Distribución factible de aerogeneradores en un parque eólico.

El articulo propone una metodologia para la distribucion de turbinas en un emplazamiento priorizado en la Provincia de Pichincha en Ecuador, basado en mapas obtenidos de un analisis multicriterio. El emplazamiento se caracteriza por espacios llanos, de baja densidad de aire y alto recurso eolico. El poligono priorizado del sitio se lo realizo analizando el mapa de vientos y multicriterio, los mismos que son mapas tipo raster y tienen una resolucion de 200x200 metros, este es el punto de partida para la ubicacion de aerogeneradores. Previo al procesamiento y tratamiento de datos, se analizo las metodologias utilizadas en estudios anteriores para optimizar la ubicacion de las turbina en diferentes tipos de emplazamiento. La metodologia propuesta para la distribucion de turbinas eolicas en el emplazamiento, considera la direccion predominante del viento para la creacion de un tensor que contiene la posicion de los aerogeneradores en un poligono, con el fin de simular el efecto estela. Se obtuvieron varias distribuciones para la instalacion de aerogeneradores, cada una de ellas con su respectivo numero de turbinas y capacidad instalable. Por ultimo, se determino que la capacidad maxima instalable en el poligono priorizado utilizando la metodologia propuesta es de 98MW con 49 aerogeneradores de 2MW.

Language Model and Clustering based Information Retrieval

In this paper, we describe two novel frameworks for improving search results. Both of them organize relevant documents into clusters utilizing a new soft clustering method and language models. The first framework is query-independent and takes into account only the inter-document lexical or semantic similarities in order to form clusters. Also, we try to locate the duplicated content inside the formed clusters. The second framework is query-dependent and uses a query expansion technique for the cluster formation. The experimental evaluation demonstrates that the proposed method performs well in the majority of the results.
On the relationship between autistic traits and executive functioning in a non-clinical Dutch student population

We examined the association between autistic traits and different aspects of executive functioning (EF), using non-clinical Social Science and Science students as participants. Autistic traits, and associated personality traits, were measured using the Autism Quotient (AQ) and the Temperament and Character Inventory (TCI), respectively. EF was examined by means of a random number generation test and a phonemic fluency test. Using appropriate dependent measures, the following EF components were examined: 1) inhibition of prepotent responding, 2) simple output inhibition, 3) working memory monitoring and updating, and 4) switching. No significant relationship was found between the AQ and each of the four components of EF. However, two TCI subscales were reliably correlated with either the working memory or the shifting component. These results were discussed in view of the concept of an autism spectrum with respect to executive abilities.
Audience Management Practices of Live Streamers on Twitch

Live streaming is a unique medium that merges different layers of communication by facilitating individual, group, and mass communication simultaneously. Streamers who broadcast themselves on live streaming platforms such as Twitch are their own media entity and have the challenge of having to manage interactions with many different types of online audiences beyond the translucent platform interfaces. Through qualitative interviews with 25 Twitch streamers, in this paper we share streamers’ practices of discovering audience composition, categorizing audience groups, and developing appropriate mechanisms to interact with them despite geographical, technological, and temporal limitations. We discuss streamers’ appropriation of real-time signals provided by these platforms as sources of information, and their dependence on both technology and voluntary human labor to scale their media entity. We conclude with design recommendations for streaming platforms to provide streamer-centric tools for audience management, especially for knowledge discovery and growth management.
Structural and functional dichotomy of human midcingulate cortex

Anterior cingulate cortex is comprised of perigenual and midcingulate regions based on cytology, imaging and connections. Its anterior (aMCC) and posterior (pMCC) parts and transition to posterior area 23 were evaluated in six human cingulate gyri with Nissl staining and immunoreactions for neuron‐specific nuclear binding protein and intermediate neurofilament proteins (NFP), and their pain and emotion functions evaluated in standard coordinates. Morphological differences included a poorly differentiated layer III with few NFP‐expressing neurons in aMCC and a very dense layer Va with small and large pyramids intermingled in pMCC. The density of NFP‐positive, layer Vb neurons was higher in pMCC than in aMCC. The junction of pMCC with area 23 had a dysgranular area 23d with clumps of layer IV neurons and a very dense layer Va. Each case was co‐registered to standard coordinates and the regional borders identified and measured. Although both regions had overall equivalent activations during noxious cutaneous thermal stimulation, the posterior two‐thirds of pMCC was relatively inactive. About 60% of fear‐induced activity was in aMCC, sadness and happiness activated perigenual cortex, and neither were activated with non‐emotion tasks. Thus, pain activity is coupled to fear in aMCC, while other MCC processing is not related to affect. Beyond midcingulate duality, this is the first report of a very dense layer Va for areas p24′ and 23 and the features of transitional area 23d. The MCC dichotomy suggests that two circuits differentially regulate the two cingulate motor areas, and involvement of aMCC in pain and fear make it selectively vulnerable to chronic pain and stress syndromes.
The polymeric immunoglobulin receptor is the major calmodulin‐binding protein in an endosome fraction from rat liver enriched in recycling receptors

Rat liver endosomes contain one major high‐affinity calmodulin‐binding protein (CaMBP) that now has been identified as the polymeric immunoglobulin receptor (pIgR). In isolated endosomes pIgR was enriched in the receptor‐recycling compartment (RRC); lesser enrichment was found in ‘early’ endosome (CURL) and much less in ‘late’ endosome fractions (multivesicular bodies, MVB). The distribution of the major CaMBP, shown by Western blotting or by overlay with I125‐calmodulin in the isolated fractions, was consistent with rapid accumulation of I125‐immunoglobulin A (IgA) in RRC and CURL after intravenous injection into rats. The receptor was also found in sinusoidal plasma membranes but not in cell fractions containing apical (bile canalicular) or lateral plasma membrane domains of the hepatocyte. The interaction of pIgR with calmodulin was shown by direct binding assays and by affinity chromatography. Thus, calmodulin is the first cytoplasmic protein shown to interact with the pIgR. We postulate that calmodulin regulates pIgA trafficking in rat liver. In addition, the receptor recycling fraction emerges as an endosomal subcompartment involved in pIgA transport via pIgR.
Translation Errors and Incomprehensibility: a Case Study using Machine-Translated Second Language Proficiency Tests

This paper reports on an experiment where 795 human participants answered to the questions taken from second language proficiency tests that were translated to their native language. The output of three machine translation systems and two different human translations were used as the test material. We classified the translation errors in the questions according to an error taxonomy and analyzed the participants’ response on the basis of the type and frequency of the translation errors. Through the analysis, we identified several types of errors that deteriorated most the accuracy of the participants’ answers, their confidence on the answers, and their overall evaluation of the translation quality.
Metyrapone administration reduces the strength of an emotional memory trace in a long-lasting manner.

CONTEXT It has recently been demonstrated that the process of memory retrieval serves as a reactivation mechanism whereby the memory trace that is reactivated during retrieval is once again sensitive to modifications by environmental or pharmacological manipulations. Recent studies have shown that glucocorticoids (GCs) have the capacity to modulate the process of memory retrieval. This suggests that GCs could be an interesting avenue to investigate with regard to reduction of emotional memory. OBJECTIVE The current study assessed whether a pharmacological decrease in GC levels, induced by metyrapone, a potent inhibitor of GC secretion, would affect retrieval of emotional and neutral information in an acute and/or long-lasting manner. DESIGN, SETTING, PARTICIPANTS, AND INTERVENTION To do so, 1 × 750 mg dose of metyrapone, 2 × 750 mg dose of metyrapone, or placebo was administered to young normal participants 3 d after the encoding of a slide show having neutral and emotional segments. The experiment took place in a university and a hospital setting. MAIN OUTCOME MEASURE Memory performance was assessed after treatment and 4 d later. RESULTS RESULTS showed that retrieval of emotional information was acutely impaired in the double-dose metyrapone group and that this effect was still present 4 d later, when GC levels were not different between groups. CONCLUSIONS These results show that decreasing GC levels via metyrapone administration is an efficient way to reduce the strength of an emotional memory in a long-lasting manner.
Auditory Event-Related Potentials and Psychological Changes during Sleep Deprivation

This study investigated the psychophysiological effects of sleep deprivation on auditory event-related potentials (AERPs) and their relationship with psychological parameters. Twenty-four subjects remained awake for 37 h under continuous surveillance. In the mornings and the evenings of 2 consecutive study days, AERPs were recorded and 4 self-rated scales (sleepiness, fatigue, anxiety, and mood) were quantified. The latencies of P300 and N200 were significantly prolonged (p < 0.001) and their amplitudes decreased (p < 0.05) as a consequence of sleep deprivation. However, the only significant change in N100 and P200 was an increase in the P200 amplitude (p < 0.05). The increase in the latencies of P300 and N200 were correlated with increased sleepiness (p < 0.05), and the increase in P200 amplitude was correlated with negative mood, anxiety, and fatigue (p < 0.05). Although the changes in P300 and N200 induced by sleep deprivation are due to sleepiness, which may slow cognitive processing and decrease the efficiency of mental processing, the increase in P200 may be related with increased anxiety, negative mood, and fatigue.
Atmospheric monitoring with a spectrographic imager

A compact airborne spectrographic imager (CASI) mounted on top of an attitude stabilizing platform inside a Cessna 207T was used to monitor changes in and around a lake near Berlin for 4 months in 1993-1994. The radiance was recorded at three different altitudes in the wavelength range 0.4-0.9 mu m. The observed radiances were found to be different from 1 month to another due to the variability of phytoplankton and suspended solids in the lake. The observed radiance was similar when measured at three different altitudes during the same month, whereas the effect of altitude was seen when comparing the radiances from month to month. The radiances in the month of May 1994 have been found to be anomalous when comparing the radiances measured at the altitudes 1500 and 2000 m in the months of July and September 1993 and February 1994. This anomaly was found to be associated with aerosol concentration around an altitude of 1500-2000 m in the atmosphere as compared with LOWTRAN modelling.
An efficient regularized neighborhood discriminant analysis through QR decomposition

Inspired by the concept of manifold learning, the discriminant embedding technologies aim to exploit low dimensional discriminant manifold structure in the high dimensional space for dimension reduction and classification. However, such graph embedding framework based techniques usually suffer from the large complexity and small sample size (SSS) problem. To address the problem, we reformulate the Laplacian matrix and propose a regularized neighborhood discriminant analysis method, namely RNDA, to discover the local discriminant information, which follows similar approach to regularized LDA. Compared with other discriminant embedding techniques, RNDA achieves efficiency by employing the QR decomposition as a pre-step. Experiments on face databases are presented to show the outstanding performance of the proposed method.
Lower tacrolimus daily dose requirements and acute rejection rates in the CYP3A5 nonexpressers than expressers

Background CYP3A5 genetic polymorphisms contribute to marked interindividual differences in the metabolism of and response to tacrolimus in humans. Objective This study was aimed to clarify the impact of the CYP3A5*3 variant on tacrolimus dose requirements and acute rejection rates in patients with organ transplantation. Methods A literature search was performed up to August 2009 by using the Cochrane library, PubMed, Medline, and EMBase. Results Twenty-three studies (a total of 1779 patients) were included in this meta-analysis. Eighteen studies (1443 patients) were involved in renal transplantation and five studies (336 patients) in liver transplantation. Results of meta-analysis demonstrated that, in renal transplant patients, despite the presence of significant heterogeneity, CYP3A5 expressers required higher mean tacrolimus daily doses by 0.045 mg/kg (95% confidence interval (CI), 0.033–0.056) than nonexpressers. Furthermore, sub-analysis of the time of posttransplantation showed that CYP3A5 expressers required higher daily doses than nonexpressers by 0.010, 0.084, 0.041, 0.037, and 0.044 mg/kg at week 2, and at month 1, 3, 6, and 12, respectively. Subset analysis of the ethnicity of organ recipients indicated that mean tacrolimus daily doses were 0.056, 0.037, and 0.077 mg/kg higher in CYP3A5 expressers than non- expressers for white, Chinese, and Japanese patients, respectively. In contrast, for liver transplant patients, higher tacrolimus daily doses were required not only in CYP3A5 expressers of the organ donors than nonexpressers by 0.024 mg/kg (95% CI, 0.019–0.028), but also in CYP3A5 expresser of the organ recipients than nonexpresser by 0.012 mg/kg (95% CI, 0.005–0.018). However, a significant difference in the acute organ rejection rate was observed only at one month (odds ratio, 3.27; 95% CI, 1.57–6.81; P=0.002). Conclusion Tacrolimus daily dose requirements may vary with the presence of the CYP3A5*3 variant, ethnicity of the organ recipients, and the time of posttransplantation. In addition, the acute organ rejection rate may be higher in CYP3A5 expressers than nonexpressers over the first month after transplantation.
Modelling the Integrated QoS for Wireless Sensor Networks with Heterogeneous Data Traffic

The future of Internet of Things (IoT) is envisaged to consist of a high amount of wireless resource-constrained devices connected to the Internet. Moreover, a lot of novel real-world services offered by IoT devices are realized by wireless sensor networks (WSNs). Integrating WSN to the Internet has therefore brought forward the requirements of an end-to-end quality of service (QoS) guarantee. In this paper, the QoS requirements for the WSN-Internet integration are investigated by first distinguishing the Internet QoS from the WSN QoS. Next, this study emphasizes on WSN applications that involve traffic with different levels of importance, thus the way realtime traffic and delay-tolerant traffic are handled to guarantee QoS in the network is studied. Additionally, an overview of the integration strategies is given, and the delay-tolerant network (DTN) gateway, being one of the desirable approaches for integrating WSNs to the Internet, is discussed. Next, the implementation of the service model is presented, by considering both traffic prioritization and service differentiation. Based on the simulation results in OPNET Modeler, it is observed that real-time traffic achieve low bound delay while delay-tolerant traffic experience a lower packet dropped, hence indicating that the needs of real-time and delay-tolerant traffic can be better met by treating both packet types differently. Furthermore, a vehicular network is used as an example case to describe the applicability of the framework in a real IoT application environment, followed by a discussion on the future work of this research.
Primary percutaneous coronary intervention vs conservative treatment for acute ST elevation myocardial infarction: short- and long-term follow-up according to disease severity.

BACKGROUND Because there is insufficient evidence to support primary percutaneous coronary intervention (PPCI) as the treatment of acute myocardial infarction (AMI), this study elucidated the efficacy of PPCI according to disease severity. METHODS AND RESULTS Between January 1999 and June 2001, 3,021 AMI patients were registered at Tokyo Women's Medical University and 17 affiliated institutions. Of these, 1,994 patients with ST-elevation AMI were admitted within 12 h of onset. PPCI was performed in 1,143 and 294 were treated conservatively. The 1,437 patients were grouped according to Thrombolysis In Myocardial Infarction-risk score: PPCI was performed in 59.5% of the low-risk group, 61.8% of the moderate-risk group, and 56.2% of the high-risk group. Cardiac death was the primary outcome. In the low-risk group, no significant differences were observed between PPCI and conservative therapy for 30-day and long-term cardiac mortality rates. In the moderate-risk group, the 30-day cardiac mortality rate for PPCI was significantly lower; however, no significant intergroup differences were observed for long-term cardiac mortality. In the high-risk group, 30-day and long-term cardiac mortality for PPCI were significantly more favourable than for conservative therapy (p<0.001 and p=0.0032, respectively). CONCLUSIONS Although PPCI strongly correlated with low short- and long-term cardiac mortality rates in high-risk AMI patients, no similar correlation was found in low-risk patients.
Same‐sex behavior, sexually transmitted diseases and HIV risks among young northern Thai men

Objectives: To assess the risks for HIV infection and sexually transmitted diseases (STD) among young northern Thai men who have sex with men (MSM), and to examine the possible role of male same‐sex behavior in the northern Thai HIV/AIDS epidemic. Methods: Two cohorts of northern Thai military conscripts and one cohort of recently discharged conscripts, a total of 2047 men, were studied. Data were collected by interview on behavioral risk factors, and sera were examined for syphilis and HIV‐1 antibodies. Univariate and multiple logistic regression analyses were used to determine risk factors associated with HIV and STD, and to assess the frequency and patterns of same‐sex behaviors among these men. Results: Of 2047 men, 134 (6.5%) reported one or more male lifetime sex partners. Of these MSM, 130 (97.0%) also had female partners, and four (3.0%) had exclusively male partners. Compared with men who reported only female sex partners, MSM had a higher number of lifetime sex partners, a higher mean number of female sex partners, more female and male commercial sex worker (CSW) partners, and were more likely to be married. MSM were significantly more likely than exclusively heterosexual men to report having had any STD [odds ratio (OR), 2.72], gonorrhea (OR, 2.05), syphilis (OR, 3.17), non‐gonococcal urethritis (OR, 4.54) and penile discharges (OR, 6.24). They were at borderline increased risk for HIV infection [OR, 1.51; 95% confidence interval (Cl), 0.95‐2.41]. Men with more than one lifetime male sex partner compared with those with only one partner were significantly more likely to be HIV‐infected (OR, 2.81; 95% Cl, 1.09‐7.19). Conclusions: Northern Thai MSM are a high‐risk population for STD, including HIV. Reported same‐sex behavior in this population appears to vary considerably with data collection techniques. HIV and STD prevention strategies aimed at changing unsafe sexual practices may need to be targeted to the general population of young Thai men.
Biodiversity in a changing climate: a synthesis of current and projected trends in the US

This paper provides a synthesis of the recent literature describing how global biodiversity is being affected by climate change and is projected to respond in the future. Current studies reinforce earlier findings of major climate-change-related impacts on biological systems and document new, more subtle after-effects. For example, many species are shifting their distributions and phenologies at faster rates than were recorded just a few years ago; however, responses are not uniform across species. Shifts have been idiosyncratic and in some cases counterintuitive, promoting new community compositions and altering biotic interactions. Although genetic diversity enhances species' potential to respond to variable conditions, climate change may outpace intrinsic adaptive capacities and increase the relative vulnerabilities of many organisms. Developing effective adaptation strategies for biodiversity conservation will not only require flexible decision-making and management approaches that account for uncerta.
A simple method for combining probability distribution functions relevant to radar and communications systems

We provide a mathematical proof that the convolution or “faltung” method of adding probability distributions is equivalent to the characteristic function method that is widely accepted by mathematicians and described in almost all texts on probability and statistics. We further show by a simple example that the convolution method provides a much simpler approach to the combination of distributions and actually enables the computation of these combinations that would have been very difficult, if not impossible, using the characteristic function approach.
Comparison of end-tidal and transcutaneous measures of carbon dioxide during general anaesthesia in severely obese adults.

BACKGROUND Patients with severe obesity (body mass index (BMI) greater than 35 kg x m(-2)) present difficulties for end-tidal carbon dioxide (FE'(CO(2))) monitoring. Previous studies suggest that transcutaneous (TC) carbon dioxide measurements could be valuable, so we compared FE' and TC measures with Pa(CO(2)) in severely obese patients during anaesthesia. METHODS We studied patients with severe obesity (BMI >or=40 kg x m(-2)) undergoing gastric bypass surgery. Carbon dioxide was measured with both FE' and TC devices. The difference between each measure (FE'(CO(2)) and TC-CO(2)) and the Pa(CO(2)) was averaged for each patient to provide one value, and data compared with a non-paired, two-way t-test, Fisher's exact test. RESULTS We studied 30 adults (aged 18-54 yr, mean 41, SD 8.0 yr; weight: 115-267 kg, mean 162, SD 35 kg). The absolute difference between the TC-CO(2) and Pa(CO(2)) was 0.2 (0.2) (mean, SD) kPa while the absolute difference between the FE'(CO(2)) and Pa(CO(2)) was 0.7 (0.4) kPa (P<0.0001). The bias and precision were +0.1 (0.3) kPa for TC vs arterial carbon dioxide and -0.7 (0.4) kPa for FE' vs arterial carbon dioxide. CONCLUSIONS Transcutaneous carbon dioxide monitoring provides a better estimate of Pa(CO(2)) than FE'(CO(2)) in patients with severe obesity.
