TripTide: A Benchmark for Adaptive Travel Planning under Disruptions
Karmakar, Priyanshu, Chaudhuri, Soumyabrata, Mallick, Shubhojit, Gupta, Manish, Jana, Abhik, Ghosh, Shreya
Recent efforts like TripCraft and TravelPlanner have advanced the use of Large Language Models ( LLMs) for personalized, constraint aware travel itinerary generation. Yet, real travel often faces disruptions. To address this, we present TripTide, the first benchmark evaluating LLM's ability to revise itineraries under realistic disruptions. TripTide models key dimensions such as disruption severity and traveler tolerance, enabling nuanced assessment of LLM adaptability to events like flight cancellations, weather closures, or overbooked attractions. We conduct a threefold evaluation. First, we introduce automatic metrics including Preservation of Intent (how well the revised plan maintains feasibility and goals), Responsiveness (promptness and appropriateness of disruption handling), and Adaptability (semantic, spatial, and sequential divergence between original and revised plans). Second, we apply an LLM-as-a-judge approach to automatically assess revision quality. Third, we perform manual expert evaluation to verify whether revisions preserve semantic, spatial, sequential, and responsive aspects. Our experiments show that LLMs maintain strong sequential consistency and semantic stability, while spatial deviations are larger for shorter trips but decrease with longer ones, indicating that extended plans encourage better geographic coherence. However, disruption-handling ability declines as plan length increases, highlighting limits in LLM robustness. TripTide establishes a benchmark for evaluating adaptability, personalization, and resilience in LLM-based travel planning under real-world uncertainty.

ExoNav II: Design of a Robotic Tool with Follow-the-Leader Motion Capability for Lateral and Ventral Spinal Cord Stimulation (SCS)
Moradkhani, Behnam, Kheradmand, Pejman, Jella, Harshith, Klein, Joseph, Zemmar, Ajmal, Chitalia, Yash
Spinal cord stimulation (SCS) electrodes are traditionally placed in the dorsal epidural space to stimulate the dorsal column fibers for pain therapy. Recently, SCS has gained attention in restoring gait. However, the motor fibers triggering locomotion are located in the ventral and lateral spinal cord. Currently, SCS electrodes are steered manually, making it difficult to navigate them to the lateral and ventral motor fibers in the spinal cord. In this work, we propose a helically micro-machined continuum robot that can bend in a helical shape when subjected to actuation tendon forces. Using a stiff outer tube and adding translational and rotational degrees of freedom, this helical continuum robot can perform follow-the-leader (FTL) motion. We propose a kinematic model to relate tendon stroke and geometric parameters of the robot's helical shape to its acquired trajectory and end-effector position. We evaluate the proposed kinematic model and the robot's FTL motion capability experimentally. The stroke-based method, which links tendon stroke values to the robot's shape, showed inaccuracies with a 19.84 mm deviation and an RMSE of 14.42 mm for 63.6 mm of robot's length bending. The position-based method, using kinematic equations to map joint space to task space, performed better with a 10.54 mm deviation and an RMSE of 8.04 mm. Follow-the-leader experiments showed deviations of 11.24 mm and 7.32 mm, with RMSE values of 8.67 mm and 5.18 mm for the stroke-based and position-based methods, respectively. Furthermore, end-effector trajectories in two FTL motion trials are compared to confirm the robot's repeatable behavior. Finally, we demonstrate the robot's operation on a 3D-printed spinal cord phantom model.

Company behind Louisville's disastrous rollout of a new school bus system had similar issues in Ohio last year
Fox News Flash top headlines are here. Check out what's clicking on Foxnews.com. The company behind a disastrous change to a Kentucky city's school bus routes that resulted in more than a week of canceled classes had similar problems in two cities in neighboring Ohio last year. Touting its connections to the Massachusetts Institute of Technology, bus-routing vendor AlphaRoute pitched its mathematical models and machine-learning technology as a way of saving money and smoothing out complex bus routes in Louisville, Kentucky, and school districts across the U.S. But real-world problems often got in the way.

Logistical crisis prompts school closures in Louisville as new bus route overhaul hits snags
Fox News Flash top headlines are here. Check out what's clicking on Foxnews.com. A total overhaul of bus routes for Louisville's school district turned into a logistical meltdown on the first day of classes because the new plan created too steep a learning curve for the system, district officials said Friday, forcing administrators to cancel two days of classes and leaving parents and state legislators fuming. It took just one disastrous day for Jefferson County Public Schools leaders to completely reexamine the transportation plan for Kentucky's largest district, which serves 96,000 students. Some kids arrived home hours late on Wednesday, and classes were canceled Thursday and Friday.

In the US, the AI Industry Risks Becoming Winner-Take-Most
A new study warns that the American AI industry is highly concentrated in the San Francisco Bay Area and that this could prove to be a weakness in the long run. The Bay leads all other regions of the country in AI research and investment activity, accounting for about one-quarter of AI conference papers, patents, and companies in the US. Bay Area metro areas see levels of AI activity four times higher than other top cities for AI development. "When you have a high percentage of all AI activity in Bay Area metros, you may be overconcentrating, losing diversity, and getting groupthink in the algorithmic economy. It locks in a winner-take-most dimension to this sector, and that's where we hope that federal policy will begin to invest in new and different AI clusters in new and different places to provide a balance or counter," Mark Muro, policy director at the Brookings Institution and the study's coauthor, told WIRED.

Kentucky banned 'Fortnite' from esports because of guns but swords and lasers are fine
LOUISVILLE – Even after Kentucky High School Athletic Association Commissioner Julian Tackett sent out an email notifying school officials that esports teams may not participate in the video game "Fortnite," there was nothing to be done among schools here. That's because "Fortnite," an online video game developed by Epic Games and released in 2017, was never included among the games played by Kentucky students in high school competitions. "Fortnite" is a third-person shooter game that doesn't include any blood, injuries or dead bodies, but nevertheless was given a Teen rating for violence by the Entertainment Software Rating Board. Epic Games and PlayVS, a software company that provides a platform for competitive esports, last week announced last Wednesday a partnership to introduce a competitive league for "Fortnite" across high schools and colleges. "There is no place for shooter games in our schools," Tackett said, adding that the KHSAA and the National Federation of State High School Associations had no knowledge that "Fortnite" was being added as part of the competition platform and are "strongly against it."

Industries at risk: Carmakers and clothing makers are using AI for advanced manufacturing on production lines -- that's far more complex than the routine, task-oriented automation that most robots power. Cities highly exposed to AI disruption: Established or emerging tech hubs like San Jose, Seattle, Salt Lake City, Boulder and Huntsville. Also agricultural centers like Madera and Salinas in California, and logistics and advanced manufacturing hubs like Greenville, S.C.; Detroit; and Louisville.

It's official: Microsoft's regional artificial intelligence hub has a home in Louisville
The report states that 28.6% of Louisville's jobs are at "high risk" of being automated. A central purpose in this partnership is to make sure Louisville is well-equipped for the technological revolution, according to Grace Simrall, chief of Civic Innovation and Technology for Louisville Metro Government. "Experts know that automation and AI are coming," Simrall previously told The Courier Journal. "They know that they will probably destroy tasks and potentially even jobs faster than we can replace them if we don't do something about it." Fischer also announced Wednesday afternoon that Ben Reno-Weber, a social entrepreneur and project director of the independent, non-partisan civic data initiative The Greater Louisville Project, will serve as director of the Future of Work Initiative.
In era of online retail, Black Friday still lures American crowds
NEW YORK – It would have been easy to turn on their computers at home over plates of leftover turkey and take advantage of the Black Friday deals most retailers now offer online. But across the country, thousands of shoppers flocked to stores on Thanksgiving or woke up before dawn the next day to take part in this most famous ritual of American consumerism. Shoppers spent their holiday lined up outside the Mall of America in Bloomington, Minnesota, by 4 p.m. Thursday, and the crowd had swelled to 3,000 people by the time doors opened at 5 a.m. In Ohio, a group of women was so determined, they booked a hotel room Thursday night to be closer to the stores. In New York City, one woman went straight from a dance club to a department store in the middle of the night.
