Influence of External Factors on Self-healing Capacitor Temperature Field Distribution and Its Validation

Temperature field simulation for self-healing power capacitor makes sense to the capacitor optimization and improvement of capacitor’s rated voltage and capacity. On the basis of reasonable simplifications and assumptions for capacitor structure, a 3-D temperature field numerical simulation model for a self-healing power capacitor is formulated in Fluent 15.0. The ambient temperature is set to 55 °C, and the applied voltage is ac 400 V. The temperature distributions of the shell and core of the self-healing capacitor are obtained. The results reveal that the temperature of the core is 2 °C–3 °C higher than that of the shell. The highest temperature of the shell locates on the large side surface, and the temperature of the large side surface is higher than that of the small side surface. To validate the above simulation, a self-healing capacitor is manufactured and thermal resistance sensors are used to measure the temperature in the thermal stability test. The simulation is validated by the experiment. Finally, the influences of the ambient temperature and applied voltage on the temperature rise are investigated. This paper can be taken a reference to the self-healing capacitor operation, maintenance, and even the optimization of its internal structure and material.
A New Adaptive Merging and Growing Algorithm for Designing Artificial Neural Networks

This paper presents a new algorithm, called adaptive merging and growing algorithm (AMGA), in designing artificial neural networks (ANNs). This algorithm merges and adds hidden neurons during the training process of ANNs. The merge operation introduced in AMGA is a kind of a mixed mode operation, which is equivalent to pruning two neurons and adding one neuron. Unlike most previous studies, AMGA puts emphasis on autonomous functioning in the design process of ANNs. This is the main reason why AMGA uses an adaptive not a predefined fixed strategy in designing ANNs. The adaptive strategy merges or adds hidden neurons based on the learning ability of hidden neurons or the training progress of ANNs. In order to reduce the amount of retraining after modifying ANN architectures, AMGA prunes hidden neurons by merging correlated hidden neurons and adds hidden neurons by splitting existing hidden neurons. The proposed AMGA has been tested on a number of benchmark problems in machine learning and ANNs, including breast cancer, Australian credit card assessment, and diabetes, gene, glass, heart, iris, and thyroid problems. The experimental results show that AMGA can design compact ANN architectures with good generalization ability compared to other algorithms.
Ultrawideband microwave breast cancer detection: a detection-theoretic approach using the generalized likelihood ratio test

Microwave imaging has been suggested as a promising modality for early-stage breast cancer detection. In this paper, we propose a statistical microwave imaging technique wherein a set of generalized likelihood ratio tests (GLRT) is applied to microwave backscatter data to determine the presence and location of strong scatterers such as malignant tumors in the breast. The GLRT is formulated assuming that the backscatter data is Gaussian distributed with known covariance matrix. We describe the method for estimating this covariance matrix offline and formulating a GLRT for several heterogeneous two-dimensional (2-D) numerical breast phantoms, several three-dimensional (3-D) experimental breast phantoms, and a 3-D numerical breast phantom with a realistic half-ellipsoid shape. Using the GLRT with the estimated covariance matrix and a threshold chosen to constrain the false discovery rate (FDR) of the image, we show the capability to detect and localize small (<0.6 cm) tumors in our numerical and experimental breast phantoms even when the dielectric contrast of the malignant-to-normal tissue is below 2:1.
A Novel Inhibitor of DNA Polymerase β Enhances the Ability of Temozolomide to Impair the Growth of Colon Cancer Cells

The recent emerging concept to sensitize cancer cells to DNA-alkylating drugs is by inhibiting various proteins in the base excision repair (BER) pathway. In the present study, we used structure-based molecular docking of DNA polymerase β (Pol-β) and identified a potent small molecular weight inhibitor, NSC-666715. We determined the specificity of this small molecular weight inhibitor for Pol-β by using in vitro activities of APE1, Fen1, DNA ligase I, and Pol-β–directed single-nucleotide and long-patch BER. The binding specificity of NSC-666715 with Pol-β was also determined by using fluorescence anisotropy. The effect of NSC-666715 on the cytotoxicity of the DNA-alkylating drug temozolomide (TMZ) to colon cancer cells was determined by in vitro clonogenic and in vivo xenograft assays. The reduction in tumor growth was higher in the combination treatment relative to untreated or monotherapy treatment. NSC-666715 showed a high specificity for blocking Pol-β activity. It blocked Pol-β–directed single-nucleotide and long-patch BER without affecting the activity of APE1, Fen1, and DNA ligase I. Fluorescence anisotropy data suggested that NSC-666715 directly and specifically interacts with Pol-β and interferes with binding to damaged DNA. NSC-666715 drastically induces the sensitivity of TMZ to colon cancer cells both in in vitro and in vivo assays. The results further suggest that the disruption of BER by NSC-666715 negates its contribution to drug resistance and bypasses other resistance factors, such as mismatch repair defects. Our findings provide the “proof-of-concept” for the development of highly specific and thus safer structure-based inhibitors for the prevention of tumor progression and/or treatment of colorectal cancer.

Vantage Point and Visual Imagery: Effects on Recall in Younger and Older Adults

The current study explored the influence of priming vantage point at retrieval on the recall of younger and older adults, in addition to the effects of visualization ability on recall. Based on McIsaac and Eich’s (2002) findings of the effects on younger adults’ recall, it was hypothesized that recollections would be more likely to include certain features when retrieved through the field vantage point (FVP) than through the observer vantage point (OVP) and vice-versa. Additionally, it was expected that older adults would recall more detailed memories from the OVP than from the FVP. Finally, it was hypothesized that visualization ability would influence memory vividness and that it would be more influential in older adults than in younger adults. The experiment was conducted across two sessions. In Session 1, participants completed a visual imagery assessment, and memories were created in the laboratory with younger (n = 20; 18-21 years old) and older (n = 18; 63-88 years old) adults through the completion of two activities. In Session 2, participants recalled the activities from either the FVP or the OVP. Participants’ recollections were coded for various memory characteristics, which acted as dependent variables in analyses. A significant interaction effect (p = .003) between age and vantage point was found on the characteristic of psychological state, such that older adults referred to their psychological state in FVP memories more than in OVP memories (p = .002), while younger adults demonstrated no significant difference. Imagery ability significantly predicted several aspects of participants’ subjective recall experience. Overall, the results indicate that retrieval vantage point does not change the content of one’s recollections on most measures for either younger or older adults and that visual mental imagery ability predicts several aspects of one’s recall experience.
Single-dimension software pipelining for multi-dimensional loops

Traditionally, software pipelining is applied either to the innermost loop of a given loop nest or from the innermost loop to outer loops. We propose a three-step approach, called single-dimension software pipelining (SSP), to software pipeline a loop nest at an arbitrary loop level. The first step identifies the most profitable loop level for software pipelining in terms of initiation rate or data reuse potential. The second step simplifies the multidimensional data-dependence graph (DDG) into a 1-dimensional DDG and constructs a 1-dimensional schedule for the selected loop level. The third step derives a simple mapping function which specifies the schedule time for the operations of the multidimensional loop, based on the 1-dimensional schedule. We prove that the SSP method is correct and at least as efficient as other modulo scheduling methods. We establish the feasibility and correctness of our approach by implementing it on the IA-64 architecture. Experimental results on a small number of loops show significant performance improvements over existing modulo scheduling methods that software pipeline a loop nest from the innermost loop.

We report on efficient (-7-dB fiber-to-fiber), wide-band (over 70 nm), tunable, and excess-noise-free mid-span spectral inverters based on cascaded second-order nonlinearities in periodically poled LiNbO/sub 3/ waveguides. We demonstrate their performance in a 4/spl times/10 Gb/s transmission over 150 km of standard single-mode fiber.
Prognostic value of osteopontin in patients treated with primary radiotherapy for head and neck cancer.

BACKGROUND The prognostic value of tumor osteopontin (OPN) in patients with squamous-cell head and neck cancer (SCHNC) was investigated. MATERIALS AND METHODS OPN expression was assessed by immunohistochemical methods in 50 patients, who were treated with primary radiotherapy (RT) for locally advanced SCHNC. The effects of OPN on clinical parameters, local-regional control after RT and metastasis-free survival, was assessed. RESULTS The rate of OPN expression in tumor tissue was 76%. OPN positive cases had lower Hb levels (p=0.088). Mean time to local recurrence was 53.8 months (SE 3.9) in OPN-negative cases and 39.1 months (SE 4.7) in OPN-positive cases (p=0.047). OPN increased the risk of local recurrence 5.9 times (p=0.085). It had no effect on metastasis-free (p=0.116) or overall survival (p=0.123). OPN was positive in 12 of 19 cases that developed grade 3-4 acute radiation dermatitis (p=0.096). CONCLUSIONS OPN expression is associated with an increase in local recurrence in patients who were treated with primary RT for locally advanced SCHNC.
Plants of the Genus Zingiber as a Source of Bioactive Phytochemicals: From Tradition to Pharmacy

Plants of the genus Zingiber (Family Zingiberaceae) are widely used throughout the world as food and medicinal plants. They represent very popular herbal remedies in various traditional healing systems; in particular, rhizome of Zingiber spp. plants has a long history of ethnobotanical uses because of a plethora of curative properties. Antimicrobial activity of rhizome essential oil has been extensively confirmed in vitro and attributed to its chemical components, mainly consisting of monoterpene and sesquiterpene hydrocarbons such as α-zingiberene, ar-curcumene, β-bisabolene and β-sesquiphellandrene. In addition, gingerols have been identified as the major active components in the fresh rhizome, whereas shogaols, dehydrated gingerol derivatives, are the predominant pungent constituents in dried rhizome. Zingiber spp. may thus represent a promising and innovative source of natural alternatives to chemical food preservatives. This approach would meet the increasing concern of consumers aware of the potential health risks associated with the conventional antimicrobial agents in food. This narrative review aims at providing a literature overview on Zingiber spp. plants, their cultivation, traditional uses, phytochemical constituents and biological activities.
Image Compression Using PCA and Improved Technique with MLP Neural Network

Computer images consist of large data and hence require more space to store in the memory. The compressed image requires less storing space of memory and less time to transmit. In this paper, feed forward back propagation neural network method with PCA technique is used for image compression. It is found that the results using PCA techniques are not satisfactory. To improve these results author suggest another technique which has better results. The Artificial Neural Network (ANN) used in these technique is trained by considering the different numbers of hidden neurons, epoch and reconstructed image compared with original image.
The Preparation of Preservice Elementary Educators in Understanding and Applying the Terms, Concepts, and Practices Associated with Response to Intervention in Early Reading Contexts

The purpose of the present inquiry was to identify how thoroughly degree-granting institutions in our state prepare elementary educators to serve students’ literacy needs from a response to intervention perspective. The first investigator collected syllabi via a Freedom of Information request made to the state's Department of Higher Education, which had gathered syllabi in relation to a separate inquiry. Results indicated that preservice elementary educators are not routinely being prepared to understand key terms, concepts, and practices associated with response to intervention in early reading contexts. Implications for school leaders, district administrators, and higher education faculty are reviewed.
The Effects of Ethnicity and Gender on Facilitating Intrinsic Motivation during Leisure with a Close Friend

Abstract This study empirically tests Walker, Deng, and Dieser's (2005) proposition that ethnicity affects which factors most facilitate people's feelings of intrinsic motivation during leisure; and it extends their work by also examining the effect of gender on these facilitators. A trilingual telephone survey asked Chinese/Canadian (N = 298) and British/Canadian (N = 321) participants to identify a leisure activity they found interesting and enjoyable (i.e., intrinsically motivated) when they were with a close friend. Participants then reported how they perceived varying six facilitators—autonomy/ personal choice, autonomy/mutual choice, relatedness, competence, effort, and role fulfillment—would affect their intrinsic motivation during this leisure situation. Statistical analyses indicated that five of the six facilitators differed by ethnicity, or gender, or both. Study findings are discussed, and theoretical and practical implications are described.
Mirror symmetry for weighted projective planes and their noncommutative deformations

We study the derived categories of coherent sheaves of weighted projective spaces and their noncommutative deformations, and the derived categories of Lagrangian vanishing cycles of their mirror Landau-Ginzburg models. In particular, we show that the derived category of coherent sheaves (B-branes) on the weighted projective plane $\CP^2(a,b,c)$ is equivalent to the derived category of vanishing cycles (A-branes) on the affine hypersurface $X=\{x^ay^bz^c=1\}\subset (\C^*)^3$ equipped with an exact symplectic form and the superpotential $W=x+y+z$. Hence, the homological mirror symmetry conjecture holds for weighted projective planes. Moreover, we also show that this mirror correspondence between derived categories can be extended to toric noncommutative deformations of $\CP^2(a,b,c)$ where B-branes are concerned, and their mirror counterparts, non-exact deformations of the symplectic structure of $X$ where A-branes are concerned. We also obtain similar results for other examples such as weighted projective lines or Hirzebruch surfaces.
An Investigation of the Success for All Reading Program.

This paper is based on a study of the Success for All (SFA) reading program at two Mississippi elementary schools. In particular, the study investigated whether SFA was being implemented as advocated by its developers, students' reading scores on standardized achievement tests, how the program was monitored, attitudes toward reading, and what key informants said about the program. Mixed methods--qualitative and quantitative--were used to collect, analyze, and interpret data. Document review, field observation, surveys, and interviews were used to collect data. Findings revealed that adherence to the program's protocols, as designed by the developers, was only partial. Standardized achievement test scores of children in some grades increased, while the scores of children in other grades decreased. Since SFA's prescriptive nature controls teaching methods, children's learning experiences, and curriculum content, it was not surprising to find that teachers were less positive in their attitudes toward the program than were students and parents.

Lung Transplantation in Children

ObjectiveTo report the authors’ experience with pediatric lung transplantation (LTX) to provide an overview of patients selected for this procedure and their outcomes. Summary Background DataPediatric LTX differs from adults in many ways, including recipient size, indications, posttransplant care, and rehabilitation. MethodsTwo hundred seven isolated lung transplants on 190 children under the age of 18 years were performed from 1990 to the present. This represents the single largest series of lung transplants in children in the world. Thirty-two patients were less than 1 year of age, 22 were 1 to 5 years of age, 32 were 5 to 10 years of age, and 121 were 10 to 18 years old. The groups by major diagnostic category were cystic fibrosis (n = 89), pulmonary vascular disease (n = 44), bronchiolitis obliterans (n = 21), pulmonary alveolar proteinosis (n = 12), pulmonary fibrosis (n = 15), and other (n = 26). The average age at the time of transplant was 9.5 ± 5.9 years (range 36 days to 18 years). ResultsSurvival by Kaplan-Meier analysis was 77% at 1 year, 62% at 3 years, and 55% at 5 years. There was no significant difference in survival according to primary diagnosis leading to LTX or age at LTX. There were 25 early (<60 days) and 61 late deaths. The most common cause of early deaths was graft failure (13/25, 52%). The most common causes of late death were bronchiolitis obliterans (35/61, 57%), infection (13/61, 21%), and posttransplant malignancies (11/61, 18%). No patient died of acute rejection. In those surviving greater than 3 months (mean follow-up 3.5 years, range 3 months to 11 years), the overall rate of occurrence of bronchiolitis obliterans was 46% (80/175) and the overall incidence of posttransplant malignancies was 24/175 (14%). Major risk factors for the development of bronchiolitis obliterans were age older than 3 years, more than two episodes of acute rejection, and organ ischemic time longer than 180 minutes. ConclusionsIn children, LTX is a high-risk but viable treatment for end-stage pulmonary parenchymal and vascular disease. The major hurdle to overcome in long-term survival is bronchiolitis obliterans.
School Counselors' Time: Where Does It Go?.

"Do school counselors really have time to activities. " Since the beginning of school do any counseling? " is asked frequently counseling, the role and function of the by prospective counseling students. school counselor have been examined, Parents, teachers, students, and adcritiqued, debated, and reexamined ministrators are heard to comment that (Podemski & Childers, 1987; Wilgus and counselors spend most of their time Shelley, 1988). All of this discourse has yet scheduling, testing, and shuffling papers. to result in a clear consensus on the school In an era of increased demand for accountcounselor's role or function.

A screen-space formulation for 2D and 3D direct manipulation

Rotate-Scale-Translate (RST) interactions have become the de facto standard when interacting with two-dimensional (2D) contexts in single-touch and multi-touch environments. Because the use of RST has thus far focused almost entirely on 2D, there are not yet standard techniques for extending these principles into three dimensions. In this paper we describe a screen-space method which fully captures the semantics of the traditional 2D RST multi-touch interaction, but also allows us to extend these same principles into three-dimensional (3D) interaction. Just like RST allows users to directly manipulate 2D contexts with two or more points, our method allows the user to directly manipulate 3D objects with three or more points. We show some novel interactions, which take perspective into account and are thus not available in orthographic environments. Furthermore, we identify key ambiguities and unexpected behaviors that arise when performing direct manipulation in 3D and offer solutions to mitigate the difficulties each presents. Finally, we show how to extend our method to meet application-specific control objectives, as well as show our method working in some example environments.
The growth and development of the superior oblique muscle and trochlear nerve in juvenile and adult goldfish

Superior oblique muscle/trochlear nerve pairs from goldfish of various ages (1‐5 years) have been examined light and electron microscopically. The muscle grows by enlargement (longitudinally and transversely) of individual fibers, and by addition of new ones at the rate of about 250/year. The nerve grows by enlargement of fibers, but few and perhaps nonew axons are added. The somata enlarge, and the neuromuscular synapses become much more numerous. The ratio of muscle fibers to nerve fibers increases from about 5 in the young to about 16 in the old fish.
