A Modular Multi-level Converter (M2LC) based on Inductive Power Transfer (IPT) technology

This paper proposes a new Modular Multi-level Converter (M2LC) topology, which is based on an Inductive Power Transfer (IPT) technology. The modified M2LC topology employs an IPT system to control the capacitor voltage of each module, thereby decoupling the capacitor voltage balancing control from the load current control. The IPT system maintains the capacitor voltages within a narrow band around a nominal value, simplifies the control algorithm and offers new advantages, such as operation at low output frequency, implementation of simple control schemes and reduced energy requirements over the existing topology. The concept is validated using simulations for a single-phase three-level M2LC and compared with the existing topology to demonstrate the performance improvements associated with the modified topology.

The self-injection-locked narrow linewidth DBR laser can be tuned by 13 nm, covering 18 channels, with side mode suppression ratios over 38 dB and linewidths all <;10 kHz.
Enhancing clinical implementation of virtual reality

Despite an emerging evidence base and rapid increases in the development of clinically accessible virtual reality (VR) technologies for rehabilitation, clinical adoption remains low. This paper uses the Theoretical Domains Framework to structure an overview of the known barriers and facilitators to clinical uptake of VR and discusses knowledge translation strategies that have been identified or used to target these factors to facilitate adoption. Based on this discussion, we issue a ‘call to action’ to address identified gaps by providing actionable recommendations for development, research and clinical implementation.
3D Recognition and Pose Estimation Using Model Reconstructed by Pairwise Correspondence

This paper focuses on pose estimation of 3D object from 2D images. The base system of Structure from Motion is applied. A 3D model with feature points and descriptors is prebuilt. 3D-2D matching is employed in recognition and pose estimation process. The method of pairwise correspondence is proposed. To reduce reprojection error of the model, a weighting step is added. Viewpoint change of camera is simulated by affine transformation in 3D model description. Simulated affine feature is modified to keep the model compact. In experiment section, the performance of the pose estimation system as well as the modified affine feature are tested, and the results are compared to related previous research.
MICROWAVING LOGS FOR ENERGY SAVINGS AND IMPROVED PAPER PROPERTIES FOR MECHANICAL PULPS

High-power microwave cooking of commercial black spruce pulpwood logs was investigated as a pretreatment for mechanical pulping. Several dozen logs were treated at a variety of power levels (10 to 50 kW) and for various times (1 to 10 min). The mechanical pulping trials resulted in significant energy savings -up t o 15% for the highest power level. In addition, there was a corresponding increase in handsheet properties (+35% burst index, +20% tear index, and +13% tensile index) and a modest reduction in brightness (-10%). Handsheets were made to simulate a lightweight coated furnish, and microwave-treated thennomechanical pulp was used to supplement a reduction in the kraft component. Based on handsheet properties, as much as 10% kraft pulp could be substituted with only slight reductions in strength. Annual pulp cost savings were estimated for an 800 ton/day pulp mill based on anticipated kraft substitution levels, refiner energy savings, and microwave pretreatment costs. We altering the softening the Subsequent and would occur more and fiber damage would be reduced. The following report describes an exploratory investigation of the effects of microwave pretreatment on the mechanical pulping characteristics of commercial black spruce logs.
Rolling Circle Amplification on Biotin-Streptavidin Complexes Immobilized to Activated Cyclic Polyolefin Surfaces

Cyclic polyolefin (COP) is an inexpensive hydrophobic material with low auto-fluorescence, high light transmittance and thermal stability, broad chemical resistance and no non-specific protein binding. Here, the hydrophobic alkane COP was modified to have carbonyl functionalities through oxygen plasma and chemical etching treatments to increase usefulness for chemical and biochemical applications. Then, biotin-hydrazide was used to create biotinylated surfaces that bound streptavidin. A biotinylated target oligonucleotide was subsequently bound to the immobilized biotin-streptavidin and ligation mediated rolling circle amplification-based (L-RCA) SNP detection was demonstrated.
An FSS Structure Based on Parallel LC Resonators for Multiband Applications

An frequency selective surface (FSS) structure based on parallel LC resonators is proposed to achieve multiband bandpass filtering responses. The parallel LC resonator, implemented by a via-connected metallic line and a parallel-plate capacitor (PPC), serves as the basic element for intentionally constructing FSS unit cell, which exhibits a single-band bandpass filtering response. As a result, the proposed FSS structure can provide a multiband performance by introducing multiple VCMLs and PPCs with different resonance frequencies. Because of the compact resonator resulting from a PPC, the proposed FSSs feature miniaturized unit cell size inherently, for example, the single-band FSS element is as compact as 4.8% of the operating wavelength. Moreover, this kind of FSS structure is also beneficial for independent control of the frequency performance under different polarizations, efficient optimal design of desired resonance frequencies, and easy realization of multiband response with wideband ratio range (e.g., 1.13 to 3.32 for the dual-band FSS). Equivalent circuits of these FSSs are established for explaining the resonating mechanisms and precisely modeling the frequency performances. Finally, prototypes of the dual- and tri-band FSSs are fabricated and measured. The measured results exhibit stable filtering performance under different polarizations and incidence angles (up to 60°).
NEW STRATEGIES IN LIVER SURGERY FOR IV STAGE METASTATIC COLORECTAL CANCER

With recent advances in chemotherapy, traditional clinicopathological factors should not be used to exclude otherwise resectable patients from surgery. Pathological or clinical response to chemotherapy has become valuable in determining the treatment for individual patients. Portal vein embolization and two-stage operation with ablative therapy and preoperative chemotherapy should be considered for unresectable liver metastases located in a liver remnant that is at the minimum volume required for survival. The recent E0RTC 40983 trials regarding preoperative chemotherapy for resectable CLM have failed to demonstrate a clear significant advantage. However, patients with a low clinical risk score for the recurrence, such as several metastases of less than 4 cm, and who are fit candidates for liver resection are often offered immediate surgery. Patients at high clinical risk should also be considered for neoadjuvant chemotherapy. One forthcoming and appealing strategy is to adapt postoperative treatment according to tumor response as evaluated by neoadjuvant chemotherapy or by the presence of individual tumor biomarker such as the Kras mutation or singlenucleotide polymorphisms. This could avoid the overtreatment of nonresponsive patients and enable a more tailored approach to treat an individual patient’s disease. The treatment paradigm for CLM is rapidly changing with the development of newer anticancer chemotherapeutic agents.
Modeling of Five-Level Converter Used in a Synchronous Rectifier Application

In this paper it is presented a modeling process of a five-level neutral point clamped converter used in a synchronous rectifier application and the resulting model that describes the dynamics for such converter. The highly nonlinear model, originally in abc-coordinates, is also expressed in its alphabetagamma-coordinates. Special attention is given to the gamma-component of the control input, which represents a degree of freedom that can be used for the balancing of the capacitors voltages. It is shown that the sum of capacitors voltages is a natural state of the system since it is necessary to control the total voltage on the DC side and, indeed, it reduce considerably the model expression which describes the dynamics of that voltage. It is also shown that the controller gamma-component has a minimum influence on the sum of the capacitors voltages, but it has a strong influence on the difference, hence its importance in the capacitors voltages balance. Simulations are presented to validate the proposed model. This new modeling approach and resulting model it is expected to stimulate new control proposals in the future
Effect of the audio amplifier's distortion on feedforward active noise control

Active noise control (ANC) is an effective method for reducing low-frequency acoustic noise. An anti-noise wave is transmitted by the secondary source to destructively interfere with the noise wave. A quiet zone is thus formed around the error microphone, which provides the error signal in the adaptation process of an ANC controller. However, the real-world performance of an ANC system is often subjected to the distortion incurred in its electronic components. This distortion has been conventionally treated as a trivial part of the secondary path model. When the distortion is severe but the secondary path model is still forced to be linear, the nonlinearity of the true secondary path is no longer negligible and causes degradation in noise reduction performance or even divergence of the ANC controller. This paper revisits the causes of the amplitude distortion in the audio amplifier and how it influences the convergence of the filtered-x least mean square (FxLMS) algorithm in a feedforward ANC system for tonal noise cancellation.
Triticum aestivum L . exposed to chromium stress

Wheat (Triticum aestivum L. cv. Sonalika) seedlings were grown in presence of K 2 Cr 2 O 7 (10, 50 and 100 ppm) for 7 days and growth, total chlorophyll, activities of antioxidative enzymes like superoxide dismutase (SOD; EC 1.15.1.1), catalase (CAT; EC 1.11.1.6) and guaiacol peroxidase (POX; EC 1.11.1.7) and lipid peroxidation were determined in root and shoot tissues. Growth of the seedlings was significantly (p < 0.05) depressed and at 100 ppm, root length was reduced by 63% and shoot length by 44% in comparison to the respective controls. Total chlorophyll loss in shoots was about 46% at 10 ppm of K 2 Cr 2 O 7 which further increased to 80% at 100 ppm. Both in root and shoot tissues, activities of SOD and CAT declined with increase of metal in growth medium and it was significant (p < 0.05) even at lowest concentration of the metal tested. But POX activity showed a different trend. In root tissues it was decreased whereas in shoots, there was many fold increase in the activity (about 370% over control at 100 ppm). Malondialdehyde (MDA) content increased both in root and shoot tissues, but it reached significant (p < 0.05) level at 50 ppm in roots and at 100 ppm in shoot tissues. Even though antioxidative enzyme activities were not assayed in germinating embryos, inhibition in germination percentage (by 40% at 100 ppm) and increase in lipid peroxidation level (by 71% over control at 100 ppm) were observed in 2-day-old embryos, germinated in presence of K 2 Cr 2 O 7 (10, 50 and 100 ppm). The results indicated the imposition of oxidative stress situations both during germination and early stages of seedling growth by Cr 6 stress, which might be one of the probable reasons behind Cr toxicity in plants.
HYPO-OSMOTIC SWELLING TEST ON BUFFALO (Bubalus bubalis) SEMEN

T he experiment was conducted in semen of Murrah buffalo bulls. The semen was exposed to three different concentrations of hypo-osmotic solution (150, 100 and 75 milliosmole) at different time periods at 37 o C. At 100 mOsm there was highly signifi cant (p< 0.01) difference at 45 and 60 minutes between different bulls. It was concluded that 100 mOsm concentration of hypo-osmotic solution was suitable for semen evaluation in buffalo species.
Crenarchaeota and Euryarchaeota in temperate estuarine sediments

Aims: Application of molecular techniques to ecological studies has unveiled a wide diversity of micro‐organisms in natural communities, previously unknown to microbial ecologists. New lineages of Archaea were retrieved from several non‐extreme environments, showing that these micro‐organisms are present in a large variety of ecosystems. The aim was therefore to assess the presence and diversity of Archaea in the sediments of the river Douro estuary (Portugal), relating the results obtained to ecological data.
Analysing Finnish with word lists Voutilainen , Atro

Morphological lexicons for morphologically complex languages provide good text coverage at the cost of overgeneration, difficulty of modification, and sometimes performance issues. Use of simple, manageable lexicon forms – especially lists – for morphologically complex languages may appear unviable because the number of possible word-forms in a morphologically complex language can be prohibitively high. We created and experimented with a list-based lexicon for a morphologically complex language (Finnish), and compared its coverage with that of a mature morphological analyser on new text in two experimental settings. e observed smallish difference in coverage suggests the viability of using simple and easy-to-modify list-based lexicons as an initial part of morphological analysis, to increase developer control on the vast majority of input tokens.

Device model for the operation of polymer/fullerene bulk heterojunction solar cells

We have developed a numerical device model that consistently describes the current-voltage characteristics of polymer:fullerene bulk heterojunction solar cells. Bimolecular recombination and a temperature- and field-dependent generation mechanism of free charges are incorporated. It is demonstrated that in poly[2-methoxy-5-(3('),7(')-dimethyloctyloxy)-p-phenylene vinylene]- (OC1C10-PPV-) and [6,6]-phenyl C-61-butyric acid methyl ester- (PCBM-) (1:4 wt. %) based solar cells space-charge effects only play a minor role, leading to a relatively constant electric field in the device. Furthermore, at short-circuit conditions only 7% of all free carriers are lost due to bimolecular recombination. The model predicts that an increased hole mobility together with a reduction of the acceptor strength of 0.5 eV will lead to a maximum attainable efficiency of 5.5% in the PPV/PCBM-based solar cells.
Desperately Seeking Information in Information Systems Research Research-in-Progress

The information systems (IS) research community has long engaged in dialogue as to the core of IS and the discipline’s legitimacy within business schools. Our concern is that efforts to protect the discipline by theorizing the IT artifact may have diverted attention from conceptualizing information as the dependent variable, through which we assess the effectiveness of our true core subject matter—information systems. To evaluate this supposition, this study employs a text-mining software, Leximancer v.4, to analyze the content of editorials published in AIS “basket of six” journals between 2002 and 2014. Preliminary results hint at subtle changes in themes, as well as the meaning and relevance of “information” over time. Once analysis is complete, we will draw on the findings to suggest potential opportunities and directions for IS research that treat information (the end) as seriously as its means (the IT artifact).
Mediated Moderation or Moderated Mediation: Relationship between Length of Unemployment, Resilience, Coping and Health

The aim of the present research was to evaluate a model of mediated moderation vs. moderated mediation that could explain the relationship between length of unemployment, dispositional resilience, coping styles and depression and social functioning of Venezuelan unemployed individuals. Self-report measures were administered to a sample of 328 unemployed residents in Caracas, Venezuela. Results indicated that emotional coping acted as a mediator in the relationship between resilience and depression. Individuals with greater resilience used more detachment coping when unemployment was longer, while individuals with poorer resilience in the same situation used less avoidance coping. Resilience acted as a protective moderating factor between longer periods of unemployment and social functioning, a process mediated by detachment coping. Overall, results supported a mediated moderation model, with resilience as the moderating factor and coping as the mediator in the relation between stress due to the length of unemployment and well-being. El objetivo de la presente investigación fue evaluar un modelo de moderación mediada vs. mediación moderada que permitiera explicar la relación entre la duración del desempleo, una medida disposicional de resiliencia, los estilos de afrontamiento y la depresión y el funcionamiento social percibido en desempleados venezolanos. Para ello se administraron instrumentos de auto-informe a una muestra de 328 desempleados residentes en la ciudad de Caracas, Venezuela. Los resultados indicaron que el afrontamiento emocional operó como un factor mediador en la relación entre la resiliencia y la depresión. Asimismo, las personas más resilientes usan más el afrontamiento por desapego cuando tienen más tiempo desempleadas, mientras que las personas menos resilientes en esa misma condición hacen menos afrontamiento evitativo. La resiliencia operó como factor moderador del impacto de la duración del desempleo sobre el funcionamiento social, actuando como un factor protector, proceso que estuvo mediado por el afrontamiento por desapego emocional. En síntesis, los resultados apoyan un modelo de moderación mediada, siendo la resiliencia el factor moderador y el afrontamiento el factor mediador en el impacto del estrés por la duración del desempleado sobre la salud.
A tunable bandpass patch filter with varactors

This paper presents a miniaturized tunable bandpass patch filter using varactors. The filter is conceived with a triple-mode circular patch resonator with four slots, where the varactors were connected. The extracted equivalent model, the varactors assembly configuration and their biasing are presented. A DC bias from 0 to 20 V was applied to vary the filter's center frequency from 2.35 GHz to 1.8 GHz and its 3-dB fractional bandwidth from 31.5% to 8.5%. Within these variations, all measurements showed insertion loss lower than 2 dB and return loss better than 10 dB over the passband, ensuring a good quality factor.
Sarcoplasmic reticulum Ca2+‐induced Ca2+ release regulates class IIa HDAC localization in mouse embryonic cardiomyocytes

In embryonic cardiomyocytes, sarcoplasmic reticulum (SR)‐derived Ca2+ release is required to induce Ca2+ oscillations for contraction and to control cardiac development through Ca2+‐activated pathways. Here, our aim was to study how SR Ca2+ release regulates cytosolic and nuclear Ca2+ distribution and the subsequent effects on the Ca2+‐dependent localization of class IIa histone deacetylases (HDAC) and cardiac‐specific gene expression in embryonic cardiomyocytes. Confocal microscopy was used to study changes in Ca2+‐distribution and localization of immunolabeled HDAC4 and HDAC5 upon changes in SR Ca2+ release in mouse embryonic cardiomyocytes. Dynamics of translocation were also observed with a confocal microscope, using HDAC5‐green fluorescent protein transfected myocytes. Expression of class IIa HDACs in differentiating myocytes and changes in cardiac‐specific gene expression were studied using real‐time quantitative PCR. Inhibition of SR Ca2+ release caused a significant decrease in intranuclear Ca2+ concentration, a rapid nuclear import of HDAC5 and subnuclear redistribution of HDAC4. Endogenous localization of HDAC5 and HDAC4 was mostly cytosolic and at the nuclear periphery, respectively. Downregulated expression of cardiac‐specific genes was also observed upon SR Ca2+ release inhibition. Electrical stimulation of sarcolemmal Ca2+ influx was not sufficient to rescue either the HDAC localization or the gene expression changes. SR Ca2+ release controls subcellular Ca2+ distribution and regulates localization of HDAC4 and HDAC5 in embryonic cardiomyocytes. Changes in SR Ca2+ release also caused changes in expression of the developmental phase‐specific genes, which may be due to the changes in HDAC‐localization.
Pareto – optimal model output correction model selection Pareto – optimal model output correction model selection

Ideas from the field of mathematical optimization will be employed in order to gain a new view on model output correction. We will compare several kinds of models with regard to their performance considering model output correction multidimensionally. Decision problems we were confronted with will be discussed, as well as the quality and shortcomings of the models our research resulted in. We will point out in what direction future research might head and what behavior is to be considered bad when it comes to model output correction modeling. Furthermore, we will point out, that one metric of model performance performs poorly with respect to our problem.
THE TRANSCENDENTAL MEDITATION TECHNIQUE , WORKING MEMORY , AND FIELD INDEPENDENCE IN SCHOOL-AGED CHILDREN

The effect of the Transcendental Meditation (TM) technique on working memory and field independence was investigated in a twelve-week longitudinal time-series study in which the uMatch Me" computerized memory game and the Rod and Frame Test were administered daily to a matched pair of 11-year-old boys and a matched pair of 14-year-old girls. One of the boys and one of the girls began the TM technique after six weeks. The data were analyzed by factorial ANOVAs, which were appropriate because of absence of time-series autocorrelations or correlations between factors. The predicted improvement among experimental subjects in contrast to controls was found for the memory task and, for the younger male subjects, on the field independence measure. Experimental and control older female subjects both increased in field independence as a result of repeated measurement.
