Permissible loads: biomechanical considerations.

Loads imposed on the spine by manual material handling should not be damaging to its structural elements. They should also, of course, be within the physical capabilities of the worker to handle. Current knowledge allows us to predict global loads on the spine from physical activities, but not the precise distribution of these loads. Therefore, general guidelines on permissible loads can be made, but not specific ones valid in all situations. To develop a model of permissible loads work factors such as object weight, location, load symmetry, load acceleration and body posture should be considered along with individual factors such as age, gender and physical capabilities, and time factors such as duration and frequency.
Flow of “Injury” Current and Patterns of Excitation during Early Ventricular Arrhythmias in Acute Regional Myocardial Ischemia in Isolated Porcine and Canine Hearts: Evidence for Two Different Arrhythmogenic Mechanisms

We recorded 60 DC-extracellular electrograms simultaneously from epicardial and intra- mural sites of the left ventricle of isolated perfused porcine and canine hearts during the first 15 minutes after occlusion of the left anterior descending coronary artery. During coronary occlusion, maximal current flow across the ischemic border occurred when normal cells had repolarized and ischemic cells had not. At that moment, maximal current sources at the normal side of the ischemic border were in the order of 2 μA/mm3 and maximal current sinks were -5 μA/mm3. During propagation of a broad wavefront in nonischemic myocardium, current sources in the wake of the wavefront were about twice as large. Ventricular premature beats usually followed deep negative T waves in ischemic myocardium, when “injury” currents were maximal. Earliest activity always occurred at the normal side of the ischemic border, and whenever Purkinje activity was recorded it preceded myocardial activity in both single premature beats and the initial beats of ventricular tachycardia (VT) or ventricular fibrillation (VF). For later beats of VT, circus movements with a diameter of 1-2 cm were responsible for continuation of the arrhythmia. Dimension and position of the reentrant circuit changed from beat to beat. In VF, fragmentation of wavefronts occurred, and multiple wavelets followed tortuous paths. Circus movements were seldom completed; when they were, their diameter was 0.5 cm. It is concluded that two mechanisms are responsible for the very early ischemic arrhythmias: one, a μfocalμ mechanism located at the normal side of the ischemic border, possibly induced by injury currents in normal Purkinje fibers and, two, macro- and micro-reentry in ischemic myocardium.

Interaction of interleukin-6 and the BMP pathway in pulmonary smooth muscle.

The majority of familial pulmonary arterial hypertension (PAH) cases are caused by mutations in the type 2 bone morphogenetic protein receptor (BMPR2). However, less than one-half of BMPR2 mutation carriers develop PAH, suggesting that the most important function of BMPR2 mutation is to cause susceptibility to a "second hit. " There is substantial evidence from the literature implicating dysregulated inflammation, in particular the cytokine IL-6, in the development of PAH. We thus hypothesized that the BMP pathway regulates IL-6 in pulmonary tissues and conversely that IL-6 regulates the BMP pathway. We tested this in vivo using transgenic mice expressing an inducible dominant negative BMPR2 in smooth muscle, using mice injected with an IL-6-expressing virus, and in vitro using small interfering RNA (siRNA) to BMPR2 in human pulmonary artery smooth muscle cells (PA SMC). Consistent with our hypothesis, we found upregulation of IL-6 in both the transgenic mice and in cultured PA SMC with siRNA to BMPR2; this could be abolished with p38(MAPK) inhibitors. We also found that IL-6 in vivo caused a twofold increase in expression of the BMP signaling target Id1 and caused increased BMP activity in a luciferase-reporter assay in PA SMC. Thus we have shown both in vitro and in vivo a complete negative feedback loop between IL-6 and BMP, suggesting that an important consequence of BMPR2 mutations may be poor regulation of cytokines and thus vulnerability to an inflammatory second hit.
Observability matrix and parameter identification: application to vehicle tire cornering stiffness

Tire cornering stiffness is an important parameter of vehicle modeling. Together with sideslip angle it is a transversal force governing tire-road contact, and like sideslip angle it can be used to evaluate lateral vehicle stability. This paper presents a vehicle sideslip angle observer based on a nonlinear vehicle model. This observer is validated with experimental data. Using the properties of the observability matrix, the paper shows that tire cornering stiffness is identifiable from the singular values of this matrix. An identification procedure is performed, by simulation, with double lane-change tests. Th results of this identification are validated on a slalom test. The study is carried out using a realistic vehicle simulator.
Stereo matching using normalized cross-correlation in LogRGB space

Stereo matching is the most important branch in computer vision. Due to various matching primitives, the stereo matching approaches are divided into three categories, namely, area-based matching method, feature-based matching method and phase-based matching method. In majority of existing matching algorithms, it is a critical assumption that the corresponding color values of stereo images are similar to each other. However, various radiometric factors affect image color in practice, such as lighting geometry, illuminant color, and imaging devices. Therefore, the conventional stereo matching methods based on such assumption may not obtain the expected results. In this paper, we present a new stereo matching measure that is unaffected by radiometric variations between stereo images. We use the color formation model based on Retinex [1] theory in logRGB space [2], and derive the disparity between two images using normalized cross-correlation. The occluded pixels are filtered out by cross-checking [3]. Experiments show that our method is robust to various radiometric factors between stereo images.
New direct-acting antiviral agents for the treatment of hepatitis C virus infection and perspectives

Until recently, the standard of care (SOC) for patients with chronic hepatitis C virus (HCV) infection has consisted of a combination of pegylated interferon-N1 plus ribavirin, administered for 24- to 48-weeks depending on the HCV genotype. The sustained virologic response rate for this SOC has been only about 50% in patients infected with genotype 1 HCV, the most prevalent genotype in Europe and North America. HCV therapy has been revolutionised recently by the approval of two direct-acting antiviral agents (DAA) against the NS3/4A serine protease for use in genotype 1 HCV, the ketoamide inhibitors boceprevir and telaprevir. The novel SOC marks the beginning of an extraordinary new era in HCV therapy. We review this new SOC with an emphasis on practical issues related to protease inhibitors, e.g. prescribing guidelines, futility rules and management of adverse events. We also give a perspective on what to expect in the coming years. Newer DAA with simplified dosing regimens and/or minimal toxicity which, when used in combination, will lead to viral eradication in most if not all CHC patients who undergo treatment. The novel agents in clinical development are paving the way for future interferon-sparing regimens.
Design of a trust model and finding key-nodes in rumor spreading based on Monte-Carlo method

This paper combines the results of research on social psychology, and has designed a trust model for rumor spreading. It is considered that when information exchanges between people, the trust of information is related to the interpersonal closeness. In addition, this paper uses Monte-Carlo method to find the key source nodes in rumor spreading by comparing the total number of spread nodes and spreading time. We find that the key nodes that impact the rumor spreading are not necessarily those with higher degree or betweeness. Our work will provide algorithm support for maintaining the credibility of network information and ensuring the security of network information content.
ONTOLOGY-BASED MODELS FOR PERSONALIZED E-LEARNING ENVIRONMENT

Students who use educational web-based applications aim at learning knowledge in chosen area. However, their level of knowledge and interests are different. For effective learning it is necessary to provide an individual approach to each student. Educational application should recommend students learning materials that are easily understandable according their level of knowledge and are interesting enough to keep the students’ attention. A solution is personalized approach to the student learning process by development of adaptive web-based applications. Personalization requires reasoning on knowledge related to each user and application domain. In this paper we describe a proposal of three main parts of adaptive web-based application – domain model, user model and adaptation model that we designed for the course of programming learning. We employ Semantic Web technologies in order to be able reuse existing educational materials and add a semantic layer responsible for personalization.
Color Image Compression using Hybrid Wavelet Transform with Haar as Base Transform

This paper proposes color image compression method using hybrid wavelet transform and compares it with results obtained using hybrid transform and multi-resolution analysis. Haar wavelet is widely used in image compression. So here Haar transform is selected as base transform and combined with non-sinusoidal transforms like Slant, Walsh and Kekre transform. Hybrid Haar wavelet transforms is generated using Kekre’s hybrid wavelet generation algorithm. Different sizes of component transforms are used to generate hybrid wavelet transform. Haar (32x32)-Slant (8x8) gives less error as compared to Haar-Walsh and Haar-Kekre Hybrid wavelet. Performance of hybrid wavelet is compared with hybrid transform and multi-resolution by varying the size of component transforms. Mean Absolute Error (MAE) and Average Fractional Change in Pixel Value (AFCPV) are used to compare visual quality of an image. Structural Similarity Index (SSIM) of Haar-Slant hybrid wavelet is computed on 16x16 blocked images and compared with its hybrid transform and multi-resolution analysis. Least RMSE value obtained at compression ratio 32 by HaarSlant hybrid wavelet with size 32-8 is 10.53. Mean absolute error is 7.32 in Haar-Slant hybrid wavelet with component size 16-16. Least AFCPV is 0.344 with component size 32-8 for the same.
Hazard Assessment of Debris Flows in the Reservoir Region of Wudongde Hydropower Station in China

The outbreak of debris flows in a reservoir region can affect the stability of hydropower stations and threaten the lives of the people living downstream of dams. Therefore, determining the hazard degree of debris flows in a reservoir region is of great importance. SPOT5 remote sensing images and digital elevation models are introduced to determine the characteristics of debris-flow catchments. The information is acquired through comprehensive manual investigation and satellite image interpretation. Ten factors that influence debris flow are extracted for the hazard assessment. The weight of these factors is determined using the analytic hierarchy process method. As a multi-criterion decision analysis method, fuzzy synthetic evaluation is applied for hazard assessment.
Extraction of tongue contours in X-ray images with minimal user interaction

In spite of the development of new imaging techniques, X ray images still keep a prominent place in studying articulatory phenomena. Indeed, they are still unsurpassed at obtaining an overall view of the moving vocal tract. However X ray images require that articulator contours are extracted by hand which is a tedious task. The paper describes an approach towards the automatization of tongue contour extraction. The "Snake" method introduced in computer vision to extract contours is unable alone to achieve the task. Therefore we make "Snakes" cooperate with an optical flow method, applied where contours are not sufficiently isolated from spurious contours. Our experiments have shown that the tongue is tracked successfully when it is visible, and that interaction with the user remains necessary when the tongue is obscured.
Effect of Cardiac Rehabilitation Program on Exercise Capacity in Women Undergoing Coronary Artery Bypass Graft in Hamadan-Iran

Objectives: The purpose of this study was to determine the effects of cardiac rehabilitation program (CRP) on exercise capacity and rate pressure product (RPP) in Iranian female patients undergoing coronary artery bypass grafting (CABG) in Hamadan, Iran. Methods: Sixty women after CABG were assigned into an exercise group (n = 30, mean age 58.5 ± 10.8 years), who performed physical training for 12 weeks, or a control group (n = 30, mean age 59.3 ± 8.6 years) who received usual care. Functional capacity and RPP were evaluated by six minute walking test (6MWT) and exercise test. Results: In comparison to before training, significant increases of estimated exercise capacity (10.72 ± 1.30 vs. 7.72 ± 1.6 MET’s, respectively) as well as 6MWT (556 ± 66.1 vs. 375.2 ± 28.1 meters, respectively) were observed in exercise group after 12 weeks training (P<0.001). Women increased their exercise duration time (464.6 ± 107.3 vs. 311.2 ± 101.7 seconds, respectively) by 49.2% and RPP (22361 ± 3206 vs. 20270 ± 2704.1, respectively) by 10.3% after training (P<0.001). However, no significant differences were found before and after CRP in the control group. Conclusions: Women referred for rehabilitation have similar levels of compliance and improvement in exercise capacity and supply of oxygen to cardiac muscles (measured by peak myocardial oxygen consumption). After CRP, women demonstrated significant improvements in exercise duration time, 6MWT, RPP and supply of oxygen to cardiac muscles. CRP can play an important role in improving functional independence in women.
Robustness of norm-driven cooperation in the commons

Sustainable use of common-pool resources such as fish, water or forests depends on the cooperation of resource users that restrain their individual extraction to socially optimal levels. Empirical evidence has shown that under certain social and biophysical conditions, self-organized cooperation in the commons can evolve. Global change, however, may drastically alter these conditions. We assess the robustness of cooperation to environmental variability in a stylized model of a community that harvests a shared resource. Community members follow a norm of socially optimal resource extraction, which is enforced through social sanctioning. Our results indicate that both resource abundance and a small increase in resource variability can lead to collapse of cooperation observed in the no-variability case, while either scarcity or large variability have the potential to stabilize it. The combined effects of changes in amount and variability can reinforce or counteract each other depending on their size and the initial level of cooperation in the community. If two socially separate groups are ecologically connected through resource leakage, cooperation in one can destabilize the other. These findings provide insights into possible effects of global change and spatial connectivity, indicating that there is no simple answer as to their effects on cooperation and sustainable resource use.
Chemotherapeutic Agents Taxol or Adriamycin-Inositol and myo Agents Green Tea or Dexamethasone / ChemopreventiveTumorigenesis : p 53-independent Efficacy of Mutation Accelerates Pulmonary p 53 A GermLine Updated

Recent evidence indicates that individuals with a p53 germ-line mutation (Li-Fraumeni syndrome) have a 50% risk of developing lung cancer by age 60. In this study, p53 heterozygous knockout mice and p53 transgenic mice carrying a dominant negative mutant were crossed with the A/J mouse, which is highly susceptible to lung tumor induction, to investigate whether a p53 germ-line mutation is a predisposing gene for carcinogen-induced pulmonary adenomas in mice. The number of lung tumors was not significantly increased in (TSG-p53 3 A/J)F1 p53 heterozygous knockout mice as compared with that in (TSG-p53 A/J)F1 wt mice 16 weeks after exposure toN-nitrosomethylurea (MNU). In contrast, an average of 22 lung tumors were observed in (UL53–3 A/ J)F1 mice carrying a mutant p53transgene (135Valp53) compared with an average of 7 lung tumors seen in (UL53–33 A/J)F1 wt mice after treatment with N-nitrosomethylurea. Similar enhancement of lung tumor multiplicity (;3-fold) was seen when mutantversuswt mice were treated with the tobacco-related carcinogens benzo[a]pyrene or 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanone. These results suggest that the mutant p53 transgene may have a dominant negative effect on the wt p53. The potential usefulness of this new mouse model in lung cancer chemoprevention and chemotherapy was examined. The chemopreventive efficacy of the green tea or a combination of dietary dexamethasone andmyoinositol and the chemotherapeutic efficacy of Taxol or Adriamycin was examined in wt mice or mice with a mutation in thep53gene. Mice treated with dexamethasone/myo-inositol and green tea displayed an average of 70 and 50% inhibition of lung tumors, respectively, regardless ofp53status. Similarly, when mice bearing established lung adenomas were treated with Taxol or Adriamycin, a decrease in tumor volume of ;70% was observed independent of p53mutation status. Thus, the (UL53–33 A/J)F1 p53 transgenic mouse seems to be an excellent model for human carriers of p53 germ-line mutations (Li-Fraumeni syndrome). Furthermore, the lung adenomas generated in this model possess mutations in both the K-ras proto-oncogene and thep53 tumor suppressor gene. This model should prove directly useful for chemoprevention and chemotherapy studies.
Predictive Learning in the Presence of Heterogeneity and Limited Training Data

A large number of real-world domains possess heterogeneity in their data, which implies that different partitions of the data show different relationships between explanatory and response variables. This increases the overall model complexity of predictive learning in the presence of heterogeneity. Additionally, a number of real-world domains lack sufficient training data, making the learning algorithm prone to over-fitting, especially when the model complexity is large. However, there often exists a structure among the data instances and their partitions which can be appropriately leveraged for reducing the model complexity along with addressing heterogeneity. In this paper, we present a framework for learning robust predictive models in real-world heterogeneous datasets which lack sufficient number of training samples. We demonstrate the usefulness of our framework in the domain of remote sensing for forest cover estimation. Through a series of comparative experiments with baseline approaches, we are able to show that our framework: (a) captures meaningful information about heterogeneity in the data, (b) improves prediction performance by addressing data heterogeneity, (c) is robust to over-fitting in the presence of limited training data, and (d) is robust to the choice of the number of partitions used for representing heterogeneity.
Late Shortening and Extensional Structures and Veins in the Western Margin of the Taconic Orogen (New York to Vermont)

Along the western margin of the Taconic orogen in New York and Vermont, undeformed quartz‐calcite veins commonly occur in the belt of melange that formed beneath the westward‐advancing Taconic Allochthon during the Middle‐Late Ordovician Taconic orogeny. The veins have mineral slickenfibers recording either reverse or normal slip. In New York, the reverse‐motion veins recording the latest phase of shortening are crosscut by the normal‐motion veins and faults. The shortening indicated by the reverse‐motion veins is correlated with the convergence along the Champlain thrust in Vermont, which is also crosscut by a significant, strike‐parallel normal fault. Fluid inclusion data from the veins, complemented by stable isotope data, lead to a reconstruction of the sequence of events in the context of a cooling of the fluids, which is consistent with crosscutting relationships among the veins. Following cessation of the convergence, there was regional extension of the western margin of the Taconic orogen, analogous to modern arc‐continent collisional orogens. Extension progressed to normal faulting without vein precipitation, and the normal faulting significantly modified the Allochthon‐melange contact. The timing of extension is constrained to follow the late Taconic thrusting and predate the latest Silurian, based on the similar fluid temperature/salinity of the reverse‐ and the normal‐motion veins, and contrast with veins nearby in Devonian rocks. Extensional, partial collapse of the orogen was accompanied or followed by rebound of the foreland basin, perhaps due to reduction of the thrust load and/or subducted slab breakoff. The systematic gradient of homogenization temperatures exhibited by the reverse‐motion veins along the orogen margin is interpreted to be caused by real differences in temperature of the vein‐forming fluids.
Mucosal inflammation in idiopathic bronchiectasis: cellular and molecular mechanisms

Bronchiectasis is a chronic and debilitating lung disease, characterised by irreversible dilatation of the bronchi as consequence of airway injury and remodelling due to recurrent or chronic airway inflammation and infection. The underlying aetiologies include autoimmune diseases, severe infections, genetic abnormalities and acquired disorders. The pathogenesis of bronchiectasis is poorly understood. Three distinct pathogenetic elements, namely infection, inflammation and enzymatic actions, which interact with each other, have been implicated in the pathophysiology of bronchiectasis. Some recent observations indicate that airway inflammation in bronchiectasis comes from a deregulated cytokine network independent of bacterial airway colonisation. In the present review, current knowledge about cellular and molecular inflammatory events in the dynamic process of host–pathogen interaction that are thought to play a relevant role in the pathogenic mechanisms of airway wall destruction leading to bronchiectasis are discussed.
