Wave Phenomena in Physiological Flows

IMA Journal of Applied Mathematics, 1984
The aim of this paper is twofold: for a newcomer in the field of physiological fluid mechanics it offers a very short and clear presentation of the one-dimensional theory of pressure waves in elastic tubes (section 2). In this theory the main assumption is the relation between the channel (tube) cross-section area and internal pressure, the so called ...

A Physiological Model for Motion-Stereo Integration and a Unified Explanation of Pulfrich-like Phenomena

Vision Research, 1997
Many psychophysical and physiological experiments indicate that visual motion analysis and stereoscopic depth perception are processed together in the brain.

Modelling Complex Phenomena in Physiology

2020
Several important topics are introduced in this chapter. Cortical spreading depression (CSD) is a complex pathophysiological phenomenon. A relatively comprehensive review on its modelling is presented. The kidney regulation is also mentioned and shown with the computational model. Furthermore, the heart physiome and brain projects are outlined.

Physiological function and regulation of ascorbate peroxidase isoforms.

Journal of Experimental Botany
Ascorbate peroxidase (APX) reduces H2O2 to H2O by utilizing ascorbate as specific electron donor and constitutes the ascorbate-glutathione cycle in organelles of plants including chloroplasts, cytosol, mitochondria, and peroxisomes. It has been almost 40

Body Image Phenomena and Measures of Physiological Performance

Research Quarterly. American Association for Health, Physical Education and Recreation, 1968
Abstract This study was designed to investigate the relationships between three measures of body image and two measures of physiological performance. The Fisher-Cleveland Barrier Index, the Secord Homonym Test, and the Body Cathexis Questionnaire were correlated with dominant hand grip strength and the Michael-Gallon revision of the Harvard Step Test ...

Cellular Physiology of Epileptogenic Phenomena

1994
Epilepsy is one of the most frequently occurring nervous diseases. One out of 200 persons suffers from epilepsy. Nevertheless, there is still no definite radical therapy against epilepsy. Actual therapy against epilepsy is merely the expectation of a spontaneous cure by long-term inhibition of convulsions that facilitate the next convulsions using so ...

Raster-scan method for observing physiological entrainment phenomena

Medical & Biological Engineering & Computing, 1982
A simple raster-scan display, using a small interactive microcomputer with graphics capability, is described and gives visual indication of various entrainment-type phenomena. In particular, almostentrainment and transient behaviour are easily detectable.

Physiological Relevance of Scaling of Heart Phenomena

2002
Most methods used to analyze experimental data are based on the assumption that the data is from a Gaussian distribution and uncorrected. We describe methods to analyze data from scaling phenomena that do not have a Gaussian distribution [8.1–8.3] or involve long-range correlations [8.4–8.6]. We then show how those scaling methods have proved useful in

Relating Physiological, Physical, and Political Phenomena

International Political Science Review, 1987
We cannot easily avoid structuring our explanations of self and society as well as of in-groups and out-groups without recourse to the center-periphery archetype. The capital city of one's country is typically located in the center of Mercator maps, and subjects who locate the self at the center of a symbolic space give a more rapid interpretation of ...
