Consistency of Superspace Low Energy Equations of Motion of 4D Type II Superstring with Type II Sigma Model at Tree-Level [PDF]

Phys.Lett. B573 (2003) 217-226, 2003
We derive the torsion constraints and show the consistency of equations of motion of four-dimensional Type II supergravity in superspace, with Type II sigma model. This is achieved by coupling the four-dimensional compactified Type II Berkovits' superstring to an N=2 curved background and requiring that the sigma-model has superconformal invariance at ...

Generating controllable type-II Weyl points via periodic driving [PDF]

Phys. Rev. B 94, 235447 (2016), 2017
Type-II Weyl semimetals are a novel gapless topological phase of matter discovered recently in 2015. Similar to normal (type-I) Weyl semimetals, type-II Weyl semimetals consist of isolated band touching points. However, unlike type-I Weyl semimetals which have a linear energy dispersion around the band touching points forming a three dimensional (3D ...

A Novel Regulatory Mechanism of Type II Collagen Expression via a SOX9-dependent Enhancer in Intron 6*

Journal of Biological Chemistry, 2016
Type II collagen α1 is specific for cartilaginous tissues, and mutations in its gene are associated with skeletal diseases. Its expression has been shown to be dependent on SOX9, a master transcription factor required for chondrogenesis that binds to an ...

Site-specific mutagenesis of Escherichia coli asparaginase II. None of the three histidine residues is required for catalysis.

European Journal of Biochemistry, 1992
Site-specific mutagenesis was used to replace the three histidine residues of Escherichia coli asparaginase II (EcA2) with other amino acids. The following enzyme variants were studied: [H87A]EcA2, [H87L]EcA2, [H87K]EcA2, [H183L]EcA2 and [H197L]EcA2 ...

Flavour-Dependent Type II Leptogenesis [PDF]

Phys.Rev.D76:023512,2007, 2007
We reanalyse leptogenesis via the out-of-equilibrium decay of the lightest right-handed neutrino in type II seesaw scenarios, taking into account flavour-dependent effects. In the type II seesaw mechanism, in addition to the type I seesaw contribution, an additional direct mass term for the light neutrinos is present.

Mapping divalent metal ion binding sites in a group II intron by Mn(2+)- and Zn(2+)-induced site-specific RNA cleavage.

European Journal of Biochemistry, 2001
The function of group II introns depends on positively charged divalent metal ions that stabilize the ribozyme structure and may be directly involved in catalysis.

Herpes simplex virus‐1 infection alters microtubule‐associated protein Tau splicing and promotes Tau pathology in neural models of Alzheimer's disease

Brain Pathology, EarlyView.
HSV‐1 infection alters MAPT splicing and promotes Tau pathology in neural models of Alzheimer's disease. HSV‐1 infection in brain organoids and neuronal models increase 4R‐MAPT splicing and Tau hyperphosphorylation. HSV‐1 ICP27 is both necessary and sufficient for inducing these changes highlighting the potential role of HSV‐1 in Alzheimer's disease ...

CR Structures and Twisting Vacuum Spacetimes with Two Killing Vectors and Cosmological Constant: Type II and More Special [PDF]

Class. Quantum Grav. (2013) 30 115006, 2013
Based on the CR formalism of algebraically special spacetimes by Hill, Lewandowski and Nurowski, we derive a nonlinear system of two real ODEs, of which the general solution determines a twisting type II (or more special) vacuum spacetime with two Killing vectors (commuting or not) and at most seven real parameters in addition to the cosmological ...

Mammalian TatD DNase domain containing 1 (TATDN1) is a proteostasis‐responsive gene with roles in ventricular structure and neuromuscular function

The FEBS Journal, EarlyView.
Twin‐arginine translocation D (TatD) homologs are found across all kingdoms, with debated roles in DNA degradation and protein quality control in unicellular organisms. We characterize TATDN1, the mammalian TatD orthologue, as a proteostatic stress‐responsive cytosolic protein dispensable for DNA degradation.
