Tactical and Strategic Risks From Supply Disruptions in Competing Supply Chains

Naval Research Logistics (NRL), EarlyView.
ABSTRACT Supply chain disruptions can lead to both tactical (i.e., loss of short‐term sales during a disruption) and strategic (i.e., loss of long‐term market share) consequences. We model the impact of a supply disruption on competing supply chains in which two firms compete for a limited backup supply.

Burden of ischemic stroke in China from 1990 to 2050: A systematic review and analysis of Global Burden of Disease Study 2021

Neuroprotection, EarlyView.
Based on GBD 2021, the study analyzed the temporal trends of ischemic stroke (IS) burden in China from 1990 to 2021 and forecasted incidence and mortality through 2050. The absolute burden of IS in China will continue to rise by 2050, driven mainly by population aging, with faster age‐standardized incidence rate growth in females than males.

Coverage‐based rarefaction fails to quantify relative species richness

Oikos, EarlyView.
Coverage‐based rarefaction (CBR) is a high‐profile tool for assessing biodiversity that provides relative species richness estimates by leveraging the Good‐Turing index u to interpolate. In contrast to alternatives such as the Shannon and Simpson indices, CBR's main appeal is providing values in units of species. CBR is tested against a series of other

Coexisting ant species differ in ability to meet their intrinsic nutritional needs

Oikos, EarlyView.
Coexisting species are often assumed to reduce competition by foraging for foods that differ in nutrient composition, but few studies test whether field nutritional differences correspond to intrinsic differences in macronutrient selectivity. We compared field estimates of worker trophic position (tissue isotopes: δ15N) and worker tissue stoichiometry (

Supervised Protein Structure Classification Using Topological Persistence With DeltaFold

Proteins: Structure, Function, and Bioinformatics, EarlyView.
ABSTRACT Recent advances in protein structure prediction have considerably increased the number of available structures, underscoring the need for scalable and accurate methods to compare and classify this huge amount of data. Current approaches based on sequence alignment or structural superposition often lack sensitivity and/or are computationally ...
