Resources, Confusions, and Compatibility in Dual Axis Tracking: Displays, Controls, and Dynamics
… were integrated or separated, whether axis controls were integrated into one stick or remained separate, and whether the control dynamics on the two axes were the same or different. Tracking error increased and control activity decreased as a function of the summed difficulty of the two …

Progesterone Regulation of Insulin like-Growth Factor : Binding Protein-5 Gene Transcription in Human Osteoblasts
… increased IGF)3P-5 gene transcription to 400% of control. To define the underlying mechanisms, the human IGF13P-5 gene proximal promoter was cloned and sequenced. The proximal 500 bp of this region contains TATA and CAAT boxes, five putative PG response element (PRE) half-sites and two tandem …

Performance Analysis Of Non-Linear Adaptive Control Laws Using Hardware in the Loop of an Unmanned Aerial System
… performance.</p> <p>In this thesis, different control laws based on the formation flight geometry problem, nonlinear dynamic inversion and an artificial immune system adaptive mechanism , are implemented in hardware-in-the-loop as a precursor for in-flight testing. These controllers are …

A model for end-to-end delay in distributed computer systems
… be a remote database update or a real-time control activity. To model end-to-end performance, one must include the host computers, the network interface units (NIUs), the host-NIU links, and the NIU-NIU links. Based on Jackson's Theorem, total delay for single-thread transaction traversing a …

The use of multi-sensory stimulation to improve functional performance in older people with dementia: a randomised single blind trial
… care (Baker et al, 1997). Despite this, no controlled studies have been conducted to explore the efficacy of this intervention on functional performance. This study explores to what extent, if any, MSEs influence function, mood and behaviour of people with moderate / severe dementia compared …

The Impact of Prefrontal Cortex "Warm Up" on Immediate Cognitive Reappraisal Ability in Older Adolescents with Elevated Symptoms of Depression
… who were randomly assigned to a lab-based WM or control activity followed by a CR task. Overall, results failed to support the effectiveness of “warm up” to augment CR performance. However, current level of depression predicted negative bias and sadness ratings after CR instructions, and this …

Using Small Molecule Tools to Study ATPase Mechanoenzymes
… ASPIRe-1 (Allele-Specific, Proximity-Induced Reactivity-based inhibitor-1), a cell-permeable compound that selectively inhibits katanin with an engineered cysteine mutation. Only in cells expressing mutant katanin, ASPIRe-1 treatment increases the accumulation of CAMSAP2 at microtubule …

Display Size Contamination of Attentional and Spatial Tasks: An Evaluation of Display Minification and Axis Compression
… exhibited higher tracking error and lowered control activity when display size was reduced, and this effect was amplified for axis compression. The effect resulted both from the lowered resolution of the smaller display, which provided less information about small deviations than its larger …

A structured approach to production control in integrated manufacturing systems
The planning and control of manufacturing systems is a complex activity involving a myriad of decisions and optimization algorithms. ln a Computer Integrated Manufacturing System (CIMS) these decisions and algorithms span several functions, require information from several sources, and have …
