Comparison of wavelet approximation order in different smoothness spaces

International Journal of Mathematics and Mathematical Sciences, 2006
In linear approximation by wavelet, we approximate a given function by a finite term from the wavelet series. The approximation order is improved if the order of smoothness of the given function is improved, discussed by Cohen (2003), DeVore (1998), and ...

Optimized Deep Learning Framework for Diabetic Retinopathy Based on Systematic Multi‐Stage Transfer Learning and Predictive Risk Stratification

Applied AI Letters, Volume 7, Issue 2, June 2026.
A multi‐stage transfer learning framework systematically optimizes CNN architectures for diabetic retinopathy detection and risk stratification from fundus images. EfficientNetB7 achieves 96% accuracy while a survival‐inspired model generates continuous risk scores aligned with DR severity for clinically meaningful patient risk assessment.

Multi‐Scale Spatio‐Temporal Evidence Learning for Tropical Cyclone Unusual Track Forecasting Over the Western North Pacific

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 3, June 2026.
Abstract Despite significant advances in tropical cyclone track forecasting, unusual tracks remain a major challenge, primarily due to their substantial prediction uncertainty and inadequate representations. In this paper, we present the Tropical Cyclone Unusual Track Forecasting (TCUTF) model, a novel artificial intelligence‐based approach ...

Haar wavelet collocation method for the numerical solution of singular initial value problems

Ain Shams Engineering Journal, 2016
In this paper, numerical solutions of singular initial value problems are obtained by the Haar wavelet collocation method (HWCM). The HWCM is a numerical method for solving integral equations, ordinary and partial differential equations.

THE NAITŌ HYPOSTASIS: NAITŌ KONAN (1866–1934) AND THE JAPANESE IMPERIALIST LEGACY IN THE HISTORIOGRAPHY OF MIDDLE‐PERIOD CHINA (800–1400 CE)

History and Theory, Volume 65, Issue 2, Page 203-236, June 2026.
ABSTRACT In 1955, Hisayuki Miyakawa published an article that sought to introduce American and European scholars to the work of the Japanese Sinologist Naitō Konan (1866–1934). Miyakawa drew particular attention to what he called the “Naitō hypothesis”—that is, Naitō’s argument that China became modern during the Song dynasty (960–1279).

Parenting While Black: Ethnic‐Racial Socialization Among Netherlands‐Based Caribbean and West‐African Heritage Mothers

Journal of Marriage and Family, Volume 88, Issue 3, Page 709-724, June 2026.
ABSTRACT Objective This study explores how and why West African and Caribbean heritage mothers in the Netherlands engage in ethnic‐racial socialization. Background West African and Caribbean communities have long histories in the Netherlands. Even though parents from these communities are tasked with helping children navigate mainstream Dutch culture ...

Comments on "phase-shifting for nonseparable 2-D haar wavelets"

, 2009
In their recent paper, Alnasser and Foroosh derive a wavelet-domain (in-band) method for phase-shifting of 2-D "nonseparable" Haar transform coefficients. Their approach is parametrical to the (a priori known) image translation.
