Article Synopsis
- - The study examined how the threshold temperature for superfluorescence (SF) generation in CuCl quantum dots (QDs) is affected by using resonant two-photon excitation of biexcitons versus exciton excitation, revealing that higher initial population densities lead to better SF generation.
- - It was found that the threshold temperature for SF when using excitons was higher than when using biexcitons, suggesting that a higher concentration of excited dots helps establish coherence among them more quickly.
- - The research involved theoretical calculations of biexcitonic emission time profiles, which matched well with experimental results, allowing for estimations of the temperature dependence of phase relaxation times for biexcitons in the QDs.
We present the transfer of the spatially variant polarization of topologically structured light to the spatial spin texture in a semiconductor quantum well. The electron spin texture, which is a circular pattern with repeating spin-up and spin-down states whose repetition rate is determined by the topological charge, is directly excited by a vector vortex beam with a spatial helicity structure. The generated spin texture efficiently evolves into a helical spin wave pattern owing to the spin-orbit effective magnetic fields in the persistent spin helix state by controlling the spatial wave number of the excited spin mode.

- Macrolides are the preferred treatment for Mycoplasma pneumoniae infections, but resistance has been on the rise since 2000, prompting the need for effective detection methods.
- The Smart Gene® system offers a quick and compact solution for detecting M. pneumoniae and identifying mutations associated with drug resistance through a new qPCR method that produces results in just 50 minutes.
- In a study, the Smart Gene® system demonstrated high accuracy, with 98.7% sensitivity and 100% specificity, and successfully detected a mutation in 9% of tested samples, indicating its potential for use in clinical settings.
ANGUSTIFOLIA (AN) is a plant-specific subfamily of the CtBP/BARS/AN family, characterized by a plant-specific C-terminal domain of approximately 200 amino acids. Previously, we revealed that double knockout (DKO) lines of Physcomitrium (Physcomitrella) patens ANGUSTIFOLIA genes (PpAN1-1 and PpAN1-2) show defects in gametophore height and the lengths of the seta and foot region of sporophytes, by reduced cell elongation. In addition to two canonical ANs, the genome of P.
