Nucleon structure with two flavors of dynamical domain-wall fermions

, 2008
We present a numerical lattice quantum chromodynamics calculation of isovector form factors and the first few moments of the isovector structure functions of the nucleon.

An upstream open reading frame regulates expression of the mitochondrial protein Slm35 and mitophagy flux

FEBS Letters, EarlyView.
This study reveals how the mitochondrial protein Slm35 is regulated in Saccharomyces cerevisiae. The authors identify stress‐responsive DNA elements and two upstream open reading frames (uORFs) in the 5′ untranslated region of SLM35. One uORF restricts translation, and its mutation increases Slm35 protein levels and mitophagy.

Functional insights into the photoactive yellow protein family from homologs, multidomain proteins, and inferred pyp operons

Journal of Bacteriology
Photoactive Yellow Protein (PYP) is a model system for functional protein dynamics and a prototype of the PAS domain superfamily. It is a bacterial photoreceptor that triggers a range of responses in different bacteria: phototaxis, biosynthesis of photo ...

Domain structure regularization in monocrystalline barium hexaferrite

Semiconductor Physics, Quantum Electronics & Optoelectronics, 2018
Conditions for regular domain structure formation in a monocrystalline barium hexaferrite plate have been studied experimentally. The purpose of the work was to develop a simple and, at the same time, an effective method of regularizing the cylindrical ...

Field sweep rate dependence of magnetic domain patterns: Numerical simulations for a simple Ising-like model

, 2007
We study magnetic domain patterns in ferromagnetic thin films by numerical simulations for a simple Ising-like model. Magnetic domain patterns after quench demonstrate various types of patterns depending on the field sweep rate and parameters of the ...

mTOR kinase structure, mechanism and regulation by the rapamycin-binding domain

Nature, 2013
The mammalian target of rapamycin (mTOR), a phosphoinositide 3-kinase-related protein kinase, controls cell growth in response to nutrients and growth factors and is frequently deregulated in cancer.

In situ molecular organization and heterogeneity of the Legionella Dot/Icm T4SS

FEBS Letters, EarlyView.
We present a nearly complete in situ model of the Legionella Dot/Icm type IV secretion system, revealing its central secretion channel and identifying new components. Using cryo‐electron tomography with AI‐based modeling, our work highlights the structure, variability, and mechanism of this complex nanomachine, advancing understanding of bacterial ...

Heterotic domain wall solutions and SU(3) structure manifolds

, 2013
We examine compactifications of heterotic string theory on manifolds with SU(3) structure. In particular, we study N = 1/2 domain wall solutions which correspond to the perturbative vacua of the 4D, N =1 supersymmetric theories associated to these ...

Domain structure and domain-domain interactions of recombinant tissue plasminogen activator

Journal of Biological Chemistry, 1991
The melting of recombinant tissue plasminogen activator (rtPA) has been investigated by differential scanning calorimetry and fluorescence spectroscopy. At neutral pH, rtPA melts with only partial reversibility in a single sharp peak that can be deconvoluted into four transitions.
