Evaluation of system losses due to harmonics in medium voltage distribution networks

Power system harmonics are a known cause to failure, disoperation or premature aging of customer's equipment. It also causes additional losses in a distribution network that influence the planning and design of future networks and the cost of serving energy. The impact on apparent power capacity and active energy losses are evaluated in this paper, based on actual data recorded in a typical South African medium voltage distribution network. The goal is to create a classification tool for local utilities to estimate losses and the impact on planning and revenue caused by harmonic distortion levels in a distribution network.
Characterization of pURB500 from the archaeon Methanococcus maripaludis and construction of a shuttle vector

The complete sequence of the 8,285-bp plasmid pURB500 from Methanococcus maripaludis C5 was determined. Sequence analysis identified 18 open reading frames as well as two regions of potential iterons and complex secondary structures. The shuttle vector, pDLT44, for M. maripaludis JJ was constructed from the entire pURB500 plasmid and pMEB.2, an Escherichia coli vector containing a methanococcal puromycin-resistance marker (P. Gernhardt, O. Possot, M. Foglino, L. Sibold, and A. Klein, Mol. Gen. Genet. 221:273-279, 1990). By using polyethylene glycol transformation, M. maripaludis JJ was transformed at a frequency of 3.3 x 10(7) transformants per microg of pDLT44. The shuttle vector was stable in E. coli under ampicillin selection but was maintained at a lower copy number than pMEB.2. Based on the inability of various restriction fragments of pURB500 to support maintenance in M. maripaludis JJ, multiple regions of pURB500 were required. pDLT44 did not replicate in Methanococcus voltae.
The Effects of Acetate-Free Citrate-Containing Dialysate on Calcium Metabolism and Fatigue in Patients on Maintenance Hemodialysis

Although the significance of acetate-free citrate with 3.0 mEq/L Ca-containing-dialysate (A(−)D) has been reported, its effective Ca level and the overtreatment needed to correct metabolic acidosis on the basis of serum whole parathyroid hormone (wPTH) and arterial pH have not been evaluated in detail. Furthermore, recent reports have suggested the beneficial effect of citrate on fatigue, which is a significant risk for cardiovascular disease. Thirty-two hemodialysis patients receiving acetate with 2.75 mEq/L Ca-containing dialysate (A(+)D) participated in the present A(+)D to A(–)D one-arm switch study over 4 weeks. Predialysis wPTH increased significantly from 85.1 ± 59.0 pg/mL during hemodialysis A(+)D to 106.8 ± 78.8 pg/mL (p = 0.0015) after 2 weeks of A(–)D treatment. Predialysis arterial pH and bicarbonate levels significantly increased from 7.335 ± 0.037 to 7.370 ± 0.035 (p < 0.0001) and from 19.6 ± 2.1 mEq/L to 21.3 ± 1.7 mEq/L (p = 0.0001), respectively, whereas post-dialysis arterial pH and bicarbonate levels significantly increased from 7.447 ± 0.022 to 7.473 ± 0.027 (p < 0.0001) and from 25.2 ± 1.0 mEq/L to 28.1 ± 1.0 mEq/L (p < 0.0001). When all patients were divided into two equal-sized groups by fatigue score, the improvement in the fatigue score was significantly greater in the high group (Δ1.8 ± 3.7) than in the low group (Δ–0.8 ± 2.3) (p = 0.0252). This study demonstrated that the effective Ca level might be significantly lower in A(−)D than in A(+)D and metabolic acidosis was improved more strongly in A(–)D relative to that in A(+)D because of the higher bicarbonate concentration in A(–)D. Furthermore, A(–)D had a beneficial effect on intradialytic hemodynamics and fatigue sensation.
Trajectory control of a mobile manipulator in the presence of base disturbance

A mobile manipulator is typically an assembly of a mobile robot base and an on-board manipulator arm. As the manipulator arm is mounted over the mobile robot base, the controller has the additional task of taking care of the disturbances of the mobile robot due to the dynamic interactions between the mobile robot base and manipulator arm. In the present work, dynamic models for the manipulator arm and an omni-wheeled mobile robot base were developed separately and then both were combined. Two control strategies, namely only manipulator arm control (OMAC) and simultaneous manipulator and base control (SMBC) were developed for the effective control of tip trajectory. In both strategies, an amnesia recovery coupled with classical proportional integral and derivative (PID) control was used. The bond graph methodology was used for the development of the dynamic model and control for the mobile manipulator. Simulation results are presented to illustrate the efficacy of the two control strategies.
School-based staff development : collaborative planning & preparation for change.

School-Based Staff Development; Collaborative Planning and Preparation for Change (February 1981) 'J®3^ri6tte P» Esposito / B»A« / Jersey City State College M.A., Villanova University, Ed.D. , University of Massachusetts Directed by: Professor Harvey B. Scribner In recent years, increased interest in the education of experienced teachers has occurred as a result of our longoverdue recognition that teachers are the most important link between plans for educational improvement and students who need help. Current research stresses the need to give ^ teachers, the ultimate implementers of change, the opportun'i'^ ities, support and resources to make instructional innova/ tions their own, to develop rationales and to recreate strategies that fit their unique local contexts and needs. It is widely acknowledged that despite the energy, commitment and money applied to past training programs for experienced teachers, these programs have not, in most cases, had a significant impact on the schools. In order to reverse this trend, many studies now cite the importance of school-site problem-solving that flows from and is related to staff-identified concerns and that utilizes teacheradministrator expertise and collegial sharing. Thus, "what to do" has become clearer; "how to do it" requires further
Contrats de contexte pour la gestion de contexte répartie

Les applications qui s'executent dans les environnements ambiants ont besoin d'informations de contexte pour s'adapter aux changements de l'environnement. Un defi majeur qui suscite l'interet des chercheurs est de permettre un echange de l'information de contexte. Ce travail s'interesse particulierement a la modelisation de la repartition de la gestion de contexte. La repartition des informations de contexte doit etre consideree des le debut de la modelisation. Un modele de repartition des donnees de contexte permet l'expression des contraintes de contexte et l'acheminement des informations de contexte sans ambiguite entre les fournisseurs ou les consommateurs d'informations de contexte, et le service de gestion de contexte, ainsi qu'entre les differents composants du service de gestion de contexte. Cela nous amene a definir un modele de contrat de contexte. Pour assurer une communication asynchrone entre les fournisseurs et les consommateurs d'informations de contexte, nous nous appuyons sur le modele d'interaction des Systemes Repartis a Base d'Evenements (SRBE)
Rapid nongenomic effects of aldosterone in mineralocorticoid-receptor-knockout mice.

In addition to genomic effects of aldosterone, rapid nongenomic effects of steroids have been reported in various tissues that were clearly incompatible with a genomic action of aldosterone. Rapid effects of aldosterone involve second messengers such as calcium and cAMP. Specific high affinity binding sites for aldosterone have been characterized in membranes for different cells, which probably transmit those rapid steroid effects. To date, it is unclear if these binding sites are modified classical mineralocorticoid receptors (MR) or if they represent an unrelated receptor protein. The aim of the present study was to investigate whether rapid aldosterone action still occurs in the absence of the classical MR. For this purpose we used the model of MR knockout mice. Rapid effects were analyzed in skin cells, measuring intracellular calcium and cAMP levels after stimulation with aldosterone. We found that rapid effects are not only present in MR knockout mice, but that the effects are even larger than in wild-type mice cells. The results of the present study demonstrate that the classic MR is dispensable for rapid aldosterone action. The study, thus, proves that a receptor different from the classic intracellular receptor is involved in rapid aldosterone signaling.

Second-order statistical characterization of the filter bank and its elements

This correspondence proposes an alternative scheme for characterizing the wide sense cyclostationary (WSCS) processes and applies it for the analysis of the filter banks whose output is WSCS for wide sense stationary and WSCS inputs. The proposed representation clearly illustrates the kind of transformation taking place in multiscale stochastic systems. These relationships are extended to the filter bank to make clear the effect of the various stages of the filter bank on WSCS processes.

An Approach to Construct a Named Entity Annotated English-Vietnamese Bilingual Corpus

Manually constructing an annotated Named Entity (NE) in a bilingual corpus is a time-consuming, labor--intensive, and expensive process, but this is necessary for natural language processing (NLP) tasks such as cross-lingual information retrieval, cross-lingual information extraction, machine translation, etc. In this article, we present an automatic approach to construct an annotated NE in English-Vietnamese bilingual corpus from a bilingual parallel corpus by proposing an aligned NE method. Basing this corpus on a bilingual corpus in which the initial NEs are extracted from its own language separately, the approach tries to correct unrecognized NEs or incorrectly recognized NEs before aligning the NEs by using a variety of bilingual constraints. The generated corpus not only improves the NE recognition results but also creates alignments between English NEs and Vietnamese NEs, which are necessary for training NE translation models. The experimental results show that the approach outperforms the baseline methods effectively. In the English-Vietnamese NE alignment task, the F-measure increases from 68.58% to 79.77%. Thanks to the improvement of the NE recognition quality, the proposed method also increases significantly: the F-measure goes from 84.85% to 88.66% for the English side and from 75.71% to 85.55% for the Vietnamese side. By providing the additional semantic information for the machine translation systems, the BLEU score increases from 33.04% to 45.11%.
Alcohol and Malt Liquor Availability and Promotion and Homicide in Inner Cities

We investigated the role of the alcohol environment in explaining disparities in homicide rates among minorities in 10 cities in the United States using 2003 data from the Malt Liquor and Homicide study. We hypothesized that (a) higher concentrations of African Americans would be associated with higher homicide rates, as well as higher alcohol and malt liquor availability and promotion, and (b) the relationship between neighborhood racial/ethnic concentration and homicide would be attenuated by the greater alcohol and malt liquor availability and promotion in African American neighborhoods. Hypotheses were tested using separate Poisson, linear, and logistic regression models that corrected for spatial autocorrelation. Census block groups served as the unit of analysis (n = 450). We found that higher concentrations of African Americans were associated with higher homicide rates as well as greater alcohol availability, especially malt liquor availability. The promotion of malt liquor on storefronts was also significantly greater in African American than in other neighborhoods. However, none of the measures representing alcohol or malt liquor availability and promotion variables changed the effect of neighborhood racial/ethnic concentration on homicide. Limitations and implications of our findings are discussed.
Study on VMI Inventory Control Mode based on the Third-Party Logistics

Adding the third party logistics enterprises between the suppliers and the retailers is a kind of the development of VMI mode, in this mode; inventory pressure is transferred to the third party logistics enterprise. In view of this situation, the VMI inventory control model which treats total inventory control costs as the objective function is built based on from four dimensions: the inventory holding costs, the fixed delivery costs, replenishment costs and customer waiting costs. After solving the model and sensitivity analyzing related parameters, it can be inferred that related parameters in the VMI model of the introduction of the third party logistics have effects on inventory control costs.
Correction: The Evolutionary Biology of Musical Rhythm: Was Darwin Wrong?

In The Descent of Man, Darwin speculated that our capacity for musical rhythm reflects basic aspects of brain function broadly shared among animals. Although this remains an appealing idea, it is being challenged by modern cross-species research. This research hints that our capacity to synchronize to a beat, i.e., to move in time with a perceived pulse in a manner that is predictive and flexible across a broad range of tempi, may be shared by only a few other species. Is this really the case? If so, it would have important implications for our understanding of the evolution of human musicality.
An ARQ technique using related parallel and serial concatenated convolutional codes

We propose a new type-II code-combining hybrid automatic repeat request (ARQ) strategy that uses both parallel and serial concatenated convolutional codes (PCCCs and SCCCs). The ARQ technique is based on the observation that a PCCC can be represented by an equivalent punctured SCCC. The initial transmission is the PCCC. When a retransmission is requested, the system only transmits the additional parity bits that, together with the previously transmitted PCCC bits, constitute the related SCCC. Simulation results show remarkable power efficiency and throughput efficiency when using the proposed system.
and Asset Pricing

We consider a model of trade in a limit order market for a single asset, and examine the properties of the microstructure noise (i.e., the dierence between the transaction price and the fundamental value). The asset has a common value; in addition, each trader has a private value for it. Traders randomly arrive at the market, after choosing whether to purchase information about the common value. They may either post prices or accept posted prices. If a trader’s order has not executed, he randomly reenters the market, and may change his previous order. The model is thus a dynamic stochastic game with asymmetric information. We numerically solve for equilibrium in the model, and simulate market outcomes. Agents with no intrinsic benefit from trade have the highest value for information and also tend to supply liquidity. Agents’ incentives to acquire information and their subsequent equilibrium trading behavior changes systematically with the underlying volatility of the asset. In equilibrium, the limit order market acts as a “volatility multiplier”: prices are more volatile than the fundamental value of the asset. This eect increases when the fundamental volatility of the asset is higher or when there is asymmetric information across traders, due to a change in the composition of trader types that choose to provide liquidity. Further, changes in the microstructure noise are negatively correlated with changes in the fundamental value itself. This implies that asset betas estimated from high-frequency data will be incorrect. Thus, microstructure noise and other variables correlated with it may spuriously appear to explain cross-sectional asset prices. Finally, we show that the microstructure noise itself has positive autocorrelation.
Celecoxib versus diclofenac and omeprazole in reducing the risk of recurrent ulcer bleeding in patients with arthritis.

BACKGROUND Current guidelines recommend that patients at risk for ulcer disease who require treatment for arthritis receive nonsteroidal antiinflammatory drugs (NSAIDs) that are selective for cyclooxygenase-2 or the combination of a nonselective NSAID with a proton-pump inhibitor. We assessed whether celecoxib would be similar to diclofenac plus omeprazole in reducing the risk of recurrent ulcer bleeding in patients at high risk for bleeding. METHODS We studied patients who used NSAIDs for arthritis and who presented with ulcer bleeding. After their ulcers had healed, we randomly assigned patients who were negative for Helicobacter pylori to receive either 200 mg of celecoxib twice daily plus daily placebo or 75 mg of diclofenac twice daily plus 20 mg of omeprazole daily for six months. The end point was recurrent ulcer bleeding. RESULTS In the intention-to-treat analysis, which included 287 patients (144 receiving celecoxib and 143 receiving diclofenac plus omeprazole), recurrent ulcer bleeding occurred in 7 patients receiving celecoxib and 9 receiving diclofenac plus omeprazole. The probability of recurrent bleeding during the six-month period was 4.9 percent (95 percent confidence interval, 3.1 to 6.7) for patients who received celecoxib and 6.4 percent (95 percent confidence interval, 4.3 to 8.4) for patients who received diclofenac plus omeprazole (difference, -1.5 percentage points; 95 percent confidence interval for the difference, -6.8 to 3.8). Renal adverse events, including hypertension, peripheral edema, and renal failure, occurred in 24.3 percent of the patients receiving celecoxib and 30.8 percent of those receiving diclofenac plus omeprazole. CONCLUSIONS Among patients with a recent history of ulcer bleeding, treatment with celecoxib was as effective as treatment with diclofenac plus omeprazole, with respect to the prevention of recurrent bleeding. Renal toxic effects are common in high-risk patients receiving celecoxib or diclofenac plus omeprazole.
A first step towards providing health-care agent-based services to mobile users

The aim of the Agent Cities project is to build agent-based information services for mobile users. In the framework of this project it is interesting to consider the possibility of deploying agents that provide Health Care-related services. In this paper we report the design and construction of a multi-agent system (MAS) that is composed of agents that provide medical services. The MAS contains agents that allow the user to search for medical centres satisfying a given set of requirements, to access his/her medical record or to make a booking to be visited by a particular kind of doctor.
Developmental and molecular analysis of Deformed; a homeotic gene controlling Drosophila head development

The characteristic morphology of many elements of the Drosophila body plan is crucially dependent upon the proper spatial expression of homeotic selector genes. The Deformed locus, which we isolated by virtue of its homology to the homeo box, is a candidate for a homeotic selector in the head region of the developing embryo. Here we show that null mutants of Deformed result in a loss of pattern elements derived from the maxillary and mandibular segments, and a duplication of a cuticular element of the larval head skeleton. Molecular analysis of the locus shows that Dfd transcripts are encoded in five exons distributed over 11 kb. The major transcript of 2.8 kb contains a 1758‐bp open reading frame that would translate to yield a 63.5‐kd protein containing a homeo domain and conspicuous regions of monotonic amino acid sequences. The Dfd protein exhibits extensive homology to a protein encoded by a Xenopus homeo box gene, Xhox 1A, suggesting that the Xenopus gene is the frog homologue of Dfd.
Réseaux sociaux et PME : La distance psychique fait-elle encore peur aux petites entreprises dans un processus international ?

The aim of this paper is to contribute to better understanding the potential roles of social media to overcome the existing psychological distance between the two countries in the context of internationalization for small and medium enterprises. Once the company decides to internationalize, it must directly face to the distance. This is an obstacle for smaller companies because different barriers come interpose (language, culture, political, economic, .). Small and medium sized enterprises are afraid to invest too distant markets. However, aware of little
Attachment of Enteric Viruses to Bottles

ABSTRACT Storage of water that was deliberately contaminated with enteric viruses in polyethylene terephthalate (PET) bottles led to a rapid decrease of the apparent viral load, thereby hampering the development of samples for a collaborative evaluation of viral detection methods for bottled water. To determine if this decrease was due to spontaneous inactivation or to adhesion, an elution protocol was developed and combined with a rapid and sensitive real-time reverse transcription-PCR-based method to quantify adsorbed norovirus (NV), hepatitis A virus (HAV), and rotavirus (RV) on bottle walls. The NV retention on PET bottle walls after 20 and 62 days reached an average level of 85% and 95% of the recovered inoculum, respectively. HAV and RV also showed adsorption onto PET bottles, reaching 90% and 80%, respectively, after 20 days of storage. NV and RV attachment was demonstrated to be dependent on the presence of autochthonous flora, whereas HAV adsorption was independent of it. Application of the elution and viral detection protocol to 294 commercially available water bottles obtained from 25 different countries did not give any positive result, thereby providing further evidence that the sources used for this product are free from enteric viruses and support for the theory that bottled water is not a vehicle for viral diseases.
