A purified murine lymphokine, eosinophil differentiation factor (EDF), was found to be a selective stimulus for the clonal proliferation and differentiation of murine eosinophil progenitor cells, establishing it as the murine eosinophil colony-stimulating factor (Eo-CSF). EDF was also active on human eosinophil progenitors and mature blood eosinophils, but had no effect on neutrophil or macroph...

The aim of our study was to review the literature on the relationship between executive dysfunction (EDF) and the behavioral and psychological symptoms of dementia (BPSD). We searched for papers that addressed one or both of two questions: a) is there a causal relationship between EDF and BPSD?; b) What are the main hypotheses or theoretical models that explain this relationship? A systematic s...

This work describes improved methods and algorithms for implementing extended depth of field (EDF) microscopy through point spread function (PSF) engineering. It utilizes adaptive optics to create a test bed on which to evaluate new phase shapes for EDF. Being able to quickly and cheaply design novel PSFs is essential to overcome limitations of EDF that have prevented the technology from reachi...

Improvements in schedulability tests for global fixed-priority and EDF scheduling in a homogeneous multiprocessor (symmetric multiprocessing) environment have shown that the worst-case guaranteed achievable utilization levels for global EDF scheduling equals what can be achieved with partitioned scheduling, and both ways of applying EDF scheduling out-perform fixed-priority scheduling, for sets...

Activin A/erythroid differentiation factor (EDF), a dimeric polypeptide hormone composed of two beta A subunits, regulates growth and erythroid differentiation of human hematopoietic progenitor and erythroleukemia cells. We have identified activated human peripheral blood monocytes as a natural source of activin A/EDF. In these cells, lipopolysaccharide (LPS) induced rapidly the expression of t...

Scheduling real-time systems on multiprocessors introduces complexities that do not arise when using uniprocessors. If the processors do not all operate at the same speed, scheduling becomes even more complex. When scheduling using EDF on multiprocessors, breaking deadline ties in different ways can change the resulting schedule dramatically. We consider methods to resolve the ambiguities in ED...

In this paper, wepresent a comparative study on temperature-dependent spectroscopic characteristics and L-band amplifier performance for aluminum-rich erbium-doped fiber (EDF) in-house fabricated phosphorus co-doped EDF. Different pumping configurations were studied to conclude that the pump wavelength of 980 nm with unequal forward/backward powers exhibited better temperature stability. Phosph...

Generalized Processor Sharing (GPS) has gained much popularity in recent years as a simple and effective scheduling mechanism for the provisioning of Quality of Service (QoS) in emerging high-speed networks. For supporting deterministic end-to-end delay guarantees, GPS is known to be sub-optimal in comparison to the Earliest Deadline First (EDF) scheduling discipline; nevertheless it is often p...

This paper proposes a QoS-Aware Optical Connection Setup Management scheme that uses the Earliest Deadline First (EDF) queueing discipline to schedule the setup of the optical connections. The benefits of this EDF-based scheme are twofold: a) it reduces the blocking probability since blocked connection requests due to resource unavailability are queued for possible future setup opportunities an...

EDF (Early Deadline First) algorithm is a very important scheduling algorithm for realtime systems . The EDF algorithm assigns priorities to each job according to their absolute deadlines and has good performance when the real-time system is not overloaded. When the real-time system is overloaded, many misdeadlines will be produced. But these misdeadlines are not uniformly distributed, which us...
