This issue of Animal Health Research Reviews contains the Proceedings of the Bovine Respiratory Disease Symposium 2014: ‘New Approaches to Bovine Respiratory Disease Prevention, Management and Diagnosis’, which was held on July 30 and 31, 2014 in Denver, Colorado, USA. Bovine respiratory disease (BRD) remains a leading cause of illness, death and decreased productivity for cattle in North Ameri...

The therapeutic efficacy of an early treatment protocol with an infection-stage adjusted fluoroquinolone regimen was evaluated in a field study on young bulls (YBs) presenting signs of bovine respiratory disease (BRD). A total of 195 YB (Charolais, Limousin, and Rouge-des-Prés breeds) from 6 farms implementing or not prophylactic antimicrobial treatments (PROPHY or absence) were randomly assign...

A study was conducted to evaluate the diagnostic and prognostic value of thoracic ultrasonography (TUS) in feedlot calves with clinical signs attributable to bovine respiratory disease (BRD). Twenty-nine BRD cases and 15 asymptomatic controls were evaluated using systematic TUS on the day of initial pull (day 0), and days 3, 6, 9, and 15. Four-second ultrasound loops were saved at 46 locations ...

We describe the diagnosis and treatment of bottlenecks in computer systems using decison theoretic techniques. The techniques rely on a high-level functional model of the interaction between application workloads, the operating system (Windows NT), and system hardware. Given a workload description, the model predicts the values of system counters observable with the Windows NT performance monit...

This paper describes an action research study which focussed on requirements capture for a subscription-based business-to-consumer (B2C) electronic commerce (EC) system. The study used a recently developed approach to requirements elicitation, the Business Rules Diagram (BRD) Method. The BRD method was adapted somewhat during the study and was found to be helpful in addressing difficulties of r...

The objective of this study was to characterize genetic and environmental factors influencing bovine respiratory disease (BRD) in beef cattle. Records from nine purebred and three composite breeds and a variety of F1 and three-way crosses, including the progeny of 12 additional different sire breeds produced over a 20-yr period (1983 to 2002), were evaluated for breed and heterozygosity effects...

Bovine respiratory disease (BRD) is the primary cause of morbidity and mortality in cattle during the feeding period. Management of BRD cases relies on the observation of cattle behavioral changes by caregivers. This paper describes the use of multiple antemortem diagnostic technologies in combination to improve outcomes in the clinical management of BRD.

Methods to improve accuracy of preclinical detection of bovine respiratory disease (BRD) are needed to reduce the economic impact of this disease, improve animal welfare, and promote more judicious use of antimicrobials in beef cattle. The objectives of this study were to retrospectively characterize time-series deviations in DMI and feeding behavior patterns preceding the display of observed c...

In a hardware transactional memory system with lazy versioning and lazy conflict detection, the process of transaction commit can emerge as a bottleneck. For a large-scale distributed memory system, we propose novel algorithms to implement commit that are deadlockand livelock-free and do not employ any centralized resource. These algorithms improve upon the state-of-the-art by yielding up to 59...
