Travelling Wave Multipole Field Electromagnetic Launcher: An SOVP Analytical Model (2013)

The problem of the evaluation of eddy currents induced in a conductive cylinder is, here, reconsidered under the light of possible application in the electromagnetic launch context. In particular, we derive an analytical solution when the system is excited by a sinusoidal current flowing in a saddle coil moving in the axial direction. Subsequently, we consider an arrangement of such coils distributed in the axial and azimuth direction. When properly fed, they produce a travelling wave of flux distribution, which is able to exert a thrust force on the conductive cylinder. Since the governing vector field equation is not separable in the cylindrical coordinates, an approach based on the second-order vector potential formulation has been, here, adopted. Scalar field equations are obtained whose solutions are expressed in terms of Bessel functions.
The Manufacturing Resource Modeling of Multistage Manufacturing System Based on the Capacity Manufacturing Unit (2010)

The manufacturing capacity-oriented manufacturing resource model of multistage manufacturing system was presented to achieve the manufacturing resource sharing among the enterprises. This model abstracted various resources as capacity manufacturing unit to accommodate the manufacturing resource sharing. The manufacturing process extraction and graphical description methods based on resource were put forward, which solved the disjointedness problem between resource model and application through related information integration. This model achieves effective equipment state monitoring, personnel configuration and product man-hour tracking in the enterprise and realizes the manufacturing resource sharing based on manufacturing capacity in networked manufacturing environment, so that to make the capacity of enterprises clear and maximum.
Flatness improvement for a shunt-peaked ultra-wideband low noise amplifier (2010)

A novel configuration to achieve flat gain in wideband low noise amplifiers (LNA) is presented. It consists of a conventional shunt-peaking resistor, decoupled from the cascode stage through a capacitor. A trade-off between the voltage headroom and bandwidth is obtained, improving the traditional shunt-peaking load. As an example, two LNAs for ultra-wideband (UWB), operating for mode I (3.1 to 4.8 GHz), are designed in CMOS 0.35 μm technology. The measured power gain is fairly flat, approximately 10 dB, for frequencies ranging from 3.1 to 5 GHz.
Exploring the Implications of Heterogeneous Network Perspectives on Teaching Practicum (2020)

This study aims to explore the implications of heterogeneous network on teaching practicum as one of the attempts to respond the changes in future society and education. The study was conducted by reviewing the theoretical background related to the actor-network theory and heterogeneous networks and discussing the implications for teaching practicum based on this. As a result of the study, it was found that the Actor-Network Theory and heterogeneous network perspectives have the following implications for teaching practicum. First, teaching practicum should be recognized as a heterogeneous network composed of various actors. Second, it is necessary to pay attention to the translation process that emerges from the activity of teaching practicum. Third, it is also necessary to pay attention to things and their relationship with other actors in the activity of teaching practicum. Based on these results, some suggestions for the development of teaching practicum program were discussed.
Multimodality imaging methods and systemic biomarkers in classical low-flow low-gradient aortic stenosis: Key findings for risk stratification (2023)

Infrared Visualization of Automotive Paint Spray Transfer Process (2009)

An Infrared thermography based visualization technique for automotive paint spray is presented. Two common automotive paint applicators were studied using this technique and the results presented. The paint applicators studied were high-speed rotary bell atomizer and low pressure air atomizer. The technique uses a uniformly heated blackbody emitter as a background. The emitted infrared energy from the background passing through the spray is attenuated by the droplets in the spray. The attenuated intensity is captured by an infrared camera, to form a two-Dimensional image of the spray flow field. From the acquired intensity image, the entire spray flow field structure is visualized and the result discussed.
Sensorless control of single-inverter dual-motor ac brushless drives (2017)

The paper deals with the vector control of two surface-mounted permanent-magnet (PM) synchronous-motors in configuration “single-inverter dual-motor”, operating also with unbalanced loads. Since this structure is justified by the objective of obtaining low cost drives, a low computation burden sensorless method is proposed in order to further reduce the system complexity. A very simple algorithm for position/speed estimation coupled with a hybrid adaptive Phase-Locked Loop is indeed sufficient to achieve satisfactory results also in heavy transient operations. Furthermore, a novel control strategy is conceived with reference to an “equivalent” motor, whose rotor position is the average of the separately evaluated positions of the two PM motors. The proposed control technique is validated by an extensive numerical campaign.
Uptake and Translocation of Diallate in Wheat, Barley, Flax, and Wild Oat (1968)

Uptake and translocation of 14 C label from S -2,3-dichloroallyl N,N -diisopropylthiolcarbamate (diallate) by roots and coleoptiles of wild oat ( Avena fatua L.), wheat ( Triticum aestivum L., var. Selkirk), barley ( Hordeum vulgare L., var. Traill), and flax ( Linum usitatissimum L., var. Bolley) were compared. The pattern of 14 C label uptake and movement was similar in wild oat, barley, and wheat. However, translocation of the 14 C label to the roots of wild oat was less than for barley. Although differential uptake and translocation per se did not appear to account for the selectivity of diallate for wild oat, some differences in translocation may have beep the result of metabolic breakdown products.

Three-Dimensional Moment Invariants (1980)

Recognition of three-dimensional objects independent of size, position, and orientation is an important and difficult problem of scene analysis. The use of three-dimensional moment invariants is proposed as a solution. The generalization of the results of two-dimensional moment invariants which had linked two-dimensional moments to binary quantics is done by linking three-dimensional moments to ternary quantics. The existence and number of nth order moments in two and three dimensions is explored. Algebraic invariants of several ternary forms under different orthogonal transformations are derived by using the invariant property of coefficients of ternary forms. The result is a set of three-dimensional moment invariants which are invariant under size, orientation, and position change. This property is highly significant in compressing the data which are needed in three-dimensional object recognition. Empirical examples are also given.

Assessment of the Intestinal Absorption of Higher Olefins by the Everted Gut Sac Model in Combination with In Silico New Approach Methodologies (2022)

To reduce the number of animals and studies needed to fulfill the information requirements as required by Registration, Evaluation, Authorisation and Restriction of Chemicals (REACH) (EC no. 1907/2006), a read-across approach was used to support approximately 30 higher olefins. This study aimed to assess the absorption potential of higher olefins through the gut wall as the experimentally determined bioavailability which would strengthen the read-across hypothesis and justification, reducing the need for toxicity studies on all of the higher olefins. The absorption potential of a series of higher olefins (carbon range from 6 to 28, with five configurations of the double bond) was determined in the in vitro everted rat small intestinal sac model and subsequently ranked. In addition, in silico approaches were applied to predict the reactivity, lipophilicity, and permeability of higher olefins. In the in vitro model, everted sacs were incubated in "fed-state simulated small intestinal fluid" saturated with individual higher olefins. The sac contents were then collected, extracted, and analyzed for olefin content using gas chromatography with a flame ionization detector. The C6 to C10 molecules were readily absorbed into the intestinal sacs. Marked inter-compound differences were observed, with the amount of absorption generally decreasing with the increase in carbon number. Higher olefins with ≥C14 carbons were either not absorbed or very poorly absorbed. In the reactivity simulation study, the reactivity is well described by the position of the double bond rather than the number of carbon atoms. In the lipophilicity and permeability analysis, both parameter descriptors depend mainly on the number of carbon atoms and less on the position of the double bond. In conclusion, these new approach methodologies provide supporting information on any trends or breakpoints in intestinal uptake and a hazard matrix based on carbon number and position of the double bond. This matrix will further assist in the selection of substances for inclusion in the mammalian toxicity testing programme.
Extraction of Effective Oxide Thickness for SOI FINFETs With High- $\kappa$/Metal Gates Using the Body Effect (2010)

Conformal Parallel Plate Waveguide Polarizer Integrated in a Geodesic Lens Antenna (2022)

Here, we propose a low-profile polarizing technique integrated in a parallel plate waveguide (PPW) configuration, compatible with fully metallic geodesic lens antennas. The geodesic shape of the antenna is chosen to resemble the operation of a Luneburg lens. The lens is fed with 11 waveguide ports with 10° separation producing 11 switchable beams in an angular range of <inline-formula xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"> <tex-math notation="LaTeX">$\pm \mathrm{50}^{\circ }$ </tex-math></inline-formula> . Two metallic polarizing screens are loaded into the aperture of the antenna to rotate the electric field from a vertical linear polarization, which is the polarization of the transverse electromagnetic (TEM) mode supported in the lens, to a <inline-formula xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"> <tex-math notation="LaTeX">$+ \mathrm{45}^{\circ }$ </tex-math></inline-formula> linear polarization. Since the polarizing unit cells are integrated into the aperture of the antenna, the final design is compact. In addition, the size of the polarizing unit cells is about <inline-formula xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"> <tex-math notation="LaTeX">$0.55\lambda $ </tex-math></inline-formula> at the central frequency of operation making the antenna suitable to produce an array formed of stacked lenses. A prototype of the antenna in the <inline-formula xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"> <tex-math notation="LaTeX">$\text{K}_{\text {a}}$ </tex-math></inline-formula> -band was manufactured and tested, verifying the performance obtained in simulations.
Photo-Induced Nanopatterns on the Surface of C60 Single Crystals (1999)

Photo-induced surface reconstruction of molecular materials has been demonstrated for the first time using C60 as a model. The authors explain why C60 single crystals are good candidates to show photo-induced surface reconstruction and give experimental details. Reconstruction effects that depend on both the lattice symmetry and light polarization are shown to suggest that the phenomenon arises from a cooperative interaction between the photo-induced collective molecular displacement and the anisotropic lattice structure of the crystals.
Determination of flat band voltage in thin film transistors: The case of amorphous-indium gallium zinc oxide (2012)

Accurate knowledge of the gap density of states (DOS) is of paramount importance for process control and modelling of thin-film transistors (TFTs). We present here an approach for flat band determination, based on the combined analysis of transfer and capacitance-voltage characteristics. The method is independent from the DOS knowledge and requires no fitting parameters. Applied here to the case of amorphous indium gallium zinc oxide TFTs, our approach yields key device parameters, helping identification of the physical mechanisms responsible for device to device variations and degradation phenomena. It appears in particular capable to differentiate between interface and bulk effects.
Influence of themicrostructure on the corrosion behaviour in a sulphuric solution of cast carbon steels as characterized by electrochemical impedance spectroscopy. Part 2: Effect of the preliminary hardening by compression (2015)

In this second part this is in their plastically deformed states that the four carbon steels Fe-xC (x varying from 0 to 1.6 wt.%C) were tested in electrochemical impedance spectroscopy. Performed in the same molar sulphuric solution and following the same procedures, these EIS runs led to Nyquist semi-circles the exploitation of which allowed specifying the evolution of the transfer resistance Rtand of the double layer capacity Cdcwith time during one hour of immersion. All these hardened steels were initially and remain in an active state characterized by low Rt values. Clear dependence of Rt and Cdc on immersion time and on the steel carbon content were highlighted, despite that the deformation ratios were not exactly the same for all steels. However the variations of Rt and Cdc versus the carbon content were inversed by comparison to the results obtained in the first part for the not deformed states. Further investigations must be done to clarify the influence of hardening on these properties, notably by imposing much higher amounts of plastic deformation
Mutational Analysis of the Tyrosine Phosphatome in Colorectal Cancers (2004)

Tyrosine phosphorylation, regulated by protein tyrosine phosphatases (PTPs) and kinases (PTKs), is important in signaling pathways underlying tumorigenesis. A mutational analysis of the tyrosine phosphatase gene superfamily in human cancers identified 83 somatic mutations in six PTPs (PTPRF, PTPRG, PTPRT, PTPN3, PTPN13, PTPN14), affecting 26% of colorectal cancers and a smaller fraction of lung, breast, and gastric cancers. Fifteen mutations were nonsense, frameshift, or splice-site alterations predicted to result in truncated proteins lacking phosphatase activity. Five missense mutations in the most commonly altered PTP (PTPRT) were biochemically examined and found to reduce phosphatase activity. Expression of wild-type but not a mutant PTPRT in human cancer cells inhibited cell growth. These observations suggest that the mutated tyrosine phosphatases are tumor suppressor genes, regulating cellular pathways that may be amenable to therapeutic intervention.
Fractal geometry as a means of studying trabecular bone structure (2002)

Cross-sectional quantitative computed tomography (QCT) images of dried excised vertebral bodies, (density ranging from 76-220 mg/cm/sup 3/), immersed in saline, in conjunction with fractal geometry methods were used to characterize the trabecular matrix. An automatic boundary tracking algorithm was used to identify the trabecular-bone and bone marrow interface, and a box-counting algorithm was used to estimate the fractal dimension of the trabecular boundary. Using this technique, for fractal objects, if the boundary being analyzed is covered with boxes of differing sizes, epsilon , then the number of boxes N required to cover the surface increases indefinitely according to the relation N= epsilon /sup -D/, where D is the fractal dimension. Using this relationship, it was found that the trabecular bone boundary is a fractal of dimension ranging from 1.57 to 1.72. Analysis and technique-dependent factors that affect the estimated fractal dimensional are also discussed. The fractal dimension calculated depended on the range of epsilon values selected for the calculation of the dimension D, and for the same boundary the D varied from 1.58 to 1.81.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
Biomolecular Simulations: Recent Developments in Force Fields, Simulations of Enzyme Catalysis, Protein-Ligand, Protein-Protein, and Protein-Nucleic Acid Noncovalent Interactions (2001)

Computer modeling has been developed and widely applied in studying molecules of biological interest. The force field is the cornerstone of computer simulations, and many force fields have been developed and successfully applied in these simulations. Two interesting areas are (a) studying enzyme catalytic mechanisms using a combination of quantum mechanics and molecular mechanics, and (b) studying macromolecular dynamics and interactions using molecular dynamics (MD) and free energy (FE) calculation methods. Enzyme catalysis involves forming and breaking of covalent bonds and requires the use of quantum mechanics. Noncovalent interactions appear ubiquitously in biology, but here we confine ourselves to review only noncovalent interactions between protein and protein, protein and ligand, and protein and nucleic acids.

Table 2 demonstrates the number of patients needing revision of their shunt systems. Forty percent of the total group examined (643 patients), underwent revision surgery. The total of 1,019 revisions were sub­ divided as follows: ventricular catheter 37%, flushing device or valve, 11%, atrial catheter, 42%, and peritoneal catheter, 10%. In other words, the outflow of the shunt system caused 52% of all complications. It should be noted that revision rates at different clinics ranged from 28% to 56%. In most cases (56%) only one revision was necessary. Two revisions were needed by 28%, 10% needed three, and 6% needed four or more revisions. The latter group included individual cases known to have an extremely high rate of complications (Table 3).
