Although the quantum efficiencies of quantum dots (QDs) are approaching unity through advances in the synthesis of QD materials, their luminescence efficiencies after mixing with resin and thermal curing for white light-emitting diodes (LEDs) are seriously lowered because of aggregation and oxidation of QDs and poor adhesion of QDs to the resin. To overcome these problems, QD-layer-encapsulated...

In a structural error model the structural quasi score (SQS) estimator is based on the distribution of the latent regressor variable. If this distribution is misspecified the SQS estimator is (asymptotically) biased. Two types of misspecification are considered. Both assume that the statistician erroneously adopts a normal distribution as his model for the regressor distribution. In the first t...

ACCELERATED OPTIMIZATION ALGORITHMS FOR STATISTICAL 3D X-RAY COMPUTED TOMOGRAPHY IMAGE RECONSTRUCTION by Donghwan Kim Chair: Jeffrey A. Fessler X-ray computed tomography (CT) has been widely celebrated for its ability to visualize the anatomical information of patients, but has been criticized for high radiation exposure. Statistical image reconstruction algorithms in X-ray CT can provide impro...

Background The study was designed to evaluate and compare the effectiveness of 12-week open, closed and combined kinetic-chain exercises (OKCE, CKCE and CCE) on quadriceps muscle strength and thigh girth of patients with knee osteoarthritis (OA). Method The randomized clinical trial involved ninety-six consecutive patients with knee OA who were randomly assigned to one of OKCE, CKCE or CCE gr...

本稿では過負荷時にWeb アプリケーションサーバの性能低下を防ぐ Session-aware Queue Scheduling(SQS)を 提案する.既存の多くのアドミッション制御はサーバ全体またはページを単位として制御を行うため,セッション を利用する現実のワークロードには適していない.実際のワークロードを重視したスケジューリングを行うために, SQS ではページ単位のスケジューラとセッション単位のスケジューラを連携させる.ページスケジューラはWeb アプリケーションの進捗を監視することで,最適なページ処理並行度を動的に決定する.セッションスケジューラ はページスケジューラの待機リクエストのためのキューを監視することで最適な同時セッション数を動的に決定す る.我々はこれらのスケジューラを Tomcat 上に実装し,セッションを考慮したワークロードを用いて実験を行っ た.その結果,S...

There is an urgent need for the development of new drugs for the treatment of tropical parasitic diseases such as Chagas' disease and leishmaniasis. One potential drug target in the organisms that cause these diseases is sterol biosynthesis. This paper describes the design and synthesis of quinuclidine derivatives as potential inhibitors of a key enzyme in sterol biosynthesis, squalene synthase...

We present an efficient scheme to quickly generate three-qubit Greenberger–Horne–Zeilinger (GHZ) states by using three superconducting qubits (SQs) separated by two coplanar waveguide resonators (CPWRs) capacitively. The scheme is based on quantum Zeno dynamics and the approach of transitionless quantum driving to construct shortcuts to adiabatic passage. In order to highlight the advantages, w...
