The impact of the mixing properties within the Antarctic stratospheric vortex on ozone loss in spring [PDF]

, 2001
Calculations of equivalent length from an artificial advected tracer provide new insight into the isentropic transport processes occurring within the Antarctic stratospheric vortex. These calculations show two distinct regions of approximately equal area:

Temperature dependence of core loss in cobalt substituted Ni-Zn-Cu ferrites

, 2010
The temperature dependence of core loss in cobalt substituted Ni-Zn-Cu ferrites was investigated. Co2+ ions are known to lead to a compensation of the magneto-crystalline anisotropy in Ni-Zn ferrites, at a temperature depending on the cobalt content and ...

Stability of solitons in PT-symmetric couplers [PDF]

, 2011
Families of analytical solutions are found for symmetric and antisymmetric solitons in the dual-core system with the Kerr nonlinearity and PT-balanced gain and loss. The crucial issue is stability of the solitons.

The Cepheid mass discrepancy and pulsation-driven mass loss [PDF]

, 2011
Context. A longstanding challenge for understanding classical Cepheids is the Cepheid mass discrepancy, where theoretical mass estimates using stellar evolution and stellar pulsation calculations have been found to differ by approximately 10 - 20%. Aims.

Nonlinearity Estimation and Compensation for Accurate PMSM Modeling and Voltage Prediction

CES Transactions on Electrical Machines and Systems
For permanent magnet synchronous machine (PMSM), the machine model is critical to predict the operating states for motor control, which, however, can be greatly affected by system nonlinearities.

Low-Cost High-Sensitivity Strain and Temperature Sensing Using Graded-Index Multimode Fibers [PDF]

, 2007
We report a low-loss, low-cost high-sensitivity all-fiber strain and temperature sensor based on mode interference in graded-index multimode fibers. Blueshifts with strain and temperature sensitivities of 18.6 pm/microstrain and 58.5 pm/°C have been ...

Core-loss EELS

Current Opinion in Solid State and Materials Science, 1998
Abstract It is now possible to create an atom sized electron beam that can probe the electronic structure of materials on the scale. Electrons passed through an electron spectrometer from such a probe give energy loss spectra that can provide insight on the local chemistry, bonding and electronic structure.

Carcinomas and Carcinoid Tumors of the Lungs and Bronchi in Children and Adolescents: The EXPeRT Recommendations

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Primary lung carcinomas and bronchial carcinoid tumors (BC) are very rare malignancies in childhood. While typical BC and mucoepidermoid carcinomas are mostly low‐grade, localized tumors with a more favorable prognosis than in adults, necessitating avoidance of overtreatment, adenocarcinomas of the lung are often diagnosed at advanced disease ...
