Multi-function sensing applications based on high Q-factor multi-Fano resonances in an all-dielectric metastructure.

A multi-function sensor based on an all-dielectric metastructure for temperature and refractive index sensing simultaneously is designed and analyzed in this paper. The structure is composed of a periodic array of silicon dimers placed on the silicon dioxide substrate. By breaking the symmetry of the structure, the ideal bound states in the continuum can be converted to the quasi-bound states in the continuum, and three Fano resonances are excited in the near-infrared wavelength.

Decision-making ability limitations and brain neural activity changes in healthcare workers after mild COVID-19.

Studies have demonstrated that the novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) extensively affects brain function. Although cognitive dysfunction is considered a common manifestation in COVID-19 patients during the recovery period, the potential changes in decision-making ability, are not yet clear. Decision-making functions are essential to the work of healthcare workers.

Attentional impairment and altered brain activity in healthcare workers after mild COVID-19.

Severe acute respiratory syndrome coronavirus 2 (SARS-COV-2) is highly transmissible and pathogenic. Patients with mild cases account for the majority of those infected with coronavirus disease 2019 (COVID-19). Although there is evidence that many patients with COVID-19 have varying degrees of attentional impairment, little is known about how SARS-COV-2 affects attentional function.

Prevalence and risk factors of psychotic symptoms in middle-aged patients with first-episode drug-naïve major depressive disorder: A large-scale cross-sectional study.

Background: Psychotic symptoms are common in patients with major depressive disorder (MDD). However, few studies have assessed the incidence of comorbid psychotic symptoms in first-episode drug naïve (FEDN) MDD patients. The present study aimed to evaluate the prevalence and risk factors of psychotic symptoms in a large sample of middle-aged Chinese patients with FEDN MDD.

Molecular Simulation to Explore the Dissolution Behavior of Sulfur in Carbon Disulfide.

Soluble sulfur (S) and insoluble sulfur (IS) have different application fields, and molecular dynamics simulation can reveal their differences in solubility in solvents. It is found that in the simulated carbon disulfide (CS) solvent, soluble sulfur in the form of clusters mainly promotes the dissolution of clusters through van der Waals interaction between solvent molecules (CS) and S, and the solubility gradually increases with the increase in temperature. However, the strong interaction between polymer chains of insoluble sulfur in the form of polymer hinders the diffusion of IS into CS solvent, which is not conducive to high-temperature dissolution.
