Charge Transport through Polyene Self-Assembled Monolayers from Multiscale Computer Simulations [PDF]

, 2008
We combine first-principles density-functional theory with matrix Green’s function calculations to predict the structures and charge transport characteristics of self-assembled monolayers (SAMs) of four classes of systems in contact with Au(111 ...

Dirac equation on a G_2 manifold [PDF]

, 2002
We find a large family of solutions to the Dirac equation on a manifold of $G_2$ holonomy asymptotic to a cone over $S^3 \times S^3$, including all radial solutions.

Enhanced fullerene–Au(111) coupling in (2√3 × 2√3)R30° superstructures with intermolecular interactions

Beilstein Journal of Nanotechnology, 2015
Disordered and uniform (2√3 × 2√3)R30° superstructures of fullerenes on the Au(111) surface have been studied using scanning tunneling microscopy and spectroscopy. It is shown that the deposition and growth process of a fullerene monolayer on the Au(111)

Stability of tenogenic secretomes optical density, colour, weight, TGF-b concentration and bacterial growth after 30-day storage under room or refrigerator temperature [PDF]

Scripta Medica
Background/Aim: The effectiveness and efficiency of tenogenic secretomes products are crucial to assess. Storage conditions affect both the distribution process and the stability of the tenogenic secretomes and their components.

Local methylthiolate adsorption geometry on Au(111) from photoemission core-level shifts [PDF]

, 2009
The local adsorption structure of methylthiolate in the ordered Au(111)-(√3×√3)R30° phase has been investigated using core-level-shift measurements of the surface and bulk components of the Au 4f7/2 photoelectron binding energy.

Phase transitions in two dimensions - the case of Sn adsorbed on Ge(111) surfaces [PDF]

, 1999
Accurate atomic coordinates of the room-temperature (root3xroot3)R30degree and low-temperature (3x3) phases of 1/3 ML Sn on Ge(111) have been established by grazing-incidence x-ray diffraction with synchrotron radiation.

Sex-Specific Autonomic Responses to Acute Resistance Exercise

Medicina, 2021
Background and Objectives: Acute resistance exercise (RE) reduces vagal modulation and increases sympathovagal balance, which increases the risk for arrythmias. Few studies have examined sex differences in autonomic modulation after acute RE. The purpose

Spontaneous Symmetry Breaking and Dynamic Phase Transition in Monolayer Silicene

, 2012
The (r3xr3)R30{\deg} honeycomb of silicene monolayer on Ag(111) was found to undergo a phase transition to two types of mirror-symmetric boundary-separated rhombic phases at temperatures below 40 K by scanning tunneling microscopy.

G(2) Holonomy Spaces from Invariant Three-Forms [PDF]

, 2001
We construct several new G(2) holonomy metrics that play an important role in recent studies of geometrical transitions in compactifications of M-theory to four dimensions.

Spatial-Temporal Seasonal Variability of Extreme Precipitation under Warming Climate in Pakistan

Atmosphere, 2023
Climate science has confirmed the alteration of the hydrological cycle attributed to global warming. This warming tendency affects the monsoon precipitation in Pakistan with an unprecedented intensity, causing severe flooding. Therefore, it is inevitable
