Atacama Large Aperture Submillimeter Telescope (AtLAST) science: Probing the transient and time-variable sky.
Open Res Eur

Division of Geological and Planetary Sciences, California Institute of Technology, Pasadena, California, 91125, USA.
The study of transient and variable events, including novae, active galactic nuclei, and black hole binaries, has historically been a fruitful path for elucidating the evolutionary mechanisms of our universe. The study of such events in the millimeter and submillimeter is, however, still in its infancy. Submillimeter observations probe a variety of materials, such as optically thick dust, which are hard to study in other wavelengths.

Background/objectives: Hidrocystomas, eccrine and apocrine, are rare cystic lesions that form benign tumors of the sweat glands. This study aimed to describe the clinical features of hidrocystomas and evaluate the role of non-invasive imaging techniques, including dermoscopy, Line-field Confocal Optical Coherence Tomography (LC-OCT), Reflectance Confocal Microscopy (RCM), and Ultra-High-Frequency Ultrasound (UHFUS), in their diagnosis.
Methods: In total, seven cases of hidrocystomas were collected from the Dermatologic Clinic of the University of Siena, Italy.
In situ spheroid formation in distant submillimetre-bright galaxies.

European Southern Observatory, Garching bei Munchen, Germany.
Most stars in today's Universe reside within spheroids, which are bulges of spiral galaxies and elliptical galaxies. Their formation is still an unsolved problem. Infrared/submillimetre-bright galaxies at high redshifts have long been suspected to be related to spheroid formation.

In this study, polyvinyl alcohol (PVA)-based ratiometric fluorescence nanofiber films with salicylamide (SA) as the response signal, rhodamine B (RhB) as the internal reference were prepared using electrospinning technique, and reducing their water solubility by glutaraldehyde (G) crosslinked. The RhB and SA were successfully immobilized in the PVA substrate. Moreover, RhB and SA improved the water resistance, water vapor barrier, and mechanical strength of the nanofiber films, among the PVA nanofiber films containing RhB and 400 mg SA (PVA/RhB/4SA-G) showed the best packaging performance.
