Towards a gamete matching platform: using immunogenetics and artificial intelligence to predict recurrent miscarriage
Venue: npj Digital Medicine
Year: 2019

The degree of Allele sharing of the Human Leukocyte Antigen (HLA) genes has been linked with recurrent miscarriage (RM) However, no clear genetic markers of RM have yet been identified, possibly because of the complexity of interactions between paternal and maternal genes during embryo development. We propose a methodology to analyse HLA haplotypes from couples either with histories of successful pregnancies or RM. This article describes a method of RM genetic risk calculation. The proposed HLA representation techniques allowed us to create an algorithm (IMMATCH) to retrospectively predict RM with an AUC 0.71 (p 0.0035) thanks to high resolution typing and the use of linear algebra on peptide binding affinity data. The algorithm features an adjustable threshold to increase either sensitivity or specificity, allowing a sensitivity of 86% Combining immunogenetics with artificial intelligence could create personalised tools to better understand the genetic causes of unexplained infertility and a gamete matching platform that could increase pregnancy success rates.
A Long Lasting Reinforcement Learning Intrusion Detection Model
Venue: AINA
Year: 2020

Several works have proposed highly accurate network based intrusion detection schemes through machine learning techniques. However, they are unable to address changes in network traffic behavior over time. Authors often assume periodic model updates, but without taking into account the challenges they entail. This paper proposes a long lasting reinforcement learning model for intrusion detection that withstands long periods without model updates. Our proposal builds machine learning models through reinforcement learning to keep their accuracy for longer periods. Then, we cope it with a verification technique to ensure that only reliable classifications are accepted over time. Experiments performed using a dataset spanning a year of real network traffic, composed of 10 TB of data, show that the technique we propose remains reliable for ten months without model updates. Additionally, our proposal increases its accuracy when coped with the verification technique.
Speech Emotion Recognition among Couples using the Peak End Rule and Transfer Learning
Venue: ICMI Companion
Year: 2020

Extensive couples? literature shows that how couples feel after a conflict is predicted by certain emotional aspects of that conversation. Understanding the emotions of couples leads to a better understanding of partners? mental well being and consequently their relationships. Hence, automatic emotion recognition among couples could potentially guide interventions to help couples improve their emotional well being and their relationships. It has been shown that people's global emotional judgment after an experience is strongly influenced by the emotional extremes and ending of that experience, known as the peak end rule. In this work, we leveraged this theory and used machine learning to investigate, which audio segments can be used to best predict the end of conversation emotions of couples. We used speech data collected from 101 Dutch speaking couples in Belgium who engaged in 10 minute long conversations in the lab. We extracted acoustic features from (1) the audio segments with the most extreme positive and negative ratings, and (2) the ending of the audio. We used transfer learning in which we extracted these acoustic features with a pre trained convolutional neural network (YAMNet) We then used these features to train machine learning models support vector machines to predict the end of conversation valence ratings (positive vs negative) of each partner. The results of this work could inform how to best recognize the emotions of couples after conversation sessions and eventually, lead to a better understanding of couples? relationships either in therapy or in everyday life.
The Role of Education in Achieving Sustainable Development (Singapore is a Model)
Year: 2019

Development depends on many factors, including capital, natural resources, technical progress, political, social, cultural and economic conditions, and the degree of awareness of members of society. Development needs are not limited, but it depends mainly on the manpower needed. In view of the fact that development projects depend to a large extent on the provision of its needs of individuals according to the required skill levels, thus we must give high priority to education in all its stages and levels, meeting its requirements, fulfilling its requirements, and allocating a large part of the state budget to it; all that because of its impact and the close link between its level and the ranking of the state in the development ladder. Development must be all encompassing and sustainable, where real and effective development is not confined to one side, since development must be comprehensive in its economic and social aspects, with its various axes and elements including health, education, employment, adequate income, satisfaction of basic needs and the ability to give and innovate. t`tmd ltnmy@ `l~ `wml `dyd@ mn Dmnh r's lml, lmwrd lTby`y@ wltqdm ltqny wlZrwf lsysy@ wljtm`y@ wlthqfy@ wlqtSdy@ wdrj@ lw`y ld~ 'frd lmjtm` fHjt ltnmy@ l tnHSr. wlknh t`tmd 'ss `l~  wmstwyth wyf mtTlbth. wSrf wtkhSyS qsm kbyr mn myzny@ ldwl@ lh lm lh mn 'thr wrtbT wthyq byn mstwh wtrtyb ldwl@ `l~ slm ltnmy@ wyjb kdhlk l'mr 'n tkwn ltnmy@ shml@ bkf@ 'nw`h w'n tkwn kdhlk mstdm@ fltnmy@ lHqyqy@ wlf`l@ l tqtSr `l~ jnb dwn akhr, dh yjb 'n tkwn ltnmy@ shml@ fy jwnbh lqtSdy@ wljtm`y@ wm ttDmnh mn mHwr w`nSr `dyd@ tshml lSH@ lt`lym wl`ml wldkhl lkfy wshb` lHjt l'ssy@ wlqdr@ `l~ l`T wlbd`
Affordable Ink Jet Printed Antennas for RFID Applications
Venue: IEEE Transactions on Components, Packaging and Manufacturing Technology
Year: 2012

With the increasing demands of radio frequency identification (RFID) applications, an alternative ink jet printing technique for RFID tag antenna is demonstrated. Commercially available ink jet printers are adapted for conductive printing, in order to minimize manufacturing cost. Paper based dipole antenna and dipole with a tuning stub antenna were designed. The antennas were ink jet printed and assembled with RFID chips. The performances of the fabricated tags were measured through the reading range. With reference to equivalent isotropically radiated power of 4 W at 923 MHz, the reading range of tag with dipole antenna is around 9 m and of tag with dipole with a tuning stub is nearly 13 m. These performances are comparable to those of commercial tags. The advantages of the proposed printing technique are simplicity, flexibility and, more importantly, affordability. The technique can, in addition, contribute to further development and enhance extension of RFID applications.
RhIII Catalyzed Olefination of 2 Aryloxypyridines Using 2 Pyridyloxyl as the Removable Directing Group
Year: 2015

An efficient RhIII catalyzed trans selective ortho olefination of 2 aryloxypyridines has been developed. The catalytic system is very effective for olefination of differently substituted 2 aryloxypyridines with acrylates, acrylamide and styrenes and exhibits broad compatibility with assorted olefinic coupling partners. Although acrylates and acrylamide give rise to trans olefinated products in MeOH, styrenes provided the trans products under solvent free reaction conditions. Interestingly, in olefinations with ethyl acrylate, the aryloxypyridine compound bearing keto functionality at the ortho position was found to undergo directing group cleavage to afford the olefinated phenol product directly.
Teacher Perceptions of Skills, Knowledge, and Resources Needed to Promote Social and Emotional Learning in Rural Classrooms
Year: 2021

The incorporation of social and emotional learning (SEL) in schools has been shown to improve academic and psychological health of students. Research has been limited regarding implementation of SEL programs in rural communities, where student needs are heightened. The current study examined factors that could impact teachers' intentions to be early adopters of a SEL curriculum in a rural community. Seventy six teachers provided self report data regarding perceptions of professional strengths, school climate, school resources for student support, ability to educate diverse students, ability to teach specific SEL domains, and intentions to be an early adopter of a SEL program. Present results indicated positive perceptions of school climate, one's ability to teach diverse students, and one's ability to teach self management skills positively predicted intentions to be an early adopter of a SEL curriculum. Implications for rural schools are explored and recommendations for adoption of SEL curricula in rural schools are provided.
FA3C: FPGA Accelerated Deep Reinforcement Learning
Venue: ASPLOS
Year: 2019

Deep Reinforcement Learning (Deep RL) is applied to many areas where an agent learns how to interact with the environment to achieve a certain goal, such as video game plays and robot controls. Deep RL exploits a DNN to eliminate the need for handcrafted feature engineering that requires prior domain knowledge. The Asynchronous Advantage Actor Critic (A3C) is one of the state of the art Deep RL methods. In this paper, we present an FPGA based A3C Deep RL platform, called FA3C. Traditionally, FPGA based DNN accelerators have mainly focused on inference only by exploiting fixed point arithmetic. Our platform targets both inference and training using single precision floating point arithmetic. We demonstrate the performance and energy efficiency of FA3C using multiple A3C agents that learn the control policies of six Atari 2600 games. Its performance is better than a high end GPU based platform (NVIDIA Tesla P100) FA3C achieves 27.9% better performance than that of a state of the art GPU based implementation. Moreover, the energy efficiency of FA3C is 1.62x better than that of the GPU based implementation.
Hybrid deep reinforcement learning based eco driving for low level connected and automated vehicles along signalized corridors
Year: 2021

Eco Driving has great potential in reducing the fuel consumption of road vehicles, especially under the connected and automated vehicles (CAVs) environment. Traditional model based Eco Driving methods usually require sophisticated models and cannot deal with complex driving scenarios. This paper proposes a hybrid reinforcement learning (RL) based Eco Driving algorithm considering both the longitudinal acceleration/deceleration and the lateral lane changing operations. A deep deterministic policy gradient (DDPG) algorithm is designed to learn the continuous longitudinal acceleration/deceleration to reduce the fuel consumption as well as to maintain acceptable travel time. Collecting the critic's value of each single lane from DDPG and integrating the information of adjacent lanes, a deep Q learning algorithm is developed to make the discrete lane changing decision. Together, a hybrid deep Q learning and policy gradient (HDQPG) method is developed for vehicles driving along multi lane urban signalized corridors. The method can enable the controlled vehicle to learn well established longitudinal fuel saving strategies, and to perform appropriate lane changing operations at proper times to avoid congested lanes. Numerical experiments show that HDQPG can reduce fuel consumption by up to 46% with marginal or no increase of travel times.
Low income children's readiness for group based learning at age 3 and prekindergarten outcomes at age 5
Year: 2020

Although 3 year olds in the United States may attend prekindergarten prior to formal school entry in kindergarten, few investigations focus on the socioemotional foundations of classroom learning at age 3 and their relationship to later achievement. This study examined the relationship between age 3 readiness for group based learning, modeled as the latent constructs, effortful control and social communication, and age 5 classroom adjustment and pre academic outcomes. Data from the Early Head Start Research and Evaluation Project in the United States (n 797) included observations, direct assessment, and examiner and teacher report. Children's effortful control predicted classroom adjustment and their social communication predicted pre academic outcomes. Readiness for group based learning provides a way to describe key constructs of early skill development and a framework to support children's classroom learning. Implications include promoting parents' and educators' capacities to support early developmental foundations for later adjustment and learning by fostering infants' and toddlers' effortful control and social communication. Efforts to support these skills simultaneously across diverse experiences in the home and classroom by focusing on children's individual needs may prove advantageous.
miR 122 enhances sensitivity of hepatocellular carcinoma to oxaliplatin via inhibiting MDR1 by targeting Wnt/b catenin pathway.
Venue: Experimental and molecular pathology
Year: 2019

Hepatocellular carcinoma (HCC) is one of the primary causes of cancer related death and resistance to cytotoxic chemotherapy is the major cause of mortality in HCC patients. miR 122 is a liver specific miRNA and is found to be reduced in HCC, however, the function of miR 122 in HCC chemosensitivity remains elusive.  We used qRT PCR to measure expressions of miR 122, b catenin and MDR1 in four HCC cell lines. And we assessed the effects of miR 122 or b catenin on cell viability and apoptosis upon oxaliplatin (OXA) treatment by MTT assay and flow cytometry. In addition, we validated the interactions of miR 122/b catenin and b catenin/MDR1 by dual luciferase reporter assay and chromatin immunoprecipitation (ChIP) Western blotting was used to determine the protein levels of b catenin, Wnt1 and MDR1. In the end, we verified the anti tumor effect of miR 122 in vivo by using mouse tumor xenograft model.  We found that miR 122 was down regulated in HCC cells. Up regulation of miR 122 or inhibition of Wnt/b catenin signaling promoted HCC cells apoptosis and increased the sensitivity of HCC cells to OXA. On the molecular level, we showed that miR 122 directly targeted and suppressed Wnt/b catenin pathway while b catenin bound with MDR1 promoter and activated its transcription. Overexpression of miR 122 inhibited MDR1 expression via directly suppressing Wnt/b catenin pathway.  Our study fully demonstrated that miR 122 inhibits MDR1 expression via suppression of Wnt/b catenin pathway, thereby enhancing HCC sensitivity to OXA. Therefore, miR 122 could serve as a novel potential therapeutic target for HCC.

CRM Success Factors in Software Services firm: A Case Study Analysis
Year: 2012

This study is undertaken to gain better understanding of Customer Relationship Management (CRM) success factors in software service and Information Technology (IT) companies. The literature on CRM gives the impression of being inconsistent. The objective is to uncover the success factors associated with a CRM project. A case study involving a Bangalore based IT company which had implemented CRM, was done. Semi structured interview method was adopted for gathering data. The key finding is that effective leadership is critical for CRM success. The study confirms that the people, process and technology factors are crucial for a CRM program. IT companies are emerging significantly all over the world especially in Asia. These companies operate in a very competitive market and there is a need to distinguish a service from the competition, for survival. The effective use of CRM systems to improve service, performance, customer satisfaction and productivity is essential. However, the success factors for CRM in the service industry have not yet been studied. The value of this paper is that it illustrates how a case study approach can be used to understand the real CRM success factor in software service firms.

Lower Cretaceous sauropod trackways from Lishui City and an overview of dinosaur dominated track assemblages from Zhejiang Province, China
Venue: Journal of Palaeogeography
Year: 2018

A relatively small number of tetrapod tracksites from Zhejiang Province fills out the fossil record from that region, which is also known to have yielded both saurischian (titanosauriform, coelurosaur) and ornithischian (basal ornithopod, ankylosaurian) body fossils as well as dinosaurian eggs. We use photogrammetry and 3D imaging to reinterpret the sauropod tracks from Lishui City, which revealed the existence of trackways. The track record from three documented sites in Zhejiang Province includes avian and non avian theropod, sauropod, ornithopod and pterosaur tracks. Previous work showed that the purported new bird ichnospecies Dongyangornipes sinensis is a synonym of Uhangrichnus chuni, while we here consider Pteraichnus dongyangensis as a nomen dubium. Such "provincial ichnotaxonomy" may mask similarities in the ichnofauna across large regions. In fact, we show that the ichnofauna is similar to that found in the Early Cretaceous elsewhere in China.
Impact of Gastric Bypass on Erosive Esophagitis and Barret's Esophagus
Venue: Obesity Surgery
Year: 2020

The association between gastroesophageal reflux disease (GERD) and obesity is clearly defined. The incidence of erosive esophagitis (EE) and Barrett's esophagus (BE) are as high as 26 and 6% respectively. Gastric bypass (GBP) is considered the gold standard for obese patients with GERD. Evidence about the impact of GBP on EE and BE is not yet clear but more inspiring every day.  Obese patients operated by GBP with EE or BE were included for this study. Demographics, BMI, %EWL, and the evolution of EE and BE with pre and postoperative upper endoscopy were analyzed.  In this study, 64 patients were included, 55 with EE and 9 with BE. The preoperative BMI was 44.29 km/m 2 3.5 and the %EWL was 78.5 5.8 in the first year postoperative. Preoperatively, EE was distributed as follows: A: 54.5% (30) B: 34.5% (19) C: 9% (5) D: 2% (1) BE findings were the following: short segment (SSBE) 45% (4) and long segment (LSBE) 55% (5) Postoperatively, 80% of the patients with EE resolved their condition, 11% improved, 7% had no changes, and 2% worsened. From the patients with SSBE, 75% resolved their condition and 40% with LSBE resolved their condition after 24 months and no patient progressed to dysplasia.  Patients with EE had a statistically significant resolution after GBP. BE was improved or even resolved in many patients without acquiring significance but also without progression. Long term surveillance data is necessary to define the certain evolution of EE and BE after GBP.
Web markers for various tour products The case of Hong Kong
Year: 2013

A tourist attraction system consists of the nucleus or attraction, tourists and markers. Markers are pieces of information that connect the tourist to the attractions. While being recognized as the most influential component of the system, commercial markers have received relatively little attention. This extended research note examines the nature, type and content of website markers used in 91 different Hong Kong tour products that cover four different styles of tours: all inclusive multi destination tours; all inclusive Hong Kong specific tour modules; general sightseeing day tours; and special interest day tours. A shift from generic to specific markers, along with a clear shift from presenting superficial descriptions to encouraging action was observed when going from multi destination all inclusive tours to more specialized day tours. The research note concludes further that the former tend to be more aspirational while the latter tend to be more explicit and enlightening.
Contexte de gestion et presence de comportements harcelants percus en milieu scolaire
Year: 2019

Cette etude porte sur l'incidence du style de gestion, de la gestion des conflits et du stress sur la presence de comportements harcelants en milieu scolaire. Plus precisement, le lien entre le style de gestion de la direction d'ecole primaire et la presence de comportements harcelants chez les enseignants a ete etudie. Les analyses statistiques demontrent l'effet de protection que fournit le leadership transformationnel face aux comportements de harcelement psychologique. Cependant, en ce qui concerne les autres composantes du style de gestion, l'etude ne revele aucun lien significatif avec les comportements harcelants. Somme toute, cette recherche permet de mieux comprendre l'incidence du contexte scolaire quant a l'avenement de comportements harcelants et permet d'entrevoir de nouvelles mesures de prevention.
