The dimension of an amoeba [PDF]

open access: yesBulletin of the London Mathematical Society, 2019
Answering a question by Nisse and Sottile, we derive a formula for the dimension of the amoeba of an irreducible algebraic variety.Comment: 8 pages, several small improvements, final ...

Tracking tripartite interaction dynamics: isolation, integration, and influence of bacteriophages in the Paraburkholderia-Dictyostelium discoideum symbiosis system [PDF]

open access: yesFrontiers in Microbiology
IntroductionBacteriophages influence interactions between bacterial symbionts and their hosts by exerting parasitic pressure on symbiont populations and facilitating bacterial evolution through selection, gene exchange, and prophage integration.

Intersections of Amoebas [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2020
Amoebas are projections of complex algebraic varieties in the algebraic torus under a Log-absolute value map, which have connections to various mathematical subjects. While amoebas of hypersurfaces have been inten- sively studied during the last years, the non-hypersurface case is barely understood so far.

A distributed file service based on optimistic concurrency control [PDF]

open access: yes, 1985
The design of a layered file service for the Amoeba Distributed System is discussed, on top of which various applications can easily be intplemented. The bottom layer is formed by the Amoeba Block Services, responsible for implementing stable storage and

Acanthamoeba polyphaga-enhanced growth of Mycobacterium smegmatis. [PDF]

open access: yesPLoS ONE, 2012
BACKGROUND: Mycobacterium smegmatis is a rapidly-growing mycobacterium causing rare opportunistic infections in human patients. It is present in soil and water environments where free-living amoeba also reside, but data regarding M.

Development of a Machine Learning-Based Cysticidal Assay and Identification of an Amebicidal and Cysticidal Marine Microbial Metabolite against Acanthamoeba

open access: yesMicrobiology Spectrum, 2022
Traditional cysticidal assays for Acanthamoeba species revolve around treating cysts with compounds and manually observing the culture for evidence of excystation. This method is time-consuming, labor-intensive, and low throughput. We adapted and trained

AMOEBAS AND INSTANTONS [PDF]

open access: yesInternational Journal of Modern Physics A, 2007
We study a statistical model of random plane partitions. The statistical model has interpretations as five-dimensional [Formula: see text] supersymmetric SU (N) Yang–Mills on ℝ4× S1and as Kähler gravity on local SU (N) geometry. At the thermodynamic limit a typical plane partition called the limit shape dominates in the statistical model.

Dimers and amoebae [PDF]

open access: yesAnnals of Mathematics, 2006
We study random surfaces which arise as height functions of random perfect matchings (a.k.a. dimer configurations) on an weighted, bipartite, doubly periodic graph G embedded in the plane. We derive explicit formulas for the surface tension and local Gibbs measure probabilities of these models. The answers involve a certain plane algebraic curve, which

Neurons on amoebae

open access: yesJournal of Symbolic Computation, 2023
We apply methods of machine-learning, such as neural networks, manifold learning and image processing, in order to study 2-dimensional amoebae in algebraic geometry and string theory. With the help of embedding manifold projection, we recover complicated conditions obtained from so-called lopsidedness.

Clinical Manifestations and Etiology of Liver Abscess in Children in Tertiary Care Hospital [PDF]

open access: yesLiaquat National Journal of Primary Care, 2023
Background: The liver is a major metabolic organ with a dual blood supply, hence vulnerable to infection. The liver abscess (LA) is a space-occupying lesion in the liver parenchyma filled with pus caused by bacteria, parasites, or fungus. Objective: To
