Predicción de actividades de la vida diaria en entornos inteligentes para personas con movilidad reducida

Las actividades de la vida diaria (AVD) son aquellas actividades orientas al cuidado, productividad y ocio. Las tareas basicas de una persona, que consisten en el cuidado personal, se pueden ver afectadas por una enfermedad degenerativa o el sufrimiento de un accidente cerebrovascular. Por este motivo, el proyecto “Adaptive Multimodal Interfaces to Assist Disabled People in Daily Activities (AIDE)” pretende realizar un sistema multimodal capaz de extraer informacion relevante del comportamiento e intencion del usuario, extraer informacion de las capacidades motoras residuales y del analisis del entorno con el objetivo de mejorar la independencia de estas personas. Para ello se ha realizado el estudio de dos tecnicas de aprendizaje automatico: campos aleatorios condicionales (CRF) y redes neuronales temporales (TDNN), para predecir la actividad que el usuario desea realizar estudiando tambien la adaptacion de los metodos a la rutina del usuario. De este modo, y usando un entorno virtual, se ha adquirido la informacion necesaria de un usuario durante cinco dias bajo las condiciones del proyecto AIDE obteniendo una tasa de acierto de mas del 90 % en ambos metodos, llegando al 100 % de precision en algunas actividades usando CRF. Por lo tanto, mediante esta tecnica seremos capaces de ayudar a estas personas actuando sobre el hogar, adaptandonos a sus necesidades y rutinas.
Minimizing and managing bleeding after percutaneous nephrolithotomy

Purpose of review As urologists will continue to rely on percutaneous nephrolithotomy, a clear understanding of its associated bleeding risks and management is mandatory. Recent findings Despite advances in lithotripsy technology, bleeding continues to be a cause of patient morbidity in percutaneous nephrolithotomy. Although most patients can be managed conservatively, a subset of patients will require endovascular embolization for vascular control. Investigators have identified risk factors and described management options. The use of different dilators and tract size continues to be examined. Additionally, novel applications of proclotting agents as well as direct renal and tract electrocauterization immediately postpercutaneous nephrolithotomy have been reported to decrease transfusions. Finally, initial access obtained by the urologist is associated with less bleeding and higher stone-free rates. Summary Optimal renal access is the most critical factor influencing surgical success and minimizing overall blood loss. Although real-time ultrasonography may add to the safety of the initial access, surgeon experience is the key factor. As such, the urologist must be actively involved in tract placement. Clinically significant bleeding can be treated conservatively in a majority of cases with tamponade nephrostomy tubes with or without transfusions. Arterial hemorrhage, pseudoaneurysms, and arterial-venous fistulas, however, require prompt intervention with angiographic embolization.
SEARCHING FOR THE MEANING OF MEANING: GRIEF THERAPY AND THE PROCESS OF RECONSTRUCTION

A comprehensive quantitative review of published randomized controlled outcome studies of grief counseling and therapy suggests that such interventions are typically ineffective, and perhaps even deleterious, at least for persons experiencing a normal bereavement. On the other hand, there is some evidence that grief therapy is more beneficial and safer for those who have been traumatically bereaved. Beginning with this sobering appraisal, this article considers the findings of C. G. Davis, C. B. Wortman, D. R. Lehman, and R. C. Silver (this issue) and their implications for a meaning reconstruction approach to grief therapy, arguing that an expanded conception of meaning is necessary to provide a stronger basis for clinical intervention.
Local governance and efficiency of conditional cash transfers: Bolsa Escola in Brazil

Conditional cash transfer programs, initially managed centrally, are increasingly relying on municipal roles for beneficiary selection and program implementation. We use a rigorous identification of program efficiency at the municipal level to establish the municipal correlates that matter for performance. Brazil’s Bolsa Escola program offered transfers to poor mothers in exchange for regular school attendance, with municipalities in charge of beneficiary selection and the enforcement of conditionalities. On average, the program reduced the drop-out rate by 7.8% points (from a drop out rate of 17% without the program) but increased grade failure by 0.8% points (from a grade failure of 13% without the program), resulting in a net decline of 6.2% in grade retention. Performance, however, varied widely across municipalities. Municipal characteristics associated with greater program impact on reduced drop-out show the positive effects of more competitive democratic processes, political rewards for incumbent mayors, greater transparency in beneficiary selection, and stricter enforcement of conditionalities. Based on differential interpretation of rules across municipalities, we find that decentralized selection of beneficiaries fared no worse in program efficiency than centralized selection.

Abstract Waarnemingen.be - Plant occurrences in Flanders and the Brussels Capital Region, Belgium is a species occurrence dataset published by Natuurpunt. The dataset contains almost 1.2 million plant occurrences of 1,222 native vascular plant species, mostly recorded by volunteers (citizen scientists), mainly since 2008. The occurrences are derived from the database http://www.waarnemingen. be, hosted by Stichting Natuurinformatie and managed by the nature conservation NGO Natuurpunt. Together with the datasets Florabank1 (Van Landuyt and Brosens 2017) and the Belgian IFBL (Instituut voor Floristiek van België en Luxemburg) Flora Checklists (Van Landuyt and Noé 2015), the dataset represents the most complete overview of indigenous plants in Flanders and the Brussels Capital Region.
Chromium in food products

Chromium plays an important role in human and animal bodies. According to the oxidation state chromium can be advantageous for human health and, simultaneously possesses toxic properties. In this work the studies concerning the chromium content in the total and Cr (VI) forms in selected and frequently used during breakfast food products were presented. The largest quantities of the metal occur in raw cereal products (non-roasted buckwheat or brown rice bread) and herbs such as garlic or mint. The lowest chromium contents were observed in raw and UHT milk samples.
ADMISSIBLE CLUSTERING OF AGGREGATOR COMPONENTS: A NECESSARY AND SUFFICIENT STOCHASTIC SEMINONPARAMETRIC TEST FOR WEAK SEPARABILITY

In aggregation theory, the admissibility condition for clustering components to be aggregated is blockwise weak separability, which also is the condition needed to separate out sectors of the economy. Although weak separability is thereby of central importance in aggregation and index number theory and in econometrics, prior attempts to produce statistical tests of weak separability have performed poorly in Monte Carlo studies. This paper introduces a new class of weak separability tests, which is seminonparametric. Such tests are both based on a necessary and sufficient condition and are fully stochastic, allowing to take into account measurement error. Simulations show that the tests perform well, even for large measurement errors.
Characteristics and Treatment of Headache After Traumatic Brain Injury: A Focused Review

Lew HL, Lin P-H, Fuh J-L, Wang S-J, Clark DJ, Walker WC: Characteristics and treatment of headache after traumatic brain injury: A focused review. Am J Phys Med Rehabil 2006;85:619–627. Headache is one of the most common complaints in patients with traumatic brain injury. By definition, headache that develops within 1 wk after head trauma (or within 1 wk after regaining consciousness) is referred to as posttraumatic headache (PTH). Although most PTH resolves within 6–12 mos after injury, approximately 18–33% of PTH persists beyond 1 yr. We performed a systematic literature review on this topic and found that many patients with PTH had clinical presentations very similar to tension-type headache (37% of all PTH) and migraine (29% of all PTH). Although there is no universally accepted protocol for treating PTH, many clinicians treat PTH as if they were managing primary headache. As a result of the heterogeneity in the terminology and paucity in prospective, well-controlled studies in this field, there is a definite need for conducting double-blind, placebo-controlled treatment trials in patients with PTH.
Electron microscopy of human cerebral aneurysms.

Printed Planar 8  $\times$ 8 Array Antenna With Circular Polarization for Millimeter-Wave Application

A new type of printed millimeter planar antenna with circular polarization for 60-GHz range is proposed. Radiation elements with two open tape rings are arranged in a two-dimensional 8×8 antenna array. Feeding is synphase network with tapered symmetrical (balanced) microstrip in the same plane as the radiation elements. The 8×8 array is fabricated in the conventional technology. To test reproducibility, three samples are fabricated. Measured S11 (VSWR), gain, and axial ratio (AR) are very good and in very good agreement between all three samples: AR<;3 dB about 25% and gain near 20 dBi.
Open Issues in Evolutionary Robotics

Abstract One of the long-term goals in evolutionary robotics is to be able to automatically synthesize controllers for real autonomous robots based only on a task specification. While a number of studies have shown the applicability of evolutionary robotics techniques for the synthesis of behavioral control, researchers have consistently been faced with a number of issues preventing the widespread adoption of evolutionary robotics for engineering purposes. In this article, we review and discuss the open issues in evolutionary robotics. First, we analyze the benefits and challenges of simulation-based evolution and subsequent deployment of controllers versus evolution on real robotic hardware. Second, we discuss specific evolutionary computation issues that have plagued evolutionary robotics: (1) the bootstrap problem, (2) deception, and (3) the role of genomic encoding and genotype-phenotype mapping in the evolution of controllers for complex tasks. Finally, we address the absence of standard research practices in the field. We also discuss promising avenues of research. Our underlying motivation is the reduction of the current gap between evolutionary robotics and mainstream robotics, and the establishment of evolutionary robotics as a canonical approach for the engineering of autonomous robots.
Parameter extraction for sound synthesis of the Dan Tranh

This paper describes a parameter extraction system for tone synthesis of the Dan Tranh, a Vietnamese string instrument, using partial decay estimation and single delay loop model. The parameters of the string model are estimated and the excitation signals for the model are extracted from recorded tones. The quality of synthesized tones is also studied based on different recorded data, numerous analyzed partials, amplitude normalization and changing parameters of short-time Fourier transform. The result is also compared with the Korean Gayageum.
A moderately thermophilic ammonia-oxidizing crenarchaeote from a hot spring

The recent discovery of ammonia-oxidizing archaea (AOA) dramatically changed our perception of the diversity and evolutionary history of microbes involved in nitrification. In this study, a moderately thermophilic (46°C) ammonia-oxidizing enrichment culture, which had been seeded with biomass from a hot spring, was screened for ammonia oxidizers. Although gene sequences for crenarchaeotal 16S rRNA and two subunits of the ammonia monooxygenase (amoA and amoB) were detected via PCR, no hints for known ammonia-oxidizing bacteria were obtained. Comparative sequence analyses of these gene fragments demonstrated the presence of a single operational taxonomic unit and thus enabled the assignment of the amoA and amoB sequences to the respective 16S rRNA phylotype, which belongs to the widely distributed group I.1b (soil group) of the Crenarchaeota. Catalyzed reporter deposition (CARD)–FISH combined with microautoradiography (MAR) demonstrated metabolic activity of this archaeon in the presence of ammonium. This finding was corroborated by the detection of amoA gene transcripts in the enrichment. CARD-FISH/MAR showed that the moderately thermophilic AOA is highly active at 0.14 and 0.79 mM ammonium and is partially inhibited by a concentration of 3.08 mM. The enriched AOA, which is provisionally classified as “Candidatus Nitrososphaera gargensis,” is the first described thermophilic ammonia oxidizer and the first member of the crenarchaeotal group I.1b for which ammonium oxidation has been verified on a cellular level. Its preference for thermophilic conditions reinvigorates the debate on the thermophilic ancestry of AOA.
Involvement of the FGFR4 Arg388 allele in head and neck squamous cell carcinoma

Fibroblast growth factor receptors (FGFRs) have been implicated in various forms of human hyperproliferative disorders such as cancers of the cervix and bladder. We investigated the expression pattern of FGFR4 and the clinical significance of the recently identified Gly/Arg polymorphism (388) in head and neck squamous cell carcinomas (HNSCCs) of the oral cavity and the oropharynx. Sections from 104 paraffin‐embedded tumors were analyzed by a restriction fragment length polymorphism‐based method to determine the FGFR4 genotypes. Protein expression was investigated immunohistochemically and graded into a low, intermediate, or high degree of staining. FGFR4 expression was scored as high in 17, as intermediate in 59 and as low in 28 cases. The FGFR4 Arg388 allele was found in 59 tumors, 46 of them having heterozygous and 13 homozygous genotypes. High expression of the FGFR4 Arg388 allele was significantly associated with reduced overall survival (p = 0.032) and with an advanced tumor stage (p = 0.023), whereas expression of the FGFR4 Gly388 had no impact on disease progression. Our findings indicate that high expression of FGFR4 in connection with the Arg388 allele is associated with poor clinical outcome and support the significance of FGFR4 as a diagnostic marker and a target for therapeutic intervention in human HNSCC. © 2004 Wiley‐Liss, Inc.
Oestrogen relaxes human epicardial coronary arteries through non‐endothelium-dependent mechanisms

BackgroundOestrogen-replacement therapy is associated with a reduced incidence of cardiovascular disease. The acute administration of oestrogen improves myocardial ischemia in women with coronary heart disease. In this study we investigated the relaxing effect of oestradiol-17β on human coronary arteries in vitro and determined the role of endothelial modulation in this relaxation by using isolated human coronary arteries. MethodsAtherosclerosis-free epicardial arteries from men and women were removed from patients undergoing heart or combined heart and lung transplantation. The arteries were cut into ring segments and placed into organ baths containing Tyrode's solution. Changes in isometric tension were measured. The relaxing response to oestradiol-17β (10-10-10-5mol/l) was investigated and the effects of endothelium, NGmonomethyl-L-arginine and indomethacin on the response of oestradiol-17β were assessed. ResultsOestradiol-17β (10-10-10-5mol/l) induced significant relaxation in coronary arteries pre-contracted with the thromboxane A2 analog (U46619; 3 × 10-8mol/l). Relaxation was significantly greater in coronary arteries from female patients. No significant differences were observed between arteries with or without endothelium nor after nitric oxide synthase or cyclo-oxygenase inhibition. These results indicate that oestradiol-17β induces human coronary artery relaxation via an endothelium-independent mechanism in vitro. The sex of the patients significantly affects sensitivity of the coronary arterial rings to oestrogen. ConclusionOestradiol-17β-induced coronary relaxation may play an important role in the regulation of coronary tone, and may partly explain why oestrogen improves myocardial ischemia in women and why it protects postmenopausal women from the risk of developing coronary heart disease.
Design of model-based controllers applied to a solid-state low voltage dc breaker

This paper presents the methodology of design of model-based sliding mode control (SMC) algorithms applied to power electronic dc-dc converters, which are part of the components of a solid-state low voltage dc breaker (SLVDB). The power converters used in the tested schemes of the SLVDB are the boost and sepic dc-dc converters. Accurate disconnection times, user-configured, are achieved with the proposed controllers, as well as a complete minimization of the transient recovery voltage (TRV) in the breaker terminals. Details of the performance of two SLVDB configurations are analyzed and compared in order to establish the best design comprising complexity vs. performance. MATLAB simulations support the results and provide a reasonable picture of the operation of the SLVDB.
A VLSI-Suitable Schottky-Barrier CMOS Process

Trenched Schottky-barrier (TSB) contact PMOS devices for use in latchup-free CMOS are examined in detail, and compared to Schottky-contact PMOS. Measurements and simulations show that the TSB structure has significant advantages in gain and current leakage over the Schottky-contact structure, CMOS using TSB PMOS may be made unconditionally free of Iatchup. The tradeoffs involving PMOS source-drain implant dose are made explicit and correlated to Iatchup measurements.
Multiscale Product Riesz Wavelet for Color Edge Detection in Hilbert Domain

This paper proposes an edge detection technique based on the Multiscale Product of Riesz Wavelet Transform for color image. The product of the wavelet transform combines the advantages of the used scales: in large scale it is strongly anti-noise, and in small scale it can accurately locate edge. The Riesz wavelet transform is a complex wavelet transform (WT) which comes to overcome the discrete wavelet transform (DWT) shortcomings. The WT presents important additional properties. It is nearly shift invariant and directionally selective in two and higher dimensions. Computer simulations are performed on noise free as well as on noisy images. Comparisons with other edge detectors give improvement for the proposed edge detection technique.
Concise Review: Putting a Finger on Stem Cell Biology: Zinc Finger Nuclease‐Driven Targeted Genetic Editing in Human Pluripotent Stem Cells

Human pluripotent stem cells (hPSCs) encompassing human embryonic stem cells and human induced pluripotent stem cells (hiPSCs) have a wide appeal for numerous basic biology studies and for therapeutic applications because of their potential to give rise to almost any cell type in the human body and immense ability to self‐renew. Much attention in the stem cell field is focused toward the study of gene‐based anomalies relating to the causative affects of human disease and their correction with the potential for patient‐specific therapies using gene corrected hiPSCs. Therefore, the genetic manipulation of stem cells is clearly important for the development of future medicine. Although successful targeted genetic engineering in hPSCs has been reported, these cases are surprisingly few because of inherent technical limitations with the methods used. The development of more robust and efficient means by which to achieve specific genomic modifications in hPSCs has far reaching implications for stem cell research and its applications. Recent proof‐of‐principle reports have shown that genetic alterations with minimal toxicity are now possible through the use of zinc finger nucleases (ZFNs) and the inherent DNA repair mechanisms within the cell. In light of recent comprehensive reviews that highlight the applications, methodologies, and prospects of ZFNs, this article focuses on the application of ZFNs to stem cell biology, discussing the published work to date, potential problems, and future uses for this technology both experimentally and therapeutically.

Reduction of Cytochrome aa3 Measured by Near-Infrared Spectroscopy Predicts Cerebral Energy Loss in Hypoxic Piglets

ABSTRACT: Near-infrared spectroscopy is a noninvasive monitoring technique that allows quantitative measurement of changes in cerebral oxygenated Hb (HbO2), deoxygenated Hb (Hb), total Hb, and oxidized cytochrome aa3 (CytO2). Changes in cerebral Hb oxygenation and CytO2 have been measured in human neonates and infants under a variety of conditions. However, the association of these measurements with cerebral high-energy phosphate loss is not known. We studied simultaneous changes in cerebral HbO2, Hb, total Hb, and CytO2 by near-infrared spectroscopy and changes in nucleoside triphosphate (NTP, mostly ATP) and phosphocreatine (PC) concentrations and intracellular pH by in vivo 31P-labeled magnetic resonance spectroscopy. Four-wk-old piglets (n = 8) underwent sequential hypoxic episodes of increasing severity (inspired O2 concentration, 12, 8, 6, 4, and 0%). Animals were anesthetized and mechanically ventilated. At all levels of hypoxia, cerebral HbO2 decreased, and Hb increased. Loss of PC or NTP was not observed until inspired O2 concentration was decreased to less than 12%. With such severe hypoxia, hypotension, intracellular acidosis, and increasingly severe PC and NTP depletions occurred. Decreases in PC and NTP correlated closely with decreased CytO2 and arterial blood pressure (p < 0.0001) but not with changes in HbO2 and Hb. In conclusion, cerebral hypoxemia is readily detected by near-infrared spectroscopy as a decrease in HbO2 and an increase in Hb. However, relative changes in cerebral HbO2 and Hb have low predictive value for cerebral energy failure. Reduction of CytO2 is highly correlated with decreased brain energy state and may indicate impending cellular injury.
