Montreal Cognitive Assessment: Normative Data for Cognitively Healthy Swedish 80- to 94-Year-Olds

Background: The Montreal Cognitive Assessment (MoCA) is sensitive to cognitive impairment; however, it is also sensitive to demographic and socio-cultural factors. This necessitates reliable sub-population norms, but these are often lacking for older adults. Objective: To present demographically adjusted regression-based MoCA norms for cognitively healthy Swedish older adults. Methods: A pseudo-random sample of community-dwelling 80- to 94-year-olds, stratified by age and gender, was invited to the study. Initial telephone interviews and medical records searches (n = 218) were conducted to screen for cognitive impairment. N = 181 eligible participants were administered a protocol including the Swedish version of the MoCA and assessments of global cognition (Mini-Mental State Examination, MMSE) and depression (Patient Health Questionnaire-9, PHQ-9). Individuals scoring in the range of possible cognitive impairment on the MMSE or more than mild depression on the PHQ-9 were excluded (n = 23); three discontinued the test-session. Results: Norms were derived from the remaining n = 158. They were evenly distributed by gender, on average 85 years old, and with a mean education of 11 years. MoCA scores were independently influenced by age and education, together explaining 17.2% of the total variance. Higher age and lower education were associated with lower performance and 46% performed below the original cut-off (< 26/30). Conclusion: The negative impact of increasing age on MoCA performance continues linearly into the nineties in normal aging. Demographic factors should be considered when interpreting MoCA performance and a tool for computing demographically corrected standard scores is provided.
Adaptive flow-induced vibration control using distributed sensor/actuator networks with gated recurrent units and genetic algorithms

This work presents a control scheme for wind-induced vibration mitigation for tall buildings based on a gated recurrent unit (GRU) encoder-decoder model which operates using readings from multiple sensors to define a unique system state. The sensors include a distributed network of pressure probes installed on surrounding buildings, accelerometers installed on the principal building, and atmospheric conditions. The encoder-decoder GRU is trained from timeseries sensor readings to construct a unique internal representation (hidden state) of the evolving wind and building conditions. A 1:400-scale aeroelastic building model with motorized plates acting as aerodynamic control surfaces is used in wind tunnel experiments to conduct this study. An online genetic reinforcement learning (GRL) algorithm uses a series of multilayer perceptron (MLP) networks to determine optimum actuator orientations for different flow conditions. The algorithm stores previously discovered solutions in the MLPs sorted by their fitness. The GA operates by obtaining a solution from each of the MLPs and performing GA operations on them to choose the next combination of plate angles to try. A chance also exists for trying completely random plate angles to prevent the GA from stalling. The MLPs are continuously trained during online optimization using findings obtained from new trials. The system eliminates the need for holding wind conditions, which are uncontrollable, constant during online training but still uses a pseudo-random search technique to obtain global optimum solutions. Results show a considerable reduction in building RMS acceleration when compared with a large collection of results with random constant plate angle orientations.
Viral diseases in Indian freshwater and marine water pisciculture

Intensification of aquaculture allows emergent and resurgent viral pathogens to cause large die-offs in the wild and farms. The inherent capability of viruses to exist in multiple forms outside the hosts gives them an edge for easy transmission and translocation increasing the chances of infection. More efforts are needed for an in-depth understanding of viral epidemiology. Quantification of factors determining the virulence mechanisms and variability in disease expression is necessary to strengthen the basic knowledge on virology. The article is an update on the current understanding on viral diseases in fish causing loss to Indian aquaculture systems.
Reaction torque feedback based vibration control in multi-degrees of freedom motion system

This paper presents a position control method in a multi-degrees of freedom flexible manipulator. For the control of the flexible manipulator, it is easy to construct the controller in each joint. In practical application, however, the workspace is preferred to the joint space for position control of the multi-degrees of freedom manipulator. This paper shows a novel control strategy of the flexible manipulator in the workspace. First, to suppress the vibration of the arm, the proposed approach introduces the feedback of reaction torque. Second, the controller includes a displacement feedback caused by the elastic deformation of the arm to increase the response speed. The combination of the reaction torque feedback in the joint space and the displacement feedback brings the stable and robust position control in a multi-degrees of freedom flexible manipulator. The effectiveness of the proposed method is confirmed by several experiments.
An Examination of Affiliate and Network Television Channels’ Facebook Use for Addressing Audiences’ Critical Information Needs

Based on the principles of localism and Critical Information Needs (CIN), this study analyzed the news content posted on Facebook by three television news channels—one local ABC affiliate each in Phoenix, Arizona and Kearney, Nebraska, and ABC News network channel — to examine the extent to which these posts fulfilled the critical information needs of audiences via social media. Results showed the local channel in Phoenix posted more CIN content than both, national network ABC and the local television channel in Kearney. Audience engagement with CIN posts differed across communities, with some categories increasing engagement in Phoenix and the same categories decreasing engagement in Kearney. This finding highlights not all critical information posts lead to increased audience engagement on social media and it is important for television channels to pay attention to content format and user feedback to further increase audience engagement with critical information.

Abstract This study focuses on the level of mobilizing fun-inspired pedagogical knowledge and leadership practices among Malaysian public preschool teachers for effective teaching of fundamental science concepts that suit the current education ecosystem. Descriptive statistics were employed to analyze the survey data. A total of 242 teachers from 220 public preschools in Malaysia took part in the survey. The analysis revealed ten commonly applied fun-based strategies and techniques ranging from the most commonly applied to the least applied strategies and techniques namely, singing; experiments; storytelling; demonstrations; game-based learning; project-based learning; YouTube videos; asking probing questions; observations; and simulations. Most of the respondents are proficient in applying the ten strategies and techniques, with 50.41 percent for singing; 49.59 percent for experiments; 48.39 percent for storytelling; 47.93 percent for demonstrations; 47.10 percent for game-based learning; 46.28 percent for project-based learning; 45.87 percent for YouTube videos; 45.45 percent for asking probing questions; 43.39 percent for observations; and 42.56 percent for simulations. The result also indicated that most of the respondents are proficient or extremely proficient in leading their peer teachers for effective teaching of fundamental science concepts ranging from 39.67 percent to 53.72 percent of respondents proficient, followed by 35.53 percent to 57.02 percent of respondents extremely proficient in leading their peer teachers on fun-inspired pedagogy. The findings indicate that a promising innovative module is needed to guide preschool teachers to boost their creativity in designing and planning varieties of inspirational, innovative, creative, and interactive activities that suit the new realm. The result also indicates that it is significant to shift the paradigm from isolation to collaboration, and from in-person to online interactions. It is also significant to mobilize peers’ leadership competencies that suit Education 4.0 in Malaysia.
Cross-Validation of Multiple WAIS-IV Digit Span Embedded Performance Validity Indices Among a Large Sample of Adult Attention Deficit/Hyperactivity Disorder Clinical Referrals

This study investigated the utility of four WAIS-IV Digit Span (DS) indices (traditional Reliable Digit Span [RDS], RDS-Working Memory [RDS-WM], RDS-Revised [RDS-R], and DS Age-Corrected Scaled Score [ACSS]) as embedded performance validity tests (PVTs) among a sample of 342 consecutive adults referred for neuropsychological evaluation of ADHD. All DS indices had acceptable classification accuracy (areas under the curve: .73–.76) for detecting invalid performance with optimal cut-scores of RDS ≤7 (35% sensitivity/93% specificity), RDS-WM ≤7 (56% sensitivity/86% specificity), RDS-R ≤12 (48% sensitivity/85% specificity), and ACSS ≤7 (46% sensitivity/87% specificity). Although all indices were able to detect invalid performance, DS indices incorporating the more complex working memory trials of the task yielded the best accuracy for identification of invalid test performance among adults referred for ADHD evaluation.
BGP Control Plane for NSH SFC

This document describes the use of BGP as a control plane for networks that support Service Function Chaining (SFC). The document introduces a new BGP address family called the SFC AFI/SAFI with two route types. One route type is originated by a node to advertise that it hosts a particular instance of a specified service function. This route type also provides "instructions" on how to send a packet to the hosting node in a way that indicates that the service function has to be applied to the packet. The other route type is used by a Controller to advertise the paths of "chains" of service functions, and to give a unique designator to each such path so that they can be used in conjunction with the Network Service Header defined in RFC 8300. This document adopts the SFC architecture described in RFC 7665.
Effects of Innovative Processing Methods on Microalgae Cell Wall: Prospects towards Digestibility of Protein-Rich Biomass

Microalgae are known to have higher photosynthetic efficiencies when compared to land-based plants. The use of microalgae biomass as a protein source is attracting attention due to its interesting protein composition and sustainable character when compared to conventional animal and plant protein-based sources. Nonetheless, the existence of a rigid cell wall is typical for most microalgae species, and this presents a serious obstacle to a higher bioaccessibility of their valuable protein fractions. Depending on the cell wall composition, the gastrointestinal digestion process itself can result in different pathways of protein absorption. It is then important to understand how microalgae cell wall structure can be affected during traditional and industrial production of its biomass once these questions are often overlooked. This review intends to fulfill this gap by addressing the major impacts of innovative sustainable processing of microalgae biomass, giving particular attention to drying operations and cellular disruption methods based on electric field application—such as pulsed electric fields (PEF) and moderate electric fields (MEF). Using microalgae biomass as food supplements at its full potential depends on its protein digestibility patterns, and subsequently their bioaccessibility and bioavailability. The importance of using in vitro gastrointestinal systems to understand the impact of innovative downstream processing of microalgae biomass will be addressed.
Dynamic modeling of a four-phase 8/6 switched reluctance motor using current and torque look-up tables

The paper presents dynamic modeling of a commercially available 1-hp 4-phase 8/6 switched reluctance motor (SRM) using nonlinear 2D look-up tables created from its measured flux linkage and static torque data. A model for each phase consists of a flux linkage estimator, a current look-up table and a torque look-up table. The current look-up table was achieved for 101 data of flux linkage (from 0 to 0.275 Wb/spl middot/t) by 115 rotor positions (from -30/spl deg/ to 30/spl deg/). Besides, the torque lookup table was achieved for 14 data of current from (0 to 6.5 A) by 115 rotor positions (from -30/spl deg/ to 30/spl deg/). The machine model was then tested in Matlab/Simulink environment and also experimentally verified. An asymmetric half-bridge converter, which was driven by DS1102 DSP real-time control environment, applied single-step voltage, single-pulse control voltage and current-regulated PWM voltage to the motor windings. The agreement between simulation and experimental results has confirmed the accuracy of the proposed model.
WHAT IS BEAMFORMING

Beamforming is an imaging technique that has found many applications in aeroacoustics, and continues to evolve to meet greater challenges. It has elements in common with other methods such as nearfield acoustic holography, but its strength is distributed, broadband, incoherent sources at arbitrary distance from the array. The formulation of the classical technique in the frequency domain is simple and lends itself to many types of analysis. A derivation is given here that leads to an expression for the variance of the beamform map when the integration time is finite and not all of the elements of the cross spectral matrix are included.
iCare—supporting people with increased need for care with smart and mobile IT

The recent developments in the area of mobile computing have fueled the debate on potential applications for independent living, well-being and medical interventions both in the academic field and in practice. A considerable amount of research and development of IT-based assistance systems is focused on clinical applications. However, assistance systems that can be used in everyday life by a broad user group of people with increased need for care are rare. In this paper we present the vision of iCare—a research program to support a safe and independent living of people with special needs. In addition, we exemplarily introduce DeSearch—a privacy-aware sensor-based network to locate missing people—as a first result of iCare.
Data-Driven Optimization for Dynamic Shortest Path Problem Considering Traffic Safety

Traffic congestion is an inescapable problem that frustrates drivers in megacities. Although there is hardly a way to eliminate the congestion, it is possible to mitigate the impact through predictive methods. This paper develops a data-driven optimization approach for the dynamic shortest path problems (DSPP), considering traffic safety for urban navigations. The dynamic risk scores and travel times at different times and locations are estimated by the Safe Route Mapping (SRM) methodology and Long Short-Term Memory (LSTM) with Autoencoder, respectively, where possible variations in the future are considered. The DSPP is formulated as a mixed-integer linear programming problem under risk constraints to minimize the total travel cost, defined as the weighted sum of distance and travel time. To improve the efficiency of the DSPP, we design an improved tabu search with alternative initial-solution algorithms to accommodate various problem scales. Moreover, subgraph and self-adaptive insertion techniques are adopted as acceleration strategies to enhance computational efficiency further. Numerical experiments investigate the computational performance and the solution quality of our algorithm. The result shows satisfactory solution quality and computational efficiency with the proposed acceleration strategies compared to the CPLEX solver, a label-setting algorithm, and a state-of-the-art algorithm. Our algorithm can also compete with Google Maps regarding the travel cost in a real network in Manhattan, NY, USA, which is promising for Urban Navigations.
Further advances in the diagnosis and treatment of Leber’s Hereditary Optic Neuropathy – a review

Leber’s Hereditary Optic Neuropathy (LHON), is one of the most frequent mitochondrial diseases characterized by Retinal Ganglion Cells degeneration. Pathogenic gene mutations in LHON induces mitochondrial impairment, which in turn leads to insufficient mitochondrial ATP production. The pathologic hallmark of the disease is primary degeneration of retinal ganglion cells, which results in optic nerve atrophy. The paper reviews some of the recent advances in the understanding of LHON: new genetics discoveries and novel therapeutic approaches.
Opportunity or risk? Mobile phones and the social inclusion gap among people with visual impairments

Abstract Mobile phones have been regarded as an enabler that reduces barriers in a disabling environment. Therefore, disability research has focused on the social inclusion consequences of this technology. Adopting the uses and gratifications approach, this study examines the correlation between access to mobile phones and the social participation and social relationships of people with visual impairment. This study conducts a survey and demonstrates that mobile phones facilitate the social inclusion of people with visual impairment, while creating a social inclusion gap between people with different degrees of visual impairment and socioeconomic status. Partially sighted people have more possibilities to explore the physical world, while blind people with lower socioeconomic status are restricted to the digital space. Therefore, technology could create a new form of digital exclusion and widen the social inclusion gap among people with visual impairment. Points of interest Mobile phones have been regarded as an enabler that reduces barriers in a disabling environment. This study found that mobile phones can provide opportunities for people with visual impairment, while posing potential risks. The use of and gratification associated with mobile phones affect the social inclusion outcomes of people with visual impairment. However, they may also create social inclusion gaps between people with different degrees of visual impairment and socioeconomic status. Partially sighted people have more possibilities to explore the physical world, while blind people with lower socioeconomic status may be restricted to the digital space created by technology. Technology carries some risks of creating a new form of digital exclusion and widening the social inclusion gap among people with visual impairment.
Pentingkah Perilaku Wanita? Studi Kebijakan Dividen

Board diversity in the corporate governance function have multiple perspectives and active oversight in evaluating management decisions and through their influence on dividend policy. Therefore, this study examines the effect of female boards on the dividend payout ratio and dividend yield in a sample of companies in the IDX HIDIV20 and IDX BUMN20 for the period 2017-2020. The results showed that the percentage of female directors, female independent directors, female executive directors, and the numerical number of female directors had a significant positive effect on the dividend payout ratio. Women's associations and dividend policy have a stronger relationship when women on the board of directors have a high percentage. A certain number of women's councils were judged to be better and more effective in decision-making. While the female CEO as a leader because of risk-averse behavior, low self-confidence, weak decisions, and lack of control on the board, affect the value of the company including influencing dividend payments inversely. The results of this study provide strong evidence plus difference test and robustness test confirming that female boards facilitate corporate governance and promote dividend payouts further.
Land–Air–Wall Cross-Domain Robot Based on Gecko Landing Bionic Behavior: System Design, Modeling, and Experiment

Based on the bionic behavior of geckos, this paper presents a land–air–wall cross-domain robot which can fly in air, run on the ground, and adhere to various wall surfaces. When geckos jump and adsorb to vertical surfaces such as trunks, they can still adsorb to the wall with a large contact speed. Inspired by this phenomenon, we analyze the mechanism, apply it to our robot, and optimize the design of the robot structure. In addition, geckos use their tails to adjust posture to achieve abdominal landing during the process of falling. Inspired by this phenomenon, based on the rotor lift/power curve, we optimize the center of gravity by controlling the servo angle. The initial center of gravity offset of the robot is estimated by the extended state observer. The method reduces the distance between the center of gravity and the geometric center, balances the load of each propeller, and finally reduces the total power. The experiment and simulation results validate the feasibility of the land–air–wall cross-domain robot and the bionic methods.
Effects of Torreya grandis Kernel Oil on Lipid Metabolism and Intestinal Flora in C57BL/6J Mice

Background Recent experimental studies have shown that vegetable oil supplementation ameliorates high-fat diet- (HFD-) induced hyperlipidemia and oxidative stress in mice via modulating hepatic lipid metabolism and the composition of the gut microbiota. The aim of this study was to investigate the efficacy of the Torreya grandis kernel oil (TKO) rich in unpolysaturated fatty acid against hyperlipidemia and gain a deep insight into its potential mechanisms. Methods Normal mice were randomly divided into three groups: ND (normal diet), LO (normal diet supplement with 4% TKO), and HO (normal diet supplement with 8% TKO). Hyperlipidemia mice were randomly divided into two groups: HFN (normal diet) and HFO (normal diet supplement with 8% TKO). Blood biochemistry and histomorphology were observed; liver RNA-seq, metabolomics, and gut 16S rRNA were analyzed. Results Continuous supplementation of TKO in normal mice significantly ameliorated serum total cholesterol (TC), triglyceride (TG), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), and free fatty acid (FFA) accumulation, decreased blood glucose and malondialdehyde (MDA), and enhanced superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px) levels. According to GO and Kyoto Encyclopedia of Genes and Genomes (KEGG) analysis, most differentially expressed genes (DEGs) were significantly enriched in the biosynthesis of unsaturated fatty acid pathways, and significantly changed metabolites (SCMs) might be involved in the metabolism of lipids. High-dose TKO improved gut alpha diversity and beta diversity showing that the microbial community compositions of the five groups were different. Conclusion Supplementation of TKO functions in the prevention of hyperlipidemia via regulating hepatic lipid metabolism and enhancing microbiota richness in normal mice. Our study is the first to reveal the mechanism of TKO regulating blood lipid levels by using multiomics and promote further studies on TKO for their biological activity.
