A Texture‐Free Multi‐Scale Model for Surface‐Based Rendering of Knitted Fabrics
Computer Graphics Forum, EarlyView.Abstract Knitted fabrics present unique challenges for realistic rendering due to their complicated structure and scale‐dependent appearance. Existing methods typically rely on explicit yarn geometry, which is computationally complex, or texture‐based representations that require heavy storage and precomputed maps. In this paper, we introduce the first

Measuring Thematic Funds Performance via an Approach Based on Observable and Latent Factors
European Financial Management, EarlyView.ABSTRACT This paper investigates whether thematic equity funds deliver abnormal performance relative to conventional global equity funds. Using Fama‐French models augmented with latent factors, we estimate fund‐level alphas, and apply the false discovery rate methodology to an estimated three‐group mixture distribution, separating good, null and bad ...

The findings reveal a declining trend in internal information exchange over time, with higher information flow in families characterized by greater managerial interaction.

A U‐Shaped Flow–Performance Sensitivity Across the Globe
European Financial Management, EarlyView.ABSTRACT Using a worldwide sample of equity mutual funds, we document a new stylized fact: the flow‐performance sensitivity (FPS) is greater for both bottom and top performance, compared to the middle. This “U‐shaped” FPS is especially strong in down markets, for small/mid‐cap funds, and in the latest decade. These results hold over quarterly or yearly

Financial Management, EarlyView.ABSTRACT Considering the time‐series dimension alongside the cross‐sectional dimension helps to almost entirely account for the idiosyncratic volatility (IVOL) puzzle. Based on a purely cross‐sectional approach, the previous literature shows that numerous candidate theories collectively fail to explain the puzzling finding that high‐IVOL stocks ...
