Calibration of medium‐range temperature ensemble forecasts dependent on the time horizon: An assessment

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
Numerical weather prediction output necessitates calibration, as weather model systems are unable to replicate the correct statistics of observations. Such processing is especially important when predicting extreme weather. Calibration methods function by learning from prediction inadequacies during a training phase and by exploiting this information ...

Directional Deep Brain Stimulation for Parkinson's Disease: Results of an International Crossover Study With Randomized, Double‐Blind Primary Endpoint

open access: yesNeuromodulation: Technology at the Neural Interface, EarlyView., 2021
Abstract Objective Published reports on directional deep brain stimulation (DBS) have been limited to small, single‐center investigations. Therapeutic window (TW) is used to describe the range of stimulation amplitudes achieving symptom relief without side effects.

Inductive constructions for Lie bialgebras and Hopf algebras [PDF]

open access: yes, 2006
In recent years, two generalisations of the theory of Lie algebras have become prominent, namely the "semi-classical" theory of Lie bialgebras and the "quantum" theory of Hopf algebras, including the quantized enveloping algebras.

Sliding Motions on Non‐Euclidean State Spaces: A Differential‐Geometric Perspective

open access: yesInternational Journal of Robust and Nonlinear Control, EarlyView.
ABSTRACT This paper extends sliding‐mode control theory to nonlinear systems evolving on smooth manifolds. Building on differential geometric methods, we reformulate Filippov's notion of solutions, characterize well‐defined vector fields on quotient spaces, and provide a consistent geometric definition of higher‐order sliding modes.

Synergies of Geospatial and Digital Technologies for Sustainable Rural Development: A Data‐Driven Analysis of Topics and Novelty Assessment

open access: yesSustainable Development, EarlyView.
ABSTRACT The adoption of geospatial and digital technologies, including Geographic Information Systems (GIS), Building Information Modelling (BIM), Digital Twins, the Internet of Things (IoT) and Artificial Intelligence (AI), is increasingly recognised as key enablers of sustainable development.

Hatching and fledging? A meta‐analysis of the performance effects of business incubators

open access: yesStrategic Entrepreneurship Journal, EarlyView.
Abstract Research Summary Business incubators are among the most widely implemented instruments to foster entrepreneurship. Yet empirical evidence on their effectiveness remains fragmented and often contradictory. Limited research systematically compares how different types of incubators influence multiple venture performance outcomes, including ...

Heightened threats to small woodland caribou populations in Canada and key considerations for their persistence Menaces pesant sur les petites populations de caribou des bois au Canada et considérations essentielles à leur rétablissement

open access: yesWildlife Monographs, EarlyView.
Abstract Woodland caribou (Rangifer tarandus) are one of the most iconic wildlife species in Canada. These large ungulates depend on undisturbed, interconnected assemblages of mature and old‐growth conifer forests for survival, and exhibit life‐history traits typical of K‐selected species (i.e., low reproductive rates, long generation times, and slow ...

Bi[IrBi6I12], Ag3[IrBi6I12], and BixCu3–3x[IrBi6I12]: Rock‐Salt Superstructures Based on Heavy‐Atom Clusters

open access: yesZeitschrift für anorganische und allgemeine Chemie, EarlyView.
New iridium‐containing bismuth subiodides based on cuboctahedral [IrBi6I12]3− clusters adopt chain‐like or rock‐salt‐related structure variants depending on the counter‐cations. Ag3[IrBi6I12] combines silver mobility at room temperature with long‐range ordering at low temperature, while DFT calculations reveal semiconducting behavior.
