Peace journalism–critical discourse case study: media and the plan for Swedish and Norwegian defence cooperation

PURPOSE: To describe the occurrence of atypical, bilateral detachment of the macular neuroepithelium and Klinefelter syndrome in a young patient. METHODS: Case report. RESULTS: A 20-year-old male of Chinese origin with karyotype 47,XXY presented with bilateral central neurosensory retinal detachment. There was spontaneous improvement. CONCLUSIONS: An atypical form of detachment of the macular neuroepithelium was seen in a young patient with Klinefelter syndrome. The pathophysiological mechanism is not clear. The possibility of a hormonal imbalance is discussed. A differential diagnostic consideration is central serous chorioretinopathy and a mild form of Vogt-Koyanagi-Harada syndrome. This case is of interest because of the rarity of association between Klinefelter syndrome and chorioretinal abnormalities

Automated interpretation of benthic stereo imagery

Autonomous benthic imaging, reduces human risk and increases the amount of collected data. However, manually interpreting these high volumes of data is onerous, time consuming and in many cases, infeasible. The objective of this thesis is to improve the scientific utility of the large image datasets. Fine-scale terrain complexity is typically quantified by rugosity and measured by divers using chains and tape measures. This thesis proposes a new technique for measuring terrain complexity from 3D stereo image reconstructions, which is non-contact and can be calculated at multiple scales over large spatial extents. Using robots, terrain complexity can be measured without endangering humans, beyond scuba depths. Results show that this approach is more robust, flexible and easily repeatable than traditional methods. These proposed terrain complexity features are combined with visual colour and texture descriptors and applied to classifying imagery. New multi-dataset feature selection methods are proposed for performing feature selection across multiple datasets, and are shown to improve the overall classification performance. The results show that the most informative predictors of benthic habitat types are the new terrain complexity measurements. This thesis presents a method that aims to reduce human labelling effort, while maximising classification performance by combining pre-clustering with active learning. The results support that utilising the structure of the unlabelled data in conjunction with uncertainty sampling can significantly reduce the number of labels required for a given level of accuracy. Typically 0.00001–0.00007% of image data is annotated and processed for science purposes (20–50 points in 1–2% of the images). This thesis proposes a framework that uses existing human-annotated point labels to train a superpixel-based automated classification system, which can extrapolate the classified results to every pixel across all the images of an entire survey

Bilateral, anterior stromal ring opacity of the cornea

AIMS/BACKGROUND: To describe a bilateral, mid peripheral, ring-shaped corneal opacity, not resembling any known corneal degeneration, dystrophy, or other disorder, and occurring without ocular or systemic disease. METHODS: Ophthalmic examination, haematological screening, and ultrasound biomicroscopy. RESULTS: A 25 year old man showed grey-white, granular opacities in both corneas, with an 8 mm diameter ring configuration, and a V-shaped distribution in the anterior stroma. The surrounding corneal stroma was clear, and the tear film, the epithelium and its basement membrane, Descemet's membrane, and the endothelium were normal. Evidence of systemic disease was not found. Family members did not show corneal abnormalities. CONCLUSION: A bilateral corneal ring opacity may occur in healthy, asymptomatic, young people. These corneal rings may result from depositions of unknown origin, or possibly a rare corneal dystrophy
