A quantitative performance evaluation of a robot teaching method using a force/moment direction sensor is presented. The performance of the teaching method using the force/moment direction sensor is compared with the conventional teaching pendant method. Two types of teaching tasks were designed and the teaching times required to complete the teaching tasks were measured and compared. Task A re...

Site-specific isopeptide linkages between the ε-amino group of a lysine residue in one protein and a carboxyl group in another are central to ubiquitin-mediated protein degradation and other cellular processes. These linkages are inaccessible with common recombinant DNA techniques. Here, we describe a method to link two proteins by an authentic isopeptide bond. The method unites three technique...

Synthesis of random biscoumarin copolyester bearing pendant 3-(trifluoromethyl)styrene was prepared by the reaction of biscoumarin monomer 3 and hydroquinone 5 with azeloyl chloride. The influence of pendant 3-(trifluoromethyl)styrene unit on the properties of copolyester such as inherent viscosity, solubility, and thermal stability was investigated and compared in detail. The inherent viscosit...

A novel electrochemical system has been developed for monitoring the cyclic AMP-dependent protein kinase (PKA) activity. In this method, PKA activity was monitored as the change in the redox current of a ferrocene-pendant PKA substrate peptide (Fe-LRRASLG) on a gold electrode, which had been modified with thioctic acid, using cyclic voltammetry. The phosphrylation of the ferrocene-pendant subst...

Multiple benefits of oxygen therapy for hypoxemic patients with chronic lung disease are well established. Steady flow oxygen therapy is inefficient, wasteful and has a high cost. The Oxymizer pendant improves efficiency of oxygen delivery compared with SF. However, the device requires that the patient inhale and exhale nasally to maximize its oxygen-saving properties. When patients do PLB they...

A (p, q) graph G is called edge-magic if there exists a bijective function f : V (G) ∪ E(G) → {1, 2, . . . , p + q} such that f(u) + f(v) + f(uv) is constant for any edge uv of G. Moreover, G is said to be super edgemagic if f(V (G)) = {1, 2, . . . , p}. Every super edge-magic (p, q) graph is harmonious, sequential and felicitous whenever it is a tree or satisfies q ≥ p. In this paper, we prove...

Nucleic acids contain severa' characteristic structural features: a chiral center adjacent to the base, a stereoregular, hydrophilic poly(phosphate-ribose) backbone which is negatively charged at neutral pH, and a helical secondary structure arising from conformational preferences enforced by base-stacking. We have prepared and studied several synthetic polynucleotide analogs having linear poly...
