Annually Resolved Monsoon Onset and Withdrawal Dates Across the Himalayas Derived From Local Precipitation Statistics
(2020)Geophysical Research LettersA local and flexible definition of the monsoon season based on hydrological evidence is important for the understanding and management of Himalayan water resources. Here, we present an objective statistical method to retrieve seasonal hydrometeorological transitions. Applied to daily rainfall data (1951–2015), this method shows an average longitudinal delay of ~15 days, with later monsoon onset and earlier withdrawal in the western Himalaya, ...Journal Article -
Weyl fermions, Fermi arcs, and minority-spin carriers in ferromagnetic CoS2
(2020)Science AdvancesMagnetic Weyl semimetals are a newly discovered class of topological materials that may serve as a platform for exotic phenomena, such as axion insulators or the quantum anomalous Hall effect. Here, we use angle-resolved photoelectron spectroscopy and ab initio calculations to discover Weyl cones in CoS2, a ferromagnet with pyrite structure that has been long studied as a candidate for half-metallicity, which makes it an attractive material ...Journal Article -
Comparative Analysis of Pesticide Use Determinants Among Smallholder Farmers From Costa Rica and Uganda
(2020)Environmental Health InsightsPesticides are used globally in agriculture and pose a threat to the health of farmers, communities, and the environment. Smallholder farmers in low- and middle-income countries have generally a low socio-economic status and educational level. Consequently, they are particularly vulnerable to negative impacts of pesticides on their health, yields, or land. In a Knowledge, Attitude, and Practices study, we compared the pest management ...Journal Article -
Neurocognitive dynamics of near-threshold voice signal detection and affective voice evaluation
(2020)Science AdvancesCommunication and voice signal detection in noisy environments are universal tasks for many species. The fundamental problem of detecting voice signals in noise (VIN) is underinvestigated especially in its temporal dynamic properties. We investigated VIN as a dynamic signal-to-noise ratio (SNR) problem to determine the neurocognitive dynamics of subthreshold evidence accrual and near-threshold voice signal detection. Experiment 1 showed ...Journal Article -
Predicting Subjective Recovery from Lower Limb Surgery Using Consumer Wearables
(2020)Digital BiomarkersIntroduction: A major challenge in the monitoring of rehabilitation is the lack of long-term individual baseline data which would enable accurate and objective assessment of functional recovery. Consumer-grade wearable devices enable the tracking of individual everyday functioning prior to illness or other medical events which necessitate the monitoring of recovery trajectories. Methods: For 1,324 individuals who underwent surgery on a ...Journal Article -
Numerical modeling of tectonic underplating in accretionary wedge systems
(2020)GeosphereMany fossil and active accretionary wedge systems show signs of tectonic underplating, which denotes accretion of underthrust material to the base of the wedge. Underplating is a viable process for thickening of the rear part of accretionary wedges, for example as a response to horizontal growth perpendicular to strike. Here, numerical experiments with a visco-elasto-plastic rheology are applied to test the importance of backstop geometry, ...Journal Article -
Seasonal Carbon Dynamics in the Near‐Global Ocean
(2020)Global Biogeochemical CyclesThe seasonal cycle represents one of the largest signals of dissolved inorganic carbon (DIC) in the ocean, yet these seasonal variations are not well established at a global scale. Here, we present the Mapped Observation‐Based Oceanic DIC (MOBO‐DIC) product, a monthly DIC climatology developed based on the DIC measurements from GLODAPv2.2019 and a two‐step neural network method to interpolate and map the measurements. MOBO‐DIC extends ...Journal Article -
Downscaling climate projections over large and data sparse regions: Methodological application in the Zambezi River Basin
(2020)International Journal of ClimatologyClimate impact studies often require climate data at a higher space–time resolution than is available from global and regional climate models. Weather generator (WG) models, generally designed for mesoscale applications (e.g., 101–105 km2), are popular and widely used tools to downscale climate data to finer resolution. One advantage of using WGs is their ability to generate the necessary climate variables for impact studies in data sparse ...Journal Article -
The Pitfalls in Nonaqueous Electrochemistry of Al-Ion and Al Dual-Ion Batteries
(2020)Advanced Energy MaterialsThe quest for cost-effective and TWh-scale stationary energy storage systems has caused a surge of research on novel post-Li-ion batteries that consist solely of abundant chemical elements. Nonaqueous Al batteries, inter alia, are appealing as an inexpensive electrochemical technology owing to the high natural abundance of aluminum. A critical assessment of the literature on Al batteries, however, points to numerous misconceptions in this ...Journal Article -
Monster mash: A single-view approach to casual 3D modeling and animation
(2020)ACM Transactions on GraphicsWe present a new framework for sketch-based modeling and animation of 3D organic shapes that can work entirely in an intuitive 2D domain, enabling a playful, casual experience. Unlike previous sketch-based tools, our approach does not require a tedious part-based multi-view workflow with the explicit specification of an animation rig. Instead, we combine 3D inflation with a novel rigidity-preserving, layered deformation model, ARAP-L, to ...Journal Article
