Non intrusive Coupling: Recent Advances and Scalable Nonlinear Domain Decomposition

This paper provides a detailed review of the global/local non intrusive coupling algorithm. Such method allows to alter a global finite element model, without actually modifying its corresponding numerical operator. We also look into improvements of the initial algorithm (Quasi Newton and dynamic relaxation) and provide comparisons based on several relevant test cases. Innovative examples and advanced applications of the non intrusive coupling algorithm are provided, granting a handy framework for both researchers and engineers willing to make use of such process. Finally, a novel nonlinear domain decomposition method is derived from the global/local non intrusive coupling strategy, without the need to use a parallel code or software. Such method being intended to large scale analysis, we show its scalability. Jointly, an efficient high level Message Passing Interface coupling framework is also proposed, granting an universal and flexible way for easy software coupling. A sample code is also given.

Energy Resolution of Ce GAGG and Pr LuAG Scintillators coupled to 3 mm x 3 mm Silicon

Silicon Photomultipliers (SiPM) have shown great promise as a suitable replacement for conventional vacuum based Photomultiplier Tubes (PMT) Progress in recent years has been vast with SiPM sensors pushing the boundaries in energy and timing resolution as well as photon detection efficiency and active surface area. In this study we report the energy resolution and linearity of two novel scintillator crystals, Cerium doped Gd3Al2Ga3O12 (Ce:GAGG) and Praseodymium doped Lu3Al5O12 (Pr:LuAG) readout by three different types of 3 x 3mm silicon photomultiplier sensors produced by SensL (MicroFM, MicroFB, MicroFC) Such a scintillator SiPM architecture has applications in pre clinical and clinical medical imaging modalities such as Positron Emission Tomography (PET) Non P (M series) P on N (B series) and a low noise P on N (C series) versions of the SiPM sensor platform have been coupled to the crystals and the response characterized over a range of gamma energies and detector bias values. A saturation corrected energy resolution of 11.7% was achieved for a MicroFM device coupled to a 3x3x30 mm Ce:GAGG crystal at 20*C. An energy resolution of 16.1% was obtained for a MicroFB device optically coupled to to a 3x3x30mm Pr:LuAG crystal at 20*C.
A Reliability Augmented Particle Filter for Magnetic Fingerprinting Based Indoor Localization on Smartphone
Venue: IEEE Transactions on Mobile Computing

Using magnetic field data as fingerprints for smartphone indoor positioning has become popular in recent years. Particle filter is often used to improve accuracy. However, most of existing particle filter based approaches either are heavily affected by motion estimation errors, which result in unreliable systems, or impose strong restrictions on smartphone such as fixed phone orientation, which are not practical for real life use. In this paper, we present a novel indoor positioning system for smartphones, which is built on our proposed reliability augmented particle filter. We create several innovations on the motion model, the measurement model, and the resampling model to enhance the basic particle filter. To minimize errors in motion estimation and improve the robustness of the basic particle filter, we propose a dynamic step length estimation algorithm and a heuristic particle resampling algorithm. We use a hybrid measurement model, combining a new magnetic fingerprinting model and the existing magnitude fingerprinting model, to improve system performance, and importantly avoid calibrating magnetometers for different smartphones. In addition, we propose an adaptive sampling algorithm to reduce computation overhead, which in turn improves overall usability tremendously. Finally, we also analyze the "Kidnapped Robot Problem" and present a practical solution. We conduct comprehensive experimental studies, and the results show that our system achieves an accuracy of 1~2 m on average in a large building.

The genus Hypericum (Hypericaceae) has attracted remarkable scientific interest as its members accumulate significant amounts of various bioactive compounds. In the current study, we investigated accumulation of several bioactive compounds in various parts of Hypericum hircinum L. subsp. majus (Ainton) N. Robson, H. pallens Banks et Sol. H. russeggeri (Fenzl) R. Keller and H. lanuginosum Lam. The plant materials were harvested at flowering, dissected into different tissues and subsequently subjected to high performance liquid chromatography (HPLC) analyses. Accumulation level of the investigated compounds varied greatly depending on species and plant parts. Among different plant tissues, flowers were found to be superior to leaves with respect to accumulation of the chemicals tested except for neochlorogenic, caffeic and 2,4 dihydroxybenzoic acids which were accumulated mainly in leaves. H. hircinum did not produce quercitrin or avicularin, H. lanuginosum did not accumulate hyperforins and caffeic acid, rutin was detected only in H. pallens. For the first time, chemical profiles of these Turkish species of Hypericum were reported and the results are discussed from a phytochemical point of view. The present data could be helpful in selecting the future targets for phytochemical and biological studies on Hypericum genus as well as enriching our current knowledge about Hypericum chemistry.
Design of an Axial Flux Permanent Magnet Synchronous Machine Using Analytical Method and Evolutionary Optimization
Venue: IEEE Transactions on Energy Conversion

The design optimization of an axial flux permanent magnet synchronous machine with a coreless stator and double external rotor is accomplished by using evolutionary optimization with a genetic algorithm and an analytical evaluation of objective functions. On the basis of eight variable geometry parameters, five objective functions are optimized in order to determine the maximum volume torque density and weight torque density, the minimum volume and weight of permanent magnets per Newton meter, and the minimum machine price per Newton meter. Based on the geometric parameters for minimum machine price per Newton meter, a prototype is built for the rated torque. Optimized and analytically evaluated machine characteristics are validated with a finite element method (FEM) and the measurements of a prototype. Evolutionary optimization with the analytical evaluation of objective functions significantly shortens the computational time required for design optimization in comparison with the FEM.
Patterns in the Chaos A Study of Performance Variation and Predictability in Public IaaS Clouds
Venue: ACM Trans. Internet Techn.

Benchmarking the performance of public cloud providers is a common research topic. Previous work has already extensively evaluated the performance of different cloud platforms for different use cases, and under different constraints and experiment setups. In this article, we present a principled, large scale literature review to collect and codify existing research regarding the predictability of performance in public Infrastructure as a Service (IaaS) clouds. We formulate 15 hypotheses relating to the nature of performance variations in IaaS systems, to the factors of influence of performance variations, and how to compare different instance types. In a second step, we conduct extensive real life experimentation on four cloud providers to empirically validate those hypotheses. We show that there are substantial differences between providers. Hardware heterogeneity is today less prevalent than reported in earlier research, while multitenancy has a dramatic impact on performance and predictability, but only for some cloud providers. We were unable to discover a clear impact of the time of the day or the day of the week on cloud performance.
Anti sway tracking control of tower cranes with delayed uncertainty using a robust adaptive fuzzy control
Venue: Fuzzy Sets Syst.

Tower cranes are very complex mechanical systems and have been the subject of research investigations to reduce the swaying of the payload for several decades. Inherently, the dynamical model of the tower cranes is highly nonlinear and classified as underactuated. Also, the actuators are far from the payload which makes the system non colocated. It is proposed here to use an H based adaptive fuzzy control technique to control the swaying motion of a tower crane. The advantage of employing an adaptive fuzzy system is the use of linear analytical results instead of estimating the dynamics of the tower crane with an online update law. The proposed robust control law for payload positioning is based on a variable structure (VS) adaptive fuzzy control scheme. The adaptive fuzzy control technique fuses a VS scheme and it is derived based on a Lyapunov criterion and the Riccati inequality. The control design overcomes modeling inaccuracies, such as drag and friction losses, effect of time delays from backlash, as well as parameter uncertainties and compensate for the effect of the external disturbances on tracking error such that all the states of the system are uniformly ultimately bounded (UUB) Therefore, the H tracking performance can be achieved such that the payload swing is reduced to as small as possible when the payload is moved from point to point. Simulations show that the proposed control scheme is effective in reducing payload swing in the presence of uncertainties, time delays, and external disturbances.
Caregiving Practice Patterns of Asian, Hispanic, and Non Hispanic White American Family Caregivers of Older Adults Across Generations
Venue: Journal of cross cultural gerontology

This study is a cross sectional investigation of caregiving practice patterns among Asian, Hispanic and non Hispanic White American family caregivers of older adults across three immigrant generations. The 2009 California Health Interview Survey (CHIS) dataset was used, and 591 Asian, 989 Hispanic and 6537 non Hispanic White American caregivers of older adults were selected. First, descriptive analyses of caregivers' characteristics, caregiving situations and practice patterns were examined by racial/ethnic groups and immigrant generations. Practice patterns measured were respite care use, hours and length of caregiving. Three hypotheses on caregiving patterns based on assimilation theory were tested and analyzed using logistic regression and generalized linear models by racial/ethnic groups and generations. Caregiving patterns of non Hispanic White caregivers supported all three hypotheses regarding respite care use, caregiving hours and caregiving duration, showing less caregiving involvement in later generations. However, Asian and Hispanic counterparts showed mixed results. Third generation Asian and Hispanic caregivers used respite care the least and spent the most caregiving hours per week and had the longest caregiving duration compared to earlier generations. These caregiving patterns revealed underlying cultural values related to filial responsibility, even among later generations of caregivers of color. Findings suggest the importance of considering the cultural values of each racial/ethnic group regardless of generation when working with racially and ethnically diverse populations of family caregivers of older adults.
Analyzing older users' home telehealth services acceptance behavior applying an Extended UTAUT model
Venue: Int. J. Medical Informatics

Although telehealth offers an improved approach to providing healthcare services, its adoption by end users remains slow. With an older population as the main target, these traditionally conservative users pose a big challenge to the successful implementation of innovative telehealth services.  The objective of this study was to develop and empirically test a model for predicting the factors affecting older users' acceptance of Home Telehealth Services (HTS) METHODS A survey instrument was administered to 400 participants aged 50 years and above from both rural and urban environments in Slovenia. Structural equation modeling was applied to analyze the causal effect of seven hypothesized predicting factors. HTS were introduced as a bundle of functionalities, representing future services that currently do not exist. This enabled users' perceptions to be measured on the conceptual level, rather than attitudes to a specific technical solution.  Six relevant predictors were confirmed in older users' HTS acceptance behavior, with Performance Expectancy (r=0.30) Effort Expectancy (r=0.49) Facilitating Conditions (r=0.12) and Perceived Security (r=0.16) having a direct impact on behavioral intention to use HTS. In addition, Computer Anxiety is positioned as an antecedent of Effort Expectancy with a strong negative influence (r= 0.61) and Doctor's Opinion influence showed a strong impact on Performance Expectancy (r=0.31) The results also indicate Social Influence as an irrelevant predictor of acceptance behavior. The model of six predictors yielded 77% of the total variance explained in the final measured Behavioral Intention to Use HTS by older adults.  The level at which HTS are perceived as easy to use and manage is the leading acceptance predictor in older users' HTS acceptance. Together with Perceived Usefulness and Perceived Security, these three factors represent the key influence on older people's HTS acceptance behavior. When promoting HTS, interventions should focus to portray it as secure. Marketing interventions should focus also on promoting HTS among health professionals, using them as social agents to frame the services as useful and beneficial. The important role of computer anxiety may result in a need to use different equipment such as a tablet computer to access HTS. Finally, this paper introduces important methodological guidelines for measuring perceptions on a conceptual level of future services that currently do not exist.
Toward an Understanding of Government Cloud Acceptance A Quantitative Study of G Cloud Acceptance by Saudi Government Agencies using Extended UTAUT
Venue: CLOSER

With todayas rapid advances in Information and Communication Technologies (ICT) an increasing number of governments worldwide are seeking solutions to enhance their IT infrastructures and services, and reshape their e government systems to meet public needs of providing easily accessible, cost effective, high quality, and reliable e services. In recent years, government cloud (G Cloud) has emerged as a new and innovative computing paradigm with a promising opportunity for many governments to rationalize the way they manage their services and resources. Government cloudas potential benefits has been recognized by many governments around the world. This paper will study the acceptance of cloud computing technologies and services in Saudi government agencies by investigating the significant and influential factors that affect the behavioral intentions to use G Cloud. Moreover, in light of the rising concerns over trust issues in cloud computing which have been reported to be one of the major barriers to the adoption of the cloud, the study proposes an extended Unified Theory of Acceptance and Use of Technology (UTAUT) model by incorporating trust as a key factor in the acceptance of G Cloud.
Aggregate and Idiosyncratic Political Risk: Measurement and Effects

We propose a new measure of political risk faced by individual US firms based on textual analysis of earnings conference call transcripts: the share of the conversation between management and analysts that is devoted to political topics. Our measure correlates significantly with firm level stock return volatility, even after controlling for firm and time fixed effects. We find that increases in idiosyncratic political risk are associated with decreases in investment and hiring, and that the dispersion of idiosyncratic political risk tends to increase significantly in times of high aggregate political risk. About two thirds of the variation in political risk is idiosyncratic in the sense that it is neither captured by firm or time fixed effects, nor by heterogeneous exposure of individual firms to aggregate political risk. Further decomposing our measure by political topic, we find that discussion of risk associated with corporate regulation and health care is associated with the largest decreases in investment. We also find that firms actively manage political risk through lobbying: firms that devote more time to discussing the risk associated with a given political topic tend to increase lobbying expenses on that topic that quarter. These effects are most pronounced for large firms and firms headquartered in states that are associated with higher levels of political corruption.
Biological signaling by small inorganic molecules.
Venue: Coordination chemistry reviews

Small redox active molecules such as reactive nitrogen and oxygen species and hydrogen sulfide have emerged as important biological mediators that are involved in various physiological and pathophysiological processes. Advancement in understanding of cellular mechanisms that tightly regulate both generation and reactivity of these molecules is central to improved management of various disease states including cancer and cardiovascular dysfunction. Imbalance in the production of redox active molecules can lead to damage of critical cellular components such as cell membranes, proteins and DNA and thus may trigger the onset of disease. These small inorganic molecules react independently as well as in a concerted manner to mediate physiological responses. This review provides a general overview of the redox biology of these key molecules, their diverse chemistry relevant to physiological processes and their interrelated nature in cellular signaling.
The Most Common Herbs to Cure the Most Common Oral Disease: Stomatitis Recurrent Aphthous Ulcer (RAU)
Venue: Iranian Red Crescent medical journal

Recurrent aphthous ulcer (RAU) is an oral disease and the most common oral lesion, with 2% to 66% of the world's population infected annually. Its prevalence is about 25% in Tehran and 27.6% in Mashhad. The etiology of RAU is multifactorial. Aphthous risk factors include: immunological factors, psychological factors, stress, trauma, sensitivity, family history, blood disorders, malnutrition, and use of certain medications, It should be noted that the best treatment for RAU is the topical application of drugs. The use of topical treatments is recommended not only because the drug can directly impact the source of the disease, but also systemic side effects of the drug are reduced. Treatment of RAU has been considered in Iranian traditional medicine (ITM) and is covered in therapeutic books. The use of herbs in RAU has a centuries old history; accordingly, extensive research should be conducted for this treatment of the disease.  Iranian medical sources were reviewed and effective plants used in the traditional treatment of RAU were found and compared with new findings. Finally, we have created a table listing the plants that are part of the therapeutic protocol for RAU.  Based on this article we can explain some of traditional pharmacological effects of plants and how these plants can be a source for a cure.  The plants listed can be used as a prediction of RAU management. Of course, there are is no evidence for curing RAU by some of these plants in allopathic medicine, and the further investigations in this area could lead to the discovery of a new drug
