text: Ice cliffs within a supraglacial debris cover have been identified as a source
for high ablation relative to the surrounding debris-covered area. Due to their
small relative size and steep orientation, ice cliffs are difficult to detect
using nadir-looking space borne sensors. The method presented here uses surface
slopes calculated from digital elevation model (DEM) data to map ice cliff geometry
and produce an ice cliff probability map. Surface slope thresholds, which can
be sensitive to geographic location and/or data quality, are selected automatically.
The method also attempts to include area at the (often narrowing) ends of ice
cliffs which could otherwise be neglected due to signal saturation in surface
slope data. The method was calibrated in the eastern Alaska Range, Alaska, USA,
against a control ice cliff dataset derived from high-resolution visible and thermal
data. Using the same input parameter set that performed best in Alaska, the method
was tested against ice cliffs manually mapped in the Khumbu Himal, Nepal. Our
results suggest the method can accommodate different glaciological settings and
different DEM data sources without a data intensive (high-resolution, multi-data
source) recalibration.

text: Supraglacial ice cliffs exist on debris-covered glaciers worldwide, but despite
their importance as melt hot spots, their life cycle is little understood. Early
field observations had advanced a hypothesis of survival of north-facing and disappearance
of south-facing cliffs, which is central for predicting the contribution of cliffs
to total glacier mass losses. Their role as windows of energy transfer suggests
they may explain the anomalously high mass losses of debris-covered glaciers in
High Mountain Asia (HMA) despite the insulating debris, currently at the center
of a debated controversy. We use a 3D model of cliff evolution coupled to very
high-resolution topographic data to demonstrate that ice cliffs facing south (in
the Northern Hemisphere) disappear within a few months due to enhanced solar radiation
receipts and that aspect is the key control on cliffs evolution. We reproduce
continuous flattening of south-facing cliffs, a result of their vertical gradient
of incoming solar radiation and sky view factor. Our results establish that only
north-facing cliffs are recurrent features and thus stable contributors to the
melting of debris-covered glaciers. Satellite observations and mass balance modeling
confirms that few south-facing cliffs of small size exist on the glaciers of Langtang,
and their contribution to the glacier volume losses is very small (∼1%). This
has major implications for the mass balance of HMA debris-covered glaciers as
it provides the basis for new parameterizations of cliff evolution and distribution
to constrain volume losses in a region where glaciers are highly relevant as water
sources for millions of people.

text: We propose a new method for fabricating digital objects through reusable silicone
molds. Molds are generated by casting liquid silicone into custom 3D printed containers
called metamolds. Metamolds automatically define the cuts that are needed to extract
the cast object from the silicone mold. The shape of metamolds is designed through
a novel segmentation technique, which takes into account both geometric and topological
constraints involved in the process of mold casting. Our technique is simple,
does not require changing the shape or topology of the input objects, and only
requires off-the- shelf materials and technologies. We successfully tested our
method on a set of challenging examples with complex shapes and rich geometric
detail. © 2018 Association for Computing Machinery.

genomics, transcriptomics and proteomics to obtain a complete overview of the
evolution of gene dosage on the Z-chromosome of Schistosoma parasites. We compare
the Z-chromosome gene content of African (Schistosoma mansoni and S. haematobium)
and Asian (S. japonicum) schistosomes and describe lineage-specific evolutionary
strata. We use these to assess gene expression evolution following sex-linkage.
The resulting patterns suggest a reduction in expression of Z-linked genes in
females, combined with upregulation of the Z in both sexes, in line with the first
step of Ohno’s classic model of dosage compensation evolution. Quantitative proteomics
suggest that post-transcriptional mechanisms do not play a major role in balancing
the expression of Z-linked genes. '

text: Pancreas development involves a coordinated process in which an early phase
of cell segregation is followed by a longer phase of lineage restriction, expansion,
and tissue remodeling. By combining clonal tracing and whole-mount reconstruction
with proliferation kinetics and single-cell transcriptional profiling, we define
the functional basis of pancreas morphogenesis. We show that the large-scale organization
of mouse pancreas can be traced to the activity of self-renewing precursors positioned
at the termini of growing ducts, which act collectively to drive serial rounds
of stochastic ductal bifurcation balanced by termination. During this phase of
branching morphogenesis, multipotent precursors become progressively fate-restricted,
giving rise to self-renewing acinar-committed precursors that are conveyed with
growing ducts, as well as ductal progenitors that expand the trailing ducts and
give rise to delaminating endocrine cells. These findings define quantitatively
how the functional behavior and lineage progression of precursor pools determine
the large-scale patterning of pancreatic sub-compartments.

text: Focused ion beams perfectly suit for patterning two-dimensional (2D) materials,
but the optimization of irradiation parameters requires full microscopic understanding
of defect production mechanisms. In contrast to freestanding 2D systems, the details
of damage creation in supported 2D materials are not fully understood, whereas
the majority of experiments have been carried out for 2D targets deposited on
substrates. Here, we suggest a universal and computationally efficient scheme
to model the irradiation of supported 2D materials, which combines analytical
potential molecular dynamics with Monte Carlo simulations and makes it possible
to independently assess the contributions to the damage from backscattered ions
and atoms sputtered from the substrate. Using the scheme, we study the defect
production in graphene and MoS2 sheets, which are the two most important and wide-spread
2D materials, deposited on a SiO2 substrate. For helium and neon ions with a wide
range of initial ion energies including those used in a commercial helium ion
microscope (HIM), we demonstrate that depending on the ion energy and mass, the
defect production in 2D systems can be dominated by backscattered ions and sputtered
substrate atoms rather than by the direct ion impacts and that the amount of damage
in 2D materials heavily depends on whether a substrate is present or not. We also
study the factors which limit the spatial resolution of the patterning process.
Our results, which agree well with the available experimental data, provide not
only insights into defect production but also quantitative information, which
can be used for the minimization of damage during imaging in HIM or optimization
of the patterning process.

text: Synchronous programs are easy to specify because the side effects of an operation
are finished by the time the invocation of the operation returns to the caller.
Asynchronous programs, on the other hand, are difficult to specify because there
are side effects due to pending computation scheduled as a result of the invocation
of an operation. They are also difficult to verify because of the large number
of possible interleavings of concurrent computation threads. We present synchronization,
a new proof rule that simplifies the verification of asynchronous programs by
introducing the fiction, for proof purposes, that asynchronous operations complete
synchronously. Synchronization summarizes an asynchronous computation as immediate
atomic effect. Modular verification is enabled via pending asynchronous calls
in atomic summaries, and a complementary proof rule that eliminates pending asynchronous
calls when components and their specifications are composed. We evaluate synchronization
in the context of a multi-layer refinement verification methodology on a collection
of benchmark programs.

text: Parvalbumin-positive (PV+) GABAergic interneurons in hippocampal microcircuits
are thought to play a key role in several higher network functions, such as feedforward
and feedback inhibition, network oscillations, and pattern separation. Fast lateral
inhibition mediated by GABAergic interneurons may implement a winner-takes-all
mechanism in the hippocampal input layer. However, it is not clear whether the
functional connectivity rules of granule cells (GCs) and interneurons in the dentate
gyrus are consistent with such a mechanism. Using simultaneous patch-clamp recordings
from up to seven GCs and up to four PV+ interneurons in the dentate gyrus, we
find that connectivity is structured in space, synapse-specific, and enriched
in specific disynaptic motifs. In contrast to the neocortex, lateral inhibition
in the dentate gyrus (in which a GC inhibits neighboring GCs via a PV+ interneuron)
is ~ 10-times more abundant than recurrent inhibition (in which a GC inhibits
itself). Thus, unique connectivity rules may enable the dentate gyrus to perform
specific higher-order computations

text: The X-ray crystal structures of a decamer sequence d(CGCGTACGCG)2 and a tetradecamer
sequence d(CGCGCGTACGCGCG)2 are presented here. Both sequences are alternating
pyrimidine-purine repeat sequences and they form disordered, pseudo-continuous
left handed Z-type helices. They demonstrate interesting variants of the ‘bundles
of columns of helices’ mode of packing.

text: 'By using a combination of readily accessible experimental and computational
experiments in water, we explored the factors governing the association between
polyanionic dyn[4]arene and a series of α,ω-alkyldiammonium ions of increasing
chain length. We found that the lock-and-key concept based on the best match between
the apolar and polar regions of the molecular partners failed to explain the observed
selectivities. Instead, the dissection of the energetic and structural contributions
demonstrated that the binding events were actually guided by two crucial solvent-related
phenomena as the chain length of the guest increases: the expected decrease of
the enthalpic cost of guest desolvation and the unexpected increase of the favourable
enthalpy of complex solvation. By bringing to light the decisive enthalpic impact
of complex solvation during the binding of polyelectrolytes by inclusion, this
study may provide a missing piece to a puzzle that one day could display the global
picture of molecular recognition in water.'

text: Translation, the mRNA-templated synthesis of peptides by the ribosome, can
be manipulated to incorporate variants of the 20 cognate amino acids. Such approaches
for expanding the range of chemical entities that can be produced by the ribosome
may accelerate the discovery of molecules that can perform functions for which
poorly folded, short peptidic sequences are ill suited. Here, we show that the
ribosome tolerates some artificial helical aromatic oligomers, so-called foldamers.
Using a flexible tRNA-acylation ribozyme—flexizyme—foldamers were attached to
tRNA, and the resulting acylated tRNAs were delivered to the ribosome to initiate
the synthesis of non-cyclic and cyclic foldamer–peptide hybrid molecules. Passing
through the ribosome exit tunnel requires the foldamers to unfold. Yet foldamers
encode sufficient folding information to influence the peptide structure once
translation is completed. We also show that in cyclic hybrids, the foldamer portion
can fold into a helix and force the peptide segment to adopt a constrained and
stretched conformation.

text: 'Phospholipase A2 (PLA2) is one of the rate limiting enzymes involved in the
production of arachidonic acid, a potent inflammatory mediator. PLA2 is widely
distributed all over the animal kingdom. It is also seen in inflammatory exudation
and venoms of different organisms. The studies demonstrated that PLA2 inhibitors
have broad spectrum activities that they can either be used against inflammation
or envenomation. In this study, the inhibitory activity of 1-napthaleneacetic
acid (NAA) against porcine pancreatic PLA2 has been explained through isothermal
titration calorimetry and enzyme kinetics studies. The atomic level of interactions
of NAA with PLA2 was also studied using X-ray crystallography. Apart from these
findings, the theoretical binding affinities and mode of interactions of two naphthalene-based
NSAIDs such as naproxen (NAP) and nabumetone (NAB) were studied through molecular
modeling. The studies proved that the selected ligands are binding at the doorway
of the active site cleft and hindering the substrate entry to the active site.
The study brings out a potential scaffold for the designing of broad spectrum
PLA2 inhibitors which can be used for inflammation or envenomation. '

text: 'In this paper, we report dispersion-engineered metasurfaces with distinct
functionalities controlled by wavelength. Unlike previous approaches based on
spatial multiplexing or vertical stacking of metasurfaces, we utilize a single
phase profile with wavelength dependence encoded in the phase shifters’ dispersion.
We designed and fabricated a multiwavelength achromatic metalens (MAM) with achromatic
focusing for blue (B), green (G), yellow (Y), and red (R) light and two wavelength-controlled
beam generators (WCBG): one focuses light with orbital angular momentum (OAM)
states (l = 0,1,2) corresponding to three primary colors; the other produces ordinary
focal spots (l = 0) for red and green light, while generating a vortex beam (l
= 1) in the blue. A full color (RGB) hologram is also demonstrated in simulation.
Our approach opens a path to applications ranging from near-eye displays and holography
to compact multiwavelength beam generation.'

text: Recent advances in the fabrication of nanostructures and nanoscale features
in metasurfaces offer new prospects for generating visible light emission from
low-energy electrons. Here we present the experimental observation of visible
light emission from low-energy free electrons interacting with nanoscale periodic
surfaces through the Smith–Purcell (SP) effect. We demonstrate SP light emission
from nanoscale gratings with periodicity as small as 50 nm, enabling the observation
of tunable visible radiation from low-energy electrons (1.5 to 6 keV), an order
of magnitude lower in energy than previously reported. We study the emission wavelength
and intensity dependence on the grating pitch and electron energy, showing agreement
between experiment and theory. Our results open the way to the production of SP-based
nanophotonics integrated devices. Built inside electron microscopes, SP sources
could enable the development of novel electron–optical correlated spectroscopic
techniques and facilitate the observation of new quantum effects in light sources.

text: Free-electron radiation such as Cerenkov1, Smith–Purcell2 and transition radiation3,4
can be greatly affected by structured optical environments, as has been demonstrated
in a variety of polaritonic5,6, photonic-crystal7 and metamaterial8,9,10 systems.
However, the amount of radiation that can ultimately be extracted from free electrons
near an arbitrary material structure has remained elusive. Here we derive a fundamental
upper limit to the spontaneous photon emission and energy loss of free electrons,
regardless of geometry, which illuminates the effects of material properties and
electron velocities. We obtain experimental evidence for our theory with quantitative
measurements of Smith–Purcell radiation. Our framework allows us to make two predictions.
One is a new regime of radiation operation—at subwavelength separations, slower
(non-relativistic) electrons can achieve stronger radiation than fast (relativistic)
electrons. The other is a divergence of the emission probability in the limit
of lossless materials. We further reveal that such divergences can be approached
by coupling free electrons to photonic bound states in the continuum11,12,13.
Our findings suggest that compact and efficient free-electron radiation sources
from microwaves to the soft X-ray regime may be achievable without requiring ultrahigh
accelerating voltages.

text: "Quantum electrodynamics (QED) is one of the most precisely tested theories
in the history of science, giving accurate predictions to a wide range of experimental
observations. Recent experimental advances allow for the ability to probe physics
on extremely short attosecond timescales, enabling ultrafast imaging of quantum
dynamics. It is of great interest to extend our understanding of short-time quantum
dynamics to QED, where the focus is typically on long-time observables such as
\U0001D446\r\nmatrices, decay rates, and cross sections. That said, solving the
short-time dynamics of the QED Hamiltonian can lead to divergences, making it
unclear how to arrive at physical predictions. We present an approach to regularize
QED at short times and apply it to the problem of free-electron radiation into
a medium, known as Cherenkov radiation. Our regularization method, which can be
extended to other QED processes, is performed by subtracting the self-energy in
free space from the self-energy calculated in the medium. Surprisingly, we find
a number of previously unknown phenomena yielding corrections to the conventional
Cherenkov effect that could be observed in current experiments. Specifically,
the Cherenkov velocity threshold increases relative to the famous conventional
theory. This modification to the conventional theory, which can be non-negligible
in realistic scenarios, should result in the suppression of spontaneous emission
in readily available experiments. Finally, we reveal a bifurcation process creating
radiation into new Cherenkov angles, occurring in the strong-coupling regime,
which would be realizable by considering the radiation dynamics of highly charged
ions. Our results shed light on QED phenomena at short times and reveal surprising
new physics in the Cherenkov effect."

text: Meta-lenses based on flat optics enabled a fundamental shift in lens production—providing
an easier manufacturing process with an increase in lens profile precision and
a reduction in size and weight. Here we present an analytical approach to correct
spherical aberrations caused by light propagation through the substrate by adding
a substrate-corrected phase profile, which differs from the original hyperbolic
one. A meta-lens encoding the new phase profile would yield diffraction-limited
focusing and an increase of up to 0.3 of its numerical aperture without changing
the radius or focal length. In tightly focused laser spot applications such as
direct laser lithography and laser printing, a substrate-corrected meta-lens can
reduce the spatial footprint of the meta-lens.
