Four stereoisomers of oxy-peptide nucleic acids containing ether linkages in the main chain and conformationally-restricted pyrrolidine rings (pyrrolidine-based oxy-PNA = POPNA) were newly synthesized and investigated for binding to DNA. cis-l-POPNA with 9 adenine bases formed the most stable hybrid with dT(9). The POPNA showed high sequence specificity similar to that of the Nielsen-type PNA a...

Spectral prediction models are widely used for characterizing classical, almost transparent ink halftones printed on a diffuse substrate. Metallic-ink prints however reflect a significant portion of light in the specular direction. Due to their opaque nature, multi-color metallic halftones require juxtaposed halftoning methods where halftone dots of different colors are laid out side-by-side. I...

TAYLOR, C. RICHARD, RAZI DMI'EL, MICHAEL FEDAK, AND KNUT SCHMIDT-NIELSEN. Energetic cost of running and heat balance in a large bird, the rhea. Am. J. Physiol. 221(Z): 597-601. 1971.-The energetic cost of running in the rhea (Rhea americana), determined as oxygen consumption, increased linearly with increasing speed. Oxygen consumption (M, ml 02 g-1 hr-I) relative to running velocity (v, km hr-...

We show that if an orientable Seifert fibered space M with an orientable genus g base space admits a strongly irreducible horizontal Heegaard splitting then there is a one-to-one correspondence between isotopy classes of strongly irreducible horizontal Heegaard splittings and elements of Z. The correspondence is determined by the slopes of intersection of each Heegaard splitting with a collecti...

TAYLOR, C. RICHARD, KNUT SCHMIDT-NIELSEN, AND JACOB L. RAAB, Scaling of energetic cost of running to body size in mammals. Am. J. Physiol. 219(4) : 1104-l 107. 1970.-The purpose of this study was to see if a convenient relationship could be found between the energetic cost of running and the body weight of mammals. We found that steady-state oxygen consumption of seven groups of mammals (21 g-1...

Each year during Experimental Biology (EB), an informal class reunion takes place at the President’s Reception that is traditionally documented by a group picture of the current, past, and elected presidents in attendance. Marty Frank, APS Executive Director, shared the most recent one a few days after EB. This year’s presidents’ picture – with a distinctive and impressive group of women front ...

In “zero-parameter” or classical Nielsen fixed point theory one studies Fix(f) := {x ∈ X | f(x) = x} where f : X → X is a map. In case X is an oriented compact manifold and f is transverse to the identity map, idX , Fix(f) is a finite set each of whose elements carries a natural sign, ±1, the index of that fixed point. The set Fix(f) is partitioned into Nielsen classes. Adding the indices withi...

In classical fixed point and coincidence theory, the notion of Nielsen numbers has proved to be extremely fruitful. Here we extend it to pairs ( f1, f2) of maps between manifolds of arbitrary dimensions. This leads to estimates of the minimum numbers MCC( f1, f2) (and MC( f1, f2), resp.) of path components (and of points, resp.) in the coincidence sets of those pairs of maps which are ( f1, f2)...
