Semantics based approach for generating partial views from linked life cycle highway project data
Year: 2017

The purpose of this dissertation is to develop methods that can assist data integration and extraction from heterogeneous sources generated throughout the life cycle of a highway project. In the era of computerized technologies, project data is largely available in digital format. Due to the fragmented nature of the civil infrastructure sector, digital data are created and managed separately by di erent project actors in proprietary data warehouses. The di erences in the data structure and semantics greatly hinder the exchange and fully reuse of digital project data. In order to address those issues, this dissertation carries out the following three individual studies. The rst study aims to develop a framework for interconnecting heterogeneous life cycle project data into an uni ed and linked data space. This is an ontology based framework that consists of two phases: (1) translating proprietary datasets into homogeneous RDF data graphs; and (2) connecting separate data networks to each other. Three domain ontologies for design, construction, and asset condition survey phases are developed to support data transformation. A merged ontology that integrates the domain ontologies is constructed to provide guidance on how to connect data nodes from domain graphs. The second study is to deal with the terminology inconsistency between data sources. An automated method is developed that employs Natural Language Processing (NLP) and machine learning techniques to support constructing a domain speci c lexicon from design manuals. The method utilizes pattern rules to extract technical terms from texts and learns their representation vectors using a neural network based word embedding approach. The study also includes the development of an integrated method of minimal supervised machine learning, clustering analysis, and word vectors, for computing the term semantics and classifying the relations between terms in the target lexicon. In the last study, a data retrieval technique for extracting subsets of an XML civil data schema is designed and tested. The algorithm takes a keyword input of the end user and

Broken Rotor Bar Fault Detection of Induction Motors Using a Joint Algorithm of Trust Region and Modified Bare bones Particle Swarm Optimization
Venue: Chinese Journal of Mechanical Engineering
Year: 2019

A precise detection of the fault feature parameter of motor current is a new research hotspot in the broken rotor bar (BRB) fault diagnosis of induction motors. Discrete Fourier transform (DFT) is the most popular technique in this field, owing to low computation and easy realization. However, its accuracy is often limited by the data window length, spectral leakage, fence effect, etc. Therefore, a new detection method based on a global optimization algorithm is proposed. First, a BRB fault current model and a residual error function are designed to transform the fault parameter detection problem into a nonlinear least square problem. Because this optimization problem has a great number of local optima and needs to be resolved rapidly and accurately, a joint algorithm (called TR MBPSO) based on a modified bare bones particle swarm optimization (BPSO) and trust region (TR) is subsequently proposed. In the TR MBPSO, a reinitialization strategy of inactive particle is introduced to the BPSO to enhance the swarm diversity and global search ability. Meanwhile, the TR is combined with the modified BPSO to improve convergence speed and accuracy. It also includes a global convergence analysis, whose result proves that the TR MBPSO can converge to the global optimum with the probability of 1. Both simulations and experiments are conducted, and the results indicate that the proposed detection method not only has high accuracy of parameter estimation with short time data window, e.g. the magnitude and frequency precision of the fault related components reaches 10 4, but also overcomes the impacts of spectral leakage and non integer period sampling. The proposed research provides a new BRB detection method, which has enough precision to extract the parameters of the fault feature components.
Reducing risk for gestational diabetes among American Indian and Alaska Native teenagers: Tribal leaders' recommendations
Venue: International journal of gynaecology and obstetrics: the official organ of the International Federation of Gynaecology and Obstetrics
Year: 2021

Liquidity Risk Management and Credit Supply in the Financial Crisis
Year: 2011

Liquidity dried up during the financial crisis of 2007 2009. Banks that relied more heavily on core deposit and equity capital financing, which are stable sources of financing, continued to lend relative to other banks. Banks that held more illiquid assets on their balance sheets, in contrast, increased asset liquidity and reduced lending. Off balance sheet liquidity risk materialized on the balance sheet and constrained new credit origination as increased takedown demand displaced lending capacity. We conclude that efforts to manage the liquidity crisis by banks led to a decline in credit supply.

Politics and Mathematics
Year: 2013

The main theme of this chapter is the boycott of Germany after World War I. The newly founded Conseil internationale de recherches excluded scientists from the Ax's countries and barred them from conferences, and even discouraged contacts between their subjects and German/Austrian scientists. Brouwer took the internationalist position and tried to obstruct the policies of the Conseil wherever possible. This brought him into numerous conflicts, including one with the Utrecht professor A. Denjoy.
The development of a screening tool to evaluate gross motor function in HIV infected infants
Venue: AIDS care
Year: 2011

Neurodevelopmental delay or HIV encephalopathy is a stage four disease indicator for paediatric HIV/AIDS according to the World Health Organisation (WHO) and may be used as a criterion for initiation of highly active antiretroviral therapy (HAART) To date, the only means of prevention of this condition is early initiation of HAART. Studies which have been carried out in South African clinics have revealed the high prevalence of this condition. In developing countries, commencement of HAART is based on declining virologic and immunologic status, as standardised neurodevelopmental assessment tools are not widely available. A standardised developmental screening tool which is suitable for use in a developing country is therefore necessary in order to screen for neurodevelopmental delay to allow for further assessment and referral to rehabilitation services, as well as providing an additional assessment criterion for initiation of HAART. The infant gross motor screening test (IGMST) was developed for this purpose. The standardisation sample of the IGMST consisted of 112 HIV infected infants between six and 18 months of age. Item selection for the IGMST was based on the Gross Motor scale of the Bayley Scales of Infant Development (BSID) III. Content validity was assessed by a panel of experts using a nominal group technique (NGT; agreement >80% Concurrent validity (n=60) of the IGMST was carried out against the BSID III, and agreement was excellent (K=0.85) The diagnostic properties of the IGMST were evaluated and revealed: sensitivity 97.4% specificity 85.7% positive predictive value (PPV) 92.7% and negative predictive value (NPV) 94.7% Reliability testing (n=30) revealed inter rater reliability as: r=1, test retest reliability: r=0.98 and intra rater reliability: r=0.98. The results indicate that the statistical properties of the IGMST are excellent, and the tool is suitable for use within the paediatric HIV setting.
A Quick Gbest Guided Artificial Bee Colony Algorithm for Stock Market Prices Prediction
Venue: Symmetry
Year: 2018

The objective of this work is to present a Quick Gbest Guided artificial bee colony (ABC) learning algorithm to train the feedforward neural network (QGGABC FFNN) model for the prediction of the trends in the stock markets. As it is quite important to know that nowadays, stock market prediction of trends is a significant financial global issue. The scientists, finance administration, companies, and leadership of a given country struggle towards developing a strong financial position. Several technical, industrial, fundamental, scientific, and statistical tools have been proposed and used with varying results. Still, predicting an exact or near to exact trend of the Stock Market values behavior is an open problem. In this respect, in the present manuscript, we propose an algorithm based on ABC to minimize the error in the trend and actual values by using the hybrid technique based on neural network and artificial intelligence. The presented approach has been verified and tested to predict the accurate trend of Saudi Stock Market (SSM) values. The proposed QGGABC ANN based on bio inspired learning algorithm with its high degree of accuracy could be used as an investment advisor for the investors and traders in the future of SSM. The proposed approach is based mainly on SSM historical data covering a large span of time. From the simulation findings, the proposed QGGABC FFNN outperformed compared with other typical computational algorithms for prediction of SSM values.

Year: 2020

To investigate the effects of thoracoscopy guided thoracic paravertebral block for analgesia after single port video assisted pulmonary lobectomy.  From December 2019 to April 2020, 60 patients receiving single port video assisted pulmonary lobectomy at Ningbo Medical Center Lihuili Hospital were selected. The patients were randomly and equally divided into control group and paravertebral block group using a random number table. Patients of paravertebral block group were injected into the thoracic 4 5 intercostal, paravertebral 1 cm using 0.375% ropivacaine (20 ml) with thoracoscopy guided at the end of surgery, while patients of control group were given patient controlled intravenous analgesia (PCIA) Postoperative visual analogue scale (VAS) and Ramsay sedation scale were recorded at 6, 12, 24, 36, 48 h after the surgery. The incidence of postoperative adverse reactions, additional dose and times of pethidine, the time to resume eating, the rate of postoperative active cough, the first time to get out of bed after surgery and postoperative hospital stay of two groups' patients were recorded. t test and chisquare test were used for statistical analysis.  The VAS score of paravertebral block group were lower than those of control group at all time points (all P<0.05) The Ramsay sedation scale of paravertebral block group were higher than those of control group at all time points (all P<0.05) The additional dose and times of pethidine of paravertebral block group were (8.2+ 2.3) mg and (0.2+ 0.1) time, which were lower than (87.8+ 15.3) mg and (1.8+ 0.3) time of control group, the differences were statistically significant (t=28.91, 34.37, all P<0.05) Incidence of nausea, vomiting and pruritus of paravertebral block group were 10.0% 6.7% and 0, which were lower than 40.0% 30.0% and 13.3% of control group, the differences were statistically significant (kh(2)=7.20, 5.45, 4.29, all P<0.05) The rate of postoperative active cough of paravertebral block group was 33.3% which was higher than 10.0% of control group, the difference was statistically significant (kh(2)=4.81, P<0.05) The time to resume eating, the first time to get out of bed after surgery and postoperative hospital stay were (6.5+ 0.4) h, (20.9+ 3.1) h and (4.6+ 1.0) d, which were lower than (8.5+ 0.7) h, (28.6+ 4.8) h and (6.1+ 1.3) d of control group, the differences were statistically significant (t=13.47, 7.39, 4.19, all P<0.05)  Thoracic paravertebral block under thoracoscopy guided can effectively reduce the postoperative pain of single port thoracoscopic lobectomy, with fewer adverse reactions, and is beneficial to postoperative recovery.
Temperature Dependent Refractive Index, Thermo optic Coefficient and Birefringence of Negative Biaxial Imidazolium L Tartrate Non linear Optical Crystal
Year: 2021

Imidazolium L tartrate (IMLT) single crystal has been grown by slow cooling seed rotation technique. The temperature dependent refractive index (RI) has been measured along the principal axes in the temperature range 30 125 degC. The prism coupling technique has been used to determine the refractive index with accuracy 5x10 4. The transmission spectra depict good transparency in the range 340 1350 nm. The principal axes directions have been identified using polarized light microscopy. Principal directions have been found rotated by 44deg in the orthogonal xz plane with respect to the crystallographic x axis. The generalized temperature dependent equations for the Sellmeier's and thermo optic (dn/dT) coefficients have been determined. The thermo optic coefficients (TOC) in the above specified range have been found to be negative and are ~10 5 /degC. An important set of empirical relations between TOC and wavelength (407 1551 nm) has also been established which is useful for estimating TOC in the temperature range of 30 125 degC. Based on the birefringent measurement it has been confirmed that the IMLT crystal is a negative biaxial crystal.
Animal models of female sexual dysfunction: Basic considerations on drugs, arousal, motivation and behavior
Venue: Pharmacology Biochemistry and Behavior
Year: 2014

Female sexual dysfunctions are a heterogeneous group of symptoms with unknown but probably varying etiology. Social factors may contribute both to the prevalence and to the origin of these dysfunctions. The present review focuses on female hypoactive sexual desire disorder, sexual arousal disorder and orgasmic disorder. These disorders are generally the most common, according to epidemiological studies, and they can all be considered as disorders of motivation. An incentive motivational model of sexual behavior, applicable to humans as well as to non human animals, is described and the dysfunctions placed into the context of this model. It is shown that endocrine alterations as well as observable alterations in neurotransmitter activity are unlikely causes of the disorders. A potential role of learning is stressed. Nevertheless, the role of some transmitters in female rodent sexual behavior is analyzed, and compared to data from women, whenever such data are available. The conclusion is that there is no direct coincidence between effects on rodent copulatory behavior and sexual behavior in women. Based on these and other considerations, it is suggested that sexual approach behaviors rather than copulatory reflexes in rodents might be of some relevance for human sexual behavior, and perhaps even for predicting the effects of interventions, perhaps even the effects of drugs. Female copulatory behaviors, including the proceptive behaviors, are less appropriate. The common sexual dysfunctions in women are not problems with the performance of copulatory acts, but with the desire for such acts, by feeling aroused by such acts and experiencing the pleasure expected to be caused by such acts. Finally, it is questioned whether female sexual dysfunctions are appropriate targets for pharmacological treatment.
Generation and Characterization of Patient Derived Head and Neck, Oral, and Esophageal Cancer Organoids.
Venue: Current protocols in stem cell biology
Year: 2020

Esophageal cancers comprise adenocarcinoma and squamous cell carcinoma, two distinct histologic subtypes. Both are difficult to treat and among the deadliest human malignancies. We describe protocols to initiate, grow, passage, and characterize patient derived organoids (PDO) of esophageal cancers, as well as squamous cell carcinomas of oral/head and neck and anal origin. Formed rapidly <14 days) from a single cell suspension embedded in basement membrane matrix, esophageal cancer PDO recapitulate the histology of the original tumors. Additionally, we provide guidelines for morphological analyses and drug testing coupled with functional assessment of cell response to conventional chemotherapeutics and other pharmacological agents in concert with emerging automated imaging platforms. Predicting drug sensitivity and potential therapy resistance mechanisms in a moderate to high throughput manner, esophageal cancer PDO are highly translatable in personalized medicine for customized esophageal cancer treatments.

The neuroscience of empathy: progress, pitfalls and promise
Venue: Nature Neuroscience
Year: 2012

The last decade has witnessed enormous growth in the neuroscience of empathy. Here, we survey research in this domain with an eye toward evaluating its strengths and weaknesses. First, we take stock of the notable progress made by early research in characterizing the neural systems supporting two empathic sub processes: sharing others' internal states and explicitly considering those states. Second, we describe methodological and conceptual pitfalls into which this work has sometimes fallen, which can limit its validity. These include the use of relatively artificial stimuli that differ qualitatively from the social cues people typically encounter and a lack of focus on the relationship between brain activity and social behavior. Finally, we describe current research trends that are overcoming these pitfalls through simple but important adjustments in focus, and the future promise of empathy research if these trends continue and expand.
Efficient modeling of time cost trade off problem by eliminating redundant paths
Year: 2020

Time cost trade off (TCTO) is a traditional decision making problem in construction management. Numerous optimization techniques have been developed to solve such problem; however, they are not applicable to large sized projects. Although heuristic methods can handle large sized problems, they do not guarantee optimum solution. In a project network, the proper sequence of activities can be maintained by allowing a precedence constraint for each path. In practice, only small number of paths are dominant while others are redundant. In this paper, an efficient optimization model is developed to minimize project direct cost where redundant paths are eliminated, precise activity discrete time cost relationship is used and overlap between activities is permitted. The optimization model is formulated in the standard form of zero one programming. The model requires as inputs: discrete utility data of activities, precedence relationships and overlap between consecutive activities. Details of model formulation is illustrated by an example project and then is validated by a real life project. Based on the obtained results, the developed model is compared with traditional optimization models. The developed model guarantees optimal solution and can be applied efficiently to large sized projects. The proposed approach provides both academicians and practitioners with an efficient technique that produces optimal solution based on realistic assumptions.
Taking Global Administrative Law One Step Ahead: Online Giants and the Digital Democratic Sphere
Year: 2021

Today, societal speech activities are increasingly conducted online. Therefore, free speech concerns focus on the digital sphere. Major online service platforms operate speech moderation practices constraining digital speech. These platforms are run by a few multinational corporations the so called online giants. Online giants, in fact, control the backbone of democracies, on a global scale. Against this backdrop, this article stresses a potential legal path for appropriately regulating digital speech, while preserving the free and thriving global digital culture. The argument introduced is that the online giants should to a certain extent emulate global organizations, and since they control an essential public utility, they should operate under basic administrative law norms that include accountability, transparency, giving reason, and objective review. For this end, the article inspects the Global Administrative Law movement and proposes to extend its overarching conceptualization of global public procedural principles facilitating "good governance" to the online giants' procedures, despite their private ownership.
