Long terminal repeat retrotransposons (LTR-RTs) are the major DNA components in flowering plants. Most LTR-RTs contain dinucleotides 'TG' and 'CA' at the ends of the two LTRs. Here we report the structure, evolution, and propensity of a tomato atypical retrotransposon element (TARE1) with both LTRs starting as 'TA'. This family is also characterized by high copy numbers (354 copies), short LTR ...

Abstract Limited-transpiration rate at high evaporative demand (‘LTR’ trait) has potential to improve drought adaptation, crop water productivity and food security. The quantification of the implications LTR for consumption, biomass accumulation yield formation requires use dynamic modelling simulate physiological environmental processes interactions in target environments. Here, a new transpir...

purpose : to evaluate the correlation between inner segment/outer segment (is/os) line and external limiting membrane (elm) layer integrity at foveal center and visual outcome and to investigate the prognostic factors in optical coherence tomography (oct) that related to final visual acuity (va) and recovery time in acute central serous chorioretinopathy (csc) methods : we prospectively studied...

Deep drawing of cylindrical shapes with high limiting drawing ratio (LDR) values is relatively difficult. Annealing is a further operation, which in turn adds costs and consumes significantly time to the forming process. In the present work, cylindrical cups from brass sheet were made with only limited anneal during few steps, but having LDR of 9 that is about 2 times higher than previous works...

This investigation was directed at separating long-term reconstituting (LTR) stem cells in normal murine marrow from hematopoietic precursors detectable in short-term assays in vitro and in vivo, and then at determining whether purified LTR cells could themselves form colonies in culture. To do so, it was first necessary to identify culture conditions that would induce their growth while preser...

The avian retrovirus pp32 DNA endonuclease prefers to nick supercoiled DNA containing long terminal repeat (LTR) circle junction sequences at one or the other of two sites, each which mapped two nucleotides back from the circle junction. The sequence at the sites of nicking was (sequence: see text) where increases indicates the positions of the two alternative nicked sites. This site-specific n...

In this paper we present a robust controller design methodology for vehicle rollover prevention utilizing active steering. Control design is based on keeping the magnitude of the vehicle load transfer ratio (LTR) below a certain level in the presence of driver steering inputs; we also develop an exact expression for LTR. The proposed controllers have a proportional-integral structure whose gain...

The energy absorption of concrete filled, hollow-steel bracing was analyzed respect to geometric and mechanical parameters including the width-to-thickness section ratio, slenderness level, and strength of the steel and concrete. Local buckling and ductility were also investigated with respect to variation in the cross-section. The infill increased the compression resistance, even after multipl...

In this paper back-propagation artificial neural network (BPANN) is employed to predict the limiting drawing ratio (LDR) of the deep drawing process. To prepare a training set for BPANN, some finite element simulations were carried out. die and punch radius, die arc radius, friction coefficient, thickness, yield strength of sheet and strain hardening exponent were used as the input data and the...
