Dwyer Google Migration

The IT staff at Dwyer Instruments encountered several issues when switching to use Google’s business technology services. These problems included lack of a button to open a new email draft with a PDF already attached, the timestamp function in Google Sheets displaying the current time instead of the time it was entered, duplicate Google Sheets spreadsheets not maintaining protected ranges, lack of a timeline chart in Google Sheets, inability to save Gmail searches, lack of event templates in Google Calendar, and lack of a workflow management tool in Google’s business technology suite. On site personnel were asked to communicate what would help smooth the transition to the G Suite. One challenge encountered was the difficulty in publishing G-Suite add-ons to Google’s online marketplace. Another challenge is presented by the lack of examples of G-Suite add-ons. This makes it tough to create add-ons since there are few resources to go off of. A G-Suite add-on was developed to create an in-page side window in Gmail and Drive to allow attachments from selected conversations or Drive files to be attached and sent with an email. A Google Sheets add-on was also developed in order to insert the current time into a selected cell. While some needs remain outstanding, but the project made significant progress toward solving some of their IT issues

An automated method for comparing motion artifacts in cine four-dimensional computed tomography images.

The aim of this study is to develop an automated method to objectively compare motion artifacts in two four-dimensional computed tomography (4D CT) image sets, and identify the one that would appear to human observers with fewer or smaller artifacts. Our proposed method is based on the difference of the normalized correlation coefficients between edge slices at couch transitions, which we hypothesize may be a suitable metric to identify motion artifacts. We evaluated our method using ten pairs of 4D CT image sets that showed subtle differences in artifacts between images in a pair, which were identifiable by human observers. One set of 4D CT images was sorted using breathing traces in which our clinically implemented 4D CT sorting software miscalculated the respiratory phase, which expectedly led to artifacts in the images. The other set of images consisted of the same images; however, these were sorted using the same breathing traces but with corrected phases. Next we calculated the normalized correlation coefficients between edge slices at all couch transitions for all respiratory phases in both image sets to evaluate for motion artifacts. For nine image set pairs, our method identified the 4D CT sets sorted using the breathing traces with the corrected respiratory phase to result in images with fewer or smaller artifacts, whereas for one image pair, no difference was noted. Two observers independently assessed the accuracy of our method. Both observers identified 9 image sets that were sorted using the breathing traces with corrected respiratory phase as having fewer or smaller artifacts. In summary, using the 4D CT data of ten pairs of 4D CT image sets, we have demonstrated proof of principle that our method is able to replicate the results of two human observers in identifying the image set with fewer or smaller artifacts

Consumer E-Service Evaluation in Hong Kong Online Music Subscription Service Industry

This study investigates into factors affecting the success of E-service using a research model grounded on the Updated DeLone and McLean Information System Success Model (DeLone & McLean, 2003). Fourteen factors originated from four constructs, i.e., system quality, information quality, service quality, and vendor dimensions, are included in our research model. Using the online music subscription industry in Hong Kong as the platform of our investigation, we examine the associations between these four constructs and customer preference in the online music subscription service industry in Hong Kong. We collected data from 135 college students from Hong Kong to test our model using the Analytical Hierarchy Process (AHP). We show that each E-business success construct in our model has different levels of importance in E-service success in the online music subscription service industry. Our findings provide decision makers of E-business firms with useful insights to enhance their E-service quality

Open Science Saves Lives: Lessons from the COVID-19 Pandemic

In the last decade Open Science principles, such as Open Access, study preregistration, use of preprints, making available data and code, and open peer review, have been successfully advocated for and are being slowly adopted in many different research communities. In response to the COVID-19 pandemic many publishers and researchers have sped up their adoption of some of these Open Science practices, sometimes embracing them fully and sometimes partially or in a sub-optimal manner. In this article, we express concerns about the violation of some of the Open Science principles and its potential impact on the quality of research output. We provide evidence of the misuses of these principles at different stages of the scientific process. We call for a wider adoption of Open Science practices in the hope that this work will encourage a broader endorsement of Open Science principles and serve as a reminder that science should always be a rigorous process, reliable and transparent, especially in the context of a pandemic where research findings are being translated into practice even more rapidly

The adherence to guideline-directed therapy post-surgical revascularisation in coronary artery disease and its effect on postoperative outcomes

Background: The American Heart Association (AHA) in 2015 released a scientific statement with regards to secondary prevention after Coronary Artery Bypass Graft surgery (CABG) [1] where advice around antiplatelet, antihypertensives, beta-blockers, and anti-lipids post CABG for secondary prevention is prescribed. This paper reviewed adherence at a single center after discharge with AHA guidelines for secondary prevention after CABG [1] and the effect this had on outcomes. Methods: All CABG patients at Liverpool Hospital, NSW, Australia from 2016-2018 were retrospectively analyzed using the cardiac surgery database. Univariate and multivariate analysis to thirty-day mortality was performed (STATA v16.1). Secondary outcomes of morbidity were reviewed. Results: Adherence to AHA Guidelines in nine hundred and sixteen patients who underwent CABG was analyzed. Antiplatelet therapy (96.9%), beta-blocker (88.3%), anti-lipid (90.1%), antihypertensive (38.4%), and total adherence (33.62%). Adherence influenced outcomes of thirty-day mortality and post-operative Myocardial Infarction (MI) but not in post-operative stroke or revascularization rates. Multivariate analysis found that antiplatelet (OR 0.06, 95% CI 0.02-0.25, p<0.001) and anti-lipid therapy (OR 0.26, 95% CI 0.08-0.89, p=0.032) were protective factors against thirty-day mortality, with Peripheral Vascular Disease (PVD) (OR 7.98, 95% CI 2.00-31.80, p=0.003) predicting mortality in this cohort. Conclusion: Adherence rates to AHA guidelines for secondary prevention post-surgical revascularisation were found to be comparable to that reported in the literature at discharge from the hospital. The independent importance of adherence to antiplatelet therapy and anti-lipid therapy was shown in this cohort in addition to the independent negative effects of PVD on thirty-day mortality. This highlights the importance of adherence to guideline-directed therapies
