Strangeness suppression, the meson and spin correlations from exact strangeness conservation at the quark level
P. Castorina, H. Satz
In small collision systems strange hadrons are suppressed, and the suppression grows with the number of strange quarks. Exact strangeness conservation in a finite volume accounts f…
TopoFuse: Topology-Aware Tri-Planar Fusion for 3D Cryo-Electron Tomography Segmentation
Rohit Kumar Salla, Neelesh Gupta, Xingjian Li +1
Automated segmentation of cryo-electron tomograms routinely produces masks that are voxel-accurate but topologically broken: membranes fragment, organelles merge into one another,…
Learning When to Stop: Prefix-Optimal Dynamic Diffusion Policies for Continuous Control
Rohit Kumar Salla, Manoj Saravanan, Simon Stepputtis
Diffusion policies are a powerful policy class for continuous control, but their iterative denoising process creates a substantial computational bottleneck. Reducing this cost requ…
CrossQ: Task-Aligned Cross-Token Conditional Quantization for Late Interaction Retrieval
Rohit Kumar Salla, Manoj Saravanan, Ramya Manasa Amancherla
Late-interaction retrievers like ColBERT achieve high quality but suffer from large multi-vector indices. Standard compression minimizes token reconstruction error, while ranking d…
Quantifying Cross-Query Contradictions in Multi-Query LLM Reasoning
Rohit Kumar Salla, Ramya Manasa Amancherla, Manoj Saravanan
Large language models frequently produce mutually inconsistent answers when reasoning over multiple related queries. We study case-file logical consistency: maintaining a globally…
Beyond Hallucinations: A Composite Score for Measuring Reliability in Open-Source Large Language Models
Rohit Kumar Salla, Manoj Saravanan, Shrikar Reddy Kota
Large Language Models (LLMs) like LLaMA, Mistral, and Gemma are increasingly used in decision-critical domains such as healthcare, law, and finance, yet their reliability remains u…
