Photometry and Spectroscopy of the GRB 970508 Optical Counterpart
An optical transient within the error box of the gamma ray burst GRB 970508 was imaged 4 hours after the event. It displayed a strong ultraviolet excess, and reached maximum brightness 2 days later. The optical spectra did not show any emission lines, and no variations on time scales of minutes were observed for 1 hour during the decline phase ...

A surface passivation strategy using yttrium acetate to suppress Mg ion migration from the ZnMgO electron transport layer is proposed. This treatment restores oxygen vacancies on the ZnMgO surface, enhancing device stability. The Cd‐free quantum dot light‐emitting diodes demonstrate a 65.5% increase in operational lifetime with an external quantum ...

Here a transcranial photo‐biomodulation approach is developed using near‐infrared (NIR) laser on hippocampus of mice, revealing significant improvements in learning and memory ability of mice under normal and disease conditions. The improvement results from the high‐density cell‐induced NIR local energy deposition, neuronal activation, and axonogenesis

Optical Properties of Light-Scattering Standards for CCD Photometry
This paper analyzes the light-scattering standards currently used for calibration (verification) and systematic research in photo and spectrophotometry tools. The application specificities in studying the diffuse reflected and transmitted light during biomedical CCD photometry are considered.

Multi-Conjugate Adaptive Optics images of the Trapezium Cluster
Multi-Conjugate Adaptive Optics (MCAO) combines the advantages of standard adaptive optics, which provides high contrast and high spatial resolution, and of wide field ~1' imaging. Up to recently, MCAO for astronomy was limited to laboratory experiments.

Activation of Kir4.1 Channels by 2‐D08 Promotes Myelin Repair in Multiple Sclerosis
Multiple sclerosis causes myelin loss and neurological dysfunction. This study shows that 2‐D08, a small molecule targeting Kir4.1 channels, promotes OPCs differentiation via FYN tyrosine kinase phosphorylation and the FYN/MYRF pathway. It significantly improves myelin repair and motor deficits in EAE mice and marmosets, highlighting its potential as a
