Dynamics of Thin Film Under a Volatile Solvent Source Driven by a Constant Pressure Gradient Flow

The evolution of a thin liquid film subject to a volatile solvent source and an air-blow effect which modifies locally the surface tension and leads to Marangoni-induced flow is shown to be governed by a degenerate fourth order nonlinear parabolic h-evolution equation of the type given by ∂ t h = − div x M 1 h ∂ x 3 h + M 2 h ∂ x h + M 3 h , where the mobility terms M 1 h and M 2 h result from the presence of the source and M 3 h results from the air-blow effect. Various authors assume M 2 h ≈ 0 and exclude the air-blow effect into M 3 h . In this paper, the authors show that such assumption is not necessarily correct, and the inclusion of such effect does disturb the dynamics of the thin film. These emphasize the importance of the full definition t → · grad γ = grad x γ + ∂ x h grad y γ of the surface tension gradient at the free surface in contrast to the truncated expression t → · grad γ ≈ grad x γ employed by those authors and the effect of the air-blow flowing over the surface.
Activeness and Loyalty Analysis in Event-Based Social Networks

Event-based social networks (EBSNs) are widely used to create online social groups and organize offline events for users. Activeness and loyalty are crucial characteristics of these online social groups in terms of determining the growth or inactiveness of the social groups in a specific time frame. However, there is less research on these concepts to clarify the existence of groups in event-based social networks. In this paper, we study the problem of group activeness and user loyalty to provide a novel insight into online social networks. First, we analyze the structure of EBSNs and generate features from the crawled datasets. Second, we define the concepts of group activeness and user loyalty based on a series of time windows, and propose a method to measure the group activeness. In this proposed method, we first compute a ratio of a number of events between two consecutive time windows. We then develop an association matrix to assign the activeness label for each group after several consecutive time windows. Similarly, we measure the user loyalty in terms of attended events gathered in time windows and treat loyalty as a contributive feature of the group activeness. Finally, three well-known machine learning techniques are used to verify the activeness label and to generate features for each group. As a consequence, we also find a small group of features that are highly correlated and result in higher accuracy as compared to the whole features.
The Impact of a Holistic Intervention on Self-Efficacy and Risk of Depression in HIV-Infected Individuals in Denmark

Introduction: Human immunodeficiency virus (HIV) infection is a stressful disease, and depression is frequently experienced by HIV-infected individuals. The aim of this pilot study was to investigate whether a holistic intervention could improve coping self-efficacy strategies and have a positive impact on the mental health of HIV-infected individuals 12 months posterior to the intervention.
Fault Detection in a Multistage Gearbox Based on a Hybrid Demodulation Method Using Modulation Intensity Distribution and Variational Mode Decomposition

It is critical to detect hidden, periodically impulsive signatures caused by tooth defects in a gearbox. A hybrid demodulation method for detecting tooth defects has been developed in this work based on the variational mode decomposition algorithm combined with modulation intensity distribution. An original multi-component signal is first non-recursively decomposed into a number of band-limited mono-components with specific sparsity properties in the spectral domain using variational mode decomposition. The hidden meaningful cyclostationary features can be clearly identified in the bi-frequency domain via the modulation intensity distribution (MID) technique. Moreover, the reduced frequency aliasing effect of variational mode decomposition is evaluated as well, which is very useful for separating noise and harmonic components in the original signal. The influences of the spectral coherence density and the spectral correlation density of the modulation intensity distribution on the demodulation were also investigated. The effectiveness and noise robustness of the proposed method have been well-verified using a simulated signal compared with the empirical mode decomposition algorithm associated with modulation intensity distribution. The proposed technique is then applied to detect four different defects in a multi-stage gearbox. The results demonstrated that the demodulated numerical information and pigmentation directly illustrated in the bi-frequency plot of the modulation intensity distribution can be successfully used to quantitatively differentiate the four gear defects.
Efficacy of Feeding of Morinda citrifolia Fruit Juice and Lactobacillus acidophilus in Broiler

An experiment was conducted to study the efficacy of feeding of Morinda citrifolia fruit juice (noni) and Lactobacillus acidophilus (LAB) and their combination in commercial broilers. Commercial broiler chicks were fed till 7 weeks of age as per Bureau of Indian Standards (BIS). At day old age, chicks were randomly assigned to each of four water supplement treatments namely, T1 (5 mL noni juice/bird/day), T2 {5 mL (1×10 CFU mLG) LAB/bird/day}, T3 (2.5 mL noni+2.5 mL LAB/bird/day) and T4 (control with basal diet only). The birds were maintained under deep litter system of rearing and provided with normal basal ration throughout the experiment period. Results revealed that broilers given with noni juice recorded significantly (p<0.05) higher mean body weight (451.9±17.1 and 1434.5±60.5 g) and weight gain (402.5±18.4 and 1391±60.3 g) at 21 and 49 days, respectively. Control group recorded significantly comparable body weight and weight gain. Feed efficiency was significantly (p<0.05) better (1.6 ±0.17) in noni group. Humoral immune response in noni+LAB group (0.73) was found to be significantly higher than control group (0.36) and other treatment groups (0.53) at one week post inoculation of Goat Red Blood Cells (GRBC). Noni and LAB groups showed significant (p<0.05) reduction in the coliform load. Treatment groups did not influence pH of intestine and carcass yield significantly. The feed consumption of the noni group was 10% lower than the other groups thus in turn it saved the feed cost of 5.39 per bird. Based on the present study, it is concluded that the feeding of Morinda citrifolia juice showed improved growth performance, high immune response, low gut microbial load and feed cost efficiency in commercial broilers and the combination of noni and LAB might be promising alternatives for antibiotic growth promoters to improve the production of safety poultry products.
Dynamic Force Production Capacities Between Coronary Artery Disease Patients vs. Healthy Participants on a Cycle Ergometer

Background The force-velocity-power (FVP) profile is used to describe dynamic force production capacities, which is of great interest in training high performance athletes. However, FVP may serve a new additional tool for cardiac rehabilitation (CR) of coronary artery disease (CAD) patients. The aim of this study was to compare the FVP profile between two populations: CAD patients vs. healthy participants (HP). Methods Twenty-four CAD patients (55.8 ± 7.1 y) and 24 HP (52.4 ± 14.8 y) performed two sprints of 8 s on a Monark cycle ergometer with a resistance corresponding to 0.4 N/kg × body mass for men and 0.3 N/kg × body mass for women. The theoretical maximal force (F0) and velocity (V0), the slope of the force-velocity relationship (Sfv) and the maximal mechanical power output (Pmax) were determined. Results The Pmax (CAD: 6.86 ± 2.26 W.kg–1 vs. HP: 9.78 ± 4.08 W.kg–1, p = 0.003), V0 (CAD: 5.10 ± 0.82 m.s–1 vs. HP: 5.79 ± 0.97 m.s–1, p = 0.010), and F0 (CAD: 1.35 ± 0.38 N.kg–1 vs. HP: 1.65 ± 0.51 N.kg–1, p = 0.039) were significantly higher in HP than in CAD. No significant difference appeared in Sfv (CAD: −0.27 ± 0.07 N.kg–1.m.s–1 vs. HS: −0.28 ± 0.07 N.kg–1.m.s–1, p = 0.541). Conclusion The lower maximal power in CAD patients was related to both a lower V0 and F0. Physical inactivity, sedentary time and high cardiovascular disease (CVD) risk may explain this difference of force production at both high and low velocities between the two groups.
Fingerprinting of falsified artemisinin combination therapies via direct analysis in real time coupled to a compact single quadrupole mass spectrometer

Falsified anti-malarial treatments continue to constitute a major health crisis, especially in malarious Africa. Even after detection of poor quality pharmaceuticals, it is critical that they be fully analyzed to determine their components, in order to assess their health effects and ultimately allow forensic tracing of their sources of production and distribution. Timely assessment requires robust and complete field-testing, or at the very least timely analysis after seizure or purchase. Ideally, low-cost and simple analytical equipment such as portable mass spectrometry (MS) is the best approach for achieving this quick and informative analysis. To date, Direct Analysis in Real Time (DART) MS has been successfully implemented to rapidly analyze falsified artemisinin-based combination therapies (ACTs) in laboratory settings, but this approach typically translates into high-cost and the need for high-resolution instrumentation. Here, we examine the use of DART ionization coupled with a portable low-resolution single-quadrupole instrument, and compare its success in fingerprinting anti-malarial tablets with higher resolution instrumentation. Using single quadrupole DART-MS, the same sample components were detected as with the high-resolution instrument, while needing significantly less consumables and power, and the additional advantages of increased portability and ease of use. Using Principal Component Analysis (PCA) of DART data, specific classes of falsified ACTs were identified, providing a more straightforward method for sourcing counterfeits and assessing their similarities.
A novel approach to understand nested layers in quality improvement

Studies on healthcare quality improvement (QI) increasingly point at the importance of understanding multilevel organizational issues, especially interaction between national, hospital and clinical level. In a EU-study involving ten hospitals in five countries one hospital stood out in successful multilevel QI work, which is elaborated in this paper. It is suggested that there is a potential in using linkages and dependencies in terms of organisational development and resource support (O) and method, process and IT support (T) affecting the individual caregiver (H), to understand the nestedness and interaction between operational system levels in QI.
Recognition of Negative Emotion Using Long Short-Term Memory with Bio-Signal Feature Compression

Negative emotion is one reason why stress causes negative feedback. Therefore, many studies are being done to recognize negative emotions. However, emotion is difficult to classify because it is subjective and difficult to quantify. Moreover, emotion changes over time and is affected by mood. Therefore, we measured electrocardiogram (ECG), skin temperature (ST), and galvanic skin response (GSR) to detect objective indicators. We also compressed the features associated with emotion using a stacked auto-encoder (SAE). Finally, the compressed features and time information were used in training through long short-term memory (LSTM). As a result, the proposed LSTM used with the feature compression model showed the highest accuracy (99.4%) for recognizing negative emotions. The results of the suggested model were 11.3% higher than with a neural network (NN) and 5.6% higher than with SAE.
mSphere of Influence: Expanding the CRISPR Sphere with Single-Locus Proteomics

Lucy Glover’s research focuses on the role of DNA repair and recombination in antigenic variation in the parasite Trypanosoma brucei, the causative agent of both human and animal African trypanosomiasis. In this mSphere of Influence article, she reflects on how “A CRISPR-based approach for proteomic analysis of a single genomic locus” by Z. J. Waldrip, S. D. Byrum, A. J. Storey, J. ABSTRACT Lucy Glover’s research focuses on the role of DNA repair and recombination in antigenic variation in the parasite Trypanosoma brucei, the causative agent of both human and animal African trypanosomiasis. In this mSphere of Influence article, she reflects on how “A CRISPR-based approach for proteomic analysis of a single genomic locus” by Z. J. Waldrip, S. D. Byrum, A. J. Storey, J. Gao, et al. (Epigenetics 9:1207–1211, 2014, https://doi.org/10.4161/epi.29919) made an impact on her research by taking the precision of CRISPR-Cas9 and repurposing it to look at single-locus proteomics. By using this technology in trypanosomes, Dr. Glover and her colleagues could study the dynamic accumulation of repair proteins after specific damage and gain insight into how the location of a double-strand break (DSB) dictates repair pathway choice and how this may influence immune evasion in these parasites.
An Investigation of Genetic and Environmental Influences Across the Distribution of Self-Control

Previous research illustrating a robust, negative association between self-control and various forms of delinquent and criminal behavior has resulted in a more concentrated focus on the etiological development of self-control. The current study aims to contribute to this literature using a sample of twin and sibling pairs from the National Longitudinal Study of Adolescent to Adult Health (Add Health) to examine genetic and shared environmental influences across levels of self-control. The results of modified DeFries–Fulker (DF) equations revealed that genetic and shared environmental influences were distributed in a nonlinear pattern across levels of self-control. Subsequent biometric quantile regression models revealed that genetic influences on self-control were maximized in the 50th and 60th percentiles, and minimized in the tails of the distribution. Shared environmental influences were nonsignificant at all examined quantiles of self-control with only one exception. The theoretical importance of utilizing genetically informed modeling strategies is discussed in more detail.
A new look at energy harvesting half-duplex DF power splitting protocol relay network over rician channel in case of maximizing capacity

In this paper, the system performance in term of the ergodic capacity of a half-duplex decode-and-forward relaying network over Rician Fading Channel is investigated. The power splitting protocol is proposed for the system model. For this purpose, the analytical mathematical expressions of the ergodic capacity in cases of maximize and no-maximize ergodic capacity are derived and discussed. Furthermore, the effect of various system parameters on the system performance is rigorously studied. Finally, the analytical results are also demonstrated by Monte-Carlo simulation in comparison with the analytical expressions. The research results show that the analytical mathematical and simulated results match for all possible parameter values for both schemes.
Food Science of Animal Resources

Lactobacillus rhamnosus GG (LGG) has low resistance to low pH and bile salt in the gastrointestinal juice. In this study, the gel made from whey protein concentrate (WPC) and pullulan (PUL) was used as the wall material to prepare the microencapsulation for LGG protection. The gelation process was optimized and the properties of gel were also determined. The results showed the optimal gel was made from 10% WPC and 8.0% PUL at pH 7.5, which could get the best protective effect; the viable counts of LGG were 6.61 Log CFU/g after exposure to simulated gastric juice (SGJ) and 9.40 Log CFU/g to simulated intestinal juice (SIJ) for 4 h. Sodium dodecyl sulphite polyacrylamide gel electrophoresis (SDS-PAGE) confirmed that the WPC-PUL gel had low solubility in SGJ, but dissolved well in SIJ, which suggested that the gel can protect LGG under SGJ condition and release probiotics in the SIJ. Moreover, when the gel has highest hardness and water-holding capacity, the viable counts of LGG were not the best, suggesting the relationship between the protection and the properties of the gel was non-linear.
Modeling and designing of variable-period and variable-pole-number undulator

The concept of permanent-magnet variable-period undulator (VPU) was proposed several years ago and has found few implementations so far. The VPUs have some advantages as compared with conventional undulators, e.g., a wider range of radiation wavelength tuning and the option to increase the number of poles for shorter periods. Both these advantages will be realized in the VPU under development now at Budker INP. In this paper, we present the results of 2D and 3D magnetic field simulations and discuss some design features of this VPU.
6 Principles and applications of temporal-focusing wide-field two-photon microscopy

Temporal focusing allows for rapid optically sectioned two-photon widefieldmicroscopy. Depth sectioning is provided in a wide-fieldmanner, without spatial focusing, by controlling the temporal width of femtosecond laser pulses near the focal plane. This spatial control of the temporal pulse width is achieved by diffracting the light off a grating resulting in spectral component separation and temporal broadening; these spectral components are only recombined at the focal plane to reproduce short, femtosecond pulses. Applications include (i) high speed functional imaging in the brain, (ii) fast FLIM and PLIM, (iii) cell-selective optogenetic excitation, and (iv) temporal focusing photodynamic therapy that may allow selective killing of cancer cells.
The CAP Reform Impact on the Italian Durum Wheat Production: an Application of the AG-MEMOD Model

This paper presents the results emerging from the application of alternative Common Agricultural Policy (CAP) scenarios into the Italian econometric country model, developed as part of the AG-MEMOD research project. Major attention is paid on the effect of the 2003 CAP reform on the Italian durum wheat production and a key role in shaping this impact is attributed to national choices. These concern the full or partial decoupling regime for the durum wheat supplementary payment, the introduction of the “quality premium” ex article 69 of the reform and the respective selective application. The implementation of these alternative CAP scenarios within the Italian AG-MEMOD model eventually confirms how critical national choices may be in determining the final outcome of the reform itself.
High‐performance digital logic implementation approach using novel Memristor‐based multiplexer

This paper presents and evaluates novel approaches to design efficient Memristor‐based multiplexers. Three novel algorithms and structures are proposed based on IMP logic operation. These novel algorithms and structures are developed based on Memristors and crossbar Nano wires. The proposed Memristor‐based multiplexers can store the output inside the Memristors. So, the proposed multiplexers have the ability to compute in memory. The proposed multiplexers are simulated using Pspice. The number of required Memristors and necessary steps to accumulate the output for the proposed 2 to 1 multiplexers is reduced in comparison with the former best MUXs. Moreover, these novel multiplexers are utilized to design ISCAS'85 benchmark circuits. The results show improvements in terms of total propagation delay and the required layout area.
Foreword

This article continues issues raised in a book ”New perspectives on transfer and boundary crossing” (Tuomi-Gröhn & Engeström, 2003). The book deals with different conceptualizations on transfer and their applications in school and work situations. While editing this book I noticed that, in addition to the concept of transfer, also the concept of context is used in many different meanings. Discussion between scholars representing different paradigms is sometimes confusing because the same terms are used referring to different things. This is also the case with the concepts of transfer and context. How these concepts are conceptualized is related to the approach of learning. The aim of this article is to present an overview to current approaches to learning, and to the concepts of transfer and context related to them. In addition, a new conceptualization on transfer, based on activity theory, is presented. In order to understand this concept, called developmental transfer, and learning and context concepts related to it, also other current approaches to learning are discussed. In addition to activity theory, cognitive views, phenomenography, and situated views are presented and analyzed here. COGNITIVE APPROACHES Constructivism and cognitive science are very popular among some scholars and scientists of today (Bereiter & Scardamalia, 1985, Gardner, 1987, Anderson et al., 1995, Salomon, 1997) Learning is, in contrast to behavioristic notions, a construction of the knowledge and world. Cognition is the activity of knowing: the acquisition, organization and use of knowledge. In this process, the meaning of mental representations is of primary importance. Gardner (1987, 383) depicts it as follows: The major accomplishment of cognitive science has been the clear demonstration of the validity of positing a level of mental representation: a set of constructs that can be invoked for the explanation of cognitive phenomena, ranging from visual perception to story comprehension. When, at the height of behaviorist era, few scientists dared to speak of schemas, images, rules, transformations, and other mental structures and operations, these representational assumptions and concepts are now taken for granted and permeate the cognitive sciences.
Development of a new propolis microemulsion system for topical applications

Microemulsion systems (MES) offer advantages as drug delivery systems, among them favour drug absorption, being in most case more efficient than other methods in delivering of drug. In this work a new MES was obtained in order to be applied as a pressurized aerosol formulation containing bee propolis ethanolic extract (PEE). For that, pseudoternary phase diagrams were used to characterize the microemulsions boundaries and also to define the Winsor IV microemulsion region of the PEE-MES system containing Tween 80 as surfactant and the cosurfactant ethyl alcohol in small percentage. The obtained results indicated that the best MES was composed by Tween 80 and ethyl alcohol with C/S (cosurfactant/surfactant) ratio equal to 1.0, since it provided a large boundaries in the obtained O/W microemulsion region. This PEE-MES formulation, in which bee propolis consisting as oil phase, is herein designed for topical uses (PEE-MES spraying) in order to treat mouth and throat inflammatory infections. Considering the very large uses of bee propolis in conventional vehicles, MES type of delivery system has to be compatible with achieving the highest drug aim loadings, determined substantially by the specific MES application (drug solubilization in water systems) improving in this case, propolis farmacological aplications. Additionally, PEE-MES antibacterial effect was evidenced and the microemulsion system PEE-MES was also used as newest chemical approach for extraction of bee propolis material from resinous hive.
