This paper develops and analyzes a new class of detect-and-forward cooperative diversity protocols adopting complete complementary code sets spreading. The proposed protocol employs a multi-band DS-CDMA transmission tailored to their distinct correlation properties. The complete complementary codes sets have an impulsive autocorrelation sum among each set and orthogonality between respective co...

grapes are among the world most planted horticultural crops. since the last century, attempts have been made to improve the quality of grapes in the world. meanwhile, the necessity of having knowledge about the history of progenies families led to the link between genealogy and breeding. considering some previous mislabeling, in order to find out the accuracy of the controlled crosses as well a...

Thirty-one proteins are known to form extracellular fibrillar amyloid in humans. Molecular information about many of these proteins in their monomeric, intermediate or fibrillar form and how they aggregate and interact to form the insoluble fibrils is sparse. This is because amyloid proteins are notoriously difficult to study in their soluble forms, due to their inherent propensity to aggregate...

We investigated by W-band (94 GHz) transient electron paramagnetic resonance (TREPR) and photoinduced absorption (PIA) spectroscopy two fullerene derivatives bearing a nitroxide radical unit. After pulsed laser photoexcitation of the molecules in liquid toluene solution, complex EPR spectra are recorded, with lines in absorption and emission. The intrinsic higher spectral and temporal resolutio...

Semi-classical simulations of the UV-photoabsorption cross sections of adenine, guanine, cytosine, thymine, and uracil in gas phase were performed at the resolution-of-identity coupled cluster to the second-order (RI-CC2) level. With the exception of cytosine, the spectra of the other four nucleobases show a two band pattern separated by a low intensity region. The spectrum of cytosine is shape...

Palladium atoms generated by thermal evaporation and laser ablation were reacted with and trapped in F2/Ar, F2/Ne, and neat F2 matrices. The products were characterized by electronic absorption and infrared spectroscopy, together with relativistic density functional theory calculations as well as coupled cluster calculations. Vibrational modes at 540 and 617 cm(-1) in argon matrices were assign...

The Personal Access Satellite System (PASS) strawman design, as described in the PASS Concept Study Report, (hereafter referred to as the Strawman Design) utilizes a hybrid Time Division Multiple Access (TDMA)/ Frequency Division Multiple Access (FDMA) implementation. TDMA is used for the forward direction (from Suppliers to Users), and FDMA for the return direction (from Users to Suppliers). I...

2, 3-Dichloro-5,8-dimethoxy-1,4-naphthoquinone (DDNQ) is a synthetic naphthaquinone which has shown reduced chemotoxicity and enhanced chemotherapeutic activity in in vitro studies. The ability of DDNQ to serve as a chemical dopant of graphene resulting improved performance of graphene by tuning its band gap is also being explored. In this report surface enhanced Raman scattering (SERS) spectro...

The Escherichia coli gsk gene encoding guanosine kinase was cloned from the Kohara gene library by complementation of the E. coli gsk-1 mutant allele. The cloned DNA fragment was sequenced and shown to encode a putative polypeptide of 433 amino acids with a molecular mass of 48,113 Da. Minicell analysis established the subunit M(r) as 43,500. Primer extension analysis indicated the presence of ...

In DS-CDMA cellular communications systems, the single frequency reuse can be utilized. Since large other-cell interference is produced, the well known soft handover or site diversity must be used. If the single frequency reuse is not utilized to avoid the other-cell interference, we will face the frequency allocation problem, similar to FDMA systems. In this paper, a DS-CDMA cellular system us...
