On the asymptotics of orthogonal polynomials on the curve with a denumerable mass points
Journal of Numerical Analysis and Approximation Theory, 2007 We investigate the asymptotic behavior of orthogonal polynomials with respect to a measure of the type \(\sigma =\alpha +\gamma \), where \(\alpha \) is a measure concentrated on a rectifiable Jordan curve and \(\gamma \) is an infinite discrete measure.

A notion of continuity in discrete spaces and applications
Applied General Topology, 2013 We propose a notion of continuous path for locally finite metric spaces, taking inspiration from the recent development of A-theory for locally finite connected graphs.

Sustainable Productivity Growth in Agriculture: The Role of Shifts in R&D Investments and Technology
Applied Economic Perspectives and Policy, EarlyView.ABSTRACT The objective of the paper is to evaluate the long‐term prospects of sustainable productivity growth linked to plausible assumptions on public agricultural R&D investments as the key productivity driver. Second, it investigates the role of changing R&D focus from yield maximization to input saving technologies (fertilizers and pesticides). The

LABELING OF N-DIMENSIONAL IMAGES WITH CHOOSABLE ADJACENCY OF THE PIXELS
Image Analysis and Stereology, 2011 The labeling of discretized image data is one of the most essential operations in digital image processing. The notions of an adjacency system of pixels and the complementarity of two such systems are crucial to guarantee consistency of any labeling ...

Galactic rotation dynamics in a new $$f({\mathcal {R}})$$ f ( R ) gravity model
European Physical Journal C: Particles and Fields, 2023 We propose to test the viability of the recently introduced $$f(\mathcal {R})$$ f ( R ) gravity model in the galactic scales. For this purpose we consider test particles moving in stable circular orbits around the galactic center.

Cost‐Benefit Analysis of the European Union Carbon Border Adjustment Mechanism in Fertilizer Trade
Agribusiness, EarlyView.ABSTRACT The carbon border adjustment mechanism (CBAM), launching 2026, will charge EU importers for embedded carbon emissions, aiming to reduce emissions but raising import costs. Shifts in demand following implementation may reduce carbon emissions, but importers will bear the cost of increased prices.

A converse to the Jordan curve theorem for digital curves
Information and Control, 1975 It is shown that a subset S of a digital picture is a simple closed curve if and only if its complement S¯ has exactly two components, and every point of S is adjacent to both of these components.

American Journal of Agricultural Economics, EarlyView.Abstract Large‐scale land reforms constitute a substantial redistribution of wealth and reallocation of agricultural land, which is a major form of asset and production input in developing countries. While land redistribution (from the rich to the poor) remains a highly controversial issue, extensive evidence on its effect is limited.

Shotgun Metagenomic Profiling of the Gut Virome in Prodromal and Confirmed Parkinson's Disease
Annals of Neurology, EarlyView.We conducted a nested case‐control study within the Nurses’ Health Study and the Health Professionals Follow‐up Study to examine the role of the gut virome (GV) in Parkinson's disease (PD). We applied a novel metagenomic virome profiling approach, Bioinformatic Application for Quantification and Labeling of Viral taxonomy (BAQLaVa), to prospectively ...
