DNA transformation is a widespread process allowing bacteria to capture free DNA by using filamentous nano-machines composed of type IV pilins. These proteins can act as DNA receptors as demonstrated by the finding that Neisseria meningitidis ComP minor pilin has intrinsic DNA-binding ability. ComP binds DNA better when it contains the DNA-uptake sequence (DUS) motif abundant in this species ge...

In relation to injecting drug use, many European and U.S. efforts to prevent new HIV infections focus on sexual and injecting risk behavior of persons who are not infected (both injectors and sexual partners of injectors). Behavioral changes among these HIVnegatives are given that knowledge and means are present dependent on a desire for self-protection against HIV infection. However, in order ...

This paper considers a resource allocation problem in device-to-device (D2D) communications sharing the same frequency spectrum. In particular, cellular users (CUs) utilize non-orthogonal multiple access (NOMA) while D2D (DUs) adopt orthogonal division (OFDMA). A multi-objective optimization (MOOP) is formulated, which jointly maximizes sum rate of DUs and CUs uplink taking into account maximum...

Over 10,000 Hybrid Tea rose varieties have been described. The large number of varieties and the size of the reference collections may cause problems in DUS (Distinctiveness, Uniformity, and Stability) testing. Molecular markers may help to solve these problems by providing high power to identify and recognise seedlingderived varieties based on unique genotypes, while grouping mutants into grou...
