To solve the problem of the fuzzy and dynamics of requirement caused by users’ cognitive bias, a dynamic requirement and priority capture method based on user scenarios is proposed, aiming at effectively improving user experience. The method consists of the following steps: Firstly, users with similar characteristics are filtered to form a user cluster, then obtain the user’s product experience in different usage scenarios and acquire preliminary requirements by using service design methods. Secondly, the requirement path model tree will be designed and the requirement path matrix will be constructed through the evaluation of the user cluster. Then the pathfinder algorithm will be used to calculate the required correlation of user clusters and prioritize the requirements. Finally, the direction of the product design will be provided. Taking the design of the intelligent office chair as an example, the effectiveness of the method is verified by evaluating the satisfaction of user experience.

Abstract BACKGROUND Despite its increasing use, circulating tumor cells (CTCs) have not been studied in pediatric brain tumors. METHODS Cell surface vimentin (CSV) is a marker for CTC detection. We developed an automated CSV-based CTC capture method for pediatric brain tumor using the Abnova Cytoquest platform. PBMCs isolated from blood samples from 52 brain tumor patients were processed to isolate CSV+ CTCs. Captured cells were then stained for CSV and CD45 and scanned to determine the number of CTCs. DIPG samples were additionally examined for H3K27M expression on CSV+ cells. Long term cancer survivors were used as a control cohort. RESULTS 86.4% of all the samples exhibited between 1–13 CSV+ CTCs, with a median of 2 CSV+ CTCs per sample. Using a value of ≥ 1 CTC as a positive result, the sensitivity and specificity of this test was 83.05% and 60.0% respectively. 19 DIPG samples were analyzed and 70% (13 samples) were positive for 1–5 CTCs. Five of these 7 positive CSV+ CTCs DIPG samples were also positive for H3K27M mutations by immunohistochemistry (71%). Mean survival in days for the CTC positive and negative DIPG samples were 114 and 211 days, respectively (p= 0.13). CONCLUSION This is the first study of CTCs in pediatric CNS tumors using an automated approach. Patients with brain tumors can exhibit CSV+ CTCs within peripheral blood. The use of specific molecular markers such as H3K27M can improve the diagnostic capability of liquid biopsies and may enable future disease assessment for personalized therapy.

White-clawed crayfishAustropotamobius pallipes(Lereboullet, 1858) are one of five crayfish species indigenous to Europe, and the only crayfish species to occur in Ireland. With no known invasive species posing a risk, the Irish population is of considerable conservation importance, particularly in a European context. While there are a number of capture techniques described for crayfish population studies, many have a number of limitations associated with them. There is a need therefore to evaluate new and emerging techniques, so as to assess their efficacy for monitoringA. pallipespopulations. Artificial refuge traps (ARTs), an alternative passive capture method, were evaluated against three other widely used capture techniques during the summer months of 2015. Results indicate ARTs to be an effective technique for sampling crayfish, and suggest that, in combination with other capture methods, ARTs could depict accurate population structures, and reduce some of the sampling effort and bias associated with crayfish monitoring.

The electron capture method was applied to protoporphyrin IX and meso- porphyrin IX dimethyl esters, metal-free phthalocyanine, chlorophyll, riboflavine, nicotinamide, tetracene, and pentacene. The energy quantities obtained correlated with calculated energies of the lowest empty molecular orbitals of these molecules.
