text: Hydrologic and geomorphic responses of watersheds to changes in climate are
difficult to assess due to projection uncertainties and nonlinearity of the processes
that are involved. Yet such assessments are increasingly needed and call for mechanistic
approaches within a probabilistic framework. This study employs an integrated
hydrology‐geomorphology model, the Triangulated Irregular Network‐based Real‐time
Integrated Basin Simulator (tRIBS)‐Erosion, to analyze runoff and erosion sensitivity
of seven semiarid headwater basins to projected climate conditions. The Advanced
Weather Generator is used to produce two climate ensembles representative of the
historic and future climate conditions for the Walnut Gulch Experimental Watershed
located in the southwest U.S. The former ensemble incorporates the stochastic
variability of the observed climate, while the latter includes the stochastic
variability and the uncertainty of multimodel climate change projections. The
ensembles are used as forcing for tRIBS‐Erosion that simulates runoff and sediment
basin responses leading to probabilistic inferences of future changes. The results
show that annual precipitation for the area is generally expected to decrease
in the future, with lower hourly intensities and similar daily rates. The smaller
hourly rainfall generally results in lower mean annual runoff. However, a non‐negligible
probability of runoff increase in the future is identified, resulting from stochastic
combinations of years with low and high runoff. On average, the magnitudes of
mean and extreme events of sediment yield are expected to decrease with a very
high probability. Importantly, the projected variability of annual sediment transport
for the future conditions is comparable to that for the historic conditions, despite
the fact that the former account for a much wider range of possible climate “alternatives.”
This result demonstrates that the historic natural climate variability of sediment
yield is already so high, that it is comparable to the variability for a projected
and highly uncertain future. Additionally, changes in the scaling relationship
between specific sediment yield/runoff and drainage basin area are detected.

text: Extreme rainfall events are the major driver of shallow landslide occurrences
in mountainous and steep terrain regions around the world. Subsurface hydrology
has a dominant role on the initiation of rainfall-induced shallow landslides,
since changes in the soil water content affect significantly the soil shear strength.
Rainfall infiltration produces an increase of soil water potential, which is followed
by a rapid drop in apparent cohesion. Especially on steep slopes of shallow soils,
this loss of shear strength can lead to failure even in unsaturated conditions
before positive water pressures are developed. We present HYDROlisthisis, a process-based
model, fully distributed in space with fine time resolution, in order to investigate
the interactions between surface and subsurface hydrology and shallow landslides
initiation. Fundamental elements of the approach are the dependence of shear strength
on the three-dimensional (3-D) field of soil water potential, as well as the temporal
evolution of soil water potential during the wetting and drying phases. Specifically,
3-D variably saturated flow conditions, including soil hydraulic hysteresis and
preferential flow phenomena, are simulated for the subsurface flow, coupled with
a surface runoff routine based on the kinematic wave approximation. The geotechnical
component of the model is based on a multidimensional limit equilibrium analysis,
which takes into account the basic principles of unsaturated soil mechanics. A
series of numerical simulations were carried out with various boundary conditions
and using different hydrological and geotechnical components. Boundary conditions
in terms of distributed soil depth were generated using both empirical and process-based
models. The effect of including preferential flow and soil hydraulic hysteresis
was tested together with the replacement of the infinite slope assumption with
the multidimensional limit equilibrium analysis. The results show that boundary
conditions play a crucial role in the model performance and that the introduced
hydrological (preferential flow and soil hydraulic hysteresis) and geotechnical
components (multidimensional limit equilibrium analysis) significantly improve
predictive capabilities in the presented case study.

text: "A fully distributed hydrological analysis at scales significant for water
management for present-day, and\r\nprojected future climate conditions is presented
for a catchment in the Alps. We selected the upper Rhone\r\nbasin (Switzerland)
as a test case for understanding anthropogenic impacts including climate change
on\r\nwater resources and flood risk in the Alpine area. The upper Rhone basin
contains reservoirs, river diversions and irrigated areas offering the opportunity
to study the interaction between climate change effects\r\nand hydraulic infrastructure.
Anthropogenic disturbances of the flow regime were implemented in detail\r\nin
the hydrological analysis. We downscaled climate model realizations using a methodology
that\r\naccounts for the uncertainty in climate change projections related to
the stochastic variability of precipitation and air temperature. We showed how
climate change effects on streamflow propagate from high\r\nelevation headwater
catchments to the river in the main valley by analyzing changes in several hydrological
metrics and at various temporal scales across 297 control sections. Changes in
the natural hydrological regime imposed by the existing hydraulic infrastructure
are likely larger than climate change\r\nsignals expected by the middle of the
21st century in most of the river network. Despite a strong uncertainty induced
by stochastic climate variability, we identified an elevational dependence of
climate\r\nchange impacts with a severe reduction in streamflow due to the missing
contribution of water from\r\nice melt at high-elevation and a dampened effect
downstream. Reduced ice cover and ice melt are likely\r\nto have significant implications
for hydropower production. The impacts can emerge without any additional climate
warming. A decrease of August–September discharge and an increase of hourly and
daily\r\nmaximum flows appear as plausible projected change for the most part
of the catchment. However, it is\r\nunlikely that major changes in total runoff
for the entire upper Rhone basin will occur in the next four\r\ndecades."

text: 'While the importance of ecosystem functioning is undisputed in the context
of climate change and Earth system modeling, the role of short‐scale temporal
variability of hydrometeorological forcing (~1 h) on the related ecosystem processes
remains to be fully understood. Various impacts of meteorological forcing variability
on water and carbon fluxes across a range of scales are explored here using numerical
simulations. Synthetic meteorological drivers that highlight dynamic features
of the short temporal scale in series of precipitation, temperature, and radiation
are constructed. These drivers force a mechanistic ecohydrological model that
propagates information content into the dynamics of water and carbon fluxes for
an ensemble of representative ecosystems. The focus of the analysis is on a cross‐scale
effect of the short‐scale forcing variability on the modeled evapotranspiration
and ecosystem carbon assimilation. Interannual variability of water and carbon
fluxes is emphasized in the analysis. The main study inferences are summarized
as follows: (a) short‐scale variability of meteorological input does affect water
and carbon fluxes across a wide range of time scales, spanning from the hourly
to the annual and longer scales; (b) different ecosystems respond to the various
characteristics of the short‐scale variability of the climate forcing in various
ways, depending on dominant factors limiting system productivity; (c) whenever
short‐scale variability of meteorological forcing influences primarily fast processes
such as photosynthesis, its impact on the slow‐scale variability of water and
carbon fluxes is small; and (d) whenever short‐scale variability of the meteorological
forcing impacts slow processes such as movement and storage of water in the soil,
the effects of the variability can propagate to annual and longer time scales.'

text: 'The coarse‐grained spatial representation of many terrestrial ecosystem models
hampers the importance of local‐scale heterogeneities. To address this issue,
we combine a range of observations (forest inventories, eddy flux tower data,
and remote sensing products) and modeling approaches with contrasting degrees
of abstraction. The following models are selected: (i) Lund‐Potsdam‐Jena (LPJ),
a well‐established, area‐based, dynamic global vegetation model (DGVM); (ii) LPJ‐General
Ecosystem Simulator, a hybrid, individual‐based approach that additionally considers
plant population dynamics in greater detail; and (iii) distributed in space‐LPJ,
a spatially explicit version of LPJ, operating at a fine spatial resolution (100 m × 100 m),
which uses an enhanced hydrological representation accounting for lateral connectivity
of surface and subsurface water fluxes. By comparing model simulations with a
multivariate data set available at the catchment scale, we argue that (i) local
environmental and topographic attributes that are often ignored or crudely represented
in DGVM applications exert a strong control on terrestrial ecosystem response;
(ii) the assumption of steady state vegetation and soil carbon pools at the beginning
of simulation studies (e.g., under “current conditions”), as embedded in many
DGVM applications, is in contradiction with the current state of many forests
that are often out of equilibrium; and (iii) model evaluation against vegetation
carbon fluxes does not imply an accurate simulation of vegetation carbon stocks.
Having gained insights about the magnitude of aggregation‐induced biases due to
smoothing of spatial variability at the catchment scale, we discuss the implications
of our findings with respect to the global‐scale modeling studies of carbon cycle
and we illustrate alternative ways forward.'

text: Extreme precipitation is thought to increase with warming at rates similar
to or greater than the water vapour holding capacity of the air at ~ 7% °C−1,
the so-called Clausius–Clapeyron (CC) rate. We present an empirical study of the
variability in the rates of increase in precipitation intensity with air temperature
using 30 years of 10 min and 1 h data from 59 stations in Switzerland. The analysis
is conducted on storm events rather than fixed interval data, and divided into
storm type subsets based on the presence of lightning which is expected to indicate
convection. The average rates of increase in extremes (95th percentile) of mean
event intensity computed from 10 min data are 6.5% °C−1 (no-lightning events),
8.9% °C−1 (lightning events) and 10.7% °C−1 (all events combined). For peak 10
min intensities during an event the rates are 6.9% °C−1 (no-lightning events),
9.3% °C−1 (lightning events) and 13.0% °C−1 (all events combined). Mixing of the
two storm types exaggerates the relations to air temperature. Doubled CC rates
reported by other studies are an exception in our data set, even in convective
rain. The large spatial variability in scaling rates across Switzerland suggests
that both local (orographic) and regional effects limit moisture supply and availability
in Alpine environments, especially in mountain valleys. The estimated number of
convective events has increased across Switzerland in the last 30 years, with
30% of the stations showing statistically significant changes. The changes in
intense convective storms with higher temperatures may be relevant for hydrological
risk connected with those events in the future.

text: To prevent epidemics, insect societies have evolved collective disease defences
that are highly effective at curing exposed individuals and limiting disease transmission
to healthy group members. Grooming is an important sanitary behaviour—either performed
towards oneself (self-grooming) or towards others (allogrooming)—to remove infectious
agents from the body surface of exposed individuals, but at the risk of disease
contraction by the groomer. We use garden ants (Lasius neglectus) and the fungal
pathogen Metarhizium as a model system to study how pathogen presence affects
self-grooming and allogrooming between exposed and healthy individuals. We develop
an epidemiological SIS model to explore how experimentally observed grooming patterns
affect disease spread within the colony, thereby providing a direct link between
the expression and direction of sanitary behaviours, and their effects on colony-level
epidemiology. We find that fungus-exposed ants increase self-grooming, while simultaneously
decreasing allogrooming. This behavioural modulation seems universally adaptive
and is predicted to contain disease spread in a great variety of host–pathogen
systems. In contrast, allogrooming directed towards pathogen-exposed individuals
might both increase and decrease disease risk. Our model reveals that the effect
of allogrooming depends on the balance between pathogen infectiousness and efficiency
of social host defences, which are likely to vary across host–pathogen systems.

text: Most of the currently experienced global environmental changes (rising atmospheric
CO2 concentrations, warming, altered amount and pattern of precipitation, and
increased nutrient load) directly or indirectly affect ecosystem surface energy
balance and plant transpiration. As a consequence, the relative humidity of the
air surrounding the vegetation changes, thus creating a feedback loop whose net
effect on transpiration and finally productivity is not trivial to quantify. Forcedly,
in any global change experiment with the above drivers, we can only treat small
plots, or ‘islands’, of vegetation. This means that the treated plots will likely
experience the ambient humidity conditions influenced by the surrounding, non-treated
vegetation. Experimental assessments of global change effects will thus systematically
lack modifications originating from these potentially important feedback mechanisms,
introducing a bias of unknown magnitude in all measurements of processes directly
or indirectly depending on plant transpiration. We call this potential bias the
‘island effect’. Here, we discuss its implications in various global change experiments
with plants. We also suggest ways to complement experiments using modelling approaches
and observational studies. Ultimately, there is no obvious solution to deal with
the island effect in field experiments and only models can provide an estimate
of modification of responses by these feedbacks. However, we suggest that increasing
the awareness of the island effect among both experimental researchers and modellers
will greatly improve the interpretation of vegetation responses to global change.

text: Extreme climate conditions can dramatically alter ecosystems and are expected
to become more common in thefuture; however, our understanding of species and
ecosystem responses to extreme conditions is limited. Wemust meet this challenge
by designing experiments that cover broad ranges of environmental stress, extendingto
levels well beyond those observed currently. Such experiments are important because
they can identify phys-iological, community, and biogeochemical thresholds, and
improve our understanding of mechanistic ecologi-cal responses to climate extremes.
Although natural environmental gradients can be used to observe a range ofecological
responses, manipulation experiments – including those that impose drought and
heat gradients – arenecessary to induce variation beyond common limits. Importantly,
manipulation experiments allow for deter-mination of the cause and effect of species
and ecosystem threshold responses. We present a rationale and rec-ommendations
for conducting extreme experiments that extend beyond the historical and even
the predictedranges of environmental conditions.

text: Predictions of a warmer climate over the Great Lakes region due to global
change generally agree on the magnitude of temperature changes, but precipitation
projections exhibit dependence on which General Circulation Models and emission
scenarios are chosen. To minimize model- and scenario-specific biases, we combined
information provided by the 3rd phase of the Coupled Model Intercomparison Project
database. Specifically, the results of 12 GCMs for three emission scenarios B1,
A1B, and A2 were analyzed for mid- (2046–2065) and end-century (2081–2100) intervals,
for six locations of a hydroclimatic transect of Michigan. As a result of Bayesian
Weighted Averaging, total annual precipitation averaged over all locations and
the three emission scenarios increases by 7 % (mid-)–10 % (end-century), as compared
to the control period (1961–1990). The projected changes across seasons are non-uniform
and precipitation decreases by 3 % (mid-)–5 % (end-) for the months of August
and September are likely. Further, average temperature is very likely to increase
by 2.02–2.85 °C by the mid-century and 2.58–4.73 °C by the end-century. Three
types of non-additive uncertainty sources due to climate models, anthropogenic
forcings, and climate internal variability are addressed. When compared to the
emission uncertainty, the relative magnitudes of the uncertainty types for climate
model ensemble and internal variability are 149 and 225 % for mean monthly precipitation,
and they are respectively 127 and 123 % for mean monthly temperature. A decreasing
trend of the frost days and an increasing trend of the growing season length are
identified. Also, a significant increase in the magnitude and frequency of heavy
rainfall events is projected, with relatively more pronounced changes for heavy
hourly rainfall as compared to daily events. Quantifying the inherent natural
uncertainty and projecting hourly-based extremes, the study results deliver useful
information for water resource stakeholders interested in impacts of climate change
on hydro-morphological processes.

text: Atomic form factors are widely used for the characterization of targets and
specimens, from crystallography to biology. By using recent mathematical results,
here we derive an analytical expression for the atomic form factor within the
independent particle model constructed from nonrelativistic screened hydrogenic
wave functions. The range of validity of this analytical expression is checked
by comparing the analytically obtained form factors with the ones obtained within
the Hartee-Fock method. As an example, we apply our analytical expression for
the atomic form factor to evaluate the differential cross section for Rayleigh
scattering off neutral atoms.

text: We consider real symmetric and complex Hermitian random matrices with the
additional symmetry hxy = hN-y,N-x. The matrix elements are independent (up to
the fourfold symmetry) and not necessarily identically distributed. This ensemble
naturally arises as the Fourier transform of a Gaussian orthogonal ensemble. Italso
occurs as the flip matrix model - an approximation of the two-dimensional Anderson
model at small disorder. We show that the density of states converges to the Wigner
semicircle law despite the new symmetry type. We also prove the local version
of the semicircle law on the optimal scale.

text: Changes in near-surface humidity are evaluated in relation to changes in other
meteorological variables such as air temperature, precipitation, and sunshine
duration for a 31 year period (1981–2011) using hourly time series recorded in
Switzerland. Trends in meteorological variables are analyzed at the seasonal and
subdaily scale, and changes in water vapor are tested for Clausius-Clapeyron scaling.
Results show a marked seasonality of climatic changes with a trend toward warmer,
clearer, and drier near-surface atmosphere strengthening from January to June.
During this period considerable negative trends in relative humidity are detected.
An abrupt shift in climatic trends occurs during the month of July, after which
warming trends are considerably smaller and relative humidity remains constant
or increases. An evaluation of reanalysis products demonstrates strong consistency
with station observations and when combined with teleconnection indices supports
the hypothesis that shifts in the general circulation patterns rather than local
feedbacks are the principal drivers of observed seasonality of climate change.
However, local feedbacks can play a role in enhancing summer humidity and convective
activity (lightning and evening precipitation). Subdaily changes are significant
with more pronounced daytime trends of temperature and humidity during spring
and the opposite during summer. The strong seasonality and diurnal variability
of changes in near-surface meteorology over the last three decades in Switzerland
warns against climate change impact assessments at local scale that consider uniform
changes in air temperature and assume Clausius-Clapeyron scaling for near-surface
humidity.

text: We investigate the quantum interference shifts between energetically close
states, where the state structure is observed by laser spectroscopy. We report
a compact and analytical expression that models the quantum interference induced
shift for any admixture of circular polarization of the incident laser and angle
of observation. An experimental scenario free of quantum interference can thus
be predicted with this formula. Although this study is exemplified here for muonic
deuterium, it can be applied to any other laser spectroscopy measurement of ns-n′p
frequencies of a nonrelativistic atomic system, via an ns→n′p→n′′s scheme.

text: We typically think of cells as responding to external signals independently
by regulating their gene expression levels, yet they often locally exchange information
and coordinate. Can such spatial coupling be of benefit for conveying signals
subject to gene regulatory noise? Here we extend our information-theoretic framework
for gene regulation to spatially extended systems. As an example, we consider
a lattice of nuclei responding to a concentration field of a transcriptional regulator
(the "input") by expressing a single diffusible target gene. When input
concentrations are low, diffusive coupling markedly improves information transmission;
optimal gene activation functions also systematically change. A qualitatively
new regulatory strategy emerges where individual cells respond to the input in
a nearly step-like fashion that is subsequently averaged out by strong diffusion.
While motivated by early patterning events in the Drosophila embryo, our framework
is generically applicable to spatially coupled stochastic gene expression models.

text: "We introduce a one-parametric family of tree growth models, in which branching
probabilities decrease with branch age τ as τ-α. Depending on the exponent α,
the scaling of tree depth with tree size n displays a transition between the logarithmic
scaling of random trees and an algebraic growth. At the transition (α=1) tree
depth grows as (logn)2. This anomalous scaling is in good agreement with the trend
observed in evolution of biological species, thus providing a theoretical support
for age-dependent speciation and associating it to the occurrence of a critical
point.\r\n"

text: 'We consider partially observable Markov decision processes (POMDPs) with
a set of target states and every transition is associated with an integer cost.
The optimization objec- tive we study asks to minimize the expected total cost
till the target set is reached, while ensuring that the target set is reached
almost-surely (with probability 1). We show that for integer costs approximating
the optimal cost is undecidable. For positive costs, our results are as follows:
(i) we establish matching lower and upper bounds for the optimal cost and the
bound is double exponential; (ii) we show that the problem of approximating the
optimal cost is decidable and present ap- proximation algorithms developing on
the existing algorithms for POMDPs with finite-horizon objectives. While the worst-
case running time of our algorithm is double exponential, we present efficient
stopping criteria for the algorithm and show experimentally that it performs well
in many examples.'

text: The emergence of drug resistant pathogens is a serious public health problem.
It is a long-standing goal to predict rates of resistance evolution and design
optimal treatment strategies accordingly. To this end, it is crucial to reveal
the underlying causes of drug-specific differences in the evolutionary dynamics
leading to resistance. However, it remains largely unknown why the rates of resistance
evolution via spontaneous mutations and the diversity of mutational paths vary
substantially between drugs. Here we comprehensively quantify the distribution
of fitness effects (DFE) of mutations, a key determinant of evolutionary dynamics,
in the presence of eight antibiotics representing the main modes of action. Using
precise high-throughput fitness measurements for genome-wide Escherichia coli
gene deletion strains, we find that the width of the DFE varies dramatically between
antibiotics and, contrary to conventional wisdom, for some drugs the DFE width
is lower than in the absence of stress. We show that this previously underappreciated
divergence in DFE width among antibiotics is largely caused by their distinct
drug-specific dose-response characteristics. Unlike the DFE, the magnitude of
the changes in tolerated drug concentration resulting from genome-wide mutations
is similar for most drugs but exceptionally small for the antibiotic nitrofurantoin,
i.e., mutations generally have considerably smaller resistance effects for nitrofurantoin
than for other drugs. A population genetics model predicts that resistance evolution
for drugs with this property is severely limited and confined to reproducible
mutational paths. We tested this prediction in laboratory evolution experiments
using the “morbidostat”, a device for evolving bacteria in well-controlled drug
environments. Nitrofurantoin resistance indeed evolved extremely slowly via reproducible
mutations—an almost paradoxical behavior since this drug causes DNA damage and
increases the mutation rate. Overall, we identified novel quantitative characteristics
of the evolutionary landscape that provide the conceptual foundation for predicting
the dynamics of drug resistance evolution.

text: The Morse-Smale complex can be either explicitly or implicitly represented.
Depending on the type of representation, the simplification of the Morse-Smale
complex works differently. In the explicit representation, the Morse-Smale complex
is directly simplified by explicitly reconnecting the critical points during the
simplification. In the implicit representation, on the other hand, the Morse-Smale
complex is given by a combinatorial gradient field. In this setting, the simplification
changes the combinatorial flow, which yields an indirect simplification of the
Morse-Smale complex. The topological complexity of the Morse-Smale complex is
reduced in both representations. However, the simplifications generally yield
different results. In this chapter, we emphasize properties of the two representations
that cause these differences. We also provide a complexity analysis of the two
schemes with respect to running time and memory consumption.
