Subspace based detection in MC-CDMA over dispersive channel [PDF]

open access: yes2000 IEEE International Conference on Personal Wireless Communications. Conference Proceedings (Cat. No.00TH8488), 2002
A new blind MMSE detection for multi-carrier CDMA (MC-CDMA) over intersymbol interference (ISI) channels is proposed. The presence of virtual carriers is exploited to give a subspace based blind channel estimator followed by a linear MMSE equalizer.

ZERO INFLATED NEGATIVE BINOMIAL MODELS IN SMALL AREA ESTIMATION [PDF]

open access: yes, 2008
The problem of over-dispersion in Poisson data is usually solved by introducing prior distributions which lead to negative binomial models. Poisson data sometime is also suffered by excess zero problems, a condition when data contains too many zero or ...

Clinical Insights Into Hypercalcemia of Malignancy in Childhood

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Hypercalcemia of malignancy (HCM) is a rare but life‐threatening metabolic emergency in children that occurs in less than 1% of pediatric cancer cases, with a reported incidence ranging from 0.4% to 1.0% across different studies. While it is observed in 10%–20% of adult malignancies, pediatric HCM remains relatively uncommon.

On the performance of some new ridge parameter estimators in the Poisson-inverse Gaussian ridge regression

open access: yesAlexandria Engineering Journal, 2023
The Poisson Inverse Gaussian Regression model (PIGRM) is used for modeling the count datasets to deal with the issue of over-dispersion. Generally, the maximum likelihood estimator (MLE) is used to estimate the PIGRM estimates.

Variational Bayes Estimation of Discrete-Margined Copula Models with Application to Time Series

open access: yes, 2018
We propose a new variational Bayes estimator for high-dimensional copulas with discrete, or a combination of discrete and continuous, margins. The method is based on a variational approximation to a tractable augmented posterior, and is faster than ...

Survival Outcomes and Complications Among Canadian Children With Retinoblastoma: A Population‐Based Report From CYP‐C

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Purpose Retinoblastoma (RB) is the most common pediatric ocular cancer, yet population‐based data on survival and risk factors remain limited. This study aimed to describe survival in a large national RB cohort and identify predictors of death and complications.

Observations of existence and instability dynamics of near-zero-dispersion temporal Kerr cavity solitons

open access: yesPhysical Review Research, 2021
Dissipative Kerr cavity solitons (CSs) are persisting pulses of light that manifest themselves in driven optical resonators and that have attracted significant attention over the last decade.

NONLINEAR REGRESSION APPLICATIONS IN MODELING OVER-DISPERSION OF BIRD POPULATIONS [PDF]

open access: yesThe Journal of Animal and Plant Sciences, 2020
The aim of this study was to statistically evaluate bird populations in Akdogan Lakes by means of Poisson and negative binomial regression models. The over-dispersion value in Poisson regression was much higher than 1.0 (33.827). In contrast, the value of over-dispersion in the negative binomial regression was very close to 1.0 (1.598).

Personalized Selumetinib Dosing in Pediatric Neurofibromatosis Type 1: Insights From a Pilot Therapeutic Drug Monitoring Study

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Objective To evaluate selumetinib exposure using therapeutic drug monitoring (TDM) in pediatric patients with neurofibromatosis type 1 (NF1) and plexiform neurofibromas (PN), assess interpatient pharmacokinetic variability, and explore the relationship between drug exposure, clinical response, and adverse effects.

Composite quantile regression approach to batch effect correction in microbiome data

open access: yesFrontiers in Microbiology
BackgroundBatch effects refer to data variations that arise from non-biological factors such as experimental conditions, equipment, and external factors.
