Phase Retrieval via Model-Free Power Flow Jacobian Recovery [PDF]
arXiv, 2023 Phase retrieval is a prevalent problem in digital signal processing and experimental physics that consists of estimating a complex signal from magnitude measurements. This paper expands the classical phase retrieval framework to electric power systems with unknown network models and limited access to observations of voltage magnitudes, active power ...

The Saccharomyces cerevisiae amino acid transporter Lyp1 has a broad substrate spectrum
FEBS Letters, EarlyView.In Saccharomyces cerevisiae, Yeast Amino acid Transporter family members mediate the import of amino acids, ranging from substrate specialists to generalists. Here, we show that the specialist transporter, Lyp1, has a broader substrate spectrum than previously described, with affinity constants spanning from micromolar to millimolar.

FEBS Letters, EarlyView.In lymphoid organs, antigen recognition and B cell receptor signaling rely on integrins and the cytoskeleton. Integrins act as mechanoreceptors, couple B cell receptor activation to cytoskeletal remodeling, and support immune synapse formation as well as antigen extraction.

Near opposition photometry of comet C/2007 N3 (Lulin) [PDF]
, 2010 Observations on comet C/2007 N3 (Lulin) were made at phase angles close to opposition ($1.7^{\circ}$ - $10^{\circ}$). Photometric observations were carried out during 2009 February 24-28, in the IHW blue and red continuum and $R$ broad band using photo-polarimeter mounted on the 1.2m telescope at Mt Abu IR Observatory.

Clinical heterogeneity in a family with flail arm syndrome and review of hnRNPA1‐related spectrum
Annals of Clinical and Translational Neurology, Volume 9, Issue 12, Page 1910-1917, December 2022., 2022 Abstract Objective Flail arm syndrome (FAS) is one of the atypical subtypes of amyotrophic lateral sclerosis (ALS). Mutations in hnRNPA1 encoding heterogeneous nuclear ribonucleoprotein (hnRNP) A1 are a rare genetic cause of ALS. Herein, marked clinical heterogeneity of FAS in a pedigree with a known hnRNPA1 variant was described to raise early ...
