Optimal resource planning for maintenance of distribution networks

Yearly resource planning for distribution grid operation is often based on average values of the past. However, a more detailed model of distribution networks is indispensable if grid operators´ decisions regarding operation and structure of the network have to be evaluated. In addition, scheduling of human and material resources have to be taken into account to compare different strategies of network operation and its influence on costs.
Disruption of the Raf-1-Hsp90 Molecular Complex Results in Destabilization of Raf-1 and Loss of Raf-1-Ras Association (*)

Cytosolic Raf-1 exists in a high molecular weight complex with the heat shock protein Hsp90, the purpose of which is unknown. The benzoquinone ansamycin, geldanamycin, specifically binds to Hsp90 and disrupts certain multimolecular complexes containing this protein. Using this drug, we are able to demonstrate rapid dissociation of both Raf-1-Hsp90 and Raf-1-Ras multimolecular complexes, concomitant with a markedly decreased half-life of the Raf-1 protein. Continued disruption of the Raf-1-Hsp90 complex results in apparent loss of Raf-1 protein from the cell, although Raf-1 synthesis is actually increased. Prevention of Raf-1-Hsp90 complex formation interferes with trafficking of newly synthesized Raf-1 from cytosol to plasma membrane. These data indicate that association with Hsp90 is essential for both Raf-1 protein stability and its proper localization in the cell.
Text Opinion Mining to Analyze News for Stock Market Prediction

This is a known fact that news and stock prices are closely related and news usually has a great influence on stock market investment. There have been many researches aimed at identifying that relationship or predicting stock market movements using news analysis. Recently, massive news tests, called unstructured big-data, have been used to predict stock price. In this paper, we introduce a method of mining text opinions to analyze Korean language news in order to predict rises and falls on the KOSPI (Korea Composite Stock Price Index). Our method consists of carrying out the NLP (Natural Language Processing) of news, describing its features, categorizing and extracting the sentiments and opinions expressed by the writers. The method then identifies the correlation between news and stock market fluctuations. In our experiment, we show that our method can be used to understand unstructured big-data, and we also reveal that news’ sentiment can be used in predicting stock price fluctuations, whether up or down. The algorithm extracted experiments can be used to make predictions about stock market movements .
A tale of two corporations: Managing uncertainty during organizational change

Ineffective strategies of communicating about organizational change (e.g., corporate restructuring, mergers, downsizing) are earmarked by the presence of pervasive rumors that flourish in a climate of uncertainty. Using 15 structured field interviews with management and public relations personnel from multinational corporations, this article posits that successful programs of change communication hinge upon the proper management of uncertainty associated with change. Two detailed case studies are highlighted as opposing illustrations of change communication tactics that succeeded and failed. Effective change communication campaigns tend to reveal rather than conceal, reduce uncertainty through collective planning, and proactively establish and maintain trust. 1
Throughput Estimation Based Distributed Base Station Selection in Heterogeneous Networks

Small cells are considered an emerging technology for increasing the potential capacity of cellular networks. However, as the density of infrastructure increases, users have many choices for connection, and therefore, selecting an appropriate base station (BS) becomes an important issue. This study aims to provide an improved user association rule, where each user autonomously chooses the best among all the BSs in the vicinity, while considering their congestion levels. As the first step, an optimization problem is formulated, which emphasizes both the time-varying nature of the wireless channel and fairness among users. On the basis of this formulation, the influence of a specific handover event on system performance is investigated, and then, two versions of the handover frameworks are developed. Simulation results show that the proposed algorithms increase the throughput of every user in the network by 2.8-12% compared to the best conventional scheme. Furthermore, these schemes especially enhance the performance of users having low service quality by 5.0-85%, through efficient utilization of the pre-installed infrastructures.
Endoglin inhibition leads to intussusceptive angiogenesis via activation of factors related to COUP-TFII signaling pathway

Angiogenesis is a highly coordinated, extremely complex process orchestrated by multiple signaling molecules and blood flow conditions. While sprouting mode of angiogenesis is very well investigated, the molecular mechanisms underlying intussusception, the second mode of angiogenesis, remain largely unclear. In the current study two molecules involved in vascular growth and differentiation, namely endoglin (ENG/CD105) and chicken ovalbumin upstream promoter transcription factor II (COUP-TFII) were examined to unravel their specific roles in angiogenesis. Down- respectively up-regulation of both molecules tightly correlates with intussusceptive microvascular growth. Upon ENG inhibition in chicken embryo model, formation of irregular capillary meshwork accompanied by increased expression of COUP-TFII could be observed. This dynamic expression pattern of ENG and COUP-TFII during vascular development and remodeling correlated with formation of pillars and progression of intussusceptive angiogenesis. Similar findings could be observed in mammalian model of acute rat Thy1.1 glomerulonephritis, which was induced by intravenous injection of anti-Thy1 antibody and has shown upregulation of COUP-TFII in initial phase of intussusception, while ENG expression was not disturbed compared to the controls but decreased over the time of pillar formation. In this study, we have shown that ENG inhibition and at the same time up-regulation of COUP-TFII expression promotes intussusceptive angiogenesis.
Laser-Assisted Frenectomy Using 980nm Diode Laser

A frenum is a fold of tissue or muscle connecting the lips, cheek or tongue to the jawbone. Their high attachment may cause orthodontic problem (Central diastima), prosthodontic problems (Poor retention of denture), periodontic problems (gingival recession and inflammation) and speech problem (tongue tied in ligual frenum). A frenectomy is the removal of one of these folds of tissue and it is a common procedure in the specialty of maxillofacial surgery. Laser-assisted frenectomy is a much more comfortable for the patient because it means that no scalpel or stitches are required. This clinical study was carried out at department of Maxillofacial Surgery, Ramadi Teaching Hospital; 25 patients including 16 (64%) male and 9 (36%) female with age range from 3 months to 18 years old with mean age 6.5 years old. Chirolas 20W diode laser emitting at 980 nm; the laser is delivered through a fiber optic 400 μm. Beam profile is a single-mode Gaussian (TEM 00 ) , with a spot size (0.9 mm) was used to performed laser-assisted frenectomy. Our preliminary clinical findings include sufficient hemostasis, coagulation properties and precise incision margin with all of the surgical procedure. The postoperative advantages, i.e., lack of swelling, bleeding, pain or, scar tissue formation, the good wound healing and overall satisfaction were observed in the clinical application of laser-assisted frenectomy. The clinical application of the diode (980 nm) laser in oral and maxillofacial surgical procedures proved to be of beneficial effect for daily practice, it can be considered practical, effective, easy to used, offers a safe, acceptable, and impressive alternative for conventional techniques of frenectomy.
The Corporate Response to the 2003 Dividend Tax Cut

In 2003, the tax rate on dividends was reduced from 35% to 15%. The crafters of the tax reduction and the popular press have suggested that the corporate response to the tax cut was immediate, and that firms began increasing dividend payments as a result of the lower tax rate soon after the law was passed. We compare 2003 and 2004 dividend tax policy to those of the previous four years for firms in the S&P 500 and find mixed evidence of these firms changing their tax policy in the aggregate. Firms with high earnings and low investment opportunities were the most likely to increase dividends in response to the tax change.
Low phonon energy, Nd:LaF/sub 3/ channel waveguide lasers fabricated by molecular beam epitaxy

We report the first fabrication and laser operation of channel waveguides based on LaF/sub 3/ planar thin films grown by molecular beam epitaxy. To our knowledge, this is the lowest phonon energy dielectric material to have shown guided-wave laser operation to date. A full characterization, in terms of spectroscopy, laser results, and propagation losses, is given for the planar thin films upon which the channel waveguides are based. Two channel-fabrication methods are then described, the first involves ion milling and the second takes the novel approach of using a photo-definable polymer overlay. Laser operation in Nd-doped samples is demonstrated at 1.06, 1.05, and 1.3 /spl mu/m, and the potential for mid-infrared laser sources based on such guides is discussed.

Measuring the Impact of Eminent Domain Partial Takings: A Behavioral Approach

This study uses a behavioral approach to measure the impact of a partial eminent domain land taking (which affects easement rights and causes proximity damage) on residential property values. Existing appraisal methods are not suited to handle this type of unique valuation impact determination, yet diminution must be determined by the courts to establish proper i§just compensationi¨. To accomplish the quantification of damages, an experimental design is implemented that allows the market to voice its opinion of valuation impact through a mechanism other than direct comparable sales. Moreover, this behavioral methodology can and should be used in a number of additional real estate valuation applications.
Checkmark Grading and the Quarter System

For several years, I, too, had been searching for a better way to handle student papers; the traditional, one-shot method of &dquo;you make the mistakes and I’ll correct them&dquo; simply was no working any longer. The brilliance of the Freeman-Hatch system, as I saw it, was that it cut through all the destructive and depressing red tape of older grading techniques for both students and teachers alike. But would it work for me?
The efficiency of corrective exercise interventions on thoracic hyper-kyphosis angle.

BACKGROUND AND OBJECTIVE Corrective exercise interventions are often utilized to manage subjects with thoracic hyper-kyphosis, yet the quality of evidence that supports their efficiency is lacking. In this study, the efficacy of local and comprehensive corrective exercise programs (LCEP and CCEP) on kyphosis angle was evaluated. MATERIAL AND METHOD A prospective, randomised controlled design was used in the present study. Sixty patients with postural hyper-kyphosis deformity (⩾ 42°) entered the study for 12 weeks. Subjects were randomly assigned to a LCEP (n=20), CCEP (n=20), or Control groups (n=20). Pre- and post-participation levels of kyphosis angle were measured by flexicurve ruler. RESULTS Both the LCEP and CCEP groups demonstrated statistically significant reductions in thoracic kyphosis angle compared to the control group (p=0.001). Furthermore, based on Cohen's d-value, the efficiency of CCEP was larger than LCEP. CONCLUSIONS Considering the extremely large effect size of the CCEP, we recommend that this program be used in the correction of postural hyper-kyphosis deformity in future.
A Bayesian Network Based on the Differentiated Pedagogy to Generate Learning Object According to FSLSM

In this paper we propose a model that generates learning objects in an adaptive learning system according to the Felder-Silverman learning styles, based on the Bayesian networks and taking into consideration the recommendations of the differentiated pedagogy which requires creating multiple versions of the same learning object. The proposed model includes also correcting the non-learning paths which is the main reason behind the choice of versioning the learning objects.
The aging of elastic and muscular arteries: a comparison of diabetic and nondiabetic subjects.

OBJECTIVE To compare age-related changes in the mechanical properties of different arterial segments in normal volunteers and subjects with type 2 diabetes. RESEARCH DESIGN AND METHODS In 169 subjects (diabetic n = 57 and nondiabetic n = 112), we assessed the mechanical properties of three arterial segments of differing wall composition. Pulse wave velocity (PWV) was measured noninvasively in a thoraco-abdominal segment (carotid femoral PWV [PWV(cf)]), in an upper limb muscular artery (carotid radial PWV [PWV(cr)]), and from the aorta to the finger (PWV from the aorta to the finger [PWV(fin)]). Central aortic compliance (CAC) was also measured. RESULTS Average CAC was lower (0.662 vs. 0.850, P < 0.05) and all measures of PWV tended to be faster in diabetic subjects despite the fact that they were, on average, 10 years younger. However, these measures were not related to age in diabetic subjects. After correcting for blood pressure, only PWV(cf) was associated with age in nondiabetic subjects (P < 0.001). Expressing results as ratios of nonelastic to elastic arterial segments (i.e., PWV(cr)-to-PWV(cf) and PWV(fin)-to-PWV(cf)) improved the relationship with age. Both PWV(cr)-to-PWV(cf) and PWV(fin)-to-PWV(cf) were significantly associated with age in nondiabetic subjects (r = -0.59, P < 0.001; r = -0.57, P < 0.001) but not in diabetic subjects (r = -0.15, P = 0.302; r = -0.24, P = 0.129). Multivariate analysis showed that the ratios were not associated with systolic blood pressure. CONCLUSIONS There are significant differences in the rate of age-related decline in vascular stiffness in elastic arteries of nondiabetic compared with diabetic arteries. Diabetic arteries appear to age at an accelerated rate at an earlier age and then reach a functional plateau.
24-line multiwavelength operation of erbium-doped fiber-ring laser

Simultaneous lasing at up to 24 wavelengths is demonstrated in an erbium-doped fiber-ring laser using a simple design. This result is achieved using a low-loss cavity, controlled polarization evolution and liquid nitrogen cooling to enhance spectral hole-burning, polarization hole-burning, and polarization selectivity. The design does not include any wavelength-selective components; instead, it utilizes wavelength selectivity provided by polarization evolution in the cavity. The amplitude variation between emission peaks is less than 3 dB over a 17-nm spectral range. A narrow linewidth of 0.15 nm, dense line spacing of 1.1 nm, and a good signal-to-noise ratio of more than 30 dB are achieved over most of the erbium bandwidth. The comb spectrum location and width are adjustable by changing and adjusting cavity components.
Design Optimization of NEMS Switches for Suspended-Gate Single-Electron Transistor Applications

The operation of nanoelectromechanical switches is investigated through simulation. A simple methodology based on a 1-D lumped model taking account of the Casimir effect is first proposed to determine a low-voltage actuation window for conventional cantilevers. Results show good agreement with 3-D simulation and prove to be helpful for systematic design. The conventional cantilever shape is then optimized to a cross-like design that is fully studied in a 3-D environment. Static and dynamic behaviors as well as effect of the oxide layer thickness are investigated with a view to suspended-gate single-electron transistor applications. The proposed structure successfully combines low actuation voltage and low power consumption, and it is shown that the switching speed is the limiting factor for the considered applications.
A Multi-Layered Control Approach for Self-Adaptation in Automotive Embedded Systems

We present an approach for self-adaptation in automotive embedded systems using a hierarchical, multi-layered control approach. We model automotive systems as a set of constraints and define a hierarchy of control loops based on different criteria. Adaptations are performed at first locally on a lower layer of the architecture. If this fails due to the restricted scope of the control cycle, the next higher layer is in charge of finding a suitable adaptation. We compare different options regarding responsibility split in multilayered control in a self-healing scenario with a setup adopted from automotive in-vehicle networks. We show that a multi-layer control approach has clear performance benefits over a central control, even though all layers work on the same set of constraints. Furthermore, we show that a responsibility split with respect to network topology is preferable over a functional split.
The Internationalisation of Small to Medium-Sized Retail Companies: Towards A Conceptual Framework

The internationalisation of large multinational retailers is well documented and much research attention has been given to their processes, motives and strategies for expansion. However, a successful international retailer does not necessarily have to be a large retailer. Dynamic smallerretailers with strong concepts, formats and products have shown themselves capable of rapid international growth. To date there has been a distinct lack of research on the internationalisation of small to medium-sized companies (SMEs) operating in the retail sector. Any discussion of SME internationalisationwithin the retail industry should recognise that research on large multinational corporations is not directly transferable to small and medium-sized firms who by their very nature and characteristics embrace a very different set of opportunities in the international market. To address thisgap in research, this paper draws upon broader established international SME and entrepreneurship literatures to provide a framework for examining some of the key aspects of the internationalisation of retail SMEs.
Resistance of Rabbits and Guinea Pigs to the Diabetogenic Effect of Streptozotocin

Streptozotocin is an antibiotic with antitumor properties. It has been reported to be diabetogenic in dogs, monkeys, hamsters, rats, and mice. Rabbits and guinea pigs were found to be resistant to the diabetogenic action of streptozotocin. Resistance in these species was not related to impaired ability to maintain adequate serum concentrations of the drug. Streptozotocin incubated with rabbit serum and liver homogenate maintained its diabelogenic properties when injected in the rat. Liver and pancreas homogenates of the resistant species did not metabolize the drug in vitro as determined spectrophotometrically. It is postulated that the diabetogenic action of streptozotocin may be related to its ability to impair NAD synthesis. It is postulated that the drug apparently blocks the synthesis of NAD from nicotinamide but has no effect on the synthesis of NAD from nicotinic acid, the pathway which may be preferentially employed by rabbits and guinea pigs.
Value creation processes and value outcomes in marketing theory

The present article alleviates the often-cited ambiguity of the value concept by proposing that value research consists of two main streams: value creation processes and value outcomes. The prior considers the parties, activities, and resources involved in value creation, whereas the latter explains the value outcomes customers perceive. Furthermore, the article investigates the value approach offered by the Service-Dominant logic, which proposes that value is co-created by firms and customers, and that beneficiaries determine the value [outcomes] (Vargo and Lusch, 2008). Finally, the article discusses how value creation processes and value outcomes might be interlinked, and creates a number of propositions to this end. It is in particular proposed that experiences offer a shared platform for investigating value creation processes and value outcomes.
An empirical study of relationship quality in a service setting: a Chinese case

Purpose – The paper's aim is to investigate the antecedents and outcomes of the relationship between providers and consumers of a “high‐credence” service, in Hong Kong.Design/methodology/approach – A model of antecedents and outcomes was constructed. Relationship quality was conceptualized as the degree of trust in and satisfaction with the service provider. Data collected in face‐to‐face interviews with over 200 clients of 12 health‐care clinics questionnaire survey were analyzed by confirmatory factor analysis and structural equation modelling, to test six hypotheses.Findings – The findings support the hypotheses and show that the service providers' expertise, empathy, likeability, and communication effectiveness significantly influenced relationship quality, leading in turn to the likelihood of re‐patronage and word‐of‐mouth recommendation.Research limitations/implications – The study suggests ways in which service providers can improve the quality of the customer relationship. Findings can be generali.
High-Fidelity Avatar Eye-Representation

In collaborative virtual environments, the visual representation of avatars has been shown to be an important determinant of participant behaviour and response. We explored the influence of varying conditions of eye-representation in our high-fidelity avatar by measuring how accurately people can identify the avatar's point-of- regard (direction of gaze), together with subjective authenticity assessments of the avatar's behaviour and visual representation. The first of two variables investigated was socket-deformation, which is to say that our avatar's eyelids, eyebrows and surrounding areas morphed realistically depending on eye-rotation. The second was vergence of our avatar's eyes to the exact point-of-regard. Our results suggest that the two variables significantly influence the accuracy of point-of-regard identification. This accuracy is highly dependent on the combination of viewing-angle and the point-of-regard itself. We found that socket-deformation in particular has a highly positive impact on the perceived authenticity of our avatar's overall appearance, and when judging just the eyes. However, despite favourable subjective ratings, overall performance during the point-of-regard identification task was actually worse with the highest quality avatar. This provides more evidence that as we move forward to using higher fidelity avatars, there will be a tradeoff between supporting realism of representation and supporting the actual communicative task.
