Imaging Intracranial Vessel Wall Pathology With Magnetic Resonance Imaging: Current Prospects and Future Directions

To date, the probable cause of ischemic stroke is often inferred from the size and location of the infarct, in combination with an evaluation of the heart and the presence of extracranial arterial occlusion or high-grade stenosis.1 Currently used conventional lumenography-based methods such as digital subtraction angiography, computed tomography angiography, and magnetic resonance (MR) angiography are used to determine the presence of such an acute occlusion or high-grade arterial stenosis. From extracranial studies, it is known that luminal narrowing may be absent in patients with severe atherosclerosis owing to arterial remodeling.2–4 Therefore, these methods do not provide information about the underlying pathological processes, which most often involve the vessel wall.5 Vessel wall changes such as vessel wall thickening, enhancement, or the presence of vulnerable atherosclerotic plaques without luminal stenosis are therefore often missed but might be of importance for a better understanding of ischemic stroke.6 Furthermore, intracranial atherosclerosis is an important cause of ischemic stroke7 and often involves the vessel wall. Patients with intracranial atherosclerosis have high recurrent stroke rates,8 and increasingly more attention is being directed to the assessment of the intracranial vessel wall, necessitating an imaging technique directly assessing the intracranial vessel wall. MR imaging (MRI) seems the most promising technique to reliably image intracranial vessel wall pathologies because of its superior soft tissue contrast. Recent advances in MRI9 have made it possible to obtain information about these abnormalities within the intracranial vessel wall, which provides an imaging tool to investigate the role of intracranial vessel wall abnormalities in the diagnosis of stroke. In this review, we discuss the current status of intracranial vessel wall MRI and its potential to identify different intracranial vessel wall pathologies. First, we present the state-of-the-art MRI methods to visualize the intracranial vessel wall …
Semi-supervised fall detection algorithm using fall indicators in smartphone

Fall injury is a health-threatening incident that may cause instant death. There are many research interests aimed to detect fall incidents as early as possible. Fall detection is envisioned critical on ICT-assisted healthcare future. In this paper, we study fall indicators from smartphone perspective. We use smartphone built in accelerometer and orientation sensor to recognize various falls. We are subsequently to propose a semi-supervised algorithm design for mobile phone as a part of our ongoing project on fall detection application and system with smartphone. The genuine fall event will be evaluated based on multiple indicators as the reference to fall detection. We firstly obtain 1st supervised algorithm with indicators as our features trained using decision tree. After several phases of observation, 1st algorithm becomes our reasoning basis that helps us to propose another accurate, robust, and ideal semi-supervised algorithm for smartphone. The result of our experiment is presented as profiles of various fall characters being used as observation basis in 2nd algorithm. Our experiment shows that our study is promising to be the base of newer algorithm. It is feasible and accurate to detect a genuine fall event with smartphone.
Evaluating Utility of Data Sources in a Large Parallel Czech-English Corpus CzEng 0.9

CzEng 0.9 is the third release of a large parallel corpus of Czech and English. For the current release, CzEng was extended by significant amount of texts from various types of sources, including parallel web pages, electronically available books and subtitles. This paper describes and evaluates filtering techniques employed in the process in order to avoid misaligned or otherwise damaged parallel sentences in the collection. We estimate the precision and recall of two sets of filters. The first set was used to process the data before their inclusion into CzEng. The filters from the second set were newly created to improve the filtering process for future releases of CzEng. Given the overall amount and variance of sources of the data, our experiments illustrate the utility of parallel data sources with respect to extractable parallel segments. As a similar behaviour can be expected for other language pairs, our results can be interpreted as guidelines indicating which sources should other researchers exploit first.
ARVIKA-augmented reality for development, production and service

Augmented reality (AR) is a form of human-machine interaction where information is presented in the field of view of an individual. ARVIKA, funded by the German Ministry of Education and Research, develops this technology and applications in the fields of development, production, and service in the automotive and aerospace industries, for power and processing plants and for machine tools and production machinery. Up to now, AR has only been a subject of individual research projects and a small number of application-specific industrial projects on a global scale. The current state of the art and the available appliances do not yet permit a product-oriented application of the technology. However, AR enables a new, innovative form of human-machine interaction that not only places the individual in the center of the industrial workflow, but also offers a high potential for process and quality improvements in production and process workflows. ARVIKA is primarily designed to implement an augmented reality system for mobile use in industrial applications. The report presents the milestones that have been achieved after a project duration of a full three years.
Microtome-free 3-dimensional confocal imaging method for visualization of mouse intestine with subcellular-level resolution.

BACKGROUND & AIMS The intrinsic opacity of mouse intestinal tissue prevents its evaluation by high-resolution, in-depth optical microscopy. Instead, intestinal tissue is usually sectioned to expose the interior domains of the mucosa and submucosa for microscopic examination. However, microtome sectioning can cause distortions and artifacts that prevent acquisition of an accurate view of the sample. We therefore attempted to develop a microtome-free 3-dimensional (3D) confocal imaging method for characterization of mouse intestine. METHODS We applied an optical-clearing solution, FocusClear, to permeate and reduce the opacity of mouse colon and ileum. Tissues were labeled with fluorescent probes and examined by confocal microscopy with efficient fluorescence excitation and emission in the FocusClear solution. The voxel-based confocal micrographs were processed with Amira software for 3D visualization and analysis. RESULTS Treatment of tissues with the optical-clearing solution improved photon penetration, resulting in the acquisition of images with subcellular-level resolution across the mucosa, submucosa, and muscle layers. Collectively, the acquired image stacks were processed by projection algorithms for 3D analysis of the spatial relations in villi, crypts, and connective tissues. These imaging technologies allowed for identification of spatiotemporal changes in crypt morphology of colon tissues from mice with dextran sulfate sodium-induced colitis as well as detection of transgenic fluorescent proteins expressed in the colon and ileum. CONCLUSIONS This new optical method for penetrative imaging of mouse intestine does not require tissue sectioning and provides a useful tool for 3D presentation and analysis of diseased and transgenic intestine in an integrated fashion.
A Generic Framework for Human Motion Recognition Based on Smartphones

In recent years, human motion recognition based on smartphones has gotten increasing attention in many fields such as mobile health, health tracking and pervasive computing. However, motion recognition performance can be easily affected by variation of phone orientations and positions. Different users have influence on recognition accuracy as well. Most of existing work focuses on one or two respects of above problems, or train different models for different phone positions and orientations. In this paper, we propose a generic framework for human motion recognition based on smartphones, which can effectively discriminate six daily motions regardless of device positions and orientations. We select a set of more robust and effective features to solve performance degradation problem caused by different phone positions, phone orientations and users. In experiments, we access our method using the dataset collected by three volunteers on Android smartphones. The experimental results show that the proposed feature extraction algorithm is better than most existing algorithms.
Synergetic Effects of Graphene and Nonfunctionalized Carbon Nanotubes Hybrid Reinforced Epoxy Matrix on Mechanical, Thermal and Wettability Properties of Nanocomposites

In this study we focused on the effect of Graphene Nanoplates (GNPs) and Nonfunctionalized Multi Wall Carbon Nanotubes (MWCNTs) hybrid nanofiller and its dispersion on mechanical, wettability, and thermal stability properties of epoxy nanocomposites. The epoxy resin was mixed with 0.5wt. % (GNPs-MWNTs) by direct mixing method using different (GNPs:MWNTs) ratio as (0:10, 1:9, 2.5:7.5, 5:5, 7.5:2.5, 9:1 and 10:0). The dispersionability of carbon nanofiller in epoxy nanocomposite samples was examined by FESEM. The results indicate that epoxy /GNPs significantly out-perform MWNTs additives. The superiority of GNPs in terms of mechanical properties improvement over MWNTs may be due to their high aspect ratio, improved nanofiller matrix adhesion/interlocking arising from their wrinkled surface, and their geometry (2D structure). The best improvements in mechanical properties was found at two mixing ratios of GNPs: MWNTs (5:5) and (9:1). The improved mechanical properties of epoxy/GNPs- MWNTs hybrid nanocomposite is related to the formation of 3-D hybrid architectures structure in epoxy matrix as confirmed by FESEM observations. The hydrophobicity of Epoxy/0.5 wt. % MWNTs is higher than that of epoxy/0.5wt. % GNPs, where contact angle of Epoxy/MWNTs is larger than that of epoxy/ 0.5wt. % GNPs and water absorption of Epoxy/ 0.5wt. % MWNTs is less than that for epoxy/ 0.5wt. % GNPs. Hydrophilicity of neat epoxy decreases by adding 0.5 wt. % GNPs-MWNTs with mixing ratio 2.5:7.5 where contact angles are changed from 43.5° to 79.5°. Thermogravimetric analysis results for neat epoxy, Epoxy/MWNTs, Epoxy/GNPs, and Epoxy/GNPs-MWNTs do not show any major influence on thermal stability of epoxy.
Evaluating semantic relatedness through categorical and contextual information for entity disambiguation

The number of entities in large-scale knowledge bases has been growing in recent years. The key issue to entity linking using a knowledge base such as Wikipedia is entity disambiguation. The objective of our proposing system is to disambiguate entities in documents and link entity mentions to their corresponding Wikipedia articles. To this end, our system ranks the set of candidate entities based on relatedness by utilizing semantic features derived from Wikipedia category hierarchies and articles. In addition, to reflect contextual information of Wikipedia, we utilize word embedding for refining the ranking result of candidate entities. Our experimental results show that these features have given good correlation with human rankings in candidate relatedness ranking and the combination of features has high disambiguation accuracy on news articles.
Transient tachypnea of newborn. Possible delayed resorption of fluid at birth.

DESPITE recent attempts to distinguish the multiple causes of neonatal respiratory distress, there remains a group of infants in whom none of the previously described disorders can be shown to exist. Over the past three years we have encountered eight infants who have much in common and who, therefore, probably constitute a previously undescribed syndrome. All but one have been full-term infants in whom respiratory distress, characterized chiefly by tachypnea, has occurred at or near the time of birth and persisted for several days with subsequent complete clearing. Their clinical course and the radiographic findings help to distinguish them from other infants with pneumonia, aspiration, heart failure, and congenital malformations. Description of Patients In none of the cases was there evidence of maternal infection or hemorrhage. One of the mothers had toxemia of pregnancy; another, excessive weight gain. Only one of the eight infants was delivered by cesarean section. There
The Future of Health Care in the United States

The U.S. government is involved in health care in various ways that include (1) providing services to veterans, (2) paying for care received by Medicare and Medicaid beneficiaries, (3) assuring quality through regulatory activity, (4) financing the discovery of medical breakthroughs, and (5) training members of the health workforce and assuring that the nation has an adequate supply of them. With the aging of the population, the role of the government in these endeavors will increase. This essay considers ways in which the health care of tomorrow will be affected by the intermingling of factors such as demography, epidemiology, economics, technology, globalization, and individual health behavior.
Modeling of toughness enhancement mechanisms in graphene nanocomposites

ABSTRACT The objective of this paper is to develop a mechanism-based theoretical model to explain fracture experiments conducted on nanographene platelet (NGP) reinforced thermoset polymer nanocomposite tested in pure Mode I and in mixed mode by the authors and other researchers. Remarkable improvement in fracture toughness, KIC (∼200%), and critical strain energy release rate, GIC (∼570%), was observed with only 0.5 wt% NGP addition to the EPON 862 polymer system. Interestingly, very large increase in ductility of the fracture specimens at peak load was observed with increasing NGP loading. Asymmetric four-point bend tests were also performed for three different mode mix (tan−1(KII/KI)) ratios (38°, 57°, and 89.5°). Significant enhancement in toughness as well as ductility for each mode mix case was observed with increasing NGP loading. Further, significant increases of 48% and 100% in delamination initiation toughness and resistance to crack propagation, respectively, were observed for 0.5-wt% NGP-reinforced IM7/EPON 862 unidirectional laminate. In this article, the reinforcement capacity of NGPs is explained through a length-scale based toughness enhancement mechanism, which is then employed to predict the critical length and orientation of nanoparticles for maximum fracture toughness improvement. It is envisioned that the application of this model could lead to significant toughness enhancement in composite laminates through (a) reduced intralaminar matrix cracks, (b) improved fiber/matrix interfacial toughening by controlling the size of nanoparticle growth on fuzzy fibers, and (c) improved delamination toughening as already demonstrated by the authors. For conclusive verification of our proposed model, there is a need for in-situ experiments to fully verify the nanoscale toughening effect by observing the process zone size near the tip of a nanoscale crack in a polymer thin film in-situ while it is being loaded, visualizing the brittle–ductile transition postulated by our theory and MD simulations. Work is currently underway in collaboration with the Air Force Research Laboratory to accomplish this objective.
Treatment of Endometrial Stromal Sarcoma With a Gonadotropin-Releasing Hormone Analogue

BACKGROUND: Endometrial stromal sarcoma can present management difficulties due to its lack of response to conventional chemotherapy and radiotherapy. Various hormonal therapies have been shown to reduce tumor volume in both primary and recurrent disease. CASE: A woman who underwent myomectomy was discovered to have a low-grade endometrial stromal sarcoma. Treatment with the gonadotropin-releasing hormone (GnRH) analogue triptorelin before surgery had produced reduction in uterine size. The woman developed tumor recurrence six months after definitive surgical treatment. The tumor enlarged rapidly during a 2-month period, with development of a right-sided hydronephrosis. Repeat administration of triptorelin was accompanied by resolution of the hydronephrosis and reduction in tumor volume. Biopsy results confirmed recurrent low-grade endometrial stromal sarcoma with moderate estrogen and progesterone receptor positivity. CONCLUSION: Control of progression of a recurrent endometrial stromal sarcoma was achieved with the GnRH analogue triptorelin. This is the first report in the English-language literature during a 30-year period of single-agent GnRH analogue being an effective treatment intervention in this context.
Assessment of social support in HIV-positive individuals attending a tertiary care center

Sir, Adult prevalence of human immunodeficiency virus (HIV) in India is 0.36%, amounting to approximately 2.5 million people living with HIV and acquired immunodeficiency syndrome. [1] Since the availability of Highly Active Anti-Retroviral Therapy HAART, improvement in quality of life (QOL) of patients has become a key issue in patient management. [2] A higher level of social support improves mental health, provides more days of vitality and, most importantly, better social support has been found to be associated with improved QOL. [3] In India, where 72.2% of the population lives in rural areas,[4] with joint families being more common than nuclear ones, it may prove to be a valuable tool along with HAART in the management of HIV-positive individuals. We present assessment of social support in such patients.
TALplanner: A Temporal Logic-Based Planner

TALplanner is a forward-chaining planner that utilizes domain-dependent knowledge to control search in the state space generated by action invocation. The domain-dependent control knowledge, background knowledge, plans, and goals are all represented using formulas in a temporal logic called tal, which has been developed independently as a formalism for specifying agent narratives and reasoning about them. In the Fifth International Artificial Intelligence Planning and Scheduling Conference planning competition, TALplanner exhibited impressive performance, winning the Outstanding Performance Award in the Domain-Dependent Planning Competition. In this article, we provide an overview of TALplanner
Wolman's disease. A rare lipidosis with adrenal calcification.

In 1956 Abramov, Schorr, andWolman from Israel described a 2-month-old female infant of PersianJewish extraction, whose parents were first cousins, who died from a lipidosis in which triglycerides and cholesterol were deposited in various tissues, and in whom the adrenals were extensively involved and diffusely calcified. In 1961 they reported an identical disease in two other sisters of the same family. Crocker et al. (1965) reported the first 3 cases of this disorder to be recognized in America. They were not related and were of widely different racial origin. The male patient in their report had a brother who died of an apparently similar disease. In 1966 the first case in Japan was described by Konno et al. in a 2month-old female infant who had 3 sibs, 2 of whom had succumbed after a clinically similar illness. In a review of the literature, Wolman et al. (1961) suggested that single, similarly affected, infants may have been reported as cases ofNiemannPick disease by Alexander (1946) from New Zealand and by Dienst and Hamperl (1927) from Austria. In a discussion on Gaucher's disease reported in the Scandinavian literature, Henschen (1926) described a 7-week-old infant with 'Niemann's' disease in which the adrenals were extensively involved, but calcification was not mentioned. Caffey (1961) illustrates the adrenal calcification in an infant who died of a disease of the 'NiemannPick' type. It seems probable that these are all cases of 'Wolman's' disease. This paper reports two further examples of this disorder; the first patient, a female infant of Irish descent, was diagnosed during life. The diagnosis was made in the second patient, an English boy, after a review of biopsy and necropsy material previously reported as an unclassified lipidosis.
Distribution of fibronectin on clonal cell lines of a rat mammary adenocarcinoma growing in vitro and in vivo at primary and metastatic sites.

With the use of a rat 13762 mammary adenocarcinoma tumor, we have examined the relationship between cellular fibronectin (FN) expression and ability to metastasize spontaneously to regional lymphatic and distant blood-borne sites. This model is based on the isolation and establishment of cell clones from primary parental tumor and from spontaneous metastases that show differing metastatic potentials when implanted s.c. into the mammary fat pads of syngeneic female Fischer 344/CRBL rats. Cellular FN expression was determined in tissue culture as well as primary and secondary tumor sites, utilizing: (a) indirect immunofluorescence microscopy with a specific anti-rat FN antibody (in vitro and in vivo grown cells); (b) competition radioimmunoassay for cell-released FN (in vitro grown cells); and (c) surface labeling by radioiodination-sodium dodecyl sulfate-polyacrylamide gel electrophoresis-autoradiography for cell surface-bound FN (in vitro grown cells). Tissue culture-grown parental tumor clones displayed FN at their cell surfaces. At confluency, they expressed higher quantities of FN at their peripheries and in fibrillar structures between adjacent cells and released greater amounts of this glycoprotein. Lung metastases-derived tumor clones released negligible amounts of FN by radioimmunoassay and failed to express detectable amounts of FN by indirect immunofluorescence and cell surface-labeling techniques. However, when parental tumor- and metastasis-derived clones of widely different metastatic potentials were carefully examined for FN expression and release, there was no obvious relationship between metastasis and FN expression or release in culture or display in tumors at primary or secondary sites. The results suggest that expression or release of FN per se is not a determinant of metastasis, although it may be a factor in certain steps of the metastatic sequence.
Automatic Test Case Generation for Orchestration Languages at Service Oriented Architecture

Service oriented architecture (SOA) is one of the latest software architectures. This architecture is created in direction of the business requirements and for removing the gap between softwares and businesses. The software testing is rising cost of activities in development software. SOA has different specifications and features proportion of the other software architectures. According to these features of the system, we cannot apply all approaches and methodologies of testing in the typical software systems for testing in the SOA systems, and there are need to specific procedures for testing the service oriented systems and/or change in the testing approaches. This document presents an approach for test cases generation automatically at the SOA system. First, this approach creates a control flow graph of BPEL file in the system and services related of the main service, WSIG file is used to create subgraphs of the related services. Then, the test cases create randomly of the primary test for graph in the generated system. Final, it tries to create test cases require to cover of the system graph through randomly generation and the genetic algorithms. This algorithm will compare with standard genetic algorithm and we will show the algorithm has performance better than the other algorithm.
