Some hypothesis on commonality in liquidity: New evidence from the Chinese stock market [PDF]
In this paper, we examine four specific hypotheses relating to commonality in liquidity on the Chinese stock markets. These hypotheses are: (a) that market-wide liquidity determines liquidity of individual stocks; (b) that liquidity varies with firm size;

Advanced Materials, EarlyView.Oxygen‐releasing hydrogels are widely used to support cell survival in 3D cultures and to promote wound healing. However, incorporating catalase to convert H2O2 into O2 often generates additional oxygen bubbles, leading to material instability which rarely addressed.

Short-term returns and the predictability of Finnish stock returns [PDF]
The predictability of Finnish stock returns is studied using the framework of Ferson and Harvey (1993). We use a conditional asset pricing model where risk premia and risk sensitivities are conditioned on a range of financial information variables.

AI–Guided 4D Printing of Carnivorous Plants–Inspired Microneedles for Accelerated Wound Healing
Advanced Materials, EarlyView.This work presents an artificial intelligence (AI)‐guided 4D‐printed microneedle platform inspired by carnivorous plants for wound healing. A thermo‐responsive shape memory polymer enables body temperature–triggered self‐coiling for autonomous wound closure.

Neutron Reflectometry and Compression of Graded Hydrogel Surfaces
Advanced Materials Interfaces, EarlyView.Highly‐entangled and covalently‐crosslinked hydrogels with thin and thick surface gel layers are compressed in neutron reflectometry experiments. Surface gel layer thickness dictates the extent to which the polymer network at the surface of a hydrogel collapses, while crosslinking chemistry, and therefore elastic modulus, impacts the pressure at which ...

Why Do REITs Repurchase Stock? Extricating the Effect of Managerial Signaling in Open Market Share Repurchase Announcements [PDF]
This paper explores the effect of stock repurchase announcements on equity returns for publicly traded real estate investment trusts (REITs). In addition to providing analysis of the corporate decision to repurchase shares, the study of share repurchases

Advanced Materials Technologies, EarlyView.A custom shape memory polymer material selection process relates quantitative application criteria (e.g., compression garment yarns) to material characterization information. The selected materials are manufactured into yarn geometries, which expand the design space by creating structural stress‐strain profiles beyond the nominal material stress‐strain

Dynamic Capital Structure: the Case of Hufvudstaden [PDF]
This paper introduces a new approach of testing capital structure hypothesis on a firm specific level. Johansen’s procedure for cointegration testing is employed to test theories of optimal capital structure.

Advanced Optical Materials, EarlyView.Multimodal perovskite nanocrystals enable optical thermometry across multiple excitation and emission regimes, spanning the UV–Vis–NIR spectral range. By combining upconversion, downshifting, and persistent luminescence, the platform bridges conventional Boltzmann and non‐Boltzmann thermometric approaches.

Stock market development and financial intermediaries : stylized facts [PDF]
World stock markets are booming. Between 1982 and 1993, stock market capitalization grew from $2 trillion to $10 trillion, an average 15 percent a year. A disproportionate amount of this growth was in emerging stock markets, which rose from 3 percent of ...
