Guidelines for Pediatric Radiotherapy Simulation: A Report From the Children's Oncology Group Radiation Oncology Discipline

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Pediatric radiation therapy presents unique challenges compared to adult treatments, including those of immobilization, potential need for sedation, and the critical importance of accurate, reproducible positioning. Additionally, heightened attention to imaging doses is necessary to minimize long‐term toxicity in survivors.

Inferences for the Change-Point of The Exponentiated Weibull Hazard Function

Revstat Statistical Journal, 2012
In many applications of lifetime data analysis, it is important to perform inferences about the change-point of the hazard function. The change-point could be a maximum for unimodal hazard functions or a minimum for bathtub forms of hazard functions and

Oscillation and hazard functions

Mathematical and Computer Modelling, 2000
In the medical data analysis, the shapes of hazard functions are very important for the survival analysis. The simple dimensional hazard function is given by r(t) = f(t)(1 - F(t)), 0 @? F(t) < 1, where f(t) is a probability density function with its distribution function F(t).

Improved Early Referral in Long‐Term Survivor Care With Institutional Standardized Practice Among Childhood Leukemia Survivors#

Pediatric Blood &Cancer, EarlyView.
ABSTRACT In 2018, the Texas Children's Cancer and Hematology Center Leukemia Program implemented a practice standard to support the transition from treatment to survivorship that includes shared, alternating care between leukemia and survivorship clinicians and a reminder to refer survivors to the long‐term survivor clinic (LTSC) 2 years after ...

Detecting Clinical Risk Shift Through log–logistic Hazard Change-Point Model

Mathematics
The change–point problem is about identifying when a pattern or trend shifts in time–ordered data. In survival analysis, change–point detection focuses on identifying alterations in the distribution of time–to–event data, which may be subject to ...

The Use of Hazard Models for the Analysis of Income Inequalities in Poland

Folia Oeconomica Stetinensia, 2018
The aim of the paper is to examine the income inequalities of men and women in Poland. We estimate conditional cumulative distribution functions for incomes in both groups of people using a flexible hazard-function based estimator in the presence of ...

How can we learn what attention is? Response gating via multiple direct routes kept in check by inhibitory control processes

Open Psychology, 2020
To explore the time course of space- and object-based attentional selection processes I analysed the shapes of the response time (RT) and accuracy distributions of left/right arrow identification responses in the two-rectangle paradigm.

Statistical Inference of Generalized Time- Dependent Logistic Hazard Model [PDF]

The Egyptian Statistical Journal, 2018
In this paper ,we extend the generalized time-dependtent logistic hazard model (GTDL)proposed by Mackenzie (1996) by using  the hazard function of weibull distribution instead  of  the   baseline hazard function  as no form was assumed in this  model ...

Personalized Zebrafish Models for Fusion‐Positive Pediatric Sarcomas

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Clinical sequencing efforts have revolutionized our approaches to categorizing pediatric cancers in real time. This has dramatically improved our ability to profile pediatric tumors, identify actionable vulnerabilities, and influence clinical care.

Profit Optimalization in Operation Systems

Polish Maritime Research, 2016
The aim of this study is to analyse the effect of reducing the number of secondary damage to profit from the work of a technical object. Considering the criterion function that describes the average profit from the work of a technical object in the ...
