TPR Domains Drive the Functional Phase Separation of HOP and its Regulation by Hsp90 and Hsp70
HOP is a cochaperone that facilitates client transfer between two major chaperones, Hsp90 and Hsp70. Emerging evidence, however, suggests that HOP plays additional roles in coordinating complex proteostasis networks. We demonstrate here that stress-dependent HOP foci are biomolecular condensates formed by liquid-liquid phase separation.
DTKG: Dual-Track Knowledge Graph-Verified Reasoning Framework for Multi-Hop QA
Announce Type: replace Abstract: Multi-hop reasoning for question answering (QA) plays a critical role in retrieval-augmented generation (RAG) for modern large language models (LLMs). The accurate answer can be obtained through retrieving relational structure of entities from knowledge graph (KG). Regarding the inherent relation-dependency and reasoning pattern, multi-hop reasoning can be in general classified into two categories: i) parallel fact-verification multi-hop reasoning question,...
‘Saaz is our gold’: the Czech scientists breeding hops that can survive a hotter Europe
Researchers are working to create new drought-resistant varieties of the ingredient that gives Czech pilsner its characterIt is the country that drinks more beer per capita than any other but in the last few years Czechia has been hit by droughts and heatwaves, which make it harder to grow the Saaz hops, one of the key ingredients that goes into the country’s world famous beer.At the Hop Research Institute, however, scientists are working to create new, climate-resilient hop varieties that...
Propeller-Assisted Robust 3D Hopping Robot with Hierarchical Force Allocation
Announce Type: new Abstract: Monopedal hopping robots are conceptually simple but highly dynamic and inherently unstable. Achieving robust 3D hopping is still difficult because ground reaction forces are available only during the short stance phase, while the robot is underactuated in flight.
HKVM-RAG: Key-Value-Separated Hypergraph Evidence Organization for Multi-Hop RAG
arXiv:2606.07218v1 Announce Type: new Abstract: Multi-hop RAG poses a data-engineering problem beyond passage matching: under fixed retrieval budgets, a system must organize retrieved text into evidence units that expose answer chains. Dense retrievers score passages independently, while graph-based memories make associations explicit but often rely on pairwise or entity-centered keys that fragment multi-hop evidence. We present HKVM-RAG, a key-value-separated evidence-organization layer.
‘Saaz is our gold’: the Czech scientists breeding hops that can survive a hotter Europe
Czech scientists are developing new, drought-resistant varieties of Saaz hops to combat the effects of increasing heatwaves and droughts in the country. These efforts are aimed at ensuring the continued production of the key ingredient for Czech pilsner, despite challenging climate conditions. The research is being conducted at the Hop Research Institute.
Multi-Hop Knowledge Composition is Bound by Pretraining Exposure
arXiv:2606.09338v1 Announce Type: new Abstract: Large Language Models fail at implicit multi-hop reasoning: a model answers "When was $X$ born?" and "Who is $Y$'s closest friend?" correctly but fails on "When was $Y$'s closest friend born?" in a single forward pass, even when both facts are perfectly memorized and individually retrievable.
Illinois man's Memorial Day weekend in Key West was derailed after he went bar hopping in a stolen police car
Imagine your unofficial start to summer taking place in Key West, Florida. You've made the trip for the Memorial Day weekend from suburban Chicago, and you've got plans to enjoy some of the local establishments.You have an evening of drinks planned on Saturday when all of a sudden those plans get derailed. Bar hopping was likely on the agenda, but there's no chance doing so in a stolen police car was ever mentioned.According to the Key West Police Department, John Mack, 38, of La Grange,...
RASER: Recoverability-Aware Selective Escalation Router for Multi-Hop Question Answering
arXiv:2606.02488v1 Announce Type: new Abstract: Multi-hop question-answering systems often use expensive retrieval on every question. They may decompose the question, run several retrieval rounds, or search through bridge entities before answering. All of these strategies rely on repeated LLM calls to rewrite or decompose the question, which increases extra token cost, and it is not fitting when the LLM budget is tight.
