Miniaturization and enhancement performance of passive microwave components using HTS and thin film ferroelectric materials

Passive RF/microwave components (e.g. couplers, and filters) occupy big design area in the RF/microwave circuit and systems, especially when it work at low frequencies. This paper presents using of High Temperature Superconductor HTS for reducing the size of circuit design and maintains good performance, the surface impedance model is investigated and verified, branch-line coupler is designed on Lanthanum Aluminate (LaAlO3) substrate which is more suitable for HTS, the CST Electromagnetic wave simulator is used for design the coupler, all parameters of the designed coupler (Insertion Loss, Return Loss, and Isolation) show good enhancement when compared to previously published result of the coupler made of copper material. Also the size of the HTS coupler is small four times than the coupler made of copper material. A tunable frequency branch-line coupler is designed by using thin film layer of Strontium Titanate(SrTiO3) ferroelectric material, the thin layer is sandwiched between the LAO substrate and HTS microstrip line, the response shows a variation of frequency work with changing applied electric field.
Gaussian Model-Based Multichannel Speech Presence Probability

The knowledge of the target speech presence probability in a mixture of signals captured by a speech communication system is of paramount importance in several applications including reliable noise reduction algorithms. In this correspondence, we establish a new expression for speech presence probability when an array of microphones with an arbitrary geometry is used. Our study is based on the assumption of the Gaussian statistical model for all signals and involves the noise and noisy data statistics only. In comparison with the single-channel case, the new proposed multichannel approach can significantly increase the detection accuracy. In particular, when the additive noise is spatially coherent, perfect speech presence detection is theoretically possible, while when the noise is spatially white, a coherent summation of speech components is performed to allow for enhanced speech presence probability estimation.
Folding kinetics of proteinlike heteropolymers

Using a simple three‐dimensional lattice copolymer model and Monte Carlo dynamics, we study the collapse and folding of proteinlike heteropolymers. The polymers are 27 monomers long and consist of two monomer types. Although these chains are too long for exhaustive enumeration of all conformations, it is possible to enumerate all the maximally compact conformations, which are 3 ×3×3 cubes. This allows us to select sequences that have a unique global minimum. We then explore the kinetics of collapse and folding and examine what features determine the various rates. The folding time has a plateau over a broad range of temperatures and diverges at both high and low temperatures. The folding time depends on sequence and is related to the amount of energetic frustration in the native state. The collapse times of the chains are sequence independent and are a few orders of magnitude faster than the folding times, indicating a two‐phase folding process. Below a certain temperature the chains exhibit glasslike beh.
Feature selection based on random forest and application in correlation analysis of symptom and disease

A set of simple, rational diagnosis mode is the effective premise for intelligent diagnosis model. In this paper, selected the important symptoms of “five endogenous pathogens (FEP)” and measured these symptoms' contribution degree to FEP were main contents of this paper. Focused on the disease characteristics of “FEP”, we introduced the method of random forest (RF), and used it to build feature selection evaluation criteria, then proved the effectiveness of this method. On this basis, the article also explored the effective way to build an intelligent diagnosis model for “FEP”. Comparative experiment shown that RF model was superior in the diagnosis performance than the multi-classification support vector machine (SVM) classifier, and proven it to be an effective and high-performance “FEP” diagnosis model.
Regional Comparative Field Research

to use an implicit methodology of comparison with our culture in deciding what to describe and what to ignore. Such comparisons are not of the best sort, being largely unconscious, automatic, and, of course, ethnocentric. But we do something similar all the time, in a much more explicit way when we formulate theories for explaining cultural differences. Recognizing that differences even exist is a comparative process, and our continuing efforts to find general principles that account for differences (and similarities) depend entirely on drawing comparisons, arguing them with our colleagues-whether in informal discussions or in prmt-and then revising them in light of the compansons that our colleagues have used to challenge our for-
Somatic embryogenesis from immature zygotic embryos of annatto (Bixa orellana L.)

SummaryIn order to establish a protocol for somatic embryogenesis of annatto, Bixa orellana L. , seeds (70 d after anthesis) from field-grown orchards had their coats dissected off, and immature zygotic embryos were excised aseptically from immature seeds collected from field-grown trees and used as explants. Embryos were cultured onto MS medium supplemented with or without different combinations of plant growth regulators and activated charcoal. Direct somatic embryogenesis was induced on explants incubated either in Murashige and Skoog (MS), 2,4-dichlorophenoxyacetic acid (2,4-D), and/or kinetin-supplemented media after 25 d of culture. The highest frequencies of embryogenesis and embryos per explant were obtained on medium containing 2.26 μM 2.4-D, 4. 52μM kinetin, and 1.0 gl−1 activated charcoal. The presence of charcoal was critical in increasing embryos per explant, to reduce the time to obtain somatic embryos, and mainly to prevent callus proliferation and subsequent indirect somatic embryogenesis. No embryogenic response was achieved when mature embryos were used. It was also observed that embryogenic response was significantly affected by genotype. Histological investigations revealed that primary direct somatic embryos differentiated exclusively from the protodermis or together with the outer ground meristem cell layers of the zygotic embryo axis, and from the protodermis of zygotic cotyledons. Diverse morphological differences, including malformed embryos, were observed among somatic embryos. In spite of the high frequencies of histodifferentiation of all embryo stages, a very low conversion frequency to normal plants from somatic embryos was observed.
NAIST at 2013 CoNLL Grammatical Error Correction Shared Task

This paper describes the Nara Institute of Science and Technology (NAIST) error correction system in the CoNLL 2013 Shared Task. We constructed three systems: a system based on the Treelet Language Model for verb form and subjectverb agreement errors; a classifier trained on both learner and native corpora for noun number errors; a statistical machine translation (SMT)-based model for preposition and determiner errors. As for subject-verb agreement errors, we show that the Treelet Language Model-based approach can correct errors in which the target verb is distant from its subject. Our system ranked fourth on the official run.
Theory and Practice of School Communities

This article describes a study of a school community established within a larger high school as part of a district-wide effort to organize high schools into collections of smaller learning communities. The author presents an ecological framework of school communities that specifies their features across multiple dimensions and levels of schooling. The framework provides a scheme for bringing the entire organization into line with the concept of school communities and a guide for describing and assessing their functioning. Student- and teacher-survey measures were assembled and administered to gauge school community processes and goals specified in the framework. The findings indicated that students in the school community perceived their school environment and instruction in a manner more consistent with the framework than students in either the unrestructured school or magnet programs. School community teachers' relations with colleagues and students were also more consistent with the framework than other teachers 'relations.
Blood pressure and disability: novus orsa.

Disability has been defined as an inability to perform an action in a way that is consistent with the purpose of an organ or an organ system.1 Preclinical disability, often detected by self-report instruments, is the term for functional limitations that are not clinically diagnosed but nonetheless represent a transition between impairment and disability.1 Disability is a major public health problem,1,2 yet there is little information currently available with respect to the role of blood pressure (BP) in its development. It is clear that hypertension-associated diseases and events, eg, stroke, myocardial infarction, angina pectoris, heart failure, and peripheral vascular disease, are risk factors for disability.1,3,4 Considerably less attention has been focused on the more direct associations between hypertension and disability. In 1985, hypertension was related to disability in the Framingham Heart Study.3 Nine years later, Hubert and Fries5 reported an association between the diagnosis of hypertension and disability in a university runners club. Thirteen years later, in this issue of Hypertension , Hajjar et al2 report a statistically significant association between hypertension and disability and concurrent and prospective associations between systolic BP and disability among 999 stroke-free men and women participating in the Charleston Heart Study, 39% of whom were African American. Concurrently and prospectively measured systolic BP values were positively related to increasing disability as assessed by 3 functional measures: (1) Nagi’s Congruency in Medical and Self-Assessment of Disability Scale; (2) the Rosow-Breslaw Scale; and (3) the Katz Activities of Daily Living Scale. Thus, demonstration of a “dose-response” relationship between BP and multiple functional disability …
A finite mixture distribution model for data collected from twins.

Most analyses of data collected from a classical twin study of monozygotic (MZ) and dizygotic (DZ) twins assume that zygosity has been diagnosed without error. However, large scale surveys frequently resort to questionnaire-based methods of diagnosis which classify twins as MZ or DZ with less than perfect accuracy. This article describes a mixture distribution approach to the analysis of twin data when zygosity is not perfectly diagnosed. Estimates of diagnostic accuracy are used to weight the likelihood of the data according to the probability that any given pair is either MZ or DZ. The performance of this method is compared to fully accurate diagnosis, and to the analysis of samples that include some misclassified pairs. Conventional analysis of samples containing misclassified pairs yields biased estimates of variance components, such that additive genetic variance (A) is underestimated while common environment (C) and specific environment (E) components are overestimated. The bias is non-trivial; for 10% misclassification, true values of Additive genetic: Common environment: Specific Environment variance components of.6:. 2:. 2 are estimated as.48:. 29:. 23, respectively. The mixture distribution yields unbiased estimates, while showing relatively little loss of statistical precision for misclassification rates of 15% or less. The method is shown to perform quite well even when no information on zygosity is available, and may be applied when pair-specific estimates of zygosity probabilities are available.
Dust : A Visualization Tool Supporting Parents ’ School-Choice Evaluation

abstract How does a parent choose the best school for their child? Dust is an ongoing research project developed for Iridescent, an American NGO. The project's aim is to provide a freely available, web based information visual-ization tool that supports parents in exploring and comparing the educational offerings (from Pre-K to High School) from selected major cities in the United States, currently: New York, Los Angeles, and the San Francisco Bay Area. By leveraging a step-by-step decision making process, Dust helps to evaluate and compare school profiles based on multidimensional data-sets composed of general information (e. maps and close-up visualizations users can create custom profiles based on their needs and priorities and then perform a search for the most appropriate schools for their children. Dust aims to combine the capability of information visualization in depicting synthetic views of complex, multidimensional, and georeferenced data; with a rich, yet intuitive, web-user experience. The project aims to move away from a " by experts, for experts " design paradigm to a schools comparison information visualization " for the people "-providing real impact on their daily life, and future prospects, through improved choices.
Toward a Definition of the Lesbian Literary Imagination

In a review of Adrienne Rich's Diving into the Wreck, Margaret Atwood claims that "it is not enough to state the truth; it must be imaged, imagined. "' Contemporary women writers have waged a war of images in order to define an autonomous female imagination, and in the process they have questioned traditional literary images and offered radical reevaluations of the creative act. Women writers have chosen images and metaphors that have ranged from demon and sickness-images that evince the conflict and turmoil surrounding the woman's effort to create-to mother and androgyne-images designed to affirm and empower the creative woman. Some writers, such as Adrienne Rich and Monique Wittig, have recently proposed lesbian as the latest metaphor for female creativity.2 Although no little controversy surrounds a female creativity vested in lesbian sexuality, feminist theorists from different and sometimes opposing philosophical traditions have suggested and developed this metaphor as a positive, utopian image of woman's creativity.
Preclinical evidence of multiple mechanisms underlying trastuzumab resistance in gastric cancer

HER2-positive advanced gastric cancer patients frequently develop resistance to trastuzumab through mechanisms still poorly understood. In breast cancer, other members of the HER-family are known to be involved in trastuzumab-resistance, as is overexpression of the scaffold protein IQGAP1. In the present work, we investigated acquired resistance to trastuzumab in gastric cancer experimental models. Trastuzumab-resistant (HR) subclones derived from 3 HER2-overexpressing gastric cancer cells were generated and characterized for alterations in HER2-signaling mechanisms by next-generation sequencing, immunohistochemical, western blot and qRT-PCR techniques, and molecular modeling analysis. All subclones showed a reduced growth rate with respect to parental cell lines but each had a different resistance mechanism. In NCI N87 HR cells, characterized by a marked increase in HER2-signaling pathways with respect to the parental cell line, trastuzumab sensitivity was restored when IQGAP1 expression was silenced. AKG HR subclone showed higher HER3 protein expression than the parental line. High nuclear HER4 levels were observed in KKP HR cells. In conclusion, our study revealed that high IQGAP1 expression leads to resistance to trastuzumab in gastric cancer. Furthermore, 2 new mutations of the HER2 gene that may be involved in acquired resistance were identified in AKG HR and KKP HR subclones.
Exact path delay fault coverage with fundamental ZBDD operations

We formulate the path delay fault (PDF) coverage problem as a combinatorial problem that amounts to storing and manipulating sets using a special type of binary decision diagrams, called zero-suppressed binary decision diagrams (ZBDD). The ZBDD is a canonical data structure inherently having the property of representing combinational sets very compactly. A simple modification of the proposed basic scheme allows us to increase significantly the storage capability of the data structure with minimal loss in the fault coverage accuracy. Experimental results on the ISCAS85 benchmarks show considerable improvement over all existing techniques for exact PDF grading. The proposed methodology is simple, it consists of a polynomial number of increasingly efficient ZBDD-based operations, and can handle very large test sets that grade very large number of faults.
Fecal coliform elevated-temperature test: a physiological basis

The physiological basis of the Eijkman elevated-temperature test for differentiating fecal from nonfecal coliforms was investigated. Manometric studies indicated that the inhibitory effect upon growth and metabolism in a nonfecal coliform at 44.5 degrees C involved cellular components common to both aerobic and fermentative metabolism of lactose. Radioactive substrate incorporation experiments implicated cell membrane function as a principal focus for temperature sensitivity at 44.5 degrees C. A temperature increase from 35 to 44.5 degrees C drastically reduced the rates of [14C]glucose uptake in nonfecal coliforms, whereas those of fecal coliforms were essentially unchanged. In addition, relatively low levels of nonfecal coliform beta-galactosidase activity coupled with thermal inactivation of this enzyme at a comparatively low temperature may also inhibit growth and metabolism of nonfecal coliforms at the elevated temperature.
Race, Location, and Education

Throughout the 1990s, unprecedented numbers of Black mayors were elected in large American cities. Previous explanatory factors for Black mayoral success based on the 1970s and 1980s may no longer be adequate given the economic transformations to cities in the 1990s. This study examines structural demographic data to investigate the trends in Black mayoral success. The author finds that the proportion of the Black population, educational attainment, and regional location affect the electoral success of Black mayors.
The heave motion estimation for active heave compensation system in offshore crane

Active heave compensation is widely applied to decouple lifting loads from the ship motions due to wave excitation. This work presents a method of heave velocity estimation in active heave compensation system, which depends on the measured signals from an inertial measurement unit (IMU). The method is achieved by the motion transformation from IMU to the top of offshore crane and a heave filter which is a combination of a highpass filter and an integrator. Although the optimal cutoff frequency of the heave filter can be derived by analysing the error sources, it is difficult to use in the practical applications. The suboptimal or applied cutoff frequency of the heave filter in this work is determined by limiting the amplitude response error, and depends proportionally to the estimated dominant frequency of wave motion by the FFT. Because the heave filter introduces the phase error which impacts the estimation significantly, a lowpass filter is utilized in the modified heave filter for phase correction, and the lowpass cutoff frequency depends on the applied cutoff frequency and the dominant frequency of wave motion. Hence, all parameters for filtering process can be determined adaptively online. Active heave compensation system is simulated in the active heave compensation experimental facility and the compensation efficiency can reach 79.6%, verifying the feasibility of heave motion estimation.
High Order Correction Terms for The Peak-Peak Correlation Function in Nearly-Gaussian Models

Context. One possible way to investigate the nature of the primordial power spectrum fluctuations is by investigating the statist ical properties of the local maximum in the density fluctuation fields. Aims. In this work we present a study of the mean correlation function, �r, and the correlation function for high amplitude fluctuatio ns (peakpeak correlation) in a slighlty non-Gaussian context. Methods. From the definition of the correlation excess, we compute the Gaussian two-point correlation function and, using an expansion in Generalized Hermite polynomials, we estimate the correlation of high density peaks in a non-Gaussian field with generic distribution and power spectrum. We also apply the results obtained to a scale-mixed distribution model, which correspond to a nearly Gaussian model. Results. The results reveal that, even for a small deviation from Gaussianity, we can expect high density peaks to be much more correlated than in a Gaussian field with the same power spectrum. In addition, the calculations reveal how the amplitude of the peaks in the fluctuations field is related to the existing correlations. Conclusions. Our results may be used as an additional tool to investigate the behavior of the N-point correlation function, to underst and how non-Gaussian correlations affect the peak-peak statistics and extract more information about the statistics of the density field.
Music and Meaning on the Factory Floor

This article examines an unexplored topic within industrial sociology—the terrain of music for meaning making on the factory floor. The article is based on ethnographic research undertaken in a blinds factory. Although contemporary popular music appears to speak only rarely to the arena of work, this article shows that workers reappropriated music to articulate their experience of working in the factory. Many workers independently created meaning systems through music, which displayed both a negative experience of the work and an active resistance and defiance. The way in which this functioned was through the process of avowal in which choruses of songs allowed deeply felt, but usually tacit, feelings to be given direct articulation. Social listening in the factory played a key role in shaping the way in which music was used to create meaning.
Author's personal copy H1 filtering for discrete-time linear systems with bounded time- varying parameters

In this paper, the problem of linear parameter varying (LPV) filter design for timevarying discrete-time polytopic systems with bounded rates of variation is investigated. The design conditions are obtained by means of a parameter-dependent Lyapunov function and extra variables for the filter design, expressed as bilinear matrix inequalities. An LPV filter, which minimizes an upper bound to the H1 performance of the estimation error, is obtained as the solution of an optimization problem. A convex model to represent the parameters and their variations as a polytope is proposed in order to provide less conservative design conditions. Robust filters for time-varying polytopic systems can be obtained as a particular case of the proposed method. Numerical examples illustrate the results. & 2009 Elsevier B.V. All rights reserved.
