E-cadherin in gastric cancer (2006)

Cadherin is an adhesion molecule and a superfamily of calcium-mediated membrane glycoproteins. E-cadherin is the prototype of the class E-cadherin that links to catenins to form the cytoskeleton. Recent evidence has shown that E-cadherin not only acts as an adhesive, but also plays important roles in growth development and carcinogenesis. It has been recently viewed as an invasion as well as a growth suppressor gene. This review summarizes the recent discoveries on E-cadherin and its role in gastric cancer. In particular, our work on E-cadherin in gastric cancer, including its relation with Helicobacter pylori and clinical applications, are described in detail.
A reflected laser line approach for industrial robot calibration (2012)

This paper proposes a novel calibration approach for industrial robots. Unlike previous methods, the proposed approach introduces a completely new technique for automatically calibrating robots. The proposed system consists of an industrial robot manipulator, a laser fixture attached to the robot tool center point (TCP), a PC-based interface, and a new portable position sensitive device. This portable device comprised of two fixed position sensitive detectors (PSD's) tilted in an angle to reflect the laser line from one PSD to another. The new calibration approach is not only able to compute the joint offset parameters of the robot, but is also capable of simultaneously calibrating the robot's workpiece relationship. It was also designed to be faster yet simpler than other methods. Throughout this paper we present, analyze and compare both simulations and experimental results between the new proposed approach and our existing methods.

Using a Weighted Semantic Network for Lexical Semantic Relatedness (2013)

The measurement of semantic relatedness between two words is an important met-ric for many natural language processing applications. In this paper, we present a novel approach for measuring semantic re-latedness that is based on a weighted se-mantic network. This approach explores the use of a lexicon, semantic relation types as weights, and word definitions as a basis to calculate semantic related-ness. Our results show that our approach outperforms many lexicon-based methods to semantic relatedness, especially on the TOEFL synonym test, achieving an accu-racy of 91.25%. 1
Optical Measurements of the Thermal Conductivity of Porous SiO2 Films (2010)

Nanocomposites offer unique capabilities of controlling thermal transport through the manipulation of various structural aspects of the material. However, measurements of the thermal properties of these composites are often difficult, especially porous nanomaterials. Optical measurements of these properties, although ideal due to the noncontact nature, are challenging due to the large surface variability of nanoporous structures. Recently, a novel pump-probe geometry was used in Time Domain Thermoreflectance (TDTR) to determine the thermal conductivity of liquids. In this work, we develop a thermal algorithm to solve for the temperature change and heat transfer in this TDTR geometry in which a thin film which is subjected to a modulated heat source is sandwiched between two thermally conductive pathways. We validate our thermal algorithm with TDTR measurements of the thermal conductivity and on a series of porous SiO2-based nanostructured films.

Characterization of Inorganic Biocarriers That Moderate System Upsets during Fixed-Film Biotreatment Processes (1994)

Inorganic matrices were developed for fixed-film bioreactors affording protection to microorganisms and preventing loss of bioreactor productivity during system upsets. These biocarriers, designated Type-Z, contain ion-exchange properties and possess high porosity and a high level of surface area, which provide a suitable medium for microbial colonization. Viable cell populations of 10/g were attainable, and scanning electron micrographs revealed extensive external colonization and moderate internal colonization with aerobic microorganisms. Laboratory-scale bioreactors were established with various biocarriers and colonized with Pseudomonas aeruginosa, and comparative studies were performed. The data indicated that bioreactors containing the Type-Z biocarriers were more proficient at removing phenol (1,000 ppm) than bioreactors established with Flexirings (plastic) and Celite R635 (diatomaceous earth) biocarriers. More significantly, these biocarriers were shown to moderate system upsets that affect operation of full-scale biotreatment processes. For example, subjecting the Type-Z bioreactor to an influent phenol feed at pH 2 for periods of 24 h did not decrease the effluent pH or reactor performance. In contrast, bioreactors containing either Celite or Flexirings demonstrated an effluent pH drop to approximately 2.5 and a reduction in reactor performance by 75 to 82%. The Celite reactor recovered after 5 days, whereas the bioreactors containing Flexirings did not recover. Similar advantages were noted during either nutrient or oxygen deprivation experiments as well as alkali and organic system shocks. The available data suggest that Type-Z biocarriers represent an immobilization medium that provides an amenable environment for microbial growth and has the potential for improving the reliability of fixed-film biotreatment processes.
A Heuristic Placement Selection of Live Virtual Machine Migration for Energy-Saving in Cloud Computing Environment (2014)

The field of live VM (virtual machine) migration has been a hotspot problem in green cloud computing. Live VM migration problem is divided into two research aspects: live VM migration mechanism and live VM migration policy. In the meanwhile, with the development of energy-aware computing, we have focused on the VM placement selection of live migration, namely live VM migration policy for energy saving. In this paper, a novel heuristic approach PS-ES is presented. Its main idea includes two parts. One is that it combines the PSO (particle swarm optimization) idea with the SA (simulated annealing) idea to achieve an improved PSO-based approach with the better global search's ability. The other one is that it uses the Probability Theory and Mathematical Statistics and once again utilizes the SA idea to deal with the data obtained from the improved PSO-based process to get the final solution. And thus the whole approach achieves a long-term optimization for energy saving as it has considered not only the optimization of the current problem scenario but also that of the future problem. The experimental results demonstrate that PS-ES evidently reduces the total incremental energy consumption and better protects the performance of VM running and migrating compared with randomly migrating and optimally migrating. As a result, the proposed PS-ES approach has capabilities to make the result of live VM migration events more high-effective and valuable.

Preliminary Model Experiments in Redox Well Logging (with Applications to Mineral Exploration) (1969)

Preliminary Model Experiments in Redox Preliminary Model Experiments in Redox Well Logging (with Applications to Mineral Exploration) Abstract Model laboratory experiments were performed to simulate stratified sedimentary rocks drilled with fresh muds in which the only potential-contrasts in existence were redox [Eh] and potential-contrasts in existence were redox [Eh] and diffusion [Ed] potentials. It is shown that the conventional SP curve measures but a small fraction of the total redox potential contrast between the formations, potential contrast between the formations, whereas the redox log recorded in the wellbore may measure a large fraction of the Eh contrast. Experiments with simulated salt muds indicate that satisfactory measurements are achieved with the redox log, whereas the SP curve is completely suppressed. The SP curve appears as a subdued curve of the redox potential contrast between formations except that the SP curve is not responsive to the presence of hydrocarbons in clean sands nor to the water-oil contact. By contrast the redox log may be run in salt muds [inorganic salts] and it indicates the presence of hydrocarbons in formations and the presence of hydrocarbons in formations and the oil-water contact. However, the redox log may not be run satisfactorily when the mud is rich in organic substances such as oil and quebracho. Example logs illustrate the paper together with example surveys of redox potential measurements in exploration for oil and gas fields, for uranium and for native sulfur ore bodies. THE REDOX OR Eh POTENTIAL Oxidation-Reduction Potential [or ORP or redox potential or Eh] is a measure of the tendency for chemical species in ionic solution to change their oxidation or reduction state. It is also a quantitative measure of the energy of oxidation or of the electron-escaping tendency of a reversible oxidation-reduction system. Chemical reactions involving the transfer of electrons and protons, i.e., of electric charges, depend either upon the pH [a measure of the proton activity] or on the Eh [a measure of the electron activity] or on both pH and Eh of the systems in which the reactions take place. Such reactions at equilibrium are governed by the following general expression at standard conditions: (1) in which a is the number of protons [H+] and n is the number of electrons [e-] taking part in the reaction. The equilibrium conditions are thus represented by a straight line on a Cartesian plot of Eh vs pH, the slope of which is [60a/n] mv/pH unit. Eo is the standard potential of the reaction. potential of the reaction.

Freeform surfaces from single curved panels (2008)

Motivated by applications in architecture and manufacturing, we discuss the problem of covering a freeform surface by single curved panels. This leads to the new concept of semi-discrete surface representation, which constitutes a link between smooth and discrete surfaces. The basic entity we are working with is the developable strip model. It is the semi-discrete equivalent of a quad mesh with planar faces, or a conjugate parametrization of a smooth surface. We present a B-spline based optimization framework for efficient computing with D-strip models. In particular we study conical and circular models, which semi-discretize the network of principal curvature lines, and which enjoy elegant geometric properties. Together with geodesic models and cylindrical models they offer a rich source of solutions for surface panelization problems.
Polarization vision – a uniform sensory capacity? (2001)

In this concept paper, three scenarios are described in which animals make use of polarized light: the underwater world, the water surface and the terrestrial habitat vaulted by the pattern of polarized light in the sky. Within these various visual environments, polarized light is used in a number of ways that make quite different demands on the neural circuitries mediating these different types of behaviour. Apart from some common receptor and pre-processing mechanisms, the underlying neural mechanisms may differ accordingly. Often, information about chi (the angle of polarization), d (the degree of polarization) and lambda (the spectral content) might not --and need not--be disentangled. Hence, the hypothesis entertained in this account is that polarization vision comes in various guises, and that the answer to the question posed in the title is most probably no.

Magnetic induction and plasma impedance in a planar inductive discharge (1998)

For a planar inductive discharge the magnetic induction components and , the electric field component and the plasma current are calculated from first principles assuming axisymmetric geometry. The mutual inductance M between the primary and secondary circuit, the self-inductance of the plasma and the impedance of the plasma are determined theoretically and related to the properties of the plasma. A global (volume-averaged) discharge model is applied to relate the electron and ion densities and the electron temperature in an argon plasma to the neutral gas pressure and power in the pressure range 2-60 mTorr. The planar inductive discharge is modelled as a transformer with the inductive coil taken as the primary circuit and the plasma as the secondary circuit to find the impedance characteristics in the primary circuit due to the plasma load and the capacitive coupling between the coil and the plasma. The model calculations are compared to measured impedance, rf current and rf voltage, showing fair agreement.
Low cost quartz resonant accelerometer for aircraft inertial navigation (2002)

A low-cost quartz resonator accelerometer was constructed using photolithography to fabricate precision components. The device was tested to establish key resolution, stability, and isolation factors. The cost of the instrument in production volume is expected to be about $200/unit for a performance level of 50 mu g. This accelerometer with appropriate packaging and other minor adaptations can be made suitable for aircraft inertial navigation.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>

Synthesis and Characterization of Novel Poly[(organo)phosphazenes] with Cell-Adhesive Side Groups (2007)

There is a need to develop new scaffold materials with controlled surface properties for tissue engineering applications. For that purpose novel biodegradable poly[(organo)phosphazenes] were synthesized. A cell-binding molecule, galactose, was introduced via a spacer, either 6-aminohexanol (AH) or poly(ethylene glycol) (PEG; M(w) = 3400). Some polymers were substituted with an additional PEG chain of different molecular weights (M(w) = 750 or 5000). The polyphosphazene derivatives were characterized by 1H NMR. T(g) and T(m) were determined using differential scanning calorimetry. A detailed surface analysis of the polymers using X-ray photoelectron spectroscopy (XPS), secondary ion mass spectroscopy (SIMS), and dynamic contact angle (DCA) measurements was performed. Typical backbone and side chain fragments were detected by SIMS and confirmed the polymer composition. Compared to that of the reference polymer (having only amino acid ester side groups), an increased value of the specific ether carbon groups from PEG confirmed the enrichment of PEG at the surface of PEG-Gal polymers. However, the values were lower than expected. DCA studies showed that the galactose moieties were present at the surface after exposure to an aqueous environment. XPS results confirmed the similarity between experimental and theoretical values for the AH-Gal polymers. This indicated the presence of galactose moieties at the surface, which was confirmed by the DCA data because the contact angles were low compared to those of the other polymers.
The Formation and Structure of CVD W Films Produced by the Si Reduction of  WF 6 (1987)

In this paper, we present data on the formation and structure of CVD W films deposited by the Si reduction of . Although the great majority of CVD W films deposited for IC applications are ostensibly deposited by reduction, the Si reduction of always occurs first, even in the presence of copious amounts of . Therefore, it is the Si reduction reaction that determines the nature of W/Si interface, and, in turn, such important properties as contact resistance and leakage current. We have found that Si reduced W films deposited between 210° and 700°C are porous and discontinuous, and are probably not effective barriers to the further diffusion of . The discontinuous structure of the films provides a simple mechanism for the growth of thick W films by Si reduction; such thick films have been observed with increasing frequency as of late and have been enigmatic, because the reaction between and Si was thought to be self‐limiting. An unusual temperature dependence of W film growth is reported. Films deposited below 310°C self‐limit at about coverage (∼60Å of full dense W). In the temperature range 320°–450°C, film coverages up to (∼950Å, at 340°C), are observed. In the higher temperature range, 500°–700°C, film coverages of about (200Å) are observed. The temperature dependence and the self‐limiting behavior of film growth (regardless of the ultimate film thickness at which the film self‐limits), are believed to be controlled by some surface‐catalyzed reaction. Thus, the temperature dependence of the sticking coefficient of a reactive intermediate probably controls the reaction. This kind of model has the potential to explain why minor changes in the Si surface due to cleaning variations, for example, can result in radically different W film growth behavior.
Attributes Scaling for K-means Algorithm Controlled by Misclassification of All Clusters (2010)

K-means clustering is one of the well-known distance-based clustering methods which partitions data into distinct groups. To implement an automatic attribute-scaled K-mean algorithm, the concept of classification has been integrated. Data points which belong to the same target class are considered similar in K-means clustering. In this paper, we explore and determine the optimal attribute-scaled vector that minimizes misclassification error of the target class. This paper uses the non-linear unconstrained optimization technique in attribute-scaled space, called the cyclic coordinate method together with the golden section line search to find the optimal vector. Our experiments show that the methods can provide the optimal scaling vectors which effectively reduce the misclassification error of supervised K-means clustering and lead to the effective supervised clustering in some data sets.
