In this paper a straightforward high energy expansion is discussed and applied to the problem of radiation from an extended target. In particular, we discuss bremsstrahlung from an electron-pulse collision. A full quantum treatment of the power spectrum and the average energy loss is given. Scaling laws that smoothly join the quantum regime to the classical limit are derived. Submitted to Physi...

Massive gravity previously constructed as the spin-2 quantum gauge theory is studied in the classical limit. The vector graviton field v which does not decouple in the limit of vanishing graviton mass gives rise to a modification of general relativity. The modified Schwarzschild solution contains a contribution from the v-field which can be interpreted as the dark matter mass density. We calcul...

Land management intrinsically influences the distribution of animals and can consequently alter the potential for density-dependent processes to act within populations. For declining species, high densities of breeding territories are typically considered to represent productive populations. However, as density-dependent effects of food limitation or predator pressure may occur (especially when...

A number of neurological disorders such as epidural hematoma can cause compression of cerebral cortex. We here tested the hypothesis that sustained compression of primary somatosensory cortex may affect stellate neurons and thalamocortical afferent (TCA) fibers. A rat model with barrel cortex subjected to bead epidural compression was used. Golgi-Cox staining analyses showed the shrinkage of de...

BACKGROUND The clinical application of stem cell therapy for myocardial infarction will require the development of methods to monitor treatment and pre-clinical assessment in a large animal model, to determine its effectiveness and the optimum cell population, route of delivery, timing, and flow milieu. OBJECTIVES To establish a model for a) in vivo tracking to monitor cell engraftment after ...

Metal matrix syntactic foams have been fabricated via counter-gravity infiltration of a packed bed of recycled expanded glass particles (EG) with A356 aluminum alloy. Particle shrinkage was studied and has been utilized to increase the particles' strength and tailor the mechanical properties of the expanded glass/metal syntactic foam (EG-MSF). The crushing strength of particles could be doubled...

We develop new statistical methods for estimating functional connectivity between components of a multivariate time series and for testing differences in functional connectivity across experimental conditions. Here, we characterize functional connectivity by partial coherence, which identifies the frequency band (or bands) that drives the direct linear association between any pair of components...

Soft soil problems and increased production of fuel waste have emerged due to world population growth. These two are prompting engineers introduce new methods using stabilize the soil. Previous research has shown clear sustained improvements in properties palm oil ash (POFA) when mixed with a calcium-based binder such as NaCl, lime or cement. The use stabilizing agent can reduce economic associ...

The early age shrinkage is responsible for the early age cracking of concrete. It is very critical for durability of concrete. The change in volume of concrete due to evaporation of water or dehydration process is known as shrinkage. To reduce the early age shrinkage utilized the supplementary cementitious material (SCM) in concrete. In present research industrial and agricultural waste byprodu...

Microplastic (MP) contamination is an urgent environmental issue to address. Fibrous microplastics (FMPs) are the principal MP type in air and have already been found human stool lung tissues. FMPs generated from lifecycle of synthetic blended textiles expected increase due fast fashion. Among textile processes, finishing fabrics estimated generate 5000 t/year waste fibers Italy, including FMPs...
