A session type is an abstraction of a sequence of heterogeneous values sent over one communication channel. Session types can be used for specifying stream-based Internet protocols. We consider session types in a setting with asynchronous communication over buffered channels. Due to buffering, a process may write ahead before the reading process picks up the data. Thus the types of the two ends...

Extensive work has been carried out by the U.S. Department of Energy (DOE) in the development of a proposed geologic repository at Yucca Mountain (YM), Nevada, for the disposal of high-level radioactive waste. In support of this development and an associated license application to the U.S. Nuclear Regulatory Commission (NRC), the DOE completed an extensive performance assessment (PA) for the pr...

Background: Ensuring food safety and minimizing risks require coordinated efforts of various institutions. The objective of this study was to determine how Ghanaian consumers score the competence of public institutions in controlling food safety risks and the effects of this perceived score on their level of concerns about food safety risks. Methods: Totally, semi-structured questionnaire admi...

Program certification techniques formally show that programs satisfy certain safety policies. They rely on the correctness of the safety policy which has to be established externally. In this paper we investigate an approach to show the correctness of safety policies which are formulated as a set of Hoare-style inference rules on the source code level. We develop a framework which is generic wi...

Reports suggesting that gram doses of ascorbic acid are beneficial for the prevention and treatment of several disorders have led to widespread ingestion of vitamin C supplements. Possible adverse health effects of this practice have, therefore, received considerable scrutiny. Of major concern has been the influence of ingesting gram amounts of ascorbic acid on renal calcium oxalate stones, sys...

Patient Safety (PS) standardization is the key to improve interoperability and expand international share of incident reporting system knowledge. By aligning the Patient Safety Categorial Structure (PS-CAST) to the Basic Formal Ontology version 2 (BFO2) upper level ontology, we aim to provide more rigor on the underlying organization on the one hand, and to share instances of concepts of catego...

Architects use a variety of techniques to evaluate designs for the desired levels of specific quality attributes. Reasoning frameworks are used to guide architecture definition by determining the extent to which a software architecture satisfies its quality requirements. There is much work on reasoning about quality attributes such as performance and modifiability but there has been little work...

SLAyer is a program analysis tool designed to automatically prove memory safety of industrial systems code. In this paper we describe SLAyer’s implementation, and its application to Windows device drivers. This paper accompanies the first release of SLAyer.
