Information-Driven Gas Distribution Mapping for Autonomous Mobile Robots.

The ability to sense airborne pollutants with mobile robots provides a valuable asset for domains such as industrial safety and environmental monitoring. Oftentimes, this involves detecting how certain gases are spread out in the environment, commonly referred to as a gas distribution map, to subsequently take actions that depend on the collected information. Since the majority of gas transducers require physical contact with the analyte to sense it, the generation of such a map usually involves slow and laborious data collection from all key locations.

Pretreatment with Zinc Alleviates the Adverse Effects of Tetrahydrocannabinol on Cultured Mouse Sertoli Cells: Role of Anti-apoptotic and Antioxidant Activities.

Background: Global rise in cannabis abuse during reproductive years has placed a large number of men at risk for the adverse consequences of δ-9-tetrahydrocannabinol (THC), the primary active component of cannabis. It has been reported that THC affects male fertility and causes testicular cell dysfunction and apoptosis. This study aimed to investigate the possible protective role of zinc pretreatment against the toxic effects of THC in cultured mouse Sertoli cells and the underlying mechanism.

Association of Presenting Symptoms With Abnormal Laboratory Values for Vector-Borne Illness - Experience in an Urban Gastroenterology Practice.

Purpose: In the clinical setting, it is not common practice to consider a vector bite, such as from a tick or flea, to be a contributing factor to chronic digestive symptoms. This article investigates associations we have observed among symptomatic patients and positive blood tests for vector-borne illness (VBI).

Methods: Patients who visited an urban gastroenterology clinic over a 3-year period were retrospectively reviewed.

An increase in heart rate variability can be an index for end point of resuscitation in trauma patients.

Purpose: The measurement of heart rate variability (HRV) is a non-invasive method to analyze the balance of the autonomic nervous system. The aim of this study was to compare the changes of HRV and base deficit (BD) during the treatment of trauma patients.

Methods: Forty-three trauma patients with a low injury severity scores (ISS < 24) and negative base excess on admission were included in this study.

Design and Performance Evaluation of an Algorithm Based on Source Term Estimation for Odor Source Localization.

Finding sources of airborne chemicals with mobile sensing systems finds applications across safety, security, environmental monitoring, and medical domains. In this paper, we present an algorithm based on Source Term Estimation for odor source localization that is coupled with a navigation method based on partially observable Markov decision processes. We propose a novel strategy to balance exploration and exploitation in navigation.
