A cellular receptor for erythroid differentiation factor (EDF) was demonstrated by incubation of 125I-labeled EDF with rat follicular granulosa cell cultures. The specific binding of labeled EDF to the cells showed saturation; Scatchard analysis of binding data indicated a single class of receptors having Kd = 3.4 x 10(-10) M. A large excess of unlabeled EDF reduced labeled EDF binding almost c...

This study gives strategies for estimating the modified Allan variance (MVAR), and formulas for computing the equivalent degrees of freedom (edf) of the estimators. A thirddifference formulation of MVAR leads to a tractable formula for edf in the presence of power-law phase noise. The effect of estimation stride on edf is shown. First-degree rational-function approximations for edf are derived,...

Event representation models provide a framework in which we can reason about events so as to interpret the collective behaviour of objects over time and space domains. Many are context-specific and lack flexibility when faced with unstructured video. In the past many efforts have been made to define a comprehensive event description framework (EDF), which can provide a framework to develop onto...

Earliest deadline first (edf) is a widely used algorithm for online deadline scheduling. It has been known for long that edf is optimal for scheduling an underloaded, single-processor system; recent results on the extra-resource analysis of edf further revealed that edf when using moderately faster processors can achieve optimal performance in the underloaded, multi-processor setting. This pape...

The newly discovered extracellular death factor (EDF) is a pentapeptide with the sequence NNWNN in Escherichia coli. It was reported that it participated in the cell death process mediated by toxin-antitoxin system mazEF. Reactive oxygen species (ROS) are recently considered as common factors for bactericidal antibiotics-mediated cell death. Previous study indicated that EDF could scavenge hydr...

In this paper we are going to analyze and trying to compare EDF and LLREF scheduling algorithms, used in multiprocessor platforms. We will briefly describe classic EDF, global EDF, which is an extension of EDF, and the newer LLREF algorithm. Then we will analyze the ability of global EDF in scheduling task sets in random manner and compare with the LLREF one, which can schedule any task set whe...

UNLABELLED Eshcerichia coli mazEF is a stress-induced toxin-antitoxin module mediating cell death and requiring a quorum-sensing (QS) extracellular death factor (EDF), the pentapeptide NNWNN. Here we uncovered several distinct molecular mechanisms involved in its generation from the zwf mRNA encoding glucose-6-phosphate dehydrogenase. In particular, we show that, under stress conditions, the en...

Real-time communication is important for time-critical multimedia applications. However, conventional real-time schedulers such as EDF (Earliest Deadline First) and RM (Rate Monotonic) are designed for task sets with sophisticated characteristics. They can perform well in the idea network with precise workloads. But, in a realistic network with shared bandwidth and unpredictable workloads, thei...

This paper proposes distributed evolutionary digital filters (EDFs). The EDF is an adaptive digital filter which is controlled by adaptive algorithm based on evolutionary computation. In the proposed method, a large population of the original EDF is divided into smaller subpopulations. Each sub-EDF has one subpopulation and executes the small-sized main loop of the original EDF. In addition, th...
