Recurrence-Free Survival Prediction for Anal Squamous Cell Carcinoma Chemoradiotherapy using Planning CT-based Radiomics Model

Kavli Affiliate: Jing Wang | First 5 Authors: Shanshan Tang, Kai Wang, David Hein, Gloria Lin, Nina N. Sanford | Summary: Objectives: Approximately 30% of non-metastatic anal squamous cell carcinoma (ASCC) patients will experience recurrence after chemoradiotherapy (CRT), and currently available clinical variables are poor predictors of treatment response. We aimed to develop a model […]

Cosmological Implications of Kalb-Ramond-Like-Particles

Kavli Affiliate: Edward W. Kolb | First 5 Authors: Christian Capanelli, Leah Jenks, Edward W. Kolb, Evan McDonough, | Summary: The Kalb-Ramond field is an antisymmetric, rank-two tensor field which most notably appears in the context of string theory, but has largely been unexplored in the context of cosmology. In this work, motivated by the […]

Computing SHAP Efficiently Using Model Structure Information

Kavli Affiliate: Ke Wang | First 5 Authors: Linwei Hu, Ke Wang, , , | Summary: SHAP (SHapley Additive exPlanations) has become a popular method to attribute the prediction of a machine learning model on an input to its features. One main challenge of SHAP is the computation time. An exact computation of Shapley values […]

Optical absorption spectra of metal oxides from time-dependent density functional theory and many-body perturbation theory based on optimally-tuned hybrid functionals

Kavli Affiliate: Jeffrey B. Neaton | First 5 Authors: Guy Ohad, Stephen E. Gant, Dahvyd Wing, Jonah B. Haber, María Camarasa-Gómez | Summary: Using both time-dependent density functional theory (TDDFT) and the “single-shot" $GW$ plus Bethe-Salpeter equation ($GW$-BSE) approach, we compute optical band gaps and optical absorption spectra from first principles for eight common binary […]

Topological synchronization of fractionalized spins

Kavli Affiliate: Joel E. Moore | First 5 Authors: Christopher W. Wächtler, Joel E. Moore, , , | Summary: The gapped symmetric phase of the Affleck-Kennedy-Lieb-Tasaki (AKLT) model exhibits fractionalized spins at the ends of an open chain. We show that breaking SU(2) symmetry and applying a global spin-lowering dissipator achieves synchronization of these fractionalized […]

Provably safe systems: the only path to controllable AGI

Kavli Affiliate: Max Tegmark | First 5 Authors: Max Tegmark, Steve Omohundro, , , | Summary: We describe a path to humanity safely thriving with powerful Artificial General Intelligences (AGIs) by building them to provably satisfy human-specified requirements. We argue that this will soon be technically feasible using advanced AI for formal verification and mechanistic […]

Control of Mechanical and Fracture Properties in Two-phase Materials Reinforced by Continuous, Irregular Networks

Kavli Affiliate: Chiara Daraio | First 5 Authors: Tommaso Magrini, Chelsea Fox, Adeline Wihardja, Athena Kolli, Chiara Daraio | Summary: Composites with high strength and high fracture resistance are desirable for structural and protective applications. Most composites, however, suffer from poor damage tolerance and are prone to unpredictable fractures. Understanding the behavior of materials with […]

Magnetic structures and turbulence in SN 1006 revealed with imaging X-ray polarimetry

Kavli Affiliate: Herman L. Marshall | First 5 Authors: Ping Zhou, Dmitry Prokhorov, Riccardo Ferrazzoli, Yi-Jung Yang, Patrick Slane | Summary: Young supernova remnants (SNRs) strongly modify surrounding magnetic fields, which in turn play an essential role in accelerating cosmic rays (CRs). X-ray polarization measurements probe magnetic field morphology and turbulence at the immediate acceleration […]

Sensory neurons couple arousal and foraging decisions in C. elegans

Kavli Affiliate: Cori Bargmann | Authors: Elias Scheer and Cori Bargmann | Summary: Foraging animals optimize feeding decisions by adjusting both common and rare behavioral patterns. Here, we characterize the relationship between an animal’s arousal state and a rare decision to leave a patch of bacterial food. Using long-term tracking and behavioral state classification, we […]
