Fault ride-through capability of doubly-fed induction generators based wind turbines

Current grid codes require DFIGs to provide voltage support during a grid fault. The fault ride-through (FRT) capability of DFIGs is the focus of this paper, in which modifications to the DFIG controller are proposed to improve the FRT capability. The static synchronous compensator (STATCOM) controller has been applied with the proposed method to study its influence on the voltage at the point of common coupling (PCC). The proposed method was also compared with other FRT capability improvement methods, including the conventional crowbar method. The dynamic behavior of DFIG-based wind turbines during grid fault is simulated using MATLAB/Simulink. The results obtained clearly demonstrate the efficacy of the proposed method.
A contribution to infinite disjoint covering systems

Supposons que la famille de suites arithmetiques {d i n+ b i : n ∈ Z} i ∈ I soit un recouvrement disjoint des nombres entiers. Nous prouvons qui si d i = p k q l pour des nombres premiers p,q et des entiers k,l > 0, il existe alors un j ¬= i tel que d i |d j . On conjecture que le resultat de divisibilite est vrai quelques soient les raisons d i . Un recouvrement disjoint est appele sature si la somme des inverses des raisons est egale a 1. La conjecture ci-dessus est vraie pour des recouvrements satures avec des d i dont le produit des facteurs premiers n'est pas superieur a 1254.
Spatial organization of precentral cortex in awake primates. II. Motor outputs.

Rapid rewind of a sound motion picture film in a sound motion picture camera or projector is facilitated by the use of a free-running sprocket wheel that is in engagement with the motion picture film on both sides of the sound transducer. During advancement of the film at normal speed, the sprocket wheel cooperates with a film tensioning device in maintaining the film in engagement with a rotary mechanical filter at the sound transducer. During rapid rewind, the tensioning device is released and the sprocket wheel helps to maintain the film spaced from the rotary mechanical filter.
Human Sarcoma Growth Is Sensitive to Small-Molecule Mediated AXIN Stabilization

Sarcomas are mesenchymal tumors showing high molecular heterogeneity, reflected at the histological level by the existence of more than fifty different subtypes. Genetic and epigenetic evidences link aberrant activation of the Wnt signaling to growth and progression of human sarcomas. This phenomenon, mainly accomplished by autocrine loop activity, is sustained by gene amplification, over-expression of Wnt ligands and co-receptors or epigenetic silencing of endogenous Wnt antagonists. We previously showed that pharmacological inhibition of Wnt signaling mediated by Axin stabilization produced in vitro and in vivo antitumor activity in glioblastoma tumors. Here, we report that targeting different sarcoma cell lines with the Wnt inhibitor/Axin stabilizer SEN461 produces a less transformed phenotype, as supported by modulation of anchorage-independent growth in vitro. At the molecular level, SEN461 treatment enhanced the stability of the scaffold protein Axin1, a key negative regulator of the Wnt signaling with tumor suppressor function, resulting in downstream effects coherent with inhibition of canonical Wnt signaling. Genetic phenocopy of small molecule Axin stabilization, through Axin1 over-expression, coherently resulted in strong impairment of soft-agar growth. Importantly, sarcoma growth inhibition through pharmacological Axin stabilization was also observed in a xenograft model in vivo in female CD-1 nude mice. Our findings suggest the usefulness of Wnt inhibitors with Axin stabilization activity as a potentialyl clinical relevant strategy for certain types of sarcomas.
Caloric Primary Rewards Systematically Alter Time Perception

Human time perception can be influenced by contextual factors, such as the presence of reward. Yet, the exact nature of the relationship between time perception and reward has not been conclusively characterized. We implemented a novel experimental paradigm to measure estimations of time across a range of suprasecond intervals, during the anticipation and after the consumption of fruit juice, a physiologically relevant primary reward. We show that average time estimations were systematically affected by the consumption of reward, but not by the anticipation of reward. Compared with baseline estimations of time, reward consumption was associated with subsequent overproductions of time, and this effect increased for larger magnitudes of reward. Additional experiments demonstrated that the effect of consumption did not extend to a secondary reward (money), a tasteless, noncaloric primary reward (water), or a sweet, noncaloric reward (aspartame). However, a tasteless caloric reward (maltodexrin) did induce overproductions of time, although this effect did not scale with reward magnitude. These results suggest that the consumption of caloric primary rewards can alter time perception, which may be a psychophysiological mechanism by which organisms regulate homeostatic balance.
Impact of Retrievable Stents on Acute Ischemic Stroke Treatment

BACKGROUND AND PURPOSE: Retrievable stents combine the high recanalization rate of stents and the capability of removing the thrombus offered by mechanical thrombectomy devices. We hypothesized that retrievable stents shorten time to recanalization in the multimodal approach for endovascular stroke treatment. MATERIALS AND METHODS: Forty consecutive patients with acute ischemic stroke and undergoing endovascular therapy were included. Treatment included thromboaspiration, thrombus disruption, thrombolysis, PTA, and stent placement. In 17 patients, a retrievable stent was used (group A) in addition to multimodal therapy. The remaining 23 patients constituted group B. Baseline characteristics, occlusion sites, urokinase dose, recanalization rate, and time to recanalization were compared between the groups. RESULTS: Median NIHSS scores were higher in group A compared with group B on admission (19 versus 12.5; P = .018) but were not significantly different at day 1 (14 versus 10; P = .6). Intra-arterial thrombolysis was used in significantly fewer patients of group A than group B (53% versus 87%, respectively; P = .017), and median urokinase dose was lower in group A than in group B (250,000 IU versus 700,000 IU; P = .006). Time to recanalization was significantly shorter in group A compared with group B (median time to recanalization 52.5 minutes versus 90 minutes, respectively; P = .001). Recanalization rate was higher in group A than group B (94% versus 78%; P = .17). CONCLUSIONS: Addition of retrievable stents to the multimodal endovascular approach for acute ischemic stroke treatment significantly reduces time to recanalization and further increases the recanalization rate.
Comparisons of movement characteristics and intermittent exercise pattern in ball games

The purpose of this study was to compare the movement characteristics and intermittent exercise pattern in five ball games: basketball, handball, soccer, field hockey, and lacrosse. In the respective events, six to twelve male college players in Division I were chosen as subjects, and their movement distances and velocities were measured using two-dimensional direct linear transformation (DLT). The main results were as follows:1. Movement distances during the first half were the longest in soccer, followed in order by field hockey, handball, basketball, and lacrosse. However, the movement distance per playing time in each game was longer in field hockey and lacrosse than in the others.2. The rates of low-velocity movement were higher in basketball and soccer, and those of high-velocity movements were higher in handball and lacrosse, than in the others.3. Mean movement durations during low-velocity and high-velocity movements were: basketball 2.78 and 0.64 s; handball 3.54 and 0.67 s; soccer 6.67 and 1.33 s; field hockey 3.70 and 0.96 s; and lacrosse 2.67 and 1.05 s.These results clarified the characteristics of intermittent exercise patterns in each event. In basketball, there were many changes in movement velocity and direction, but the subjects hardly reached top speed. In handball, there was alternation between brief high-velocity movements and prolonged low-velocity movements. In soccer, movement duration was longer, and the mean velocity during low-velocity movement was faster than in the other events. In field hockey, in both low- and high-velocity movements, velocity and duration were comparatively fast and long, respectively. In lacrosse, players performed prolonged high-velocity movement in the field, and took sufficient recovery in the bench area.
An efficient secure data aggregation scheme for wireless sensor networks

Wireless sensor networks (WSNs) often consists of a large number of low-cost sensor nodes that have strictly limited sensing, computation, and communication capabilities. Due to these unique specifications and a lack of tamper-resistant hardware, devising security protocols for WSNs is complex. Previous studies show that data transmission consumes much more energy than computation. Data aggregation can greatly help to reduce this consumption by eliminating redundant data. As wireless sensor networks are usually deployed in remote and hostile environments and used to transmit sensitive information, sensor nodes are prone to node compromise attacks and hence security issues such as data confidentiality and integrity are extremely important. A novel approach, which uses homomorphic encryption and additive digital signatures, is proposed to provide confidentiality, integrity for secure data aggregation in WSNs. The performance evaluation shows that the proposed scheme is efficient and scalable for large WSNs.
ASYMETRIE HEMISPHERIQUE DANS LES AMUSIES

: The search of hemispheric dominance for music has been for long the main aim of the study of amusias. Musical abilities were first localized in the left hemisphere, then in the right one. In the light of the available data, these two diverging conceptions do not appear paradoxical anymore. Indeed, brain injury on either side can provoke musical deficits. However, the nature of the deficit seems to depend on the particular hemisphere damaged. Right-sided lesions appear to disturb the melodic aspects of musical sequences while left-sided lesions seem to deteriorate the rhythmic aspects. Although the clinical literature involves insightful suggestions on how the musical abilities are organized, especially with respect to linguistic functions, these indications are not sufficient to provide a clear picture of the nature of the functional differences for music between hemispheres. Research is not systematic. Commentaries and suggestions are proposed to guide future investigations.
Sinhala Grapheme-to-Phoneme Conversion and Rules for Schwa Epenthesis

This paper describes an architecture to convert Sinhala Unicode text into phonemic specification of pronunciation. The study was mainly focused on disambiguating /schwa/ and /a/ vowel epenthesis for consonants, which is one of the significant problems found in Sinhala. This problem has been addressed by formulating a set of rules. The proposed set of rules was tested using 30,000 distinct words obtained from a corpus and compared with the same words manually transcribed to phonemes by an expert. The Grapheme-to-Phoneme (G2P) conversion model achieves 98% accuracy.

Effects of mood on visual cognition of Navon stimuli of different sizes: The usefulness of threshold as an index

視角の異なるNavon刺激を用いて，観察者の注意の焦点が，否定的気分によって，これらの刺激に含まれる小さな局所的特徴に合わせられ，肯定的気分によって，大きな大域的特徴に合わせられるという仮説を検証した．気分操作には，音楽あるいは絵本を用い，72名の実験参加者には，気分を操作する前と操作した後とで，各刺激に対して局所と大域のどちらの特徴がはっきりと印象深く見えたかを尋ねた．刺激が大きいほど局所への反応は増すことから，局所への反応数をもとに，大域への反応が局所への反応に取って代わる，すなわち閾値となる刺激の大きさを決定した．結果として，否定的気分時にはその閾値の低下がみられたが，肯定的気分時には閾値に変化はみられなかった．これらの結果に基づき，肯定的気分の効果は，安定して生じるものでなく，大域的特徴が肯定的な感情価に関係するとき，あるいは大域的特徴がひときわ利用しやすいときに生じるものであり，これに対して否定的気分の効果は，そうした関係性に依存しないと考察した．
Mouse Germ Cell Development in-vivo and in-vitro

In mammalian development, primordial germ cells (PGCs) represent the initial population of cells that are committed to the germ cell lineage. PGCs segregate early in development, triggered by signals from the extra-embryonic ectoderm. They are distinguished from surrounding cells by their unique gene expression patterns. Some of the more common genes used to identify them are Blimp1, Oct3/4, Fragilis, Stella, c-Kit, Mvh, Dazl and Gcna1. These genes are involved in regulating their migration and differentiation, and in maintaining the pluripotency of these cells. Recent research has demonstrated the possibility of obtaining PGCs, and subsequently, mature germ cells from a starting population of embryonic stem cells (ESCs) in culture. This phenomenon has been investigated using a variety of methods, and ESC lines of both mouse and human origin. Embryonic stem cells can differentiate into germ cells of both the male and female phenotype and in one case has resulted in the birth of live pups from the fertilization of oocytes with ESC derived sperm. This finding leads to the prospect of using ESC derived germ cells as a treatment for sterility. This review outlines the evolvement of germ cells from ESCs in vitro in relation to in vivo events.
Bail or Jail? The Practical Operation of the Bail Act 1976

Recent changes to the law relating to bail have increased the power of criminal justice agencies to arrest and monitor defendants granted bail by the police or the courts, refuse the grant of bail, and appeal against a magistrates' decision to grant bail. These measures provide overwhelming evidence of the erosion of rights of suspects and defendants in the remand process who are, in theory at least, innocent until proven guilty. They were introduced to redress the perceived imbalance between the powers of the prosecution and the rights of defendants. However, evidence from a research project carried out into the practical operation of the remand process suggests that the remand process already favoured the prosecution and that many of the rights afforded to defendants were not utilized in practice. As a result, the changes in the law were unnecessary and will result in an increase in unnecessary custodial remands. One of the major law and order debates during the 1990s concerned the issue of offending on bail. This debate was spearheaded by the police, backed up by their own research findings.1 They argued that defendants were routinely abusing bail and they and the courts lacked the power to prevent this occurring. This argument followed a similar line to those relating to other areas of the criminal justice process which centred around the contention that the balance of the process had moved too far in favour of the accused. In other words, the rights of suspects and defendants had become so strong that factually guilty people were able to abuse the system and evade prosecution and conviction. One of the hallmarks of these debates was the use of specific atypical cases to illustrate the ability of accused persons to abuse the system, for example, the case in Gloucester of a man released on bail on a charge of rape who murdered a women while awaiting trial on the first charge. The arguments presented by the police were strengthened by extensive media coverage which brought this issue into the public eye and created a moral panic about persistent offenders who
A metric model of PCF

We introduce a computationally adequate metric model of PCF, based on the fact that the category of non-expansive maps of complete bounded ultrametric spaces is cartesian closed. The model captures certain temporal aspects of higher-type computation and contains both extensional and intensional functions. We show that Scott’s model arises as its extensional collapse. The intensional aspects of the metric model are illustrated via a Gödel-number-free version of Kleene’s T -predicate.
Segmentation of Pulmonary Nodule in CT Image Based on Level Set Method

As pulmonary nodule scatters everywhere in the initial period of lung diseases and the edges of the pulmonary nodule is irregular, which requires us to seek the pulmonary nodule in the whole lung image and recognize it accurately. The global segmentation is just the advantage of level set method based on Mumford-Shah model, but nobody home and abroad applies it to recognizing the pulmonary nodule. Therefore, this paper first introduces the model in recognizing the pulmonary nodule. It proves that it is feasible to use level set method based on Mumford-Shah model to recognize the pulmonary nodule.
Bandwidth-sharing in overloaded networks

Bandwidth-sharing networks as considered by Massoulie & Roberts provide a natural modeling framework for describing the dynamic flow-level interaction among elastic data transfers. Under mild assumptions, it has been established that a wide family of so-called alpha-fair bandwidth-sharing strategies achieve stability in such networks provided that no individual link is overloaded. In the present paper we focus on alpha-fair bandwidth-sharing networks where the load on one or several of the links exceeds the capacity. Evidently, a well-engineered network should not experience overload, or even approach overload, in normal operating conditions. Yet, even in an adequately provisioned system with a low nominal load, the actual traffic volume may significantly fluctuate over time and exhibit temporary surges. Furthermore, gaining insight in the overload behavior is crucial in analyzing the performance in terms of long delays or low throughputs as caused by large queue build-ups. The way in which such rare events tend to occur, commonly involves a scenario where the system temporarily behaves as if it experiences overload. In order to characterize the overload behavior, we examine the fluid limit, which emerges from a suitably scaled version of the number of flows of the various classes. Focusing on linear solutions to the fluid-limit equation, we derive a fixed-point equation for the corresponding asymptotic growth rates. It is proved that a fixed-point solution is also a solution to a related strictly concave optimization problem, and hence exists and is unique. The results are illustrated for linear topologies and star networks as two important special cases.
Violent young offenders : an examination of how psychopathy and instrumentality inform our understanding of aggression

Youth violence and aggression are significant problems facing today’s society. While most young offenders commit relatively minor crimes, a small proportion is involved in more serious, violent crimes. Previous explanations of participation in violence indicate that psychopathy is a robust predictor of aggressive behaviours for both adult (e.g., Walsh & Walsh, 2006) and youth offenders (e.g., Flight & Forth, 2007). Woodworth and Porter (2002) proposed a selective impulsivity hypothesis to reconcile the psychopath’s impulsive nature and propensity for goal-directed violence. Specifically, they suggested that as the severity of crime increases, psychopaths will actively monitor their impulsive tendencies, employing less reactive violence when the consequences are highest (for example, when committing homicide) (Agar, 2009; Woodworth & Porter, 2002). The current investigation is the first to directly test this hypothesis in violent youth offenders. Using a sample of 100 young offender files from British Columbia, the results supported the selective impulsivity hypothesis in youths. Of particular interest, a relationship between the interpersonal features of psychopathy and instrumental violence was revealed. Interpersonally callous traits were related to an increase in use of instrumental violence. Findings are discussed in light of current theories of aggression, and suggestions for future directions are considered.
Long term reshaping of language, sensory, and motor maps after glioma resection: a new parameter to integrate in the surgical strategy

Objectives: To describe cortical reorganisation and the effects of glioma infiltration on local brain function in three patients who underwent two operations 12–24 months apart. Methods: Three patients who had no neurological deficit underwent two operations for low grade glioma, located in functionally important brain regions. During each operation, local brain function was characterised by electrical mapping and awake craniotomy. Results: Language or sensorimotor areas had been invaded by the tumour at the time of the first operation, leading to incomplete glioma removal in all cases. Because of a tumour recurrence, the patients were reoperated on between 12 and 24 months later. Functional reorganisation of the language, sensory, and motor maps was detected by electrical stimulation of the brain, and this allowed total glioma removal without neurological sequelae. Conclusions: These findings show that surgical resection of a glioma can lead to functional reorganisation in the peritumorous and infiltrated brain. It may be that this reorganisation is directly or indirectly caused by the surgical procedure. If this hypothesis is confirmed by other studies, the use of such brain plasticity potential could be used when planning surgical options in some patients with low grade glioma. Such a strategy could extend the limits of tumour resection in gliomas involving eloquent brain areas without causing permanent morbidity.
A Drosophila dopamine 2-like receptor: Molecular characterization and identification of multiple alternatively spliced variants

Dopamine is an important neurotransmitter in the central nervous system of both Drosophila and mammals. Despite the evolutionary distance, functional parallels exist between the fly and mammalian dopaminergic systems, with both playing roles in modulating locomotor activity, sexual function, and the response to drugs of abuse. In mammals, dopamine exerts its effects through either dopamine 1-like (D1-like) or D2-like G protein-coupled receptors. Although pharmacologic data suggest the presence of both receptor subtypes in insects, only cDNAs encoding D1-like proteins have been isolated previously. Here we report the cloning and characterization of a newly discovered Drosophila dopamine receptor. Sequence analysis reveals that this putative protein shares highest homology with known mammalian dopamine 2-like receptors. Eight isoforms of the Drosophila D2-like receptor (DD2R) transcript have been identified, each the result of alternative splicing. The encoded heptahelical receptors range in size from 461 to 606 aa, with variability in the length and sequence of the third intracellular loop. Pharmacologic assessment of three DD2R isoforms, DD2R-606, DD2R-506, and DD2R-461, revealed that among the endogenous biogenic amines, dopamine is most potent at each receptor. As established for mammalian D2-like receptors, stimulation of the Drosophila homologs with dopamine triggers pertussis toxin-sensitive Gi/o-mediated signaling. The D2-like receptor agonist, bromocriptine, has nanomolar potency at DD2R-606, -506, and -461, whereas multiple D2-like receptor antagonists (as established with mammalian receptors) have markedly reduced if any affinity when assessed at the fly receptor isoforms. The isolation of cDNAs encoding Drosophila D2-like receptors extends the range of apparent parallels between the dopaminergic system in flies and mammals. Pharmacologic and genetic manipulation of the DD2Rs will provide the opportunity to better define the physiologic role of these proteins in vivo and further explore the utility of invertebrates as a model system for understanding dopaminergic function in higher organisms.
