Pointer errors are stumbling blocks for student and veteran programmers alike. Although languages such as Java use references to protect programmers from pointer pitfalls, the use of garbage collection dictates that languages like C++ will still be used for real-time mission-critical applications. Pointers will stay in the classroom as long as they're used in industry, so as educators, we must find better ways to teach them. This paper presents checked pointers, a simple wrapper for C++doi:10.1145/331795.331884 fatcat:sbbdcx6cwrdnxb7ad7kmqaecie

The syntax of checked pointers is highly faithful to raw C++ pointers, but provides run-time error detection and debugging information. After debugging, changing one #include is all that is required to substitute a nonchecking implementation that is as fast as raw C++.

The Oz project at Carnegie Mellon is developing technology for dramatic virtual worlds. One requirement of such worlds is the presence of broad, though perhaps shallow, agents. To support our needs, we are developing an agent architecture that provides goals and goal directed reactive behavior, emotional state and its e ects on behavior, some natural language abilities (especially pragmatics based language generation), and some memory and inference abilities. We are limiting each of thesedoi:10.1145/122344.122350 fatcat:tpw7hdsw6rhbjhe7wj6juvt76y

This review examines the DNA polymerases, a class of enzymes that has been an essential tool for molecular biology research. Several families of DNA polymerases have been defined based on amino acid sequence comparisons, and new enzymes are continually being discovered, driving the expansion of the current classifications. Structural similarities among the enzymes are examined, as well as the functions of the various subunits and enzyme domains. The natural variety of polymerase activities hasdoi:10.2144/01312rv01 pmid:11515374 fatcat:ejz7mm3rcbd2bp3dwpidzodjhu

In addition, enhancements to DNA polymerases by genetic engineering will be described, such as enzymes specifically designed for DNA sequencing by improving the incorporation of dideoxynucleotide terminators. Reverse transcription, the ability to use RNA as a template for DNA synthesis, is described for the application of making cDNA. We believe that new and unanticipated applications will emerge as new polymerases and mutated polymerases are created and characterized.

An inexpensive, rapid method for measuring the rheological properties of yield stress fluids is described and tested. The method uses an auger that does not rotate during measurements, and avoids material and instrument-related difficulties, for example, wall slip and the presence of large particles, associated with yield stress fluids. The method can be used for many types of yield stress fluids, including concentrated lignocellulosic biomass. Sample preparation prior to measurement isdoi:10.1002/aic.14329 fatcat:53rlrugh7fgebjvwovnwuwf5ki

Lycoperine A was synthesized through a highly convergent route in which a double alkylation of 2,6-dicyano-N-benzylpiperidine with the octahydroquinoline moiety gave the lycoperine skeleton. The octahydroquinoline was prepared by a desymmetrization reaction of 5methylcyclohexane-1,3-dione. Hydrolysis, reductive amination and cyclization gave lycoperine A in 13 steps and 3% overall yield. The absolute configuration of lycoperine A was assigned as 6R, 6′R, 8R, 8′R, 13S, 17R.doi:10.1021/ol902389e pmid:19947619 pmcid:PMC2913050 fatcat:vsqw3mncz5d55lfgouqglnm4mq
