Machine Learning‐Assisted Second‐Order Perturbation Theory for Chemical Potential Correction Toward Hubbard U Determination

Advanced Intelligent Discovery, EarlyView.
In this work, the Doubao large language model (LLM) is involved in the formula derivation processes for Hubbard U determination regarding the second‐order perturbations of the chemical potential. The core ML tool is optimized for physical domain knowledge, which is not limited to parameter prediction but rather serves as an interactive physical theory ...

水力压裂延迟活化断层的多场耦合数值模拟研究—以加拿大福克斯溪地区诱发地震为例

Dizhen xuebao
加拿大西部盆地的福克斯溪（Fox Creek）页岩气开采区自压裂开采以来，地震频度急剧增加，引发工业界和科学界的广泛关注。目前一些典型诱发地震案例的断层活化动力学机制尚未完全厘清。本文以2014年初福克斯溪地区Duvernay地层附近发生的地震群及构造为研究对象，开展地下断层受流体扰动而活化的多场耦合数值模拟研究。文中重点讨论的1号平台附近发生的诱发地震主要沿着两个较为清晰的发震断层发生，最大震级MW3.9事件发生于压裂井下方约1 km处的结晶基底内，并具有典型的延迟触发特点 ...

Candidate Phases for SU(2) Adjoint QCD$_4$ with Two Flavors from $\mathcal{N}=2$ Supersymmetric Yang-Mills Theory

, 2018
We study four-dimensional adjoint QCD with gauge group SU(2) and two Weyl fermion flavors, which has an $SU(2)_R$ chiral symmetry. The infrared behavior of this theory is not firmly established.

Electrohydrodynamic Fiber Pump With Dual‐Flow Channels

Advanced Intelligent Systems, EarlyView.
A dual‐channel electrohydrodynamic (EHD) fiber pump is introduced, which enables fluid flow inside and outside fully exposed helical electrodes. The dual‐channel design significantly enhances flow rate, pressure, and efficiency compared with the conventional design.

Coulomb stressing rate changes and seismicity dynamics associated with slow slip events in south-central Alaska

Earth and Planetary Physics
Two long-term slow slip events (SSEs) in Lower Cook Inlet, Alaska, were identified by Li SS et al. (2016). The earlier SSE lasted at least 9 years with Mw ~7.8 and had an average slip rate of ~82 mm/year.

Earthquake Growth Inhibited at Higher Coulomb Stress Change Rate at Groningen

Geophysical Research Letters
Gas extraction from the Groningen gas field resulted in significant induced seismicity. We analyze the magnitude‐frequency distribution of these earthquakes in space, time and in view of stress changes calculated based on gas production and reservoir ...
