Article Abstract
Within-person variation in cognitive performance is linked to pathological aging. Cognitive fluctuations have not been analyzed using cognitive process models, such as the diffusion model, to characterize which cognitive processes contribute to variability in cognition. We collected 21 daily assessments of attention and personality in younger adults, healthy older adults, and those with mild cognitive impairment. We employed mixed-effects location scale models to analyze group differences on mean diffusion parameters and daily variability. Discussion focuses on how these methods extend our understanding of how cognitive deficits might appear in aging and disease and the moderating influence of daily personality.

Cadmium (Cd) contamination in water poses a critical global challenge. A novel nanocomposite, montmorillonite (Mt)-supported nanoscale zero-valent iron (Mt-nZVI), synthesized by liquid phase reduction, offers a promising method for effectively removing Cd. The material underwent characterization through various techniques, including X-ray diffraction (XRD) and Scanning Electron Microscope(SEM).

Introduction: The vulnerability of white matter (WM) in acute and chronic moderate-severe traumatic brain injury (TBI) has been established. In concussion syndromes, including preclinical rodent models, lacking are comprehensive longitudinal studies spanning the mouse lifespan. We previously reported early WM modifications using clinically relevant neuroimaging and histological measures in a model of juvenile concussion at one month post injury (mpi) who then exhibited cognitive deficits at 12mpi.

Escalating concentrations of norfloxacin (NFX) in surface and wastewaters demand sustainable remediation strategies. In this study, dual-functional hydrochars were synthesized from argan nut shells (ArNS) via hydrothermal carbonization (HTC), with process conditions optimized by varying temperature (150-200 °C) and residence time (2-6 h). Among the materials, H1:5@150-4-prepared at 150 °C for 4 h with a biomass-to-water ratio of 1:5-exhibited the best performance, achieving a monolayer NFX adsorption capacity of 27.

Prior researches on global-local processing have focused on hierarchical objects in the visual modality, while the real-world involves multisensory interactions. The present study investigated whether the simultaneous presentation of auditory stimuli influences the recognition of visually hierarchical objects. We added four types of auditory stimuli to the traditional visual hierarchical letters paradigm:no sound (visual-only), a pure tone, a spoken letter that was congruent with the required response (response-congruent), or a spoken letter that was incongruent with it (response-incongruent).

In order to validate some assumptions and calculations of Johnson and Ettinger's model, a mapping of measured VOC fluxes in a heavily contaminated building was undertaken. To this end, both advective and diffusive flux measurements were carried out under real conditions. Diffusive fluxes were measured with flux chambers recording the initial concentration rise during the first minutes.
