spo16 mutants in yeast were reported to have reduced map lengths, a high frequency of nondisjunction in the first meiotic division, and essentially unchanged coefficients of coincidence. Were all crossing over in yeast subject to interference, such data would suggest that the "designation" of recombination events to become crossovers is separable from the "implementation" of that crossing over....

Electronic order book trading has evolved in being recognized as the best-practice for trading small and mid-sized orders. Yet, this mechanism does not properly address the needs of large-sized orders which tend to execute off order book in over-the-counter markets. Order book trading provides for public price discovery but not for quantity discovery. Off book executions generally fragment the ...

Crossover clinical trials can provide substantial benefits by eliminating inter-patient variation from treatment comparisons and by allowing multiple observations of each patient. They are particularly useful when sample sizes are necessarily small. These advantages proved particularly valuable in an assessment of clot prevention in children undergoing haemodialysis. Only small numbers of child...

A PVC membrane electrode based on 1-[({[(butylsulfunyl)carbothioyl]disulfanyl} carbothioyl)sulfanyl]butane as a suitable ion carrier for determination of lanthanum(III) ion was prepared. This electrode revealedsuch a good selectivity toward La3+ ion over a wide variety of other metal ions. Some experimental parametersuch as membrane composition, nature, and amount of plasticizer, the amount of ...

Numerical simulation can provide a valuable tool in evaluating the characteristics of possible sites for new telescopes. This technique can provide accurate information about topographically induced atmospheric disturbances and turbulent boundary layers occurring in the high Reynolds number airflows over such sites. Results are given here for simulations of airflow at the two Gemini 8-m telesco...

This overview addresses potential error control redundancy that may be inherent in running iSCSI over wide area IP networks. In effect the iSCSI standard recommends the use of a 32 bit error control CRC on iSCSI data frames, typically 8KBytes. In a similar manner the TCP transport layer provides a TCP 16 bit checksum on each TCP data packet, typically 1500 bytes, and the Ethernet physical layer...

Radio over fibre (RoF) techniques [1] have been researched from many years and although there are numerous deployments world-wide, the technology is still to have a major impact on mainstream wireless and cellular networks [2]. To date the offerings of the major vendors such as Andrew, ADC and Zinwave, have focused on what are essentially distributed antenna systems. However, as this paper will...

Abstract Potential flow over rotating cylinder is usually solved by the singularity method. However, in this paper a mathematical solution is presented for this problem by direct solution of the Laplace's equation. Flow over the cylinder was considered non-viscous. Neumann and Dirichlet boundary conditions were used on the solid surfaces and in the infinity, respectively. Because of non-viscous...
