Bifurcations of composite-cavity modes in multi-stripe laser arrays [PDF]
, 2008 We consider a semiconductor laser device, where the active region consists of parallel stripes in the longitudinal direction. In the composite cavity model, the stripes are coupled via the transversal modes of the entire compound laser device.

Translophagy—A potential link between autophagy impairment and translational errors
FEBS Letters, EarlyView.Neurodegenerative diseases are characterised by the accumulation of abnormal proteins and protein aggregates, but their origin often remains unknown. We propose that selective autophagy removes damaged protein‐making machinery, preventing errors during protein synthesis.

FEBS Letters, EarlyView.Mycobacterial 3‐methylcrotonyl‐CoA carboxylase uses a mobile biotin‐carrying domain to shuttle a carboxyl group between two catalytic sites, enabling carboxylation of 3‐methylcrotonyl‐CoA during leucine breakdown. Cryo‐electron microscopy captures the carrier at both sites and reveals an inward loop movement that may prevent futile rebinding to the ...

Single-particle spectra and Fermi surface near a stripe instability
, 1999 We analyze the single-particle spectra of a model for electrons coupled to critical charge and spin fluctuations near a stripe instability. We compare our results with ARPES experiments on the cuprate superconductors near optimum doping and discuss the ...

FEBS Letters, EarlyView.Vacuolar H+‐ATPase (V‐ATPase) is a multisubunit rotary proton pump that acidifies intracellular compartments. Using elastic network models, we identified conserved hinge residues that govern its large‐scale functional motions. We show that intrinsically encoded ‘soft modes’ drive critical functional transitions, including rotary catalysis and ...

Magnetization, Charge Transport , and Stripe Phases in Nd5/3Sr1/3NiO4+δ Single Crystal [PDF]
, 2006 Stripe phases, in which doped charges are localized along domain walls between antiferromagnetic insulating regions, provide a framework for the electronic structure of doped antiferromagnets such as the superconducting layered copper-oxides.

Exact Classification with Two-Layered Perceptrons [PDF]
, 1992 We study the capabilities of two-layered perceptrons for classifying exactly a given subset. Both necessary and sufficient conditions are derived for subsets to be exactly classifiable with two-layered perceptrons that use the hard-limiting response ...

Molecular Oncology, EarlyView.This study identifies somatostatin receptor 4 (Sstr4) as a critical tumor suppressor against skin and head/neck cancers (HNSCC, cSCC, and BCC). The loss of Sstr4 removes a check on cell growth, causing hyperactivation of the MAPK‐ERK signaling pathway (↑).

The stripe-liquid phase in cuprates and nickelates
, 2002 It is well established that doped 2D antiferromagnets such as layered nickelates and certain cuprates can exhibit an ordered phase in which charge carriers are segregated to periodically-spaced domain walls separating antiferromagnetic domains.

Molecular Oncology, EarlyView.Extracellular vesicle (EV) lipidomic profiling of plasma and ascites from patients with high‐grade serous ovarian cancer and of ovarian cancer cell lines reveals enrichment of triglycerides (TGs), diacylglycerols (DGs), phosphatidylcholine (PCs), sphingomyelins (SMs), reflecting tumor metabolic reprogramming.
