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

Nonlinear singular integral inequalities for functions in two and independent variables

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 ...

Error analysis of arbitrarily high-order stepping schemes for fractional integro-differential equations with weakly singular kernels

Nonlinear Engineering
We propose high-order computational schemes for solving nonlinear fractional integro-differential equations (FIDEs) that are commonly used to model systems with memory or long-term behavior.

Protective Effect of Phytic Acid in Cardiovascular Diseases: A Systematic Review

ChemFoodChem, EarlyView.
ABSTRACT Cardiovascular diseases (CVDs) are a cluster of ailments that impact the heart and blood vessels and are a primary public health problem of mortality on a global scale. Phytic acid, a dietary constituent frequently present in foods like seeds, has been linked to many pharmacological attributes, including anti‐cancer, antioxidant, anti ...

Stochastic Gradient Descent in High Dimensions for Multi‐Spiked Tensor PCA

Communications on Pure and Applied Mathematics, EarlyView.
ABSTRACT We study the high‐dimensional dynamics of online stochastic gradient descent (SGD) for the multi‐spiked tensor model. This multi‐index model arises from the tensor principal component analysis (PCA) problem with multiple spikes, where the goal is to estimate the unknown signal vectors within the N$N$‐dimensional unit sphere through maximum ...
