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.

text: 'A string graph is the intersection graph of a family of continuous arcs in
the plane. The intersection graph of a family of plane convex sets is a string
graph, but not all string graphs can be obtained in this way. We prove the following
structure theorem conjectured by Janson and Uzzell: The vertex set of almost all
string graphs on n vertices can be partitioned into five cliques such that some
pair of them is not connected by any edge (n→∞). We also show that every graph
with the above property is an intersection graph of plane convex sets. As a corollary,
we obtain that almost all string graphs on n vertices are intersection graphs

text: Organic materials are known to feature long spin-diffusion times, originating
in a generally small spin–orbit coupling observed in these systems. From that
perspective, chiral molecules acting as efficient spin selectors pose a puzzle
that attracted a lot of attention in recent years. Here, we revisit the physical
origins of chiral-induced spin selectivity (CISS) and propose a simple analytic
minimal model to describe it. The model treats a chiral molecule as an anisotropic
wire with molecular dipole moments aligned arbitrarily with respect to the wire’s
axes and is therefore quite general. Importantly, it shows that the helical structure
of the molecule is not necessary to observe CISS and other chiral nonhelical molecules
can also be considered as potential candidates for the CISS effect. We also show
that the suggested simple model captures the main characteristics of CISS observed
in the experiment, without the need for additional constraints employed in the
previous studies. The results pave the way for understanding other related physical
phenomena where the CISS effect plays an essential role.

text: Multilayer graphene lattices allow for an additional tunability of the band
structure by the strong perpendicular electric field. In particular, the emergence
of the new multiple Dirac points in ABA stacked trilayer graphene subject to strong
transverse electric fields was proposed theoretically and confirmed experimentally.
These new Dirac points dubbed “gullies” emerge from the interplay between strong
electric field and trigonal warping. In this work, we first characterize the properties
of new emergent Dirac points and show that the electric field can be used to tune
the distance between gullies in the momentum space. We demonstrate that the band
structure has multiple Lifshitz transitions and higher-order singularity of “monkey
saddle” type. Following the characterization of the band structure, we consider
the spectrum of Landau levels and structure of their wave functions. In the limit
of strong electric fields when gullies are well separated in momentum space, they
give rise to triply degenerate Landau levels. In the second part of this work,
we investigate how degeneracy between three gully Landau levels is lifted in the
presence of interactions. Within the Hartree-Fock approximation we show that the
symmetry breaking state interpolates between the fully gully polarized state that
breaks C3 symmetry at high displacement field and the gully symmetric state when
the electric field is decreased. The discontinuous transition between these two
states is driven by enhanced intergully tunneling and exchange. We conclude by
outlining specific experimental predictions for the existence of such a symmetry-breaking
state.

text: The goal of limiting global warming to 1.5 °C requires a drastic reduction
in CO2 emissions across many sectors of the world economy. Batteries are vital
to this endeavor, whether used in electric vehicles, to store renewable electricity,
or in aviation. Present lithium-ion technologies are preparing the public for
this inevitable change, but their maximum theoretical specific capacity presents
a limitation. Their high cost is another concern for commercial viability. Metal–air
batteries have the highest theoretical energy density of all possible secondary
battery technologies and could yield step changes in energy storage, if their
practical difficulties could be overcome. The scope of this review is to provide
an objective, comprehensive, and authoritative assessment of the intensive work
invested in nonaqueous rechargeable metal–air batteries over the past few years,
which identified the key problems and guides directions to solve them. We focus
primarily on the challenges and outlook for Li–O2 cells but include Na–O2, K–O2,
and Mg–O2 cells for comparison. Our review highlights the interdisciplinary nature
of this field that involves a combination of materials chemistry, electrochemistry,
computation, microscopy, spectroscopy, and surface science. The mechanisms of
O2 reduction and evolution are considered in the light of recent findings, along
with developments in positive and negative electrodes, electrolytes, electrocatalysis
on surfaces and in solution, and the degradative effect of singlet oxygen, which
is typically formed in Li–O2 cells.

text: 'We prove general topological Radon-type theorems for sets in ℝ^d, smooth
real manifolds or finite dimensional simplicial complexes. Combined with a recent
result of Holmsen and Lee, it gives fractional Helly theorem, and consequently
the existence of weak ε-nets as well as a (p,q)-theorem. More precisely: Let X
be either ℝ^d, smooth real d-manifold, or a finite d-dimensional simplicial complex.
Then if F is a finite, intersection-closed family of sets in X such that the ith
reduced Betti number (with ℤ₂ coefficients) of any set in F is at most b for every
non-negative integer i less or equal to k, then the Radon number of F is bounded
in terms of b and X. Here k is the smallest integer larger or equal to d/2 - 1
if X = ℝ^d; k=d-1 if X is a smooth real d-manifold and not a surface, k=0 if X
is a surface and k=d if X is a d-dimensional simplicial complex. Using the recent
result of the author and Kalai, we manage to prove the following optimal bound
on fractional Helly number for families of open sets in a surface: Let F be a
finite family of open sets in a surface S such that the intersection of any subfamily
of F is either empty, or path-connected. Then the fractional Helly number of F
is at most three. This also settles a conjecture of Holmsen, Kim, and Lee about
an existence of a (p,q)-theorem for open subsets of a surface.'

text: 'Given a finite point set P in general position in the plane, a full triangulation
is a maximal straight-line embedded plane graph on P. A partial triangulation
on P is a full triangulation of some subset P'' of P containing all extreme points
in P. A bistellar flip on a partial triangulation either flips an edge, removes
a non-extreme point of degree 3, or adds a point in P ⧵ P'' as vertex of degree
3. The bistellar flip graph has all partial triangulations as vertices, and a
pair of partial triangulations is adjacent if they can be obtained from one another
by a bistellar flip. The goal of this paper is to investigate the structure of
this graph, with emphasis on its connectivity. For sets P of n points in general
position, we show that the bistellar flip graph is (n-3)-connected, thereby answering,
for sets in general position, an open questions raised in a book (by De Loera,
Rambau, and Santos) and a survey (by Lee and Santos) on triangulations. This matches
the situation for the subfamily of regular triangulations (i.e., partial triangulations
obtained by lifting the points and projecting the lower convex hull), where (n-3)-connectivity
has been known since the late 1980s through the secondary polytope (Gelfand, Kapranov,
Zelevinsky) and Balinski’s Theorem. Our methods also yield the following results
(see the full version [Wagner and Welzl, 2020]): (i) The bistellar flip graph
can be covered by graphs of polytopes of dimension n-3 (products of secondary
polytopes). (ii) A partial triangulation is regular, if it has distance n-3 in
the Hasse diagram of the partial order of partial subdivisions from the trivial
subdivision. (iii) All partial triangulations are regular iff the trivial subdivision
has height n-3 in the partial order of partial subdivisions. (iv) There are arbitrarily
large sets P with non-regular partial triangulations, while every proper subset
has only regular triangulations, i.e., there are no small certificates for the
existence of non-regular partial triangulations (answering a question by F. Santos
in the unexpected direction).'

text: 'We define and study a discrete process that generalizes the convex-layer
decomposition of a planar point set. Our process, which we call homotopic curve
shortening (HCS), starts with a closed curve (which might self-intersect) in the
presence of a set P⊂ ℝ² of point obstacles, and evolves in discrete steps, where
each step consists of (1) taking shortcuts around the obstacles, and (2) reducing
the curve to its shortest homotopic equivalent. We find experimentally that, if
the initial curve is held fixed and P is chosen to be either a very fine regular
grid or a uniformly random point set, then HCS behaves at the limit like the affine
curve-shortening flow (ACSF). This connection between HCS and ACSF generalizes
the link between "grid peeling" and the ACSF observed by Eppstein et al. (2017),
which applied only to convex curves, and which was studied only for regular grids.
We prove that HCS satisfies some properties analogous to those of ACSF: HCS is
invariant under affine transformations, preserves convexity, and does not increase
the total absolute curvature. Furthermore, the number of self-intersections of
a curve, or intersections between two curves (appropriately defined), does not
increase. Finally, if the initial curve is simple, then the number of inflection
points (appropriately defined) does not increase.'

text: 'Let K be a convex body in ℝⁿ (i.e., a compact convex set with nonempty interior).
Given a point p in the interior of K, a hyperplane h passing through p is called
barycentric if p is the barycenter of K ∩ h. In 1961, Grünbaum raised the question
whether, for every K, there exists an interior point p through which there are
at least n+1 distinct barycentric hyperplanes. Two years later, this was seemingly
resolved affirmatively by showing that this is the case if p=p₀ is the point of
maximal depth in K. However, while working on a related question, we noticed that
one of the auxiliary claims in the proof is incorrect. Here, we provide a counterexample;
this re-opens Grünbaum’s question. It follows from known results that for n ≥
2, there are always at least three distinct barycentric cuts through the point
p₀ ∈ K of maximal depth. Using tools related to Morse theory we are able to improve
this bound: four distinct barycentric cuts through p₀ are guaranteed if n ≥ 3.'
