چکیده
Based on research conducted by NCBI’s comparative genomics group, the database of Clusters of Orthologous Groups of proteins (COGs) represents a phylogenetic classification of proteins encoded in complete genomes. The COGs are derived from an “all-against-all” sequence comparison of the encoded proteins. Each COG consists of individual proteins or groups of paralogs from at least three lineages and is therefore considered to correspond to an ancient conserved domain. The database is designed to support research on genome evolution as well as functional annotation of genomes.

Severity of winter seasons in the northern Baltic Sea between 1529 and 1990: reconstruction and analysis
This paper presents the reconstructed severity of winter seasons in the northern Baltic Sea on the basis of historical time series of ice break-up at the port of Riga (1529–1990). The winter seasons are classified as mild, average severe. Results of statistical analysis of time series of the date of ice break-up arranged according to the severity of winter seasons are given. A decreasing trend ...
متن کاملCorrelation of Results on Winter-Summer Changes in Cholesterol-Part I
A question of interest is whether there is evidence of larger seasonal change for certain subgroups of subjects. One possibility is that there is a relationship between the amount of seasonal change and baseline values of other variables. We examined this possibility by constructing simple correlations between cholesterol (winter-summer) changes and average levels of other variables. For exampl...
متن کاملWinter emergency pressures for the NHS: contribution of respiratory disease, experience in North Staffordshire district.
The rise in emergency medical admissions in winter in the NHS hospitals in the United Kingdom has been recognized to reflect respiratory and cardiovascular illness. In our study we looked at the contribution of respiratory disease to the winter pressures in our district. Respiratory disease related emergency admissions increased twofold in the winter months, with obvious implications for worklo...
متن کاملEuclidean Pawel Winter 187 trees visibility
The notion of Steiner visibility graphs is introduced. Their applicability in connection with the construction of good quality suboptimal solutions to the Euclidean Steiner tree problem with obstacles is discussed. Polynomial algorithms generating Steiner visibility graphs are described.
متن کاملStratification and Double-Diffusive Convection in the Bab-el-Mandeb Strait during Winter Monsoon
Investigation of stratification in marine environments is always considered by researchers. In this study double-diffusive convection and stratification in the Bab el Mandeb strait is investigated by analyzing of field data. Measurement of seawater temperature and salinity from ARGO project (2009 to2014) and also R-V Knorr (2001) cruise with the daily average of seawater temperature and salinit...
متن کاملEffect of Typhula Phacorrhiza on Winter Injury in Field Trials across Canada
An isolate of the fungus Typhula phacorrhiza (Reich:Fr.) Fr. was evaluated in field tests across Canada for suppression of winter injury which was rated based on combined abiotic and biotic symptoms after snowmelt. This isolate, TP94671, has been identified in previous tests as being suppressive to gray snow mold, and a specific purpose of these trials was to evaluate the effect on pink snow mo...
