Slow speed resistance exercise training in children with polyarticular juvenile idiopathic arthritis

Background: Juvenile idiopathic arthritis (JIA) is an inflammatory autoimmune disease that can cause severe impairment and disability. Exercise is recommended to preserve joint mobility and function. Our objectives were to assess the safety, feasibility, and effects of slow speed resistance exercise in children with polyarticular JIA. Methods: Patients were recruited from a pediatric rheumatology clinic at an urban hospital and randomized to exercise or control groups. In the intervention group, slow speed resistance exercise with individualized instruction by a certified trainer was performed 1–2 times per week for 12 weeks. The control group performed home-based aerobic exercise 3 days per week for 12 weeks. Pre and post-body composition measurements by dual-energy X-ray absorptiometry; aerobic fitness by peak oxygen uptake during cycle ergometry; isometric muscle strength; and quality of life measures were obtained. Results: In the exercise group, 9/17 (53%) completed any exercise training. Of these nine subjects, five (55%) completed all 12 weeks of the protocol. In the control group, 8/16 (50%) reported compliance with the recommended aerobic exercise training at least one time per week. Only 2 subjects (12%) reported exercising more than once per week. There was no significant difference between pre- and post-measurements in any category in the exercise group. There was also significantly elevated body fat in both groups with only 17% in the control group and 23% in the exercise group meeting recommended <30% total body fat levels. Conclusions: Children with JIA participated safely in this resistance exercise protocol. The exercise was well-tolerated with no serious adverse events noted. While individual subjects reported improvement in fatigue and improved energy, there was no statistical difference in pre- and post-exercise measures of body composition or quality of life. Identifying ways to improve adherence and encourage exercise in children with JIA is important.
Professional Directors and Governance Quality

We examine professional directors—board members with no employment outside of serving as independent directors. We find that boards with a higher percentage of professional directors engage in more acquisitions, experience lower acquisition announcement returns, and exhibit lower performance‐turnover sensitivity and lower financial performance. We also examine the returns surrounding the appointment‐announcement dates of professional directors and find that firms experience significantly lower cumulative abnormal returns upon the appointment announcement of professional directors as compared to nonprofessional directors. The negative returns are primarily experienced by firms that face greater agency issues, suggesting that the market does not value professional directors for stricter monitoring. Overall, our findings do not lend support for calls to professionalize corporate boards. Administrateurs professionnels et qualite de la gouvernance Les auteures se penchent sur les administrateurs professionnels, soit ceux qui n'ont d'autre emploi que celui de sieger a des conseils d'administration a titre d'administrateurs independants. Elles constatent que les conseils d'administration qui comptent un pourcentage d'administrateurs professionnels plus eleve procedent a un plus grand nombre d'acquisitions, tirent des annonces d'acquisition des rendements moins importants et affichent une sensibilite moins grande a la performance et a la rotation des administrateurs de meme qu'une performance financiere plus faible. Les auteures etudient egalement les rendements a proximite des dates d'annonce de nominations d'administrateurs professionnels et constatent que les societes enregistrent des rendements anormaux cumulatifs sensiblement moins eleves lorsqu'elles annoncent la nomination d'administrateurs professionnels que lorsqu'elles annoncent celle d'administrateurs non professionnels. Les rendements negatifs sont principalement enregistres par les societes qui sont aux prises avec davantage de problemes de delegation, ce qui donne a penser que le marche n'attache pas de valeur au fait que les administrateurs professionnels puissent exercer une surveillance plus rigoureuse. Dans l'ensemble, les resultats de l'etude ne justifient pas que l'on reclame la professionnalisation des conseils d'administration d'entreprises.
Phylogenetic Analysis of Tetragonula Minangkabau and Other Species Using Cytochrome B Gene

Abstract Tetragonula a genus in the Meliponini tribe (Apidae), is difficult to identify due to the many cryptic species. As technology develops, molecular taxonomic studies are used to help identify species with limited morphological characteristics. This study presents an analysis of the phylogenetic relationship between several species in the Tetragonula genus based on the sequences of the cytochrome b gene. Maximum parsimony, neighbor joining, maximum likelihood and minimum evolution methods were used to construct phylogenetic trees. The sequence divergence between T. minangkabau collected from Limau Manis and Ulu Gadut is 0.8%, while between T. minangkabau with T. minangkabau forma darek 5.5%. The low sequence divergence indicated that T. minangkabau and T. minangkabau forma darek have a close phylogenetic relationship. The analysis showed that Tetragonula (T. minangkabau, T. minangkabau forma darek, T. laeviceps, T. drescheri and T. fuscobalteata) is monophyletic. A sequence divergence of 5.5% supports the separation of Tetragonula minangkabau and T. minangkabau forma darek.
Design of Robust PID Controllers Using H∞ Technique to Control the Frequency of Wind-Diesel-Hydro Hybrid Power System

This paper proposes and provides the design steps of three robust output feedback controllers to control the frequency of Wind-Diesel-Hydro hybrid system. The first presents a centralized robust based H∞ (CRH∞) controller. The role of H∞ is to minimize the disturbance effect on the system output. The effect of the LMI tuning variables of RH∞ controller on the system dynamic performance is presented and discussed. The controllers are solved using the Linear Matrix Inequalities (LMI) technique and characterized by a similar size as the plant that may be of higher order and thus creates difficulty in implementation in large systems. The second presents decentralized robust based H∞ for each unit (DRH∞). The third is robust PID controllers which are ideally practical for industry and more appealing from an implementation point of view since its size is lower. The optimum parameters of the robust PID controllers are found through the optimization by a novel combination of RH∞ control theories through the Genetic Algorithm (GA) technique. More specifically, the third robust PID controllers are proposed to achieve the same robust performance as decentralized (DRH∞) controllers, respectively. All controllers are used as load frequency controllers to control the Wind-Diesel-Hydro hybrid system . Comparisons of the performance of the three robust output feedback controllers under diverse tests in different disturbances and variation in the plant parameters are carried out.
Gastrointestinal Involvement in Granulomatosis with Polyangiitis: Case Report and Review

Granulomatosis with polyangiitis (GPA) commonly affects upper/lower respiratory tract and kidneys. It causes necrotizing vasculitis of small and medium-sized blood vessels. Gastrointestinal (GI) involvement is an uncommon manifestation of GPA, and presentation with predominant GI manifestation is noteworthy. We report a case of 50-year-old male with melena due to GI vasculitis along with other systemic involvement. The patient was treated with pulse methylprednisolone, cyclophosphamide, and plasmapheresis. To manage the refractory GI bleed, the patient underwent surgical resection, and the histology of the surgical specimen confirmed necrotizing vasculitis.

Synchrophasor-based Fault Location Detection and Classification, in Power Systems, using Artificial Intelligence

With the introduction of sophisticated electronic gadgets which cannot sustain interruption in the provision of electricity, the need to supply uninterrupted and reliable power supply, to the consumers, has become a crucial factor in the present-day world. Therefore, it is customary to correctly identify fault locations in an electrical power network, in order to rectify faults and restore power supply in the minimum possible time. Many automated fault location detection algorithms have been proposed, however, prior art requires topological and physical information of the electrical power network. This thesis presents a new method of detecting fault locations, in transmission as well as distribution networks, using state-ofthe-art machine learning algorithms on the real-time synchrophasor measurements obtained from the network. The proposed method first generates a bus admittance matrix from the synchrophasor data and then uses a neural network to identify the faulty buses. It is independent of network-specific data of the electrical power network. The proposed algorithm is evaluated using actual outage data from a real transmission system of Southwest Power Pool, in the year 2015. The results of the system implemented in python shows that the proposed method can detect fault locations with 100% accuracy.
Safflower Biodiesel: Improvement of its Oxidative Stability by Using BHA and TBHQ

Biodiesel is gaining more and more importance due to environmental issues. This way, alternative and sustainable crops as new biofuel sources are demanded. Safflower could be a sustainable raw material for biodiesel production, showing one disadvantage (as many biodiesels from vegetable oils), that is, a short oxidative stability. Consequently, the use of antioxidants to increase this parameter is mandatory. The aim of this research work was to assess the effect of two antioxidants (butylated hydroxyanisole, BHA, and tert-butylhydroquinone, TBHQ) on the oxidative stability of safflower biodiesel, which was characterized paying attention to its fatty acid methyl ester profile. For oxidative stability, the Rancimat method was used, whereas for fatty acid profile gas chromatography was selected. For the remaining parameters, the methods were followed according to the UNE-EN 14214 standard. The overall conclusion was that safflower biodiesel could comply with the standard, thanks to the use of antioxidants, with TBHQ being more effective than BHA. On the other hand, the combined use of these antioxidants did not show, especially at low concentrations, a synergic or additive effect, which makes the mixture of these antioxidants unsuitable to improve the oxidative stability.
Path Reconstruction in Dynamic Wireless Sensor Networks Using Compressive Sensing

This paper presents CSPR, a compressive-sensing-based approach for path reconstruction in wireless sensor networks. By viewing the whole network as a path representation space, an arbitrary routing path can be represented by a path vector in the space. As path length is usually much smaller than the network size, such path vectors are sparse, i.e., the majority of elements are zeros. By encoding sparse path representation into packets, the path vector and thus the represented routing path can be recovered from a small amount of packets using compressive sensing technique. CSPR formalizes the sparse path representation and enables accurate and efficient per-packet path reconstruction. CSPR is invulnerable to network dynamics and lossy links due to its distinct design. A set of optimization techniques is further proposed to improve the design. We evaluate CSPR in both testbed-based experiments and large-scale trace-driven simulations. Evaluation results show that CSPR achieves high path recovery accuracy i.e., 100% and 96% in experiments and simulations, respectively and outperforms the state-of-the-art approaches in various network settings.
A Categorical View on Algebraic Lattices in Formal Concept Analysis

Formal concept analysis has grown from a new branch of the mathematical field of lattice theory to a widely recognized tool in Computer Science and elsewhere. In order to fully benefit from this theory, we believe that it can be enriched with notions such as approximation by computation or representability. The latter are commonly studied in denotational semantics and domain theory and captured most prominently by the notion of algebraicity, e.g. of lattices. In this paper, we explore the notion of algebraicity in formal concept analysis from a category-theoretical perspective. To this end, we build on the notion of approximable concept with a suitable category and show that the latter is equivalent to the category of algebraic lattices. At the same time, the paper provides a relatively comprehensive account of the representation theory of algebraic lattices in the framework of Stone duality, relating well-known structures such as Scott information systems with further formalisms from logic, topology, domains and lattice theory.
Key variables for academic performance in university accounting studies. A mediation model

ABSTRACT This paper highlights the importance of conducting studies to ascertain students’ perceptions of the teaching-learning process, as this information can provide a valuable guide to course planning and enhance teaching. This study analyses, based on structural equation modelling, the relationship between students’ academic performance in an accounting course offered at the University of Granada and these students’ perceptions of aspects of the teaching-learning process. Results show that academic achievement is directly related, positively and significantly, to students’ prior interest in the course, their perceptions of the usefulness of the course, their level of class participation, their prior academic achievement and their age. Furthermore, we found that the prior interest of the students in the course is indirectly related to the final grade obtained, through the variables usefulness of the course and class participation. The implications of the results are discussed.
Altitude fails to increase susceptibility of ultramarathon runners to post-race upper respiratory tract infections

Reduced host resistance to infection following participation in an ultramarathon event, has been attributed to damage to the local mucosal membranes of the upper respiratory tract (URT). Physical properties of the mucous membranes have been reported to change and to result in impaired lymphocyte, neutrophil and macrophage function.
Continent‐Wide R1/R2 Current System and Ohmic Losses by Broad Dipolarization‐Injection Fronts

We employ Magnetospheric Multiscale, Geostationary Operational Environmental and Los Alamos National Laboratory satellites, as well as the ground magnetometer networks over Greenland and North America to study a substorm on 9 August 2016 between 9 and 10 UT. We found that during the substorm two earthward flows, whose dipolarization‐injection fronts exceeded 6.5 and 4 Earth's radii (RE) in YGSM, impinged and rebounded from Earth's dipolar field lines at L=6–7 downtail, where L is the McIlwain number. The impingements and rebounds ended with a substorm current system of downward R1 and upward R2 currents which grew to azimuthally cover the whole North American continent. At the fronts, regions of enhanced negative j·E′ were formed and peaked toward the end of the impingements. These regions appeared to be conjugate with eastward moving aurora (along the growth phase arc and together with eastward drifting energetic electrons at geosynchronous equatorial orbit), which manifests ionospheric Ohmic losses.
Effect of dietary inclusion of different lipid supplements on performance and carcass quality traits of growing beef heifers

The aim of this study was to evaluate the impact of dietary extruded flaxseed and/or rumen-protected lipids on growth performance and carcass quality of growing beef heifers. Sixty-three crossbreed heifers (Charolais X Limousine) were distributed into seven experimental groups, balanced in terms of age and live weight. Diets fed to the groups were isoproteic and differed in both, the dietary lipid source (extruded linseed and/or rumen-protected conjugated linoleic acid) and the supplementation length (90 or 180 days before slaughtering), having the same total amount of lipids and vitamin E, during their finishing period. The results obtained in the present study confirm that in low-protein diets, the inclusion of rumen-protected CLA, alone or in combination with flaxseed, did not bring any evident effect on feed intake, performance and carcass quality traits of growing beef heifers.
DEVELOPMENT OF PHYSICAL AND SELF-CONTROL ABILITIES OF JUNIOR SCHOOLCHILDREN (10–11 YEARS OLD)

Background. The goal of the research is to reveal the dynamics in physical abilities of junior school learners (10– 11 years old) and their links with development of self-control abilities by applying the programme for development of self-control abilities in physical education classes during the experimental period. The pedagogical experiment was carried out with 4th forms of general education schools of Klaipėda, Kaunas and Raseiniai from 2011 to 2012 and lasted for one school year. The research included 178 school learners in the experiment group (n = 85) and in the control group (n = 93). Methods. The questionnaire method was applied to evaluate the change in self-control abilities, whereas the testing method was used to identify the change in physical abilities (flexibility, explosive power, agility, speed, balance, abdominal muscle strength and stamina). Results. Statistically significant differences were identified among boys from the experimental and the control groups considering the results of flexibility, long jump, abdominal muscle strength and stamina (p < .01), dexterity and speed (p < .05) and among girls when measuring the results of flexibility, long jump, speed, balance, abdominal muscle strength and stamina (p < .01). Application of Pearson’s correlation, correlating links between the abilities of physical and psychosocial self-control, revealed that school learners with better abilities of psychosocial selfcontrol also demonstrated a number of better physical abilities: linear correlation links were established between psychosocial control and flexibility, explosive power, speed, stamina and balance abilities. These links showed that improvement of self-control skills had an effect on self-development of physical abilities. Conclusion. The research has revealed a positive impact of the programme due to which development of selfcontrol abilities determined a change in physical abilities.
End-to-end routing behavior in the Internet

The large-scale behavior of routing in the Internet has gone virtually without any formal study, the exception being Chinoy's analysis of the dynamics of Internet routing information [Ch93]. We report on an analysis of 40,000 end-to-end route measurements conducted using repeated "traceroutes" between 37 Internet sites. We analyze the routing behavior for pathological conditions, routing stability, and routing symmetry. For pathologies, we characterize the prevalence of routing loops, erroneous routing, infrastructure failures, and temporary outages. We find that the likelihood of encountering a major routing pathology more than doubled between the end of 1994 and the end of 1995, rising from 1.5% to 3.4%. For routing stability, we define two separate types of stability, "prevalence" meaning the overall likelihood that a particular route is encountered, and "persistence," the likelihood that a route remains unchanged over a long period of time. We find that Internet paths are heavily dominated by a single prevalent route, but that the time periods over which routes persist show wide variation, ranging from seconds up to days. About 2/3's of the Internet paths had routes persisting for either days or weeks. For routing symmetry, we look at the likelihood that a path through the Internet visits at least one different city in the two directions. At the end of 1995, this was the case half the time, and at least one different autonomous system was visited 30% of the time.
Adaptive Monitoring and Accommodation of Nonlinear Actuator Faults in Positive Real Infinite Dimensional Systems

We consider a class of positive real infinite dimensional systems which are subjected to incipient actuator faults. The actuator fault is modeled as a time varying transition from an initial (linear or even nonlinear) map into another unknown nonlinear map at the onset of the fault occurrence. An infinite dimensional adaptive detection observer is utilized to generate a residual signal in order to detect the fault occurrence and to assist in the fault accommodation. This is done via an automated control reconfiguration which utilizes information on the new actuator map and adjusts the controller via a right inverse of the new actuator map. A robust modification is utilized in order to avoid false alarms caused by unmodeled dynamics. An example is included to illustrate the applicability of the proposed detection scheme.
Evolution of divergence between the river lamprey (Lampetra fluviatilis) and the brook lamprey (L.planeri) inferred by experimental approaches and population genomics

This thesis investigates the process of speciation between the European lampreys Lampetra fluviatilis and L. planeri. The two species have drastically different life history strategies: L. fluviatilis is parasitic and anadromous while L. planeri is non-parasitic and strictly freshwater resident. Yet their level of reproductive isolation and history of divergence remain poorly understood. A multidisciplinary approach including experiments, population genomics analyses and historical reconstruction was undertaken to address these issues. Experimental crosses revealed a very low level of reproductive isolation, partially mirrored by variable levels of gene flow in wild populations. Genetic analyses revealed that the two taxa were best described as partially reproductively isolated ecotypes suggesting that endogenous genetic barriers partially reduced effective migration between ecotypes. Genome wide analyses showed the importance of the current and ancient geographical context of speciation. In particular, parapatric L. planeri populations diverged mostly through drift and displayed a reduced genetic diversity . Demographic inferences suggested that divergence have likely emerged in allopatry and then secondary contacts resulted in partial parallelism between replicate population pairs. A strong heterogeneity of divergence across the genome was revealed by sympatric populations suggesting that genomic islands of differentiation were not linked to ongoing ecological divergence. Further investigations showed that the genetic diversity of L. planeri populations was weakly affected by human-induced river fragmentation. Resident populations displayed a higher diversity when gene flow was possible with L. fluviatilis populations in downstream sections of rivers. Overall this thesis showed that parasitic and non-parasitic lamprey ecotypes represent a promising model for studying speciation and notably the genomic architecture of divergence.
