Multilayer Planar Tunable Filter With Very Wide Tuning Bandwidth

In this paper, we propose and develop a partially shielded tunable filter structure using a varactor-loaded split-ring resonator. The novel physical topology of the filter is suitable for vertical stacking of filters and enables a compact multilayer tunable filter for applications requiring a very wide tuning range. The capacitance range and ratio needed to achieve the designated tuning range are presented, and analytical solutions are given for the second and third higher order modes for synthesis in the spurious-free filter operation range. Two prototypes are developed. A partially shielded tunable filter using varactor-loaded split-ring resonators is developed to verify the design method and to demonstrate the wide tuning range of a tunable filter. To further extend the tuning range, a filter bank with three stacked tunable filters at different frequency bands are designed and developed. With slight overlap between neighboring bands, a continuous tuning range of more than 6:1 is achieved.
Transtornos de ansiedade e exercício físico

Resumo Objetivo: A maioria dos estudos sobre os efeitos ansioliticos do exercicio fisico, ate meados da decada de 90, foram realizados avaliando-se estados de ansiedade, com individuos jovens, universitarios ou atletas, que podem ser considerados pre-condicionados, limitando a validade das conclusoes para populacoes com ansiedade patologica. Na atualidade, o numero de estudos envolvendo pacientes com transtorno de ansiedade aumentou. O presente estudo tem por objetivo a revisao de artigos que discutem a influencia do exercicio fisico nos transtornos de ansiedade. Metodo: Foi realizada uma pesquisa no Medline, no periodo de 1966-1995 e 1996-2006, utilizando-se os descritores: anxiety, panic, phobic disorders, exercise, physical fitness, alem de referencias cruzadas dos artigos selecionados e analise adicional de referencias na literatura especifica do tema. Resultados: Os achados demonstraram desenhos heterogeneos assim como limitacoes metodologicas. As publicacoes mais recentes sao promissoras e acenam para a utilizacao de exercicios fisicos aerobios como auxiliares das terapeuticas tradicionais no tratamento dos transtornos de ansiedade. Conclusao: Verificou-se que os exercicios aerobios cuja intensidade nao ultrapasse o limiar de lactato podem ser os mais apropriados, mas ainda nao esclarecem as implicacoes dos exercicios anaerobios, sugerindo cautela na prescricao de exercicios para individuos com ansiedade patologica, principalmente em relacao aos exercicios anaerobios.
Challenges in Transitioning from Civil to Military Culture

A critical element for a successful transition is the ability to disclose, or make known, one's struggles. We explore the transition disclosure practices of Reserve Officers' Training Corps (ROTC) students who are transitioning from an individualistic culture to one that is highly collective. As ROTC students routinely evaluate their peers through a ranking system, the act of disclosure may impact a student's ability to secure limited opportunities within the military upon graduation. Through a qualitative interview study of active ROTC students (N=14) examining how they use information communication technologies (ICTs) to disclose their struggles in a hyper-competitive environment, we find they engage in a process of highly selective disclosure, choosing different groups with which to disclose based on the types of issues they face. We share implications for designing ICTs that better facilitate how ROTC students cope with personal challenges during their formative transition into the military.
Papillomavirus in esophageal papillomas and carcinomas

Human papillomavirus (HPV) has been implicated as a possible etiological factor in the development of squamous‐cell carcinoma of the esophagus. Published data demonstrating HPV DNA in these lesions have been conflicting, varying between failure to detect HPV DNA to detection of up to 60% to 70% of the biopsies harboring HPV DNA, mainly HPV 16 and HPV 18. We have analyzed esophageal carcinoma samples from 2 high‐risk areas, China and South Africa, using a degenerate PCR approach. All amplified products were cloned and sequenced. A broad spectrum of HPV types was demonstrated in 10/29 samples from China and 9/34 samples from South Africa. HPV types detected included mucosal types HPV 6, 18, 51, 52 and 57; cutaneous types HPV 9, 20, 24 and 25; and the putative new HPV types DL231, DL428 and DL436, with HPV 6/51, 6/57, 20/9 and 20/DL231 occurring as double infections. HPV 6 predominated (4 samples) in 11 esophageal papillomas originating from patients in Europe and tested for HPV DNA. Other HPV types present included HPV 20, DL284 and DL436. Another putative new HPV type, DL416, was identified in a dysplastic lesion of the esophagus. Int. J. Cancer 80:681–684, 1999. © 1999 Wiley‐Liss, Inc.
A cooperative program understanding environment

The large size and high-percentage of domain-specific code in most legacy systems makes it unlikely that automated understanding tools will be able to completely understand them. Yet automated tools can clearly recognize portions of the design. That suggests exploring environments in which programmer and system work together to understand legacy software. This paper describes such an environment that supports programmer and system cooperating to extract an object-oriented design from legacy software systems. It combines an automated program understanding component that recognizes standard implementations of domain independent plans with with a structured notebook that the programmer uses to link object-oriented design primitives to arbitrary source code fragments. This jointly extracted information is used to support conceptual queries about the program's code and design. <<ETX>>
Strategic management accounting and the strategising mindset in an English higher education institutional context

Purpose – The purpose of this paper is to explore the concept of strategic management accounting (SMA) in an English university. It is in search of and investigates SMA practices and processes, and their meaning to participants in an English university context. The higher education (HE) institution under research had gone through a major change a couple of years prior to this study, including implementation of new strategic management and management accounting practices.Design/methodology/approach – The approach taken is an interpretive one and the adopted methodology is grounded theory according to Glaser's evolved approach. Data collection took place largely through interviews and, where possible, participant observation.Findings – The main findings of the research concern the core concept of the strategising mindset, which encapsulates the institutional, divisional and individual stance towards strategy and SMA. The strategising mindset is understood as the belief system that is adopted with regard to .
Glial Cell Line–Derived Neurotrophic Factor Family Receptors Are Abnormally Expressed in Aganglionic Bowel of a Subpopulation of Patients with Hirschsprung's Disease

Hirschsprung's disease (HSCR), a congenital disease, is characterized by the absence of ganglion cells in the ganglion plexuses of the caudal most gut. In the aganglionic colon, the plexus remnants are replaced by aggregates of glial cells and hypertrophied nerve fibers. Signaling of glial cell line–derived neurotrophic factor (GDNF)-GFRAs-receptor tyrosine kinase (RET) is crucial for the development and maintenance of ganglion cells. Mutations of genes such as GDNF and RET lead to the perturbation of this signaling pathway, which causes HSCR. To understand the role of GFRAs in ganglion cells and the pathogenesis of HSCR, we intended to determine the specific cell lineages in the enteric nervous system that normally express GFRAs but are affected in HSCR. We studied colon biopsy specimens from 13 patients with HSCR (aged 1 day to 38 months) and 6 age-matched patients without HSCR as normal controls. RT-PCR, in situ hybridization, and immunohistochemistry were performed to examine the expression and cellular distributions of GFRAs in resected bowel segments of normal infants and those with HSCR. In normal infants and normoganglionic colon of patients with HSCR, the expression of GFRA1 was restricted to the glial cells and neurones of the ganglion plexuses. GFRAs expression was found to be markedly reduced in the aganglionic colons of 3 infants with HSCR but was unaffected in the aganglionic colons of 10 other infants with HSCR. Residual GFRA expression was restricted to enteric glial cells in the plexus remnants of the aganglionic colons. Hypertrophied nerve fibers were not found to express GFRA1. We provide the first evidence that abnormal expression of GFRAs in the enteric nervous system may be involved in the pathogenesis of HSCR in a subpopulation of patients.
The Performance of Block Codes Elwyn Berlekamp

I n his classic 1948 paper [10], Claude Shannon introduced the notions of communication channels and codes to communicate over them. During the following two decades, he remained active in refining and extending the theory. One of Shannon’s favorite research topics was the fundamental performance capabilities of long block codes. In the 1950s and 1960s this topic also attracted the active involvement of several of Shannon’s distinguished colleagues both at Bell Telephone Laboratories and at MIT, including P. Elias, R. M. Fano, R. G. Gallager, E. N. Gilbert, R. W. Hamming, I. M. Jacobs, B. Reiffen, D. Slepian, and J. M. Wozencraft, and several graduate students, including G. D. Forney and me. The work culminated in a book by Gallager [6] and in a sequence of two “Information and Control” papers by Shannon, Gallager, and Berlekamp [11]. In this article I present an overview of some of the more salient results and their impact.
Preschool Children With Developmental Delays and Limited English Proficiency

The number of children with Limited English Proficiency (LEP) in schools is increasing drastically. Included in this number are young children with LEP and developmental delays. This article provides information on second-language acquisition, details the type of programming used to educate children with LEP, and offers strategies to use when working with preschool children with LEP and developmental delays.
Cultural, Sociofamilial, and Psychological Resources That Inhibit Psychological Distress in African Americans Exposed to Stressful Life Events and Race-Related Stress

Empirical evidence suggests that African Americans (herein, all nonimmigrant persons of African heritage living in the United States) are at increased risk for exposure to stressful life events (e.g., Karlsen & Nazroo, 2002; McCord & Freeman, 1990; Thoits, 1991; Williams, Neighbors, & Jackson, 2003). Moreover, the health consequences associated with this increased risk are exacerbated by daily encounters with individual, institutional, and cultural racism (Clark, Anderson, Clark, & Williams, 1999; Harrell, 2000; Nazroo, 2003; C. E. Thompson & Neville, 1999; V. L. Thompson, 2002; Utsey & Ponterotto, 1996). Stressful life events and race-related stress have important consequences for the psychological and physical health of African Americans. As such, an important theoretical and practical question is: What protective factors can mitigate this stress and the subsequent risk for negative mental and physical health outcomes among African Americans? A significant related need is further understanding of the mechanisms whereby protective factors function to alleviate stress. In the present study, we examined the role of cultural, sociofamilial, and psychological resources in mitigating the deleterious effects of stressful life events and race-related stress in a sample of African American undergraduate college students. Our research examined the relative contributions of stressful life events versus race-related stress on psychological distress and compared two distress-deterring models (Ensel & Lin, 1991) to determine the specific mechanisms whereby psychological resources and cultural resources buffered participants from stress or enabled them to cope with psychological distress.
Evolution of the Angular Momentum of Protogalaxies from Tidal Torques

The growth of the angular momentum L of protogalaxies induced by tidal torques is reconsidered within the Zel'dovich approximation. We obtain a general expression for the ensemble expectation value of the square of L in terms of the first and second invariant of the inertia tensor of the Lagrangian volume enclosing the protoobject's collapsing mass. We then specialize the formalism to the particular case in which this volume is centered on a peak of the smoothed Gaussian density field and approximated by an isodensity ellipsoid. The result is the appropriate analytical estimate for the rms angular momentum of peaks to be compared against simulations that make use of the Hoffman-Ribak algorithm to set up a constrained density field that contains a peak with given shape. Extending the work of Heavens & Peacock, we calculate the joint probability distribution function for several spin parameters and peak mass M using the distribution of peak shapes, for different initial power spectra. The values of observed specific angular momentum versus mass are well fitted by our theoretical isoprobability contours. In contrast, the observed lower values for the specific angular momentum for ellipticals of the same mass cannot be accounted for within our linear regime investigation, highlighting the importance of strongly non-linear phenomena to explain the spin of such objects.
Structural characterization of oligosaccharides using MALDI-TOF/TOF tandem mass spectrometry.

Extensive cross-ring fragmentation ions, which are very informative of the linkages of the monosaccharide residues constituting these molecules, were readily observed in the MALDI-TOF/TOF/MS/MS spectra of oligosaccharides. These ions, in some cases, were more intense than the commonly observed Y and B ions. The A-type ions observed for the simple oligosaccharides allowed the distinction between alpha(1-4)- and alpha(1-6)-linked isobaric structures. The distinction was based not merely on the differences in the type of ions formed, but also on the ion intensities. For example, both alpha(1-4)- and alpha(1-6)-linked isobaric structures produce ions resulting from the loss of approximately 120 m/z units, but with different intensities, as a result of the fact that they correspond to two different ions (i.e., 0,4A- and 2,4A-ions), requiring different energies to be formed. Abundant A- and X-type ions were also observed for high-mannose N-glycans, allowing the determination of linkages. In addition, the high resolution furnished by MALDI-TOF/TOF allowed determination of certain ions that were commonly overlooked by MALDI-TOF or MALDI-magnetic sector instruments as a result of their lower resolution. Moreover, as a result of the fact that MS/MS spectra for parent ions and all fragment ions are acquired under the same experimental conditions, accurate determination of the molar ratios of isomeric glycans in a mixture analyzed simultaneously by MALDI-TOF/TOF tandem MS becomes possible.
MicroRNA-101 Inhibited Postinfarct Cardiac Fibrosis and Improved Left Ventricular Compliance via the FBJ Osteosarcoma Oncogene/Transforming Growth Factor-&bgr;1 Pathway

Background— Cardiac interstitial fibrosis is a major cause of the deteriorated performance of the heart in patients with chronic myocardial infarction. MicroRNAs (miRs) have recently been proven to be a novel class of regulators of cardiovascular diseases, including those associated with cardiac fibrosis. This study aimed to explore the role of miR-101 in cardiac fibrosis and the underlying mechanisms. Methods and Results— Four weeks after coronary artery ligation of rats, the expression of miR-101a and miR-101b (miR-101a/b) in the peri-infarct area was decreased. Treatment of cultured rat neonatal cardiac fibroblasts with angiotensin II also suppressed the expression of miR-101a/b. Forced expression of miR-101a/b suppressed the proliferation and collagen production in rat neonatal cardiac fibroblasts, as revealed by cell counting, MTT assay, and quantitative reverse transcription–polymerase chain reaction. The effect was abrogated by cotransfection with AMO-101a/b, the antisense inhibitors of miR-101a/b. c-Fos was found to be a target of miR-101a because overexpression of miR-101a decreased the protein and mRNA levels of c-Fos and its downstream protein transforming growth factor-&bgr;1. Silencing c-Fos by siRNA mimicked the antifibrotic action of miR-101a, whereas forced expression of c-Fos protein canceled the effect of miR-101a in cultured cardiac fibroblasts. Strikingly, echocardiography and hemodynamic measurements indicated remarkable improvement of the cardiac performance 4 weeks after adenovirus-mediated overexpression of miR-101a in rats with chronic myocardial infarction. Furthermore, the interstitial fibrosis was alleviated and the expression of c-Fos and transforming growth factor-&bgr;1 was inhibited. Conclusion— Overexpression of miR-101a can mitigate interstitial fibrosis and the deterioration of cardiac performance in postinfarct rats, indicating the therapeutic potential of miR-101a for cardiac disease associated with fibrosis.
Image Denoising Based On Wavelet for Satellite Imagery: A Review

In this paper studied the use of wavelet and their family to denoising images. Satellite images are extensively used in the field of RS and GIS for land possession, mapping use for planning and decision support. As of many Satellite image having common problem i.e. noise which hold unwanted information in an images. Different types of noise are addressing different techniques to denoising remotely sense images. Noise within the remote sensing images identifying and denoising them is big challenge before the researcher. Therefore we review wavelet for denoising of the remote sensing images. Thus implementing wavelet is essential to get much higher quality denoising image. However, they are usually too computationally demanding. In order to reduce the computational cost, we need to
Keyframe-based dense planar SLAM

In this work, we develop a novel keyframe-based dense planar SLAM (KDP-SLAM) system, based on CPU only, to reconstruct large indoor environments in real-time using a hand-held RGB-D sensor. Our keyframe-based approach applies a fast dense method to estimate odometry, fuses depth measurements from small baseline images, extracts planes from the fused depth map, and optimizes the poses of the keyframes and landmark planes in a global factor graph using incremental smoothing and mapping (iSAM). Using the fast odometry estimation, correct plane correspondences may be found projectively, and the pose of each frame can be estimated accurately even without sufficient planes to fully constrain the 6 degree-of-freedom transformation. The depth map generated from the local fusion process generates higher quality reconstructions and plane segmentations by eliminating noise. Moreover, explicitly modeling plane landmarks in the fully probabilistic global optimization significantly reduces the drift that plagues other dense SLAM algorithms. We test our system on standard RGB-D benchmarks as well as additional indoor environments, demonstrating its state-of-the-art performance as a real-time dense 3D SLAM algorithm, without the use of GPU.
Towards Platial Joins and Buffers in Place-Based GIS

Place-based GIS are still a novel research topic and break with some traditions of established systems. The typical spatial perspective is based on geometric reference systems that include coordinates, distances, topology, and directions; while the alternative platial perspective is usually characterized by place names and descriptions as well as semantic relationships between places. In past decades, space-based geographic information systems have made significant progress in terms of theories, models, functionalities, and applications. In contrast, place-based GIS are not yet well developed, although there is an increasing interest in platial and especially relational approaches. In this paper we take an example-driven, first step towards introducing place-based versions of the well known spatial join and buffer operations, and apply them to deal with place-based semantic compression and expansion in DBpedia.
Isolation and characterization of cDNAs encoding human brain ankyrins reveal a family of alternatively spliced genes

Ankyrins are a family of membrane-associated proteins that can be divided into two immunologically distinct groups: (a) erythrocyte- related isoforms (ankyrinR) that have polarized distributions in particular cell types; and (b) brain-related isoforms (ankyrinB) that display a broader distribution. In this paper, we report the isolation and sequences of cDNAs related to two ankyrinB isoforms, human brain ankyrin 1 and 2, and show that these isoforms are produced from alternatively spliced mRNAs of a single gene. Human brain ankyrin 1 and 2 share a common NH2-terminus that is similar to human erythrocyte ankyrins, with the most striking conservation occurring between areas composed of a repeated 33-amino acid motif and between areas corresponding to the central portion of the spectrin-binding domain. In contrast, COOH-terminal sequences of brain ankyrin 1 and 2 are distinct from one another and from human erythrocyte ankyrins, and thus are candidates to mediate protein interactions that distinguish these isoforms. The brain ankyrin 2 cDNA sequence includes a stop codon and encodes a polypeptide with a predicted molecular mass of 202 kD, which is similar to the Mr of the major form of ankyrin in adult bovine brain membranes. Moreover, an antibody raised against the conserved NH2- terminal domain of brain ankyrin cross-reacts with a single Mr = 220 kD polypeptide in adult human brain. These results strongly suggest that the amino acid sequence of brain ankyrin 2 determined in this report represents the complete coding sequence of the major form of ankyrin in adult human brain. In contrast, the brain ankyrin 1 cDNAs encode only part of a larger isoform. An immunoreactive polypeptide of Mr = 440 kD, which is evident in brain tissue of young rats, is a candidate to be encoded by brain ankyrin 1 mRNA. The COOH-terminal portion of brain ankyrin 1 includes 15 contiguous copies of a novel 12-amino acid repeat. Analysis of DNA from a panel of human/rodent cell hybrids linked this human brain ankyrin gene to chromosome 4. This result, coupled with previous reports assigning the human erythrocyte ankyrin gene to chromosome 8, demonstrates that human brain and erythrocyte ankyrins are encoded by distinct members of a multigene family.
