text: High quality graphene heterostructures host an array of fractional quantum
Hall isospin ferromagnets with diverse spin and valley orders. While a variety
of phase transitions have been observed, disentangling the isospin phase diagram
of these states is hampered by the absence of direct probes of spin and valley
order. I will describe nonlocal transport measurements based on launching spin
waves from a gate defined lateral heterojunction, performed in ultra-clean Corbino
geometry graphene devices. At high magnetic fields, we find that the spin-wave
transport signal is detected in all FQH states between ν = 0 and 1; however, between
ν = 1 and 2 only odd numerator FQH states show finite nonlocal transport, despite
the identical ground state spin polarizations in odd- and even numerator states.
The results reveal that the neutral spin-waves are both spin and sublattice polarized
making them a sensitive probe of ground state sublattice structure. Armed with
this understanding, we use nonlocal transport signal to a magnetic field tuned
isospin phase transition, showing that the emergent even denominator state at
ν = 1/2 in monolayer graphene is indeed a multicomponent state featuring equal
populations on each sublattice.

text: We experimentally investigate twisted van der Waals heterostructures of monolayer
graphene rotated with respect to a bernal stacked graphene bilayer. We report
transport measurements for devices with twist angles between 0.9 and 1.4°. The
electric field allows efficient tuning of the width, isolation and the topology
of the moiré bands in this system. By comparing magnetoresistance measurements
to numerical simulations, we develop an understanding of the band structure. Finally,
we observe correlated states at half- and quarter-fillings, which arise when narrow
moire sublattice band is isolated by energy gaps from dispersive bands. We investigate
the effects of in-plane and out-of-plane magnetic field on these states and discuss
the implication for their spin- and valley- polarization.

text: We report the observation of a quantized anomalous Hall effect in a moiré
heterostructure consisting of twisted bilayer graphene aligned to an encapsulating
hBN substrate. The effect occurs at a density of 3 electrons per superlattice
unit cell, where we observe magnetic hysteresis and a Hall resistance quantized
to within 0.1% of the resistance quantum at temperatures as high as 3K. In this
first of 3 talks, I will describe the fabrication procedure for our device as
well as basic transport characterization measurements. I will introduce the phenomenology
of twisted bilayer graphene and present evidence for hBN alignment as manifested
in the hierarchy of symmetry-breaking gaps and anomalous magnetoresistance.

text: This is the second of three talks describing the observation and characterization
of a ferromagnetic moiré heterostructure based on twisted bilayer graphene aligned
to hexagonal boron nitride. I will compare the qualitative and quantitative features
of this observed quantum anomalous Hall state to traditional systems engineered
from thin film (Bi,Sb)2Te3 topological insulators. In particular, we find that
the measured electronic energy gap of ~30K is several times higher than the Curie
temperature, consistent with a lack of disorder associated with magnetic dopants.
In this system, the quantization arises from spontaneous ferromagnetic polarization
into a single spin and valley moiré subband, which is topological despite the
lack of spin orbit coupling. I will also discuss the observation of current induced
switching, which allows the magnetic state of the heterostructure to be controllably
reversed with currents as small as a few nanoamperes.

text: This is the third of three talks describing the observation and characterization
of a ferromagnetic moiré heterostructure based on twisted bilayer graphene aligned
to hexagonal boron nitride. In this segment I will present scanning probe magnetometry
data acquired using a nanoSQUID-on-tip microscope, which provides ~150 nm spatial
resolution and a field sensitivity of ~10 nT/rtHz. We study the distribution of
magnetic domains within the device as a function of density, magnetic field training,
and DC current. Our data allow us to constrain the magnitude of the orbital magnetic
moment of the electrons in the QAH state. Comparison with simultaneously acquired
transport data allows us to precisely correlate single domain dynamics with discrete
jumps in the observed anomalous Hall signal.

text: Partially filled Landau levels host competing electronic orders. For example,
electron solids may prevail close to integer filling of the Landau levels before
giving way to fractional quantum Hall liquids at higher carrier density1,2. Here,
we report the observation of an electron solid with non-collinear spin texture
in monolayer graphene, consistent with solidification of skyrmions3—topological
spin textures characterized by quantized electrical charge4,5. We probe the spin
texture of the solids using a modified Corbino geometry that allows ferromagnetic
magnons to be launched and detected6,7. We find that magnon transport is highly
efficient when one Landau level is filled (ν=1), consistent with quantum Hall
ferromagnetic spin polarization. However, even minimal doping immediately quenches
the magnon signal while leaving the vanishing low-temperature charge conductivity
unchanged. Our results can be understood by the formation of a solid of charged
skyrmions near ν=1, whose non-collinear spin texture leads to rapid magnon decay.
Data near fractional fillings show evidence of several fractional skyrmion solids,
suggesting that graphene hosts a highly tunable landscape of coupled spin and
charge orders.

text: Coxeter triangulations are triangulations of Euclidean space based on a single
simplex. By this we mean that given an individual simplex we can recover the entire
triangulation of Euclidean space by inductively reflecting in the faces of the
simplex. In this paper we establish that the quality of the simplices in all Coxeter
triangulations is O(1/d−−√) of the quality of regular simplex. We further investigate
the Delaunay property for these triangulations. Moreover, we consider an extension
of the Delaunay property, namely protection, which is a measure of non-degeneracy
of a Delaunay triangulation. In particular, one family of Coxeter triangulations
achieves the protection O(1/d2). We conjecture that both bounds are optimal for
triangulations in Euclidean space.

text: 'Genes differ in the frequency at which they are expressed and in the form
of regulation used to control their activity. In particular, positive or negative
regulation can lead to activation of a gene in response to an external signal.
Previous works proposed that the form of regulation of a gene correlates with
its frequency of usage: positive regulation when the gene is frequently expressed
and negative regulation when infrequently expressed. Such network design means
that, in the absence of their regulators, the genes are found in their least required
activity state, hence regulatory intervention is often necessary. Due to the multitude
of genes and regulators, spurious binding and unbinding events, called “crosstalk”,
could occur. To determine how the form of regulation affects the global crosstalk
in the network, we used a mathematical model that includes multiple regulators
and multiple target genes. We found that crosstalk depends non-monotonically on
the availability of regulators. Our analysis showed that excess use of regulation
entailed by the formerly suggested network design caused high crosstalk levels
in a large part of the parameter space. We therefore considered the opposite ‘idle’
design, where the default unregulated state of genes is their frequently required
activity state. We found, that ‘idle’ design minimized the use of regulation and
thus minimized crosstalk. In addition, we estimated global crosstalk of S. cerevisiae
using transcription factors binding data. We demonstrated that even partial network
data could suffice to estimate its global crosstalk, suggesting its applicability
to additional organisms. We found that S. cerevisiae estimated crosstalk is lower
than that of a random network, suggesting that natural selection reduces crosstalk.
In summary, our study highlights a new type of protein production cost which is
typically overlooked: that of regulatory interference caused by the presence of
excess regulators in the cell. It demonstrates the importance of whole-network
descriptions, which could show effects missed by single-gene models.'

text: The relaxation of few-body quantum systems can strongly depend on the initial
state when the system’s semiclassical phase space is mixed; i.e., regions of chaotic
motion coexist with regular islands. In recent years, there has been much effort
to understand the process of thermalization in strongly interacting quantum systems
that often lack an obvious semiclassical limit. The time-dependent variational
principle (TDVP) allows one to systematically derive an effective classical (nonlinear)
dynamical system by projecting unitary many-body dynamics onto a manifold of weakly
entangled variational states. We demonstrate that such dynamical systems generally
possess mixed phase space. When TDVP errors are small, the mixed phase space leaves
a footprint on the exact dynamics of the quantum model. For example, when the
system is initialized in a state belonging to a stable periodic orbit or the surrounding
regular region, it exhibits persistent many-body quantum revivals. As a proof
of principle, we identify new types of “quantum many-body scars,” i.e., initial
states that lead to long-time oscillations in a model of interacting Rydberg atoms
in one and two dimensions. Intriguingly, the initial states that give rise to
most robust revivals are typically entangled states. On the other hand, even when
TDVP errors are large, as in the thermalizing tilted-field Ising model, initializing
the system in a regular region of phase space leads to a surprising slowdown of
thermalization. Our work establishes TDVP as a method for identifying interacting
quantum systems with anomalous dynamics in arbitrary dimensions. Moreover, the
mixed phase space classical variational equations allow one to find slowly thermalizing
initial conditions in interacting models. Our results shed light on a link between
classical and quantum chaos, pointing toward possible extensions of the classical
Kolmogorov-Arnold-Moser theorem to quantum systems.

text: The polymerization–depolymerization dynamics of cytoskeletal proteins play
essential roles in the self-organization of cytoskeletal structures, in eukaryotic
as well as prokaryotic cells. While advances in fluorescence microscopy and in
vitro reconstitution experiments have helped to study the dynamic properties of
these complex systems, methods that allow to collect and analyze large quantitative
datasets of the underlying polymer dynamics are still missing. Here, we present
a novel image analysis workflow to study polymerization dynamics of active filaments
in a nonbiased, highly automated manner. Using treadmilling filaments of the bacterial
tubulin FtsZ as an example, we demonstrate that our method is able to specifically
detect, track and analyze growth and shrinkage of polymers, even in dense networks
of filaments. We believe that this automated method can facilitate the analysis
of a large variety of dynamic cytoskeletal systems, using standard time-lapse
movies obtained from experiments in vitro as well as in the living cell. Moreover,
we provide scripts implementing this method as supplementary material.

text: This paper deals with dynamical optimal transport metrics defined by spatial
discretisation of the Benamou–Benamou formula for the Kantorovich metric . Such
metrics appear naturally in discretisations of -gradient flow formulations for
dissipative PDE. However, it has recently been shown that these metrics do not
in general converge to , unless strong geometric constraints are imposed on the
discrete mesh. In this paper we prove that, in a 1-dimensional periodic setting,
discrete transport metrics converge to a limiting transport metric with a non-trivial
effective mobility. This mobility depends sensitively on the geometry of the mesh
and on the non-local mobility at the discrete level. Our result quantifies to
what extent discrete transport can make use of microstructure in the mesh to reduce
the cost of transport.

text: The eukaryotic endomembrane system is controlled by small GTPases of the Rab
family, which are activated at defined times and locations in a switch-like manner.
While this switch is well understood for an individual protein, how regulatory
networks produce intracellular activity patterns is currently not known. Here,
we combine in vitro reconstitution experiments with computational modeling to
study a minimal Rab5 activation network. We find that the molecular interactions
in this system give rise to a positive feedback and bistable collective switching
of Rab5. Furthermore, we find that switching near the critical point is intrinsically
stochastic and provide evidence that controlling the inactive population of Rab5
on the membrane can shape the network response. Notably, we demonstrate that collective
switching can spread on the membrane surface as a traveling wave of Rab5 activation.
Together, our findings reveal how biochemical signaling networks control vesicle
trafficking pathways and how their nonequilibrium properties define the spatiotemporal
organization of the cell.

text: Small RNAs (smRNA, 19–25 nucleotides long), which are transcribed by RNA polymerase
II, regulate the expression of genes involved in a multitude of processes in eukaryotes.
miRNA biogenesis and the proteins involved in the biogenesis pathway differ across
plant and animal lineages. The major proteins constituting the biogenesis pathway,
namely, the Dicers (DCL/DCR) and Argonautes (AGOs), have been extensively studied.
However, the accessory proteins (DAWDLE (DDL), SERRATE (SE), and TOUGH (TGH))
of the pathway that differs across the two lineages remain largely uncharacterized.
We present the first detailed report on the molecular evolution and divergence
of these proteins across eukaryotes. Although DDL is present in eukaryotes and
prokaryotes, SE and TGH appear to be specific to eukaryotes. The addition/deletion
of specific domains and/or domain-specific sequence divergence in the three proteins
points to the observed functional divergence of these proteins across the two
lineages, which correlates with the differences in miRNA length across the two
lineages. Our data enhance the current understanding of the structure–function
relationship of these proteins and reveals previous unexplored crucial residues
in the three proteins that can be used as a basis for further functional characterization.
The data presented here on the number of miRNAs in crown eukaryotic lineages are
consistent with the notion of the expansion of the number of miRNA-coding genes
in animal and plant lineages correlating with organismal complexity. Whether this
difference in functionally correlates with the diversification (or presence/absence)
of the three proteins studied here or the miRNA signaling in the plant and animal
lineages is unclear. Based on our results of the three proteins studied here and
previously available data concerning the evolution of miRNA genes in the plant
and animal lineages, we believe that miRNAs probably evolved once in the ancestor
to crown eukaryotes and have diversified independently in the eukaryotes.

text: CLC chloride/proton exchangers may support acidification of endolysosomes
and raise their luminal Cl− concentration. Disruption of endosomal ClC‐3 causes
severe neurodegeneration. To assess the importance of ClC‐3 Cl−/H+ exchange, we
now generate Clcn3unc/unc mice in which ClC‐3 is converted into a Cl− channel.
Unlike Clcn3−/− mice, Clcn3unc/unc mice appear normal owing to compensation by
ClC‐4 with which ClC‐3 forms heteromers. ClC‐4 protein levels are strongly reduced
in Clcn3−/−, but not in Clcn3unc/unc mice because ClC‐3unc binds and stabilizes
ClC‐4 like wild‐type ClC‐3. Although mice lacking ClC‐4 appear healthy, its absence
in Clcn3unc/unc/Clcn4−/− mice entails even stronger neurodegeneration than observed
in Clcn3−/− mice. A fraction of ClC‐3 is found on synaptic vesicles, but miniature
postsynaptic currents and synaptic vesicle acidification are not affected in Clcn3unc/unc
or Clcn3−/− mice before neurodegeneration sets in. Both, Cl−/H+‐exchange activity
and the stabilizing effect on ClC‐4, are central to the biological function of
ClC‐3.

text: Heterozygous loss of human PAFAH1B1 (coding for LIS1) results in the disruption
of neurogenesis and neuronal migration via dysregulation of microtubule (MT) stability
and dynein motor function/localization that alters mitotic spindle orientation,
chromosomal segregation, and nuclear migration. Recently, human induced pluripotent
stem cell (iPSC) models revealed an important role for LIS1 in controlling the
length of terminal cell divisions of outer radial glial (oRG) progenitors, suggesting
cellular functions of LIS1 in regulating neural progenitor cell (NPC) daughter
cell separation. Here we examined the late mitotic stages NPCs in vivo and mouse
embryonic fibroblasts (MEFs) in vitro from Pafah1b1-deficient mutants. Pafah1b1-deficient
neocortical NPCs and MEFs similarly exhibited cleavage plane displacement with
mislocalization of furrow-associated markers, associated with actomyosin dysfunction
and cell membrane hyper-contractility. Thus, it suggests LIS1 acts as a key molecular
link connecting MTs/dynein and actomyosin, ensuring that cell membrane contractility
is tightly controlled to execute proper daughter cell separation.

text: The concept of the entanglement between spin and orbital degrees of freedom
plays a crucial role in our understanding of various phases and exotic ground
states in a broad class of materials, including orbitally ordered materials and
spin liquids. We investigate how the spin-orbital entanglement in a Mott insulator
depends on the value of the spin-orbit coupling of the relativistic origin. To
this end, we numerically diagonalize a one-dimensional spin-orbital model with
Kugel-Khomskii exchange interactions between spins and orbitals on different sites
supplemented by the on-site spin-orbit coupling. In the regime of small spin-orbit
coupling with regard to the spin-orbital exchange, the ground state to a large
extent resembles the one obtained in the limit of vanishing spin-orbit coupling.
On the other hand, for large spin-orbit coupling the ground state can, depending
on the model parameters, either still show negligible spin-orbital entanglement
or evolve to a highly spin-orbitally-entangled phase with completely distinct
properties that are described by an effective XXZ model. The presented results
suggest that (i) the spin-orbital entanglement may be induced by large on-site
spin-orbit coupling, as found in the 5d transition metal oxides, such as the iridates;
(ii) for Mott insulators with weak spin-orbit coupling of Ising type, such as,
e.g., the alkali hyperoxides, the effects of the spin-orbit coupling on the ground
state can, in the first order of perturbation theory, be neglected.

text: Directional intercellular transport of the phytohormone auxin mediated by
PIN FORMED (PIN) efflux carriers plays essential roles in both coordinating patterning
processes and integrating multiple external cues by rapidly redirecting auxin
fluxes. Multilevel regulations of PIN activity under internal and external cues
are complicated; however, the underlying molecular mechanism remains elusive.
Here we demonstrate that 3’-Phosphoinositide-Dependent Protein Kinase1 (PDK1),
which is conserved in plants and mammals, functions as a molecular hub integrating
the upstream lipid signalling and the downstream substrate activity through phosphorylation.
Genetic analysis uncovers that loss-of-function Arabidopsis mutant pdk1.1 pdk1.2
exhibits a plethora of abnormalities in organogenesis and growth, due to the defective
PIN-dependent auxin transport. Further cellular and biochemical analyses reveal
that PDK1 phosphorylates D6 Protein Kinase to facilitate its activity towards
PIN proteins. Our studies establish a lipid-dependent phosphorylation cascade
connecting membrane composition-based cellular signalling with plant growth and
patterning by regulating morphogenetic auxin fluxes.

text: Plants are exposed to a variety of abiotic and biotic stresses that may result
in DNA damage. Endogenous processes - such as DNA replication, DNA recombination,
respiration, or photosynthesis - are also a threat to DNA integrity. It is therefore
essential to understand the strategies plants have developed for DNA damage detection,
signaling, and repair. Alternative splicing (AS) is a key post-transcriptional
process with a role in regulation of gene expression. Recent studies demonstrate
that the majority of intron-containing genes in plants are alternatively spliced,
highlighting the importance of AS in plant development and stress response. Not
only does AS ensure a versatile proteome and influence the abundance and availability
of proteins greatly, it has also emerged as an important player in the DNA damage
response (DDR) in animals. Despite extensive studies of DDR carried out in plants,
its regulation at the level of AS has not been comprehensively addressed. Here,
we provide some insights into the interplay between AS and DDR in plants.

text: 'Union-Find (or Disjoint-Set Union) is one of the fundamental problems in
computer science; it has been well-studied from both theoretical and practical
perspectives in the sequential case. Recently, there has been mounting interest
in analyzing this problem in the concurrent scenario, and several asymptotically-efficient
algorithms have been proposed. Yet, to date, there is very little known about
the practical performance of concurrent Union-Find. This work addresses this gap.
We evaluate and analyze the performance of several concurrent Union-Find algorithms
and optimization strategies across a wide range of platforms (Intel, AMD, and
ARM) and workloads (social, random, and road networks, as well as integrations
into more complex algorithms). We first observe that, due to the limited computational
cost, the number of induced cache misses is the critical determining factor for
the performance of existing algorithms. We introduce new techniques to reduce
this cost by storing node priorities implicitly and by using plain reads and writes
in a way that does not affect the correctness of the algorithms. Finally, we show
that Union-Find implementations are an interesting application for Transactional
Memory (TM): one of the fastest algorithm variants we discovered is a sequential
one that uses coarse-grained locking with the lock elision optimization to reduce
synchronization cost and increase scalability. '

text: We consider a system of N bosons in the limit N→∞, interacting through singular
potentials. For initial data exhibiting Bose–Einstein condensation, the many-body
time evolution is well approximated through a quadratic fluctuation dynamics around
a cubic nonlinear Schrödinger equation of the condensate wave function. We show
that these fluctuations satisfy a (multi-variate) central limit theorem.
