Influence of Nanoparticles on Dielectric Properties of High‐Voltage Epoxy‐Based Nanocomposite Insulators: Simulation and Experimental Analysis

open access: yesEnergy Science &Engineering, EarlyView.
ABSTRACT There is a need to develop an improved insulating material that surpasses traditional insulators in terms of insulation and efficient operation under extreme weather conditions. Epoxy nanocomposites (NCs) have gained considerable attention due to their intrinsic material properties.

Shock‐Triggered Asymmetric Response Stochastic Volatility

open access: yesJournal of Forecasting, EarlyView.
ABSTRACT We propose a novel asymmetric stochastic volatility model (STAR‐SV) in which the leverage parameter adjusts to the magnitude of past shocks. This flexible specification captures both the leverage effects and their propagation more effectively than standard asymmetric volatility models.

Laplace-Laplace analysis of the fractional Poisson process

open access: yes, 2012
We generate the fractional Poisson process by subordinating the standard Poisson process to the inverse stable subordinator. Our analysis is based on application of the Laplace transform with respect to both arguments of the evolving probability ...

Forecasting With Machine Learning Shadow‐Rate VARs

open access: yesJournal of Forecasting, EarlyView.
ABSTRACT Interest rates are fundamental in macroeconomic modeling. Recent studies integrate the effective lower bound (ELB) into vector autoregressions (VARs). This paper studies shadow‐rate VARs by using interest rates as a latent variable near the ELB to estimate their shadow‐rate values.

The interplay between tissue‐resident microbiome and host proteins by integrated multi‐omics during progression of colorectal adenoma to carcinoma

open access: yesiMeta, EarlyView.
This study integrated metagenomic and proteomic profiling of 185 colorectal tissue samples—spanning adenoma (A), tumor (T), and para‐tumor (P)—to characterize multi‐kingdom microbiome and host protein dynamics in colorectal cancer (CRC). In total, 4057 bacterial, 61 fungal, 108 archaeal, and 374 viral species were identified, revealing CRC‐specific ...

Application of a hybrid pseudospectral method to a new two-dimensional multi-term mixed sub-diffusion and wave-diffusion equation of fractional order

open access: yesNetworks and Heterogeneous Media
In the current study, a novel multi-term mixed sub-diffusion and wave-diffusion model was considered. The new model has a unique time-space coupled derivative in addition to having the diffusion-wave and sub-diffusion terms concurrently.

Rough Quasi‐Conformal Mapping for Realizing Omnidirectional Light Wave Manipulation in Lower‐Index Meta‐Lens

open access: yesLaser &Photonics Reviews, EarlyView.
A rough quasi‐conformal mapping strategy breaks the rigid geometric constraints of transformation optics. By trading perfect local angle preservation for a dramatically reduced refractive index, this design paradigm enables the creation of ultra‐flat, wide‐angle, and even omnidirectional lenses that are both high‐performance and manufacturable, opening

Polymer Dispersity Determination by Diffusion‐Ordered Spectroscopy (DOSY)

open access: yesMacromolecular Rapid Communications, EarlyView.
The use of DOSY‐NMR to determine the dispersity of polymer molar mass distributions is explored and correlations between NMR and size exclusion chromatography are determined. ABSTRACT The dispersity (Ð) of a polymer is one of its most important characteristics.
