in the present paper, resonant frequencies and modes of a three-atom photonic molecule and a photonic crystal placed within a cavity are numerically calculated. first, governing formulation in transverse electric field mode (te) is obtained using maxwell equations. then, an algorithm based on a finite difference scheme and matrix algebra is presented. the algorithm is then implemented in a comp...

This study presents experimental results performed on samples of Eutectic solder material (63 wt. % Sn 37 wt. % Pb). The tests were performed at high strain rates using Split Hopkinson’s Pressure Bar (SHPB). The strain rates were in the range of 400s -1 to 1300s -1 . Heating unit was added to conventional SHPB to vary initial sample temperature conditions. Tests were conducted at room temperatu...

Transition-metal dichalcogenides (TMDs) nanostructures including nanotubes and monolayers have attracted great interests in materials science, chemistry to condensed matter physics. We present an interesting study of the vibration modes in multi-walled tungsten sulfide (WS2) nanotubes prepared via sulfurizing tungsten oxide (WO3) nanowires which are investigated by confocal micro-Raman spectros...

INTRODUCTION Since M-mode measurements can assess deformation of specific regions of the left ventricle, we hypothesized that M-mode measurements like M-mode apical systolic excursion (MMASE) and mitral annular plane systolic excursion (MAPSE) may be correlated with left ventricular longitudinal strain (LVLS). METHODS All subjects of the study underwent a full echocardiographic evaluation and...

Nitrogen-vacancy (NV) centers can couple to confined phonons in diamond mechanical resonators via the effect of lattice strain on their energy levels. Access to the strong spin-phonon coupling regime with this system requires resonators with nanoscale dimensions in order to overcome the weak strain response of the NV ground-state spin sublevels. In this work, we incorporate photostable NVs in d...

Cooling a mechanical resonator mode to a sub-thermal state has been a long-standing challenge in physics. This pursuit has recently found traction in the field of optomechanics in which a mechanical mode is coupled to an optical cavity. An alternate method is to couple the resonator to a well-controlled two-level system. Here we propose a protocol to dissipatively cool a room temperature mechan...

You are studying the mode of inheritance of eye color in flies. You have isolated four true-breeding mutant strains with green eyes . In contrast, wild-type flies have red eyes . In your Strains box in StarGenetics you will find 1) homozygous mutant male and female flies for each mutant strain and 2) homozygous wild-type male and female flies. In each of the four mutant strains, the mode of inh...

In this paper we demonstrate a simple temperature and strain discriminating sensor based on a single fibre Bragg grating inscribed by a femtosecond laser via the point-by-point technique. These gratings exhibit strong and extensive cladding mode structures and by simultaneously monitoring both the Bragg wavelength and a cladding mode spaced by ~ 40 nm from the Bragg peak, as a function of both ...

A draft genome sequence of Rathayibacter sp. strain VKM Ac-2630 was derived using Ion Torrent sequencing technology. The genome size of this strain is 3.88 Mb, with an average G+C content of 72.0%. Genomic evidence of an aerobic mode of respiration and a heterotrophic lifestyle of this bacterium was obtained.

To date, only one marine sponge pathogen (Pseudoalteromonas sp. strain NW 4327) has fulfilled Koch's postulates. We report the 4.48-Mbp draft genome sequence of this strain, which is pathogenic to the Great Barrier Reef sponge Rhopaloeides odorabile. The sequence provides valuable information on sponge-pathogen interactions, including the mode of transmission and associated virulence factors.
