Ecology and management of exotic and endemic Asian longhorned beetle Anoplophora glabripennis
(Wiley: 12 months, 2009)
1 The Asian longhorned beetle is native to China and Korea, and was found for the first time outside its native habitat in the U.S.A. in 1996, with subsequent detections being made in Canada and several European countries. 2 ...
Diversity of Bacillus anthracis strains in Georgia and of vaccine strains from the former Soviet Union
(American Society for Microbiology, 2006)
Despite the increased number of anthrax outbreaks in Georgia and the other Caucasian republics of the former Soviet Union, no data are available on the diversity of the Bacillus anthracis strains involved. There is also ...
Phelps’ Lemma, Danes’ Drop theorem and Ekeland’s principle in locally convex spaces
A generalization of Phelps' lemma to locally convex spaces is proven, applying its well-known Banach space version. We show the equivalence of this theorem, Ekeland's principle and Danes' drop theorem in locally convex ...
Effects of biological soil crusts on seed bank, germination and establishment of two annual plant species in the Tengger Desert (N China)
The presence of biological soil crusts can affect the germination and survival of vascular plants, but the reasons are not well investigated. We have conducted a field investigation and greenhouse experiments to test the ...

An ε-lagrange multiplier rule for a mathematical programming problem on Banach spaces
The aim of this paper is to extend the multiplier rule due to Clarke for a nondifferentiable mathematical programming problem on a Banach space to e-minimal (suboptimal) solutions of the problem. This seems to be useful ...
Rewriting queries with arbitrary aggregation functions using views
(Association for Computing Machinery (ACM), 2006)
The problem of rewriting aggregate queries using views is studied for conjunctive queries with arbitrary aggregation functions and built-in predicates. Two types of queries over views are introduced for rewriting aggregate ...
