Few-shot adaptation for morphology-independent cell instance segmentation

Microscopy data collections are becoming larger and more frequent. Accurate and precise quantitative analysis tools like cell instance segmentation are necessary to benefit from them. This is challenging due to the variability in the data, which requires retraining the segmentation model to maintain high accuracy on new collections. This is needed especially for segmenting cells with elongated and non-convex morphology like bacteria. We propose to reduce the amount of annotation and computing power needed for retraining the model by introducing a few-shot domain adaptation approach that requires annotating only one to five cells of the new data to process and that quickly adapts the model to maintain high accuracy. Our results show a significant boost in accuracy after adaptation to very challenging bacteria datasets.Comment: ISBI 202

The industrial consequences of deficiencies of colour vision

A number of industries involved with coloured products were surveyed to assess the role of visual colour judgement in the processes and determine the industrial handicap of defective colour vision. The colour vision testing policies of the individual companies were investigated and an attempt was made to discover the industrial mistakes which could be attributed to defective colour vision. Visits were made to selected Industries to supplement information obtained from a postal survey. Discussions with Employment Medical Advisers and Industrial Medical Officers proved to be valuable. A field trial to determine the performance of paper colour matchers at standard colour vision tests was undertaken. A number of industrial jobs involving colour judgement were simulated in the laboratory. One hundred colour defective observers and a group of colour normals took part in the tasks, and an analysis of their performance is presented. In particular, comparisons are drawn between performance at these tasks and scores on standard colour vision tests. An enquiry into the colour vision tests used in school medical examinations was made and the career guidance given to colour defective children throughout England and Wales was studied. A list of occupations, jobs and careers which are likely to cause difficulty to the colour defective are presented. Finally recommendations concerning colour vision testing in industry are given

Pregnancy and antibody to factor VIII.

A patient who had developed a factor VIII antibody three weeks after the birth of her first baby became pregnant for the second time 10 weeks later. The pregnancy was normal apart from extensive spontaneous bruising during the first two months. This bleeding tendency disappeared in the third month of gestation and the antibody became undetectable during the eighth month. It has not reappeared seven months later. An unexplained long bleeding time and low platelet count were noted during the last trimester. The literature on postpartum coagulation inhibitors is reviewed
