text: 'Vector Addition Systems with States (VASS) provide a well-known and fundamental
model for the analysis of concurrent processes, parameterized systems, and are
also used as abstract models of programs in resource bound analysis. In this paper
we study the problem of obtaining asymptotic bounds on the termination time of
a given VASS. In particular, we focus on the practically important case of obtaining
polynomial bounds on termination time. Our main contributions are as follows:
First, we present a polynomial-time algorithm for deciding whether a given VASS
has a linear asymptotic complexity. We also show that if the complexity of a VASS
is not linear, it is at least quadratic. Second, we classify VASS according to
quantitative properties of their cycles. We show that certain singularities in
these properties are the key reason for non-polynomial asymptotic complexity of
VASS. In absence of singularities, we show that the asymptotic complexity is always
polynomial and of the form Θ(nk), for some integer k d, where d is the dimension
of the VASS. We present a polynomial-time algorithm computing the optimal k. For
general VASS, the same algorithm, which is based on a complete technique for the
construction of ranking functions in VASS, produces a valid lower bound, i.e.,
a k such that the termination complexity is (nk). Our results are based on new
insights into the geometry of VASS dynamics, which hold the potential for further
applicability to VASS analysis.'

The method introduced here allows genetically encoding the spatial arrangement

text: "A common assumption in causal modeling posits that the data is generated
by a\r\nset of independent mechanisms, and algorithms should aim to recover this\r\nstructure.
Standard unsupervised learning, however, is often concerned with\r\ntraining a
single model to capture the overall distribution or aspects thereof.\r\nInspired
by clustering approaches, we consider mixtures of implicit generative\r\nmodels
that ``disentangle'' the independent generative mechanisms underlying\r\nthe data.
Relying on an additional set of discriminators, we propose a\r\ncompetitive training
procedure in which the models only need to capture the\r\nportion of the data
distribution from which they can produce realistic samples.\r\nAs a by-product,
each model is simpler and faster to train. We empirically show\r\nthat our approach
splits the training distribution in a sensible way and\r\nincreases the quality
of the generated samples."

text: The task of a monitor is to watch, at run-time, the execution of a reactive
system, and signal the occurrence of a safety violation in the observed sequence
of events. While finite-state monitors have been studied extensively, in practice,
monitoring software also makes use of unbounded memory. We define a model of automata
equipped with integer-valued registers which can execute only a bounded number
of instructions between consecutive events, and thus can form the theoretical
basis for the study of infinite-state monitors. We classify these register monitors
according to the number k of available registers, and the type of register instructions.
In stark contrast to the theory of computability for register machines, we prove
that for every k 1, monitors with k + 1 counters (with instruction set 〈+1, =〉)
are strictly more expressive than monitors with k counters. We also show that
adder monitors (with instruction set 〈1, +, =〉) are strictly more expressive than
counter monitors, but are complete for monitoring all computable safety -languages
for k = 6. Real-time monitors are further required to signal the occurrence of
a safety violation as soon as it occurs. The expressiveness hierarchy for counter
monitors carries over to real-time monitors. We then show that 2 adders cannot
simulate 3 counters in real-time. Finally, we show that real-time adder monitors
with inequalities are as expressive as real-time Turing machines.

text: Aged proteins can become hazardous to cellular function, by accumulating molecular
damage. This implies that cells should preferentially rely on newly produced ones.
We tested this hypothesis in cultured hippocampal neurons, focusing on synaptic
transmission. We found that newly synthesized vesicle proteins were incorporated
in the actively recycling pool of vesicles responsible for all neurotransmitter
release during physiological activity. We observed this for the calcium sensor
Synaptotagmin 1, for the neurotransmitter transporter VGAT, and for the fusion
protein VAMP2 (Synaptobrevin 2). Metabolic labeling of proteins and visualization
by secondary ion mass spectrometry enabled us to query the entire protein makeup
of the actively recycling vesicles, which we found to be younger than that of
non-recycling vesicles. The young vesicle proteins remained in use for up to ~
24 h, during which they participated in recycling a few hundred times. They were
afterward reluctant to release and were degraded after an additional ~ 24–48 h.
We suggest that the recycling pool of synaptic vesicles relies on newly synthesized
proteins, while the inactive reserve pool contains older proteins.

text: The root cap protects the stem cell niche of angiosperm roots from damage.
In Arabidopsis, lateral root cap (LRC) cells covering the meristematic zone are
regularly lost through programmed cell death, while the outermost layer of the
root cap covering the tip is repeatedly sloughed. Efficient coordination with
stem cells producing new layers is needed to maintain a constant size of the cap.
We present a signalling pair, the peptide IDA-LIKE1 (IDL1) and its receptor HAESA-LIKE2
(HSL2), mediating such communication. Live imaging over several days characterized
this process from initial fractures in LRC cell files to full separation of a
layer. Enhanced expression of IDL1 in the separating root cap layers resulted
in increased frequency of sloughing, balanced with generation of new layers in
a HSL2-dependent manner. Transcriptome analyses linked IDL1-HSL2 signalling to
the transcription factors BEARSKIN1/2 and genes associated with programmed cell
death. Mutations in either IDL1 or HSL2 slowed down cell division, maturation
and separation. Thus, IDL1-HSL2 signalling potentiates dynamic regulation of the
homeostatic balance between stem cell division and sloughing activity.

text: The trafficking of subcellular cargos in eukaryotic cells crucially depends
on vesicle budding, a process mediated by ARF-GEFs (ADP-ribosylation factor guanine
nucleotide exchange factors). In plants, ARF-GEFs play essential roles in endocytosis,
vacuolar trafficking, recycling, secretion, and polar trafficking. Moreover, they
are important for plant development, mainly through controlling the polar subcellular
localization of PIN-FORMED (PIN) transporters of the plant hormone auxin. Here,
using a chemical genetics screen in Arabidopsis thaliana, we identified Endosidin
4 (ES4), an inhibitor of eukaryotic ARF-GEFs. ES4 acts similarly to and synergistically
with the established ARF-GEF inhibitor Brefeldin A and has broad effects on intracellular
trafficking, including endocytosis, exocytosis, and vacuolar targeting. Additionally,
Arabidopsis and yeast (Sacharomyces cerevisiae) mutants defective in ARF-GEF show
altered sensitivity to ES4. ES4 interferes with the activation-based membrane
association of the ARF1 GTPases, but not of their mutant variants that are activated
independently of ARF-GEF activity. Biochemical approaches and docking simulations
confirmed that ES4 specifically targets the SEC7 domain-containing ARF-GEFs. These
observations collectively identify ES4 as a chemical tool enabling the study of
ARF-GEF-mediated processes, including ARF-GEF-mediated plant development.

text: 'Land plants evolved from charophytic algae, among which Charophyceae possess
the most complex body plans. We present the genome of Chara braunii; comparison
of the genome to those of land plants identified evolutionary novelties for plant
terrestrialization and land plant heritage genes. C. braunii employs unique xylan
synthases for cell wall biosynthesis, a phragmoplast (cell separation) mechanism
similar to that of land plants, and many phytohormones. C. braunii plastids are
controlled via land-plant-like retrograde signaling, and transcriptional regulation
is more elaborate than in other algae. The morphological complexity of this organism
may result from expanded gene families, with three cases of particular note: genes
effecting tolerance to reactive oxygen species (ROS), LysM receptor-like kinases,
and transcription factors (TFs). Transcriptomic analysis of sexual reproductive
structures reveals intricate control by TFs, activity of the ROS gene network,
and the ancestral use of plant-like storage and stress protection proteins in
the zygote.'

text: A short, 14-amino-acid segment called SP1, located in the Gag structural protein1,
has a critical role during the formation of the HIV-1 virus particle. During virus
assembly, the SP1 peptide and seven preceding residues fold into a six-helix bundle,
which holds together the Gag hexamer and facilitates the formation of a curved
immature hexagonal lattice underneath the viral membrane2,3. Upon completion of
assembly and budding, proteolytic cleavage of Gag leads to virus maturation, in
which the immature lattice is broken down; the liberated CA domain of Gag then
re-assembles into the mature conical capsid that encloses the viral genome and
associated enzymes. Folding and proteolysis of the six-helix bundle are crucial
rate-limiting steps of both Gag assembly and disassembly, and the six-helix bundle
is an established target of HIV-1 inhibitors4,5. Here, using a combination of
structural and functional analyses, we show that inositol hexakisphosphate (InsP6,
also known as IP6) facilitates the formation of the six-helix bundle and assembly
of the immature HIV-1 Gag lattice. IP6 makes ionic contacts with two rings of
lysine residues at the centre of the Gag hexamer. Proteolytic cleavage then unmasks
an alternative binding site, where IP6 interaction promotes the assembly of the
mature capsid lattice. These studies identify IP6 as a naturally occurring small
molecule that promotes both assembly and maturation of HIV-1.

text: To maintain genome integrity, segmented double-stranded RNA viruses of the
Reoviridae family must accurately select and package a complete set of up to a
dozen distinct genomic RNAs. It is thought that the high fidelity segmented genome
assembly involves multiple sequence-specific RNA–RNA interactions between single-stranded
RNA segment precursors. These are mediated by virus-encoded non-structural proteins
with RNA chaperone-like activities, such as rotavirus (RV) NSP2 and avian reovirus
σNS. Here, we compared the abilities of NSP2 and σNS to mediate sequence-specific
interactions between RV genomic segment precursors. Despite their similar activities,
NSP2 successfully promotes inter-segment association, while σNS fails to do so.
To understand the mechanisms underlying such selectivity in promoting inter-molecular
duplex formation, we compared RNA-binding and helix-unwinding activities of both
proteins. We demonstrate that octameric NSP2 binds structured RNAs with high affinity,
resulting in efficient intramolecular RNA helix disruption. Hexameric σNS oligomerizes
into an octamer that binds two RNAs, yet it exhibits only limited RNA-unwinding
activity compared to NSP2. Thus, the formation of intersegment RNA–RNA interactions
is governed by both helix-unwinding capacity of the chaperones and stability of
RNA structure. We propose that this protein-mediated RNA selection mechanism may
underpin the high fidelity assembly of multi-segmented RNA genomes in Reoviridae.

text: Complex I has an essential role in ATP production by coupling electron transfer
from NADH to quinone with translocation of protons across the inner mitochondrial
membrane. Isolated complex I deficiency is a frequent cause of mitochondrial inherited
diseases. Complex I has also been implicated in cancer, ageing, and neurodegenerative
conditions. Until recently, the understanding of complex I deficiency on the molecular
level was limited due to the lack of high-resolution structures of the enzyme.
However, due to developments in single particle cryo-electron microscopy (cryo-EM),
recent studies have reported nearly atomic resolution maps and models of mitochondrial
complex I. These structures significantly add to our understanding of complex
I mechanism and assembly. The disease-causing mutations are discussed here in
their structural context.

text: 'In this paper we describe the potential of the enhanced X-ray Timing and
Polarimetry (eXTP) mission for studies related to accretion flows in the strong
field gravity regime around both stellar-mass and supermassive black-holes. eXTP
has the unique capability of using advanced “spectral-timing-polarimetry” techniques
to analyze the rapid variations with three orthogonal diagnostics of the flow
and its geometry, yielding unprecedented insight into the inner accreting regions,
the effects of strong field gravity on the material within them and the powerful
outflows which are driven by the accretion process. '

text: In this paper we present the science potential of the enhanced X-ray Timing
and Polarimetry (eXTP) mission for studies of strongly magnetized objects. We
will focus on the physics and astrophysics of strongly magnetized objects, namely
magnetars, accreting X-ray pulsars, and rotation powered pulsars. We also discuss
the science potential of eXTP for QED studies. Developed by an international Consortium
led by the Institute of High Energy Physics of the Chinese Academy of Sciences,
the eXTP mission is expected to be launched in the mid 2020s.

text: Using parallaxes from Gaia Data Release 2 (Gaia DR2), we estimate the distance
to the globular clusters 47 Tuc and NGC 362, taking advantage of the background
stars in the Small Magellanic Cloud and quasars to account for various parallax
systematics. We found the parallax to be dependent on the Gaia DR2 G-band apparent
magnitude for stars with 13 < G < 18, where brighter stars have a lower parallax
zero point than fainter stars. The distance to 47 Tuc was found to be 4.45 ± 0.01
± 0.12 kpc, and for NGC 362 8.54 ± 0.20 ± 0.44 kpc, with random and systematic
errors listed, respectively. This is the first time a precise distance measurement
directly using parallaxes has been determined for either of these two globular
clusters.

text: Radiative corrections of quantum electrodynamics cause a vacuum threaded by
a magnetic field to be birefringent. This means that radiation of different polarizations
travels at different speeds. Even in the strong magnetic fields of astrophysical
sources, the difference in speed is small. However, it has profound consequences
for the extent of polarization expected from strongly magnetized sources. We demonstrate
how the birefringence arises from first principles, show how birefringence affects
the polarization state of radiation and present recent calculations for the expected
polarization from magnetars and X-ray pulsars.

text: 'Radio pulsars found in binary systems with short orbital periods are usually
fast spinning as a consequence of recycling via mass transfer from their companion
stars; this process is also thought to decrease the magnetic field of the neutron
star being recycled. Here, we report on timing observations of the recently discovered
binary PSR J1755−2550 and find that this pulsar is an exception: with a characteristic
age of 2.1 Myr, it is relatively young; furthermore, with a spin period of 315 ms
and a surface magnetic field strength at its poles of 0.88 × 1012 G, the pulsar
shows no sign of having been recycled. Based on its timing and orbital characteristics,
the pulsar either has a massive white dwarf (WD) or a neutron star (NS) companion.
To distinguish between these two cases, we searched radio observations for a potential
recycled pulsar companion and analysed archival optical data for a potential WD
companion. Neither work returned conclusive detections. We apply population synthesis
modelling and find that both solutions are roughly equally probable. Our population
synthesis also predicts a minimum mass of 0.90 M⊙ for the companion star to PSR
J1755−2550 and we simulate the systemic runaway velocities for the resulting WDNS
systems which may merge and possibly produce Ca-rich supernovae. Whether PSR J1755−2550
hosts a WD or a NS companion star, it is certainly a member of a rare subpopulation
of binary radio pulsars.'

text: 'The effect of vacuum birefringence is one of the first predictions of quantum
electrodynamics (QED): the presence of a charged Dirac field makes the vacuum
birefringent when threaded by magnetic fields. This effect, extremely weak for
terrestrial magnetic fields, becomes important for highly magnetized astrophysical
objects, such as accreting black holes. In the X-ray regime, the polarization
of photons traveling in the magnetosphere of a black hole is not frozen at emission
but is changed by the local magnetic field. We show that, for photons traveling
along the plane of the disk, where the field is expected to be partially organized,
this results in a depolarization of the X-ray radiation. Because the amount of
depolarization depends on the strength of the magnetic field, this effect can
provide a way to probe the magnetic field in black-hole accretion disks and to
study the role of magnetic fields in astrophysical accretion in general.'

text: 'In the next decade, x-ray polarimetry will open a new window on the high-energy
Universe, as several missions that include an x-ray polarimeter are currently
under development. Observations of the polarization of x rays coming from the
accretion disks of stellar-mass and supermassive black holes are among the new
polarimeters’ major objectives. In this paper, we show that these observations
can be affected by the quantum electrodynamic (QED) effect of vacuum birefringence:
after an x-ray photon is emitted from the accretion disk, its polarization changes
as the photon travels through the accretion disk’s magnetosphere, as a result
of the vacuum becoming birefringent in the presence of a magnetic field. We show
that this effect can be important for black holes in the energy band of the upcoming
polarimeters and has to be taken into account in a complete model of the x-ray
polarization that we expect to detect from black-hole accretion disks, both for
stellar mass and for supermassive black holes. We find that, for a chaotic magnetic
field in the disk, QED can significantly decrease the linear polarization fraction
of edge-on photons, depending on the spin of the hole and on the strength of the
magnetic field. This effect can provide, for the first time, a direct way to probe
the magnetic field strength close to the innermost stable orbit of black-hole
accretion disks and to study the role of magnetic fields in astrophysical accretion
in general.'

text: Cells migrating in multicellular organisms steadily traverse complex three-dimensional
(3D) environments. To decipher the underlying cell biology, current experimental
setups either use simplified 2D, tissue-mimetic 3D (e.g., collagen matrices) or
in vivo environments. While only in vivo experiments are truly physiological,
they do not allow for precise manipulation of environmental parameters. 2D in
vitro experiments do allow mechanical and chemical manipulations, but increasing
evidence demonstrates substantial differences of migratory mechanisms in 2D and
3D. Here, we describe simple, robust, and versatile “pillar forests” to investigate
cell migration in complex but fully controllable 3D environments. Pillar forests
are polydimethylsiloxane-based setups, in which two closely adjacent surfaces
are interconnected by arrays of micrometer-sized pillars. Changing the pillar
shape, size, height and the inter-pillar distance precisely manipulates microenvironmental
parameters (e.g., pore sizes, micro-geometry, micro-topology), while being easily
combined with chemotactic cues, surface coatings, diverse cell types and advanced
imaging techniques. Thus, pillar forests combine the advantages of 2D cell migration
assays with the precise definition of 3D environmental parameters.
