DFIG-based WECS fault ride through complying with Australian grid codes

Doubly Fed Induction Generators (DFIGs) are widely used in variable speed wind turbine owing to its superior advantages that include ability to extract more energy from turbine, capability to control active and reactive power independently and the use of reduced converter rating that reduces its overall cost. On the other side fluctuating output power, weak fault ride through capability and high sensitivity to grid disturbances are the main issues that affect DFIG performance. In this paper, superconducting magnetic energy storage (SMES) unit is proposed to improve the fault ride through (FRT) capability of DFIG-based wind energy conversion system (WECS) during voltage sag and voltage swell events in the grid side. A new control approach for SMES unit using hysteresis current controller (HCC) along with proportional integral (PI) controller is introduced. Australian grid codes are used to examine the capability of the proposed controller to improve the FRT of the DFIG and hence maintaining the wind turbine connection to the grid during studied faults. Simulations results show the effectiveness of the SMES controller in maintaining system parameters within safety margins that comply with the Australian grid codes.
The Biology of Traditions: Food for thought: social learning about food in feeding capuchin monkeys

Introduction It used to be thought that shared behaviors are learned from others and that this was especially true of infants and their mothers. In recent years, many scientists have advocated parsimony in interpreting the diffusion of innovative behaviors in primates (Galef, 1991; Heyes and Galef, 1996; Lefebvre, 1995; Miklosi, 1999; Tomasello and Call, 1997; Visalberghi and Fragaszy, 1990a). This view has prompted systematic investigations of the learning processes involved in the spread of innovations and fueled debates on the nature of cultural traditions (Boesch and Tomasello, 1998; Whiten et al., 1999). Capuchin monkeys are among the few primate species in which systematic research has been carried out on the acquisition and social learning of tool-using skills (Anderson, 2000; Fragaszy and Visalberghi, 1989; Visalberghi, 1993), on the patterns of object-related and goal-directed behaviors (Custance, Whiten, and Fredman, 1999; Fragaszy, Vitale, and Ritchie, 1994), and on the patterns of food-processing behaviors (e.g., “food washing”) (Visalberghi and Fragaszy, 1990b; for an extensive review see Visalberghi and Fragaszy, 2002). Overall, these studies have demonstrated that social influences such as stimulus enhancement, local enhancement, and object reenactment are indeed present, whereas imitative learning (defined as learning a novel behavior by observing it performed by a demonstrator) is not (Visalberghi, 2000; Visalberghi and Fragaszy, 2002). Therefore, although the species name Cebus imitator assigned to capuchin monkeys by the prominent taxonomist Thomas (1903) seems unwarranted, we have begun to realize that other social learning processes seem to influence capuchins' behavior.
Entity recognition and resolution in semi-structured data

Potentially usable business information exists in unstructured form. This information, although machine readable, resides in unstructured human language texts that are difficult to process by computers. Within this information are references to real world entities, which are the focus of this paper. More specifically, we address the recognition of references to entities and their resolution, in the context of semi-structured data. This kind of data is structured according to a model which defines only generic semantics for its data elements, or includes data elements that contain natural language text. Semi-structured data presents new challenges and opportunities. In this kind of data, grammatical evidence is very often insufficient for entity recognition, since short sentences and simple expressions are predominant. However, the contextual information given by the structure of the data opens new possibilities for innovative techniques. We propose an approach to integrating the support for structured data throughout the complete process. It will be evaluated by studying three entity types in two scenarios with different semi-structured data formats, each one with distinct characteristics.
Bcl-2 correlates with localization but not outcome in human osteosarcoma

bcl-2 is a member of the bcl-2 family that inhibits apoptosis, plays a crucial role in cell viability and is expressed in various types of tumors. With respect to inconsistent results in previous studies, the aim of the present study was to generate a clear hypothesis with regards to the value of bcl-2 expression as a predictive or prognostic factor in human osteosarcoma. The expression of bcl-2 was examined immunohistochemically in 49 patients with high-grade osteosarcoma and the results were correlated with localization, histological response to chemotherapy, survival and the occurrence of metastases. In patients with osteosarcoma, 21/49 cases (43%) were positive for bcl-2 expression and the remaining cases were negative. A significantly higher expression of bcl-2 was observed in central tumors located in the pelvis (83 vs. 37% positive; P<0.05). The bcl-2 expression status revealed no statistically significant correlation with response to chemotherapy, with 57% of patients with bcl-2-positive tumors showing a good response and 43% showing a poor response. No significant difference was observed when comparing survival or occurrence in bcl-2-positive and -negative tumors. In conclusion, the results of the present study indicate that, despite higher bcl-2 expression in central osteosarcoma, the expression in high-grade osteosarcoma is not a reliable prognostic or predictive marker.
The crossover of work engagement between working couples : a closer look at the role of empathy

Purpose – The purpose of this paper is to examine the role of empathy (empathic concern and perspective taking) in the crossover process. Specifically, it aims to test whether empathy moderates the crossover effect of women's work engagement to their men's work engagement. Additionally, it seeks to investigate the relationship between men's engagement and colleague ratings of job performance.Design/methodology/approach – Hypotheses were tested using a cross‐sectional design with three sources of information: 175 Dutch women and their partners working in different occupational sectors, as well as 175 colleagues of the male participants.Findings – Results of moderated structural equation modeling analyses showed that the crossover of work engagement from women to men was strongest when men were high (vs low) in perspective taking (the spontaneous tendency of a person to adopt the psychological perspective of other people). Empathic concern did not moderate the crossover effect. In addition, men's work engag.
Quantitative analysis of vesicle recycling at the calyx of Held synapse

Significance Compared with vesicle exocytosis and endocytosis, relatively little is known about vesicle recycling. Here, we developed a novel methodological approach, potentially applicable to all axosomatic synapses, to quantify the kinetics of vesicle recycling with exquisite signal and temporal resolution. Using this approach combined with electron-microscopic observations, we estimated that ∼80% of synaptic vesicles participate in recycling and provided an explanation to reconcile the discrepancies in previous reports. We kinetically dissected vesicle recycling in the calyceal terminal, defined a new concept of the readily priming pool, and proposed a realistic kinetic model to quantify the basic properties of vesicle recycling. These findings contribute to filling the gap in understanding vesicle recycling, particularly postendocytotic vesicle trafficking. Vesicle recycling is pivotal for maintaining reliable synaptic signaling, but its basic properties remain poorly understood. Here, we developed an approach to quantitatively analyze the kinetics of vesicle recycling with exquisite signal and temporal resolution at the calyx of Held synapse. The combination of this electrophysiological approach with electron microscopy revealed that ∼80% of vesicles (∼270,000 out of ∼330,000) in the nerve terminal are involved in recycling. Under sustained stimulation, recycled vesicles start to be reused in tens of seconds when ∼47% of the preserved vesicles in the recycling pool (RP) are depleted. The heterogeneity of vesicle recycling as well as two kinetic components of RP depletion revealed the existence of a replenishable pool of vesicles before the priming stage and led to a realistic kinetic model that assesses the size of the subpools of the RP. Thus, our study quantified the kinetics of vesicle recycling and kinetically dissected the whole vesicle pool in the calyceal terminal into the readily releasable pool (∼0.6%), the readily priming pool (∼46%), the premature pool (∼33%), and the resting pool (∼20%).
Using content addressable techniques to optimize client-server systems

Efficient access to bulk data over the Internet has become a critical problem in today's world. Even while bandwidth, both in the core and the edge of the network, is improving, the simultaneous growth in the use of digital media and large personal data sets is placing increasing demands on it. Further, with increasing trends towards mobility, an increasing amount of data access is over cellular and wireless networks. These trends are placing pressure on applications and the Wide-Area Network (WAN) to deliver better performance to the end user. This dissertation puts forward the claim that external resources can be used in an opportunistic manner to optimize bulk data transfer in WAN-based client-server systems. In particular, it advocates the use of content-addressable techniques, a system-independent method for naming objects, to cleanly enable these optimizations. By detecting similarity between different data sources, these techniques allow external sources to be used without weakening any attributes, including consistency, of legacy systems and with no or minor changes to the original system. This dissertation validates this claim empirically through the use of five case studies that encompass the two traditional forms of data storage, file systems and database systems, and then generalizes the claim in the form of a generic transfer service that can be shared by different applications. In each of these case studies, I focus on three questions. First, even with the addition of content-based optimizations, how does the resulting system still maintain the attributes and semantics of the original system? Second, how do these systems efficiently find similarity in data? Third, does the use of these content-addressable techniques provide a substantial performance improvement when compared to the original system? These questions are answered with a detailed description of the system design and implementation and a careful evaluation of the prototypes with both synthetic and real benchmarks.
Energy Calibration of the Pixels of Spectral X-ray Detectors

The energy information acquired using spectral X-ray detectors allows noninvasive identification and characterization of chemical components of a material. To achieve this, it is important that the energy response of the detector is calibrated. The established techniques for energy calibration are not practical for routine use in pre-clinical or clinical research environment. This is due to the requirements of using monochromatic radiation sources such as synchrotron, radio-isotopes, and prohibitively long time needed to set up the equipment and make measurements. To address these limitations, we have developed an automated technique for calibrating the energy response of the pixels in a spectral X-ray detector that runs with minimal user intervention. This technique uses the X-ray tube voltage (kVp) as a reference energy, which is stepped through an energy range of interest. This technique locates the energy threshold where a pixel transitions from not-counting (off) to counting (on). Similarly, we have developed a technique for calibrating the energy response of individual pixels using X-ray fluorescence generated by metallic targets directly irradiated with polychromatic X-rays, and additionally γ-rays from 241Am. This technique was used to measure the energy response of individual pixels in CdTe-Medipix3RX by characterizing noise performance, threshold dispersion, gain variation and spectral resolution. The comparison of these two techniques shows the energy difference of 1 keV at 59.5 keV which is less than the spectral resolution of the detector (full-width at half-maximum of 8 keV at 59.5 keV). Both techniques can be used as quality control tools in a pre-clinical multi-energy CT scanner using spectral X-ray detectors.
A multiple sub-models self-tuning control algorithm of non-uniformly sampled systems based on auxiliary-variable-model

For the control issue of non-uniformly sampled data systems, a novel control scheme is proposed by using multiple sub-models. The input-output relationship model is obtained by using mathematical analysis and derivation for a class of multi-rates systems non-uniformly sampled from their continuous-time systems. For unmeasurable information vectors arising in the identification model, an auxiliary-model-based gradient descent identification algorithm is used to estimate the model parameters of the non-uniformly sampled systems. Next, we present a new self-tuning control scheme based on designing the controllers of multiple sub-models. Finally, the simulation example is studied to demonstrate the effectiveness of the proposed method.
Congruences of the Partition Function

Let p(n) denote the partition function. In this article, we will show that congruences of the formexist for all primes m and l satisfying m≥13 and l≠2,3,m, where B is a suitably chosen integer depending on m and l. Here, the integer k depends on the Hecke eigenvalues of a certain invariant subspace of S m/2−1 (Γ 0 (576),χ 12 ) and can be explicitly computed.More generally, we will show that for each integer i>0 there exists an integer k such that with a properly chosen B the congruenceholds for all integers n not divisible by l.
Measurement of endotracheal tube cuff pressure: Instrumental versus conventional method

Objective: To evaluate the conventional practice of endotracheal tube (ETT) cuff inflation and pressure measurement as compared to the instrumental method. Study Design: Prospective observational study. Place and Duration of Study: Department of Anaesthesia, King Saud University Hospital, Riyadh, Saudi Arabia (June 2014–July 2014). Methods: A total of 100 adult patients were observed according to the syringe size used Group-1 (10 ml) and Group-2 (20 ml) for ETT cuff inflation in general anesthesia. Patients with anticipated difficult intubation, risk for aspiration, known anatomical laryngotracheal abnormalities, and emergency cases were excluded. Trachea was intubated with size 8 or 8.5 mm and 7.0 or 7.5 mm ETT in male and female patients respectively. The ETT cuff was inflated with air by one of the anesthesia technician. Cuff pressures were measured using aneroid manometer. ETT cuff pressure of 20–30 cm of water was considered as standard. Results: In 69% of the patients, the cuff pressure measurements were above the standard. Age (P = 0.806), weight (P = 0.527), height (P = 0.850), and gender (P = 1.00) were comparable in both groups. The mean cuff pressure in Group-1 and Group-2 was 32.52 ± 6.39 and 38.90 ± 6.60 cm of water (P = 0.001). The cuff inflation with 20 ml syringe resulted in higher cuff pressure as compared to 10cc syringe 37.73 ± 4.23 versus 40.74 ± 5.01 (86% vs. 52%, P = 0.013). Conclusion: The conventional method for ETT cuff inflation and pressure measuring is unreliable. As a routine instrumental cuff pressure, monitoring is suggested.
Viral Gastroenteritis Outbreaks in Europe, 1995–2000

To gain understanding of surveillance and epidemiology of viral gastroenteritis outbreaks in Europe, we compiled data from 10 surveillance systems in the Foodborne Viruses in Europe network. Established surveillance systems found Norovirus to be responsible for >85% (N=3,714) of all nonbacterial outbreaks of gastroenteritis reported from 1995 to 2000. However, the absolute number and population-based rates of viral gastroenteritis outbreaks differed markedly among European surveillance systems. A wide range of estimates of the importance of foodborne transmission were also found. We review these differences within the context of the sources of outbreak surveillance information, clinical definitions, and structures of the outbreak surveillance systems.
Energy and F0 contour modeling with functional data analysis for emotional speech detection

This paper proposes the use of reference models to detect emotional prominence in the energy and F0 contours. The proposed framework aims to model the intrinsic variability of these prosodic features. We present a novel approach based on Functional Data Analysis (FDA) to build reference models using a family of energy and F0 contours, which are implemented with lexicon-independent models. The neutral models are represented by bases of functions and the testing energy and F0 contours are characterized by their projections onto the corresponding bases. The proposed system can lead to accuracies as high as 80.4% in binary emotion classification in the EMODB corpus, which is 17.6% higher than the one achieved by a benchmark classifier trained with sentence level prosodic features. The approach is also evaluated with the SEMAINE corpus, showing that it can be effectively used in real applications. Index Terms: Emotion detection, prosody modeling, emotional speech analysis, expressive speech, functional data analysis.
A Distributed Algorithm for Workflow Recovery

Even though the automatic recovery techniques of workflow have attracted enough attention in recent years, several critical issues regarding the distributed recovery have not been addressed. For example, if we do the recovery under sustained attacks, in which condition the recovery can terminate? Is a synchronized clock necessary for distributed recovery? In this paper, we proposed a dead-lock free attack recovery algorithm for coordinated recovery and answered related questions. We defined different IDS report orders, and discussed the termination of the recovery under the given IDS report orders. We also proved that under specific situations, we have to freeze the recovery scheme to guarantee that the recovery can make progress.
DISCRIMINATION OF RESIDENT AND INFILTRATED ALVEOLAR MACROPHAGES BY FLOW CYTOMETRY IN INFLUENZA A VIRUS-INFECTED MICE

Laser flow cytometric analysis was used in conjunction with in vivo labeling with the lipophilic fluorescent dye DiIC18(5)-DS to discriminate resident alveolar macrophages from newly infiltrating monocytes/macrophages in mice with and without pulmonary influenza A virus infection. Leukocytes in bronchoalveolar lavage (BAL) and peripheral blood were analyzed by 2-color flow cytometry as a function of time following intravenous injection of DiIC18(5)-DS. At 4 hours, dye-positive leukocytes were present in both BAL and blood of normal mice, indicating that DiIC18(5)-DS rapidly crossed the pulmonary endothelial-epithelial barrier. At 4 days after dye injection, 98% of BAL cells were DiIC18(5)-DS positive, and almost all of these were monocytes/macrophages based on labeling with fluorescein isothiocyanate (FITC)-conjugated antibody to the Mac-3 marker. Only 3.2% ± 0.3% of peripheral blood monocytes (∼0.16% of total peripheral blood leukocytes) were DiIC18(5)-DS positive at 6 days after injection, whereas >95% of BAL leukocytes were strongly dye-positive on days 6 to 28. When DiIC18(5)-DS was injected in mice 6 days prior to intranasal challenge with influenza A, flow cytometry indicated that 57.8% ± 5.6% and 60.7% ± 8.5% of macrophages/monocytes in BAL were newly infiltrated (i.e., DiIC18(5)-DS negative, Mac-3 positive) at 4 and 7 days, respectively, post viral infection. The discrimination of subpopulations of resident and newly recruited macrophages in BAL should facilitate future mechanistic studies on pulmonary infection and inflammatory lung injury.

The experts debate: Perioperative beta-blockade for noncardiac surgery—proven safe or not?

Guidelines on perioperative management of patients undergoing noncardiac surgery recommend the use of prophylactic perioperative beta-blockers in high-risk patients who are not already taking them, and their continuance in patients on chronic beta-blockade prior to surgery. These recommendations were challenged recently by results of the Perioperative Ischemic Evaluation (POISE), a large randomized trial of extended-release metoprolol succinate started immediately before noncardiac surgery in patients at high risk for atherosclerotic disease. While metoprolol significantly reduced myocardial infarctions relative to placebo in POISE, it also was associated with significant excesses of both stroke and mortality. The merits and limitations of POISE and its applicability in light of other trials of perioperative beta-blockade are debated here by two experts in the field—Dr. Don Poldermans and Dr. P. J. Devereaux (co-principal investigator of POISE).
Engineered FADD Induces Apoptosis via an Artificial Death-Inducing Signaling Complex (DISC)

An engineered Fas-associated death domain protein (FADD), 2DEDplusE—made previously by fusing the tandem DEDs of FADD to the E protein of lambda phage-greatly enhances apoptosis-inducing activity in adherent cells in vitro. To investigate the mechanism of apoptosis-inducing activity of this engineered FADD, we compared the apoptosis-inducing activity of various other engineered FADDs. The tandem DED of 2DEDplusE contributed most to the enhancement of apoptosis, and the E protein contributed moderately. The engineered factor produced artificial death-inducing signaling complex (DISC)-like signals in the cytoplasm that appear as grains under fluorescence microscopy. Membrane blebbing associated with apoptosis was observed just after formation of grain-like signals. Immunoprecipitation analysis demonstrated that 2DEDplusE-FLAG can bind p43/p41 forms of caspase 8 but E protein-FLAG cannot. Gel filtration analysis demonstrated that 2DEDplusE forms a large complex containing partially cleaved procaspase 8 (p43/p41) in the cytoplasm; the size of this complex varies greatly. In the absence of an extrinsic signal, the engineered FADD formed artificial DISC in the cytoplasm, and then its tandem DED activated procaspase 8, which in turn executed apoptosis. The engineered FADD complex closely mimicked intrinsic DISC and increased apoptosis-inducing activity.
