We present high-field magnetotransport data from a range of 30-nm-wide InSb/InAlSb quantum wells with room-temperature mobilities in excess of 6 m 2 V −1 s −1. Samples with the narrowest Landau level broadening exhibit beating patterns in the magnetoresistance attributed to zero-field spin splitting. Rashba parameters are extracted from a range of samples(More)
The spin-orbit ͑SO͒ coupling parameters for the lowest conduction subband due to structural inversion asymmetry ͑SIA͒ and bulk inversion asymmetry ͑BIA͒ are calculated for a range of carrier densities in ͓001͔-grown ␦-doped n-type InSb/ In 1−x Al x Sb quantum wells using the established eight-band k · p formalism ͓J.

BACKGROUND Health services are encouraged to adopt a strong person-centered approach to the provision of care and services for older people. The aim of this project was to establish a user-friendly, psychometrically valid, and reliable measure of healthcare staff's practice, attitudes, and beliefs regarding person-centered healthcare.

We would like to draw the reader's attention to two errors which appeared in the text of this paper when referring to references Pfeffer and Zawadzki, 1 and Engels et al. 2 These errors are as follows: In the 4th line of the abstract, 2nd line of Sec. II ͑p. 3͒, and 32nd line of p. 8, references to " Deng et al. " should read " Pfeffer and Zawadzki. " In(More)
BACKGROUND COPD is an umbrella term to describe chronic lung diseases that cause limitations in lung airflow, including emphysema and chronic bronchitis. The prevalence of depression and anxiety in people with COPD is high, although these comorbidities are often undiagnosed, untreated, or undertreated. There is a need to identify efficacious treatments for(More)
A strand of Leslie J Francis' research has maintained an interest in the area of attitudes toward alcohol and substances, and the role of religion in shaping attitude in these areas. The Francis Scale of Attitude toward Alcohol has become a recognised instrument in this field. The relationship between Eysenck's personality factors and attitude towards(More)
We report the optical measurement of the spin dynamics at elevated temperatures and in zero magnetic field for two types of degenerately doped n-InSb quantum wells (QWs), one asymmetric (sample A) and one symmetric (sample B) with regards to the electrostatic potential across the QW. Making use of three directly determined experimental parameters: the spin(More)
