BACKGROUND Biomedical research increasingly relies on long-term studies involving use and re-use of biological samples and data stored in large repositories or "biobanks" over lengthy periods, often raising questions about whether and when a re-consenting process should be activated. We sought to investigate the views on re-consent of participants in a longitudinal biobank. METHODS We conduct...

Heterogamous marriages, in which partners have dissimilar attributes (e.g. by socio-economic status or ethnicity), are often at elevated risk of dissolution. We investigated the influences of heterogamy by religion and area of residence on risk of marital dissolution in Northern Ireland, a country with a history of conflict and residential segregation along Catholic-Protestant lines. We expecte...

BACKGROUND There are many benefits to open datasets. However, privacy concerns have hampered the widespread creation of open health data. There is a dearth of documented methods and case studies for the creation of public-use health data. We describe a new methodology for creating a longitudinal public health dataset in the context of the Heritage Health Prize (HHP). The HHP is a global data mi...

This study investigates drag reduction capability of naturally occurring-oscillating axial secondary flow (ASF) induced by helical-corrugated surface in Taylor–Couette (TCFHelical) for three values pitch to wavelength ratios (P* = 1, 2, and 3) amplitude ratio(A*) 0.25. As reported Razzak et al. [“Numerical Taylor Couette with longitudinal corrugated surface,” Phys. Fluids 32(5), 053606 (2020)],...

This  case  study  analyzes  how  a  Taiwanese  EFL  teacher  participating  in  a  U.S.  based MATESOL program made sense of systemic functional linguistics (SFL) and genre based pedagogy  in  designing  and  reflecting  on  literacy  instruction  for  EFL  learners  in  Taiwan. Using  longitudinal  ethnographic  methods,  the  findings  indicate  that  this  teacher’s conceptualization  of  g...

background: the celebrated generalized estimating equations (gee) approach is often used in longitudinal data analysis. while this method behaves robustly against misspecification of the working correlation structure, it has some limitations on efficacy of estimators, goodness-of-fit tests and model selection criteria. the quadratic inference functions (qif) is a new statistical methodology tha...

Abstract Experimental measurements and numerical predictions of the longitudinal component air velocity in a narrow channel with two rows 26 densely packed oval trenches at angles ±45° ±135° laminar (Re=10 3 ) turbulent (Re=4×10 regimes have been compared. The acceptability RANS approach using modified SST turbulence model within Rodi–Leschziner–Isaev has substantiated. flow acceleration dimple...
