Continuous tunability of refractive index contrast in LiNbO3 optical waveguides fabricated by high-vacuum vapor-phase proton exchange by Mihnea Raoul Sandu, Alicia Petronela Rambu, Laura Hrostea, Sorin Tascu

“…Abstract The actual techniques allowing the fabrication of waveguides in lithium niobate are not able to satisfy one of the demands of modern integrated photonics namely the well-controlled tunability of index contrast over a large range of values (from high-index contrast to low index contrast). This paper presents a simple and reliable method allowing well-controlled index contrast tunability between high-index contrast (Δn e  = 0.1) and low-index contrast (Δn e  = 0.035) while benefiting from the optical nonlinearity of LiNbO3 waveguides fabricated using HiVac-VPE technique. …”

Estimating the Potential Modal Split of Any Future Mode Using Revealed Preference Data by Gijsbert Koen de Clercq, Arjan van Binsbergen, Bart van Arem, Maaike Snelder

“…For new modes, the mode-specific parameters and the constant in the utility function of discrete choice models are not known and are difficult to estimate on the basis of stated preferences data/choice experiments and cannot be estimated on the basis of revealed preference data. This paper demonstrates how revealed preference data can be used to estimate a discrete mode choice model without using mode-specific constants and mode-specific parameters. …”

Enhancing professionalism in post-graduate medical education: the initial implementation and evaluation of a longitudinal curriculum for geriatrics residents in Toronto, Canada by Kristina M Kokorelias, Muhammad Harris Sheikh, Maryam Naimi, Bernice Ho, Edwin W Wong, Stephanie G Brooks, Dov Gandell, Arielle S Berger

“…Thematic analysis demonstrated that the curriculum impacted residents in three key thematic areas: (1) it led participants to understand their role as physicians in a more comprehensive way, while staying consistent with their personal values and strengths. (2) Communication skills training in particular equipped learners with important skills needed to enact their professional standards. (3) Through developing a supportive community and practicing mindful self-reflection, participants reported improvements in their well-being. Conclusions: This paper demonstrates that professionalism can and should be integrated into the formal curriculum of post-graduate medical education. …”

Simulation Effect Evaluation of CMIP6 Models on Climatic Elements in Huai River Basin by WU Chen, WANG Jingcai, SHAO Junbo, LI Xiangyu, WANG Wenyue

“…The general climate model (CMIP6) is the main means of large-scale simulation and prediction of future climate changes,but the simulation quality of its model data and applicability in different research regions need to be evaluated.Based on the measured data of 19 meteorological stations in the upper and middle reaches of the Huai River Basin from 1960 to 2014,this paper systematically evaluates the simulated climate data of 19 CMIP6 models using five precision indicators.The indicators include equidistant cumulative distribution function method,mean,dispersion coefficient (C_v),Pearson correlation coefficient (PCC),standard deviation (STD),and root-mean-square deviation (RMSE).Finally,the following conclusions are drawn:① Based on the simulation data of 19 CMIP6 models corrected for bias,the top two climate models for precipitation data simulation are preliminarily selected,including ACCESS-ESM1-5 and CMCC-ESM2.The top five climate models for simulating temperature data contain ACCESS-ESM1-5 and CMCC-ESM2;② The historical period data and measured historical climate data of the selected CMIP6 models are evaluated from two aspects of annual change trend and spatial distribution.Then,the CMIP6 model suitable for the upper and middle reaches of the Huai River Basin is verified and selected;③ Based on analyzing the influence of atmospheric circulation factors on climate,AO has a good correlation with the climate data of the upper and middle reaches of the studied basin,and the correlation between the model and atmospheric circulation data is close to the actual situation.The comprehensive evaluation shows that the most suitable models for simulating the upper and middle reaches of the Huai River Basin are ACCESS-ESM1-5 and CMCC-ESM2.The systematic evaluation of CMIP6 model data simulating the upper and middle reaches of the Huai River Basin provides theoretical and technical references for the rational selection and utilization of CMIP6 datasets for the research on climate change factors in future scenarios of the basin.…”
