A Wearable and Wirelessly Powered System for Multiple Finger Tracking

A wearable system that is capable of tracking finger motion and recognizing a set of hand gestures is presented. Two tracking units are worn on two fingers and are wirelessly powered without using cables or batteries, thus enhancing freedom of movement. The system is comprised of two sections: a measurement section and a wireless power transfer apparatus. The measurement section consists of two measuring devices placed on the thumb and index fingers. Each of these units can acquire and transmit sensor signals obtained from a stretch sensor and an inertial measurement unit. Furthermore, the wireless power transfer apparatus is implemented by means of inductively coupled resonant circuits. A relay-resonator configuration is employed to provide a homogeneous magnetic field in the operating volume of the system. A prototype of the developed system is characterized by experimental tests. Results show that the proposed approach is feasible. The measuring system can track finger movement with a sample rate of 30 Hz and recognize six predefined gestures used to control a robotic arm. The wireless power transfer apparatus demonstrates the capability of transferring 110 mW, necessary to power the measurement section, within an operating volume of 25 cm $\times20$ cm $\times15$ cm.
Prosociality, inhibitory control, social status and group norms in children and adolescents: psychological and socio-ecological perspectives

El objetivo de la presente investigacion fue (1) investigar la prosocialidad mediante el estudio de algunos de sus fundamentos psicologicos en ninos pequenos y (2) estudiar el papel de la prosocialidad en el contexto socio-ecologico de las relaciones entre pares en grupos de adolescentes jovenes. El trabajo comprendio dos estudios que profundizaron en un tema comun, la prosocialidad, abordada desde dos perspectivas diferentes pero complementarias. El Estudio 1 fue una investigacion experimental sobre la relacion entre una forma costosa de prosocialidad, como lo es el altruismo en la distribucion de recursos materiales, y un componente de la funcion ejecutiva, a saber, el control inhibitorio, en ninos pequenos de 4 a 6 anos de edad. El Estudio 2 fue una investigacion correlacional y abordo el efecto de las normas descriptivas de comportamientos prosociales y agresivos, ademas de la densidad de la red del grupo, sobre el impacto negativo de la victimizacion sobre la aceptabilidad (`likeability? ) en adolescentes jovenes de 13 anos. En el Estudio 1 participaron 72 ninos de 4 a 6 anos de edad de Colombia. Se evaluaron tres funciones ejecutivas: el control inhibitorio con la Tarea del Dia y la Noche, la memoria de trabajo con la Prueba de las Ocho Cajas Revueltas, y la flexibilidad cognitiva con la Clasificacion de Tarjetas de Cambio Dimensional. El comportamiento altruista se evaluo con el juego del Dictador (JD), que se jugo una sola vez y de forma anonima. En el Estudio 2 participaron 6.600 adolescentes de 13 anos de 269 aulas en 81 escuelas secundarias de Espana. Se evaluaron tres categorias de normas descriptivas definidas en funcion del tamano de los grupos (toda la clase, el subgrupo de los companeros mas visibles y el subgrupo de los mas aceptados), estas dos ultimas medidas corresponden a los constructos sociometricos de visibilidad y aceptabilidad. Los hallazgos descritos en el presente trabajo que el comportamiento altruista y la distribucion equitativa de recursos, tal como se evalua con un juego del Dictador, estan aun poco desarrollados en ninos de 4 a 6 anos de edad, y que la donacion voluntaria de recursos esta positivamente asociada con el control inhibitorio a esta temprana edad. Los resultados tambien revelan que las normas prosociales (y de agresion), principalmente del subgrupo de pares mas visibles (o populares), y la densidad de la red del aula, moderan el impacto negativo de la victimizacion de los pares sobre su aceptabilidad. Estos hallazgos fortalecen y amplian nuestra comprension de las relaciones entre pares, el estatus social y las relaciones entre comportamientos en grupos de adolescentes de 13 anos de edad. Las implicaciones teoricas y aplicadas de estos resultados se discuten en el contexto de investigacion de varias disciplinas, especialmente la psicologia del desarrollo y la psicologia comparada.
A qualitative evaluation of the acceptability and feasibility of a single visit approach to cervical cancer prevention in Ghana.

The main purpose of the two demonstration projects is to address the large unmet need for cervical cancer prevention services in resource-poor countries by testing a practical alternative to cytology-based screening. In Ghana where cervical cancer screening is infrequently performed Korle Bu Teaching Hospital in Accra reported that only approximately 1500 pap tests were completed in 1999 out of an estimated 327750 women aged 20-49 in the city of Accra (Ghana Statistical Service 2000). In addition access to a pap test does not guarantee treatment for women with positive test results due to a poor referral and follow-up infrastructure. The alternative approach that has been tested through the SAFE Demonstration Projects involves VIA followed by immediate cryotherapy treatment when indicated. This approach allows for an immediate management decision and action to be taken as appropriate. VIA is a simple procedure that consists of swabbing the cervix with vinegar waiting for one minute and looking at the cervix with a light source. Aceto-white areas near the squamo-columnar junction are suspected pre-cancerous lesions. Lesions occupying less than 75% of the cervix were considered eligible for immediate cryotherapy. In Ghana the demonstration project is referred to as Cervicare and was established at Ridge Hospital an urban hospital and at Amasaman Health Centre a peri-urban health center. Both are located in the Greater Accra Region. At Ridge Hospital the project tested and collected data on 3665 women from March 2001 to July 2002 and 13.2% tested positive for pre-cancer. At Amasaman Health Centre the project tested and collected data on 3206 women from January 2002 to July 2003 and 5.9% of women tested positive for pre-cancer. The majority of women with positive test results at both sites was eligible and chose to receive cryotherapy treatment. One year follow-up visits in both sites were ongoing at the time of this evaluation. All women provided their informed consent prior to testing and treatment. (excerpt)
A Review on Laboratory Diagnosis of Mycobacterium tuberculosis

Tuberculosis remains the major public health concern worldwide responsible for about 1.6 million deaths and 0.3 million co-infected with Human immunodeficiency virus (HIV) annually. Mycobacterium is the causative agent of tuberculosis infection and is transmitted principally through air when an infected person coughs, talks, sneezes etc. This infection can be diagnosed using different Microbiological, Molecular and Immunological techniques including, sputum smear microscopy, sputum culture, nucleic-acid amplification test (NAAT), genotyping assay, tuberculin skin test (TST), interferon-gamma release assay (IGRAs) etc. These techniques vary in sensitivity and specificity as well as the ease with which they are carried out. World Health Organisation (WHO) encourages the use of techniques that are sensitive, patient-friendly, and those which produce accurate results in any clinical setting world-wide. Hence, this review highlights smear microscopy and incorporation of more rapid and sensitive diagnostic techniques such as Gene Xpert, IGRAs and urinary antigen analysis in clinical setting in the detection of Mycobacterium. These techniques show high sensitivity, are less time consuming do not require a repeat for a single result, some are able to differentiate latent and active TB infections, and have the capacity to be used to screen people unable to expectorate. This review encourages the incorporation of smear microscopy, GeneXpert, IGRAs, urinary antigen analysis into routine laboratory diagnosis especially in high TB burden countries. It is believed that high level of sensitivity and less time used in producing results display by these techniques will yield reduction in mortality rate, decline in static nature of TB status and possibly zero TB 2020 proposed by WHO.
Sarilumab:A New Arsenal for Rheumatoid Arthritis

Rheumatoid arthritis is a debilitating disease that has significant impact on quality of life. Biological and non biological DMARDs improved the outcome in RA patients. New agents are still required in inadequate responders or intolerant patients. FDA has recently approved a new drug Sarilumab, a monoclonal antibody for the treatment of moderate to severe form of RA which acts by binding to Interleukin receptor 6 and interrupts the resultant cytokine-mediated inflammatory signaling.
Flexible and Structural Coloured Composite Films from Cellulose Nanocrystals/Hydroxypropyl Cellulose Lyotropic Suspensions

Lyotropic colloidal aqueous suspensions of cellulose nanocrystals (CNCs) can, after solvent evaporation, retain their chiral nematic arrangement. As water is removed the pitch value of the suspension decreases and structural colour-generating films, which are mechanically brittle in nature, can be obtained. Increasing their flexibility while keeping the chiral nematic structure and biocompatible nature is a challenging task. However, if achievable, this will promote their use in new and interesting applications. In this study, we report on the addition of different amounts of hydroxypropyl cellulose (HPC) to CNCs suspension within the coexistence of the isotropic-anisotropic phases and infer the influence of this cellulosic derivative on the properties of the obtained solid films. It was possible to add 50 wt. % of HPC to a CNCs aqueous suspension (to obtain a 50/50 solids ratio) without disrupting the LC phase of CNCs and maintaining a left-handed helical structure in the obtained films. When 30 wt. % of HPC was added to the suspension of CNCs, a strong colouration in the film was still observed. This colour shifts to the near-infrared region as the HPC content in the colloidal suspension increases to 40 wt. % or 50 wt. % The all-cellulosic composite films present an increase in the maximum strain as the concentration of HPC increases, as shown by the bending experiments and an improvement in their thermal properties.
Efficient Successive Over Relaxation Detectors for Massive MIMO

Massive multiple-input and multiple-output (MIMO) is considered as an advanced technique in wireless communication due to its high spectral efficiency, data rates, and transmission reliability. However, the large number of antennas makes it challenging to design efficient detectors since computational complexity is much higher. Thus, conventional linear methods like minimum mean square error (MMSE) detection suffer from prohibitive complexity. To balance complexity and performance, a class of iterative linear methods are considered to approach MMSE performance with <inline-formula> <tex-math notation="LaTeX">$\mathcal {O}({N_{T}}^{2})$ </tex-math></inline-formula> complexity, where <inline-formula> <tex-math notation="LaTeX">$N_{T}$ </tex-math></inline-formula> is the number of transmit antennas. Among them, successive over relaxation (SOR) detector is promising since it achieves near MMSE performance with affordable complexity and fast convergence. However, error performance of previously proposed SOR detectors is sensitive to a relaxation factor <inline-formula> <tex-math notation="LaTeX">$\omega $ </tex-math></inline-formula>, especially when the channel varies. To address this issue, two detectors are proposed in this paper: non-adaptive SOR (NA-SOR) detector (with fixed <inline-formula> <tex-math notation="LaTeX">$\omega $ </tex-math></inline-formula>) and adaptive SOR (A-SOR) detector (with iteratively changed <inline-formula> <tex-math notation="LaTeX">$\omega $ </tex-math></inline-formula>). Compared to prior SOR detectors, the performance of the NA-SOR detector is more robust to <inline-formula> <tex-math notation="LaTeX">$\omega $ </tex-math></inline-formula>, and the A-SOR detector achieves better performance, especially in highly correlated channels. An efficient pipelined hardware architecture of the A-SOR detector is proposed. Implementation results show advantages when compared to the state-of-the-art (SOA).

The Research Progress of Targeted Drug Delivery Systems

Targeted drug delivery system (DDS) means to selectively transport drugs to targeted tissues, organs, and cells through a variety of drugs carrier. It is usually designed to improve the pharmacological and therapeutic properties of conventional drugs and to overcome problems such as limited solubility, drug aggregation, poor bio distribution and lack of selectivity, controlling drug release carrier and to reduce normal tissue damage. With the characteristics of nontoxic and biodegradable, it can increase the retention of drug in lesion site and the permeability, improve the concentration of the drug in lesion site. at present, there are some kinds of DDS using at test phase, such as slow controlled release drug delivery system, targeted drug delivery systems, transdermal drug delivery system, adhesion dosing system and so on. This paper makes a review for DDS.
Switched-Capacitor and Coupled-Inductor-Based High Step-Up Converter With Improved Voltage Gain

Based on a hybrid technique of coupled inductor (CL) and switched capacitor, a high step-up dc–dc converter is developed in this article. It consists of one active switch, one CL, four diodes, and four capacitors. The active switch withstands low voltage stress and all diodes’ voltage stresses do not exceed half of the output voltage. Simple structure and low-voltage-rated switches contribute to high efficiency of the proposed converter. The converter provides the ideal voltage gain of (<inline-formula> <tex-math notation="LaTeX">$2 + 2\,\,n) /(1 - d)$ </tex-math></inline-formula>, here <inline-formula> <tex-math notation="LaTeX">$n$ </tex-math></inline-formula> represents the turns’ ratio of the CL and <inline-formula> <tex-math notation="LaTeX">$d$ </tex-math></inline-formula> is the duty ratio. Its circuit configuration and operation principle are introduced. Effects of leakage inductance of the CL and parasitic resistance of components are analyzed in detail. The experimental results demonstrate the effectiveness of the proposed converter and the maximum efficiency is above 97%.
The Influence Mechanism of Authentic Leadership in Artificial Intelligence Team on Employees’ Performance

The impact of Artificial Intelligence(AI) on industrial change has transformed the practice of enterprise management, and impacted the traditional management theory born in the industrial era. This paper discusses the impact of AI on the practice and theory of enterprise management, including the transparency of human beings and the employ ability of AI. Based on the characteristics of the AI technology development team. In this study, 102 AI technology team leaders and 697 team members from AI companies in China were used as subjects both to investigate the influence mechanism of AL at both the individual and team levels and to explore the cross-level relationship between the two levels. The results show that at the individual level, the psychological safety plays a mediating role between individual-oriented AL behavior and an individual’s performance. At the team level, the team’s atmosphere plays a mediating role between team-oriented AL behavior and the individual’s performance. This study has important implications for the theory of leadership behavior and leadership practice. AI belongs to a new type of technology, and the pressure of technology development work is great. It will display a kind of authentic leadership and can effectively promote the technology of the subordinates.
Análisis de costo-efectividad y costo-beneficio programa de detección temprana de cáncer gástrico en Costa Rica = Cost-effectiveness and cost-benefit analysis. gastric cancer early detection program in Costa Rica

In the first part of this study, the cost effectiveness of the early detection programme for gastric cancer in the Max Peralta hospital in Cartago (Costa Rica) en terms of dollars spent to save one life was determined. In the second part, a stated-preference method was employed, using surveys, which allows us to compare costs and benefits of this programme. We took the willingness to pay of the participants in this programme of the Caja Costarricense de Seguro Social as the basis for this analysis. If a comparison of the costs to save one life and the value of a statistical life saved were taken as a criterion for evaluating this programme, we would find a strong justification for this programme, if the productivity and effectiveness of the screening are sufficient. In order to reach this level of productivity and effectiveness, in terms number of members of high risk groups screened per day, several improvements in the organization of the programme are required. In case these improvements are not carried out, a weaker justification in terms of benefits for society for this programme exists. Nevertheless, we need to underline that a comparison of costs and benefits of this type should never be the only basis for a decision to continue this programme.
In situ SAXS of protein deposits in Alzheimer’s disease

Deposits of Aβ peptides (plaques) and tau protein (neurofibrillary tangles (NFTs)) are ubiquitous features of brain tissue in Alzheimer’s disease. Their contribution to disease etiology remains controversial. The molecular-to-nano-scale organization of fibrillar species in these protein aggregates remains uncertain, but may contain clues as to the contributions of these structures to disease. Whether or not all plaques are the same structure, and all tangles are the same, has implications for current hypotheses about polymorphic templated misfolding of their constituent proteins, Aβ and tau. Here we use x-ray microdiffraction in the small-angle regime (SAXS) to probe the molecular organization of these deposits. Using unstained histological sections of human brain tissue, we demonstrate that SAXS can characterize Aβ fibrils and tau filaments in situ. Aβ fibrils have a cross-sectional radius of gyration (Rxc) of ~45 Å, and larger (Rxc >150 Å) aggregates appear to represent Aβ fibrils that have coalesced side-to-side with one another to create fibrillar bundles or macrofibrillar aggregates. Tau fibrils exhibit an Rxc of ~55 Å with little sign of coalescence into larger structure. The in situ mapping of these structures revealed subtle variation in Aβ structure across different brain areas and different cases.
Application of multiscale fuzzy entropy features for multilevel subject-dependentemotion recognition

Emotion recognition can be used in clinical and nonclinical situations. Despite previous works which mostly used time and frequency features of electroencephalogram (EEG) signals in subject-dependent emotion recognition issues, we used multiscale fuzzy entropy as a nonlinear dynamic feature. The EEG signals of the well-known Database for Emotion Analysis Using Physiological signals dataset was used for classification of two and three levels of emotions in arousal and valence space. The compound feature selection with a cost of average accuracy of support vector machine classifier was used to reduce feature dimensions. For subject-dependent systems, the proposed method is superior in comparison to previous works with 90.81 % and 90.53 % accuracies in two-level classification and 79.83 % and 77.80 % accuracies in three-level classification in arousal and valence dimensions, respectively.
Genetic Testing for Late-Onset Disorders: The Experience of Machado-Joseph Disease in the Azores Islands (Portugal)

Machado-Joseph disease (MJD) (MIM 109150), also named spino-cerebellar ataxia type III (SCA3), is an autosomal dominant late-onset neurodegenerative disorder which involves the cerebellar, ocular motor, pyramidal, extrapyramidal and peripheral motor systems. Mean age at onset is 40.5 years, with extremes of 7 and 70 years; the estimated mean survival time is of 20 years (Coutinho, 1992). Detailed clinical investigation of the variability in MJD led to its classification into three phenotypes, which can be occasionally present in a single family, and constitute three clinical types, cerebellar ataxia and ophthalmoplegia being common to all of them. Type 1 has an early symptom onset (around 25 yr), and is additionally characterised by pyramidal signs and dystonic postures. Type 2 is the most common type and occurs around 40 yr, being dominated by ataxia and ophtalmoplegia, with or without pyramidal signs. Type 3 is later in onset (mean 47 yr) and progresses slowly with prominent amyotrophy (Coutinho and Andrade, 1978). Pathologically, the disease is characterized by degeneration of the spinocerebellar, dentate, pontine and vestibular nuclei as well as extra pyramidal structures. In addition, there
Distributed Self-Healing Scheme for Unbalanced Electrical Distribution Systems Based on Alternating Direction Method of Multipliers

With the advent of Smart Grids and advanced communication technologies, the self-healing scheme has become a desirable function of the operation and planning of electrical distribution systems (EDSs). In the presence of a permanent fault, an optimized self-healing scheme minimizes the unsupplied demand while maintaining the faulted section of the network isolated. The service restoration of the self-healing scheme is a combinatorial optimization problem whose computational complexity grows exponentially with the number of binary variables. To resolve this issue, a distributed optimal service restoration strategy is developed based on the alternating direction method of multipliers (ADMM). The service restoration problem is formulated as a mixed-integer second-order cone programming (MISOCP) problem. The decision variables of the problem are the status of the remote-controlled switches, load zones and load shedding at each controllable demand. Operational constraints, such as current and voltage magnitude constraints, distributed generation (DG) capacity constraints and radial topology constraints, are respected in the optimization problem. Through the ADMM, the optimization problem is distributed among the zones of the EDS, without requiring a central controller. Two test systems, an unbalanced 44-node system and the IEEE 123-node system, were used to conduct case studies. Results show that the proposed method can provide optimal service restoration solutions in reasonable time without a central controller.
