The criteria for automorphisms on finite-dimensional algebras

open access: yesElectronic Research Archive
In this paper, we will establish a criterion for automorphisms of finite-dimensional algebras. As an application, we will describe all automorphisms of the single-parameter generalized quaternion algebra. Additionally, we will obtain all automorphisms of

FMint: Bridging Human Designed and Data Pretrained Models for Differential Equation Foundation Model for Dynamical Simulation

open access: yesAdvanced Theory and Simulations, EarlyView.
FMint is introduced as a multi‐modal foundation model that integrates human‐designed solvers and data‐driven methods for fast, accurate simulation of dynamical systems. FMint leverages in‐context learning within a transformer‐based framework to refine coarse numerical solutions.

Assessment and Comparative Study of Free and Commercial Numerical Software Packages for Lithium‐Ion Battery Modeling

open access: yesAdvanced Theory and Simulations, EarlyView.
This study evaluates the simulation capabilities of lithium‐ion battery (LIB) electrochemical simulation software packages. The benchmark simulation results reveal the impacts of parameter sensitivity to solver performance and stability. The guidelines to troubleshooting common solver failures at high current rates lowers the steep learning curve to ...

Label‐Free 3D Photoacoustic Imaging of Tumor Organoids for Volumetric Drug Screening

open access: yesAdvanced Science, EarlyView.
A label‐free organoid photoacoustic imaging (LFOPI) system is developed for precise volumetric drug screening evaluation. As a proof of concept, LFOPI's performance in chemotherapy and immunotherapy drug screening assays are further evaluated. The LFOPI offers unique non‐invasive, label‐free capabilities for tumor organoids, and contributes to the ...

Finiteness of Hermitian Levels of Some Algebras

open access: yesBoletim da Sociedade Paranaense de Matemática, 2011
We characterize the hermitian levels of quaternion and octonion algebrasand of an 8-dimensional algebra D over the ground field F, constructed using a weak version of the Cayley-Dickson double process.It is shown that all values of the hermitian levels ...

Chiral Selenium‐Integrated Multi‐Resonant Thermally Activated Delayed Fluorescent Emitters Showing Improved Reverse Intersystem Crossing Rate

open access: yesAngewandte Chemie, EarlyView.
The selenium‐based tBuCz‐DiKTaSe emitter containing a twisted ortho‐disposed tert‐butylcarbazole shows high ΦPL, suppressed ACQ, fast kRISC and is chiral. The OLEDs show high EQEmax and alleviated efficiency roll‐off compared to devices with carbonyl‐based MR‐TADF emitters.
