Wi-Fi-Based Location-Independent Human Activity Recognition with Attention Mechanism Enhanced Method

Wi-Fi-based human activity recognition is emerging as a crucial supporting technology for various applications. Although great success has been achieved for location-dependent recognition tasks, it depends on adequate data collection, which is particularly laborious and time-consuming, being impractical for actual application scenarios. Therefore, mitigating the adverse impact on performance due to location variations with the restricted data samples is still a challenging issue. In this paper, we provide a location-independent human activity recognition approach. Specifically, aiming to adapt the model well across locations with quite limited samples, we propose a Channel–Time–Subcarrier Attention Mechanism (CTS-AM) enhanced few-shot learning method that fulfills the feature representation and recognition tasks. Consequently, the generalization capability of the model is significantly improved. Extensive experiments show that more than 90% average accuracy for location-independent human activity recognition can be achieved when very few samples are available.
Information Technology in Complex Health Services: Organizational Impediments to Successful Technology Transfer and Diffusion FRANK CHARLES GRAY SOUTHON MSC ,P HD, MCOMM ,C HRIS SAUER ,P HD, CHRISTOPHER NOEL GRANT (KIT )D AMPNEY ,M SC ,P HD

Objective: To identify impediments to the successful transfer and implementation of packaged information systems through large, divisionalized health services. Design: A case analysis of the failure of an implementation of a critical application in the Public Health System of the State of New South Wales, Australia, was carried out. This application had been proven in the United States environment. Measurements: Interviews involving over 60 staff at all levels of the service were undertaken by a team of three. The interviews were recorded and analyzed for key themes, and the results were shared and compared to enable a continuing critical assessment. Results: Two components of the transfer of the system were considered: the transfer from a different environment, and the diffusion throughout a large, divisionalized organization. The analyses were based on the Scott - Morton organizational fit framework. In relation to the first, it was found that there was a lack of fit in the business environments and strategies, organizational structures and strategy-structure pairing as well as the management process-roles pairing. The diffusion process experienced problems because of the lack of fit in the strategy - structure, strategy - structure - management processes, and strategy - structure - role relationships. Conclusion: The large-scale developments of integrated health services present great challenges to the efficient and reliable implementation of information technology, especially in large, divisionalized organizations. There is a need to take a more sophisticated approach to understanding the complexities of organizational factors than has traditionally been the case. n J Am Med Inform Assoc. 1997;4:112 - 124.
Multiplexed Genome Editing for Efficient Phenotypic Screening in Zebrafish

Zebrafish are widely used to investigate candidate genes for human diseases. While the emergence of CRISPR-Cas9 technology has revolutionized gene editing, the use of individual guide RNAs limits the efficiency and application of this technology in functional genetics research. Multiplexed genome editing significantly enhances the efficiency and scope of gene editing. Herein, we describe an efficient multiplexed genome editing strategy to generate zebrafish mutants. Following behavioural tests and histological examination, we identified one new candidate gene (tmem183a) for hearing loss. This study provides a robust genetic platform to quickly obtain zebrafish mutants and to identify candidate genes by phenotypic readouts.
The necessity of change – how the fourth industrial revolution urges the entrepreneurs to alter their leadership attributes

Innovation leadership is critical in enhancing a firm’s success in today’s changing markets. This research investigates the changes in entrepreneurial leadership attributes amid the fourth industrial revolution and the fast pace of technological advancement. This research tackles a gap in the current knowledge and reveals interesting outcomes covering the barely researched sub-domain of the fourth industrial revolution and examine how the entrepreneurial leadership should be adjusted for better coping with the current fast-paced technology environment, and how the entrepreneur should adjust the leadership attributes in order to fully exploit the advantages of this revolution and gain a competitive advantage. The content analysis method used for this research utilized written data regarding 23 leaders from 20 companies from the latest 19th century during the first industrial revolution until the current fourth industrial revolution. Results reveal noticeable leadership attributes emphasized in the fourth industrial revolution, such as communication, coaching, innovation, forecasting future, team-builder, and more. Those attributes are in tight correlation with the current novel digital leadership paradigm and the known effects of the fourth industrial revolution on the firms and leaders. Results reveal that current entrepreneurs tend to be open-minded while avoiding rejecting innovation from other firms and are willing to share the experience with the adjacent technology ecosystem.
The Relationship between Dental Fear and Anxiety, General Anxiety/Fear, Sensory Over-Responsivity, and Oral Health Behaviors and Outcomes: A Conceptual Model

Dental fear and anxiety (DFA) is common across the lifespan and represents a barrier to proper oral health behaviors and outcomes. The aim of this study is to present a conceptual model of the relationships between DFA, general anxiety/fear, sensory over-responsivity (SOR), and/or oral health behaviors and outcomes. Two rounds of literature searches were performed using the PubMed database. Included articles examined DFA, general anxiety/fear, SOR, catastrophizing, and/or oral health behaviors and outcomes in typically developing populations across the lifespan. The relationships between the constructs were recorded and organized into a conceptual model. A total of 188 articles were included. The results provided supporting evidence for relationships between DFA and all other constructs included in the model (general anxiety/fear, SOR, poor oral health, irregular dental attendance, dental behavior management problems [DBMP], and need for treatment with pharmacological methods). Additionally, SOR was associated with general anxiety/fear and DBMP; general anxiety/fear was linked to poor oral health, irregular attendance, and DBMP. This model provides a comprehensive view of the relationships between person factors (e.g., general anxiety/fear, SOR, and DFA) and oral health behaviors and outcomes. This is valuable in order to highlight connections between constructs that may be targeted in the development of new interventions to improve oral health behaviors and outcomes as well as the experience of DFA.
Two Decades of Purple Martin Stewardship and Recovery in British Columbia - Successes and Challenges

The western subspecies of the Purple Martin (Progne subis arboricola Behle 1968) is Red-listed (Threatened) in British Columbia, a Candidate Species for listing in Washington and a Species of Special Concern in Oregon and California. These designations were assigned because of severe range-wide population declines in the mid-1900s resulting from ongoing loss of cavity nesting opportunities both in the wild and in cities and severe competition for nest cavities from two introduced bird species, European Starlings (Sturnus vulgaris) and House Sparrows (Passer domesticus). This subspecies has rebounded from 5 known breeding pairs nesting in offshore pilings at 2-3 sites within BC in 1985 to over 300 pairs in 2004, entirely as a result of nest boxes built, erected, monitored and maintained primarily by volunteers at ~ 50 marine coastal locations. In 2004, this recovery program included 26 known occupied nesting colonies and the remaining unoccupied nest box sites distributed throughout the Georgia Basin, involving a total of ~1100 nest boxes. This program could not be maintained over such a large geographic area without ongoing dedication and support of 50-70 volunteer stewards and assistants and support from many local businesses, sponsors and funding organizations. The costs of co-ordinating and implementing the annual nesting colony stewardship program over this large geographic area has involved 2500 hours of volunteer labour and about $10,000 of donated materials and equipment use, as well as student summer employment. Motivation of volunteers was achieved through the use of personal contacts; site visits; ongoing communications via phone, fax and email; brochures; program newsletter; and appreciation awards.
Design of a Hybrid Metal-Plasma Transmit-Array With Beam-Scanning Capabilities

This article presents the complete design of a hybrid metal-plasma transmit-array antenna with beam-scanning capabilities. The antenna operates at 1.07 GHz and consists of an active metallic dipole, a metallic ground plane (GP), and a set of cylindrical plasma discharges arranged in a 2-D lattice. The main lobe of the antenna can be tilted toward different directions simply by turning on/off specific subsets of plasma discharges. Toward this aim, a two-step optimization strategy based on the combination of a particle swarm optimization (PSO) and of a genetic algorithm (GA) is adopted. A realistic model of the antenna has been simulated in CST Microwave Studio. To derive plasma parameters, a prototype plasma discharge has been realized and tested. Each plasma bar included in the numerical setup comprises not only the plasma material, but also the glass envelope and the metallic electrodes used to confine and generate the plasma, respectively. An analysis has been carried out to evaluate the effects of adding the electrically long metallic cables to each discharge needed to ignite and sustain the plasma. The radiation properties of the array can be maintained thanks to the insertion of inductances between the electrodes and the cables. Finally, a sensitivity analysis has been conducted to identify intervals of plasma density and neutral gas pressure within which the beam-scanning capabilities of the antenna remain unaffected.
Parametric Study of Joined-Wing Aircraft Geometry

Light wings with high aspect ratio are the main feature of HALE (High Altitude Long Endurance) aircraft. High-aspect-ratio light wings are well known as very flexible structures that can be modeled with nonlinear beam theories. One way to increase effective stiffness is to use the concept of a joined wing. Joined-wing aircraft are characterized by statically indeterminate structures, i.e. structures with multiple load paths. NATASHA (Nonlinear Aeroelastic Trim And Stability for HALE Aircraft) has been updated so that it is now capable of analyzing joined-wing configurations. This paper offers some validation study of analyzing joined-wing aircraft with NATASHA as well as a parametric study of joined-wing geometry. Effects of the joint position and sweep angle of the aft wing has been studied using NATASHA.
Characterization methodology for copper - droplet losses in slags

A major cause of metal losses in slags is the mechanical entrainment of metal droplets. One important factor is the attachment to solid spinel particles in the slag phase. Consequently, these particles hinder the settling of the metal droplets. In order to improve phase separation it is important to identify the fundamental mechanisms governing this attachment. Two complementary methodologies have been developed to study the tendency of metal droplets to attach to solid spinel particles. In one methodology, the interaction between Cu-alloys and spinel is studied by high temperature contact angle measurements. In the other, the entrainment is studied using a synthetic slag containing spinel solids.
Bacterial and Viral Co-Infection in the Intestine: Competition Scenario and Their Effect on Host Immunity

Bacteria and viruses are both important pathogens causing intestinal infections, and studies on their pathogenic mechanisms tend to focus on one pathogen alone. However, bacterial and viral co-infections occur frequently in clinical settings, and infection by one pathogen can affect the severity of infection by another pathogen, either directly or indirectly. The presence of synergistic or antagonistic effects of two pathogens in co-infection can affect disease progression to varying degrees. The triad of bacterial–viral–gut interactions involves multiple aspects of inflammatory and immune signaling, neuroimmunity, nutritional immunity, and the gut microbiome. In this review, we discussed the different scenarios triggered by different orders of bacterial and viral infections in the gut and summarized the possible mechanisms of synergy or antagonism involved in their co-infection. We also explored the regulatory mechanisms of bacterial–viral co-infection at the host intestinal immune interface from multiple perspectives.
A Dual-Polarized Dual-Band Frequency Selective Rasorber With Selective Transmission Windows

This paper presents a dual-polarization dualtransmission band frequency selective rasorber (FSR) with selective in-band transmission responses. The proposed FSR is a two-tier geometry; the top resistive layer consists of a periodic arrangement of convoluted cross-dipole pattern, whereas the bottom lossless layer comprises three square slots of different sizes. A wide absorption band containing two in-band transmission peaks are obtained from the top layer, and the bottom layer is used to assist the overall absorption response as well as realize highly selective transmission windows. Furthermore, the proposed structure is dual-polarized and has angularly stable characteristic upto 45o incident angle. The geometry has also been analyzed with respect to surface current distributions and parametric variations. The proposed FSR, while simulated, shows two transmission bands at 5.85 GHz and 7.10 GHz with 3.10 dB and 3.90 dB insertion losses, respectively. A wide absorption band having absorptivity more than 80% is achieved around the transmission bands in the frequency ranges of 2.83 to 5.10 GHz, 6.18 to 6.82 GHz, and 7.58 to 9.75 GHz.
TELEMETRY AND RADIO FREQUENCY IDENTIFICATION

Comparison of short-range telemetry and radio frequency identification (RFID) systems reveals that they are based on very similar operating principles. Combining the identification and measurement functions into one transponder sensor offers added value for both RFID and telemetry systems. The presence of a memory (e.g. FRAM) in the transponder, required for ID information, can also be utilized for storing measurement results. For passive transponders low power consumption is one of the main objectives. Wireless power transfer for passive transponder sensors together with above aspects concerning a combined telemetry and identification system are discussed.
Stochastic security‐constrained optimal power flow incorporating preventive and corrective actions

Summary This paper presents a new stochastic security-constrained optimal power flow (SSCOPF) model to capture the uncertainties associated with transmission network failures. In the proposed framework, the uncertainties are modeled explicitly using scenarios and then managed through preventive actions (first-stage decisions) and corrective actions (recourse or second-stage decisions). The suggested model determines the optimal operating point considering the scenario weights, i.e., their probabilities. Both preventive and corrective actions are simultaneously optimized through the proposed SSCOPF approach. To reduce the dimensions of the SSCOPF model for large-scale power systems, an efficient iterative solution method is also presented. The effectiveness of the proposed approach is shown on the well-known IEEE 118-bus and 300-bus test systems. Copyright © 2016 John Wiley & Sons, Ltd.

Removal of Hexavalent Chromium(VI) from Wastewater Using Chitosan-Coated Iron Oxide Nanocomposite Membranes

Chromium is a toxic and carcinogenic heavy metal that originates from various human activities. Therefore, the effective removal of chromium from aqueous solutions is an extremely important global challenge. Herein, we report a chitosan-coated iron oxide nanoparticle immobilized hydrophilic poly(vinylidene) fluoride membrane (Chi@Fe2O3–PVDF) which can potentially be used for efficient removal of hexavalent chromium(VI) by a simple filtration process. Membrane filtration is an easy and efficient method for treating large volumes of water in a short duration. The adsorption experiments were conducted by batch and continuous in-flow systems. The experimental data showed rapid capture of hexavalent chromium (Cr(VI)) which can be explained by the pseudo-second-order kinetic and Langmuir isotherm model. The nanocomposite membrane exhibited high adsorption capacity for Cr(VI) (14.451 mg/g in batch system, 14.104 mg/g in continuous in-flow system). Moreover, its removal efficiency was not changed significantly in the presence of several competing ions, i.e., Cl−, NO3−, SO42−, and PO43−. Consequently, the Chi@Fe2O3-PVDF-based filtration process is expected to show a promising direction and be developed as a practical method for wastewater treatment.
Analysis of Winning Experience and Technical Training Effect of Badminton Match Based on BP Neural Network

Aiming at the improvement of the BP neural network algorithm, the improved BP neural network algorithm is used to analyze the multidimensional attributes of the collected data, and the simulation experiment is carried out to find out our competitive advantages and disadvantages. This paper presents a statistical study on the change of service area, the application of service receiving technology, and the treatment of the third stroke technology in the badminton competition. The innovative contribution of this paper is to explore the differences of double service decision-making of badminton at different levels and form a theoretical mechanism analysis system. The research shows that the relationship between active and passive attack and hitting quality has been dealt with in the game. In training, mastering the basic technical movements of badminton is conducive to improving the technical level of badminton.
Evaluation of Nutritional Status of Haemodialysis Patients Using Malnutrition Inflammation Score

Background: One of the common problems of maintenance dialysis patients is malnutrition especially Protein-Energy Malnutrition (PEM) and several studies have revealed that PEM is associated with increased morbidity, mortality, and impaired quality of life. The aim of this work was to evaluate the nutritional status in hemodialysis patients using malnutrition inflammation score (MIS). Methods: This cross-sectional study was carried out on 100 patients on regular hemodialysis. Patients were classified in to two groups according to MIS status; group A which were well nourished and group B which were malnourished. Patients included were subjected to; through history taking, laboratory investigations [CBC, Blood glucose level, Kidney function, Livre function tests, Lipid profile (cholesterol- triglycerides-HDL-LDL), Sodium-Potassium- phosphorus, C-reactive protein, ESR, Iron study (serum iron-serum ferritin-total iron binding capacity)], malnutrition-inflammation questionnaire and malnutrition-inflammation score. Results: There was a statistically significant difference regarding blood hemoglobin, TIBC, creatinine, sodium, HDL, ESR, and CRP between two groups as they all decreased in group B more than group A, except CRP and ESR, creatinine and HDL they increased in group B more than group A (P value <0.05). Conclusions: It is important to incorporate MIS in the care of hemodialysis patients for early detection of malnutrition and for medical nutrition therapy to optimize patients' nutritional status for better outcomes.
Business Engineering: A Practical Approach to Valuing High-Risk, High-Return Projects Using Real Options

Technologists and engineers endeavor to design and propose leading edge concepts, but the development of these concepts ultimately depends on obtaining funds justified by a business case. Most existing business case tools and methods, which have theirorigins in the conservative banking industry, tend to favor those project concepts that have secure annuity-like returns such as extensions of existing product lines. This tutorial provides engineers with the business case methods and tools to calculate the value of smaller, more risky projects where new technology or markets are involved, and which potentially offer higher returns in the long run. These straightforward methods and tools have been adopted from sophisticated techniques used in the options markets, where investments in risky securities are routinely traded. We first present an example scenario for a new product and review a typical business case using net present value analysis. Next we develop a "what-if" multi-scenario business case model using Monte Carlo simulation. Then we examine an investment decision using a decision tree to capture scenario flexibility. Finally, we determine a risk-averse investment decision using real options calculated with an intuitive and transparent algorithmic tool. In conclusion we show business engineering as a new approach that provides engineers with investment and risk modeling tools and methods that can be incorporated along- side standard systems engineering design modeling techniques to justify the targeting of project investment dollars to manage risk, shape value outcomes, and make better strategic decisions.
Hydropower projects and environmental licensing process: how different countries manages the problem

This research seeks to establish a comparative study among selected countries (Brazil, United States, Canada, Chile and Portugal), regarding aspects of the environmental licensing process for hydroelectric projects. The previous studies consider the Brazilian environmental licensing process to be very complex and differentiated from the other selected countries. There is also a lack of homogeneity among the countries surveyed. In general, environmental licensing is considered a "bottleneck" for the Brazilian electricity sector. With this analysis, it was intended to verify what types of procedures exist in other countries and that could be adopted by Brazil, in order to improve the environmental licensing process of hydroelectric plants. Thus, according to the experience of the countries analyzed, Brazil could improve relations with indigenous peoples and establish a maximum period for finalizing the licensing of hydroelectric plants. Comparative international experiences are important for possible adjustments in the Brazilian licensing process, however, one must not confuse the bureaucracy of the process with excessive simplification.
