Exciton trapping in a periodically modulated magnetic field

Exciton effective mass enhancement in coupled quantum wells in electric and magnetic fields

“…The application of magnetic fields to the CQW structure provides an extra degree of control. In exciton systems, magnetic fields are used for trapping [36][37][38], control of superfluidity [39,40], tuning of exciton resonances [41] and studying spin-splitting phenomena [42,43]. The focus of this paper is the exciton effective mass enhancement due to a magnetic field [44].…”

Statistical inference through estimation: Recommendations from the International Society of Physiotherapy Journal Editors

“…This may surprise many readers, given how widely such tests are used in published research. 1,2 It is also surprising that the widespread use of null hypothesis statistical tests has persisted for so long, given that the problems in Box 1 have been repeatedly raised in healthcare journals for decades, 8,9 including physiotherapy journals. 10,11 There has been some movement away from null hypothesis statistical tests, but the use of alternative methods of statistical inference has increased slowly over decades, as seen in analyses of healthcare research, including physiotherapy trials.…”

“…10,11 There has been some movement away from null hypothesis statistical tests, but the use of alternative methods of statistical inference has increased slowly over decades, as seen in analyses of healthcare research, including physiotherapy trials. 2,12 This is despite the availability of alternative methods of statistical inference and promotion of those methods in statistical, medical and physiotherapy journals. 10,[13][14][15][16] Estimation as an alternative approach for statistical inference Although there are multiple alternative approaches to statistical inference, 13 the simplest is estimation.…”

“…Null hypothesis statistical tests are often conducted in healthcare research, 1 including in the physiotherapy field. 2 Despite their widespread use, null hypothesis statistical tests have important limitations. This co-published editorial explains statistical inference using null hypothesis statistical tests and the problems inherent to this approach; examines an alternative approach for statistical inference (known as estimation); and encourages readers of physiotherapy research to become familiar with estimation methods and how the results are interpreted.…”
