We consider the scattering of acoustic perturbations in a presence of a flow. We suppose that the space can be split into a zone where the flow is uniform and a zone where the flow is potential. In the first zone, we apply a Prandtl–Glauert transformation to recover the Helmholtz equation. The well-known setting of boundary element method for the Helmholtz equation is available. In the second z...

This article addresses psychotic patients' fragile boundaries and need for professional help to restore their personal untouchable zone. We examine how nurses move into this inviolable zone and re-establish limits. Empirical data are drawn from an acute psychiatric setting and focus on one patient in different situations and on her relationships with nurses. Data from nurses' discussions and th...

PURPOSE To describe the rationale behind elliptical and other transition designs used with the excimer laser. SETTING Casey Eye Institute, Oregon Health Sciences University, Portland, Oregon, USA. METHODS Ablation zone designs were analyzed for the number of transition points for myopia and hyperopia. The advantages and disadvantages of elliptical transition zones are demonstrated graphical...

In earlier time, we proposed a flat LHM-based hyperthermia scheme for conformal hyperthermia of a large superficial tumor. It is demonstrated that in this scheme by deploying multiple microwave sources in a specific array to shape the heating zone and properly setting the source-to-lens distance or phases of sources to adjust the inclination of heating zone, a heating zone better fit to large s...

Treatment of metastatic castration-resistant prostate cancer is complex and we are facing more questions with major practical impact with the available effective drugs. Treatment optimization requires that all clinical partners work together. Survival is linked to the number of regimen used. The androgen pathway is key, while chemotherapy is the other major tool.

Logic is not just about single-agent notions like reasoning, or zero-agent notions like truth, but also about communication between two or more people. What we tell and ask each other can be just as logical as what we infer in Olympic solitude. We show how communication and other interactive phenomena can be studied systematically by merging epistemic and dynamic logic, leading to new types of ...

Complex social behavior builds on the mutual judgment of individuals as cooperation partners and competitors [1]. Play can be used for assessing the others' dispositions in humans and nonhuman mammals [2], whereas little is known about birds. Recently, food-caching corvids have been found to rival primates in their ability to judge the behaviors and intentions of others in competition for hidde...
