The paper considers the emergence of industrial robots and quotes a number of relevant examples. These robost are then classified in four ways depending on their mode of construction. Practical parameters for choosing industrial robots are then studied. This is followed by a section dealing with remote control devices. This study is extended with the aim of classifiyng robots in acordance with their task and potentials . Intelligents machines are given some attention. Retturning to the industrial scene, the author describes avaible and also still missing qualities of robots. The paper concludes with a description of recent developments.
Note: Electro-optic coefficients of Li-deficient MgO-doped LiNbO3 crystal (2016)

A number of Li-deficient MgO-doped LiNbO<sub>3</sub> (LN) crystals with different Li<sub>2</sub>O contents ranging from 43.4 mol. % to 44.5 mol. % were prepared by carrying out the Li-poor vapor transport equilibration treatment on 5 mol. % (in growth melt) MgO-doped LN crystals. Unclamped electro-optic (EO) coefficients γ<sub>13</sub> and γ<sub>33</sub> of these crystals were measured by Mach-Zehnder interferometry. The results show that γ<sub>13</sub> (γ<sub>33</sub>) increases linearly by ∼14% (11%) as the Li<sub>2</sub>O content decreases from 44.5 mol. % of the as-grown state to 43.4 mol. % of the Li-deficient state. This feature is desired for the EO application of the Li-deficient MgO:LN crystal.
Partial volume effect in quantitative magnetic resonance perfusion imaging (2005)

In dynamic-susceptibility contrast (DSC) magnetic resonance (MR) perfusion imaging, the cerebral blood flow (CBF) is estimated from the tissue residue function obtained through deconvolution of the contrast concentration functions. However, the reliability of CBF estimates obtained by deconvolution is sensitive to various distortions. Among the most prominent experimental limitations is the image spatial resolution, leading to partial volume effect (PVE), which arises when the size of the voxel exceeds the volume containing the arterial input signal. PVE results in distortion of the arterial input function (AIF), and directly leads to miscalculation of the CBF. This work demonstrates the degree of the CBF estimation bias that could develop as a result of PVE.

<title>Orthogonal and biorthogonal multiwavelets for signal denoising and image compression</title> (1998)

This paper presents new vector filter banks, in particular biorthogonal Hermite cubic multiwavelets with short, smooth duals. We study different preprocessing techniques and the covariance structure of corresponding transforms. Results of numerical experiments in signal denoising and image compression using multi-filters are discussed.We compare the performance of several multi-filters with the performance of standard scalar wavelets such as Daubechies orthogonal external phase and least asymmetric ones and biorthogonal 9- 7 pair. Often multiwavelet scheme turn out to be better. We analyze these results.

Leveraging probabilistic season and location context models for scene understanding (2008)

Recent research has shown the power of context-aware scene understanding in bridging the semantic gap between high-level semantic concepts and low-level image features. In this paper, we present a new method to exploit nonvisual context information from the season and location proximity in which pictures were taken to facilitate region (object) annotation in consumer photos. Our method does not require precise time and location from the capture device or user input. Instead, it learns from rough location (e.g., states in the US) and time (e.g., seasons) information, which can be obtained through picture metadata automatically or through minimal user input (e.g., grouping). In addition, the visual context within the image is obtained by analyzing the spatial relationships between different regions (objects) in the scene. Both visual and nonvisual context information are fused using a probabilistic graphical model to improve the accuracy of object region recognition. Our method has been evaluated on a database that consists of over 10,000 regions in more than 1000 images collected from both the Web and consumers. Experimental results show that incorporating the season and location context significantly improves the performance of region recognition.
Active devices for microwave distributed amplification (1990)

Abstract The theoretical results presented in this letter demonstrate the possibility of growing waves' propagation along MESFET electrodes, through a distributed interaction mechanism based on the active characteristics of the transistor. The analysis proves that a T cross‐section gate is necessary to obtain amplification, moreover this gate configuration allows a remarkable reduction of the electrode gate resistance. In the validity range of the analysis used, the main feature of the new device is a wide bandwidth, deriving from a fully distributed component. This device could result in a valid substitute for low power TWTs.
The effect of a Foul Release coating on propeller performance (2002)

With the imminent ban on the application of coatings of TBT self-polishing co-polymers in January 2003 and their eventual prohibition in 2008 a great deal of research is being conducted into the performance of the possible alternatives. As part of the ongoing work investigating the hydrodynamic performance of foul release systems, being carried out at the University of Newcastle upon Tyne, a study into the possible benefits of their use on propellers has been conducted. The benefits that this method of propeller protection offers are potential fuel savings from increased propulsive efficiency as well as lower maintenance costs and a cleaner environment. Initially a literature review exploring the effect of propeller surface conditions on ship performance and previous work on propeller coatings for merchant ships was conducted. Theoretical calculations on the possible gains were then explored for a merchant ship propeller type using a propeller lifting surface analysis program. These showed that the significant losses in efficiency caused by blade roughening can be avoided by the application of a foul release coating with a surface finish equivalent to a new or well polished propeller.
Monte Carlo simulation of secondary electron images for real sample structures in scanning electron microscopy (2011)

Monte Carlo simulation methods for the study of electron beam interaction with solids have been mostly concerned with specimens of simple geometry. In this article, we propose a simulation algorithm for treating arbitrary complex structures in a real sample. The method is based on a finite element triangular mesh modeling of sample geometry and a space subdivision for accelerating simulation. Simulation of secondary electron image in scanning electron microscopy has been performed for gold particles on a carbon substrate. Comparison of the simulation result with an experiment image confirms that this method is effective to model complex morphology of a real sample.
Purification and Characterization of a Catalase from the Facultatively Psychrophilic Bacterium <i>Vibrio rumoiensis</i> S-1 <sup>T</sup> Exhibiting High Catalase Activity (2000)

Catalase from the facultatively psychrophilic bacterium Vibrio rumoiensis S-1(T), which was isolated from an environment exposed to H(2)O(2) and exhibited high catalase activity, was purified and characterized, and its localization in the cell was determined. Its molecular mass was 230 kDa, and the molecule consisted of four identical subunits. The enzyme, which was not apparently reduced by dithionite, showed a Soret peak at 406 nm in a resting state. The catalytic activity was 527,500 U. mg of protein(-1) under standard reaction conditions at 40 degrees C, 1.5 and 4.3 times faster, respectively, than those of the Micrococcus luteus and bovine catalases examined under the same reaction conditions, and showed a broad optimum pH range (pH 6 to 10). The catalase from strain S-1(T) is located not only in the cytoplasmic space but also in the periplasmic space. There is little difference in the activation energy for the activity between strain S-1(T) catalase and M. luteus and bovine liver catalases. The thermoinstability of the activity of the former catalase were significantly higher than those of the latter catalases. The thermoinstability suggests that the catalase from strain S-1(T) should be categorized as a psychrophilic enzyme. Although the catalase from strain S-1(T) is classified as a mammal type catalase, it exhibits the unique enzymatic properties of high intensity of enzymatic activity and thermoinstability. The results obtained suggest that these unique properties of the enzyme are in accordance with the environmental conditions under which the microorganism lives.
Initiating levodopa/carbidopa therapy with and without entacapone in early Parkinson disease: The STRIDE‐PD study (2010)

Initiating L-dopa therapy with LCE failed to delay the time of onset or reduce the frequency of dyskinesia compared to LC. In fact, LCE was associated with a shorter time to onset and increased frequency of dyskinesia compared to LC. These results may reflect that the treatment protocol employed did not provide continuous L-dopa availability and the higher L-dopa dose equivalents in the LCE group.
A ceramic capacitive pressure microsensor with screen-printed diaphragm (2005)

In this work, a ceramic capacitive sealed gauge pressure sensor has been designed, fabricated, and fully characterized for harsh environment pressure microsensor applications. Thick film screen printing has been expanded as a method for creating ceramic microstructures. The ceramic pressure microsensor consists of a bottom electrode deposited on a 96% alumina substrate and a top electrode deposited on a ceramic diaphragm. The ceramic cavity and diaphragm were created using a thick film sacrificial layer. Hermeticity of the pressure sensor was characterized to assess the sensor's feasibility for MEMS applications such as harsh environment sealed gauge pressure sensors. The sensor showed excellent hermeticity with a maximum leak rate of 7.0 times 10 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">-10</sup> atm cc/sec He after exposures to temperatures up to 500 degC. The sensor was also fully characterized up to 300 degC in a pressure range of 0 to 50 psi. The average sensitivity over these temperature and pressure ranges was 9.2 fF/psi
Effect of Cilostazol on the P50 of the Oxygen-Hemoglobin Dissociation Curve (2014)

Cilostazol is a drug used for the treatment of intermittent claudication caused by narrowing of the blood vessels and reduced oxygen supply, characterized by intense pain in the leg when walking. This study was designed to investigate the effect of cilostazol on the P50 of the oxygen hemoglobin dissociation curve. A total of eight healthy adult subjects were studied. Blood samples (0.5 mL) from each subject were mixed with 5, 10, and 20 μL of the 0.5 mg/mL stock solution of cilostazol to give concentrations of 10, 20, and 40 µg/mL equivalent to adult doses of 50, 100, and 200 mg, respectively. The control sample had no drug added. The oxygen hemoglobin dissociation curve of each sample was plotted and the P50 determined with a Hemox-Analyzer (TCS, Medical Products Division, Southampton, PA). The mean P50 for the control samples was 28.27 ± 0.43 mm Hg. The values of the samples exposed to 10, 20, and 40 µg/mL cilostozol were 29.63 ± 0.66, 30.15 ± 0.77, and 31.66 ± 0.62 mm Hg, respectively. There was a statistically significant difference (p < 0.01) between the control and samples exposed to 40 µg/mL cilostazol. This study suggests that cilostazol caused an increase in the release of oxygen from hemoglobin as shown in the P50 values. This effect was significant at the highest concentration of 40 µg/mL.
Dimethyl Fumarate and Its Esters: A Drug with Broad Clinical Utility? (2020)

Fumaric acid esters (FAEs) are small molecules with anti-oxidative, anti-inflammatory and immune-modulating effects. Dimethyl fumarate (DMF) is the best characterised FAE and is approved and registered for the treatment of psoriasis and Relapsing-Remitting Multiple Sclerosis (RRMS). Psoriasis and RRMS share an immune-mediated aetiology, driven by severe inflammation and oxidative stress. DMF, as well as monomethyl fumarate and diroximel fumarate, are commonly prescribed first-line agents with favourable safety and efficacy profiles. The potential benefits of FAEs against other diseases that appear pathogenically different but share the pathologies of oxidative stress and inflammation are currently investigated.
Inlet Water Quality Forecasting of Wastewater Treatment Based on Kernel Principal Component Analysis and an Extreme Learning Machine (2018)

The stable operation of sewage treatment is of great significance to controlling regional water environment pollution. It is also important to forecast the inlet water quality accurately, which may ensure the purification efficiency of sewage treatment at a low cost. In this paper, a combined kernel principal component analysis (KPCA) and extreme learning machine (ELM) model is established to forecast the inlet water quality of sewage treatment. Specifically, KPCA is employed for feature extraction and dimensionality reduction of the inlet wastewater quality and ELM is utilized for the future inlet water quality forecasting. The experimental results indicated that the KPCA-ELM model has a higher accuracy than the other comparison PCA-ELM model, ELM model, and back propagation neural network (BPNN) model for forecasting COD and BOD concentration of the inlet wastewater, with mean absolute error (MAE) values of 2.322 mg/L and 1.125 mg/L, mean absolute percentage error (MAPE) values of 1.223% and 1.321%, and root mean square error (RMSE) values of 3.108 and 1.340, respectively. It is recommended from this research that the method may provide a reliable and effective reference for forecasting the water quality of sewage treatment.
Probing Crystal Growth of ε- and α-CL-20 Polymorphs via Metastable Phase Transition Using Microscopy and Vibrational Spectroscopy (2014)

This article presents evidence of a possible route to the formation of ε- and α-polymorphic phases of 2,4,6,8,10,12-hexanitro-2,4,6,8,10,12-hexaazaisowurtzitane (CL-20) studied through CL-20 solution using a reverse and normal precipitation method. Reverse precipitation with instant addition facilitated the opportunity to track the crystal phases from their immediate formation to the end of phase stabilization. Precipitation under apparent conditions to achieve α- or ε-phases showed the initial occurrence of a metastable β-phase and subsequent transformation to the intended stable phases. The β-phase showed sufficiently longer stability while under specified conditions for ε- than in a hydrated medium set to obtain the α-phase. Transformation of fine needle-shaped β-CL-20 crystals to uniform diamond-shaped α- or bipyramidal ε-habit had been observed to pass through an equilibrium state of dissolution and reprecipitation. This work also elaborates the effect of crystallization methodology on conversion time. Vibrational spectroscopy and microscopic techniques were employed to track time-dependent polymorphic conversions. A drastic reduction in β → ε conversion time, from 160 to 10 min, could have been affected by using ultradispersed seed crystals. We thus also demonstrated a hazard free nongrinding method to prepare ε-CL-20 with particle size < 10 μm through precipitation and their effect on thermal stability and mechanical sensitivity.
A twisted-bundle layout structure for minimizing inductive coupling noise (2000)

In this paper, we propose a novel twisted-bundle layout structure for minimizing inductive coupling noise. In this structure, we create several routing regions and re-order the routing of nets in each of these routing regions. The purpose is to create complementary and opposite current loops in the twisted-bundle layout structure, such that the magnetic fluxes arising from any signal net within a twisted group cancel each other in the current loop of a net of interest. The effectiveness of the twisted-bundle structure in minimizing coupling inductance has been verified by the application of FastHenry extraction on a 16-bit bus structure. We achieve about two orders of magnitude reduction in inductive coupling. SPICE simulations also show that the 16-bit twisted-bundle bus structure is able to maintain high signal integrity at high frequency of operation.

Matriptase Is Highly up-Regulated in Chronic Lymphocytic Leukemia and Promotes Cancer Cell Invasion (2012)

Abstract Abstract 4612 Proteases are known to play a critical role in cancer development and progression. Matriptase is an epithelial transmembrane serine protease essential for skin development and barrier function. Matriptase overexpression has been reported in many human solid tumors including prostate, breast, ovarian, kidney and lung cancers, indicating that matriptase may play an important role in cancer. In mice, dysregulated matriptase activity promotes malignant transformation and carcinogenesis. In human blood, low levels of matriptase mRNA expression were detected in monocytes and B-lymphocytes but the biological significance is unclear. In this study, we examined matriptase mRNA and protein expression in 15 hematological cancer cell lines and 223 bone marrow samples from patients with leukemia by reverse transcription PCR (RT-PCR), quantitative real-time PCR (qRT-PCR) and Western blotting. Flow cytometry and immunostaining were used to determine the cell membrane expression of matriptase in B cell-derived Namalwa cells and bone marrow cells from leukemia patients. Small hairpin RNA (shRNA) interference and a recombinant matriptase inhibitor, hepatocyte growth factor activator inhibitor (HAI)-1, were used to inhibit matriptase expression and activity in Namalwa, Raji and chronic lymphocytic leukemia (CLL) cells to test the effect of matriptase inhibition on cancer cell invasion in matrigel-based assays. Our results showed that matriptase mRNA was highly expressed in Namalwa and Raji cells and in bone marrow cells from patients with CLL. Such an expression profile was not found in bone marrow cells from patients with acute lymphocytic leukemia (ALL), acute myeloid leukemia (AML) and chronic myeloid leukemia (CML). By Western blotting, matriptase protein expression was confirmed in bone marrow samples from the majority (79/81, 97.5%) of CLL patients. By immunostaining and flow cytometry, matriptase protein was localized on the surface of Namalwa and CLL cells. In these cells, the matriptase inhibitors, HAI-1 and HAI-2, were not detected, indicating that the upregulated matriptase activity may not be inhibited in CLL cells. In functional studies, silencing matriptase gene expression by specific shRNAs markedly reduced Namalwa and Raji cells and bone marrow cells from CLL patients in invading matrigels. Similarly, a recombinant HAI-1 dose-dependently inhibited matrigel invasion of these cancer cells. In conclusion, our results showed that matriptase was highly expressed on the surface of CLL cells. Inhibition of matriptase by gene silencing or specific inhibitor prevented CLL cells in invading matrigels, indicating that matriptase contributes to the invasiveness of the cancer cells. Our results suggest that matriptase may represent a new cell surface marker for CLL and that blocking matriptase expression or activity may be used as a therapeutic strategy to inhibit CLL progression.

Context-Aware Commodity Recommendation Information Service in E-commerce (2012)

It is difficult for users to acquire personal commodity information in E-commerce services. In order to solve the problem, we propose a methodology to enhance the ease of obtain such information. This paper develops a framework for e-commerce services. The framework is based on information context awareness. The core component of this framework or architecture is facilitated by combining the ontology model of enterprise-product information and user (client) context ontology model. Thought such mechanism and advanced algorithm, a mapping relationship between two ontology models can be developed, thus a hybrid model and implement settling can be built and it through the well-defined prototype named Context-aware Commodity Recommendation Information Service (CACRIS).
