Visual Relationship Recognition via Language and Position Guided Attention

Visual relationship recognition, as a challenging task used to distinguish the interactions between object pairs, has received much attention recently. Considering the fact that most visual relationships are semantic concepts defined by human beings, there are many human knowledge, or priors, hidden in them, which haven’t been fully exploited by existing methods. In this work, we propose a novel visual relationship recognition model using language and position guided attention: language and position information are exploited and vectored firstly, and then both of them are used to guide the generation of attention maps. With the guided attention, the hidden human knowledge can be made better use to enhance the selection of spatial and channel features. Experiments on VRD [2] and VGR [1] show that, with language and position guided attention module, our proposed model achieves state-of-the-art performance.
Pulmonary Circulation | April-june 2012 | Vol 2 | No 2 170 Mesenchymal Stem Cell-mediated Reversal of Bronchopulmonary Dysplasia and Associated Pulmonary Hypertension

Research Ar ticle Bronchopulmonary dysplasia (BPD) is a complex chronic lung disease (CLD) with multifactorial etiology, characterized by the arrest of alveolar and vascular growth associated with inflammation and parenchymal fibrosis. Historically, oxygen toxicity and ventilator-induced injury have been the prerequisites for BPD in premature infants born at less than 28-32 weeks gestation with respiratory distress syndrome, but BPD may also occur in immature infants with few signs of initial lung injury. Approximately one in four infants with moderate-to-severe BPD develops pulmonary hypertension (PH) ABSTRACT Clinical trials have failed to demonstrate an effective preventative or therapeutic strategy for bronchopulmonary dysplasia (BPD), a multifactorial chronic lung disease in preterm infants frequently complicated by pulmonary hypertension (PH). Mesenchymal stem cells (MSCs) and their secreted components have been shown to prevent BPD and pulmonary fibrosis in rodent models. We hypothesized that treatment with conditioned media (CM) from cultured mouse bone marrow-derived MSCs could reverse hyperoxia-induced BPD and PH. Newborn mice were exposed to hyperoxia (FiO 2 =0.75) for two weeks, were then treated with one intravenous dose of CM from either MSCs or primary mouse lung fibroblasts (MLFs), and placed in room air for two to four weeks. Histological analysis of lungs harvested at four weeks of age was performed to determine the degree of alveolar injury, blood vessel number, and vascular remodeling. At age six weeks, pulmonary artery pressure (PA acceleration time) and right ventricular hypertrophy (RVH; RV wall thickness) were assessed by echocardiography, and pulmonary function tests were conducted. When compared to MLF-CM, a single dose of MSC-CM-treatment (1) reversed the hyperoxia-induced parenchymal fibrosis and peripheral PA devascularization (pruning), (2) partially reversed alveolar injury, (3) normalized lung function (airway resistance, dynamic lung compliance), (4) fully reversed the moderate PH and RVH, and (5) attenuated peripheral PA muscularization associated with hyperoxia-induced BPD. Reversal of key features of hyperoxia-induced BPD and its long-term adverse effects on lung function can be achieved by a single intravenous dose of MSC-CM, thereby pointing toward a new therapeutic intervention for chronic lung diseases. by inflammation and endothelial dysfunction, and perpetuated through alveolar hypoxia. Importantly, the occurrence of PH in BPD is not only an epiphenomenon or minor secondary event, but appears to greatly increase mortality (estimated death rate is 47% two years after diagnosis of PH). [6] Moreover, with an increasing percentage of extremely immature newborns surviving in the post-surfactant era, BPD is one of the most …
Hyperion, a space-based imaging spectrometer

The Hyperion Imaging Spectrometer was the first imaging spectrometer to routinely acquire science-grade data from Earth orbit. Instrument performance was validated and carefully monitored through a combination of calibration approaches: solar, lunar, earth (vicarious) and atmospheric observations complemented by onboard calibration lamps and extensive prelaunch calibration. Innovative techniques for spectral calibration of space-based sensors were also tested and validated. Instrument performance met or exceeded predictions including continued operation well beyond the planned one-year program.
Comparing Languages for Enterprise Modeling using a Language Quality Framework

: Statoil have recently wanted to standardize enterprise modeling language for sense-making and communication. To perform the evaluation, a generic framework for assessing the quality of models and modeling languages was specialized to the needs of the company. Five different modeling languages were evaluated according to the specialized criteria. The work illustrates the practical utility of the overall framework, where language quality features are looked upon as means to enable the creation of models of high quality. It also illustrates the need for specializing this kind of general framework based on the requirements of the specific organization
The Affinity of Elongated Membrane-Tethered Ligands Determines Potency of T Cell Receptor Triggering

T lymphocytes are important mediators of adoptive immunity but the mechanism of T cell receptor (TCR) triggering remains uncertain. The interspatial distance between engaged T cells and antigen-presenting cells (APCs) is believed to be important for topological rearrangement of membrane tyrosine phosphatases and initiation of TCR signaling. We investigated the relationship between ligand topology and affinity by generating a series of artificial APCs that express membrane-tethered anti-CD3 scFv with different affinities (OKT3, BC3, and 2C11) in addition to recombinant class I and II pMHC molecules. The dimensions of membrane-tethered anti-CD3 and pMHC molecules were progressively increased by insertion of different extracellular domains. In agreement with previous studies, elongation of pMHC molecules or low-affinity anti-CD3 scFv caused progressive loss of T cell activation. However, elongation of high-affinity ligands (BC3 and OKT3 scFv) did not abolish TCR phosphorylation and T cell activation. Mutation of key amino acids in OKT3 to reduce binding affinity to CD3 resulted in restoration of topological dependence on T cell activation. Our results show that high-affinity TCR ligands can effectively induce TCR triggering even at large interspatial distances between T cells and APCs.
Quiescent Saccharomyces cerevisiae forms telomere hyperclusters at the nuclear membrane vicinity through a multifaceted mechanism involving Esc1, the Sir complex, and chromatin condensation

Upon quiescence entry, yeast cells assemble telomere hyperclusters. These structures localize to the nuclear membrane in an Esc1-dependent manner and assemble through the combined action of the Sir complex, deacetylation of H4K16, the binding of the linker histone H1, and condensin.
Lightweight modular staging: a pragmatic approach to runtime code generation and compiled DSLs

Software engineering demands generality and abstraction, performance demands specialization and concretization. Generative programming can provide both, but the effort required to develop high-quality program generators likely offsets their benefits, even if a multi-stage programming language is used. We present lightweight modular staging, a library-based multi-stage programming approach that breaks with the tradition of syntactic quasi-quotation and instead uses only types to distinguish between binding times. Through extensive use of component technology, lightweight modular staging makes an optimizing compiler framework available at the library level, allowing programmers to tightly integrate domain-specific abstractions and optimizations into the generation process. We argue that lightweight modular staging enables a form of language virtualization, i.e. allows to go from a pure-library embedded language to one that is practically equivalent to a stand-alone implementation with only modest effort.
DECOMPOSITION CHARACTERISTICS AND NUTRIENT RELEASE RULES OF MAIZE STRAW UNDER DIFFERENT RETURNING AMOUNTS

The decomposition and nutrient release of maize (Zea mays L.) straw under the four returning amounts of 10.0 g (CR1), 30.0 g (CR3), 50.0 g (CR5), and 70.0 g (CR7) were studied by nylon mesh bag method, exploring the decomposition characteristics and nutrient releases rules of maize straw, and providing a theoretical basis of rational use of straw resources and nutrient resources management. The results showed that decomposition and the nutrients release of straw are fast in the early stage (0-20 days) and slow in the late stage (20-100 days). In the first 20 days, the C/N ratio of the straw decreased the fastest, and the decomposition and nutrient release was the fastest. At the end of the experiment, the C/N ratio is relatively stable, the characteristics of decomposition rate and P and K releases rules was CR3 > CR5 = CR7 > CR1, the C and N release rate rules were CR3 = CR5 > CR7 > CR1; the release order of the different nutrients was K > P > N > C; the decomposition and nutrient release of CR3 was the fastest. In summary, a reasonable amount of returning promotes straw decomposition and nutrient release, which are conducive to the rational use of straw resources, and put forward measures of nutrient resource
Relationship of maximum aerobic power output to productivity and absenteeism of East African sugar cane workers

Davies, C. T. M. (1973). British Journal of Industrial Medicine,30, 146-154. Relationship of maximum aerobic power output to productivity and absenteeism of East African sugar cane workers. The relationship of the physiological responses to laboratory exercise on an upright bicycle ergometer and predicted maximum aerobic power output (V̇O2max) to daily and season output has been investigated in 78 cane cutters aged 18 to 50 years working on the Kilombero sugar estate, Tanzania. The results showed that the (V̇O2max) was independent of absolute productivity in terms of kilotons of cane cut per season but positively correlated (r = + 0·46) with daily output. There was a small but significant (r = - 0·32, P < 0·001) negative association of V̇O2max with the number of days that an individual voluntarily absented himself from the cane fields. The importance of these findings to the selection and training of personnel for the cane-cutting industry are discussed. It was suggested that the industry might consider the introduction of a simple exercise (step) test together with a medical examination and simple anthropometric measurements at the time of recruitment of workers at the beginning of the season.
Structural characterisation of BaTiO3 thin films deposited on SrRuO3/YSZ buffered silicon substrates and silicon microcantilevers

We report on the progress towards an all epitaxial oxide layer technology on silicon substrates for epitaxial piezoelectric microelectromechanical systems. (101)-oriented epitaxial tetragonal BaTiO3 (BTO) thin films were deposited at two different oxygen pressures, 5.10−2 mbar and 5.10−3 mbar, on SrRuO3/Yttria-stabilized zirconia (YSZ) buffered silicon substrates by pulsed laser deposition. The YSZ layer full (001) orientation allowed the further growth of a fully (110)-oriented conductive SrRuO3 electrode as shown by X-ray diffraction. The tetragonal structure of the BTO films, which is a prerequisite for the piezoelectric effect, was identified by Raman spectroscopy. In the BTO film deposited at 5.10−2 mbar strain was mostly localized inside the BTO grains whereas at 5.10−3 mbar, it was localized at the grain boundaries. The BTO/SRO/YSZ layers were finally deposited on Si microcantilevers at an O2 pressure of 5.10−3 mbar. The strain level was low enough to evaluate the BTO Young modulus. Transmission electron microscopy (TEM) was used to investigate the epitaxial quality of the layers and their epitaxial relationship on plain silicon wafers as well as on released microcantilevers, thanks to Focused-Ion-Beam TEM lamella preparation.
Comparative Evaluation of Different Classification Techniques for Masquerade Attack Detection

Masquerade detection is a special type of intrusion detection problem. Effective and early intrusion detection is a crucial basis for computer security. Although of considerable work has been focused on masquerade detection for more than a decade, achieving a high level of accuracy and a comparatively low degree of false alarm rate is still a big challenge. In this paper, we present an extensive empirical study in the area of user behaviour profiling-based masquerade detection using six of different existed machine learning methods in Azure Machine Learning (AML) studio. In order to surpass previous studies on this subject, we used four free and publicly available datasets with seven data configurations are implemented from them. Moreover, eight well-known masquerade detection evaluation metrics are used to assess methods performance against each data configuration. Finally, intensive quantitative and ROC curves analyses of results are provided at the end of this paper.

The Contribution of Maternal-Fetal Attachment: Taegyo, Maternal Fatigue and Social Support during Pregnancy

Purpose: Maternal-fetal attachment in a pregnant woman is important for her health and for her child's emotional stability. This study was done to identify the contribution of maternal fatigue, social support, and Taegyo to maternal-fetal attachment based on a survey of pregnant women. Methods: The study was a descriptive correlation study. Participants were 211 from two women's health clinic centers. Data were analyzed using t-test, ANOVA, Pearson correlation coefficients and stepwise multiple regression. Results: Mean scores for maternal-fetal attachment, Taegyo, maternal fatigue, and social support were 93.74 (range 25-125), 64.76 (17-85), 24.12 (10-40), and 54.43 (22-132), respectively. There were sig- nificant differences in maternal-fetal attachment according to parity, breast feeding experience, and putting prenatal education into practice. Multiple regression analysis showed that the key determinants of maternal-fetal attachment, were Taegyo (β = .67), maternal fatigue (β = .21), and social support (β = .13), and these explained 55% of the total variance of attachment. Conclusion: The results suggest a need to encourage Taegyo in prenatal management program and provide methods for fatigue resolution and promotion of social support.
AMELIORATING EFFECT OF GINGER EXTRACT (ZINGIBER OFFICINALE ROSCOE) ON LIVER MARKER ENZYMES, LIPID PROFILE IN ALUMINIUM CHLORIDE INDUCED MALE RATS

Nowadays, aluminium (Al) exposure has been increasing and it has the potential to be toxic in animal and humans. In recent years, ginger has become a subject of interest because of its beneficial effects on human health. The purpose of the present study to investigate the effect of ginger extract on serum biochemical parameters of aluminium chloride (AlCl3) induced male rats. 24 Wistar rats (6 in each group) distributed into 4 groups. Control group received distilled water as vehicle; In E1 group, animal received AlCl3 orally (100 mg/kg bw), E2 group received AlCl3 (100 mg/kg bw) and simultaneously with ginger extract (50 mg/kg bw) and E3 group received ginger extract alone (50 mg/kg bw) for 60 days. At the end of the experimental period, blood samples were collected for separating the serum for biochemical analyses. The results showed that oral administration of aluminium revealed a significant increase in the levels of serum glucose, total protein, globulin, albumin, urea, uric acid, creatinine, lipid profile and serum aspartate aminotransferase (AST), alanine aminotransferase (ALT) and alkaline phosphatase (ALP) and no change was noted in bilirubin. The extract of ginger decreased the activities serum levels of AST, ALT, ALP, lipid profile and all the parameter studied. It was concluded that the consumption of ginger protects the liver and kidney against the Aluminium toxicity. In addition, ginger is capable of improving hyperlipidemia and the impaired kidney functions.
Dynamic behavior of closed grinding systems and effective PID parameterization

The object of the present study is to investigate the dynamic of closed circuit cement mills and based on that to tune robust PID controllers applied to three actual installations. The model that has been developed, consisting of integral part, time delay and a first order filter, is based exclusively on industrial data sets collected in a period more than one year. The model parameters uncertainty is also assessed varying from 28% to 36% as the gain is concerning and 34% to 42% as regards the time delay. As significant sources of model uncertainty are determined the grinding of various cement types in the same cement mill and the decrease of the ball charge during the time. The Internal Model Control (IMC) and M - Constrained Integral Gain Optimization (MIGO) methods are utilized to adjust the controller parameters. Specially by implementing the MIGO technique robust controllers are built deriving a daily average IAE 2.3-3% of the set point value. Due to the high flexibility and effectiveness of MIGO, the controllers can be parameterized by taking into account the cement type ground and the power absorbed. Subsequently the attenuation of main uncertainties leads to improvement of the regulation performance.
Efficient variants of the ICP algorithm

The ICP (Iterative Closest Point) algorithm is widely used for geometric alignment of three-dimensional models when an initial estimate of the relative pose is known. Many variants of ICP have been proposed, affecting all phases of the algorithm from the selection and matching of points to the minimization strategy. We enumerate and classify many of these variants, and evaluate their effect on the speed with which the correct alignment is reached. In order to improve convergence for nearly-flat meshes with small features, such as inscribed surfaces, we introduce a new variant based on uniform sampling of the space of normals. We conclude by proposing a combination of ICP variants optimized for high speed. We demonstrate an implementation that is able to align two range images in a few tens of milliseconds, assuming a good initial guess. This capability has potential application to real-time 3D model acquisition and model-based tracking.
Determinants of Route Choice and Value of Traveler Information

Drivers receive value from traveler information in several ways, including the ability to save time, but perhaps more important is the value of certainty as it affects other personal, social, safety, or psychological factors. This information can be economically valued. The benefit of reduction in driver uncertainty when information is provided at the beginning of the trip is the main variable measured in this research. User preferences for routes were assessed as a function of the presence and accuracy of information while controlling for other trip and route attributes. Data were collected in a field experiment in which 113 drivers, given real-time travel time information with varying degrees of accuracy, drove four alternative routes between a preselected origin-destination pair in the Twin Cities, Minnesota, metropolitan area. Ordinary regression, multinomial, and rank-ordered logit models produced estimates of the value of information with some variation. Results showed that travelers were willing to pay up to $1 per trip for pretrip travel-time information. The value of information is higher for commute and event trips and when congestion on the usual route is heavier. The accuracy of the traveler information was also a crucial factor. Travelers will not pay for information unless they perceive it to be accurate. Most travelers (70%) prefer that such information be provided free by the public sector, whereas some (19%) believe that it is better for the private sector to provide such service at a charge.
Discrete Variational Autoencoders

Probabilistic models with discrete latent variables naturally capture datasets composed of discrete classes. However, they are difficult to train efficiently, since backpropagation through discrete variables is generally not possible. We present a novel method to train a class of probabilistic models with discrete latent variables using the variational autoencoder framework, including backpropagation through the discrete latent variables. The associated class of probabilistic models comprises an undirected discrete component and a directed hierarchical continuous component. The discrete component captures the distribution over the disconnected smooth manifolds induced by the continuous component. As a result, this class of models efficiently learns both the class of objects in an image, and their specific realization in pixels, from unsupervised data, and outperforms state-of-the-art methods on the permutation-invariant MNIST, Omniglot, and Caltech-101 Silhouettes datasets.
Cerebrovascular Events in Systemic Lupus Erythematosus: Diagnosis and Management

Stroke is a major cause of morbidity, mortality and disability in systemic lupus erythematosus (SLE). Patients with SLE have a two-fold increase in the risk of stroke with younger patients (ie, less than 50 years of age) having an ever-higher risk (up to 10-fold). Although the prognosis of SLE has improved, mortality due to cerebrovascular events (CVE) remains unchanged. Cerebrovascular disease may be directly attributed to the disease per se, as a manifestation of neuropsychiatric SLE, or be the result of traditional cardiovascular risk factors accompanying the disease. Elucidation of the underlying mechanism(s) of CVE is essential as it may guide the type of therapy (ie, antithrombotic or anticoagulant therapy versus immunosuppressive). Strokes attributed to lupus usually occur early in the course of the disease and are often accompanied by evidence of activity in other organs; those related to antiphospholipid antibodies can occur at any time, in patients with either active or inactive SLE. In this review, we discuss the epidemiology, work-up, management and primary prevention of CVE in patients with lupus. In view of the effectiveness of thrombolysis, physicians need to educate lupus patients and their families for the early recognition of the signs of stroke and the need to seek prompt attention. To this end acronyms, such as FAST (Facial drooping, Arm weakness, Speech difficulties and Time to call emergency service) can be used as a mnemonic to help detect and enhance responsiveness to the needs of a person having a stroke.
