Selection of maize (Zea mays) hybrids with wide adaptability across diverse farming environments is important, prior to recommending them to achieve a high rate of hybrid adoption. Grain yield of 14 maize hybrids, tested in a randomized completeblock design with four replicates across 22 environments in Iran, was analyzed using site regression (SREG) stability model. The biplot technique facili...

BACKGROUND/AIMS Phorbol myristate acetate (PMA) exerts a pleiotropic effect on the growth and differentiation of various cells. Protein kinase Cs (PKCs) plays a central role in mediating the effects of PMA on cells. The present study investigated whether the down-regulation of protein kinase C-ε (PKC-ε) is involved in the inhibition of vascular smooth muscle cell (VSMC) proliferation caused by ...

Two-dimensional gel electrophoresis of in vitro phosphorylated proteins coprecipitated by CD2 monoclonal antibody (mAb) from Brij58 lysates of resting human T lymphocytes and natural killer (NK) cells resulted in the identification of a novel 29/30-kD disulfide-linked dimer (pp29/30). Comparative two-dimensional analysis of CD2, CD3, CD4, CD5, and CD8 immunoprecipitates revealed that pp29/30 as...

A new active feedback network is proposed for reducing intermodulation distortion (IMD). It is based on using the existing second harmonic zone (SHZ) distortion energy generated by the amplifier to predistort the input signals optimally to obtain a linear output. The technique is analyzed theoretically and practical results demonstrate the linearization performance. The measured two-tone test s...

Severe malarial anemia (SMA) is a leading cause of mortality among children in sub-Saharan Africa. Although the novel cytokine, interleukin (IL)-23, promotes anemia in chronic inflammatory diseases, the role of IL-23 in SMA remains undefined. Since IL-23 and IL-12 share the IL-12p40 subunit and IL-12Rbeta1 receptor, and are down-regulated by IL-10, relationships among these cytokines were explo...

We study the phase diagram of an interacting lattice gas of two species of particles and holes, driven out of equilibrium by a local hopping bias (denoted by ‘E’). Particles interact by excluded volume and nearest-neighbor attractions. We present a detailed Monte Carlo investigation of the phase diagram. Three phases are found, with a homogenous phase at high temperatures and two distinct order...

The identification of type Ib/c supernovae as GRB progenitors is motivated by the association of GRB980425 with SN1998bw and of GRB030329 with SN2003dh. While the γ-ray luminosity of GRB030329 was typical to cosmological GRBs, the luminosity of the nearby (40 Mpc) GRB980425 was ∼ 5 orders of magnitude lower. The large luminosity difference is commonly explained by hypothesizing that either SNe ...

Succession has been of enduring interest since the inception ecological theory and remains central to contemporary questions (Chang & Turner, 2019; Meiners et al., 2015). Primary succession involves changes in abiotic environment that modulate outcome biotic interactions but mechanisms, notably facilitation, inhibition tolerance, have contentious (Connell Slatyer, 1977; Farrell, 1991; Pickett 1...
