Kavli Affiliate: Jie Shan | First 5 Authors: Hongying Feng, Jie Shan, Carlos E. Vargas, Sameer R. Keole, Jean-Claude M. Rwigema | Summary: We propose an oAPT workflow that incorporates all these functionalities and validate its clinical implementation feasibility with prostate patients. AI-based auto-segmentation tool AccuContourTM (Manteia, Xiamen, China) was seamlessly integrated into oAPT. Initial […]

Kavli Affiliate: Dan Luo | First 5 Authors: Mingyang Xu, Yujie Tan, Yurong Liang, Jiawen Zhi, Xiaoyang Guo | Summary: In this work, we have built an experimental setup to simulate the clock noise transmission with two spacecrafts and two optical links, and further demonstrated the extraction of picometer level signal drowned by the large […]

Kavli Affiliate: Zhiting Tian | First 5 Authors: Kushal Babel, Kushal Babel, , , | Summary: We introduce Mysticeti-C, the first DAG-based Byzantine consensus protocol to achieve the lower bounds of latency of 3 message rounds. Since Mysticeti-C is built over DAGs it also achieves high resource efficiency and censorship resistance. Mysticeti-C achieves this latency […]

Kavli Affiliate: Hector D. Abruna | Summary:Precious-metal-free spinel oxide electrocatalysts are promising candidates for catalyzing the oxygen reduction reaction (ORR) in alkaline fuel cells. In this theory-driven study, we use joint density-functional theory in tandem with supporting electrochemical measurements to identify a novel theoretical pathway for the ORR on cubic Co3O4 nanoparticle electrocatalysts. This pathway […]

Kavli Affiliate: Kyle Shen | First 5 Authors: L. Y. Shi, Zhenisbek Tagay, Jiahao Liang, Khoan Duong, Yi Wu | Summary: We present time-domain THz spectroscopy of thin films of the heavy-fermion superconductor CeCoIn$_5$. The complex optical conductivity is analyzed through a Drude model and extended Drude model analysis. Below the $approx$ 40 K Kondo […]

Kavli Affiliate: Jie Shan | First 5 Authors: Wenjin Zhao, Bowen Shen, Zui Tao, Sunghoon Kim, Patrick Knüppel | Summary: The interaction of a lattice of localized magnetic moments with a sea of conduction electrons in Kondo lattice models induces rich quantum phases of matter, such as Fermi liquids with heavily renormalized electronic quasiparticles, quantum […]

Kavli Affiliate: Alyosha Molnar | Summary:Artificial intelligence (AI) hardware is positioned to unlock revolutionary computational abilities across diverse fields ranging from fundamental science [1] to medicine [2] and environmental science [3] by leveraging advanced semiconductor chips interconnected in vast distributed networks. However, AI chip development has far outpaced that of the networks that connect them, […]

Kavli Affiliate: Brett Fors | Summary:Phase-segregated polyureas (PU) have received considerable interest due to their use as tough, impact-resistant coatings. Polyureas are favored for these applications due to their mechanical strain rate sensitivity and energy dissipation. Predicting and tailoring the mechanical response of PU remains challenging due to the complex interaction between its elastomeric and […]

Kavli Affiliate: Grace Xing | First 5 Authors: Len van Deurzen, Thai-Son Nguyen, Joseph Casamento, Huili Grace Xing, Debdeep Jena | Summary: We demonstrate epitaxial lattice-matched Al$_{0.89}$Sc$_{0.11}$N/GaN ten and twenty period distributed Bragg reflectors (DBRs) grown on c-plane bulk n-type GaN substrates by plasma-enhanced molecular beam epitaxy (PA-MBE). Resulting from a rapid increase of in-plane […]

Kavli Affiliate: Jie Shan | First 5 Authors: Phuong X. Nguyen, Liguo Ma, Raghav Chaturvedi, Kenji Watanabe, Takashi Taniguchi | Summary: Excitonic insulators (EIs), arising in semiconductors when the electron-hole binding energy exceeds the band gap, are a solid-state prototype for bosonic phases of matter. Unlike the charged excitations that are frozen and unable to […]
