BACKGROUND The principal aim of this study was to evaluate the feasibility of incorporating four-dimensional (4D)-computed tomography (CT)-based functional information into treatment planning and to evaluate the potential benefits of individualized beam setups to better protect lung functionality in patients with non-small cell lung cancer (NSCLC). METHODS Peak-exhale and peak-inhale CT scans...

I explicitly derive the optimal dynamic incentive contract in a general continuous-time agency problem where inducing static first-best action is not always optimal. My framework generates two dynamic contracts new to the literature: (1) a “quiet-life” arrangement and (2) a suspension-based endogenously renegotiating contract. Both contractual forms induce a mixture of first-best and non-first-...

Although optimal cladograms based on real data sets are readily demonstrated to be well loaded with phylogenetic data, statistical means of evaluating dependability of details of branch arrangements have been problematic. Exact values of four measures of branch arrangement reliability nonparametric bootstrap and jackknife proportions, the Decay Index, and Bayesian posterior probabilities were o...

This paper presents a systematic approach to quantifying the effectiveness of compliant grasps and fixtures of an object. The approach is physically motivated and applies to the grasping of twoand three-dimensional objects by any number of fingers. The approach is based on a characterization of the frame-invariant features of a grasp or fixture stiffness matrix. In particular, we define a set o...

In this paper an approach is proposed to derive an optimal layout of a Bengali Virtual Keyboard and hence forth seeking the desirable placement of all the keys in that layout within the constraints of space and the key size, thereby seeking to improve the text entry rate for an individual with normal human perception abilities. The approach is partly segmented in identifying the initial layout ...

To optimize dedusting efficiency in coal mines, a model of dust movement in heading roadway with farpressing-near-absorption ventilation system was built. The empirical drag force model was applied into the unsteady inter phase coupling modeling of air and dust flow. The Discrete Phase Modeling in Fluent was employed to solve the problem and unstructured grids were utilized to mesh the complex ...

The four-circuit parallel line on the same tower effectively solves problems faced by reconstruction and construction under condition of increasing shortage transmission corridors. Optimizing conductor phase sequence arrangement multiple lines is conducive to improving electromagnetic electrostatic coupling caused problems. This paper uses ATP-EMTP simulation software build a 500 kV multi-circu...

A system consisting of n components connected in a circular manner is called a circular consecutive-k-out-of-n: F system if it fails when k or more consecutive components fail. One of the most important problems for this kind of systems is to obtain the optimal component arrangement that maximizes the system reliability. As the number of components n increases, the amount of calculations would ...

The problem of obtaining optimal processing time in a distributed computing system consisting of ( N + 1) processors and :V communication links, arranged in a single-level tree architecture, is considered. It is shown that optimality can be achieved through a hierarchy of steps involving optimal load distribution, load sequencing, and processor-link arrangement. Closed-form expressions for opti...

This paper discusses algorithmic and implementation issues of optimally mapping a visualization pipeline onto a linear arrangement of wide-area network nodes to minimize the total delay. The first network node typically is a data source, the last node could be a display device ranging from a personal computer to a powerwall, and each intermediate node could be a workstation or computational clu...
