Variable Sr Diffusion and Implications for Rb–Sr Biotite Geochronology

Journal of Metamorphic Geology, EarlyView.
ABSTRACT The rubidium–strontium (Rb–Sr) system has a long pedigree as a geochronological tool that relies on the application of an isochron approach. In particular, biotite contains strongly radiogenic Rb–Sr isotopes, and thus can yield meaningful crystallisation or cooling ages via this approach. However, the response of the Rb–Sr system in biotite to

Surface effects in multiband superconductors. Application to MgB$_2$

, 2001
Metals with many bands at the Fermi level can have different band dependent gaps in the superconducting state. The absence of translational symmetry at an interface can induce interband scattering and modify the superconducting properties.

Quantitative Strategy Based on Decision Tree and Bollinger Band

DEStech Transactions on Computer Science and Engineering, 2019
Because stock investors often invest blindly and emotionally, and the quantitative investment strategy is more rational and reliable, so the purpose of this paper is to establish a suitable quantitative strategy for investors. We selected six indicators as stock price forecasting indicators, constructed the model by using CART algorithm, Mallat ...

Powers and Practices in Labor Standards Enforcement

Regulation &Governance, EarlyView.
ABSTRACT Wage theft remains a pervasive problem internationally and within the United States. In response, worker advocates have sought stronger laws to deter violations and promote compliance. Yet formal authority alone may be insufficient; labor departments often fail to use the full extent of their legal authority to conduct vigorous enforcement ...

Temporal optimisation of signals emitted automatically by securities exchange indicators

Management Letters/Cuadernos de Gestión, 2020
Stock exchange indicators deliver buy/sell signals that enable analysts to improve the results of a strategy based strictly on fundamental analysis. Nonetheless, since the automatic implementation of signals as they appear may not yield optimal returns ...

Magnetic field dependence of the density of states in the multiband superconductor $\beta$-Bi$_2$Pd [PDF]

, 2015
We present very low temperature scanning tunneling microscopy (STM) experiments on single crystalline samples of the superconductor $\beta$-Bi$_2$Pd. We find a single fully isotropic superconducting gap.

A Novel Stock Price Prediction and Trading Methodology Based on Active Learning Surrogated with CycleGAN and Deep Learning and System Engineering Integration: A Case Study on TSMC Stock Data

FinTech
Technical analysis, reliant on statistics and charting tools, is a predominant method for predicting stock prices. However, given the impact of the joint effect of stock price and trading volume, analyses focusing solely on single factors at isolated ...
