This paper addresses the anomaly correlation of the 500-hPa geopotential heights from a suite of global multimodels and from a model-weighted ensemble mean called the superensemble. This procedure follows a number of current studies on weather and seasonal climate forecasting that are being pursued. This study includes a slightly different procedure from that used in other current experimental ...

It is sometimes stated in the literature that the quantum anomaly is regarded as an example of the geometric phase. Though there is some superficial similarity between these two notions, we here show that the differences bewteen these two notions are more profound and fundamental. As an explicit example, we analyze in detail a quantum mechanical model proposed by M. Stone, which is supposed to ...

Using a reweighting technique combined with a low-mode truncation of the fermionic determinant, we estimate the quark-mass dependence of the QCD topological susceptibility with overlap fermions. In contrast to previous lattice simulations which all used non-chiral fermions, our results appear to be consistent with the simple continuum model of Dürr. This indicates that at current lattice spacin...

The application of anomaly detection has been given a special place among the different   processings of hyperspectral images. Nowadays, many of the methods only use background information to detect between anomaly pixels and background. Due to noise and the presence of anomaly pixels in the background, the assumption of the specific statistical distribution of the background, as well as the co...

this paper attempts to investigate the capability of the numerical finite element method for the removal of the regional effects from the observed gravity data from the dehnow anticline. from a geological point of view, the dehnow area is a part of the fars sedimentary basin south-east iran. the khamy formation and bangestan group are the oldest geological structures in the area that have outcr...

Toba Lake is one of the largest caldera lakes in world, formed by an enormous eruption about 74,000 years ago. The emergence hot spring manifestations around closely related to volcanic activity, which also controlled regional geological structures. There are two areas Toba: Simbolon and Pusuk Buhit, with several geothermal manifestations, such as fumaroles, springs, steaming ground. With large...

introduction: nager syndrome is a malformation resulting from problems in the development of the first and second branchial arches and limb buds. the cause of the abnormal development of the pharyngeal arches in nager syndrome is unknown. it is also unclear why affected individuals have bone abnormalities in their arms and legs. nager syndrome is thought to have an autosomal recessive inheritan...

turner syndrome is one of the best known chromosome anomalies in human being, by an approximate incidence of 1/2500 female at birth. the cause is a chromosomal aberration, mainly with the karyotype 45, x. ninety six patients aged 6 to 26 years with short stature were studied for chromosomal anomalies. out of these 82 were phenotypically female and 14 phenotypically male. twenty seven showed abn...

This study investigates the rainfall characteristics during intense over Yaan against a cold-anomaly background, aiming to refine understanding of different kinds events across complex terrain. Hourly rain gauge records, ERA5 reanalysis data and black body temperature cloud tops derived from FY-2E were used. The results show that regional (RREs) in exhibit west-to-east propagation, which is nor...

This study quantifies the association between COVID-19 economic downturn and 2020 tropospheric ozone anomalies above Europe western North America, their impact on long-term trends. Anomaly detection for an atmospheric time series is usually carried out by identifying potentially aberrant data points relative to climatological values. However, detecting from sparsely sampled ozonesonde profiles ...
