A Graph-based Framework for Multiple Change-point Detection [PDF]

open access: yes, 2023
We study the problem of multiple change-point detection in high-dimensional data and non-Euclidean data with graph-based statistics. With the emergence of more complex data with multiple change-points, traditional change-point detection methods for low ...

The Origins of the Multiple-Point Statistics (MPS) Algorithm [PDF]

open access: yes, 2018
First proposed in the early 1990s, the geostatistical algorithm known as multiple-point statistics (MPS) now enjoys widespread use, particularly in petroleum studies. It has become part of the toolkit that new practitioners are trained to use in several oil companies; it has been incorporated into commercial software; and research programs in many ...

Conditioning multiple-point statistics simulations to block data [PDF]

open access: yesSpatial Statistics, 2016
Multiple-points statistics (MPS) allows to generate random fields reproducing spatial statistics derived from a training image. MPS methods consist in borrowing patterns from the training set. Therefore, the simulation domain is assumed to be at the same resolution as the conceptual model, although geometrical deformations can be handled by such ...

Deep Sequencing of FLT3‐ITD Enables Response Evaluation and Post‐Treatment Monitoring in Childhood AML: An Exploratory Study

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background An internal tandem duplication in the gene encoding Fms‐like tyrosine kinase 3 (FLT3‐ITD) is associated with high relapse risk and poor prognosis in acute myeloid leukemia (AML) and plays a crucial role in treatment decisions. Measurable residual disease (MRD) analysis of FLT3‐ITD during and after treatment has shown prognostic ...

Fracture density reconstruction using direct sampling multiple-point statistics and extreme value theory

open access: yesApplied Computing and Geosciences
The aim of this work is to present a methodology for the reconstruction of missing fracture density within highly fractured intervals, which can represent preferential fluid flow pathways. The lack of record can be very common due to the intense presence

Restoration for Intensity Nonuniformities with Discontinuities in Whole-Body MRI

open access: yesSignals, 2023
The reconstruction in MRI assumes a uniform radio-frequency field. However, this is violated due to coil field nonuniformity and sensitivity variations.

Time Toxicity in Wilms Tumor: Quantifying the Burden of Healthcare Interaction in the First Year After Diagnosis

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Wilms tumor (WT) treatment imposes a significant time burden on patients and their families. Time toxicity is a patient‐centered metric that quantifies the burden of healthcare interaction. We sought to define time toxicity in the first year after diagnosis of WT and hypothesized that it would increase as tumor stage and treatment ...

Alternative geostatistics tools applied to Morroa aquifer modeling (Sucre-Colombia)

open access: yesRevista Facultad de Ingeniería Universidad de Antioquia, 2013
In this paper, stochastic simulations and some multiple-point geostatistical principles are developed using a comparative methodology consisting of two phases.

onlineBcp: An R package for online change point detection using a Bayesian approach

open access: yesSoftwareX, 2022
Change point analysis has been useful for practical data analytics. In this paper, we provide a new R package, onlineBcp, based on an online Bayesian change point detection algorithm.

Heterogeneity in the Global Practice of Central Nervous System Staging in Pediatric Acute Lymphoblastic Leukemia

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Central nervous system (CNS) involvement in childhood acute lymphoblastic leukemia (ALL) is assessed by cell counting and cytomorphology from cerebrospinal fluid (CSF) and is used for treatment stratification worldwide. The ratio of “CNS2” patients in clinical trials ranges from 3% to 40%, with unclear prognostic significance ...
