Evolution of dim-light and color vision pigments.
A striking level of diversity of visual systems in different species reflects their adaptive responses to various light environments. To study the adaptive evolution of visual systems, we need to understand how visual pigments, the light-sensitive molecules, have tuned their wavelengths of light absorption. The molecular basis of spectral tuning in visual pigments, a central unsolved problem in...
متن کاملLong-term evolution of dim isolated neutron stars
The X-ray dim isolated neutron stars (XDINs) have periods in the same range as the anomalous X-ray pulsars (AXPs) and the soft gamma-ray repeaters (SGRs). We apply the fallback disc model, which explains the period clustering and other properties of AXP/SGRs, to the six XDINswithmeasured periods and period derivatives. Present properties ofXDINs are obtained in evolutionary scenarios with surfa...
متن کاملGRADI: A Graphical Database Interface for a Multimedia DBMS
In this paper we describe the GRAphical Database Interface (GRADI) of a Multimedia Database Management System. As generally true, the user interface is an important part of the system which strongly determines the effectiveness of using it. In order to find an easy and natural way of interacting with the MDBMS system we examined the query specification process used by humans. We found that incr...
متن کاملU-DBMS: A Database System for Managing Constantly-Evolving Data
In many systems, sensors are used to acquire information from external environments such as temperature, pressure and locations. Due to continuous changes in these values, and limited resources (e.g., network bandwidth and battery power), it is often infeasible for the database to store the exact values at all times. Queries that uses these old values can produce invalid results. In order to ma...
متن کاملA new approach for database “Column-oriented DBMS”
As we all know that many different kind of organization need database for required information from different area like analytic, different types of reports and other many reasons. As the organization grows the database also grow into millions of records spared over many tables and business intelligent/science. And if any organization want any specific report strategic analysis, and other busin...
