Apparent movement is used to examine the nature of the visual information which specifies object identity. Constructive feature-comparison theories rely on static formal information and predict that two phases of an apparent movement display must be featurally similar in order to appear as a single object in motion. An opposing Gibsonian model is based on abstract geometrical information and pr...

OBJECTIVES To characterize plasmids encoding extended-spectrum β-lactamases (ESBLs) from a recent UK collection of clinical Escherichia coli isolates. METHODS The isolates comprised 118 ESBL producers referred from 54 laboratories. Plasmids were transferred by electroporation, and their incompatibility groups, associated addiction systems and resistance genes with the flanking genetic environ...

To date, numerous inorganic nanocarriers have been explored for drug delivery systems (DDSs). However, the clinical application of inorganic formulations has often been hindered by their toxicity and failure to biodegrade. We describe here a transformable liquid-metal nanomedicine, based on a core-shell nanosphere composed of a liquid-phase eutectic gallium-indium core and a thiolated polymeric...

We have identified a highly transformable strain of Actinobacillus pleuropneumoniae whose competence is regulated by the competence-activator Sxy as in other Pasteurellaceae. Other strains were poorly transformable or nontransformable. The genomes of two poorly transformable strains contain intact sets of competence genes. Moreover, we show that the low competence of one of these strains is not...

Transformable products (or transformers), those with two or more functional states, are increasingly utilized by our society. As the mobility and complexity of life increases, so must the adaptability of the products which we use. To develop more adaptable products and systems, we need new design techniques. Transformer design methodology is a discipline with opportunity for expansive developme...

In this paper, we present the design and implementation of the wireless camera component, communications, and control components for a gun-launched, transformable Unmanned Aerial Vehicle (UAV). The transformable UAV is designed to be able to detect standard targets. In addition, the transformable UAV can be converted from a gun-launched projectile transformed to a UAV, and bevisually guided to ...
