This paper investigates the usefulness of PSF in software engineering and reengineering. PSF is based on ACP (Algebra of Communicating Processes) and as some architectural description languages are based on process algebra, we investigate whether PSF can be used at the software architecture level, but we also use PSF at lower abstract levels. As a case study we reengineer the compiler from the ...

We present a discussion of the methods that can be used to model the JWST Point Spread Function (PSF) and illustrate some of the potential impacts of the PSF properties on the scientific performance of the telescope. We summarize the quantitative PSF measurements typically used in astronomical imaging and evaluate those quantities on model NIRCam PSFs. These PSFs are generated using optical pat...

objective(s): the present study was conducted to examine whether the standardized uptake value (suv) may be affected by the spatial position of a lesion in the radial direction on positron emission tomography (pet) images, obtained via two methods based on time-of-flight (tof) reconstruction and point spread function (psf). methods: a cylinder phantom with the sphere (30mm diameter), located in...

PSF is considered to have multiple functions in RNA processing, transcription and DNA repair by mitotic recombination. In the present study, we found that PSF is produced in spermatogonia, spermatocytes and spermatids, suggesting that PSF may also function in meiotic recombination. We tested the effect of PSF on homologous pairing by the meiosis-specific recombinase DMC1, and found that human P...

Peroxisome proliferator-activated receptor gamma (PPARγ) is a nuclear receptor that plays an essential role in cell proliferation, apoptosis, and inflammation. It is over-expressed in many types of cancer, including colon, stomach, breast, and lung cancer, suggesting that regulation of PPARγ might affect cancer pathogenesis. Here, using a proteomic approach, we identify PTB-associated splicing ...

Abstract Surface positve-charged composite membranes were prepared through two guanidine group containing polymers, polyhexamethylene (PHMG) and biguanidine (PHMB). They used as aqueous phase monomers in an interfacial polymerization (IP) process reacting with trimesoyl chloride (TMC) on the surface of polysulfone (Psf) ultrafiltration membrane. Piperazine (PIP) provided best pH adjustment amon...

Many conventional blind image deconvolution algorithms have much processing time because the consideration of various cases and the optimization are required for general employment. Moreover, these algorithms are also complex to deal with various point spread functions (PSF). Therefore, this paper restricts the type of PSF to the dual-exposure type and proposes effective PSF search algorithm, u...

A glycoprotein that stimulates the proliferation of multiple hemopoietic stem and progenitor cell types was purified to apparent homogeneity. The factor, termed P cell-stimulating factor (PSF), was assayed by its ability to support the growth of murine factor-dependent hemopoietic cell lines operationally termed persisting cells (P cells). PSF was purified 50,000-fold from serum-free medium con...

The effects of preparation parameters on the performance and morphology of polydimethylsiloxane/ polysulfone (PDMS/PSf) membranes were investigated. The PDMS layer is mainly used for sealing the defects of the PSf selective layer. The membrane morphologies were characterized by using scanning electron microscopy (SEM). The CO2/CH4 separation performance of membranes was studied by a pure gas pe...
