Abstract: We address the problem of predicting whether a driver facing the yellow-light-dilemma will cross the intersection with the red light. Based on driving simulator data, we propose a stochastic hybrid system model for driver behavior. Using this model combined with Gaussian process estimation and Monte Carlo simulations, we obtain an upper bound for the probability of crossing with the red light. This upper bound has a prescribed confidence level and can be calculated quickly on-line in a recursive fashion as more data become available. Calculating also a lower bound we can show that the upper bound is on average less than 3% higher than the true probability. Moreover, tests on driving simulator data show that 99% of the actual red light violations, are predicted to cross on red with probability greater than 0.95 while less than 5% of the compliant trajectories are predicted to have an equally high probability of crossing. Determining the probability of crossing with the red light will be important for the development of warning systems that prevent red light violations.

Education communities have significant food safety responsibilities. Risk gets pushed around global food service counterparties; a drama in itself and one that requires coverage in a separate blog post.*
Since 2013 we have been following the development of food safety standards; among them ANSI/NSF 2: Food Equipment one of a constellation of NSF food safety titles whose provisions cover bakery, cafeteria, kitchen, and pantry units and other food handling and processing equipment such as tables and components, counters, hoods, shelves, and sinks. The purpose of this Standard is to establish minimum food protection and sanitation requirements for the materials, design, fabrication, construction, and performance of food handling and processing equipment.
It is a relatively stable standard; developed to support conformance revenue for products. A new landing page seems to have emerged in recent months:
Manufacturers are required to meet the NEC and CEC electrical codes to have their food equipment sold and used in the United States and Canada. Watch our video for more details. pic.twitter.com/d0vUf4zUl2
Not trivial agendas with concepts that cut across several disciplines involving product manufacture, installation, operation and maintenance. We find a very strong influence of organizations such as Aramark and Sodexo. More on that in a separate post.
This committee – along with several other joint committees –meets frequently online. If you wish to participate, and receive access to documents that explain the scope and scale of NSF food safety standards, please contact Allan Rose, (734) 827-3817, arose@nsf.org. NSF International welcomes guests/observers to nearly all of its standards-setting technical committees. We expect another online meeting hosted by this committee any day now.
Keep in mind that all NSF International titles are on the standing agenda of our Nourriture (Food) colloquia; open to everyone. See our CALENDAR for the next meeting.

Open every day since 2007: offering locally sourced coffee, teas, baked goods, and a welcoming space for studying or events. Across Linden Street from First Presbyterian Church of Ann Arbor, Angell Elementary School and footsteps away from Chi Omega and seven other sororities and fraternity houses on the oddly-shaped lot bounded by South University. Washtenaw and Hill Streets.
The University Lutheran Chapel in Ann Arbor, Michigan was designed by architect Glen Paulsen in 1959; a local Ann Arbor architect known for his modernist work and close ties to the University of Michigan community. The chapel is one of his most celebrated designs and is widely regarded as an outstanding example of mid-20th-century ecclesiastical architecture in the Midwest. The dramatic hyperbolic-paraboloid roof and the integration of natural light through colored glass strips are signature elements of the building.
His work often emphasized clean lines, structural expression (e.g., exposed concrete and steel), and integration with natural surroundings, influenced by his time with Eero Saarinen and his teaching roles at the University of Michigan and Cranbrook Academy of Art. While the University Lutheran Chapel (1959) in Ann Arbor exemplifies his ecclesiastical modernism with its hyperbolic-paraboloid roof, below is a curated list of his other key projects, drawn from biographical records, architectural archives, and historical surveys. In the fullness of time his private practice from 1958 to 1969 morphed into TMP (Tarapata-MacMahon-Paulsen, 1969–1977).

“Ironically, on the 200th anniversary of our Bill of Rights, we find free speech under assault throughout the United States, including on some college campuses. The notion of political correctness has ignited controversy across the land. And although the movement arises from the laudable desire to sweep away the debris of racism and sexism and hatred, it replaces old prejudice with new ones. It declares certain topics off-limits, certain expression off-limits, even certain gestures off-limits.”
In 2024, a record-breaking 936 Thanksgiving Turkey Trots were hosted across all 50 U.S. states, attracting over 1.1 million participants and raising more than $3.6 million for charities. This figure comes from comprehensive data compiled by RunSignup, a leading race management platform that tracked events nationwide, showing a 21% increase from 2023. Florida led with 56 events, followed by other populous states like California and Texas.
For 2025 (as of late November), early indicators suggest a similar or slightly higher total, with at least 70 new races identified and low event churn (under 2%). Registration trends show events averaging 39% of 2024 totals already, pointing to continued growth in this beloved holiday tradition. These races—mostly 5K fun runs or walks—emphasize family participation, costumes, and community support, with over 90% held on Thanksgiving Day itself
