In wireless power receiver systems, the buck converter is widely used to step down higher rectified voltage derived from coil, a lower output for immediate battery charging process. this article, presence and effect of right-half-plane (RHP) zeros found in small-signal inductor-current-to-duty-ratio output-voltage-to-duty-ratio transfer functions system on control performance, are investigated....

Abstract We have calculated the amount of radioactive heat production (RHP) that could possibly prevent postulated underground ocean Enceladus from freezing. An internal source is necessary to justify observed output and allow tidal dissipation heating models work. Also based on terrestrial evidence, we assumed most common radiogenic element can produce such 238 U. Our results show a minimum in...

Background: Melanoma is a common and malignant cutaneous tumor, which is responsible for a large proportion of skin cancer deaths. Dendritic cell (DC)-based vaccines have achieved positive results in the treatment of melanoma because of their ability to induce cytotoxic response to facilitate tumor elimination. Objective: To improve the efficacy of dendritic ce...

INTRODUCTION Equity in access to and utilization of health services is a common goal of policy-makers in most countries. The current study aimed to evaluate the distribution of need and access to health care services among Iran's rural population between 2006 and 2009. METHODS Census data on population's characteristics in each province were obtained from the Statistical Centre of Iran and Na...

The isomonodromic tau function defined by Jimbo-Miwa-Ueno vanishes on the Malgrange’s divisor of generalized monodromy data for which a vector bundle is nontrivial, or, which is the same, a certain Riemann–Hilbert problem has no solution. In their original work, Jimbo, Miwa, Ueno provided an algebraic construction of its derivatives with respect to isomonodromic times. However the dependence on...

In this work, the double and triple poles soliton solutions for Gerdjikov-Ivanov(GI) type of derivative nonlinear Schr\"{o}dinger equation with zero boundary conditions(ZBCs) nonzero conditions(NZBCs) are studied via Riemann-Hilbert (RH) method. Though spectral problem analysis, we first give out Jost function scattering matrix under ZBCs NZBCs. Then according to analyticity, symmetry asymptoti...

We derive a determinant formula for the WKB exponential of singularly perturbed Zakharov-Shabat system that corresponds to the semiclassical (zero dispersion) limit of the focusing Nonlinear Schrödinger equation. The derivation is based on the RiemannHilbert Problem (RHP) representation of the WKB exponential. We also prove its independence of the branchpoints of the corresponding hyperelliptic...

A 40-year-old man first presented to medical attention 13 years before our evaluation with painful right-sided vision loss accompanied by neck pain and headache. There was mild proptosis of his right eye and disc edema on funduscopy. MRI of the brain with gadolinium demonstrated hypertrophic dural enhancement, orbital pseudotumor, and right optic nerve compression. CSF examination revealed an o...

The series-series compensation topology is widely adopted in many wireless power transfer applications. For such systems, their receiver part typically involves a dc–dc converter with front-stage full-bridge diode rectifier, to process the high-frequency transmitted ac into dc output voltage for load. It recently reported that current source nature of will introduce right-half-plane (RHP) zeros...
