Lower plant transpiration rate (TR) under high vapor pressure deficit (VPD) conditions and early plant vigor are proposed as major traits influencing the rate of crop water use and possibly the fitness of chickpea lines to specific terminal drought conditions-this being the major constraint limiting chickpea productivity. The physiological mechanisms underlying difference in TR under high VPD a...

Thyroid hormone regulates adult hippocampal neurogenesis, a process involved in key functions, such as learning, memory, and mood regulation. We addressed the role of thyroid hormone receptor TR 1 in adult hippocampal neurogenesis, using mice harboring a TR 1 null allele (TR 1 / ), overexpressing TR 1 6-fold (TR 2 / ), and a mutant TR 1 (TR 1 ) with a 10-fold lower affinity to the ligand. While...

This paper provides an overview of some time-reversal (TR) techniques for remote sensing and imaging using ultrawideband (UWB) electromagnetic signals in the microwave and millimeter wave range. The TR techniques explore the TR invariance of the wave equation in lossless and stationary media. They provide superresolution and statistical stability, and are therefore quite useful for a number of ...

We report on time-resolved broadband transient reflectivity (tr-bb-TR) measurements performed a bulk single crystal of T$_d$-MoTe$_2$ as function the incident pump fluence (F). Tr-bb-TR data unveil photoinduced electronic changes progressing sub-picosecond timescale well dynamics coherent low-frequency $^1A_1$ interlayer shear phonon. Our results indicate gradual evolution both TR and Fourier i...

Studies on the thymic ontogeny of naturally arising CD4(+)CD25(+) regulatory T cells (TR cells) are complicated by the contamination of recirculating cells from the periphery (both activated CD4(+) T and TR cells). We investigated TR cells in anti-CD4 antibody transgenic (Tg) (GK) mice that continuously deplete peripheral CD4 T cells but not thymocytes so that the generation of thymic TR cells ...

Generalized resistance to thyroid hormone (GRTH) is a syndrome of hyposensitivity to triiodothyronine (T3) that displays autosomal dominant inheritance. The genetic defect commonly lies in the ligand-binding domain of one of the TR beta alleles. Since there are two major thyroid hormone receptor (TR) isoforms, TR alpha and TR beta, it is not known how the mutant receptor mediates a dominant neg...

Lemma 14. Let f : D → E be a projection morphism. Then Tr(f) satis(es the following properties: (1) If {u1; : : : ; un} is compatible and (u1; v1) : : : ; (un; vn)∈Tr(f ); then {v1; : : : ; vn} is also compatible and (u1 · · · un; v1 · · · vn)∈Tr(f ). (2) If (u; v)∈Tr(f) and v′ v, then there is some u′ u such that (u′; v′)∈Tr(f). (3) If (u; v); (u′; v)∈Tr(f) with u ↑ u′ then u = u′. (4) If (u; ...
