Mechanical Detection of Nuclear Decays.

We report the detection of individual nuclear α decays through the mechanical recoil of the entire micron-sized particle in which the decaying nuclei are embedded. Momentum conservation ensures that such measurements are sensitive to any particles emitted in the decay, including neutral particles that may otherwise evade detection with existing techniques. Detection of the minuscule recoil of an object more than 10^{12} times more massive than the emitted particles is made possible by recently developed techniques in levitated optomechanics, which enable high-precision optical control and measurement of the mechanical motion of optically trapped particles.

Nocardiosis and other common diseases of cultured golden pompano (Trachinotus blochii) in Taiwan.

Golden pompano (Trachinotus blochii) is a carnivorous teleost cultured in the Asia-Pacific region. Fish culture in high densities and numbers results in disease outbreaks, causing huge economic losses. Here, we collected cultured golden pompanos from 2021 to 2022 and identified the pathogens isolated from the diseased fish.

Probing the sublimation kinetics of Ag, Ag@TiO, and Ag@C nanoparticles.

In this study, we used an transmission electron microscopy (TEM) heating system to investigate the sublimation-induced morphological changes of cubic Ag nanoparticles (NPs) and Ag-based core-shell structures and the influence of shell coverage on the thermal stability. In contrast to previous research performed with small Ag nanoparticles (<30 nm), here we found that large-particle Ag NPs (>50 nm) underwent a three-stage sublimation-induced morphological change at 800 °C, in the sequence uniform (I)-nonuniform (II)-uniform (III) sublimation. The (110) and (100) planes were the main sublimation planes during stages I and II.

Enhanced Piezocatalytic Activity in BiNaTiO for Water Splitting by Oxygen Vacancy Engineering.

Piezoelectric materials have demonstrated applicability in clean energy production and environmental wastewater remediation through their ability to initiate a number of catalytic reactions. In this study, we used a conventional sol-gel method to synthesize lead-free rhombohedral 3 bismuth sodium titanate (BNT) particles of various sizes. When used as a piezocatalyst to generate H through water splitting, the BNT samples provided high production rates (up to 506.

Symptoms of ADHD Affect Intrasubject Variability in Youths with Autism Spectrum Disorder: An Ex-Gaussian Analysis.

Increased intrasubject variability in reaction times (RT-ISV) is frequently found in individuals with autism spectrum disorder (ASD). However, how dimensional attention deficit/hyperactivity disorder (ADHD) symptoms impact RT-ISV in individuals with ASD remains elusive. We assessed 97 high-functioning youths with co-occurring ASD and ADHD (ASD+ADHD), 124 high-functioning youths with ASD only, 98 youths with ADHD only, and 249 typically developing youths, 8-18 years of age, using the Conners Continuous Performance Test (CCPT).

Relationship between parenting stress and informant discrepancies on symptoms of ADHD/ODD and internalizing behaviors in preschool children.

Parent and teacher ratings of child behaviors are often discrepant, and these discrepancies may be correlated with parenting stress. The present study explored whether various parenting stress factors are associated with discrepancies between parent and teacher ratings of attention-deficit/hyperactivity disorder and oppositional defiant disorder (ODD) as well as internalizing symptoms in preschool children. We recruited 299 Taiwanese preschool children (aged 4-6 years) from the community or via clinical referrals.

Variations in the efficacy of resistant maltodextrin on body fat reduction in rats fed different high-fat models.

Many studies have utilized a variety of methods to induce obesity in rodents, but they often received inconsistent results. The present study intended to use resistant maltodextrin (RMD) as a means to investigate the variations in its efficacy on body fat accumulation under the influence of four high-fat (HF) models of 23% or 40% total fat, comprising soybean oil, lard, and/or condensed milk. Results indicated that integrating condensed milk into the diets could help increase diet intake, boost energy intake, increase weight gain, and enhance fat formation.
