Autoradiographic analysis of the primary retinal projections in the thornback guitarfish reveals both contralateral and ipsilateral projections to diencephalic, pretectal, and tegmental nuclei and the optic tectum. A total of 12 retino-recipient cell groups receive ipsilateral as well as contralateral inputs. To date, all studies using Fink-Heimer or autoradiographic methods in elasmobranch fis...

What role do surface features (e.g., color) play in the establishment and maintenance of episodic representations of objects (object files)? Mitroff and Alvarez (2007) showed that stimuli that were linked by a continuous spatiotemporal history yielded object-specific preview benefits--a standard index of object files-whereas stimuli linked only by shared surface features did not. Here, it is sh...

Implication for health policy/practice/research/medical education: Monitoring of quality of life after liver transplantation is a step toward patient centered care, but unfortunately a comprehensive and scientific instrument for this evaluation is not yet available. Background medical and mental condition of patients as well as social and economic support of the patients should be considered fo...

FOR MORE THAN A CENTURY a large body of evidence has accumulated in the physiological and pathophysiological literature to support the close relationship between the demand of oxygen by the tissues and the supply of oxygen by the cardiorespiratory system. When the demand for oxygen changes, how is its supply altered to match the increased demand and what are the signals by which the increased d...

For a finite poset P = (V,≤), let Bs(P ) consist of all triples (x, y, z) ∈ V 3 such that either x < y < z or z < y < x. Similarly, for every finite, simple, and undirected graph G = (V,E), let Bs(G) consist of all triples (x, y, z) ∈ V 3 such that y is an internal vertex on an induced path in G between x and z. The ternary relations Bs(P ) and Bs(G) are well-known examples of so-called strict ...

The diversity of ways in which parasites reduce the fitness of their hosts has been documented during the past decades, and clearly indicates that parasites can often be considered as direct agents of selection. In natural systems, however, the outcome of a host-parasite interaction might be strongly determined by other ecological factors. Parasites can be detrimental to host fitness in one env...

We investigate the problem of sequential piecewise linear regression from a competitive framework. For an arbitrary and unknown data length n, we first introduce a method to partition the regressor space. Particularly, we present a recursive method that divides the regressor space into O(n) disjoint regions (partitions) that can result in approximately 1.5 different piecewise linear models on t...
