In this letter, we propose a novel approach using wireless sensor networks (WSNs) to enhance the safety and efficiency of four-way stop-sign-controlled (FWSC) intersections. The proposed algorithm provides right of way (RoW) and crash avoidance information by means of an intelligent WSN system. The system is composed of magnetic sensors, embedded in the center of a lane, with relay nodes and a ...

Objectives: The natural origin of medicinal plants does not guaranteed their safety, as there are no sufficient studies on the safety, efficacy and toxicity to support their beneficial claims. Hence, this study aimed at investigating the oral acute toxicity of Adansonia digitata L. fruit shell extract on mice. Methods: Maceration method was employed for the extraction of Adansonia digitata fru...

INTRODUCTION Modification of alarm limits is one approach to mitigating alarm fatigue. We aimed to create and validate heart rate (HR) and respiratory rate (RR) percentiles for hospitalized children, and analyze the safety of replacing current vital sign reference ranges with proposed data-driven, age-stratified 5th and 95th percentile values. METHODS In this retrospective cross-sectional stu...

Evidence from sign language strongly supports three positions: (1) language is a coherent system with universal properties; (2) sign languages diverge from spoken languages in some aspects of their structure; and (3) domain-external factors can be identified that account for some crucial aspects of language structure -- uniform and diverse -- in both modalities. Assuming that any of these posit...

OpenID, a standard for Web single sign-on, has been gaining popularity both with Identity Providers, Relying Parties, and users. This paper collects the security issues in OpenID found by others, occasionally extended by the authors, and presents them in a uniform way. It attempts to combine the shattered knowledge into a clear overview. The aim of this paper is to raise awareness about securit...
