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 ...

The species Campylobacter jejuni is considered naturally competent for DNA uptake and displays strong genetic diversity. Nevertheless, nonnaturally transformable strains and several relatively stable clonal lineages exist. In the present study, the molecular mechanism responsible for the nonnatural transformability of a subset of C. jejuni strains was investigated. Comparative genome hybridizat...

Mechanical metamaterials are engineered materials whose structures give them novel mechanical properties, including negative Poisson's ratios, negative compressibilities and phononic bandgaps. Of particular interest are systems near the point of mechanical instability, which recently have been shown to distribute force and motion in robust ways determined by a nontrivial topological state. Here...

Transformable Robot In article number 2200051, Hong Suk Kang, Dong-Gyun Kim, Jong-Chan Lee, and co-workers present photo-controllable liquid crystalline networks (pc-LCNs) comprising static dynamic covalent dual-cross-links. The tailored network architecture of pc-LCNs enable UV-controllable reversible assembly/disassembly shape reconfiguration capabilities, while maintaining visible light-resp...
