The bremsstrahlung power generated in the BTH and undulator and reaching the FEE has been simulated with the FLUKA [1] intra-nuclear cascade code. Calculations contain a detailed description of all 33 segments, quadrupoles, collimators, dump systems and surrounding walls and halls. Three bremsstrahlung sources are surveyed. The first one describes the photons arising from the interception of th...

Neutrino-pair bremsstrahlung by relativistic degenerate electrons in a neutron-star crust at densities 10 9 g cm ?3 < < 1:5 10 14 g cm ?3 is analyzed. The processes taken into account are neutrino emission due to Coulomb scattering of electrons by atomic nuclei in a Coulomb liquid, and electron-phonon scattering (the phonon contribution) and Bragg diiraction (the static-lattice contribution) in...

We compute the total radiated momentum carried by gravitational waves during scattering of two spinless black holes at lowest order in Newton's constant, $\mathcal{O}({G}^{3})$, and all orders velocity. By analytic continuation into bound state regime, we obtain $\mathcal{O}({G}^{3})$ energy loss elliptic orbits. This provides an essential step toward complete understanding third-post-Minkowski...

X-ray emission by sparks implies bremsstrahlung from a population of energetic electrons, but the details of this process remain a mystery. We present detailed statistical analysis of X-ray spectra detected by multiple detectors during sparks produced by 1 MV negative high-voltage pulses with 1 μs risetime. With over 900 shots, we statistically analyze the signals, assuming that the distributio...

In the region of large μ+μ− invariant mass, the decay spectrum of KL → μ +μ−γ deviates from the Dalitz pair spectrum, as a result of interference between conversion (KL → γ ∗γ → μ+μ−γ) and bremsstrahlung amplitudes. The latter is proportional to the KL → μ +μ− matrix element, whose 2γ-absorptive part appears to dominate the observed KL → μ +μ− decay rate. We examine the extent to which a scruti...

Introduction: The main purpose of this study was to compare transient ischemic dilation (TID) ratios in SPECT-low dose CT and SPECT Myocardial Perfusion Imaging (MPI) by application of different quantitative programs and quantify the possible shift in the upper normal limits of TID ratio in the SPECT-CT MPI. Methods: 149 Patients with low pre-test probability for coronary artery disease (CAD),...

Whether a patient with head and neck cancer has mandibular invasion or not is important in determining the method of resection surgery. But, no modality is adequately reliable when used alone in the evaluation of mandibular invasion. Therefore, to more accurately diagnose mandibular invasion in head and neck cancer, we used a new modality, namely, 99mTc methylene diphosphonate (MDP) or 99mTc hy...
