Novel Atmospheric Monitoring for the H.E.S.S. site and its Industrial Applications [PDF]

, 2009
This thesis concerns the atmospheric monitoring instrumentation for the H.E.S.S. (High Energy Stereoscopic System) gamma-ray telescope site and the adaptation of such instruments for commercial use. The effect of the atmosphere on the H.E.S.S. telescopes'

Submillimetre multicolour photometry of astronomical sources

, 1978
Techniques and instrumentation for submillimeter photometry are discussed. The described photometer is designed to work over the wavelength range 2 mm to 300 microns and uses bandpass filters to isolate the windows at 1200, 850-750, and 450-350 microns ...

Complement C3 mediates adolescent social isolation‐induced hippocampal synaptic deficits and sex‐specific emotional dysfunction

Interdisciplinary Medicine, EarlyView.
Adolescent social isolation disrupts hippocampal function and exacerbates emotional symptoms, with sex‐specific patterns, as shown by human studies. In mice, social isolation decreased hippocampal synaptic density and calcium signaling, upregulated complement proteins, and activated complement‐mediated microglial synaptic phagocytosis.

FORECASTOR. I. Finding Optics Requirements and Exposure Times for the Cosmological Advanced Survey Telescope for Optical and UV Research Mission

The Astronomical Journal
The Cosmological Advanced Survey Telescope for Optical and ultraviolet Research (CASTOR) is a proposed Canadian-led 1 m class space telescope that will carry out ultraviolet and blue optical wide-field imaging, spectroscopy, and photometry.

Experimental Study of PWM-Controlled Emission From a Large-Aperture VCSEL

IEEE Photonics Journal
This study demonstrates the use of pulse-width modulation (PWM) for mode selection in a large-aperture vertical-cavity surface-emitting laser (VCSEL). Experimental results reveal that driving the device with 1 kHz PWM pulses maintains a stable far-field ...

PSF reconstruction for AO photometry and astrometry [PDF]

, 2015
Extracting accurate photometry (and astrometry) from images taken with adaptive optics assisted instruments isparticularly challenging. Current post-processing tools are not prepared to achieve high accuracy from AO data,especially in limiting cases of ...

Iloperidone treatment mitigates the Juvenile Huntington's Disease phenotype possibly via Sigma‐1 Receptor Modulation

The FEBS Journal, EarlyView.
We investigated the potential of iloperidone as an activator of Sigma‐1 receptor (S1R) neuroprotective function in juvenile Huntington's disease (jHD). We tested iloperidone on cortical neurons differentiated from patient‐derived iPSCs, demonstrating that it acts as a S1R agonist, decreasing apoptosis, huntingtin aggregation, and oxidative stress ...

Long‐read sequencing‐based atlas of tissue‐specific expression of DNM1L transcript variants

The FEBS Journal, EarlyView.
Targeted long‐read sequencing resolves full‐length DNM1L (Drp1) isoforms and reveals conserved, tissue‐specific expression patterns across human and mouse tissues. Functional assays show that Drp1 isoforms differ in their ability to drive mitochondrial fission, independent of abundance, with specific exons modulating activity.
