High performance micromachining of sapphire by laser induced plasma assisted ablation (LIPAA) using GHz burst mode femtosecond pulses

open access: yesOpto-Electronic Science
GHz burst-mode femtosecond (fs) laser, which emits a series of pulse trains with extremely short intervals of several hundred picoseconds, provides distinct characteristics in materials processing as compared with the conventional irradiation scheme of ...

Determining the maximum permissible content of recycled asphalt pavement stockpile in plant hot-mix recycled asphalt mixtures considering homogeneity: A case study in China

open access: yesCase Studies in Construction Materials, 2022
In engineering practice, recycled asphalt pavement (RAP) is often obtained from various sources and is mixed and stockpiled in a disorderly manner, which is defined as a hybrid RAP.

Insight into Resonant Activation in Discrete Systems

open access: yes, 2004
The resonant activation phenomenon (RAP) in a discrete system is studied using the master equation formalism. We show that the RAP corresponds to a non-monotonic behavior of the frequency dependent first passage time probability density function (pdf ...

Transport of ultracold atoms between concentric traps via spatial adiabatic passage [PDF]

open access: yes, 2016
Spatial adiabatic passage processes for ultracold atoms trapped in tunnel-coupled cylindrically symmetric concentric potentials are investigated. Specifically, we discuss the matter-wave analogue of the rapid adiabatic passage (RAP) technique for a high ...

Mapping the evolution of mitochondrial complex I through structural variation

open access: yesFEBS Letters, EarlyView.
Respiratory complex I (CI) is crucial for bioenergetic metabolism in many prokaryotes and eukaryotes. It is composed of a conserved set of core subunits and additional accessory subunits that vary depending on the organism. Here, we categorize CI subunits from available structures to map the evolution of CI across eukaryotes. Respiratory complex I (CI)

Random Access for Underwater Acoustic Cellular Systems

open access: yesSensors, 2018
In this paper, a random access preamble (RAP) design technique for underwater acoustic cellular systems is proposed. After showing that the conventional RAP used in long term evolution (LTE) systems is not appropriate for underwater acoustic cellular ...

The classification and reutilisation of recycled asphalt pavement binder: Norwegian case study

open access: yesCase Studies in Construction Materials, 2022
With increased demand of asphalt pavement and limited binder and aggregate supply, the reutilisation of Recycled Asphalt Pavement (RAP) has gained more attention in pavement engineering from the environmental, sustainable, and economic views.

Throwin' words at U : a lyrical analysis of MC Lyte's rap texts : a thesis presented in partial fulfilment of the requirements for the degree of Master of Arts in English at Massey University, Palmerston North, New Zealand [PDF]

open access: yes, 2001
Recently, rap music has become a prominent musical genre and is possibly one of the most popular and influential forms of African-American music of the 1980s and 1990s (Erlewine et al 921).
