Geomorphic patterns, internal architecture and reef growth in a macrotidal, high-turbidity setting of coral reefs from the Kimberley bioregion
The coral reefs of the Kimberley bioregion are situated in an area that is considered a significant ‘biodiversity hotspot’ and are poorly known and of recognised international significance. This paper is a review of ongoing research as part of one of the first geoscientific reef studies of the Kimberley Biozone. Remote sensing, sub-bottom profiling and associated sedimentological work have been employed to produce a regional geodatabase of coral reefs and determine the Holocene internal architecture and growth history of the coral reefs. Satellite image analysis has revealed that fringing reefs in the Kimberley bioregion grow very well and differ geomorphologically from planar reefs both inshore and offshore. The acoustic profiles have depicted multiple reef build-ups, demonstrating the reefs’ long-term resilience. This research has provided a better understanding of the Kimberley reefs and demonstrated their capacity to succeed in challenging environments and generate habitats characterised by high complexity and species diversity
Cervical spine radiculopathy epidemiology: systematic review
Background and objective: Cervical spine radiculopathy (CSR) is a disabling condition that has significant negative impacts on a person's mental health, physical functioning and social participation. Research has reported variable CSR incidence and prevalence among different populations. To date, no systematic review has been completed investigating the prevalence or incidence of CSR; therefore, our objective was to determine the incidence and/or prevalence of CSR in adults. Design and method: A systematic review was conducted including searches of PubMed (MEDLINE), EMBASE and CINAHL from inception to February 25, 2020. Studies including data on incidence and/or prevalence of CSR were included. Methodological quality was assessed using a modified Hayden, Cote and Bombardier appraisal checklist. Data were analysed narratively. Results: Nine low- to high-quality studies were included in the final review. Incidence ranged between 0.832 and 1.79 per 1,000 person-years from two high-quality and one low-quality study. Prevalence values ranged from 1.21 to 5.8 per 1,000 from four medium- to high-quality studies. Prevalence values of 1.14% [95% confidence interval (CI): 0.45–1.82] and 1.31% (95% CI: 0.66–1.96) for males and females, respectively, were reported from one medium-quality study. One medium-quality study reported an unadjusted prevalence value of 6.3% for males and females. Conclusions: This is the first systematic review investigating the epidemiology of CSR in an adult population. This review reports a variable incidence rate and prevalence of CSR among specific populations; however, this was based on nine studies. There is a priority to investigate CSR epidemiology across other populations globally and standardising CSR diagnostic criteria

Measurement of the mass difference and relative production rate of the ωb- and Ξb- baryons
The mass difference between the ωb- and Ξb- baryons is measured using proton-proton collision data collected by the LHCb experiment, corresponding to an integrated luminosity of 9 fb-1, and is found to be m(ωb-)-m(Ξb-)=248.54±0.51(stat)±0.38(syst) MeV/c2. The mass of the ωb- baryon is measured to be m(ωb-)=6045.9±0.5(stat)±0.6(syst) MeV/c2. This is the most precise determination of the ωb- mass to date. In addition, the production rate of ωb- baryons relative to that of Ξb- baryons is measured for the first time in pp collisions, using an LHCb dataset collected at a center-of-mass energy of 13 TeV and corresponding to an integrated luminosity of 6 fb-1. Reconstructing beauty baryons in the kinematic region 2<η<6 and pT<20 GeV/c with their decays to a J/ψ meson and a hyperon, the ratio fωb-fΞb-×B(ωb-→J/ψω-)B(Ξb-→J/ψΞ-)=0.120±0.008(stat)±0.008(syst), is obtained, where fωb- and fΞb- are the fragmentation fractions of b quarks into ωb- and Ξb- baryons, respectively, and B represents the branching fractions of their respective decays

Measurement of the Time-Integrated CP Asymmetry in D0 →k-K+ Decays
The time-integrated CP asymmetry in the Cabibbo-suppressed decay D0→K-K+ is measured using proton-proton collision data, corresponding to an integrated luminosity of 5.7 fb-1 collected at a center-of-mass energy of 13 TeV with the LHCb detector. The D0 mesons are required to originate from promptly produced D∗+→D0π+ decays, and the charge of the companion pion is used to determine the flavor of the charm meson at production. The time-integrated CP asymmetry is measured to be ACP(K-K+)=[6.8±5.4±1.6]×10-4 where the first uncertainty is statistical and the second systematic. The direct CP asymmetries in D0→K-K+ and D0→π-π+ decays, aK-K+d and aπ-π+d, are derived by combining ACP(K-K+) with the time-integrated CP asymmetry difference, ΔACP=ACP(K-K+)-ACP(π-π+), and other inputs, giving aK-K+d=(7.7±5.7)×10-4,aπ-π+d=(23.2±6.1)×10-4,with a correlation coefficient corresponding to ρ=0.88. The compatibility of these results with CP symmetry is 1.4 and 3.8 standard deviations for D0→K-K+ and D0→π-π+ decays, respectively. This is the first evidence for direct CP violation in a specific D0 decay. © 2023 CERN. for the LHCb Collaboration.</div
