Here we show that S. suis, a major bacterial pathogen of pigs and emerging pathogen in humans responds to a peptide pheromone by developing competence for DNA transformation. This species does not fall within any of the phylogenetic clusters of streptococci previously shown to regulate competence via peptide pheromones suggesting that more species of streptococci may be naturally competent. Ind...

The presence of numerous complex organic molecules (COMs; defined as those containing six or more atoms) around protostars shows that star formation is accompanied by an increase of molecular complexity. These COMs may be part of the material from which planetesimals and, ultimately, planets formed. Comets represent some of the oldest and most primitive material in the solar system, including i...

Geostationary Ocean Colour Imager (GOCI) is the first Ocean Colour Imager to operate from a Geostationary Orbit. It was developed by Astrium SAS under KARI contract in about 3 years between mid 2005 and October 2008 and integrated on-board COMS satellite end 2008 aside the COMS Meteo Imager (MI). COMS satellite was launched in June 2010 and the in-orbit commissioning tests were completed in beg...

CO2 capture is essential for reducing the carbon footprint of coal-fired power plants. Here we show, both experimentally and computationally, a new design strategy for capturing CO2 in nanoporous adsorbents. The approach involves 'complementary organic motifs' (COMs), which have a precise alignment of charge densities that is complementary to the CO2 quadrupole. Two promising COMs were post-syn...

To facilitate the study of pneumococcal genes that are essential for viability or normal cell growth, we sought to develop a tightly regulated, titratable gene depletion system that interferes minimally with normal cellular functions. A possible candidate for such a system is the recently discovered signal transduction pathway regulating competence for natural transformation in Streptococcus th...

Facial Recognition remains one of the most popular fields in computer imaging research due to its broad scope of applications in identity verification, human computer interactions, law enforcement applications and video surveillance systems. Although numerous artificial intelligence and machine learning techniques have been successfully applied to still image recognitions, recognition in video ...

CONTEXT Counterstrain is 1 osteopathic manipulative treatment technique taught to osteopathic medical students, but teaching all 300 counterstrain tender points is not feasible at most colleges of osteopathic medicine (COMs) because of time limitations. OBJECTIVE To identify high-yield tender points in osteopathic medical students for teaching and to assess for correlations between tender poi...

The R&D in satellite communications in Korea has been driven mainly by KCC (Korea Communications Commission) but in a small scale compared to Korea space development program organized by MEST (Ministry of Education, Science and Technology). Public and civilian satcom sector R&D has been led mainly by ETRI with small/medium companies contrary to rare investment in private sector while military s...

In this study, we examine the phenomenon of the decline in valuation of dot-com organizations and propose that dot-com organizations that have continuously altered their business model in response to the environment have been rewarded by superior valuations in the market place. We first present the dominant perspectives in organizational adaptation research, and discuss their relevance to the c...
