Efficient Stratified Sampling Graphing Method for Mass Data

Data Science Journal, 2019
Sequentially linking data during polyline graphing of mass data (millions of points or more) generally results in poor graphing efficiency. Numerous curves are buried behind each pixel and cannot be displayed due to resolution limits of the width of the ...

Spectral analysis of stratified sampling: a means to perform efficient multiband spectrum sensing

, 2012
This paper introduces a multiband spectrum sensing technique that utilizes nonuniform stratified sampling. Capitalising on the ability of the sampling scheme to suppress aliasing, the proposed method accomplishes the sensing task using sampling rates ...

Evaluation of Three Sampling Methods to Monitor Outcomes of Antiretroviral Treatment Programmes in Low- and Middle-Income Countries. [PDF]

, 2010
BACKGROUND: Retention of patients on antiretroviral therapy (ART) over time is a proxy for quality of care and an outcome indicator to monitor ART programs. Using existing databases (Antiretroviral in Lower Income Countries of the International Databases

European Standard Clinical Practice Guideline and EXPeRT Recommendations for the Diagnosis and Management of Gastroenteropancreatic Neuroendocrine Neoplasms in Children and Adolescents

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Pediatric gastroenteropancreatic neuroendocrine neoplasms (GEP‐NENs) are extremely rare and clinically heterogeneous. Management has largely been extrapolated from adult practice. This European Standard Clinical Practice Guideline (ESCP), developed by the EXPeRT network in collaboration with adult NEN experts, provides (adult) evidence ...

Depth-stratified soil sampling for assessing nematode communities

Semina: Ciências Agrárias, 2016
This study assessed the importance of stratified soil sampling on the detection (and therefore the distribution) of nematode communities and the differentiation of ecosystems by collecting stratified soil samples at intervals of 10 cm and non-stratified ...

Assessing Antithetic Sampling for Approximating Shapley, Banzhaf, and Owen Values

AppliedMath, 2023
Computing Shapley values for large cooperative games is an NP-hard problem. For practical applications, stochastic approximation via permutation sampling is widely used. In the context of machine learning applications of the Shapley value, the concept of

Solid Pseudopapillary Neoplasm of the Pancreas in Children and Adolescents: Expert Recommendations

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Solid pseudopapillary neoplasm of the pancreas (SPN) is a rare low‐grade malignant exocrine pancreatic tumor, mostly discovered during the second decade of life in females, with a very good prognosis, provided microscopically complete surgical excision is achieved.
