The rapid urbanization has exerted tremendous pressure on natural systems in mountains. As a measure of sustainable use of natural resources, ecological footprint is an important basis for judging whether the development of a country or region is within the biocapacity. Taking Dali Bai Autonomous Prefecture as an example, this study comprehensively analyzes the impact of human activities on mou...

MOTIVATION To investigate structure-function relationships, life sciences researchers usually retrieve and classify proteins with similar substructures into the same fold. A manually constructed database, SCOP, is believed to be highly accurate; however, it is labor intensive. Another known method, DALI, is also precise but computationally expensive. We have developed an efficient algorithm, na...

In this paper we present the communication architecture of the DALI Logic Programming Agent-Oriented language and we discuss its semantics. We have designed a meta-level where the user can specify, via the distinguished tell/told primitives, constraints on communication or even a new protocol. Moreover, the user can define meta-rules for filtering and/or understanding messages via applying onto...

DALI (D isp lay A lgo r i t hm Language I n t e r p r e t e r ) is a spec ia l -purpose programming language ex tens ion f o r the c r e a t i o n and c o n t r o l o f changing p i c t u r e s . DALI p i c t u res are composed of elements c a l l e d p i c t u r e modules. These are analogous to procedura l a c t i v a t i o n s or processes, and con ta in a r b i t r a r y even t -d r i ven p...

Summary: The F2CS server provides access to the software, F2CS2.00, that implements an automated prediction method of SCOP and CATH classifications of proteins, based on their FSSP Z-scores (Getz et al., 2002), Availability: Free, at http://www.weizmann.ac.il/physics/complex/compphys/f2cs/.

Protein structural alignment is an important problem in computational biology. In this paper, we present first successes on provably optimal pairwise alignment of protein inter-residue distance matrices, using the popular dali scoring function. We introduce the structural alignment problem formally, which enables us to express a variety of scoring functions used in previous work as special case...

In this paper we introduce a novel feature of the DALI language: a DALI agent is now able to activate child agents and to feed them either with a goal to be reached or a result to be obtained. Each child agent is independent and can communicate with its father or with other agents. When the child finally reaches the given goal, it notifies the father. At any point, the latter may possibly decid...

The objective of upcoming research in the field of geoprocessing is to evolve interoperability standards to develop flexible and scalable controlling and simulation services. In order to overcome the limitations of proprietary solutions, efforts have been made to support interoperability among simulation models and geo information systems (GIS). Existing standards in the domain of spatial infor...
