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.

Fault Strike Detection Using Satellite Gravity Data Decomposition by Discrete Wavelets: A Case Study from Iran [PDF]
Estimating the gravity anomaly causative bodies boundary can facilitate the gravity field interpretation. In this paper, 2D discrete wavelet transform (DWT) is employed as a method to delineate the boundary of the gravity anomaly sources.

The Haar wavelet characterization of weighted Herz spaces and greediness of the Haar wavelet basis
The authors study the class of dyadic \(A_p\)-weights in connection with dyadic maximal operators (where in both cases on considers dyadic cubes only) and show that one obtains results corresponding to the ones one gets for the usual \(A_p\)-weights and maximal operators.

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 ...

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).

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 ...

ABSTRACT For many occupations, the toll of work‐related stressors on job satisfaction may be mitigated by social and emotional support. However, social support may be different for clergy, considering their unique work environment. Using data from the Clergy Health Initiative Longitudinal Survey, this study examines the relationship between different ...

Sparse orthogonal matrices and the Haar wavelet
The authors discuss the sparsity of orthogonal matrices which have a column of nonzero entries. It is shown that the minimun number of nonzero entries in such a matrix of size \(m\times m\) is \[ (\lfloor m\rfloor +3)m-2^{\lfloor m\rfloor+1}. \] This is optimal, as the paper characterizes the matrices which achieve this number.
