text: Neuronal responses to complex stimuli and tasks can encompass a wide range
of time scales. Understanding these responses requires measures that characterize
how the information on these response patterns are represented across multiple
temporal resolutions. In this paper we propose a metric – which we call multiscale
relevance (MSR) – to capture the dynamical variability of the activity of single
neurons across different time scales. The MSR is a non-parametric, fully featureless
indicator in that it uses only the time stamps of the firing activity without
resorting to any a priori covariate or invoking any specific structure in the
tuning curve for neural activity. When applied to neural data from the mEC and
from the ADn and PoS regions of freely-behaving rodents, we found that neurons
having low MSR tend to have low mutual information and low firing sparsity across
the correlates that are believed to be encoded by the region of the brain where
the recordings were made. In addition, neurons with high MSR contain significant
information on spatial navigation and allow to decode spatial position or head
direction as efficiently as those neurons whose firing activity has high mutual
information with the covariate to be decoded and significantly better than the
set of neurons with high local variations in their interspike intervals. Given
these results, we propose that the MSR can be used as a measure to rank and select
neurons for their information content without the need to appeal to any a priori
covariate.

text: Organisms cope with change by employing transcriptional regulators. However,
when faced with rare environments, the evolution of transcriptional regulators
and their promoters may be too slow. We ask whether the intrinsic instability
of gene duplication and amplification provides a generic alternative to canonical
gene regulation. By real-time monitoring of gene copy number mutations in E. coli,
we show that gene duplications and amplifications enable adaptation to fluctuating
environments by rapidly generating copy number, and hence expression level, polymorphism.
This ‘amplification-mediated gene expression tuning’ occurs on timescales similar
to canonical gene regulation and can deal with rapid environmental changes. Mathematical
modeling shows that amplifications also tune gene expression in stochastic environments
where transcription factor-based schemes are hard to evolve or maintain. The fleeting
nature of gene amplifications gives rise to a generic population-level mechanism
that relies on genetic heterogeneity to rapidly tune expression of any gene, without
leaving any genomic signature.

text: Most bacteria accomplish cell division with the help of a dynamic protein
complex called the divisome, which spans the cell envelope in the plane of division.
Assembly and activation of this machinery are coordinated by the tubulin-related
GTPase FtsZ, which was found to form treadmilling filaments on supported bilayers
in vitro1, as well as in live cells, in which filaments circle around the cell
division site2,3. Treadmilling of FtsZ is thought to actively move proteins around
the division septum, thereby distributing peptidoglycan synthesis and coordinating
the inward growth of the septum to form the new poles of the daughter cells4.
However, the molecular mechanisms underlying this function are largely unknown.
Here, to study how FtsZ polymerization dynamics are coupled to downstream proteins,
we reconstituted part of the bacterial cell division machinery using its purified
components FtsZ, FtsA and truncated transmembrane proteins essential for cell
division. We found that the membrane-bound cytosolic peptides of FtsN and FtsQ
co-migrated with treadmilling FtsZ–FtsA filaments, but despite their directed
collective behaviour, individual peptides showed random motion and transient confinement.
Our work suggests that divisome proteins follow treadmilling FtsZ filaments by
a diffusion-and-capture mechanism, which can give rise to a moving zone of signalling
activity at the division site.

text: We give a Wong-Zakai type characterisation of the solutions of quasilinear
heat equations driven by space-time white noise in 1 + 1 dimensions. In order
to show that the renormalisation counterterms are local in the solution, a careful
arrangement of a few hundred terms is required. The main tool in this computation
is a general ‘integration by parts’ formula that provides a number of linear identities
for the renormalisation constants.

text: "Recently Kloeckner described the structure of the isometry group of the quadratic
Wasserstein space W_2(R^n). It turned out that the case of the real line is exceptional
in the sense that there exists an exotic isometry flow. Following this line of
investigation, we compute Isom(W_p(R)), the isometry group of the Wasserstein
space\r\nW_p(R) for all p \\in [1,\\infty) \\setminus {2}. We show that W_2(R)
is also exceptional regarding the\r\nparameter p: W_p(R) is isometrically rigid
if and only if p is not equal to 2. Regarding the underlying\r\nspace, we prove
that the exceptionality of p = 2 disappears if we replace R by the compact\r\ninterval
[0,1]. Surprisingly, in that case, W_p([0,1]) is isometrically rigid if and only
if\r\np is not equal to 1. Moreover, W_1([0,1]) admits isometries that split mass,
and Isom(W_1([0,1]))\r\ncannot be embedded into Isom(W_1(R))."

text: "We study the Gromov waist in the sense of t-neighborhoods for measures in
the Euclidean space, motivated by the famous theorem of Gromov about
\ the waist of radially symmetric Gaussian measures. In particular, it turns
our possible to extend Gromov’s original result to the case of not necessarily
\ radially symmetric Gaussian measure. We also provide examples of measures
having no t-neighborhood waist property, including a rather wide class\r\nof compactly
supported radially symmetric measures and their maps into the Euclidean space
of dimension at least 2.\r\nWe use a simpler form of Gromov’s pancake argument
\ to produce some estimates of t-neighborhoods of (weighted) volume-critical
submanifolds in the spirit of the waist theorems, including neighborhoods of algebraic
manifolds in the complex projective space. In the appendix of this paper we provide
for reader’s convenience a more detailed explanation of the Caffarelli theorem
that we use to handle not necessarily radially symmetric Gaussian\r\nmeasures."

text: 'Epiboly is a conserved gastrulation movement describing the thinning and
spreading of a sheet or multi-layer of cells. The zebrafish embryo has emerged
as a vital model system to address the cellular and molecular mechanisms that
drive epiboly. In the zebrafish embryo, the blastoderm, consisting of a simple
squamous epithelium (the enveloping layer) and an underlying mass of deep cells,
as well as a yolk nuclear syncytium (the yolk syncytial layer) undergo epiboly
to internalize the yolk cell during gastrulation. The major events during zebrafish
epiboly are: expansion of the enveloping layer and the internal yolk syncytial
layer, reduction and removal of the yolk membrane ahead of the advancing blastoderm
margin and deep cell rearrangements between the enveloping layer and yolk syncytial
layer to thin the blastoderm. Here, work addressing the cellular and molecular
mechanisms as well as the sources of the mechanical forces that underlie these
events is reviewed. The contribution of recent findings to the current model of
epiboly as well as open questions and future prospects are also discussed.'

text: Earlier, we demonstrated that transcript levels of METAL TOLERANCE PROTEIN2
(MTP2) and of HEAVY METAL ATPase2 (HMA2) increase strongly in roots of Arabidopsis
upon prolonged zinc (Zn) deficiency and respond to shoot physiological Zn status,
and not to the local Zn status in roots. This provided evidence for shoot-to-root
communication in the acclimation of plants to Zn deficiency. Zn-deficient soils
limit both the yield and quality of agricultural crops and can result in clinically
relevant nutritional Zn deficiency in human populations. Implementing Zn deficiency
during cultivation of the model plant Arabidopsis thaliana on agar-solidified
media is difficult because trace element contaminations are present in almost
all commercially available agars. Here, we demonstrate root morphological acclimations
to Zn deficiency on agar-solidified medium following the effective removal of
contaminants. These advancements allow reproducible phenotyping toward understanding
fundamental plant responses to deficiencies of Zn and other essential trace elements.

text: Previously, we reported that the allelic de-etiolated by zinc (dez) and trichome
birefringence (tbr) mutants exhibit photomorphogenic development in the dark,
which is enhanced by high Zn. TRICHOME BIREFRINGENCE-LIKE proteins had been implicated
in transferring acetyl groups to various hemicelluloses. Pectin O-acetylation
levels were lower in dark-grown dez seedlings than in the wild type. We observed
Zn-enhanced photomorphogenesis in the dark also in the reduced wall acetylation
2 (rwa2-3) mutant, which exhibits lowered O-acetylation levels of cell wall macromolecules
including pectins and xyloglucans, supporting a role for cell wall macromolecule
O-acetylation in the photomorphogenic phenotypes of rwa2-3 and dez. Application
of very short oligogalacturonides (vsOGs) restored skotomorphogenesis in dark-grown
dez and rwa2-3. Here we demonstrate that in dez, O-acetylation of non-pectin cell
wall components, notably of xyloglucan, is enhanced. Our results highlight the
complexity of cell wall homeostasis and indicate against an influence of xyloglucan
O-acetylation on light-dependent seedling development.

text: This paper presents a novel abstraction technique for analyzing Lyapunov and
asymptotic stability of polyhedral switched systems. A polyhedral switched system
is a hybrid system in which the continuous dynamics is specified by polyhedral
differential inclusions, the invariants and guards are specified by polyhedral
sets and the switching between the modes do not involve reset of variables. A
finite state weighted graph abstracting the polyhedral switched system is constructed
from a finite partition of the state–space, such that the satisfaction of certain
graph conditions, such as the absence of cycles with product of weights on the
edges greater than (or equal) to 1, implies the stability of the system. However,
the graph is in general conservative and hence, the violation of the graph conditions
does not imply instability. If the analysis fails to establish stability due to
the conservativeness in the approximation, a counterexample (cycle with product
of edge weights greater than or equal to 1) indicating a potential reason for
the failure is returned. Further, a more precise approximation of the switched
system can be constructed by considering a finer partition of the state–space
in the construction of the finite weighted graph. We present experimental results
on analyzing stability of switched systems using the above method.

text: Plants, like other multicellular organisms, survive through a delicate balance
between growth and defense against pathogens. Salicylic acid (SA) is a major defense
signal in plants, and the perception mechanism as well as downstream signaling
activating the immune response are known. Here, we identify a parallel SA signaling
that mediates growth attenuation. SA directly binds to A subunits of protein phosphatase
2A (PP2A), inhibiting activity of this complex. Among PP2A targets, the PIN2 auxin
transporter is hyperphosphorylated in response to SA, leading to changed activity
of this important growth regulator. Accordingly, auxin transport and auxin-mediated
root development, including growth, gravitropic response, and lateral root organogenesis,
are inhibited. This study reveals how SA, besides activating immunity, concomitantly
attenuates growth through crosstalk with the auxin distribution network. Further
analysis of this dual role of SA and characterization of additional SA-regulated
PP2A targets will provide further insights into mechanisms maintaining a balance
between growth and defense.

text: In the superconducting regime of FeTe(1−x)Sex, there exist two types of vortices
which are distinguished by the presence or absence of zero-energy states in their
core. To understand their origin, we examine the interplay of Zeeman coupling
and superconducting pairings in three-dimensional metals with band inversion.
Weak Zeeman fields are found to suppress intraorbital spin-singlet pairing, known
to localize the states at the ends of the vortices on the surface. On the other
hand, an orbital-triplet pairing is shown to be stable against Zeeman interactions,
but leads to delocalized zero-energy Majorana modes which extend through the vortex.
In contrast, the finite-energy vortex modes remain localized at the vortex ends
even when the pairing is of orbital-triplet form. Phenomenologically, this manifests
as an observed disappearance of zero-bias peaks within the cores of topological
vortices upon an increase of the applied magnetic field. The presence of magnetic
impurities in FeTe(1−x)Sex, which are attracted to the vortices, would lead to
such Zeeman-induced delocalization of Majorana modes in a fraction of vortices
that capture a large enough number of magnetic impurities. Our results provide
an explanation for the dichotomy between topological and nontopological vortices
recently observed in FeTe(1−x)Sex.

text: 'In many real-world systems, information can be transmitted in two qualitatively
different ways: by copying or by transformation. Copying occurs when messages
are transmitted without modification, e.g. when an offspring receives an unaltered
copy of a gene from its parent. Transformation occurs when messages are modified
systematically during transmission, e.g. when mutational biases occur during genetic
replication. Standard information-theoretic measures do not distinguish these
two modes of information transfer, although they may reflect different mechanisms
and have different functional consequences. Starting from a few simple axioms,
we derive a decomposition of mutual information into the information transmitted
by copying versus the information transmitted by transformation. We begin with
a decomposition that applies when the source and destination of the channel have
the same set of messages and a notion of message identity exists. We then generalize
our decomposition to other kinds of channels, which can involve different source
and destination sets and broader notions of similarity. In addition, we show that
copy information can be interpreted as the minimal work needed by a physical copying
process, which is relevant for understanding the physics of replication. We use
the proposed decomposition to explore a model of amino acid substitution rates.
Our results apply to any system in which the fidelity of copying, rather than
simple predictability, is of critical relevance.'

text: "Many methods for the reconstruction of shapes from sets of points produce
ordered simplicial complexes, which are collections of vertices, edges, triangles,
and their higher-dimensional analogues, called simplices, in which every simplex
gets assigned a real value measuring its size. This thesis studies ordered simplicial
complexes, with a focus on their topology, which reflects the connectedness of
the represented shapes and the presence of holes. We are interested both in understanding
better the structure of these complexes, as well as in developing algorithms for
applications.\r\n\r\nFor the Delaunay triangulation, the most popular measure
for a simplex is the radius of the smallest empty circumsphere. Based on it, we
revisit Alpha and Wrap complexes and experimentally determine their probabilistic
properties for random data. Also, we prove the existence of tri-partitions, propose
algorithms to open and close holes, and extend the concepts from Euclidean to
Bregman geometries."

text: 'Retrovirus assembly is driven by the multidomain structural protein Gag.
Interactions between the capsid domains (CA) of Gag result in Gag multimerization,
leading to an immature virus particle that is formed by a protein lattice based
on dimeric, trimeric, and hexameric protein contacts. Among retroviruses the inter-
and intra-hexamer contacts differ, especially in the N-terminal sub-domain of
CA (CANTD). For HIV-1 the cellular molecule inositol hexakisphosphate (IP6) interacts
with and stabilizes the immature hexamer, and is required for production of infectious
virus particles. We have used in vitro assembly, cryo-electron tomography and
subtomogram averaging, atomistic molecular dynamics simulations and mutational
analyses to study the HIV-related lentivirus equine infectious anemia virus (EIAV).
In particular, we sought to understand the structural conservation of the immature
lentivirus lattice and the role of IP6 in EIAV assembly. Similar to HIV-1, IP6
strongly promoted in vitro assembly of EIAV Gag proteins into virus-like particles
(VLPs), which took three morphologically highly distinct forms: narrow tubes,
wide tubes, and spheres. Structural characterization of these VLPs to sub-4Å resolution
unexpectedly showed that all three morphologies are based on an immature lattice
with preserved key structural components, highlighting the structural versatility
of CA to form immature assemblies. A direct comparison between EIAV and HIV revealed
that both lentiviruses maintain similar immature interfaces, which are established
by both conserved and non-conserved residues. In both EIAV and HIV-1, IP6 regulates
immature assembly via conserved lysine residues within the CACTD and SP. Lastly,
we demonstrate that IP6 stimulates in vitro assembly of immature particles of
several other retroviruses in the lentivirus genus, suggesting a conserved role
for IP6 in lentiviral assembly.'

text: The flexible development of plants is characterized by a high capacity for
post-embryonic organ formation and tissue regeneration, processes, which require
tightly regulated intercellular communication and coordinated tissue (re-)polarization.
The phytohormone auxin, the main driver for these processes, is able to establish
polarized auxin transport channels, which are characterized by the expression
and polar, subcellular localization of the PIN1 auxin transport proteins. These
channels are demarcating the position of future vascular strands necessary for
organ formation and tissue regeneration. Major progress has been made in the last
years to understand how PINs can change their polarity in different contexts and
thus guide auxin flow through the plant. However, it still remains elusive how
auxin mediates the establishment of auxin conducting channels and the formation
of vascular tissue and which cellular processes are involved. By the means of
sophisticated regeneration experiments combined with local auxin applications
in Arabidopsis thaliana inflorescence stems we show that (i) PIN subcellular dynamics,
(ii) PIN internalization by clathrin-mediated trafficking and (iii) an intact
actin cytoskeleton required for post-endocytic trafficking are indispensable for
auxin channel formation, de novo vascular formation and vascular regeneration
after wounding. These observations provide novel insights into cellular mechanism
of coordinated tissue polarization during auxin canalization.

text: Unpaired ligands are secreted signals that act via a GP130-like receptor,
domeless, to activate JAK/STAT signalling in Drosophila. Like many mammalian cytokines,
unpaireds can be activated by infection and other stresses and can promote insulin
resistance in target tissues. However, the importance of this effect in non-inflammatory
physiology is unknown. Here, we identify a requirement for unpaired-JAK signalling
as a metabolic regulator in healthy adult Drosophila muscle. Adult muscles show
basal JAK-STAT signalling activity in the absence of any immune challenge. Plasmatocytes
(Drosophila macrophages) are an important source of this tonic signal. Loss of
the dome receptor on adult muscles significantly reduces lifespan and causes local
and systemic metabolic pathology. These pathologies result from hyperactivation
of AKT and consequent deregulation of metabolism. Thus, we identify a cytokine
signal that must be received in muscle to control AKT activity and metabolic homeostasis.

text: Nanomaterials produced from the bottom-up assembly of nanocrystals may incorporate
∼1020–1021 cm–3 not fully coordinated surface atoms, i.e., ∼1020–1021 cm–3 potential
donor or acceptor states that can strongly affect transport properties. Therefore,
to exploit the full potential of nanocrystal building blocks to produce functional
nanomaterials and thin films, a proper control of their surface chemistry is required.
Here, we analyze how the ligand stripping procedure influences the charge and
heat transport properties of sintered PbSe nanomaterials produced from the bottom-up
assembly of colloidal PbSe nanocrystals. First, we show that the removal of the
native organic ligands by thermal decomposition in an inert atmosphere leaves
relatively large amounts of carbon at the crystal interfaces. This carbon blocks
crystal growth during consolidation and at the same time hampers charge and heat
transport through the final nanomaterial. Second, we demonstrate that, by stripping
ligands from the nanocrystal surface before consolidation, nanomaterials with
larger crystal domains, lower porosity, and higher charge carrier concentrations
are obtained, thus resulting in nanomaterials with higher electrical and thermal
conductivities. In addition, the ligand displacement leaves the nanocrystal surface
unprotected, facilitating oxidation and chalcogen evaporation. The influence of
the ligand displacement on the nanomaterial charge transport properties is rationalized
here using a two-band model based on the standard Boltzmann transport equation
with the relaxation time approximation. Finally, we present an application of
the produced functional nanomaterials by modeling, fabricating, and testing a
simple PbSe-based thermoelectric device with a ring geometry.

text: Temporally organized reactivation of experiences during awake immobility periods
is thought to underlie cognitive processes like planning and evaluation. While
replay of trajectories is well established for the hippocampus, it is unclear
whether the medial prefrontal cortex (mPFC) can reactivate sequential behavioral
experiences in the awake state to support task execution. We simultaneously recorded
from hippocampal and mPFC principal neurons in rats performing a mPFC-dependent
rule-switching task on a plus maze. We found that mPFC neuronal activity encoded
relative positions between the start and goal. During awake immobility periods,
the mPFC replayed temporally organized sequences of these generalized positions,
resembling entire spatial trajectories. The occurrence of mPFC trajectory replay
positively correlated with rule-switching performance. However, hippocampal and
mPFC trajectory replay occurred independently, indicating different functions.
These results demonstrate that the mPFC can replay ordered activity patterns representing
generalized locations and suggest that mPFC replay might have a role in flexible
behavior.

text: How structural and functional properties of synapses relate to each other
is a fundamental question in neuroscience. Electrophysiology has elucidated mechanisms
of synaptic transmission, and electron microscopy (EM) has provided insight into
morphological properties of synapses. Here we describe an enhanced method for
functional EM (“flash and freeze”), combining optogenetic stimulation with high-pressure
freezing. We demonstrate that the improved method can be applied to intact networks
in acute brain slices and organotypic slice cultures from mice. As a proof of
concept, we probed vesicle pool changes during synaptic transmission at the hippocampal
mossy fiber-CA3 pyramidal neuron synapse. Our findings show overlap of the docked
vesicle pool and the functionally defined readily releasable pool and provide
evidence of fast endocytosis at this synapse. Functional EM with acute slices
and slice cultures has the potential to reveal the structural and functional mechanisms
of transmission in intact, genetically perturbed, and disease-affected synapses.
