- Fisheries constitute a major threat to marine mammals globally. To evaluate the impact of small-scale fisheries (SSF) on regional under-studied marine mammal populations, we tested a novel and cost-effective approach at three data-limited locations of the central and eastern Mediterranean Sea. Using off-the-shelf GPS loggers to track SSF activities and systematic surveys to map the distribution of marine mammals, we assessed the probability of co-occurrence between SSF and marine mammals by reporting areas of spatial overlap. Spatial overlap between SSF and the core zones of marine mammal distribution (ranging between 21.85–35.4%) was observed in all three locations, indicating potential interaction hotspots. The probability of co-occurrence in those areas varied from 0.5–2.9% depending on the species. The resulting overlap between fishing activity and marine mammals may pose a threat in both directions: higher risk of species entanglement and economic burden on fishers due to gear damage. Despite the spatial and temporal limitations of this pilot study, the proposed approach can provide baseline information on SSF-marine mammal co-occurrence, particularly in financially limited regions. If applied on a larger scale, our method may be used to inform future conservation actions with the aim to reduce pressure on key populations.

AKT1 and neurocognition in schizophrenia

- Objective: Previous research has shown conflicting results for the significance of five v-akt murine thymoma viral oncogene homolog 1 ( AKT1) single-nucleotide polymorphisms (SNPs) to the aetiology of schizophrenia. Neurocognition is a plausible endophenotype for schizophrenia and it was reasoned that the lack of agreement might be due to variability in neurocognition across studies. Therefore, the association of genetic variation in AKT1 with neurocognition was investigated in patients with schizophrenia. Methods: The same five SNPs used in previous studies of the etiology of schizophrenia (rs2494732, rs2498799, rs3730358, rs1130241, and rs3803300) were genotyped in 641 individuals with schizophrenia who had participated in the Clinical Antipsychotic Trials of Intervention Effectiveness (CATIE) project. The primary dependent variable was a neurocognitive composite score and exploratory analyses investigated five domain scores (processing speed, reasoning, verbal memory, working memory, and vigilance). Results: There were no significant asymptotic or empirical associations between any SNP and the neurocognitive composite score. The authors also investigated the association of five-SNP haplotypes with the neurocognitive composite score. A marginally significant association was observed for the neurocognitive composite score with one of the five-SNP haplotypes (global score statistic 19.51, df = 9, permutation p = 0.02). Exploratory analyses of five domain scores (processing speed, reasoning, verbal memory, working memory, and vigilance) were non-significant for all five SNPs. Conclusion: Results published to date for an association between genetic variation in AKT1 with schizophrenia are inconsistent. The results suggest that the AKT1 markers studied are not associated with neurocognition in schizophrenia, and do not support unassessed variation in neurocognitive scores as a reason for this discrepancy.

Using 87Sr/86Sr LA-MC-ICP-MS Transects within Modern and Ancient Calcite Crystals to Determine Fluid Flow Events in Deep Granite Fractures
- 2020

Journal article (peer-reviewed)abstract
- The strontium isotope signature (87Sr/86Sr) of calcite precipitated in rock fractures and faults is a frequently used tool to trace paleofluid flow. However, bedrock fracture networks, such as in Precambrian cratons, have often undergone multiple fracture reactivations resulting in complex sequences of fracture mineral infillings. This includes numerous discrete calcite crystal overgrowths. Conventional 87Sr/86Sr analysis of dissolved bulk samples of such crystals is not feasible as they will result in mixed signatures of several growth zonations. In addition, the zonations are too fine-grained for sub-sampling using micro-drilling. Here, we apply high spatial resolution 87Sr/86Sr spot analysis(80 um) in transects through zoned calcite crystals in deep Paleoproterozoic granitoid fractures using laser ablation multi-collector inductively coupled plasma mass spectrometry (LA-MC-ICP-MS) to trace discrete signs of paleofluid flow events. We compare the outermost calcite growth zone with 87Sr/86Sr values of the present-day groundwater sampled in the same boreholes to distinguish potential modern precipitates. We then connect our results to previously reported radiometric dating and C and O isotope signatures to understand the temporal history and physicochemical evolution of fluid flow within the fractures. Comparisons of modern calcite precipitated in a borehole over a period of 17 years with modern waters prove the concept of using 87Sr/86Sr as a marker for fluid origin in this environment and for how 87Sr/86Sr changed during marine water infiltration. Intermittent calcite precipitation over very long time spans is indicated in calcite of the currently open fractures, showing an evolution of 87Sr/86Sr from ~0.705–0.707—a population dated to ~1.43 billion years—to crystal overgrowth values at ~0.715–0.717 that overlap with the present-day groundwater values.This shows that high spatial resolution Sr isotope analysis of fine-scaled growth zonation within single calcite crystals is applicable for tracing episodic fluid flow in fracture networks.

An EDSL approach to high performance haskell programming
- 2013

In: SIGPLAN Notices (ACM Special Interest Group on Programming Languages). - New York, NY, USA : ACM. - 0730-8566. ; 48:12, s. 1-11

Journal article (peer-reviewed)abstract
- This paper argues for a new methodology for writing high performance Haskell programs by using Embedded Domain Specific Languages. We exemplify the methodology by describing a complete library, meta-repa, which is a reimplementation of parts of the repa library. The paper describes the implementation of meta-repa and contrasts it with the standard approach to writing high performance libraries. We conclude that even though the embedded language approach has an initial cost of defining the language and some syntactic overhead it gives a more tailored programming model, stronger performance guarantees, better control over optimizations, simpler implementation of fusion and inlining and allows for moving type level programming down to value level programming in some cases. We also provide benchmarks showing that meta-repa is as fast, or faster, than repa. Furthermore, meta-repa also includes push arrays and we demonstrate their usefulness for writing certain high performance kernels such as FFT.
