Eurographics/ Ieee-vgtc Symposium on Visualization 2008 Visual Analysis and Semantic Exploration of Urban Lidar Change Detection

Many previous approaches to detecting urban change from LIDAR point clouds interpolate the points into rasters, perform pixel-based image processing to detect changes, and produce 2D images as output. We present a method of LIDAR change detection that maintains accuracy by only using the raw, irregularly spaced LIDAR points, and extracts relevant changes as individual 3D models. We then utilize these models, alongside existing GIS data, within an interactive application that allows the chronological exploration of the changes to an urban environment. A three-tiered level-of-detail system maintains a scale-appropriate, legible visual representation across the entire range of view scales, from individual changes such as buildings and trees, to groups of changes such as new residential developments, deforestation, and construction sites, and finally to larger regions such as neighborhoods and districts of a city that are emerging or undergoing revitalization. Tools are provided to assist the visual analysis by urban planners and historians through semantic categorization and filtering of the changes presented.
Feature extraction of HRV signal using wavelet transform

This paper presents feature extraction and analysis of HRV signals using wavelet transform. Wavelets are utilized for noise removal and peak detection of ECG signals. Then the HRV signal is generated and analyzed for the MIT-BIH database. HRV is proving itself a very important tool for the effective analysis of ECG signals, as it is the measure of variability found in the heart rate. The results are based on some features of HRV signal which are extracted or calculated.
Angiogenesis in JAK2 V617F positive myeloproliferative neoplasms and ruxolitinib decrease VEGF, HIF-1 enesis in JAK2 V617F positive cells

Abstract Angiogenesis and JAK2 V617F mutation are common in BCR-ABL1 negative myeloproliferative neoplasms (MPNs). Ruxolitinib, a JAK inhibitor, is an effective treatment for some MPNs. However, the relationship between angiogenesis and JAK2 V617F and the effects of ruxolitinib on angiogenesis are still unknown. Here, we observed the correlation of JAK2 V617F mutation burden with VEGF, HIF-1a and microvascular density (MVD) in MPNs. We investigate the effect of ruxolitinib on the expression of VEGF and HIF-1α in JAK2 V617F positive cells. We found the expression levels of p-JAK2, VEGF, HIF-1a and MVD in the newly diagnosed MPNs were significantly increased and were related to the JAK2 V617F burden. Ruxolitinib can inhibit p-JAK2, VEGF, HIF-1a expression and suppress blood vessels’ formation in chick embryo choriallantoic membrane. Our findings indicated that angiogenesis is related to JAK2 V617F burden and ruxolitinib could decrease VEGF and HIF-1a expression in JAK2 V617F positive cells.
The role of advanced practice psychiatric nurses in treating tobacco use and dependence.

Tobacco use is treatable and the benefits of smoking cessation are impressive, yet like other health care providers, psychiatric nurses have failed to consistently assess and treat tobacco use effectively. Tobacco use continues to cause illness, disability, and death at unprecedented rates. Nicotine addiction is drug abuse and it is a chronic disease and needs to be treated as such. There are clear health benefits to smoking cessation regardless of the age of smoking initiation or the age of smoking cessation. Advanced practice psychiatric nurses (APPNs) are in a unique position to make an impact on a smoker's risk of suffering from tobacco-related diseases: the treatment of choice is the combination of pharmacotherapy and psychosocial interventions, both within the realm of APPN practice; psychiatric and substance abusing patients consistently demonstrate increased rates of cigarette smoking compared with healthy controls; and tobacco use is drug abuse, a treatable chronic disease. The ability of APPNs to deliver psychotherapeutic and pharmacologic care secures a position in the forefront of treating tobacco use. In addition to intervention, psychiatric nurses need to step up and take an active role in initiating and supporting tobacco control policy and legislation.
Immune-Mediated Myelopathy following Allogeneic Stem Cell Transplantation

We report a case of immune-mediated myelopathy occurring 4 months after unrelated bone marrow transplantation for myelodysplastic syndrome. After the tapering of cyclosporine for graft-versus-host disease prophylaxis, the patient developed several neurological symptoms mimicking the clinical features of multiple sclerosis (MS). Although neurological exacerbation was well stabilized with a bulk dose of corticosteroid, sustained improvement of neurological deficits occurred after the patient developed hematopoietic mixed chimerism (HMC). This experience may provide clinical evidence supporting the current therapeutic concept, in which HMC induction can potentially cure several immune diseases, including MS.
The BM-I2R Haitian-Créole-to-English translation system description for the WMT 2011 evaluation campaign

This work describes the Haitian-Creole to English statistical machine translation system built by Barcelona Media Innovation Center (BM) and Institute for Infocomm Research (I2R) for the 6th Workshop on Statistical Machine Translation (WMT 2011). Our system carefully processes the available data and uses it in a standard phrase-based system enhanced with a source context semantic feature that helps conducting a better lexical selection and a feature orthogonalization procedure that helps making MERT optimization more reliable and stable. Our system was ranked first (among a total of 9 participant systems) by the conducted human evaluation.
Hypertension and microalbuminuria in children with congenital solitary kidneys

Aim: According to the hyperfiltration hypothesis, a low nephron endowment will lead to hyperfiltration in the remaining glomeruli and is associated with systemic hypertension, proteinuria and glomerulosclerosis. Being born with one functioning kidney instead of two, for instance because of unilateral renal agenesis or multicystic dysplastic kidney, is a cause of congenital renal mass reduction.
Factors influencing postural management for children with cerebral palsy in the special school setting

Purpose. Postural management is used to help address the musculoskeletal and participation issues associated with cerebral palsy (CP). This study aimed to identify the factors influencing postural management in special schools. Method. A purpose-designed, cross-sectional, descriptive survey was sent to teachers, physiotherapists, occupational therapists and speech pathologists working with children with moderate-to-severe CP, aged 5–12 years, in special schools within South Australia. The instrument included four main areas: demographics, perceived benefits of postural management, factors facilitating or hindering the implementation of postural management programmes and suggestions for improvement. Results were analysed descriptively. Results. Forty-three therapists and 18 teachers completed the survey (response rate 81%). The most common factors hindering postural management were positioning equipment being unavailable or difficult to use, lack of time and school staff's knowledge and skills to carry out postural management. Facilitating factors included therapy staff providing a written postural management programme, open and regular communication between therapy and school staff and timetabling of postural management into the daily routine. Conclusions. Numerous factors impact on postural management for students in special schools. Practical solutions highlighted were increased training for school staff, timetabling of postural management into students' routines and provision of written postural management programmes.
Development of Anisotropic Structure by Solid-State Convection in the Earth ’ s Lower Mantle

Recent seismological observations show patches of highly anisotropic regions in the bottom of an otherwise isotropic lower mantle 1-4. These regions likely correspond to paleo-subduction or plume upwelling, but the exact cause for anisotropy is unknown. Both shape-preferred orientation (SPO) of elastically heterogenous materials 5 and lattice-preferred orientation (LPO) 6-8 have been proposed. Both of these mechanisms imply that large strain deformation occurs in anisotropic regions but the geodynamic implications are different. SPO as a mechanism would imply the presence of large elastic (and hence chemical) heterogeneity whereas LPO as a mechanism implies deformation at high stresses. Here we show, based on numerical modeling incorporating mineral physics of elasticity and LPO development, that the development of LPO associated with slab deformation in the deep lower mantle provides a likely mechanism for the presence of strong anisotropy in the circum-Pacific region. In this model, anisotropy in these regions is caused by high-stress, large-strain deformation due to the collision of subducted slabs with the core-mantle-boundary in the recent past.
Rotinas – Uma Revisão Teórica

This article intends to discuss the concept of routines and introduces the main advances in this field in the last years. The discussion about this concept – an important element in the neo-Schumpeterian theory – has been increased recently and various authors, included those connected to correlated areas like strategy, innovation and organizational change, have looked for a better understanding about it. In this way, a visit to the literature produced became an important point of departure. The first section of this article shows the recent debate about the concept of routines, and classifies the literature in three interpretations. Following there is a discussion about the origin of routines – their micro-foundations and their perspective in the level of firms. And at least I discuss the recent main contributions in theoretical and empirical area about roles and characteristics of routines.
Image Compression: An approach using Wavelet Transform and Modified FCM

In recent past, vector quantization has been observed as an efficient technique for image compression. In general, image compression reduces the number bits required to represent an image. The main significance of image compression is that the quality of the image is preserved. This in turn increases the storage space and thereby the volume of the data that can be stored. Image compression is the application of data compression technique on digital images. Wavelet Transform based image compression remain the most common among diverse techniques proposed earlier. Waveletbased image compression provides considerable improvements in picture quality at higher compression ratios. A moment ago Artificial Neural Network has attained popularity in the field of image compression. This paper proposes a technique for image compression using modified Fuzzy CMeans (FCM) algo rithm based vector quantization (VQ). The VQ codebook is generated by a modified FCM algorithm. The principal shortcoming of standard FCM algorithm is that the objective function does not think about the spatial dependence therefore it deal with image as the same as separate points. This proposed paper modifies the standard FCM algorithm that join together both the local spatial context and the nonlocal information into the stan dard FCM cluster algorithm using a novel dissimilarity index in place of the usual distance metric. Experiments are carried out in order to estimate the performance of the proposed modified FCM algorithm in image compression using standard image set. The results exposed the performance of our approach in perspective with other conventional image compression techniques Keywords- Bits, Codebook, Neural Networks (NN), Modified Fuzzy CMeans (FCM) Algorithm, Vector Quantization (VQ), Image Compression, and Wavelet Transform
A programmable dynamic interconnection network router with hidden refresh

A VLSI implementation of a programmable pipelined router scheme for parallel machine interconnection networks is presented in this paper. The implementation is based on a dynamic content-addressable memory (DCAM) that supports unique bit masking per entry. The number of required DCAM entries is extremely small; it is of the same order as the node degree (output ports). This, in turn, makes it possible to implement a dynamic content-addressable memory in order to reduce the physical size of the system. A DCAM is implemented with only six and a half transistors (one transistor is shared by two cells). We have provided circuitry and arranged timing to achieve refreshing of the stored data in a hidden fashion. In addition to the DCAM, we have incorporated a fast priority scheme that allows only one entry to he selected. The router executes routing algorithms in 1.5 clock cycles, this being the fastest approach for flexible routers. The prototype router has 24 entries, and is able to sustain a throughput of one routing decision per cycle.
Implications of the early X-ray afterglow light curves of Swift gamma-ray bursts

According to current models, gamma-ray bursts (GRBs) are produced when the energy carried by a relativistic outflow is dissipated and converted into radiation. The efficiency of this process, ∈ γ , is one of the critical factors in any GRB model. The X-ray afterglow light curves of Swift GRBs show an early stage of flattish decay. This has been interpreted as reflecting energy injection. When combined with previous estimates, which have concluded that the kinetic energy of the late (? 10 h) afterglow is comparable to the energy emitted in γ-rays, this interpretation implies very high values of ∈ γ , corresponding to? 90 per cent of the initial energy being converted into γ-rays. Such a high efficiency is hard to reconcile with most models, including in particular the popular internal-shocks model. We re-analyse the derivation of the kinetic energy from the afterglow X-ray flux and re-examine the resulting estimates of the efficiency. We confirm that, if the flattish decay arises from energy injection and the pre-Swift broad-band estimates of the kinetic energy are correct, then ∈ γ ? 0.9. We discuss various issues related to this result, including an alternative interpretation of the light curve in terms of a two-component outflow model, which we apply to the X-ray observations of GRB 050315. We point out, however, that another interpretation of the flattish decay - a variable X-ray afterglow efficiency (e.g. due to a time dependence of afterglow shock microphysical parameters) - is possible. We also show that direct estimates of the kinetic energy from the late X-ray afterglow flux are sensitive to the assumed values of the shock microphysical parameters and suggest that broad-band afterglow fits might have underestimated the kinetic energy (e.g. by overestimating the fraction of electrons that are accelerated to relativistic energies). Either one of these possibilities implies a lower γ-ray efficiency, and their joint effect could conceivably reduce the estimate of the typical e y to a value in the range ∼0.1-0.5.
Redundancy architectures for channel-based 3D DRAM yield improvement

The three-dimensional integrated circuit (3D IC) is considered a promising approach that can obtain high data band-width and low power consumption for future electronic systems that require high integration level. One of the popular drivers for 3D IC is the integration of a memory stack and a logic die. Because the yield of a 3D IC is the product of respective yields of the mounted dies, the yields of the memory dies and logic die must be high enough, or the 3D IC will be too expensive to be manufactured. To obtain a high yield of 3D ICs, efficient test and repair methodologies for memories are necessary. In this paper, we target the channel-based 3D dynamic random access memory (DRAM) and propose two 3D redundancy architectures, i.e., Cubical Redundancy Architectures 1 and 2 (CRA1 and CRA2). We use Wide-IO DRAM as an example for discussion. In CRA1, spares are associated with each DRAM die as in a conventional 2D architecture. In CRA2, we use a static random access memory (SRAM) on the logic die as spares. Experimental results show that the CRA1 can achieve up to 18% higher stack yield than traditional redundancy architecture with the same area overhead. On the other hand, the CRA2 can achieve the same yield as the CRA1 with 40% less spares, but 1.3% higher area overhead.
Red Light Stimulates Feeding Motivation in Fish but Does Not Improve Growth

Nile tilapia fish were individually reared under similar light levels for 8 weeks under five colored light spectra (maximum wavelength absorbance): white (full light spectrum), blue (∼452 nm), green (∼516 nm), yellow (∼520 nm) or red (∼628 nm). The effects of light on feeding, latency to begin feeding, growth and feed conversion were measured during the last 4 weeks of the study (i.e., after acclimation). We found that red light stimulates feeding, as in humans, most likely by affecting central control centers, but the extra feeding is not converted into growth.
Analysis of the Patients and Physicians Connection Network on an online Health Information Platform

Social network applications have gained popularity in the health domain as they bring health information seekers (patients and alike) and medication advice providers (physicians and other relevant actors) together. By employing a network science perspective, this research is aimed to understand an information network establishing connections among and between information seekers and providers. We found that such a connection network surfaces most of the essential characteristics of a typical complex network. Furthermore, a detailed structural analysis shows some intriguing relations and connection behaviours in the network. Implications of the findings are discussed from the perspectives of medical informatics and social network analysis.
Energy-efficient communication in wireless cable sensor networks

In this paper, we introduce a new type of sensor: cable sensor. Unlike traditional point sensors, this type of sensor has a rectangular sensing region with a processor installed on it to do processing and communication. The wireless network formed by this kind of sensor is called wireless cable sensor network (WCSN). We study energy-efficient communication algorithms in WCSNs. We address it in two ways: one is through reducing the total transmission power of processors while maintaining the connectivity of the network and the other is through scheduling cable sensors to let them take turns to go to sleep without affecting the coverage and connectivity of the network. In the first approach, we initially develop a distributed algorithm called DTRNG based on the relative neighbourhood graph. Later we enhance it to Algorithm determine the transmission power by removing the largest edge in CYCles (DTCYC). Mathematical proofs show that Algorithm DTCYC provides an optimal solution that can not only minimise the total processor transmission power but maintain the connectivity of the network as well. In the second approach, we propose a cable mode transition algorithm which determines the minimum number of active sensors to maintain K-coverage as well as K-connectivity required by the application. We discuss the relationship between coverage and connectivity and prove the theorems that lay the foundation for our algorithm. Simulation results demonstrate that our algorithm is efficient in saving energy.
De novo formation of cytokeratin filament networks originates from the cell cortex in A-431 cells.

Of the three major cytoskeletal filament systems, the intermediate filaments are the least understood. Since they differ fundamentally from the actin- and microtubule-based networks by their lack of polarity, it has remained a mystery how and where these principally endless filaments are formed. Using a recently established epithelial cell system in which fluorescently labeled intermediate filaments of the cytokeratin type can be monitored in living cells, we address these issues. By multidimensional time-lapse fluorescence microscopy, we examine de novo intermediate filament network formation from non-filamentous material at the end of mitosis and show that it mirrors disassembly. It is demonstrated that filament formation is initiated from the cell cortex without focal preference after cytokinesis. Furthermore, it is shown that this process is dependent on energy, on the integrity of the actin filament network and the microtubule system, and that it can be inhibited by the tyrosine phosphatase inhibitor pervanadate. Based on these observations, a two-step working model is proposed involving (1) interactions within the planar cortical layer acting as an organizing center forming a two-dimensional network and (2) subsequent radial dynamics facilitating the formation of a mature three-dimensional network.
An ambulance referral network improves access to emergency obstetric and neonatal care in a district of rural Burundi with high maternal mortality

In 2006, Médecins sans Frontières (MSF) established an emergency obstetric and neonatal care (EmONC) referral facility linked to an ambulance referral system for the transfer of women with obstetric complications from peripheral maternity units in Kabezi district, rural Burundi. This study aimed to (i) describe the communication and ambulance service together with the cost; (ii) examine the association between referral times and maternal and early neonatal deaths; and (iii) assess the impact of the referral service on coverage of complicated obstetric cases and caesarean sections.
CD4+ effector cells default to the Th2 pathway in interferon gamma- deficient mice infected with Leishmania major

Mice with homologous disruption of the interferon gamma (IFN-gamma) gene on the C57BL/6 background were infected with Leishmania major and the immune response assessed. In contrast to wild-type or heterozygous knockout mice, deficient animals were unable to restrict growth of the parasite and suffered lethal infection over 6-8 wk. Although wild-type and heterozygous littermates developed CD4+ cells that contained transcripts for IFN-gamma and lymphotoxin, typical of T helper type 1 (Th1) cells, the knockout mice developed CD4+ cells that contained transcripts for interleukin 4 (IL-4), IL-5, and IL-13, typical of Th2 cells. ELISPOT assays confirmed the reciprocal patterns of IFN-gamma or IL-4 production by T cells in similar frequencies in the respective groups of mice, and antibody analysis confirmed the presence of Th2- mediated isotype switching in the knockout mice. These data suggest that CD4+ T cells that normally respond to antigens by differentiation to Th1 cells default to the Th2 pathway in the absence of endogenous IFN-gamma.
