Small U‐Net for Fast and Reliable Segmentation in Imaging Flow Cytometry

open access: yesCytometry Part A, EarlyView.
A schematic illustrating the key components and workflow for training a U‐Net model with a customizable architecture. The process begins with data curation and annotation using the integrated GUI, followed by model configuration and training, and concludes with deployment optimized for performance metrics and processing speed.

On Convex Hull of Orthogonal Scalar Spectral Functions of a Carleman Operator

open access: yesBoletim da Sociedade Paranaense de Matemática, 2008
In this paper we describe the closed convex hull of orthogonal resolvents of an abstract symmetric operator of defect indices (1; 1), then we study the convex hull of orthogonal spectral functions of a Carleman operator in the Hilbert space L^2(X;mu).

A plane 1.88-spanner for points in convex position

open access: yesJournal of Computational Geometry, 2016
Let $S$ be a set of $n$ points in the plane that is in convex position. For a real number $t>1$, we say that a point $p$ in $S$ is $t$-good if for every point $q$ of $S$, the shortest-path distance between $p$ and $q$ along the boundary of the convex ...

A Content-based Image Retrieval System Based On Convex Hull Geometry

open access: yes, 2015
Developments in data storage technologies and image acquisition methods have led to the assemblage of large data banks. Management of these large chunks of data in an efficient manner is a challenge.

A test of the abundant‐center hypothesis for stream fishes

open access: yesEcography, EarlyView.
The abundant‐center hypothesis (ACH) provides a conceptual model for predicting range‐wide distributions of species abundance, suggesting that abundance peaks in the center of the geographic range and declines towards range edges. Empirical studies testing the ACH and its subsequent derivations predominantly occurred in terrestrial systems and reported
