revised November 17, 1997 Rescattering E ects in Quarkonium Production1 Paul Hoyer and St ephane Peign e Nordita Blegdamsvej 17, DK{2100 Copenhagen , Denmark Abstract We study c and J= hadroproduction induced by multiple scattering o xed centres in the target. We determine the minimum number of hard scatterings required and show that additional soft scatterings may be factorized, at the level o...

OVERVIEW Mammalian memory involves multiple brain areas and neurotransmitter systems; both at the receptor and post-receptor level (Meneses, 2014a,b). Investigations of serotonin (5-hydroxytryptamine, 5-HT) involvement in memory (Meneses, 2013) have been significantly enhanced by the identification, classification, and cloning of multiple receptors (Hoyer et al., 1994, 2002) and studies at the ...

Hoyer, M. V.,j. Winn and D. E. Canfield,Jr. 2001. Citizenmonitoring ofaquatic bird populations using a Floridalake. Lake and Reserv. Manage. 17(2):82-89. Five years of monthly bird counts on a 2.32 km2 lake in north central Florida were used to examine the ability of a citizen volunteer to monitor aquatic bird populations. When compared to published aquatic bird data, collected by professional ...

A sign&ant advance in the study of animal viruses was marked by the work of Schwerdt and Schaffer (l), who first obtamed purified poliovirus in quantities sufficient to permit rigorous chemical and physical characterization. Their procedure, however, required large volumes of starting material, and was both lengthy and laborious. The development of suspension culture techniques (2) has provided...

Sparsity and entropy are pillar notions of modern theories in signal processing and information theory. However, there is no clear consensus among scientists on the characterization of these notions. Previous efforts have contributed to understand individually sparsity or entropy from specific research interests. This paper proposes a mathematical formalism, a joint axiomatic characterization, ...

Several renal diseases are believed to have an immune pathogenesis; the evidence includes depression of serum complement and the demonstration of the glomerular deposition of complement components and immunoglobulin by immunofluorescence. However, the congenital nephrotic syndrome and the nephritis associated with HenochSchonlein purpura (HSP) are two diseases in which the role of immunopathoge...

We have studied tertiary contacts in protofibrils and mature fibrils of amyloid-β (Aβ) peptides using solid-state NMR spectroscopy. Although intraresidue contacts between Glu-22 and Ile-31 were found in Aβ protofibrils, these contacts were completely absent in mature Aβ fibrils. This is consistent with the current models of mature Aβ fibrils. As these intramolecular contacts have also been repo...

The first well-recognized CBF studies on humans were performed by Kety and Schmidt in the 1940s using nitrous oxide (N2O) gas. The measurement of CBF was based on the principle that the rate of uptake and clearance of an inert diffusible gas is proportional to blood flow. The tissue concentration of the tracer at equilibrium must therefore be dependent on blood flow rather than diffusibility. T...
