Hydrogen is nature’s simplest, lightest atom, consisting of a single proton and a single electron.2 Paradoxically, this “simplicity” in electronic structure leads to unique consequences for the chemical and physical properties of the element and its atomic, cationic, and anionic siblings. In its desire to possess either a totally empty or a totally filled 1s electron shell, hydrogen exhibits th...

Abstract Geological records of subduction earthquakes, essential for seismic and tsunami hazard assessment, are difficult to obtain at transitional plate boundaries, because upper-plate fault earthquake deformation can mask the zone signal. Here, we examine unusual shell layers within a paleolagoon Lake Grassmere, transition between Hikurangi Marlborough system. Based on biostratigraphic sedime...

ABSTRACT Using the MeerKAT radio telescope, a series of observations have been conducted to time known pulsars and search for new in globular cluster NGC 6440. As result, two discovered, 6440G 6440H, one which is isolated other non-eclipsing (at frequencies above 962 MHz) ‘Black Widow’, with very low mass companion (Mc > 0.006 M?). It joins binary discovered so far this that all masses &...

BACKGROUND Full Monte Carlo (MC)-based SPECT reconstructions have a strong potential for correcting for image degrading factors, but the reconstruction times are long. The objective of this study was to develop a highly parallel Monte Carlo code for fast, ordered subset expectation maximum (OSEM) reconstructions of SPECT/CT images. The MC code was written in the Compute Unified Device Architect...

In this paper, we present and discuss the estimation of the Wishart Affine Stochastic Correlation (WASC) model introduced in Da Fonseca et al. (2006) under the historical measure. We review the main estimation possibilities for this continuous time process and provide elements to show that the utilization of empirical characteristic function-based estimates is advisable as this function is expo...

Çalışmanın konusunu, Trabzon-Araklı ilçesinde yer alan ve H.1283/M.1867 tarihinde inşa edilen Bereketli Mahallesi Masele Camii oluşturur. Cami, Müslüman Türkler tarafından sanat dünyasına kazandırılan ahşap camiler grubunda alır. Selçuklular eliyle Anadolu’ya taşınan camilerin en güzel örneklerini, bölgeye özgü özellikleri bünyesinde barından Trabzon camilerinde görmek mümkündür. Trabzon’un kır...
