Motor Imagery-Based Brain-Computer Interface Combined with Multimodal Feedback to Promote Upper Limb Motor Function after Stroke: A Preliminary Study

Background Recently, the brain-computer interface (BCI) has seen rapid development, which may promote the recovery of motor function in chronic stroke patients. Methods Twelve stroke patients with severe upper limb and hand motor impairment were enrolled and randomly assigned into two groups: motor imagery (MI)-based BCI training with multimodal feedback (BCI group, n = 7) and classical motor imagery training (control group, n = 5). Motor function and electrophysiology were evaluated before and after the intervention. The Fugl-Meyer assessment-upper extremity (FMA-UE) is the primary outcome measure. Secondary outcome measures include an increase in wrist active extension or surface electromyography (the amplitude and cocontraction of extensor carpi radialis during movement), the action research arm test (ARAT), the motor status scale (MSS), and Barthel index (BI). Time-frequency analysis and power spectral analysis were used to reflect the electroencephalogram (EEG) change before and after the intervention. Results Compared with the baseline, the FMA-UE score increased significantly in the BCI group (p = 0.006). MSS scores improved significantly in both groups, while ARAT did not improve significantly. In addition, before the intervention, all patients could not actively extend their wrists or just had muscle contractions. After the intervention, four patients regained the ability to extend their paretic wrists (two in each group). The amplitude and area under the curve of extensor carpi radialis improved to some extent, but there was no statistical significance between the groups. Conclusion MI-based BCI combined with sensory and visual feedback might improve severe upper limb and hand impairment in chronic stroke patients, showing the potential for application in rehabilitation medicine.
A passive gust alleviation system for light aircraft

A passive aeromechanical gust alleviation system has been examined for application to a Cessna 172. The system employs small auxiliary wings to sense changes in angle of attack and to drive the wing flaps to compensate the resulting incremental lift. The flaps also can be spring loaded to neutralize the effects of variations in dynamic pressure. Conditions for gust alleviation are developed and shown to introduce marginal stability if both vertical and horizontal gusts are compensated. Satisfactory behavior is realized if only vertical gusts are absorbed; however, elevator control is effectively negated by the system. Techniques to couple the elevator and flaps are demonstrated to restore full controllability without sacrifice of gust alleviation.
Investigating Channel Pruning through Structural Redundancy Reduction - A Statistical Study

Most existing channel pruning methods formulate the pruning task from a perspective of inefficiency reduction which iteratively rank and remove the least important filters, or find the set of filters that minimizes some reconstruction errors after pruning. In this work, we investigate the channel pruning from a new perspective with statistical modeling. We hypothesize that the number of filters at a certain layer reflects the level of 'redundancy' in that layer and thus formulate the pruning problem from the aspect of redundancy reduction. Based on both theoretic analysis and empirical studies, we make an important discovery: randomly pruning filters from layers of high redundancy outperforms pruning the least important filters across all layers based on the state-of-the-art ranking criterion. These results advance our understanding of pruning and further testify to the recent findings that the structure of the pruned model plays a key role in the network efficiency as compared to inherited weights.
Integrated driver modelling considering state transition feature for individual adaptation of driver assistance systems

This paper describes the modelling of naturalistic driving behaviour in real-world traffic scenarios, based on driving data collected via an experimental automobile equipped with a continuous sensing drive recorder. This paper focuses on the longitudinal driving situations which are classified into five categories – car following, braking, free following, decelerating and stopping – and are referred to as driving states. Here, the model is assumed to be represented by a state flow diagram. Statistical machine learning of driver–vehicle–environment system model based on driving database is conducted by a discriminative modelling approach called boosting sequential labelling method.
A Study on the Method of Vibration Analysis for Korean High Speed Train by the On-Line Test

The Korean High Speed Train (KHST) has been tested on the Kyongbu high speed line and the Honam conventional line since 2002. A data acquisition system was developed to test and prove the dynamic performance of the KHST, and the system has been found to be very efficient in acquiring multi-channel data from accelerometers located all over the train. Also presented in this paper is an analysis procedure which is simple and efficient in analyzing the acceleration data acquired during the on-line test of the KHST. The understanding of system vibration mode for a railway vehicle is essential to evaluate the characteristics of a dynamic system and to diagnose the dynamic problems of the vehicle system during tests and operations. Methods based on homogeneous linear systems are not realistic because real systems have nonlinear characteristics and are strongly dependent on environmental conditions. In this paper an efficient method of vibration analysis has been proposed and applied for the KHST to evaluate its vibration mode characteristics. The results show that this method is suitable to estimate the system vibration modes of the KHST.
Evaluation of LandscapeDNDC Model Predictions of CO2 and N2O Fluxes from an Oak Forest in SE England

Process-based biogeochemical models are valuable tools to evaluate impacts of environmental or management changes on the greenhouse gas (GHG) balance of forest ecosystems. We evaluated LandscapeDNDC, a process-based model developed to simulate carbon (C), nitrogen (N) and water cycling at ecosystem and regional scales, against eddy covariance and soil chamber measurements of CO2 and N2O fluxes in an 80-year-old deciduous oak forest. We compared two LandscapeDNDC vegetation modules: PSIM (Physiological Simulation Model), which includes the understorey explicitly, and PnET (Photosynthesis–Evapotranspiration Model), which does not. Species parameters for both modules were adjusted to match local measurements. LandscapeDNDC was able to reproduce daily micro-climatic conditions, which serve as input for the vegetation modules. The PSIM and PnET modules reproduced mean annual net CO2 uptake to within 1% and 15% of the measured values by balancing gains and losses in seasonal patterns with respect to measurements, although inter-annual variations were not well reproduced. The PSIM module indicated that the understorey contributed up to 21% to CO2 fluxes. Mean annual soil CO2 fluxes were underestimated by 32% using PnET and overestimated by 26% with PSIM; both modules simulated annual soil N2O fluxes within the measured range but with less interannual variation. Including stand structure information improved the model, but further improvements are required for the model to predict forest GHG balances and their inter-annual variability following climatic or management changes.

Hydrogen Storage Tank Systems and Materials Selection for Transport Applications

The present international socio-economic drive for renewable energy use for sustainable development with environmental protection directs attention to hydrogen as energy carrier. Hydrogen production and storage, and fuel cell (FC) technologies have been intensively worked on in Europe including European Commission (EC) supported projects via Framework Programs (FPs), as well as various national and international cooperative programs including those of International Energy Agency (IEA) and International Partnership for Hydrogen Economy (IPHE). The hydrogen storage is required for transport applications as dense as possible to achieve high gravimetric and volumetric density. The storage of hydrogen in liquid, gas and solid forms are associated with low temperature cooling, higher pressures up to 700 bar and integrated higher volume and weight, respectively. The liquid and pressurized gas storage systems are relatively advanced in present applications. On the other hand, the system safety and reliability, hence the public acceptance as well as economic feasibility have been the main drives for solid and hybrid hydrogen applications. The use of solid hydrogen is predicted by the automotive industry to ultimately dominate the hydrogen transport application market. The bottleneck in solid hydrogen application is metal hydride production to meet the quantitative targets for vehicles mainly following the US DOE goals set for years up to 2015. System requirements need also be met for a present target of e.g. 75kWel fuel cell cars aiming at a 400km driving distance with 4 kg of hydrogen. This necessitates a gravimetric storage density of over 6 wt. per cent. The present paper will address the hydrogen storage tank system for on-board applications including storage tank materials, system design, production technologies and system safety. An overview will be presented on the current state-of-the-art of European and international progress on storage materials integrated into on-board storage tank system. The European current programs on hydrogen storage technologies for transport applications including design, safety and system reliability will be addressed.Copyright © 2006 by ASME

Chloroplast Genome Draft of Dryobalanops aromatica Generated Using Oxford Nanopore Technology and Its Potential Application for Phylogenetic Study

Kapur (Dryobalanops aromatica) is an important dipterocarp species currently classified as vulnerable by the IUCN Red List Threatened Species. Science-based conservation and restoration efforts are needed, which can be supported by new genomic data generated from new technologies, including MinION Oxford Nanopore Technology (ONT). ONT allows affordable long-read DNA sequencing, but this technology is still rarely applied to native Indonesian forest trees. Therefore, this study aimed to generate whole genome datasets through ONT and use part of these data to construct the draft of the chloroplast genome and analyze the universal DNA barcode-based genetic relationships for D. aromatica. The method included DNA isolation, library preparation, sequencing, bioinformatics analysis, and phylogenetic tree construction. Results showed that the DNA sequencing of D. aromatica resulted in 1.55 Gb of long-read DNA sequences from which a partial chloroplast genome (148,856 bp) was successfully constructed. The genetic relationship was analyzed using two selected DNA barcodes (rbcL and matK), and its combination showed that species of the genus Dryobalanops had a close relationship as indicated by adjacent branches between species. The phylogenetic tree of matK and the combination of the matK and rbcL genes showed that D. aromatica was closely related to Dryobalanops rappa, whereas the rbcL gene showed group separation between D. aromatica and D. rappa. Therefore, a combination of the matK and rbcL genes is recommended for future use in the phylogenetic or phylogenomic analysis of D. aromatica.
A Metasurface Beam Combiner Based on the Control of Angular Response

Beam combiners are widely used in various optical applications including optical communication and smart detection, which spatially overlap multiple input beams and integrate a output beam with higher intensity, multiple wavelengths, coherent phase, etc. Since conventional beam combiners consist of various optical components with different working principles depending on the properties of incident light, they are usually bulky and have certain restrictions on the incident light. In recent years, metasurfaces have received much attention and become a rapidly developing research field. Their novel mechanisms and flexible structural design provide a promising way to realize miniaturized and integrated components in optical systems. In this paper, we start from studying the ability of metasurfaces to manipulate the incident wavefront, and then propose a metasurface beam combiner in theory that generates an extraordinary refracted beam based on the principle of phase gradient metasurface. This metasurface combines two monochromatic light incidents at different angles with identical polarization but arbitrary amplitudes and initial phases. The combining efficiency, which is defined as the ratio of the power in the combining direction to the total incident power, is 42.4% at the working wavelength of 980 nm. The simulated results indicate that this proposed method is able to simplify the design of optical combiners, making them miniaturized and integrated for smart optical systems.

specific way without being able to read its value. For example, you can homomorphically encrypt numbers, and perform homomorphic multiplication and homomorphic addition on the encrypted value without decryption. As the HF plays a great role in privacy protection in the current environment, many scholars have also carried out profound studies. Gentry proposed the scheme based on Learn with Error (LWE) [9,10], and carried out a complete proof on its safety, and improved its efficiency to the stage of application. At the same time, the NTRU HF scheme was proposed by Hoffstein et al. [11] combined integer decomposition with a Polynomial ring [12]. López-Alt et al. [13] proposed a scheme, which can support arithmetic operations without the same keys for decryption the ciphertext, called Multi-Key Homomorphic Encryption (MKHE). Moreover, MKHE uses minimal communication costs to make a design for a round-efficient MPC protocol [14]. More and more homomorphism encryption schemes have been proposed. This is a relatively new field, and there are still major issues being addressed. Since ciphertext retention binds the structure of the data after encryption even though it is impossible to read the specific information, it makes it possible to train models on encrypted data.
Application of Three-Parameter Model in Settlement Calculation of Immersed Tube Tunnel

The settlement of immersed tube tunnel is mainly caused by the compression of basal layer and recompression of the ground foundation layer. Defining the composite foundation as a combination of basal layer ofimmerse tube tunnel and ground foundation layer, a three-parameter model is proposed in this study to simulate the composite foundation in which the basal layer was represented using springs and the ground foundation layer by Kelvin’s model. Based on the solution of beam on elastic foundation, analytical solution for settlement of immersed tube tunnel using the proposed three-parameter model was derived by means of Laplace transformation according to the correspondence principle and the constitutional relationship of the three-parameter model. Initial and final settlement as well as variation of settlement in terms of time were calculated and compared with the actual measured data in combination with actual data measured during tunnelling of Shenjiamen immersed tube tunnel in Zhoushan City. Results showed that the proposed three-parameter model is capable of replacing the basal and ground foundation layers. The calculated value matched favourably with the actual measured value and the variation of settlement in terms of time for immerse tube tunnel can be represented.
New directions in burnout research

ABSTRACT Burnout is a phenomenon that has received considerable research attention in the past 50 years. As such, there is advanced knowledge on its prevalence, conceptualization, predictors, and outcomes. Although the literature has advanced, research on burnout is still topical. Burnout originated in the seventies but remains a contemporary problem because of persistent environmental stressors and challenges for employees and organizations as a whole. The current special section aims to stimulate knowledge on unresolved issues by bringing together contributions related to 1) the role of cognition in burnout research, 2) the development of burnout over time, 3) contextual antecedents of burnout, and 4) the prevention of and recovery from burnout. It is our hope that we will see more high-quality research and evidence-based practice related to burnout.
Transformational leadership and quality of work life: A mediation model of trust climate

This study aims to investigate the impact of managers’ transformational leadership on employees’ quality of work life through the mediation effect of firms’ climate of trust in the hospitality industry. The study was conducted with operational employees working in three-star hotels in Bangladesh. Data were gathered from 186 respondents by a structured questionnaire and analyzed by SPSS 21 and SmartPLS 3.0 software. To test the hypothesized model, the study used a partial least squares structural equation model (PLS-SEM) by SmartPLS 3.0. The results of this study revealed the strong direct effects (p &lt; .05) of managers’ transformational leadership (β = 0.433) and firm’s trust climate (β = 0.183) on the employees’ quality of work life with a variance (R2) of 31.9%, and also the significant impact of managers’ transformational leadership (β = 0.599) on firm’s trust climate with a variance (R2) of 35.9%. The study also exposed a significant mediation effect (p &lt; .05) of firms’ climate of trust (β = 0.112) in the relationship between managers’ transformational leadership and employees’ quality of work life. The findings suggest that a trust climate is such an internal mechanism that can convert transformational leadership practices into employee satisfaction with their professional life, while transformational managers can build the climate as well as enrich people’s lives at work.
Effect of Impurities Control on the Crystallization and Densification of Polymer-Derived SiC Fibers

The polymer-derived SiC fibers are mainly used as reinforcing materials for ceramic matrix composites (CMCs) because of their excellent mechanical properties at high temperature. However, decomposition reactions such as release of SiO and CO gases and the formation of pores proceed above 1400 °C because of impurities introduced during the curing process. In this study, polycrystalline SiC fibers were fabricated by applying iodine-curing method and using controlled pyrolysis conditions to investigate crystallization and densification behavior. Oxygen and iodine impurities in amorphous SiC fibers were reduced without pores by diffusion and release to the fiber surface depending on the pyrolysis time. In addition, the reduction of the impurity content had a positive effect on the densification and crystallization of polymer-derived SiC fibers without a sintering aid above the sintering temperature. Consequently, dense Si-Al-C-O polycrystalline fibers containing β-SiC crystal grains of 50~100 nm were easily fabricated through the blending method and controlled pyrolysis conditions.
Suppressing HRRP grating lobes in stepped-frequency train of LFM pulses using extended correlation

Presented is a novel extended correlation method to suppress the grating lobes of the high-resolution range profiles (HRRP) synthesised via the stepped frequency train of LFM pulses (SFT-LFM). By uniformly spacing the nulls of the envelope term to nullify the grating lobes, the method may effectively improve the sidelobe behaviour of SFT-LFM HRRP without loss of the range resolution. Numerical experiments illustrate the effectiveness of the method.
Modified corner-fed dual-polarised stacked patch antenna for micro-base station applications

A modified corner-fed dual-polarised stacked patch antenna, with improved port isolation, is proposed. By shifting the feed points along the lower patch edge and introducing a triangular cut in the middle of another edge, the isolation between the two ports is improved significantly. The proposed antenna achieves a return loss of about 14 dB and a port isolation of more than 28 dB, within the band 2.5–2.7 GHz. The proposed antenna is highly suitable for micro-base station applications in which features such as low profile, low cost and easy fabrication are required.
Manufacturing of Cardiac Models Through Rapid Prototyping Technology for Surgery Planning

Rapid Prototyping (RP) Technology is capable of fabricating 3D freeform solid models from CAD models and has been widely used in communicating design concepts. Due to its distinctive characteristics, RP is very suitable in aiding surgery planning. Typical medical software used to display cardiac images can delineate both inner and outer structure but its images are virtual. Therefore, solid cardiac models made by RP technology provide a touchable reality to compensate for this deficiency. In this research, RP technology is utilized to assist cardiac surgery planning. CT-scanned image data were first processed to obtain RP-acceptable STL file format, and then solid cardiac models were constructed by Objet QuadraTempo, a commercial RP system made in Israel. These models proved extremely helpful in cardiac surgery planning. In addition, several commercial RP systems are compared by their process capabilities for cardiac surgery planning application.
