Analyzing natural human language from the point of view of dynamic of a complex network
Venue: Expert Syst. Appl.

We present complex network model for semantic representation of human language.Contextual scope from texts are inferred from physical measures in complex networks.The complex network modeled presents behavior of scale free networks.Human language has modular characteristic in the relationship between words.The relationship between words of human language is a sparse space. With increasing amount of information, mainly due to the explosive growth of Internet, the demand for applications of automatic text analysis has also grown. One of the tools that has increased in importance in the understanding of problems related to this area are complex networks. This tool merges graph theory and statistical methods for modeling important problems. In several research fields, complex networks are studied from the various points of view, such as: topology of networks, extraction of physical features and statistics, specific applications, comparison of metrics and study of physical phenomena. Linguistic is one area that has received great attention, particularly due to its close relationship with issues arising from the emergence of large text databases. Thus, many studies have emerged for modeling of complex networks in this area, increasing the demand for efficient algorithms for feature extraction, network dynamic observation and comparison of behavior for different types of languages. Some works for specific languages such as English, Chinese, French, Spanish, Russian and Arabic, have discussed the semantic aspects of these languages. On the other hand, as an important feature of a network we can highlight the computation of average clustering coefficient. This measure has a physical impact on the network topology studies and consequently on the conclusions about the semantics of a language. However its computational time is of O(n3) making its computing prohibitive for large current databases. This paper presents as main contribution a modeling of two complex networks: the first one, in English, is constructed from a specific medical database; the second, in Portuguese, from a journalistic manually annotated database. Our paper then presents the study of the dynamics of these two networks. We show their small world behavior and the influence of hubs, suggesting that these databases have a high degree of Modularity, indicating specific contexts of words. Also, a method for efficient clustering coefficient computation is presented, and can be applied to large current databases. Other features such as fraction of reciprocal connections and average connection density are also calculated and discussed for both networks.
Contextual design solutions with an Emphasis on Humanistic context;Case study: Historical Context of Langerud

Designing in historical contexts has a special importance because of its value and coordination. These days we can see constructions in the historical contexts which have not desirable interaction with the context because of inattention to the relationship between building and its context and this is a destructive factor. The harm is visible visually and in dealing with nature and climate of the region. Langerud is not an exception. Some parts of the historic context of the city has been turned into ruins and the river which this valuable context has been formed around it has lost its potential. So the place attachment of citizens to the historical context of their city has been decreased. In this regard we decided to provide instructions for designing in historical context and river margin of Langerud to avoid more damages. Applying these factors, in addition to linking the new building to the valuable historical context with the visual aspect, also can meet the needs of the day and more citizens and tourists will be attracted to the complex by development of sense of place. In this study research's method has a descriptive analytical approach. At first, result of researches about humanistic contextualism and identity of place were discussed by using library research method and then more precise researches on contextualism in Langerud's historical context were done by using field method (observation and interviews) At the end the special designing provisions of this region was presented which can be named as this research's consequences.
Room temperature gas sensing properties of ultrathin carbon nanotube films by surfactant free dip coating

Large scale production of reliable carbon nanotubes (CNTs) based gas sensors involves the development of scalable and reliable processes for the fabrication of films with controlled morphology. Here, we report for the first time on highly scalable, ultrathin CNT films, to be employed as conductometric sensors for NO2 and NH3 detection at room temperature. The sensing films are produced by dip coating using dissolved CNTs in chlorosulfonic acid as a working solution. This surfactant free approach does not require any post treatment for the removal of dispersants or any CNTs functionalization, thus promising high quality CNTs for better sensitivity and low production costs. The effect of CNT film thickness and defect density on the gas sensing properties has been investigated. Detection limits of 1 ppm for NO2 and 7 ppm for NH3 have been achieved at room temperature. The experimental results reveal that defect density and film thickness can be controlled to optimize the sensing response. Gas desorption has been accelerated by continuous in situ UV irradiation.
Surfactant control of gas transfer velocity along an offshore coastal transect: results from a laboratory gas exchange tank

Understanding the physical and biogeochemical controls of air sea gas exchange is necessary for establishing biogeochemical models for predicting regional and global scale trace gas fluxes and feedbacks. To this end we report the results of experiments designed to constrain the effect of surfactants in the sea surface microlayer (SML) on the gas transfer velocity (kw; cm h 1) seasonally (2012 2013) along a 20 km coastal transect (North East UK) We measured total surfactant activity (SA) chromophoric dissolved organic matter (CDOM) and chlorophyll a (Chl a) in the SML and in sub surface water (SSW) and we evaluated corresponding kw values using a custom designed air sea gas exchange tank. Temporal SA variability exceeded its spatial variability. Overall, SA varied 5 fold between all samples (0.08 to 0.38 mg L 1 T X 100) being highest in the SML during summer. SML SA enrichment factors (EFs) relative to SSW were 1.0 to 1.9, except for two values (0.75; 0.89: February 2013) The range in corresponding k660 (kw for CO2 in seawater at 20 degC) was 6.8 to 22.0 cm h 1. The film factor R660 (the ratio of k660 for seawater to k660 for "clean" i.e. surfactant free, laboratory water) was strongly correlated with SML SA (r 0.70, p 0.002, each n 16) High SML SA typically corresponded to k660 suppressions 14 to 51 relative to clean laboratory water, highlighting strong spatiotemporal gradients in gas exchange due to varying surfactant in these coastal waters. Such variability should be taken account of when evaluating marine trace gas sources and sinks. Total CDOM absorbance (250 to 450 nm) the CDOM spectral slope ratio (SR S275 295/S350 400) the 250 365 nm CDOM absorption ratio (E2 E3) and Chl a all indicated spatial and temporal signals in the quantity and composition of organic matter in the SML and SSW. This prompts us to hypothesise that spatiotemporal variation in R660 and its relationship with SA is a consequence of compositional differences in the surfactant fraction of the SML DOM pool that warrants further investigation.
ultraLM and miniLM: Locator tools for smart tracking of fluorescent cells in correlative light and electron microscopy
Venue: Wellcome open research

In resin fluorescence (IRF) protocols preserve fluorescent proteins in resin embedded cells and tissues for correlative light and electron microscopy, aiding interpretation of macromolecular function within the complex cellular landscape. Dual contrast IRF samples can be imaged in separate fluorescence and electron microscopes, or in dual modality integrated microscopes for high resolution correlation of fluorophore to organelle. IRF samples also offer a unique opportunity to automate correlative imaging workflows. Here we present two new locator tools for finding and following fluorescent cells in IRF blocks, enabling future automation of correlative imaging. The ultraLM is a fluorescence microscope that integrates with an ultramicrotome, which enables 'smart collection' of ultrathin sections containing fluorescent cells or tissues for subsequent transmission electron microscopy or array tomography. The miniLM is a fluorescence microscope that integrates with serial block face scanning electron microscopes, which enables 'smart tracking' of fluorescent structures during automated serial electron image acquisition from large cell and tissue volumes.
Indigenous Knowledge Approach to Successful Psychotherapies with Aboriginal Suicide Attempters
Venue: Canadian journal of psychiatry. Revue canadienne de psychiatrie

Suicide is disproportionately common among Aboriginal people in Canada.  Life stories were collected from 54 Aboriginal suicide attempters in northern Saskatchewan. Constant comparison techniques and modified grounded theory identified common themes expressed.  Three common plots/themes preceded suicide attempts: 1) relationship breakup, usually sudden, unanticipated, involving a third person; 2) being publicly humiliated by another person(s) accompanied by high levels of shame; and 3) high levels of unremitting, chronic life stress (including poverty) with relative isolation. We found 5 common purposes for suicide attempts: 1) to "show" someone how badly they had hurt the attempter, 2) to stop the pain, 3) to save face in a difficult social situation, 4) to get revenge, and 5) don't know/don't remember/made sense at the time, all stated by people who were under the influence of alcohol and/or drugs at the time of their suicide attempt. We found 5 common beliefs about death: 1) you just cease to exist, and everything just disappears; 2) you go into the spirit world and can see and hear everything that is happening in this world; 3) you go to heaven or hell; 4) you go to a better place; and 5) don't know/didn't think about it.  The idea of personal and cultural continuity is essential to understanding suicide among First Nations youth. Interventions targeted to the individual's beliefs about death, purpose for suicide, and consistent with the life story (plot) in which they find themselves may be more successful than one size fits all programs developed outside of aboriginal communities.

Venue: IECON 2016 42nd Annual Conference of the IEEE Industrial Electronics Society

This paper presents an FPGA based synthesizable offline UAV local path planner implementation using Evolutionary Algorithms for 3D unknown environments. A Genetic Algorithm is selected as the path planning algorithm and all units of it are executed on a single FPGA board. In this study, Nexys 4 Artix 7 FPGA board is selected as the target device and Xilinx Vivado 2015.4 software is used for synthesis and analysis of HDL design. Local path planner is designed in a way that it has two flight modes: free elevation flight mode and fixed elevation flight mode. Designed FPGA based local path planner which has 74 MHz operating frequency and 62% logic slice utilization is tested into two different unknown environments generated by a LIDAR sensor. Results show that both GAs are efficient path planning algorithms for UAV applications and FPGAs are very suitable platforms for flight planning periphery.
Path planner for UAVs navigation based on A* algorithm incorporating intersection
Venue: 2016 IEEE Chinese Guidance, Navigation and Control Conference (CGNCC)

A combination process of A* algorithm incorporating intersection is utilized to design a path planner for unmanned aerial vehicles (UAVs) autonomous navigation. The evaluation index of candidate path points is introduced in this method. It increases the consistency of the target direction and the search direction, and ensures the path towards the direction of the target point. In order to improve the security of the planned path, a path allocation method is designed. Under the same environment of simulation, the efficiency for the UAV path planning of this method is greater compared with the mixed algorithm of Dijkstra and Dijkstra PSO.
Gold Triangular Nanoprisms and Nanodecahedra: Synthesis and Interaction Studies with Luminol toward Biosensor Applications.
Venue: Langmuir the ACS journal of surfaces and colloids

Gold triangular nanoprisms and nanodecahedra (pentagonal bipyramids) were synthesized in the absence and presence of nanoseeds by a simple solvothermal synthesis through the reduction of Auric Chloride (HAuCl4) with poly(vinylpyrrolidone) (PVP) in N,N dimethylformamide (DMF) respectively. These gold nanoparticles exhibit two plasmon resonance bands. The interaction of these gold nanoparticles with luminol was investigated using UV vis and fluorescence spectroscopy since hefty number of environmental and biological sensors are based on the combination of luminol and gold nanoparticles. The gold nanoparticles quenches the fluorescence of luminol through a static quenching mechanism, i.e. ground state complex formation, which was confirmed by both absorption spectroscopy as well as time resolved fluorescence spectroscopy. The Stern Volmer quenching constant and the effective quenching constant determine that gold nanodecahedra has more interaction with luminol than that of triangular gold nanoprisms. The distance between the gold nanoparticles and luminol, calculated using FRET theory, is less than 8 nm, which indicates efficient energy transfer during interaction. These results are expected to be useful for the development of novel sensors.
Growth Blocking Peptides As Nutrition Sensitive Signals for Insulin Secretion and Body Size Regulation
Venue: PLoS biology

In Drosophila, the fat body, functionally equivalent to the mammalian liver and adipocytes, plays a central role in regulating systemic growth in response to nutrition. The fat body senses intracellular amino acids through Target of Rapamycin (TOR) signaling, and produces an unidentified humoral factor(s) to regulate insulin like peptide (ILP) synthesis and/or secretion in the insulin producing cells. Here, we find that two peptides, Growth Blocking Peptide (GBP1) and CG11395 (GBP2) are produced in the fat body in response to amino acids and TOR signaling. Reducing the expression of GBP1 and GBP2 (GBPs) specifically in the fat body results in smaller body size due to reduced growth rate. In addition, we found that GBPs stimulate ILP secretion from the insulin producing cells, either directly or indirectly, thereby increasing insulin and insulin like growth factor signaling activity throughout the body. Our findings fill an important gap in our understanding of how the fat body transmits nutritional information to the insulin producing cells to control body size.
Adaptive quality control and acceptance of pavement material density for intelligent road construction

During conventional road construction, quality control and acceptance (QC/QA) are based on limited spot tests of material density at random locations which may not be representative of the compacted area and may consist of potential bias. This research presented an innovative material machine information and human decision integrated system for adaptive QC/QA using the intelligent compaction (IC) technology to overcome the above limitation of conventional testing. In this integrated system, compaction properties such as material stiffness are monitored in real time with 100% coverage of compacted areas by instrumented IC rollers. By monitoring compaction process and roller ground interactions, this system can be used to determine compaction target values, which are in turn fed back to the IC system to optimize compaction efforts and improve construction quality. This approach can also be used to determine compaction uniformity for the as built in order to assess pavement performance. Recommended further development of the intelligent road construction technology is presented to fully leverage the IC technologies in the future.

On the construction of power quality control systems

Some aspects of the construction of power quality control systems in power supply systems are discussed. The basic requirements for quality factors of electric power are determined, the conditions of joint parallel operation of energy consumers are considered, and analysis of traditional ways of solving the emerging problems is carried out. The advantages and disadvantages of power quality control systems related to the capabilities of new technologies with application of high power semiconductor switching devices (GTO and IGCT thyristors, MOSFET and IGBT transistors) are considered. The application of computer technology in power quality control systems makes it possible to use rather complicated and effective algorithms of numerical processing of signals and significantly increase the accuracy of correction of disturbances in electric networks. The advantages and disadvantages of industrial plants constructed in the form of a controlled reactor with a dc magnetic bias and a reactor with a thyristor key are considered. Two types of devices to compensate for possible disadvantages are identified: devices using fully controlled keys and devices ones using artificial commutation and incompletely controlled power keys. A brief analysis of the known methods of electric power quality control is implemented. Recommendations for the establishment of power quality control systems are suggested in which the parameters of software depend on the solution algorithm of a posed problem, while the algorithm itself depends on the method of control and mathematical laws on which it is based. The method of control determines the structure of the power quality control system, while the software determines the basic operations of information processing, their quantity, the scheme of data processing, the volume data flows, etc.

Academic and licensure examination performances of BSN graduates Bases for curriculum enhancement

Author's Email: jdeleon@ceu.edu.ph Tel: +63 027362211. This study involved the correlation of academic performance and licensure examination results which were used as bases for curriculum enhancement. A descriptive correlational design was used to describe the academic performances, licensure examination, changes and perception of faculty in the curriculum and relationship of the academic and Nursing Licensure Examination (NLE) performances. Nursing graduates and faculty from the College of Nursing from chosen nursing schools were the respondents of the study. Mean and standard deviations were used to describe the academic performances and perceptions of faculty in the changes of the curriculum while Pearson's correlation was used in determining the relationship between academic and NLE performance in each of the 5 subjects. The results showed that academic performances are satisfactory in Nursing Care Management, Community Health Development and Research subjects. Nursing Licensure performances are also satisfactory however, graduates have difficulty passing examinations with Medical, Surgical and Psychiatry Nursing concepts. The academic performances in nursing professional subjects are related to nursing licensure performance. The changes in the curriculum brought additional subjects contents, units, hours and placement in the Bachelor of Science in Nursing (BSN) curriculum. Curriculum enhancement is necessary to improve academic and NLE performance of nursing graduates.
Procalcitonin in cerebrospinal fluid in meningitis: a prospective diagnostic study
Venue: Brain and behavior

Bacterial meningitis is a severe but treatable condition. Clinical symptoms may be ambiguous and current diagnostics lack sensitivity and specificity, complicating diagnosis. Procalcitonin (PCT) is a protein that is elevated in serum in bacterial infection. We aimed to assess the value of PCT in cerebrospinal fluid (CSF) in the diagnosis of bacterial meningitis.
Validation of a standard field test method in four countries to assess the toxicity of residues in dung of cattle treated with veterinary medical products.
Venue: Environmental toxicology and chemistry

Registration of veterinary medical products includes the provision that field tests may be required to assess potential nontarget effects associated with the excretion of product residues in dung of treated livestock (phase II, tier B testing) However, regulatory agencies provide no guidance on the format of these tests. In the present study, the authors report on the development of a standardized field test method designed to serve as a tier B test. Dung was collected from cattle before and up to 2 mo after treatment with a topical application of a test compound (ivermectin) Pats formed of dung from the different treatments were placed concurrently in the field to be colonized by insects. The abundance, richness, and diversity of insects developing from egg to adult in these pats were compared across treatments using analysis of variance tests. Regression analyses were used to regress abundance, richness, and diversity against residue concentrations in each treatment. Results of the regression were used to estimate mean lethal concentration (LC50) values. The robustness of the method and the repeatability of its findings were assessed concurrently in 4 countries (Canada, France, Switzerland, and The Netherlands) in climatically diverse ecoregions. Results were generally consistent across countries, and support the method's formal adoption by the European Union to assess the effects of veterinary medical product residues on the composition and diversity of insects in dung of treated livestock.
