Revisiting the relationship between stomatal size and speed across species – a meta‐analysis

open access: yesNew Phytologist, Volume 249, Issue 5, Page 2338-2354, March 2026.
Summary The rate of stomatal opening and closure in response to changes in light affects leaf photosynthesis and water use. However, it is unclear how strongly stomatal size (SS) and density (SD) influence stomatal conductance (gs) kinetics, and whether variation arises from methodological differences, guard cell type or degree of amphistomaty.

Barium‐Catalyzed Dehydrocoupling of Terminal Alkynes and Hydrosilanes

open access: yesChemistryEurope, Volume 4, Issue 2, February 2026.
A combined experimental, kinetic, and theoretical investigation reveals that molecular barium catalysts mediate competently the controlled dehydrocoupling of terminal alkynes and hydrosilanes for the production of alkynylsilanes. The dehydrocoupling of terminal alkynes and hydrosilanes catalyzed by alkaline‐earth complexes: calcium, strontium and, most

Universal metallic and insulating properties of one dimensional Anderson Localization : a numerical Landauer study [PDF]

open access: yes, 2009
We present results on the Anderson localization in a quasi one-dimensional metallic wire in the presence of magnetic impurities. We focus within the same numerical analysis on both the universal localized and metallic regimes, and we study the evolution ...

Simple regret for infinitely many armed bandits [PDF]

open access: yes, 2015
We consider a stochastic bandit problem with infinitely many arms. In this setting, the learner has no chance of trying all the arms even once and has to dedicate its limited number of samples only to a certain number of arms. All previous algorithms for

Secretome Profiling of Young Multipotent Stem Cells Reveals Angiogenic and Immunomodulatory Mechanisms Supporting Aged Neuromuscular Health

open access: yesAging Cell, Volume 25, Issue 2, February 2026.
Young multipotent muscle‐derived stem/progenitor cells (MDSPCs) secrete a unique profile of pro‐angiogenic and immunomodulatory proteins that are diminished with age. Systemic transplantation of young MDSPCs into naturally aged mice activates pathways in neuromuscular tissues, enhancing health and driving molecular, structural, and functional ...
