Microfluidic multipoles: theory and applications

Microfluidic multipoles (MFMs) have been realized experimentally and hold promise for "open-space" biological and chemical surface processing. Whereas convective flow can readily be predicted using hydraulic-electrical analogies, the design of advanced MFMs is constrained by the lack of simple, accurate models to predict mass transport within them. In this work, we introduce the first exact solutions to mass transport in multipolar microfluidics based on the iterative conformal mapping of 2D advection-diffusion around a simple edge into dipoles and multipolar geometries, revealing a rich landscape of transport modes. The models were validated experimentally with a library of 3D printed MFM devices and found in excellent agreement. Following a theory-guided design approach, we further ideated and fabricated two new classes of spatiotemporally reconfigurable MFM devices that are used for processing surfaces with time-varying reagent streams, and to realize a multistep automated immunoassay. Overall, the results set the foundations for exploring, developing, and applying open-space MFMs.Comment: 16 pages, 5 figure

A physician-physiotherapist collaborative model in a family medicine teaching clinic

Persons with musculoskeletal disorders frequently seek care in family medicine clinics. However, musculoskeletal education provided in medical schools is often considered insufficient. The implementation of a collaborative model that integrates physiotherapists into teaching clinics may benefit the musculoskeletal training of medical residents. This paper describes a model developed in a family medicine teaching clinic by examining the interprofessional educational and collaborative activities implemented in this model. The model allowed to provide physiotherapy services, involve the physiotherapist in the training of family medicine residents and enhance interprofessional collaboration, particularly for the management of persons with musculoskeletal disorders._____Les personnes ayant des troubles musculosquelettiques consultent fréquemment en cliniques de médecine de famille. Cependant, l’enseignement musculosquelettique dispensé dans les programmes de médecine est souvent considéré comme insuffisant. L’implantation d’un modèle de collaboration qui intègre les physiothérapeutes aux cliniques d’enseignement pourrait améliorer la formation des médecins résidents. Cet article décrit un modèle développé dans une clinique d’enseignement en médecine familiale en examinant les activités interprofessionnelles d’éducation et de collaboration implantées dans ce modèle. Le modèle a permis d’offrir des services de physiothérapie, d’impliquer le physiothérapeute dans la formation des médecins résidents et d’améliorer la collaboration interprofessionnelle, particulièrement pour la prise en charge des personnes ayant des troubles musculosquelettiques

Integrable Supersymmetry Breaking Perturbations of N=1,2 Superconformal Minimal Models

We display a new integrable perturbation for both N=1 and N=2 superconformal minimal models. These perturbations break supersymmetry explicitly. Their existence was expected on the basis of the classification of integrable perturbations of conformal field theories in terms of distinct classical KdV type hierarchies sharing a common second Hamiltonian structure.Comment: 10 pages (harvmac), LAVAL PHY-20-9
