HIV combi PT assay for screening and eliable early detection of HIV-1 infection in Asia

Background: The Elecsys® HIV combi PT assay was developed to allow earlier detection of HIV infection with increased sensitivity and specificity. Objectives: To validate the assay for screening and reliable early detection of HIV-1 infection in Asia. Study design: Samples tested reflected those routinely screened in Asia and comprised: HIV-1 antigen lysate (25 samples) and antibody (20 samples) dilutions; seven HIV-1 seroconversion panels (46 samples); 39 patient samples from early infection; 183 known-positive sera; HIV-1 p24 antigen sensitivity panel (seven samples); >500 routine clinical samples per center. The Elecsys® HIV combi PT assay was compared with fourth(ADVIA Centaur® HIV combo, ARCHITECT® HIV combo, Elecsys® HIV combi) and third-generation (VIRONOSTIKA® HIV Uni-Form II Plus O, Zhuhai Livzon Anti-HIV EIA, Serodia® Particle Agglutination) assays commonly used in the region. Results: Overall, the Elecsys® HIV combi PT showed superior or similar sensitivity to the comparators for detecting all subtypes. The assay correctly identified all positive samples, including those taken soon after infection, and detected seroconversion at a similar or shorter time interval than the comparators. The analytical sensitivity of Elecsys® HIV combi PT for HIV-1 p24 antigen was 0.90 IU/mL, which was lower than reported previously. The assay showed good specificity (99.86%) that was superior or equivalent to the other fourth-generation assays tested.

Taxonomic updates for some confusing Micronesian species of Camponotus (Hymeno- ptera: Formicidae: Formicinae)

Indo-Pacific members of the speciose and morphologically confusing group of Camponotus ants that resemble C. maculatus (FABRICIUS, 1782) have recently been the subject of a molecular phylogeny, and that analysis is used here as guidance to update the taxonomy of the Micronesian species. It is now known that Micronesian and some Melanesian specimens previously identified as C. chloroticus EMERY, 1897 are not closely related to Polynesian, Fijian, and Melanesian specimens identified by the same name, and that the form on Palau presently identified as C. irritans kubaryi MAYR, 1876 is not closely related to C. irritans (SMITH, F., 1857). We therefore examined the morphologies of 185 specimens previously assembled for molecular analysis, plus five C. chloroticus and two C. kubaryi syntypes. Principal component analyses were conducted to understand shape differences and match modern specimens to types. The syntypes of C. chloroticus, which are from Tonga and southeastern New Guinea, matched the species that is today represented by collections from Polynesia, Fiji, and Melanesia. Thus, specimens mostly from Micronesia and formerly identified as C. chloroticus are here described as Camponotus micronesicus sp.n. In addition, C. kubaryi stat. rev. is returned to species status, and Camponotus tol sp.n. , a new species from the Micronesian island of Chuuk, is described.
MODELLING AND OPTIMIZATION ANALYSIS OF COMPOSITE TAPE SPRING

To obtain a better composite design of tape spring, an optimization process is given in this paper. A representative unit cell of plain woven composite material is established using TexGen. Through the finite element analysis the equivalent elastic constants are extracted. Based on classic laminate theory the ABD matrix of symmetric ply laminate is derived and assigned to tape spring. The bending moment and strain energy of tape spring made of the foregoing composite materials are investigated. A multi-objective optimization model is established with constraints of critical moment and longitudinal strain. After solved using the modified Non-Dominated Sorting Genetic Algorithm (ASGA-II), the optimal design is obtained and then it is simulated and compared to the optimal solution, results show that there are differences being less than 1%, which indicates the optimal design is accurate.
Binary 2D Morphologies of Polymer Phase Separation: Dataset and Python Toolbox

Study of the intricate connection between the design of material distributions (also called morphology or microstructure) and the final properties of the material system has been an attractive research theme for material science community. Such analysis provides ability to synthesize the microstructures exhibiting desired properties. This theme encompasses several material systems including porous materials [26], steels and welds [2], composites [14], powder metallurgy [28], 3D printing [22], energy storage devices as batteries [10], and energy converting devices like bulk hetero-junction solar cells [20]. Microstructure-sensitive design has been used to tailor a wide variety of properties including strengths, heat and mass diffusivities, energy storage capacity and lifetime, and energy conversion efficiency.

Performance Evaluation of Workflows Using Fluid Flow Approximation of Discrete Sets and Probability Distributions

How to make information systems safe, dependable and trustworthy is one of central concerns in the development of e-Society and e-Government. In this paper, we focus on the problem of guaranteeing performance of workflow-based information systems. Performance evaluation by traditional stochastic approaches such as queuing models and stochastic Petri nets is costly, and is hard to be applied to workflow systems in which many instances of flows run simultaneously. We develop a novel method for deriving performance indices from hybrid- system models in which each discrete set is approximated by a continuous region on a real-valued vector space and the variance of each probability distribution is represented by a real-valued interval. To prevent approximated ranges from divergence, we use place invariants as constraints on the state space. Paper review processes in an academic journal are used as a case study.
PREDICTING STUDENT ATTRITION USING DATA MINING PREDICTIVE MODELS 1

This paper demonstrates how educational data mining can help institution in decision-making specifically to reduce student attrition. Phases of CRISP-DM (Cross Industry Standard Process for Data Mining) methodologyare followed in order to determine students at-risk of dropping out after the first semester in their freshmen year. Predictive models namely, decision tree, naïve bayes, and rule induction were built and applied to process the data set. Subsequently, these models were tested for accuracy using 10-fold cross validation. Results show that, given sufficient data and appropriate variables, these models are capable of predicting freshmen attrition with roughly 80% accuracy. Moreover, the average grades of the students can be used as predictor in determining student attrition unlike the gender attribute that yielded no significant result.
Blood culture and antimicrobial susceptibility pattern of bacteria and fungi isolated from febrile neutropenic patients treated with chemotherapy at Taleghani hospital, Tehran

Background and Objectives: The aim of this study was to determine the drug susceptibility pattern of the pathogens causing bacteraemia and fungemia in patients who have developed febrile neutropenia after chemotherapy. Materials and Methods: A total of 95 patients with suspected or proven malignancy (50 patients) were admitted to the adult haematology ward at Taleghani Hospital in Tehran. Blood samples were inoculated into the bottles of Bact/Alert blood culture system and sent to Payvand's clinical and special laboratory immediately and then incubated at 35 ± 2°C. Culture from positive bottles were plated on appropriate media and incubated at 37°C and 30°C for bacterial and fungal isolation, respectively. A bacterial suspension with turbidity equal to 0.5 McFarland (1.5 × 108 CFU/mL) was prepared and used for the Vitec2 system (biomerioux). Statistical analysis using independent Fisher's exact test was conducted and a p-value of < 0.05 was considered as significant. Results: Among 50 patients with approved malignancy, Acute Lymphoblastic Leukaemia (ALL) and Acute Myeloid Leukaemia (AML) were the most common underlying diseases. This study showed, 20% (n: 10) of febrile neutropenic episodes established positive blood culture. Of them, 3 were Gram-negative (30%) and 5 were-Gram-positive bacteria (50%) and 2 patients (20%) showed fungemia with Fusarium spp. Conclusion: It is crucial to know about the likely pathogens and their local antibiotic and antifungal sensitivity patterns. Such local findings will show if any modifications to treatment guidelines are necessary.
Probabilistic Graphical Models Spring 2017 17 : Optimization and Monte Carlo Methods

Monte Carlo methods such as rejection sampling and importance sampling allow us to compute the expectation of functions of random variables. They can also be used to simply obtain samples from the underlying distribution. In graphical models, they can be used to perform inference, even when we cannot compute the marginal distribution or the partition function directly. However, there are several limitations of Monte Carlo methods. One important issue is that the performance of Monte Carlo methods relies heavily on having good proposal distributions, which are difficult to find when the true distribution is complex and/or high-dimensional. For example, in rejection sampling and importance sampling, the proposal distribution is fixed throughout the sampling procedure. This means that if the proposal distribution does not capture the true distribution sufficiently well, the algorithm will propose a lot of bad samples and the acceptance rate will be low.
CORRELATES OF SUBJECTIVE GLOBAL MARITAL SATISFACTION IN WOMEN

Seven hundred and seventy marriage couples in the city of Zagreb were included in the study of potential predictors of marriage satisfaction. Marriage satisfaction was defined as a global feeling of satisfaction in marriage (measured by 1-item 5-point scale), and only wife’s marital satisfaction was measured. Seventy seven potential predictors grouped in 5 blocks were entered into hierarchical and step-wise hierarchical regression. The blocks were: premarital partners’ characteristics, both partners’ perception of marital processes, objective and subjective economic status of the family, objective marital characteristics and outof-marriage influences. Five blocks of predictors explained 47% of dependent variable variance, with the block marriage processes contributing the most. The most important predictors of wife’s global marital satisfaction proved to be wife’s perception of sexual intimacy in marriage, love for husband, feeling of being loved by husband but also husband’s perception of sexual intimacy in marriage, and his less participating in raising children and strategic decision making.
Oligomerization of p53 Precedes its Association with Dynein and Nuclear Accumulation

Previous studies have identified several proteins that associate with microtubules and the dynein motor complex including p53, the glucocorticoid and the vitamin D receptors, and the APC (adenomatous polyposis coli) protein; but neither the residues important for this interaction nor the physical state of the proteins involved have been clarified. We observed in SN12C cells harboring a mutant p53 truncated at amino acid 336, impaired nuclear localization and impaired association with dynein. This finding was confirmed and extended by examining a series of truncated p53 proteins that identified residues 336 to 348 as crucial for association with dynein and nuclear transport. Point mutations identified the importance of residues involved in p53 oligomerization in this process, establishing a p53 oligomer as the cargo for dynein transport. The association of cytosolic p53 oligomers with dynein occurs independent of microtubules indicating that following this association, the p53/dynein complex then associates with microtubules and is transported to the peri-nuclear region. These studies suggest that mutations or modifications that affect p53 oligomerization not only interfere with DNA binding but also with its intracellular distribution. They also highlight the importance of an intact microtubule network in the trafficking of crucial cellular proteins.
Dance / Movement therapy and resilience building with female asylum seekers and refugees : a phenomenological practice based research

Key implications for practice Dance/Movement therapy focusses onthebody to strengthenandcomplement psychosocial mental health programmes for refugees and asylum seekers Movement based interventions can help maintain and strengthen resources and contribute to resilience building Dance/Movement therapy can be adapted tovarious cultural contexts, settings and populations This phenomenological study aims to better understand the applicability of Dance/Movement therapy for traumatised women asylum seekers and refugees. It explores if and how bodily engagement could support an existing resilience based treatment model employed at a centre for transcultural psychiatry in the Netherlands. The sessions focused on moving thebodyand included the use ofmusic, props, mirroring techniques, body awareness and movement exploration exercises. Participation in the sessions was associated with self-reported alleviation of stress and addressed vulnerabilities. Additionally, movement and bodily engagement o¡ered opportunities for body awareness, and interconnectedness with other group members. A key ¢nding was that Dance/Movement therapy provided a shared safe psychological space for self-expression among this vulnerable population, and can be incorporated into a resilience based treatment programme with adaptations for context.
Capelin Stock Assessment in NAFO Divisions 3NO Based on Data from Trawl Surveys

The purpose of this work is to assess the current state of capelin stock in Divisions 3NO. Indices of capelin trawl biomass obtained in Canadian random-stratified bottom trawl surveys are the only available at the present time indicators of capelin stock dynamics. In 2007, trawl biomass of capelin in Divisions 3NO was 29.2 thousand tons. In 2008 trawl biomass increased sharply and was 114.6 thousand tons tons, that corresponded to the highest level of the stock since 1996. The average catch in 2007-2008 per 1 km was 0.41 t and 1.56 t. The estimate in 2008 corresponds slight increase of the stock observed in 1994. Fishery was conducted in the years when this value was equal or higher than 2 t/km. Capelin stock in Divisions 3NO remains at the very low level. Introduction Estimation of capelin stock (Mallotus villosus) in Divisions 3NO was based on the results of Russian and Canadian acoustic surveys conducted before 1993. In all subsequent years, data on capelin by-catch in Canadian trawl surveys of demersal fish has been the only source of data on state of capelin stock. Before 1995, Yankee 41-5 trawl and Engel 145 Hi-Lift trawl were used. Since autumn 1995, Campelen 1800 shrimp trawl has been applied as standard sampling gear. After taking in use a new trawl, by-catches of capelin increased greatly and this made it even more difficult to interpret the obtained results. Since capelin is a pelagic fish species, a bottom trawl cannot be used as adequate sampling gear for quantitative estimation of the stock. Therefore, relationship between biomass indices from bottom trawl survey and stock size remains unclear. As analytical methods could not be applied, the purpose of this work was to estimate current state of capelin stock in the Divisions 3NO according to the available indirect data. Fishery and management Fishery for capelin started in 1971 and total catch was maximal in mid-1970s with the highest catch of 132 000 tons in 1975. The fishing was closed in 1979-1986 and then reopened in 1987-1992. Annual catches in this period did not exceed 25 000 tons. In subsequent years due to abrupt decline of the stock size, the target fishery for capelin was banned. Highest historical catches were taken by Russia (former USSR), Norway, Iceland and Japan (Table 1). TAC of capelin was set for the first time in 1974 and in 1977-1978 it reached 200 000 tons, then TAC was reduced to 30 000 tons in 1990-1992. Considering that the catch did not exceed TAC in the whole regulation period, the decline of stock size observed since early 1990s could hardly be caused by overexploitation of the stock. A similar idea about capelin stock in NAFO Subareas 2 and Divisions 3KL was expressed by J. Carscadden (DFO, 2000). Because of dramatic decline of the capelin stock size since 1993, the ban on target fishery for capelin was imposed as a regulation measure.
An Improved Method of Measuring Spatial Resolution of the Computed Tomography from ESF based on CT phantom images

Spatial resolution is an important feature of the computed tomography (CT) imaging system, which is the ability of an image to convey details and distinguish between small objects that are close together. In this paper, a simple developed methodology for measuring the spatial resolution of CT images is implemented using phantom images. The present study offers an alternative methodology to the measurement of the spatial resolution of CT machine which is based on the calculation of the full width at half maximum (FWHM) of the line spread function (LSF) acquired from a function called the edge spread function (ESF). The ESFs data were constructed from the CT image obtained by scanning phantom made of silicone rubber shaped as a cylindrical containing different material. The ESF curves were obtained by a direct fit of a mathematical expression of the ESF profile using MATLAB (R2015b) to the ESF data acquired at the interface between the different materials within the experiment phantom. The proposed methodology can be implemented using signal data from the reconstructed CT image and is not sensitive to the noise introduced by differentiating the ESF to produce the LSF as noted in the previous measurement. In addition, the proposed methodology provides a practical measurement of CT machine spatial resolution.

Comment Text Analysis with Improved Feature Weight

In the product reviews of online shopping platforms, the star rating and text comments given by the same user often appear. These data are processed by the unreasonable scoring system to give the merchants a false rating and mislead consumers. In order to improve the scoring system, an improved feature weighting method combining text review content and star rating is proposed. Firstly, the weighting rules were defined. Secondly, according to the part-of-speech evaluation function in the short text, the feature word selection was combined with the star rating and the text comment content. The CBOW model was used to train the word vector. Finally, the text classification method SVM was used to obtain the final result. This model was applied to two text datasets and compared with the traditional TF-IDF feature selection. The results show that the algorithm can effectively improve the accuracy and F1 value of text classification.
2 Insider Trading Around Open Market Share Repurchase Announcements

Open market share buyback announcements are generally viewed as a signal of firm undervaluation; however these announcements can be employed opportunistically to mislead investors. Repurchase announcement will be a more credible undervaluation signal when it is supported by insiders’ actions. Consistent with this I find that the market reacts more positively to buyback announcements when insiders trade parallel to their repurchase signal before the announcement. However, analysis of post-announcement insider trades suggests that insiders take advantage of higher post-announcement price and sell more heavily. This is especially true for firms that are more (less) likely to be overvalued (undervalued). The negative relationship between postannouncement insider sales and longer-term returns indicates firms with higher insider sales under perform in the long-run. a Assistant Professor at Warwick Business School, the University of Warwick, United Kingdom.

A bitstream-based, scalable video-quality model for HTTP adaptive streaming: ITU-T P.1203.1

The paper presents the scalable video quality model part of the P.1203 Recommendation series, developed in a competition within ITU-T Study Group 12 previously referred to as P.NATS. It provides integral quality predictions for 1 up to 5 min long media sessions for HTTP Adaptive Streaming (HAS) with up to HD video resolution. The model is available in four modes of operation for different levels of media-related bitstream information, reflecting different types of encryption of the media stream. The video quality model presented in this paper delivers short-term video quality estimates that serve as input to the integration component of the P.1203 model. The scalable approach consists in the usage of the same components for spatial and temporal scaling degradations across all modes. The third component of the model addresses video coding artifacts. To this aim, a single model parameter is introduced that can be derived from different types of bitstream input information. Depending on the complexity of the available input, one of four scaling-levels of the model is applied. The paper presents the different novelties of the model and scientific choices made during its development, the test design, and an analysis of the model performance across the different modes.
