Fugue is the result of a collaboration between artist, musician and computer scientists. The result is an on-going project which provides a new way of communicating complex scientific ideas to any audience. Immersive virtual reality and sound provide an interactive audiovisual interface to the dynamics of a complex system – for this work, an artificial immune system. Participants are able to se...

Simulation in surgery is becoming an important component of surgical education. Training on bench top models has been demonstrated to improve technical skills. The objective of our project was to create a vascular surgery simulation model. The simulation model consists of a platform, artificial blood reservoir, artificial blood, inflow and outflow limbs, electric motor, battery, pulse generator...

To assess the impact of light scatter, similar to that introduced by cataract on retinal vessel blood oxygen saturation measurements using poly-bead solutions of varying concentrations. Eight healthy, young, non-smoking individuals were enrolled for this study. All subjects underwent digital blood pressure measurements, assessment of non-contact intraocular pressure, pupil dilation and retinal ...

The study of hemodynamics in an animal model simulating coronary stenosis has been limited due to the lack of a safe, accurate and reliable technique for creating an artificial stenosis. Creating artificial stenosis using occluders in an open-chest procedure has often caused myocardial infarction (MI) or severe injury to the vessel resulting in high failure rates. To minimize these issues, clos...

Monte Carlo simulations have been used to analyze oxygenation-related signal changes in pass-band balanced steady state free precession (bSSFP) as well as in gradient echo (GE) and spin echo (SE) sequences. Signal changes were calculated for artificial cylinders and neurovascular networks acquired from the mouse parietal cortex by two-photon laser scanning microscopy at 1 μm isotropic resolutio...

Automatic recognition of an acoustic signature in underwater environments is an important and active field with multiple applications, one of which is vessel recognition. When a vessel moves through the sea, its engine and the cavitation generated by its propellers produce an acoustic wave of unique characteristics that allow for its individual identification. The problem of identification invo...

今回，我々は上腸間膜静脈瘤に対して人工血管置換術を施行したので報告する．症例は80歳の女性で，2019年4月から持続する上腹部不快感を自覚していた．他院の腹部CTで上腸間膜静脈瘤を指摘され当科紹介となった．静脈瘤は上腸間膜静脈と中結腸静脈の合流部に存在し，最大径30 mmであった．手術は，腹部正中切開で施行した．中結腸静脈を結紮し静脈瘤を切除した後に，径10 mmリング付ePTFEで置換した．術後に上腹部不快感は消失した．術後8か月目の造影CTでは人工血管は開存していた．

An investigation is described into the application of artificial intelligence to forecasting in the domain of oceanography. A hybrid approach to forecasting the thermal structure of the water ahead of a moving vessel is presented that combines the ability of a case-based reasoning system for identifying previously encountered similar situations and the generalising ability of an artificial neur...
