The title compound, [Zn(C(12)H(11)N(2)O(4))Cl](n), contains a centrosymmetric dimetal tetra-carboxyl-ate paddle-wheel moiety in which the Zn(II) atom is square-pyramidally coordinated by four carboxyl-ate O atoms at the basal positions and one Cl(-) anion at the apical position. Each paddle-wheel unit is joined to four such neighbours through bridging dicarboxyl-ate ligands, producing a two-dim...

the date of any previous instruction on defibrillation technique were also recorded. Data were collected from 20 consultants, 2 staff grades, 38 registrars, 31 senior house officers, and 10 preregistration house officers. There was no significant difference (determined by analysis of variance) in paddle positioning between different grades or specialties or between those who had received defibr...

An approach for the correction of cryptotia using a superiorly based superficial mastoid fascial flap and a skin paddle is introduced. The buried portion of the auricle was exposed through an incision made along the upper part of the helix, followed by an appropriate correction of the deformed cartilage. Protrusion of the upper portion of the auricle was accomplished using anchoring sutures. A ...

Atenolol is a widely used drug for treating heart conditions available worldwide under various trade names by several generic pharmaceutical manufacturers. The purpose of this study was to evaluate and compare the dissolution performance of several commercially available generic atenolol tablets using both basket and paddle methods described in the United States Pharmacopeia-National Formulary ...

The Lon AAA+ protease (LonA) is an evolutionarily conserved protease that couples the ATPase cycle into motion to drive substrate translocation and degradation. A hallmark feature shared by AAA+ proteases is the stimulation of ATPase activity by substrates. Here we report the structure of LonA bound to three ADPs, revealing the first AAA+ protease assembly where the six protomers are arranged a...

BACKGROUND Traditionally, reconstruction of concurrent maxillary and mandibular defects on opposite sides of the facial skeleton often requires use of 2 free osseocutaneous flaps. A new technique of using a differentially split osteomyocutaneous peroneal artery-based combined (OPAC) flap for 1-stage reconstruction of left maxillary and right mandibular defects is presented. METHODS An OPAC fl...

This paper presents an optimal trajectory planner for a robotic batting task . The specific case of a table tennis game performed by a robot is considered. Given an estimation of the trajectory of the ball during the free flight, the method addresses the determination of the paddle configuration (pose and velocity) to return the ball at a desired position with a desired spin. The implemented al...

Members of the XMAP215/Dis1 family of microtubule-associated proteins (MAPs) are essential for microtubule growth. MAPs in this family contain several 250 residue repeats, called TOG domains, which are thought to bind tubulin dimers and promote microtubule polymerization. We have determined the crystal structure of a single TOG domain from the Caenorhabditis elegans homolog, Zyg9, to 1.9 A reso...

The self-assembly of copper(II) ions and 5-(2-hydroxyethoxy)benzene-1,3-dicarboxylate (1) leads to Nanoballs in which twelve dinuclear copper(II) paddle-wheel units are interconnected via 24 ligands. The structure of the spherical coordination compound decorated with 24 hydroxy groups has been determined by single crystal X-ray structure analysis. As a model for the integration of Nanoballs int...

Recently, considerable research efforts have been devoted to the design of methods to learn from data overcomplete dictionaries for sparse coding. However, learned dictionaries require the solution of an optimization problem for coding new data. In order to overcome this drawback, we propose an algorithm aimed at learning both a dictionary and its dual: a linear mapping directly performing the ...
