Many people studied the Minimum Connected Dominating Set (MCDS) problem to introduce Virtual Backbone (VB) to wireless networks. However, many existing algorithms assume a static wireless network, and when its topology is changed, compute a new CDS all over again. Since wireless networks are highly dynamic due to many reasons, their approaches can be inefficient in practice. Motivated by this o...

The objective of this research was to study the effect of fat concentration from corn coproducts, fed during the growing phase on DMI, gain, carcass traits, digestibility, and rumen metabolism of steers. Exp. 1: 40 steers (age = 140d; BW = 185 ± 11 kg) were randomly allotted to 1 of 5 dietary treatments: (1) corn-based control (CNT), (2) 0% corn distillers solubles (CDS), (3) 10% CDS, (4) 19% C...

Figure S1. Photoluminescence spectra of CdSe/CdS nanocrystals (NCs) in (a) nanocrystal conjugate, linked with thioglycolic acid (TGA), upon correction for the contribution from Ga2O3 NC emission, (b) pure CdSe/CdS nanocrystal suspension, and (c) mixture of Ga2O3 and CdSe/CdS NCs without the TGA linker. The concentrations of CdSe/CdS NCs are identical in all panels, and are expressed in (a) as a...

A large area arrays (ca. 40 cm(2)) of CdS nanotube on silicon wafer are successfully fabricated by the method of layer-by-layer deposition cycle. The wall thicknesses of CdS nanotubes are tuned by controlling the times of layer-by-layer deposition cycle. The field emission (FE) properties of CdS nanotube arrays are investigated for the first time. The arrays of CdS nanotube with thin wall exhib...

The main goal of this work was to synthesize CdSe/CdS (core-shell) nanoparticles stabilized by polymer ligand using entirely aqueous colloidal chemistry at room temperature. First, the CdSe core was prepared using precursors and acid-functionalized poly(vinyl alcohol) as the capping ligand. Next, a CdS shell was grown onto the CdSe core via the layer-by-layer technique. The CdS shell was formed...

The desired control of particle size, doping element composition, and surface structure of carbon dots (CDs) are vital for understanding the fluorescence mechanism and exploring their potential applications. Herein, nitrogen-doped CDs (N-doped CDs) have been synthesized with tartaric acid and various alkylol amines (monoethanolamine, biethanolamine and triethanolamine) under microwave irradiati...

The introduction of credit default swaps (CDS) trading on an underlying firm may influence its future access to external financing and, hence, its precautionary demand for cash. In this paper, we empirically estimate this effect of CDS trading, using a comprehensive sample of North American corporate CDS introductions between 1997 and 2009. We show that corporate cash holdings, as a proportion ...

OBJECTIVES To investigate the association between satisfaction with conventional complete denture prostheses (CDs), impacts of CDs on daily living and personality profiles. MATERIALS AND METHODS Fifty-six patients (28 males and 28 females; mean age 53.79 ± 7.762 years) with fitted upper and lower removable CDs were recruited for this study. Clinical success of CDs was assessed according to sp...
