FEBS Open Bio, EarlyView.Stem cell‐based embryo models (SCBEMs) are valuable to study early developmental milestones. Matrigel, a basement membrane matrix, is a critical substrate used in various SCBEM protocols, but its role in driving stem cell lineage commitment is not clearly defined.

Polarized positron production at MeV electron accelerators [PDF]
arXiv, 2017 The Polarized Electrons for Polarized Positrons (PEPPo) experiment has demonstrated the efficient transfer of polarization from electrons to positrons produced by the bremsstrahlung radiation of a polarized electron beam in a high-$Z$ target. Positron polarization up to 82\% has been measured for an initial electron beam momentum of 8.19 MeV/$c ...

Time-dependent polarization states of high power, ultrashort laser pulses during atmospheric propagation [PDF]
, 2013 We investigate, through simulation, the evolution of polarization states during atmospheric propagation of high power, ultrashort laser pulses. A delayed rotational response model handling arbitrary, transverse polarization couples both the amplitude and phase of the polarization states.

LINC00323 variant is associated with increased risk of essential tremor
Annals of Clinical and Translational Neurology, EarlyView.Abstract Essential tremor (ET) is a common adult movement disorder, with accumulating evidence suggesting that genetic factors primarily account for ET risk. However, replication studies on the genetic variants have yielded inconsistent results. In our case–control study, we show that the LINC00323 variant, identified in a European GWAS study, is ...

Broadband spectral shaping using nematic liquid crystal
Results in Physics, 2019 We demonstrate what is, to our knowledge, the first implementation of nematic liquid crystal (LC) for spectral shaping of broadband light fields. A LC cell of several microns thickness is placed between a polarizer and an analyzer.

Polar actions on the complex hyperbolic plane [PDF]
arXiv, 2011 We classify the polar actions on the complex hyperbolic plane up to orbit equivalence. Apart from the trivial and transitive polar actions, there are five polar actions of cohomogeneity one and four polar actions of cohomogeneity two.

Metabolic Consequences of Rheumatoid Arthritis
Arthritis Care &Research, EarlyView.Patients with rheumatoid arthritis (RA) may have metabolic disruption, which can contribute to adverse long‐term outcomes, for multiple reasons. Patients with RA appear to have a higher risk of sarcopenia, type 1 and type 2 diabetes mellitus, metabolic syndrome, and hypertension. Systemic inflammation in RA can cause a “lipid paradox,” with reduced low‐
