Honu is a new language that contains a system for extending its syntax with an interface built on concrete syntax. Honu combines an existing hygienic macro system with a novel use of a precedence parser to achieve a syntax that is algol-like while maintaining the power of s-expression based macros. We demonstrate how to build the parser and connect it to the underlying macro system.

in recent year, the evolutionary structural optimization (eso) method, has been applied as an effective tool for structures design. the concept of eso method is to use the finite element  results in each iteration of process and removal of inefficient material based on these results. in this method there are several experimental parameters such as rejection rate and evolutionary rate that are e...

Many animals have individual and social mechanisms for combating pathogens. Animals may exhibit short-term physiological tradeoffs between social and individual immunity because the latter is often energetically costly. Genetic tradeoffs between these two traits can also occur if mutations that enhance social immunity diminish individual immunity, or vice versa. Physiological tradeoffs between ...

Within the multi-disciplinary CARMA (Campylobacter Risk Management and Assessment) project it was decided to focus on evaluation of interventions in the chicken meat chain. To assess the effect of control measures on the farm we developed a model on Campylobacter transmission in Dutch broilers and broiler flocks, resulting in an estimate of the Campylobacter prevalence in broilers for slaughter...

The enormous role of water in the life all living beings, including humans, is due to fact that it a universal solvent for huge number chemicals. Water was one first compounds attract attention scientists, yet its study still incomplete. basis and raw material technologies industries. used technological process food industry must comply with hygienic requirements and, addition cleaning, reducin...

Existing source-code-generating tools such as Lex and Yacc suffer from practical inconveniences because they use disembodied code to implement actions. To prevent this problem, such tools could generate closed functors that are then instantiated by the programmer with appropriate action code. This results in all code being type checked in its appropriate context, and it assists the type checker...

This article examines the role of narratives war in early twentieth-century and twenty-first-century U.S.-American health campaigns by studying several public posters with methods visual analysis. It offers two complementary approaches to theorize semantics war. First, cognitivist terms, contribution posits that conceptual domain provides a narrative framework for rendering an invisible danger ...

Division of labor in social insects has made the evolution of collective traits possible that cannot be achieved by individuals alone. Differences in behavioral responses produce variation in engagement in behavioral tasks, which as a consequence, generates a division of labor. We still have little understanding of the genetic components influencing these behaviors, although several candidate g...
