Systems Engineering, EarlyView.ABSTRACT Complex engineered systems routinely face schedule and cost overruns, along with poor post‐deployment performance. Both INCOSE and the U.S. Department of Defense (DoD) have championed Digital Engineering (DE) as a potential remedy, yet most of DE's purported benefits remain anecdotal, and its return on investment (ROI) remains poorly ...

Approximation in stochastic integer programming [PDF]
Approximation algorithms are the prevalent solution methods in the field of stochastic programming. Problems in this field are very hard to solve. Indeed, most of the research in this field has concentrated on designing solution methods that approximate ...

TorchRef: an open‐source PyTorch framework for crystallographic refinement
Journal of Applied Crystallography, EarlyView.TorchRef is an open‐source PyTorch‐based crystallographic refinement framework that exposes all refinable parameters to automatic differentiation, accelerates structure factor evaluation by about two orders of magnitude on a GPU and enables novel workflows such as direct refinement against amplitude differences in time‐resolved crystallography ...

Conserving Rodent Pests in Transition Toward Endangered Status
Integrative Zoology, EarlyView.Rodent control invariably takes place in the context of ecosystems heavily modified by agriculture. Together, they are potent drivers of rodent decline and endangerment. Nineteen percent of 2349 rodent species evaluated in the IUCN Red List of threatened species are of some conservation concern.

Intact coastal nursery rearing amid climate‐driven phenological shifts in threatened salmon
Conservation Biology, EarlyView.Abstract Literature linking phenology to climate has proliferated in recent decades and shows that climate change has reorganized seasonal opportunities worldwide. However, this literature often quantifies changes in point measures of timing (e.g., beginnings and peaks) without context about duration (e.g., rearing season length) or performance (e.g ...

Online‐optimized RAG for tool use and function calling
Decision Sciences, EarlyView.Abstract In many applications, retrieval‐augmented generation (RAG) drives tool use and function calling by embedding the (user) queries and matching them to prespecified tool/function descriptions. In this article, we address an embedding misalignment issue that often arises in practical applications due to imperfect embedding models or noisy ...

Metabolic mRNA insufficiency of single cells: Implications for drug targeting and resistance
The FEBS Journal, EarlyView.Because none of the single‐cell mRNA profiles of growing cell populations encoded any pathway towards cell growth, we used cluster‐averaged transcriptomes to estimate protein‐constrained Vmax's and identify (combinations of) subpopulation‐specific targets to overcome drug resistance. (Graphical Abstract was created in BioRender. Liu, Y. (2026). https://

Scaling of prehospital blood: A model describing impact on U.S. blood donors, distribution and cost
Transfusion, EarlyView.Abstract Background Prehospital transfusion improves survival in traumatic and medical hemorrhage, but the blood supply implications of scaling this capability across U.S. emergency medical services (EMS) systems are unclear. Study Design and Methods We developed an analytic model incorporating national estimates of prehospital transfusion demand, EMS ...
