Learning from Adaptive Neural Control of Electrically-Driven Mechanical Systems

This study presents deterministic learning from adaptive neural control of unknown electrically-driven mechanical systems. An adaptive neural network system and a high-gain observer are employed to derive the controller. The stable adaptive tuning laws of network weights are derived in the sense of the Lyapunov stability theory. It is rigorously shown that the convergence of partial network weights to their optimal values and locally accurate NN approximation of the unknown closed-loop system dynamics can be achieved in a stable control process because partial Persistent Excitation (PE) condition of some internal signals in the closed-loop system is satisfied. The learned knowledge stored as a set of constant neural weights can be used to improve the control performance and can also be reused in the same or similar control task. Numerical simulation is presented to show the effectiveness of the proposed control scheme.
Wirkungen von Maßnahmen staatlicher Arbeitsmarkt- und Beschäftigungspolitik

Das immer drangender werdende Problem der Arbeitslosigkeit in Deutschland macht eine intensive Diskussion uber Ursachen der Arbeitslosigkeit und Moglichkeiten zu deren Bekampfung unabdingbar. Von vielen Seiten wird mehr denn je gefordert, das die staatliche Arbeitsmarkt- und Beschaftigungspolitik durch gezielte Masnahmen ein Ansteigen und eine weitere Verfestigung der Arbeitslosigkeit verhindern und Arbeitslose wieder in eine regulare Beschaftigung vermitteln soll. Das vorliegende Gutachten untersucht die Wirkungen der Arbeitsmarktpolitik und deren Moglichkeiten und Grenzen unter verschiedenen Aspekten, die fur eine wirtschaftspolitische Beurteilung relevant sind. Dabei stehen Masnahmen der Aktiven Arbeitsmarktpolitik im Vordergrund. Im ersten Teil des Gutachtens werden die wichtigsten Instrumente der Aktiven Arbeitsmarktpolitik in ihrer rechtlichen Ausgestaltung beschrieben und deren Einsatz in der Bundesrepublik seit 1970 dargestellt. Der zweite Teil beschaftigt sich mit der Wirkungsanalyse von Masnahmen der Aktiven Arbeitsmarktpolitik und diskutiert sowohl den makrookonomischen Zusammenhang zwischen AAMP und Beschaftigungs- und Lohnniveau und dessen empirische Evidenz als auch mikrookonomische Wirkungen der AAMP, insbesondere Qualifizierungsmasnahmen, auf die Beschaftigungs- und Einkommensentwicklung der Teilnehmenden. Besondere Aufmerksamkeit mus hierbei methodischen Problemen gewidmet werden. Desweiteren werden die Ergebnisse einer eigens fur dieses Gutachten unternommenen Wirkungsanalyse von Qualifizierungsmasnahmen in Sachsen vorgestellt und der Entwicklung fur Ostdeutschland insgesamt gegenubergestellt. Im dritten Teil schlieslich geht es um den Stellenwert von Aktiver und Passiver Arbeitsmarktpolitik und deren Anreizkompatibilitat. Eine ausfuhrliche Zusammenfassung schliest das Gutachten ab.
Editorial: Advances in Plant-Hemipteran Interactions

Hemipterans (e.g., aphids, whiteflies, stinkbugs, leafhoppers, and planthoppers) encompass a large group of insects with mouthparts specially modified for piercing and consuming fluids from the host (Capinera, 2008). Many hemipterans are important pests of plants and vector viral and bacterial diseases. Plant defenses against hemipterans include mechanisms that physically hinder insect feeding, as well as mechanisms that interfere with insect physiology and behavior (Painter, 1951; Kogan and Ortman, 1978; Smith, 2005). In some cases plants can alter their physiology to tolerate infestationwithout any detrimental effect on growth and development. Endosymbionts and phytopathogens present in the hemiptera impose an additional layer of organismal complexity to plant-hemipteran interactions. Considering the multiple organismal interactions involved, planthemipteran interaction studies have been conducted at different levels. This Research Topic brings together 16 manuscripts, which include a blend of reviews and research papers that address the physiology and molecular biology of plant-hemipteran interactions at these different levels.
Transesophageal Echocardiography in the Diagnosis of Acute Aortic Syndrome

Abstract In recent years, technological advances in echocardiography have led to improvements in the diagnosis of acute aortic disease. With transesophageal echocardiography (TEE) and, particularly, bi‐and multiplane probes, the physiopathologic understanding of these diseases has widened. Thus, new entities such as penetrating ulcer and intramural hematoma have been described and differentiated from classical aortic dissection.
Transport network architectures in an IP world

We develop a telecommunications architecture based on IP routers and compare it empirically to the current TDM hierarchy. The study is based on two premises: first that data traffic will continue to grow much faster than voice traffic and will be mostly IP, and second, that IP routers and networks will soon achieve the scalability and dependability necessary to provide the service quality expected of telecommunications networks. The IP architecture exploits a number of mechanisms to improve network efficiency: mesh restoration requires less spare bandwidth than SONET rings; private line services are carried as virtual leased lines, enabling more fine-grained bandwidth offerings; a voice subnetwork uses OC-48 links rather than DS-1 trunk groups, so it requires less total bandwidth to achieve the same blocking probability; and the multiplying inefficiencies of layer-by-layer routing in the TDM hierarchy are avoided. We find that an all-IP architecture could offer much greater network efficiency and considerable capital savings. We examine how technology must evolve to support such an architecture.
Therapeutic use of coenzyme Q10 and coenzyme Q10-related compounds and formulations

Importance of the field: Coenzyme Q10 (CoQ10) is found in blood and in all organs. CoQ10 deficiencies are due to autosomal recessive mutations, ageing-related oxidative stress and carcinogenesis processes, and also statin treatment. Many neurodegenerative disorders, diabetes, cancer and muscular and cardiovascular diseases have been associated with low CoQ10 levels, as well as different ataxias and encephalomyopathies. Areas covered in this review: We review the efficacy of a variety of commercial formulations which have been developed to solubilise CoQ10 and promote its better absorption in vivo, and its use in the therapy of pathologies associated with low CoQ10 levels, with emphasis in the results of the clinical trials. Also, we review the use of its analogues idebenone and MitoQ®. What the reader will gain: This review covers the most relevant aspects related with the therapeutic use of CoQ10, including existing formulations and their effects on its bioavailability. Take home message: CoQ10 does not cause serious adverse effects in humans and new formulations have been developed that increase CoQ10 absorption. Oral CoQ10 is a viable antioxidant strategy in many diseases, providing a significant to mild symptomatic benefit. Idebenone and MitoQ are promising substitutive CoQ10-related drugs which are well tolerated and safe.

[GI hemorrhage with fulminant shock induced by jejunal gastrointestinal stromal tumor (GIST) coincident with duodenal neuroendocrine carcinoma (NET) + neurofibromatosis (NF) -- case report and review of the literature].

BACKGROUND The incidence of neuroendocrine tumors (NET) and of gastrointestinal stromal tumors (GIST) is 0.5 and 1 - 2 in 100,000; the prevalence of neurofibromatosis is 1 in 3000 live births in Western countries. CASE REPORT A 43-year-old white woman with a six-month history of meleana, paleness, vertigo and fatigue was not referred to any gastrointestinal doctor for diagnostic work-up. Finally, she collapsed and was admitted to hospital because of an acute gastrointestinal bleeding. Endoscopically the source of bleeding could not be localized while blood in the duodenum and proximal jejunum was demonstrable. The source of bleeding could not be identified by endoscopy, CT scan or angiography. The patient developed a fulminant gastrointestinal hemorrhage with hemoglobin levels below 3.5 g %. An emergency laparotomy and pylorus-preventing Whipple operation was performed. Pathological studies showed a GIST with 3.5 cm diameter of the proximal jejunum which was the source of bleeding. Coincidentally a neuroendocrine carcinoma of the duodenum was found. CONCLUSION This case is the first presentation of the coincidence of a neuroendocrine carcinoma of the duodenum with a jejunal bleeding gastrointestinal stromal tumor in neurofibromatosis type1 which led to hemorrhagic shock. In neurofibromatosis -- even if non-symptomatic -- the increased incidence of tumor needs to be considered.
Modest salt intake reduction for 4 weeks or longer decreases blood pressure

Commentary on: He FJ, Li J, Macgregor GA. Effect of longer-term modest salt reduction on blood pressure. Cochrane Database Syst Rev 2013;4:CD004937 Hypertension is a primary cause of death and disability.1 Despite great strides in achieving BP targets, the majority of patients remain undertreated. Current recommendations include the dietary approaches to stop hypertension (DASH) diet and sodium reduction (6 g/day salt). 1 DASH-sodium is the sequel to the DASH study, as salt was not a factor originally.2 Reductions in the BP by decreasing salt, while not as impressive as with DASH, were still substantial. A reduction of 4 g/day of salt for …
A NovelS-Adenosyl-l-methionine:Arsenic(III) Methyltransferase from Rat Liver Cytosol*

S-Adenosyl-l-methionine (AdoMet):arsenic(III) methyltransferase, purified from liver cytosol of adult male Fischer 344 rats, catalyzes transfer of a methyl group from AdoMet to trivalent arsenicals producing methylated and dimethylated arsenicals. The kinetics of production of methylated arsenicals in reaction mixtures containing enzyme, AdoMet, dithiothreitol, glutathione (GSH), and arsenite are consistent with a scheme in which monomethylated arsenical produced from arsenite is the substrate for a second methylation reaction that yields dimethylated arsenical. The mRNA for this protein predicts a 369-amino acid residue protein (molecular mass 41056) that contains common methyltransferase sequence motifs. Its sequence is similar to Cyt19, a putative methyltransferase, expressed in human and mouse tissues. Reverse transcription-polymerase chain reaction detectsS-adenosyl-l-methionine:arsenic(III) methyltransferase mRNA in rat tissues and in HepG2 cells, a human cell line that methylates arsenite and methylarsonous acid.S-Adenosyl-l-methionine:arsenic(III) methyltransferase mRNA is not detected in UROtsa cells, an immortalized human urothelial cell line that does not methylate arsenite. Because methylation of arsenic is a critical feature of its metabolism, characterization of this enzyme will improve our understanding of this metalloid's metabolism and its actions as a toxin and a carcinogen.
Research on GPS attitude determination based on DPSO

GPS attitude determination is a key technology in aerospace, sailing and land-navigation etc. In the method of double difference phase measurement, it is a crucial topic to solve the carrier phase integer ambiguity, which is shown to be a combination optimization problem, and thus efficient heuristic algorithms are needed. In this paper, we propose a Discrete Particle Swarm Optimization (DPSO)-based solution which aims at searching for the optimal integer ambiguity directly without decorrelation of ambiguity, and computing the baseline vector consequently. A novel binary particle encoding approach and corresponding revision operation are presented. Furthermore, domain knowledge is incorporated to significantly improve the convergence rate. Through simulations, we demonstrate that the proposed algorithm is efficient for GPS attitude determination.
Mechanisms Associated with Corpus Luteum Development 1 f 2

The transition of a preovulatory follicle into a corpus luteum is a complex process involving mechanisms similar to wound healing and tumor formation. The objective of this review is to focus on mechanisms associated with corpus luteum development with specific attention to the follicular lineage of luteal cells, mechanisms associated with luteinization, and neovascular changes during luteal development. Corpora lutea are a continuation of follicular maturation and form from granulosal and theca interna cells. There is morphological and immunological evidence in ruminant species for the differentiation of granulosal and theca interna cells into large and small steroidogenic luteal cells, respectively. Different morphological, physiological, and biochemical characteristics of large and small luteal cells may reflect different follicular lineages with separate embryological origins. Following the preovulatory gonadotropin surge, follicular cells begin morphological, endocrinological, and biochemical changes associated with luteinization. Luteinization involves the transition of a preovulatory follicle into a highly vascular corpus luteum capable of secreting large quantities of progesterone. In addition, various cell types undergo hyperplasia, hypertrophy, and(or) migration during corpus luteum formation. An essential component of corpus luteum development is the recruitment of a blood supply. The development of a new microcirculatory bed involves breakdown of the follicular basement membrane, endothelial cell migration, endothelial cell proliferation, and development of capillary lumina. This process is regulated by the interaction of angiogenic and antiangiogenic substances. Further clarification of the preceding mechanisms may result in the development of improved methodologies for controlling the time of ovulation and(or) increasing pregnancy rates.
Improved algorithm for evaluation of lightning current using measured field at far distances from lightning channel

In this paper, the effect of radiation component of electric field on the total electric field at different distances with respect to lightning channel is considered. Results showed by approximating the total electric field with the radiation component at far and intermediate distances, some percentages of electric fields at different time periods will be neglected and this percentage will be higher when decreasing the distance from lightning channel. Whilst the most common inverse procedure algorithms are based on field's radiation component and the total field as input data, this paper proposed the same procedure that based on measured field with the consideration on the effect of radiation component on the total field in the calculations. The results on the prediction of channel base current illustrated that the proposed method is in very good agreement with real lightning channel base current compared to the corresponding predicted current based on existing methods.
Correlation between hypervolemia, left ventricular hypertrophy and fibroblast growth factor 23 in hemodialysis patients

Abstract Introduction: Left ventricular hypertrophy (LVH) is a significant risk factor for cardiovascular complications in hemodialysis (HD) patients. Hypervolemia has been accepted as an independent risk factor for progressive LVH in HD patients. Additionally, high FGF23 levels have been a significant predictor of cardiovascular mortality and morbidity in chronic kidney disease and HD patients. The aim of our study is to investigate the correlation among LVH, interdialytic volume increase and FGF-23 in the patients on a chronic hemodialysis program. Design and methods: A total of 97 chronic hemodialysis patients (64.43 ± 11.28 years old, M/F:47/50) were included in the study. Human FGF-23 ELISA kit was used for FGF-23 analysis of predialysis blood samples. Echocardiographic evaluation was performed in all of the patients after dialysis. Left Ventricular Mass Index (LVMI) was calculated by using the Devereux Formula. We collected the following data: LVMI, FGF-23 levels, interdialytic fluid gain, blood pressure changes, and the other biochemical and clinical parameters. Results: Mean LVMI of the patients was 184.41 ± 48.62 g/m2. LVMI of the patients with daily urine output >250 mL was found significantly lower. Statistically significant positive correlation was found between predialysis systolic blood pressure, predialysis diastolic blood pressure, predialysis mean arterial blood pressure and LVMI measurements (p < 0.01). Mean interdialytic volume excess was correlated with LVMI measurements of the patients (r = 0.459; p < 0.01). Increased FGF-23 levels (159.79 ± 134.99 ng/L) predicted increased LVMI measurements of the patients (r = 0.322; p < 0.01). In addition, FGF-23 levels were also increased as the interdialytic fluid volume increased (r = 0.326; p < 0.05). A positive correlation was also found between FGF-23 levels and interventricular septum thickness (r = 0.238; p < 0.05). Predialysis mean arterial blood pressure, predialysis volume overload and presence of diabetes were determined to be independent risk factors on LVMI on multivariate regression analysis. Conclusion: Our study showed that interdialytic volume overload increased both LVMI and FGF-23 values. We can consider that interdialytic volume control exerts positive effects on increased FGF-23 levels which predict the negative cardiovascular outcomes.
El Estado, la empresa y la restauración del paradigma neoclásico

El autor caracteriza la restauracion neoclasica que, a partir de los anos setenta, confronto radicalmente la posibilidad de una teoria del desarrollo, al buscar disolver las especificidades de las economias en desarrollo en la unidad de las ideas centrales de la teoria economica. Las intervenciones dirigidas a favorecer el desarrollo se conceptualizaron, no como solucion, sino como parte del problema. Por otra parte, mas que a corregir desequilibrios, los programas de ajuste apuntaron a la configuracion de una economia cercana a las prescripciones neoclasicas. Se eligio a varias economias del Este de Asia como ejemplos de aplicacion de las politicas correctas, ya que eran guiadas por el mercado. Sin embargo, la profundizacion del estudio de dichas experiencias permitio concluir que detras del exito exportador estaba la mano firme y orientadora del Estado. Pero, mas alla de la controversia entre mercado y Estado, en el debate ha faltado la consideracion de los actores principales: las empresas. La vision de las empresas como agentes que reaccionan solo a un conjunto de oportunidades es limitada, ya que desconsidera el analisis de como la empresa aprende y, posiblemente, cambia frente a situaciones diversas. En este sentido convendria reexaminar el balance de costos y beneficios de la promocion industrial en los paises en desarrollo. Tambien convendria analizar en mas detalle la actual redefinicion de las empresas, en el marco de las nuevas condiciones. El autor concluye senalando la necesidad de profundizar el estudio de las empresas, las que no fueron titeres de las politicas publicas ni seran automatas del mercado.
Un bébé androïde vocalisant : étude et modélisation des mécanismes d'exploration vocale et d'imitation orofaciale dans le développement de la parole

L'exploration vocale et l'imitation orofaciale sont vraisemblablement necessaires au developpement de la production verbale. Une revue de questions transdisciplinaire sur l'imitation nous a permis de proposer de nouvelles hypotheses sur la co-structuration des domaines perceptif et moteur dan~ l'emergence de la production de la parole ambiante. Pour simuler de maniere realiste l'imitation et l'exploration, un agent sensorimoteur a ete concu a base de modeles computationnels de la production de la parole dans un conduit vocal en croissance, de sa perception audio-visuo-somesthesique, et de l'apprentissage de liens entre ses domaines articulatoire et perceptif. Par cette plate-forme experimentale virtuelle, le processus d'exploration a ete simule avant (a 4 mois) et au debut (a 7mois) du babillage, celui d'imitation l'a ete a 4 mois. Dans le premier cas, nous avons cherche a estimer, dans une analyse par modelisation, les capacites articulatoires des nourrissons d'apres des mesures acoustiques decrivant leurs vocalisations, et tester des hypotheses formulees dans le domaine de la parole sur le developpement precoce du controle du systeme articulatoire. L'imitation a ete implementee sous la forme d'un modele probabiliste qui apprend des elements issus de l'espace d'exploration estime a 4 mois. La carte des liens perceptionproduction qui en resulte a ete utilisee pour simuler une experience (tiree de la litterature) sur l'imitation precoce de voyelles [i a u]. Nous avons cherche a reproduire les performances accomplies par les nourrissons, pour interroger les caracteristiques de la carte cognitive et de l'apprentissage potentiellement en jeu dans ce comportement.
Near Real-Time Risk Simulation of Complex Portfolios on Heterogeneous Computing Systems with OpenCL

High-performance computing systems are highly required nowadays in financial risk analysis and management, which has become a key process at the core of financial institutions. Risk metrics such as portfolio value-at-risk and expected shortfall are computed on a daily basis. In this regard, the most general and flexible approach is a nested Monte Carlo simulation, which is very compute-intensive. In this work, we exploit the Open Computing Language (OpenCL) to efficiently map the nested simulation of complex portfolios with multiple algorithms on heterogeneous computing systems, maximizing system-level performance. The code portability and individual customizations allow us to profile the kernels on different accelerating platforms, such as CPU, Intel's Xeon Phi, and GPU. The combination of OpenCL, a new bit-accurate algorithmic optimization, and the extension of an existing numerical scheme using interpolation, allows us to achieve over 1000x speedup compared to the state-of-the-art approach, making this approach even feasible for intraday risk analysis. Our proposed system design also minimizes costly host-device data transfers and the required device global memory, enabling complex portfolios to be easily scaled.
Applying Time-Series Regression to Load Forecasting Using Neuro-Fuzzy Techniques

This paper provides an intelligence method for medium and long-term energy demand forecasting of a complicated electrical system. In this method we use energy data of several past years to train an Adaptive Network based on Fuzzy Inference System (ANFIS). We use this intelligence network to estimate the time series behaviour of energy consumption for several future years. Several simulations have been arranged to examine the efficiency of method.
