Manipulation of p-/n-Type Thermoelectric Thin Films through a Layer-by-Layer Assembled Carbonaceous Multilayer Structure

Recently, with the miniaturization of electronic devices, problems with regard to the size and capacity of batteries have arisen. Energy harvesting is receiving significant attention to solve these problems. In particular, the thermoelectric generator (TEG) is being studied for its ability to harvest waste heat energy. However, studies on organic TEGs conducted thus far have mostly used conductive polymers, making the application range of TEGs relatively narrow. In this study, we fabricated organic TEGs using carbonaceous nanomaterials (i.e., graphene nanoplatelet (GNP) and single-walled carbon nanotube (SWNT)) with polyelectrolytes (i.e., poly(vinyl alcohol) (PVA) and poly (diallyldimethyl ammonium chloride) (PDDA)) via layer-by-layer (LbL) coating on polymeric substrates. The thermoelectric performance of the carbonaceous multilayer structure was measured, and it was confirmed that the thermoelectric performance of the TEG in this study was not significantly different from that of the existing organic TEG fabricated using the conductive polymers. The 10 bilayer SWNT thin films with polyelectrolyte exhibited a thermopower of −14 μV·K−1 and a power factor of 25 μW·m−1K−2. Moreover, by simply changing the electrolyte, p- or n-type TEGs could be easily fabricated with carbonaceous nanomaterials via the LbL process. Also, by just changing the electrolyte, p- or n-type of TEGs could be easily fabricated with carbonaceous nanomaterials with a layer-by-layer process.
Set-in-stone

Large-scale binder jetting provides a promising alternative to manual sculpting of sandstone. The weak build material, however, severely limits its use in architectural ornamentation. We propose a structural optimization that jointly optimizes an ornament's strength-to-weight ratio and balance under self-weight, thermal, wind, and live loads. To account for the difference in the tensile and compressive strength of the build material, we turn the Bresler-Pister criterion into a failure potential, measuring the distance to failure. Integrated into an XFEM-based level set formulation, we minimize this potential by changing the topology and shape of the internal structure. To deal with uncertainties in the location of live loads, and the direction of wind loads, we first estimate loads that lead to the weakest structure, then minimize the potential of failure under identified worst-case loads. With the help of first-order optimality constraints, we unify our worst-case load estimation and structural optimization into a continuous optimization. We demonstrate applications in art, furniture design, and architectural ornamentation with three large-scale 3D printed examples.
Use of Cellulose Nanofibers as an Electrode Binder for Lithium Ion Battery Screen Printing on a Paper Separator

Water-based inks were formulated using cellulose nanofibers as a binder in order to directly front/reverse print lithium ion cells on a paper separator. Moreover, the high cohesion of electrodes as provided by cellulose nanofibers allowed for the embedding metallic current collectors in the electrodes during the printing stage, in order to develop a one-step printing and assembling process. Positive and negative inks based on LiFePO4, or graphite, respectively, and cellulose nanofibers, displayed rheological properties complying with a variety of printing processes, as well as with screen printing. Printed cells exhibited high electrical conductivity and adhesion between current collectors and inks, i.e., up to 64 ± 1 J/m2. Electrochemical cycling tests at C/10 showed a reversible capacity during the first cycle of about 80 mAh/g, which slightly decayed upon cycling. Preliminary results and assembling strategies can be considered as promising, and they represent a quick solution for the manufacturing of lithium ion batteries. Work is in progress to improve these processing issues and the cycling performances of Li-ion cells.
Applicability of Diffuse Ultrasound to Evaluation of the Water Permeability and Chloride Ion Penetrability of Cracked Concrete

This study aims to explore the applicability of diffuse ultrasound to the evaluation of water permeability and chloride ion penetrability of cracked concrete. Lab-scale experiments were conducted on disk-shaped concrete specimens, each having a different width of a penetrating crack that was generated by splitting tension along the centerline. The average crack width of each specimen was determined using an image binarization technique. The diffuse ultrasound test employed signals in the frequency range of 200 to 440 kHz. The water flow rate was measured using a constant water-head permeability method, and the chloride diffusion coefficient was determined using a modified steady-state migration method. Then, the effects of crack width on the diffusion characteristics of ultrasound (i.e., diffusivity, dissipation), water flow rate, and chloride diffusion coefficient are investigated. The correlations between the water flow rate and diffuse ultrasound parameters, and between the chloride diffusion coefficient and diffuse ultrasound parameters, are examined. The results suggest that diffuse ultrasound is a promising method for assessing the water permeability and chloride ion penetrability of cracked concrete.
Applications of Gold Nanoparticles in Non-Optical Biosensors

Due to their unique properties, such as good biocompatibility, excellent conductivity, effective catalysis, high density, and high surface-to-volume ratio, gold nanoparticles (AuNPs) are widely used in the field of bioassay. Mainly, AuNPs used in optical biosensors have been described in some reviews. In this review, we highlight recent advances in AuNP-based non-optical bioassays, including piezoelectric biosensor, electrochemical biosensor, and inductively coupled plasma mass spectrometry (ICP-MS) bio-detection. Some representative examples are presented to illustrate the effect of AuNPs in non-optical bioassay and the mechanisms of AuNPs in improving detection performances are described. Finally, the review summarizes the future prospects of AuNPs in non-optical biosensors.

Monitoramento da carga de treinamento: a percepção subjetiva do esforço da sessão é um método confiável? - doi: 10.4025/reveducfis.v21i1.6713

The fundamental goal for a sports coach is to maximize athletic performance. The best performance gains come from prescribing an optimal amount of training loads with appropriate recovery periods to allow a greatest adaptation before competition. Training load is influenced by both training volume and training intensity. A precise understanding of loads performed during training can be beneficial for both the coach and the athlete. The coach can use feedback from training to systematically modify training periodization so that future performances can be improved. Training load can be monitored in many different ways, however, a very simple method was recently proposed by Carl Foster: the session-RPE method. Training monitoring ensures that both sufficient training loads are implemented and that excessive loads are not, leading the coach to better understanding of the training process. Ultimately, this may lead to improved performance in competition. Therefore, there is a great interest in valid and reliable methods for training load monitoring. In this review, we investigated the scientific merit of the Foster´s Session-RPE method. Based on the available data, it seems that the session-RPE method is a useful tool for quantifying training load because it is simple to use, easy to understand and relatively easy to implement. However, additional data is required to validate the Session-RPE method in different sports in an ecological perspective.
Visual Text Entry based on Morse code Generated with Tongue Gestures

〈Summary〉 We propose a vision-based Human-Computer Interface for Text Entry. The system uses a web camera for detecting tongue protrusion gestures, which are interpreted as the signals of International Morse Code. These gestures can be generated independently; hence, the traditional 3:1 ratio between dashes and dots can be disregarded. Employing Morse code for text entry requires memorizing it in advance. In this paper, users are provided with a Visual Chart where input characters are displayed on the screen. Navigating the chart in order to select a character matches perceptually the position of the tongue gestures. Thus, without previous knowledge of Morse code, users are able to start typing just by looking at the screen. Furthermore, the proposed interface allows learning the code by associating it with the tongue actions, while already obtaining tangible results. The Text Entry protocol consists of Timers that can be adjusted according to the level of expertise of users. The best text entry rate obtained was 2.54 WPM. We also provide a method to calculate theoretical speeds, which indicate the lower bound for the speeds obtained in practice. Finally, the Visual Chart contains 30 characters; however, it is possible to expand it in order to encode more information while maintaining the same text entry protocol.
Foundations for the representation of diversity, evolution, opinion and bias

One of the aims of the LivingKnowledge project is to bring a new quality into search and knowledge management technology, by making opinions, bias, diversity and evolution more tangible and more digestible. In order to capture diversity in knowledge, we believe that developing more powerful tools for extracting information from both text and non-text media are keys to the success of the project.
Discovery of a Natural Syk Inhibitor from Chinese Medicine through a Docking-Based Virtual Screening and Biological Assay Study

Spleen tyrosine kinase (Syk) is a critical target protein for treating immunoreceptor signalling-mediated allergies. In this study, a virtual screening of an in-house Chinese medicine database followed by biological assays was carried out to identify novel Syk inhibitors. A molecular docking method was employed to screen for compounds with potential Syk inhibitory activity. Then, an in vitro kinase inhibition assay was performed to verify the Syk inhibitory activity of the virtual screening hits. Subsequently, a β-hexosaminidase release assay was conducted to evaluate the anti-mast cell degranulation activity of the active compounds. Finally, tanshinone I was confirmed as a Syk inhibitor (IC50 = 1.64 μM) and exhibited anti-mast cell degranulation activity in vitro (IC50 = 2.76 μM). Docking studies showed that Pro455, Gln462, Leu377, and Lys458 were key amino acid residues for Syk inhibitory activity. This study demonstrated that tanshinone I is a Syk inhibitor with mast cell degranulation inhibitory activity. Tanshinone I may be a potential lead compound for developing effective and safe Syk-inhibiting drugs.
Iconographic Displays For Visualizing Multidimensional Data

Steeply increasing amounts and complexity of scientific data demand improved capability to display data graphically. A powerful new graphic technique for displaying multidimensional data is explained and illustrated. The basic approach is to represent each datum by a graphic icon, the visible features of which are under control of the multiple measures on each datum. W n the icons are displayed en masse, densely stacked into a two-dimensional array, statistical structure in the data is perceived in the form of texture contours or gradients of texture variation over the display. This approach is illustrated with weather satellite imagery data. Five channels of multispectral data are combined into one picture, in which each pixel is an icon. We also describe how large statistical data bases like medical epidemiological data or census data might be visualized iconographically.
A framework for network traffic analysis using GPUs

During the last years the computer networks have become an important part of our society. Networks have kept growing in size and complexity, making more complex its management and traffic monitoring and analysis processes, due to the huge amount of data and calculations involved. In the last decade, several researchers found effective to use graphics processing units (GPUs) rather than a traditional processors (CPU) to boost the execution of some algorithms not related to graphics (GPGPU). In 2006 the GPU chip manufacturer NVIDIA launched CUDA, a library that allows software developers to use their GPUs to perform general purpose algorithm calculations, using the C programming language. This thesis presents a framework which tries to simplify the task of programming network traffic analysis with CUDA to software developers. The objectives of the framework have been abstracting the task of obtaining network packets, simplify the task of creating network analysis programs using CUDA and offering an easy way to reuse the analysis code. Several network traffic analysis have also been developed.
Investigating Social Dominance in a Prison Population

This study using a prison sample to explore Social Dominance Orientation (SDO), socially dominant inmate behaviour, index offence, age and length of time served in secure environments. A sample of 397 adult male prisoners completed the Direct and Indirect Prisoner Behaviour Checklist‐ Scaled (prisoner behaviour towards other inmates and staff) and the Social Dominance Orientation (SDO) Scale. It was predicted that prisoners would report higher SDO than non‐incarcerated populations and that among inmates those with approach orientated index offences would be higher in SDO than those whose offenses were more remote. It was also predicted that SDO would be related to younger age, higher lifetime rates of incarceration, more negative behaviour towards other inmates and staff, and more resource focused behaviour. The results broadly supported predictions, and possible implications for practice and directions for future research are discussed.
Expectations of successful female small school principals

This paper forms part of a larger study investigating the experiences of twelve female teaching principals in small rural and isolated schools in their first year as school principal. The schools to which they were appointed had student enrolments ranging from 12 to 86 and were in geographic areas with no township, where the school building was the only structure, to small towns of less than 500. This study sought to discover the expectations stakeholders in small schools had of successful female teaching principals and the expectations teaching principals had of themselves. Interviews with both cohorts indicated a shared expectation that the teaching principal would come equipped with excellent communication skills, sound teaching knowledge and the ability to establish and maintain community relationships. Additional expectations from teaching principals related to their leaders hip, meeting systemic administrative requirements and balancing their work and personal lives. For stakeholders additional expectations included being organised in relation to isolation and having positive personal characteristics.
EDUTELLA: P2P Networking for the Semantic Web

Metadata for the World Wide Web is important, but metadata for Peer-to-Peer (P2P) networks is absolutely crucial. In this paper we discuss the open source project Edutella which builds upon metadata standards defined for the WWW and aims to provide an RDF-based metadata infrastructure for P2P applications. Edutella is the first system which brings together RDF and P2P concepts and exploits their strengths in a common framework, suitable for building general schema-based P2P networks for distributed and dynamic information providers. We describe the goals and main services this infrastructure will provide and the architecture to connect Edutella Peers based on exchange of RDF metadata. As the query service is one of the core services of Edutella, upon which other services are built, we specify in detail the Edutella Common Data Model (ECDM) as basis for the Edutella query exchange language (RDF-QEL-i) and format implementing distributed queries over the Edutella network. Finally, we shortly discuss registration and mediation services, and introduce the prototype and application scenario for our current Edutella aware peers.

Adaptive Leader-Following Consensus for Multiple Euler–Lagrange Systems With an Uncertain Leader System

In this paper, we study the leader-following consensus problem of multiple Euler–Lagrange (EL) systems subject to an uncertain leader system. We first establish an adaptive distributed observer for a neutrally stable linear leader system whose system matrix is not known exactly. Under standard assumptions, this adaptive distributed observer can estimate and pass the leader’s state to each follower through the communication network of the system without knowing the leader’s system matrix exactly. Under the additional assumption that the leader’s state is persistently exciting, this adaptive distributed observer can also asymptotically learn the parameters of the leader’s system matrix. On the basis of this adaptive distributed observer, we further synthesize an adaptive distributed control law to solve our problem via the certainty equivalence principle. Our result allows the leader-following consensus problem of multiple EL systems to be solved even if none of the followers knows the system matrix of the leader system exactly.
The Role of Domestic Demand in the Economic Growth of Cote d’Ivoire

Abstract—This study examines the relationship between domestic demand and economic growth in Cote d’Ivoire using time-series data over the period from 1970 to 2015. The study uses two measures for domestic demand, namely household consumption and government consumption. The results show that household consumption and government consumption influence positively economic growth in the short and long-run. These findings suggest that domestic demand can be used as the catalyst for economic growth in Cote d’Ivoire.
Suicide attempts in eating disorder subtypes: a meta-analysis of the literature employing DSM-IV, DSM-5, or ICD-10 diagnostic criteria

Abstract Background Quantification of suicidal risk in specific populations is important for the adoption of targeted prevention and harm reduction measures. Though there remains little systematic evidence, risk of suicide attempts for bulimia nervosa (BN) and binge-purging anorexia nervosa (AN-bp) appears higher than restrictive AN (AN-r); risk in binge eating disorder (BED) is still unclear. The aim of this meta-analysis was to compare proportions of suicide attempts in eating disorder (ED) subgroups. Methods A literature search using combinations of key-words for ED and suicide attempts was performed. Studies reporting proportions of suicide attempters in at least two ED groups, diagnosed according to DSM-IV or -5 and ICD-10 diagnostic criteria were considered. ED subgroups were analyzed in pairs using a binary random effect model for proportions. Publication bias, meta-regression, and sensitivity analyses were performed. Results In BN, attempted suicide was more frequent (21%) than in AN (12.5%), but the difference was statistically significant only when BN was compared with AN-r (9–10%). In BED, the proportion of suicide attempts was as high as in AN (10–12%). Conclusions Though limited by heterogeneity across the studies in terms of methodology and aims, inability to control for relevant confounding variables, exclusion of ED not otherwise specified, this study supports suicide attempts as a major issue in EDs, especially in binge-purging subtypes, i.e. BN and AN-bp. Similar suicidal proportions were observed in AN and BED. The reasons for a greater proportion of attempted suicide in binge/purging subtypes need to be explored in future studies.
