Organogenesis and regeneration require coordination of cellular proliferation, regulated in part by secreted growth factors and cognate receptors, with tissue nutrient supply provided by expansion and patterning of blood vessels. Here we reveal unexpected combinatorial integration of a growth factor co-receptor with a heterodimeric partner and ligand known to regulate angiogenesis and vascular ...
Non-circular or improper Gaussian signaling has proven beneficial in several interference-limited wireless networks. However, all implementable coding schemes are based on finite discrete constellations rather than Gaussian signals. In this paper, we propose a new family of improper constellations generated by widely linear processing of a square M-QAM (quadrature amplitude modulation) signal. ...
BACKGROUND Neural tube defects (NTDs) are some of the most common congenital anomalies. Proper folic acid supplementation is a dominant risk factor, which has been shown to decrease the incidence of NTDs. In Canada, the incidence of neuroblastoma has presented a considerable decrease of 60% as a result of enrichment cereal grain flours with synthetic folic acid. The aim of this study was to inv...
When physicians' conflicts of interest arise from ties with drug firms, we should shift our focus to the pharmaceutical industry and improper dependencies that cause institutional corruption. This article analyzes eight forms of improper dependencies on pharma and proposes reforms.
excessive vegetative growth may bring about improper pollination and consequently lead to reduced fruit set and misshapen fruits. paclobutrazol (pp333) reduces vegetative growth. on the other hand, balanced nutrient uptake at all developmental stages increases fruit quality and yield. an experiment was conducted with the aim of reducing vegetative growth and improving yield of strawberry, selva...
