A closed-form inversion charge-based long-channel drain current model is developed for a symmetrically driven, lightly doped Symmetric Double-Gate MOSFET (SDGFET). It is based on the drift-diffusion transport mechanism and considers velocity saturation using the Caughey-Thomas model with exponent n=2, vertical field mobility degradation and body doping. It is valid in subthreshold as well as ab...

We present an ARPES study of the surface states of Ru2Sn3, a new type of a strong 3D topological insulator (TI). In contrast to currently known 3D TIs, which display two-dimensional Dirac cones with linear isotropic dispersions crossing through one point in the surface Brillouin Zone (SBZ), the surface states on Ru2Sn3 are highly anisotropic, displaying an almost flat dispersion along certain h...

PURPOSE To propose a 3D quantitative high-resolution T1 mapping technique, called 3D SASHA (saturation-recovery single-shot acquisition), which combines a saturation recovery pulse with 1D-navigator-based-respiratory motion compensation to acquire the whole volume of the heart in free breathing. The sequence was tested and validated both in a T1 phantom and in healthy subjects. MATERIALS AND ...

INTRODUCTION The motion of the distal syndesmosis correlates highly with the instability, while an accurate kinematic description of the distal tibiofibular joint during normal gait has not previously been presented. MATERIAL AND METHODS Sixteen healthy syndesmoses of sixteen living subjects (8 male and 8 female) were studied during stance phase of the normal gait. Data of CT scanning were co...

bh_tomo is an open source borehole georadar data processing and ray-based 2D tomography software package developed at the École Polytechnique of Montréal. bh_tomo runs under Matlab version 7.0 and above, and is therefore portable between computer operating systems supported by Matlab. To perform the tomographic inversions, bh_tomo includes an implementation of the classical LSQR algorithm, as w...

The paper presents an innovative way of a simulation of multiconductor transmission line (MTL) circuits which combines the Laplace transformations in one and in two variables. This approach enables to compute both nodal voltages (branch currents) in lumped-element parts of a circuit and voltage (current) waves distributions along MTLs’ wires effectively. The first one is performed by the numeri...

INTRODUCTION Assessing myocardial viability in patients with coronary artery disease and left ventricular dysfunction can be critical to determine which patients might benefit from revascularization [1]. Delayed-enhancement MR imaging (DE-MRI) has shown promise in distinguishing healthy myocardium from infarcted myocardium since infarcted myocardium exhibits higher signal than normal myocardium...

Gray matter (GM) images with high spatial resolution are obtained at 1.5T with a new multislab 3D double inversion recovery sequence that selectively suppresses cerebrospinal fluid (CSF) and white matter (WM). Images show a clear delineation of GM from WM and CSF, also for small GM structures such as the entorhinal cortex, of importance in Alzheimer's disease. Feasibility is demonstrated for th...

Inversion of magnetic data is an important step towards interpretation of the practical data. Smooth inversion is a common technique for the inversion of data. Physical bound constraint can improve the solution to the magnetic inverse problem. However, how to introduce the bound constraint into the inversion procedure is important. Imposing bound constraint makes the magnetic data inversion a n...
