Pacific Journal of Mathematics, 2022 An amoeba is the image of a subvariety of an algebraic torus under the logarithmic moment map. We consider some qualitative aspects of amoebas, establishing some results and posing problems for further study. These problems include determining the dimension of an amoeba, describing an amoeba as a semi-algebraic set, and identifying varieties whose ...

Microbiology Spectrum, 2022 The engulfment of Legionella pneumophila by free-living amoebae (FLA) in engineered water systems (EWS) enhances L. pneumophila persistence and provides a vehicle for rapid replication and increased public health risk.

Clinical Characteristic of Bloody Diarrhea in Under- Five Pediatric Inpatients
Archives of Pediatric Gastroenterology, Hepatology, and Nutrition, 2022 Background: Diarrhea is the most common cause of death in under-five children. Bloody diarrhea comprises around 10% of all cases of diarrhea and may lead to severe complications until death.

Frontiers in Microbiology, 2023 Free-living amoebae are described as potential reservoirs for pathogenic bacteria in the environment. It has been hypothesized that this might be the case for Mycobacterium avium subsp. paratuberculosis, the bacterium responsible for paratuberculosis. In

The ‘Amoeboid Predator-Fungal Animal Virulence’ Hypothesis
Journal of Fungi, 2019 The observation that some aspects of amoeba-fungal interactions resemble animal phagocytic cell-fungal interactions, together with the finding that amoeba passage can enhance the virulence of some pathogenic fungi, has stimulated interest in the amoeba ...

Analysis of Amoeba Active Contours [PDF]
, 2014 Subject of this paper is the theoretical analysis of structure-adaptive median filter algorithms that approximate curvature-based PDEs for image filtering and segmentation. These so-called morphological amoeba filters are based on a concept introduced by

Amoeba-Resisting Bacteria and Ventilator-Associated Pneumonia
Emerging Infectious Diseases, 2003 To evaluate the role of amoeba-associated bacteria as agents of ventilator-associated pneumonia (VAP), we tested the water from an intensive care unit (ICU) every week for 6 months for such bacteria isolates; serum samples and bronchoalveolar lavage ...

A Nullstellensatz for amoebas [PDF]
Duke Mathematical Journal, 2008 The amoeba of an affine algebraic variety V in (C^*)^r is the image of V under the map (z_1, ..., z_r) -> (log|z_1|, ..., log|z_r|). We give a characterisation of the amoeba based on the triangle inequality, which we call testing for lopsidedness.
