Innovative Desulfurization Process of Coal Water Slurry under Atmospheric Condition via Sodium Metaborate Electroreduction in the Isolated Slot (2011)

This electrochemical reductive desulfurization (ERD) method for coal water slurry (CWS), which was an offshoot of the research Novel Desulfurization Method of Sodium Borohydride Reduction for Coal Water Slurry (Shen, Y. F.; Sun, T. H.; Jia, J. P. Energy Fuels 2011, 25, 2963–2967.), utilized cathodic reduction to change some chemical compounds into strong reducing substances that convert various forms of sulfur (S) in coal into H2S and S2–, thus releasing S from coals. It was an effective way to enhance S removal from coal by adding divalent metal catalysts (Ni2+, Mn2+, etc.). Using the atmospheric conditions of 12 g/L of NaBO2, 3.0 V of electrolytic voltage, 4 h of electrolytic time, 50 g/L of CWS, ≤140 mesh of coal particle size, 1.0 g/L of NaOH, and 1 mM (about 0.13 g/L) of NiCl2 catalyst, the total sulfur (TS) of CWS can be dramatically reduced by 58.5%. The ERD described here was a predominant desulfurization process, such as mild (slight improvement of the combustion characteristics), high desulfurization efficiency, convenient operation conditions, and low expense (reuse of the filtrate and by-production of hydrogen). Moreover, the realization of the filtrate recycling and the evaluation of the hydrogen releasing rates of NaBH4 were further helpful in cost reduction.
Electrocatalysis of the reduction of organic halide derivatives at modified electrodes coated bycobalt and iron macrocyclic complex-based films: application to the electrochemical determination ofpollutants (2000)

In this study, we go into the examination of the possible use of chemically modified electrodes by Hemin embedded in surfactant film of didodecyldimethylammonium bromide or by electropolymerized cobalt porphyrin and Salen films, as potential materials for the effective electrochemical detection of several organic halides (trichloroacetic acid, ethylene dibromide, tetrachloroethylene, trichloroethylene, dichloroacetic acid, 2,4,6-trichlorophenol, 2,4-dichlorophenoxy acetic acid, methoxychloride, etc.), in aqueous and organic solutions. The reported results show an important catalytic effect induced by the modification of the electrode surface by the metal complexes which is materialized by 1.0 V decrease in the reduction potential of the examined organic halide derivatives and a large increase in their reduction current (2 to 500 times). Our descriptive results of the electrocatalytic behaviour of the examined electrodes constitute a first important step in the investigation of the evaluation of a strategy materializing the use of these modified electrodes for the detection of various significant organohalide derivatives.
OS1212 Comparison of measured residual stress due to welding for butt-welded SUS316 pipe by neutron diffraction measurement and estimation by FEM analysis (2009)

This paper reports measured and estimated results of residual stress distributions of butt-welded austenitic stainless steel pipe in order to improve estimation accuracy of welding residual stress. Neutron diffraction and strain gage method were employed for the measurement of the welding residual stress and its detailed distributions on inner and outer surface of the pipe as well as the distributions within the pipe wall were obtained. Finite element method was employed for the estimation. Transient and residual stresses in 3D butt-welded joint model were computed by employing Iterative Substructure Method and also commercial FEM code ABAQUS for a reference. The measured and estimated distributions presented typical characteristic of straight butt welded pipe which had decreasing trend along the axial direction and bending type distributions through wall of the pipe. Both results were compared and the accuracy of measurement and estimation was discussed.
Adaptive strategy for CPPM single-photon collision avoidance LIDAR against dynamic crosstalk (2017)

Crosstalk is the main challenge for active collision avoidance LIDAR. Conventional strategy on static discrimination threshold and unified number of accumulated pulses is not valid against crosstalk with varying number of sources and varying intensity. This paper presents an adaptive strategy to distinguish the target echo from dynamic crosstalk with unknown intensity in the scenario of intelligent vehicles and autonomous ground vehicles. The adaptive strategy is theoretically and experimentally verified to have much better performance on dynamic crosstalk than conventional strategy, and the detection rate is enhanced by 82.4% as well.
Hydrazine reduction of Np(V) and Pu(IV) (1981)

Np(V) and Pu(IV) in 8M HNO/sub 3/ were reduced by hydrazine at 50/sup 0/C in 1/2 to 2 hours. In 4M and 1.5M HNO/sub 3/, Np(V) reduction by hydrazine was more rapid and complete with a Cu(II) or an Fe(III) ion catalyst.
Incidence of fecal Enterobacteriaceae producing broad-spectrum beta-lactamases in patients with hematological malignancies (2014)

Radiosensitization of Human Leukemic HL-60 Cells by ATR Kinase Inhibitor (VE-821): Phosphoproteomic Analysis (2014)

DNA damaging agents such as ionizing radiation or chemotherapy are frequently used in oncology. DNA damage response (DDR)-triggered by radiation-induced double strand breaks-is orchestrated mainly by three Phosphatidylinositol 3-kinase-related kinases (PIKKs): Ataxia teleangiectasia mutated (ATM), DNA-dependent protein kinase (DNA-PK) and ATM and Rad3-related kinase (ATR). Their activation promotes cell-cycle arrest and facilitates DNA damage repair, resulting in radioresistance. Recently developed specific ATR inhibitor, VE-821 (3-amino-6-(4-(methylsulfonyl)phenyl)-N-phenylpyrazine-2-carboxamide), has been reported to have a significant radio- and chemo-sensitizing effect delimited to cancer cells (largely p53-deficient) without affecting normal cells. In this study, we employed SILAC-based quantitative phosphoproteomics to describe the mechanism of the radiosensitizing effect of VE-821 in human promyelocytic leukemic cells HL-60 (p53-negative). Hydrophilic interaction liquid chromatography (HILIC)-prefractionation with TiO2-enrichment and nano-liquid chromatography-tandem mass spectrometry (LC-MS/MS) analysis revealed 9834 phosphorylation sites. Proteins with differentially up-/down-regulated phosphorylation were mostly localized in the nucleus and were involved in cellular processes such as DDR, all phases of the cell cycle, and cell division. Moreover, sequence motif analysis revealed significant changes in the activities of kinases involved in these processes. Taken together, our data indicates that ATR kinase has multiple roles in response to DNA damage throughout the cell cycle and that its inhibitor VE-821 is a potent radiosensitizing agent for p53-negative HL-60 cells.

New structure for corner compensation in anisotropic KOH etching (1997)

A new compensation layout for the protection of convex corners during anisotropic etching resulting in almost perfectly square corners is presented. The compensation mask design is tested in KOH etching and compared to other compensation designs presented earlier. Advantageous new features are that etching to half of the designed depth of the new corner compensation is geometrically defined and not dependent on KOH concentration - a unique feature - and a high space efficiency, about 20% better than earlier designs for perfect square corners.
Frequency of acoustic myography during isometric contraction of fresh and fatigued muscle and during dynamic contractions (1993)

The frequency of the acoustic myographic (AMG) signal was examined during fresh and fatigued isometric contractions of quadriceps and during dynamic contractions of biceps brachii (BB) in healthy subjects. Recordings were obtained from quadriceps over a range of forces between 10% and 100% maximal voluntary contraction prior to, and 15 minutes after, a fatiguing exercise. Recordings from BB were obtained over a range of submaximal forces (0-8.5 kg) during concentric and eccentric contractions. The mean power frequency (MPF) of the AMG signal was analyzed during each of these contractions by fast-Fourier transform (FFT). The MPF was not significantly different (P > 0.05) during fresh and fatigued contractions of quadriceps and increased quadratically with force in both states (r = 0.81, fresh; r = 0.77, fatigued). During concentric contractions of BB the MPF initially increased with force, but then decreased at the heavier loads (> 5.5 kg). The MPF of eccentric contractions did not significantly (P > 0.05) alter with force. The AMG MPF was within a similar low frequency range for both muscles, during different types of contraction, and was unaltered with fatigue.
A data-driven adaptive iterative learning predictive control for a class of discrete-time nonlinear systems (2010)

On the basis of dynamic linearization method along the iteration axis, a novel data-driven adaptive iterative learning predictive control (AILPC) is presented for a class of general repeatable discrete-time nonlinear systems. The highlight of the algorithm is that the controller design only depends on the I/O data of the dynamical system without using any priori knowledge of the system. The monotonic convergence and effectiveness of the AILPC algorithm are proven and verified through rigorous analyses, numerical example and freeway traffic flow control application.
Aesthetic enhancement of pontic sites for fixed partial dentures. (1998)

The ridge expansion technique using tapered osteotomes can be used anywhere in the maxilla when a change in external ridge morphology would be advantageous for both aesthetics and/or proper dental implant placement. Usually subsequent to tooth loss, the maxilla is generally somewhat undercut in form. This ridge expansion technique can be used to reduce the undercut by bulging out the base of the facial/buccal plate. This would recreate the illusion of root prominences (Figure 12) or permit implant fixtures to be inserted in a more upright position. The tapered osteotomes can therefore predictably be used to expand the buccal bone to simulate the presence of a root prominence for optimal aesthetics for placement of a fixed partial denture prosthesis (Figure 13).
Tailored elliptical holographic diffusers for LCD applications (2005)

Abstract— In this paper, an LCD backlight with holographic diffusers as the top diffuser was investigated. Using a suitable elliptical holographic diffuser, the moiré pattern was eliminated and the brightness of the backlight was increased up to 15% compared to that for a backlight with a conventional diffuser. A Monte Carlo simulation was also applied to compare with the experimental results. In addition, elliptical diffusers can be applied to modify the viewing cone of the backlight.
InP DHBT Single-Stage and Multiplicative Distributed Amplifiers for Ultra- Wideband Amplification (2020)

This paper highlights the gain-bandwidth merit of the single stage distributed amplifier (SSDA) and its derivative multiplicative amplifier topologies (i.e. the cascaded SSDA (C-SSDA) and the matrix SSDA (M-SSDA)), for ultra-wideband amplification. Two new monolithic microwave integrated circuit (MMIC) amplifiers are presented: an SSDA MMIC with 7.1dB average gain and 200GHz bandwidth; and the world's first M-SSDA, which has a 12dB average gain and 170GHz bandwidth. Both amplifiers are based on an Indium Phosphide DHBT process with 250nm emitter width. To the authors best knowledge, the SSDA has the widest bandwidth for any single stage amplifier reported to date. Furthermore, the three tier M-SSDA has the highest bandwidth and gain-bandwidth product for any matrix amplifier reported to date.
Synthetic heparan sulfate ligands for vascular endothelial growth factor to modulate angiogenesis (2021)

We report the discovery of a potential heparan sulfate (HS) ligand to target several growth factors using 13 unique HS tetrasaccharide ligands. By employing an HS microarray and SPR, we deciphered the crucial structure-binding relationship of these glycans with the growth factors BMP2, VEGF<sub>165</sub>, HB-EGF, and FGF2. Notably, GlcNHAc(6-O-SO<sub>3</sub><sup>-</sup>)-IdoA(2-O-SO<sub>3</sub><sup>-</sup>) (HT-2,6S-NAc) tetrasaccharide showed strong binding with the VEGF<sub>165</sub> growth factor. In vitro vascular endothelial cell proliferation, migration and angiogenesis was inhibited in the presence of VEGF<sub>165</sub> and HT-2,6S-NAc or HT-6S-NAc, revealing the potential therapeutic role of these synthetic HS ligands.
Plasma Si nitride—A promising dielectric to achieve high-quality silicon MIS/IL solar cells (1981)

Substantial advantages of plasma Si nitride, for the first time applied to silicon MIS inversion layer (MIS/IL) solar cells, are demonstrated: The highest positive interface charge densities ever used for this type of solar cell (up to 7.2×1012 cm−2), absolute stability of the charges up to the nitride despoition temperature (220 and 300 °C, respectively), excellent passivation of the entire cell, and good AR coating properties. High uv sensitive MIS/IL solar cells were fabricated with these layers on p–Si (100). AM1 efficiencies of 15% (active area) at 25 °C were obtained.
Complete amino acid sequence of goose VLDV‐neurophysin Traces of a putative gene conversion between promesotocin and provasotocin genes (1990)

Goose VLDV-neurophysin (mesotocin-associated neurophysin) has been purified from posterior pituitary glands through molecular sieving on Sephadex G-75 and high-pressure reverse-phase liquid chromatography on Nucleosil C-18 columns. Despite apparent molecular mass of unreduced VLDV-neurophysin measured by polyacrylamide gel electrophoresis with sodium dodecylsulfate appeared near 17 kDa, this value fell to 11 kDa after reduction with mercaptoethanol, suggesting the existence of a homodimer. Complete amino acid sequence (93 residues) of goose VLDV-neurophysin has been determined. N- and C-terminal sequences of the protein have been established by Edman degradation (microsequencing) and use of carboxypeptidase Y, respectively. Peptides derived from oxidized or carboxamidomethylated neurophysin by trypsin or staphylococcal proteinase hydrolyses have been isolated by high-pressure liquid chromatography and microsequenced, allowing determination of the complete sequence. Comparison within the vertebrate VLDV-neurophysin lineage, namely goose VLDV-neurophysin to mammalian VLDV-neurophysins and to deduced toad VLDV-neurophysin, reveals a residue insertion between positions 66 and 67 in the nonmammalian VLDV-neurophysins. When goose MSEL-neurophysin (vasotocin-associated neurophysin) and goose VLDV-neurophysin are compared to their bovine counterparts, identical substitutions are found in positions 17 (Asn in both goose neurophysins instead of Gly in both ox neurophysins), 18 (Arg instead of Lys), 35 (Tyr instead of Phe), and 41 (Thr instead of Ala). Identity of the sequences 10-74 in both ox neurophysins has been explained by partial gene conversion between oxytocin and vasopressin genes, and identical substitutions in both goose neurophysins might reveal a similar gene conversion between mesotocin and vasopressin genes in birds.
Theory of Handwriting (1980)

Handwriting production is viewed as a constrained modulation of an underlying oscillatory process. Coupled oscillations in horizontal and vertical directions produce letter forms, and when superimposed on a rightward constant velocity horizontal sweep result in spatially separated letters. Modulation of the vertical oscillation is responsible for control of letter height, either through altering the frequency or altering the acceleration amplitude. Modulation of the horizontal oscillation is responsible for control of corner shape through altering phase or amplitude. The vertical velocity zero crossing in the velocity space diagram is important from the standpoint of control. Changing the horizontal velocity value at this zero crossing controls corner shape, and such changes can be effected through modifying the horizontal oscillation amplitude and phase. Changing the slope at this zero crossing controls writing slant; this slope depends on the horizontal and vertical velocity zero amplitudes and on the relative phase difference. Letter height modulation is also best applied at the vertical velocity zero crossing to preserve an even baseline. The corner shape and slant constraints completely determine the amplitude and phase relations between the two oscillations. Under these constraints interletter separation is not an independent parameter. This theory applies generally to a number of acceleration oscillation patterns such as sinusoidal, rectangular and trapezoidal oscillations. The oscillation theory also provides an explanation for how handwriting might degenerate with speed. An implementation of the theory in the context of the spring muscle model is developed. Here sinusoidal oscillations arise from a purely mechanical sources; orthogonal antagonistic spring pairs generate particular cycloids depending on the initial conditions. Modulating between cycloids can be achieved by changing the spring zero settings at the appropriate times. Frequency can be modulated either by shifting between coactivation and alternating activation of the antagonistic springs or by presuming variable spring constant springs. An acceleration and position measuring apparatus was developed for measurements of human handwriting. Measurements of human writing are consistent with the oscillation theory. It is shown that the minimum energy movement for the spring muscle is bang-coast-bang. For certain parameter values a singular arc solution can be shown to be minimizing. Experimental measurements however indicate that handwriting is not a minimum energy movement.
Risk Explorer for Software Supply Chains (2022)

Supply chain attacks on open-source projects aim at injecting and spreading malicious code such that it is executed by direct and indirect downstream users. Recent work systematized the knowledge about such attacks and proposed a taxonomy in the form of an attack tree. We propose a visualization tool calledRisk Explorer for Software Supply Chains, which allows inspecting the taxonomy of attack vectors, their descriptions, references to real-world incidents and other literature, as well as information about associated safeguards. Being open-source itself, the community can easily reference new attacks, accommodate for entirely new attack vectors or reflect the development of new safeguards.
Learning models of human movement from video (2005)

Human motion models are of great importance in many application domains. Examples include computer graphics, human-computer interaction, biomechanics, arts and entertainment. 
Traditional approaches to modeling human motion use chains of articulated rigid bodies. These representations approximate single parts of the human body as rigid shapes. Although these models can describe effectively coarse full-body motion, they are unable to represent subtle human movements such as skin deformations, changes in facial expressions or non-rigid torso motion. 
This thesis describes novel representations and methods for capturing 3D models of human body deformations from single-view video without the use of training data or any prior geometric model. Strong geometric constraints are shown to derive from the proposed non-rigid 3D shape representations. These constraints are used in two ways: first, to disambiguate the 2D motion of feature points in visual tracking; second, to reconstruct non-rigid 3D shape from the estimated 2D motion in the image sequence. The proposed methods are closely related to generic machine learning algorithms, such as factor analysis, probabilistic principal component analysis and identification of linear dynamical systems. The algorithms are demonstrated on challenging video sequences of non-rigid human motion under severe cases of occlusion and variable illumination.
