Test-Time Scaling with Diffusion Language Models via Reward-Guided Stitching
Reasoning with large language models often benefits from generating multiple chains-of-thought, but existing aggregation strategies are typically trajectory-level (e.g., selecting the best trace or...

An $\mathcal{O}(\log N)$ Time Algorithm for the Generalized Egg Dropping Problem
The generalized egg dropping problem is a canonical benchmark in sequential decision-making. Standard dynamic programming evaluates the minimum number of tests in the worst case in $\mathcal{O}(K \...

SO3UFormer: Learning Intrinsic Spherical Features for Rotation-Robust Panoramic Segmentation
Panoramic semantic segmentation models are typically trained under a strict gravity-aligned assumption. However, real-world captures often deviate from this canonical orientation due to unconstrain...

A FUV - optical approach for studying hierarchical star formation in nearby galaxies with UVIT
Young star-forming clumps (SFCs) emit strongly in the ultraviolet (UV), making UV imaging ideal for detecting them. The Ultraviolet Imaging Telescope (UVIT) onboard AstroSat, with 1.5arcsec resolut...

From Blind Spots to Gains: Diagnostic-Driven Iterative Training for Large Multimodal Models
As Large Multimodal Models (LMMs) scale up and reinforcement learning (RL) methods mature, LMMs have made notable progress in complex reasoning and decision making. Yet training still relies on sta...

Performance and Experimental Analysis of Strain-based Models for Continuum Robots
Although strain-based models have been widely adopted in robotics, no comparison beyond the uniform bending test is commonly recognized to assess their performance. In addition, the increasing effo...

Testing beyond the Standard Model scenarios in next-generation long-baseline neutrino oscillation experiments
In this thesis, we assess the sensitivity of next-generation long-baseline neutrino oscillation experiments, DUNE, T2HK, and T2HKK, to three popular beyond the Standard Model (BSM) scenarios. Withi...

First measurement of the strong interaction scattering parameters for the $\mathbf{K^-d}$ and $\mathbf{K^+d}$ systems
Charged kaon--deuteron interactions offer a sensitive probe of the strangeness sector of QCD at low energy, particularly through their scattering parameters. Despite available theoretical predictio...

IRSDE-Despeckle: A Physics-Grounded Diffusion Model for Generalizable Ultrasound Despeckling
Ultrasound imaging is widely used for real-time, noninvasive diagnosis, but speckle and related artifacts reduce image quality and can hinder interpretation. We present a diffusion-based ultrasound...

Ideal random quantum circuits pass the LXEB test
We show that noiseless random quantum circuits pass the linear cross-entropy benchmark (LXEB) test with high probability. If the circuits are linear depth, and thus form unitary 4-designs, the LXEB...
