During a recent conversation, R . P. Agnew suggested a determination of the validity of the proposition that row-infinite Toeplitz transformations are more powerful than row-finite transformations . Before this proposition is examined, it is necessary to assign a precise meaning to it. Corresponding to every sequence s a regular rowfinite Toeplitz transformation A can be constructed such that t...

intercropping may be helpful manner to increase interception and utilization. the aim of this study was to compare radiation use efficiency and radiation interception in intercropping with sole cropping. an experiment was conducted at the agricultural research station, ferdowsi university of mashhad in the growing season of the year 2008. the experimental treatments were: 1- sole crop of bean 2...

let a and b be n × m matrices. the matrix b is said to be g-row majorized (respectively g-column majorized) by a, if every row (respectively column) of b, is g-majorized by the corresponding row (respectively column) of a. in this paper all kinds of g-majorization are studied on mn,m, and the possible structure of their linear preservers will be found. also all linear operators t : mn,m ---> mn...

BACKGROUND The purpose of this study was to perform a systematic review and meta-analysis of all available level I randomized controlled trials comparing single-row with double-row repair to statistically compare clinical outcomes and imaging-diagnosed re-tear rates. METHODS A literature search was undertaken to identify all level I randomized controlled trials comparing structural or clinica...

CONTEXT Double-row rotator cuff repair methods have improved biomechanical performance when compared with single-row repairs. OBJECTIVE To review clinical outcomes of single-row versus double-row rotator cuff repair with the hypothesis that double-row rotator cuff repair will result in better clinical and radiographic outcomes. DATA SOURCES Published literature from January 1980 to April 20...

This article reviews and summarizes research on death row inmates. The contributions and weaknesses of death row demographic data, clinical studies, and research based on institutional records are critiqued. Our analysis shows that death row inmates are overwhelmingly male and disproportionately Southern. Racial representation remains controversial. Frequently death row inmates are intellectual...
