Fluvial strath terraces provide a record of river incision and the timing of climatic perturbations to the fluvial system. Dating depositional surfaces like terraces that are older than the range of C, however, is difficult. We employ a Ž . cosmogenic radionuclide CRN profile technique that addresses a major problem of CRN dating on such surfaces: nuclide inheritance. By measuring Be and Al pro...

The popularity of ubiquitous Internet services has spurred the fast growth of wireless communications by launching data hungry multimedia applications to mobile devices. Powered by spectrum agile cognitive radios, the newly emerged cognitive radio networks (CRN) are proposed to provision the efficient spectrum reuse to improve spectrum utilization. Unlicensed users in CRN, or secondary users (S...

Two experiments were conducted simultaneously to evaluate the effects of supplemental ground flaxseed on site and extent of digestion and growth performance in beef cattle grazing summer native range. Six Angus heifers (initial BW 367 +/- 8.0 kg) fitted with ruminal and duodenal cannulas were used in Exp. 1, and 18 Angus cross steers (initial BW 368 +/- 4.6 kg) were used in Exp. 2. Cattle from ...

CrAlN coatings have earned significant attention for use in cutting tool coating applications due to their excellent properties such as high hardness and superb oxidation resistance. It is well known that the interlayer between substrate can influence mechanical of coatings. In this work, three interlayers—CrN, CrZrN, CrN/CrZrSiN—were synthesized a tungsten carbide improve thermal stability coa...

OBJECTIVE To describe for surgeons contemplating performing cytoreductive nephrectomy (CRN) on patients after neoadjuvant sunitinib compared to a benchmark of open radical nephrectomy, describing technical difficulties, safety and feasibility. PATIENTS AND METHODS We compared measurable surgical parameters and perioperative complications in 22 patients with metastatic renal cell carcinoma (mR...

The last few years have seen a rise in the interest in early transition-metal and rare-earth nitrides, primarily based on ScN and CrN, for energy harvesting by thermoelectricity and piezoelectricity. This is because of a number of important advances, among those the discoveries of exceptionally high piezoelectric coupling coefficient in (Sc,Al)N alloys and of high thermoelectric power factors o...

Cognitive radio networks (CRN) sense spectrum occupancy and manage themselves to operate in unused bands without disturbing licensed users. The detection capability of a radio system can be enhanced if the sensing process is performed jointly by a group of nodes so that the effects of wireless fading and shadowing can be minimized. However, taking a collaborative approach poses new security thr...

The genome-wide transcriptome profiling of cancerous and normal tissue samples can provide insights into the molecular mechanisms of cancer initiation and progression. RNA Sequencing (RNA-Seq) is a revolutionary tool that has been used extensively in cancer research. However, no existing RNA-Seq database provides all of the following features: (i) large-scale and comprehensive data archives and...
