Low Density Regions of DNA in Human Sperm Appear as Vacuoles after Translucent Staining With Reactive Blue 2

Human sperm often contain vacuoles, and it is therefore necessary to determine whether vacuoles in the chromosomal region are responsible for DNA deterioration. To that end, the present study developed a novel clinical examination technique, translucent staining, for the visualization of vacuoles. Highly diluted Reactive Blue 2 (RB2, 100 pmol/L) faintly stained the sperm head to reveal a translucent bluish body with toneless spots. Differential interference contrast showed the vacuoles as shaded-relief images. In the same, field of view the localization and the shape of the toneless spots were coincided with the shaded-relief images. Dual staining with RB2 and DNA fluorescent dye suggested that the vacuoles might include vacant or lowdensity DNA. The present results revealed important issues in clinical Assisted Reproductive Technology (ART), that is, a variety of vacuoles were involved regardless of the normalcy of outline or the motility. Features were classified into three categories: zero or one small vacuole; multiple sporadic vacuoles of various sizes; and one large vacuole. Moreover, in vitro processing steps such as density gradient centrifugation and subsequent swim up could not isolate sperm without vacuoles. Since it is still unknown whether the vacuoles merely push out DNA to the surroundings without damaging it, or if the empty region is a consequence of DNA degradation, the translucent staining for simultaneous visualization of the outline and vacuoles constitutes a major step for pre-ART cyto-diagnosis to determine whether the sperm population is competent for use in clinical ICSI.
’ s repository of research publications and other research outputs Hopefully We Are Mostly Secure : Views on Secure Code in Professional Practice Conference or Workshop Item

Security of software systems is of general concern, yet breaches caused by common vulnerabilities still occur. Software developers are routinely called upon to ”do more” to address this situation. However there has been little focus on the developers’ point of view, and understanding how security features in their day-to-day activities. This paper reports preliminary findings of semi-structured interviews taken during an ethnographic study of professional software developers in one organization who are not security experts. The overall study aims to understand how security features in day-to-day practice, while analysis of the interview data asks whether developers are responsible for security. The study reveals that awareness around security matters is raised through several paths including processes, standards, practices and company training and that a focus on security is driven by contextual factors. Security is taken care of with policies and through safeguards, and is handled differently depending on whether a team is developing new features, and hence ”looking forward”, or working with existing code and hence ”looking back”. Developers take and share responsibility for security in the code, but suggest that their responsibility has limits, and relies on collective practice.
The Role of Organizational Commitment as Mediator of Organizational Culture and Employees’ Competencies on Employees’ Performances (A Study on Irrigation Area Management in Southeast Sulawesi)

This study aims to analyze and explain the role of organizational commitment and organizational culture as mediator of employees’ competencies on employees’ performances of Irrigation Area Management in Southeast Sulawesi. The analysis in this study is Structural Equation Modeling (SEM), the results of this study is on the relationship between the variables which does not affect significantly. The employees’ competencies on employees’ performances means that the employees’ competencies of Irrigation Area Management in Southeast Sulawesi province does not have an impact on employees’ performance improvement, so in order to increase employees’ performances, it is needed an improvement on organizational commitment. The study also considers at organizational commitment as mediation is able to strengthen organizational culture on performance improvement.
Quantification of Scenario Distance within Generic WINNER Channel Model

Starting from the premise that stochastic properties of a radio environment can be abstracted by defining scenarios, a generic MIMO channel model is built by the WINNER project. The parameter space of the WINNER model is, among others, described by normal probability distributions and correlation coefficients that provide a suitable space for scenario comparison. The possibility to quantify the distance between reference scenarios and measurements enables objective comparison and classification of measurements into scenario classes. In this paper we approximate the WINNER scenarios with multivariate normal distributions and then use the mean Kullback-Leibler divergence to quantify their divergence. The results show that the WINNER scenario groups (A, B, C, and D) or propagation classes (LoS, OLoS, and NLoS) do not necessarily ensure minimum separation within the groups/classes. Instead, the following grouping minimizes intragroup distances: (i) indoor-to-outdoor and outdoor-to-indoor scenarios (A2, B4, and C4), (ii) macrocell configurations for suburban, urban, and rural scenarios (C1, C2, and D1), and (iii) indoor/hotspot/microcellular scenarios (A1, B3, and B1). The computation of the divergence between Ilmenau and Dresden measurements and WINNER scenarios confirms that the parameters of the C2 scenario are a proper reference for a large variety of urban macrocell environments.

Estimating the Output Gap to Support the Management of Interest Rates in Vietnam

In this paper, I apply three methods to estimate the output gap for Vietnam to support the conduct of monetary policy of the State Bank: the Hodrick-Prescott Filter, the production function approach and Bayesian estimation. I then compare the results obtained from these approaches and discuss their advantages and disadvantages to choose the optimal method for the estimation of the output gap for the State Bank of Vietnam. For the Bayesian approach, my paper closedly relies on the paper of Tim Willems (2011) with some modifications to fit the situation of Vietnam. The output gap estimated by Bayesian method appears to be the most consistent with the economic developments of Vietnam.
A brief review of the "vulgaris" lesions of the skin

Medical students and the trainees in dermatology and pathology have a curiosity about the names, such as, acne vulgaris or verruca vulgaris. The word “vulgaris” sounds like vulgar, commonly meaning crudely indecent, coarse, or obscene. However, the word “vulgar” is derived from the Latin word “vulgaris”, meaning “of or belonging to the common people”. In medical terminology, the word “vulgaris” means common or ordinary. A search through the indexes in Dermatology and Pathology text books revealed seven dermatologic conditions with “vulgaris” in their names. These included very common diseases, such as, acne vulgaris and verruca vulgaris as well as now rarely diagnosed disease, such as, lupus vulgaris. We are briefly reviewing the seven “vulgaris” diseases of the skin.
The Variability of Arctic Sea Ice Extent from Spring to Summer and Its Linkage to the Decline of SIE in September

The satellite record analysis for monthly differences of Arctic sea ice extent (SIE) shows that the most significant accelerated monthly sea ice reduction occurred between June and July although, on average, the largest sea ice reduction occurred between July and August. The monthly difference of June minus July (JJ) SIE has the strongest correlation with September SIE, with a correlation coefficient of −0.786 (original time series) and −0.625 (detrended time series) at confidence level of 99%. Furthermore, it is found that the correlation coefficient between JJ SIE and July minus August (JA) SIE is so low (0.068) that they can be thought to be independent from each other, considering that the JA SIE is also significantly negatively correlated to September SIE. A simple regression forecasting model for September SIE was established using monthly SIE differences for the JJ and JA. This study also shows that the JJ SIE is significantly correlated not only with sea level pressure (SLP) in polar regions and midlatitudes over eastern Atlantic in July, a pattern which resembles the negative phase of North Atlantic Oscillation (NAO), but also with sea surface temperature (SST) in midlatitudes over central North Pacific in the preceding spring.
The Generalized Filter Trading Rule under Time Varying Volatility

s Filter trading rule is a technical trading strategy with a long history dated back to the pioneer work by Alexander (1961). The filter trading rule generates a sequence of buy/sell trading signals according to the following principle. If the asset price moves up at least 100δ% from a low, the signal sequence will start with a buy signal. The rule then suggests to buy and hold the asset until the price moves down at least 100δ% from a subsequent high, at which time a sell signal is generated and the rule will suggest to sell and go short. It is interesting to observe that there is a mathematical equivalence between filter rule and the CUSUM technical control charts. CUSUM chart which is dated back even earlier to Page (1954) was proved to be Wald’s sequential probability ratio test (SPRT) and the assumption for its derivation is that the observations are independent. However, in financial markets, various kinds of dependencies of the asset’s returns have been long discovered and widely adopted. This paper is aiming to generalize the ordinary filter trading rule to cater for conditional heteroskedasticity.

Site-specific temporal and spatial validation of a generic plant pest forecast system with observations of Bactrocera dorsalis (oriental fruit fly)

This study introduces a simple generic model, the Generic Pest Forecast System (GPFS), for simulating the relative populations of non-indigenous arthropod pests in space and time. The model was designed to calculate the population index or relative population using hourly weather data as influenced by de velopmental rate, high and low temperature mortalities and wet soil moisture mortality. Each module contains biological parameters derived from controlled experiments. The hourly weather data used for the model inputs were obtained from the National Center of Environmental Prediction Climate Forecast System Reanalysis (NCEP-CFSR) at a 38 km spatial resolution. A combination of spatial and site-specific temporal data was used to validate the GPFS models. The oriental fruit fly, Bactrocera dorsalis (Hendel), was selected as a case study for this research because it is climatically driven and a major pest of fruit production. Results from the GPFS model were compared with field B. dorsalis survey data in three locations: 1) Bangalore, India; 2) Hawaii, USA; and 3) Wuhan, China. The GPFS captured the initial outbreaks and major population peaks of B. dorsalis reasonably well, although agreement varied between sites. An index of agreement test indicated that GPFS model simulations matched with field B. dorsalis observation data with a range between 0.50 and 0.94 (1.0 as a perfect match). Of the three locations, Wuhan showed
Evaluation of aluminium tolerance in grapevine rootstocks

Aluminum (Al) toxicity is a major worldwide agricultural problem. At low pH, Al speciates into the soluble and phyto-toxic form Al 3+ , inhibiting the root growth and affecting plant development. In Brazil, agriculture in acidic soils with elevated concentration of Al has significantly increased in the last decades. Therefore, in order to achieve efficient agriculture practices, the selection of plant cultivars with improved Al resistance has become crucial in this type of soils. In this work we have evaluated the Al resistance of six genotypes of grapevine rootstocks. The grapevine hardwood cuttings were grown in nutrient solution in the absence and presence of 250 and 500 μM Al at pH 4.2. The phenotypic indexes of relative root growth, fresh and dry root weight, root area, hematoxylin staining profile, and Al content were evaluated for all six genotypes. These phenotypic indexes allowed us to identify the 'Kober 5BB', 'Gravesac', 'Paulsen 1103', and 'IAC 766' grapevine rootstocks genotypes as the ones with the highest resistance to Al. Likewise, 'IAC 572' and 'R110 genotypes were the most Al-sensitive cultivars. We evaluated the root organic acid exudation profile in the most Al-resistant ('Kober 5BB') and most Al-sensitive ('R110') in plantlets cultivated in vitro in the absence and presence of 100, 200, and 400 μM of Al. Among several compounds detected, citrate was the only organic acid related to the Al resistance phenotype observed in the 'Kober 5BB' genotype. The high constitutive citrate exudation observed in 'Kober 5BB' strongly suggests that exudation of this particular organic acid may impart Al-resistance/amelioration in grapevine.
Human-Socialized Wolves Follow Diverse Human Gestures… And They May Not Be Alone.

Author(s): Udell, Monique A. R. ; Spencer, Jessica M. ; Dorey, Nicole R. ; Wynne, Clive D. L. | Abstract: Many studies document the domestic dogs’ responsiveness to human gestures. Reports of success on human guided tasks have led to evolutionary hypotheses that set dogs’ skills apart from other species, including other canids, in terms of their social cognition and comprehension of human communicative stimuli. However, until recently the range of other species tested and the availability of studies using equivalent testing methods between different species and groups have been limited, making it difficult to interpret cross-species comparisons. Here we demonstrate that human-socialized wolves are not only capable of responding to points made with the arm and hand, but are sensitive to a wide range of human gestures when given the opportunity to utilize such gestures in an object-choice task. Claims that domestic dogs are unique in their ability to respond to diverse novel stimuli may be in part due to the absence of data for the same range of gestures in other species. We also provide the first evidence that human-socialized coyotes have the capacity to utilize a human point to locate a target; further demonstrating that domestication is not a prerequisite for canid responsiveness to human actions, and that socialization and life experience are likely more important predictors of success
EFFECT OF END PLATE ON THE FLOW CROSSING A YAWED CIRCULAR CYLINDER

The uniform flow passing a yawed finite and infinite circular cylinder are numerically investigated in the regime of turbulent vortex street, the study of which is motivated by flow-induced vibration of tube bundle for helically coiled stream generators. The yaw angle of cylinder with flow direction varies from 0° to 45°, and the Reynolds number based on the diameter of cylinder and incoming velocity is taken as 3900. The turbulence behavior in the flow are calculated using Large Eddy Simulation and vortex is captured by Q-criterion. We thoroughly examined the flow behavior from the four flow characteristics, i.e. wake vortex structure, streamlines, pressure distribution, and Strouhal number. Our numerical results show that the end plates have a great effect on flow behavior, the wake by which is divided spanwise into three regions, two wall-end regions and the midspan region. In the midspan region, the so-called Independent Principle (IP) is held, which means the flow in this region is still with quasi-two dimension. However, the two wall-end regions exhibit strong different three-dimensional behavior, where the IP is broken down. The inclination of a cylinder induces the vortex concentrated in the downstream wall-end and thus strong shear layer are formed in the downstream wall-end plate.
Semantic Classification of Tatar Verbs : Selecting Relevant Parameters

This paper describes the methodology and current results of the ongoing classification of the Tatar lexicon in the process of developing databases of semantic classes of verbs. Our previous work included a semantic classification of Tatar verbs according to their basic meaning and thematic class. As a result, there have distinguished 59 basic semantic classes, with a semantic tag, or a set of tags, attributed to each of 3,200 verbs. If the thematic classification is universal and may be applied to any language, the currently developed classification described in this paper is based on the parametric principle and includes a set of morphological, syntactic, semantic, and derivational characteristics that are relevant for Tatar grammatical and semantic systems. In a sense, the work is aimed at creating a Tatar analogue of B. Levin’s verb classes, taking into account language-specific features. In the database, each semantic class, or subclass, is supposed to be provided with a set of admissible diathesis alternations and syntactic descriptions, depicting the verb valency, thematic roles of the arguments and semantic restrictions on them. By now we have created a detailed classification of speech, behavior, sound emissions, weather, emotions, mental states and actions verbs; when selecting the pertinent parameters and verifying their relevance, verbs of other classes were also considered.
Biochemical pathways for the production of flavour compounds in cheeses during ripening: A review

The principal pathways for the formation of flavour compounds in cheese (glycolysis, lipolysis and proteolysis) are reviewed. Depending on variety, microflora and ripening conditions, lac- tate may be metabolized by a number of pathways to various compounds which contribute to cheese flavour or off-flavours. Citrate metabolism by citrate-positive lactococci or Leuconostoc spp. is important in certain varieties (e.g., Dutch cheeses). Lipolysis results directly in the formation of flavour compounds by liberating free fatty acids (FFA). FFA may also be metabolized to alkan-2-ones and fatty acid lactones. Proteolysis of the caseins to a range of small- and intermediate-sized peptides and free amino acids (FAA) probably only contributes to the background flavour of most cheese varieties, but FAA are important precursors for a range of poorly-understood catabolic reactions which produce volatile compounds essential for flavour.
MESOSCALE PROCESSES INVOLVED IN FASTEX SECONDARY CYCLONES

The Fronts and Atlantic Storm-Track EXperiment (FASTEX, Joly et al. (1997)) took place during January and February 1997. This experiment allows for the first time to document secondary cyclogenesis at several scales thanks to an important experimental design. Indeed several aircraft carrying dual-beam Doppler radars, microphysical in-situ sensors and launching dropsonde were involved. As shown by Bouniol et al. (1999) or Lemaître et al. (1999) the combination of these measurements allows to document the mesoscale either in precipitating areas or in clear air region, the synoptic scale environment being described thanks to large scale ECMWF analyses. Thanks to this important data set, two majors ambitions had to be addressed: to evaluate hypotheses deduced from the recent theoretical studies of the dynamics of frontal cyclones. to document the dynamic of secondary lows in their mature stage at all scales of motions. In the past ten years numerical studies managed to reproduce the life cycle of secondary cyclones involving different processes, such as: upper and low level coupling processes (see for instance Thorncroft and Hoskins (1990)). low forcing of the large scale environment (see for instance Bishop and Thorpe (1994a, b)). conditional symmetric instability (see for instance Balasubramian and Yau (1994)). microphysical processes. Studies have also concentrated on the derivation of conceptual schemes of secondary cyclones from local observations (see for instance Browning (1997)). In this context this paper aims at: summarizing the three dimensional dynamical and thermodynamical structure of a typical secondary cyclone and comparing the obtained image with the previously mentioned conceptual scheme. diagnosing the processes involved in the development of this typical secondary low. estimating the degree of generality of the previous results by scrutinizing another FASTEX case which has experienced an explosive deepening. ___________________________________________ * Corresponding author address: Dominique Bouniol, CETP/CNRS, 10/12 avenue de l'Europe, 78140 Vélizy, France; e-mail: Dominique.BOUNIOL@cetp.ipsl. fr 2 SELECTED CASES
