Evaluation of ionizing radiation as a risk factor for the incidence of breast cancer: long-term analysis after the cesium-137 accident in Goiânia, Brazil. An ecological study

open access: yesSão Paulo Medical Journal, 2020
BACKGROUND: The largest radiological accident to occur in any urban area happened in Goiânia, Brazil, in 1987. OBJECTIVE: To evaluate the association between breast cancer incidence and ionizing radiation levels. DESIGN AND SETTING: Ecological study

PACKING DIMENSIONS OF GENERALIZED RANDOM MORAN SETS [PDF]

open access: yesJournal of the Korean Mathematical Society, 2014
We consider random fractal sets with random recursive con- structions in which the contracting vectors have different distributions at different stages. We prove that the random fractal associated with such construction has a constant packing dimension almost surely and give an explicit formula to determine it.

Generalised Cantor sets and the dimension of products [PDF]

open access: yes, 2015
In this paper we consider the relationship between the Assouad and box-counting dimension and how both behave under the operation of taking products. We introduce the notion of ‘equi-homogeneity’ of a set, which requires a uniformity in the cardinality ...

Prediction of Gas Chromatography-Mass Spectrometry Retention Times of Pesticide Residues by Chemometrics Methods

open access: yesJournal of Chemistry, 2013
A quantitative structure-retention relationships (QSRRs) method is employed to predict the retention time of 300 pesticide residues in animal tissues separated by gas chromatography-mass spectroscopy (GC-MS).

A comparison of plotless density estimators using Monte Carlo simulation on totally enumerated field data sets

open access: yesBMC Ecology, 2008
Background Plotless density estimators are those that are based on distance measures rather than counts per unit area (quadrats or plots) to estimate the density of some usually stationary event, e.g. burrow openings, damage to plant stems, etc.

Local dimensions in Moran constructions

open access: yes, 2015
We study the dimensional properties of Moran sets and Moran measures in doubling metric spaces. In particular, we consider local dimensions and $L^q$-dimensions.

Weak separation condition, Assouad dimension, and Furstenberg homogeneity

open access: yes, 2015
We consider dimensional properties of limit sets of Moran constructions satisfying the finite clustering property. Just to name a few, such limit sets include self-conformal sets satisfying the weak separation condition and certain sub-self-affine sets ...

Translating Video Recordings of Mobile App Usages into Replayable Scenarios

open access: yes, 2020
Screen recordings of mobile applications are easy to obtain and capture a wealth of information pertinent to software developers (e.g., bugs or feature requests), making them a popular mechanism for crowdsourced app feedback.
