We investigated whether human subjects' ability to identify the direction of a brief pulse of coherent motion in a random-dot pattern (RDP) was influenced by: (a) maintaining in working memory the direction of motion of an RDP previously presented far from the pulse (feature-based working memory or FBWM, Experiment 1), (b) attending to the direction of an RDP co-occurring with but far from the ...

The first fully synthetic glycopeptide vaccines against a fungal disease have been used to combat disseminated candidiasis in mice. Six T cell peptides found in Candida albicans cell wall proteins were selected by algorithm peptide epitope searches; each was synthesized and conjugated to the fungal cell wall beta-mannan trisaccharide [beta-(Man)(3)] by novel saccharide-peptide linker chemistry ...

Fructose 1,6-bisphosphate aldolase (FBA) is important for both glycolysis and gluconeogenesis in life. Class II (zinc dependent) FBA is an attractive target for the development of antibiotics against protozoa, bacteria, and fungi, and is also widely used to produce various high-value stereoisomers in the chemical and pharmaceutical industry. In this study, the crystal structures of class II Esc...

Hart, Beth A. (Cornell University, Ithaca, N.Y.), and Stanley A. Zahler. Lytic enzyme produced by Myxococcus xanthus. J. Bacteriol. 92:1632-1637. 1966.-Strain FBa of Myxococcus xanthus releases into its culture medium an enzyme capable of lysing Micrococcus lysodeikticus cells and of releasing N-acetyl amino sugars from their cell walls. The lysin is stable at pH values near neutrality and at t...

The Functional Bethe Ansatz (FBA) proposed by Sklyanin is a method which gives separation variables for systems for which an R-matrix is known. Previously the FBA was only known for SL(2) and SL(3) (and associated) R-matrices. In this paper I advance Sklyanin's program by giving the FBA for certain systems with SL(N) R-matrices. This is achieved by constructing rational functions A(u) and B(u) ...

Toward the extension of the light-harvesting region of sensitizers in dye-sensitized solar cells (DSSCs), two ethynyl-linked porphyrin trimers were synthesized and investigated. The zinc–freebase–zinc trimer (Zn–FbA–Zn) showed an absorption maximum at a longer wavelength than the all-zinc trimer (Zn–ZnA–Zn), although the energy level of Zn–FbA–Zn was lower than that of Zn–ZnA–Zn. The DSSCs usin...

This research has produced foamed glass-ceramics from coal fired power station furnace bottom ash (FBA) and soda-lime-silica glass. The as-received FBA was wet milled with different additions of resultant slurry dried formed into a powder. powder pressed sintered at range temperatures fluxing agent (sodium tetraborate decahydrate), bubble stabilising additive (tri-sodium phosphate) bloating (ca...

Modeling sophisticated biological systems in a way that makes them more apprehensible, without losing comprehension or robustness, is a challenging task. The flux balance analysis (FBA) model describes metabolic networks of single-celled organisms with the goal of simulating their steady-state behavior. FBA simulations yield reliable and biologically relevant growth rate values, but do not simu...

The most powerful genome-scale framework to model metabolism, flux balance analysis (FBA), is an evolutionary optimality model. It hypothesizes selection upon a proposed optimality criterion in order to predict the set of internal fluxes that would maximize fitness. Here we present a direct test of the optimality assumption underlying FBA by comparing the central metabolic fluxes predicted by m...

OBJECTIVE The aim of this study was to improve the understanding of FBA in children and to decrease the rate of misdiagnosis, missed diagnosis and morbidity. PATIENTS AND METHODS We analyzed the clinical features and the three-dimensional reconstructed CT images of 590 children with foreign body aspiration (FBA) in the Xuzhou area of the Jiangsu province. RESULTS CT imaging revealed common ...
