$\text{Alpha}^2$: Discovering Logical Formulaic Alphas using Deep Reinforcement Learning [PDF]
arXivAlphas are pivotal in providing signals for quantitative trading. The industry highly values the discovery of formulaic alphas for their interpretability and ease of analysis, compared with the expressive yet overfitting-prone black-box alphas. In this work, we focus on discovering formulaic alphas.

Calibration for Weak Variance-Alpha-Gamma Processes [PDF]
arXiv, 2018 The weak variance-alpha-gamma process is a multivariate L\'evy process constructed by weakly subordinating Brownian motion, possibly with correlated components with an alpha-gamma subordinator. It generalises the variance-alpha-gamma process of Semeraro constructed by traditional subordination. We compare three calibration methods for the weak variance-

Yet another puzzle? the relation between price and performance in the mutual fund industry [PDF]
, 2006 Gruber (1996) drew attention to the puzzle that investors buy actively-managed funds even though, on average, they underperform index funds. We uncover another puzzling fact about the market for actively-managed equity mutual funds: funds with worse ...

Analyzing Electronic Excitations and Exciton Binding Energies in Y6 Films
Advanced Functional Materials, EarlyView.The Y6 molecule is used for increasing the efficiency of organic solar cells. The exciton binding energy is calculated for ensembles of Y6 molecules that are representative of the typically used films. The calculations show that the excitons typically spread out over many molecules.

Wetting of Surface Grafted Hydrophilic‐b‐Hydrophobic Block Copolymer Brushes
Advanced Functional Materials, EarlyView.The wetting properties of surface grafted diblock copolymer brushes are influenced by the thickness of the hydrophilic bottom block and the hydrophobic top block. The surface adapts in presence of water and the contact angles of the bottom block shine through. Abstract The wetting of diblock copolymer brushes by water is studied.

Advanced Functional Materials, EarlyView.Mesenchymal stem cell‐derived nanoghosts (MSC‐NGs) mimic naturally secreted extracellular vesicles (MSC‐EVs) in structure and physicochemical properties but can be synthesized at more translatable yields. As osteogenic agents, MSC‐NGs demonstrate superior outcomes compared to MSC‐EVs.
