Abstract On the basis of angular spectrum representation, a formalism describing paraxial beams propagating through an isotropic left-handed material (LHM) slab is presented. The treatment allows us to introduce the ideas of beam focusing and phase compensation by LHM slab. Because of the negative refractive index of LHM slab, the inverse Gouy phase shift and the negative Rayleigh length of par...

Integrated Wireless Networks (IWN) is an important area of today’s research because of its application in comprehensive services like battlefield surveillance, traffic avoidance and control systems, mobile health monitoring, biological detection and agricultural fields, structural health monitoring, Computer-assisted rehabilitation and therapy, tele-robotic surgery, etc. IWNs are employed to co...

An optimized design for the spanner shape regular hexagonal monopole (RHM) patch antennas has been reported to yield ultra wide band (UWB) impedance bandwidth. Impedance and radiation characteristics are presented and discussed. From the results, it has been observed that, the impedance bandwidth, defined by 10 dB return loss, can reach a value of 8.63GHz. A rectangular slit in the radiating pa...

Noble metal alloys are important in large-scale catalytic processes. Alloying facilitates fine-tuning of catalytic properties via synergistic interactions between metals. It also allows for dilution of scarce and expensive metals using comparatively earth-abundant metals. RhAg and RhAu are classically considered to be immiscible metals. We show here that stable RhM (M = Ag, Au) nanoparticles wi...

In the murine system, a number of cytokines (including interleukin-3 [IL-3], IL-4, and stem cell factor [SCF]) promote the growth of mast cells (MCs). However, so far little is known about factors controlling differentiation of human MCs. Recent data suggest that human MCs express receptors (R) for SCF. The aim of the present study was to investigate whether recombinant human (rh) SCF induces d...

Huntington’s Disease (HD) is a devastating neurodegenerative disorder that is caused by an expanded CAG trinucleotide repeat in the Huntingtin (HTT) gene. Transcriptional dysregulation in the human HD brain has been documented but is incompletely understood. Here we present a genome-wide analysis of mRNA expression in human prefrontal cortex from 20 HD and 49 neuropathologically normal controls...

Plants have the capacity to fix CO2 through photosynthesis. To reveal photosynthetic processes of Quercus acutissima Carruth. and variabilis Bl., their net rates were quantified during early peak growing seasons. evaluate forest efficiencies, light response curves Q. fitted by rectangular hyperbola model (RHM), non-rectangular (NHM), modified (Ye model). The results revealed following: (1) All ...

Stature determination aids the person identification during forensic investigation. The human hand research is current topic of interest among scientist, medicine experts and anthropologists. Based on sample size analysis, study involved consented 60 males females, age ranged from 18 to 55 years old. lengths measurements were made with Stadiometer Vernier Calipers for analysis. From each partic...

We investigated the ostracod assemblage structure in springs of a small lowland River Krąpiel valley. Environmental factors and potential ostracods as indicators spring type were analysed. The analysis involved spring, substrate, physicochemical parameters, river valley's hydrological status environmental factors. A total thirty species recorded. average count individuals sample amounted to 100...
