Risk Times in Mission‐Oriented Systems
Quality and Reliability Engineering International, EarlyView.ABSTRACT This article assesses risk times in mission‐oriented systems with high safety standards. We examine critical times under two safety policies. The first requires that the system's reliability function, known the first failure of the components, must exceed a reliability level throughout the mission.

Mechanofluorochromism (MFC) of Donor–π–Acceptor (D–π–A)‐Type Fluorescent Dyes
The Chemical Record, EarlyView.Mechanofluorochromism (MFC) is a photophysical phenomenon that induces changes in fluorescent colors as well as colors of organic fluorescent dyes in the solid‐state by external mechanical stimuli. In this Personal Account, we offer an insight into the mechanism for the expression of MFC and present a direction in the molecular design toward creating D–

Robust Bernoulli Mixture Models for Credit Portfolio Risk
Mathematical Finance, EarlyView.ABSTRACT This paper presents comparison results and establishes risk bounds for credit portfolios within classes of Bernoulli mixture models, assuming conditionally independent defaults that are stochastically increasing in a common risk factor. We provide simple and interpretable conditions on conditional default probabilities that imply a comparison ...

Uniform K-stability and asymptotics of energy functionals in K\"ahler geometry
, 2018 Consider a polarized complex manifold (X,L) and a ray of positive metrics on L defined by a positive metric on a test configuration for (X,L). For most of the common functionals in K\"ahler geometry, we prove that the slope at infinity along the ray is ...

Market Insurance and Risk Pooling in U.S. Crop Insurance
Agricultural Economics, Volume 57, Issue 2, March 2026.ABSTRACT A common assumption is that multiple‐peril crop insurance markets suffer from market failures, thus justifying government intervention in the form of premium subsidies, operating allowances, and reinsurance agreements. One prominent rationale for intervention involves geographic correlation in agricultural production which leads to systemic ...

Slantwise Convection and Heat Transport in Icy Moon Oceans
Geophysical Research Letters, Volume 53, Issue 3, 16 February 2026.Abstract Ocean heat transport on icy moons shapes the ice shell topography, a primary observable of these moons. Two key processes control the heat transport: baroclinic instability driven by surface buoyancy contrasts and convective instability driven by heating from the core.

Magnetic Resonance in Medicine, Volume 95, Issue 1, Page 400-410, January 2026.Abstract Purpose To analytically define a spiral waveform and trajectory that match the constraints of gradient frequency, slew rate, and amplitude. Theory and Methods Piecewise analytical solutions for gradient waveforms under the desired constraints are derived using the circle of an involute rather than an Archimedean spiral.

Free‐breathing 3D pulmonary ventilation mapping at 0.55 T using stack‐of‐spiral out‐in bSSFP
Magnetic Resonance in Medicine, Volume 95, Issue 1, Page 430-441, January 2026.Abstract Purpose To develop a free‐breathing pulmonary imaging technique that provides three‐dimensional (3D) structural images and regional ventilation maps, and to evaluate its repeatability and accuracy compared with two‐dimensional phase‐resolved functional lung (PREFUL) and global tidal volume.
