Automatic postural responses following rapid displacement of a light touch contact during standing.
Download2015-01-01
Misiaszek, John E.; Forero, Juan; Hiob, Elizabeth; Urbanczyk, Theresa
Responses elicited by the rapid displacement of a light touch contact surface were investigated during standing with the eyes closed. During quiet standing the touch surface was moved with an imperceptible slow (0.5 Hz), small (0.5 cm) oscillation to entrain the participant’s sway. Periodically,...

This paper presents a strategy for autonomous locomotion trajectory planning for high-level control of lower-limb exoskeletons by defining a novel set of adaptive central pattern generators (ACPGs) to facilitate safe and compliant interaction with the human. A time-varying bounded-gain adaptive...

Autoregulation of RNA helicase expression in response to temperature stress in Synechocystis spCC 6803
Download2012
Owttrim, George W., Chamot, Danuta, Rosana, Albert R. R.
RNA helicases are ubiquitous enzymes whose modification of RNA secondary structure is known to regulate RNA function. The pathways controlling RNA helicase expression, however, have not been well characterized. Expression of the cyanobacterial RNA helicase, crhR, is regulated in response to...

The mountain pine beetle, Dendroctonus ponderosae (Coleoptera: Curculionidae) is a major forest pest of pines in western North America. Beetles typically undergo a one-year life cycle with larval cold hardening in preparation for overwintering. Two-year life cycle beetles have been observed but...

Herein, an averaging theory for the solutions to Cauchy initial value problems of arbitrary order,ε-dependent parabolic partial differential equations is developed. Indeed, by directly developing bounds between the derivatives of the fundamental solution to such an equation and derivatives of the...

Avian Cognition: Examples of Sophisticated Capabilities in Space and Song

Neil McMillan, Allison H. Hahn, Marcia L. Spetch, Christopher B. Sturdy
Though birds have traditionally and colloquially been considered less cognitively complex than mammals, and especially primates, more recent research has consistently refuted these assumptions. We argue that the impressive abilities of birds to navigate and communicate require considerable...

Numerous studies have considered the flow of a rectilinear, high Reynolds number, Boussinesq gravity current through a two-layer stratified ambient, however, far less is known concerning the analogue axisymmetric problem. Whereas in both instances there is the possibility of a dynamic coupling...

The serine/threonine kinase B-Raf is the second most frequently occurring human oncogene after Ras. Mutations of B-Raf occur with the highest incidences in melanoma, and the most common mutant, V600E, renders B-Raf constitutively active. The sodium proton exchanger isoform 1 (NHE1) is a...
