![]() Malware is an increasingly prevalent cyberthreat for consumers, business, and government agencies. ![]() Researchers: James Hayes, Mark Panisko, Matthew Cooper, Warren Harper, Timothy Stewart, Charles Hubbard, Mike Ripplinger, Matthew Covert, James Ely, Paul Humble, Daniel Keller, and Anthony Day.Ī biological-based approach allows MLSTONES to recognize evolving, never before seen malware by detecting similarities in the basic building blocks of the code -something that conventional malicious software detectors cannot do effectively. The system's technology&a pairing of national laboratory expertise in nuclear detection science and technology with commercial engineering and manufacturing capabilities &could revolutionize the collection and detection of radioxenon in the field. Xenon International works by collecting, separating, purifying, and quantifying radioxenon isotopes to continuously monitor for radioxenon evidence from underground nuclear explosions. Xenon International, a fully-automated radioxenon monitoring system developed by PNNL and Teledyne Brown Engineering, drastically improves existing national and international radioxenon monitoring capabilities by doubling the sensitivity of today’s systems. ![]() The ability to accurately detect nuclear explosions is a key component of national security and international treaty monitoring. The Xenon International System is shown with the nitrogen generator and the Uninterruptable Power Supply. All rights reserved.Xenon International is a fully automated unattended system designed to collect, separate, purify, quantify, and perform nuclear counting on radioxenon isotopes, as well as transmit data using two-way communications. The RCT estimated by the OPT was the only milk coagulation property to show good agreement with the FRM-derived value, although this was not true for the data from late-coagulating samples.Ĭopyright © 2012 American Dairy Science Association. The relative influence of days in milk on k(20) and a(45) varied, as did the effect of parity on a(45) and that of the measuring unit of coagulation meter on k(20) and a(30). The correlations between k(20) and a(45), and milk yield varied among instruments, as did the correlations between k(20), a(30), and a(45) and milk composition, and the correlations between a(45) and pH. The between-instrument correlation coefficients were either moderate (0.48 for a(30)) or low (0.24 and 0.17 for k(20) and a(45), respectively) when the same traits were compared. The proportion of noncoagulating samples for which k(20) could be estimated differed between instruments, being less for the OPT. 33.66 mm for the OPT and the FRM, respectively). 5.36 min for the OPT and the FRM, respectively), as did the a(45) figures (41.49 vs. ![]() The average k(20) values varied greatly (8.16 vs. Milk coagulation properties measured using the OPT differed considerably from those obtained using the FRM. Extending the analysis by either instrument to 90 min permitted RCT and k(20) values to be obtained even for late-coagulating milk samples. The trial was performed in the same laboratory, by the same technician, and following the same procedures. Individual milk samples of 913 Brown Swiss cows from 63 herds located in Trento Province (Italy) were analyzed for rennet coagulation time (RCT, min), curd-firming time (k(20), min), and 2 measures of curd firmness (a(30) and a(45),mm) using the 2 instruments and under identical conditions. ![]() The aim of the present study was to compare milk coagulation properties measured through a traditional mechanical device, the Formagraph (FRM Foss Electric A/S, Hillerød, Denmark), and a near-infrared optical device, the Optigraph (OPT Ysebaert SA, Frépillon, France). ![]()
