Using density functional simulations, within the generalized gradient approximation and projectoraugmented wave method, we study structures and energetics of CaSiO3 perovskite in the pressure range of the Earth’s lower mantle (0–150 GPa). At zero Kelvin temperature the cubic ðPm 3mÞ CaSiO3 perovskite structure is unstable in the whole pressure range, at low pressures the orthorhombic (Pnam) str...

Sr$_2$CuO$_2$Cl$_2$ (SCOC) is a model undoped cuprate with $I4/mmm$ crystallographic symmetry, and simple magnetic space group $C_Amca$ associated point $mmm1'$. However, recent second harmonic spectroscopy in the antiferromagnetic phase has challenged this picture, suggesting instead $4/mm'm'$ that co-exists antiferromagnetism breaks two orthogonal mirror planes containing tetragonal $c$-axis....

BACKGROUND Incremental palmar stimulation of the median nerve sensory conduction at the wrist, the "inching test", provides an assessment with reference to segments proximal and distal to the entrapment. This study used high-resolution ultrasonography (US) to measure the median nerve's cross-section areas (CSAs) like the "inching test" and to correlate with the nerve conduction study (NCS) seve...

Abstract Superconducting high entropy alloys (HEAs) are new members of disordered superconductors. We report the synthesis and investigation a superconducting alloy Mo 0.11 W V Re 0.34 B 0.33 (MWVRB). It crystallized in tetragonal CuAl 2 crystal structure with space group (I4/ mcm ). Comprehensive transport, magnetization heat capacity measurements confirmed bulk type-II superconductivity havin...

I n 2013 during a 20 month long shutdown of the LHC the Pixel Detector of the ATLAS Experiment at CERN will be upgraded by inserting a fourth innermost layer between the beam pipe and the current detector. This so called Insertable B-Layer (IBL) will be constructed with 448 of the new FE-I4 chips to handle the readout of the about 12 million pixels provided by the sensors of this layer. The imp...

partial fulfillment of the requirements for the degree of Master of Science. Cahnite is one of the few crystals which had been assigned to crystal class 4. A precession study showed that its diffraction sphol is 4/m I-/-, which contains space groups I4, I4E, and14/. Because of the known 4 morphology, it must be assigned to space group I4. The unit cell, whose dimensions are a = 7.11A, o = 6.201...

The cingulum bundle (CB) connects gray matter structures of the limbic system and as such has been implicated in the etiology of schizophrenia. There is growing evidence to suggest that the CB is actually comprised of a conglomeration of discrete sub-connections. The present study aimed to use Diffusion Tensor tractography to subdivide the CB into its constituent sub-connections, and to investi...
