text: Groundwater is a key water resource in semiarid and seasonally dry regions
around the world, which is replenished by intermittent precipitation events and
mediated by vegetation, soil, and regolith properties. Here, a climate reconstruction
of 4500 years for the Jerusalem region was used to determine the relation between
climate, vegetation, and groundwater recharge. Despite changes in air temperature
and vegetation characteristics, simulated recharge remained linearly related to
precipitation over the entire analyzed period, with drier decades having lower
rates of recharge for a given annual precipitation due to soil memory effects.
We show that in recent decades, the lack of changes in the precipitation–groundwater
recharge relation results from the compensating responses of vegetation to increasing
CO2, i.e., increased leaf area and reduced stomatal conductance. This multicentury
relation is expected to be modified by climate change, with changes up to −20%
in recharge for unchanged precipitation, potentially jeopardizing water resource
availability.

text: 'Model fidelity and accuracy in process representations have been the crux
of scientific hydrological modeling, creating a pressing need for a better linkage
between the development of hydrological models and the growing number of data
sources and measurement techniques. Improved representation of process dynamics
in hydrological models can provide new insights into complex hydrological systems
and point out less understood natural phenomena that need further investigation.
This special issue includes contributions that offer potential solutions and strategies
to improve and test the representation of hydrological processes. We have organized
the special issue contributions into four topical categories: (a) Beyond streamflow,
which looks into the power of complementary data sources in addition to traditionally
used streamflow for process inference. (b) Challenge of subsurface hydrology,
that reflects on lesser understood processes under the surface and their impact
on the model structure. (c) Evaporation in hydrological modeling, linking ecological
aspects to the hydrological functioning of the natural system. Finally, (d) top
down vs. bottom up modeling approaches, relied upon for process representation
analysis. The special issue and our reflection on the contributions present a
snapshot of ongoing efforts for integrating new concepts, knowledge, and data
in process representation in hydrological models.'

text: 'We consider a totally asymmetric simple exclusion process (TASEP) consisting
of particles on a lattice that require binding by a "token" to move. Using a combination
of theory and simulations, we address the following questions: (i) How token binding
kinetics affects the current-density relation; (ii) How the current-density relation
depends on the scarcity of tokens; (iii) How tokens propagate the effects of the
locally-imposed disorder (such a slow site) over the entire lattice; (iv) How
a shared pool of tokens couples concurrent TASEPs running on multiple lattices;
(v) How our results translate to TASEPs with open boundaries that exchange particles
with the reservoir. Since real particle motion (including in systems that inspired
the standard TASEP model, e.g., protein synthesis or movement of molecular motors)
is often catalyzed, regulated, actuated, or otherwise mediated, the token-driven
TASEP dynamics analyzed in this paper should allow for a better understanding
of real systems and enable a closer match between TASEP theory and experimental
observations.'

text: Increasing urban green spaces and canopy cover requires careful planning of
irrigation strategies, especially in arid and semiarid areas. This study investigates
how vegetation cover and irrigation affect the water balance and vegetation productivity
of a small urban reserve in the Melbourne metropolitan area, Australia. Using
a mechanistic ecohydrological model, a series of numerical experiments were carried
out for the period 1999–2018, which included a prolonged drought. Results indicated
that irrigation played an essential role in helping both trees and grass productivity
by increasing soil moisture and vegetation water access during the drought. With
10% tree cover, grass benefitted more than trees by increasing irrigation, and
trees coped well with drought even without additional water. However, trees strongly
relied on irrigation to maintain productivity when tree cover increased, highlighting
the need for a sustainable balance between increasing urban greening and water
conservation. Differences in soil properties and rooting strategies were also
found to strongly modify the need for irrigation and the competition for water.
These results provide quantitative insights on how increasing tree cover and vegetation
diversity may impact irrigation requirements, highlighting the key role of mechanistic
numerical models to support urban planners in the evaluation and design of urban
green spaces.

text: Atmospheric carbon dioxide concentration ([CO 2 ]) is increasing, which increases
leaf-scalephotosynthesis and intrinsic water-use efficiency. These direct responses
have the potential toincrease plant growth, vegetation biomass, and soil organic
matter; transferring carbon from theatmosphere into terrestrial ecosystems (a
carbon sink). A substantial global terrestrial carbon sinkwould slow the rate
of [CO 2] increase and thus climate change. However, ecosystem CO2responses are
complex or confounded by concurrent changes in multiple agents of global changeand
evidence for a [CO 2]-driven terrestrial carbon sink can appear contradictory.
Here wesynthesize theory and broad, multidisciplinary evidence for the effects
of increasing [CO 2](iCO 2) on the global terrestrial carbon sink. Evidence suggests
a substantial increase in globalphotosynthesis since pre-industrial times. Established
theory, supported by experiments,indicates that iCO 2 is likely responsible for
about half of the increase. Global carbon budgeting,atmospheric data, and forest
inventories indicate a historical carbon sink, and these apparentiCO 2 responses
are high in comparison to experiments and predictions from theory. Plantmortality
and soil carbon iCO 2 responses are highly uncertain. In conclusion, a range of
evidencesupports a positive terrestrial carbon sink in response to iCO2 , albeit
with uncertain magnitudeand strong suggestion of a role for additional agents
of global change.

text: We formulate and prove an analog of Poonen’s finite-field Bertini theorem
with Taylor conditions that holds in the Grothendieck ring of varieties. This
gives a broad generalization of the work of Vakil and Wood, who treated the case
of smooth hypersurface sections, and is made possible by the use of motivic Euler
products to write down candidate motivic probabilities. As applications, we give
motivic analogs of many results in arithmetic statistics that have been proven
using Poonen’s sieve, including work of Bucur and Kedlaya on complete intersections
and Erman and Wood on semiample Bertini theorems.

text: We study the density of rational points on a higher-dimensional orbifold (Pn−1,Δ)
when Δ is a Q-divisor involving hyperplanes. This allows us to address a question
of Tanimoto about whether the set of rational points on such an orbifold constitutes
a thin set. Our approach relies on the Hardy–Littlewood circle method to first
study an asymptotic version of Waring’s problem for mixed powers. In doing so
we make crucial use of the recent resolution of the main conjecture in Vinogradov’s
mean value theorem, due to Bourgain–Demeter–Guth and Wooley.

text: In this paper, we investigate the distribution of the maximum of partial sums
of families of m -periodic complex-valued functions satisfying certain conditions.
We obtain precise uniform estimates for the distribution function of this maximum
in a near-optimal range. Our results apply to partial sums of Kloosterman sums
and other families of ℓ -adic trace functions, and are as strong as those obtained
by Bober, Goldmakher, Granville and Koukoulopoulos for character sums. In particular,
we improve on the recent work of the third author for Birch sums. However, unlike
character sums, we are able to construct families of m -periodic complex-valued
functions which satisfy our conditions, but for which the Pólya–Vinogradov inequality
is sharp.

text: "Alpine grasslands sustain local economy by providing fodder for livestock.
Intensive fertilization is common to enhance their yields, thus creating negative
externalities on water quality that are difficult to evaluate without reliable
estimates of nutrient fluxes. We apply a mechanistic ecosystem model, seamlessly
integrating land-surface energy balance, soil hydrology, vegetation dynamics,
and soil biogeochemistry, aiming at assessing the grassland response to fertilization.
We simulate the major water, carbon, nutrient, and energy fluxes of nine grassland
plots across the broad European Alpine region. We provide an interdisciplinary
model evaluation by confirming its performance against observed variables from
different datasets. Subsequently, we apply the model to test the influence of
fertilization practices on grassland yields and nitrate (NO3) losses through leaching
under both current and modified climate scenarios.\r\n\r\nDespite the generally
low NO3 concentration in groundwater recharge, the variability across sites is
remarkable, which is mostly (but not exclusively) dictated by elevation. In high-Alpine
sites, short growing seasons lead to less efficient nitrogen (N) uptake for biomass
production. This combined with lower evapotranspiration rates results in higher
amounts of drainage and NO3 leaching to groundwater. Scenarios with increased
temperature lead to a longer growing season characterized by higher biomass production
and, consequently, to a reduction of water leakage and N leaching. While the intersite
variability is maintained, climate change impacts are stronger on sites at higher
elevations.\r\n\r\nThe local soil hydrology has a crucial role in driving the
NO3 use efficiency. The commonly applied fixed threshold limit on fertilizer N
input is suboptimal. We suggest that major hydrological and soil property differences
across sites should be considered in the delineation of best practices or regulations
for management. Using distributed maps informed with key soil and climatic attributes
or systematically implementing integrated ecosystem models as shown here can contribute
to achieving more sustainable practices."

text: Mountainous catchments cover a broad range of elevations and their response
to a warming climate is expected to vary significantly in space. Nevertheless,
studies on climate change impacts typically examine the changes in flow statistics
only at the catchment outlet. In this study, we instead demonstrate the high variability
of the hydrological response to climate change at the sub-catchment scale, investigating
in detail the contribution of all components of the hydrological cycle in two
mountainous catchments (Thur and Kleine Emme) in the Swiss Alps. The analysis
was conducted with a two-dimensional weather generator model that simulated gridded
climate variables at an hourly and 2-km resolution until the end of the 21st century
for the RCP8.5 emission scenario. The climate ensemble was used as input into
a distributed hydrological model to estimate the changes in hydrological processes
at 100-m and hourly resolutions. Climate models show that precipitation intensifies
during winter but weakens during summer in the order of ± 5–10% toward the end
of the century. Temperature will rise by up to 4°C, leading to a 50% reduction
in snowmelt, 10% increase in evapotranspiration, and shift in precipitation type
from snowfall to rainfall. As a result, streamflow is projected to increase by
40% in winter but decrease by 20% to 40% during summer, with winter floods becoming
more frequent. The changes to streamflow (mean and extreme low and high flows)
at the sub-catchments show a strong dependency with elevation. In contrast to
the small changes projected at the outlet of the catchments, streamflow shows
a reduction at higher elevations (up to −20% change in mean streamflow for sub-catchments
at elevations exceeding 1400 m) and an increase at lower elevations (up to +5%
for Kleine Emme and +20% for the Thur at elevations below 600 m). These impacts
are tied to the changes in precipitation, as well as changes in snowmelt (at high
elevation) and evapotranspiration (at low elevation). The results reveal the causes
and diversity of hydrological response to climate change, emphasizing the importance
of investigating the distributed impacts of climate change in mountainous environments.

text: This study evaluates the simulation of water balance components at half-hourly
time steps from the Canadian Land Surface Scheme (CLASS) when driven by a 500-year
stochastic meteorological data set produced by the Advanced WEather GENerator
(AWE-GEN) at two boreal sites with contrasting water availability. The CLASS was
driven by ERA5 reanalysis data (CLASS-CTL) over 39 years and its output was used
as a surrogate for land surface observations. At both sites, the mean monthly
and annual values of all meteorological variables used to drive CLASS, including
precipitation, are well captured by AWE-GEN, but their variability is, sometimes,
biased. In general, CLASS driven by stochastic data (CLASS-WG) tends to produce
higher evapotranspiration compared to values simulated by CLASS-CTL, especially
during spring and summer at the wet site. The interannual evapotranspiration-precipitation
and runoff-precipitation relationships derived from CLASS-WG and those derived
from CLASS-CTL were very similar to each other at the dry site; they both indicate
that evapotranspiration and runoff are limited by water availability. At the wet
site, however, CLASS-WG only captured well the interannual runoff-precipitation
relationship. The sensitivity analysis shows that CLASS water fluxes are particularly
affected by the replacement of physically consistent input time series of incoming
short-wave radiation, precipitation, temperature, and specific humidity. In conclusion,
the results show that even though a weather generator can produce coherent climate
time series, the use of this synthetic data as meteorological forcing in a physically
based land surface model does not necessarily reproduce the complex surface processes,
such as the surface water fluxes. More studies are encouraged to further analyze
the constraints of this framework.

text: Flooding impacts are on the rise globally, and concentrated in urban areas.
Currently, there are no operational systems to forecast flooding at spatial resolutions
that can facilitate emergency preparedness and response actions mitigating flood
impacts. We present a framework for real-time flood modeling and uncertainty quantification
that combines the physics of fluid motion with advances in probabilistic methods.
The framework overcomes the prohibitive computational demands of high-fidelity
modeling in real-time by using a probabilistic learning method relying on surrogate
models that are trained prior to a flood event. This shifts the overwhelming burden
of computation to the trivial problem of data storage, and enables forecasting
of both flood hazard and its uncertainty at scales that are vital for time-critical
decision-making before and during extreme events. The framework has the potential
to improve flood prediction and analysis and can be extended to other hazard assessments
requiring intense high-fidelity computations in real-time.

text: Peruvian glaciers are important contributors to dry season runoff for agriculture
and hydropower, but they are at risk of disappearing due to climate change. We
applied a physically based, energy balance melt model at five on‐glacier sites
within the Peruvian Cordilleras Blanca and Vilcanota. Net shortwave radiation
dominates the energy balance, and despite this flux being higher in the dry season,
melt rates are lower due to losses from net longwave radiation and the latent
heat flux. The sensible heat flux is a relatively small contributor to melt energy.
At three of the sites the wet season snowpack was discontinuous, forming and melting
within a daily to weekly timescale, and resulting in highly variable melt rates
closely related to precipitation dynamics. Cold air temperatures due to a strong
La Niña year at Shallap Glacier (Cordillera Blanca) resulted in a continuous wet
season snowpack, significantly reducing wet season ablation. Sublimation was most
important at the highest site in the accumulation zone of the Quelccaya Ice Cap
(Cordillera Vilcanota), accounting for 81% of ablation, compared to 2%–4% for
the other sites. Air temperature and precipitation inputs were perturbed to investigate
the climate sensitivity of the five glaciers. At the lower sites warmer air temperatures
resulted in a switch from snowfall to rain, so that ablation was increased via
the decrease in albedo and increase in net shortwave radiation. At the top of
Quelccaya Ice Cap warming caused melting to replace sublimation so that ablation
increased nonlinearly with air temperature.

text: Defining plant hydraulic traits is central to the quantification of ecohydrological
processes ranging from land-atmosphere interactions, to tree mortality and water-carbon
budgets. A key plant trait is the xylem specific hydraulic conductivity (Kx),
that describes the plant's vascular system capacity to transport water. While
xylem's vessels and tracheids are dead upon maturity, the xylem is neither inert
nor deadwood, various components of the sapwood and surrounding tissue remaining
alive and functional. Moreover, the established definition of Kx assumes linear
relations between water flux and pressure gradient by tacitly considering the
xylem as a “passive conduit”. Here, we re-examine this notion of an inert xylem
by systematically characterizing xylem flow in several woody plants using Kx measurements
under constant and cyclic pressure gradients. Results show a temporal and pressure
gradient dependence of Kx. Additionally, microscopic features in “living branches”
are irreversibly modified upon drying of the xylem, thus differentiating the macroscopic
definition of Kx for living and dead xylem. The findings highlight the picture
of the xylem as a complex and delicate conductive system whose hydraulic behaviour
transcends a passive gradient-based flow. The study sheds new light on xylem conceptualization,
conductivity measurement protocols, in situ long-distance water transport and
ecosystem modelling.

text: Climate change impacts on sediment production and transfer processes on hillslopes
and through channels are governed by possible changes in precipitation, runoff,
and air temperature. These hydrological and geomorphological impacts are difficult
to predict in temperature‐sensitive Alpine environments. In this study, we combined
a stochastic weather generator model with the most current climate change projections
to feed a hillslope‐channel sediment cascade model for a major debris‐flow system
in the Swiss Alps (the Illgraben). This allowed us to quantify climate change
impacts and their uncertainties on sediment yield and the number of debris flows
at hourly temporal resolution. We show that projected changes in precipitation
and air temperature lead to a reduction in both sediment yield (−48%) and debris‐flow
occurrence (−23%). This change is caused by a decrease in sediment supply from
hillslopes, which is driven by frost‐weathering. Additionally, we conduct model
experiments that show the sensitivity of projected changes in sediment yield and
debris‐flow hazard to basin elevation, with important implications for assessing
natural hazards and risks in mountain environments. Future changes in hydrological
and sediment fluxes are characterized by high uncertainty, mainly due to irreducible
internal climate variability. Therefore, this stochastic uncertainty needs to
be considered in climate change impact assessments for geomorphic systems.

text: Since the inception of Bitcoin, a plethora of distributed ledgers differing
in design and purpose has been created. While by design, blockchains provide no
means to securely communicate with external systems, numerous attempts towards
trustless cross-chain communication have been proposed over the years. Today,
cross-chain communication (CCC) plays a fundamental role in cryptocurrency exchanges,
scalability efforts via sharding, extension of existing systems through sidechains,
and bootstrapping of new blockchains. Unfortunately, existing proposals are designed
ad-hoc for specific use-cases, making it hard to gain confidence in their correctness
and composability. We provide the first systematic exposition of cross-chain communication
protocols. We formalize the underlying research problem and show that CCC is impossible
without a trusted third party, contrary to common beliefs in the blockchain community.
With this result in mind, we develop a framework to design new and evaluate existing
CCC protocols, focusing on the inherent trust assumptions thereof, and derive
a classification covering the field of cross-chain communication to date. We conclude
by discussing open challenges for CCC research and the implications of interoperability
on the security and privacy of blockchains.

text: A two-part successive syndrome-check decoding of polar codes is proposed with
the first part successively refining the received codeword and the second part
checking its syndrome. A new formulation of the successive-cancellation (SC) decoding
algorithm is presented that allows for successively refining the received codeword
by comparing the log-likelihood ratio value of a frozen bit with its predefined
value. The syndrome of the refined received codeword is then checked for possible
errors. In case there are no errors, the decoding process is terminated. Otherwise,
the decoder continues to refine the received codeword. The proposed method is
extended to the case of SC list (SCL) decoding by terminating the decoding process
when the syndrome of the best candidate in the list indicates no errors. Simulation
results show that the proposed method reduces the time-complexity of SC and SCL
decoders and their fast variants, especially at high signal-to-noise ratios.

text: 'We present a faster symbolic algorithm for the following central problem
in probabilistic verification: Compute the maximal end-component (MEC) decomposition
of Markov decision processes (MDPs). This problem generalizes the SCC decomposition
problem of graphs and closed recurrent sets of Markov chains. The model of symbolic
algorithms is widely used in formal verification and model-checking, where access
to the input model is restricted to only symbolic operations (e.g., basic set
operations and computation of one-step neighborhood). For an input MDP with n vertices
and m edges, the classical symbolic algorithm from the 1990s for the MEC decomposition
requires O(n2) symbolic operations and O(1) symbolic space. The only other
symbolic algorithm for the MEC decomposition requires O(nm−−√) symbolic operations
and O(m−−√) symbolic space. A main open question is whether the worst-case O(n2) bound
for symbolic operations can be beaten. We present a symbolic algorithm that requires O˜(n1.5) symbolic
operations and O˜(n−−√) symbolic space. Moreover, the parametrization of our
algorithm provides a trade-off between symbolic operations and symbolic space:
for all 0<ϵ≤1/2 the symbolic algorithm requires O˜(n2−ϵ) symbolic operations
and O˜(nϵ) symbolic space ( O˜ hides poly-logarithmic factors). Using our techniques
we present faster algorithms for computing the almost-sure winning regions of ω
-regular objectives for MDPs. We consider the canonical parity objectives for ω
-regular objectives, and for parity objectives with d -priorities we present
an algorithm that computes the almost-sure winning region with O˜(n2−ϵ) symbolic
operations and O˜(nϵ) symbolic space, for all 0<ϵ≤1/2 .'
