Research on the depositional record of submarine fans and related turbidite systems has highlighted the importance of channel, lobe and levée–overbank architectural elements as fundamental building blocks. However, many of the characteristics and processes of deposits left by flows traversing those fans remain elusive, because flows seem to be able to go unconfined for long distances. Offshore southern California (USA), the La Jolla Canyon decreases in relief to become an approximately U‐shaped channel across the basin floor of the San Diego Trough. The La Jolla Channel gradually loses confinement and transitions to a network of scours, some of which align to form incipient channels, and fields of bedforms. High‐resolution seafloor topography, CHIRP seismic‐reflection data, sediment cores and hydrodynamic flow analysis are used to explore these features. The focus is on two regions of bedforms: (i) a field of net‐depositional, concentric bedforms across the eastern levée–overbank upstream from the terminus of the La Jolla Channel; and (ii) a linear train of more erosional bedforms approximating an incipient channel adjacent to the present mouth of the La Jolla Channel. These bedforms are interpreted to be among a class of upper‐flow‐regime bedforms called cyclic steps, which were formed by densimetric Froude supercritical turbidity currents that spilled out of the present La Jolla Channel. The high‐resolution data for the La Jolla Fan provide valuable insights into the characteristics of supercritical bedforms likely common to distal submarine fans, as well as on sedimentary processes likely important for submarine fan growth into sedimentary basins. In particular, the pattern of evolution of the La Jolla Fan suggests that cyclic steps with wavelengths on the order of tens of metres to a few hundreds of metres could be fundamentally important for the evolution of the distal submarine fans with relatively low‐relief main channels.

Background: The aim of this study was to assess the impact of the depression on sexual dysfunction and the health-related quality of life (HRQoL) in coronary artery disease (CAD) patients admitted for cardiovascular rehabilitation within 3 months after an acute myocardial infarction (AMI). Methods. In all, 745 consecutive CAD patients (502 men and 243 women, aged 60.9 ± 9.3 years) admitted for cardiovascular rehabilitation within 3 months after an AMI, were enrolled in the study and divided into 4 groups according to Beck depression inventory (BDI) score range. HRQoL was estimated using the SF-36 questionnaire for total QoL and dimensions for physical and mental health [physical and mental component summary scores (PCS, MCS)]. Sexual dysfunction was assessed using the ASEX scale. Results: The HRQoL decreased following the range of depression, as demonstrated for significantly higher PCS in minimal compared to mild, moderate and severe depression groups (P<0.001). The MCS was significantly higher in minimal compared to mild, moderate and severe depression groups (P<0.001). The ASEX score was significantly higher in minimal, compared to mild, moderate and severe depression groups, as well as in mild and moderate compared to severe depression group. A significant association was found between depression score range and age, self-reported regular exercise, type 2 diabetes mellitus, and cigarette smoking. Conclusions: Depression significantly affected HRQoL and sexual dysfunction in CAD patients, as demonstrated by the significant decrease of PCS, MCS, and significant increase of ASEX score following the range of the depression according to BDI.
