Dirichlet space of multiply connected domains with Weil-Petersson class boundaries [PDF]

open access: yes, 2014
The restricted class of quasicircles sometimes called the "Weil-Petersson-class" has been a subject of interest in the last decade. In this paper we establish a Sokhotski-Plemelj jump formula for WP-class quasicircles, for boundary data in a certain ...

Radiation‐Resistant Aluminum Alloy for Space Missions in the Extreme Environment of the Solar System

open access: yesAdvanced Materials, EarlyView.
A novel ultrafine‐grained aluminum crossover alloy exhibits unprecedented radiation resistance and mechanical stability under extreme irradiation doses up to 100 dpa. The exceptional resilience arises from thermodynamically stable T‐phase precipitates, enabling lightweight structural materials for next‐generation spacecraft and extraterrestrial ...

The distribution of the first elementary divisor of the reductions of a generic Drinfeld module of arbitrary rank [PDF]

open access: yes, 2013
Let $\psi$ be a generic Drinfeld module of rank $r \geq 2$. We study the first elementary divisor $d_{1, \wp}(\psi)$ of the reduction of $\psi$ modulo a prime $\wp$, as $\wp$ varies. In particular, we prove the existence of the density of the primes $\wp$

Microwave Absorption for Detection of Dirac Fermions in SnTe Films

open access: yesAdvanced Materials Interfaces, EarlyView.
Microwave absorption can detect Dirac fermions in samples exposed to the atmosphere. Results showed that although topological surface states are robust against environmental degradation, they are not detectable by electrical transport measurements. Hence, microwave absorption can detect Dirac fermions even in samples whose surfaces have deteriorated ...

On the Thermodynamics of Granular Media

open access: yes, 1992
A thermodynamic formulation for moving granular material is proposed. The fluctuations due to the constant flux and dissipation of energy are controlled in a `granular' ensemble by a pressure $\wp$ (`compression') which is conjugate to a contact volume (`

Perfusion Bioreactor Culture Incorporating Mechanical Confinement Enhances Mesenchymal Stem Cell Extracellular Vesicle Production and Wound Healing Potential

open access: yesAdvanced Materials Technologies, EarlyView.
Scalable manufacturing challenges and limited potency remain two of the most intransigent issues limiting clinical translation of EV therapeutics. Mechanical cues can induce phenotypic changes and increased vesiculation in EV source cells without the use of extraneous reagents, chemicals, and/or cargo, thereby potentially drastically improving the ...

Relationship Between a Homoderivation and a Semi-Derivation

open access: yesJournal of New Theory
Let $\wp$ be a ring. It is shown that if an additive mapping $\vartheta$ is a zero-power valued on $\wp$, then $\alpha:\wp\rightarrow\wp$ such that $\alpha=\vartheta+1$ is a bijective mapping of $\wp.$ The main aim of this study is to prove that ...

不同轮作模式对黄淮平原潮土区土壤养分及作物产量的影响

open access: yesShuitu Baochi Xuebao, 2022
通过大田试验,研究黄淮平原潮土区不同轮作方式对不同土层土壤速效养分和小麦产量构成因素及产量的影响。采用随机区组设置连续的小麦-玉米(WM-WM-WM)、1周期小麦-玉米+1周期小麦-大豆(WM-WS-WM)、1周期小麦-玉米+1周期小麦-夏花生(WM-WP-WM)、连续的小麦-夏花生(WP-WP-WP)和连续的小麦-大豆(WS-WS-WS)5个处理。结果表明,2017-2019年各处理土壤碱解氮、硝态氮、铵态氮、有效磷和速效钾含量在0-30 cm土层逐渐降低。随着栽培期限的增长,0-20 cm土层,WM-

Extremely large magnetoresistance in topologically trivial semimetal $\alpha$-WP$_2$

open access: yes, 2018
Extremely large magnetoresistance (XMR) was recently discovered in many non-magnetic materials, while its underlying mechanism remains poorly understood due to the complex electronic structure of these materials. Here, we report an investigation of the $\
