Digit Bones (Acropodium) of Gazella (Gazella subgutturosa); Three-Dimensional Modelling and Morphometry

The present study was conducted to identify morphometric values and to reveal differences between sexes through three-dimensional modeling of digit bones (ossa phalanges) of gazella by using computed tomography images. A total of 14 (7 female, 7 male) adult gazella (Gazella subgutturosa) cadavers were used in the study. The images were extracted by scanning acropodium bones of gazella at 64-detector Multi Detector Computed Tomography (MDCT) in cross section thickness of 0.625mm. Using MIMICS 20.1 program, three-dimensional models of these images were prepared and morphometric measurements were taken. In GLpe and Bd measurements of Phalanx proximalis, a statistically significant difference was established between females and males in terms of the left forelimb internal, the right forelimb internal, the right forelimb external, and the right hindlimb external bones (P<0.05). There was a statistically significant difference between females and males in terms of volume of phalanx proximalis and surface area of the right forelimb internal phalanx proximalis (P<0.001). In GLpe measurements, a statistically significant difference was determined between females and males in terms of the left forelimb internal, the right forelimb internal, the right hindlimb internal, the left forelimb external, the right forelimb external, and the right hindlimb external phalanx media (P<0.05). A statistically significant difference was determined between females and males in terms of the data related to volume and surface areas of the left hindlimb internal the right hindlimb internal, the left hindlimb external, and the right hindlimb external phalanx distalis (P<0.05).
Post-Quake Small Italian Historical Centres: Urban Resilience between Rhetorics and Reality. The Case Study of Nocera Umbra after the 1997 Umbria-Marche Earthquakes

The small and medium Italian historical centres are characterized, among other things , by reconstruction that have occurred over the centuries after earthquakes. While earthquakes determine structural damages, human losses and loss of the functionality of an urban system above all, they may create, at the same time, new opportunities if the urban and socio-economical structures are improved during the reconstruction processes as a whole. These processes and the optimal implementation of planning models within them is not straightforward [1], due to that several issues emerge as a challenge of the reconstruction programmes (decision-making processes, general vision for the entire urban system for instance). According to the literature, although a unique definition has not still been coined, resilience can be defined as the capacity of a system (a city) to withstand and restore after a shocking episode (an earthquake). Mainly in the context of cities [2], some approaches have been framed and experimented by other authors [3, 4, 5]. Starting from a short literature review, focuses on theories and methodological approaches to evaluate urban resilience, this work analyses – through an interdisciplinary approach – the case study of Nocera Umbra twenty years after two devastating earthquakes occurred in 1997. The research represents a first attempt that aims at analysing if the implemented reconstruction strategies have made the urban system more resilient with respect to both the built and the socio-economic environment.
Adaptive fuzzy fixed‐time tracking control for permanent magnet synchronous motor

This article focuses on the problem of fixed‐time position tracking of permanent magnet synchronous motors with uncertain parameters and load torque disturbance. Based on the fixed‐time stability theory, adaptive control, fuzzy control, and backstepping algorithm, a novel adaptive fuzzy fixed‐time controller is proposed. It is shown that the presented control scheme can guarantee that the tracking errorconverges to a small neighborhood of the zero and all the signals of the close‐loop system are bounded in the fixed‐time. At last, the theoretical analysis and simulation results verify the effectiveness of the developed control strategy.
Educated Nigerian English Phonology as Core of a Regional "RP"

The task of codification and elaboration of the educated varieties of Nigerian English are the ones in current contention among scholars of Nigerian English. Pronunciation issues have however been the bane of Standard Englishes all over the world. While most non-native speakers of English have been able to cross the hurdle of learning the syntax and semantics of Standard English, a recurrent issue in academic discussions has been their inability to approximate the native-like accentual competence. In this paper we have presented submissions of scholars on Nigerian English in comparison with other regional varieties of English belonging to the inner circle. The quality of phonemes in terms of closeness or distance from the prestige, Standard British English, RP has been examined. Considering the close approximation of the phonemic inventory of the Educated Nigerian English model to that of the standard British English, we have found that very few Educated Nigerians use English language effectively. This assessment is made from the perception of how these few Nigerians (i.e. broadcasters) articulate fricatives, affricates, stops or plosives, continuants and central vowels, correctly. The Nigerian RP spoken by this very few ‘educated’ people should qualify to be referred to as a regional RP
Safety of Users in Road Evacuation: Design of Path Choice Models for Emergency Vehicles

Within the framework of the SICURO research project, the main objective of this paper is to define the procedures that were planned and activated in emergencies in order to allow the evacuation of weak users (disabled, old persons, etc.) from the area affected by a disaster and design the optimal path for emergency vehicles to reduce evacuation times. Specification, calibration and validation of a path choice generation model in order to simulate the behavior of emergency vehicle drivers at an urban level during an evacuation is proposed. The authors specify the factors that affect path choice behavior and the two main approaches: one to one and many to one. The first regards the minimization of generalized cost of a path that connects an origin to a destination; the second instead considers the connection of one origin to many destinations. The authors report some experimental results, obtained in the context of the SICURO Project, by applying the proposed model to a real road transport network at urban scale during a simulation of an evacuation.
Fully laminated shell-type three-phase rotating transformer for brushless applications

A fully laminated shell-type three-phase rotating transformer, appropriate for the most brushless applications, is proposed. The stationary and rotary parts of the proposed machine include both radially and axially laminated magnetic cores. Thanks to the special construction, the mechanical assembling of the proposed device in an integrated three-phase unit is very simple. In addition, a high permeance, low eddy current magnetic path is provided for the magnetic flux in the machine volume. However, to limit the core eddy currents in a normal range, a special geometry is selected for the radially laminated parts. Using the transformer magnetic equivalent circuit, the self and mutual inductances are obtained analytically. Based on the developed analytical model, geometrical dimensions are selected such that, a balanced three-phase machine is provided. Finally, finite-element analysis and experimental results are used to verify the obtained analytical model.
MSW recycling as a mechanism for the social inclusion in Brazil

This paper presents an evaluation of the recycling as a mechanism that can promote the social inclusion in Brazil. The analysis is based on the data from a Brazilian metropolitan, city of Campinas and is extended to Brazil. The results show that the municipality of Campinas collects monthly 8000 tons of recyclables, which if recycled can avail jobs to nearly 5000 waste collectors each receiving a minimum national salary of R$ 500/month, or alternatively can create 12,500 Family Grants at the value of R$ 200/month. In Brazil, the collected recyclables potential is about 1.2 million tons per month, which can avail jobs to 733,594 waste collectors or alternatively creates 1.8 million Family Grants. For these reasons, the authors propose the programme of selective collection and recycling as an alternative way to achieve the objective of the recommendation MDG1 of the UN.
Bayes factors for mixed-effects models

In psychology, we often want to know whether or not an effect exists. The traditional way of answering this question is to use frequentist statistics. However, a significance test against a null hypothesis of no effect cannot distinguish between two states of affairs: evidence of absence of an effect, and absence of evidence for or against an effect. Bayes factors can make this distinction; however, uptake of Bayes factors in psychology has so far been low for two reasons. Firstly, they require researchers to specify the range of effect sizes their theory predicts. Researchers are often unsure about how to do this, leading to the use of inappropriate default values which may give misleading results. Secondly, many implementations of Bayes factors have a substantial technical learning curve. We present a case study and simulations demonstrating a simple method for generating a range of plausible effect sizes based on the output from frequentist mixed-effects models. Bayes factors calculated using these estimates provide intuitively reasonable results across a range of real effect sizes. The approach provides a solution to the problem of how to come up with principled estimates of effect size, and produces comparable results to a state-of-the-art method without requiring researchers to learn novel statistical software.
SAGD Operating Strategies

The steam assisted gravity drainage (SAGD) process has emerged as an effective technology for the recovery of oil from oil sands deposits that are deeply buried for surface mining. In general, the process involves drilling paired horizontal wells, one well above the other and separated by a distance, near the bottom of the oil-bearing formation. The top well is used to inject steam into the oil sands, heating up the oil and allowing it to drain, under the action of gravity, into the bottom well. The paper first provides a review of the technological advances made in SAGD operating strategies. In addition to the successful field testing at the Underground Test Facility (UTF), the SAGD process has been recently extended to other types of reservoirs. These include reservoirs with lower permeability as compared to that at the UTF site and reservoirs with bottom water transition zones. Challenges facing application of the process in such types of reservoirs will be discussed. Concepts to overcome the challenges will be presented in terms of laboratory studies that have been carried out. The concepts tested include: the use of mechanical means such as drilling vertical drainage channels between paired horizontal wells; combining a vertical well with paired horizontal wells and potential for solvent and gaseous additives in steam (to improve SOR and reduce water requirements). Results provide valuable observations for field seale development of a more robust and economically viable process.
Group Medical Care: A Systematic Review of Health Service Performance

Group care models, in which patients with similar health conditions receive medical services in a shared appointment, have increasingly been adopted in a variety of health care settings. Applying the Triple Aim framework, we examined the potential of group medical care to optimize health system performance through improved patient experience, better health outcomes, and the reduced cost of health care. A systematic review of English language articles was conducted using the Cochrane Controlled Trials Register (CENTRAL), MEDLINE/PubMed, Scopus, and Embase. Studies based on data from randomized control trials (RCTs) conducted in the US and analyzed using an intent-to-treat approach to test the effect of group visits versus standard individual care on at least one Triple Aim domain were included. Thirty-one studies met the inclusion criteria. These studies focused on pregnancy (n = 9), diabetes (n = 15), and other chronic health conditions (n = 7). Compared with individual care, group visits have the potential to improve patient experience, health outcomes, and costs for a diversity of health conditions. Although findings varied between studies, no adverse effects were associated with group health care delivery in these randomized controlled trials. Group care models may contribute to quality improvements, better health outcomes, and lower costs for select health conditions.
Delineating the Relationships Between Motor, Cognitive-Executive and Psychiatric Symptoms in Female FMR1 Premutation Carriers

Introduction: Premutation expansions (55–200 CGG repeats) of the Fragile X Mental Retardation 1 (FMR1) gene on the X chromosome are associated with a range of clinical features. Apart from the most severe - Fragile X-Associated Tremor/Ataxia Syndrome (FXTAS) - where the most typical white matter changes affect cerebellar peduncles, more subtle changes may include impairment of executive functioning, affective disorders and/or subtle motor changes. Here we aimed to examine whether performance in selected components of executive functioning is associated with subclinical psychiatric symptoms in non-FXTAS, adult females carrying the FMR1 premutation. Methods and Sample: A total of 47 female premutation carriers (sub-symptomatic for FXTAS) of wide age range (26–77 years; M = 50.3; SD = 10.9) were assessed using standard neuropsychological tests, three motor rating scales and self-reported measures of psychiatric symptoms using the Symptom Checklist-90-Revised (SCL-90-R). Results: After adjusting for age and educational level where appropriate, both non-verbal reasoning and response inhibition as assessed on the Stroop task (i.e., the ability to resolve cognitive interference) were associated with a range of primary psychiatric symptom dimensions, and response inhibition uniquely predicted some primary symptoms and global psychiatric features. Importantly, lower scores (worse performance) in response inhibition were also strongly correlated with higher (worse) scores on standard motor rating scales for tremor-ataxia and for parkinsonism. Conclusion: These results provide evidence for the importance of response inhibition in the manifestation of psychiatric symptoms and subtle tremor-ataxia motor features, suggestive of the presence of early cerebellar changes in female premutation carriers.
Method for Detecting Step-Shaped Wear on Contact Strips by Measuring Catenary Vibration

The contact strip of a pantograph slides directly against the contact wire to collect current. The arcing between the contact wire and contact strip causes wear on the contact strip, leading to the development of step-shaped wear patterns. A contact strip with this step-shaped wear can catch and pull the contact wire, causing breakage. In this paper, a method is developed for detecting step-shaped wear on contact strips by using sensors arrayed on the wire to measure the vibration of the contact wire. Step-shaped wear produces characteristic vertical and lateral vibrations in the contact wire. An experimental test was used to evaluate the proposed method. Results showed that the contact wire moving from the top to the bottom of the step-shaped wear can be detected by using the kurtosis of acceleration, although this method occasionally misses wear for the pantograph passing at high speed. Using standard deviation of filtered lateral acceleration or the standard deviation of the lateral displacement of the hanger allows for the detection of the contact wire moving from the bottom to the top of step-shaped wear. No method produced false detection of step-shaped wear.
Privacy-Preserving Framework for Blockchain-based Stock Exchange Platform

This paper presents a privacy persevering framework for a decentralized stock exchange platform, ensuring anonymity and unlinkability of the investors’ accounts and their respective trading activities. The proposed framework meets these privacy requirements by (i) anonymizing both the unique account identifier (NIN) and balance information through customized data generalization and distortion techniques and (ii) making trading transactions unlinkable to their original investors by ensuring that both the NIN and balance are k-anonymous; i.e., k accounts belonging to different investors have the same balance. Moreover, to ensure long-term unlinkability, the process of anonymization is repeated at regular time intervals (every trading session). In addition to anonymity and unlinkability characteristics, the proposed framework is augmented with traceability and non-repudiation features. The simulation experiments with several market sizes and types confirm the effectiveness of the proposed framework in achieving full k-anonymity. Furthermore, to assess the overhead of the proposed privacy algorithms on the trading execution time, we conduct several experiments considering different anonymity levels k. We compare the transaction execution time of our proposed platform against a traditional non-privacy-preserving blockchain-based stock exchange. The obtained results for the worst-case scenarios show an acceptable execution time overhead.
Construction of sentimental knowledge graph of Chinese government policy comments

ABSTRACT Social Media Networks have developed into an important channel and platform for the collection and dissemination of policy information. Various policy comments on them have fully demonstrated the basic characteristics of big data. This paper introduces knowledge graphs into the sentiment analysis, analyses and sorts out the policy comments of China's mainstream social media platforms from 2016 to 2019, build a sentiment analysis dictionary, and then use the policy comments evaluation system to form sentiment knowledge graphs of policy comments that includes seven sentiments and five themes. The process of the sentiment knowledge graph constructed in this paper helps to more accurately understand the changes of online public opinion, and provides a theoretical basis for local governments to adjust the implementation of various policies. Apart from being the prototype of the automated sentiment knowledge graph system for policy comments, it can also be applied to other related hot topics.
FBAR Resonators with Sufficient High Q for RF Filter Implementation

Film Bulk Acoustic Wave Resonators (FBAR) at 2.6GHz using AlN piezoelectric material have been fabricated and characterized in this work. A stack of Al bottom electrode, AlN layer and top Al electrode is used to excite the thickness extensional (TE) vibration mode. The FBAR resonator has a quality factor of about 400 and the piezoelectric coupling coefficient of 4.25%, which is critical for RF filter implementation. Moreover, FBAR resonator has been designed to suppress spurious modes in order to ensure higher quality factor. Different filter topologies of ladder/lattice architecture are then explored for effective implementation using several FBAR resonators to build band-pass RF filters.
Influência da torra sobre a aceitação da bebida café

Sensory study of the roast type about acceptance of the coffee beverage The coffee is one of the few agricultural products that it is valued with base in qualitative parameters, in that as better the larger quality will be the obtained price. This quality, however, it is dependent of several factors that link in all the stages of the production of the coffee, from the choice of the variety or cultivars to be planted until the preparation of the beverage. The roasting is a very important stage for the quality of the coffee being directly related the acceptance of the beverage. The present work had for objective to evaluate the acceptance of the drink coffee of the type’s soft, hard and “rio” was submitted to three different types of roast (light, express and dark). An acceptance test was accomplished with 65 consumers of coffee using a hedonic scale of nine points, being evaluated the color, the aroma, the flavor and the global impression. The results obtained were analyzed by Internal Preference Map (PREFMD). The samples of roast dark independent of the class were of the consumers larger preference in relation to the attributes color, aroma, flavor and overall. The samples of roast light, “rio”/express and hard/express, in agreement with the consumers they had smaller preference? as the color. For the attributes aroma, flavor and overall the samples of roast light and “rio”/express were less accept.
Experiment of Power Supply Method for WLAN Sensor Using Both Energy Harvesting and Microwave Power Transmission

This paper proposes to improve effectiveness of supplying a sensor with energy using microwave power transmission (MPT) and energy harvesting (EH). The MPT duration should be as short as possible to avoid serious interference between the MPT and wireless local area network data transmission when co-channel operation of both microwave power transmission (MPT) and wireless data transmissions is performed. To shorten the MPT duration, we use multiple power sources such as an MPT source and an EH source to supply a sensor with power. Here, an overcharge or an energy shortage could occur at the sensor if the power supplied by both the MPT and EH sources is not adjusted appropriately. To solve this problem, the power supplied by multiple sources should be estimated precisely. In this paper, we propose a scheme for estimating the power supplied by multiple sources on the basis of an existing MPT scheduling system and then conducted an experiment using the scheme. From the experimental results, it is confirmed to estimate the power supplied by multiple sources successfully. In addition, the required MPT duration when the EH source is used is reduced compared to that when it is not used. Moreover, it is confirmed that the sensor station successfully estimates the power supplied by an MPT source and that by an EH source and adequately configures the MPT duration.
Distributed optimization with hybrid linear constraints for multi‐agent networks

This article investigates the distributed constrained optimization with hybrid linear constraints for multi‐agent networks, in which all the agents collaboratively minimize the global objective function with a sum of convex local objective functions, while the constraints are more general with local and global restrictions on the agents. Based on matrix and graph theories, a discrete‐time algorithm under distributed manner is designed to deal with the organized problems. In addition, the optimality of the presented algorithm is obtained under certain initial restriction for the agents. By virtue of a novel Lyapunov function and the optimal conditions, rigorous analysis shows the convergence of the multi‐agent networks with undirected and connected graphs. Finally, two simulation examples are presented to validate the theoretical consequence.
