The Dynamic Response of a Photoreceptor
1970Publisher Summary This chapter examines the dynamic response of the eye of the horseshoe crab (Limulus). The digital computer played an equally important role in testing the mathematical models by simulating the responses of the eye. The chapter discusses the established mechanisms for the transduction of light intensity to spike rate representing an

Kinematic and dynamic responses of the scrum
Computer Methods in Biomechanics and Biomedical Engineering, 2013In a rugby game, the scrum allows to restart a game to restart after a minor infringement. It is an important sequence for physical and psychological domination of the opponent (Quarrie and Wilson ...

Telomere Dynamics in Response to Chemotherapy
Current Molecular Medicine, 2005The use of chemotherapy provides an essential arm in the treatment of a number of cancers. The biological feature common to all cancerous cells that sensitizes them to chemotherapeutic agents is their elevated division rate. Rapidly dividing cells, such as tumor cells, are more sensitive to chemotherapeutic agents that act to initiate pathways leading ...

Dynamic Characteristics of Transient Responses
The Journal of Biochemistry, 2005Transient responses of signaling molecules are seen in a wide variety of cellular processes that are mediated by distinct molecular mechanisms. Although transient responses might intuitively be thought to depend on the absolute concentration of growth factors or the intensity of stimulation, we here introduce that some transient responses are prompted ...

The response dynamics of preferential choice
Cognitive Psychology, 2013The ubiquity of psychological process models requires an increased degree of sophistication in the methods and metrics that we use to evaluate them. We contribute to this venture by capitalizing on recent work in cognitive science analyzing response dynamics, which shows that the bearing information processing dynamics have on intended action is also ...

Dynamic response of a composite shell
9th Structural Dynamics and Materials Conference, 1968An approximate analytic solution is obtained to the transient response of an infinitely long cylindrical shell surrounded by a viscoelastic medium. A uniform, axially symmetric pressure pulse is applied to the interior of the shell. Two cases are treated: 1) the shell is considered to be elastic, and 2) the shell is considered to be a composite ...

The temporal dynamics of the stress response
Neuroscience & Biobehavioral Reviews, 1997This paper summarises the available evidence that failure of defense mechanisms in (semi)-natural social groups of animals may lead to serious forms of stress pathology. Hence the study of social stress may provide animal models with a high face validity. However, most of the animal models of human stress-disorders have concentrated on the consequences

Viscoelastic dynamic arterial response
Computers in Biology and Medicine, 2017Arteries undergo large deformations under applied intraluminal pressure and may exhibit small hysteresis due to creep or relaxation process. The mechanical response of arteries depends, among others, on their topology along the arterial tree. Viscoelasticity of arterial tissues, which is the topic investigated in this study, is mainly a characteristic ...

The Stress Response-A Dynamic Overview
Hospital Practice, 1988It has long been appreciated that the adrenocortical response to stress is mediated via the central nervous system. The isolation of corticotropin releasing hormone in 1981 provided an important “missing link” to the CNS, but many puzzling questions remain.
