Analyzing Key Objectives in Human-to-Robot Retargeting for Dexterous Manipulation
Kinematic retargeting from human hands to robot hands is essential for transferring dexterity from humans to robots in manipulation teleoperation and imitation learning. However, due to mechanical differences between human and robot hands, completely reproducing human motions on robot hands is impossible. Existing works on retargeting incorporate various optimization objectives, focusing on different aspects of hand configuration. However, the lack of experimental comparative studies leaves the…

Raiders' Brock Bowers Set to Cash In Big In Future https://www.si.com/nfl/raiders/las-vegas-brock-bowers-puka-nacua-justin-jefferson-jamarr-chase

"When the Trump regime took over in January and Elon Musk's data-raiders started hacking federal agencies of various kinds, a group chat in which I participate started speculating about what kinds of terrible things this crowd might do. One member of the group wondered if the hacking might include the Social Security Administration's "death master file" – a list of people, presumably deceased, who would not receive any federal benefits and whose names and other identifying information would be flagged so that financial institutions would refuse to serve them.
What if, the conversation continued, the infamously cruel and paranoid regime decided to add living persons to the death master list? Doing so would destroy people's actual lives – which might make it just what a vicious government would do."

On the Linear Programming Model for Dynamic Stochastic Matching and Its Application on Pricing
Important pricing problems in centralized matching markets -- such as carpooling and food delivery platforms -- often exhibit a bi-level structure. At the upper level, the platform sets prices for different types of agents (e.g., riders with various origins and destinations, or delivery orders from diverse restaurants to customer locations). The lower level then matches converted agents to minimize operational costs, such as pooling riders with similar itineraries into the same vehicle or conso…

Surfacing Pathological Behaviors in Language Models
We train reinforcement learning (RL) agents to craft realistic natural-language prompts that elicit specified behaviors in frontier open-weight models (Llama 3.1/4, Qwen 2.5, and DeepSeek-V3), using a proposed variational lower bound to guide the search.

Russland: Noch kein Datum für neue direkte Gespräche
Die russische Führung hat nach eigenen Angaben noch kein konkretes Datum für eine Fortsetzung der direkten Verhandlungen mit der Ukraine im Auge. Ein Termin für die nächste Gesprächsrunde werde vereinbart, sobald beide Seiten bereit seien, sagte Präsidialamtssprecher Dmitri Peskow der Nachrichtenagentur Reuters zufolge. Zunächst müssten beide Seiten die ausgetauschten Vorsc…
