Learning Hierarchical Review Graph Representation for Recommendation
Venue: ArXiv
Year: 2020

The user review data have been demonstrated to be effective in solving different recommendation problems. Previous review based recommendation methods usually employ sophisticated compositional models such as Recurrent Neural Networks (RNN) and Convolutional Neural Networks (CNN) to learn semantic representations from the review data for recommendation. However, these methods mainly capture the local and consecutive dependency between neighbouring words in a word window. Therefore, they may not be effective in capturing the long term, non consecutive, and global dependency between words coherently. In this paper, we propose a novel review based recommendation model, named Review Graph Neural Network (RGNN) Specifically, RGNN builds a specific review graph for each individual user/item, where nodes represent the review words and edges describe the connection types between words. A type aware graph attention mechanism is developed to learn semantic embeddings of words. Moreover, a personalized graph pooling operator is proposed to learn hierarchical representations of the review graph to form the semantic representation for each user/item. We compared RGNN with state of the art review based recommendation approaches on real datasets. The experimental results indicate that RGNN usually outperforms baseline methods in terms of mean square error.

A cross cultural comparison of Ecuadorian and United States face, facework, and conflict styles during interpersonal conflict: An application of face negotiation theory
Year: 2016

This study applied and extended face negotiation theory in a cross cultural comparison of face, facework, and conflict management styles between Ecuador and the United States (US) Participants included students from the United States and Ecuador. Participants completed a questionnaire that measured face, facework, and conflict style preference in one of two recalled conflict situations that varied in relational closeness (i.e. intimate, nonintimate) Results reveal that Ecuadorian and U.S. students did not differ in their self face, other face, and mutual face concerns. Ecuadorian and U.S. students differed significantly in their preference for facework and conflict style preferences across the two conflict situations, however.
Modelling Environment Changes for Pricing Weather Derivatives
Year: 2017

This paper focuses on modelling environment changes in a way that allows to price weather derivatives in a flexible and efficient way. Applications and importance of climate and weather contracts extends beyond financial markets and hedging as they can be used as complementary tools for risk assessment. In addition, option based approach toward resource management can offer very special insights on rare events and allow to reuse derivative pricing methods to improve natural resources management. To demonstrate this general concept, we use Monte Carlo and stochastic modelling of temperatures to evaluate weather options. Research results are accompanied by R and Python code.
MicroRNA 92a promotes vascular smooth muscle cell proliferation and migration through the ROCK/MLCK signalling pathway
Venue: Journal of cellular and molecular medicine
Year: 2019

To identify the interaction between known regulators of atherosclerosis, microRNA 92a (miR 92a) Rho associated coiled coil forming kinase (ROCK) and myosin light chain kinase (MLCK) we examined their expressions during proliferation and migration of platelet derived growth factor BB (PDGF BB) regulated vascular smooth muscle cells (VSMCs) both in vivo and in vitro. During the formation of atherosclerosis plaque in mice, a parallel increase in expression levels of MLCK and miR 92a was observed while miR 92a expression was reduced in ML 7 (an inhibitor of MLCK) treated mice and in MLCK deficient VSMCs. In vitro results indicated that both MLCK and miR 92a shared the same signalling pathway. Transfection of miR 92a mimic partially restored the effect of MLCK's deficiency and antagonized the effect of Y27632 (an inhibitor of ROCK) on the down regulation of VSMCs activities. ML 7 increased the expression of Kruppel like factor 4 (KLF4, a target of miR 92a) and siRNA KLF4 increased VSMCs' activity level. Consistently, inhibition of either MLCK or ROCK enhanced the KLF4 expression. Moreover, we observed that ROCK/MLCK up regulated miR 92a expression in VSMCs through signal transducer and activator of transcription 3 (STAT3) activation. In conclusion, the activation of ROCK/STAT3 and/or MLCK/STAT3 may up regulate miR 92a expression, which subsequently inhibits KLF4 expression and promotes PDGF BB mediated proliferation and migration of VSMCs. This new downstream node in the ROCK/MLCK signalling pathway may offer a potential intervention target for treatment of atherosclerosis.
Fairness Oriented User Scheduling for Bursty Downlink Transmission Using Multi Agent Reinforcement Learning
Year: 2020

In this work, we develop practical user scheduling algorithms for downlink bursty traffic with emphasis on user fairness. In contrast to the conventional scheduling algorithms that either equally divides the transmission time slots among users or maximizing some ratios without physcial meanings, we propose to use the 5% tile user data rate (5TUDR) as the metric to evaluate user fairness. Since it is difficult to directly optimize 5TUDR, we first cast the problem into the stochastic game framework and subsequently propose a Multi Agent Reinforcement Learning (MARL) based algorithm to perform distributed optimization on the resource block group (RBG) allocation. Furthermore, each MARL agent is designed to take information measured by network counters from multiple network layers (e.g. Channel Quality Indicator, Buffer size) as the input states while the RBG allocation as action with a proposed reward function designed to maximize 5TUDR. Extensive simulation is performed to show that the proposed MARL based scheduler can achieve fair scheduling while maintaining good average network throughput as compared to conventional schedulers.
Assessing abortion coverage in nurse practitioner programs in Canada: a national survey of program directors.
Venue: Contraception
Year: 2016

Although nurse practitioners (NPs) play a critical role in the delivery of reproductive health services in Canada, there is a paucity of published information regarding the reproductive health education provided in their training programs. Our study aimed to understand better the didactic and curricular coverage of abortion in Canadian NP programs.  In 2014, we conducted a 3 contact, bilingual (English French) mailed survey to assess the coverage of, time dedicated to and barriers to inclusion of 17 different areas of reproductive health, including abortion. We also asked respondents to speculate on whether or not mifepristone would be incorporated into the curriculum if approved by Health Canada for early abortion. We analyzed our results with descriptive statistics and used inductive techniques to analyze the open ended questions for content and themes.  Sixteen of 23 (70% program directors or their designees returned our survey. In general, abortion related topics received less coverage than contraception, ectopic pregnancy management and miscarriage management. Fifty six percent of respondents reported that their program did not offer information about first trimester abortion procedures and/or post abortion care in the didactic curriculum. Respondents expressed interest in incorporating mifepristone/misoprostol into NP education and training.  Reproductive health issues receive uneven and often inadequate curricular coverage in Canadian NP programs. Identifying avenues to expand education and training on abortion appears warranted. Embarking on curricular reform efforts is especially important given the upcoming introduction of mifepristone into the Canadian health system for early abortion.  Our findings draw attention to the need to integrate abortion related content into NP education and training programs. The approval of Mifegymiso(r) may provide a window of opportunity to engage in curriculum reform efforts across the health professions in Canada.

Brand Recall for Product Placement in Hindi Movies
Year: 2015

In present era, media fragmentation and proliferation has directed advertisers' interest in developing more effective ways to communicate with consumers. So they are moving with the new concept of promotion named product placement. In this paper, researchers try to study the impact of movie genre, product placement type, and viewer gender on audiences' recall of brand placed in movies in order to know which one gets more attention and more attraction for buying behaviour. This study uses experimental design and comprises samples of 137 students enrolled in MBA course, who watch hindi movies. The research was conducted with three hindi movies and respondents' were asked to recall brands placed in these movies after watching video clips. Data has been collected by the use of questionnaire. This research paper has implications for both academicians and practitioners which include the advertising agency people, the media planners, the brand managers, the movie scriptwriters and producers for developing strategies to increase the use of product placement as a tool for brand communications. Findings suggest that product placed in prominent mode has higher brand recall than product placed in subtle mode. Further it reveals that automobile products are highly recognized products among other products placed in selected hindi movies.
Review of snow water equivalent microwave remote sensing
Venue: Science China Earth Sciences
Year: 2016

Accurate quantitative global scale snow water equivalent information is crucial for meteorology, hydrology, water cycle and global change studies, and is of great importance for snow melt runoff forecast, water resources management and flood control. With land surface process model and snow process model, the snow water equivalent can be simulated with certain accuracy, with the forcing data as input. However, the snow water equivalent simulated using the snow process models has large uncertainties spatially and temporally, and it may be far from the needs of practical applications. Thus, the large scale snow water equivalent information is mainly from remote sensing. Beginning with the launch of Nimbus 7 satellite, the research on microwave snow water equivalent remote sensing has developed for more than 30 years, researchers have made progress in many aspects, including the electromagnetic scattering and emission modeling, ground and airborne experiments, and inversion algorithms for future global high resolution snow water equivalent remote sensing program. In this paper, the research and progress in the aspects of electromagnetic scattering/emission modeling over snow covered terrain and snow water equivalent inversion algorithm will be summarized.
Socio and Healthy Human Psychology upon Biophilic Architecture
Year: 2011

The biophilia hypothesis asserts that people have an evolved affinity for other life, and the implementation of biophilic architecture may serve to further acceptance by laypeople of that essentially biological hypothesis. Biophilic structure on the earth is a valued and appreciated part of life, where areas and human carrier green is not only an excellent synthesis of both qualitative and quantitative research that documents the bond between people and plants, it is a synthesis of the life's work and thinking of one of the most important figures in people plant relationships. Psychological health arises from being in a more preferred environment. Therefore, psychological health can be expected to increase with contact with more preferred, i.e. more natural, environments. A collaborative socio ecological advance between health and environmental management sectors is required to ensure that contact with nature is integral to sustainable development strategies for local and total urban communities.
BEING HUMAN AMONG OTHERKINS:IDENTIFYING THE SIMULACRUM IN JRR TOLKIEN'S THE LORD OF THE RINGS
Year: 2020

Many different characters or races in The Lord of the Rings by JRR Tolkien had drawn many interest from critical readers. In this fantasy story of his, Tolkien utilized characters which were magical beings and 'unrealistic' such as elves, dwarves, wizards, hobbits, orcs, and trolls which were often identified as otherkins. On the other hand, he also presented humans who were 'realistic' characters familiar to the readers. This research was conducted in order to identify what is 'real' and what is 'unreal' and at the same time a 'copy' or a 'fake' The research was presented with a descriptive analytical method, and by assimilating the concept of simulacra by Jean Baudrilliard, it was argued that the line of real, unreal, fake, and copy was blurring. Humans were otherkins, and otherkins were humans.
Autonomous Multi Phenomenology Space Domain Sensor Tasking and Adaptive Estimation
Venue: 2018 21st International Conference on Information Fusion (FUSION)
Year: 2018

Space domain awareness using current human in the loop methods is becoming decreasingly viable. This work presents an approach to sensor network management, maneuver detection, and adaptive estimation for tracking many non maneuvering and multiple maneuvering satellites with a space object surveillance and identification (SOSI) network. The proposed method integrates a suboptimal partially observable Markov decision process (POMDP) with an unscented Kalman filter (UKF) to task sensors and maintain viable orbit estimates for all targets. The method also implements autonomous maneuver detection based on the innovations squared metric. Once detected, the network instantiates a multiple model adaptive estimation (MMAE) filter with various possible maneuvers. This study implemented both a static multiple model (SMM) filter and an interacting multiple model (IMM) filter in order to compare the two methods. When comparing the two multiple model filters' responsiveness and accuracy in this framework, it is shown that the IMM marginally outperforms the SMM for a substantial, impulsive maneuver in three different orbital regimes.
p53 reactivation with induction of massive apoptosis 1 (PRIMA 1) inhibits amyloid aggregation of mutant p53 in cancer cells
Venue: The Journal of Biological Chemistry
Year: 2019

p53 mutants can form amyloid like structures that accumulate in cells. p53 reactivation with induction of massive apoptosis 1 (PRIMA 1) and its primary active metabolite, 2 methylene 3 quinuclidinone (MQ) can restore unfolded p53 mutants to a native conformation that induces apoptosis and activates several p53 target genes. However, whether PRIMA 1 can clear p53 aggregates is unclear. In this study, we investigated whether PRIMA 1 can restore aggregated mutant p53 to a native form. We observed that the p53 mutant protein is more sensitive to both PRIMA 1 and MQ aggregation inhibition than WT p53. The results of anti amyloid oligomer antibody assays revealed that PRIMA 1 reverses mutant p53 aggregate accumulation in cancer cells. Size exclusion chromatography of the lysates from mutant p53 containing breast cancer and ovarian cell lines confirmed that PRIMA 1 substantially decreases p53 aggregates. We also show that MDA MB 231 cell lysates can "seed" aggregation of the central core domain of recombinant WT p53, corroborating the prion like behavior of mutant p53. We also noted that this aggregation effect was inhibited by MQ and PRIMA 1. This study provides the first demonstration that PRIMA 1 can rescue amyloid state p53 mutants, a strategy that could be further explored as a cancer treatment.
Towards a genetic definition of cancer associated inflammation: role of the IDO pathway.
Venue: The American journal of pathology
Year: 2010

Chronic inflammation drives the development of many cancers, but a genetic definition of what constitutes 'cancer associated' inflammation has not been determined. Recently, a mouse genetic study revealed a critical role for the immune escape mediator indoleamine 2,3 dioxygenase (IDO) in supporting inflammatory skin carcinogenesis. IDO is generally regarded as being immunosuppressive; however, there was no discernable difference in generalized inflammatory processes in IDO null mice under conditions where tumor development was significantly suppressed, implicating IDO as key to establishing the pathogenic state of 'cancer associated' inflammation. Here we review recent findings and their potential implications to understanding the relationship between immune escape and inflammation in cancer. Briefly, we propose that genetic pathways of immune escape in cancer are synonymous with pathways that define 'cancer associated' inflammation and that these processes may be identical rather than distinct, as generally presumed, in terms of their genetic definition.
Growth in first and second generation immigrant firms in Sweden
Year: 2016

This article contributes to the research exploring the social and economic factors shaping the performance of immigrant run firms. Drawing upon human and social capital theory and assimilation theory, we investigate differences in performance measured as revenue growth in a comparative study of native and immigrant CEOs. Following 50,002 small firms in Sweden over 4 years, we find distinct patterns in both firm size and revenue growth between firms managed by immigrants and by natives. While firms run by second generation immigrants from the Organization for Economic Co operation and Development (OECD) countries exhibit higher growth rates than natives, the reverse is true for second generation immigrants from non OECD countries, suggesting that economic integration in terms of small business growth immigrants in Sweden is characterized by segmented rather than universal assimilation.
Serum matrix metalloproteinase 3 in detecting remitting seronegative symmetrical synovitis with pitting edema syndrome: A case report
Venue: World journal of clinical cases
Year: 2018

We report a case of remitting seronegative symmetrical synovitis with pitting edema (RS3PE) syndrome in a 71 year old woman. She referred to our hospital with finger stiffness, edema of both hands and feet, pain of bilateral shoulder, wrist, metacarpophalangeal, proximal interphalangeal, and ankle joints. Rheumatoid factor was negative, human leukocyte antigen B7 antigen was positive. Moreover, matrix metalloproteinase 3 (MMP 3) was high. She was diagnosed with RS3PE syndrome, and treatment with prednisolone (15 mg/d) was started. One week after prednisolone treatment initiation, CRP decreased to negative, and joint pain was almost completely resolved. However, hand stiffness persisted, and MMP 3 level was still high. Thus, prednisolone dose was increased to 20 mg/d, and the stiffness resolved. Twenty days after treatment initiation, MMP 3 was normalized. MMP 3 was more indicative of RS3PE syndrome symptoms than CRP. Thus, MMP 3 seems to be more sensitive to RS3PE syndrome symptoms.
Continuous Fermentation of a Prodigiosin Producing Serratia marcescens Strain Isolated from Soil
Year: 2019

A red pigmented bacterial strain NS 17 was isolated from soil, and physiological and biochemical characteristics and 16S rDNA analysis established this organism as a strain of Serratia marcescens. The red pigment isolated from cells of NS 17 was identified as prodigiosin. By analyzing factors affecting the production of prodigiosin, modified medium and culture conditions were set up, and a continuous fermentation method was carried out to take advantage of the mass production of foam during fermentation. Continuous fermentation was achieved in the following conditions: 32, 1:1 ventilation ratio, and medium with a nutrient concentration 5 fold higher than that of the fermentation medium (with half the inorganic salt concentration) supplied as a feed medium at a flow rate of 8 mL/min. For the first time of continuous fermentation of Serratia marcescens coupling with foam flotation, a high yield of prodigiosin was obtained. After 56 h of culturing, the total harvest of cells was enhanced 2.33 fold compared to that of batch fermentation, the total amount of prodigiosin was enhanced 2.70 fold compared to that of batch fermentation, and cells and prodigiosin were concentrated in the efflux broth automatically.
Current sample preparation methodologies for analysis of emerging pollutants in different environmental matrices
Year: 2016

Emerging contaminants such as pharmaceuticals, personal care products, and endocrine disrupting compounds are ever present in environmental matrices and they are known to pose negative effects on living organisms. The determination of these pollutants in different environmental matrices (such as water, soil, and sediments, among others) frequently requires separation techniques that are capable of high efficiency, unique selectivity and high sensitivity. However, direct analysis of these pollutants in complex matrices is difficult. For this reason, rapid, inexpensive, efficient and environmentally friendly sample preparation techniques have been developed prior to chromatographic quantification. Therefore, the aim of this article is to review recent publications (2010 2016) on modern sample preparation techniques combined with chromatographic techniques for identification and quantification of emerging pollutants in environmental matrices. These sample preparation techniques include solid phase extraction, solid phase microextraction, liquid liquid extraction, microwave assisted extraction, liquid phase microextraction techniques, stir bar sorptive extraction, and pressurized liquid extraction, among others.
