Tensor Changepoint Detection and Eigenbootstrap

open access: yesJournal of Time Series Analysis, EarlyView.
ABSTRACT Tensor data consisting of multivariate outcomes over the items and across the subjects with longitudinal and cross‐sectional dependence are considered. A completely distribution‐free and tweaking‐parameter‐free detection procedure for changepoints at different locations is designed, which does not require training data.

The fundamental theorem of asset pricing with and without transaction costs

open access: yesMathematical Finance, Volume 35, Issue 2, Page 567-609, April 2025.
Abstract We prove a version of the fundamental theorem of asset pricing (FTAP) in continuous time that is based on the strict no‐arbitrage condition and that is applicable to both frictionless markets and markets with proportional transaction costs. We consider a market with a single risky asset whose ask price process is higher than or equal to its ...

Impact of type 1 diabetes on binocular vision: Evidence from a comparative analysis

open access: yesAnnals of the New York Academy of Sciences, EarlyView.
Individuals with type 1 diabetes (T1D) without retinopathy exhibit significant impairments in binocular vision, including reduced near point of convergence, fusional vergence, vergence facility, and AC/A ratio. The prevalence of non‐strabismic binocular vision disorders is higher in T1D, emphasizing the need for comprehensive optometric evaluations ...
