Anxiety and Depression in Cardiac Inherited Disease: Prevalence and Association With Clinical and Psychosocial Factors
Authors: O'Donovan Claire E. , Skinner Jonathan R. , Broadbent Elizabeth
Published: December 2019

The small number of published studies indicate increased rates of anxiety and depression among patients with cardiac inherited diseases (CID). This study aimed to assess the prevalence of anxiety and depression in a New Zealand CID cohort and seek any associations with clinical and psychosocial factors.

Patients on a national CID register were sent a survey; 202 of 563 contactable patients participated (36% response rate). Ages ranged from 16 to 83 years (median 53). Most had Long QT Syndrome (43%) or Hypertrophic Cardiomyopathy (34%). Questionnaires collected demographic and psychological variables, including anxiety (GAD-7), depression (PHQ-9), illness perceptions, perceived risk and social support. The registry supplied clinical and genetic characteristics.

80 participants (42%) reported features of anxiety and/or depression. 24 (13%) reached clinical levels of depression, a greater proportion than that found in the general population. Poorer perceived social support was associated with worse anxiety (p < .001) and depression (p < .001) scores. Reporting more physical symptoms (p = .001) (commonly not caused by the CID) was associated with poorer depression scores and greater perceived consequences of the CID was associated with greater anxiety scores (p < .05). Neither anxiety nor depression were associated with time since diagnosis, disease severity or type of disease.

Forty percent of the CID population live with some degree of psychopathology but this did not correlate with disease severity, type of disease nor time since diagnosis. Correlating factors which may be modifiable include illness perceptions, various physical symptoms and social support.

Rates of clinical levels of anxiety and depression in this CID sample were 10% and 13% respectively.

Anxiety and depression were not associated with disease type, severity or time since diagnosis.

Perceived lack of support, consequences, and symptoms were associated with depression and anxiety.

High rates of anxiety and depression in CID’s indicate the need for access to psychological support.

Published: December 2019

The heterogeneity of national regulations in clinical psychology and psychological treatment across Europe requires a detailed description of every regulation to start a shared discussion. In the current paper, we describe the history, legal regulations, a specialized training program, the current status and some future challenges for clinical psychology in Spain. The evolution of clinical psychology in the Spanish National Health System (NHS) towards a health specialty regulated by law, exemplifies a balanced process of expansion, social recognition and professional settlement. Overall, the growth of clinical psychology in Spain may depend on access to leadership and management positions in the NHS that would allow a better organization of care resources to improve citizens’ access to psychological treatment.

Spanish regulation of clinical psychology is mediated by socio-cultural and political changes that occurred in the late 70's and 80’s in the country.

Recognition as a licensed clinical psychologist is obtained through a 4-year training system as an intern resident psychologist (PIR).

PIR is a training system of supervised internships, with increasing autonomy in various healthcare departments in the National Health System (NHS).

Achieving independent Clinical Psychology Services within the NHS in order to organize, implement and deliver evidence-based practices is currently one of our biggest challenges in the near future.

Published: December 2019

The study aims to analyze the process of internal conflict resolution between the Government of Indonesia and the separatist movement in Papua (Free Papua Movement (Indonesian: Organisasi Papua Merdeka or OPM)) using a horse-trading mechanism. This study was qualitative method by discussing the Free Papua Movement background and the conflict, then discussing the conflict process of timeline analysis tool to understand the development of its movement based on chronological order, and discussing the conflict resolutions that have been carried out with conflict mapping analysis tool to understand the actors that involved and their objectives. The conflict is the result of complexity among historical backgrounds, ideology, and a sense of injustice in Papua, on the other hand, the international community has increasingly supported Papua. Horse-trading has been used to resolve the conflict of Free Papua Movement and the Government of Indonesia, yet it has not yet reached a new resolution. The horse-trading mechanism effectively resolves the conflict when trust has been achieved between them to communicate both of them where they can deliver their objectives openly.
Fluid Thermal Effect on Non-contacting Labyrinth Seal of 20 MW Steam Turbine
Authors: Mammar Lahouari , Tayeb Yahiaoui , Ladjedel Omar , Šikula Ondřej
Published: December 2019

This paper is divided into two parts; the first describes a CFD analysis of a gland packing labyrinth seals in 20 MW steam turbine in LNG plant using ANSYS CFX code as an isothermal simulation in fluid domain. The results of two turbulence models k-ε and k-ω SST are compared and validated against experimental data. It is shown that the labyrinth seal leakage is proportional to the clearance cube so any variation in clearance can have a significant impact on the steam leakage. This clearance between the shaft and the labyrinth seal vary as a function of operating temperature due to the different rates of thermal expansion of the materials for these two components. Likewise the fluid temperature has a direct effect on fluid dynamic behavior. For that; the second part of the paper investigates the effect of fluid thermal conditions of the labyrinth seal via the heat transfer and Nusselt number variation in the stator and the rotor, for different cases of inlet temperature (400 °C, 200 °C, 100 °C, 50 °C) and pressure ratio (2.5, 4.5, 6.5) for an ideal gas. Also it is important to know the temperature distribution across tooth and cavities of the labyrinth seal, and finally the Influence of Inlet total temperature on fluid pressure drop in the labyrinth seal will be treated for improving and readjusting the steam turbine sealing system.

Published: December 2019

To understand variability and phenotypic association among body traits in West African Dwarf goats, morphological traits were examined based on location and sex. Two hundred and twenty-seven (227) goats in two Nigerian states were surveyed. Randomized complete block with Factorial treatment design, GLM, Pearson’s phenotypic correlation procedures of SAS® was employed. Morphological and index traits examined were body weight (BWT), hearth girth (HGH), diagonal trunk length (DTL), height at the withers (HWT), height at the rump (HRP); and Trunk length index (TLI), over-building index (OBI), body depth index (BDI), body breath index (BBI), withers-girth index (WGI), body-length index (BLI)and Weight-height index (WHI). BWT, DTL, TLI, OBI, BLI and WHI were influenced (P<0.05) by location, while DTL, TLI, OBI, BDI, BBI and BLI were influenced (P<0.05) by interaction of Location and Sex. Does recorded higher (P<0.05) BWT, TLI and BLI (27.75, 183.62 and 156.33), while Bucks had higher (P<0.05) DTL, HGH, HWT, HRP, OBI, BDI, BBI, WGI and WHI (80.57, 58.78, 46.89, 46.36, 99.29, 126.01, 127.01, -26.02 and 45.83). Ekiti goats recorded higher OBI, while Osun goats were higher on DTL, TLI, BLI and WHI (P<0.05). Highest correlation for females and males were between BWT/WHI (r =0.952/0.967, P<0.0001); for BWT/WHI were (r =0.969/0.972, 0.0001); and between HRP/HWT (r =0.953/0.929, P<0.0001) on Ekiti and Osun goats respectively. Between Ekiti and Osun goats BWT/WHI (r =0.969/0.972, P<0.0001) and HRP/HWT (r =0.953/0.929, P<0.0001) were obtained. CVs were highest on WGI (-69.65/-45.16); BWT (31.89/43.79), and WHI (29.25/35.54) for Does and Bucks; while WGI (-56.72/57.42), BWT (53.51/46.78) and WHI (42.09/36.76) were higher for Ekiti and Osun goats. Significant (P<0.0001) phenotypic correlation were obtained between BWT, DTL, HWT, HGH individually, and many other traits (r =0.336-0.957).

LEGISLAÇÃO NO COMBATE AO EXTREMISMO RELIGIOSO: O EXEMPLO DO AZERBAIJÃO
Authors: De Nadal Luz Emanuelle Luana , Klaus Júnior Cláudio Antônio
Published: December 2019

A religião é um fenômeno social que emergiu tanto como sistema de crenças quanto como forma de gestão da sociedade por muitos séculos. Dado que mais de dois terços da população mundial são crentes de diferentes religiões, as relações entre religião e estado, bem como religião e sociedade, sempre manterão sua atualidade. Para manter a paz, a tolerância e o multiculturalismo no mundo atual, existe uma grande necessidade de distinguir a liberdade de fé do radicalismo religioso, do extremismo religioso e do fanatismo. O direito como regulador das relações sociais, visa assegurar a sobrevivência, os direitos individuais, às liberdades individuais e tornar-se previsível e legítimo. A legislação e os estatutos nascem do direito para que, de forma pública e registrada, as pessoas possam conhecer as regras da sociedade em que vivem. Utilizando-se de conceitos de direito e legislação este trabalho visa expor o exemplo do Azerbaijão em seu direito nacional agindo como protetor das liberdades individuais. O Azerbaijão é localizado na região da Transcaucásia da Eurásia, entre a Ásia Ocidental e a Europa Oriental, marcado pelo multiculturalismo, é uma referência na legislação em combate ao extremismo religioso. Um panorama histórico do país é apresentado para a compreensão da evolução histórica que culmina na atual cultura da tolerância e aceitação do multiculturalismo.

Touchstones for Sustainable Development: Indigenous Peoples and the Anthropology of Sustainability in Our Common Future
Authors: Ødemark John
Published: December 2019

The Anthropocene is regularly invoked as an occasion for the rethinking of the Anthropos, for instance through a reexamination of human origin stories. This article examines one such anthropological origin story; the construction of an exemplary and sustainable humanity based upon notions of “indigenous cultures” in Our Common Future in the context of D. Chakrabarty’s call for a history of the human that merges the biological and cultural archives of humanity. The UN report, Our Common Future, first formulated “sustainable development” as a global policy. Through a close reading of the report, the article demonstrates that a combined ecological and anthropological exemplarity is associated with “indigenous and tribal peoples”, who are also construed as living examples of sustainable living for the global society, and links to humanity’s past. Furthermore, the article aims to show that particular conceptions of “culture” and “ecological” wholes enables a translation between different scales, between local and “bounded” indigenous cultures and earth as the bounded habitat of humanity. The fusion of the concepts of “development” and “sustainability” in Our Common Future lies behind present UN concerns with sustainable development goals in current international policy. Hence, an inquiry into the anthropological and cultural historical assumptions of the report is vital. Questions of natural and cultural time have come to dominate discussions of the Anthropocene. The article also reconnects the global scale with a very literal struggle over space inside the Brazilian nation state, through reading the comment on the report from Ailton Krenak. Applying what we could call a language of survival, Krenak relates the global eco-political scale of OCF with a very concrete struggle over territory inside the political space of the Brazilian nation state.

Published: December 2019

Ultrasound-assisted extraction (UAE) was applied as a pretreatment technique to improve the recovery of polyphenols from the almond hulls of four Tunisian and three Italian almond varieties, followed by the characterization with HPLC-DAD. The operating parameters (solid/liquid ratio, extraction time, and ethanol concentrations) were optimized using a Response Surface Methodology. A polynomial equation was calculated to describe the relationship between the operating parameters and dependent variables as total polyphenolic content (TPC) and antioxidant activity (RSA). A desirability function approach was used to determine the optimum conditions for operating parameters: a solid:solvent ratio of 2 g/100 mL, an extraction time of 13 min, and an ethanol concentration of 51.2%. Among the almond varieties, Pizzuta and Fakhfekh showed the highest polyphenol content and antioxidant activity. HPLC-DAD analysis of almond hull extracts confirmed that chlorogenic acid, catechin, and protocatechuic acid were the most important polyphenols in almond hull. The results highlighted that UAE could be an effective technique for the recovery of phenolic compounds from almond hull, thereby making this byproduct a promising source of compounds with potential applications in food and healthcare sectors.
Extending Appearance Based Gait Recognition with Depth Data
Authors: Lenac Kristijan , Sušanj Diego , Ramakić Adnan , Pinčić Domagoj
Published: December 2019

Each individual describes unique patterns during their gait cycles. This information can be extracted from the live video stream and used for subject identification. In appearance based recognition methods, this is done by tracking silhouettes of persons across gait cycles. In recent years, there has been a profusion of sensors that in addition to RGB video images also provide depth data in real-time. When such sensors are used for gait recognition, existing RGB appearance based methods can be extended to get a substantial gain in recognition accuracy. In this paper, this is accomplished using information fusion techniques that combine features from extracted silhouettes, used in traditional appearance based methods, and the height feature that can now be estimated using depth data. The latter is estimated during the silhouette extraction step with minimal additional computational cost. Two approaches are proposed that can be implemented easily as an extension to existing appearance based methods. An extensive experimental evaluation was performed to provide insights into how much the recognition accuracy can be improved. The results are presented and discussed considering different types of subjects and populations of different height distributions.
Equivalent Frame Model with a Decaying Nonlinear Moment-Curvature of Steel-Reinforced Concrete Joints
Authors: Montava Isaac , Irles Ramón , Estevan Luis , Vives Ismael
Published: December 2019

A numerical model for the analysis of frame structures that is capable of reproducing the behavior of reinforced concrete (RC) members and steel-reinforced concrete (SRC) members in all steps until collapse by simulating a reduced resistance capacity is presented in this work. Taking into account the solid models obtained in previous research that have been validated by experimental results, moment-curvature graphics were obtained in all steps: elastic, plastic, and post-critical to collapse. Beam models versus 3D models considerably simplified the calculation of frame structures and correctly described both the plastic and post-critical phases. The moment-curvature graph can be used in a simplified frame analysis, from post critical behavior to collapse.
Analysis of Application Parameters of Hydraulic Slotting Technology in Jointed Coal Reservoirs
Authors: Ge Zhaolong , Zuo Shaojie , Wang Yingwei , Lyu Youchang , Feng Xinyan
Published: December 2019

Hydraulic slotting technology is typically used in coal mines to enhance permeability and prevent gas outbursts. Because a coal seam contains many cleats and joints, this study investigated the influence of conventional application parameters on the hydraulic slotting effect by numerical simulation and experimental testing. The cleats in the coal generated stress concentration and initiated with the water jet impact, which promoted the formation of a complex fracture network. The optimized arrangement included angles with an inclination of 20–45° between the borehole and the coal seam strike. The water jet pressure and rotation speed determined the shape of the slot. A high water jet pressure and low rotation speed promoted the formation of cracks at the end of the slot and strengthened the permeability-enhancing effect. Coal fragments could more easily peel off from the sides of the seam and block the borehole. The high water pressure and low rotation speed application parameters were optimized without blocking the borehole. Results obtained by field application revealed that the gas extraction flow after optimization was 1.3 times that of conventional hydraulic slotting. An appropriate angle between the cleats and borehole can more effectively increase the permeability of the coal seam and results in higher gas drainage flow. The results of this study can be useful as guidelines for field applications of hydraulic slotting technology.
Adaptive-Uniform-Experimental-Design-Based Fractional-Order Particle Swarm Optimizer with Non-Linear Time-Varying Evolution
Authors: Yang Po-Yuan , Chou Fu-I , Tsai Jinn-Tsong , Chou Jyh-Horng
Published: December 2019

An adaptive-uniform-experimental-design-based fractional particle swarm optimizer (AUFPSO) with non-linear time-varying evolution (NTE) is proposed. A particle swarm optimizer (PSO) is an excellent evolutionary algorithm due to its simple structure and rapid convergence. Nevertheless, PSO has notable drawbacks. Although many proposed methods and strategies have enhanced its effectiveness and performance, PSO is limited by its tendency to fall into local optima and its tendency to obtain different solutions in each search (i.e., its weak robustness). Introducing fractional-order calculus in PSO (FPSO) can correct the order of the velocity derivative for each particle, which enhances the diversity and algorithmic effectiveness. This study used NTE of the order of the velocity derivative, inertia weight, cognitive parameter, and social parameter in an FPSO used to search for a global optimal solution. To obtain the best combination of FPSO and NTE, an adaptive uniform experimental design (AUED) method was used to deal with this essential issue. The AUED method integrates a uniform layout with the best combination phase and a stepwise ratio to assist in selecting the best combination for FPSO-NTE. Experimental applications in 15 global numerical optimization problems confirmed that the AUFPSO-NTE had a better performance and robustness than existing PSO-related algorithms.
Blockchain-Based Resource Allocation Model in Fog Computing

Published: December 2019

Fog computing makes up for the shortcomings of cloud computing. It brings many advantages, but various peculiarities must be perceived, such as security, resource management, storage, and other features at the same time. This paper investigates the resource contribution model between the fog node and cloud or users when fog computing introduces blockchain. The proposed model practices the reward and punishment mechanism of the blockchain to boost the fog nodes to contribute resources actively. The behavior of the fog node in contributing resources and the completion degree of the task also for contributing resources are packaged into blocks and stored in the blockchain system to form a transparent, open, and tamper-free service evaluation index. The differential game method is employed to model and solve the above process and address the interaction between the optimal resource contribution strategy of the fog node and the optimal benefit under the optimal resource contribution strategy. Indirectly, this service evaluation index also brings long-term economic benefits to fog service providers. Besides, taking advantage of the performance characteristics of the collective maintenance of blockchain and the ability to establish a credible consensus mechanism in an untrusted environment, fog computing nodes, under the proposed architecture, can have specific security protection capabilities.
Preparation of Co-Ni Alloy Coating with Stable Composition by Jet-Electrodeposition
Authors: Zhang Qing , Tan Jun , Meng Lingdong , Xie Fengkuan , Zhao Haichao , Yan Zang
Published: December 2019

Cobalt-Nickel (Co-Ni) alloy coatings were prepared by jet electrodeposition on brass substrate under different Co2+/Ni2+ ratio contents (M = 2:1, 1:1, 1:2 and 1:3) and solution flow rates (from 2.0 to 4.5 L/min). The surface morphology, element content, and phase structure of the coating were observed by scanning electron microscope (SEM), energy dispersive spectrometer (EDS), and X-ray diffractometer (XRD). The hardness and wear resistance of the coatings were also measured. The results showed that the Co content in coatings was greater than 70%, no matter at what flow rate and concentration. With an increase of the flow rate, the Co content in the coating increases, and the grain size on the surface of the coating decreases, which leads to increased hardness of the coating. However, the flow rate of the plating solution has little effect on the grain growth orientation, and the phase structure is dominated by the elemental content of the coating. The coatings are in a single phase of hexagonal close-packed (HCP) when the Co content is more than 80%, while the coatings are in dual phases of the HCP and face-centered cubic (FCC) when the Co content is less than 80%. With an increase in the Co content, the grain size decreases, and consequently, the hardness and wear resistance of the alloy increase. A Co-Ni alloy coating with stable composition can be obtained when the ratio of Co2+ to Ni2+ is 2:1.
Simulation Study of Two Torque Optimization Methods for Direct Torque-Controlled Induction Motors
Authors: Albalawi Hani , Zaid Sherif A. , Buswig Yonis M.
Published: December 2019

The simplicity and excellent dynamic performance of Direct Torque Control (DTC) make Induction Motor (IM) drives attractive for many applications that require precise torque control. The traditional version of DTC uses hysteresis controllers. Unfortunately, the nature of these controllers prevents the optimization of the inverter voltage vectors inside the flux hysteresis band. The inverter voltage vector optimization can produce fast torque response of the IM drive. This research proposes two torque optimization methods for IM systems utilizing DTC. Analysis and Matlab simulations for the proposed optimization methods prove that the torque and, consequently, the speed responses, are greatly improved. The performances of the drive system controlled by the proposed optimization methods and the traditional DTC are compared. Conversely, the effects of the parameters on the proposed optimization methods are introduced. The proposed methods greatly improve the torque and speed dynamic performances against the traditional DTC technique. However, one of the proposed optimization methods is more sensitive to IM parameter variations than the other.

The pecan (Carya illinoinensis) nut shell is an important byproduct of the food processing industry that has not been previously explored as an antioxidant compound. This work aims to study the effect of the extrusion temperature and screw speed on the moisture content, water and oil absorption index, water solubility index, color, phenolic compounds, condensed tannin compounds, and antioxidant activity of pecan nut shell extrudates. Extrusion variables were adjusted using a response surface methodology. Extrusion, performed at 70 °C and 150 rpm, almost doubled the concentration of polyphenols in the non-extruded shell and significantly increased radical scavenging activity. Compounds in extrudates, performed at 70 °C and 150 rpm, were quantified by high-performance liquid chromatography (HPLC) with a diode-array detector (DAD) and identified by liquid chromatography coupled with time-of-flight mass spectrometry (LC-MSD-TOF). Extrusion significantly increased most phenolic acid compounds, including gallic acid, ellagic acid pentose, ellagic acid, dimethyl ellagic acid rhamnoside, and dimethyl ellagic acid. The soluble fiber in extrudates was more than three-fold higher than in the control. Therefore, extrusion at 70 °C and 150 rpm increased the concentration of phenolic compounds, antioxidant activity, and total dietary and soluble fiber. Our findings support the notion that extruded pecan nut shell can be used in clean-label products and improve their nutraceutical value.

Studies examining the experience of children returned from foster care can reveal its causes and the severity of the psychological consequences, as well as the positive effect of psychological support on family functioning. Our research was aimed at the features of children and characteristics of foster families who refuse to continue parenting foster children. The study participants were comprised of families raising a foster child (Group One—182 families), and families who refused to continue parenting and returned the child (Group Two—19 families). The study was conducted using the “standardized interview for parents” and the “list of traumatic experiences of the child.” The results show that the strongest contributor to foster family breakdown was the degree of the child’s traumatic experience before placement (for Group One, 3.9 (1.15); Group Two, 6.1 (1.31), U = 395.0, p < 0.001) and the minimal participation of the family in an intervention program (the total number of program activities the family did not participate in; for Group One, 48.5 (28.27)%, Group Two, 95.5 (2.58)%, U = 67.5, p < 0.001). Our data expand ideas about the functioning of foster families who have taken children with significant traumatic experience and indicate the need to improve the quality of psychological and social support to foster families as an important factor in preventing secondary returns.

Published: December 2019

The application of electric field promotes benzene oxidation significantly over Pd/CoxCey catalysts. For 1% Pd loading catalysts, the complete oxidation of benzene can be realized at 175 °C with an electric field under an input current of 3 mA, 79 °C lower than the temperature demanded for complete benzene conversion without electric field. The introduction of electric field can save Pd loading in the catalysts while maintaining high benzene conversion. The characterization experiments showed that CeO2 reduction was accelerated with electric field and created more active oxygen, promoting the formation of active sites on the catalyst surface. The OH removal ability of PdO was enhanced by forming CoO(OH) species, which can easily dehydroxylate since the reduction of Co3+ was promoted by the electric field. The optimized Ce/Co ratio is a balance between oxygen availability and OH removal ability.
Thermal and Quantum Fluctuation Effects in Quasiperiodic Systems in External Potentials
Authors: Cinti Fabio , Macrì Tommaso
Published: December 2019

We analyze the many-body phases of an ensemble of particles interacting via a Lifshitz–Petrich–Gaussian pair potential in a harmonic confinement. We focus on specific parameter regimes where we expect decagonal quasiperiodic cluster arrangements. Performing classical Monte Carlo as well as path integral quantum Monte Carlo methods, we numerically simulate systems of a few thousand particles including thermal and quantum fluctuations. Our findings indicate that the competition between the intrinsic length scale of the harmonic oscillator and the wavelengths associated to the minima of the pair potential generically lead to a destruction of the quasicrystalline pattern. Extensions of this work are also discussed.

Published: December 2019

To improve the physicochemical properties of valnemulin (VLM), different solid forms formed by VLM and organic acids, including tartaric acid (TAR), fumaric acid (FUM), and oxalic acid (OXA), were successfully prepared and characterized by using differential scanning calorimetry (DSC), scanning electron microscope (SEM), X-ray powder diffraction (XRPD), and Fourier-transform infrared spectroscopy (FT-IR). The excess enthalpy Hex between VLM and other organic acids was calculated by COSMOthermX software and was used to evaluate the probability of forming multi-component solids between VLM and organic acids. By thermal analysis, it was confirmed that multi-component solid forms of VLM were thermodynamically more stable than VLM itself. Through dynamic vapor sorption (DVS) experiments, it was found that three multi-component solid forms of VLM had lower hygroscopicity than VLM itself. Furthermore, the intrinsic dissolution rate of VLM and its multi-component forms was determined in one kind of acidic aqueous medium by using UV-vis spectrometry. It was found that the three multi-component solid forms of VLM dissolved faster than VLM itself.

Published: December 2019

Deep Learning (DL) and Artificial Intelligence (AI) tools have shown great success in different areas of medical diagnostics. In this paper, we show another success in orthodontics. In orthodontics, the right treatment timing of many actions and operations is crucial because many environmental and genetic conditions may modify jaw growth. The stage of growth is related to the Cervical Vertebra Maturation (CVM) degree. Thus, determining the CVM to determine the suitable timing of the treatment is important. In orthodontics, lateral X-ray radiography is used to determine it. Many classical methods need knowledge and time to look and identify some features. Nowadays, ML and AI tools are used for many medical and biological diagnostic imaging. This paper reports on the development of a Deep Learning (DL) Convolutional Neural Network (CNN) method to determine (directly from images) the degree of maturation of CVM classified in six degrees. The results show the performances of the proposed method in different contexts with different number of images for training, evaluation and testing and different pre-processing of these images. The proposed model and method are validated by cross validation. The implemented software is almost ready for use by orthodontists.

This study investigated the application of a modified percussion entropy index (PEIPPI) in assessing the complexity of baroreflex sensitivity (BRS) for diabetic peripheral neuropathy prognosis. The index was acquired by comparing the obedience of the fluctuation tendency in the change between the amplitudes of continuous digital volume pulse (DVP) and variations in the peak-to-peak interval (PPI) from a decomposed intrinsic mode function (i.e., IMF6) through ensemble empirical mode decomposition (EEMD). In total, 100 middle-aged subjects were split into 3 groups: healthy subjects (group 1, 48–89 years, n = 34), subjects with type 2 diabetes without peripheral neuropathy within 5 years (group 2, 42–86 years, n = 42, HbA1c ≥ 6.5%), and type 2 diabetic patients with peripheral neuropathy within 5 years (group 3, 37–75 years, n = 24). The results were also found to be very successful at discriminating between PEIPPI values among the three groups (p < 0.017), and indicated significant associations with the anthropometric (i.e., body weight and waist circumference) and serum biochemical (i.e., triglycerides, glycated hemoglobin, and fasting blood glucose) parameters in all subjects (p < 0.05). The present study, which utilized the DVP signals of aged, overweight subjects and diabetic patients, successfully determined the PPI intervals from IMF6 through EEMD. The PEIPPI can provide a prognosis of peripheral neuropathy from diabetic patients within 5 years after photoplethysmography (PPG) measurement.
Jointly Modeling Autoregressive Conditional Mean and Variance of Non-Negative Valued Time Series
Authors: Kawakatsu Hiroyuki
Published: December 2019

This paper considers observation driven models with conditional mean and variance dynamics for non-negative valued time series. The motivation is to relax the restriction imposed on the higher order moment dynamics in standard multiplicative error models driven only by the conditional mean dynamics. The empirical fit of a zero inflated mixture distribution is assessed with trade duration data with a large fraction of zero observations. All authors have read and agreed to the published version of the manuscript.
Relationship Satisfaction and Infidelity-Related Behaviors on Social Networks: A Preliminary Online Study of Hispanic Women
Authors: González-Rivera Juan Aníbal , Aquino-Serrano Francisco , Pérez-Torres Emily M.
Published: December 2019

The purpose of this online study was to develop an explicative model regarding the origin of infidelity-related behaviors on social networks for Hispanic women. We propose that sexual satisfaction and emotional intimacy have a direct impact on the satisfaction of couple relationships, and an indirect impact in the development of infidelity-related behaviors on social networks. To investigate this proposal, we used a non-probabilistic sample of 341 Hispanic women living in Puerto Rico. Statistical analyses confirmed that satisfaction and ambivalence in couple relationship completely mediate the association between sexual satisfaction and infidelity-related behaviors on social networks, as well as the relationship between emotional intimacy and infidelity-related behaviors on social networks. Overall, women who practice infidelity-related behaviors on social networks showed less sexual satisfaction, less emotional intimacy, less relationship satisfaction, and greater ambivalence. Our results provide theoretical and empirical evidence on how infidelity-related behaviors on social networks develop in couple relationships, and these results could help to inform possible forms of prevention and intervention.

Published: December 2019

This article aims to analyze the influence of professional training on the digital competence of tourism students at a Mexican public university. For this, a quantitative methodology was used through the application of a survey amongst 400 students. Moreover, the partial least squares structural equation modeling (PLS-SEM) and other multivariate techniques were used to test the hypotheses. The results show that the role of teaching, the curriculum proposal, and the student autonomy as part of professional training all have an impact on digital competence in order to generate and effectively use digital knowledge, manage information in support of their activities and use the media in individual and collective channels, as well as emancipate collaborative learning and maintain leadership in the network. It is discussed how the emphasis of curricular programs and the support of teachers play a significant role as cultivators of digital competence, as well as the initiative and independence of students to better exploit digital media for their personal, academic and professional activities.

The proposed design covers an area of 29.5 × 61.4 mm2, wherein each antenna covers an area of 11.82 × 25.28 mm2. The dimensions of the microstrip lines in each MIMO element were optimized to achieve a good impedance matching. The design is resonating at 61 GHz, with a wide practical bandwidth of more than 7 GHz, thereby covering IEEE 802.11ad WiGig (58–65 GHz). The average value of gain ranges from 9.45 to 13.6 dBi over the entire frequency bandwidth whereas, the average value of efficiency ranges from 55.5% to 84.3%. The proposed design attains a compact volume, wide bandwidth, and good gain and efficiency performances, which makes it suitable for WiGig terminals.
