Let Kn denote the complete 2-fold multigraph of order n and let G be a bipartite subgraph of K4. We find necessary and sufficient conditions for the existence of a G-decomposition of Kn.

A fully integrated differential class-AB power amplifier has been designed in a 0.25um CMOS technology. It is intended for medium output power ranges such as Bluetooth class I, and has an operating frequency of 2.45GHz. By using two parallel output stages that can he switched on or off, a high efficiency can be achieved for both high and low output power levels. The simulated maximum output pow...

Clouds are affected by aspects of climate change and are a major influencing factor on the pre-vitamin D3 effective solar UV (UVD3) exposures that humans receive. The aim of this research was to investigate the influence of clouds on the short wavelength cut-off of the spectral UVD3 irradiances, on the maximum of the UVD3 spectral irradiances and on the magnitude of the UVD3 irradiances. The sp...

Defocusing effects in modulation transfer function (MTF) measurement of charge coupled device (CCD) cameras is the main focus of current paper. We introduce measuring Point-spread function (PSF) in order to calculate the MTF and further more we will study the shape of MTF and its cut-off frequency by adjusting the lens focusing in different locations. A collimated white light LED by broadband s...

Background: The nutritional status and systemic inflammation are thought to be associated with outcome in multiple types of cancer. The objective of this study was to determine the prognostic value of pretreatment albumin and fibrinogen combined prognostic grade (AFPG) in prostate cancer (PCa). Methods: 462 prostate cancer patients who had undergone androgen deprivation therapy (ADT) as first-l...

OBJECTIVE To identify key factors for predicting positive cone margin and appropriate cone length. METHODS We retrospectively reviewed the margin status of patients who received conization with high grade cervical intraepithelial neoplasia, along with other factors such as patient age, parity, preoperative cytology, size of disease, type of transformation zone, and cone length from patient re...
