Geodiversity is an inseparable but underutilized aspect of ecological connectivity assessments under climate change

Ecography, EarlyView.
Conservation has shifted towards a climate change adaptation approach in which expected species range shifts are increasingly considered to mitigate effects of climate change and habitat fragmentation on biodiversity. As part of this, ecological connectivity needs to be ensured to support gene flow and viable populations in the face of changing ...

Optimal Parametric Search on Graphs of Bounded Tree-Width

Journal of Algorithms, 1994
Summary: We give linear-time algorithms for a class of parametric search problems on weighted graphs of bounded tree-width. We also discuss the implications of our results to approximate parametric search on planar graphs.

Seizure forecasting with epilepsy cycles: On the causality of forecasting pipelines

Epilepsia, EarlyView.
Abstract Objective Seizure risk is modulated by multiscale brain rhythms. Previous studies using cycles in electroencephalography, heart rate, and wearable data suggest the possibility of forecasting seizures days in advance. However, they commonly rely on methods requiring (days of) information from time points beyond the moment of forecast (noncausal

Competing Demographic Drivers of Hospital Expenditures: Coexistence of the Red Herring and the Steepening Effects

Health Economics, EarlyView.
ABSTRACT The fiscal sustainability of healthcare systems is increasingly strained by aging populations with two competing hypotheses dominating the literature. The Red Herring Hypothesis suggests that healthcare expenditures are driven more by proximity to death than by chronological age, while the Steepening Hypothesis examines whether expenditures ...

Mapping Alkyne Chemical Space—Classifying the Reactivity of Alkynes in Semihydrogenation and beyond Using a Data Science Framework

Helvetica Chimica Acta, EarlyView.
A data science framework integrating DFT featurization and hierarchical clustering was used to map the chemical space of over 2700 alkynes into six subsets before using experimental data for Ni3Zn‐catalyzed semihydrogenation and applying a logistic regression model to categorize substrates by reactivity.

Spatiotemporal Changes in Precipitation Concentration in the Atlantic‐European Region

International Journal of Climatology, EarlyView.
This study analyses changes in precipitation concentration using ERA5 and E‐OBS datasets. Gini index as a measure of precipitation concentration revealed a gradual expansion of areas with increasing unevenness in precipitation distribution across the Atlantic‐European region since 1961.

Parametric Modeling of Visual Search Efficiency in Real Scenes

PLOS ONE, 2015
How should the efficiency of searching for real objects in real scenes be measured? Traditionally, when searching for artificial targets, e.g., letters or rectangles, among distractors, efficiency is measured by a reaction time (RT) × Set Size function.

Decision Threshold Setting in Binary Classification Problems—A Behavioral Lens

Journal of Operations Management, EarlyView.
ABSTRACT When binary classification models are wrong, managers face misclassification costs. Although false positive outcomes imply unnecessary mitigation efforts, false negative outcomes imply overlooking the class of interest. Humans calibrate these ai models supporting operational systems by adjusting the decision threshold that translates ...

Efficient First‐Principles Inverse Design of Nanolasers

Laser &Photonics Reviews, EarlyView.
This article introduces a first‐principles inverse‐design framework for nanolasers that directly incorporates nonlinear lasing physics. By unifying steady‐state ab‐initio laser theory (SALT) with topology optimization, it reveals how spatial hole burning, gain saturation, and cavity‐emitter coupling shape laser performance, enabling efficient discovery
