Health Care Students’ Perspectives on Artificial Intelligence: Countrywide Survey in Canada

Background Artificial intelligence (AI) is no longer a futuristic concept; it is increasingly being integrated into health care. As studies on attitudes toward AI have primarily focused on physicians, there is a need to assess the perspectives of students across health care disciplines to inform future curriculum development. Objective This study aims to explore and identify gaps in the knowledge that Canadian health care students have regarding AI, capture how health care students in different fields differ in their knowledge and perspectives on AI, and present student-identified ways that AI literacy may be incorporated into the health care curriculum. Methods The survey was developed from a narrative literature review of topics in attitudinal surveys on AI. The final survey comprised 15 items, including multiple-choice questions, pick-group-rank questions, 11-point Likert scale items, slider scale questions, and narrative questions. We used snowball and convenience sampling methods by distributing an email with a description and a link to the web-based survey to representatives from 18 Canadian schools. Results A total of 2167 students across 10 different health professions from 18 universities across Canada responded to the survey. Overall, 78.77% (1707/2167) predicted that AI technology would affect their careers within the coming decade and 74.5% (1595/2167) reported a positive outlook toward the emerging role of AI in their respective fields. Attitudes toward AI varied by discipline. Students, even those opposed to AI, identified the need to incorporate a basic understanding of AI into their curricula. Conclusions We performed a nationwide survey of health care students across 10 different health professions in Canada. The findings would inform student-identified topics within AI and their preferred delivery formats, which would advance education across different health care professions.

Assessment of proposed business plans of on-trip and pre-trip information in the LRT system (public urban transit)of the city of Zagreb

The quality of public urban transit organization depends to a great extent also on the organization and the quality of on-trip and pre-trip information services. The aim of this service is to provide relevant, accurate and usable traffic and transport information to current users of the public urban transit, as well as to attract new users, alleviating the burden on the roads and insuring high-quality transport service to motorists who at least on one section of their trip use public transport means. Apart from classical information forms this system greatly relies also on new telecommunication technologies including the third generation of mobile networks and mobile Internet. Apart from the wide range of methods of collecting information, their processing and dissemination, the entire problems of introducing the mentioned services into the newly organized system such as LRT needs to be systemically analyzed. It is especially important to analyze in advance and to define the relations between the private and public sector in the described process. The corporate plans of organizing the system of on-trip and pre-trip information in the LRT system applicable in the City of Zagrebare considered. Their implementability has been evaluated by a professional team defining the relevant factors in the selection of the corporate plan.

Energy Wave Transmission and Control Analysis in Force Reflection Teleoperation Based on Interconnected Power Line

Force-Reflected Telepresence Teleoperation system has been widely used. Generally, force and torque sensors are installed on the robot to realize haptic perception. Control commands and force-reflected information from the robot are transmitted by communication link, such as internet. However, this structure not only brings difficulties of installation and commissioning, but also reduces the system flexibility and makes control more difficult. And it is prone to interfered in microenvironment. This paper presents a new type of energy transfer method to achieve it by power line instead of internet between the Master-slave Manipulators. This method achieves the consistency of force-reflected without using sensors to measure the conditions. In practical application, it requires to design an energy managed controller to insure the stability and obtain precision in synchronization between the master part and slave part. This paper gives the theory, the system structure and control method of force telepresence teleoperation based on power line.
A Practical Post-Processing Method to Obtain Wave Parameters from Phase-Resolving Wave Model Results

This paper describes a new method to obtain directional and amplitude information from the results of phase-resolving computational wave models. The output of this type of models is the wave field resulting from incoming and reflected wave components combined, whereas specific information on separate wave components (directions, heights, periods) is generally required for design purposes. The new post-processing method that we present to obtain this information has been validated using analytically prescribed wave signals as well as results from a mild-slope model, which is the phase-resolving wave model that has been considered so far. The versatility and usefulness of the method is illustrated in a number of application examples for ports. The results show that the new method is practical and produces reliable results.

Does psychological work environment matter? Relationship between psychological climate reflecting individual perception of work environment and stress among public servants

Abstract This study examines how individual perceptions of the work environment reflecting the psychological climate could influence the stress felt by public servants. This study adopts a transactional perspective to argue that valuation of the work environment and the job itself influences the perception of potential stressors and hypothesizes the relationship between the self-engagement psychological climate, stress, and intention to stay in public service. The proposed hypotheses are validated through a cross-sectional survey of 332 public servants in Switzerland. First, the study finds that role clarity, contribution, and supportive management characterize the psychological climate of public servants. Second, the results of the multiple regression analysis indicate that the psychological climate reduces the felt stress with the highest impact of the role clarity. Third, mediation analysis indicates that the psychological climate mediates the relationship between intention to stay and stress. These findings suggest an important theoretical role for the work environment perception in alleviating stress. In practice, findings imply that public managers can foster a higher psychological climate by setting clear organizational roles and predictable task norms, as well as by providing opportunities for career development.
Effect of alloying on the structure and electric properties of ZnFe2O4/ZnMn2O4 heterostructure nanocomposites

The heterostructure nanocomposite (1-x)ZnFe2O4/xZnMn2O4 (x = 0, 0.5, 0.8, 1) samples were prepared using the sol–gel method. The structural parameters and the percentages of the phases formed were determined utilizing the Rietveld method. Beside the two phases formed ZnFe2O4 (ZFO) and ZnMn2O4 (ZMO), a minor phase ZnO (3%) was observed in the sample x = 0.5. Analysis revealed phase percentages for composite samples different from intended (x) values due to the exchange of cations between the phases formed. The effect of composition ratio (x), as well as the frequency and temperature on the dielectric constant, dielectric loss, impedance spectroscopy and complex electric modulus and ac conductivity, was examined. The degree of correlation in each sample was also determined. Different conductivity mechanisms are found for different samples and frequency ranges. The 0.2ZFO-0.8ZMO sample disclosed higher conductivity and higher dispersion relative to other samples. The effect of temperature on the Cole–Cole plots was also studied. GRAPHICAL ABSTRACT
5.3.2 Design of the Reconnaissance, Surveillance and Target Acquisition Squadron for the U.S. Army's Interim Brigade Combat Team

The primary source of battlespace intelligence for the U.S. Army's proposed Interim Brigade Combat Team (BCT) is the Reconnaissance, Surveillance and Target Acquisition (RSTA) Squadron. The fundamental role of the RSTA Squadron is to provide detailed situational understanding to the BCT Commander facilitating freedom of maneuver and the concentration of combat power at the decisive time and place. Technologically advanced systems should substantially enhance RSTA Squadron operations. Among the proposed systems in the Squadron are the Future Scout and Cavalry System (FSCS), tactical unmanned aerial vehicles (TUAV), ground‐based networked sensors (acoustic, seismic, magnetic, infrared, radio frequency), radio frequency (RF) detectors, and nuclear, biological and chemical (NBC) reconnaissance systems. This paper outlines the process used to date for designing the RSTA Squadron and proposes an alternative approach: a systems engineering methodology to formulate, analyze and interpret RSTA Squadron design alternatives.
Aerosol box for intubation of patients with suspected COVID-19: simulation study

Introduction. Endotracheal intubation is a procedure associated with a high level of exposure to the COVID-19 virus. This has led to the search of alternatives to reduce the risk of contamination, including the so-called aerosol box. Objective: To compare time and difficulty of orotracheal intubation when using the aerosol box in a simulated setting. Methodology: Observational study conducted with the participation of 33 anesthetist physicians and anesthesia residents; groups were compared in terms of time and intubation difficulty using a conventional Macintosh laryngoscope and the McGRATH™ MAC (Medtronic) videolaryngoscope with or without aerosol box. In order to determine performance with the intubation maneuver, crude hazard ratios were estimated, and a Cox multivariate regression model was built, adjusted by anesthetist years of experience and difficulties during the procedure. Results: On average, the aerosol box increased intubation time by 7.57 seconds (SD 8.33) when the videolaryngoscope was used, and by 6.62 (SD 5.74) with the Macintosh. Overall, 132 intubations were performed, with 121 successful and 6 failed first-time attempts (4 with the use of the aerosol box); 16 participants (48.48%) reported difficulty handling the box. With the use of the Macintosh, intubation was found to be faster than with the videolaryngoscope (cHR: 1.36 [95% CI 0.64-2.88]; adjusted HR: 2.20 [95% CI 0.73-6.62]). Conclusions: The use of the aerosol box and personal protective equipment in a simulation setting hinders the intubation maneuver and may result in protracted execution time.
Optimal Outside Air Control for Air Handling Units with Humidity Control

Most air handling units (AHUs) in commercial buildings have the (air) economizer cycle to use outside air for free cooling under certain outside air conditions. Ideally the economizer cycle is enabled if outside air enthalpy is less than return air enthalpy. During the economizer cycle, outside air flow is modulated to seek mixed air temperature at a supply air temperature set point. Since the outside air may be dry during the economizer cycle, humidification is required for AHUs with humidity control. As a result, the economizer cycle saves cooling energy but requires excessive steam for humidification. Therefore the economizer cycle may not be economical. An optimal outside air control method is developed to minimize the total cost of mechanical cooling and steam humidification. The impacts of chilled water price, steam price, and space minimum humidity set point are analyzed. Finally the optimal outside air control zones are presented on a psychrometric chart under differential energy price ratios and minimum indoor humidity set points.
The effects of table material on radiated field strength measurement reproducibility at open area test sites

Radiated field strength measurements at open area test sites (OATS) require a nonconductive table to support the equipment under test (EUT). Broadband field strength measurements were performed using tabletops of different materials and thicknesses to investigate the influence of the dielectric properties on the measured field strength. Differences of 10 dB were recorded between fibreglass and wood. Significant differences were also recorded for different woods. It is shown that the differences in the dielectric materials used for the OATS table adversely affect measurement reproducibility between test sites. It is recommended that the dielectric properties of the EUT tabletop be adequately defined in the standards.
A Si-based suspended tunnel structure with trapezoidal section by two-step etching

A two-step etching method is used to prepare a Si-based suspended tunnel structure with a trapezoidal section. In the first wet etching, surfactant Triton-X-100 is added to tetramethylammonium hydroxide (TMAH) enchant to inhibit crystal plane characteristics. Bulk Si Rib with trapezoidal cross section is formed, with inclination of side and height being modulated by changing etching time, to obtain good stability. After the SiO2 support layer is grown by thermal oxidation, pure 25% TMAH is used in the second wet etching to quickly lateral etch and undercut the bulk silicon under the support layer and form a suspended structure along <100> opening. Using additive-no additive two-step etching method, suspended structure with high stability and compressive strength, good insulation characteristics, high yield can be prepared. It lays a solid foundation for developing high sensitivity photo, thermal, chemical and gas sensors.
Cause and Effects of Human-Wildlife Conflict in Ethiopia: A Review

Biodiversity is constantly changing over different scales due to the turnover of biological units across all spatial and temporal scales. The objective of this term paper is through undertaking a systematic review to demonstrate the distribution of biodiversity at different spatial and temporal scales on species component of biological diversity of better-known plant, animal species, microorganism and ecosystem diversity and factors affecting the distribution of biodiversity. Biodiversity is best defined by patterns we see in the world around us and these patterns are the raw material for understanding biological diversity. The distribution of biodiversity is not uniform throughout the world but shows a rather uneven distribution. So that, species diversity decreases as we move away from the equator towards the poles. These indicate that, in the tropical region, unlike temperate ones, there is more solar energy, water availability, and a relatively more constant and predictable environment. The distribution of biodiversity is influenced by a large number of environmental factors, such as the geological history of the area, environmental stability, ecosystem productivity, habitat heterogeneity and suitability, competition, and predation. Therefore, the understanding of the spatial and temporal distribution of biodiversity are urgently required to formulate short and long term resource management strategies as well as biodiversity education and training activities are superior in disseminating innovative techniques and also sustainable use of biodiversity, building local capacity and increasing public understanding for biodiversity management can contribute to overcoming these rapidly changing.
Hand Vein Recognition Based on Improved Template Matching

An improved template-construction method for hand vein recognition is presented. The accomplishment of the new algorithm involves several steps. First, we design the power- controlled multispectral vein acquisition handset to establish high-quality hand vein database. Second, we propose an improved valley-shaped enhancement operator with NiBlack algorithm to realize vein segmentation. Third, we get a basic-shaped template after dilation and erosion operation in the four neighborhoods firstly, and then we can get the final matching template combining all the shapes after the process of filling the connected region whose threshold is smaller than the one we set according to the experiment effect. Finally we design the hand vein recognition experiments using the designed template and traditional template respectively. The recognition rate of the improved template is 96.6% under the 1:1 mode and 95.75% under the 1:N mode while the recognition rate of the traditional template is 89.2% under the 1:1mode and 88.2% under the 1:N mode.
An Integrated Temperature Compensation Method for Thermal Expansion-based Angular Motion Sensors

In this work, we present an integrated ambient temperature compensation method for a thermal expansion- based angular motion (TEAM) sensor system based on both theoretical analysis and experimental investigations. The theoretical study using the extended 2D model indicates that the sensor sensitivity is susceptible to the thermal properties of the working fluid which can be affected by the ambient temperature (Ta). Moreover, the temperature compensation algorithm with the consideration of the working fluid’s thermal properties (Compensation I) was predicted by our model, for the first time, and applied to effectively compensating the sensitivity variation of the TEAM sensor. The sensor in the experiments show a competitive sensitivity of 0.6434mV/°/s compared with the reported thermal-based angular motion sensors. Besides, the experimental compensation results of the TEAM sensor at different ambient temperatures of 25.1°C~50°C revealed an excellent temperature-insensitive output with the maximum variation (δmax) of 1.88% and the temperature drift of sensitivity (TDS) of 591ppm/°C, in comparison with Compensation II without considering the thermal properties (δmax = 20.37%) and the uncompensated counterpart (δmax = 36.28%).
After the Plans: Methods to Evaluate the Implementation Success of Plans

In light of the continuing and ever-stronger attacks on the legitimacy of the planning profession, planning scholars have recently been calling for quantitative studies that support the notion that planning matters. What is needed are methodologies that can be used by planners to assess the degree of impact their plans have had on actual urban development and, perhaps more important, on the achievement of planning goals. Such methods would differ from existing evaluation research in that the focus would be on assessing what has in fact occurred in the built environment, rather than on evaluating various plan alternatives before implementation. In this paper, I outline various plan assessment methods that delineate how one particular aspect of plans-identifying where public facilities are to be located—can be evaluated.
Reduced Complexity FSD Algorithm for MIMO Detection

Detection is a major challenge for the utilization of multiple-input multiple-output (MIMO) system. Even the fixed sphere decoding (FSD), which is known for its simplicity in calculation, requests too much computation in high order modulation and large number antenna system especially for mobile battery-operated devices. In this paper, a reduced FSD algorithm is proposed to simplify the calculation complexity of the FSD while maintaining the performance at the same time. Simulation results in a 4×4, 16-QAM system show that up to 89% calculation can be saved while the performance drop is less than 0.1dB when SNR=24.
Coarse-grained tight-binding models

Calculating the electronic structure of systems involving very different length scales presents a challenge. Empirical atomistic descriptions such as pseudopotentials or tight-binding models allow one to calculate the effects of atomic placements, but the computational burden increases rapidly with the size of the system, limiting the ability to treat weakly bound extended electronic states. Here we propose a new method to connect atomistic and quasi-continuous models, thus speeding up tight-binding calculations for large systems. We divide a structure into blocks consisting of several unit cells which we diagonalize individually. We then construct a tight-binding Hamiltonian for the full structure using a truncated basis for the blocks, ignoring states having large energy eigenvalues and retaining states with energies close to the band edge energies. A numerical test using a GaAs/AlAs quantum well shows the computation time can be decreased to less than 5% of the full calculation with errors of less than 1%. We give data for the trade-offs between computing time and loss of accuracy. We also tested calculations of the density of states for a GaAs/AlAs quantum well and find a ten times speedup without much loss in accuracy.
