Relativistic consistency rules out GRW-Pearle collapse schemes [PDF]

open access: yesarXiv, 2010
If the outcome recorded by a detector is required to be the same in all relativistically equivalent frames of reference, then a large class of collapse models, including the GRW-Pearle scheme, is ruled out.

Chronic Stress May Amplify Gender/Sex Differences in Amygdala Reactivity to Ambiguous Emotional Stimuli

open access: yesStress and Health, Volume 41, Issue 2, April 2025.
ABSTRACT Heightened reactivity to ambiguous emotional stimuli, such as surprized faces, is a transdiagnostic psychopathology risk factor. Women show elevated amygdala activation to ambiguous emotional stimuli relative to men, which may underlie their significantly higher risk for mood disorders. Moreover, there are sex/gender differences in the effects

Genetic optimization of the Hyperloop route through the Grapevine [PDF]

open access: yesarXiv, 2015
We demonstrate a genetic algorithm that employs a versatile fitness function to optimize route selection for the Hyperloop, a proposed high speed passenger transportation system.

Efficacy of probiotic, prebiotic, synbiotic and postbiotic supplementation on gastrointestinal health in cats: systematic review and meta‐analysis

open access: yesJournal of Small Animal Practice, Volume 66, Issue 4, Page 219-235, April 2025.
Objectives The clinical efficacy of the use of probiotics, prebiotics, synbiotics and postbiotics (biotics) in cats is unknown, despite their use in daily practice. The objectives of the study is to evaluate the effectiveness of biotic supplementation in treating and preventing gastroenteropathies, and in reducing gastrointestinal signs associated with

Enantiomer-specific isotope analysis of D- and L-alanine: Nitrogen isotopic hetero- and homogeneity in microbial and chemical processes [PDF]

open access: yesEarth, Life, and Isotopes (Kyoto University Press), pp. 387-402 (2010), 2013
Nitrogen isotopic hetero- and homogeneity of D-{\alpha}-alanine and L-{\alpha}-alanine were investigated in microbial processes in the domain Bacteria and in chemical processes in symmetric organic synthesis. D-alanine is an enantiomer that is physiologically essential for microbial growth and metabolic maintenance.

Dietary selenium nanoparticles (SeNPs) mediate intestinal microbiome and microbiota‐derived metabolites regulating the growth and immunity of Nile tilapia

open access: yesJournal of the World Aquaculture Society, Volume 56, Issue 2, April 2025.
Abstract Maintaining a healthy intestine is essential for growth and host defense mechanisms of farmed fish, particularly those densely stocked. In this context, maintaining a healthy intestinal microbiota for proper digestion, absorption, and integrity of the mucosa is of utmost importance.

Enhanced Nilpotent Representations of a Cyclic Quiver [PDF]

open access: yesarXiv, 2010
We define a set of "enhanced" nilpotent quiver representations that generalizes the enhanced nilpotent cone. This set admits an action by an associated algebraic group $K$ with finitely many orbits. We define a combinatorial set that parametrizes the set of orbits under this action and we derive a purely combinatorial formula for the dimension of an ...

Limits of Yang-Mills α-connections [PDF]

open access: yesarXiv, 2017
In the spirit of recent work of Lamm, Malchiodi and Micallef in the setting of harmonic maps, we identify Yang-Mills connections obtained by approximations with respect to the Yang-Mills {\alpha}-energy. More specifically, we show that for the SU(2) Hopf fibration over the four sphere, for sufficiently small {\alpha} values the SO(4) invariant ADHM ...

Symbol, Conversational, and Societal Grounding with a Toy Robot [PDF]

open access: yesarXiv, 2017
Essential to meaningful interaction is grounding at the symbolic, conversational, and societal levels. We present ongoing work with Anki's Cozmo toy robot as a research platform where we leverage the recent words-as-classifiers model of lexical semantics in interactive reference resolution tasks for language grounding.
