Solution of certain weakly singular integral equations
, 2006 Direct function theoretic methods are developed to handle two weakly singular integral equations with their kernels having logarithmic singularity. The present methods avoid the occurrence of higher-order (or strong) singularities, like the Cauchy type ...

Lost in aggregation? On the importance of local food price data for food poverty estimates
American Journal of Agricultural Economics, EarlyView.Abstract This paper explores within‐country variations in food price dynamics and food poverty estimates by employing local market price data and national consumer price index (CPI) data. Our results show that national CPI data may be useful for approximating national trends but they fail to detect and identify spatial variations in local trends, which

Long‐Range Interactions in Topological Superconducting Systems: A Mini Review
Advanced Physics Research, EarlyView.Long‐range interacting quantum systems are surveyed in this review, with an emphasis on the long‐range topological superconductor and its variants. Long‐range interactions decaying in a power‐law manner can lead to exotic phenomena that finds no analogue in short‐range regimes.

Brain Health, EarlyView.ABSTRACT Assessing and quantifying brain health remains a pressing challenge, despite its importance for overall well‐being. Traditional methods that focus on isolated brain measures often fail to capture the multifaceted nature of brain health and may miss early signs of dysfunction.

Nonlinear singular integral inequalities for functions in two and
Journal of Inequalities and Applications, 2000 In this paper nonlinear integral inequalities with weakly singular kernels for functions in two and independent variables are solved. The obtained results are related to the well known Gronwall–Bihari and Henry inequalities for functions in one ...
