Effective Estimation of Hourly Global Solar Radiation Using Machine Learning Algorithms

The precise estimation of solar radiation is of great importance in solar energy applications with respect to installation and capacity. In estimate modelling on selected target locations, various computer-based and experimental methods and techniques are employed. In the present study, the Multilayer Feed-Forward Neural Network (MFFNN), K -Nearest Neighbors ( K -NN), a Library for Support Vector Machines (LibSVM), and M5 rules algorithms, which are among the Machine Learning (ML) algorithms, were used to estimate the hourly average solar radiation of two geographic locations on the same latitude. The input variables that had the most impact on solar radiation were identified and grouped as a result of 29 different applications that were developed by using 6 different feature selection methods with Waikato Environment for Knowledge Analysis (WEKA) software. Estimation models were developed by using the selected data groups and all input variables for each target location. The results show that the estimations developed with the feature selection method were more successful for target locations, and the radiation potentials were similar. The performance of the estimation models was evaluated by comparing each model with different statistical indicators and with previous studies. According to the RMSE, MAE, R 2 , and SMAPE statistical scales, the results of the most successful estimation models that were developed with MFFNN were 0.0508-0.0536, 0.0341-0.0352, 0.9488-0.9656, and 7.77%-7.79%, respectively.
Sports Chaplaincy, Theology and Social Theory Disrupting Performance-Based Identity in Elite Sporting Contexts

Existing literature on the work of sports chaplains has focused primarily on practitioner accounts of chaplaincy with elite athletes. While these narratives provide useful descriptions of personal experience and practical application, they are largely devoid of theoretical grounding. This paper seeks to address this imbalance by proposing the need for sports chaplains to have a more critical understanding of sport and its relational dynamics. We begin by problematizing some of the historical assumptions underpinning elite sport, especially in relation to identity formation. We then explore some of the moral dilemmas which may be experienced by Christian athletes who inhabit contemporary sporting contexts. In line with the work of established sociological scholars, we then move to a critical analysis of performance-based identity and how an understanding of sociological concepts and ideas might assist chaplains in their work with elite athletes. The paper concludes by identifying sports chaplains as key figures in the disruption of performance-based identity.
An Examination of Translingual Practices on a Mobile Application

This article reports Korean speakers’ experiences with naturally occurring translingual transliterations in a noneducational online contact zone to support improvement of English pronunciation. Use of the Korean and English alphabets in pronunciation transliterations and application users’ meaning-making are analyzed using Canagarajah’s (2013) macrotranslingual strategies for negotiation. Findings show that the nonstandard transliterations could easily deliver pronunciations to a broad audience and stimulate the participation of users, who draw on diverse resources to strategically negotiate their footings to make meaning, often referring to their linguistic knowledge or experiences in certain countries. Patterns around transliteration and negotiation suggest two major implications for classroom pronunciation instruction: using students’ existing resources to address crucial features of intelligibility such as vowel quality and suprasegmental features in transliterations, in addition to segmentals, and eliciting students’ active involvement in meaning construction. Furthermore, English teachers might challenge their students’ acceptance of prevalent monolingual standards in pronunciation and establish their translingual sensitivity to cultural/linguistic diversity.
Growth Uniformity in Selective Area Epitaxy of AlGaN/GaN Heterostructures for the Application in Semiconductor Devices

The design of modern semiconductor devices often requires the fabrication of three-dimensional (3D) structures to integrate microelectronic components with photonic, micromechanical, or sensor systems within one semiconductor substrate. It is a technologically challenging task, as a strictly defined profile of the device structure is obligatory. This can be achieved either by chemical etching or selective deposition on a masked substrate. In this paper, the growth uniformity of AlGaN/GaN heterostructures during selective-area metalorganic vapour-phase epitaxy (SA-MOVPE) was studied. Such structures are typically used in order to fabricate high-electron-mobility transistors (HEMT). The semiconductor material was deposited through 200 μm long stripe-shaped open windows in a SiO2 mask on GaN/sapphire templates. The window width was varied from 5 μm to 160 μm, whereas mask width separating particular windows varied from 5 μm to 40 μm. The experiment was repeated for three samples differing in GaN layer thickness: 150 nm, 250 nm, and 500 nm. Based on theoretical models of the selective growth, a sufficiently uniform thickness of epitaxially grown AlGaN/GaN heterostructure has been achieved by selecting the window half-width that is smaller than the diffusion length of the precursor molecules. A Ga diffusion length of 15 μm was experimentally extracted by measuring the epitaxial material agglomeration in windows in the dielectric mask. Measurements were conducted while using optical profilometry.
Osteopathic Manipulative Treatment in Tension Headaches

Tension-type headaches, associated with young age, poor health, sleep disturbances, anxiety, stress, and poor posture, account for 90% of all headaches diagnosed by healthcare professionals. Diagnosis and treatment of the various headache subtypes are often aimed at determining the underlying cause but commonly involve over-the-counter pain medication. Because recurrence is common in tension-type headaches, with a subsequent refractory response to over-the-counter medications, adjunctive and alternative treatment modalities should be further studied. Here we present a case of tension headache initially non-responsive to pain medication but resolved with osteopathic manipulative treatment and lifestyle modifications. Osteopathic considerations and literature are also reviewed in the broader context of headache management.
Zinc tin oxide thin-film transistors via reactive sputtering using a metal target

Zinc tin oxide based thin-film transistors are fabricated via reactive magnetron sputtering using a metallic zinc/tin alloy target. The oxygen partial pressure and total sputtering pressure are explored. An oxygen partial pressure and total sputtering pressure of 0.8 and 30mTorr, respectively, are found to be optimal. Devices with a reactively sputtered zinc tin oxide channel layer and channel layer annealing of 500°C exhibit incremental mobilities of ∼32cm2V−1s−1, turn-on voltage of ∼−4V and drain current on-to-off ratios of ∼107. Both direct current and radio frequency magnetron sputtering are explored showing similar characteristics.
Structure, optical and magnetic properties of Ni@Au and Au@Ni nanoparticles synthesized via non-aqueous approaches

Although the combination of magnetic and noble metals in core-shell nanoparticles is very useful in many applications, the preparation of magnetic-noble bimetallic core-shell nanoparticles with uniform shells remains a great challenge due to large mismatch of crystal lattices between magnetic and noble metals. Herein we present non-aqueous methods for combing Au and Ni in nanoscale to form a core-shell structure. Ni@Au nanoparticles were prepared via an injection-quenching process in which Au precursors decomposed and formed closed shells on pre-formed Ni seeds synthesized in oleylamine, whereas Au@Ni nanoparticles were obtained in a one-step reaction involving a seed-catalyzed mechanism. The formed core-shell structure was confirmed by high-angle annular dark-field imaging along with the analyses of energy-dispersive X-ray spectroscopy and high-resolution transmission electron microscopy. UV-Visible absorption spectroscopy and superconducting quantum interference device magnetometer were used to characterize the optical and magnetic properties of the as-prepared bimetallic core-shell nanoparticles. Through the adjustment of growth conditions, Ni@Au and Au@Ni nanoparticles with different core or shell dimensions and morphologies were obtained, which offers an important means to tailor their optical and magnetic properties for multiple practical applications.
Project-Based Learning Environment: Integration of an Educational Robot Arm with Computer Vision and ROS

Robotics is a science, which aims at controlling mechanical systems through electrical systems and computer techniques. Robotics has a high rate of applicability but, in order to make it easier to comprehend when it comes to learning processes, methodologies that enhance the student's performance and learning curve, like the project-based learning method, are indispensable. The project-based learning technique diverges from the conventional approach, as it makes the many students the object itself of their learning development, by giving them the power of choice and major control over the entire process. This article aims at presenting the project developed by students from the “Robotics and Its Elements” class ministered at Universidade Federal de Ouro Preto - UFOP. The project dealt with concepts, approaches, explanations, and techniques that created a robot-cell (Melfa RV-2AJ and its peripherals) which used the ROS framework system alongside computer vision resources. The robot, after its completion, was able to perform repetitive tasks such as the detection and gathering of specific physical elements – it can manipulate them properly. To make those tasks possible, a Kinect camera was used to obtain data such as the depth and location of the elements which were in the robot's range of grasp. In addition, a detection mechanism derived from the combination of an open source graphic library called OpenCV with the usage of the HSV color system was an important accessory, so that color calibration and orientation addressed properly. Finally, the designated framework (ROS) suited to establish a connection between the robot and its whole operational environment, in order to make the data-sharing and input signal both able to work over the robot's mobility.
Recombinant Technologies to Improve Ruminant Production Systems: The Past, Present and Future

The use of recombinant technologies has been proposed as an alternative to improve livestock production systems for more than 25 years. However, its effects on animal health and performance have not been described. Thus, understanding the use of recombinant technology could help to improve public acceptance. The objective of this review is to describe the effects of recombinant technologies and proteins on the performance, health status, and rumen fermentation of meat and milk ruminants. The heterologous expression and purification of proteins mainly include eukaryotic and prokaryotic systems like Escherichia coli and Pichia pastoris. Recombinant hormones have been commercially available since 1992, their effects remarkably improving both the reproductive and productive performance of animals. More recently the use of recombinant antigens and immune cells have proven to be effective in increasing meat and milk production in ruminant production systems. Likewise, the use of recombinant vaccines could help to reduce drug resistance developed by parasites and improve animal health. Recombinant enzymes and probiotics could help to enhance rumen fermentation and animal efficiency. Likewise, the use of recombinant technologies has been extended to the food industry as a strategy to enhance the organoleptic properties of animal-food sources, reduce food waste and mitigate the environmental impact. Despite these promising results, many of these recombinant technologies are still highly experimental. Thus, the feasibility of these technologies should be carefully addressed before implementation. Alternatively, the use of transgenic animals and the development of genome editing technology has expanded the frontiers in science and research. However, their use and implementation depend on complex policies and regulations that are still under development.
Information Complexity Criterion for Model Selection in Robust Regression Using A New Robust Penalty Term.

Model selection is basically a process of finding the best model from the subset of models in which the explanatory variables are effective on the response variable. The log likelihood function for the lack of fit term and a specified penalty term are used as two parts in a model selection criteria. In this paper, we derive a new tool for the model selection in robust regression. We introduce a new definition of relative entropy based on objective functions. Due to the analytical simplicity, we use Huber's objective function $\rho_H$ and propose our specified penalty term $C_0^{\rho_H}$ to derive new Information Complexity Criterion ($RICOMP_{C_0^{\rho_H}}$) as a robust model selection tool. Additionally, by using the properties of $C_0^{\rho_H}$, we propose a new value of tuning parameter called $k_{C_0}$ for the Huber's $\rho_H$. If a contamination to normal distribution exists, $RICOMP_{C_0^{\rho_H}}$ chooses the true model better than the rival ones. Monte Carlo Simulation studies are carried out to show the utility both of $k_{C_0}$ and $RICOMP_{C_0^{\rho_H}}$. A real data example is also given.

Este estudio tuvo como objetivo evaluar el nivel de asimetría entre las preocupaciones de los auditores y los factores de riesgo de las instituciones financieras registradas en B3 (Brasil, Bolsa, Balcão – la bolsa de valores de Brasil). Esta investigación se caracteriza por ser exploratoria, documental, cualitativa y cuantitativa. Los procedimientos metodológicos adoptados pueden considerarse en cuatro fases: (i) recopilación de formularios de referencia y estados financieros estandarizados, fecha base 2016, de 25 instituciones financieras; (ii) categorización, por parte de los autores, de los riesgos identificados e informados por las empresas en el formulario de referencia; (iii) categorización, por parte de los autores, de los principales asuntos de auditoría; y (iv) análisis de los hallazgos. En general, hubo un bajo nivel de asimetría entre los factores de riesgo de las entidades y los principales problemas desde el punto de vista de los auditores. Esta baja asimetría de los riesgos de las entidades y los principales problemas desde el punto de vista de los auditores pueden representar una falta de transparencia en el conocimiento de los riesgos por parte de los inversores.
Development and characterization of highly structured rinse-off conditioners containing vegetable oils

Abstract The appearance of the hair interferes with people's self-esteem and may indicate characteristics about their lifestyle. Due to their importance, hair treatment cosmetics correspond to a significant portion of the sector's sales. This research aimed to develop and characterize highly structured conditioners, prepared with avocado, wheat germ and grape seeds oils. The formulations were developed through a ternary phase diagram, using cationic surfactant (cetyl trimethyl ammonium chloride), oily phase (mineral or vegetable oils) and aqueous phase. The formulations obtained were classified according to their aspect and viscosity, with the most appropriate ones chosen for the intended use. They were evaluated by polarized light microscopy (PLM) to verify the structure of the system and, also, by means of rheology, small angle X-ray scattering (SAXS) and sun protection factor (SPF) determination. After the classification of the formulations, the opaque and uniform ones, with intermediate viscosity, compatible with the application on the hair were chosen, guaranteeing acceptance by possible consumers. PLM offered images indicative of highly structured systems, confirmed by the SAXS technique. Rheology indicated that the use of vegetable oils, compared to mineral oil, generated formulations with slightly lower viscosity, allowing the choice of the formulation (12, of the ternary diagram) with higher viscosity among the others. Finally, the determination of the SPF did not indicate the ability to protect against ultraviolet radiation. Thus, in this study, a highly structured formulation, prepared with cationic surfactant and vegetable oils was developed, offering another possibility of an innovative product to consumers of hair cosmetics.

Mycorrhizal status of Coccothrinax crinita (Arecaceae), an endangered endemic species from western Cuba

This study describes the arbuscular mycorrhizal status of Coccothrinax crinita , an endemic endangered palm species native to western Cuba. Habitat destruction and local unregulated exploitation have caused population decline in its natural habitat and, consequently, C. crinita is on the verge of extinction. The survival of this species in stressed environments assumes its association with arbuscular mycorrhizal fungi. The present study was conducted near Las Pozas, a rural community located in Artemisa province, western Cuba. In order to determine the presence of arbuscular mycorrhizal associations in C. crinita , adult plants were selected in their natural habitat, and the roots and rhizosphere soil of the individuals collected. Root colonization percentage values were determined, as well as soil spore density and richness. An Arum - Paris mycorrhizal type was predominant in this species, with abundant coils and dark septate endophytes. Root colonization percentage averaged 60 ± 4.9% and spore density averaged 756 ± 223.33 spores 100 g soil -1 . Sixteen AMF species were found, with a predominance of Glomus . Coccothrinax crinita is associated with AMF, and knowledge of the presence of an arbuscular mycorrhizal interaction in the rhizosphere of this palm is a first step towards its use as a biological tool to optimize cultivation and preservation of the species.
Enhancement of Crystallization Behaviors in Quaternary Composites Containing Biodegradable Polymer by Supramolecular Inclusion Complex

Novel multi-component composites composed of the biodegradable polymer poly(ethylene adipate) (PEA), the water-soluble polymer poly(ethylene oxide) (PEO), poly(vinyl acetate) (PVAc), and a supramolecular-like inclusion complex (IC) made by α-cyclodextrin (α-CD) and poly(ε-caprolactone) (PCL) (coded as PCL–CD–IC) are discussed in this work. The PCL–CD–IC was used to increase the crystallization rate of the miscible PEA/PEO/PVAc ternary blend that crystalized slower than neat PEA. Higher resolution SEM and TEM images displayed that PCL–CD–IC did not assemble notably in the quaternary composites. For the results of isothermal crystallization, the analysis of the Avrami equation demonstrated that the rate constant k increased with the addition of PCL–CD–IC in the composites, suggesting that PCL–CD–IC provided more nucleation sites to promote the crystallization rate. The nucleation density increased with the addition of PCL–CD–IC, and the amount of spherulite also increased. Wide angle X-ray results showed that the composites displayed similar diffraction patterns to neat PEA, meaning PEO, PVAc, and PCL–CD–IC would not change the crystal structures of PEA in the composites. The PCL–CD–IC, the supramolecular nucleation agent, demonstrated its superior ability to enhance the multi-component composites of biodegradable polymer in this study.
Primary cardiac sarcoma: a case report of a therapeutic challenge

Abstract Background Primary cardiac sarcomas are very rare and the prognosis is poor both because the diagnosis is typically made at an advanced stage of the disease and because data are insufficient to identify a standard treatment. Surgical resection is the cornerstone of therapy with the need to develop new therapeutic strategies. Case summary We present a case of a young man admitted to the emergency department due to worsening dyspnoea. A left-sided sarcoma was diagnosed and treated with surgery, chemo- and radiation therapy, and subsequently with heart transplant for local recurrence of the disease. Endomyocardial biopsy made during the routine follow-up period was complicated by pericardial tamponade and cardiogenic shock and the patient was managed with veno-arterial extracorporeal membrane oxygenation, until recovery of left ventricular function (left ventricular ejection fraction of 55%). After 1 year a kidney transplant was performed. After 42 months from diagnosis, the patient is in good general condition. Discussion Primary cardiac sarcomas are treated with surgery to reach R0 (free resection margins) and with chemo- and radiation therapy with adjuvant purposes. Auto-transplantation is also performed, while conventional heart transplant must be customized on an individual basis, after excluding metastases. A multidisciplinary assessment should be performed and the single patient treated with a personalized approach, in relation to his performance status, location of the mass, and stage of the disease.
Roozbeh adult autism spectrum disorder clinic: lessons learned from first 34 cases

Autism Spectrum Disorder (ASD) is a complex heterogeneous clinical entity with many overlaps and comorbidities with other psychiatric and developmental disorders. Adults with ASD lack adequate access to facilities and supports. This article describes the clinical profile of the first 34 patients admitted to Roozbeh adult ASD clinic during a 12-month period. Twenty-eight patients were male, all were single, 22 patients were unemployed and 26 were living with their families of origin. Obsession, inattention and sexual problems were the most common chief complaints. Multifaceted and gender-specific presentations results in misdiagnoses. Knowledge and training of the mental health professionals on adult ASD seem to be seriously inadequate. There is virtually no other specialized clinical and rehabilitation facilitates to help this vulnerable group of patients in Iran
An improved and practical synthesis route to antiproliferative (±)-shikonin and its O-acyl derivatives

Abstract Shikonin and its O-acyl derivatives are attracting increasing levels of attention among medicinal chemists due to their potencies as highly selective cytotoxic agents against cancer cells. However, providing a large number of shikonin-related samples by organic synthesis remains challenging. In the present study, we developed an improved and practical synthesis route to shikonin derivatives by olefin metathesis that has enabled the gram-scale preparation of a prenylated tetramethylnaphthazaline, a key intermediate in the synthesis of shikonin. In addition, a method for the selective cleavage of the acyl protecting groups at the phenolic positions of tri-O-acylated shikonins has been developed that provides concise routes to diverse O-acylshikonin derivatives.
