Horror video recognition based on fuzzy comprehensive evolution

Technique for horror video recognition is important for its application in web content filtering and surveillance, especially for preventing children from being threaten. In this paper, a novel horror video recognition algorithm based on fuzzy comprehensive evolution model is proposed. Three low-level video features are extracted as typical features, and they are video key-light, video colour energy and video rhythm. Analytic Hierarchy Process (AHP) is adopted to estimate the weights of extracted features in fuzzy evolution model. Horror evaluation (membership function) is on shot scale and it is constructed based on the knowledge that videos which share the same affective have similar low-level features. K-Means algorithm is implemented to help finding the most representative feature vectors. The experimental results demonstrate that the proposed approach has good performance in recognition precision, recall rate and F1 measure.
The Dynamic Aging Mind

The conception of the aging mind that emerged from behavioral and structural imaging studies portrayed the mind as a victim of passive deterioration and decline with age, with a few domains of preserved function. The advent of functional neuroimaging has demonstrated that the aging brain is an adaptive and plastic structure that responds dynamically to cognitive challenge and structural deterioration—thus, fundamentally changing views of cognitive aging. In addition, a neural theory of the aging mind based on behavioral data—the dedifferentiation view of cognitive aging—was largely confirmed when neuroimaging technology became available to test it. We argue that functional neuroimaging has advanced cognitive aging theories by creating a stronger emphasis on compensatory mechanisms related to brain plasticity and potential reorganization as evidenced by the resurgence of interest and research in cognitive training research designed to improve cognition through enhancement of neural structures or reorganization of functional circuitry.
Conflict-Aware Network State Updates in SDN

In SDN (Software-Defined Networks), applications are granted the ability to control and manage networks, such as routing, access control, and load balance, which is considered one of the most significant characters of SDN. However, these concurrent applications are lack of interactions when they operate on overlapping portions of the traffic and introduce a critical challenge of potentially conflicting flow rules (including match fields and actions). When their actions are dropping, forwarding, or diverting to the controller, these kinds of flow rule conflicts are inherent and arduous, and there exist no appropriate compositional methods of resolving them. Under the circumstances, the paper proposes a general model of abstract network states where different applications can own their different network views. When conflicting rules are detected, the model provides new network states for applications by composing original network states and conflicting rules. Therefore, applications do not need to handle underlying conflicting rules and just achieve the latest network states to install flow rules correctly.
Advances in viscous vortex methods—meshless spatial adaption based on radial basis function interpolation

Vortex methods have a history as old as finite differences. They have since faced difficulties stemming from the numerical complexity of the Biot–Savart law, the inconvenience of adding viscous effects in a Lagrangian formulation, and the loss of accuracy due to Lagrangian distortion of the computational elements. The first two issues have been successfully addressed, respectively, by the application of the fast multipole method, and by a variety of viscous schemes which will be briefly reviewed in this article. The standard method to deal with the third problem is the use of remeshing schemes consisting of tensor product interpolation with high‐order kernels. In this work, a numerical study of the errors due to remeshing has been performed, as well as of the errors implied in the discretization itself using vortex blobs. In addition, an alternative method of controlling Lagrangian distortion is proposed, based on ideas of radial basis function (RBF) interpolation (briefly reviewed here). This alternative is formulated grid‐free, and is shown to be more accurate than standard remeshing. In addition to high‐accuracy, RBF interpolation allows core size control, either for correcting the core spreading viscous scheme or for providing a variable resolution in the physical domain. This formulation will allow in theory the application of error estimates to produce a truly adaptive spatial refinement technique. Proof‐of‐concept is provided by calculations of the relaxation of a perturbed monopole to a tripole attractor. Copyright © 2005 John Wiley & Sons, Ltd.
Circulating Alanine Disposal in Diabetes Mellitus

Alanine was selected for study as a representative circulating glucose precursor in relation to the question of the source of the excess circulating glucose in diabetes mellitus. U-l4C alanine and U-14C glucose infusions were given to healthy subjects and to subjects with untreated mild maturity, severe maturity, and juvenile diabetes. Comparative studies after a 24-hour fast were made in healthy and in mildly diabetic subjects. The alanine production rate was unaltered by fasting or diabetes. The glucose production rate was unaltered by fasting but increased in diabetes in relation to the severity of the disease. The fractions of alanine-to-glucose and of glucose-from-alanine were increased by fasting. The effect of diabetes was different. The fraction of alanine-to-glucose was much less in mild maturity diabetes than in health, and it was increased only in juvenile diabetes. In all the diabetic groups the glucose-from-alanine fraction was much less than in health. In every group the change in the alanine oxidation rate was reciprocal to that in the alanine-derived glucogenesis rate. The results are consistent with the possibility that the principal source of the excess circulating glucose in diabetes is glycogen.
Beneficial Effects of a Novel IH636 Grape Seed Proanthocyanidin Extract in the Treatment of Chronic Pancreatitis

Oxygen-derived free radicals mediate tissue damage in acute and chronic pancreatitis. Low levels of natural antioxidants in pancreatitis indicate their increased utilization as scavengers of free radicals. Combination therapy with selenium, β-carotene, methionine, and vitamins C and E are known to improve symptoms of chronic and recurrent pancreatitis. This, however, requires many tablets to be taken daily, which is impractical and may reduce compliance. Three patients with chronic pancreatitis (two with a history of alcohol excess and one idiopathic) are reported. Treatment with narcotic analgesics and pancreatic enzyme supplements had failed to control their symptoms. The addition of a commercially available IH636 grape seed proanthocyanidin extract (commercially known as ActiVin) to their treatment regimen led to a reduction in the frequency and intensity of abdominal pain as well as resolution of vomiting in 1 patient.
Inventory quality control in clinical engineering: A Lean Six Sigma approach

Medical equipment inventory control is important for any hospital. Its measurement and management directly affects healthcare providers' decisions about budgets, administration and maintenance. In this paper the authors present a case study, conducted at Albert Einstein Hospital which uses both Six Sigma and LEAN methodology/tools to improve the inventory control over critical medical equipments. The Six Sigma philosophy aims to diminish the errors committed, avoiding rework while LEAN aims at reducing all form of losses and wastes in the manufacturing process. Significant results were attained, increasing the selected indicator (complete forms) from 62,6% to 99,4%, which benefit both the hospital's management as well as the patient's level of care.
Evaluating Pointing Errors on Ergodic Capacity of DF Relay-Assisted FSO Communication Systems

Ergodic capacity of decode-and-forward (DF) relay-assisted free-space optical (FSO) communication systems when line of sight is available is analyzed over gamma-gamma fading channels with pointing errors. Novel closed-form approximate ergodic capacity expression is obtained in terms of the H-Fox function for a 3-way FSO communication system when the α-μ distribution to efficiently approximate the probability density function (PDF) of the sum of gamma-gamma with pointing errors variates is considered. Moreover, we present a novel asymptotic expression at high signal-to-noise ratio (SNR) for the ergodic capacity of DF relay-assisted FSO systems. The main contribution in this work lies in an in-depth analysis about the impact of pointing errors on the ergodic capacity for cooperative FSO systems. In order to maintain the same performance in terms of capacity, it is corroborated that the presence of pointing errors requires an increase in SNR, which is related to the fraction of the collected power at the receive aperture, i.e. A0. Simulation results are further demonstrated to confirm the accuracy and usefulness of the derived results.
Exercise Intensity and Pacing Strategy of Cross-country Skiers during a 10 km Skating Simulated Race

The aim of this study was to observe the cardiovascular demands by monitoring the heart rate (HR) and the pacing strategy by evaluating the speed during a simulated cross-country skiing race. Eleven skiers (16.45 ± 1.67 yrs; 21.32 ± 2.03 kg m–2; 72.35 ± 4.69 mL min–1 kg–1) competed in a 10km event divided into four laps. The HR profile was classified into four intensity zones. The skiers spent 66.84 ± 23.64% and 31.82 ± 23.77% of the total time above 90% and at 80 – 90% of the HRmax respectively, whereas the lower zones were negligible. During the event, a progressive increase in intensity was observed: HRmean raised by 2.42% in the last versus the first lap (p < 0.001). The skiers decreased their speed in the second (p = 0.017) and the third laps (p < 0.001) compared to with the first lap. In the fourth lap the skiers increased the speed slightly but without statistical difference. The speed maintained by the skiers resulted in the adoption of a reverse J-shaped pacing strategy.
Effects of hot-carrier stress on the performance of CMOS Low Noise Amplifier

The effects of DC hot-carrier stress on the performance of a CMOS Low Noise Amplifier (LNA) are investigated. It was observed that the main effects caused by stress on the NMOSFETs in the LNA are a decrease of the transconductance g/sub m/ and an increase of the output conductance g/sub ds/. As a result of these changes, the power gain of the amplifier S/sub 21/, input matching S/sub 11/ and output matching S/sub 22/ are deteriorated. The linearity of the LNA improved after stress and this is believed to be due to the improvement in the linearity of the I-V characteristics of the transistors in the circuit at the particular biasing points the measurements were made. The noise figure of the circuit also increases after hot carrier stress which is believed to be due to increase in channel thermal noise caused by hot carriers.
Metabolites in ventricular cerebrospinal fluid detected by proton magnetic resonance spectroscopic imaging

Normally, ventricular cerebrospinal fluid (CSF) contains low levels of all metabolite signals on proton magnetic resonance spectroscopic imaging (MRSI). We present here three cases (two with seizure disorders, one with a central nervous system lymphoma) who presented with unusually elevated CSF signals on MRSI. Based on chemical shifts and in vitro studies (in one case), the signals were assigned to propan‐1,2‐diol (PD), acetone, and lactate, respectively. These compounds were either exclusively, or more readily, detected in CSF than in brain. Proton MRSI conveniently screens both brain and CSF for abnormal metabolism simultaneously. J. Magn. Reson.

Preparation of Visible-Light Responsive Photocatalyst (Bi20TiO32) and Its Photocatalytic Activity for Degrading Organic Pollutants

A novel photocatalyst (Bi20TiO32) was synthesized by chemical solution decomposition (CSD) and it was calcined at the temperature of 300 oC. It exists in nanosheets with a diameter around 90 nm. The as-prepared Bi20TiO32 is visible-light responsive (up to 500nm in wavelength) without sacrificing its ability for absorbing UV light. The specific activity of Bi20TiO32 is higher than anatase TiO2 under the same sunlight irradiation condition. It has strong adsorption ability that it can oxidize organics directly by its holes, and it can also degrade organics by •OH. The photocatalytic mechanism of Bi20TiO32 is the combined effect of both holes and •OH radicals.
Waves: a model of collective learning

Collective learning considers how agents, in a community sharing a learning purpose, may benefit from exchanging hypotheses and observations to learn efficiently as a community as well as individuals. The community forms a communication network and each agent has access to observations. We address the question of a protocol, i.e. a set of agent's behaviours, which guarantees the hypotheses retained by the agents take into account all the observations in the community. We present and investigate the protocol WAVES which displays such a guarantee in a turn-based scenario: at the beginning of each turn, agents collect new observations and interact until they all reach this consistency guarantee. We investigate and experiment WAVES on various network topologies and various experimental parameters. We present results on learning efficiency, in terms of computation and communication costs, as well as results on learning quality, in terms of predictive accuracy for a given number of observations collected by the community.
Fluconazole-containing agar Sabouraud dextrose plates are not useful when screening for susceptibility in Candida albicans.

OBJECTIVE Fluconazole is an alternative for candidemic patients who are not critically ill. Fluconazole is mainly fungistatic and does not completely inhibit visual Candida albicans growth. We studied the usefulness of fluconazole-containing Sabouraud dextrose agar plates for detecting susceptibility to fluconazole in C. albicans. METHODS Adjusted inocula of 19 isolates were transferred directly onto fluconazole-containing Sabouraud dextrose plates (concentrations ranging from 0.125 mg/L to 128 mg/L). The fluconazole MIC in fresh isolates and after growth on the fluconazole-containing plate at 128 mg/L was recorded following the EUCAST EDef 7.2 guidelines. Then isolates were classified according to their degree of trailing production, based on microdilution procedure. RESULTS All isolates were able to grow on all fluconazole-containing plates, even those isolates susceptible to fluconazole. In fact, we selected isolates with different degrees of trailing based on microdilution procedures. 50% of isolates classified as heavy trailers, 35.71% as moderate trailers, and 14.28% as slight trailers. CONCLUSIONS The use of fluconazole-containing Sabouraud dextrose agar plates was not a reliable method to detect fluconazole susceptibility in C. albicans isolates; growth of the isolates was a trailing effect rather than true resistance.
Comfort and Confidence Levels of Health Care Professionals Providing Pediatric Palliative Care in the Intensive Care Unit

ABSTRACT Most childhood deaths that occur in the hospital happen in the pediatric intensive care unit. Providing pediatric palliative care in the intensive care unit comes with unique challenges due to the acute care, curative and often medically aggressive focus of these settings. In this study, 190 PICU health care professionals reported on their comfort and confidence in providing palliative care. Findings indicate that professionals report only a moderate level of comfort and confidence in this type of care in the pediatric ICU. For physicians and nurses, comfort and confidence was significantly higher for those who had practiced 8 years or more. Practitioners reported less comfort in providing psychosocial care. Implications for the social work role on the interdisciplinary team and suggestions for future research are discussed.
Analysis of Trends of Sleep-Related Breathing Disorders in Patients with Systemic Essential Hypertension

Background: Studies have revealed a strong link between sleep-related breathing disorders and essential hypertension. However, the trends of sleep-disordered breathing in hypertensive patients have not been analyzed frequently. Methods: In this prospective, single-center and observational study, random patients with systemic essential hypertension, who were visiting GSVM Medical College, Kanpur, India between December 2012 and July 2014, were selected. After obtaining informed consent, patients were analyzed for symptoms of sleep-disordered breathing and Epworth Sleepiness Scale. Subsequently, all patients underwent overnight polysomnography to estimate the events of apnea and hypopnea. Observed data were compared between stage I and stage II hypertensive patients. Results: A total of 51 patients (age: 45.7 ± 13.43 years), comprising 36 stage I hypertensives and 15 stage II hypertensives, were enrolled in the study. About 47% of these patients displayed no symptoms of sleep-disordered breathing. Compared to stage I hypertensives, higher percentage of stage II hypertensives reported excessive day time sleepiness. Sleep latency time and sleep architecture were comparable between stage I and stage II hypertensives. Stage II hypertensives displayed shorter total sleep time and higher snore time than stage I hyper-tensives. Apnea Hypopnea Index (AHI) values increased with the severity of hypertension. Nocturnal oxygen desaturation was present in 25.0% and 53.3% of stage I and II hypertensives respectively. Mean lowest oxygen saturation was lower and the mean C-reactive protein levels were higher in stage II hypertensives as compared to stage I hypertensives. The mean C-reactive protein levels increased with increasing AHI scores, while the mean lowest oxygen saturation decreased with increasing AHI scores. Conclusion: Almost half of the hypertensives patients reported no symptoms of sleep-disordered breathing. Sleep-disordered breathing was more common and was more severe in majority of patients with stage II hypertension as compared to that in patients with stage I hypertension.
Moschamine inhibits proliferation of glioblastoma cells via cell cycle arrest and apoptosis

Glioblastoma is the most common and most malignant primary brain tumor with a median survival of 15 months. Moschamine is an indole alkaloid that has a serotoninergic and cyclooxygenase inhibitory effect. In this study, we sought to determine whether moschamine could exert cytotoxic and cytostatic effects on glioma cells in vitro. Moschamine was tested for toxicity in zebrafish. We investigated the effect of moschamine on U251MG and T98G glioblastoma cell lines. Viability and proliferation of the cells were examined with trypan blue exclusion assay, 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay, and the xCELLigence system. Apoptosis (annexin–propidium iodide), cell cycle, and CD24/CD44/CD56/CD15 expression were tested with flow cytometry. Treatment with moschamine significantly reduced cell viability in both cell lines tested. Induction of cell death and cell cycle arrest was confirmed with flow cytometry in both cell lines. After treatment with moschamine, there was a dose-dependent decrease in CD24 and CD44 expression, whereas there was no change in CD56 and CD15 expression in T98G cell line. The zebrafish mortality on the fifth post-fertilization day was zero even for 1 mM of moschamine concentration. The treatment of glioblastoma cell lines with moschamine may represent a novel strategy for targeting glioblastoma.
Peculiarities of Biomechanical Properties of Ocular Tissue in Keratoconus

Considerable achievements having been recently made in modern diagnostics and treatment of keratoconus have not diminished the urgency of the given problem as the traditional views of the pathogenesis of keratoconus do not always allow to struggle effectively with this difficult and continuously progressing disease. The objective of the research was to study the peculiarities of biomechanical properties of the cornea in keratoconus. Materials and methods. The article presents the analysis of studying biomechanical properties of the cornea in keratoconus. 44 patients (88 eyes) with keratoconus and emmetropic refraction were examined. To calculate biomechanical indicators of the cornea there was carried out the comparative analysis between the measurements obtained with the use of several methods in the same patients, namely the Oculus Pentacam-Scheimpflug imaging device by a standard technique and the indicators calculated using the method proposed by us and the device for in vivo estimation of corneal rigidity. Results. Considerable advantages of using the developed method and the device for estimation of corneal rigidity in vivo in comparison with keratotopography on the Oculus Pentacam-Scheimpflug camera were registered which allowed us not only to reveal the presence of biomechanical disorders of the cornea, but also to differentiate their character. To describe the degree of changes in biomechanical properties of the cornea in vivo the coefficient of corneal rigidity was developed. Conclusions. Loading tests allow receiving more exact information on biomechanical properties of the cornea in comparison with standard researches on the Oculus Pentacam-Scheimpflug camera.
Rgt1p of Saccharomyces cerevisiae, a key regulator of glucose-induced genes, is both an activator and a repressor of transcription

The RGT1 gene of Saccharomyces cerevisiae plays a central role in the glucose-induced expression of hexose transporter (HXT) genes. Genetic evidence suggests that it encodes a repressor of the HXT genes whose function is inhibited by glucose. Here, we report the isolation of RGT1 and demonstrate that it encodes a bifunctional transcription factor. Rgt1p displays three different transcriptional modes in response to glucose: (i) in the absence of glucose, it functions as a transcriptional repressor; (ii) high concentrations of glucose cause it to function as a transcriptional activator; and (iii) in cells growing on low levels of glucose, Rgt1p has a neutral role, neither repressing nor activating transcription. Glucose alters Rgt1p function through a pathway that includes two glucose sensors, Snf3p and Rgt2p, and Grr1p. The glucose transporter Snf3p, which appears to be a low-glucose sensor, is required for inhibition of Rgt1p repressor function by low levels of glucose. Rgt2p, a glucose transporter that functions as a high-glucose sensor, is required for conversion of Rgt1p into an activator by high levels of glucose. Grr1p, a component of the glucose signaling pathway, is required both for inactivation of Rgt1p repressor function by low levels of glucose and for conversion of Rgt1p into an activator at high levels of glucose. Thus, signals generated by two different glucose sensors act through Grr1p to determine Rgt1p function.
Identification of dominant modes in the interface between two conducting fluids

There are several applications in magnetic fluid dynamics where it is important to know the behavior of separation surfaces between fluids. Our magnetic field tomography system enables to reconstruct interface shapes between two conducting fluids on the basis of magnetic field measurements. A simple direct searching strategy for an identification of dominant modes of the interface in a cylindrical two-fluid system is presented
