Radar engineers and operators measure the radar return of a given target from a given angle in terms of its Radar Cross Section (RCS), from which they can detect and completely identify that target as its type, direction, and speed. The RCS of a target may have a huge value from one angle and at the same time has a very small value from another angle. So the challenge is to reduce the RCS of an...

PURPOSE The authors investigated intercellular communication among cultured rat retinal pigment epithelial (RPE) cells isolated from dystrophic Royal College of Surgeons (RCS) rats by studying the conduction of the [Ca2+]i wave elicited by mechanical stimulation. The effect of protein phosphorylation was measured by modulating the protein kinase C (PKC), protein kinase A (PKA), and tyrosine kin...

Obesity-driven type 2 diabetes (diabesity) involves complex genetic and environmental interactions to trigger disease. Here, we combine variable numbers of known quantitative trait loci (QTL) for obesity and diabetes contributed by New Zealand Obese (NZO/HlLt) and Nonobese Nondiabetic (NON/Lt) strains in the form of 10 interval-directed recombinant congenic strains (RCS), with NON/Lt as the bac...

The Rcs signal transduction system of Escherichia coli regulating capsular polysaccharide synthesis (cps) genes is activated by overexpression of the djlA gene encoding a cytoplasmic membrane-anchored DnaJ-like protein. However, by monitoring the expression of a cpsB'-lac fusion in pgsA- and mdoH-null mutants in which the Rcs system is activated, we found that the Rcs activity was further incre...

In this paper, a novel method of partial coating to reduce the Radar Cross Section (RCS) of a complex shaped perfectly electrically conducting (PEC) aircraft, of electrically large size, is proposed. The physical optics (PO) method is used to identify the hot spots of the PEC aircraft. An empirical procedure is then proposed to coat partial contiguous areas with Radar Absorbent Material (RAM). ...

Resonant cyclotron scattering (RCS) in pulsar magnetospheres is considered. The photon diffusion equation (Kompaneets equation) for RCS is derived. After some deductions, a generalized form of Kompaneets equation is obtained. The numerical calculations show that there exist not only up scattering but also down scattering of RCS, depending on the parameter space. Its possible applications to mag...

In the mammalian spinal cord, Renshaw cells (RCs) are excited by axon collaterals of motoneurons (MNs), and in turn, provide recurrent inhibition of MNs. They are considered an important element in controlling the motor output. However, how RCs are modulated by spinal circuits during motor behaviors remains unclear. In this study, the physiological nature of inhibitory synaptic inputs to RCs in...

A differential game guidance law for an endoatmospheric interceptor missile steered by aero fins and reaction jets is developed in this paper with bounded controls. For a low-altitude endoatmospheric interceptor, the propellant of the reaction-jet control system (RCS) is restricted by the missile configuration. Considering propellant limits, the effect of the RCS thrust on homing performance is...

In United States design practice, three system performance factors (R, Cd, and o) characterize the inelastic behavior of structures and are a crucial component of common elastic design methodologies. However, for steel-concrete composite frame systems these factors have been selected based on comparisons to more traditional and well-studied reinforced concrete and structural steel frame system...

Observer ratings were collected using instruments designed to measure the Diagnostic and Statistical Manual of Mental Disorders (4th ed.; American Psychiatric Association, 1994) personality disorders (Personality Diagnostic Questionnaire-4+ [PDQ-4+]; Hyler, 1994), the Big Five model (B5M; Goldberg's [1999] International Personality Item Pool), and Rorschach-derived constructs. For the latter, w...
