One typically expects classifiers to demonstrate improved performance with increasing training set sizes or at least to obtain their best performance in case one has an infinite number of training samples at ones’s disposal. We demonstrate, however, that there are classification problems on which particular classifiers attain their optimum performance at a training set size which is finite. Whe...

Simulation of natural phenomena, such as the evaluation of temperature and air flow distribution inside a room, evaluation of material damage due to mechanical and chemical loads, are crucial in the daily life of engineers. This paper presents the Computational Phenomena Pattern, whose objective is to standardize through a computational abstraction the complex interaction of coupled natural phe...

The Void Phenomenon consists in the apparent discrepancy between the number of observed dwarf halos in cosmic voids and that expected from CDM simulations. We approach the problem considering the challenging prospects of detecting field dwarf systems with halo masses ≤ 10 M⊙, via their possible HI emission. A brief review of recent work is followed by preliminary results from the ALFALFA survey...

The hypothesis that plasma chylomicrons in persons who ingest a cholesterol-rich diet are atherogenic is evaluated. Evidence is presented that in humans, and experimental animals, chylomicron remnants as well as low-density lipoproteins are taken up by arterial cells. In persons who do not have familial hyperlipoproteinemia, atherogenesis may occur during the postprandial period. Research direc...

The pathogenesis of primary Raynaud's phenomenon remains an enigma. Most evidence favors a local abnormality in the digital arteries as opposed to an increased activity of the sympathetic nervous system. The local fault may involve the alpha 2-adrenergic receptors, which are most important in reflex sympathetic vasoconstriction. Cooling blood vessels increase the sensitivity of alpha 2-adrenerg...

The origin of the nonlocal nature of quantum mechanics is investigated in the context of Everett's formulation of quantum mechanics. EPR phenomenon can fully be explained without introducing any kind of decoherence.

The pathogenesis of Raynaud's phenomenon is not fully understood. However, the last 20 yr have witnessed enormous increases in our understanding of different mechanisms which, singly or in combination, may contribute. A key point is that Raynaud's phenomenon can be either primary (idiopathic) or secondary to a number of underlying conditions, and that the pathogenesis and pathophysiology vary b...

A ntipsychotic medications were introduced in the 1950s and proved to be invaluable in the amelioration of schizophrenic symptoms. These agents gained widespread acceptance in the treatment of psychoneurologic disorders, including schizophrenia, Tourette’s syndrome, effective disorders, and dementia. Antipsychotics are also called neuroleptics because of their ability to induce a variety of neu...

Because total coronary artery occlusion was found in the early hours of transmural myocardial infarction, most of our research interest and treatment strategies focus on epicardial coronary arteries.1 Little attention, however, is paid to the coronary microvasculature. When a coronary artery is occluded, detrimental changes occur in the cardiac capillaries and arterioles. After relief of the oc...

Nature appears in Merleau-Ponty’s early texts more as a context for a phenomenology of embodied existence than as a topic of interest in its own right.1 Since the philosopher became intensely interested in nature only from 1955 or 1956 on, one might think that an exploration of the earlier phenomenology of perception and behavior constitutes a digression from the later “new” ontology. Yet there...
