Edge states in Gravity and Black Hole Physics

, 1994
We show in the context of Einstein gravity that the removal of a spatial region leads to the appearance of an infinite set of observables and their associated edge states localized at its boundary.

Role of 1D edge in the elasticity and fracture of h-BN doped graphene nanoribbons

Materials Research Express
Recent achievement of BN-graphene alloy material has enabled the potential of bandgap tuning through both sub-10 nm width control and BN concentration variation.

pH‐mediated activation of the lysosomal arginine sensor SLC38A9

FEBS Letters, EarlyView.
Cells monitor nutrient levels via the lysosomal transporter SLC38A9 to activate the mechanistic target of rapamycin complex 1 (mTORC1). This study reveals that SLC38A9 function is regulated by pH. We identified histidine 544 as a critical pH sensor that undergoes conformational changes to control amino acid efflux from lysosomes; therefore, it ...

Dynamics of Spin Relaxation near the Edge of Two-Dimensional Electron Gas

, 2004
We report calculations of spin relaxation dynamics of two-dimensional electron gas with spin-orbit interaction at the edge region. It is found that the relaxation of spin polarization near the edge is more slow than relaxation in the bulk.

Effects of landscape fragmentation at a fine scale on Mediterranean mountain grassland plant diversity

Ecosphere
European mountain grasslands are affected by abandonment and are being colonized by shrubs and forest. Grassland fragmentation is caused when the forest matrix grows, and surrounding grassland is split into fragments.

Study of Stress-Strain State of Long Cracked Multi-Modulus Strip in Bending in Relation to Crack Formation in Tensile Zone of Concrete

Structural Mechanics of Engineering Constructions and Buildings
The problem of strength analysis of a multi-modulus strip, in contradiction to the existing standpoint of essential nonlinearity, may be formulated as a linear problem for a two-layer strip.

Modeling Yields Response to Shading in the Field-to-Forest Transition Zones in Heterogeneous Landscapes

Agriculture, 2019
In crop modeling and yield predictions, the heterogeneity of agricultural landscapes is usually not accounted for. This heterogeneity often arises from landscape elements like forests, hedges, or single trees and shrubs that cast shadows.

Residual tail twisting in ascidian larvae is stabilized by asymmetric myofibrils that resist bilateral symmetry restoration

FEBS Letters, EarlyView.
Ascidian Ciona larvae initially show strong clockwise tail twisting, which is largely corrected during development. However, a small residual twist remains. This study shows that organized helical myofibrils in tail muscles mechanically stabilize this residual asymmetry, preventing complete restoration of bilateral symmetry and revealing how embryos ...

Effects of leading-edge devices on the low-speed aerodynamic characteristics of a highly-swept arrow-wing [PDF]

An investigation was conducted in the Texas A&M University 7 by 10 foot Low Speed Wind Tunnel to provide a direct comparison of the effect of several leading edge devices on the aerodynamic performance of a highly swept wing configuration.
