Tensile-strained InGaAs and GaAsSb layers have potential as strain-compensation for tunneling field-effect-transistors containing compressively strained channel layers. Here, we compare structural photoluminescence properties between 1% tensile-strained grown on InP substrates. Surface roughening the layer with increasing thickness proceeded much more slowly than layer. Differences in morpholog...
This paper is concerned with a trust region ap proximationmanagement framework AMF for solv ing the nonlinear programming problem in general and multidisciplinary optimization problems in par ticular The intent of the AMF methodology is to facilitate the solution of optimization problems with high delity models While such models are designed to approximate the physical phenomena they describe t...
The profound challenges facing clinicians, who must prescribe drugs in the face of dramatic variability in response, and the pharmaceutical industry, which must develop new drugs despite ever-rising costs, represent opportunities for cell biologists interested in rethinking the conceptual basis of pharmacology and drug discovery. Much better understanding is required of the quantitative behavio...
In many applications, such as decision support, negoti ation, planning, scheduling, etc., one needs to express re quirements that can only be partially satisfied. In order to express such requirements, we propose a technique called forward-tracking. Intuitively, forward-tracking is a kind o f dual o f chronological back-tracking: i f a program globally fails to find a solution, then a new exe...
This paper provides a study of integer linear programming formulations for the diameter con-strained spanning tree problem (DMSTP) in the natural space of edge design variables. Afterpresenting a straightforward model based on the well known jump inequalities a new stronger familyof circular-jump inequalities is introduced. These inequalities are further generalized in two ways:...
We have experimentally studied the photoresponse characteristics of strained In,Gar _ XAs (0.05<~<0.20) p-i-n photodiodes grown in small holes etched in GaAs substrates where the thickness of the i region exceeds the critical thickness. The diodes exhibit enhanced quantum efficiency and no degradation of the temporal response compared with devices grown on planar substrates, indicating that red...
A new derivative of the strained 3,3,6,6-tetramethylthiacycloheptyne (TMTH) bearing a functional handle is reported. Following an optimized synthesis, the handle was introduced by mild alkylation of the sulphur atom. The resulting functionalized strained 4,5-didehydro-3,3,6,6-tetramethyl-2,3,6,7-tetrahydrothiepinium (TMTI) proved to be stable and underwent extremely fast [3+2] cycloaddition rea...
Driven by the ever-increasing pace of drug discovery and the need to push the boundaries of unexplored chemical space, medicinal chemists are routinely turning to unusual strained bioisosteres such as bicyclo[1.1.1]pentane, azetidine, and cyclobutane to modify their lead compounds. Too often, however, the difficulty of installing these fragments surpasses the challenges posed even by the constr...
Self-ordering growth of nanoarrays on strained metallic interfaces is an attractive option for preparing highly ordered nanotemplates. The great potential of this natural templating approach is that symmetry, feature sizes, and density are predicted to depend on the interfacial stress in these strained layers, which can be adjusted by changing the substrate-thin film composition, temperature, a...
One of the principal economic drivers for the semiconductor industry is high performance, low power applications for the portable electronics consumer market. Unfortunately, the power dissipation resulting from the use of conventional CMOS technology in this area is becoming a critical design issue. Supply voltage reduction has been the preferred technique for reducing power dissipation. Howeve...
