Trans-dimensional Hamiltonian model selection and parameter estimation from sparse, noisy data

Posted by klaurent Delft

Kavli Affiliate: Tim H. Taminiau | Summary:High-throughput characterization often requires estimating parameters and model dimension from experimental data of limited quantity and quality. Such data may result in an ill-posed inverse problem, where multiple sets of parameters and model dimensions are consistent with available data. This ill-posed regime may render traditional machine learning and deterministic […]

Data-Driven Design-Test-Make-Analyze Paradigm for Inorganic Crystals: Ultrafast Synthesis of Ternary Oxides

Posted by klaurent Berkeley

Kavli Affiliate: Kristin Persson | Summary:Data-driven methodologies hold the promise of revolutionizing inorganic materials discovery, but they often face challenges due to discrepancies between theoretical predictions and experimental validation. In this work, we present an end-to-end discovery framework that leverages synthesizability, oxidation state probability, and reaction pathway calculations to guide the exploration of transition metal […]

Lithium and Vanadium Intercalation into Bilayer V2Se2O: Ferrimagnetic-Ferroelastic Multiferroics and Anomalous and Spin Transport

Posted by klaurent UCAS

Kavli Affiliate: Long Zhang | First 5 Authors: , , , , | Summary: Spin splitting in emerging altermagnets is non-relativistic and momentum-dependent, yet energy-independent, and localized in momentum space, posing challenges for practical applications. Here, we propose an intercalation-driven paradigm for altermagnets to attain ameliorative electronic structures, multiferroic characteristics, and anomalous and spin transport […]

IntuiTF: MLLM-Guided Transfer Function Optimization for Direct Volume Rendering

Posted by klaurent Peking

Kavli Affiliate: Ke Wang | First 5 Authors: Yiyao Wang, Yiyao Wang, , , | Summary: Direct volume rendering (DVR) is a fundamental technique for visualizing volumetric data, where transfer functions (TFs) play a crucial role in extracting meaningful structures. However, designing effective TFs remains unintuitive due to the semantic gap between user intent and […]

Exact linear theory of perturbation response in a space- and feature-dependent cortical circuit model

Posted by dbos Columbia

Kavli Affiliate: Kenneth Miller | Authors: Ho Yin Chau, Kenneth D Miller and Agostina Palmigiano | Summary: What are the principles that govern the responses of cortical networks to their inputs and the emergence of these responses from recurrent connectivity? Recent experiments have probed these questions by measuring cortical responses to two-photon optogenetic perturbations of […]

Empirical Models of the Time Evolution of SPX Option Prices

Posted by klaurent Caltech

Kavli Affiliate: David Hsieh| Summary:The key objective of this paper is to develop an empirical model for pricing SPX options that can be simulated over future paths of the SPX. To accomplish this, we formulate and rigorously evaluate several statistical models, including neural network, random forest, and linear regression. These models use the observed characteristics […]
