Tape springs are being used with increasing frequency in today’s space industry to deploy small satellite aerials and array areas. However, to accurately model the deployment of an appendage mounted with tape spring hinges, it is necessary to accurately model the opening moments produced from the material strains in the tape spring fold. These moments are primarily a function of curvature. This...

OBJECTIVE To pilot informed consent materials developed for Aboriginal parents in a vaccine trial, and evaluate their design and the informed consent process. METHODS Cross sectional quantitative and qualitative survey of 20 Aboriginal and 20 non-Aboriginal women in Alice Springs. Information about the proposed research was presented to Aboriginal participants by an Aboriginal researcher, usi...

A navigation method for a lunar rover based on large scale wireless sensornetworks is proposed. To obtain high navigation accuracy and large exploration area, highnode localization accuracy and large network scale are required. However, thecomputational and communication complexity and time consumption are greatly increasedwith the increase of the network scales. A localization algorithm based ...

In this work we consider the following question: given a mechanical microswimming mechanism, does increased deformability of the swimmer body hinder or promote the motility of the swimmer? To answer this we run immersed-boundary-lattice-Boltzmann simulations of a microswimmer composed of deformable beads connected with springs. We find that the same deformations in the beads can result in diffe...

Titin, the largest protein in the human body, is well known as a molecular spring in muscle cells and scaffold protein aiding myofibrillar assembly. However, recent evidence has established another important role for titin: that of a regulatory node integrating, and perhaps coordinating, diverse signaling pathways, particularly in cardiomyocytes. We review key findings within this emerging fiel...

of ours, there immediately springs up a mushroom crop of theorists, who would account, each after his own fashion, for the phenomenon. First come the supernaturalists, who assign the event to the wrath of some offended God or Gods, on account of sins, real or imagined. The " sins of outrulers" is the most favorite formula in India. Next come the transcendentalist s, who attribute the circumstan...

Elastic network models have been used to study the properties of coarse grained models of proteins and larger biomolecular complexes. In this comment, we point out that it is important to build rotational symmetry, as well as translational symmetry, into these models that are designed to describe the rigidity, and the associated low-frequency deformations. This leads to strong restrictions on w...

In a previous paper* Fr. Sierp and myself have dealt with some of the numerous hot springs in the Bombay Presidency. The favourable reception which that paper has received relieves me of the necessity of dwelling once more on the importance of the subject. The methods used in the present paper in measuring the radio-activity of the water and the gases are the same as in the former investigation...

The goal of this paper is to address three key questions. First, what are residual stresses? Second, what causes them? And third, are they good or bad in terms of performance of springs? The first question will be addressed by beginning with some rudimentary definitions and discussion. The second will be addressed with a process-by-process evaluation of spring manufacturing. Each process will b...

We study the linear and nonlinear elastic behavior of amorphous systems using a two-dimensional random network of harmonic springs as a model system. A natural characterization of these systems arises in terms of the network coordination (average number of springs per node) relative to that of a marginally rigid network deltaz: a floppy network has deltaz<0, while a stiff network has deltaz>0. ...
