A. K. GLAZUNOV’S QUARTETS: ATTEMPT AT CRITICAL REVIEW
Authors: Sevost'yanova Liliya Vasil'evna
Published: May 2018

The article is devoted to the critical review of A. K. Glazunov’s quartets. Basing on the statements of B. V. Asafiev and B. L. Yavorsky, as well as on the classification of psychological types by Carl Gustav Jung, the author shows the dominance of extraverted sensation in the psychological world of the quartets. This led to dissolution in objects (traditions of quartets by Rimsky-Korsakov, Borodin, Tchaikovsky and Taneyev) and depreciation of the subjective factor. The quartets by Glazunov are dominated by desire for pleasure, the increased level of aesthetic quality. The cult of beauty, expositional static character, leveling of the development techniques of progress and contrast, and filling of statuary exposition with decorative methods showing signs of secondary character, borrowing from the Kuchkists’ creativity come to the fore. The principles of variation, endowment of the simplest harmonic turns and tonalities with colorful properties, hypertrophy of the principles of the suite character, predominance of centripetalism become omnipresent. As a result, the author comes to the conclusion about gradual depletion of the composer’s creative energy.
CLASS AND LAND RELATIONS IN DAGESTAN IN THE SECOND HALF OF THE XIX - AT THE BEGINNING OF THE XX CENTURY
Authors: Ibragimova Patimat Abdusalamovna
Published: May 2018

The article examines class and land relations in Dagestan in the middle of the XIX century on the eve of the reforms that were carried out by the government, as well as the class structure. The measures of the tsarist government on changing the estate-land system in Dagestan in the XIX century are shown. Relying on archival and other sources the author describes the social and legal status of different categories of the peasantry and class and land relations in certain parts of Dagestan. The paper analyzes the feudal duties, which were performed by dependent peasants in return for land, and land rights of the upper class. Having analyzed documentary sources the author concludes that private (mulk) landownership was widely practiced in Dagestan long before its attachment to Russia.
CONCEPTION OF FORMING SIBERIAN SOCIAL DEMOCRACY IN THE SOVIET HISTORIOGRAPHY
Authors: Isachkin Sergei Pavlovich
Published: May 2018

The article analyzes the conception of forming Siberian social democracy, examines its evolution, peculiarities and contradictions in the Soviet period of domestic historiography. According to the author, in the 1920s - at the beginning of the 1930s the conception acquires its theoretical justification, in the period from the middle of the 1930s to the 1950s its historical concretization occurs, and the 1960-1980s witnessed the integration of its theoretical and specific historical aspects. The author mentions the contribution of certain studies to the development of this conception, identifies negative influence of ideological dogmas on the process of its formation and development.

Teleneurology: Why it Works for Rural Hospitals
Authors: McCormick Talbot
Published: May 2018

The American Academy of Neurology views teleneurology as an effective tool for rapid evaluation of patients in remote locations requiring neurologic care. These underserved locations include geographically isolated rural areas, as well as urban areas with too few available neurology specialists. This article focuses on the problem of stroke worldwide and the penalty imposed on those living in rural areas. Most importantly, the ability to offset those negative factors using teleneurology is illustrated through the real world experience of a rural Oklahoma hospital.

A Physician’s Perspective on What Works (and Doesn’t) for Telemedicine
Authors: Porter Timothy
Published: May 2018

No abstract available.

Editor’s note: As patients start to demand access to telemedicine,1 it is imperative for physicians to understand how to make these types of appointments available in their practice. Without telemedicine adoption as a standard of care, physicians run the risk of losing patients to on-demand telemedicine organizations. Through telemedicine, not only do patients get a more convenient and cost-effective experience, providers have the opportunity to grow their practice and increase patient satisfaction. In this article, Dr. Timothy Porter, a community pediatrician in Chicago, shares his perspective.
Telehealth Governance: An Essential Tool to Empower Today’s Healthcare Leaders
Authors: Arkwright Bryan , Jones Jeff , Osborne Thomas , Glorioso Guy , Russo, Jr. John
Published: May 2018

Strong telehealth governance serves as the cornerstone for advancing a telehealth strategy by ensuring that the health system has the intentional leadership infrastructure to compete and excel in this fast-paced and transforming industry. 

Effective governance is the essential first step towards successful management. The former informs the latter to optimize value to the stakeholders. Paraphrasing the Financial Reporting Council, corporate (telehealth) governance should contribute to better company performance by helping a board discharge its duties in the best interests of stakeholders: executive leadership, management, staff, customers, patients, vendors, communities, and regulators, etc. Good governance facilitates efficient, effective, and entrepreneurial management that can deliver value over the longer term. If ignored, the consequences may be vulnerability or poor performance (Financial Reporting Council, 2008).
A Plea for Critical Changes to the Electronic Medical Record
Authors: Braid M. Ted
Published: May 2018

The electronic medical record (EMR) is significantly more than a digitalized format for converting patient data into easily stored and recalled information. Today, each patient’s EMR is a vast, growing accumulation of health data sourced from physicians and professional medical devices. And, according to HIPAA, it is the absolute property of the patient. At its best, the EMR is a trusted data source that contributes to improved patient care. It is my concern that in its current state and considering existing legislation, the very thing we are building will fall in upon itself long before its potential is realized. It must change or the promise of national access to critical care data in the emergency department (ED), for example, may never be realized.

Authors: Ferk Savec Vesna
Published: May 2018

The article examines the opportunities and challenges for the use of ICT in science education in the light of science teachers’ Technological Pedagogical Content Knowledge (TPACK). Some of the variables that have been studied with regard to TPACK framework in science classrooms (such as teachers' self-efficacy, gender, teaching experience, teachers’ believes, etc.) are reviewed, also variations of TPACK framework specific for science education are elaborated. In conclusion some of the aspects of TPACK in science education that need to be addressed in future are indicated, e.g. the development of subject specific ICT-based resources and e-learning platforms; training to develop science teachers’ integrated skills for the implementation of ICT in their subject teaching; the importance of continuous encouraging of science teachers’ for their participation in in-service training related to the use of ICT; and the examination of the role of science teachers’ TPACK in developing of students’ 21st century trans-disciplinary skills.
Intervencionismo con laminectomía para la Espondilolistesis lumbar degenerativa.
Authors: Nauque Moposita Nelsinio , Alvarado Galarza Graciela , López Brito Diego
Published: May 2018

La Espondilolistesis Degenerativa constituye una afección poco frecuente, pero con un curso inexorable hacia la limitación funcional, caracterizada por el deslizamiento de una vértebra sobre otra hacia adelante con integridad del arco neural. Posee un cuadro clínico de evolución rápida, siendo el nivel más afectado de L4 a L5, provocando una estenosis focal que no excede más del 30% del grosor de la vértebra. A menudo el diagnóstico ha estado obstaculizado por la no especificidad de la sintomatología, y la insuficiencia relacionada con los recursos carentes para exponer diagnósticos apropiados. El presente trabajo posibilitó presentar el caso de una  paciente con síntomas de Espondilolistesis Lumbar Degenerativa diagnosticado en el Hospital General Docente Ambato, Ecuador en el año 2017, con historia de osteoporosis desde hace 5 años e incapacidad funcional progresiva para el desempeño de sus actividades habituales, por lo que se decidió intervencionismo quirúrgico considerando realizar en primera instancia Fusión lumbar la cual resultó fallida por inestabilidad ósea, realizándose en segunda instancia Laminectomía vertebral, evidenciándose que el procedimiento es el tratamiento ideal para tratar afecciones similares máxime en ancianos con osteoporosis, aunque debe valorarse siempre las condiciones generales e individuales de cada paciente.

Authors: Ramos Yánez Diana , Cruz Daniel , Andrade Albán Noemí
Published: May 2018

La Distrofia Muscular de Duchenne (DMD) o Distrofia Muscular Progresiva, es una patología hereditaria con patrón recesivo ligado al cromosoma X, causada por una mutación del gen que codifica la proteína llamada distrofina. Esta alteración genética, conduce a una atrofia muscular proximal, causante de una dificultad progresiva para la deambulación, deformación de la columna vertebral, retraso mental en algunos casos y muerte alrededor de los veinte años de edad por falla cardiopulmonar. Se emprende una revisión bibliográfica de esta patología y por ende el estudio de este caso en particular, con el objetivo de notificar y contribuir en el registro de la prevalencia de esta enfermedad en el Ecuador. Se reporta el caso de un niño de siete años, indígena, proveniente de la parroquia rural Huambaló, perteneciente al cantón Pelileo (provincia de Tungurahua), que acude al Hospital Básico Pelileo por presentar dificultad en la deambulación. Es valorado clínicamente y con un enfoque diagnóstico hacia una enfermedad neuromuscular, se efectúa una serie de exámenes complementarios de imagen, hematométricos y estudio histopatológico. El algoritmo de este estudio ayuda al diagnóstico presuntivo y definitivo de Distrofia Muscular de Duchenne. Sin embargo, al tratarse de una enfermedad genética, el análisis cromosómico tiene gran relevancia y se ve corroborado sus características fenotípicas clásicas conforme a la literatura y evidencias médicas. Sin embargo, resulta necesario, mejorar la calidad de vida de estos pacientes a través del cuidado de un equipo multidisciplinar de salud y el apoyo gubernamental.

Authors: De Araujo Neurauter Anna Luiza , Andrade Albán Noemí
Published: May 2018

Granulomatosis with polyangiitis, a small vessels vasculitis, involves mostly upper respiratory tract, lungs and kidneys. It’s a multisystemic pathology, with no sex predominance, affecting adults over 40 years old. Case report: K.S.D, 64 years, female, came to emergency room with dyspnea, cough and coryza, 15 days after a recurrent acute otitis media surgical treatment. A CT showed bilateral pleural effusion, consolidation and a lung mass, being admitted in Intensive Care Unit. Subsequently, developed mastoiditis and conjunctival hyperemia and used several antibiotic therapys. Patient was discharged 40 days later, with clinical improvement. One month later, was admitted again with pulmonary septic shock, in addition to sinusitis, polyarthralgia, purpura and acute renal injury, requiring hemodyalisis. Biomarkers were requested, such as c-ANCA and rheumatoid factor, with positive result and antinuclear factor, with negative result. A renal biopsy also has been solicitated, showing glomerulonephritis. The diagnosis was granulomatosis with polyangiitis, treated with methylprednisone pulse therapy and cyclophosphamide, progressing to clinical stability and receiving discharge with outpatient follow-up. Conclusion: Granulomatosis with polyangiitis is a rare condition, with that should be considered when patient presents the triad: upper and lower airways and glomerulonephritis. Early diagnosis and immunosuppressive therapy are essential to reduce its morbimortality.

Effects of Organic Manures and Their Combination With Urea On Sweet Pepper Production in the Mid-hills
Authors: Ghimire Suresh , Shakya Santa M , Srivastava Arvind
Published: May 2018

Using excessive chemical fertilizers to combat increasing challenges for food has been creating a serious threat to the environment. To address this contemporary problem field experiments were carried out during March-July, 2010 and February-August, 2011 to evaluate the effect of organic manures and their combination with urea on production of sweet pepper in a randomized complete block design. Farmyard manure, goat manure, vermicompost, their combination with urea, and inorganic fertilizers alone were used as treatments based on fulfillment of required nitrogen (150 Kg/ha) for the crop. The results showed that application of FYM-50%+urea-50% gave the highest fruit set (45.7%) and took least number of days (49.67 days) to first flowering. Weight per fruit was the highest (98.30 g) with FYM-50%+urea-50% followed by vermicompost-100% (94.52 g). The highest fruit yield (13.53 t/ha) was recorded with FYM-50%+urea-50% followed by goat manure- 100% (11.95 t/ha), both being at par. Physiological weight loss was the highest (16.4%) with inorganic fertilizers and was the lowest (6.7%) with goat manure 100%.
Analysis of Perception and Adaptation to Climate Change by Farmers in Gulmi District, Nepal
Authors: Ghimire Narhari P , Aryal Maniratna
Published: May 2018

Climate change is a global challenge, highly affecting the developing countries with low adapting capacity, of which Nepal is not an exception. Climate change highly affects agriculture and livelihoods of farmers in Nepal. Its objectives are farmer's perceptions, witnesses and experiences on effects of climate change on agriculture and adaptations by farmers. Primary informations collected through structured questionnaire of household survey by selecting samples randomly. Information on primary and secondary data sources verified scientifically by trend analysis of climatic data. Most farmers depending on subsistence agriculture have a perception of climate change and respond to the changes based on their own local knowledge and experiences on farming. They are practicing both agricultural and non-agricultural adaptations at individual level. Consequently, appropriate technologies and sustainable community based adaptation strategies built on farmers knowledge, experiences and situation to cope with increasing effects of climate change on agriculture are necessary in the coming years.
Evaluation of Antagonistic Plant Materials to Control Southern Root Knot Nematode in Tomato
Authors: Kafle Arun
Published: May 2018

Marigold ((Tagetes patula), crotalaria (Crotalaria juncia), rapeseed plant (Brassica rapa) and oat (Avena sativa) as antagonistic plant and tomato (Lycopersicon esculentum), CL1104 variety as control, were evaluated to determine the effect on southern root knot nematode population in pot experiment at Tsukuba, Japan in year 2010. Completely Randomized Design (CRD) with three replications was used. Initial juvenile population was 30.0±2.8 per 20g soil. The juvenile nematode population was counted 63 days after transplanting and biomass of plants was incorporated in soil. Population was again counted 11 days and 13 day after biomass incorporation. At final count of Juvenile nematode population, it was found highest in tomato (66.6 /20g soil). Highest control was achieved in marigold (2.3 juvenile/20g soil) followed by crotalaria (3.0 juvenile/20g soil. Marigold and crotalaria followed by oat in rotation with tomato were observed as best antagonist plants to control Southern root knot nematode.
Reflections on Sven-Eric Liedman’s Marx-Biography “A World to Win: The Life and Works of Karl Marx”
Authors: Fuchs Christian
Published: May 2018

The English translation of Sven-Eric Liedman’s Marx-biography A World to Win: The Life and Works of Karl Marx was published two weeks before Marx’s bicentenary. This article presents reflections on Liedman’s book and asks how one should best write biographically about Marx. The paper compares Liedman’s biography to the Marx-biographies written by Jonathan Sperber (Karl Marx: A Nineteenth-Century Life) and Gareth Stedman-Jones (Karl Marx: Greatness and Illusion). A biography is a way of repeating a person’s life, works and age in a process of reconstruction and retelling. The question that arises is how to write a biography as a dialectical text.

Synthesis Wanted: Reading Capital After 20th Century Orthodoxies and Revisions
Authors: Schmidt Ingo
Published: May 2018

The article distinguishes between revisionist and orthodox readings of Capital and identifies two waves of innovations in Marxist political economy. The first produced the classical theories of imperialism; the second produced a diversity of Neo-Marxisms and new orthodoxies sowing the seeds for the 1000 Marxisms developing in the age of neoliberal globalisation. Reading all of these approaches to Marxist Political Economy in context, the article suggests and offers a key to the understanding of capitalist development and socialist movements in the 20th century. Using them as background for a new reading of Capital also allows an understanding of contemporary capitalism and considerations of socialist futures.
Intrinsic development of choroidal and thalamic collaterals in hemorrhagic-onset moyamoya disease: case-control study of the Japan Adult Moyamoya Trial
Authors: Fujimura Miki , Funaki Takeshi , Houkin Kiyohiro , Takahashi Jun C. , Kuroda Satoshi , Tomata Yasutake , Tominaga Teiji , Miyamoto Susumu
Published: May 2018

OBJECTIVE

This study was performed to identify the angiographic features of hemorrhagic-onset moyamoya disease (MMD) in comparison with those of patients with ischemic-onset MMD.

METHODS

This case-control study compared the data set of the Japan Adult Moyamoya (JAM) Trial with the angiographic data of adult patients with ischemic-onset MMD. The authors analyzed angiograms obtained at onset, classifying the collaterals into 3 subtypes: lenticulostriate anastomosis, thalamic anastomosis, and choroidal anastomosis. They then compared the extent of these collaterals, as indicated by the collateral development grade from 0 to 2 in each subtype, between the JAM Trial group and the ischemic-onset group. They also compared the involvement of the posterior cerebral artery (PCA) and Suzuki’s angiographic staging between each group.

RESULTS

Among 89 ischemic-onset patients, 103 symptomatic hemispheres in 80 patients were analyzed and compared with 75 hemorrhagic hemispheres from the JAM Trial. The hemorrhagic-onset patients showed a significantly higher proportion of thalamic anastomosis (p = 0.043) and choroidal anastomosis (< 0.001), as indicated by grade 2 in each subtype, compared with ischemic-onset patients. Suzuki’s angiographic staging was significantly higher in the hemorrhagic group (< 0.038). There was no difference in the extent of lenticulostriate anastomosis and PCA involvement between the groups.

CONCLUSIONS

In adult MMD, the characteristic pattern of the abnormal vascular networks at the base of the brain is different between each onset type. In light of the more prominent development of thalamic and choroidal anastomosis in the JAM Trial group in the present study, development of these collaterals, especially the choroidal collateral extending beyond the lateral ventricle, may play a critical role in hemorrhagic presentation in MMD.

Authors: Daou Badih , Atallah Elias , Chalouhi Nohra , Starke Robert M. , Oliver Jeffrey , Montano Maria , Jabbour Pascal , Rosenwasser Robert H. , Tjoumakaris Stavropoula I.
Published: May 2018

OBJECTIVE

The Pipeline embolization device (PED) has become a valuable tool in the treatment of cerebral aneurysms. Although failures with PED treatment have been reported, the characteristics and course of these aneurysms remain a topic of uncertainty.

METHODS

Electronic medical records and imaging studies were reviewed for all patients treated with the PED between July 2010 and March 2015 to identify characteristics of patients and aneurysms with residual filling after PED treatment.

RESULTS

Of 316 cases treated at a single institution, 281 patients had a long-term follow-up. A total of 52 (16.4%) aneurysms with residual filling were identified and constituted the study population. The mean patient age in this population was 58.8 years. The mean aneurysm size was 10.1 mm ± 7.15 mm. Twelve aneurysms were fusiform (23%). Of the aneurysms with residual filling, there were 20 carotid ophthalmic (CO) aneurysms (20% of all CO aneurysms treated), 10 other paraclinoid aneurysms (16.4% of all paraclinoid aneurysms), 7 posterior communicating artery (PCoA) aneurysms (21.9% of all PCoA aneurysms), 7 cavernous internal carotid artery (ICA) aneurysms (14.9% of all cavernous ICA aneurysms), 4 vertebrobasilar (VB) junction aneurysms (14.8% of all VB junction aneurysms), and 3 middle cerebral artery (MCA) aneurysms (25% of all MCA aneurysms). Eleven patients underwent placement of more than one PED (21.2%), with a mean number of devices of 1.28 per case. Eight of 12 aneurysms were previously treated with a stent (15.4%). Nineteen patients underwent re-treatment (36.5%); the 33 patients who did not undergo re-treatment (63.5%) were monitored by angiography or noninvasive imaging. In multivariate analysis, age older than 65 years (OR 2.65, 95% CI 1.33–5.28; p = 0.05), prior stent placement across the target aneurysm (OR 2.94, 95% CI 1.15–7.51; p = 0.02), aneurysm location in the distal anterior circulation (MCA, PCoA, and anterior choroidal artery: OR 2.72, 95% CI 1.19–6.18; p = 0.017), and longer follow-up duration (OR 1.06, 95% CI 1.03–1.09; p < 0.001) were associated with incomplete aneurysm occlusion.

CONCLUSIONS

While the PED can allow for treatment of large, broad-necked aneurysms with high efficacy, treatment failures do occur (16.4%). Aneurysm size, shape, and previous treatment may influence treatment outcome.
Pipeline embolization of posterior circulation aneurysms: a multicenter study of 131 aneurysms

Published: May 2018

OBJECTIVE

Flow diversion for posterior circulation aneurysms performed using the Pipeline embolization device (PED) constitutes an increasingly common off-label use for otherwise untreatable aneurysms. The safety and efficacy of this treatment modality has not been assessed in a multicenter study.

METHODS

A retrospective review of prospectively maintained databases at 8 academic institutions was performed for the years 2009 to 2016 to identify patients with posterior circulation aneurysms treated with PED placement.

RESULTS

A total of 129 consecutive patients underwent 129 procedures to treat 131 aneurysms; 29 dissecting, 53 fusiform, and 49 saccular lesions were included. At a median follow-up of 11 months, complete and near-complete occlusion was recorded in 78.1%. Dissecting aneurysms had the highest occlusion rate and fusiform the lowest. Major complications were most frequent in fusiform aneurysms, whereas minor complications occurred most commonly in saccular aneurysms. In patients with saccular aneurysms, clopidogrel responders had a lower complication rate than did clopidogrel nonresponders. The majority of dissecting aneurysms were treated in the immediate or acute phase following subarachnoid hemorrhage, a circumstance that contributed to the highest mortality rate in those aneurysms.

CONCLUSIONS

In the largest series to date, fusiform aneurysms were found to have the lowest occlusion rate and the highest frequency of major complications. Dissecting aneurysms, frequently treated in the setting of subarachnoid hemorrhage, occluded most often and had a low complication rate. Saccular aneurysms were associated with predominantly minor complications, particularly in clopidogrel nonresponders.
Sublaminar fixation for traumatic lumbar fracture subluxation with lateral listhesis in a 2-year-old patient
Authors: Yanni Daniel S. , Cruz Aurora S. , Halim Alexander Y. , Gill Amandip S. , Muhonen Michael G. , Heary Robert F. , Goldstein Ira M.
Published: May 2018

Pediatric spinal trauma can present a surgeon with difficult management decisions given the rarity of these cases, pediatric anatomy, and a growing spine. The need to stabilize a traumatically unstable pediatric spine can be an operative challenge given the lack of instrumentation available. The authors present a surgical technique and an illustrative case that may offer a novel, less disruptive method of stabilization. A 2-year-old girl presented after an assault with an L1–2 fracture subluxation with lateral listhesis and fractured jumped facets exhibited on CT scans. CT also showed intact growth plates at the vertebral body, pedicles, and posterior elements. MRI showed severe ligamentous injury, conus medullaris compression, and an epidural hematoma. Neurologically, the patient moved both lower extremities asymmetrically. Given the severity of the deformity and neurological examination and disruption of the stabilizing structures, the authors made the decision to surgically decompress the L-1 and L-2 segments with bilateral laminotomies, evacuate the epidural hematoma, and reduce the deformity with sublaminar stabilization using braided polyester cables bilaterally, thus preserving the growth plates. They also performed a posterolateral onlay fusion at L-1 and L-2 using autograft and allograft placed due to the facet disruption. At the 42-month follow-up, imaging showed fusion of L-1 and L-2 with good alignment, and the hardware was subsequently explanted. The patient was neurologically symmetric in strength, ambulating, and had preserved alignment. Her bones and spinal canal continued to grow in relation to the other levels.
Chronic encapsulated intraventricular hematoma in a pediatric patient: case report
Authors: Wetzel Jeremy , Bray David , Wrubel David
Published: May 2018

Chronic encapsulated intraventricular hematoma (CEIVH) is a rare, intraventricular, nonneoplastic mass lesion that can become symptomatic from mass effect or obstructive hydrocephalus. Only 5 cases have been reported in the literature, and only one of these occurred in a pediatric patient and dates back to the pre–modern neuroimaging and pre-microsurgical era of neurosurgery. Imaging features can mimic those of many more common intraventricular lesions, such as choroid plexus tumors or cavernous malformations. In all reported symptomatic cases, resection was safely performed and led to a cure and symptom resolution. Here, the authors present a case of CEIVH in a pediatric patient, describe the operative techniques of resection, review the available literature, and discuss current understanding of the pathophysiology, making this the most comprehensive report on this disease entity to date. The case is a 14-year-old boy who presented with headaches and emesis. Computed tomography showed a hyperdense mass in the trigone of the right lateral ventricle. Magnetic resonance imaging showed a contrast-enhancing well-circumscribed mass. Right temporal craniotomy utilizing a posterior middle temporal gyrus transcortical approach was performed, and gross-total resection was achieved. Pathology revealed a CEIVH. The boy’s postoperative course was uncomplicated, and he was discharged 2 days after surgery.

There is considerable interest in constructing succinct programs and much debate over which languages are most expressive. However, such debates tend to revolve around syntactic notions of program size and language constructs, without considering the complex interrelations of syntax, semantics, and implementation.

We hypothesise that languages with larger semantics have more succinct programs. To explore this, we have conducted an empirical study of the expressive properties of Turing and Random Access Stored Program machines, taking into account their Structural Operational Semantics, universal machines, implementations in each other, and physical realisations as Field Programmable Gate Arrays (FPGAs). We conclude that our intuitions about the relationship between the expressiveness of a language and the typical succinctness of programs are largely correct. We also conclude that the information content of abstract models of computations is a good indicator of the component count for FPGA realisations.

Published: May 2018

Rough set theory and neutrosophic set theory are mathematical models to deal with incomplete and vague information. These two theories can be combined into a framework for modeling and processing incomplete information in information systems. Thus, the neutrosophic rough set hybrid model gives more precision, flexibility and compatibility to the system as compared to the classic and fuzzy models. In this research study, we develop neutrosophic rough digraphs based on the neutrosophic rough hybrid model. Moreover, we discuss regular neutrosophic rough digraphs, and we solve decision-making problems by using our proposed hybrid model. Finally, we give a comparison analysis of two hybrid models, namely, neutrosophic rough digraphs and rough neutrosophic digraphs.

Over the last years, inulin, a fructan mixture consisting of oligosaccharides and polysaccharides, has attracted more and more attention from both food industry and researchers, due to its unique functional properties as a natural resource. Therefore, there is an increased interest in the extraction and quantification of inulin for its valorization from inulin rich plants, wastes and by-products. In this work, ultrasonic treatment was applied for inulin extraction, observing a great impact of extraction temperature and ultrasonic power on the inulin content in the obtained extracts. A combined process including trifluoroacetic acid (TFA)-assisted hydrolysis and analysis with high performance liquid chromatography equipped with evaporative light scattering detector (HPLC-ELSD) was developed to quantify inulin content. The effect of hydrolysis parameters was investigated, obtaining the optimal conditions after using TFA at a concentration of 1 mg/mL, hydrolysis temperature of 90 °C, and hydrolysis duration of 60 min. The good linearity (>0.995), precision, recovery (100.27%), and stability obtained during the validation process showed that this developed method allows the quantification of total inulin content in the samples analyzed. This combined method may also contribute to the investigation of the functional properties of inulin (e.g., as prebiotic).

Authors: Garcia-Aunon Pablo , Barrientos Cruz Antonio
Published: May 2018

The search of a given area is one of the most studied tasks in swarm robotics. Different heuristic methods have been studied in the past taking into account the peculiarities of these systems (number of robots, limited communications and sensing and computational capacities). In this work, we introduce a behavioral network made up of different well-known behaviors that act together to achieve a good performance, while adapting to different scenarios. The algorithm is compared with six strategies based on movement patterns in terms of three performance models. For the comparison, four scenario types are considered: plain, with obstacles, with the target location probability distribution and a combination of obstacles and the target location probability distribution. For each scenario type, different variations are considered, such as the number of agents and area size. Results show that although simplistic solutions may be convenient for the simplest scenario type, for the more complex ones, the proposed algorithm achieves better results.

Published: May 2018

Purpose: Although the protective effect of social support against depression is well known, limited information exists on racial differences in this association. The current study examined Black-White differences in the effects of religious and secular emotional social support on depressive symptoms in a national sample of older adults in the United States. Methods: With a longitudinal prospective design, the Religion, Aging and Health Survey, 2001–2004, followed 1493 Black (n = 734) and White (n = 759) elderly individuals (age 66 and older) for three years. Race, demographics (age and gender), socio-economics (education and marital status) and frequency of church attendance were measured at baseline in 2001. Secular social support, religious social support, chronic medical conditions and depressive symptoms [8- item Center for Epidemiological Studies-Depression scale (CES-D)] were measured in 2004. Multiple linear regression models were used for data analysis. Results: In the pooled sample, secular and religious social support were both protective against depressive symptoms, net of all covariates. Race interacted with secular (β = −0.62 for interaction) and religious (β = −0.21 for interaction) social support on baseline depressive symptoms (p < 0.05 for both interactions), suggesting larger protections for Blacks compared to Whites. In race-specific models, the regression weight for the effect of secular social support on depressive symptoms was larger for Blacks (β = −0.64) than Whites (β = −0.16). Conclusion: We found Black—White differences in the protective effects of secular and religious social support against depressive symptoms. Blacks seem to benefit more from the same level of emotional social support, regardless of its source, compared to Whites.

Published: May 2018

In this paper, the Hummer’s method was used to prepare the compound catalyst of reduced graphene and TiO2 (RGO-P25), and the sand core plate was used as the carrier to provide the theoretical basis for the application of animal environmental purification by exploring the degradation of ammonia in RGO-P25. Characterization results show that the band gap of P25 is reduced from 3.14 eV to 2.96 eV after the combination of RGO, and the recombination rate of the photogenerated electrons and holes also decreased significantly, both resulting in the improvement of ammonia degradation by composite catalysts. Experimental results show that the carrier (sand core plate) and RGO-P25 are effectively stabilized with Si–O–Ti, but the blank core plate carrier could not degrade the ammonia, and its adsorption is not obvious, only 5% ± 1%, under 300 W ultraviolet lamp irradiation, the degradation rates of P25, RGO and RGO-P25 for ammonia at initial concentrations of 119–124 ppm were 72.25%, 81.66% and 93.64%, respectively. P25 dispersed through RGO can effectively adsorb ammonia on the surface to provide a reaction environment and thereby improve its photocatalytic efficiency, thus, endowing the RGO-P25 composites with higher photocatalytic degradation performance than RGO or P25 individually.
Lyapunov Exponents of a Discontinuous 4D Hyperchaotic System of Integer or Fractional Order
Authors: Danca Marius-F.
Published: May 2018

In this paper, the dynamics of local finite-time Lyapunov exponents of a 4D hyperchaotic system of integer or fractional order with a discontinuous right-hand side and as an initial value problem, are investigated graphically. It is shown that a discontinuous system of integer or fractional order cannot be numerically integrated using methods for continuous differential equations. A possible approach for discontinuous systems is presented. To integrate the initial value problem of fractional order or integer order, the discontinuous system is continuously approximated via Filippov’s regularization and Cellina’s Theorem. The Lyapunov exponents of the approximated system of integer or fractional order are represented as a function of two variables: as a function of two parameters, or as a function of the fractional order and one parameter, respectively. The obtained three-dimensional representation leads to comprehensive conclusions regarding the nature, differences and sign of the Lyapunov exponents in both integer order and fractional order cases.

Different transforms used in binding a secret key to correlated physical-identifier outputs are compared. Decorrelation efficiency is the metric used to determine transforms that give highly-uncorrelated outputs. Scalar quantizers are applied to transform outputs to extract uniformly distributed bit sequences to which secret keys are bound. A set of transforms that perform well in terms of the decorrelation efficiency is applied to ring oscillator (RO) outputs to improve the uniqueness and reliability of extracted bit sequences, to reduce the hardware area and information leakage about the key and RO outputs, and to maximize the secret-key length. Low-complexity error-correction codes are proposed to illustrate two complete key-binding systems with perfect secrecy, and better secret-key and privacy-leakage rates than existing methods. A reference hardware implementation is also provided to demonstrate that the transform-coding approach occupies a small hardware area.

In a radial distribution network integrated with distributed generation (DG), frequency and voltage instability could occur due to grid disconnection, which would result in an islanded network. This paper proposes an optimal load shedding scheme to balance the electricity demand and the generated power of DGs. The integration of the Firefly Algorithm and Particle Swarm Optimization (FAPSO) is proposed for the application of the planned load shedding and under frequency load shedding (UFLS) scheme. In planning mode, the hybrid optimization maximizes the amount of load remaining and improves the voltage profile of load buses within allowable limits. Moreover, the hybrid optimization can be used in UFLS scheme to identify the optimal combination of loads that need to be shed from a network in operation mode. In order to assess the capabilities of the hybrid optimization, the IEEE 33-bus radial distribution system and part of the Malaysian distribution network with different types of DGs were used. The response of the proposed optimization method in planning and operation were compared with other optimization techniques. The simulation results confirmed the effectiveness of the proposed hybrid optimization in planning mode and demonstrated that the proposed UFLS scheme is quick enough to restore the system frequency without overshooting in less execution time.

Published: May 2018

Short-term load forecasting is an important task for the planning and reliable operation of power grids. High-accuracy forecasting for individual customers helps to make arrangements for generation and reduce electricity costs. Artificial intelligent methods have been applied to short-term load forecasting in past research, but most did not consider electricity use characteristics, efficiency, and more influential factors. In this paper, a method for short-term load forecasting with multi-source data using gated recurrent unit neural networks is proposed. The load data of customers are preprocessed by clustering to reduce the interference of electricity use characteristics. The environmental factors including date, weather and temperature are quantified to extend the input of the whole network so that multi-source information is considered. Gated recurrent unit neural networks are used for extracting temporal features with simpler architecture and less convergence time in the hidden layers. The detailed results of the real-world experiments are shown by the forecasting curve and mean absolute percentage error to prove the availability and superiority of the proposed method compared to the current forecasting methods.
