A fully consistent and conservative vertically adaptive coordinate system for SLIM 3D v0.4 with an application to the thermocline oscillations of Lake Tanganyika
The discontinuous Galerkin (DG) finite element method is well suited for the
modelling, with a relatively small number of elements, of three-dimensional
flows exhibiting strong velocity or density gradients. Its performance can be
highly enhanced by having recourse to r-adaptivity. Here, a vertical adaptive
mesh method is developed for DG finite elements. This method, originally
designed for finite difference schemes, is based on the vertical diffusion of
the mesh nodes, with the diffusivity controlled by the density jumps at the
mesh element interfaces.
The mesh vertical movement is determined by means of a conservative arbitrary
Lagrangian–Eulerian (ALE) formulation. Though conservativity is naturally
achieved, tracer consistency is obtained by a suitable construction of the
mesh vertical velocity field, which is defined in such a way that it is fully
compatible with the tracer and continuity equations at a discrete level.
The vertically adaptive mesh approach is implemented in the three-dimensional version of the geophysical and
environmental flow Second-generation Louvain-la-Neuve Ice-ocean Model
(SLIM 3D; www.climate.be/slim). Idealised benchmarks, aimed at simulating the
oscillations of a sharp thermocline, are dealt with. Then, the relevance of the vertical adaptivity technique is
assessed by simulating thermocline oscillations of Lake Tanganyika. The
results are compared to measured vertical profiles of temperature, showing
similar stratification and outcropping events

Pediatric Outcome after Maternal Cancer Diagnosed during Pregnancy
BACKGROUND Data on the long-term outcome of children who are exposed to maternal cancer with or without treatment during pregnancy are lacking. METHODS In this multicenter case-control study, we compared children whose mothers received a diagnosis of cancer during the pregnancy with matched children of women without a cancer diagnosis. We used a health questionnaire and medical files to collect data regarding neonatal and general health. All children were prospectively assessed (by means of a neurologic examination and the Bayley Scales of Infant Development) at 18 months, 36 months, or both. A cardiac assessment was performed at 36 months. RESULTS A total of 129 children (median age, 22 months; range, 12 to 42) were included in the group whose mother had cancer (prenatal-exposure group) with a matching number in the control group. During pregnancy, 96 children (74.4%) were exposed to chemotherapy (alone or in combination with other treatments), 11 (8.5%) to radiotherapy (alone or in combination), 13 (10.1%) to surgery alone, 2 (1.6%) to other drug treatments, and 14 (10.9%) to no treatment. Birth weight was below the 10th percentile in 28 of 127 children (22.0%) in the prenatal-exposure group and in 19 of 125 children (15.2%) in the control group (P = 0.16). There was no significant between-group difference in cognitive development on the basis of the Bayley score (P = 0.08) or in subgroup analyses. The gestational age at birth was correlated with the cognitive outcome in the two study groups. Cardiologic evaluation among 47 children at 36 months of age showed normal cardiac findings. CONCLUSIONS Prenatal exposure to maternal cancer with or without treatment did not impair the cognitive, cardiac, or general development of children in early childhood. Prematurity was correlated with a worse cognitive outcome, but this effect was independent of cancer treatment
