Convective structure and its evolution in tropical cyclones as observed by passive microwave sensors in relation to intensity change
… coordinates and evaluated in terms of intensity (wind speed) and intensity change (wind speed change over time). To examine predictive potential of these sensors, the brightness temperature statistics are evaluated in terms of linear correlations between intensity and its change. …

The influence of sound envelope shape on instrumental music educators' preferences for concert band crescendos
… a concert band crescendo with different rates of intensity change. Music educators (N = 62) rated six recordings of a crescendo performed by a digital concert band for similarity to an "ideal concert band crescendo." Each recording was altered to specifically examine a recommended technique for …

Polarization-Maintaining Fiber-Based Optical Coherence Tomography on Functional Imaging in Dense Nerve
… imaging have been performed to capture transient changes during neural activity. The OCT signals including optical path length variation of the nerve with respect to a reference surface (∆P), intensity change (∆I), and normalized intensity change (∆I/I ̂ ) were assessed for potential indications …

Low Energy Electronic Raman Scattering in Cuprate High Temperature Superconductors
… the critical temperature. The measured peak intensity as a function of temperature, however, shows an anomalous behavior. A magnetic field is observed to affect Raman spectra in way similar to the way temperature does. Nevertheless, the peak intensity change as a function of magnetic field is …

Determinants of energy intensity in industrialized countries : a comparison of China and India
… gross domestic product, or GDP), known as energy intensity, is often used to measure the effectiveness of energy use and the consumption patterns of different economies. China and India are both developing countries with large population and rapid economic growth. China has decreased its energy …

Structure and Ozone Decomposition Reactivity of Supported Manganese Oxide Catalysts
… showed a chemical shift to lower energy and an intensity change in the L-edge features which followed the trend Al₂O₃ > ZrO₂ > TiO₂ > SiO₂. The trends provided insights into the positive role of available empty electronic states required in the reduction step of a redox reaction. The catalysts …

Interannual variability of the Atlantic Hadley circulation in boreal summer and its impacts on tropical cyclone activity
… 45% of the variances, is associated with the intensity change of the ITCZ. M1 is significantly correlated to multiple climate factors and has strong impacts on the Atlantic tropical cyclone (TC) activity. In the positive (negative) phase of M1, the ITCZ is stronger (weaker) than normal, and …

Regional Differences in the Spatial Patterns of Precipitation Bands in Hurricanes Through Landfall along the Gulf of Mexico and Atlantic Coasts of the United States
… models due to the rapid nature of TC structure changes that accompany intensity change. To better understand quantitative changes in TC rainband structure around landfall, I quantify the spatial distribution of precipitation in 62 landfalling TCs along the Gulf of Mexico and Atlantic coasts of …

Fast photoemissive probes for shock compression spectroscopy
… which were found to have 3.5× improved emission intensity under steady-state irradiation than the same dye in solution. When the dye-doped microspheres are embedded in polymer and subjected to planar shock compression, the photoemission redshifts and loses intensity. The dye emission redshift …

Functional Magnetic Resonance Imaging of Peripheral Neuropathic Pain in the Spinal Cord and Brainstem
… atlases. We observed consistent signal intensity change in areas implicated in the transmission and modulation of pain in both control and CTS groups. Both groups showed a similar decrease in signal change with increasing pain, as results at pain level 2 are predominantly positive signal …

Three dimensional characterization of failure evolution of tin and silicon in lithium ion battery electrodes
… Relationships between the gray scale intensity change, volumetric expansion, and particle size were established. A correlation between gray scale intensity and volumetric expansion was also recognized allowing the determination of particles as inactive, partially active, or fully …

China energy issues : energy intensity, coal liquefaction, and carbon pricing
… I examine the drivers for provincial energy-intensity trends in China, and finds that technology innovation is the key driver. Then, to understand how technology innovation takes place, I examine coal-to-liquids technology and argue that companies' business diversification strategies are the …

Synoptische, diagnostische und numerische Untersuchungen der Intensitätsänderungen von tropischen Wirbelstürmen und Monsuntiefs
The intensity changes of an Australian monsoon depression and typhoons Flo (1990) and Ed (1990) are investigated using operational analyses, diagnostic studies, and numerical model calculations. The analyses are based on gridded data from the Australian Bureau of Meteorology’s (BMRC’s) Tropical …
