Metric lines in the jet space

open access: yesAnalysis and Geometry in Metric Spaces
In the realm of sub-Riemannian manifolds, a relevant question is: what are the metric lines (isometric embedding of the real line)? The space of kk-jets of a real function of one real variable xx, denoted by Jk(R,R){J}^{k}\left({\mathbb{R}},{\mathbb{R}}),

Elucidating the neuropathological and molecular heterogeneity of amyloid beta and tau in Alzheimer's disease through machine learning and transcriptomic integration

open access: yesAlzheimer's &Dementia, Volume 22, Issue 8, August 2026.
Abstract INTRODUCTION Functional brain network alterations associated with Alzheimer's disease (AD) pathology, including amyloid beta (Aβ) and phosphorylated tau (p‐tau), are difficult to interpret due to overlapping aging‐associated and non‐amyloid biological processes.

c horizontal convexity on Carnot groups

open access: yes, 2010
Given a real-valued function $c$ defined on the cartesian product of a generic Carnot group $\G$ and the first layer $V_1$ of its Lie algebra, we introduce a notion of $c$ horizontal convex ($c$ H-convex) function on $\G$ as the supremum of a suitable family of affine functions; this family is defined pointwisely, and depends strictly on the horizontal

Some Results on Maps That Factor through a Tree

open access: yesAnalysis and Geometry in Metric Spaces, 2015
We give a necessary and sufficient condition for a map deffned on a simply-connected quasi-convex metric space to factor through a tree. In case the target is the Euclidean plane and the map is Hölder continuous with exponent bigger than 1/2, such maps ...

Analysis of Human Thymopoiesis Reveals Rapid Postnatal Remodeling of Thymocytes Within the First 3 Months of Life

open access: yesEuropean Journal of Immunology, Volume 56, Issue 8, August 2026.
Human thymopoiesis undergoes a dynamic postnatal transition, revealing maximal intrathymic sjTREC production at birth, shifts in thymocyte phenotype and composition, and a transient wave of effector Vδ2+ γδ T cells during early infancy. ABSTRACT The thymus generates a diverse and self‐tolerant T‐cell repertoire.

Design and Dynamic Response Characteristics Analysis of Hydrogen Fuel Cell Ship Combined Cooling and Power Supply System

open access: yesEngineering Reports, Volume 8, Issue 8, August 2026.
An integrated hybrid energy storage and cogeneration system with CE‐DPS effectively stabilizes DC bus voltage in hydrogen fuel cell marine vessels. The proposed multi‐tier control suppresses voltage fluctuations, eliminates overshoot, and improves energy efficiency, achieving 68% exergy efficiency and 15.6% fuel savings.
