Özetçe —Bu bildiride, yüksek çözünürlüklü görüntülerde bileşik yapıların otomatik sezimi için bir yöntem sunmaktayız. Verilen bir sorgu bölgesi için amacımız, birden çok sıradüzensel bölütlemeden benzer uzamsal yerleşim ve karakteristiklerde birbiriyle uyumlu bölgeler bulmaktır. Bölgeleri olasılıksal değişkenler olarak temsil ederek ve uzamsal olarak birbirine yakın düğümleri birbirine bağlayar...

When a double-strand break has a gap between the broken ends, the missing information can be restored through synthesis from a homologous template. Here we address the question of how long such a gap can be before this process fails. We measured the frequency of homologous repair in the Drosophila germ line following the creation of gaps of specific sizes ranging from 3.8 to 210 kb. We found th...

DNA double-strand breaks (DSBs) are the most dangerous form of DNA damage and can lead to death, mutation, or malignant transformation. Mammalian cells use three major pathways to repair DSBs: homologous recombination (HR), classical nonhomologous end joining (C-NHEJ), and alternative end joining (A-NHEJ). Cells choose among the pathways by interactions of the pathways with CtIP and 53BP1. HR i...

In the physical vacuum of QCD, the energy density of lightquark fields strongly coupled to slowly varying gluon fields can be negative. The states that drive this energy density lowest are condensates of pairs of quarks and antiquarks of nearly opposite momenta. These quark-antiquark condensates break chiral symmetry. They may also affect other features of hadronic physics, such as the range of...

We consider the issue of testing a time series for a unit root in the possible presence of a break in a linear deterministic trend at an unknown point in the series. We propose a new break fraction estimator which, where a break in trend occurs, is consistent for the true break fraction at rate Op(T). Unlike other available estimators, however, when there is no trend break our estimator converg...

The Greenland ice sheet (GrIS) advanced onto the continental shelf during the last glacial period. While deglacial records for when the GrIS withdrew onto the modern coastline are relatively abundant, the timing of early GrIS retreat on the shelf is poorly constrained. Here we use planktic foraminiferal d18O, sediment grain size, sedimentation rates, and 14C ages in southeastern Davis Strait co...

We selected a sample of 33 Gamma–Ray Bursts (GRBs) detected by Swift, with known redshift and optical extinction at the host frame. For these, we constructed the de–absorbed and K–corrected X–ray and optical rest frame light curves. These are modelled as the sum of two components: emission from the forward shock due to the interaction of a fireball with the circum–burst medium and an additional...

By evaluation of the blasting results, a proper blast pattern can be presented. It is, therefore, essential to employ a reliable method to evaluate blastings for the effective control and optimization of the main cycle operations. This paper aims to propose a criterion for evaluating the blasting results such as the fragmentation, muckpile condition, back-break, and fly rock, and to make a poss...

The currents flowing across the rim of atoll Raroia were investigated with a 1 year-long dataset wave, water level and currents. Offshore waves break on edge reef outside atoll's drive current into lagoon, through shallow hoa that cut rim. additional volume generated by this wave driven flow induces an elevation throughout lagoon is evacuated back open ocean deep pass. inside also astronomical ...
