Effect of charge regulation on the screening properties of zwitterionic macroion solutions

Posted by klaurent UCAS

Kavli Affiliate: Rudolf Podgornik | First 5 Authors: Rashmi Kandari, Rashmi Kandari, , , | Summary: Precisely controlling the surface charge of zwitterionic macromolecules is crucial for tailoring their properties and optimizing them for specific applications. Here, we present a generalized calculation scheme for determining the screening length in solutions containing zwitterionic macroions, where the […]

Screening properties of charge regulated zwitterionic macroion solutions

Posted by dbos UCAS

Kavli Affiliate: Rudolf Podgornik | First 5 Authors: Rashmi Kandari, Rudolf Podgornik, Sunita Kumari, , | Summary: We generalize a calculation scheme for obtaining the screening length in electrolytes and zwitterionic macroions subject to charge regulation by the former. We express the inverse screening parameter in terms of the derivative of the pressure with respect […]

The Kratos Framework for Heterogeneous Astrophysical Simulations: Ray Tracing, Reacting Flow and Thermochemistry

Posted by dbos Peking

Kavli Affiliate: Lile Wang | First 5 Authors: Lile Wang, , , , | Summary: Thermochemistry, ray-tracing radiation, and radiation-matter interactions are important processes which are computationally difficult to model in astrophysical simulations, addressed by introducing novel algorithms optimized for heterogeneous architectures in the Kratos framework. Key innovations include a stoichiometry-compatible reconstruction scheme for consistent […]

Dynamic Vision Mamba

Posted by dbos UCAS

Kavli Affiliate: Zheng Zhu | First 5 Authors: Mengxuan Wu, Zekai Li, Zhiyuan Liang, Moyang Li, Xuanlei Zhao | Summary: Mamba-based vision models have gained extensive attention as a result of being computationally more efficient than attention-based models. However, spatial redundancy still exists in these models, represented by token and block redundancy. For token redundancy, […]

Novel Polarimetric Analysis of Near Horizon Flaring Episodes in M87* in Millimeter Wavelength

Posted by dbos MIT

Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Razieh Emami, Matthew Liska, Koushik Chatterjee, Geoffrey C. Bower, Wystan Benbow | Summary: Recent multi-wavelength observations of M87* citep{2024A&A…692A.140A} revealed a high-energy $gamma$-ray flare without a corresponding millimeter counterpart. We present a theoretical polarimetric study to evaluate the presence and nature of a potential millimeter flare in […]
