Triaryl Pyrazoline Compound Inhibits Flavivirus RNA Replication

ABSTRACT Triaryl pyrazoline {[5-(4-chloro-phenyl)-3-thiophen-2-yl-4,5-dihydro-pyrazol-1-yl]-phenyl-methanone} inhibits flavivirus infection in cell culture. The inhibitor was identified through high-throughput screening of a compound library using a luciferase-expressing West Nile (WN) virus infection assay. The compound inhibited an epidemic strain of WN virus without detectable cytotoxicity (a 50% effective concentration of 28 μM and a compound concentration of ≥300 μM required to reduce 50% cell viability). Besides WN virus, the compound also inhibited other flaviviruses (dengue, yellow fever, and St. Louis encephalitis viruses), an alphavirus (Western equine encephalitis virus), a coronavirus (mouse hepatitis virus), and a rhabdovirus (vesicular stomatitis virus). However, the compound did not suppress an orthomyxovirus (influenza virus) or a retrovirus (human immunodeficiency virus type 1). Mode-of-action analyses in WN virus showed that the compound did not inhibit viral entry or virion assembly but specifically suppressed viral RNA synthesis. To examine the mechanism of inhibition of dengue virus, we developed two replicon systems for dengue type 1 virus: (i) a stable cell line that harbored replicons containing a luciferase reporter and a neomycin phosphotransferase selection marker and (ii) a luciferase-expressing replicon that could differentiate between viral translation and RNA replication. Analyses of the compound in the dengue type 1 virus replicon systems showed that it weakly suppressed viral translation but significantly inhibited viral RNA synthesis. Overall, the results demonstrate that triaryl pyrazoline exerts a broad spectrum of antiflavivirus activity through potent inhibition of viral RNA replication. This novel inhibitor could be developed for potential treatment of flavivirus infection.
Generating colored point cloud under the calibration between TOF and RGB cameras

3D point cloud is the original format of three dimensional map for the navigation of mobile robotics. Time of Flight camera can directly return 3D points and grayscale image simultaneously, but the color information is lost. In this paper, 3D points are colored by calibrating PMD camera with RGB camera, and then the RGB image is generated with respect to a frame of TOF camera. Point cloud form only one frame is not large enough for navigating the robot or observing the environment, an approach for combining two continuous frames is also proposed. Scale invariant features are detected from the RGB images generated, and features from two images are matched accurately. Iterative Closest Point(ICP) algorithm is used to estimate the relative pose transformation of TOF camera, the initial pose is computed from corresponded 3D feature point pairs. The experiments demonstrate the effectiveness of the approach proposed in the paper.
A formulation of the simple theory of types

The purpose of the present paper is to give a formulation of the simple theory of types which incorporates certain features of the calculus of λ-conversion. A complete incorporation of the calculus of λ-conversion into the theory of types is impossible if we require that λx and juxtaposition shall retain their respective meanings as an abstraction operator and as denoting the application of function to argument. But the present partial incorporation has certain advantages from the point of view of type theory and is offered as being of interest on this basis (whatever may be thought of the finally satisfactory character of the theory of types as a foundation for logic and mathematics). For features of the formulation which are not immediately connected with the incorporation of λ-conversion, we are heavily indebted to Whitehead and Russell, Hilbert and Ackermann, Hilbert and Bernays, and to forerunners of these, as the reader familiar with the works in question will recognize. The class of type symbols is described by the rules that ı and o are each type symbols and that if α and β are type symbols then (αβ) is a type symbol: it is the least class of symbols which contains the symbols ı and o and is closed under the operation of forming the symbol (αβ) from the symbols α and β.
Key Beliefs for Targeted Interventions to Increase Physical Activity in Children: Analyzing Data from an Extended Version of the Theory of Planned Behaviour

Given the high prevalence of overweight and low levels of physical activity among children, a better understanding of physical activity behaviour is an important step in intervention planning. This study, based on the theory of planned behaviour, was conducted among 313 fifth graders and their parents. Children completed a computer-based questionnaire to evaluate theoretical constructs and behaviour. Additional information was obtained from parents by means of a questionnaire. Correlates of children's physical activity were intention and self-identity. Determinants of intention were self-efficacy, self-identity, and attitude. Parental variables were mediated through cognitions. Among girls, practicing sedentary activities was an additional negative determinant of intention. Key beliefs of boys and girls were related to time management and difficulties associated with physical activity. For girls, social identification as an active girl was another important belief related to positive intention. This study provides theory-based information for the development of more effective interventions aimed at promoting physical activity among children.
Barriers to Service Provision for Justice-Involved Youth

Despite robust evidence for the efficacy of the Risk-Need-Responsivity (RNR) framework, the needs of youth on community supervision, as identified by risk–need assessments, are frequently not reflected in the services they receive. Potential barriers to recommended service were examined in 219 Canadian youths who were court-ordered to receive forensic assessments. Decreased service was associated with certain criminogenic needs (e.g., antisocial attitudes, substance abuse) that were treatment impeding in nature. Lower treatment receipt was also associated with youth whose parents were detached from the probation process. Furthermore, odds of recidivism increased when youth experienced more lifestyle destabilizers, capacity issues, and systemic barriers, even after accounting for the effect of receiving intervention for identified criminogenic needs. Results suggest the importance of addressing both criminogenic and noncriminogenic factors during probation sentences and call for greater adherence to, and expansion of, the responsivity principle to include the assessment and management of destabilizing and systemic factors.
Phonotactics, density, and entropy in spoken word recognition

Previous research has demonstrated that increases in phonotactic probability facilitate spoken word processing, whereas increased competition among lexical representations is often associated with slower and less accurate recognition. We examined the combined effects of probabilistic phonotactics and lexical competition by generating words and nonwords that varied orthogonally on phonotactics and similarity neighbourhood density. The results from a speeded same-different task revealed simultaneous facilitative effects of phonotactics and inhibitory effects of lexical competition for real word stimuli. However, the nonword stimuli produced an apparently anomalous pattern of results. In a subsequent experiment, we identified the source of this anomaly by estimating behaviourally the specific lexical competitors activated by our nonwords. Our results suggest that, under specific circumstances, neighbourhood density and probabilistic phonotactics may combine to produce non-additive or synergistic effects of lexical competition on processing times.
Speaker Identification With Whispered Speech for the Access Control System

This work presents an access control system, which is a speaker identification system based on whispered speech. Speaker identification is a main function of an access control system. Hence, a novel speaker identification system using instantaneous frequencies is proposed. The input speech signals pass through both signal independent and signal dependent filters firstly. Then, we derive the signal's instantaneous frequencies by applying the Hilbert transform. The analyzed instantaneous frequencies are proceeded to be modeled as probability density models. We use these probability density models as the feature in the proposed speaker identification system. In this work, we compare the use of parametric and nonparametric probability density estimation for instantaneous frequency modeling. Furthermore, we propose an approximated probability product kernel support vector machine (APPKSVM). In the APPKSVM, Riemann sum is applied in approximating the probability product kernel. The whisper sounds from the CHAIN speech corpus were used in the experiments. Results of the experiments show the superiority of the proposed speaker identification system.
Improving family-centered care in Juvenile Justice Institutions

The central focus of this thesis was on developing, implementing and studying Family-centered Care (FC) in short-term stay groups in Juvenile Justice Institutions (JJIs) in the Netherlands. Part of this research project was the bottom-up development of the FC program and the evaluation of its implementation success, for which we used quantitative and qualitative techniques. The overall aim of this thesis was to optimize care for detained youth by contributing to the knowledge, policy, and practice of family-centered care in JJIs. Hence, this study held five sub-aims. First, we aimed to develop a program for family-centered care, including a format for the accompanying training and coaching procedures for JJI staff. Our second aim was to study the effects of FC in practice, using a mixed methods research strategy. The third aim was examining to what extent parents participated in family activities and identifying which factors predicted parental participation. The fourth aim was to understand what parents’ needs are in family-centered care, what they expect from activities, and from JJI staff members. The fifth aim of this thesis was to gain a deeper understanding of which factors parents consider to influence parental participation.
Environmental Risk Information Seeking: The Differential Roles of Anxiety and Hopelessness

ABSTRACT Americans’ concern about water quality has increased over the years. Indeed, several water issues made national news coverage during the past few years, such as lead in Flint, Michigan, algae blooms in Florida, and water quality at the Rio Olympics. In this study, we test two alternate paths of engagement relative to how people respond to water problems. First, we examine anxiety as a key variable that triggers active information seeking behaviors. Second, we look at hopelessness as an intervening variable that could explain why some people become disengaged with issues. Additionally, we test whether response efficacy moderates the relationships between perceiving a problem with water and these emotions. Using survey data collected during the fall of 2015, we examine the role of different emotions in increasing and decreasing active information seeking behaviors.
The impact of alcohol consumption on homicide: A time-series analysis of three Nordic countries

The article explores the statistical association between annual alcohol consumption and homicide mortality in Finland, Sweden and Norway from the early 19th century to 2013. The results show statistically significant impacts on overall and male homicide mortality in Finland and on male homicide mortality in Sweden. In Norway, we found no significant impacts. The results suggest that changes in the level of alcohol consumption have had a stronger impact on homicide rates in Finland, characterized by a heavier drinking culture, than in Norway or Sweden. The strength of the association between alcohol consumption and homicide levels seems also to vary over time and to be conditioned by economic and socio-political factors.
A solar reflectance method for retrieving the optical thickness and droplet size of liquid water clouds over snow and ice surfaces

Cloud optical thickness and droplet effective radius retrievals from solar reflectance measurements are traditionally implemented using a combination of spectral channels that are absorbing and nonabsorbing for water particles. Reflectances in nonabsorbing channels (e.g., 0.67, 0.86, 1.2 μm spectral window bands) are largely dependent on cloud optical thickness, while longer-wavelength absorbing channels (1.6, 2.1, and 3.7 μm window bands) provide cloud particle size information. Cloud retrievals over ice and snow surfaces present serious difficulties. At the shorter wavelengths, ice is bright and highly variable, both characteristics acting to significantly increase cloud retrieval uncertainty. In contrast, reflectances at the longer wavelengths are relatively small and may be comparable to that of dark open water. A modification to the traditional cloud retrieval technique is presented. The new algorithm uses only a combination of absorbing spectral channels for which the snow/ice albedo is relatively small. Using this approach, retrievals have been made with the MODIS airborne simulator (MAS) imager flown aboard the high-altitude NASA ER-2 from May to June 1998 during the Arctic FIRE-ACE field deployment. Data from several coordinated ER-2 and in situ University of Washington Convair-580 aircraft observations of liquid water stratus clouds are examined. MAS retrievals of optical thickness, droplet effective radius, and liquid water path are shown to be in good agreement with in situ measurements. The initial success of the technique has implications for future operational satellite cloud retrieval algorithms in polar and wintertime regions.
Implementation of IMU sensor for elbow movement measurement of Badminton players

This paper gives an insight on the design and development of a mobile measurement device to measure the elbow joint movement of a Badminton player. Badminton is one of the fastest racket-based sport. Since a human eye alone is not capable of capturing all these fast movements the usage of high processing optometric system became a popularity but the downside is these systems are expensive and large in size. The proposed solution is to develop a reasonably cheap and small size mobile measurement device utilizing the miniature sensor technology which can perform the task capturing the badminton player's movements just as an optometric system will do. This proposed device will use the MPU6050 IMU unit to measure the rotational angle of the elbow joint where the data fusion between the accelerometer and gyro will be performed by the inboard MPU6050 DMP. Experiments were conducted to verify the reliability and feasibility of IMU sensor towards the design of this proposed measurement device. The experiments result shows promising results of the usability of the IMU sensor in measuring the rotational angle of the players elbow joint.
Fibrin-mediated Protection Against Infection-stimulated Immunopathology

Fibrin, a product of the blood coagulation cascade, accompanies many type 1 immune responses, including delayed-type hypersensitivity, autoimmunity, and graft rejection. In those settings, fibrin is thought to exacerbate inflammation and disease. Here, we evaluate roles for coagulation during infection with Toxoplasma gondii, a pathogen whose control requires robust type 1 immunity. We establish that fibrin prevents infection-stimulated blood loss, thereby performing a protective function that is essential for survival. Remarkably, fibrin does not simply protect against vascular damage caused directly by the infectious agent, but rather, protects against hemorrhage evoked by interferon-γ, a critical mediator of type 1 immunity. This finding, to our knowledge, is the first to document a beneficial role for coagulation during type 1 immunity, and suggests that fibrin deposition protects host tissue from collateral damage caused by the immune system as it combats infection.
Consecutive Intake of Fermented Milk Containing Bifidobacterium breve Strain Yakult and Galacto-oligosaccharides Benefits Skin Condition in Healthy Adult Women

A double-blind, placebo-controlled, randomized trial was conducted to investigate the beneficial effect of probiotic and prebiotic fermented milk on the skin of healthy adult women. Forty healthy Japanese adult female volunteers with healthy skin randomly received either a bottle of probiotic and prebiotic fermented milk containing Bifidobacterium breve strain Yakult and galacto-oligosaccharides (GOS) (active group) or a non-fermented placebo milk containing neither probiotics nor GOS (placebo group) daily for 4 weeks. Before and after intake, hydration levels and cathepsin L-like activity in the stratum corneum and phenol levels in the serum and urine were determined. After intake, the hydration level of the stratum corneum decreased significantly in only the placebo group and was significantly lower than in the active group (p=0.031). Cathepsin L-like activity, an indicator of keratinocyte differentiation, was significantly increased in the active group (p=0.027). Serum and urine phenol levels decreased significantly in the active group (p=0.014, p=0.002, respectively), and serum phenol levels were significantly lower in the active group compared with the placebo group (p=0.006). The consecutive intake of probiotic and prebiotic fermented milk can benefit skin condition without dryness and decrease the levels of phenol production by gut bacteria in healthy adult women.

Do National and International Media Cover the Same Event Differently? The Online Media Framing of Irreecha Festival Tragedy

ABSTRACT This article examines how media framed the deadly stampede that killed several dozen people gathered to celebrate a festival in Ethiopia. News articles published by 14 national media (N=21) and 116 international media (N=117) on October 2 and 3, 2016 were collected and comparative content analysis was carried out between April and May 2017. Conflict, attribution of responsibility and political consequences frames dominated the coverage. The differences observed in the use of conflict, responsibility and morality frames by national and international media were statistically significant. The differences in the appearance of political consequences and human-interest frames in national and international media were not statistically significant. In terms of coverage pattern, the themes of headlines of almost all the news articles published on the first day after the incident focused on deaths of people whereas the second day headlines diverged to deaths, mourning, unrest that followed, and other issues as the media found additional facts to organise strong and compelling frames to influence the audience. Based on the findings, this article generalises that national and international media cover the same disaster from different perspectives—national media promote national interest whereas international media emphasise conflict.
Neuronal Stability and Drift across Periods of Sleep: Premotor Activity Patterns in a Vocal Control Nucleus of Adult Zebra Finches

How stable are neural activity patterns compared across periods of sleep? We evaluated this question in adult zebra finches, whose premotor neurons in the nucleus robustus arcopallialis (RA) exhibit sequences of bursts during daytime singing that are characterized by precise timing relative to song syllables. Each burst has a highly regulated pattern of spikes. We assessed these spike patterns in singing that occurred before and after periods of sleep. For about half of the neurons, one or more premotor bursts had changed after sleep, an average of 20% of all bursts across all RA neurons. After sleep, modified bursts were characterized by a discrete, albeit modest, loss of spikes with compensatory increases in spike intervals, but not changes in timing relative to the syllable. Changes in burst structure followed both interrupted bouts of sleep (1.5–3 h) and full nights of sleep, implicating sleep and not circadian cycle as mediating these effects. Changes in burst structure were also observed during the day, but far less frequently. In cases where multiple bursts in the sequence changed in a single cell, the sequence position of those bursts tended to cluster together. Bursts that did not show discrete changes in structure also showed changes in spike counts, but not biased toward losses. We hypothesize that changes in burst patterns during sleep represent active sculpting of the RA network, supporting auditory feedback-mediated song maintenance.
Method of Structural Damage Test Based on PSO Algorithm

In this paper, we improved the particle swarm optimization (PSO) algorithm with inertial weight by adopting the sigmoid function. The IPSO is applied to structural damage identification in frame structures. Firstly the theoretical background of the improved PSO (IPSO) algorithm is presented. Secondly, we use a suite of four famous benchmark functions to evaluate the algorithm performance. Some comparative studies on single and multi-damage of a 2-story rigid frame structure have been carried out. The results of the numerical simulation demonstrate that the approach can detect the structural damage with higher accuracy.
