Bidirectional Representations Augmented Autoregressive Biological Sequence Generation:Application in De Novo Peptide Sequencing

Posted by klaurent Berkeley

Kavli Affiliate: Xiang Zhang | First 5 Authors: Xiang Zhang, Xiang Zhang, , , | Summary: Autoregressive (AR) models, common in sequence generation, are limited in many biological tasks such as de novo peptide sequencing and protein modeling by their unidirectional nature, failing to capture crucial global bidirectional token dependencies. Non-Autoregressive (NAR) models offer holistic, […]

Variable-Rate Texture Compression: Real-Time Rendering with JPEG

Posted by klaurent Delft

Kavli Affiliate: Michael Wimmer | First 5 Authors: Elias Kristmann, Elias Kristmann, , , | Summary: Although variable-rate compressed image formats such as JPEG are widely used to efficiently encode images, they have not found their way into real-time rendering due to special requirements such as random access to individual texels. In this paper, we […]

Pareto-optimality of Majoranas in hybrid platforms

Posted by klaurent Delft

Kavli Affiliate: Michael Wimmer | First 5 Authors: Juan Daniel Torres Luna, Juan Daniel Torres Luna, , , | Summary: To observe Majorana bound states, and especially to use them as a qubit, requires careful optimization of competing quality metrics. We systematically compare Majorana quality in proximitized semiconductor nanowires and quantum dot chains. Using multi-objective […]

A Narwhal-Inspired Sensing-to-Control Framework for Small Fixed-Wing Aircraft

Posted by klaurent Caltech

Kavli Affiliate: Morteza Gharib | First 5 Authors: Fengze Xie, Fengze Xie, , , | Summary: Fixed-wing unmanned aerial vehicles (UAVs) offer endurance and efficiency but lack low-speed agility due to highly coupled dynamics. We present an end-to-end sensing-to-control pipeline that combines bio-inspired hardware, physics-informed dynamics learning, and convex control allocation. Measuring airflow on a […]

A Giant Peanut-shaped Ultra-High-Energy Gamma-Ray Emitter Off the Galactic Plane

Posted by klaurent Caltech

Kavli Affiliate: Wei Gao | First 5 Authors: Zhen Cao, Zhen Cao, , , | Summary: Ultra-high-energy (UHE), exceeding 100 TeV (10^12 electronvolts), gamma-rays manifests extreme particle acceleration in astrophysical sources. Recent observations by gamma-ray telescopes, particularly by the Large High Altitude Air Shower Observatory (LHAASO), have revealed a few tens of UHE sources, indicating […]

Real-Space Quantification of Exciton Localization in Acene Crystals Using Wannier Function Decomposition

Posted by klaurent Berkeley

Kavli Affiliate: Jeffrey B. Neaton | First 5 Authors: Zui Tao, Zui Tao, , , | Summary: We introduce the Wannier function decomposition of excitons (WFDX) method to quantify exciton localization in solids within the ab initio Bethe-Salpeter equation framework. By decomposing each Bloch exciton wavefunction into products of single-particle electron and hole maximally localized […]

Commensurate-incommensurate Mott transition without magnetic field: emergence of nematic Luttinger liquid in XXZ chain

Posted by klaurent Delft

Kavli Affiliate: Natalia Chepiga | First 5 Authors: Julien Fitouchi, Julien Fitouchi, , , | Summary: We investigate the zero-magnetization phase diagram of a spin-1/2 chain with competing ferromagnetic nearest-neighbor and antiferromagnetic next-nearest-neighbor exchange couplings in the strongly interacting regime. Using density matrix renormalization group (DMRG) simulations, we discover two successive commensurate-incommensurate transitions of the […]

Flow4Agent: Long-form Video Understanding via Motion Prior from Optical Flow

Posted by klaurent Caltech

Kavli Affiliate: Wei Gao | First 5 Authors: Ruyang Liu, Ruyang Liu, , , | Summary: Long-form video understanding has always been a challenging problem due to the significant redundancy in both temporal and spatial contents. This challenge is further exacerbated by the limited context length of Multimodal Large Language Models (MLLMs). To address this […]
