Feedback-based dead-time current clamp minimisation techniques

Current clamp is the term used to describe the phenomena of inverter controlled current staying at zero when the current crosses from positive to negative. Current clamp is a consequence of the inverter dead-time. If the current is feeding a machine, then dead-time causes torque pulsations, possible load resonances and extra losses in the machine. This paper considers some alternative feedback strategies that attempt to minimise current clamp when traditional PI current controllers are used.
The Effect of Dysfunctional Thought Processes on Subjective Well-Being and Job Satisfaction

While the dispositional approach to job satisfaction has received a good deal of recent attention, a fundamental deficiency in past dispositional research is a failure to use existing theories to explain why individuals are unhappy and dissatisfied with their jobs. Locke (1976), Judge (in press), and Judge and Hulin (in press) suggested that thinking processes should be studied in relation to job satisfaction. This study tested the thesis that the cognitive theory of depression, which focuses on irrational thought processes, will help in understanding both subjective well-being and job satisfaction. A causal model involving subjective well-being, job satisfaction, dysfunctional thought processes, and other relevant influences was hypothesized and tested using a stratified random sample of university employees. Ratings were obtained from two sources in order to reduce single-source bias. The results indicated strong support for the overall model and for the efficacy of dysfunctional thought processes.
Carbon and nitrogen economy of 24 wild species differing in relative growth rate.

The relation between interspecific variation in relative growth rate and carbon and nitrogen economy was investigated. Twentyfour wild species were grown in a growth chamber with a nonlimiting nutrient supply and growth, whole plant photosynthesis, shoot respiration, and root respiration were determined. No correlation was found between the relative growth rate of these species and their rate of photosynthesis expressed on a leaf area basis. There was a positive correlation, however, with the rate of photosynthesis expressed per unit leaf dry weight. Also the rates of shoot and root respiration per unit dry weight correlated positively with relative growth rate. Due to a higher ratio between leaf area and plant weight (leaf area ratio) fast growing species were able to fix relatively more carbon per unit plant weight and used proportionally less of the total amount of assimilates in respiration. Fast growing species had a higher total organic nitrogen concentration per unit plant weight, allocated more nitrogen to the leaves and had a higher photosynthetic nitrogen-use efficiency, i.e. a higher rate of photosynthesis per unit organic nitrogen in the leaves. Consequently, their nitrogen productivity, the growth rate per unit organic nitrogen in the plant and per day, was higher compared with that of slow growing species.
Poly (D,L-lactide-co-glycolide) nanoparticles: Uptake by epithelial cells and cytotoxicity

Nanoparticles as drug delivery systems offer benefits such as protection of the encapsulated drug against degra- dation, site-specific targeting and prolonged blood circulation times. The aim of this study was to investigate nanoparticle uptake into Caco-2 cell monolayers, their co-localization within the lysosomal compartment and their cytotoxicity in differ- ent cell lines. Rhodamine-6G labelled poly(D,L-lactide-co-glycolide) (PLGA) nanoparticles were prepared by a double emulsion solvent evaporation freeze-drying method. Uptake and co-localisation of PLGA nanoparticles in lysosomes were visualized by confocal laser scanning microscopy. The cytotoxicity of the nanoparticles was evaluated on different mam- malian cells lines by means of Trypan blue exclusion and the MTS assay. The PLGA nanoparticles accumulated in the inter- cellular spaces of Caco-2 cell monolayers, but were also taken up transcellularly into the Caco-2 cells and partially co-localized within the lysosomal compartment indicating involvement of endocytosis during uptake. PLGA nanoparticles did not show cytotoxic effects in all three cell lines. Intact PLGA nanoparticles are therefore capable of moving across epithelial cell membranes partly by means of endocytosis without causing cytotoxic effects.
Effect of Carbonized Saw Dust on the Mechanical Properties of Polyolefin Plastics

Carbonized particles of saw dust using maleic anhydride as coupling agent have been incorporated into high density polyethylene and polypropylene in the range of 10 – 50 wt % and injection moulded into rectangular sheets. The mechanical properties of the sheets were determined. The results obtained showed that certain properties (mechanical, bending strength as well as bending modulus and flexural) increased significantly in the narrow particle loading of range 0 -10 wt %.
Clinical utility of the Chinese Strengths and Weaknesses of ADHD-Symptoms and Normal-Behaviors questionnaire (SWAN) when compared with DISC-IV

Background Attention-deficit/hyperactivity disorder (ADHD) is a common and impairing child and adolescent psychiatric disorder. Early identification and prompt treatment are essential. Rating scales are commonly used by clinicians and researchers to assess ADHD children. Objective In the current study, we aimed to examine the clinical utility of the Chinese version of the Strengths and Weaknesses of ADHD Symptoms and Normal Behaviors (SWAN) questionnaire. We validated its subscale scores against the Diagnostic Interview Schedule for Children Version IV (DISC-IV) and looked into its ability to identify ADHD in a psychiatric clinic setting. We also tested age and gender effects on SWAN scores. Specific subscale cutoff scores of SWAN were subsequently determined. Method A total of 290 children aged 6–12 years old studying in local mainstream primary schools were recruited from a clinic setting and interviewed with the parent version of DISC-IV. Their parents and teachers completed the corresponding version of SWAN. Results Both parent and teacher versions of SWAN were found to have good concurrent validity with DISC-IV. It could identify ADHD well in a clinic sample. Gender-specific cutoff scores were determined. Sensitivities and specificities were found to be satisfactory. SWAN was also found to perform equally well in identifying ADHD in those with and without comorbid Autistic Spectrum Disorder. Conclusion SWAN was proven to be a useful tool to aid the assessment of ADHD in a clinic sample.
Dominant influenza A(H3N2) and B/Yamagata virus circulation in EU/EEA, 2016/17 and 2017/18 seasons, respectively

We use surveillance data to describe influenza A and B virus circulation over two consecutive seasons with excess all-cause mortality in Europe, especially in people aged 60 years and older. Influenza A(H3N2) virus dominated in 2016/17 and B/Yamagata in 2017/18. The latter season was prolonged with positivity rates above 50% among sentinel detections for at least 12 weeks. With a current west–east geographical spread, high influenza activity might still be expected in eastern Europe.
Making sense of social media streams through semantics: A survey

Using semantic technologies for mining and intelligent information access to social media is a challenging, emerging research area. Traditional search methods are no longer able to address the more complex information seeking behaviour in media streams, which has evolved towards sense making, learning, investigation, and social search. Unlike carefully authored news text and longer web context, social media streams pose a number of new challenges, due to their large-scale, short, noisy, contextdependent, and dynamic nature. This paper defines five key research questions in this new application area, examined through a survey of state-of-the-art approaches to mining semantics from social media streams; user, network, and behaviour modelling; and intelligent, semanticbased information access. The survey includes key methods not just from the Semantic Web research field, but also from the related areas of natural language processing and user modelling. In conclusion, key outstanding challenges are discussed and new directions for research are proposed.
Consequences of Intraspecific Competition and Environmental Variation for Selection in the Mustard Sinapsis arvensis: Contrasting Ecological and Evolutionary Perspectives

Alternative models of plant life‐history evolution differ in their views of how abiotic stress and competition interact to shape the evolution of plant life‐history traits. To address this debate, which crosses traditional boundaries between community ecology and population biology, we grew wild turnip families from three selection histories in a field experiment in which we manipulated conspecific density and sun exposure. Hot spring conditions caused neutral shading to reduce drought stress, resulting in a greater mean and variance for lifetime fertility at low density and greater intensity of competition at high density. The variance in relative fitness among individuals or families was least in partial shade at low density. Prior selection under shade stress in the greenhouse reduced lifetime fitness in the less stressful partial‐shade treatment under field conditions. Patterns of selection and predicted trait evolution were more similar between high and low densities than between the two light environments. Partial shade favored the proliferation of large leaves early in development, especially at high density. Selection in the stressful full‐sun treatment favored reduced pathogen susceptibility at both densities and early flowering at low density. Because direct selection on traits changed principally in magnitude rather than in direction, genetic correlations for fitness were generally positive between light and density treatments. Greater intraspecific competition led to more rapid predicted trait evolution in the partial‐shade environment but not in the stressful full‐sun treatment.
HSP90 Chaperoning in Addition to Phosphoprotein Required for Folding but Not for Supporting Enzymatic Activities of Measles and Nipah Virus L Polymerases

ABSTRACT Nonsegmented negative-stranded RNA viruses, or members of the order Mononegavirales, share a conserved gene order and the use of elaborate transcription and replication machinery made up of at least four molecular partners. These partners have coevolved with the acquisition of the permanent encapsidation of the entire genome by the nucleoprotein (N) and the use of this N-RNA complex as a template for the viral polymerase composed of the phosphoprotein (P) and the large enzymatic protein (L). Not only is P required for polymerase function, but it also stabilizes the L protein through an unknown underlying molecular mechanism. By using NVP-AUY922 and/or 17-dimethylaminoethylamino-17-demethoxygeldanamycin as specific inhibitors of cellular heat shock protein 90 (HSP90), we found that efficient chaperoning of L by HSP90 requires P in the measles, Nipah, and vesicular stomatitis viruses. While the production of P remains unchanged in the presence of HSP90 inhibitors, the production of soluble and functional L requires both P and HSP90 activity. Measles virus P can bind the N terminus of L in the absence of HSP90 activity. Both HSP90 and P are required for the folding of L, as evidenced by a luciferase reporter insert fused within measles virus L. HSP90 acts as a true chaperon; its activity is transient and dispensable for the activity of measles and Nipah virus polymerases of virion origin. That the cellular chaperoning of a viral polymerase into a soluble functional enzyme requires the assistance of another viral protein constitutes a new paradigm that seems to be conserved within the Mononegavirales order. IMPORTANCE Viruses are obligate intracellular parasites that require a cellular environment for their replication. Some viruses particularly depend on the cellular chaperoning apparatus. We report here that for measles virus, successful chaperoning of the viral L polymerase mediated by heat shock protein 90 (HSP90) requires the presence of the viral phosphoprotein (P). Indeed, while P protein binds to the N terminus of L independently of HSP90 activity, both HSP90 and P are required to produce stable, soluble, folded, and functional L proteins. Once formed, the mature P+L complex no longer requires HSP90 to exert its polymerase functions. Such a new paradigm for the maturation of a viral polymerase appears to be conserved in several members of the Mononegavirales order, including the Nipah and vesicular stomatitis viruses.
A biogeographic perspective on the evolution of fire syndromes in pine trees (Pinus: Pinaceae)

Our goals were to explore the relationship between biogeography and the evolution of fire-adaptive syndromes in the genus Pinus. We used a previously published time-calibrated phylogeny and conducted ancestral trait reconstruction to estimate the likely timing of diversification in Pinus, and to determine when fire-adaptive syndromes evolved in the lineage. To explore trait conservation among fire syndromes and to investigate historical biogeography, we constructed ancestral state reconstructions using the program RASP and estimated the degree of conservatism for fire-adapted traits in the program BaTS. Our reconstructions suggest that the Bering land bridge, which connected North America and Asia, probably played a major role in early pine evolution. Our estimates indicated that fire-adaptive syndromes seem to have evolved more frequently in New World taxa and probably are related to the uplift of major North American mountain ranges. Our data suggest that certain geographically widespread adaptations to fire evolved repeatedly, possibly due to localized changes in climate and environment, rather than resulting from large dispersal events of pre-adapted individuals.
Optimal Exact Path-Following for Constrained Differentially Flat Systems

We propose a dynamic optimization approach to calculate optimal feedforward controls for exact path-following problems of differentially flat systems. Besides the derivation of a small dimensional optimal control problem, we provide easily checkable conditions on the existence of inputs guaranteeing that a given path is exactly followable in the presence of constraints on states and inputs. Our approach is based on the projection of the feedforward controlled, nonlinear MIMO dynamics along a geometric path onto a linear single-input system in Brunovsky normal form. The presented results indicate how the computation of admissible trajectories for set-point changes can be simplified by relying on steady state consistent paths. The set-point change of a Van de Vusse reactor is considered as an example.
Getting to ‘know’ connectors? Evaluating data-driven learning in a writing skills course

This paper sets out to evaluate the effect on learners’ knowledge and use of language of one prominent technique in corpus pedagogy, the data-driven use of corpus concordances with learners as researchers, or Data-Driven Learning (DDL) (Johns 1988, 1991). More specifically, the paper attempts measurement of the effect of DDL on the achievement of the goal of appropriate production by learners of logical connectors, an important subskill in the context of the wider objective of the acquisition of basic academic writing skills in English. The evaluation uses learner corpora from experimental and control groups, supported by other methods. The conclusion is that DDL, applied in the context of the communicative teaching of writing skills, is moderately effective, and that there is potential both for the further development of learner corpora in an evaluative role, and for use of a wider range of instrumentation.
Comparison of Special Sensor Microwave Imager and buoy‐measured wind speeds from 1987 to 1997

We compare wind speeds derived from microwave radiometer measurements made by the Special Sensor Microwave Imager (SSM/I) series of satellite instruments to those directly measured by buoy-mounted anemometers. The mean difference between SSM/I and buoy winds is typically , 0.4 ms 21 when averaged over all operational Tropical Atmosphere-Ocean and National Data Buoy Center buoys for a given year, and the standard deviation is , 1.4 ms 21 . Mean errors for a given satellite-buoy pair typically range from 2 1t o1 1ms 21 , with standard deviations , 1.4 ms 21 . Two methods of converting buoy-measured wind speed to a standard value measured at a height of 10 m are compared. We find that the principal difference between a simple logarithmic correction and a more detailed conversion to 10 m equivalent neutral stability wind speed is a shift of wind speed by about 0.12 m s 21 with no change in the distribution of SSM/I- buoy wind speed differences.
Employee readiness for acceptance of decision support systems as a new technology in E-business environments; A proposed research agenda

This paper proposes a methodology for application of a conceptual model developed as part of an ongoing doctoral research in a previous paper to investigate the effects of employees' readiness for E-business on technology acceptance with respect to use of a new technology, a state of the art support software helping integrate functions across multiple departments which in turn would be helpful for an improved data-driven decision-making by managers. The proposed research model is based on the empirical study on employee readiness for E-business (EREB) by Lai & Ong and Davis' technology acceptance model (TAM). The data for this study shall be collected from employees of British tourism firms operating additional back-end support offices abroad. The results of the study are expected to show that EREB model has an influence on perceived ease of use and perceived usefulness leading to actual use of technology.
Supervised Deep Polylingual Topic Modeling for Scholarly Information Recommendations

Polylingual text processing is important for content-based and hybrid recommender systems. It helps recommender systems extract content information from broader sources. It also enables systems to recommend items in a user’s native language. We propose a cross-lingual keyword recommendation method based on a polylingual topic model. The model is further extended with a popular deep learning architecture, the CNN– RNN model. With this model, keywords can be recommended from text written in different languages; model parameters are very meaningful, and we can interpret them. We evaluate the proposed method using crosslingual bibliographic databases that contain both English and Japanese abstracts and keywords.
Localization of Quaternary slip rates in an active rift in 105 years: An example from central Greece constrained by 234U‐230Th coral dates from uplifted paleoshorelines

Mapping, dating, and modeling of paleoshorelines uplifted in the footwall of the 1981 Gulf of Corinth earthquake fault, Greece (Ms 6.9–6.7), are used to assess its slip rate history relative to other normal faults in the area and study strain localization. The 234U-230Th coral ages from Cladocora caespitosa date uplifted shoreface sediments, and paleoshorelines from glacioeustatic sea level highstands at 76, (possibly) 100, 125, 175, 200, 216, 240, and 340 ka. Uplifted Quaternary and Holocene paleoshorelines decrease in elevation toward the western tip of the fault, exhibiting larger tilt angles with age, showing that uplift is due to progressive fault slip. Since 125 ka, uplift rates varied from 0.25 to 0.52 mm/yr over a distance of 5 km away from the fault tip. Tilting was also occurring prior to 125 ka, but uplift rates were lower because the 125 ka paleoshoreline is at 77% of the elevation of the 240 ka paleoshoreline despite being nearly half its age. Comparison of paleoshoreline elevations and sedimentology with the Quaternary sea level curve shows that slip rates increased by a factor of 3.2 ± 0.2 at 175 ± 75 ka, synchronous with cessation of activity on a neighboring normal fault at 382–112 ka. We suggest that the rapid localization of up to 10–15 mm/yr of extension into the narrow gulf (∼30 km wide) resulted from synchronous fault activity on neighboring faults followed by localization rather than sequential faulting, with consequences for the mechanism controlling localization of extension.
Film Casting of a Low Density Polyethylene Melt

Film casting is one of the major commercial film manufacturing processes. Although various investigators have studied the process, no comprehensive set of data is available. In this study, film casting experiments of a LDPE polymer melt are conducted. The rheological properties of the melt, the film tension, the velocity profile, and the film width profile due to necking in will be presented. The thickness profile of the solidified film and the edge bead profile will also be reported. These experimental data will be useful for process analysis and verification of film casting simulation.
Bacterial Study of CSOM and their Changing Patterns of Antibiotic Sensitivity and Resistance

Chronic serous Otitis Media is not the same as Chronic Suppurative Otitis Media. The former may be defined as a middle ear effusion, without perforation, persisting for more than 1-3 months (Charles, 2006). Chronic Suppurative Otitis Media is characterized by drainage from the middle ear for at least two weeks and is associated International Journal of Current Microbiology and Applied Sciences ISSN: 2319-7706 Volume 5 Number 10 (2016) pp. 282-288 Journal homepage: http://www.ijcmas. com
Resistance to Carbapenems in Non-Typhoidal Salmonella enterica Serovars from Humans, Animals and Food

Non-typhoidal serovars of Salmonella enterica (NTS) are a leading cause of food-borne disease in animals and humans worldwide. Like other zoonotic bacteria, NTS have the potential to act as reservoirs and vehicles for the transmission of antimicrobial drug resistance in different settings. Of particular concern is the resistance to critical “last resort” antimicrobials, such as carbapenems. In contrast to other Enterobacteriaceae (e.g., Klebsiella pneumoniae, Escherichia coli, and Enterobacter, which are major nosocomial pathogens affecting debilitated and immunocompromised patients), carbapenem resistance is still very rare in NTS. Nevertheless, it has already been detected in isolates recovered from humans, companion animals, livestock, wild animals, and food. Five carbapenemases with major clinical importance—namely KPC (Klebsiella pneumoniae carbapenemase) (class A), IMP (imipenemase), NDM (New Delhi metallo-β-lactamase), VIM (Verona integron-encoded metallo-β-lactamase) (class B), and OXA-48 (oxacillinase, class D)—have been reported in NTS. Carbapenem resistance due to the production of extended spectrum- or AmpC β-lactamases combined with porin loss has also been detected in NTS. Horizontal gene transfer of carbapenemase-encoding genes (which are frequently located on self-transferable plasmids), together with co- and cross-selective adaptations, could have been involved in the development of carbapenem resistance by NTS. Once acquired by a zoonotic bacterium, resistance can be transmitted from humans to animals and from animals to humans through the food chain. Continuous surveillance of resistance to these “last resort” antibiotics is required to establish possible links between reservoirs and to limit the bidirectional transfer of the encoding genes between S. enterica and other commensal or pathogenic bacteria.
