This paper presents the first demonstration of high precision very high resolution tomographic SAR inversion with the assistance of TanDEM-X data. The data quality of TerraSAR-X and TanDEM-X is investigated. TomoSAR algorithms such as SVD-Wiener, Nonlinear Least Squares and SL1MMER are extended for mixed repeatand single-pass data stacks. A systematic approach is proposed for the fusion of Terr...

Copy Number Variations (CNVs) and Single Nucleotide Polymorphisms (SNPs) have been the major focus of most large-scale comparative genomics studies to date. Here, we discuss a third, largely ignored, type of genetic variation, namely changes in tandem repeat number. Historically, tandem repeats have been designated as non functional "junk" DNA, mostly as a result of their highly unstable nature...

Highly repetitive regions have historically posed a challenge when investigating sequence variation and content. High-throughput sequencing has enabled researchers to use whole-genome shotgun sequencing to estimate the abundance of repetitive sequence, and these methodologies have been recently applied to centromeres. Previous research has investigated variation in centromere repeats across euk...

Effects of six tillage practices on some soil microbiological properties and crop yields were evaluated for a clay soil (Typic Haploxererts) under semi-arid Mediterranean conditions in a three year study (2006-2009). The experiment was designed as a completely randomized-block with three replications. Treatments were: conventional tillage with residue incorporated (CT1), conventional tillage wi...

We have developed a graphical tool to model regularities in biological sequences. TandemGraph enables a user to study and analyze string regularities. An important application of this tool is when used to model tandem repeats found within chromosomes. We have used TandemGraph to graphically represent the tandem repeats in the human genome found by a tandem repeats program called TRed. The tool ...

the one-pot, multi-component synthesis of 4,4′-(arylmethylene)bis(1h-pyrazol-5-ols) by tandem knoevenagel-michael reaction of phenylhydrazine, ethyl acetoacetate and aldehydes in the presence of silica-bonded n-propylpiperazine sulfamic acid (sbppsa) as a recyclable solid acid catalyst was reported. sbppsa showed much the same efficiency when used in consecutive reaction runs.

Tandem solar cells have the potential to improve photon conversion efficiencies (PCEs) beyond the limits of single-junction devices. In this study, a triple-junction tandem design is demonstrated by employing three distinct organic donor materials having bandgap energies ranging from 1.4 to 1.9 eV. Through optical modeling, balanced photon absorption rates are achieved and, thereby, the photo-c...

This report proposes and compares a number of tandem-like feature extraction schemes. The proposed schemes use relative phone posteriors as confidence measures estimated from the MLP outputs directly or using Gamma function. The analysis of variances shows that the proposed tandem-like features discriminate better between phone classes than the conventional tandem features. But these capabiliti...

The purpose of this study was to investigate the concurrent effects of tandem length and bladder volume on dose to pelvic organs at risk (OARs) in HDR intracavitary brachytherapy treatment of cervical cancer. Twenty patients with locally advanced cervical cancer were selected for brachytherapy using Rotterdam applicators. The patients were CT scanned twice with empty and full bladder. Two treat...

We derive convexity results and related properties for the value functions of tandem queueing systems. The results for standard multi-server queues are new. For completeness we also prove and generalize existing results on tandems of controllable queues. The results can be used to compare queueing systems. This is done for systems with and without batch arrivals, and for systems with different ...
