AlphaAgent: LLM-Driven Alpha Mining with Regularized Exploration to Counteract Alpha Decay [PDF]

arXiv
Alpha mining, a critical component in quantitative investment, focuses on discovering predictive signals for future asset returns in increasingly complex financial markets. However, the pervasive issue of alpha decay, where factors lose their predictive power over time, poses a significant challenge for alpha mining.

A Perspective on Powder Metallurgy and Additive Manufacturing of High‐Nitrogen Alloyed Stainless Steels

Advanced Engineering Materials, EarlyView.
This perspective article explores an innovative powder metallurgical approach to producing high‐nitrogen steels by utilizing a mixture of stainless steel and Si3N4. This mixture undergoes hot isostatic pressing followed by direct quenching. The article also examines adapting this method to laser powder bed fusion (PBF‐LB/M) to overcome nitrogen ...

Influence of Specific Ball‐Milling Energy on Mechanical and Corrosion Properties of Zn–0.2 Graphene Nanoplatelet Composites

Advanced Engineering Materials, Volume 27, Issue 7, April 2025.
In this study, the effect of specific ball‐milling energy (SBME) on the mechanical and corrosion properties of graphene nanoplatelets (GNPs) Zn matrix composites is presented. GNPs are uniformly dispersed in the Zn powder mixtures at the optimal SBME of 32.82 kJ g−1.

On non-uniqueness in the option valuation problem [PDF]

arXiv
It is known that the value of a call option in the case of constant elasticity processes (CEV) with the indicator $\alpha$ exceeding the critical $\alpha=1$ is determined in a non-unique way. We show how, based on an already existing mathematical theory concerning the correctness of boundary conditions for degenerate parabolic equations on the semi ...

Powder Metallurgy and Additive Manufacturing of High‐Nitrogen Alloyed FeCr(Si)N Stainless Steel

Advanced Engineering Materials, EarlyView.
The alloying element Nitrogen enhances stainless steel strength, corrosion resistance, and stabilizes austenite. This study develops austenitic FeCr(Si)N steel production via powder metallurgy. Fe20Cr and Si3N4 are hot isostatically pressed, creating an austenitic microstructure.

Asymptotic Error Distribution of the Euler Scheme for Fractional Stochastic Delay Differential Equations with Additive Noise [PDF]

arXiv
In this paper we consider the Euler scheme for a class of stochastic delay differential equations driven by a linear fractional $\alpha$-stable L\'evy motion with index $H\in(0,1)$. We establish the consistency of the scheme and study the limit distribution of the normalized error process. We show that in the rough case, i.e.

Effects of Creep in Titanium at Room Temperature during Tensile and Profilometry‐Based Indentation Plastometry Testing

Advanced Engineering Materials, Volume 27, Issue 9, May 2025.
This article concerns room temperature tensile testing, with a range of (nominal) strain rates, of three titanium alloys. Stress–strain curves are analyzed to obtain creep characteristics. Profilometry‐based indentation plastometry testing is also covered, using different penetration velocities, and correlations established with tensile data.

RiskMiner: Discovering Formulaic Alphas via Risk Seeking Monte Carlo Tree Search [PDF]

arXiv
The formulaic alphas are mathematical formulas that transform raw stock data into indicated signals. In the industry, a collection of formulaic alphas is combined to enhance modeling accuracy. Existing alpha mining only employs the neural network agent, unable to utilize the structural information of the solution space.
