This study explored how to inform the design of information systems for medication therapy management, in the context of the southwestern Ontario health system. The data collection comprised document analysis, interviews, and process mapping, and the analysis of previous interview records. The Functional Resonance Analysis Method (FRAM) was used for data analysis to identify the effects of functional variability in system outcomes, and to propose ways to redesign future systems. The results from the FRAM showed that shortcomings in the information systems require users to adapt in many ways. While these adjustments are essential to delivering care in everyday practice, they may lose their effectiveness in the face of specific situations, creating brittleness and risk of adverse outcomes as users are led to make challenging decisions. © 2019 by Human Factors and Ergonomics Society.

On-road information, including road boundaries, road markings, and road cracks, provides significant guidance or warning to all road users. Recently, the on-road information extraction from LiDAR data have been widely studied. However, for the LiDAR data with lower accuracy and higher noise, some detailed information, such as road boundary, is difficult to be extracted correctly. Furthermore, most of previous studies lack an exploration of efficiently extracting multiple on-road information from a single framework. In this paper, we propose a new framework that can simultaneously extract multiple on-road information from high accuracy LiDAR data and can also more robustly extract detailed road boundaries from low accuracy LiDAR data. First, we propose a Curb-Aware Ground Filter to extract ground points with rich curb structure features. Second, we transform the vertical density, elevation gradient and intensity features of the ground points into multiple feature maps and extract multiple on-road information from the feature maps by employing a semantic segmentation network. Experimental results on three datasets with different data accuracy demonstrate that our method outperforms other recent competitive methods. © 2020 Copernicus GmbH. All rights reserved.

Recent convolutional neural networks (CNNs) in geometric deep-learning for 3D meshes are inadequate in a natural generalisation of CNNs that reduces sample complexity by exploiting symmetries. We propose a novel Group Equivariant Mesh Convolutional Neural Network (GEMnet) using group convolutional layers that exploit a higher degree of weight sharing than the traditional convolution layers, enhancing the expressive ability of the network without fostering additional parameters. Implementing GEMnet layers is easy, with nominal computational overhead for discrete groups produced by translations, rotations, and reflections. Our novel approach operates directly on 3D mesh data for more discriminant feature maps, exhibiting notable improvements across prior stateof-the-art methods. Employing a variety of benchmark datasets, i.e., SHREC with Split 16 & 10 reached 99.83% & 99.33%, Cubes gained 99.17%, and ModelNet40 datasets achieved 95.50% accuracies, respectively, our method surpasses traditional methods for triangular meshes in a classification task. © 2022, The Authors.

Antimony sulfide (Sb2S3) is an appealing one-dimensional light-harvesting material for thin-film solar cells due to the high absorption coefficient, suitable bandgap and abundance of constituent elements. The orientation of the Sb2S3 thin film is considered as one of the most important factors affecting the performance of the device. According to the minimum energy principle, Sb2S3 is prone to grow parallel to the substrate along the [hk0] orientation which is harmful to the device performance. On the other hand, [hk1]-oriented films are much more beneficial but additional processes such as annealing are often required. In this work, stoichiometric Sb2S3 thin films consist of compact, highly [hk1]-oriented grains have been prepared via a self-assembled growth by magnetron sputtering and post-sulfurization. After carefully optimized the preparation process, a champion device (2.89% power conversion efficiency) was obtained with an open-circuit voltage of 696 mV and a short-circuit current density of 12.48 mA/cm2 under AM 1.5G solar radiation. Interestingly, the high open-circuit voltage of our device is already comparable to the state-of-the-art Sb2S3 solar cells. This work demonstrates a great potential of the sputtering and post-sulfurization method in fabrication of high-efficiency substrate Sb2S3 thin-film solar cells. © 2023, The Authors.

Anode materials combining conversion and alloying mechanisms are increasingly valued in advanced rechargeable batteries for their exceptional theoretical capacities and advantageous working voltages. This study showcases BiSCl as a novel conversion/alloying anode material, demonstrating a high specific capacity and enhanced durability through polypyrrole encapsulation. Employing in-situ X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), ex-situ transmission electron microscopy (TEM), and field emission scanning electron microscopy (FESEM), we offer a detailed analysis of the lithiation mechanism in BiSCl. The anode exhibits a low average working potential of approximately 0.6 V, supporting a theoretical specific capacity of 784 mAh g−1 and a volumetric capacity of 4664 mAh cm−3. The innovative BiSCl-PPy core-shell composite effectively addresses the challenges of volumetric expansion and polysulfide dissolution. This composite delivers a remarkable reversible capacity of 753 mAh g–1 at a current rate of 100 mA g−1, maintaining 96% of its specific capacity over 400 cycles, and sustains 419 mAh g–1 at 500 mA g−1 after 800 cycles, demonstrating more superior performance than that of BiSCl. These findings establish BiSCl as a highly promising conversion/alloying anode material for lithium storage, significantly enhanced in durability by the BiSCl-PPy core-shell composite. © 2024, The Authors.

The commercial applications of Li-S batteries are limited by decreased cycling performance caused by the shuttle effect of polysulfides, slower kinetic reaction rates, and lithium anode dendrites. This study demonstrates the important role of diatomite (DT) in regulating cycle performance of modified separator for Li-S batteries. A multifunctional separator (Co/NC/DT) with DT as a carrier assembled high loading Co nanocluster (size 2-4 nm) is prepared. The N-doped carbon is immobilized via Si-N bond between DT and N-doped carbon. The depth profiles of XPS indicates that the ratio of pyrrolic N to pyridinic N of Co/NC/DT reaches 5.31 at the etching of 100 nm vs 0.83 for Co/NC at surface, which suggesting that mainly N species is pyrrolic N after the addition of DT. Theoretical calculations confirm that cobalt nanoclusters grown on pyrrolic N-doped carbon have a lower adsorption energy for a series of polysulfides species compared to that on pyridinic N-doped carbon and can reduce the energy barrier, especially only 0.09 eV for reduction from Li2S6 to Li2S4. In-situ X-ray diffraction analysis confirms Co/NC/DT can effectively promote formation of Li2S. Lithium anode in-situ optical microscopy observation shows the modified separator could reduce lithium dendrites effectively. Li-S battery assembled with the modified separator can reach an initial capacity of 1331.3 mAh g-1 at 0.2 C and cycle 1500 cycles at 1.0 C with a decay of only 0.039% per cycle. Through regulation of DT, Co/NC/DT accelerates the conversion from long-chain sulfur to short-chain sulfur and Li+ transfer rate, resulting in improving cycling performance. © 2024, The Authors.

The second-order magneto-optical effects, represented by Voigt and Schäfer-Hubert effects, are effective methods to detect the spin textures in antiferromagnets, whereas the previous studies are usually limited to collinear antiferromagnets. In noncollinear antiferromagnets, the spin textures characterized by spin chirality have been revealed to play a critical role in many exciting physics. In particular, the first-order topological magneto-optical effects originated from scalar spin chirality have been discovered recently. In this work, using the first-principles calculations and group-theory analysis, we generalize the first-order topological magneto-optical effects to the second-order cases, that is, topological Voigt and Schäfer-Hubert effects, by taking the noncoplanar 3Q spin state of γ−FexMn1−x alloy as an example. The conventional Voigt and Schäfer-Hubert effects are comparatively studied in the collinear 1Q and 2Q spin states of γ−FexMn1−x alloy. In addition, the natural linear birefringence due to crystal anisotropy is discussed in the strained 1Q, 2Q, and 3Q states, and a unique fingerprint for experimentally distinguishing the second-order topological magneto-optical effects and natural linear birefringence is identified. Our work brings a topological insight into the second-order magneto-optical effects in noncoplanar antiferromagnets and also provides γ−FexMn1−x as an attractive material platform for future experimental exploration.

In this work, SiO2 core-shell spheres with a dendritic pore structure were used as chromatographic support and TiO2 was coated into the pores of the SiO2@dSiO2 shell using tetrabutyl orthotitanate (TBOT) as the titanium source. By simply prolonging the reaction time, a TiO2 layer with a uniform and controllable thickness was obtained on the surface of SiO2 core-shell spheres by Ostwald ripening. The thickness of the TiO2 layer can be achieved by either controlling the reaction time or controlling the amount of TBOT. When the concentration of TBOT was 0.06 mol L-1, the thickness of the TiO2 layer can be tuned from 15 to about 44 nm by changing the reaction time. When the concentration of TBOT was 0.08 mol L-1, the thickness of the TiO2 layer can be tuned from 21 to about 71 nm by changing the reaction time. C18-derived core-shell spheres with a TiO2 layer thicknesses of 40 nm (C18-SST-0.5-60) and 70 nm (C18-SST-0.7-30) were used as packings to evaluate the effect of TiO2 layer thickness on the chromatographic separation performance. The separation performance of C18-SST-0.5-60 was better than that of C18-SST-0.7-30. The separation efficiency of C18-SST-0.5-60 and C18-SST-0.7-30 for fluorene was 115112 plates m-1 and 83189 plates m-1, respectively. The columns were also used for the separation of basic, acidic and nucleoside mixtures. Both TiO2-coated core-shell packings showed good peak symmetry for basic samples, with peak asymmetry factors below 1.11. The relative standard deviations of the retention time of polycyclic aromatic hydrocarbons and anilines for intraday, interday and column-to-column variation were all lower than 6%. The results demonstrate that the TiO2 based stationary phase possesses great potential for high performance liquid chromatographic separation. © 2023, The Authors. All rights reserved.
