In preparation to the experimental results which will be available in the future, we study geo-neutrino production for different models of mantle convection and composition. By using global mass balance for the Bulk Silicate Earth, the predicted flux contribution from distant sources in the crust and in the mantle is fixed within a total uncertainty of ±15%. We also discuss regional effects, pr...

| Proposed is a theoretically exact formula for inversion of data obtained by a spiral CT scan with a 2D detector array. The detector array is supposed to be of limited extent in the axial direction. The main property of the formula is that it can be implemented in a truly ltered backprojection fashion. First, one performs shift-invariant ltering of a derivative of the cone beam projections, an...

Proposed is a theoretically exact formula for inversion of data obtained by a spiral computed tomography (CT) scan with a two-dimensional detector array. The detector array is supposed to be of limited extent in the axial direction. The main property of the formula is that it can be implemented in a truly filtered backprojection fashion. First, one performs shift-invariant filtering of a deriva...

FiGD (Fingerprint Generator/Detector) is an open source Java application capable of detecting intellectual property violations in compiled Java programs without requiring access to the original source files. FiGD uses a modification of the n!gram method which is very accurate in discovering everything from blatantly copied source, to more advanced attempts of obfuscation (such as variable refac...

The notation is presented in Fig. 1, where the experimental setup is schematically shown. In ineq. (2) the notation is somewhat shortened, so that A = A(φA, λ) and B = B(φB , λ) pertains to the first detector while B′ = B′(φB , λ) and C ′ = C′(φC , λ) pertains to the second, and the expressions E(AB′), E(AC ′), and E(BC ′) are correlations of the results at detector 1 and detector 2 for differe...

We report electrical measurements of the current-induced spin polarization of the surface current in topological insulator devices where contributions from bulk and surface conduction can be disentangled by electrical gating. The devices use a ferromagnetic tunnel junction (permalloy/Al2O3) as a spin detector on a back-gated (Bi,Sb)2Te3 channel. We observe hysteretic voltage signals as the magn...

We utilized monochromatic high energy synchrotron x-rays (100 keV) to perform transmission diffraction measurements on bulk cadmium zinc telluride (Cd1-xZnxTe, x ~ 0.1) crystals used for room temperature radiation detectors. The highenergy measurements assess the crystalline properties throughout the thickness (2-3 mm) of the structures and we determined in combination with standard high-resolu...

We consider an infinite-volume brane world setup where a codimension one brane is coupled to bulk gravity plus a scalar field with vanishing potential. The latter is protected by bulk supersymmetry, which is intact even if brane supersymmetry is completely broken as the volume of the extra dimension is infinite. Within this setup we discuss a flat solution with a “self-tuning” property, that is...

Recently, Matiullah et al. described the use of NaOH/ethanol as an etchant for the CR-39 detector, and have determined the corresponding bulk and track etch properties from the track diameter method. In the present work, the bulk and track etch properties of CR39 in NaOH/ethanol were derived from direct measurements. The bulk etch rate has been found to increase with the molarity of NaOH/ ethan...

The portable high-resolution spectroscopy system includes an HPGe detector and an ORTEC digiDART (Figure 2). The HPGe detector includes a 3-, 5-, or 7-liter multi-attitude Dewar that allows the detector to be positioned in many directions without a significant loss of liquid nitrogen. The digiDART provides the battery-operated digital spectroscopy system which (1) applies high voltage to the de...
