We present molecular dynamics simulations of the binary Kob-Andersen Lennard-Jones model, a model glass former, and consider the distributions of inherent energies and metabasins during aging. In addition to the typical protocol of performing a temperature jump from a high temperature to a low destination temperature, we consider the temporal evolution of the energy distributions after an "up-j...

The fundamental differences between the leading-order jump conditions, often assumed at a flame sheet in combustion theory, and the actual effect of a chemical reaction that satisfies Arrhenius kinetics with a finite activation temperature, need to be understood. These differences are “higher order” in terms of a large activation temperature analysis. However, they do provide a quantitative est...

We study the evolution of a trapped atomic cloud subject to a trapping frequency jump for two cases: stationary and moving centre of mass. In the first case, the frequency jump initiates oscillations in the cloud’s momentum and size. At certain times we find the temperature is significantly reduced. When the oscillation amplitude becomes large enough, local density increases induced by the anha...

FTIR difference spectroscopy has been used for the first time to investigate the kinetics of secondary structure formation during refolding. The refolding process of ribonuclease A (RNase A) as a model system was induced by applying a temperature-jump of 60 degrees. The temperature-jump was triggered by rapidly injecting a small volume of the thermally unfolded protein solution at 80 degrees C ...

Abstract—This paper presents a study on the effect of second-order slip and jump on forced convection through a long isothermally heated or cooled planar microchannel. The fully developed solutions of thermal flow fields are analytically obtained on the basis of the second-order Maxwell-Burnett slip and Smoluchowski jump boundary conditions. Results reveal that the second-order term in the Karn...

Vortex matter phases and phase transitions are investigated by means of Josephson plasma resonance in underdoped Bi2Sr2CaCu2O8+δ single crystals in a microwave frequency range between 19 and 70 GHz. Accompanied by the vortex lattice melting transition, a jump of the interlayer phase coherence extracted from the field dependence of the plasma frequency was observed. In the solid phase, the inter...

Microscale fluid dynamics has received intensive interest due to the emergence of microelectromechanical systems technology. When the mean free path of the gas is comparable to the channel’s characteristic dimension, the continuum assumption is no longer valid and velocity slip and temperature jump may occur at the duct walls. Slip flow heat transfer in annular microchannels has been examined. ...

Let L(t) be a Lévy flights process with a stability index α ∈ (0, 2), and U be an external multiwell potential. A jump-diffusion Z satisfying a stochastic differential equation dZ(t) = −U ′(Z(t−))dt+ σ(t)dL(t) describes an evolution of a Lévy particle of an ‘instant temperature’ σ(t) in an external force field. The temperature is supposed to decrease polynomially fast, i.e. σ(t) ≈ t for some θ ...

there is a substantial evidence that plyometric training significantly increases muscular strength and vertical jump. due to the vigorous nature of this type of training, however, there is a risk of incurring musculoskeletal injuries. therefore, conducting plyometric exercise programs in an aquatic environment might lead to significant improvements in vertical jump with possibly a lower risk of...
