Na234SO4 was infused into the rumen of a sheep fed a dried grass diet. 2. The digesta at the pylorus which contained 35S-labelled cyst(e)ine synthesized by the rumen microflora was collected and mixed with chromium EDTA. This material was infused into the duodenum of 35S free sheep. 3. Ileal digesta was subsequently collected and analysed for cyst(e)ine 35S(More)
Random forests are among the most popular classification and regression methods used in industrial applications. To be effective, the parameters of random forests must be carefully tuned. This is usually done by choosing values that minimize the prediction error on a held out dataset. We argue that error reduction is only one of several metrics that must be(More)
A low-cost, low-current consumption 2.42.5GHz MMIC power amplifier operating at 3.3V single supply has been developed for high data rate, wide-range portable WLAN applications. The MMIC utilizes a Fairchild-proprietary InGaP HBT process that enables the design of high power density and extremely linear circuits at frequencies exceeding 6GHz. The MMIC design(More)
Cyst(e)ine synthesized by microorganisms in the caecum of sheep was labelled following the infusion of Na2 35SO4 into the terminal ileum. [35S]Cyst(e)ine activity was detected in the faeces, but not in plasma or wool. Appreciable absorption of 35S, presumably in the form of sulphide, into the circulation occurred, and its presence in saliva was(More)
We compute molecular continuum orbitals in the single center expansion scheme. We then employ these orbitals to obtain molecular Auger rates and single-photon ionization cross sections to study the interaction of N2 with Free-Electron-Laser (FEL) pulses. The nuclei are kept fixed. We formulate rate equations for the energetically allowed molecular and(More)
