Input buffered switches are known to suffer from head-of-line (HOL) blocking that limits the throughput to approximately 58.6%. It has been shown that 100% throughput can be achieved with virtual output queueing (VOQ) and an arbitration algorithm that controls the access to the switch fabric in each time slot. No weight-dependent algorithm was known that supports priorities, which are necessary...

Input buffered switches are known to suffer from head-of-line blocking that limits the throughput to 58.6%. It has been shown that with virtual output queueing (VOQ) 100% throughput can be achieved using arbitration algorithms. While dynamic algorithms decide based on some metrics in each time slot, a static arbitration called allocation reserves time slots for specific connections in advance. ...

Before CDDP was clinically used, combination chemotherapy regimens like BLM + MMC, VCR + MTX-LV + BLM, VCR + MTX-LV + BLM + MMC had been used for recurrent tumors of the head and neck. In a phase II study with CDDP, we experienced two patients with long-term survival (12, 15+) who were treated with CDDP as a second-line chemotherapy for recurrent tumors. Cisplatin was evaluated as a potentially...

A blocking semioval S in a projective plane of order q is a set of points such that every line meets S in at least one point (the blocking property), and every point of S lies on a unique tangent line (the semioval property). The set of points on the sides of a triangle, excluding the vertices, is a blocking semioval in any projective plane of order q > 2, and has size 3q − 3. The size of a blo...

In localization applications, the line-of-sight between anchors and targets may be blocked by obstacles in the environment. A target without line-of-sight to enough number of anchors cannot be unambiguously localized and is, therefore, said to be in a blind-spot. In this paper, we analyze the blind-spot probability of a typical target by using stochastic geometry to model the randomness in the ...

Head and neck squamous cell carcinoma is the sixth most common tumor worldwide, half of head patients are with oral (OSCC). 300,000 new cases OSCC were reported annually. Even multi-modality treatment, prognosis remains unsatisfactory. Thus, it urgent to discover novel therapeutic targets for OSCC. Some microarray studies have revealed that Keratin 4 (KRT4) downregulated in OSCC, whereas its ro...

This article proposes a method to identify blocking onset and decay by means of two stability indicators: enstrophy advection and its integral. The key to this technique is the use of local Lyapunov exponents for the barotropic vorticity equation, which can be approximated by the integral of enstrophy (IRE) over a fixed, finite region. The IRE can then be viewed as a measure of stability. Howev...

Magnetic nanoparticles of magnetite with a size ~8 nm synthesized different type coating were studied by ferromagnetic resonance in the temperature range from 7 to 300 K. The features experimental dependences parameters curve (the magnitude resonant field, line width and intensity) their approximation allowed us estimate values characteristic temperatures. Firstly, value Vervey dependence its o...

in order to analyze general and specific combining abilities and gene effects in sunflower for some agronomic traits, five cms lines and four restorer lines (tester) were crossed in a line × tester scheme. hybrids were evaluated in a randomized complete block design with three replications in the agriculture research station, university of tabriz, in 2009 and 2010 growing seasons. plant height,...
