The manuscript presents so far unpublished high-quality aircraft measurements of CO2, CO and CH4 from three large wildfires and one prescribed fire in mixed conifer forests of the northwestern United States. From these measurements, the author calculates emission factors (EF) for these species and analyses the relationship between observed modified combustion efficiency (MCE) and EFCH4. The aut...
Understanding of species interactions within mesophotic coral ecosystems (MCEs; ~ 30-150 m) lags well behind that for shallow coral reefs. MCEs are often sites of fish spawning aggregations (FSAs) for a variety of species, including many groupers. Such reproductive fish aggregations represent temporal concentrations of potential prey that may be drivers of habitat use by predatory species, incl...
Background—This study investigated whether the extent of perfusion defect determined by intravenous myocardial contrast echocardiography (MCE) in patients with acute myocardial infarction (AMI) treated by primary percutaneous transluminal coronary angioplasty (PTCA) relates to coronary flow reserve (CRF) for assessment of myocardial reperfusion and is predictive for left ventricular recovery. M...
Multi-criteria Evaluation (MCE) is increasingly being used in the assessment of natural resource management options which involve complex ecological, economic and social outcomes and interactions. This paper draws on the results of research experiences and reviews MCE applications to identify methodological issues with conducting MCE and future research possibilities. Some of the key issues tha...
OBJECTIVES The association of peripheral arterial occlusive disease (PAD) association with major coronary events (MCE) has been well documented, nevertheless data are lacking for populations with a low incidence of coronary heart disease (CHD). We aimed to assess the association of PAD with MCE in a Mediterranean population. DESIGN Prospective survey of 699 55-74 year-old men representative o...
BACKGROUND We hypothesized that myocardial contrast echocardiography (MCE) with leukocyte-targeted microbubbles could temporally and spatially characterize the severity of postischemic myocardial inflammation. METHODS AND RESULTS In 9 open-chest dogs, either the left anterior descending or left circumflex coronary artery was occluded for 90 minutes (n=6), while the remaining dogs served as no...
Large rotating magnetocaloric effect (MCE) has been observed in some single crystals due to strong magnetocrystalline anisotropy. By utilizing the rotating MCE, a new type of rotary magnetic refrigerator can be constructed, which could be more simplified and efficient than the conventional one. However, compared with polycrystalline materials, the high cost and complexity of preparation for sin...
BACKGROUND The use of the vasodilating agent adenosine as stressor in conjunction with myocardial contrast echocardiography has not been extensively evaluated in hypertensive patients. Our aim was to evaluate the diagnostic value of adenosine myocardial contrast echocardiography (MCE) in comparison to single-photon emission computed tomography (SPECT), with reference to angiographic findings, i...
Dimensionality reduction is an important problem in pattern recognition. Reducing the dimensionality of feature can improve the effecitveness and efficiency of pattern recognition algorithms. Minimum Classification Error(MCE) training algorithm is a power tool for dimensionality resuction. However, MCE training process is a type of thorough search process for the local minimum, global minimum c...
The magnetocaloric effect MCE was measured to probe the nature of phase coexistence of structurally different ferromagnetic metallic FMM and charge-ordered insulating phases in La5/8−yPryCa3/8MnO3 y =0.275 single crystals. The MCE peaks with both positive and negative values are observed in the vicinity of the multiple-phase transitions in the system. Strain associated with the phase coexistenc...
