Automatic POI Matching using an Outlier Detection Based Approach

Points of Interest (POI) are widely used in many applications nowadays mainly due to the increasing amount of related data available online, notably from volunteered geographic information (VGI) sources. Being able to connect these data from different sources is useful for many things like validating, cor- recting and also removing duplicated data in a database. However, there is no standard way to identify the...

Ecological dynamics of Enterobacteriaceae in the human gut microbiome across gl...

Gut bacteria from the Enterobacteriaceae family are a major cause of opportunistic infections worldwide. Given their prevalence among healthy human gut microbiomes, interspecies interactions may play a role in modulating infection resistance. Here we uncover global ecological patterns linked to Enterobacteriaceae colonization and abundance by leveraging a large-scale dataset of 12,238 public human gut metagenom...

Fractional integral operators in variable exponent Stummel spaces

We prove the boundedness of the fractional maximal operator and the Riesz potential operator on variable exponent Stummel spaces. The main results rely on refined uniform weighted inequalities involving special weights with non-standard growth.

Characterization of water status and vegetation cover change in a watershed in ...

The existing water scarcity in the Brazilian semiarid region, associated with anthropic activities, imply in the degradation of the watersheds present in the Caatinga. Therefore, the objective of this study was to characterize water and vegetation cover changes in the Ipanema River Watershed (IRW). IRW is inserted in municipalities that make up the dairy basins of the states of Alagoas and Pernambuco, one of th...

A note on Muckenhoupt weights with nonstandard growth

We provide quantitative results on the inclusion of a family of variable power weights in the Muckenhoupt A1 class, under appropriate conditions on the exponent. We also present an application related to variable exponent Muckenhoupt classes Ap(.).

On fractional operators in Stummel spaces

We give boundedness results for the fractional maximal operator and the Riesz potential operator in the framework of Stummel spaces with variable exponents.

Treatment of Lymphorrhea Associated with an Amputation Stump with Lymphaticoven...

Lower limb lymphorrhea is a condition with a considerable impact on the quality of life. It is usually associated with inguinal lymph node dissection and vascular procedures with femoral exposure. In this case report, we describe a patient who underwent a below-knee amputation and two years later developed lymphorrhea from the stump, preventing adaptation to the prosthesis. Lymphoscintigraphy showed a delayed l...

Maximal operator in variable Stummel spaces

We prove that variable exponent Morrey spaces are closely embedded between variable exponent Stummel spaces. We also study the boundedness of the maximal operator in variable exponent Stummel spaces as well as in vanishing variable exponent Stummel spaces.

Professor Stefan G. Samko research: a decade retrospective

This review article is dedicated to Professor Stefan Samko on the occasion of his 80th birthday. It contains some biographic snippets of S. Samko, as well as a bird’s-eye view on his research during the last decade.
