Spatiotemporal EEG Source Localization using ECDs during Smooth Pursuit Eye Movement

A linear moving white full circle on a CRT display was presented to subjects. Moving patterns were downward, upward, to the right and left. Subjects were requested to trace the stimulus. Meantime, electroencephalograms (EEG) were recorded. The EEG was summed in each movement and the equivalent current dipole localization (ECDL) was done to estimate the source in the brain. As results, the dipoles were localized to the V5 at latency of approximately 143ms, and after to the intraparietal sulcus (IPS, 162ms), to precentral gyrus (PrCG, 224ms) to the frontal eye field (FEF, 236ms) and to the superior colliculus (SC, 248ms). The direction of estimated dipole corresponded with the opposite movements. And the dipole to the superior colliculus was estimated, this organ is supposed to correspond with the eye movement. Also a dorsal pathway and a ventral pathway were found.
Updating a public procurement maturity model: the case of the MSU+ model

Public procurement maturity in the Netherlands is commonly measured with the MSU+ model, but public organizations tend to score low in this model. Critics mention the low visibility of possible improvements in the assessment, reflected in the manner of presentation of assessment results. As MSU+ was agreed on as a measuring tool for Dutch Government organizations, it is desired to improve the model. Therefore, the purpose of this research is to identify the exact problems and possible solutions to increase the relevance and applicability of MSU+ for the Dutch public sector. A design science approach was enacted for this explorative research. The research model, based on Hevner (2004), guided the execution of a relevance, rigor and design cycle to derive at perceived problems and respective design propositions. Findings reveal that experts do not perceive the need to change the structure of the MSU+ model. Recommendations are formulated for the presentation of assessment results and for clarifying certain parts of strategic and enabling processes. Moreover, new public sector developments as sustainability, social return, best value procurement and the new Dutch procurement law should not be included more specifically in the model in order to ensure applicability across the whole public sector. This research adds to existing literature by setting direction on what to do with new public sector developments and concepts when updating procurement maturity models. In addition, public procurement maturity measurement is still in its infancy with not many applied models around the world yet, leaving the possibility of MSU+ being applied in other countries.
Microfoundations of Routines and Capabilities: Individuals, Processes, and Structure

This article introduces the Special Issue and discusses the microfoundations of routines and capabilities, including why a microfoundations view is needed and how it may inform work on organizational and competitive heterogeneity. Building on extant research, we identify three primary categories of micro‐level components underlying routines and capabilities: individuals, social processes, and structure. We discuss how these components, and their interactions, may affect routines and capabilities. In doing so, we outline a research agenda for advancing the field's understanding of the microfoundations of routines and capabilities.
Accommodating Two Worlds in One Organization: Changing Board Models in Agricultural Cooperatives

While most economic organisation literature on cooperatives has focused on changes in income rights, we study changes in the allocation of decision rights between board of directors (representing members) and managers. The traditional role of the board is to direct the activities of the managers. However, professional management increasingly makes most strategic decisions, pushing the board into a supervisory role. We present two groups of findings on changing board – management relationships. We identify three corporate governance models: traditional model, management model, and corporation model, and we present an empirical illustration showing a relationship between the choice of board model and product portfolio and performance.
Lipid and volatile composition of Borage (Borago officinalis L.) leaf

Lipid and volatile composition of Borago officinalis L. leaf was investigated. The results showed that α-linolenic acid was the major fatty acid followed by stearidonic acid. Total lipids were composed of neutral and polar lipids. Polar lipids were mainly composed of phosphatidylcholine as the major phospholipid, whereas monogalactosyldiacylglycerol was the major galactolipid. Quant to neutral lipids, they were mainly composed of triacylglycerols. The volatile composition exhibited the presence of many green note compounds such as hexanal, (E)-2-hexenal, hexanol, (Z)-3-hexenol, (E)-2-hexenol and nonanol. Borage leaf appears to be an important source of essential fatty acids, phospholipids, glycolipids and green note volatile compounds for food, cosmetic, pharmaceutical and biomedical applications.
A Smart Thermo-hygrometric Global Index for the Evaluation of Particularly Critical Urban Areas Quality: the City of Messina Chosen as a Case Study

The development of the city, as it has grown up to the present day, is no longer sustainable. The design of the city turns toward smart urban development which achieves the theoretical ideal of an environmental sustainability deeply linked to the well-being of the inhabitants. In this perspective, the idea of comfort is related to the achievement of thermohygrometric conditions satisfaction (both indoor and outdoor). The present work proposes an innovative tool evaluating the external environment quality applied to a case study: the Messina's urban center. The well-being has been investigated from the point of view of temperature and relative humidity, taking not into account other aspects characterizing quality of the urban environment such as traffic, degree of urbanization, air pollution, etc. For this reason the overall hygrothermal index formulation results of particular interest: this one can be also used to make comparable various results obtained at international level. One of the key properties of the global index is the comparability of the results, when applied to different realities. Such an important property can be exploited to compare the climatic characteristics of different cities and for different areas of the same city. In fact, with the help of multiple monitoring stations within the urban area, you would be able to detect the so-called heat islands. In this way it is possible constructing a map of the hygrometric comfort suitable to achieve better urban planning (for example improving thermal comfort through the construction of green areas).

In order to diagnose the ecological health status of rivers in cold area more scientifically, This paper analyzes the characteristics of rivers in cold regions, and references the relevant literature to diagnose the health status of rivers according to the characteristics of river health by using the analytic hierarchy process and the fuzzy comprehensive method. Select the HunheShen Fu period as a case, determine the weight of each index and the status quo. The diagnosis results show that the river health level of Shenhe section of Hunhe River is in a sick state, and the main influencing factors are water quality and hydrological indexes. Based on this, the suggestions of river rehabilitation are put forward.
Gender Differences in the Alteration of Obesogenic Environments in Korean Children According to GNB3 Polymorphism

Background: A single-nucleotide polymorphism, C825T in the G protein β3 subunit (GNB3) gene, is associated with essential hypertension and obesity. However, the potential interaction of the GNB3C825T polymorphism with obesogenic environmentsin obesity of Korean children has not been closely evaluated yet. Methods: We analyzed data collected from 635 boys and 627 girls aged 8-9 yearsrecruited from seven elementary schools in Seoul, South Korea. Measures of anthropometry and blood pressure (BP) as well as fasting blood samples were used in the analysis. Three-day food records were collected. Results: Obese children had higher BP, lipid profiles and insulinresistance-related factors than did lean children. Higher body mass index (BMI), waist circumference (WC)and BP and lowerplasma lipid profiles were observed in boys than in girls. The genotype frequencies of the GNB3 polymorphism were CC=23.7%, CT=52.1%, and TT=24.2%, and the allele frequencies were C allele=49.7% and T allele=50.3 in the subjects. There was no significant difference according to gender and obesity with allelic frequencies. Boys with the T allele were more obese thanthose with the C allele, but the C and T alleles, according to anthropometrics and plasma variables, did not differ between the obesity and lean groups. In contrast to boys, obese girls with the T allele had lower BMI and WC than those with the C allele, although they had higher plasma cholesteroland energy intakes compared to those with the C allele. We found that the HDL3c subtype, fasting insulin and homeostasis model assessment of insulin resistance decreased with increasing HDL peak amount, which was positively correlated with total HDLcholesterol. However, the HDL subtypes were not changed by the GNB3 C825T polymorphism. Conclusion: The GNB3 C825T polymorphism influences the childhood obesity rate and energy intakesdifferentially by gender in Korean children.
Performance Enhancement of an Image Retrieval by Integrat- ing Text and Visual Features I Najimun Nisha S, II Mehar Ban K.A

An image retrieval system is a computer system for browsing, searching and retrieving images from a huge database of digital images. Most traditional and ordinary methods of image retrieval use some method of adding metadata such as captioning', keywords, or descriptions to the images so that retrieval can be performed over the annotation words. Manual image annotation is time-consuming, laborious and expensive; to address this, there has been a large amount of research done on automatic image annotation. There are two types of image retrieval such as text-based image retrieval and content-based image retrieval. Content-based image retrieval (CBIR) – the application of computer vision to the image retrieval. CBIR aims at avoiding the use of textual descriptions and instead retrieves images based on similarities in their contents (textures, colors, shapes etc.) to a user-supplied query image or user-specified image features. Both techniques individually have both advantages and disadvantages. In our work, a vertical search engine is proposed to improve image retrieval performance by integrating text and visual features. It is implemented as vertical product search engine for apparels shopping by discovering relationship between textual features and image features. User intention gap and semantic gap is bridged by integrating textual and visual features. Visual features are reweighted according to their significance to the query terms. Hence, precision and recall of content based image retrieval is improved.
TREHALOSE CAN IMPROVE PLATELET AGGREGATION VERSUS COLLAGEN AGONIST DURING LYOPHILIZED PLATELET PREPARATION

Due to short shelf life of platelet concentrate 3-5 days, long-term preservation of human platelets will greatly reduce the risk of their shortage. Lyophilization has been proved feasible approach for this purpose. We want to show that platelets can be preserved by freeze-drying them with loading buffer containing trehalose, a sugar found at high concentrations in organisms that naturally survive drying. Washed platelet samples in a concentration of 0.8-1x10 9 plt/mL in loading buffers containing trehalose at various concentrations were incubated at 37°C for 4 h. Platelets were lyophilized with optimized concentration of trehalose 40 mmol/L. The aggregation response of trehalose-loaded platelets was tested against collagen agonist (2.0 µg/ml). Our results showed that aggregation of PRP, resuspended platelet samples in loading buffers containing 10, 20, 30 and 40 mmol/L trehalose and rehydrated lyophilized platelet containing 40 mmol/L trehalose were measured versus collagen agonist by aggregometry instrument with the activity of 7.7%, 22.3%, 45.9%, 71.4% and 35.3% respectively. However, when the platelets lyophilized without trehalose, most of the platelets disintegrated during rehydration step, some fused with adjacent cells and formed an insoluble clump. We concluded that trehalose at the concentration of 40 mmol/L can improve platelet aggregation activity versus collagen agonist in the loading buffer or dried state. Keywords: Trehalose; collagen; lyophilized platelet; platelet aggregation
Optical Bandpass Filter Design Using Split Ring Resonators

Bandpass filter design using metallic split ring resonators (SRR) at optical frequencies is theoretically investigated in this paper. The transmission and reflection coefficients and the transmission phase of SRR array will be analyzed. We will show that there are many magnitude peaks in transmission coefficient that can be used as bandpass filter in 1550 nm-band. Increasing the number of SRR layers will cause increase in the number of magnitude peaks and narrowing of the bandwidth. The numerical analysis is performed using the transfer matrix method (TMM).
Bandwidth selection for kernel density estimation with length-biased data

ABSTRACT Length-biased data are a particular case of weighted data, which arise in many situations: biomedicine, quality control or epidemiology among others. In this paper we study the theoretical properties of kernel density estimation in the context of length-biased data, proposing two consistent bootstrap methods that we use for bandwidth selection. Apart from the bootstrap bandwidth selectors we suggest a rule-of-thumb. These bandwidth selection proposals are compared with a least-squares cross-validation method. A simulation study is accomplished to understand the behaviour of the procedures in finite samples.
A newmethod for the numerical analysis of thermoluminescence glow curve

A new method to analyze the thermoluminescence (TL) glow curve has been presented. It has been shown that this method is efficient and fast in generating the TL glow curves and can be adopted in a numerical curve fitting for obtaining the relevant TL parameters of a given TL glow curve data. This new method is based on a general approximation (GA) which assumes only that the concentration of the electrons in the conduction band is negligible when compared with the concentration of the electrons in the traps. The GA method has been tested against the reference glow curve data which was generated by the full iteration method without any prior approximation in the one-trap-onerecombination-centre model. By finding the best fit between the reference data and the curves generated by the GA method, the values of the kinetics parameters have been determined. Also, the general order kinetics (GOK) and the peak shape method have been examined. The fitted values of the activation energy and the initial concentration of electron by the GA method match reasonably well with the original value. © 2007 Elsevier Ltd. All rights reserved.

Performance Analysis of an Offshore Gas-Turbine Power System

The objective of this paper is to analyze the dynamic performance of an offshore gas-turbine power system operating in normal and abnormal situations. The system primarily consisted of two gas-turbine generation systems and other electrical components. The mathematical models for the components, developed to cater for the dynamic behavior of the system using Simulink and SimPowerSystems, included gas-turbine model, electric machine model, electromechanical model, and three-phase power transformer model. The method for predicting the dynamic responses of interconnected machine systems, named dynamic voltage-current combination method, was employed to connect system components in this research. Simulation results show that the system operated satisfactorily in normal and abnormal conditions. The dynamic behavior study for an offshore power system is essential for system planning, operation, and further expansion.
Functional analysis for the development of bio-medical products

The engineer nowadays needs to possess knowledge that will enable the design of more diverse and cheaper products, but of higher quality, which reach the market faster, and do not pollute. These requirements are the effect of globalization, competition, reduction of the life-cycle of a product, managing the environmental issues, increasing computing power related to communication networks etc. The present paper proposes research applying technical functional analysis for the development of a surgical device manufactured from biocompatible silicone rubber. The vacuum surgical device is a treatment instrument for skin ulcers resistant to antibiotics and difficult to treat because of other connected diseases. The product is fabricated by open mould casting in a selective laser sintered (additive manufactured) mould, obtained after performing functional analysis. Functional analysis is applied to establish the optimum mould concept and the technological process of manufacturing it. Additive manufacturing is used for both the intermediary functional prototype production of the mould and the zero series mould.
Photon Counting Linear Discriminant Analysis with Integral Imaging for Occluded Target Recognition

This paper discusses a photon-counting linear discriminant analysis (LDA) with computational integral imaging (II). The computational II method reconstructs three-dimensional (3D) objects on the reconstruction planes located at arbitrary depth-levels. A maximum likelihood estimation (MLE) can be used to estimate the Poisson parameters of photon counts in the reconstruction space. The photon-counting LDA combined with the computational II method is developed in order to classify partially occluded objects with photon-limited images. Unknown targets are classified with the estimated Poisson parameters while reconstructed irradiance images are trained. It is shown that a low number of photons are sufficient to classify occluded objects with the proposed method.
Effects of an aqueous extract of Azadirachta indica on the growth of larvae and development of pupae of Culex quinquefasciatus.

The neem tree Azadirachta indica Juss (Meliaceae) is one of the most studied plant species for pest control, including mosquitoes. However, the effect of aqueous neem seed extracts (ANSE) on each of the 4 instars of mosquito Culex quinquefasciatus Say (Diptera: Culicidae) is unknown. In order to determine the effect of applying ANSE on the growth of each of the 4 larval instars and pupal stage of C. quinquefasciatus , 8 bioassays with ANSE concentrations ranging from 30 to 1000 ppm were applied to larvae of 1st, 2nd, 3rd and 4th instars. The experimental unit consisted of a plastic cup with 100 ml of water and 20 larvae. 1 ml of the different concentrations of ANSE was applied. Mortality was assessed when 93 to 98% of the larvae reached the pupae stage in the control. In the surviving population the duration of larval stages and pupae viability were recorded. The growth of larvae and development of pupae was recorded to determine a growth inhibition index (GII) and a relative growth index (RGI), which was used to calculate the EC
Distribution of sympatric seahorse species along a gradient of habitat complexity in a seagrass-dominated community

We present estimates of local population abundance, distribution and habitat prefer- ence for 2 European seahorse species, Hippocampus guttulatus and H. hippocampus. We predicted that these sympatric species would partition their habitat into 2 broadly defined habitat types: com- plex vegetated habitats and sparsely vegetated sand flats. We sampled populations using underwa- ter visual census techniques over landscape (100s to 1000s m) and microhabitat scales (<1 m). Over landscape scales, we estimated abundance and quantified habitat associations using generalized linear models. Over microhabitat scales, we tested for holdfast (attachment site) preferences using selection indices. Both species were patchy in distribution, but H. guttulatus mean density (0.073 ind. m -2 ) was one order of magnitude greater than that of H. hippocampus (0.007 ind. m -2 ). At a landscape scale, H. guttulatus abundance was positively correlated with an index of habitat com- plexity, the percentage of substrate covered by flora and sessile fauna. Conversely, H. hippocampus used more open and less speciose habitats that were subjected to greater oceanic influences. At microhabitat scales, both species significantly preferred grasping holdfasts over barren surfaces, but the species differed in holdfast preferences: H. guttulatus grasped all prospective holdfast types with equal probability while H. hippocampus significantly avoided both fauna and flora that formed large colonies or tracts of dense vegetation. Patterns in habitat use were consistent with differences in morphology and foraging strategy. Despite similar life histories, these sympatric species may respond differently to disturbances that modify habitat structure and complexity over landscape or micro- habitat scales.
Molecular and cellular mechanisms of acute cytotoxic liver damage as potential biological targets for magnesium-containing cell-protective drug

Introduction. Many anti-tumor drugs have a high potential for toxic damage to liver cells, which makes it necessary to identify molecular mechanisms of the development of the negative impact of drugs on the liver and to develop effective methods for preventing and correcting this adverse effect. Materials and methods. The study was performed on 30 nonlinear white rats of both sexes weighing 180–220 g, divided into 3 equal groups (n = 10 in each): intact control, control with liver pathology and experimental group of rats receiving the test substance LBK-527 at a dose of 100 mg/kg/day intragastrically one hour before the administration of a hepatoxic cytarabine. In the animals of the latter two groups, acute drug-induced hepatitis was simulated by intravenous administration of 2 g/m2 cytarabine in physiological saline for 5 days. Liver pathomorphology was studied on specimens stained with hematoxylin and eosin, Sudan III and by Van Gieson; a semi-quantitative method for assessing the depth of inflammatory and dystrophic organ damage was used. In the blood plasma, the activity of ASAT, ALAT, GGTP, and APF was determined. Tissue concentrations of TNF-alpha, IL-10 and HGF were determined by quantitative ELISA. Expression of Bcl-2 and Ki-67 was studied by immunohistochemistry. The proliferation index was calculated. Results and discussion. Daily administration of LBK-527 for 5 days restrains the depth of cytarabine-induced pathomorphological changes in the liver, reduces the prevalence of the dystrophic and inflammatory process, increases the anti-inflammatory and regenerative potential of the hepatic parenchyma, inhibits the programmed death of hepatocytes and reduces the activity of cytolytic and cholestatic syndromes. Conclusion. Magnesium-containing cell-protective substance LBK-527 protects liver from cytarabine-induced injury.
