ASP, The Art and Science of Practice: Academia-Industry Interfacing in Operations Research in Montreal
This paper reports on the 40-year experience of academia-industry interfacing in the operations research (OR) field in Montréal. We focus on five spin off companies that academic entrepreneurs from the CIRRELT and the GERAD created between 1976 and 2003: INRO Consultants, GIRO, AD OPT, Omega Optimisation/Planora, and ExPretio. The importance of university spin offs for knowledge transfer is well documented in fields such as biology and nanotechnology; however, few papers have studied university spin offs in OR. Yet, OR has an enormous impact on society, and university spin off firms play a key role in the diffusion of research to the world of practitioners. In this paper, we tell the story of five companies created by academics from two world-renowned OR research centers based in Montréal, and we derive lessons about academia-industry interfacing in the OR field. By so doing, we hope to improve our understanding of the creation of fruitful relationships between academics and OR practitioners
A Collaborative Effort to Establish a Convalescent Plasma Program in South Florida
On March 11, 2020, Miami-Dade County had its first diagnosed case of COVID-19 and quickly became the top hotspot of COVID-19 cases in Florida. Hospitals were challenged to find effective treatments to combat the virus. A collaborative effort between Doctors Hospital and Boca Raton Regional Hospital established a robust convalescent plasma program for critically ill patients diagnosed with COVID-19 within Baptist Health South Florida
A Collaborative Approach to Reduce the Spread of COVID-19 in a Large Urban Hospital in South Florida
The novel Coronavirus has proven challenging for many healthcare organizations. Hospitals are pressed to secure sufficient personal protective equipment to ensure the safety of their healthcare personnel and various strategies have been implemented to stop the spread of the virus. There are still many unknowns about COVID-19 and hospitals are rapidly adapting to new information while trying to maintain the safety and wellbeing of healthcare personnel. Baptist Hospital of Miami developed a collaborative data driven plan to monitor, disseminate vital information, and implement various strategies to protect employees and patients during the pandemic
A real delivery problem dealt with Monte Carlo techniques
[EN] In this paper we use Monte Carlo Techniques to deal with a real world delivery problem of a food company in Valencia (Spain). The problem is modeled as a set of 11 instances of the well known Vehicle Routing Problem, VRP, with additional time constraints. Given that VRP is a NP-hard problem, a heuristic algorithm, based on Monte Carlo techniques, is implemented. The solution proposed by this heuristic algorithm reaches distance and money savings of about 20% and 5% respectively.This research was partially supported by MICINN, Project MTM2013-43540-P and by UPV, Project Programa de Apoyo a la Investigación y Desarrollo de la UPV PAID-06-12.S577181Fernández de Córdoba, P., L.M.

Impacts of misalignment effects on the Muon Spectrometer Performance
The ATLAS detector, currently being installed at CERN, is designed to exploit the full potential of the LHC, identifying and providing highly accurate energy and momentum measurements of particles emerging from the LHC protonproton collisions with a centre-of-mass energy at 14 TeV, starting in 2007. High-momentum final-state muons are among the most promising signatures at the LHC, thanks to a high-resolution Muon Spectrometer with standalone triggering and momentum measurement. As well known, muons interact primarily trough their electromagnetic charge, but since they are 200 times more massive than the electrons they are less affected by the electric fields of the nuclei they encounter. Muons with an energy of more than a few GeV penetrate the calorimeter and can reach the Muon Spectrometer, which consists out of more than 1.200 single drift-tubes chambers. The correct alignment of the ATLAS Muon Spectrometer is crucial to ensure its design performance. This note documents the first attempt at using various misaligned Muonspectrometer layouts to study their impacts Muon Spectrometer performance
Implementing a Virtual Mobility Education Program to Impact Nursing Knowledge, Attitudes, and Behaviors toward Patient Mobility
Introduction: Older adults aged 65 and over are vulnerable to functional decline during hospitalization and negative outcomes associated with immobility such as pressure injuries and falls. Studies reveal that nurses overlook patient mobilization due to competing priorities and a lack of comfort with patient mobilization. Hospital-associated functional decline can be mitigated through mobilization protocols. A 36-bed medical surgical unit in a South Florida hospital did not have a protocol for patient mobility.
Methods: Nurses’ knowledge, attitudes, and behaviors regarding patient mobility were assessed using a pre-implementation survey. A virtual education program about the mobility protocol was provided via an online platform. Three weeks later, a post-implementation survey was administered to those who attended the education.
Results: Fourteen nurses completed both the pre- and post-test surveys. The nurse-led mobility protocol educational intervention was associated with (a) an increase in average scores from the pre-test nursing mobility attitudes (M = 3.50) and behavior subscales (M = 3.40) to the post-test scores (M = 3.56 and M =3.75, respectively) and (b) a significant increase in the average knowledge scores from the pre-test survey (M = 4.31) to the post test survey (M = 4.62), t(13) = -2.74, p \u3c 0.05.
Discussion: The results suggest that the mobility education was successful in increasing nurse mobilization knowledge. Methods to improve nurses’ attitudes and behaviors toward patient mobility should be further explored
Diversity-oriented synthesis of a library of substituted tetrahydropyrones using oxidative carbon-hydrogen bond activation and click chemistry
Eighteen (2RS,6RS)-2-(4-methoxyphenyl)-6-(substituted ethyl)dihydro- 2Hpyran-4(3H)ones were synthesized via a DDQ-mediated oxidative carbon-hydrogen bond activation reaction. Fourteen of these tetrahydropyrans were substituted with triazoles readily assembled via azide-alkyne click-chemistry reactions. Examples of a linked benzotriazole and pyrazole motif were also prepared. To complement the structural diversity, the alcohol substrates were obtained from stereoselective reductions of the tetrahydropyrone. This library provides rapid access to structurally diverse non-natural compounds to be screened against a variety of biological targets. © 2011 by the authors
