Although the vehicular communications began from the era of the Long Term Evolution (LTE), the strict requirements of the vehicular safety and advanced applications force the academic and industrial communities to continue the topic on the next-generation vehicular communications. In order to realize extremely high reliability and low latency, the frequency spectrum of terahertz (THz) band with ultra-large bandwidth is likely to be one of the candidates at the age of beyond 5th-generation communications (B5G). In this paper, a measurement-validated self-developed ray-tracing (rT) simulator of Beijing Jiaotong University is utilized to characterize the vehicle-to-infrastructure (V2I) channel at 300-308 GHz in highway scenario. Corresponding channel parameters, in line with the standard channel models, are then fed into the quasi deterministic radio channel generator (QuadriGa), which is a 3GPP 38.901 reference implementation. The differences in path loss and root-mean-square (rMS) delay spread between rT and QuadriGa are summarized, respectively. The good agreement in the power domain and the time domain indicates that the channel parameters provided in our work can operate well in the standard channel model. These results can be used to guide the design of the future vehicular communications at the THz band.

CoCrMo biomedical alloys are extensively used in medical implants for their superior biocompatibility and mechanical properties. The present study investigates the relationship between microstructure and corrosion behavior on the building surface (XY-plane) and side surface (YZ-plane) of CoCrMo alloys fabricated by laser powder bed fusion (LPBF). Comprehensive electrochemical tests revealed significant anisotropy in corrosion behavior between the XY and YZ planes due to the microstructure heterogeneity. In the XY-plane, finer grain sizes, higher dislocation densities, longer sub-grain boundaries, and a more extensive distribution of inclusions facilitate the formation and stability of a dense protective film, effectively preventing the intrusion of corrosive media. In contrast, the YZ-plane, characterized by a higher density of melt pool boundaries (MPBs), demonstrated pronounced selective corrosion, particularly within the sub-grain regions and along the MPBs. These insights can guide the optimization of manufacturing processes to enhance corrosion resistance, thereby improving the performance and safety of medical implants by reducing the risk of implant failure due to corrosion-related issues.

This paper presents enhanced coordination between TSOs and dSOs with regard to market related information and data infrastructures that can be developed using a cloud-based approach. The definition of use cases with regard to the levels of portal access is proposed and particular attention is given to the different time and space scales of data that is needed to provide harmonised access. The attributes of the information layer as defined in the Smart Grid Architecture Model (SGAM) are reflected in the formally defined use cases. different access levels are demonstrated via the definition of use cases for a trusted cloud platform by considering harmonised access processes and role-based access control for security.

A photothermal conversion of sol precursor by selective laser sintering (SLS) process has opened a novel patterning way for advanced electronic applications. The SLS process bases on the photo-thermal-chemical effect and features for high precision, fast processing, and room temperature processability without inert gas. Therefore, the effectiveness of the interaction between the nanomaterials and laser has examined on the various conductive metal nanomaterials such as gold, silver, and copper. Although the laser sintering process has shown many achievements on the metal nanomaterials, it has rarely studied for the interaction for the metal oxide nanomaterials. In this study, WOx thin film layer employs the SLS process for post-processing which enables patterning and annealing simultaneously with inducing photochemical redox reaction as well as photothermal effect. The SLS-processed WO3 thin film has shown similar electrochemical performances for the electrochromic application to the thermal annealed WO3 thin film. We have demonstrated a facile and fast fabrication of the electrochromic device (ECd) with the SLS-processed WO3 thin film layer. © 2020, The Authors. All rights reserved.

Capacitive six-degree-of-freedom motion sensing technology has the advantages of fast response, high sensitivity, and excellent temperature independence. Widely applied to inertial measurement units and vector force sensors, it suffers from nonlinearity and crosstalk under the full range of multi-axis loads. This paper, based on a typical capacitive six-axis displacement/angle sensing structure consisting of multiple symmetrically arranged space-variable comb and parallel capacitors, theoretically reveals the nonlinearity and crosstalk mechanism under the full range of multi-axis loads for the conventional capacitance differential equation. Two novel decoupling equations based on the fractional and inverse capacitance differential operations are proposed and derived to realize higher-accuracy decoupling detection. Moreover, the effects of full-range displacement, structural parameters, and parasitic capacitance on the nonlinearity and crosstalk of these three equations are discussed for further improvement. By adopting the inverse capacitance differential equation, the maximum nonlinearity and crosstalk errors of the conventional capacitance calculations can be reduced from 50.02 % and 603.2 %FS (Full Scale) to 0.29 % and 8.78 %FS, respectively. When the maximum full-range displacement is decreased from 2 μm to 0.25 μm, the crosstalk error of 8.78 %FS can be further reduced to 1.49 %FS. The feasible condition circuits schemes for three decoupling equations, as well as the generation mechanism and suppression schemes for parasitic capacitance are discussed. A finite element simulation model based on the mechanical and electrical coupled multi-physic field is also established further to verify the theoretical model in the real world. The simulation results agree well the analytical results. The structure, decoupling equations, condition circuit schematic, and parameter analyses proposed in this paper can provide theoretical guidance for developing single-mass six-axis

The commutation failures seriously threaten the safe operation of hybrid AC/dC grid. Considering that commutation failure occurs only on the inverter side, it is very important to study the voltage controlled current source model of LCC HVdC single terminal measurement information with high equivalent accuracy, which is very important for the practicality of real-time electromagnetic transient simulation of LCC HVdC dynamic phasor model. In order to this problem, this paper further discusses the single terminal equivalent model of LCC HVdC system which does not depend on the measurement information of dC sending end AC system, and explores the estimation method of single terminal fast transient response of complex AC/dC coupling faults induced by AC side fault of LCC HVdC inverter station and participation of dC control separation. The error distribution of single terminal equivalent calculation is quantitatively analyzed to lay a foundation for the follow-up protection and control technology research.

Transition from conventional to digital pathology requires a new category of biomedical informatic infrastructure which could facilitate delicate pathological routine. Pathological diagnoses are sensitive to many external factors and is known to be subjective. Only systems that can meet strict requirements in pathology would be able to run along pathological routines and eventually digitized the area, and the developed platform should comply with existing pathological routines and international standards. Currently, there are a number of available software tools which can perform histopathological tasks including virtual slide viewing, annotating, and basic image analysis, however, none of them can serve as a digital platform for pathology. Here we describe OpenHI2, an enhanced version Open Histopathological Image platform which is capable of supporting all basic pathological tasks and file formats;ready to be deployed in medical institutions on a standard server environment or cloud computing infrastructure. In this paper, we also describe the development decisions for the platform and propose solutions to overcome technical challenges including responsive region retrieval and viewing, virtual slide magnification, recording of diagnostic areas. These factors would promote OpenHI2 be used as a platform for histopathological images in real-world clinical settings. Furthermore, in research, OpenHI2 inherited the annotation functionality from the previous version, thus acquired annotations can be directly utilized by the newly added machine learning module which include popular machine learning models to perform tasks such as histology image classification and segmentation in the same environment. Addition can be made to the platform since each component is modularized and fully documented. OpenHI2 is free, open-source, and available at .

controlling the computer through the hand and eye is a new type human-computer interaction, which overcomes the problem of insufficient flexibility in controlling the traditional computer through the mouse and keyboard. This kind of human-computer interaction is more natural and is an inevitable trend of human-computer interaction in the future. The Kinect based hand-eye positioning system is capable of quickly locating the hand-eye position through depth images and color images, and has a strong real-time performance. Kinect based gesture recognition is widely used in human-computer interaction systems, and the Xbox system developed by Microsoft is the most representative. However, these gesture recognition systems do not pay attention to the problem of finger positioning. From finger positioning point of view, this paper solves the precise position of the finger on the screen by homogeneous coordinate transformation, and realizes a complete set of human-computer interaction system based on hand-eye positioning with simple gesture recognition.
