Children’s Television Viewing and ADHD-related Behaviors: Evidence from the Netherlands

This study examined how ADHD-related behaviors are associated with children’s overall amount of television viewing, specific content viewing (i.e. violent/scary and educational), and attention and arousal responses when viewing television. Additionally, it explored the moderating role of children’s sex in these relationships. To address these aims, parents of 865 Dutch children (3–7 years) completed a survey measuring ADHD-related behaviors and kept four-day television diaries. We found that ADHD-related behaviors were not associated with overall viewing nor with violent/scary content viewing. These relationships, however, were moderated by sex. Further analyses of these moderations revealed a positive trend between ADHD-related behaviors and overall and violent/scary content viewing for boys only. ADHD-related behaviors were not related to educational content viewing. Furthermore, ADHD-related behaviors were related to more arousal when viewing television, regardless of content, and less attention to overall and educational television. We did not find sex differences in arousal and attention responses.
Effect of temperature on vibration fatigue of SAC105 solder material after extended room temperature aging

Electronic products are often exposed to combined stress loading conditions (both thermal excursions and vibration) during their service life. In order to assess the performance and durability under these conditions, it is important to use temperature dependent fatigue data to assess or more accurately predict vibration damage under more realistic life-cycle conditions. This paper focuses on finding the temperature dependent vibration durability of aged SAC105 solder material. This is accomplished by using a combination of harmonic vibration tests at different temperatures and nonlinear dynamic FEA. The fatigue durability is found to decrease significantly with increasing temperature, in part due to the increase in solder strain, and in part due to degradation of the solder cyclic fatigue properties. Additionally, the room temperature fatigue results were fitted with the Basquin-Coffin-Manson fatigue model to produce the temperature-dependent model constants for the S-N curves.
A multiscale creep model as basis for simulation of early-age concrete behavior

A previously published multiscale model for early-age cement-based materials [Pichler, et al.2007. "A multiscale micromechanics model for the autogenous-shrinkage deformation of early-age cement-based materials. " Engineering Fracture Mechanics, 74, 34-58] is extended towards upscaling of viscoelastic properties. The obtained model links macroscopic behavior, i.e., creep compliance of concrete samples, to the composition of concrete at finer scales and the (supposedly) intrinsic material properties of distinct phases at these scales. Whereas finer-scale composition (and its history) is accessible through recently developed hydration models for the main clinker phases in ordinary Portland cement (OPC), viscous properties of the creep active constituent at finer scales, i.e., calcium-silicate-hydrates (CSH) are identified from macroscopic creep tests using the proposed multiscale model. The proposed multiscale model is assessed by different concrete creep tests reported in the open literature. Moreover, the model prediction is compared to a commonly used macroscopic creep model, the so-called B3 model.
Using Positioning Priorities for Accurate Anchor-Based Node Location over Wireless Sensor Networks

Accurate node locations are critically demanded for various WSN applications. A widely adopted approach assumes a few nodes used as anchor nodes whose locations are known and the distances between nodes can be estimated. The accuracy of existing estimation can be improved due to the flip ambiguity (FA) phenomena. This paper presents an original anchor-based node location approach for better accuracy by using positioning priorities. We first comprehensively investigate the FA phenomena and study its effect factors, then introduce a new concept exploring the node positioning priority to avoid FA as much as possible. Finally an empirical simulation study has been carried out to evaluate our proposed approach against the simulated annealing based location (SAL), genetic algorithm based location (GAL) and collinearity-aware trilateration incorporated with the implicit collinearity method (TRI-ICD). The experimental results show that our proposed approach reduce location errors.
A Pulse Energy Injection Inverter for the Switch-Mode Inductive Power Transfer System

Considering the coupling relationships between transfer power and efficiency in continuous-mode inductive power transfer (IPT) systems, this paper presents a pulse energy injection inverter for IPT systems. With a new topology and parameters tuning, the pulse energy injection IPT system with the proposed inverter can work in switch-mode to decouple transfer power with efficiency. Moreover, the transfer power is only decided by the duty ratio of the semiconductor switch, rather than affected by the transmitting resonator, receiving (Rx) resonator, and load. In this way, the pulse energy injection IPT system holds an operating frequency much lower than the resonant frequency to reduce switch loss and improve transfer efficiency. Experiments verify that the IPT system with proposed inverter maintains a high level efficiency within the middle range and realizes nearly 80% supply to load transfer efficiency even in a weak coupling coefficient ( $k=0.044$ ). Finally, experimental analysis implies that the pulse energy injection inverter is suitable for full-range transmission, and high-Q IPT systems with uncertainty in Rx circuits or load.
The Impacts of Yield on Nutritional Quality: Lessons from Organic Farming

A majority of well-designed studies comparing nutrient density (milligrams of a given nutrient per kilogram of food) in organically and conventionally produced fruits and vegetables show modest to moderately higher concentrations of most nutrients in organic produce. Likewise, organic produce is either as flavorful as or more flavorful than conventional produce and often tends to store better. Physiological factors that may account for these differences include the levels and form of nitrogen applied to crops, the balance of macro- and micronutrients in the soil, soil quality, average cell size, glycosylation status, and concentrations of plant secondary metabolites. AN EASY QUESTION Our colloquium poses the important ques- tion, ''Crop yield and quality: can we max- imize both? '' For the majority of agronomic crops and ecosystems, the answer is ''no,'' at least if taste and nutrient density are central to one's definition of food quality. By ''nutrient density,'' I mean the concentration of nutrients in a given food, which is typically reported as milligrams of nutrient per kilogram of food and may be measured and reported on a fresh or dry weight basis. Much of the focus of agricultural research over the last few decades has been on pushing yields higher coupled with minimizing or otherwise dealing with the problems that arise when yields are pushed above one of these plateaus or thresholds. Although sci- ence and technology have been remarkably successful in pushing these plateaus higher, it has not eliminated them and likely never will for the vast majority of food. Accordingly, we cannot maximize both yields and crop quality when quality is defined in terms of nutrient density, taste, and food safety.
Chapter 5 Acute Splenic Sequestration Crisis

Acute splenic sequestration crisis (ASSC) is a life-threatening complication associated with sickle cell anemia (SCA) that consists of an acute fall in hemoglobin produced by red blood cell (RBC) sickling within the spleen. It is also one of the leading causes of death in children with SCA. Occlusion of the splenic vascular supply leads to parenchymal ischemia and tissue necrosis. ASSCs are considered an emergency because of their high morbidity and mortality. Untreated patients may die within 1– 2 h due to circulatory failure. Management is supportive, sometimes with blood transfusion and total or partial splenectomy. The aim of this chapter is to bring the up-to-date knowledge of the epidemiology, pathophysiology, diagnosis, and treatment of ASCC. Other important items consid‐ ered are the spleen dysfunction, susceptibility to infections, and its prevention, disease expression, and to address the different managements for improving prognosis.
The evolutionary ecology of C-4 plants

C4 photosynthesis is a physiological syndrome resulting from multiple anatomical and biochemical components, which function together to increase the CO2 concentration around Rubisco and reduce photorespiration. It evolved independently multiple times and C4 plants now dominate many biomes, especially in the tropics and subtropics. The C4 syndrome comes in many flavours, with numerous phenotypic realizations of C4 physiology and diverse ecological strategies. In this work, we analyse the events that happened in a C3 context and enabled C4 physiology in the descendants, those that generated the C4 physiology, and those that happened in a C4 background and opened novel ecological niches. Throughout the manuscript, we evaluate the biochemical and physiological evidence in a phylogenetic context, which demonstrates the importance of contingency in evolutionary trajectories and shows how these constrained the realized phenotype. We then discuss the physiological innovations that allowed C4 plants to escape these constraints for two important dimensions of the ecological niche – growth rates and distribution along climatic gradients. This review shows that a comprehensive understanding of C4 plant ecology can be achieved by accounting for evolutionary processes spread over millions of years, including the ancestral condition, functional convergence via independent evolutionary trajectories, and physiological diversification.

Examining a rapid calculation method of flux linkages for reluctance machines

This paper examines a rapid calculation method (RCM) to determine transient flux linkages depending on both rotor angle and coil currents. It was originally developed for small permanent magnet DC brush motors. In this paper, the RCM is applied to machines with reluctance rotors. After a short summary of the machines' characteristics, the adapted RCM is presented. Initially, the characteristic of the magnetic circuit of the machine is pre-calculated via conventional finite element analysis. Then, the RCM is used to determine the actual flux linkages of the phases at arbitrary operation points. The RCM drastically reduces the overall calculation time for a thorough analysis. Furthermore, it increases flexibility concerning variables such as different operation points, control modes and power supply. For verification, the RCM results are compared to finite element analysis data. At the end, the potential use of the method is presented based on its calculation accuracy.
Next Generation Sequencing Platforms and its Applications in Genomics

DNA sequencing technology is undergoing a revolution with the commercialization of next genera-tion technologies. Over the past eight to ten years massively parallel DNA sequencing platforms have become widely available with reducing the cost of DNA sequencing. Next generation platform (NGS) includes Helicos Heliscope™, Pacific Biosciences SMRT, Ion Torrent, Oxford Nanopore, etc. These plat-forms have the potential to dramatically accelerate biological research, by enabling the comprehensive analysis of genomes, transcriptomes and interactomes to become inexpensive, routine and widespread. Variant discovery by re-sequencing targeted regions of interest or whole genomes, de novo assemblies of prokaryotic and eukaryotic genomes. Cataloguing the transcriptomes of cells, genome-wide profiling of epigenetic marks and chromatin structure is using other seq-based methods and species classification and gene discovery by metagenomics studies.
Modeling Indirect Lightning Strikes for Railway Systems With Lumped Components and Nonlinear Effects

Induced voltages due to lightning strikes along multiconductor transmission line (MTL) systems terminated with different loads at line ends have been widely studied by solving telegraphers' equations using the finite-difference time-domain method. However, MTL systems with lumped series and shunt-connected devices/components along the lines have not attracted much attention. There are methods available for introducing lumped components along MTL systems. In this paper, a method previously developed by the authors will be used to determine induced voltages across transformers connected to the catenary wire and track-circuit relay units along the MTL system representative of a Swedish single-track railway system for the case of indirect lightning strikes. Nonlinearities like soil ionization and insulator flashovers are also considered. It is found that both the nonlinearities and lumped components together dominate the induced-voltage amplitude and wave shapes across devices/components.
Growing Uniform Graphene Disks and Films on Molten Glass for Heating Devices and Cell Culture

The direct growth of uniform graphene disks and their continuous film is achieved by exploiting the molten state of glass. The use of molten glass enables highly uniform nucleation and an enhanced growth rate (tenfold) of graphene, as compared to those scenarios on commonly used insulating solids. The obtained graphene glasses show promising application potentials in daily-life scenarios such as smart heating devices and biocompatible cell-culture mediums.
Learning-assisted beam search for indoor mmWave networks

This paper proposes a learning-assisted beam search scheme for indoor millimeter wave (mmWave) networks with multi-base stations. Recently, directional antennas are often used to achieve the high data rates and compensate the high freespace loss in the mmWave frequency range. However, establishing reliable communication links with narrow beamwidth is a challenging task in indoor moving environments since the sector search space scales with device mobility and base station density. To tackle such an issue, we develop a multi-state Q-learning approach that incorporates the base station selection into the beam selection process. By exploiting the radio environment data from ray tracing simulation, the proposed learning approach can enable fast and reliable beam selection for different indoor environments and mobility patterns. Simulation results show that the proposed scheme outperforms the beam search schemes based on the existing exhaustive search approach and the original Q-learning approach in terms of beam search latency, link outage times, and aggregated throughput.
An Affect-Based Multimodal Video Recommendation System

People watching a video can almost always suppress their speech but they cannot suppress their body language and manage their physiological and behavioral parameters. Affects/emotions, sensory processing, actions/motor behavior and motivation link to the limbic system responsible for instinctive and instantaneous human reactions to their environment or to other people. Limbic reactions are immediate, sure, time-tested and occur among all people. Such reactions are highly spontaneous and reflect the video viewer’s real feelings and desires, rather than deliberately calculated ones. The limbic system also links to emotions, usually conveyed by facial expressions and movements of legs, arms and/or other body parts. All physiological and behavioral parameters require consideration to determine a video viewer’s emotions and wishes. This is the reason an Affect-based multimodal video recommendation system (ARTIST), developed by the authors of the article, is very suitable. The ARTIST was developed and fine-tuned during the course of conducting the TEMPUS project “Reformation of the Curricula on Built Environment in the Eastern Neighbouring Area”. ARTIST can analyze the facial expressions and physiological parameters of a viewer while watching a video. An analysis of a video viewer’s facial expressions and physiological parameters leads to better control over alternative sequences of film clips for a video clips. It can even prompt ending the video, if nothing suitable for the viewer is available in the database. This system can consider a viewer’s emotions (happy, sad, angry, surprised, scared, disgusted and neutral) and choose rational video clips in real time. The analysis of a video viewer’s facial expressions and physiological parameters can indicate possible offers to viewers for video clips they prefer at the moment.
IGBT versus VDMOS switches in DC-to-AC inverters , some basic comparisons

Renewable energy sources invariably require interfaces for power conversion, and new switches based on modern semiconductors may offer converters with improved efficiency. This study investigated properties of two contemporary voltage-controlled power transistors, and their suitability for use in DC-to-AC inverters. Namely Si IGBT and Si VDMOS were considered. These devices were implemented in a Low-Voltage Single-Phase H-Bridge based Inverter (LVSPHBI) and simulated with LTSPICE, with simulations for different levels of power delivered to a linear resistive load while keeping the DC voltage source constant. The efficiency and total harmonic distortion (THD) were used as measures of merit. The study includes frequency dependence of the efficiency and the THD for various technologies. It was found that each of the transistors has advantages from proper point of view.
hitosan-based thin active layer membrane for forward osmosis esalination

A novel hydrophilic chitosan-based thin active layer membrane was elaborately fabricated through a facile method and its performance was studied in forward osmosis (FO) desalination process. Chitosan (CS) was interfacially polymerized with trimesoyl chloride (TMC) monomer on the surface of sulfonated polyethersulfone-polyethersulfone (SPES-PES) support layer. Two different procedures were employed to incorporate CS into the membrane thin active layer structure. The solutions containing different CS concentrations (from 0.5 to 2.0 wt.%) were firstly loaded on the support layer surface, treated in the presence
SAPA: Self-Aware Polymorphic Architecture

In this work, we introduce a Self-Aware Polymorphic Architecture (SAPA) design approach to support emerging context-aware applications and mitigate the programming challenges caused by the ever-increasing complexity and heterogeneity of high performance computing systems. Through the SAPA design, we examined the salient software-hardware features of adaptive computing systems that allow for (1) the dynamic allocation of computing resources depending on program needs (e.g., the amount of parallelism in the program) and (2) automatic approximation to meet program and system goals (e.g., execution time budget, power constraints and computation resiliency) without the programming complexity of current multicore and many-core systems. The proposed adaptive computer architecture framework applies machine learning algorithms and control theory techniques to the application execution based on information collected about the system runtime performance trade-offs. It has heterogeneous reconfigurable cores with fast hardware-level migration capability, self-organizing memory structures and hierarchies, an adaptive application-aware network-on-chip, and a built-in hardware layer for dynamic, autonomous resource management. Our prototyped architecture performs extremely well on a large pool of applications.
MIMO dongle antennas for LTE700 applications

A design of compact MIMO antenna achieving the band of LTE 700 for fourth generation (4G) technology is proposed and studied. A very compact meandered monopole using the spaces on the front side and back side of the substrate is adopted for the design. The overall size of the design is 60 × 35 × 0.8 mm3, and the antenna portion of the antenna is 20 × 35 × 0.8 mm3, implemented on the FR4 substrate with a relative permittivity of 4.4. The antenna portion is composed of identical two compact meandered monopole antennas to achieve the design goal. The isolation element with M-shaped strip extended from the system ground plane and a small rectangular slot is placed between two antennas to eliminate the induced current between them. The isolation mechanism is produced good isolation. From the experimental results, the antenna achieves the isolation performance and the required bandwidth for LTE 700. Further discussion will be included in the paper.
FEASIBILITY ANALYSIS OF THE MODIFIED POINT MASS TRAJECTORY MODEL FOR THE NEED OF GROUND ARTILLERY FIRE CONTROL SYSTEMS

The work shows computational results of the effect of a simplified mathematical model of the flight dynamics of a spin-stabilized projectile on the accuracy and speed of calculation parameters for the projectile trajectory (in the entire range of operating quadrant elevation of the barrel and possible perturbations of the conditions firing) to determine an appropriate mathematical model for the automated fire control systems of ground artillery.
Effects of Sweet Potato Feathery Mottle Virus and Sweet Potato Chlorotic Stunt Virus on the Yield of SweetPotato in Uganda

Sweet potato feathery mottle virus (SPFMV) and Sweet potato chlorotic stunt virus (SPCSV) are the most common viruses infecting sweetpotato in Uganda. Field plots planted with graft inoculated plants of virus-free cultivars Beauregard, Dimbuka, Ejumula, Kabode and NASPOT 1 were used to assess the effect of SPFMV and SPCSV on yield and quality of sweetpotatoes in two agro-ecologies. SPFMV spreads rapidly to control plots at Makerere University Agricultural Research Institute Kabanyolo (MUARIK), and these plots had similar yields to those singly infected with SPFMV but at the National Semi Arid Resource Research Institute (NaSARRI) where SPFMV spreads slowly, plots infected with SPFMV yielded 40% less than the control. Recovery from SPFMV appeared to be more frequent at NaSARRI than at MUARIK. Infection by SPCSV alone resulted in yield losses of 14–52%, while mixed infections of SPFMV+SPCSV resulted in yield losses in both locations of 60–95% depending on the cultivar. SPCSV and mixed infections of SPFMV+SPCSV also reduced the number of roots formed as well as the diameter of the roots, resulting in a greater length to diameter ratio compared to the healthy control. This study, therefore, confirms that both SPFMV and SPCSV, both singly and when mixed, can reduce yield, the extent depending on the cultivar. To mitigate the effect of these viruses, farmers should use clean planting materials of resistant varieties.
