Mellum: Production-Grade in-IDE Contextual Code Completion with Multi-File Project Understanding
We present the Mellum models family, open-weight code completion models designed for interactive use in JetBrains IDEs. Mellums have 4B parameters, adopt a Llama-style architecture, and are pre-trained on ~4T tokens of permissively licensed, multi-language code. Our studies show that (i) careful data curation and staged training significantly improve the model's quality, (ii) editor-critical capabilities such as context packing are necessary for high-quality suggestions, and (iii) a compact, ta…

Stability and optical quality of liquid crystal films as high repetition rate plasma mirrors in staged laser-plasma accelerators
Staging multiple laser-plasma accelerators (LPAs), each driven by its own laser pulse, is a promising technique for reaching higher particle energies than achievable in a single LPA. However, introducing subsequent laser pulses for post-acceleration in staged LPA geometries presents a significant challenge for conventional optics. Due to the focused, high-intensity nature of the laser beam interacting with the electron beam, the fluence on the coupling mirror surpasses the damage threshold of a…

Stacked Intelligent Metasurface for End-to-End OFDM System
Stacked intelligent metasurface (SIM) and dual-polarized SIM (DPSIM) enabled wave-domain signal processing have emerged as promising research directions for offloading baseband digital processing tasks and efficiently simplifying transceiver design. However, existing architectures are limited to employing SIM (DPSIM) for a single communication function, such as precoding or combining. To further enhance the overall performance of SIM (DPSIM)-assisted systems and achieve end-to-end (E2E) joint o…

Frustration-Enhanced Quantum Annealing Correction Models with Additional Inter-replica Interactions
Quantum annealing correction (QAC) models provide a promising approach for mitigating errors in quantum annealers. Previous studies have established that QAC models are crucial for ensuring the robustness of the ground state of the Ising model on hardware. In this work, the effects of QAC models incorporating replicas with additional interactions, specifically, the penalty spin model and the stacked model, are investigated for problems characterized by a small energy gap between the ground and …
