Protecting entanglement by adjusting the velocities of moving qubits inside non-Markovian environments
No full textEfficient entanglement preservation in open quantum systems is a crucial scope towards a reliable exploitation of quantum resources. We address this issue by studying how two-qubit entanglement dynamically behaves when two atom qubits move inside two separated identical cavities. The moving qubits independently interact with their respective cavity. As a main general result, we find that under resonant qubit-cavity interaction the initial entanglement between two moving qubits remains closer to its initial value as time passes compared to the case of stationary qubits. In particular, we show that the initial entanglement can be strongly protected from decay by suitably adjusting the velocities of the qubits according to the non-Markovian features of the cavities. Our results supply a further way of preserving quantum correlations against noise with a natural implementation in cavity-QED scenarios and are straightforwardly extendable to many qubits for scalability

Abstract
Introduction: The Diagnostic Radiology ward is one of the most important parts of a hospital that has an important role in the detection of various diseases. This sector has a lot ofstartup costs. Since this ward is an income-earning ward of the hospital, in order to improve thequality of diagnostic radiology and direct resources to the most productive uses, the performance of this sector should be considered as a necessity.
The aim of this study is estimation of technical efficiency of radiology wards of hospitals of Mashhad University of medicalsciences using data exhaustive analysis method.
Method: This research was conducted with a descriptive-analytical method in 2007 to 2011. The radiology wards of the hospitals of Mashhad University of medical sciences formed the study population. Theinput variable included number of personnel, physicians, equipment, and the output variables included income and the number of patients. The data were accumulatedby author-devised forms.
Results: Average of technical performance, managerial, and scale efficiency of the studied centers during the period of study was appointed 0.557, 0.942, and 0.567, respectively. The average technical performance efficiency of university hospitals' radiology wards wasless than that of other non-affiliated hospitals. Only one radiology part which runs by private sector has full performance during the study.
Conclusion: Centers which were more customer-oriented and tried more to comfort patients were more successful than other centers. Managers can increase motivation and thus efficiency by sharing income with some personnel.

Non-Markovianity and Coherence of a Moving Qubit inside a Leaky Cavity
No full textNon-Markovian features of a system evolution, stemming from memory effects, may be utilized to transfer, storage, and revive basic quantum properties of the system states. It is well known that an atom qubit undergoes non-Markovian dynamics in high quality cavities. Here we consider the qubit-cavity interaction in the case when the qubit is in motion inside a leaky cavity. We show that, owing to the inhibition of the decay rate, the coherence of the travelling qubit remains closer to its initial value as time goes by compared to that of a qubit at rest. We also demonstrate that quantum coherence is preserved more efficiently for larger qubit velocities. This is true independently of the evolution being Markovian or non-Markovian, albeit the latter condition is more effective at a given value of velocity. We however find that the degree of non-Markovianity is eventually weakened as the qubit velocity increases, despite a better coherence maintenance

The effect of angiparsTM on wound healing in patients with diabetes: A systematic review
No full textAbout 15% of patients with diabetes develop a Diabetic foot ulcer (DFU). It is an open sore or wound commonly located on the bottom of the foot. ANGIPARSTM is an Iranian-produced herbal remedy based on the extract of Melilotus officinalis. The aim of this study was to make a systematic review focused on determination of the effect of ANGIPARSTM on wound healing in patients with diabetes. The study was conducted in accordance with the PRISMA guidelines. Articles included in the review cover the period from the discovery of ANGIPARSTM to August 18, 2018. The data were analyzed using a descriptive method of Excel 2007 Software. Five articles with total number of 171 patients were included in the systematic review (SR) phase. In three articles, the methods were based on mm2 units and in the two others on cm2 units. Patients' follow-up varied from 4 weeks to 6 months after the intervention. In all patients, ANGIPARSTM responds well to the DFU disease. Due to the positive effect of the herbal drug, it is recommended to administer it for wound healing in patients with diabetes. © 2020, Islamic Azad University. All rights reserved

Dispelling the Myths Behind First-author Citation Counts
No full textWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods

Simulation of thermal plant optimization and hydraulic aspects of thermal distribution loops for large campuses
No full textFollowing an introduction, the author describes Texas A&M University and its utilities system. After that, the author presents how to construct simulation models for chilled water and heating hot water distribution systems. The simulation model was used in a $2.3 million Ross Street chilled water pipe replacement project at Texas A&M University. A second project conducted at the University of Texas at San Antonio was used as an example to demonstrate how to identify and design an optimal distribution system by using a simulation model. The author found that the minor losses of these closed loop thermal distribution systems are significantly higher than potable water distribution systems. In the second part of the report, the author presents the latest development of software called the Plant Optimization Program, which can simulate cogeneration plant operation, estimate its operation cost and provide optimized operation suggestions. The author also developed detailed simulation models for a gas turbine and heat recovery steam generator and identified significant potential savings. Finally, the author also used a steam turbine as an example to present a multi-regression method on constructing simulation models by using basic statistics and optimization algorithms. This report presents a survey of the author??s working experience at the Energy Systems Laboratory (ESL) at Texas A&M University during the period of January 2002 through March 2004. The purpose of the above work was to allow the author to become familiar with the practice of engineering. The result is that the author knows how to complete a project from start to finish and understands how both technical and nontechnical aspects of a project need to be considered in order to ensure a quality deliverable and bring a project to successful completion. This report concludes that the objectives of the internship were successfully accomplished and that the requirements for the degree of Degree of Engineering have been satisfied
