The association between dietary inflammatory index and risk of central obesity in adults: An updated systematic review and meta analysis.
Venue: International journal for vitamin and nutrition research. Internationale Zeitschrift fur Vitamin und Ernahrungsforschung. Journal international de vitaminologie et de nutrition
Year: 2020

Central obesity, as a pivotal component of metabolic syndrome is associated with numerous co morbidities. Dietary factors influence central obesity by increased inflammatory status. However, recent studies didn't evaluate the association between central obesity and dietary inflammation index (DII(r) that give score to dietary factors according to their inflammatory potential. In the current systematic review and meta analysis, we summarized the studies that investigated the association between DII(r) with central obesity indices in the general populations.  In a systematic search from PubMed, SCOPUS, Web of Sciences and Cochrane electronic databases, we collected relevant studies written in English and published until 30 October 2019. The population of included studies were apparently healthy subjects or individuals with obesity or obesity related diseases. Observational studies that evaluated the association between DII(r) and indices of central obesity including WC or WHR were included.  Totally thirty two studies were included; thirty studies were cross sectional and two were cohort studies with 103071 participants. Meta analysis of observational studies showed that higher DII(r) scores were associated with 1.81 cm increase in WC (Pooled weighted mean difference (WMD) 1.813; CI: 0.785 2.841; p 0.001) Also, a non significant increase in the odds of having higher WC (OR 1.162; CI: 0.95 1.43; p 0.154) in the highest DII category was also observed. In subgroup analysis, the continent, dietary assessment tool and gender were the heterogeneity sources.  The findings proposed that adherence to diets with high DII(r) scores was associated with increased WC. Further studies with interventional designs are necessary to elucidate the causality inference between DII(r) and central obesity indices.
Novel quantum phenomena induced by strong magnetic fields in heavy ion collisions
Year: 2016

AbstractThe relativistic heavy ion collisions create both hot quark gluon matter and strong magnetic fields, and provide an arena to study the interplay between quantum chromodynamics and quantum electrodynamics. In recent years, it has been shown that such an interplay can generate a number of interesting quantum phenomena in hadronic and quark gluon matter. In this short review, we first discuss some properties of the magnetic fields in heavy ion collisions and then give an overview of the magnetic field induced novel quantum effects. In particular, we focus on the magnetic effect on the heavy flavor mesons, the heavy quark transports, and the phenomena closely related to chiral anomaly.
IoT enabled directed acyclic graph in spark cluster
Venue: J. Cloud Comput.
Year: 2020

Real time data streaming fetches live sensory segments of the dataset in the heterogeneous distributed computing environment. This process assembles data chunks at a rapid encapsulation rate through a streaming technique that bundles sensor segments into multiple micro batches and extracts into a repository, respectively. Recently, the acquisition process is enhanced with an additional feature of exchanging IoT devices' dataset comprised of two components: (i) sensory data and (ii) metadata. The body of sensory data includes record information, and the metadata part consists of logs, heterogeneous events, and routing path tables to transmit micro batch streams into the repository. Real time acquisition procedure uses the Directed Acyclic Graph (DAG) to extract live query outcomes from in place micro batches through MapReduce stages and returns a result set. However, few bottlenecks affect the performance during the execution process, such as (i) homogeneous micro batches formation only, (ii) complexity of dataset diversification, (iii) heterogeneous data tuples processing, and (iv) linear DAG workflow only. As a result, it produces huge processing latency and the additional cost of extracting event enabled IoT datasets. Thus, the Spark cluster that processes Resilient Distributed Dataset (RDD) in a fast pace using Random access memory (RAM) defies expected robustness in processing IoT streams in the distributed computing environment. This paper presents an IoT enabled Directed Acyclic Graph (I DAG) technique that labels micro batches at the stage of building a stream event and arranges stream elements with event labels. In the next step, heterogeneous stream events are processed through the I DAG workflow, which has non linear DAG operation for extracting queries' results in a Spark cluster. The performance evaluation shows that I DAG resolves homogeneous IoT enabled stream event issues and provides an effective stream event heterogeneous solution for IoT enabled datasets in spark clusters.
Multichannel Security Protocols
Venue: IEEE Pervasive Computing
Year: 2007

Multichannel security protocols transmit messages over multiple communication channels, taking into account each channel's security properties. Our first intentional use of these protocols goes back to a 1999 article that proposed physical contact for imprinting as opposed to the wireless channel used in subsequent operations. Only later did we understand three key points. First, explicit use of multiple channels in the same protocol can offer significant advantages for both security and usability. Second, explicitly stating the properties of the channel on which each protocol message is transmitted is useful for understanding one's own protocol in greater depth and therefore for addressing subtle vulnerabilities early on. Third, multichannel protocols existed long before we recognized them as such think of the courier handcuffed to the briefcase carrying the code book that will later protect postal or telegraphic traffic. The paper presents a security protocol that exploit additional transmissions over lower capacity channels, typically found in ubicomp environments, that offer a different combination of security properties.
Assembling International Development Through Capture: The Management and Accounting Control of Non Governmental Organizations (NGOs)
Year: 2013

This study explores the management and accounting requirements that international development Non governmental organizations (NGOs) adopt to be eligible for grants. More specifically, based on interviews conducted with state funding agencies, international NGOs, and Guatemalan and El Salvadorian NGOs and analysis of their reports to funding agencies, the article describes funding requirements and explores how they are implicated in the transformation of the social justice movement assemblage: components of which are technically and administratively rearticulated as components of the international development assemblage. This transformation is explained through Deleuze and Guattari's (1987) 'state form' a mode of governing whereby "state apparatus of capture" hierarchically stratifies an assemblage by enrolling components of the social movement (territorialisation) arranging them through homogenizing administrative categories (coding) and enabling an emergent functional totality (overcoding) that has had the effect of, what some interviewees referred to as, 'disarticulating the social movement. There is however contestation, as strategies are employed by NGOs to leak financial and political resources to organizations that would otherwise not be eligible for funding. This study seeks to extend the work that has critically examined the role of NGOs in the social justice movement and the role of state modes of governance in this process. It emphasizes the impact of management and accounting controls on the constitution and transformation of assemblages and NGOs' advocacy and mission.
Automatic Multiple Choice Question Generation From Text: A Survey
Venue: IEEE Transactions on Learning Technologies
Year: 2020

Automatic multiple choice question (MCQ) generation from a text is a popular research area. MCQs are widely accepted for large scale assessment in various domains and applications. However, manual generation of MCQs is expensive and time consuming. Therefore, researchers have been attracted toward automatic MCQ generation since the late 90's. Since then, many systems have been developed for MCQ generation. We perform a systematic review of those systems. This paper presents our findings on the review. We outline a generic workflow for an automatic MCQ generation system. The workflow consists of six phases. For each of these phases, we find and discuss the list of techniques adopted in the literature. We also study the evaluation techniques for assessing the quality of the system generated MCQs. Finally, we identify the areas where the current research focus should be directed toward enriching the literature.
A composite structural high temperature resistant adhesive based on in situ grown mullite whiskers
Year: 2020

The effect of whisker growing catalyzed by different amounts of AlF3 on the various properties of an epoxy/silicone resin based high temperature resistant adhesive was comprehensively investigated. Although the addition of AlF3 promoted the oxidation reactions, accelerated the premature formation of mullite whiskers, increased the production of SiC ceramic, and reduced the thermal expansion of bonding layer, the excessive use of AlF3 induced many more large holes in the bonding layer, caused the structural heterogeneity, and made mullite whiskers overgrow, thus finally led to the weaker mechanical properties of adhesives. The best dosage of AlF3 in this work was 3 (mass fraction) a uniform composite structure that whisker weaved adhesive frame kept steady from 1100 degC to 1500 degC, and an impressive bonding strength of 63 MPa was achieved at 1100 degC, 80 higher than that of the blank sample. Under the synergistic effect of whisker repair, whisker bridging, whisker drawing and crack deflection, a multi stage fracture phenomenon happened during the shear test, and the fracture displacement of 1100 degC calcined adhesive with 3 AlF3 increased by 61 compared with that of the black sample.

UNSUPERVISED MORPHOLOGICAL SEGMENTATION FOR STATISTICAL MACHINE TRANSLATION
Year: 2010

Statistical Machine Translation (SMT) techniques often assume the word is the basic unit of analysis. These techniques work well when producing output in languages like English, which has simple morphology and hence few word forms, but tend to perform poorly on languages like Finnish with very complex morphological systems with a large vocabulary. This thesis examines various methods of augmenting SMT models to use morphological information to improve the quality of translation into morphologically rich languages, comparing them on an English Finnish translation task. We investigate the use of the three main methods to integrate morphological awareness into SMT systems: factored models, segmented translation, and morphology generation models. We incorporate previously proposed unsupervised morphological segmentation methods into the translation model and combine this segmentation based system with a Conditional Random Field morphology prediction model. We find the morphology aware models yield significantly more fluent translation output compared to a baseline word based model.

Year: 2009

Fundamentos y objetivo La hipertrigliceridemia es un factor de riesgo cardiovascular independiente, que forma parte del sindrome metabolico y del sindrome dismetabolico posprandial. La determinacion de los trigliceridos (TG) en sangre capilar sin duda facilitaria el diagnostico de esas alteraciones. El objetivo del presente estudio fue analizar la concordancia entre los valores de TG medidos en sangre total y capilar (Accutrend(r) GCT Roche Diagnostics) Pacientes y metodo Se incluyo a 50 voluntarios sin enfermedad cardiovascular, en quienes se determinaron simultaneamente los TG en sangre capilar y por venopuncion. Resultados Se observaron valores mas altos en la determinacion capilar (116,5mg/dl frente a 86,0mg/dl; p<0,001) y una correlacion excelente entre ambas determinaciones (r=0,95; p<0,001) Conclusiones En esta muestra de pacientes consecutivos no seleccionados demostramos que la medicion capilar de TG se correlaciona excelentemente con la medicion en sangre y que existen diferencias relevantes en las determinaciones entre ambos sexos. Se proponen ecuaciones de regresion para la estimacion de los valores de TG en sangre a partir de una determinacion capilar: varones: TG capilar X 0,837; mujeres: TG capilar X 0,698.
A Pilot Mind Body Resiliency Intervention Targeting Fear of Recurrence among Cancer Survivors.
Venue: Journal of psychosomatic research
Year: 2020

Interventions for fear of recurrence (FOR) of cancer have nominal effects, perhaps due to limited integration of empirically supported skills. This pilot trial tested the acceptability and feasibility of a multimodal, mind body resiliency intervention targeting FOR among survivors of various cancers.  Early stage cancer survivors 330 months post treatment were recruited to participate in an eight session in person mind body resiliency group intervention that taught relaxation skills, cognitive behavioral techniques, healthy lifestyle behaviors, mindfulness meditation, and positive psychology skills all targeted for FOR. Primary outcomes were feasibility (enrollment rate, session attendance, survey completion, skills practice) and acceptability (enjoyableness, convenience, helpfulness, relevance) Patient reported outcomes (FOR, uncertainty intolerance, cancer related uncertainty, perceived stress, resiliency, positive affect, and coping skills) were collected at baseline, post intervention, +1 month, and +3 months. Exit interviews assessed survivors' reported benefits.  Participants (N 4 groups, 23 survivors, enrollment response rate 58% included survivors of seven common cancer types who were on average 12 months post treatment. Attendance was high (M 6.1 sessions) and 96% of survivors completed all surveys. Sustained increases in relaxation skills practice 3+ days/week were reported (baseline 16% post intervention 76% +3 months 71% Most sessions (87% were rated as highly or very highly acceptable. Moderate to large (d 0.87) improvements in FOR severity were observed post intervention (p .01) and across assessments (p .01) with similar changes observed in other patient reported outcomes. Exit interviews revealed behavioral, cognitive, emotional, and existential benefits.  The targeted mind body resiliency intervention shows promising acceptability, feasibility, and favorable changes in FOR and coping skills practice. Further adaptation and testing in a randomized trial are warranted.
Distance Learning and the Control Theory Metaphor
Year: 2015

This monogram offers an empirical discussion of a common issue appearing in the design of eLearning courses nowadays and the even more commonly found misperception of many faculty about delivering such courses. These issues are viewed from the perspective of an engineer designing a mechanical control system, the design of which can affect the mechanical output or behaviour of the system resulting in different outputs based on the existence and proper use of its various components. Courses designed for online delivery, just like mechanical systems, require input, controllers and regulators, and a sought after output. The components of online courses form a dynamical eLearning system in which, similarly to its mechanical counterparts, the mere presence of the components themselves cannot result in an optimally controlled system without the presence of necessary and appropriate controllers. This critical review of the topic identifies the current realities and drawbacks and offers an innovative view in the context of distance learning systems and their impact.
Restaurant food waste management using microwave plasma gasification technology
Year: 2018

The novelty of this research is that it investigates an on site solution for the treatment of restaurant waste using a microwave generated plasma for pyrolysis and gasification. The developed system has been used to treat waste from a city centre fast food restaurant. The system was designed with the aim of reducing the amount of waste being sent to landfill by approximately 94% The waste is mostly food based but also includes paper waste such as napkins. It was separated into three categories: mixed food, paper and fries. Samples of the mixed food and paper waste were analysed for chemical composition and calorific value. A 2.45GHz magnetron was used to supply 1kW of microwave power to a plasma cavity that had an argon flow rate of 1.5 litre per minute. The design of the microwave plasma cavity was performed using the simulation software, COMSOL. The cavity consists of a tapered waveguide section that is shorted at one end to produce a stationary wave with a large electric field at the gas nozzle. The field is strong enough to produce a self striking argon plasma when the power is applied. Nitrogen was used to keep the plasma cavity clear of smoke, vapours and other hot gas. The best nitrogen flow rates were found to be around 2 litres/minute, although 5 litres/minute was used in the test to avoid the CO sensor saturating. The combination of the argon and nitrogen was used to purge the gasifier of oxygen. The pressure inside the gasifier was held at 200mbar during the experiments. The resulting plasma jet was used to produce syngas from the waste samples inside a thermally insulated, steel walled reactor. Temperature profiles were recorded to find the best gas flow rates. 10g samples of the three waste categories were tested in triplicate and the results are presented. Syngas production was recorded using a Quintox gas analyser that measured CO, CO2 and O2. The data was captured every 10s during testing using a PC running a custom built LabVIEW program. This program was also used to set the microwave output power and record the reflected power and temperatures using National Instruments cDAQ modules with analogue to digital converters. The CO and H2 in syngas can be used as a fuel to offset the cost of running the plasma jet. The results reveal that it is possible to generate the syngas using waste food materials. This study has included an investigation of some of the parameters, including power and flow rates of argon and nitrogen, on the plasma created. Others effects were taken into consideration throughout the research such as the study of the sample moisture levels and the final reduction of mass after the experiment. The ashes produced by the tests were investigated using SEM/EDX analysis. These results are also presented and analysed.
Anaerobic co digestion of mixed sewage sludge and fruits and vegetable wholesale market waste: Composition and seasonality effect
Venue: Journal of Water Process Engineering
Year: 2019

Fruit and vegetable wastes (FVW) generated in a wholesale market, and mixed sewage sludge (MSS) from a municipal wastewater treatment plant (WWTP) are heterogeneous residues that may suffer important seasonal changes. We study the influence of those possible changes on the co digestion of both residues. All the experiments were conducted under mesophilic conditions for samples corresponding to four different seasons, with a total feeding volume of 0.250 L d 1 and a constant hydraulic retention time (20 d) with six different FVW MSS percentage volumetric relations (PVR) 0:100, 20:80, 40:60, 60:40, 80:20 and 100:0. The biogas and methane production rates increased with the volumetric percentage of FVW in the feed. For instance, as the PVR changed from 0:100 to 100:0 the increase of the biogas production was 10 fold in the summer season and 4 fold for the winter season. Regarding the biogas and methane specific production rates slight improvements can be observed with respect to the use of MSS alone, but remains almost constant for the PVRs between 40:60 and 100:0. This indicates that the main reason for the biogas production improvement is the larger concentration of VS in the FVW. The digester remained under stable conditions, even for the largest organic loading rate (OLR) studied (5.8 g L 1 d 1) regardless the variations between seasons. Therefore, management of both residues together at the facilities available at the WWTP would be a very good option.
