Assessment of Parkinson's disease progression using neural network and ANFIS models

Patients suffering from Parkinson's disease must periodically undergo a series of tests, usually performed at medical facilities, to diagnose the current state of the disease. Parkinson's disease progression assessment is an important set of procedures that supports the clinical diagnosis. A common part of the diagnostic train is analysis of speech signal to identify the disease specific communication issues. This contribution describes two types of computational models that map speech signal measurements to clinical outputs. Speech signal samples were acquired through measurements from patients suffering from Parkinson's disease. In addition to direct mapping, the developed systems must be able of generalization so that correct clinical scale values can be predicted from future, previously unseen speech signals. Computational methods considered in this paper are artificial neural networks, particularly feedforward networks with several variants of backpropagation learning algorithm, and adaptive network based fuzzy inference system (ANFIS) In order to speed up the learning process, some of the algorithms were parallelized. Resulting diagnostic system could be implemented in an embedded form to support individual assessment of Parkinson's disease progression from patients' homes.
AI based methodology of integrating affective design, engineering, and marketing for defining design specifications of new products
Venue: Eng. Appl. Artif. Intell.

In the early stage of product design, particularly for consumer products, affective design, engineering, and marketing issues must be taken into considerationand they are commonly performed respectively by product designers, engineers, and marketing personnel. However, they have different concerns and focuses with regard to the new product design. Thus, these three processes are commonly conducted separately, leading to a sub optimal and even sub standard design. Such scenario indicates the need to incorporate the concerns of the three processes in the early stage of product design. However, no study has explored the incorporation of the concerns of the three processes into the product design. In this paper, an artificial intelligence (AI) based methodology for integrating affective design, engineering, and marketing for defining design specifications of new products is proposed by which the concerns of the three processes can be considered simultaneously in the early design stage. The proposed methodology mainly involves development of customer satisfaction and cost models using fuzzy regression, generation of product utility functions using chaos based fuzzy regression, formulation of a multi objective optimization model and its solving using a non dominated sorting genetic algorithm II (NSGA II) A case study was conducted for electric iron design to evaluate the effectiveness of the proposed methodology.
Reformulation, fortification and functionalization: Big Food corporations' nutritional engineering and marketing strategies

In response to health concerns arising from the consumption of highly processed foods, the world's largest food and beverage manufacturing corporations (i.e. 'Big Food' have responded by modifying their existing products and introducing new products with 'improved' nutrient profiles. Three distinct strategies used by food corporations to nutritionally engineer and market their products will be identified: the reformulation of foods to reduce levels of harmful food components, the micronutrient fortification of products to address micronutrient deficiencies, and the functionalization of products that claim to provide optimal nutrition and health benefits. These nutritional strategies gain scientific legitimacy by drawing upon the dominant nutritional ideology of 'nutritionism' which is characterized by a reductive focus on nutrients as a way of understanding a food's effects on dietary health. Food and beverage corporations promote these nutritional strategies as an important part of their corporate social responsibility agendas, and as evidence that they are addressing the health issues associated with both over nutrition and under nutrition. However, these corporations are also using these nutritional strategies to legitimize and grow the markets for their products in the global North and South.
Transient Stability Improvement Using UPFC SMES in A Multi Machine Power System

Unified Power Flow Controller (UPFC) is a Voltage sourced converter based Flexible A.C.Transmission (FACTS) controller which has a capability of simultaneously or selectively controlling all the parameters affecting transmission of power. With emphasis on harnessing renewable energy many energy storage technologies are being used. Superconducting magnetic energy storage (SMES) stores energy in magnetic form by means of a D.C. current circulating in a superconducting coil. To exchange power with SMES a power electronic interface is required. Feasibility of interfacing SMES to D.C. link of UPFC has been explored in this paper. A multimachine system with a long transmission line is compensated by UPFC SMES .A DC DC chopper modulates power of SMES so as to improve the transient stability of system. Complete simulation has been done using MATLAB/Simulink which shows improvement of first peak, damping of oscillations improvement in critical clearing time.
An Analysis of Transient Stability Enhancement Capability of UPFC in a Multi machine Power System

This study presents the transient stability enhancement capability of Unified power flow controller (UPFC) as an effective Flexible AC Transmission System (FACTS) device in a multi machine power system. The test system was a reduced Nigerian 330kV power system and the focus was on the effect of disturbances on the largest generating unit (Egbin) in the system. The analysis was conducted by simulating a 3 phase fault at two locations; on the terminal of the largest generator unit at Egbin bus and the bus with the largest load at Ikeja west. The response of the system in both cases was compared with and without the device in operation. Simulations were carried out using the Power System Simulation for Engineering (PSS/E) software. Results showed that, with the UPFC in the network, system transient stability was enhanced considering that critical clearing time of the system was increased from 380ms to 590ms when the fault was at Egbin generator terminal and from 470ms to 510ms following the fault at Ikeja west. In addition, the device was able to damp power oscillations resulting from the disturbance created by the faults.
Alcohol and Obesity: A Dangerous Association for Fatty Liver Disease
Venue: Digestive Diseases

Alcoholic liver disease (ALD) and nonalcoholic fatty liver disease (NAFLD) are the most frequent chronic liver disorders, and their advanced forms alcoholic steatohepatitis and nonalcoholic steatohepatitis are the most frequent conditions leading to liver cirrhosis and hepatocellular carcinoma worldwide. NAFLD is considered as the hepatic manifestation of the metabolic syndrome. With the pandemic rise of obesity, the incidence of NAFLD is also further increasing, and considering the life style in modern societies, there is a significant overlap of (risk factors causing) NAFLD and (alcohol consumption predisposing for) ALD at least in Western countries. Epidemiological studies propose a causative link between chronic alcohol consumption and progressive liver disease in obese individuals. Furthermore, experimental studies indicate combined pathological effects of alcohol and obesity or fatty acid levels, respectively, on hepatocellular lipid accumulation and injury as well as hepatic inflammation, fibrosis and cancerogenesis. Notably, these combined pathological effects are in part additive but partly even synergistic. And importantly, alcohol does already exhibit synergistic pathological effects with obesity at moderate doses. This indicates significant differences in the dose threshold for hepatotoxic alcohol effects in lean and obese subjects and herewith also has important implications for recommendations for 'safe' alcohol consumption. The purpose of this brief review is to update the knowledge on the combined effects of alcohol and obesity on the development and progression of liver disease. Undoubtedly, alcohol and the metabolic syndrome appear as a dangerous mix, and there are important interactive effects of either condition with regard to crucial triggers of liver injury.
Exploring consumers' impulse buying behavior on social commerce platform: The role of parasocial interaction
Venue: Int. J. Inf. Manag.

Task related features affect perceived usefulness.Mood related features affect perceived enjoyment.Social relevant features determine users' parasocial interaction (PSI).PSI affects impulse buying tendency.Perceived enjoyment and impulse buying tendency affect urge to buy impulsively. Social commerce, a recent branch of e commerce, has made the experience of consumers on social commerce platform (SCP) different from other contexts, as the consumers have social interactions with each other. Growing evidence also shows that consumers on these platforms are prone to impulse buying behavior owing to the social interactions. However, existing research on online impulse buying was limited when illustrating the behavior of consumers on SCPs as social relationship constructs were not included. New theoretical developments are needed in regard to fill the research gap. In this research, parasocial interaction (PSI) theory is introduced in this research to examine the influence of social relationship factors on the formation of impulse buying behavior. An empirical research has been conducted on Mogujie (www.mogujie.com) one of the most popular image sharing SCPs in China. Results indicate that PSI exerts an impact on impulse buying tendency, the social relevant features of the SCP determine PSI, and perceived usefulness and PSI both significantly affect perceived enjoyment. In addition, consumers' perceived enjoyment and impulse buying tendencies significantly affect their urge to buy impulsively. The implications, limitations, and discussions are provided.
Hear and Be Heard: Learning With and Through Music as a Dialogical Space for Co Creating Youth Led Conflict Transformation

Israeli, Palestinian, and Palestinian Israeli youth who experience the recreation of protracted conflict in a multiplicity of ways through direct and non direct violence, in addition to intergroup systemic injustice, must learn to witness, name, challenge, and disrupt these extremely powerful societal forces as a means to transform conflict. Transferable learning, in the form of learning for and about peacebuilding, coexistence, coresistence, solidarity, human rights, nonviolent communication, and resilience, when interwoven into the process of learning music with a critical pedagogy (Freire, 1970) can create an opening of spaces (Allsup, 2013) and perspectives in which youth can build equal social relationships. It is my belief through my own engagement with theory and practice while working with youth in locations of systemic injustice and locations of protracted conflict in Israel/Palestine with the music education conflict transformation nonprofit Heartbeat, that musical spaces can have profound and enduring effects on youth and their communities. Within these musical spaces in which ensembles learn, rehearse, and co write lyrics and melodies in dialogue and as reflections of their daily experiences, youth have the potential to author and re author themselves through a creative process of musicking (Small, 1995) This location of possibilities (hooks, 1994) where youth can question and challenge their socialization, serves as an opening "to read their world" (Greene, 1995) develop critical thinking, and to reimagine their role in society as active participants and stakeholders in transforming conflict. This article also includes excerpts weaved throughout from the youth voices of Heartbeat in the form of their lyrics and actual stories of practice. Ultimately, how can Israeli and Palestinian youth musicians author and re author themselves through being heard and co creating musically within these shared dialogical musical spaces, enabling the generating and regenerating of equal social relationships?
Dynamic observations of welding phenomena and finite element analysis in high frequency electric resistance welding

High frequency electric resistance welding (hereinafter referred to as HFW) pipes and tubes are used for high grade line pipes. To cope with the high need for weld seam reliability, the clarification of welding phenomena is important. To clarify the HFW phenomena, at first we developed a HFW simulation system by using electromagnetic, heat conductive and elastic plastic finite element analysis (FEA) methods. Continuous electromagnetic and heat conduction analysis was conducted by subdividing the cross section containing the electrode and the welding point into a large number of two dimensional models. The temperature distribution in the HFW pipe welding procedure can be successfully simulated by this system. The deformation behaviour in which a portion of the weld rises to the inner and outer surfaces as the result of pressurization from welding rolls can be analysed with this system. Secondly, HFW phenomena have been visualized dynamically using a high speed video camera technique. The high intensity part visualized by high speed images has good accordance with the temperature distribution of the FEA result. High speed images have visualized the dynamic phenomena of molten metal flow and sputtering of molten steel. Very rapid movement of molten metal in the forming direction along the welding line was observed at the V convergence point with a speed of 2 50 m s 1, which was far faster than the welding speed. This rapidly moved molten metal generated the peculiar sputtering which spread the molten metal particles as describing an arc perpendicular to the welding line. These phenomena were assumed to be caused by the electromagnetic force concerning the molten steel at the V convergence point.
Variability of disease activity in patients treated with ranibizumab for neovascular age related macular degeneration
Venue: Eye

PurposeTo analyze choroidal neovasularization (CNV) activity and recurrence patterns in patients with neovascular age related macular degeneration (nAMD) treated with ranibizumab, and the correlation with individual intraocular vascular endothelial growth factor (VEGF) suppression time (VST).MethodsPost hoc analysis of data from a prospective, non randomized clinical study. Patients with nAMD treated with ranibizumab on a pro re nata regimen. Disease activity was analyzed monthly by spectral domain optical coherence tomography and correlated with VSTs.ResultsOverall, 73 eyes of 73 patients were included in the study with a mean follow up of 717 days (range: 412 1239 days) Overall, the mean CNV activity free interval was 76.5 days (range: 0 829 days) The individual range of the length of dry intervals was high. A total of 42% of patients had a range of more than 90 days. Overall, 16% of patients showed persistent activity. And 12% stayed dry after the initial ranibizumab treatment. No significant correlation was found between the CNV recurrence pattern and VST (P=0.12).ConclusionsCNV activity in nAMD is irregular, which is reflected in the range of the duration of dry intervals and late recurrences. The biomarker VST solely seems not to be sufficient to explain recurrence pattern of CNV in all AMD patients.
Sound Exposure During Outdoor Music Festivals
Venue: Noise health

Most countries have guidelines to regulate sound exposure at concerts and music festivals. These guidelines limit the allowed sound pressure levels and the concert/festival's duration. In Norway, where there is such a guideline, it is up to the local authorities to impose the regulations. The need to prevent hearing loss among festival participants is self explanatory, but knowledge of the actual dose received by visitors is extremely scarce. This study looks at two Norwegian music festivals where only one was regulated by the Norwegian guideline for concert and music festivals. At each festival the sound exposure of four participants was monitored with noise dose meters. This study compared the exposures experienced at the two festivals, and tested them against the Norwegian guideline and the World Health Organization's recommendations. Sound levels during the concerts were higher at the festival not regulated by any guideline, and levels there exceeded both the national and the Worlds Health Organization's recommendations. The results also show that front of house measurements reliably predict participant exposure.
A ten year global record of absorbing aerosols above clouds from OMI's near UV observations
Venue: SPIE Asia Pacific Remote Sensing

Aerosol cloud interaction continues to be one of the leading uncertain components of climate models, primarily due to the lack of an adequate knowledge of the complex microphysical and radiative processes associated with the aerosolcloud system. The situations when aerosols and clouds are found in the same atmospheric column, for instance, when light absorbing aerosols such as biomass burning generated carbonaceous particles or wind blown dust overlay low level cloud decks, are commonly found over several regional of the world. Contrary to the cloud free scenario over dark surface, for which aerosols are known to produce a net cooling effect (negative radiative forcing) on climate, the overlapping situation of absorbing aerosols over cloud can potentially exert a significant level of atmospheric absorption and produces a positive radiative forcing at top of atmosphere. The magnitude of direct radiative effects of aerosols above cloud depends directly on the aerosol loading, microphysical optical properties of the aerosol layer and the underlying cloud deck, and geometric cloud fraction. We help in addressing this problem by introducing a novel product of optical depth of absorbing aerosols above clouds retrieved from near UV observations made by the Ozone Monitoring Instrument (OMI) on board NASA's Aura platform. The presence of absorbing aerosols above cloud reduces the upwelling radiation reflected by cloud and produces a strong 'color ratio' effect in the near UV region, which can be unambiguously detected in the OMI measurements. Physically based on this effect, the OMACA algorithm retrieves the optical depths of aerosols and clouds simultaneously under a prescribed state of atmosphere. The algorithm architecture and results from a ten year global record including global climatology of frequency of occurrence and above cloud aerosol optical depth, and a discussion on related future field campaigns are presented.
Theories in Business and Information Systems Engineering
Venue: Bus. Inf. Syst. Eng.

Even though the idea of science enjoys an impressive reputation, there seems to be no precise conception of science. On the one hand, there is no unified definition of the extension of activities subsumed under the notion of science. According to the narrow conception that is common in Anglo Saxon countries, science is restricted to those disciplines that investigate nature and aim at explanation and prediction of natural phenomena. A wider conception that can be found in various European countries includes social sciences, the humanities and engineering. On the other hand and related to the first aspect, there is still no general consensus on the specific characteristics of scientific discoveries and scientific knowledge.
Programming the Universe: The First Commandment of Software Engineering for all Varieties of Information Systems
Venue: SBES '16

Since the early days of computers and programs, the process and outcomes of software development has been a minefield plagued with problems and failures, as much as the complexity and complication of software and its development has increased by a thousandfold in half a century. Over the years, a number of theories, laws, best practices, manifestos and methodologies have emerged, with varied degrees of (un)success. Our experience as software engineers of complex and large scale systems shows that those guidelines are bound to previously defined and often narrow scopes. Enough is enough. Nowadays, nearly every company is in the software and services business and everything is or is managed by software. It is about time, then, that the laws that govern our universe ought to be redefined. In this context, we discuss and present a set of universal laws that leads us to propose the first commandment of software engineering for all varieties of information systems.
A real time error measuring device for meso scale machine tools

This paper describes the development of a real time error measuring device for the simultaneous measurement of movement errors in straightness, yaw and roll in a linear machine stage. It was designed specifically for measuring errors in the spatial positioning of meso scale machine tool stages. The arrangement of the optical path and design of the optical elements make it easy install the device on a linear stage. Roll, yaw and horizontal straightness error motions are sensed using the reflection of a laser beam from a plane mirror. A nonlinear measurement model was derived and simulation analysis showed this could be linearized when the measurement angle error was smaller than 0.05deg. The measurement ranges of the proposed system are 30' for th x 20' for th y and 30 mm for the z axis. The measurement precision was verified using a laser interferometer and an electronic level and the accuracy of the angular error and straightness error measurements were found to be in the range of 0.25' and 0.5 mm respectively. The extended measurement uncertainties (95% confidence level) were: 0.46' for th x error motion; 0.46' for th y error motion; and 0.616 mm for straightness.
EZH2 and BCL6 Cooperate to Assemble CBX8 BCOR Complex to Repress Bivalent Promoters, Mediate Germinal Center Formation and Lymphomagenesis.
Venue: Cancer cell

The EZH2 histone methyltransferase mediates the humoral immune response and drives lymphomagenesis through formation of bivalent chromatin domains at critical germinal center (GC) B cell promoters. Herein we show that the actions of EZH2 in driving GC formation and lymphoma precursor lesions require site specific binding by the BCL6 transcriptional repressor and the presence of a non canonical PRC1 BCOR CBX8 complex. The chromodomain protein CBX8 is induced in GC B cells, binds to H3K27me3 at bivalent promoters, and is required for stable association of the complex and the resulting histone modifications. Moreover, oncogenic BCL6 and EZH2 cooperate to accelerate diffuse large B cell lymphoma (DLBCL) development and combinatorial targeting of these repressors results in enhanced anti lymphoma activity in DLBCLs.
