Evaluating Generating Unit Unavailability Using Bayesian Power Priors

Generating unit unavailability assessment is an important task in the power system generation expansion planning aimed at managing an acceptable degree of security of supply. In the case of the newly installed or planned units, the sample size of the data for unavailability assessment is limited and inadequate to provide the desired accuracy in the unavailability estimation. A new concept based on the Bayesian power prior approach has been developed to utilize the data from similar generating units. The original contribution of the present work is a model that incorporates the data of unavailability from other generating units into the statistical analysis of unavailability of the analysed generating unit to improve the accuracy of the estimation. The empirical results show that for unavailability estimation, the power prior Bayesian approach exhibits better than the classical statistical approach in both the standard error of estimate and confidence interval as the measures of accuracy.
Answering conceptual queries with Ferret

Programmers seek to answer questions as they investigate the functioning of a software system, such as "which execution path is being taken in this case? " Programmers attempt to answer these questions, which we call conceptual queries, using a variety of tools. Each type of tool typically highlights one kind of information about the system, such as static structural information or control-flow information. Unfortunately for the programmer, the tools seldom directly answer the programmer's conceptual queries. Instead, the programmer must piece together results from different tools to determine an answer to the initial query. At best, this process is time consuming and at worst, this process can lead to data overload and disorientation. In this paper, we present a model that supports the integration of different sources of information about a program. This model enables the results of concrete queries in separate tools to be brought together to directly answer many of a programmer's conceptual queries. In addition to presenting this model, we present a tool that implements the model, demonstrate the range of conceptual queries supported by this tool, and present the results of use of the conceptual queries in a small field study.
How About the Real Capacity of Cell-ID Based Algorithms for LBS

We investigate the location algorithms of which parameters could be extracted from measurement reports. A field measurement was implemented for collecting data, and algorithms were programmed for examining their accuracies. The experiment results represent diversity from the previous work and our theoretical analysis. The position accuracies are ungratified and some algorithms which have been considered as high accuracies, in contrast, largen the errors. We also suggest an improvement. As a simple threshold to obstruct the rough data, position accuracy and stability could be enhanced significantly.
Indirect Effect of Catecholamines on Development of Insulin Resistance in Skeletal Muscle From Diabetic Rats

The role of an increased sympathetic activation in the development of insulin resistance in diabetic skeletal muscle was investigated. Epitrochlearis muscles from rats with streptozocin-induced diabetes and from controls were incubated in vitro for 0.5–12.0 h. Diabetes decreased maximal insulin-stimulated (20 mU/ml) glucose transport capacity by 60% (P < .001), but this decreased insulin responsiveness returned to normal on in vitro incubation (3.79 ± 0.59 before vs. 8.92 ± 0.64 μmol · ml1 · h−1 after 12 h of incubation). The reversal of decreased insulin responsiveness in diabetic muscles did not require the presence of insulin and was not affected by the presence of 5.0 × 10−8 M of epinephrine. However, it was possible to partially prevent the development of insulin resistance with regard to glucose transport by treating the rats with the β-adrenergic antagonist propranolol (0.5 mg/kg) every 12 h during the entire 72-h period in which the animals were kept diabetic (insulin responsiveness was 3.16 ± 0.40 μmol · ml−1 · h−1 saline-injected group vs. 5.55 ± 0.46 μmol · ml−1 for propranolol-treated group). This effect was not present after a single injection of the drug 2 h before the experiment or when propranolol treatment was withdrawn 12 h before the experiment. The β-adrenergic blockade markedly reduced the plasma concentration of free fatty acids (0.5 ± 0.01 (μmol/ml for propranolol-treated rats vs. 1.1 ± 0.1 μmol/ml for saline-treated rats; P < .001). These results indicate that catecholamines, acting indirectly by another mediator, possibly free fatty acids, are involved in the development of insulin resistance with regard to glucose transport in diabetic skeletal muscle. Furthermore, the results suggest that the effect of catecholamines is of a chronic, rather than acute, nature.
Similarity Search in Arbitrary Subspaces Under Lp-Norm

Similarity search has been widely used in many applications such as information retrieval, image data analysis, and time-series matching. Specifically, a similarity query retrieves all data objects in a data set that are similar to a given query object. Previous work on similarity search usually consider the search problem in the full space. In this paper, however, we propose a novel problem, subspace similarity search, which finds all data objects that match with a query object in the subspace instead of the original full space. In particular, the query object can specify arbitrary subspace with arbitrary number of dimensions. Since traditional approaches for similarity search cannot be applied to solve the proposed problem, we introduce an efficient and effective pruning technique, which assigns scores to data objects with respect to pivots and prunes candidates via scores. We propose an effective multipivot-based method to pre-process data objects by selecting appropriate pivots, where the entire procedure is guided by a formal cost model, such that the pruning power is maximized. Finally, scores of each data object are organized in sorted list to facilitate an efficient subspace similarity search. Extensive experiments have verified the correctness of our cost model and demonstrated the efficiency and effectiveness of our proposed approach for the subspace similarity search.
Entropic transport of finite size particles

Transport of spherical Brownian particles of finite size possessing radii R ≤ Rmax through narrow channels with varying cross-section width is considered. Applying the so-called Fick–Jacobs approximation, i.e. assuming fast equilibration in the direction orthogonal to the channel axis, the 2D problem can be described in terms of a 1D effective dynamics in which bottlenecks cause entropic barriers. Geometrical confinements result in entropic barriers which the particles have to overcome in order to proceed in the transport direction. The analytic findings for the nonlinear mobility for the transport are compared with precise numerical simulation results. The dependence of the nonlinear mobility on the particle size exhibits a striking resonance-like behavior as a function of the relative particle size ρ = R/Rmax; this latter feature renders possible new effective particle separation scenarios.
Becoming a leader: A co-produced autoethnographic exploration of situated learning of leadership practice

The article examines the development of situated leadership practice through an autoethnographic study of the first three months of being in the role of a chief operating officer. The argument for using an autoethnographic approach is in response to the dearth of in-depth research on the development of leadership practice from a relational, social and situated perspective. The article makes a contribution to management learning by exploring aspects of situated curriculum within a manager’s legitimate participation influencing the development of situated leadership practice.
Factitious hyperkalemia in hematologic disorders

Hyperkalemia is a potentially lethal condition leading to fatal cardiac arrhythmias or asystole. After its urgent confirmation, immediate treatment is essential. Conversely, treatment of factitious hyperkalemia – where the measured potassium concentration does not reflect properly the actual potassium homeostasis of the patient – is unnecessary and may even have lethal consequences. Therefore, upon measuring elevated potassium concentration of a patient, distinction between true and factitious hyperkalemia is crucial. Hematologic disorders are often associated with distinct types of factitious hyperkalemia (pseudohyperkalemia or reverse pseudohyperkalemia). However, in spite of numerous reports, these conditions remain frequently unrecognized. In this letter, we present a case of thrombocytosis-associated pseudohyperkalemia to emphasize its clinical importance. Furthermore, we summarize distinct mechanisms behind factitious hyperkalemia in different hematologic conditions, overview their frequencies and propose a diagnostic algorithm to help their early recognition. Additionally, utility of ECG in recognizing factitious hyperkalemia is also discussed.
Enhanced In Vitro Formation and Antibiotic Resistance of Nonattached Pseudomonas aeruginosa Aggregates through Incorporation of Neutrophil Products

ABSTRACT Pseudomonas aeruginosa is a major pathogen in cystic fibrosis (CF) lung disease. Children with CF are routinely exposed to P. aeruginosa from the natural environment, and by adulthood, 80% of patients are chronically infected. P. aeruginosa in the CF airway exhibits a unique biofilm-like structure, where it grows in small clusters or aggregates of bacteria in association with abundant polymers of neutrophil-derived components F-actin and DNA, among other components. These aggregates differ substantially in size and appearance compared to surface-attached in vitro biofilm models classically utilized for studies but are believed to share properties of surface-attached biofilms, including antibiotic resistance. However, little is known about the formation and function of surface-independent modes of biofilm growth, how they might be eradicated, and quorum sensing communication. To address these issues, we developed a novel in vitro model of P. aeruginosa aggregates incorporating human neutrophil-derived products. Aggregates grown in vitro and those found in CF patients' sputum samples were morphologically similar; viable bacteria were distributed in small pockets throughout the aggregate. The lasA quorum sensing gene was differentially expressed in the presence of neutrophil products. Importantly, aggregates formed in the presence of neutrophils acquired resistance to tobramycin, which was lost when the aggregates were dispersed with DNase, and antagonism of tobramycin and azithromycin was observed. This novel yet simple in vitro system advances our ability to model infection of the CF airway and will be an important tool to study virulence and test alternative eradication strategies against P. aeruginosa.
Eliminating Anomalies in Learner Modeling Using Two-Partial Learner Model

learner interactions is not precise. In fact, existing e-learning systems only know the number of previewed pages precisely. They can deduce that how much the learner is mastered using some learner's characteristics such as time of doing exercises and the number of mistakes. But these deductions may be not precise. Because the time of doing exercises depends on learner's emotional states and environmental conditions. Thus we have introduced a new concept as two-partial learner model. Our proposed model divides learner model into two parts: Permanent Learner Model (PLM) and Temporary Learner Model (TLM). In the two-partial learner model, system's deductions are placed in the TLM at first. Then, system should validate accuracy of these deductions. Valid deductions are used in the updating of PLM for making them usable in other sessions. Otherwise, they should be ignored. Two-partial learner model is suitable for example-based educational systems. Because these systems are making deductions about the learner based on his/her interactions with the system.
Building Robota, a Mini-Humanoid Robot for the Rehabilitation of Children With Autism

The Robota project constructs a series of multiple-degrees-of-freedom, doll-shaped humanoid robots, whose physical features resemble those of a human baby. The Robota robots have been applied as assistive technologies in behavioral studies with low-functioning children with autism. These studies investigate the potential of using an imitator robot to assess children's imitation ability and to teach children simple coordinated behaviors. In this article, the authors review the recent technological developments that have made the Robota robots suitable for use with children with autism. They critically appraise the main outcomes of two sets of behavioral studies conducted with Robota and discuss how these results inform future development of the Robota robots and robots in general for the rehabilitation of children with complex developmental disabilities.
Integrated 0.9 V charge-control switching converter with self-biased current sensor

A charge-control non-inverting flyback converter that works in pseudo-continuous conduction mode is presented. Charge control is realized through the introduction of an integrated self-biased current sensor for fast response with a fully-matched structure for accuracy down to the mA range. The topology allows an output voltage of 1.2 V to be derived from a supply voltage of 1.5 V down to 0.9 V. The integrated converter is designed in a standard 0.18 /spl mu/ CMOS process. It switches at 500 kHz and exhibits excellent line-to-load transient response, with an efficiency of 91.3% at a load current of 200 mA.
Insights into the Academic Motivation of Tourism and Hospitality Students in a Research Methods Course

Consistent growth in tourism and hospitality international students in Australian universities makes it imperative higher education institutions remain vigilant in understanding diverse student cohorts to ensure the best possible learning environments are provided. To this end, the present study sought to investigate academic motivation among first year undergraduate students in a tourism and hospitality program in Australia. Survey participants consisted of 634 domestic Australian and Asian international students. Using the Academic Motivation Scale, this study identified the influence of cultural differences, assessment types and student status on academic performance. The findings of this study revealed that Asian students demonstrated higher intrinsic motivation to learn, while domestic Australian students were more extrinsically motivated. Implications for tourism management, tourism industry and education are discussed.
PSYCHOLINGUISTICS AS SCIENTIFIC ENCOUNTERS

The title of this paper, psycholinguistics äs scientific encounters, reflects what seems to be a persistent phenomenon in the history, äs well äs in the present state, of psycholinguistics. I thüik it is justified to say that psychology and linguistics make a couple whose marriage has not been totally happy. They are certainly a most unfitting pair and in their quarreis it has been claimed that one of the parties is not even of empirical substance. It is easy to imagine some problems in a marriage between a ghost and a traditionally most tangible figure such äs psychology. This peculiar relationship probably also accounts for some of the characteristics of psychoünguistic research that seem to have no actual counterparts in other areas of psychological research, even if there are analogical problems. I am thinking of the almost unidirectional influence of linguistic theory on the research problems formulated by psychologists. This approach caused an interest in what questions about language, whereas the natural domain of psychological inquiries should be how questions. The distinction between what and how questions intended here is the one that implies that you cannot ask questions about how language is acquired and used, before you know what language is (e.g. CHOMSKY, 1975). This viewpoint seemed to largely blindfold researchers to some crucial characteristics of language, namely its use äs a tool to reach certain aims. Of course, it is not at all self-evident that how questions and related questions about functions should be a legitimate undertaking for psycholinguistics if it uses some transformational-generative grammar äs its theoretical model. CHOMSKY (1975) has most astutely warned against this. But these warnings cannot undo the claims made by CHOMSKY (1968) about therelation between linguistics and psychol-
A Fast Goal Recognition Technique Based on Interaction Estimates

Goal Recognition is the task of inferring an actor's goals given some or all of the actor's observed actions. There is considerable interest in Goal Recognition for use in intelligent personal assistants, smart environments, intelligent tutoring systems, and monitoring user's needs. In much of this work, the actor's observed actions are compared against a generated library of plans. Recent work by Ramirez and Geffner makes use of AI planning to determine how closely a sequence of observed actions matches plans for each possible goal. For each goal, this is done by comparing the cost of a plan for that goal with the cost of a plan for that goal that includes the observed actions. This approach yields useful rankings, but is impractical for real-time goal recognition in large domains because of the computational expense of constructing plans for each possible goal. In this paper, we introduce an approach that propagates cost and interaction information in a plan graph, and uses this information to estimate goal probabilities. We show that this approach is much faster, but still yields high quality results.
Sleep Problems of Young Blind Children

This study investigated the sleep of 28 young blind and 22 sighted children aged 4–36 months whose parents completed the Sleep Habits Questionnaire. It found that the blind children had significantly more sleep problems related to bedtime and behaviors during the night than did the sighted children. In addition, the blind children went to sleep later at night, were awake longer during the night, and had less sleep time.
Pazopanib in Locally Advanced or Metastatic Renal Cell Carcinoma: Results of a Randomized Phase III Trial

Purpose Pazopanib is an oral angiogenesis inhibitor targeting vascular endothelial growth factor receptor, platelet-derived growth factor receptor, and c-Kit. This randomized, double-blind, placebo-controlled phase III study evaluated efficacy and safety of pazopanib monotherapy in treatment-naive and cytokine-pretreated patients with advanced renal cell carcinoma (RCC). Patients and Methods Adult patients with measurable, locally advanced, and/or metastatic RCC were randomly assigned 2:1 to receive oral pazopanib or placebo. The primary end point was progression-free survival (PFS). Secondary end points included overall survival, tumor response rate (Response Evaluation Criteria in Solid Tumors), and safety. Radiographic assessments of tumors were independently reviewed. Results Of 435 patients enrolled, 233 were treatment naive (54%) and 202 were cytokine pretreated (46%). PFS was significantly prolonged with pazopanib compared with placebo in the overall study population (median, PFS 9.2 v 4.2 months; hazard ratio [HR], 0.46; 95% CI, 0.34 to 0.62; P < .0001), the treatment-naive subpopulation (median PFS 11.1 v 2.8 months; HR, 0.40; 95% CI, 0.27 to 0.60; P < .0001), and the cytokine-pretreated subpopulation (median PFS, 7.4 v 4.2 months; HR, 0.54; 95% CI, 0.35 to 0.84; P < .001). The objective response rate was 30% with pazopanib compared with 3% with placebo (P < .001). The median duration of response was longer than 1 year. The most common adverse events were diarrhea, hypertension, hair color changes, nausea, anorexia, and vomiting. There was no evidence of clinically important differences in quality of life for pazopanib versus placebo. Conclusion Pazopanib demonstrated significant improvement in PFS and tumor response compared with placebo in treatment-naive and cytokine-pretreated patients with advanced and/or metastatic RCC.
Development of a Three-to-Five-Phase Indirect Matrix Converter With Carrier-Based PWM Based on Space-Vector Modulation Analysis

This paper proposes an indirect matrix converter (IMC) topology to supply a five-phase load directly from three-phase ac power sources without bulky electrolytic capacitors and explains its operating principle. Using the emerging topology, which combines the five-leg inverter into the rectifier stage of the conventional IMC, the three-to-five-phase IMC topology reduces the number of power switches and results in a simpler commutation compared with the conventional three-to-five-phase direct matrix converter. In addition, a simple approach to realize the carrier-based pulsewidth modulation (CBPWM) method for a three-to-five-phase IMC is presented, and the proposed CBPWM method is analyzed based on the space-vector approach. As a result, the IMC with the proposed CBPWM method can be more easily implemented compared with IMCs with the space-vector PWM method. A three-to-five-phase IMC control platform is realized by coordinating a TMS320F28335 DSP (Texas Instruments) with an EPM7128SLC84-15 field-programmable gate array (Altera). The simulation and experimental results are provided to verify the effectiveness of the CBPWM strategy.
Testing a cyclical model of communicative openness in relationship development: Two longitudinal studies

This paper reports the results of two longitudinal studies of openness‐closedness cycling in relationship development based upon a model by Altman, Vinsel, and Brown (1981). Study 1 consists of behavioral observations of interactions among acquainting dyads over four weeks. Study 2 consists of self‐reported measures of subjects’ openness, openness of other, communication satisfaction, and relationship satisfaction in intact relationships over ten weeks. Fourier Analyses of the time series were conducted and meta‐analyses were conducted to test the hypotheses. Both studies strongly support a cyclical model. There appear to be short cycles recurring within conversations superimposed over larger cycles across conversations. The results also suggest that people match and time the amplitude and frequency of their own cycling behavior to coincide with that of their partner. Study 2 found that the cycles of perceived openness coincide with fluctuations in communication satisfaction and that deteriorating relatio.
