COVID‐19 Stress and Resilience: A Longitudinal Cohort Study of First‐Year College Students

open access: yesJournal of Adolescence, Volume 98, Issue 1, Page 307-320, January 2026.
ABSTRACT Introduction The COVID‐19 pandemic affected all dimensions of the college experience. Research has explored COVID‐19 stress and resilience factors, though this study is generally cross‐sectional and lacks pre‐pandemic baseline measures. Women and sexual/gender minority (SGM) college students experienced higher levels of COVID‐19 stress but the

Effects of temporal and spatial variability in energy fluxes on phytoplankton

open access: yesLimnology and Oceanography, Volume 71, Issue 1, January 2026.
Abstract Climate change has significantly altered the energy dynamics of lakes; however, little is known of how the temporal and spatial variation in energy fluxes impacts the structure and function of lake ecosystems. This study combined long‐term (2011–2018) measurements of lake energy fluxes with environmental, nutrient, and phytoplankton data at ...

A cognitive architecture for learning in reactive environments [PDF]

open access: yes, 1986
Previous research in machine learning has viewed the process of empirical discovery as search through a space of 'theoretical' terms. In this paper, we propose a problem space for empirical discovery, specifying six complementary operators for defining ...

PROPOSAL OF DEMONSTRATION OF THE GOLDBACH’S CONJECTURE

open access: yesINTERNATIONAL JOURNAL OF MATHEMATICS AND COMPUTER RESEARCH, 2023
The Goldbach’s conjecture is the unproven mathematic assertion which states : All whole even number greater than 2 can be written as the sums of two prime numbers. It was formulated in 1742 by Christian Goldbach, it is one of the oldest unsolved problem of the theorie of number and mathematics.

From modality to millianism

open access: yesNoûs, Volume 59, Issue 4, Page 851-872, December 2025.
Abstract A new argument is offered which proceeds through epistemic possibility (for all S knows, p), cutting a trail from modality to Millianism, the controversial thesis that the semantic content of a proper name is simply its bearer. New definitions are provided for various epistemic modal notions.

Discovery Systems: From AM to CYRANO [PDF]

open access: yes, 1987
The emergence in 1976 of Doug Lenat's mathematical discovery program AM [Len76] [Len82a] was met with suprise and controversy; AM's performance seemed to bring the dream of super-intelligent machines to our doorstep, with amazingly simple methods to boot.

Understanding Mobility Through Climate Risk Perceptions

open access: yesWIREs Climate Change, Volume 16, Issue 6, November/December 2025.
Climate change risk perception—shaped by socio‐economic characteristics, climate‐related information and knowledge, cultural and political beliefs and values, and climate change experiences—influences mobility decisions through place attachment, adaptation, and livelihoods.

Structures of a synthetic antibody selected against and bound to the C‐terminal domain of Clostridium perfringens enterotoxin

open access: yesProtein Science, Volume 34, Issue 10, October 2025.
Abstract Clostridium perfringens enterotoxin (CpE) causes cytotoxic gastrointestinal disease in mammalian epithelium by binding membrane protein receptors called claudins. Claudins direct the formation of cell/cell tight junctions through oligomerization and govern the transport of molecules between individual cells.
