Robust Estimation and Inference for Time‐Varying Unconditional Volatility

open access: yesJournal of Time Series Analysis, EarlyView.
ABSTRACT We derive a general and robust estimator of a large class of parametric specifications of time‐varying unconditional volatility of financial returns, both univariate and multivariate, and establish the Consistency and Asymptotic Normality (CAN) of the estimator.

Understanding extracellular vesicle biology, isolation, and characterization: The theory of EV‐erything

open access: yesPeriodontology 2000, EarlyView.
Abstract Background Extracellular vesicles (EVs), especially exosomes, are nanoparticles increasingly recognized as key regulators of intercellular communication in both physiological and pathological aspects. Despite rapid progress, inconsistencies in nomenclature, isolation, and characterization continue to restrict translational advancement.

Floating Platform Geometry as a Frequency‐Selective Mechanism for Triboelectric Wave Energy Harvesting

open access: yesSmartSys, Volume 2, Issue 3, September 2026.
ABSTRACT Ocean wave energy has enormous potential for sustainable power generation but conventional technologies often face challenges in efficiency, durability, and adaptability to specific sites. Triboelectric nanogenerators (TENGs) are able to convert irregular and low frequency water motion into electrical energy, but their performance depends on ...

Flexural Performance and Morphological Characterization of Graphene Nanoparticle‐Reinforced Polylactic Acid (PLA) Nanocomposites

open access: yesJournal of Polymer Science, Volume 64, Issue 16, Page 3427-3441, 15 August 2026.
PLA/GNP filaments containing 0–1.6 wt% graphene are produced by melt compounding and fabricated into flexural specimens using FDM. Their mechanical response and fracture morphology are evaluated through ASTM D790 three‐point bending tests and SEM. Increasing graphene loading promotes agglomeration and interlayer defects, reducing strength, stiffness ...
