The Noel Kempff Climate Action Project in Bolivia, now in its third year, is breaking ground to establish credible and verifiable methods to quantify greenhouse gas benefits of land-use change and forestry (LUCF) projects. Developed under the Activities Implemented Jointly pilot phase, the project conserves natural forests that would otherwise have been(More)
High-harmonic generation (HHG) traditionally combines ~100 near-infrared laser photons to generate bright, phase-matched, extreme ultraviolet beams when the emission from many atoms adds constructively. Here, we show that by guiding a mid-infrared femtosecond laser in a high-pressure gas, ultrahigh harmonics can be generated, up to orders greater than 5000,(More)
T1 and magnetization transfer at a field strength of 7 Tesla were used to discriminate between water accumulation and protein mobilization in tissue undergoing infarction. Twelve rats subjected to acute stroke via intralumenal suture occlusion of the middle cerebral artery, and 19 controls, were studied. In MRI studies to 6 hr post-ictus, serial data(More)
Water exchange across capillary walls couples intra- and extravascular (IV-EV) protons and their magnetization. A bolus i.v. injection of an extracellular MRI contrast agent (MRCA) causes a large increase in the spin-lattice relaxation rate, R1, of water protons in the plasma and blood cells within the capillaries and changes the effective relaxation rate(More)
On 25 February 1989, at a meeting of the British Society for the History of Mathematics, I heard the late Professor Philip Holgate deliver a lecture 'Independent functions. Probability and analysis in Poland between the Wars', the written version of which appears below. The editor has kindly asked me to write a brief introduction to this work, setting it in(More)
EMU is a wide-field radio continuum survey planned for the new Australian Square Kilometre Array Pathfinder (ASKAP) telescope. The primary goal of EMU is to make a deep (rms ∼ 10 µJy/beam) radio continuum survey of the entire Southern Sky at 1.3 GHz, extending as far North as +30 • declination, with a resolution of 10 arcsec. EMU is expected to detect and(More)
Natural forests store a large quantity of carbon, and there is currently great interest in assessing that quantity accurately, since when forests are cleared the carbon is converted to carbon dioxide in the atmosphere. My purpose here is to describe the best scientific methods available for estimating carbon stocks in forests and in the vegetation left(More)
The selective oxidation energetics of isobutane to methacrolein over phosphomolybdic acid and copper(II) phosphomolybdates have been investigated using low-pressure, pseudo-steady-state and temperature-programming techniques. Time-varying flexible least squares methods were used to determine variations in oxidation activation energies as the temperature(More)
