Evaluation of expressions and programs in a computer al gebra system is central to every system but inevitably fails to provide complete satisfaction Here we explain the con icting requirements describe some solutions from current systems and propose alternatives that might be preferable sometimes We give examples primarily from Axiom Mac syma Maple Mathematica with passing mention of a few oth...

Computer science is a diverse, exciting, and rapidly expanding discipline. Inevitably the research community pulls itself in different directions, sometimes with the result that visionary research may be under-valued. This paper explores systemic issues of general applicability with the aim of understanding and hence valuing the diversity.

E-learning will not inevitably cause a revolution of the traditional university. On the contrary, it is not clear whether multimedia and network technology will find its place in the university to the profit of the students. We discuss various methods and techniques and propose best practices, which can succeed under the specific conditions of a traditional university.

Computing Science is a diverse, exciting, and expanding discipline. Inevitably the Computing Science community pulls itself in different directions, sometimes with the result that some worthwhile research is under-valued. This paper explores systemic issues of general applicability, and makes some constructive suggestions.

Uterine fibroids may be encountered with pregnancy and many obstetricians will inevitably confront the dilemma of how best to manage fibroids causing complications in a gravid uterus. We describe two cases of unavoidable caesarean myomectomy and myomectomy performed for the management of complications during pregnancy.

Cells in exposed positions are subject to injury and therefore need membrane repair mechanisms. Ca(2+) entry inevitably follows membrane rupture and recent studies indicate that this elicits repair via Ca(2+)-activated exocytosis of lysosomes, regulated by lysosomal synaptotagmin VII.

Spatial statistical analyses inevitably are affected by positional errors embedded in georeferenced data. Positional errors further propagate when observations need to be geographically aggregated. This data accuracy issue often results in unreliable statistical conclusion about attribute variables in spatial statistical modeling. This paper investigates how positional errors propagate to varia...

Diabetes mellitus (DM) is a common disease worldwide and a growing public health burden. The number of people with diabetes is increasing due to population growth, aging, urbanization, and increasing prevalence of obesity and physical inactivity. Diabetes is known to cause multiple medical, psychological, and sexual dysfunctions. Increased prevalence of diabetes will inevitably result in increa...

Grammars for programming languages are traditionally specified statically. They are hard to compose and reuse due to ambiguities that inevitably arise. PetitParser combines ideas from scannerless parsing, parser combinators, parsing expression grammars and packrat parsers to model grammars and parsers as objects that can be reconfigured dynamically. Through examples and benchmarks we demonstrat...

The partial pressure of NH3 gas estimated by Raman spectroscopy indicates that approximately 0.1% NH3 inevitably contaminates the H2 desorbed from a hydrogen storage material composed of LiH and LiNH2 at any temperature up to 400 degrees C in a closed system.
