text: Hormonal signalling in animals often involves direct transcription factor-hormone
interactions that modulate gene expression. In contrast, plant hormone signalling
is most commonly based on de-repression via the degradation of transcriptional
repressors. Recently, we uncovered a non-canonical signalling mechanism for the
plant hormone auxin whereby auxin directly affects the activity of the atypical
auxin response factor (ARF), ETTIN towards target genes without the requirement
for protein degradation. Here we show that ETTIN directly binds auxin, leading
to dissociation from co-repressor proteins of the TOPLESS/TOPLESS-RELATED family
followed by histone acetylation and induction of gene expression. This mechanism
is reminiscent of animal hormone signalling as it affects the activity towards
regulation of target genes and provides the first example of a DNA-bound hormone
receptor in plants. Whilst auxin affects canonical ARFs indirectly by facilitating
degradation of Aux/IAA repressors, direct ETTIN-auxin interactions allow switching
between repressive and de-repressive chromatin states in an instantly-reversible
manner.

text: "The Massively Parallel Computation (MPC) model is an emerging model which
distills core aspects of distributed and parallel computation. It has been developed
as a tool to solve (typically graph) problems in systems where the input is distributed
over many machines with limited space.\r\n\t\r\nRecent work has focused on the
regime in which machines have sublinear (in $n$, the number of nodes in the input
graph) space, with randomized algorithms presented for fundamental graph problems
of Maximal Matching and Maximal Independent Set. However, there have been no prior
corresponding deterministic algorithms.\r\n\t\r\n\tA major challenge underlying
the sublinear space setting is that the local space of each machine might be too
small to store all the edges incident to a single node. This poses a considerable
obstacle compared to the classical models in which each node is assumed to know
and have easy access to its incident edges. To overcome this barrier we introduce
a new graph sparsification technique that deterministically computes a low-degree
subgraph with additional desired properties. The degree of the nodes in this subgraph
is small in the sense that the edges of each node can be now stored on a single
machine. This low-degree subgraph also has the property that solving the problem
on this subgraph provides \\emph{significant} global progress, i.e., progress
towards solving the problem for the original input graph.\r\n\t\r\nUsing this
framework to derandomize the well-known randomized algorithm of Luby [SICOMP'86],
we obtain $O(\\log \\Delta+\\log\\log n)$-round deterministic MPC algorithms for
solving the fundamental problems of Maximal Matching and Maximal Independent Set
with $O(n^{\\epsilon})$ space on each machine for any constant $\\epsilon > 0$.
Based on the recent work of Ghaffari et al. [FOCS'18], this additive $O(\\log\\log
n)$ factor is conditionally essential. These algorithms can also be shown to run
in $O(\\log \\Delta)$ rounds in the closely related model of CONGESTED CLIQUE,
improving upon the state-of-the-art bound of $O(\\log^2 \\Delta)$ rounds by Censor-Hillel
et al. [DISC'17]."

text: "We settle the complexity of the (Δ+1)-coloring and (Δ+1)-list coloring problems
in the CONGESTED CLIQUE model by presenting a simple deterministic algorithm for
both problems running in a constant number of rounds. This matches the complexity
of the recent breakthrough randomized constant-round (Δ+1)-list coloring algorithm
due to Chang et al. (PODC'19), and significantly improves upon the state-of-the-art
O(logΔ)-round deterministic (Δ+1)-coloring bound of Parter (ICALP'18).\r\nA remarkable
property of our algorithm is its simplicity. Whereas the state-of-the-art randomized
algorithms for this problem are based on the quite involved local coloring algorithm
of Chang et al. (STOC'18), our algorithm can be described in just a few lines.
At a high level, it applies a careful derandomization of a recursive procedure
which partitions the nodes and their respective palettes into separate bins. We
show that after O(1) recursion steps, the remaining uncolored subgraph within
each bin has linear size, and thus can be solved locally by collecting it to a
single node. This algorithm can also be implemented in the Massively Parallel
Computation (MPC) model provided that each machine has linear (in n, the number
of nodes in the input graph) space.\r\nWe also show an extension of our algorithm
to the MPC regime in which machines have sublinear space: we present the first
deterministic (Δ+1)-list coloring algorithm designed for sublinear-space MPC,
which runs in O(logΔ+loglogn) rounds."

text: "We consider the following decision problem EMBEDk→d in computational topology
(where k ≤ d are fixed positive integers): Given a finite simplicial complex K
of dimension k, does there exist a (piecewise-linear) embedding of K into ℝd?\r\nThe
special case EMBED1→2 is graph planarity, which is decidable in linear time, as
shown by Hopcroft and Tarjan. In higher dimensions, EMBED2→3 and EMBED3→3 are
known to be decidable (as well as NP-hard), and recent results of Čadek et al.
in computational homotopy theory, in combination with the classical Haefliger–Weber
theorem in geometric topology, imply that EMBEDk→d can be solved in polynomial
time for any fixed pair (k, d) of dimensions in the so-called metastable range
.\r\nHere, by contrast, we prove that EMBEDk→d is algorithmically undecidable
for almost all pairs of dimensions outside the metastable range, namely for .
This almost completely resolves the decidability vs. undecidability of EMBEDk→d
in higher dimensions and establishes a sharp dichotomy between polynomial-time
solvability and undecidability.\r\nOur result complements (and in a wide range
of dimensions strengthens) earlier results of Matoušek, Tancer, and the second
author, who showed that EMBEDk→d is undecidable for 4 ≤ k ϵ {d – 1, d}, and NP-hard
for all remaining pairs (k, d) outside the metastable range and satisfying d ≥
4."

text: "In a straight-line embedded triangulation of a point set P in the plane,
removing an inner edge and—provided the resulting quadrilateral is convex—adding
the other diagonal is called an edge flip. The (edge) flip graph has all triangulations
as vertices, and a pair of triangulations is adjacent if they can be obtained
from each other by an edge flip. The goal of this paper is to contribute to a
better understanding of the flip graph, with an emphasis on its connectivity.\r\nFor
sets in general position, it is known that every triangulation allows at least
edge flips (a tight bound) which gives the minimum degree of any flip graph for
n points. We show that for every point set P in general position, the flip graph
is at least -vertex connected. Somewhat more strongly, we show that the vertex
connectivity equals the minimum degree occurring in the flip graph, i.e. the minimum
number of flippable edges in any triangulation of P, provided P is large enough.
Finally, we exhibit some of the geometry of the flip graph by showing that the
flip graph can be covered by 1-skeletons of polytopes of dimension (products of
associahedra).\r\nA corresponding result ((n – 3)-vertex connectedness) can be
shown for the bistellar flip graph of partial triangulations, i.e. the set of
all triangulations of subsets of P which contain all extreme points of P. This
will be treated separately in a second part."

text: 'Scientific research is to date largely restricted to wealthy laboratories
in developed nations due to the necessity of complex and expensive equipment.
This inequality limits the capacity of science to be used as a diplomatic channel.
Maker movements use open-source technologies including additive manufacturing
(3D printing) and laser cutting, together with low-cost computers for developing
novel products. This movement is setting the groundwork for a revolution, allowing
scientific equipment to be sourced at a fraction of the cost and has the potential
to increase the availability of equipment for scientists around the world. Science
education is increasingly recognized as another channel for science diplomacy.
In this perspective, we introduce the idea that the Maker movement and open-source
technologies have the potential to revolutionize science, technology, engineering
and mathematics (STEM) education worldwide. We present an open-source STEM didactic
tool called SCOPES (Sparking Curiosity through Open-source Platforms in Education
and Science). SCOPES is self-contained, independent of local resources, and cost-effective.
SCOPES can be adapted to communicate complex subjects from genetics to neurobiology,
perform real-world biological experiments and explore digitized scientific samples.
We envision such platforms will enhance science diplomacy by providing a means
for scientists to share their findings with classrooms and for educators to incorporate
didactic concepts into STEM lessons. By providing students the opportunity to
design, perform, and share scientific experiments, students also experience firsthand
the benefits of a multinational scientific community. We provide instructions
on how to build and use SCOPES on our webpage: http://scopeseducation.org.'

text: 'Water-in-salt electrolytes based on highly concentrated bis(trifluoromethyl)sulfonimide
(TFSI) promise aqueous electrolytes with stabilities nearing 3 V. However, especially
with an electrode approaching the cathodic (reductive) stability, cycling stability
is insufficient. While stability critically relies on a solid electrolyte interphase
(SEI), the mechanism behind the cathodic stability limit remains unclear. Here,
we reveal two distinct reduction potentials for the chemical environments of ''free''
and ''bound'' water and that both contribute to SEI formation. Free-water is reduced
~1V above bound water in a hydrogen evolution reaction (HER) and responsible for
SEI formation via reactive intermediates of the HER; concurrent LiTFSI precipitation/dissolution
establishes a dynamic interface. The free-water population emerges, therefore,
as the handle to extend the cathodic limit of aqueous electrolytes and the battery
cycling stability. '

text: "Purpose of review: Cancer is one of the leading causes of death and the incidence
rates are constantly rising. The heterogeneity of tumors poses a big challenge
for the treatment of the disease and natural antibodies additionally affect disease
progression. The introduction of engineered mAbs for anticancer immunotherapies
has substantially improved progression-free and overall survival of cancer patients,
but little efforts have been made to exploit other antibody isotypes than IgG.\r\nRecent
findings: In order to improve these therapies, ‘next-generation antibodies’ were
engineered to enhance a specific feature of classical antibodies and form a group
of highly effective and precise therapy compounds. Advanced antibody approaches
include among others antibody-drug conjugates, glyco-engineered and Fc-engineered
antibodies, antibody fragments, radioimmunotherapy compounds, bispecific antibodies
and alternative (non-IgG) immunoglobulin classes, especially IgE.\r\nSummary:
The current review describes solutions for the needs of next-generation antibody
therapies through different approaches. Careful selection of the best-suited engineering
methodology is a key factor in developing personalized, more specific and more
efficient mAbs against cancer to improve the outcomes of cancer patients. We highlight
here the large evidence of IgE exploiting a highly cytotoxic effector arm as potential
next-generation anticancer immunotherapy."

text: 'Cells navigating through complex tissues face a fundamental challenge: while
multiple protrusions explore different paths, the cell needs to avoid entanglement.
How a cell surveys and then corrects its own shape is poorly understood. Here,
we demonstrate that spatially distinct microtubule dynamics regulate amoeboid
cell migration by locally promoting the retraction of protrusions. In migrating
dendritic cells, local microtubule depolymerization within protrusions remote
from the microtubule organizing center triggers actomyosin contractility controlled
by RhoA and its exchange factor Lfc. Depletion of Lfc leads to aberrant myosin
localization, thereby causing two effects that rate-limit locomotion: (1) impaired
cell edge coordination during path finding and (2) defective adhesion resolution.
Compromised shape control is particularly hindering in geometrically complex microenvironments,
where it leads to entanglement and ultimately fragmentation of the cell body.
We thus demonstrate that microtubules can act as a proprioceptive device: they
sense cell shape and control actomyosin retraction to sustain cellular coherence.'

text: 'Following its evoked release, dopamine (DA) signaling is rapidly terminated
by presynaptic reuptake, mediated by the cocaine-sensitive DA transporter (DAT).
DAT surface availability is dynamically regulated by endocytic trafficking, and
direct protein kinase C (PKC) activation acutely diminishes DAT surface expression
by accelerating DAT internalization. Previous cell line studies demonstrated that
PKC-stimulated DAT endocytosis requires both Ack1 inactivation, which releases
a DAT-specific endocytic brake, and the neuronal GTPase, Rit2, which binds DAT.
However, it is unknown whether Rit2 is required for PKC-stimulated DAT endocytosis
in DAergic terminals or whether there are region- and/or sex-dependent differences
in PKC-stimulated DAT trafficking. Moreover, the mechanisms by which Rit2 controls
PKC-stimulated DAT endocytosis are unknown. Here, we directly examined these important
questions. Ex vivo studies revealed that PKC activation acutely decreased DAT
surface expression selectively in ventral, but not dorsal, striatum. AAV-mediated,
conditional Rit2 knockdown in DAergic neurons impacted baseline DAT surface:intracellular
distribution in DAergic terminals from female ventral, but not dorsal, striatum.
Further, Rit2 was required for PKC-stimulated DAT internalization in both male
and female ventral striatum. FRET and surface pulldown studies in cell lines revealed
that PKC activation drives DAT-Rit2 surface dissociation and that the DAT N terminus
is required for both PKC-mediated DAT-Rit2 dissociation and DAT internalization.
Finally, we found that Rit2 and Ack1 independently converge on DAT to facilitate
PKC-stimulated DAT endocytosis. Together, our data provide greater insight into
mechanisms that mediate PKC-regulated DAT internalization and reveal unexpected
region-specific differences in PKC-stimulated DAT trafficking in bona fide DAergic
terminals. '

text: Volatile anesthetics are widely used for surgery, but neuronal mechanisms
of anesthesia remain unidentified. At the calyx of Held in brainstem slices from
rats of either sex, isoflurane at clinical doses attenuated EPSCs by decreasing
the release probability and the number of readily releasable vesicles. In presynaptic
recordings of Ca2+ currents and exocytic capacitance changes, isoflurane attenuated
exocytosis by inhibiting Ca2+ currents evoked by a short presynaptic depolarization,
whereas it inhibited exocytosis evoked by a prolonged depolarization via directly
blocking exocytic machinery downstream of Ca2+ influx. Since the length of presynaptic
depolarization can simulate the frequency of synaptic inputs, isoflurane anesthesia
is likely mediated by distinct dual mechanisms, depending on input frequencies.
In simultaneous presynaptic and postsynaptic action potential recordings, isoflurane
impaired the fidelity of repetitive spike transmission, more strongly at higher
frequencies. Furthermore, in the cerebrum of adult mice, isoflurane inhibited
monosynaptic corticocortical spike transmission, preferentially at a higher frequency.
We conclude that dual presynaptic mechanisms operate for the anesthetic action
of isoflurane, of which direct inhibition of exocytic machinery plays a low-pass
filtering role in spike transmission at central excitatory synapses.

text: We explore the time evolution of two impurities in a trapped one-dimensional
Bose gas that follows a change of the boson-impurity interaction. We study the
induced impurity-impurity interactions and their effect on the quench dynamics.
In particular, we report on the size of the impurity cloud, the impurity-impurity
entanglement, and the impurity-impurity correlation function. The presented numerical
simulations are based upon the variational multilayer multiconfiguration time-dependent
Hartree method for bosons. To analyze and quantify induced impurity-impurity correlations,
we employ an effective two-body Hamiltonian with a contact interaction. We show
that the effective model consistent with the mean-field attraction of two heavy
impurities explains qualitatively our results for weak interactions. Our findings
suggest that the quench dynamics in cold-atom systems can be a tool for studying
impurity-impurity correlations.

text: We prove that the Yangian associated to an untwisted symmetric affine Kac–Moody
Lie algebra is isomorphic to the Drinfeld double of a shuffle algebra. The latter
is constructed in [YZ14] as an algebraic formalism of cohomological Hall algebras.
As a consequence, we obtain the Poincare–Birkhoff–Witt (PBW) theorem for this
class of affine Yangians. Another independent proof of the PBW theorem is given
recently by Guay, Regelskis, and Wendlandt [GRW18].

text: An understanding of the missing antinodal electronic excitations in the pseudogap
state is essential for uncovering the physics of the underdoped cuprate high-temperature
superconductors1,2,3,4,5,6. The majority of high-temperature experiments performed
thus far, however, have been unable to discern whether the antinodal states are
rendered unobservable due to their damping or whether they vanish due to their
gapping7,8,9,10,11,12,13,14,15,16,17,18. Here, we distinguish between these two
scenarios by using quantum oscillations to examine whether the small Fermi surface
pocket, found to occupy only 2% of the Brillouin zone in the underdoped cuprates19,20,21,22,23,24,
exists in isolation against a majority of completely gapped density of states
spanning the antinodes, or whether it is thermodynamically coupled to a background
of ungapped antinodal states. We find that quantum oscillations associated with
the small Fermi surface pocket exhibit a signature sawtooth waveform characteristic
of an isolated two-dimensional Fermi surface pocket25,26,27,28,29,30,31,32. This
finding reveals that the antinodal states are destroyed by a hard gap that extends
over the majority of the Brillouin zone, placing strong constraints on a drastic
underlying origin of quasiparticle disappearance over almost the entire Brillouin
zone in the pseudogap regime7,8,9,10,11,12,13,14,15,16,17,18.

text: In agricultural systems, nitrate is the main source of nitrogen available
for plants. Besides its role as a nutrient, nitrate has been shown to act as a
signal molecule for plant growth, development and stress responses. In Arabidopsis,
the NRT1.1 nitrate transceptor represses lateral root (LR) development at low
nitrate availability by promoting auxin basipetal transport out of the LR primordia
(LRPs). In addition, our present study shows that NRT1.1 acts as a negative regulator
of the TAR2 auxin biosynthetic gene expression in the root stele. This is expected
to repress local auxin biosynthesis and thus to reduce acropetal auxin supply
to the LRPs. Moreover, NRT1.1 also negatively affects expression of the LAX3 auxin
influx carrier, thus preventing cell wall remodeling required for overlying tissues
separation during LRP emergence. Both NRT1.1-mediated repression of TAR2 and LAX3
are suppressed at high nitrate availability, resulting in the nitrate induction
of TAR2 and LAX3 expression that is required for optimal stimulation of LR development
by nitrate. Altogether, our results indicate that the NRT1.1 transceptor coordinately
controls several crucial auxin-associated processes required for LRP development,
and as a consequence that NRT1.1 plays a much more integrated role than previously
anticipated in regulating the nitrate response of root system architecture.

text: Peptides derived from non-functional precursors play important roles in various
developmental processes, but also in (a)biotic stress signaling. Our (phospho)proteome-wide
analyses of C-terminally encoded peptide 5 (CEP5)-mediated changes revealed an
impact on abiotic stress-related processes. Drought has a dramatic impact on plant
growth, development and reproduction, and the plant hormone auxin plays a role
in drought responses. Our genetic, physiological, biochemical and pharmacological
results demonstrated that CEP5-mediated signaling is relevant for osmotic and
drought stress tolerance in Arabidopsis, and that CEP5 specifically counteracts
auxin effects. Specifically, we found that CEP5 signaling stabilizes AUX/IAA transcriptional
repressors, suggesting the existence of a novel peptide-dependent control mechanism
that tunes auxin signaling. These observations align with the recently described
role of AUX/IAAs in stress tolerance and provide a novel role for CEP5 in osmotic
and drought stress tolerance.

text: "Isomanifolds are the generalization of isosurfaces to arbitrary dimension
and codimension, i.e. manifolds defined as the zero set of some multivariate vector-valued
smooth function f: ℝ^d → ℝ^(d-n). A natural (and efficient) way to approximate
an isomanifold is to consider its Piecewise-Linear (PL) approximation based on
a triangulation \U0001D4AF of the ambient space ℝ^d. In this paper, we give conditions
under which the PL-approximation of an isomanifold is topologically equivalent
to the isomanifold. The conditions are easy to satisfy in the sense that they
can always be met by taking a sufficiently fine triangulation \U0001D4AF. This
contrasts with previous results on the triangulation of manifolds where, in arbitrary
dimensions, delicate perturbations are needed to guarantee topological correctness,
which leads to strong limitations in practice. We further give a bound on the
Fréchet distance between the original isomanifold and its PL-approximation. Finally
we show analogous results for the PL-approximation of an isomanifold with boundary. "

text: Simple stochastic games are turn-based 2½-player games with a reachability
objective. The basic question asks whether one player can ensure reaching a given
target with at least a given probability. A natural extension is games with a
conjunction of such conditions as objective. Despite a plethora of recent results
on the analysis of systems with multiple objectives, the decidability of this
basic problem remains open. In this paper, we present an algorithm approximating
the Pareto frontier of the achievable values to a given precision. Moreover, it
is an anytime algorithm, meaning it can be stopped at any time returning the current
approximation and its error bound.

text: Let A={A1,…,An} be a family of sets in the plane. For 0≤i2b be integers. We prove that if each k-wise or (k+1)-wise intersection
of sets from A has at most b path-connected components, which all are open, then
fk+1=0 implies fk≤cfk−1 for some positive constant c depending only on b and k.
These results also extend to two-dimensional compact surfaces.
