely on compensatory actions to maintain stability and navigate their
environment efficiently. These actions depend on global visual motion cues known
as optic-flow. While the optomotor response has been the traditional focus for
studying optic-flow compensation in insects, its simplicity has been insufficient
to determine the role of the intricate optic-flow processing network involved
in visual course control. Here, we reveal a series of course control behaviours
in Drosophila and link them to specific neural circuits. We show that bilateral
electrical coupling of optic-flow-sensitive neurons in the fly’s lobula plate
are required for a proper course control. This electrical interaction works alongside
chemical synapses within the HS-H2 network to control the dynamics and direction
of turning behaviours. Our findings reveal how insects use bilateral motion cues
for navigation, assigning a new functional significance to the HS-H2 network and
suggesting a previously unknown role for gap junctions in non-linear operations.

text: We used diverse methods to characterize the role of avian lateral spiriform
nucleus (SpL) in basal ganglia motor function. Connectivity analysis showed that
SpL receives input from globus pallidus (GP), and the intrapeduncular nucleus
(INP) located ventromedial to GP, whose neurons express numerous striatal markers.
SpL-projecting GP neurons were large and aspiny, while SpL-projecting INP neurons
were medium sized and spiny. Connectivity analysis further showed that SpL receives
inputs from subthalamic nucleus (STN) and substantia nigra pars reticulata (SNr),
and that the SNr also receives inputs from GP, INP, and STN. Neurochemical analysis
showed that SpL neurons express ENK, GAD, and a variety of pallidal neuron markers,
and receive GABAergic terminals, some of which also contain DARPP32, consistent
with GP pallidal and INP striatal inputs. Connectivity and neurochemical analysis
showed that the SpL input to tectum prominently ends on GABAA receptor-enriched
tectobulbar neurons. Behavioral studies showed that lesions of SpL impair visuomotor
behaviors involving tracking and pecking moving targets. Our results suggest that
SpL modulates brainstem-projecting tectobulbar neurons in a manner comparable
to the demonstrated influence of GP internus on motor thalamus and of SNr on tectobulbar
neurons in mammals. Given published data in amphibians and reptiles, it seems
likely the SpL circuit represents a major direct pathway-type circuit by which
the basal ganglia exerts its motor influence in nonmammalian tetrapods. The present
studies also show that avian striatum is divided into three spatially segregated
territories with differing connectivity, a medial striato-nigral territory, a
dorsolateral striato-GP territory, and the ventrolateral INP motor territory.

text: "A thermoelectric cooler is a solid-state device that transfers heat from
one side to another when an electrical current passes through it. This technology
is appealing because it can provide precise and localized cooling and heating
without using hazardous liquids or gases commonly found in traditional vapor compression
refrigeration. These devices are compact, customizable in size, work in any orientation,
operate noiselessly, and require minimal maintenance. Even though thermoelectric
coolers could be transformative for many advanced thermal management applications,
their widespread adoption is hindered by the low efficiency of the thermoelectric
materials and costly manufacturing processes.\r\n In this work, we use extrusion-based
3D printing techniques to fabricate high-performance thermoelectric materials
using nanomaterial-based ink. The ink formulation is optimized to ensure structural
integrity and particle interfacial bonding during annealing, providing p- and
n-type materials with record-high zT values of 1.46 and 1.35 at room temperature,
respectively. Moreover, we integrate the printed materials into a 32-pair device
and achieve a significant cooling temperature gradient of 50 °C and a coefficient
of performance of 3.8, comparable to best-performing thermoelectric coolers, avoiding
material waste, and the energy-intense and inefficient steps, such as high-temperature
synthesis, pressure-assisted sintering, and cutting and dicing ingots, commonly
used in conventional manufacturing processes."

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: A detailed structural, magnetic as well as dielectric dynamics study is carried
out to investigate the influence of Bi3+ on YCrO3. All the samples crystalize
in orthorhombic structure with Pnma symmetry and the grains are mostly stretched
with Bi. A coexisting tunable fraction of both antiferromagnetic (AFM) and weak
ferromagnetic (WFM) phases is acquired by the system down to Low-T. An abnormal
negative magnetization in zero field is correlated to the competition among AFM
and WFM phases. Maximum magnetization decreases while the coercivity first increases
and then decreases with Bi is correlated to the competing effect between the local
deformation and Cr–O–Cr exchange interaction. The magnetodielectric coupling with
improved permittivity might be associated with the 6s2 lone pair electron of Bi3+.
Furthermore, ac-conductivity increases with a decrease in activation energy (0.27–0.11
eV), is explained in the framework of structural model and charge carrier hopping
between Cr3+ and Cr4+ ions.

text: 'MaxCut is a classical NP-complete problem and a crucial building block in
many combinatorial algorithms. The famous Edwards-Erdős bound states that any
connected graph on n vertices with m edges contains a cut of size at least m/2+(n-1)/4.
Crowston, Jones and Mnich [Algorithmica, 2015] showed that the MaxCut problem
on simple connected graphs admits an FPT algorithm, where the parameter k is the
difference between the desired cut size c and the lower bound given by the Edwards-Erdős
bound. This was later improved by Etscheid and Mnich [Algorithmica, 2017] to run
in parameterized linear time, i.e., f(k)⋅ O(m). We improve upon this result in
two ways: Firstly, we extend the algorithm to work also for multigraphs (alternatively,
graphs with positive integer weights). Secondly, we change the parameter; instead
of the difference to the Edwards-Erdős bound, we use the difference to the Poljak-Turzík
bound. The Poljak-Turzík bound states that any weighted graph G has a cut of size
at least (w(G))/2+(w_MSF(G))/4, where w(G) denotes the total weight of G, and
w_MSF(G) denotes the weight of its minimum spanning forest. In connected simple
graphs the two bounds are equivalent, but for multigraphs the Poljak-Turzík bound
can be larger and thus yield a smaller parameter k. Our algorithm also runs in
parameterized linear time, i.e., f(k)⋅ O(m+n).'

text: "There are a number of well-known problems and conjectures about partitioning
graphs to satisfy local constraints. For example, the majority colouring conjecture
of Kreutzer, Oum, Seymour, van der Zypen and Wood states that every directed graph
has a 3-colouring such that for every vertex v, at most half of the out-neighbours
of v have the same colour as \r\n. As another example, the internal partition
conjecture, due to DeVos and to Ban and Linial, states that for every d, all but
finitely many d-regular graphs have a partition into two non-empty parts such
that for every vertex v, at least half of the neighbours of v lie in the same
part as v. We prove several results in this spirit: in particular, two of our
results are that the majority colouring conjecture holds for Erdős–Rényi random
directed graphs (of any density), and that the internal partition conjecture holds
if we permit a tiny number of ‘exceptional vertices’. Our proofs involve a variety
of techniques, including several different methods to analyse random recolouring
processes. One highlight is a personality-changing scheme: we ‘forget’ certain
information based on the state of a Markov chain, giving us more independence
to work with."

text: "The inertia bound and ratio bound (also known as the Cvetković bound and
Hoffman bound) are two fundamental inequalities in spectral graph theory, giving
upper bounds on the independence number α(G) of a graph G in terms of spectral
information about a weighted adjacency matrix of G. For both inequalities, given
a graph G, one needs to make a judicious choice of weighted adjacency matrix to
obtain as strong a bound as possible.\r\nWhile there is a well-established theory
surrounding the ratio bound, the inertia bound is much more mysterious, and its
limits are rather unclear. In fact, only recently did Sinkovic find the first
example of a graph for which the inertia bound is not tight (for any weighted
adjacency matrix), answering a longstanding question of Godsil. We show that the
inertia bound can be extremely far from tight, and in fact can significantly underperform
the ratio bound: for example, one of our results is that for infinitely many n,
there is an n-vertex graph for which even the unweighted ratio bound can prove
α(G)≤4n3/4, but the inertia bound is always at least n/4. In particular, these
results address questions of Rooney, Sinkovic, and Wocjan--Elphick--Abiad."

text: "Let Qd be the d-dimensional binary hypercube. We say that P={v1,…,vk} is
an increasing path of length k−1 in Qd, if for every i∈[k−1] the edge vivi+1 is
obtained by switching some zero coordinate in vi to a one coordinate in vi+1.\r\nForm
a random subgraph Qdp by retaining each edge in E(Qd) independently with probability
p. We show that there is a phase transition with respect to the length of a longest
increasing path around p=ed. Let α be a constant and let p=αd. When αe, whp there is a path of length d−2 in
Qdp, and in fact, whether it is of length d−2,d−1, or d depends on whether the
all-zero and all-one vertices percolate or not."

text: "We consider local dynamics of the dimer model (perfect matchings) on hypercubic
boxes [n] \r\nd . These consist of successively switching the dimers along alternating
cycles of prescribed (small) lengths. We study the connectivity properties of
the dimer configuration space equipped with these transitions. Answering a question
of Freire, Klivans, Milet, and Saldanha, we show that in three dimensions any
configuration admits an alternating cycle of length at most 6. We further establish
that any configuration on [n] d features order n d−2 alternating cycles of length
at most 4d−2. We also prove that the dynamics of dimer configurations on the unit
hypercube of dimension d is ergodic when switching alternating cycles of length
at most 4d−4. Finally, in the planar but non-bipartite case, we show that parallelogram-shaped
boxes in the triangular lattice are ergodic for switching alternating cycles of
lengths 4 and 6 only, thus improving a result of Kenyon and Rémila, which also
uses 8-cycles. None of our proofs make reference to height functions."

text: The synthesis of proteins as encoded in the genome depends critically on translational
fidelity. Nevertheless, errors inevitably occur, and those that result in reading
frame shifts are particularly consequential because the resulting polypeptides
are typically nonfunctional. Despite the generally maladaptive impact of such
errors, the proper decoding of certain mRNAs, including many viral mRNAs, depends
on a process known as programmed ribosomal frameshifting. The fact that these
programmed events, commonly involving a shift to the –1 frame, occur at specific
evolutionarily optimized “slippery” sites has facilitated mechanistic investigation.
By contrast, less is known about the scope and nature of error (i.e., nonprogrammed)
frameshifting. Here, we examine error frameshifting by monitoring spontaneous
frameshift events that suppress the effects of single base pair deletions affecting
two unrelated test proteins. To map the precise sites of frameshifting, we developed
a targeted mass spectrometry–based method called “translational tiling proteomics”
for interrogating the full set of possible –1 slippage events that could produce
the observed frameshift suppression. Surprisingly, such events occur at many sites
along the transcripts, involving up to one half of the available codons. Only
a subset of these resembled canonical “slippery” sites, implicating alternative
mechanisms potentially involving noncognate mispairing events. Additionally, the
aggregate frequency of these events (ranging from 1 to 10% in our test cases)
was higher than we might have anticipated. Our findings point to an unexpected
degree of mechanistic diversity among ribosomal frameshifting events and suggest
that frameshifted products may contribute more significantly to the proteome than
generally assumed.

text: Conserved signaling cascades monitor protein-folding homeostasis to ensure
proper cellular function. One of the evolutionary conserved key players is IRE1,
which maintains endoplasmic reticulum (ER) homeostasis through the unfolded protein
response (UPR). Upon accumulation of misfolded proteins in the ER, IRE1 forms
clusters on the ER membrane to initiate UPR signaling. What regulates IRE1 cluster
formation is not fully understood. Here, we show that the ER lumenal domain (LD)
of human IRE1α forms biomolecular condensates in vitro. IRE1α LD condensates were
stabilized both by binding to unfolded polypeptides as well as by tethering to
model membranes, suggesting their role in assembling IRE1α into signaling-competent
stable clusters. Molecular dynamics simulations indicated that weak multivalent
interactions drive IRE1α LD clustering. Mutagenesis experiments identified disordered
regions in IRE1α LD to control its clustering in vitro and in cells. Importantly,
dysregulated clustering of IRE1α mutants led to defects in IRE1α signaling. Our
results revealed that disordered regions in IRE1α LD control its clustering and
suggest their role as a common strategy in regulating protein assembly on membranes.

text: Bacteria divide by binary fission. The protein machine responsible for this
process is the divisome, a transient assembly of more than 30 proteins in and
on the surface of the cytoplasmic membrane. Together, they constrict the cell
envelope and remodel the peptidoglycan layer to eventually split the cell into
two. For Escherichia coli, most molecular players involved in this process have
probably been identified, but obtaining the quantitative information needed for
a mechanistic understanding can often not be achieved from experiments in vivo
alone. Since the discovery of the Z-ring more than 30 years ago, in vitro reconstitution
experiments have been crucial to shed light on molecular processes normally hidden
in the complex environment of the living cell. In this review, we summarize how
rebuilding the divisome from purified components – or at least parts of it - have
been instrumental to obtain the detailed mechanistic understanding of the bacterial
cell division machinery that we have today.

text: 'In this work we prove lower bounds on the (communication) cost of maintaining
a shared key among a dynamic group of users. Being “dynamic” means one can add
and remove users from the group. This captures important protocols like multicast
encryption (ME) and continuous group-key agreement (CGKA), which is the primitive
underlying many group messaging applications. We prove our bounds in a combinatorial
setting where the state of the protocol progresses in rounds. The state of the
protocol in each round is captured by a set system, with each of its elements
specifying a set of users who share a secret key. We show this combinatorial model
implies bounds in symbolic models for ME and CGKA that capture, as building blocks,
PRGs, PRFs, dual PRFs, secret sharing, and symmetric encryption in the setting
of ME, and PRGs, PRFs, dual PRFs, secret sharing, public-key encryption, and key-updatable
public-key encryption in the setting of CGKA. The models are related to the ones
used by Micciancio and Panjwani (Eurocrypt’04) and Bienstock et al. (TCC’20) to
analyze ME and CGKA, respectively. We prove – using the Bollobás’ Set Pairs Inequality
– that the cost (number of uploaded ciphertexts) for replacing a set of d users
in a group of size n is Ω(dln(n/d)). Our lower bound is asymptotically tight and
both improves on a bound of Ω(d) by Bienstock et al. (TCC’20), and generalizes
a result by Micciancio and Panjwani (Eurocrypt’04), who proved a lower bound of
Ω(log(n)) for d=1. '

text: "As a discrete analogue of Kac’s celebrated question on ‘hearing the shape
of a drum’ and towards a practical\r\ngraph isomorphism test, it is of interest
to understand which graphs are determined up to isomorphism by\r\ntheir spectrum
(of their adjacency matrix). A striking conjecture in this area, due to van Dam
and Haemers,\r\nis that ‘almost all graphs are determined by their spectrum’,
meaning that the fraction of unlabelled n-vertex\r\ngraphs which are determined
by their spectrum converges to 1 as n → ∞.\r\nIn this paper, we make a step towards
this conjecture, showing that there are exponentially many n-vertex\r\ngraphs
which are determined by their spectrum. This improves on previous bounds (of shape
e\r\nc\r\n√\r\nn\r\n). We also\r\npropose a number of further directions of research.\r\n"
