Active containment systems based on the controlled expression of a lethal gene are designed to increase containment of recombinant micro-organisms used for environmental applications. A major drawback in containment is the existence of mutations that generate surviving cells that cease to respond to the toxic effect of the lethal function. In this work the authors have developed for the first t...

This paper is a transcription of the texts read by three commentators appointed scientific committee to open first debate session convened in June 2020 as continuation virtual QSN conference held month before. It should be noted that, for practical reasons well time constraints (there were researchers from countries with different zones), comments did not address presentations order which they ...

We study containment of conjunctive queries that are evaluated over databases that may contain tuples with null values. We assume the semantics of SQL for single block queries with a SELECT DISTINCT clause. This problem (“null containment” for short) is different from containment over databases without null values and sometimes more dif-

Since 1977, cost containment has been an integral part of health policy in the Federal Republic of Germany. The common goal of the cost-containment acts was to bring the growth of health care expenditures in line with growth of wages and salaries of sickness fund members. The Health Care Reform Act of 1989 is the most recent manifestation of this policy. The main features of the numerous cost-c...

Our goal is to study type containment, some variations on the type-containment relation, and how it can be extended to other programming language features such as products, side effects, existential types. We will study some language meta-theoretical properties. Notre but est d’étudier le type containment, quelques variantes sur la relation de type containment, et comment elle peut être étendue...

Although containment is frequently advocated as a fall-back option for eradication, analysis shows that it is not necessarily more economic or effective. While containment has one major advantage over eradication, in that a smaller area is managed, this must be balanced against its disadvantage; that it must continue indefinitely. Moreover, both containment and eradication programs are at risk ...

Antimicrobial drug resistance (AMR) is widely recognized as a global public health threat because it endangers the effectiveness of treatment of infectious diseases. In 2001 WHO issued the Global Strategy for Containment of Antimicrobial Resistance, but it has proved difficult to translate the recommendations of the Global Strategy into effective public health actions. The purpose of the Antimi...
