An analysis of variation in response time of CPU scheduling algorithms as a function of load: a simulation

This thesis analyzes a group of cpu scheduling algorithms on the basis of the variation in response time that results from changes in the system load. The results of this study quantify the differential degradation of performance across job categories. The job categories include short-burst interactive jobs as well as cpu intensive jobs. For each job type, measurements were made of average job turn-around time, weighted average turn-around time, and worst case response time. Additional statistics gathered include: ready-to-run queue size, cpu utilization and throughput. The three cpu scheduling algorithms compared are round-robin, shortest-job-first, and a multi-queue priority scheduler. The analysis utilizes a model encoded in ‘C’ which simulates an interactive time-sharing user community. The model allows scheduling algorithms to be measured with a controlled workload. The workload is varied by selecting the number of simulated users who are sharing the cpu

Complete Genome Sequences of Four Novel Human Coronavirus OC43 Isolates Associated with Severe Acute Respiratory Infection.

We report here the complete genome sequences of four human coronavirus (HCoV) OC43 isolates generated using targeted viral nucleic acid capture and next-generation sequencing; the isolates were collected in New Mexico and Arkansas, USA, in February (HCoV-OC43/USA/TCNP_0070/2016) and March (HCoV-OC43/USA/ACRI_0052/2016) 2016 and January 2017 (HCoV-OC43/USA/TCNP_00204/2017 and HCoV-OC43/USA/TCNP_00212/2017)

The Emergence of Zoonotic Onchocerca lupi Infection in the United States--A Case-Series.

This case-series describes the 6 human infections with Onchocerca lupi, a parasite known to infect cats and dogs, that have been identified in the United States since 2013. Unlike cases reported outside the country, the American patients have not had subconjunctival nodules but have manifested more invasive disease (eg, spinal, orbital, and subdermal nodules). Diagnosis remains challenging in the absence of a serologic test. Treatment should be guided by what is done for Onchocerca volvulus as there are no data for O. lupi. Available evidence suggests that there may be transmission in southwestern United States, but the risk of transmission to humans is not known. Research is needed to better define the burden of disease in the United States and develop appropriately-targeted prevention strategies
