All compounds present in the lithium-silicon binary phase diagram were synthesized and analyzed by electron energy-loss spectroscopy. In order to limit beam damage, and to develop a fast and local method of characterizing silicon negative electrodes, the valence energy-loss spectrum region was investigated, in particular the very intense plasmon peak in these alloys. Experimental spectra are in...

Chronic subdural hematomas (CSDH), which are frequently encountered in neurosurgical practice, are, in the majority of cases, ideally treated with surgical drainage. Despite this common practice, there is still controversy surrounding the best surgical procedure. With lack of clear evidence of a superior technique, surgeons are free to base the decision on other factors that are not related to ...

A 5 – 30 kHz, high voltage atmospheric pressure discharge device is being investigated as an excitation source for atomic emission spectroscopy. Electron excitation energy and molecular rotational temperature of nitrogen have been measured in this plasma at voltages of approximately 2 kV and average power levels of 130 300 Watts with a 2 mm gap between electrodes. Iron and titanium lines have b...

geometrical computation 6: a reversible, conservative and rational-based model for Black hole computation JÉRÔME DURAND-LOSE?† LIFO, Université d’Orléans, B.P. 6759, F-45067 ORLÉANS Cedex 2. In the context of Abstract geometrical computation, the Black hole model of computation (and SAD computers) have been implemented. In the present paper, based on reversible and (energy) conservative stacks,...

A wire-to-plane discharge during the early phases of breakdown has been studied. The discharge has been modeled in a prolate spheroidal coordinate system with the wire shape taken as a hyperboloid of revolution. Four simultaneous coupled, time-dependent, nonlinear partial differential equations describe the electrical discharge. These are the conservation equations for ion and electron densitie...

Certain exotic phenomena in general relativity, such as backward time travel, appear to require the presence of matter with negative energy. While quantum fields are a possible source of negative energy densities, there are lower bounds—known as quantum inequalities—that constrain their duration and magnitude. In this paper, we derive new quantum inequalities for scalar fields in static space-t...

When the characteristic length of an elastic solid is down to the nanometer level, its deformation behavior becomes size dependent. Surface energy /surface stress have recently been applied to explain such dependency. In this paper, the effect of strain-independent surface stress on the deformation of an isotropic elastic solid containing a nanosized elliptical hole is studied by the finite ele...

If a Kerr black hole is connected to a disk rotating around it by a magnetic field, the rotational energy of the Kerr black hole provides an energy source for the radiation of the disk in addition to disk accretion. The black hole exerts a torque on the disk, which transfers energy and angular momentum between the black hole and the disk. If the black hole rotates faster than the disk, energy a...

Radius of quantum dot Exciton binding energy and electron-hole recombination probability are presented as the two important metrics for investigating effect of dot size on electronhole interaction in CdSe quantum dots. Direct computation of electron-hole recombination probability is challenging because it requires an accurate mathematical description of electron-hole wavefunction in the neighbo...
