Water availability shapes temporal patterns of extrafloral nectar secretion and ant visitation to a Neotropical legume

open access: yesPlant Biology, Volume 28, Issue 3, Page 913-923, April 2026.
Drought duration affects ant–plant interactions: extrafloral nectar quality initially increases and subsequently declines, and ant interaction patterns closely track these nectar dynamics. Abstract Mutualistic plants use non‐structural sugar (NSC) to produce carbon‐based resources to reward partners.

Quick and easy purification of murine untouched naive B cells or germinal center B cells by MACS

open access: yesSTAR Protocols, 2021
Summary: Humoral immune responses depend on the generation of high-affinity antigen-specific antibodies. Germinal center (GC) B cells are the cornerstone of this response in peripheral lymphoid organs. High purities of GC B cells, and also naive B cells,

A Method for Detection and Classification of Events in Neural Activity [PDF]

open access: yes, 2006
We present a method for the real time prediction of punctuate events in neural activity, based on the time-frequency spectrum of the signal, applicable both to continuous processes like local field potentials (LFPs) as well as to spike trains. We test it

Effect of Time‐Since‐Fire on Ant Communities in a Semi‐Arid Landscape

open access: yesEcology and Evolution, Volume 16, Issue 3, March 2026.
We sampled ants from five sites with varying fire histories (3, 5, 9, 26, and 34 years since the last fire). A total of 16,360 ants were collected, and 59 species across 20 genera were identified. Our results indicate that total ant abundance was higher in recently burnt sites and decreased with increasing time‐since‐fire, while ant species richness ...

The $L^p$ boundedness of wave operators for Schr\"odinger Operators with threshold singularities

open access: yes, 2010
Let $H=-\Delta+V$ be a Schr\"odinger operator on $L^2(\mathbb R^n)$ with real-valued potential $V$ for $n > 4$ and let $H_0=-\Delta$. If $V$ decays sufficiently, the wave operators $W_{\pm}=s-\lim_{t\to \pm\infty} e^{itH}e^{-itH_0}$ are known to be ...

Impact of an Earthquake Event on Submarine Groundwater Discharge in Jeju Island, Korea

open access: yesWater Resources Research, Volume 62, Issue 3, March 2026.
Abstract This study investigated the impact of a 4.9 magnitude earthquake on submarine groundwater discharge (SGD) and nutrient fluxes along the coast of Jeju Island, Korea. Significant negative correlations were found between salinity and dissolved inorganic nitrogen (DIN; r2 = 0.94), dissolved inorganic phosphorus (DIP; r2 = 0.53), and dissolved ...
