More accuracy with less precision

چکیده

Reducing the numerical precision of forecast model Integrated Forecasting System (IFS) European Centre for Medium-Range Weather Forecasts (ECMWF) from double to single results in significant computational savings without negatively affecting accuracy. The allow increase vertical resolution operational ensemble forecasts 91 137 levels earlier than anticipated and before next upgrade ECMWF's high-performance computing facility. This harmonises medium-range deterministic extended-range forecasts. Increasing substantially improves skill all lead times as well mean climate. will run operationally at IFS cycle 47R2 onwards.

More with less Xist.

S ince the birth of Dolly, the first mammal produced from somatic cell nuclear transfer (SCNT), little progress has been made in the efficiency of cloning. Overall, about 0.5–2% of the embryos reconstructed by SCNT develop to term after transfer of reconstructed embryos to recipient females. In PNAS, Matoba et al. (1) report significant improvement in cloning efficiency by manipulation of the l...

Learning More, with Less

P racticing chemists solve problems via “chemical intuition”, a quality that lets them skip intermediate details and get to the essential result, even if the outcome is counterintuitive to the uninitiated. There is no human shortcut to building this intuition; chemists hone their skills through years of experience of learning and memorizing patterns of molecular structure and reactivity. It is ...

Less is more… (more or less…).

In April 1981 Xerox introduced the Star 8010 workstation, the first commercial system with a Graphical User Interface (GUI) and the first to use the “desktop” metaphor to organize a user’s interactions with the computer. Despite the perception of huge progress, from the perspective of design and usage models, there has been precious little progress in the intervening years. In the tradition of ...
