This study estimates the surface soil moisture content in a case situated Vietnamese Red River Delta, using Landsat 8 satellite images. The trapezoidal relationship between land temperature and vegetation index was used to obtain wetness indexes. A split-window algorithm developed overcome missing of atmospheric data. method validated with ground truth across different covers. RMSE calculated m...

We propose an approach for real-time sentiment-based anomaly detection (RSAD) in Twitter data streams. Sentiment classification is used to split the data into independent streams (positive, neutral, and negative), which are then analyzed for anomalous spikes in the number of tweets. Four approaches for evaluating the data streams are studied, along with the parameters that adjust their sensitiv...

We employ a planar metamaterial structure composed of a split-ring-resonator (SRR) and paired nano-rods to experimentally realize a spectral response at near-infrared frequencies resembling that of electromagnetically induced transparency. A narrow transparency window associated with low loss is produced, and the magnetic field enhancement at the center of the SRR is dramatically changed, due t...

the aim of this study was to compare the lateral window and osteotome techniques for sinus lifting using histological and histomorphometric methods.in this clinical trial 10 patients (a total number of 14 sinus areas) who needed implant treatment in the atrophic posterior maxilla were enrolled. in all the cases the residual bone height between the sinus floor and the alveolar crest was less tha...

background: the aim of this study was to determine the correlation between ultrastructural studies for pinopodes expression after ovarian hyperstimulation and progesterone injection in mice. materials and methods: adult nmri mice were superovulated using human menopasual gonadotropic (hmg) and human chorionic gonadotropic (hcg) hormones; after that, daily injection of progesterone (1 mg/mouse) ...

A unified treatment for the fast and spectrally accurate evaluation of electrostatic potentials with periodic boundary conditions in any or none three spatial dimensions is presented. Ewald decomposition used to split problem into real-space Fourier-space parts, Fast Fourier Transform (FFT)-based Spectral (SE) method accelerate computation latter, yielding total runtime O(N?log(N)) N sources. k...

Gaussian split Ewald (GSE) is a versatile Ewald mesh method that is fast and accurate when used with both real-space and k-space Poisson solvers. While real-space methods are known to be asymptotically superior to k-space methods in terms of both computational cost and parallelization efficiency, k-space methods such as smooth particle-mesh Ewald (SPME) have thus far remained dominant because t...

We examine the PT-symmetry-breaking transition for a magnetic metamaterial of a finite extent, modeled as an array of coupled split-ring resonators in the equivalent circuit model approximation. Small-size arrays are solved completely in closed form, while for arrays larger than N=5 results were computed numerically for several gain and loss spatial distributions. In all cases, it is found that...
