This paper describes the synthesis of digitally excited pencil/flat top dual beams simultaneously in a linear antenna array constructed of isotropic elements. The objective is to generate a pencil/flat top beam pair using the excitations generated by the evolutionary algorithms. Both the beams share common variable discrete amplitude excitations and differ in variable discrete phase excitations...

Background: Flexible Flat Foot (FFF), a common foot deformity decreasing medial longitudinal arch height is often comorbid with subtalar joint pronation causing physical activity difficulties in this population. Among the orthotic insoles prescribed for improving foot function, foot orthoses with medial heel skive technique have a limited research background. The present study aimed to investig...

The analysis of the cycle 17 STIS CCD spectroscopic flats (Niemi 2010) pointed to the need to create a new dust mote image for the low resolution grating (L-mode) P-flats. This ISR describes the creation of the new L-mode P-flat from low resolution exposures taken during cycles 18 and 19. The document also analyzes the time dependence of the dust mote images as well as that of the intrinsic fla...

An on-orbit flat-field monitoring program was initiated for the MAMA detectors with the goals of comparing the pre-launch flat-field characteristics with those observed on-orbit, measuring the stability of the FUVand NUV-flats, and creating updates to the reference flats. We found that the NUV-MAMA flat-field images at nominal (1024x1024) resolution are well corrected with pre-launch flats. Tha...

Purpose: The present study investigated the most appropriate footprint index and its related parameters for the diagnosis of flatfoot, especially in cases with mild deformity. Methods: In total, 148 footprints were recorded from 77 young women with flatfoot. Footprints were classified into three groups of mild, moderate, and sever. Footprint indexes included Sztriter-Godunov (KY), Clarke’s Ang...

MOTIVATION Clustering is one of the most widely used methods in unsupervised gene expression data analysis. The use of different clustering algorithms or different parameters often produces rather different results on the same data. Biological interpretation of multiple clustering results requires understanding how different clusters relate to each other. It is particularly non-trivial to compa...

‎we call a ring $r$ right generalized semiperfect if every simple right $r$-module is an epimorphic image of a flat right $r$-module with small kernel‎, ‎that is‎, ‎every simple right $r$-module has a flat $b$-cover‎. ‎we give some properties of such rings along with examples‎. ‎we introduce flat strong covers as flat covers which are also flat $b$-covers and give characterizations of $a$-perfe...
