The ability to synthesize arrays of related compounds quickly and with good purity has become critical for a rapid exploration their properties biological or material applications. While number methods have been developed enable this combinatorial synthesis, the existing options were not readily appliable synthesis aurones using simple Knoevenagel condensation approach. In order avoid time, exp...
Understanding how people view flash flood risks can help improve risk communication, ultimately improving outcomes. This article analyzes data from 26 mental models interviews about flash floods with members of the public in Boulder, Colorado, to understand their perspectives on flash flood risks and mitigation. The analysis includes a comparison between public and professional perspectives by ...
Flash memory has gained tremendous popularity in recent years. A variant of flash, referred to as NAND flash, is widely used in consumer electronics products, such as cell-phones and music players while NAND flash based Solid-State Disks (SSDs) are increasingly displacing hard disk drives as the primary storage device in laptops, desktops, and even data centers. Computer architects have recentl...
FLICE/caspase-8-associated huge protein (FLASH)/casp8ap2 is involved in various cellular functions, such as cell cycle progression, transcriptional regulation, the regulation of apoptosis, and the regulation of histone gene expression. The down-regulated expression of FLASH has been shown to inhibit cell cycle progression in the S phase in many kinds of mice and human cell lines and the inhibit...
While disks have offered a stable behavior for decades thus guaranteeing the timelessness of many database design decisions, flash devices keep on mutating. Their behavior varies across models and across firmware updates for the same model. Many researchers have proposed to adapt database algorithms for existing flash devices; others have tried to capture the performance characteristics of flas...
Parietal and premotor cortices of the macaque monkey contain distinct populations of neurons which, in addition to their motor discharge, are also activated by visual stimulation. Among these visuomotor neurons, a population of grasping neurons located in the anterior intraparietal area (AIP) shows discharge modulation when the own hand is visible during object grasping. Given the dense connect...
According to current accounts, the perceived location of a target flash presented in the dark around the time of a saccade comes largely from an extraretinal signal that begins to change before, and continues to change during and following the saccade. Opposed to this view, this study offers a model suggesting that the perception of a single flash or two successive flashes in association with a...
The ubiquitous Flash platform enables programmers to build sophisticated web application “mash-ups” that combine Flash executables loaded from multiple trust domains with complex, asymmetric trust relationships. Flash provides APIs and run-time checks to help programmers declare and enforce trust relationships between different domains, but there is currently no formal security model for Flash....
The paper presents an advanced Fuzzy self-tuning PID controller theory and it implement its applications on Data I/O’s automated robotic programming systems. Considerable programming technology shift occurred in recent device programmer industry; programming density have been constantly fast growing from lowvolume to high-volume programming for all kinds of non-volatile flash memory devices suc...
The aim of this article is to familiarize the user with the Web publishing of the files obtained by Flash. The article contains an overview of Macromedia Flash 5, as well as the running of a Playing Flash movie, information on Flash and Generator, the publishing of Flash movies, a HTLM publishing for Flash Player files and publishing by Generator templates. 1. General presentation of Macromed...
