Mayo Normative Studies: regression-based normative data for remote self-administration of the Stricker Learning Span, Symbols Test, and Mayo Test Drive Screening Battery Composite and validation in individuals with mild cognitive impairment and dementia.

Few normative data for unsupervised, remotely-administered computerized cognitive measures are available. We examined variables to include in normative models for Mayo Test Drive (MTD, a multi-device remote cognitive assessment platform) measures, developed normative data, and validated the norms. 1240 Cognitively Unimpaired (CU) adults ages 32-100 years (96% White) from the Mayo Clinic Study of Aging and Mayo Alzheimer's Disease Research Center with Clinical Dementia Rating of 0 were included.

Is Excretory Phase Computerized Tomography Important for Evaluation of Pediatric High-Grade Renal Trauma?

Purpose: There are no standardized guidelines for evaluation of pediatric renal trauma. We hypothesize that screening radiographic studies performed to rule out traumatic renal injuries in children can initially be evaluated by contrast-enhanced CT scans that lack an excretory phase.

Materials And Methods: We retrospectively collected data from five pediatric trauma centers between 2007-2020.

Direct measurement of fluorocarbon radicals in the thermal destruction of perfluorohexanoic acid using photoionization mass spectrometry.

Thermal destruction is a critical cornerstone of addressing the rampant contamination of natural resources with per- and polyfluoroalkyl substances (PFAS). However, grave concerns associated with stack emissions from incineration exist because mechanistic studies have thus far relied on ex situ analyses of end products and theoretical calculations. Here, we used synchrotron-based vacuum ultraviolet photoionization mass spectrometry to study the pyrolysis of a representative PFAS-perfluorohexanoic acid-and provide direct evidence of fluorocarbon radicals and intermediates.

Improved Performance of Catalysts Containing Pt, Pt-Sn, and V in the Dehydrogenation of -Butane by Radio-Frequency Induction Heating.

Due to an abundance of shale gas, manufacturers are interested in meeting increased demands for alkenes, especially -alkenes, by the dehydrogenation of light alkanes. While the catalysts for these reactions have been studied for many years, alkene selectivity and deactivation remain challenging problems. This work addresses these problems by the substitution of a localized indirect heating method (radio-frequency induction heating, RF-IH) for more traditional process heating employing steam or burners (e.

Anthropogenic Impacts on Bark and Ambrosia Beetle Assemblages in Tropical Montane Forest in Northern Borneo.

Anthropogenic disturbances, such as forest conversion, have a profound impact on species distributions and biodiversity in tropical forests. This study aimed to determine the diversity and distribution of bark and ambrosia beetles (Curculionidae: Scolytinae and Platypodinae) across three forest types: Primary Forest (PF), Disturbed Forest (DF), and Rubber Plantation (RP) in southern Sabah, Malaysia. We analyzed biweekly data obtained from ethanol-baited traps over three years, from April 2017 to May 2020, which included 7257 individuals from 154 species.
