OBJECTIVE On the basis of California's experience implementing a pilot tandem mass spectrometry (MS/MS) screening program, an economic evaluation was conducted to determine the economic benefits and costs of a statewide MS/MS screening program. METHODS Cost-effectiveness, benefit/cost, and cost-utility analyses were conducted with a base-case set of assumptions. The base-case assumptions were...

Some classes of increment martingales, and the corresponding localized classes, are studied. An increment martingale is indexed by R and its increment processes are martingales. We focus primarily on the behaviour as time goes to −∞ in relation to the quadratic variation or the predictable quadratic variation, and we relate the limiting behaviour to the martingale property. Finally, integration...

The success or failure of any project is very largely depends on its SDLC (Software Development Life Cycle) model. In this paper a new software development lifecycle model is designed using incremental spiral lifecycle model with software reuse concept. The proposed model is designed in such a way that it combines the capability of spiral and incremental model with reusability. The software dev...

A novel and robust statistic as a similarity measure for robust image registration is proposed. The statistic is named as Increment Sign Correlation because it is based on average evaluation of incremental tendency of brightness in adjacent pixels. It is formalized to be a binary distribution or a Gaussian distribution for a large image size through statistical analysis and modeling. By utilizi...

Empirical evidence from both utility and psychophysical experiments suggests that people respond quite differently—perhaps discontinuously—to stimulus pairs when one consequence or signal is set to ‘zero.’ Such stimuli are called unitary. The author’s earlier theories assumed otherwise. In particular, the key property of segregation relating gambles and joint receipts (or presentations) involve...

BACKGROUND Family-based behavioral weight control treatment involves the parent in the modification of child and parent eating and activity change. OBJECTIVE To assess if parent standardized body mass index (z-BMI) change predicts child z-BMI change. DESIGN Secondary data analysis based on parent and child z-BMI changes from 3 family-based, randomized, controlled weight control studies. Hie...

BACKGROUND South Africa has the highest prevalence of overweight/obesity in Sub-Saharan Africa. Assessing the effect of modifiable factors such as early infant feeding on growth velocity and overweight/obesity is therefore important. This paper aimed to assess the effect of infant feeding in the transitional period (12 weeks) on 12-24 week growth velocity amongst HIV unexposed children using WH...
