Towards physiological motion compensation for flexible needle interventions
2015 IEEE/RSJ International Conference on Intelligent Robots and Systems (IROS), 2015Flexible bevel-tipped needle steering has been an active research topic since the last decade. However, most of the work presented so far performs flexible needle steering in static phantoms or non-static virtual environments. The insertion of flexible bevel-tipped needles into soft-tissue subjected to motion disturbances is still an open research ...

Distortion Compensating, Condenser-Earphone Driver for Physiological Studies
The Journal of the Acoustical Society of America, 1968A design for a condenser earphone driver is given. The driver predistorts electrical input signals to counteract the inherent square-law operation of the condenser earphone. Thus, smaller-diameter earphones, with their wider bandwidth characteristics, can be used at stimulus levels of interest without appreciable harmonic distortion.

Pesticide Biochemistry and Physiology
The Drosophila melanogaster MD-RR strain contains an Rdl mutation (A301S) resulting in resistance to several insecticide classes viz. phenyl pyrazoles (e.g., fipronil), cyclodienes (e.g., dieldrin), and chlorinated aliphatic hydrocarbons (e.g., lindane).

IEEE Transactions on Instrumentation and Measurement, 2022
Remote photoplethysmography (rPPG) measurement has received much attention due to its attractive applications in contactless physiological monitoring. It calculates the blood volume pulse from color signals with a normal camera.

Vestibular Compensation:Physiological und Clinical Aspects
Acta Oto-Laryngologica, 1983Vestibular compensation is achieved by means of a multisensory substitution process. Experimental and clinical observations indicate that patients, suffering from a sudden loss of vestibular function, should get an early multisensory training in order to induce adaptive changes as soon as possible.

Neurocomputing, 2001
Abstract In a typical neurophysiological recording, the shape of the voltage trace due to an action potential depends, among other things, on the mutual geometry of the tissue and the electrode, and on the overall health of the preparation. These parameters change throughout the duration of the experiment, typically continuously and slowly, with ...

Theory, simulation, and compensation of physiological motion artifacts in functional MRI
Proceedings of 1st International Conference on Image Processing, 2002Mapping the location of brain activity is a new and exciting application of magnetic resonance imaging (MRI). This application area has already seen the use of a variety of magnetic resonance image acquisition methods, including spin-warp, spiral k-space, and echo-planar imaging, each of which has its own advantages and disadvantages.

Intrauterine asphyxia and the breakdown of physiologic circulatory compensation in fetal sheep
American Journal of Obstetrics and Gynecology, 1990In response to acute hypoxemia, the fetus invokes physiologic compensatory mechanisms that cause a preferential redistribution of the circulation to sustain the brain, heart, and adrenal gland and maintain blood flow to the placenta. These mechanisms are available for a limited time and eventually the fetus is no longer able to maintain preferential ...
