A review of infrared readout electronics for space science sensors is presented. General requirements for scientific IR FPA readout are discussed. Specific approaches to the unit cell electronics are described with respect to operation, complexity, noise and other operating parameters. Recent achievements in IR FPA readout electronics are reviewed. Implementation technologies for realization of...

The aim of the study was an evaluation of fluorescence polarisation assay (FPA) as a potential tool improving specificity of serological diagnosis of brucellosis in pigs. The evaluation was done by comparing the results of FPA with the results of rose bengal test (RBT), serum agglutination test (SAT), complement fixation test (CFT) and ELISA when false positive sera were tested. One hundred nin...

To provide more information on the pathways of fibrinogen catabolism in generalized cancer, the effect of heparin on fibrinopeptide A (fpA) and on 125I-fibrinogen kinetics was studied in 15 patients with disseminated neoplasia. Three patients had evidence of venous thrombosis and in 2 additional patients a low fibrinogen level together with increased amounts of FDP/fdp and a positive ethanol te...

This paper proposes a novel evolutionary optimization technique referred to the flower pollination algorithm (FPA) for system identification. The optimal parameters of an unknown infinite impulse response (IIR) system are computed using FPA. This algorithm is inspired by the pollination process of flowers. Proper tuning of control parameter has been performed in order to accomplish a balance be...

Tanami, Yoh (University of Texas Medical Branch, Galveston) and Morris Pollard. Effect of p-fluorophenylalanine on psittacosis virus in tissue cultures. J. Bacteriol. 83:437-442. 1962.-The inhibitory effect of p-fluorophenylalanine (FPA) on maturation of psittacosis virus was investigated, with attention to the time sequence of viral protein synthesis. Extracellular virus particles were not ina...

The amino acid antimetabolite, DL-p-fluorophenylalanine (FPA), inhibited induction of flowering in the short-day cocklebur plant, Xanthium pensylvanicum Wall., primarily by interfering with processes occurring during the inductive dark period. At the concentrations used the inhibitor had little effect on subsequent vegetative development of the plant.The inhibition was largely reversed (interna...

This paper describes recent developments and the current status of the Laser Diode Array Projector (LDAP) Technology. The LDAP is a state-of-the-art dynamic infrared scene projector system capable of generating high resolution in-band infrared imagery at high frame rates. Three LDAPs are now operational at the US Army Aviation and Missile Command's (AMCOM) Missile Research, Development, and Eng...

BACKGROUND Thrombolytic therapy induces a procoagulant state characterized by elevated plasma levels of fibrinopeptide A (FPA), but the responsible mechanism is uncertain. METHODS AND RESULTS Washed plasma clots were incubated in citrated plasma in the presence or absence of tissue plasminogen activator (t-PA), and FPA generation was monitored as an index of unopposed thrombin activity. FPA l...

Rockwell has begun developing infrared FPAs in the 2048 format. The first is the HAWAII-2, an infrared 2048 focal plane array (FPA) for next-generation infrared astronomy. It will supplant our HAWAII 1024 as the largest high-performance infrared imager available. As with our prior infrared FPAs, the flip-chip hybrid will consist of a low dark current, low-capacitance HgCdTe detector array mated...

* Here, a new approach to macromolecular imaging of leaf tissue using a multichannel focal plane array (FPA) infrared detector was compared with the proven method of infrared mapping with a synchrotron source, using transverse sections of leaves from a species of Eucalyptus. * A new histological method was developed, ideally suited to infrared spectroscopic analysis of leaf tissue. Spatial reso...
