Integrating Grain to Ground Motion Data for Critical Rock Bridge and Slope Failure Analysis

open access: yesInternational Journal for Numerical and Analytical Methods in Geomechanics, Volume 50, Issue 16, Page 5891-5918, November 2026.
ABSTRACT Rock masses can fail catastrophically with little warning, yet their stability depends on hidden internal connections that channel forces and localise damage. Among these, rock bridges–a “known unknown” in slope mechanics–lock fractured rock and control how failure unfolds, but their concealed geometry and uncertain strength obscure where and ...

The Scaleup Costs, Size, and Statistics Challenge to Democratic Deliberation on Health Policy

open access: yesBioethics, Volume 40, Issue 9, Page 1025-1038, November 2026.
ABSTRACT Current fashion supports aligning health policy with the recommendations of deliberative forums, or mini‐publics. These forums' participants are selected randomly from the general public (sometimes with overrepresentation of direct stakeholders or of underrepresented sectors).

Quantitative maximal L2$L^2$‐regularity for viscous Hamilton–Jacobi PDEs in 2D and Mean Field Games

open access: yesBulletin of the London Mathematical Society, Volume 58, Issue 11, November 2026.
Abstract We discuss quantitative Calderón–Zygmund estimates in W2,2$W^{2,2}$ for 2D viscous Hamilton–Jacobi equations with natural growth in the gradient. We apply the result to obtain the existence of classical solutions for stationary second‐order mean field games systems in 2D with (defocusing) coupling behaving like mα$m^\alpha$ for any α>0$\alpha >

Minimal Nonnegative Solution of Nonlinear Impulsive Differential Equations on Infinite Interval

open access: yesBoundary Value Problems, 2011
The cone theory and monotone iterative technique are used to investigate the minimal nonnegative solution of nonlocal boundary value problems for second-order nonlinear impulsive differential equations on an infinite interval with an infinite number of ...

Ultra‐Weak Photon Emission as a By‐Product of Mitochondrial Oxidative Metabolism: Mechanisms, Limits, and Implications

open access: yesNanophotonics, Volume 15, Issue 20, 27 October 2026.
Mitochondrial oxidative metabolism generates ROS. Downstream chemiexcitation triplet carbonyls, singlet oxygen; produces ultra‐weak photon emission (UPE). Energetic bounds restrict well‐coupled respiration to extremely weak, red/NIR‐biased emission. Stronger visible UPE indicates elevated oxidative flux, linking measured photon counts to redox state ...

Microenvironmental Tuning in Isostructural Conjugated Metal–Organic Frameworks for Superior Photocatalytic H2O2 Generation

open access: yesAngewandte Chemie, Volume 138, Issue 41, 5 October 2026.
Two isostructural conjugated‐MOFs (Fe‐Tp and Mn‐Tp) photocatalysts were engineered with nonequivalent microenvironmental redox tuning for hydrogen peroxide production. The manganese analog engages both the oxygen reduction reaction and the water oxidation reaction while suppressing decomposition, delivering 10 487 µmol g−1 h−1 with an apparent quantum ...
