Needed Computations Shortcutting Needed Steps

We define a compilation scheme for a constructor-based strongly-sequential graph rewriting system which shortcuts some needed steps. The object code, what the compiler produces on input the rewriting system, is another constructor-based graph rewriting system that is normalizing for the original system when using an innermost strategy. Hence, the object code can be easily implemented by eager f...

The Status of Cross Section Measurements for Neutron-induced Reactions Needed for Cosmic Ray

Introduction: Cosmic ray interactions with lunar rocks and meteorites produce small amounts of radio-nuclides and stable isotopes. Advances in Accelerator Mass Spectrometry (AMS) allow production rates to be measured routinely in well-documented lunar rocks and meteorites. These measurements are analyzed using theoretical models to learn about the object itself and the history of the cosmic ray...

Fetal Reactions

By the use of ultrasound, chemical analysis and histologic techniques, the knowledge of embryo and fetal growth and developments is increasing steadily.  It has been demonstrated that the fetus can respond to sound, bright light and touch. Accordingly, works on fetal responses to external stimuli during the third trimester may ultimately lead to improve­ments in the techniques of antepartum fe...
