text: In recent years, significant advances have been made in the design and analysis
of fully dynamic algorithms. However, these theoretical results have received
very little attention from the practical perspective. Few of the algorithms are
implemented and tested on real datasets, and their practical potential is far
from understood. Here, we present a quick reference guide to recent engineering
and theory results in the area of fully dynamic graph algorithms.

text: "This paper presents a comprehensive study of algorithms for maintaining the
number of all connected four-vertex subgraphs in a dynamic graph. Specifically,
our algorithms maintain the number of paths of length three in deterministic amortized
O(m^{1/2}) update time, and any other connected four-vertex subgraph which is
not a clique in deterministic amortized update time O(m^{2/3}). Queries can be
answered in constant time. We also study the query times for subgraphs containing
an arbitrary edge that is supplied only with the query as well as the case where
only subgraphs containing a vertex s that is fixed beforehand are considered.
For length-3 paths, paws, 4-cycles, and diamonds our bounds match or are not far
from (conditional) lower bounds: Based on the OMv conjecture we show that any
dynamic algorithm that detects the existence of paws, diamonds, or 4-cycles or
that counts length-3 paths takes update time Ω(m^{1/2-δ}).\r\nAdditionally, for
4-cliques and all connected induced subgraphs, we show a lower bound of Ω(m^{1-δ})
for any small constant δ > 0 for the amortized update time, assuming the static
combinatorial 4-clique conjecture holds. This shows that the O(m) algorithm by
Eppstein et al. [David Eppstein et al., 2012] for these subgraphs cannot be improved
by a polynomial factor."

text: Primary nucleation is the fundamental event that initiates the conversion
of proteins from their normal physiological forms into pathological amyloid aggregates
associated with the onset and development of disorders including systemic amyloidosis,
as well as the neurodegenerative conditions Alzheimer’s and Parkinson’s diseases.
It has become apparent that the presence of surfaces can dramatically modulate
nucleation. However, the underlying physicochemical parameters governing this
process have been challenging to elucidate, with interfaces in some cases having
been found to accelerate aggregation, while in others they can inhibit the kinetics
of this process. Here we show through kinetic analysis that for three different
fibril-forming proteins, interfaces affect the aggregation reaction mainly through
modulating the primary nucleation step. Moreover, we show through direct measurements
of the Gibbs free energy of adsorption, combined with theory and coarse-grained
computer simulations, that overall nucleation rates are suppressed at high and
at low surface interaction strengths but significantly enhanced at intermediate
strengths, and we verify these regimes experimentally. Taken together, these results
provide a quantitative description of the fundamental process which triggers amyloid
formation and shed light on the key factors that control this process.

text: We consider the flow of two viscous and incompressible fluids within a bounded
domain modeled by means of a two-phase Navier–Stokes system. The two fluids are
assumed to be immiscible, meaning that they are separated by an interface. With
respect to the motion of the interface, we consider pure transport by the fluid
flow. Along the boundary of the domain, a complete slip boundary condition for
the fluid velocities and a constant ninety degree contact angle condition for
the interface are assumed. In the present work, we devise for the resulting evolution
problem a suitable weak solution concept based on the framework of varifolds and
establish as the main result a weak-strong uniqueness principle in 2D. The proof
is based on a relative entropy argument and requires a non-trivial further development
of ideas from the recent work of Fischer and the first author (Arch. Ration. Mech.
Anal. 236, 2020) to incorporate the contact angle condition. To focus on the effects
of the necessarily singular geometry of the evolving fluid domains, we work for
simplicity in the regime of same viscosities for the two fluids.

text: "In the stochastic population protocol model, we are given a connected graph
with n nodes, and in every time step, a scheduler samples an edge of the graph
uniformly at random and the nodes connected by this edge interact. A fundamental
task in this model is stable leader election, in which all nodes start in an identical
state and the aim is to reach a configuration in which (1) exactly one node is
elected as leader and (2) this node remains as the unique leader no matter what
sequence of interactions follows. On cliques, the complexity of this problem has
recently been settled: time-optimal protocols stabilize in Θ(n log n) expected
steps using Θ(log log n) states, whereas protocols that use O(1) states require
Θ(n2) expected steps.\r\n\r\nIn this work, we investigate the complexity of stable
leader election on general graphs. We provide the first non-trivial time lower
bounds for leader election on general graphs, showing that, when moving beyond
cliques, the complexity landscape of leader election becomes very diverse: the
time required to elect a leader can range from O(1) to Θ(n3) expected steps. On
the upper bound side, we first observe that there exists a protocol that is time-optimal
on many graph families, but uses polynomially-many states. In contrast, we give
a near-time-optimal protocol that uses only O(log2n) states that is at most a
factor log n slower. Finally, we show that the constant-state protocol of Beauquier
et al. [OPODIS 2013] is at most a factor n log n slower than the fast polynomial-state
protocol. Moreover, among constant-state protocols, this protocol has near-optimal
average case complexity on dense random graphs."

text: "This paper is a continuation of Part I of this project, where we developed
a new local well-posedness theory for nonlinear stochastic PDEs with Gaussian
noise. In the current Part II we consider blow-up criteria and regularization
phenomena. As in Part I we can allow nonlinearities with polynomial growth and
rough initial values from critical spaces. In the first main result we obtain
several new blow-up criteria for quasi- and semilinear stochastic evolution equations.
In particular, for semilinear equations we obtain a Serrin type blow-up criterium,
which extends a recent result of Prüss–Simonett–Wilke (J Differ Equ 264(3):2028–2074,
2018) to the stochastic setting. Blow-up criteria can be used to prove global
well-posedness for SPDEs. As in Part I, maximal regularity techniques and weights
in time play a central role in the proofs. Our second contribution is a new method
to bootstrap Sobolev and Hölder regularity in time and space, which does not require
smoothness of the initial data. The blow-up criteria are at the basis of these
new methods. Moreover, in applications the bootstrap results can be combined with
our blow-up criteria, to obtain efficient ways to prove global existence. This
gives new results even in classical \U0001D43F2-settings, which we illustrate
for a concrete SPDE. In future works in preparation we apply the results of the
current paper to obtain global well-posedness results and regularity for several
concrete SPDEs. These include stochastic Navier–Stokes equations, reaction– diffusion
equations and the Allen–Cahn equation. Our setting allows to put these SPDEs into
a more flexible framework, where less restrictions on the nonlinearities are needed,
and we are able to treat rough initial values from critical spaces. Moreover,
we will obtain higher-order regularity results."

text: A domain is called Kac regular for a quadratic form on L2 if every functions
vanishing almost everywhere outside the domain can be approximated in form norm
by functions with compact support in the domain. It is shown that this notion
is stable under domination of quadratic forms. As applications measure perturbations
of quasi-regular Dirichlet forms, Cheeger energies on metric measure spaces and
Schrödinger operators on manifolds are studied. Along the way a characterization
of the Sobolev space with Dirichlet boundary conditions on domains in infinitesimally
Riemannian metric measure spaces is obtained.

text: We study the many-body dynamics of an initially factorized bosonic wave function
in the mean-field regime. We prove large deviation estimates for the fluctuations
around the condensate. We derive an upper bound extending a recent result to more
general interactions. Furthermore, we derive a new lower bound which agrees with
the upper bound in leading order.

text: "Statistics of small subgraph counts such as triangles, four-cycles, and s-t
paths of short lengths reveal important structural properties of the underlying
graph. These problems have been widely studied in social network analysis. In
most relevant applications, the graphs are not only massive but also change dynamically
over time. Most of these problems become hard in the dynamic setting when considering
the worst case. In this paper, we ask whether the question of small subgraph counting
over dynamic graphs is hard also in the average case.\r\n\r\nWe consider the simplest
possible average case model where the updates follow an Erdős-Rényi graph: each
update selects a pair of vertices (u, v) uniformly at random and flips the existence
of the edge (u, v). We develop new lower bounds and matching algorithms in this
model for counting four-cycles, counting triangles through a specified point s,
or a random queried point, and st paths of length 3, 4 and 5. Our results indicate
while computing st paths of length 3, and 4 are easy in the average case with
O(1) update time (note that they are hard in the worst case), it becomes hard
when considering st paths of length 5.\r\n\r\nWe introduce new techniques which
allow us to get average-case hardness for these graph problems from the worst-case
hardness of the Online Matrix vector problem (OMv). Our techniques rely on recent
advances in fine-grained average-case complexity. Our techniques advance this
literature, giving the ability to prove new lower bounds on average-case dynamic
algorithms."

text: We present a practically efficient algorithm for maintaining a global minimum
cut in large dynamic graphs under both edge insertions and deletions. While there
has been theoretical work on this problem, our algorithm is the first implementation
of a fully-dynamic algorithm. The algorithm uses the theoretical foundation and
combines it with efficient and finely-tuned implementations to give an algorithm
that can maintain the global minimum cut of a graph with rapid update times. We
show that our algorithm gives up to multiple orders of magnitude speedup compared
to static approaches both on edge insertions and deletions.

text: A matching is compatible to two or more labeled point sets of size n with
labels {1, . . . , n} if its straight-line drawing on each of these point sets
is crossing-free. We study the maximum number of edges in a matching compatible
to two or more labeled point sets in general position in the plane. We show that
for any two labeled sets of n points in convex position there exists a compatible
matching with ⌊√2n + 1 − 1⌋ edges. More generally, for any ℓ labeled point sets
we construct compatible matchings of size Ω(n1/ℓ). As a corresponding upper bound,
we use probabilistic arguments to show that for any ℓ given sets of n points there
exists a labeling of each set such that the largest compatible matching has O(n2/(ℓ+1))
edges. Finally, we show that Θ(log n) copies of any set of n points are necessary
and sufficient for the existence of labelings of these point sets such that any
compatible matching consists only of a single edge.

text: "G protein-coupled receptors (GPCRs) respond to specific ligands and regulate
multiple processes ranging from cell growth and immune responses to neuronal signal
transmission. However, ligands for many GPCRs remain unknown, suffer from off-target
effects or have poor bioavailability. Additional challenges exist to dissect cell-type
specific responses when the same GPCR is expressed on several cell types within
the body. Here, we overcome these limitations by engineering DREADD-based GPCR
chimeras that selectively bind their agonist clozapine-N-oxide (CNO) and mimic
a GPCR-of-interest in a desired cell type.\r\nWe validated our approach with β2-adrenergic
receptor (β2AR/ADRB2) and show that our chimeric DREADD-β2AR triggers comparable
responses on second messenger and kinase activity, post-translational modifications,
and protein-protein interactions. Since β2AR is also enriched in microglia, which
can drive inflammation in the central nervous system, we expressed chimeric DREADD-β2AR
in primary microglia and successfully recapitulate β2AR-mediated filopodia formation
through CNO stimulation. To dissect the role of selected GPCRs during microglial
inflammation, we additionally generated DREADD-based chimeras for microglia-enriched
GPR65 and GPR109A/HCAR2. In a microglia cell line, DREADD-β2AR and DREADD-GPR65
both modulated the inflammatory response with a similar profile as endogenously
expressed β2AR, while DREADD-GPR109A showed no impact.\r\nOur DREADD-based approach
provides the means to obtain mechanistic and functional insights into GPCR signaling
on a cell-type specific level."

text: The mammalian hippocampal formation (HF) plays a key role in several higher
brain functions, such as spatial coding, learning and memory. Its simple circuit
architecture is often viewed as a trisynaptic loop, processing input originating
from the superficial layers of the entorhinal cortex (EC) and sending it back
to its deeper layers. Here, we show that excitatory neurons in layer 6b of the
mouse EC project to all sub-regions comprising the HF and receive input from the
CA1, thalamus and claustrum. Furthermore, their output is characterized by unique
slow-decaying excitatory postsynaptic currents capable of driving plateau-like
potentials in their postsynaptic targets. Optogenetic inhibition of the EC-6b
pathway affects spatial coding in CA1 pyramidal neurons, while cell ablation impairs
not only acquisition of new spatial memories, but also degradation of previously
acquired ones. Our results provide evidence of a functional role for cortical
layer 6b neurons in the adult brain.

text: Covalent organic frameworks (COFs) are structurally tuneable, porous and crystalline
polymers constructed through the covalent attachment of small organic building
blocks as elementary units. Using the myriad of such building blocks, a broad
spectrum of functionalities has been applied for COF syntheses for broad applications,
including heterogeneous catalysis. Herein, we report the synthesis of a new family
of porous and crystalline COFs using a novel acridine linker and benzene-1,3,5-tricarbaldehyde
derivatives bearing a variable number of hydroxy groups. With the broad absorption
in the visible light region, the COFs were applied as photocatalysts in metallaphotocatalytic
C−N cross-coupling. The fully β-ketoenamine linked COF showed the highest activity,
due to the increased charge separation upon irradiation. The COF showed good to
excellent yields for several aryl bromides, good recyclability and even catalyzed
the organic transformation in presence of green light as energy source.

text: The study of the complexity of the constraint satisfaction problem (CSP),
centred around the Feder-Vardi Dichotomy Conjecture, has been very prominent in
the last two decades. After a long concerted effort and many partial results,
the Dichotomy Conjecture has been proved in 2017 independently by Bulatov and
Zhuk. At about the same time, a vast generalisation of CSP, called promise CSP,
has started to gain prominence. In this survey, we explain the importance of promise
CSP and highlight many new very interesting features that the study of promise
CSP has brought to light. The complexity classification quest for the promise
CSP is wide open, and we argue that, despite the promise CSP being more general,
this quest is rather more accessible to a wide range of researchers than the dichotomy-led
study of the CSP has been.

text: Moulding refers to a set of manufacturing techniques in which a mould, usually
a cavity or a solid frame, is used to shape a liquid or pliable material into
an object of the desired shape. The popularity of moulding comes from its effectiveness,
scalability and versatility in terms of employed materials. Its relevance as a
fabrication process is demonstrated by the extensive literature covering different
aspects related to mould design, from material flow simulation to the automation
of mould geometry design. In this state-of-the-art report, we provide an extensive
review of the automatic methods for the design of moulds, focusing on contributions
from a geometric perspective. We classify existing mould design methods based
on their computational approach and the nature of their target moulding process.
We summarize the relationships between computational approaches and moulding techniques,
highlighting their strengths and limitations. Finally, we discuss potential future
research directions.

text: G protein-coupled receptors (GPCRs) regulate processes ranging from immune
responses to neuronal signaling. However, ligands for many GPCRs remain unknown,
suffer from off-target effects or have poor bioavailability. Additionally, dissecting
cell type-specific responses is challenging when the same GPCR is expressed on
different cells within a tissue. Here, we overcome these limitations by engineering
DREADD-based GPCR chimeras that bind clozapine-N-oxide and mimic a GPCR-of-interest.
We show that chimeric DREADD-β2AR triggers responses comparable to β2AR on second
messenger and kinase activity, post-translational modifications, and protein-protein
interactions. Moreover, we successfully recapitulate β2AR-mediated filopodia formation
in microglia, an immune cell capable of driving central nervous system inflammation.
When dissecting microglial inflammation, we included two additional DREADD-based
chimeras mimicking microglia-enriched GPR65 and GPR109A. DREADD-β2AR and DREADD-GPR65
modulate the inflammatory response with high similarity to endogenous β2AR, while
DREADD-GPR109A shows no impact. Our DREADD-based approach allows investigation
of cell type-dependent pathways without known endogenous ligands.

text: If you mix fruit syrups with alcohol to make a schnapps, the two liquids will
remain perfectly blended forever. But if you mix oil with vinegar to make a vinaigrette,
the oil and vinegar will soon separate back into their previous selves. Such liquid-liquid
phase separation is a thermodynamically driven phenomenon and plays an important
role in many biological processes (1). Although energy injection at the macroscale
can reverse the phase separation—a strong shake is the normal response to a separated
vinaigrette—little is known about the effect of energy added at the microscopic
level on phase separation. This fundamental question has deep ramifications, notably
in biology, because active processes also make the interior of a living cell different
from a dead one. On page 768 of this issue, Adkins et al. (2) examine how mechanical
activity at the microscopic scale affects liquid-liquid phase separation and allows
liquids to climb surfaces.

text: "We study the fate of an impurity in an ultracold heteronuclear Bose mixture,
focusing on the experimentally relevant case of a ⁴¹K - ⁸⁷Rb mixture, with the
impurity in a ⁴¹K hyperfine state. Our paper provides a comprehensive description
of an impurity in a BEC mixture with contact interactions across its phase diagram.
We present results for the miscible and immiscible regimes, as well as for the
impurity in a self-bound quantum droplet. Here, varying the interactions, we find
exotic states where the impurity localizes either at the center or\r\nat the surface
of the droplet. "

text: Recently it became possible to study highly excited rotational states of molecules
in superfluid helium through nonadiabatic alignment experiments (Cherepanov et
al 2021 Phys. Rev. A 104 L061303). This calls for theoretical approaches that
go beyond explaining renormalized values of molecular spectroscopic constants,
which suffices when only the lowest few rotational states are involved. As the
first step in this direction, here we present a basic quantum mechanical model
describing highly excited rotational states of molecules in superfluid helium
nanodroplets. We show that a linear molecule immersed in a superfluid can be seen
as an effective symmetric top, similar to the rotational structure of radicals,
such as OH or NO, but with the angular momentum of the superfluid playing the
role of the electronic angular momentum in free molecules. The simple theory sheds
light onto what happens when the rotational angular momentum of the molecule increases
beyond the lowest excited states accessible by infrared spectroscopy. In addition,
the model allows to estimate the effective rotational and centrifugal distortion
constants for a broad range of species and to explain the crossover between light
and heavy molecules in superfluid 4He in terms of the many-body wavefunction structure.
Some of the above mentioned insights can be acquired by analyzing a simple 2 ×
2 matrix.
