Displaced phase center antenna (DPCA) and along-track interferometry (ATI) are two classical techniques used to determine synthetic aperture radar-ground moving target indication (SAR-GMTI) field. According to the research from now, conventional DPCA is superior to ATI[1],[2]. But, even the conventional DPCA is not all that could be desired. This paper proposes the algorithm called region-corre...

This thesis presents a knowledge-based solution for retrieving English descriptions for objects in a collection. Based on detailed analysis of the errors made by a baseline system relying on surface-level features (i.e. term frequency), we infer that an ideal solution to this problem should use deeper representations of the meaning encoded in textual descriptions. Applied Textual Inference (ATI...

Fully quantum treatment explicitly presents the high harmonic generation as a three-stage process: above threshold ionization (ATI) is followed by the continuum electron propagation in a laser field and subsequent stimulated recombination back into the initial state. The contributions of all ATI channels add up coherently. All three stages of the process are described by simple, mostly analytic...

Orbital thermal infrared (TIR) remote sensing is an important tool for characterizing geologic surfaces on Earth and Mars. However, deposition of material from volcanic or eolian activity results in bedrock surfaces becoming significantly mantled over time, hindering the accuracy of TIR compositional analysis. Moreover, interplay between particle size, albedo, composition and surface roughness ...

possibility of the natural reservoir of variola virus among wild animals grew more important. Monkeypox virus was isolated from 20 clinical smallpox cases in West Africa among populations with close contacts with wild monkeys, but its epidemiological and virological differentiation from variola viruses was not difficult. During the virological studies of human monkeypox virus infections, a grou...

BACKGROUND Mobile smartphones are equipped with inclinometers enabling them to acquire angular clinical measures. The Scolioscreen has been developed in conjunction with a smartphone APP to enable the measure of the angle of trunk inclination (ATI) thus offering a convenient and reliable means to measure and screen for spinal deformities. The objective was to compare the reliability and accurac...

BACKGROUND In the placebo-controlled trial ACTG A5197, a trend favoring viral suppression was seen in the HIV-1-infected subjects who received a recombinant Ad5 HIV-1 gag vaccine. OBJECTIVE To identify individuals with initial viral suppression (plasma HIV-1 RNA set point <3.0 log(10) copies/ml) during the analytic treatment interruption (ATI) and evaluate the durability and correlates of vir...
