The Polar Format Algorithm (PFA) is suitable for spotlight synthetic aperture radar (SAR) image focusing either in monostatic or bistatic cases. The classic linear-trajectory PFA complete data correction in wavenumber domain, converting data from the polar format to the rectangular format. However, the twodimension processing (either using interpolation or chirp-z transform) introduces heavy co...

Thermal stability of cation exchange, PFA-g-polystyrene sulfonic acid membranes prepared by radiation-induced graft copolymerization of styrene onto PFA films followed by sulfonation was studied by thermal gravimetric analysis (TGA) and oven heat treatment. The tested samples included original and grafted PFA films as reference materials. All the membranes showed multistep decomposition pattern...

A Glu-89-->Gly alteration in the human immunodeficiency virus type 1 reverse transcriptase (RT) was previously shown to result in resistance to several dideoxynucleoside analogs and to phosphonoformic acid (PFA; foscarnet). This residue was altered to Ala, Val, Ser, Thr, Gln, Asp, Asn, or Lys, and the ddGTP and PFA sensitivities of the mutant RTs were measured. Replacements with Ala, Gly, Val, ...

The platelet function analyzer PFA-100 (Dade International Inc., FL, USA) is a relatively novel method for rapid in vitro global evaluation of primary hemostasis.1 Since the PFA-100 has been shown to be very sensitive to platelet and von Willebrand factor (VWF) levels and function, it is useful mainly as a screening test for von Willebrand’s disease (VWD) and several platelet disorders.2,3 Rece...

BACKGROUND Improvement in swimming performance involves the dynamic alignment of the body in liquid, technical skill, anthropometric characteristics of athletes, and the ability to develop propulsive force. The aim of this study was to assess the relationships between the propulsive force during swimming and arm muscle area (AMA) and propose an equation to estimate the propulsive force in young...

Several important physiological transactions, including control of replicative life span (RLS), prevention of collision between replication and transcription, and cellular differentiation, require programmed replication fork arrest (PFA). However, a general mechanism of PFA has remained elusive. We previously showed that the Tof1-Csm3 fork protection complex is essential for PFA by antagonizing...

Mass customization is becoming an important agenda in industry and academia alike. This paper deals with mass customization from a product development perspective. A framework of design for mass customization (DFMC) by developing product family architecture (PFA) is presented. To deal with tradeoffs between diversity of customer requirements and reusability of design and process capabilities, D...

Mutants of herpes simplex virus type 1, resistant to phosphonoformate (PFA) and phosphonoacetate (PAA), have been selected in cell culture. The PFAresistant mutant (HSV-PFAr) and the PAA-resistant mutant (HSV-PAAr) were also resistant to PAA and PFA, respectively. This cross-resistance indicates that PFA and PAA interact at the same site. The HSV-PFAr had a decreased susceptibility to vidarabin...

Profunda femoris artery (PFA) pseudoaneurysm after blunt trauma without associated femur fracture is a rare occurrence. Most of the reported cases of PFA pseudoaneurysm in the English literature developed after penetrating trauma, surgical procedures, and femur fractures. We present two such cases following blunt trauma and without any associated long bone injury. After initial imaging failed t...

IT usage is generally viewed as a key indicator of adoption success and a prerequisite for deriving benefits. Yet, while IT usage can provide a good measure of adoption success, it does not necessarily yield desirable outcomes, i.e., the individual benefits expected by its designers. This paper investigates how IT use leads to its desirable outcomes based on a functional affordance (FA) perspec...
