Ultraviolet photon production rates of the first stars: Impact on the He II $λ$ 1640 Å emission line from primordial star clusters and the 21-cm signal from cosmic dawn

Posted by klaurent Cambridge

Kavli Affiliate: George Efstathiou | Summary:The first stars, the chemically pristine Population III, likely played an important role in heating the intergalactic medium during the epoch of cosmic dawn. The very high effective temperatures ($sim 10^5$ K) predicted for the most massive Population III stars could also give rise to tell-tale signatures in the emission-line […]

HLSDebugger: Identification and Correction of Logic Bugs in HLS Code with LLM Solutions

Posted by klaurent Peking

Kavli Affiliate: Jing Wang | First 5 Authors: Jing Wang, Jing Wang, , , | Summary: High-level synthesis (HLS) accelerates hardware design by enabling the automatic translation of high-level descriptions into efficient hardware implementations. However, debugging HLS code is a challenging and labor-intensive task, especially for novice circuit designers or software engineers without sufficient hardware […]

Enabling Pareto-Stationarity Exploration in Multi-Objective Reinforcement Learning: A Multi-Objective Weighted-Chebyshev Actor-Critic Approach

Posted by klaurent Tokyo

Kavli Affiliate: Jia Liu | First 5 Authors: Fnu Hairi, Fnu Hairi, , , | Summary: In many multi-objective reinforcement learning (MORL) applications, being able to systematically explore the Pareto-stationary solutions under multiple non-convex reward objectives with theoretical finite-time sample complexity guarantee is an important and yet under-explored problem. This motivates us to take the […]

Excitation and tunneling spectra of a fractional quantum Hall system in the thin cylinder limit

Posted by klaurent Berkeley

Kavli Affiliate: Joel Moore | Summary:The excitations of fractional quantum Hall effect (FQHE) states have been largely inaccessible to experimental probes until recently. New electron scanning tunneling microscopy (STM) results from Hu et.al. (arXiv:2308.05789) show promise in detecting and identifying these excited states via the local density of states (LDOS) spectrum. On a torus, there […]

Synteny-aware functional annotation of bacteriophage genomes with Phynteny

Posted by dbos UCSF

Kavli Affiliate: Robert Edwards | Authors: Susanna R Grigson, George Bouras, Bhavya Papudeshi, Vijini Mallawaarachchi, Michael J Roach, Przemyslaw Decewicz and Robert A Edwards | Summary: Accurate genome annotation is fundamental to decoding viral diversity and understanding bacteriophage biology; yet, the majority of bacteriophage genes remain functionally uncharacterised. Bacteriophage genomes often exhibit conserved gene order, […]

Style-Aware Blending and Prototype-Based Cross-Contrast Consistency for Semi-Supervised Medical Image Segmentation

Posted by klaurent Berkeley

Kavli Affiliate: Xiang Zhang | First 5 Authors: Chaowei Chen, Chaowei Chen, , , | Summary: Weak-strong consistency learning strategies are widely employed in semi-supervised medical image segmentation to train models by leveraging limited labeled data and enforcing weak-to-strong consistency. However, existing methods primarily focus on designing and combining various perturbation schemes, overlooking the inherent […]

Mosquito sex under lock and key

Posted by dbos Rockefeller

Kavli Affiliate: Leslie B. Vosshall | Authors: Leah Houri-Zeevi, Madison M. Walker, Jacopo Razzauti, Anurag Sharma, H. Amalia Pasolli and Leslie B. Vosshall | Summary: Female mosquitoes typically mate once in a lifetime, making this singular mating decision critically important for the female. Yet, mosquito mating has been historically viewed as male-guided, with the female […]
