Resource utilization model for the algorithm to architecture mapping model

The analytical model for resource utilization and the variable node time and conditional node model for the enhanced ATAMM model for a real-time data flow architecture are presented in this research. The Algorithm To Architecture Mapping Model, ATAMM, is a Petri net based graph theoretic model developed at Old Dominion University, and is capable of modeling the execution of large-grained algorithms on a real-time data flow architecture. Using the resource utilization model, the resource envelope may be obtained directly from a given graph and, consequently, the maximum number of required resources may be evaluated. The node timing diagram for one iteration period may be obtained using the analytical resource envelope. The variable node time model, which describes the change in resource requirement for the execution of an algorithm under node time variation, is useful to expand the applicability of the ATAMM model to heterogeneous architectures. The model also describes a method of detecting the presence of resource limited mode and its subsequent prevention. Graphs with conditional nodes are shown to be reduced to equivalent graphs with time varying nodes and, subsequently, may be analyzed using the variable node time model to determine resource requirements. Case studies are performed on three graphs for the illustration of applicability of the analytical theories

The Cluster Multipole Algorithm for Far-Field Computations

Computer simulations of N-body systems are beneficial to study the overall behavior of a number of physical systems in fields such as astrophysics, molecular dynamics, and computational fluid dynamics. A new approach for computer simulations of N-body systems is proposed in this research. The new algorithm is called the Cluster Multipole Algorithm (CMA). The goals of the new algorithm are to improve the applicability to non-point sources and to provide more control on the accuracy over current algorithms. The algorithm is targeted to applications that do not require rebuilding the data structure about the system every time step due to current limitations in the construction of the data structure. Examples of slowly changing systems can be found in molecular dynamics, capacitance, and computational fluid dynamics simulations. As the data structure development is improved, the new algorithm will be applicable to a wider range of applications. The CMA exhibits the flexibility of both Appel\u27s algorithm and the Fast Multipole Method (FMM) without sacrificing the order of computation (O(N)) for well structured clusters. The CMA provides more control on the accuracy of computations as compared to both the FMM and Appel\u27s algorithm resulting in enhanced performance. A set of requirements are imposed on the data structures which are applicable, to maintain O(N) computation. However, the algorithm is capable of handling a wide range of data structures beyond the FMM

The challenge of online learning for medical education during the COVID-19 pandemic

The global impact of the COVID-19 pandemic on education systems across the world has led to major and rapid changes in the provision of higher and medical education, with increasing delivery of the curriculum by online approaches. A recent synthesis of the global responses by universities to the COVID-19 pandemic noted that the majority of universities were using online learning, but with differences between countries in the rapidity and extent of the shift.1 These differences were attributed to the available resources, which included previous experience of using online learning and the availability of technology. However, the authors also noted that there were similar differences within countries and they highlighted that the current and urgent challenge for all universities was to ensure that the educational potential of online learning was optimised in each university. This is an important message that is also highly relevant to all medical education providers, from basic (undergraduate) to postgraduate and continuing. The editorial highlights the importance of iteratively designing online learning to ensure that the development, delivery and implementation of online learning are optimised to a specific local context. In addition, the editorial discusses the importance of medical educators sharing their approaches in designing online learning

KAP study of contraception in clients undergoing MTP and sterilization in Gujarat, India

Background: Lack of awareness, knowledge and education, religious beliefs and fear of side effects are the main causes why women do not use family planning methods. To study the knowledge, attitude and practice of contraception among clients undergoing to Medical termination of pregnancy (MTP) and sterilization.Methods: This prospective study was done among 400 indoor cases at Department of Obstetrics and Gynecology in B.J. Medical college, Ahmedabad during July 2002 to October 2003. All the clients undergoing MTP and sterilization were explained and counseled about contraception with GATHER approach of family planning. After taking detail history, a thorough clinical examination of the clients was carried out with preliminary investigations.Results: Almost 58% clients were willing to accept TL method as contraceptive option, 39.5% IUCD, 1.75% OC pill method of contraception. Regarding history of side effect of contraceptive use, 17.3% condom users, 68.5% OC pill users, 63% CuT users have felt side effect. Almost 42.5% clients were operated by MTP + Lap TL, 39.5% by MTP + CuT and 14.5% by plain Lap TL.Conclusions: Efforts should be made to promote information, education and communication regarding emergency contraception targeted to all women of reproductive age group. It is important that unwanted pregnancy be prevented through effective contraceptive practice rather than abortion

Formulation and evaluation of transdermal patch of Aceclofenac

The purpose of this research was to develop a matrix-type transdermal therapeutic system containing drug Aceclofenac with different ratios of hydrophilic (hydroxyl propyl cellulose) and hydrophobic (ethyl cellulose) polymeric systems by the solvent evaporation technique by using 15 % w/w of dibutyl phthalate to the polymer weight, incorporated as plasticizer. Different concentrations of oleic acid and isopropyl myristate were used to enhance the transdermal permeation of Aceclofenac. The physicochemical compatibility of the drug and the polymers studied by differential scanning calorimetry and infrared spectroscopy suggested absence of any incompatibility. Formulated transdermal films were physically evaluated with regard to thickness, weight variation, drug content, flatness, tensile strength, folding endurance, percentage of moisture content and water vapour transmission rate. All prepared formulations indicated good physical stability. In-vitro permeation studies of formulations were performed by using Franz diffusion cells. Formulation prepared with hydrophilic polymer containing permeation enhancer showed best in-vitro skin permeation through rat skin (Wistar albino rat) as compared to all other formulations. The results followed the release profile of Aceclofenac followed mixed zero-order and first-order kinetics in different formulation. However, the release profile of the optimized formulation F9 (r2 = 0.9935 for Higuchi) indicated that the permeation of the drug from the patches was governed by a diffusion mechanism. Formulation F9 showed highest flux among all the formulations and 1.369 fold enhancements in drug permeation. These results indicate that the formulation containing 15 % of oleic acid with 10 % Isopropyl myristate give better penetration of Aceclofenac through rat skin.Keywords: Aceclofenac, Transdermal Film, Permeation enhancer, In-vitro permeation study

Isoflavones and PPAR Signaling: A Critical Target in Cardiovascular, Metastatic, and Metabolic Disease

Isoflavone intake through foods and dietary supplements has both health advocates and critics. The latter come from a concern about the estrogenic effects of isoflavones in certain species. However, careful removal of isoflavones and other estrogens from the diet of rodents leads to the metabolic syndrome. These results suggest that isoflavones have other mechanisms of action, potentially those involving regulation of fatty acid metabolism via the nuclear receptors PPARα and PPARγ. The goal of this paper was to examine the evidence for isoflavone/PPAR signaling and to identify diseases in which such signaling would have an important impact. It is therefore of note that investigators using a chemical structure approach to discover PPAR ligands identified isoflavones as the best structures in the library of compounds that they tested. Future studies will involve careful identification of the underlying mechanisms whereby isoflavones have their action via PPAR signaling

Controlling Smartphone Webcam Mode Using Alternatives to Smartphone Touchscreen

This disclosure describes user-friendly techniques to connect a smartphone that is utilized as a web camera (webcam) by pairing the smartphone with a host device. Button-press patterns of a power button or another physical button on the side of a smartphone is used to convey user intent to enable/disable a webcam mode for the smartphone that is connected to a host device. This enables users to turn the webcam mode on/off even when the screen is turned off or facing away from the user, as is the case when a rear camera of the smartphone is used in the webcam mode. Alternatively, a companion wearable device can provide a user interface (UI) that can be utilized to perform control functions for a smartphone used as a webcam. The control functions can include turning the webcam mode on or off, providing real-time status of whether the smartphone is streaming video to the host device, and controlling parameters of the video captured by the smartphone, e.g., zoom, flash, active camera, quality, framerate, autoframing, focus, etc
