Resonance frequency prediction of dielectric antennas for liquid sensing via support vector regression.

This paper presents a slot antenna integrated with a split ring resonator (SRR) and feed line, designed to achieve a high Q-factor while maximizing channel capacity utilization. By incorporating a lens into the dielectric resonator antenna (DRA), we enhance both bandwidth and directivity, with the dielectric material's permittivity serving as a key control parameter for radiation characteristics. We explore water and ethanol as controllable dielectrics within the terahertz (THz) frequency range (0.

Central memory T cells are the most effective precursors of resident memory T cells in human skin.

The circulating precursor cells that give rise to human resident memory T cells (T) are poorly characterized. We used an in vitro differentiation system and human skin-grafted mice to study T generation from circulating human memory T cell subsets. In vitro T differentiation was associated with functional changes, including enhanced IL-17A production and FOXP3 expression in CD4 T cells and granzyme B production in CD8 T cells, changes that mirrored the phenotype of T cells in healthy human skin.

Doxycycline-induced cholestatic liver injury.

Doxycycline-induced liver injury is a rare phenomenon, with an unclear clinical course and etiopathogenesis. The onset of injury may be acute-to-subacute, with a pattern ranging from hepatocellular or cholestatic to mixed, and it often lasts up to several weeks. We present a case of cholestatic liver injury secondary to doxycycline use in a middle-aged woman.

Types of Assays for SARS-CoV-2 Testing: A Review.

Clinical laboratory testing routinely provides actionable results, which help direct patient care in the inpatient and outpatient settings. Since December 2019, a novel coronavirus (SARS-CoV-2) has been causing disease (COVID-19 [coronavirus disease 2019]) in patients, beginning in China and now extending worldwide. In this context of a novel viral pandemic, clinical laboratories have developed multiple novel assays for SARS-CoV-2 diagnosis and for managing patients afflicted with this illness.
