Quantum Stress Tensor Fluctuations and their Physical Effects

, 2007
We summarize several aspects of recent work on quantum stress tensor fluctuations and their role in driving fluctuations of the gravitational field. The role of correlations and anticorrelations is emphasized.

Glucose priming effect on microbial intercellular metabolic flux diversity in a marine intertidal sediment.

PLoS ONE
Microbial communities inhabiting intertidal sediment show diverse metabolisms to adapt to hydrodynamic conditions. However, the priming effect of exogenous organic matter on microbial metabolic fluxes remains poorly understood.

Spatiotemporal variation of vegetation carbon stocks and its driving factors in the Urumqi River Basin

Ecological Indicators
Vegetation carbon (VC) is a key indicator of the carbon cycle in terrestrial ecosystems, and the study of spatial and temporal changes in VC stocks at the watershed scale can better reveal the impacts of natural and human activities on VC stocks in ...

Thermodynamic curvature measures interactions

, 2010
Thermodynamic fluctuation theory originated with Einstein who inverted the relation $S=k_B\ln\Omega$ to express the number of states in terms of entropy: $\Omega= \exp(S/k_B)$.

Local orientations of fluctuating fluid interfaces

, 2005
Thermal fluctuations cause the local normal vectors of fluid interfaces to deviate from the vertical direction defined by the flat mean interface position.

Enhancement of noncontact friction between closely spaced bodies by two-dimensional systems [PDF]

, 2006
. We consider the effect of an external bias voltage and the spatial variation of the surface potential, on the damping of cantilever vibrations. The electrostatic friction is due to energy losses in the sample created by the electromagnetic field from ...

An experimental study of the sources of fluctuating pressure loads beneath swept shock/boundary-layer interactions [PDF]

An experimental research program providing basic knowledge and establishing a database on the fluctuating pressure loads produced on aerodynamic surfaces beneath three dimensional shock wave/boundary layer interactions is described. Such loads constitute

Implications of Charge Ordering for Single-Particle Properties of High-Tc Superconductors

, 1996
The consequences of disordered charge stripes and antiphase spin domains for the properties of the high-temperature superconductors are studied. We focus on angle-resolved photoemission spectroscopy and optical conductivity, and show that the many ...

Event-by-event hydrodynamics and elliptic flow from fluctuating initial state

, 2011
We develop a framework for event-by-event ideal hydrodynamics to study the differential elliptic flow which is measured at different centralities in Au+Au collisions at Relativistic Heavy Ion Collider (RHIC).
