Feasibility Study for Application of Digitized Henize Mt. Wilson Michigan Southern Sky Hα$$ \boldsymbol{\alpha} $$ Survey Low‐Dispersive Spectral Plates for Searches for Anomalous and Highly Redshifted Objects

open access: yesAstronomische Nachrichten, EarlyView.
ABSTRACT The goal of this study is to confirm the feasibility of the use of digitized low dispersive MtWilson Michigan Southern Sky Hα$$ \alpha $$ survey astronomical photographic plates for modern astrophysical research. The detection of highly redshifted objects, such as early galaxies and quasars, is fundamental to understanding the universe's ...

The ORCA‐TWIN qCMOS Experiment I. Science Case and Commissioning at Calar Alto Observatory

open access: yesAstronomische Nachrichten, EarlyView.
ABSTRACT We describe a pilot study to explore a new generation of fast and low noise CMOS image sensors for time domain astronomy, using two remote telescopes with a baseline of 1635 km. The experiment involves direct imaging with novel qCMOS image sensor technology that combines fast readout with sub‐electron readout noise.

Color Photometric Stereo Using Multi-Band Camera Constrained by Median Filter and Occluding Boundary

open access: yesJournal of Imaging, 2019
One of the main problems faced by the photometric stereo method is that several measurements are required, as this method needs illumination from light sources from different directions.

Speckle Observations With PISCO in Calern (France): III. Astrometric Measurements of Visual Double Stars in 2019 and New or Revised Orbits for STT531 AB, STT77 AB, STF1338 AB, COU1746, STT260, A1109 AB, HU1291, and A632 AB

open access: yesAstronomische Nachrichten, EarlyView.
ABSTRACT We present relative astrometric measurements of visual double stars, made in 2019 with the speckle camera PISCO at the 1‐m Epsilon telescope of the C2PU facility (Observatoire de la Côte d'Azur, Calern site). Our observing list contains orbital couples as well as double stars whose motion is still uncertain.

Photometry of Variable Stars, and System Transformability Over Long Time Intervals

open access: yesOpen Astronomy, 2003
The fundamental problem of long-term photometric monitoring of variable stars and of multi-wavelength photometric campaigns is the problem of bringing the data to a common standard.

Revisiting Variable Stars Toward the Globular Cluster NGC 6496 With ATLAS and Gaia Photometry

open access: yesAstronomische Nachrichten, EarlyView.
ABSTRACT We revisit 13 variable stars in the field of the metal‐rich globular cluster NGC 6496, discovered by Abbas et al. (2015; Astronomical Journal 149:40) (hereafter referred to as “MA15”) via time‐series data, spanning 2 years. We improve upon the MA15 characterization of the variables using ATLAS time‐series photometry data, spanning 8 years, in ...

Possible therapeutic repositioning of valproic acid: From epileptic seizures to acute kidney injury

open access: yesBritish Journal of Clinical Pharmacology, EarlyView.
Valproic acid, an anticonvulsant, may be repositioned to prevent acute kidney injury due to ischemia followed by reperfusion. It preserves renal functions, electrolyte homeostasis and active sodium transport in kidney tubules, and blocks the onset of hypertension.

Status and future of recombinant adeno‐associated virus vector manufacturing

open access: yesBiotechnology Progress, EarlyView.
Abstract Sixty years of adeno‐associated virus (AAV) research illustrates a trajectory marked by basic science exploration, iterative innovation, persistent challenges, a number of clinical setbacks, as well as commercial therapeutic triumphs. This continual evolution has led to recombinant AAV (rAAV) becoming a cornerstone of modern gene therapy ...

High‐throughput development and scale‐up of recombinant adeno‐associated virus 5 anion‐exchange chromatography for high‐purity capsid separation

open access: yesBiotechnology Progress, EarlyView.
High‐throughput anion‐exchange chromatography process development enables scalable purification of high‐purity recombinant adeno‐associated virus capsids. Abstract Recombinant adeno‐associated virus (rAAV) production commonly yields a high proportion of empty and partially filled capsids, necessitating downstream purification to enrich full capsids ...

Effects of Dehulling and Extrusion‐Cooking on the Nutritional and Physicochemical Properties of Navy Bean (Phaseolus vulgaris L.) Flours

open access: yesChemFoodChem, EarlyView.
Dehulling combined with twin‐screw extrusion improves the nutritional and functional properties of steam treated navy beans. Protein digestibility increases while phytic acid is reduced by 43% and trypsin inhibitors are inactivated. Enhanced expansion, solubility, and sensory quality highlight the potential of dehulled bean flours for developing ...
