Electrospun Fibers of Poly(Vinylidene Fluoride-Trifluoroethylene)/Poly(3-Hexylthiophene) Blends from Tetrahydrofuran (2012)

Fibers of the ferroelectric poly(vinylidene fluoride-trifluoroethylene) blended with the semiconducting regio-regular poly(3-hexylthiophene) polymer – (PVF2-TrFE/P3HT) were prepared for the first time in air at room temperature using the electrospinning technique that is cheap, fast and reliable. The presence of P3HT assisted in fabrication of PVF2-TrFE fibers at low polymer concentrations in tetrahydrofuran (THF) than currently possible, with the fiber diameters increasing as the concentration of PVF2-TrFE increases. UV/VIS spectroscopy showed that P3HT was uniformly incorporated into the PVF2-TrFE solution with no polymer segregation. Scanning electron microscope images show a reduction in the beading effect and an increase in the quantity of fiber formation when P3HT is incorporated into the solution.
Structural and Electrochemical Characterization of Ethylenediaminated Single-Walled Carbon Nanotubes Prepared from Fluorinated SWCNTs (2014)

We prepared ethylenediaminated single-walled carbon nanotubes (SWCNTs) from fluorinated SWCNTs by substituting fluorine groups with ethylenediamine groups. The ethylenediaminated SWCNTs were characterized by scanning electron microscopy (SEM), high-resolution transmission electron microscopy (HRTEM), Raman scattering spectroscopy, X-ray diffraction, X-ray photoelectron spectroscopy, Brunauer–Emmett–Teller surface area measurement by nitrogen adsorption, contact angle measurement, zeta potential analysis, and thermogravimetry. In addition, the properties of 30 wt % sulfuric acid aqueous electrolyte-based electric double-layer supercapacitors (EDLSCs) with free-standing ethylenediaminated SWCNT electrodes were investigated. The degree of ethylenediamine functionalization was 0.603 mmol/g and 1.46 μmol/m2, and the specific surface area was ∼413.3 m2/g. From HRTEM observation, isolated nanotubes disentangled from the bundled SWCNTs were present in many observed areas, and the structures retained a nanotube skeleton. The properties of the EDLSCs with the ethylenediaminated SWCNT electrodes included an average specific capacitance of 94 F/g at a low scan rate of 10 mV/s and an energy density of 2.6 Wh/kg at a power density of 0.24 kW/kg. The EDLSCs exhibited an average specific capacitance of 67 F/g at a high scan rate of 1000 mV/s and an energy density of 1.3 Wh/kg at a power density of 24 kW/kg, values that were superior to those of carboxylated SWCNT electrodes.

In this review the genus Axinella and some of the compounds isolated from this genus have been evaluated from the view point of biological activities including antimicrobial, cytotoxic, anti-inflammatory and antioxidant activities.
DEMOCRACIA E PLANEJAMENTO TERRITORIAL: Desenvolvimento urbano de Goiânia e Planos Diretores Participativos na RMG (2010)

The deterioration of the quality of life in the great Brazilian cities has taken to the reflection a reasonable number of researchers of social sciences in Brazil in this beginning of century.Although they already had been debated previously, it is in the period of the democratization of years 1980 that the urban problematic in Brazil acquires a content properly politician.Through the National Movement for Urban Reform (MNRU) (MNRU) the claims gain prominence relative to the levels of social injustice in the urban way, as well as the pressures for the democratization for planning and management.In this perspective, the processes of definition of the urban politics are, now, demarcated for a new relation between State and society.In the same time, the performance of the agents in the spaces of decision and control is guided by new forms and contents.This study aimed to identify the contents of popular participation and democratization in Participative Director Plans from four cities of Goiânia's Metropolitan Region, elaborated between the years of 2004 and 2008.
Growth and electrostrictive properties of Pb(Mg1/3Nb2/3)O3 crystals (1999)

Transparent and stoichiometric lead-magnesium-niobate crystals were grown by the Bridgman method. Crystals of centimeter size were obtained without material loss by employing self-seeded and seeded techniques using sealed platinum crucibles. The fastest growth direction was found to be pseudocubic 〈111〉. As-grown crystals showed a broad absorption band centered near λ=600 nm and an OH absorption near λ=2830 nm. The electrostrictive coefficient Q11 was determined to be 1.15×10−2 m4 C−2 from the measured strain and polarization.
Ninja on a Plane: Automatic Discovery of Physical Planes for Augmented Reality Using Visual SLAM (2007)

Most work in visual augmented reality (AR) employs predefined markers or models that simplify the algorithms needed for sensor positioning and augmentation but at the cost of imposing restrictions on the areas of operation and on interactivity. This paper presents a simple game in which an AR agent has to navigate using real planar surfaces on objects that are dynamically added to an unprepared environment. An extended Kalman filter (EKF) simultaneous localisation and mapping (SLAM) framework with automatic plane discovery is used to enable the player to interactively build a structured map of the game environment using a single, agile camera. By using SLAM, we are able to achieve real-time interactivity and maintain rigorous estimates of the system's uncertainty, which enables the effects of high quality estimates to be propagated to other features (points and planes) even if they are outside the camera's current field of view.
Sites phosphorylated in bovine cardiac troponin T and I (1990)

Bovine cardiac troponin isolated in a highly phosphorylated form shows four 31P-NMR signals [Beier, N., Jaquet, K., Schnackerz, K. & Heilmeyer, L.M.G. Jr (1988) Eur. J. Biochem. 176, 327-334]. Troponin I, which contains phosphate covalently linked to serine-23 and/or -24 [Swiderek, K., Jaquet, K., Meyer, H. E. & Heilmeyer, L. M. G. Jr (1988) Eur. J. Biochem. 176, 335-342], shows three resonances. Mg2(+)-saturation of holotroponin shifts these troponin I resonances to higher fields. Direct binding of Mg2+ to the phosphate groups can be excluded. Both these serine residues of troponin I, 23 and 24, are substrates for cAMP- and cGMP-dependent protein kinases as well as for protein kinase C. Isolated bovine cardiac troponin T contains 1.5 mol phosphoserine/mol protein, indicating that minimally two serine residues are phosphorylated. One phosphoserine residue is located at the N-terminus. An additional phosphoserine is located in the C-terminal cyanogen bromide fragment, CN4, which contains covalently bound phosphate. Protein kinase C phosphorylates serine-194, thus demonstrating exposure of this residue on the surface of holotoponin.
Shifting methods: adopting a design for manufacture flow (2004)

Unlike traditional design rule checks (DRCs), which have a clear pass or fail definition, yield issues, such as density and antenna checks, are dependent on a number of variables, resulting in a yes, no or maybe paradigm. These issues, which have a major impact on total chip yield, have typically been identified as design constraints and embedded in DRC rule files. But there is little in the way of information on how a change in layout relates to overall improvement in yield. With advanced processes of 130nm and smaller, designs that are verified DRC clean can still result in poorly yielding or even non-functioning silicon. For this reason, a new method of communication is needed between designer and manufacturer for determining yield issues. Rather than being provided information on a simple pass/fail basis, designers need immediate access from the manufacturer to how various layout characteristics impact chip yield. This new communication loop is the first and necessary step in adopting and implementing a design for manufacture (DFM) flow. Such an approach identifies trouble spots and provides the important data that allows the designer to determine a cost/yield analysis. Designers will be deciding on and implementing a "fix or fab" methodology, resulting in greater yield and control.
FGF-1 and FGF-7 induce distinct patterns of growth and differentiation in embryonic lung epithelium (1997)

Fibroblast growth factors (FGFs) and receptors (FGFRs) are expressed in the developing lung and appear to be major regulators of lung growth and differentiation. By using mesenchyme-free lung epithelial cultures we show that FGF-1 (aFGF) and FGF-7 (KGF) produce different effects in the developing lung. FGF-1 stimulates epithelial proliferation that results in bud formation (branching), while FGF-7 promotes epithelial proliferation that leads to formation of cyst-like structures. In addition, FGF-7 stimulates epithelial differentiation, stimulating expression of SP-A and SP-B mRNA throughout the explant, and inducing formation of focal areas of highly differentiated cells. The FGF-1 effects on differentiation are limited to induction of surfactant protein SP-B mRNA at the tips of the explant. The FGF-induced patterns of growth appear to correlate with the distribution of epithelial FGFRs mRNAs; FGFR-2 IIIb (KGFR) is diffusely expressed in the day 11 lung epithelium, while FGFR-4 appears in distal but not in proximal sites. We propose that cyst-like structures may result from FGF-7 binding to the uniformly distributed FGFR-2-IIIb. Lung bud formation may be regulated by FGF-1 and/or other ligands binding to FGFR-2 and a distally located FGFR, such as FGFR-4, leading to an increasing binding and activation of FGFRs at the tips of the explant. Thus, in the embryonic lung epithelium, growth effects of FGFs appear to be dependent on location of FGFRs, while effects on differentiation are ligand-dependent. Dev.

Ontology-based Dynamic Process Collaboration in Service-Oriented Architecture (2007)

Service collaboration is important in service- oriented architecture (SOA). While service collaboration protocols for data exchange are well explored, the dynamic process collaboration (DPC) is still a challenge. DPC requires not only exchanging meaningful information between collaboration parties, but also performing collaboration workflow matching based on collaboration ontology. To do this, DPC needs service collaboration ontology modeling, service collaboration discovery and establishment based on collaboration ontology and runtime recomposition capability. This paper presents an ontology-based dynamic process collaboration (ODPC) framework with these features to facilitate DPC.
A programmable instrumentation amplifier for 12b resolution systems (1982)

A complete monolithic instrumentation amplifier suitable for 12b resolution systems, affording pin programmable gains of 1, 10, 100 and 1000, with nonlinearity of < 0.005%, will be discussed.
Detection of Escherichia coli O157:H7 in raw meat by immunomagnetic separation and multiplex PCR. (2002)

The aim of this research was to elaborate fast and sensitive method ofdetection of E. coli O157:H7 in food samples. Raw ground meat obtained from retail was artificially inoculated with low numbers of E. coli O157:H7. 18 h enrichment culture allowed pathogenic bacteria to multiply to the levels detectable in multiplex PCR. Immunomagnetic separation with magnetic beads coated with an antibody against E. coli O157:H7 were used to concentrate target bacteria and to separate PCR inhibitors. A portion of the bacterial suspension was used in a multiplex PCR to amplify eae (attaching and effacing) gene, stx (shiga toxin) genes and 90 kbp plasmid. The sensitivity of E. coli O157:H7 detection method was shown to be 1 cfu per 25 g of food sample. The total analysis can be completed within 24 h, whilst traditional methods involves enrichment, direct plating and confirmation tests with entire time at least 3 days.
The Liver Toxicity Knowledge Base: A Systems Approach to a Complex End Point (2013)

Drug-induced liver injury (DILI) is a major concern in public health management, drug development, and regulatory implementation. The Liver Toxicity Knowledge Base (LTKB) was developed with the specific aim of enhancing our understanding of DILI. It seeks to achieve improvement in DILI prediction through integrated analysis of diverse sources of drug-elicited data. The project has also produced a centralized resource of data as well as predictive models that will be useful for research and drug regulation.
A mobile signing solution based on Personal Transaction Protocol and J2ME (2006)

E-business has been booming for years; however, transaction security is still the biggest worry in the E-business world. Public key infrastructure is introduced to protect electronic transactions, wherein digital signing plays an important role that provides authentication and non-repudiation services. A smart card-based hardware security module is able to provide signing service with strong tamper-resistant and mobility. However, since smart cards do not have I/O interfaces, a user may blindly sign a document that has been altered by a malicious application. Since mobile phones have user-friendly interfaces, strong computing power and short-distance wireless links, etc, they could be promising candidates for signing service. Some mobile phone-based signing solutions have been proposed as alternatives to smart cards. However, most of these solutions, including Zurich University's SIM based solution and Vodafone's mPKI, stick to GSM mobile networks. So far, there is no uniform standard for signing solution. In my thesis, a mobile phone-based signing solution that is based on the Personal Transaction Protocol (PTP) defined by MeT is proposed. However, the original PTP is designed to work in a personal environment, where all devices are trusted. My thesis proposed an improved PTP to allow it to work in a public environment. In addition, J2ME platform is chosen to be the development platform of the proposed solution. The J2ME's applicability is discussed according to the PTP server's development requirements. Finally, a PTP server's prototype is designed and developed to demonstrate the feasibility of the proposed solution.

VAR, SVAR and SVEC Models: Implementation Within<i>R</i>Package<b>vars</b> (2008)

The structure of the package vars and its implementation of vector autoregressive, structural vector autoregressive and structural vector error correction models are explained in this paper. In addition to the three cornerstone functions VAR(), SVAR() and SVEC() for estimating such models, functions for diagnostic testing, estimation of a restricted models, prediction, causality analysis, impulse response analysis and forecast error variance decomposition are provided too. It is further possible to convert vector error correction models into their level VAR representation. The different methods and functions are elucidated by employing a macroeconomic data set for Canada. However, the focus in this writing is on the implementation part rather than the usage of the tools at hand.
Impact of intermediate high temperature annealing on the properties of AlN/sapphire templates grown by metalorganic vapor phase epitaxy (2019)

In this work, we investigate AlN/sapphire templates grown by metalorganic vapor phase epitaxy (MOVPE) subjected to an intermediate high temperature annealing (HTA) step at different AlN film thicknesses. To avoid cracking of the MOVPE layers during HTA at 1700 °C these layers have to be grown under low incorporation of tensile strain. For each sample the growth is stopped at a certain thickness between 230 nm and 1.2 μm followed by HTA. X-ray rocking curve FWHM of 0002 and 10–12 reflections lead to an estimation of threading dislocation densities (TDD) as low as cm−2 for the thickest AlN layers of 880 nm and 1.2 μm after annealing. For all layer thicknesses MOVPE growth is subsequently continued to a total AlN layer thickness of 1.5 μm to reach for a smooth surface. The change of the AlN strain state after HTA leads to an increased wafer curvature at room temperature and compressive strain in the subsequently grown AlN layers increasing the wafer bow at room temperature. Hence, to serve as a base layer, e.g. for ultraviolet light emitting diodes, a trade-off between low TDD, surface smoothness and wafer bow has to be found.
Arabidopsis thaliana contains two differentially expressed 3-hydroxy-3-methylglutaryl-CoA reductase genes, which encode microsomal forms of the enzyme. (1994)

The enzyme 3-hydroxy-3-methylglutaryl-CoA reductase (HMGR; EC 1.1.1.34) catalyzes the first rate-limiting step in plant isoprenoid biosynthesis. Arabidopsis thaliana contains two genes, HMG1 and HMG2, that encode HMGR. We have cloned these two genes and analyzed their structure and expression. HMG1 and HMG2 consist of four exons and three small introns that interrupt the coding sequence at equivalent positions. The two genes share sequence similarity in the coding regions but not in the 5'- or 3'-flanking regions. HMG1 mRNA is detected in all tissues, whereas the presence of HMG2 mRNA is restricted to young seedlings, roots, and inflorescences. The similarity between the two encoded proteins (HMGR1 and HMGR2) is restricted to the regions corresponding to the membrane and the catalytic domains. Arabidopsis HMGR2 represents a divergent form of the enzyme that has no counterpart among plant HMGRs characterized so far. By using a coupled in vitro transcription-translation assay, we show that both HMGR1 and HMGR2 are cotranslationally inserted into endoplasmic reticulum-derived microsomal membranes. Our results suggest that the endoplasmic reticulum is the only cell compartment for the targeting of HMGR in Arabidopsis and support the hypothesis that in higher plants the formation of mevalonate occurs solely in the cytosol.

Advanced Cardiac Morphogenesis Does Not Require Heart Tube Fusion (2004)

The bilateral cardiac mesoderm migrates from the lateral region of the embryo to the ventral midline, where it fuses to form the primitive heart tube. It is generally accepted that migration and fusion are essential for subsequent stages of cardiac morphogenesis. We present evidence that, in Foxp4 mutant embryonic mice, each bilateral heart-forming region is capable of developing into a highly differentiated four-chambered mammalian heart in the absence of midline fusion. These data demonstrate that left-right chamber specification, cardiac looping, septation, cardiac myocyte differentiation, and endocardial cushion formation are preprogrammed in the precardiac mesoderm and do not require midline positional identity or heart tube fusion.
Wind Power Generation Prediction Based on LSTM (2019)

In recent years, with the increasing proportion of wind power generation, the impact of wind power generation on grid security is also growing. This makes the prediction accuracy of wind power generation higher and higher. This paper utilizes the LSTM model of the deep learning domain to predict wind power generation. Besides, Auto Encoder is employed to reduce the data dimension, improve the generalization ability of the model, and shorten the training time. Simulation experiments show that the LSTM model has better prediction accuracy than other machine learning model such as SVM.
