Dual priority: a real-time and integrated, device-and-network-centric wireless network selection

Over the last 5–7 years, with the proliferation of mobile computing devices, there has been a tremendous increase in data usage by mobile subscribers. This has quite often resulted in network congestion, forcing the operators to either increase the available bandwidth or reduce the data-rate per subscriber. To overcome this problem, network operators have been deploying different radio access networks, including Wi-Fi and small cells across their coverage areas. In order to remain always best connected, several techniques have been proposed over the period for efficient network selection. All these techniques can be broadly categorised into either device-centric or network-centric solutions. However, both device-centric and network-centric solutions have their disadvantages. In this study, a ‘dual priority’ scheme is proposed and developed that takes into account the preferences of both the subscribers and the network operator. Notably, the proposed ‘dual priority’ scheme offers a combined decision for the efficient handover of subscribers from cellular to Wi-Fi. In this work, every device has its own mechanism of ranking its preferred networks, after which the network takes the decision for offload based on the preferences and its resource availability. It has been observed that the proposed dual priority scheme results in up-to three times reduction in the time taken for offloading decision as compared to state-of-the-art network-centric solutions.
Development of EST-derived SSR markers in pea (Pisum sativum) and their potential utility for genetic mapping and transferability

With 1 figure and 3 tables ABSTRACT: Simple sequence repeats (SSRs) derived from expressed sequence tags (ESTs) are important resources for gene discovery and mapping. In this study, we developed ESTâbased SSR (eSSRs) markers and assessed their ability in mapping and transferability. A total of 10â800 unigenes were detected from 18â522 pea EST sequences (December 2009). Screening of 10â800 unigenes by MISA (MIcroSAtellite) revealed 2612 (14.1%) eSSRs in 2395 (12.9%) SSRâcontaining ESTs from which 577 (24.1%) primer pairs were designed. The most abundant repeat motif identified in eSSR was mononucleotide (85.2%), followed by trinucleotide (10.6%) and dinucleotide (2.8%). Among 108 randomly selected primer pairs, 40 were assessed for mapping and 68 to test crossâspecies transferability in six leguminous species. Out of 40 primer pairs, 85% produced amplicons, 60% showed polymorphism and 47.5% were mapped. Furthermore, 68 primer pairs revealed high rate of transferability (48â85%) in leguminous species. High levels of polymorphism, reproducibility, presence of alleles (3.8/locus) and transferability revealed the potential use of these eSSR markers in molecular mapping, quantitative trait loci (QTL) analysis and comparative mapping in pea and other legumes.
A near-surface, daytime occurrence of two mesopelagic fish species (Stenobrachius leucopsarus and Leuroglossus schmidti) in a glacial fjord

The northern lampfish (Stenobrachius leucopsarus, family Myctophidae) and northern smoothtongue (Leuroglossus schmidti, family Bathylagidae) are mesopelagic fishes, defined by their vertical distribution in the mesopelagic zone (200–1000 m) during daylight hours. Northern lampfish range from the Bering Sea to southern California (Shimada, 1948), where their abundance is highest along the continental slope and decreases over the continental shelf. They are the most abundant species in the mesopelagic zone of the Bering Sea (Pearcy et al., 1977; Sobolevsky et al., 1996), the Gulf of Alaska (Purcell, 1996), and the eastern North Pacific Ocean off Oregon (Pearcy, 1964; Pearcy et al., 1977). Northern smoothtongue also concentrate in areas bordering the continental slope and are widely distributed from southern British Columbia to the Bering Sea (Peden, 1981) and are very abundant in the Okhotsk Sea (Sobolevsky et al., 1996).
Methionine synthase polymorphisms frequencies distribution in the Jordanian population

Abstract The main purpose of this study was to determine the frequencies distribution of methionine synthase (MTR) (MTR 2756 A > G and MTR 2758 C > G) polymorphisms in the Jordanian population. The frequencies of these polymorphisms were determined in a sample of 491 individuals (males were 270 and females were 221) collected from all the Jordanian regions, which is a good representation of the Jordanian population. The different alleles and genotypes at the two polymorphic sites were identified using the polymerase chain reaction-restriction fragment length polymorphism polymerase chain reaction restriction fragment length polymorphism analysis. Results showed that the overall percentages in the whole Jordanian population were 90.73% and 9.27% for the MTR 2756 A and MTR 2756 G alleles respectively. Only the wild type allele (C) of the MTR 2758 C > G polymorphism was detected. In addition, the association of MTR 2756 A > G and MTR 2758 C > G polymorphisms with the development of neural tube defects (NTDs) was examined using 17 cases of mothers from the Northern part of Jordan who gave birth to NTD affected children during the period of this study. Results showed no association between these two examined polymorphisms and the increase in maternal risk for giving birth to NTD children. The results in this study recommend that more examination should be done on larger populations to make good conclusion, also more studies on gene-gene interaction should be done to examine the associations with NTDs.

Could More Holistic Policy Addressing Classroom Discipline Help Mitigate Teacher Attrition?

Schools across America are losing teachers at an alarming rate. Changing workforce demographics forecasted some level of loss decades ago. More recently, however, it has been noted declines are now reaching a crisis level across parts of the United States for a variety of reasons. Today the prevailing professional literature addressing public education largely identifies financial limitations as the primary force behind these teacher shortages. Research has only recently started to include other alternative factors such as working conditions and personal satisfaction in the conversation surrounding potential reasons for the ongoing loss of teachers. This article introduces findings from a newly completed study in Arizona that confirmed classroom conditions, and most notably student discipline concerns, appear to be important considerations for teachers who are contemplating leaving their current positions. These findings contribute to the scope of the existing literature. They also advance practical implications about implementing initiatives to advance school improvement and in particular to combat teacher attrition. Finally, the article advances possible policy considerations and modifications in professional practice that could be targeted to improve classroom climate and contribute to teacher recruitment and retention successes.
The Influence of Presumed Fake News Influence: Examining Public Support for Corporate Corrective Response, Media Literacy Interventions, and Governmental Regulation

ABSTRACT In today’s society with polarized opinions, fake news has significantly affected people’s trust in online news. Informed by the third-person effect (TPE) and influence of presumed influence (IPI) theories, this study examined atheoretical model to understand the antecedents and consequences of the presumed effects of fake news on others (PFNE3). Data were collected from 661 respondents through survey research based on fake news about acompany shared on Facebook. Results showed the significant impacts of self-efficacy, social undesirability, and consumer involvement on PFNE3. Furthermore, PFNE3 positively predicted public support for corporate corrective actions, media literacy interventions, and governmental regulation. Findings demonstrated the mediating role of PFNE3 in the model. Theoretical and practical implications were discussed.
Identification of novel QTL for resistance to crown rot in the doubled haploid wheat population 'W21MMT70' x 'Mendos'

Crown rot (causal agent Fusarium pseudograminearum) is a fungal disease of major significance to wheat cultivation in Australia. A doubled haploid wheat population was produced from a cross between line 'W21MMT70', which displays partial seedling and adult plant (field) resistance to crown rot, and 'Mendos', which is moderately susceptible in seedling tests but partially resistant in field trials. Bulked segregant analysis (BSA) based on seedling trial data did not reveal markers for crown rot resistance. A framework map was produced consisting of 128 microsatellite markers, four phenotypic markers, and one sequence tagged site marker. To this map 331 previously screened AFLP markers were then added. Three quantitative trait loci (QTL) were identified with composite interval mapping across all of the three seedling trials conducted. These QTL are located on chromosomes 2B, 2D and 5D. The 2D and 5D QTL are inherited from the line 'W21MMT70', whereas the 2B QTL is inherited from 'Mendos'. These loci are different from those associated with crown rot resistance in other wheat populations that have been examined, and may represent an opportunity for pyramiding QTL to provide more durable resistance to crown rot.
The effect of family control on audit fees during financial crisis

Purpose - The purpose of this study is to empirically examine the effect of family involvement in ownership, management and directorship on audit fees during the crisis and non-crisis periods. Design/methodology/approach - Following Anderson and Reeb (2003), this paper uses a two-way fixed effect model to examine the impact of family control on audit fees in crisis and non-crisis periods. The fixed effects include dummy variables for each year and each industry code in the sample. Findings - This paper finds that during normal economic periods, family firms pay lower audit fees relative to non-family firms because of the incentive alignment or monitoring effect. While, during crisis periods, family firms pay higher audit fees because of the shareholder expropriation effect. Research limitations/implications - The results reported in this paper have both practical and policy implications for the demand and supply of audit services to firms having different ownership structures. Originality/value - This is the first study of its kind to examine the effect of family ownership and involvement on audit fees during the crisis period.
Using Mobile Donation to Promote International Fundraising: A Situational Technology Acceptance Model

ABSTRACT As donation through mobile devices becomes globally available, this study aims to promote its adoption and facilitate international fundraising, primarily by examining people’s motivations to make a mobile donation – a donation made by text message. Employing key variables from the situational theory of problem solving and the technology acceptance model, this study proposes an emerging Situational Technology Acceptance Model (STAM). A nationwide survey of 994 American respondents in Spring 2016 and a two-step structural equation modeling process empirically supported STAM. By digging into the nuances of people’s situational motivations to solve a problem and their attitudes toward using a new technology, STAM found that the respondents’ donation intentions were more associated with their technological attitudes. Finally, this study uses awareness of mobile donation and mobile donation intention as two dimensions to segment mobile phone users to active, aware, latent, and non-publics, and offers practical advice for nonprofits to better target their fundraising efforts.
Inhibition and excitation shape activity selection: effect of oscillations in a decision-making circuit

Decision-making is a complex task and requires adaptive mechanisms that facilitate efficient behaviour. Here, we consider a neural circuit that guides the behaviour of an animal in ongoing binary choice tasks. We adopt an inhibition motif from neural network theory and propose a dynamical system characterized by nonlinear feedback, which links mechanism (the implementation of the neural circuit) and function (increasing reproductive value). A central inhibitory unit influences evidence-integrating excitatory units, which in our terms correspond to motivations competing for selection. We determine the parameter regime where the animal exhibits improved decision-making behaviour, and explain different behavioural outcomes by making the link between bifurcation analysis of the nonlinear neural circuit model and decision-making performance. We find that the animal performs best if it tunes internal parameters of the neural circuit in accordance with the underlying bifurcation structure. In particular, variation of inhibition strength and excitation-over-inhibition ratio have a crucial effect on the decision outcome, by allowing the animal to break decision deadlock and to enter an oscillatory phase that describes its internal motivational state. Our findings indicate that this oscillatory phase may improve the overall performance of the animal in an ongoing foraging task. Our results underpin the importance of an integrated functional and mechanistic study of animal activity selection. Author summary Organisms frequently select activities, which relate to economic, social and perceptual decision-making problems. The choices made may have substantial impact on their lives. In foraging decisions, for example, animals aim at reaching a target intake of nutrients; it is generally believed that a balanced diet improves reproductive success, yet little is known about the underlying mechanisms that integrate nutritional needs within the brain. In our study, we address this coupling between physiological states and a decision-making circuit in the context of foraging decisions. We consider a model animal that has the drive to eat or drink. The motivation to select and perform one of these activities (i.e. eating or drinking), is processed in artificial neuronal units that have access to information on how hungry and thirsty the animal is at the point it makes the decision. We show that inhibitory and excitatory mechanisms in the neural circuit shape ongoing binary decisions, and we reveal under which conditions oscillating motivations may improve the overall performance of the animal. Our results indicate that inefficient or pathological decision-making may originate from suboptimal modulation of excitation and inhibition in the neurobiological network.
Cognitive Theory of Mind Influences Destination Memory: Evidence from Normal Aging and Alzheimer's Disease.

OBJECTIVE Theory of mind and destination memory are social abilities that require processing the attributes of interlocutors. Empirical research has demonstrated a relationship between performance on both abilities in normal aging and Alzheimer's disease (AD). We therefore investigated whether processing attributes of interlocutors would result in better destination memory in AD. METHODS Twenty-six mild AD participants and 28 controls were tested on two occasions. On the first one, participants had to tell proverbs to celebrities' faces. Following that, they decided whether they previously told that proverb to that celebrity or not. The same procedures were repeated on the second occasion; however, after telling the proverbs, participants had to introspect about what the celebrities might think about the proverbs (e.g., "what do you think that the celebrities would think about the proverbs? "). RESULTS Group comparisons showed a beneficial effect of introspection on destination memory in controls (Z = -2.57, p < .05) but not in AD participants (Z = -1.05, p = .29). However, analyzes of individual profiles demonstrated that 15 AD participants demonstrated better destination memory after introspection. CONCLUSIONS Our findings show a beneficial effect of introspection on destination memory in normal aging, and at least in some mild AD cases. Future research should investigate the influence of social cognition on memory in AD and how introspection may provide a potential treatment for AD.
A Low Complexity Near-Optimal Iterative Linear Detector for Massive MIMO in Realistic Radio Channels of 5G Communication Systems

Massive multiple-input multiple-output (M-MIMO) is a substantial pillar in fifth generation (5G) mobile communication systems. Although the maximum likelihood (ML) detector attains the optimum performance, it has an exponential complexity. Linear detectors are one of the substitutions and they are comparatively simple to implement. Unfortunately, they sustain a considerable performance loss in high loaded systems. They also include a matrix inversion which is not hardware-friendly. In addition, if the channel matrix is singular or nearly singular, the system will be classified as an ill-conditioned and hence, the signal cannot be equalized. To defeat the inherent noise enhancement, iterative matrix inversion methods are used in the detectors’ design where approximate matrix inversion is replacing the exact computation. In this paper, we study a linear detector based on iterative matrix inversion methods in realistic radio channels called QUAsi Deterministic RadIo channel GenerAtor (QuaDRiGa) package. Numerical results illustrate that the conjugate-gradient (CG) method is numerically robust and obtains the best performance with lowest number of multiplications. In the QuaDRiGA environment, iterative methods crave large n to obtain a pleasurable performance. This paper also shows that when the ratio between the user antennas and base station (BS) antennas (β) is close to 1, iterative matrix inversion methods are not attaining a good detector’s performance.
Analysis of a Spoke-Array Brushless Dual-Electrical-Port Dual-Mechanical-Port Machine With Reluctance Rotor

A novel brushless dual-electrical-port dual-mechanical-port (BLDD) machine, with spoke-array permanent magnet (PM) outer rotor and reluctance inner rotor is proposed in this article. The BLDD machine can be regarded as the combination of the flux modulation machine and PM synchronous machine (PMSM). Compared to the existing BLDD machine, the PMs of the proposed machine only insert into the outer rotor, hence both torques in two machines can reach their optimal values at the same time. Moreover, the spoke-array PMs with inherent flux-focusing effect can reduce the effective air-gap length of PMSM portion and improve the working flux density, thus increasing the torque density significantly. Besides, the reluctance inner rotor without magnets has the advantages of simple structure and high reliability. The structure and operation principle are introduced. Then, the influences of main parameters including slot/pole combination, split ratio, PM size on torque performance are studied. Next, the proposed BLDD PM machine is compared with the conventional one in terms of air-gap flux density, back electromotive force, magnetic forces, and torque performances. A prototype and test bed are designed and built, and the experimental results verify the analysis results.
Ecological Art Experience: How We Can Gain Experimental Control While Preserving Ecologically Valid Settings and Contexts

One point that definitions of art experience disagree about is whether this kind of experience is qualitatively different from experiences relating to ordinary objects and everyday contexts. Here, we follow an ecological approach that assumes art experience has its own specific quality, which is, not least, determined by typical contexts of art presentation. Practically, we systematically observe typical phenomena of experiencing art in ecologically valid or real-world settings such as museum contexts. Based on evidence gained in this manner, we emulate and implement essential properties of ecological contexts (e.g., free choice of viewing distance and time, large scale of artworks, and exhibition-like context) in controlled laboratory experiments. We found, for instance, that for large-scale paintings by Pollock and Rothko, preferred viewing distances as well as distances inducing the most intense art experiences – including Aesthetic Aha insights – were much larger than typical viewing distances realized in laboratory studies. Following Carbon’s (2019) terminology of measurement strategies of art experience, the combined use of “Path #1” (real-world context) and “Path #2” (mildly controlled, still ecologically valid settings and contexts) enables us to understand and investigate much closer what is really happening when people experience art.
A COMPARATIVE STUDY TO EVALUATE THE RETENTION OF CONVENTIONAL AND CAD/CAM FABRICATED BAR ATTACHMENT IMPLANT SUPPORTED ASSEMBLY (IN VITRO STUDY)

Introduction: The use of implant-supported overdentures is a common approach for treating edentulous mandibles. Retention and stability are provided through attachments; bar attachments being probably the most retentive due to greater mechanical stability and better wear resistance. Micro and macro movement between the retentive surfaces of an attachment during mastication, insertion and removal will lead to wear and decrease of the retentive capacity. Using CAD/CAM technology should produce more precise frameworks with better retention. Objectives: was to compare the retention of different Cobalt Chromium bar attachments fabricated by CAD/CAM technology and conventional methods. Materials and methods: Two bar attachments of different method of fabrication were studied. The bars were divided into two different groups according to whether the bar was fabricated using the conventional method or CAD/CAM technology. The retention provided by each bar was tested using Universal testing machine. The difference in retention was compared between the groups. Results:Data was collected, tabulated and statistically analyzed using the appropriate test. Group 1 needed 32.91N dislodging force. Group 2 needed 62.8N to separate the clip from the bar Conclusions: CAD/CAM fabricated bars showed a significantly higher retentive force in comparison to conventional bars.
