background: several studies have assessed the correlation of fetal choroid plexus cyst (cpc) and the risk of congenital anomalies, but few ones have discussed isolated cpc (with no other abnormal sonographic finding). objective: the aim of this study was to determine the outcome of isolated fetal choroid plexus cyst and to specify its clinical significance. materials and methods: this cross sec...

In fifth generation (5G) new radio (NR), the demodulation reference signal (DMRS) is employed for channel estimation as part of coherent physical uplink shared channel. However, DMRS spoofing poses a serious threat to 5G NR since inaccurate will severely degrade decoding performance. this correspondence, we propose exploit spatial sparsity structure detect spoofing, which motivated by fact that...

in this paper, lagrangian and equations describing one-dimensional anisotropic non-heisenberg model are studied. in this study we used the generalized coherent states in real parametrizations and the feynman path integral for these states in su(3) group. these equations describe nonlinear dynamics of non-heisenberg ferromagnetic chain completely. solutions of these equations are magnetic solito...

Hyperspectral anomaly detection is one of the main challenging topics in both military and civilian fields. The spectral information contained in a hyperspectral cube provides a high ability for anomaly detection. In addition, the costly spatial information of adjacent pixels such as texture can also improve the discrimination between anomalous targets and background. Most studies miss the wort...

Abstract We study bundle gerbes on manifolds M that carry an action of a connected Lie group G . show these data give rise to smooth 2-group extension by the hermitean line bundles This classifies equivariant structures gerbe, and its non-triviality poses obstruction existence structures. present new global approach parallel transport gerbe with connection, use it alternative construction this ...

Energy flux is a fundamental quantity for understanding internal wave generation, propagation, and dissipation. In this paper, the estimation of internal wave energy fluxes u p from ocean observations that may be sparse in either time or depth are considered. Sampling must be sufficient in depth to allow for the estimation of the internal wave–induced pressure anomaly p using the hydrostatic ba...

We present a coherent picture of the spin-statistics theorem in path integral formulation. The local path integral measure and Lorentz invariant local Lagrangian, when combined with Green’s functions defined in terms of time ordered products, ensure causality regardless of statistics. The Feynman’s m−iǫ prescription ensures the positive energy condition regardless of statistics, and the abnorma...

In this brief review, I discuss the new physics unveiled by neutrino oscillation experiments over the past several years, and discuss several attempts at understanding the mechanism behind neutrino masses and lepton mixing. It is fair to say that, while significant theoretical progress has been made, we are yet to construct a coherent picture that naturally explains non-zero, yet tiny, neutrino...

We study the dynamics near a 1 + 1 dimensional intersection of two orthogonal stacks of fivebranes in type IIB string theory, using an open string description valid at weak coupling, and a closed string description valid at strong coupling. The weak coupling description suggests that this system is invariant under eight supercharges with a particular chirality in 1 + 1 dimensions, and its spect...

Intraseasonal variability [ISV] in the Makassar Strait thermocline is examined through the analysis of along-channel flow, regional sea level anomaly and wind fields from January 2004 through November 2006. The dominant variability of 45–90 day in the Makassar Strait along-channel flow is horizontally and vertically coherent and exhibits vertical energy propagation. The majority of the Makassar...
