this paper presents a design of an uwb downconversion integrated cmos resistive ring mixer with linear voltage regulator (lvr), to supply required biasing voltages for the mixer section. the designed mixer circuit has been optimized for using in heart rate extraction system with microwave doppler radar at 2.4ghz frequency. this mixer needs 2 dc bias voltages equal to 0.5 and 1 volts for its bes...

Lymphomas are solid tumors of immune system and Non-Hodgkin Lymphomas (NHL) is the most prevalent lymphomas; with wide ranges of histological and clinical features, it is so difficult to identify them. Herein, various bioinformatics tools (such as gene differential expressions, epigenetics and protein analysis) employed to find new treatment approach for NHL based on gene expression variation b...

background:   objective: to understand the changes of mirnas in endometriosis.   materials and methods: with real-time rt-pcr, we investigated the mir-143 and mir-145 expression in eutopic (eu, n=2) and ectopic endometrium (ec, n=11) (from women with endometriosis) (as well as eu+ec, n=11), along with the normal endometrium (en, n=22) (from women without endometriosis, but with leiomyoma). resu...

The present study aimed to explore whether focused written corrective feedback has any significant effect on improving undergraduate university students’ paragraph writing ability; if so, the study fur- ther sought to demonstrate whether this effect differs within high/low self-regulated learners or not. For the purpose of the study, 60 BA university students wer...

the aim of the present study was to investigate the effects of various scheduled practices (self-regulated and non-self-regulated) on the acquisition, retention and transfer of simple and complex tracking tasks. 96 right-handed undergraduate students (age rang: 18-24 years old) volunteered to participate in this study (48 females, 48 males). these students participated in physical education cla...
