DMA : a diabetes disease management system
There is a clear and present need to improve the quality of diabetes care. Information technology can be used as a means to that end. In this article, we discuss the design and implementation of a web-based diabetes application. We show the role of modeling clinical workflow in the design …

Performance portfolio Steven Adam Frey DMA 2015
… realm, it continues to not gain traction. This DMA portfolio contains some of the most substantial works and projects that aim to propel the euphonium into the coveted orchestral sphere. By elevating the instrument to the solo role with the symphony orchestra, the euphonium gains credibility and …

Modeling and Synthesis of Linux DMA Device Drivers using HOL4
… systems utilize Direct Memory Access (DMA) controllers, where peripherals (such as network interfaces and USB devices) can access memory independently of the CPU, improving transfer speeds. However, this bypass also introduces security vulnerabilities if the DMA controller is not …

Worst-Case Timing Analysis of Concurrently Executing DMA I/O and Programs
A cycle-stealing DMA I/O task is allowed to proceed only when the CPU does not need the system bus. As a result, the execution time of a cycle-stealing DMA I/O task is affected by a set of CPU tasks which execute concurrently with the I/O task. We discuss the problem of bounding the WCET of a …

The Antitumor Agent, Arglabin-DMA, Preferentially Induces Apoptosis in Human Colon Tumor Cells
<p>Arglabin-DMA, an analog of farnesyl pyrophosphate (FPP), reportedly inhibits farnesyltransferase (FTase) directly by competitively blocking the binding of Ras protein and its posttranslational modification, as suggested in previous studies. But, the mechanisms by which Arglabin-DMA inhibits …

Cellular Mechanism of Arglabin-Dimethylaminohydrochloride Cytotoxicity
… Arglabin-dimethylaminohydrochloride (arglabin-DMA) represents one of the new classes of anti-cancer agents that have shown promise in suppressing the growth of various tumor cells. However, the cellular mechanism of arglabin-DMA cytotoxic effects on tumor cells is still unclear. The current …

Verification of DMAC Device Driver Operations in HOL4
… to do. To solve this, Direct Memory Access (DMA) is used, which allows peripherals and other hardware accelerators, such as stand-alone DMA Controllers (DMACs), to read and write memory without CPU intervention. However, DMA introduces security problems in which attackers are able to leak …

Tandem differential mobility analyzer studies and aerosol volatility
… performance of a Differential Mobility Analyzer (DMA) for diffusing particles; the first measurements of the transfer function for a specific type of cylindrical DMA used extensively at the University of Missouri-Rolla (UMR); and the application of a tandem DMA (TDMA) to characterize the …

Arsenic in drinking water caused ultra-structural damage in urinary bladder but did not affect expression of DNA damage repair genes or repair of DNA damage in transitional cells
… has only been observed in dimethylarsinic acid [DMA(V)]-exposed F344 rats. The goal of the present studies was to investigate inhibition of DNA repair as a mode of action for arsenic carcinogenesis/ cocarcinogenesis in the urinary bladder. Methods were first developed to harvest only transitional …

A Study of Disk Performance Optimization.
… of PCI bus mastering Direct Memory Access (DMA) on the performance of systems with IDE drives. DMA is a data transfer protocol that allows data to be sent directly from an attached device to a computer system’s main memory, thereby reducing CPU overhead. PCI bus mastering allows modern IDE …

Application of Thermomechanical Characterization Techniques to Bismuth Telluride Based Thermoelectric Materials
… In this paper, dynamic mechanical analysis (DMA) and differential scanning calorimetry data for bismuth telluride based TE materials is presented. The TE materials' tan delta values, indicative of viscoelastic energy dissipation modes, approached that of glassy or crystalline polymers, were …

Structural Behavior of Nitinol Microflaps
Finite element models of the SMAT microflap and DMA specimens were created by incorporating a user material subroutine SMA-UMAT in ABAQUS. Model results were verified by correlation with the DMA experimental results. The structural behavior of a SMAT microflap was then analyzed and the results were …

Dynamic mechanical analysis of graphite/epoxy composites with varied interphases
Dynamic mechanical analysis (DMA) has been used extensively to characterize polymeric materials. This thesis investigates the use of this technique to characterize composite materials. Four material systems, all having the same fiber and the same matrix material, were systematically altered with …
