Dynamics of 3D SUSY Gauge Theories with Antisymmetric Matter
No full textAbstract We investigate the IR dynamics of N = 2 SUSY gauge theories in 3D with antisymmetric matter. The presence of the antisymmetric fields leads to further splitting of the Coulomb branch. Counting zero modes in the instanton background suggests that more than a single direction along the Coulomb branch may remain unlifted. We examine the case of SU (4) with one or two antisymmetric fields and various flavors in detail. Using the results for the corresponding 4D theories, we find the IR dynamics of the 3D cases via compactification and a real mass deformation. We find that for the s-confining case with two antisymmetric fields, a second unlifted Coulomb branch direction indeed appears in the low-energy dynamics. We present several non-trivial consistency checks to establish the validity of these results. We also comment on the expected structure of general s-confining theories in 3D, which might involve several unlifted Coulomb branch directions

Get PDFAbstract: Optical frequency domain imaging (OFDI) in the 800-nm biological imaging window is demonstrated by using a novel wavelengthswept laser source. The laser output is tuned continuously from 815 to 870 nm at a 43.2-kHz repetition rate with 7-mW average power. Axial resolution of 10-μm in biological tissue and peak sensitivity of 96 dB are achieved. In vivo imaging of Xenopus laevis is demonstrated with an acquisition speed of 84 frames per second (512 axial lines per frame). This new imaging technique may prove useful in comprehensive retinal screening for medical diagnosis and contrast-agent-based imaging for biological investigations.

Corrosion Inhibition of Mild Steel in Citric Acid by Aqueous Extract of Piper Nigrum L
Get PDFAbstract: The inhibition efficiency (IE) of an aqueous extract of Piper Nigrum L. in controlling corrosion of mild steel at pH 12 has been evaluated by weight loss method in the absence and presence of inhibitor in citric acid medium at different concentration. The result showed that the corrosion inhibition efficiency of these compounds was found to vary with the different concentration at two hour time interval at room temperature. Also, it was found that the corrosion inhibition behaviour of Piper Nigrum L. is greater in 2 N Citric acid than 1 N Citric acid medium. So Piper Nigrum L. can be used has a good inhibitor for preventing mild steel material which is used in many construction purpose
MATHEMATICAL MODEL FOR HIV AND CD4+ CELLS DYNAMICS IN VIVO
No full textAbstract: Mathematical models are used to provide insights into the mechanisms and dynamics of the progression of viral infection in vivo. Untangling the dynamics between HIV and CD4+ cellular populations and molecular interactions can be used to investigate the effective points of interventions in the HIV life cycle. With that in mind, we develop and analyze a stochastic model for In-Host HIV dynamics that includes combined therapeutic treatment and intracellular delay between the infection of a cell and the emission of viral particles. The unique feature is that both therapy and the intracellular delay are incorporated into the model. We show the usefulness of our stochastic approach towards modeling combined HIV treatment by obtaining probability generating function, the moment structures of the healthy CD4+ cell, and the virus particles at any time t and the probability of virus clearance. Our analysis show that, when it is assumed that the drug is not completely effective, as is the case of HIV in vivo, the predicted rate of decline in plasma HIV virus concentration depends on three factors: the initial viral load before therapeutic intervention, the efficacy of therapy and the length of the intracellular delay

Get PDFApplication of Portable CDA for Secure Clinical-document Exchange
Get PDFAbstract Health Level Seven (HL7) organization published the Clinical Document Architecture (CDA) for exchanging documents among heterogeneous systems and improving medical quality based on the design method in CDA. In practice, although the HL7 organization tried to make medical messages exchangeable, it is still hard to exchange medical messages. There are many issues when two hospitals want to exchange clinical documents, such as patient privacy, network security, budget, and the strategies of the hospital. In this article, we propose a method for the exchange and sharing of clinical documents in an offline model based on the CDA-the Portable CDA. This allows the physician to retrieve the patient's medical record stored in a portal device, but not through the Internet in real time. The security and privacy of CDA data will also be considered
A Nondominated Sorting Genetic Algorithm for Sustainable Reverse Logistics Network Design
Get PDFAbstract Determining the appropriate strategy in recycling method that will has less pollution besides the economical process, has been signified as one of the basic principles for achieving sustainability in the supply chain due to the new legislation, environmental concerns' growth, increase volume of returns, etc. in recent years. Here will be considered a design of reverse network development for recycling waste products besides the reduction of harmful emissions due to storage, transportation and various processes. The purpose of this study investigates a multi objective optimization problem of sustainable Reverse logistics network design with the aim of management in allocating customers by coordinating facilities to ensure minimum cost as well as the environmental impact. In this work is presented a dynamic linear programming model which examines the important aspects for the design and strategic planning of a sustainable chain. Due to the complexity and differences in the nature of the model objectives, is proposed a heuristic method based nondominated sorting genetic algorithm to solve the problem. Finally, the results are discussed and analyzed

No full textAbstract The influence of electrical field strength and number of pulses on cell rupture of onion tissues was investigated by two different methods to understand the changes in cell viability of plant tissues after pulsed electric field (PEF) treatment. The impact of pulsed electric field parameters on cell integrity of 20 mm diameter, 4 mm thick disks of Sabroso onions (Allium cepa L.) was determined by ion leakage measurements and microscopic method. The effect of treatments on cellular integrity was visualized by neutral red staining of the onion cells. Cell rupture is essential for optimal process design before extraction of desirable compounds and/or drying of plant tissues. Experimental results were obtained for onion disks treated with electrical pulses at field strengths of E≈ 167 V/cm and 333 V/cm, pulse width of ti=100 µs, frequency of f=1 Hz and the number of pulses, n=1 to 100. At 167 V/cm electric field strength treatment cell rupture was not observed however ion leakage increased and air spaces around cell walls disappeared, most likely due to changes in cell membrane permeability. Irreversible cell rupture occurred at 333 V/cm. Ion leakage values and ruptured cells count was increased with increasing pulse number. 92.2±5.9 % of the onion cells were ruptured after 333 V/cm and 100 pulse treatment. Small plant cells that are located near vascular bundles and upper epidermis showed higher resistance to pulsed electric field treatments. 1 A C C E P T E D M A N U S C R I P T ACCEPTED MANUSCRIPT Keywords: pulsed electric fields, plant tissue structure, onion, neural red staining, ion leakage Industrial Relevance: The aim of this study was to determine the response of plant tissues with different cell type to the pulse electric field treatment. Two different methods, neutral red staining and ion leakage, were used to visualize and determine the cell rupture on onion tissues. Industry may choose one of these methods to evaluate treatment efficiency on the basis of cell rupture; especially ion leakage measurements which require lower investment cost and easy to apply or microscopic method for visualize the cells layer by layer. The paper stresses the importance of cell type, size and distribution of cells were found to the ability to resist cell rupture during pulsed electric field treatment. It is critical to explain overall changes caused by PEF on the structure of plant tissue at a cellular level in order to optimize the quality of PEF processed foods
