Coherent phonon motions and ordered vacancy compound mediated quantum path interference in Cu-poor CuIn$_{x}$Ga$_{(1-x)}$Se$_2$ (CIGS) with attosecond transient absorption

Posted by dbos June 5, 2025June 9, 2025Berkeley, This Week: Nanoscience

Kavli Affiliate: Peidong Yang | First 5 Authors: Hugo Laurell, Jonah R. Adelman, Elizaveta Yakovleva, Carl Hägglund, Kostiantyn Sopiha | Summary: In this study, coherent phonon motion is observed in bandgap excited CuIn$_{x}$Ga$_{(1-x)}$Se$_2$ (CIGS) utilizing extreme ultraviolet (XUV) attosecond transient absorption spectroscopy across the Se M$_{4,5}$ absorption edge. Two frequencies of coherent phonon motion are […]

Fentanyl reinforcement history has sex-specific effects on multi-step decision-making

Posted by dbos June 5, 2025June 9, 2025Hopkins, This Week: Neuroscience

Kavli Affiliate: Patricia Janak | Authors: Eric Garr, Yifeng Cheng, Andy Dong and Patricia H. Janak | Summary: It is commonly thought that drug addiction involves a transition to habitual control of action, where the choice to consume drugs becomes automatized and reflects a failure to deliberate over possible negative outcomes. Determining whether the pursuit […]

Backward Responsibility in Transition Systems Beyond Safety

Posted by dbos June 5, 2025June 9, 2025Cornell, This Week: Nanoscience

Kavli Affiliate: Johannes Lehmann | First 5 Authors: Christel Baier, Rio Klatt, Sascha Klüppelholz, Johannes Lehmann, | Summary: As the complexity of software systems rises, methods for explaining their behaviour are becoming ever-more important. When a system fails, it is critical to determine which of its components are responsible for this failure. Within the verification […]

Structured Labeling Enables Faster Vision-Language Models for End-to-End Autonomous Driving

Posted by dbos June 5, 2025June 9, 2025Peking, This Week: Astrophysics

Kavli Affiliate: Ke Wang | First 5 Authors: Hao Jiang, Chuan Hu, Yukang Shi, Yuan He, Ke Wang | Summary: Vision-Language Models (VLMs) offer a promising approach to end-to-end autonomous driving due to their human-like reasoning capabilities. However, troublesome gaps remains between current VLMs and real-world autonomous driving applications. One major limitation is that existing […]
