A new control strategy combing PI and quasi-PR control under rotate frame for three phase grid-connected photovoltaic inverter

In this paper, a new control strategy that combines Proportion Integrity (PI) with quasi-Proportion Resonant (PR) control under d-q rotate frame is proposed for three phase grid-connected photovoltaic inverter to achieve the zero error tracking of fundamental current as well as to suppress the selected harmonics current. Also, grid voltage feed forward is used to enhance the dynamic response and disturbance rejection capability. Finally, the proposed strategy is implemented on a 100 kW PV array grid-connected inverter with 1.21% THD of grid current at 80kW output and 7th harmonics reduced by more than half. The experimental result shows that the proposed control strategy has good performance in fundamental current tracking and harmonics current rejection.
Low loss double-layer substrate integrated waveguide-hybrid branch line coupler for mm-wave antenna arrays

This paper presents a novel double-layer hybrid branch line coupler (HBLC) design for millimeter-wave (mm-wave) antenna array applications. It is based upon the substrate integrated waveguide (SIW) technique, which is considered to be a low loss and low cost technology. The full-wave solver, HFSS, is used to simulate and optimize the proposed SIW-HBLC for minimum loss performance. The simulated results of the compact design are compared to these of the original (single layer) design presented in the literature. The SIW-HBLC shows a maximum −0.8 dB loss within an operating frequency band of 600 MHz around the center frequency 34.89 GHz.
Structural features of the TatC membrane protein that determine docking and insertion of a twin-arginine signal peptide

Twin-arginine translocation (Tat) systems transport folded proteins across cellular membranes with the concerted action of mostly three membrane proteins: TatA, TatB, and TatC. Hetero-oligomers of TatB and TatC form circular substrate–receptor complexes with a central binding cavity for twin-arginine–containing signal peptides. After binding of the substrate, energy from an electro-chemical proton gradient is transduced into the recruitment of TatA oligomers and into the actual translocation event. We previously reported that Tat-dependent protein translocation into membrane vesicles of Escherichia coli is blocked by the compound N,N′-dicyclohexylcarbodiimide (DCCD, DCC). We have now identified a highly conserved glutamate residue in the transmembrane region of E. coli TatC, which when modified by DCCD interferes with the deep insertion of a Tat signal peptide into the TatBC receptor complex. Our findings are consistent with a hydrophobic binding cavity formed by TatB and TatC inside the lipid bilayer. Moreover, we found that DCCD mediates discrete intramolecular cross-links of E. coli TatC involving both its N- and C-tails. These results confirm the close proximity of two distant sequence sections of TatC proposed to concertedly function as the primary docking site for twin-arginine signal peptides.
The membrane‐bound bile acid receptor TGR5 is localized in the epithelium of human gallbladders

TGR5 (Gpbar‐1) is a plasma membrane‐bound, G protein–coupled receptor for bile acids. TGR5 messenger RNA (mRNA) has been detected in many tissues, including rat cholangiocytes and mouse gallbladder. A role for TGR5 in gallstone formation has been suggested, because TGR5 knockout mice did not develop gallstones when fed a lithogenic diet. In this study, expression and localization of TGR5 was studied in human gallbladders. TGR5 mRNA and protein were detected in all 19 gallbladders. Although TGR5 mRNA was significantly elevated in the presence of gallstones, no such relation was found for TGR5 protein levels. In order to study the localization of TGR5 in human gallbladders, a novel antibody was generated. The receptor was localized in the apical membrane and the rab11‐positive recycling endosome of gallbladder epithelial cells. Furthermore, the TGR5 staining colocalized with the cyclic adenosine monophosphate–regulated chloride channel cystic fibrosis transmembrane conductance regulator (CFTR) and the apical sodium‐dependent bile salt uptake transporter, suggesting a functional coupling of TGR5 to bile acid uptake and chloride secretion. Stimulation with bile acids significantly increased cyclic adenosine monophosphate concentration in human gallbladder tissue. Incubation of gallbladder epithelial cells with a TGR5 agonist led to a rise of N‐(ethoxycarbonylmethyl)‐6‐methoxyquinolinium bromide (MQAE)‐fluorescence, suggestive of a decrease in intracellular chloride concentration. The TGR5 agonist–dependent increase in MQAE‐fluorescence was absent in TGR5 knockout mice or in the presence of a CFTR inhibitor, indicating that TGR5 mediates chloride secretion via activation of CFTR. The presence of the receptor in both the plasma membrane and the recycling endosome indicate that TGR5 can be regulated by translocation. Conclusion: The data suggest a role for TGR5 in bile acid–induced fluid secretion in biliary epithelial cells. (HEPATOLOGY 2009.)
The Role of Information Behaviors and Values in Strategic Information Systems Utilization : an investigation in the Business Intelligence Systems context

Although the constituents of information systems success and their relationships have been well documented in the business value of information technology literature, our understanding of how information behaviors and values affect the relationships among strategic information systems success dimensions is limited. In response, we conduct a quantitative study of 146 medium and large firms that have implemented a business intelligence system in their operations. Our results highlight that information sharing values, information informality, and information proactiveness act as significant moderators of information systems success relationships amidst volitional environment.
Bird Calls: Their Potential for Behavioral Neurobiology

Abstract: Birdsongs are always part of larger set of sound signals. Every bird uses a repertoire of calls for communication. Calls are shorter and simpler than songs, with a much larger range of functions. Whereas songs are specialized for application in reproduction and territoriality, calls also serve such functions as signaling about food, maintaining social cohesion, contact calls, synchronizing and coordinating flight, and the resolution of aggressive and sexual conflicts. Alarm calls of various kinds are a major component, including distress, mobbing, and hawk alarm calls. Call repertoires vary greatly in size, up to 20 or so distinct call types. Rough estimates for songbirds range between 5 and 10, but some birds, especially galliforms, may have twice as many. Call usage is often sexually dimorphic and commonly varies seasonally and with physiological state. Most calls appear to be innate, but more and more examples of developmental plasticity in bird calls are emerging. Some display well‐defined local dialects. A case is made for the value to avian behavioral neurobiology of including bird calls in studies of the psychophysics and sensory physiology of signal perception. They may also help to extend the range of neurobiological investigations of the song system to include circuitry controlling such functionally related behaviors as aggression and reproduction.
Phase super-resolution using a photonic crystal fibre

Measurement, whilst being physically fundamental, is also fundamentally physical. Classical interferometric measurements suffer from physical limitations where the shot noise limit forms an upper bound of √n on a phase shift Δφ that can be resolved, with n being the average number of photons detected, making their applicability in modern nanoscale experiments quite restricted. Exotic quantum states such as maximally entangled NOON states (|N0〉A;B +|0N〉A;B)/√2, where N is the number of entangled photons are of particular importance as they have repeatedly been shown to exhibit phase super-resolution [1,2]. Interesting post selection schemes [2] and time-reversed detection schemes [3] have been investigated for phase estimation using NOON states. These methods are inherently non-deterministic at the preparation [2] or measurement [3] stage and thus do not optimise resources, for instance the number of photons passing through the sample greatly exceeds those used in the measurement.
Evolving Dynamical Neural Networks for Adaptive Behavior

We would like the behavior of the artificial agents that we construct to be as well-adapted to their environments as natural animals are to theirs. Unfortunately, designing controllers with these properties is a very difficult task. In this article, we demonstrate that continuous-time recurrent neural networks are a viable mechanism for adaptive agent control and that the genetic algorithm can be used to evolve effective neural controllers. A significant advantage of this approach is that one need specify only a measure of an agent's overall performance rather than the precise motor output trajectories by which it is achieved. By manipulating the performance evaluation, one can place selective pressure on the development of controllers with desired properties. Several novel controllers have been evolved, including a chemotaxis controller that switches between different strategies depending on environmental conditions, and a locomotion controller that takes advantage of sensory feedback if available but that can operate in its absence if necessary.
Control, Affect and Cognition Trust in Determining IT Offshoring Outsourcing Service Quality

Trust and control are essential in inter-organization collaboration. This paper extends existing literatures by empirically testing the different effects of formal and informal control on cognition and affection trust and their impacts on service quality in IT offshore outsourcing. The results show that formal control and affect trust contribute to service quality. However, informal control negatively impacts service quality. Additionally, although both informal and formal control positively relate to trust, the effect of informal control on affect trust is stronger than that of formal control.
Power Sharing Method for a Grid connected Microgrid with Multiple Distributed Generators

In this paper, a grid connected microgrid with multiple inverter-based distributed generators (DGs) is considered. DG in FFC mode regulates the microgrid as a controllable load from the utility point of view as long as its output is within the capacity limit. The transition mode causes a change in frequency of microgrid due to the loss of power transferred between main grid and microgrid. Frequency deviation from the nominal value can exceed the limit if the loss of power is large enough. This paper presents a coordinated control method for inverter-based DGs so that the microgrid is always regulated as a constant load from the utility viewpoint during grid connected mode, and the frequency deviation in the transition mode is minimized. DGs can share the load by changing their control modes between UPC and FFC and stabilize microgrid during transition.
An 11 b 7 ps Resolution Two-Step Time-to-Digital Converter With 3-D Vernier Space

This paper presents a fine-resolution time-to-digital converter (TDC) with a large dynamic range using a 3-D Vernier space. Despite the wide dynamic range, the required delay cells in the delay-lines are minimized, leading to better power efficiency. The proposed TDC also exploits the redundancy and error-correction technique to solve the offset error of coarse conversion in the 3-D Vernier space architecture. The TDC is implemented using a 0.13- μm CMOS process. The measurement result shows a dynamic range with an 11-bit 6.98-ps resolution, an integrated nonlinearity of ±1.5 LSB, a power consumption of 328.8 μW, and a die area of 0.28 mm2.
Wafer level warpage modeling methodology and characterization of TSV wafers

Through-silicon-via (TSV) approach has been widely investigated recently for three-dimensional (3D) electronic packaging integration. TSV wafer warpage is one of the most challenges for successfully subsequent processes. In this work, wafer level warpage modeling methodology has been developed by finite element analysis (FEA) method using equivalent material model. The developed modeling methodology has been verified by numerical results and experiment data. With using the developed model, wafer warpage has been simulated and analyzed by considering different factors such as annealing temperature, Cu overburden thickness, TSV depth and diameter. Simulation results show that wafer warpage increases with increasing annealing temperature and increasing Cu overburden thickness. Such findings have been successfully used in the TSV process optimization to reduce wafer warpage after annealing process. Submodeling methodology has also been developed to determine wafer stress accurately. Wafer bending stress is larger at wafer surface and close to the TSV edge. Bending stress is higher at the edge of TSV with finer pitch.
Shear Locking-Free Finite Element Formulation for Thick Plate Vibration Analysis

The basic equations of the Mindlin thick plate theory are specified as starting point for the development of a new thick plate theory in which total deflection and rotations are split into pure bending deflection and shear deflection with bending angles of rotation, and in-plane shear angles. The equilibrium equations of the former displacement field are condensed into one partial differential equation for flexural vibrations. In the latter case two differential equations for in-plane shear vibrations are obtained and they are similar to the well-known membrane equations. Physical background of the derived equations is analysed in case of a simply supported square plate. Rectangular shear locking-free finite element for flexural vibrations is developed. For in-plane shear vibrations ordinary membrane finite elements can be used. Natural modes of plate layers in in-plane shear vibrations are the same as membrane modes, while natural frequencies have to be transformed. Application of the presented theory is illustrated in a case of simply supported and clamped square plate. Problems are solved analytically and by FEM. The obtained results, compared with the relevant ones available in literature, are discussed.
Multiparametric analysis of normal and postchemotherapy bone marrow: Implication for the detection of leukemia‐associated immunophenotypes

The knowledge of normal marrow is mandatory to assess the malignant counterpart of normal cells and define leukemia‐associated immunophenotypes (LAIPs). In this study, the expression of a variety of antigens expressed in normal and postchemotherapy bone marrow (BM) was analyzed to provide a frame of reference for the identification of myeloid LAIPs.
Francisella philomiragia Bacteremia in a Patient with Acute Respiratory Insufficiency and Acute-on-Chronic Kidney Disease

ABSTRACT Francisella philomiragia is a very uncommon pathogen of humans. Diseases caused by it are protean and have been reported largely in near-drowning victims and those with chronic granulomatous disease. We present a case of F. philomiragia pneumonia with peripheral edema and bacteremia in a renal transplant patient and review the diverse reports of F. philomiragia infections.
Improved binary HOG algorithm and possible applications in car detection

In this paper we investigate how the HOG algorithm can be successfully modified to work on binary information. We detail the area and the performance evolution when the standard HOG algorithm is adjusted to work on binary images, and introduce an improved binary HOG algorithm. Compared to the HOG working on grayscale images, the improved binary HOG has an extremely small implementation area. Its performance is practically identical to that of the original HOG working on binary images, but reduced compared to that working on grayscale images. Given its extremely small area, the new algorithm can be acceptable for many applications, or it can be used in more complex systems, as part of a preliminary detection stage.
Density evolution for joint source-channel asymmetric Slepian-Wolf coding with parity based approach

In this paper, iterative codeword-averaged density evolution (DE) formulas for low-density parity-check (LDPC) codes are developed for joint source-channel asymmetric Slepian-Wolf (ASW) coding of two correlated binary nonuniform memoryless sources with parity based approach. In order to be compatible with the parity based approach, a new ensemble definition of irregular codes being able to distinguish the degree distributions of the edges incident to information variable nodes and the edges incident to parity-checking variable nodes is introduced. Extensive simulations demonstrate the effectiveness of the proposed DE for joint source-channel ASW coding with parity based approach.

Assessing skin prick tests reliability in ECRHS-I.

INTRODUCTION Atopy, the clinical definition of an immunoglobulin E (IgE) high-responder, can be documented either by the detection of IgE antibodies in serum or by a positive skin prick test. Epidemiological studies use different reaction sizes to define a skin test reaction as positive or negative. The aim of the study was to identify the best cut-off level for skin prick tests. METHOD Using the data collected during the European Community Respiratory Health Survey (ECHRS I) the association of serum allergen-specific IgE and skin prick tests [Dermatophagoides pteronyssinus (Der p), cat, timothy grass and Cladosporium] were assessed. RESULTS The proportion of the 11 355 subjects (49.9% men), with positive skin tests ranged from 10.4% (cut-off >5 mm) to 20.9% (cut-off >0 mm) for Der p, 3.5-10.2% for cat, 9.3-16.6% for timothy grass and 0.2 and 2.3% for Cladosporium. For identifying subjects with detectable specific IgE (>0.35 kU/l) the most appropriate cut-off appeared to be over 0 mm for Der p, cat and timothy grass (Youden Index over 0.81). However, the relationship between serum IgE and skin prick test for Cladosporium was weak (Youden index under 0.56). CONCLUSION In epidemiological studies, a single method may be chosen to assess allergenic sensitivity. A cut-off level of over 0 mm for skin prick tests was best at identifying those with allergen-specific IgE.
Circadian phase in delayed sleep phase syndrome: predictors and temporal stability across multiple assessments.

STUDY OBJECTIVES To assess temporal stability across multiple assessments and predictors of circadian phase in participants with delayed sleep phase syndrome (DSPS), relative to normal-sleeping matched controls. DESIGN Circadian phase was assessed by salivary dim light melatonin onset (DLMO) during 3 laboratory visits, separated by at least 5 days--2 scheduled at the end of the week (Friday) and 1 scheduled at the end of the weekend (Sunday). PATIENTS Eight young volunteers who met International Classification of Sleep Disorders-Revised criteria for DSPS, and 8 age- and sex-matched controls (age range 19-27 years old). INTERVENTIONS N/A. MEASUREMENTS AND RESULTS As expected, salivary DLMO occurred significantly later in patients with DSPS than in controls (F 10.561, p = .006). However, circadian phase did not change significantly across the 3 DLMO assessments in either group. Estimations of circadian phase were not significantly different in the assessments conducted on weekdays versus weekends. Predictors of circadian phase included time of morning light exposure (R2 = 0.777; p < .001), recent wake time (R2 = 0.701, p < .001), and self-reported chronotype (R2 = 0.320, p = .016). DLMO preceded wake time in both groups by approximately 10.75 hours. CONCLUSIONS Across serial laboratory assessments on an ad lib sleep schedule, patients with DSPS appeared more similar to than different from normal-sleeping control subjects, except for a stable delay in circadian phase.
Observer Design for a Class of Switched Systems

The main contribution of this paper is a new approach to the design of state observers for a class of switched systems. This class of systems allows for switching among Linear Parameter Varying (LPV) systems affected by unmeasurable input/output disturbances. The proposed observers have guaranteed performance even during the switching transient, and "mitigate" the effect of unmeasured disturbance. Moreover, it is shown that observer design can be done using linear programming. Finally, a numerical example is presented which shows the efficacy of the proposed approach.
Central Finite Volume Methods Applied in Relativistic Magnetohydrodynamics: Applications in Disks and Jets

We have developed a new computer program in Fortran 90, in order to obtain numerical solutions of a system of Relativistic Magnetohydrodynamics partial differential equations with predetermined gravitation (GRMHD), capable of simulating the formation of relativistic jets from the accretion disk of matter up to his ejection. Initially we carried out a study on numerical methods of unidimensional Finite Volume, namely Lax-Friedrichs, Lax-Wendroff, Nessyahu-Tadmor method and Godunov methods dependent on Riemann problems, applied to equations Euler in order to verify their main features and make comparisons among those methods. It was then implemented the method of Finite Volume Centered of Nessyahu-Tadmor, a numerical schemes that has a formulation free and without dimensional separation of Riemann problem solvers, even in two or more spatial dimensions, at this point, already applied in equations GRMHD. Finally, the Nessyahu-Tadmor method was possible to obtain stable numerical solutions without spurious oscillations or excessive dissipation from the magnetized accretion disk process in rotation with respect to a central black hole (BH) Schwarzschild and immersed in a magnetosphere, for the ejection of matter in the form of jet over a distance of fourteen times the radius of the BH, a record in terms of astrophysical simulation of this kind. Also in our simulations, we managed to get substructures jets. A great advantage obtained was that, with the our code, we got simulate GRMHD equations in a simple personal computer. Keywords—Finite Volume Methods, Central Schemes, Fortran 90, Relativistic Astrophysics, Jet.
Enacted Sexual Stigma, Stigma Consciousness, and Subjective Happiness Scale Adaptation

Violence against people due to their sexual orientation is a phenomenon that exists within a framework of sexual stigma and sexual prejudice that can result in enacted stigma. The present study primarily aimed to validate the Stigma Consciousness Questionnaire (SCQ) and the Subjective Happiness Scale (SHS; for lesbian, gay, and bisexual [LGB] populations) in the Spanish context by using samples from two countries (Spain [N = 157] and the United States [N = 83]). Also, to examine how the construct of stigma consciousness correlates with anti-LGBQ (anti–lesbian, gay, bisexual, and queer) hate crime victimization and violent incidents, as well as examine whether the former influences subjective happiness. The population from the United States reported higher stigma consciousness and received more anti-LGBQ threats and insults. Hate crime victimization was the same across the two samples and positively correlated with violent incidents in both samples. Subjective happiness was negatively correlated with SCQ, although its subscales it did not correlate with enacted stigma measures.
