Transmission diversity in wideband CDMA

We study two transmission diversity techniques in wideband CDMA system. The studied techniques are time switched transmission diversity (TSTD) and selection transmission diversity (STD). In TSTD encoded bits are distributed between all transmission antennas. In STD encoded bits are transmitted through the best transmission antenna. STD requires that a mobile measures which is the best antenna and transmits this information to the base station. We have compared these two methods and a single antenna case and found that TSTD is over 2 dB better and STD 3 dB better than the single antenna case. We have also found that in WCDMA STD can tolerate relatively high amount of feedback signaling errors.
Adult Stem Cell Based Enhancement of Nerve Conduit for Peripheral Nerve Repair

Abstract : Musculoskeletal trauma is frequently accompanied by injuries to peripheral nerves; if not repaired, the trauma can lead to significant dysfunction and disability. While nerves have the ability to regenerate and to reconnect across a limited gap, surgical intervention is often required to assist them in bridging a larger gap. Typically, surgeons will transplant a less important nerve from elsewhere in the body to the site of injury to provide a patch for the injured nerve. However, acceptable donor nerves are often not available for this purpose, particularly in patients suffering multiple extremity injuries or faced with traumatic amputations. Alternatives include the use of a blood vessel graft or a synthetic nerve guide, although these devices are only effective over distances less than 3 cm, mainly because of their lack of appropriate nerve-enhancing biological activities. In our current work, we have identified and isolated stem cells from the injured tissue site that have wound healing promoting activities.
Structural proteomics: Do computers help?

Characterizing the structure of proteins is a fundamental issue for understanding the biological systems in all living creatures. Presently, the study of the structural properties of proteins is based on mathematical computational software that automatically read protein databases [1] noted as amino acids or nucleotides. Multiple codes simultaneously evaluate the primary or tertiary structure of proteins with different mathematical algorithms that vary in degree of complexity [2]. These algorithms experimentally verify any regularity, and 'virtually' build proteins from certain physico-chemical properties.
Living artefact, personal ecosystem, biocultural schizophrenia: a novel synthesis of processual and post-processual thinking

For well over a decade archaeological theory has been discussed in terms of a number of problematic yet familiar dichotomies. Prominent examples would include the distinction between processualist (scientific) and postprocessualist (post-modernist) thinking, and its concomitant distinctions of biology versus culture, Positivism versus Relativism, and Realism versus Idealism. This paper outlines a novel framework (Cultural Virus Theory) which crosscuts these familiar dichotomies, while also suggesting new explanatory possibilities. Recent convergent trends in archaeological theory are summarised. Some of the basic principles of the theory are defined. It is argued that ideas, rituals, and artefact production systems are culturally reproduced life-forms (‘viral phenomena’ or ‘living artefacts’); that people are therefore biocultural ecosystems of more than one lifeform (‘personal ecosystems’); and that the internal constituent life-forms of personal ecosystems may be found in both symbiotic, and parasitic or predatory relationships, just as are those of larger ecosystems. Human actions, therefore, cannot be approached as if they constitute the behaviour of a single united organism; as ecosystems, people are often subject to internal adaptive conflict and are, in short, ‘biocultural schizophrenics’. Lastly, the anatomy of the synthesis is briefly discussed with reference to first post-processual, and then processual approaches to the familiar ‘megalith icon’ of monuments and their associated rituals — termed ‘megalithic religions’ for convenience — in Neolithic north-west Europe.
miR-155 and miR-34a regulate proinflammatory cytokine production by human monocytes

Dysregulated proinflammatory activation of synovial monocytes and macrophages is of fundamental importance in the pathogenesis of rheumatoid arthritis (RA). Recently, microRNAs (miRNA) have been identified as critical post-transcriptional regulators of many components of immune responses. The aim of our study was to investigate the role of candidate miRNAs miR-155 and miR-34a in the activation of RA synovial fluid (SF) and blood monocyte/macrophages. CD14 cells from SF or blood of RA patients and CD14 cells from blood of …
Improving Efficiency in Budgeting – An Interventionist Approach to Spreadsheet Accuracy Testing

Over the past three decades, the reliance on sophisticated spreadsheets for budgeting has emerged as a standard in most organizations (Hesse and Hesse Scerno, 2009). Despite these technological advancements, rich empirical evidence documents that technologically induced ‘spreadsheet errors’ can substantially lower the accuracy of spreadsheets (Powell et al., 2009). These errors lead to suboptimal decision making and biased performance assessment. The aim of this paper is to examine how spreadsheet error can be detected and prevented in the budgeting process. Our research design applies models of spreadsheet accuracy testing (SAT) from Kruck (2006) and Vessey (1985). We thereby illustrate the error reduction process in budgeting as well as future spreadsheet error prevention through the use of VBA. We base our analyses on a unique dataset (interviews, participating observations, technical artifacts) gathered through ‘action research’ at Chinese-Danish government organization, which uses budgets for assessing applications on research funding. Our results confirm and extend existing theory in the field of budgeting and SAT and provide interesting findings: First, we show that later spreadsheet error in budgeting is already rooted in a poor conceptualization of the budget template, in non-workflow-oriented imputation of data and poor documentation of data requirements. Second, we illustrate how the accuracy of spreadsheets substantially improves by introducing even simplistic VBA. Third, we present evidence that the flexibility of the budgeting template itself to changes in the organizational environment foster spreadsheet accuracy in the long term.
A LIBRARY OF LARGE-SCALE DISTRIBUTED SPATIAL DATA STRUCTURES

DGrid is a generic C++ library that addresses querying of spatially clustered point data. The library is based on the Templated Composite design pattern, which is a novel adaptation of the Composite pattern. DGrid uses template metaprogramming techniques to improve performance and flexibility, and to allow static type checking. The library provides support for queries on distributed data. Use cases are provided as evidence for the library’s practical merit.
Cuerpo privado, imagen pública: el autorretrato en la práctica de la fotografía digital

This paper show some thoughts about the self-portrait as an extended practice on the Internet, not only as a representation of users of Social Network Sites (profile pictures for example) but also as a creative and playful self-reflective practice on the self, the body and the personal identity. To some authors, the practice of self-portraits is related to control forms and empowerment, in particular, the self-portraits made by women. For other authors, it seems to be the popularisation of a practice previously reserved to artists, while others point to the therapeutic and personal transformation powers of the selfportrait. What seems to be undoubted is the relationship between the self-portrait and the everyday narratives of the self and, on the Internet, this personal and intimate practice becomes public and even creates an audience. In this sense, the self-portrait could be understood as a new cultural form of self-presentation that could be understood as both, the public performance of the personal identity and the result of a performative practice with the own body.
Edema and Necrosis in Experimental Cerebral Infarction

Some cerebral edema always accompanies ischemic infarction and contributes to symptoms in a substantial number of human cases. 1 Although the edema usually is greater with large than with small infarcts, 2 morphologic correlation sometimes is poor. This raises the question in ischemic lesions whether there is a stage of prenecrotic swelling or of swelling independent of necrosis; the corollary question is whether swelling itself contributes to the eventual size of the brain infarct. To investigate this we attempted to induce in rats graded anoxicischemic cerebral lesions; small animals were chosen in order to have sufficient numbers to analyze results. Because of the well-known narrow margin in rats between producing no brain lesion at all and producing death by anoxia, a modification of Levine's 3 technique combining carotid ligation with anoxic exposure was employed. Whereas Levine (and Spector 4 ) exposed animals to severe hypoxia for variable periods of time
Learning-based automatic breast tumor detection and segmentation in ultrasound images

Ultrasound (US) images have been widely used in the diagnosis of breast cancer in particular. While experienced doctors may locate the tumor regions in a US image manually, it is highly desirable to develop algorithms that automatically detect the tumor regions in order to assist medical diagnosis. In this paper, we propose a novel algorithm for automatic detection of breast tumors in US images. We formulate the tumor detection as a two step learning problem: tumor localization by bounding box and exact boundary delineation. Specifically, the proposed method uses an AdaBoost classifier on Harr-like features to detect a preliminary set of tumor regions. The preliminarily detected tumor regions are further screened with a support vector machine using quantized intensity features. Finally, the random walk segmentation algorithm is performed on the US image to retrieve the boundary of each detected tumor region. The proposed method has been evaluated on a data set containing 112 breast US images, including histologically confirmed 80 diseased ones and 32 normal ones. The data set contains one image from each patient and the patients are from 31 to 75 years old. Experiments demonstrate that the proposed algorithm can automatically detect breast tumors, with their locations and boundary shapes retrieved with high accuracy.
Image Enhancement using Sharpen Filters

Image processing is basically the use of computer algorithms to perform image processing on digital images. Digital image processing is a part of digital signal processing. Digital image processing has many significant advantages over analog image processing. Image processing allows a much wider range of algorithms to be applied to the input data and can avoid problems such as the build-up of noise and signal distortion during processing of images. In this paper, a new nonlinear filtering technique is introduced for enhancement of images that are highly contaminated by impulse noise. The proposed filtering technique is more effective in eliminating impulse noise and preserving the image features. The filter replaces a corrupted pixel by the median value or by its processed neighboring pixel value.
Illusory Motion within Still Pictures: The L-Effect

In 1980. while experimenting with pictorial configurations I found that. when a uniformly coloured band of an appropriate width, which I call a coloured avenue, crosses a black and white grating roughly a t a right angle, one perceives within the avenue an intense illusory motion. As a result, still pictures becomelive: that is what led to the phenomenon becoming known as the LEffect. In addition, as the effect appears whenever one watches the pictures, the motion seemingly never stops: thus the name ‘Perpetuum Mobile’ pictures. I later learned that. in 1957, D. M. MacKay had reported that a ‘trickling motion’ could be observed when a black and white grating was simply interrupted on a certain width by a white space [ I ] . Further experimentation proved, however, that colour is indeed an essential factor of the L-Effect and that the intensity of the effect varies with the choice of colour. The L-Effect has the following characteristics: ( a ) The width of the avenue is critical and for each grating there is an optimum width producing the strongest effect. (b) When two or more avenues are superimposed on a grating with a certain separation between them. the illusion is accentuated. (c) Fo r each picture there is an optimum illumination-neither too bright nor too dim-producing the most intense motion. (d ) There is also an optimum distance between picture and viewer, which varies with thesca leof thegra t ingand the wid thof theavenues . (e )The L-Effect is much stronger with binocular than with monocular vision. ( f ) By introducing enough dark ‘figures’ (lines. spots etc. . . . ) within the uniformly coloured ‘ground’ formed by the avenues. the motion can be stopped. (8) A simple colour photograph of a Perpetuum Mobile picture also shows the motion in the coloured avenues. though i t has to be observed at a closer distance. This allows to say. paradoxically. that whereas it takes a movie camera to photograph normal motion. the motion of the L-Effect can-seemingly-be photographed with a still camera.

Brief, Intensive Behavioral Treatment of Food Refusal Secondary to Emetophobia

Emetophobia, a fear of vomiting, has been reported in both adults and children but is not well documented. This study describes the treatment of an 8-year-old girl who developed emetophobia and food refusal after an acute illness. The intervention consisted of an exposure-based treatment conducted over 7 days at a feeding program. The girl was discharged consuming all of her nutrition by mouth, and her gastrostomy tube feedings were eliminated.
DMT systems, DWMT systems and digital filter banks

A multicarrier modulation system called discrete multitone (DMT) was chosen by the American National Standards Institute (ANSI) as a working standard for asymmetric digital subscriber line (ADSL) signaling. The DMT system uses the inverse and forward discrete Fourier transform (DFT) for modulation and demodulation. An alternative to the classic DMT system is to substitute a discrete wavelet transform in place of the DFT as the modulating transform. This new method is called discrete wavelet multitone (DWMT) signaling, and has been shown to be superior to the DMT system in certain channel environments. This paper illustrates that the DMT system and the DWMT system are both based on the theory of M-band wavelet filter banks. In particular, DMT and DWMT are linked formally through a discussion of digital multirate filter hanks and digital transmultiplexer. In addition the advantages of wavelet transform-based transmultiplexers over DFT-based transmultiplexers are discussed. <<ETX>>
Mean shift‐based clustering analysis of multispectral remote sensing imagery

In clustering analysis of remote sensing imagery, a commonly held assumption is that the feature space can be modelled as a mixture of Gaussians. However, the assumption is not true for many real data and therefore incorrect classification results are often obtained by parametric methods. Nonparametric methods in feature space analysis can avoid the use of the normality assumption. Arbitrarily structured feature spaces can be analysed only by means of nonparametric methods as these methods do not have embedded assumptions. The mean shift is a basic computational module of the nonparametric technique in pattern recognition. The mean shift procedure can be used to cluster multispectral remote sensing imagery. Earlier clustering techniques based on the mean shift used a single scale over the entire feature space and were not feasible for the analysis of complex multimodal feature spaces. In this paper, we present an adaptive mean shift method in which local scale information is involved. The proposed algorithm can find arbitrary density, size and shape clusters in remote sensing imagery. The method is a simple technique of unsupervised image classification. We demonstrate its advantages in classification accuracy over earlier methods described in this paper.
Learning in 3D: Students' Experiences of Online Projects in NSW Schools.

Student participation in online learning activities is a growing priority for Australian government schools. ‘Online projects’ have emerged as a new learning form, building on non-computer problem-based learning approaches. This paper reports on a study of online learning projects implemented in classes from year 2 to year 11. The purported benefits of online learning were explored through in-depth case studies of the selected projects. Results of the study are presented, providing a window onto the learning events as each project unfolded and highlighting the achievements of students. The study’s findings have significant implications for education systems and teachers, in the design and implementation of online projects as part of an effective learning provision for students. The potential and limitations of an online project approach are placed in the context of online learning developments occurring in New South Wales and Australia.
Prevalence of Hypertension Among Fisherman Community in The Island of Bengre, Mangalore

Hypertension is one of the major causes of disease and disability worldwide. It is associated with an increased risk of stroke and myocardial infarction etc.It is easy to detect by simple means, but most of them are unaware of their hypertension and had no treatment. In those on treatment, blood pressure control is unsatisfactory. The factors affecting the prevalence of hypertension are many that including ethnicity, life style changes and diet. Epidemiological data shows variation in prevalence of hypertension. Some show an increase in blood pressure with age, while others show no significant increase. Present study examined 1016 (M: 500; F: 516) from local fisherman community in the age group of 2070 years. Study showed 4.62% prevalence of hypertension (M: 4.40; F: 4.84) and 40% were aware of their hypertensive state. Only 4.2% were on regular treatment and the rest, noncompliant population had uncontrolled blood pressure. None had any idea about hypertensive related risk factors, symptoms, complications and preventive measures. Hypertension among fisherman community showed lower prevalence than compared to various prevalence studies in

Methods to Synchronize Estrous Cycles of Postpartum Beef Cows with Melengestrol Acetate

Abstract This review considers recently developed methods to control estrous cycles of postpartum beef cows with melengestrol acetate ( MGA ®, Pharmacia Animal Health, Kalamazoo, MI). Melengestrol acetate is an orally active progestin that will suppress estrus and prevent ovulation in cattle if consumed on a daily basis. The duration of feeding may vary among the various protocols that are available, but the level of feeding (0.5 mg/d per animal) is consistent and critical to success. Feeding MGA® for 14 d followed by injection of prostaglandin F 2α ( PGF 2α ) 17 to 19 d after MGA® withdrawal was developed as an effective method of estrous cycle control for heifers. Studies in postpartum beef cows identified significant improvements in specific reproductive endpoints among cows that received MGA® prior to the administration of PGF 2α compared with cows that received PGF 2α only, including increased estrous response and improved synchronized conception (CR) and pregnancy (PR) rates. Recently, an improvement in synchrony of estrus was reported, without compromising fertility, in postpartum beef cows that were pretreated, either short- or long-term, with MGA® prior to gonadotropin-releasing hormone (GnRH) and PGF 2α . We proposed the general hypothesis that progestin (MGA®) treatment prior to the GnRH-PGF 2α estrus synchronization protocol would successfully 1) induce ovulation in anestrous postpartum beef cows; 2) reduce the incidence of a short luteal phase among anestrous cows induced to ovulate; 3) increase estrous response, synchronized CR, and PR; and 4) increase the likelihood of successful fixedtime insemination. Protocols that utilize this sequential approach to control the estrous cycle include the MGA® Select and 7-11 Synch protocols. The flexibility in matching specific protocols with the particular management system involved is a major advantage in using MGA® to control estrous cycles in cows.
