text: Assessment of water resources from remote mountainous catchments plays a crucial
role for the development of rural areas in or in the vicinity of mountain ranges.
The scarcity of data, however, prevents the application of standard approaches
that are based on data-driven models. The Hindu Kush–Karakoram–Himalaya mountain
range is a crucial area in terms of water resources, but our understanding of
the response of its high-elevation catchments to a changing climate is hindered
by lack of hydro-meteorological and cryospheric data. Hydrological modeling is
challenging here because internal inconsistencies—such as an underestimation of
precipitation input that can be compensated for by an overestimation of meltwater—might
be hidden due to the complexity of feedback mechanisms that govern melt and runoff
generation in such basins. Data scarcity adds to this difficulty by preventing
the application of systematic calibration procedures that would allow identification
of the parameter set that could guarantee internal consistency in the simulation
of the single hydrological components. In this work, we use simulations from the
Hunza River Basin in the Karakoram region obtained with the hydrological model
TOPKAPI to quantify the predictive power of discharge and snow-cover data sets,
as well as the combination of both. We also show that short-term measurements
of meteorological variables such as radiative fluxes, wind speed, relative humidity,
and air temperature from glacio-meteorological experiments are crucial for a correct
parameterization of surface melt processes. They enable detailed simulations of
the energy fluxes governing glacier–atmosphere interaction and the resulting ablation
through energy-balance modeling. These simulations are used to derive calibrated
parameters for the simplified snow and glacier routines in TOPKAPI. We demonstrate
that such parameters are stable in space and time in similar climatic regions,
thus reducing the number of parameters requiring calibration.

text: Accurate quantification of the spatial distribution of precipitation in mountain
regions is crucial for assessments of water resources and for the understanding
of high-altitude hydrology, yet it is one of the largest unknowns due to the lack
of high-altitude observations. The Hunza basin in Pakistan contains very large
glacier systems, which, given the melt, cannot persist unless precipitation (snow
input) is much higher than what is observed at the meteorological stations, mostly
located in mountain valleys. Several studies, therefore, suggest strong positive
vertical precipitation lapse rates; in the present study, we quantify this lapse
rate by using glaciers as a proxy. We assume a neutral mass balance for the glaciers
for the period from 2001 to 2003, and we inversely model the precipitation lapse
by balancing the total accumulation in the catchment area and the ablation over
the glacier area for the 50 largest glacier systems in the Hunza basin in the
Karakoram. Our results reveal a vertical precipitation lapse rate that equals
0.21 ± 0.12% m−1, with a maximum precipitation at an elevation of 5500 masl. We
showed that the total annual basin precipitation (828 mm) is 260% higher than
what is estimated based on interpolated observations (319 mm); this has major
consequences for hydrological modeling and water resource assessments in general.
Our results were validated by using previously published studies on individual
glaciers as well as the water balance of the Hunza basin. The approach is more
widely applicable in mountain ranges where precipitation measurements at high
altitude are lacking.

text: Distributed glacier melt models generally assume that the glacier surface
consists of bare exposed ice and snow. In reality, many glaciers are wholly or
partially covered in layers of debris that tend to suppress ablation rates. In
this paper, an existing physically based point model for the ablation of debris-covered
ice is incorporated in a distributed melt model and applied to Haut Glacier d'Arolla,
Switzerland, which has three large patches of debris cover on its surface. The
model is based on a 10 m resolution digital elevation model (DEM) of the area;
each glacier pixel in the DEM is defined as either bare or debris-covered ice,
and may be covered in snow that must be melted off before ice ablation is assumed
to occur. Each debris-covered pixel is assigned a debris thickness value using
probability distributions based on over 1000 manual thickness measurements. Locally
observed meteorological data are used to run energy balance calculations in every
pixel, using an approach suitable for snow, bare ice or debris-covered ice as
appropriate. The use of the debris model significantly reduces the total ablation
in the debris-covered areas, however the precise reduction is sensitive to the
temperature extrapolation used in the model distribution because air near the
debris surface tends to be slightly warmer than over bare ice. Overall results
suggest that the debris patches, which cover 10% of the glacierized area, reduce
total runoff from the glacierized part of the basin by up to 7%.

text: 'Software model checking, as an undecidable problem, has three possible outcomes:
(1) the program satisfies the specification, (2) the program does not satisfy
the specification, and (3) the model checker fails. The third outcome usually
manifests itself in a space-out, time-out, or one component of the verification
tool giving up; in all of these failing cases, significant computation is performed
by the verification tool before the failure, but no result is reported. We propose
to reformulate the model-checking problem as follows, in order to have the verification
tool report a summary of the performed work even in case of failure: given a program
and a specification, the model checker returns a condition Ψ - usually a state
predicate - such that the program satisfies the specification under the condition
Ψ - that is, as long as the program does not leave the states in which Ψ is satisfied.
In our experiments, we investigated as one major application of conditional model
checking the sequential combination of model checkers with information passing.
We give the condition that one model checker produces, as input to a second conditional
model checker, such that the verification problem for the second is restricted
to the part of the state space that is not covered by the condition, i.e., the
second model checker works on the problems that the first model checker could
not solve. Our experiments demonstrate that repeated application of conditional
model checkers, passing information from one model checker to the next, can significantly
improve the verification results and performance, i.e., we can now verify programs
that we could not verify before.'

text: For G = GL 2, PGL 2, SL 2 we prove that the perverse filtration associated
with the Hitchin map on the rational cohomology of the moduli space of twisted
G-Higgs bundles on a compact Riemann surface C agrees with the weight filtration
on the rational cohomology of the twisted G character variety of C when the cohomologies
are identified via non-Abelian Hodge theory. The proof is accomplished by means
of a study of the topology of the Hitchin map over the locus of integral spectral
curves.

text: The spatial organization of cell fates during development involves the interpretation
of morphogen gradients by cellular signaling cascades and transcriptional networks.
Recent studies use biophysical models, genetics, and quantitative imaging to unravel
how tissue-level morphogen behavior arises from subcellular events. Moreover,
data from several systems show that morphogen gradients, downstream signaling,
and the activity of cell-intrinsic transcriptional networks change dynamically
during pattern formation. Studies from Drosophila and now also vertebrates suggest
that transcriptional network dynamics are central to the generation of gene expression
patterns. Together, this leads to the view that pattern formation is an emergent
behavior that results from the coordination of events occurring across molecular,
cellular, and tissue scales. The development of novel approaches to study this
complex process remains a challenge.

text: Self-assembled Ge wires with a height of only 3 unit cells and a length of
up to 2 micrometers were grown on Si(001) by means of a catalyst-free method based
on molecular beam epitaxy. The wires grow horizontally along either the [100]
or the [010] direction. On atomically flat surfaces, they exhibit a highly uniform,
triangular cross section. A simple thermodynamic model accounts for the existence
of a preferential base width for longitudinal expansion, in quantitative agreement
with the experimental findings. Despite the absence of intentional doping, the
first transistor-type devices made from single wires show low-resistive electrical
contacts and single-hole transport at sub-Kelvin temperatures. In view of their
exceptionally small and self-defined cross section, these Ge wires hold promise
for the realization of hole systems with exotic properties and provide a new development
route for silicon-based nanoelectronics.

text: We studied the low-energy states of spin-1/2 quantum dots defined in InAs/InP
nanowires and coupled to aluminum superconducting leads. By varying the superconducting
gap Δ with a magnetic field B we investigated the transition from strong coupling
Δ≪T K to weak-coupling Δ≫T K, where T K is the Kondo temperature. Below the critical
field, we observe a persisting zero-bias Kondo resonance that vanishes only for
low B or higher temperatures, leaving the room to more robust subgap structures
at bias voltages between Δ and 2Δ. For strong and approximately symmetric tunnel
couplings, a Josephson supercurrent is observed in addition to the Kondo peak.
We ascribe the coexistence of a Kondo resonance and a superconducting gap to a
significant density of intragap quasiparticle states, and the finite-bias subgap
structures to tunneling through Shiba states. Our results, supported by numerical
calculations, own relevance also in relation to tunnel-spectroscopy experiments
aiming at the observation of Majorana fermions in hybrid nanostructures.
