A Fuzzy Framework for Realized Volatility Prediction: Empirical Evidence From Equity Markets

open access: yesJournal of Forecasting, EarlyView.
ABSTRACT This study introduces a realized volatility fuzzy time series (RV‐FTS) model that applies a fuzzy c‐means clustering algorithm to estimate time‐varying c$$ c $$ latent volatility states and their corresponding membership degrees. These memberships are used to construct a fuzzified volatility estimate as a weighted average of cluster centroids.

A case report: Diagnosis and treatment of idiopathic hypertrophic pachymeningitis

open access: yesIbrain, Volume 11, Issue 1, Page 112-116, Spring 2025.
We reported a case of idiopathic hypertrophic dura meningitis diagnosed in our hospital. The patient repeatedly suffered from headaches, followed by blurred vision in the right eye. During this period, multiple sclerosis was considered for diagnosis, and it improved after hormone treatment.

Fast bootstrap and reliable readout using hidden references for DNA data storage

open access: yesiMeta, EarlyView.
This study provides a bootstrap readout framework for DNA data storage based on multiple‐fold hidden references. We employ a multi‐stage alignment and error correction strategy, transforming the de novo readout into a resequencing‐like workflow. Correlation to the hidden watermark reference identifies low‐error‐rate reads, and bit‐wise consensus ...
