Importance Understanding the characteristics of discordance between plasma biomarkers and positron emission tomography (PET) results in Alzheimer disease (AD) is crucial for accurate interpretation findings. Objective To compare (1) medical comorbidities affecting biomarker concentrations, (2) imaging clinical features, (3) cognitive changes PET discordant concordant cases. Design, Setting, Participants This multicenter cohort study, conducted 2016 2023, included individuals with unimpaired...
Small modular reactor (SMR) structures can be constructed near power-demand sites, thereby allowing for flexible adaptation to changes in power demand and relatively short construction periods. However, owing limited high levels of performance are required terms facility protection security. To analyze the behavior reinforced-concrete (RC) under blast loads effects design parameters, dynamic nonlinear analyses required, which time-consuming. Accordingly, studies have been conducted utilizing...
Physical activity (PA) is a nonpharmacological intervention for dementia prevention. The association between PA and Alzheimer disease (AD) plasma biomarkers remains underexplored. To investigate the associations among PA; biomarkers, including β-amyloid 42/40 (Aβ42/40), phosphorylated-tau217 (ptau217), glial fibrillary acidic protein (GFAP), neurofilament light chain (NfL); cognition. This cross-sectional study included participants with without cognitive impairment recruited from multiple...
Using a two-phase double-rows linear array CCD apparatus fitted up with collecting card for special use, we collect and measure Frauhofer diffraction patterns formed by He-Ne laser through single slit double slit. The principle, the experiment device adjustment requirements are introduced. Through comparing measurement values theoretical values, find this method has advantage of precision besides quickness.
BES Collaboration has collected 58 million $J/ψ$ events at the Beijing Electron-Positron Collider (BEPC). decays provide an excellent place for studying excited nucleons and hyperons -- $N^*$, $Λ^*$, $Σ^*$ $Ξ^*$ resonances. Physics motivation, data status, partial wave analyses future prospects are presented baryon resonance program BES.

Traditional method of measuring intensity distribution diffraction (screw-driven photocell method) causes big error. This paper introduced principle, experimental devices and requirements for adjustment collecting by CCD apparatus. The curves the single-slit double-slit with different slit-width are obtained. relative light them calculated. Compared theoretical value, errors
