∗ Work supported by the U.S. DOE Contract No. DE-AC02-76SF00515. Abstract In this paper, we present design considerations to address the high gradient, wakefields, and RF efficiency issues for the JLC/NLC structures. We will present the rationale for the choices of phase advance, structure length, structure aperture, and other design aspects in the optimization of the structure. We will study t...
NLC-width is a variant of clique-width with many application in graph algorithmic. This paper is devoted to graphs of NLC-width two. After giving new structural properties of the class, we propose a $O(n^2 m)$-time algorithm, improving Johansson's algorithm \cite{Johansson00}. Moreover, our alogrithm is simple to understand. The above properties and algorithm allow us to propose a robust $O(n^2...
NLCk for k = 1, . . . is a family of algebras on vertex-labeled graphs introduced by Wanke. An NLC-decomposition of a graph is a derivation of this graph from single vertices using the operations in question. The width of such a decomposition is the number of labels used, and the NLC-width of a graph is the minimum width among its NLC-decompositions. Many difficult graph problems can be solved ...
The JLC/NLC is a normal conducting linear collider based on X-band RF technology. The collider is designed to cover the center-of-mass energy range from 90 GeV to 1.3 TeV with a luminosity of 2 to 3 ×1034 cm−2s−1 between 500 GeV and 1 TeV. The X-band RF system, which is based on the operating NLC Test Accelerator X-band RF system, was recently modified in a way that will ensure a less expensive...
In cognitive radio networks (CRNs), secondary users (SUs) can proactively obtain spectrum access opportunities by helping with primary users’ (PUs’) data transmissions. Currently, such kind of spectrum access is implemented via a cooperative communications based link-level frame-based cooperative (LLC) approach where individual SUs independently serve as relays for PUs in order to gain spectrum...
In the tumoral micro-environment (TME) of chronic lymphocytic leukemia (CLL), nurse-like cells (NLC) are tumor-associated macrophages which play a critical role in the survival and chemoresistance of tumoral cells. This pro-survival activity is known to involve soluble factors, but few data are available on the relative role of cells cross-talk. Here, we used a transcriptome-based approach to s...
Noctilucent, or "night-shining," clouds (NLCs) are a spectacular optical nighttime phenomenon that is very often neglected in the context of atmospheric optics. This paper gives a brief overview of current understanding of NLCs by providing a simple physical picture of their formation, relevant observational characteristics, and scientific challenges of NLC research. Modern ground-based photogr...
Dasatinib loaded nanostructured lipid carriers for effective treatment of corneal neovascularization
Dasa-NLC could significantly inhibit the corneal neovascularization.
The aims of this work were (i) to evaluate the potential of nanostructured lipid carriers (NLCs) as a tool to enhance the oral bioavailability of poorly soluble compounds using saquinavir (SQV), a BCS class IV drug and P-gp substrate as a model drug, and (ii) to study NLC transport mechanisms across the intestinal barrier. Three different NLC formulations were evaluated. SQV transport across Ca...
