A Comprehensive Survey on Three-Dimensional (2008)

Three-dimensional(3-D)meshes havebeenusedmore and more in industrial, medical and entertainment applications during the last decade. Many researchers, from both the academic and the industrial sectors, have become aware of their intellectual propertyprotectionandauthenticationproblemsarisingwiththeir increasing use. This paper gives a comprehensive survey on 3-D mesh watermarking, which is considered an effective solution to the above two emerging problems. Our survey covers an introduc- tion to the relevant state of the art, an attack-centric investigation, and a list of existing problems and potential solutions. First, the particular difficulties encountered while applying watermarking on 3-D meshes are discussed. Then we give a presentation and an analysis of the existing algorithms by distinguishing them between fragile techniques and robust techniques. Since attacks play an im- portant role in the design of 3-D mesh watermarking algorithms, we also provide an attack-centric viewpoint of this state of the art. Finally, some future working directions are pointed out especially on the ways of devising robust and blind algorithms and on some new probably promising watermarking feature spaces.
Effective finite-difference modelling methods with 2-D acoustic wave equation using a combination of cross and rhombus stencils (2016)

The 2-D acoustic wave equation is commonly solved numerically by finite-difference (FD) methods in which the accuracy of solution is significantly affected by the FD stencils. The commonly used cross stencil can reach either only second-order accuracy for space domain dispersion-relation-based FD method or (2&lt;it&gt;M&lt;/it&gt;)th-order accuracy along eight specific propagation directions for time–space domain dispersion-relation-based FD method, if the conventional (2&lt;it&gt;M&lt;/it&gt;)th-order spatial FD and second-order temporal FD are used to discretize the equation. One other newly developed rhombus stencil can reach arbitrary even-order accuracy. However, this stencil adds significantly to computational cost when the operator length is large. To achieve a balance between the solution accuracy and efficiency, we develop a new FD stencil to solve the 2-D acoustic wave equation. This stencil is a combination of the cross stencil and rhombus stencil. A cross stencil with an operator length parameter &lt;it&gt;M&lt;/it&gt; is used to approximate the spatial partial derivatives while a rhombus stencil with an operator length parameter &lt;it&gt;N&lt;/it&gt; together with the conventional second-order temporal FD is employed in approximating the temporal partial derivatives. Using this stencil, a new FD scheme is developed; we demonstrate that this scheme can reach (2&lt;it&gt;M&lt;/it&gt;)th-order accuracy in space and (2&lt;it&gt;N&lt;/it&gt;)th-order accuracy in time when spatial FD coefficients and temporal FD coefficients are derived from respective dispersion relation using Taylor-series expansion (TE) method. To further increase the accuracy, we derive the FD coefficients by employing the time–space domain dispersion relation of this FD scheme using TE. We also use least-squares (LS) optimization method to reduce dispersion at high wavenumbers. Dispersion analysis, stability analysis and modelling examples demonstrate that our new scheme has greater accuracy and better stability than conventional FD schemes, and thus can adopt large time steps. To reduce the extra computational cost resulting from adopting the new stencil, we apply the variable spatial operator length schemes. Adopting our new FD scheme, characterized by new stencil, LS-based optimization, variable operator lengths and larger time step, modelling efficiency is significantly improved.
Quantitative Analysis of Endovenous Laser Ablation based on Human Vein Optical Properties (2011)

Endovenous laser ablation (EVLA) is a common treatment method for varicose vein. However, the precise irradiation dose for EVLA is not understood quantitatively. The objective of this study is to evaluate EVLA quantitatively based on optical properties of the varicose vein tissue, and compare the efficacy and the safety at wavelengths of 980 nm and 1470 nm. A human varicose vein tissue was used as a sample. The samples were irradiated by using the 980 nm and 1470 nm laser diodes in various irradiation parameters. The power density was varied from 260 to 1710 W/cm2 and the irradiation time was varied from 3 to 10 s. The optical properties of samples were determined by using a double integrating sphere and an inverse Monte Carlo method. The optical penetration depth of samples was estimated from the optical properties. In the 980 nm laser irradiation, the initial shrinkage of the tissue was observed during laser irradiation conducted at the average energy density of 3630 J/cm2 (1210 W/cm2, 3 s). In the 1470 nm laser irradiation, the initial shrinkage of the tissue was observed during laser irradiation conducted at the average energy density of 2600 J/cm2 (260 W/cm2, 10 s). Penetration depth of the vein wall at the wavelength of 980 nm and 1470 nm were 1.3 mm and 0.22 mm, respectively. The sample irradiated with the 1470 nm laser diode showed vein shrinkage in lower energy density than the 980 nm laser irradiation. The penetration depth at the wavelength of 1470 nm was smaller than the sample thickness about 0.8 mm. These data indicate that EVLA with the 1470 nm laser diode may be more effective and safer than EVLA with the 980 nm laser diode.
On-chip single photon filtering and multiplexing in hybrid quantum photonic circuits (2017)

Quantum light plays a pivotal role in modern science and future photonic applications. Since the advent of integrated quantum nanophotonics different material platforms based on III-V nanostructures-, colour centers-, and nonlinear waveguides as on-chip light sources have been investigated. Each platform has unique advantages and limitations; however, all implementations face major challenges with filtering of individual quantum states, scalable integration, deterministic multiplexing of selected quantum emitters, and on-chip excitation suppression. Here we overcome all of these challenges with a hybrid and scalable approach, where single III-V quantum emitters are positioned and deterministically integrated in a complementary metal-oxide-semiconductor-compatible photonic circuit. We demonstrate reconfigurable on-chip single-photon filtering and wavelength division multiplexing with a foot print one million times smaller than similar table-top approaches, while offering excitation suppression of more than 95 dB and efficient routing of single photons over a bandwidth of 40 nm. Our work marks an important step to harvest quantum optical technologies' full potential.Combining different integration platforms on the same chip is currently one of the main challenges for quantum technologies. Here, Elshaari et al. show III-V Quantum Dots embedded in nanowires operating in a CMOS compatible circuit, with controlled on-chip filtering and tunable routing.
Evaluation of Membrane Permeability of Rat brain Using Diffusion Magnetic Resonance Imaging (2008)

We propose a method of non-invasively evaluating the permeability of cell membranes in normal rat brain using diffusion magnetic resonance imaging (MRI). Diffusion MRI signals reflect the intra- and extracellular diffusion coefficients of water molecules in permeable biological tissues and cell membranes. The signals were acquired using a 4.7 T MRI system and applying a motion-probing gradient (MPG) in six directions. Numerical simulations using the finite-difference method were conducted for various combinations of intracellular diffusion coefficients and cell-membrane permeabilities. We defined the evaluative function as the difference between the signals from numerical simulations and experimentally obtained signals. We found that the minimum value for the evaluative function enabled us to estimate the intracellular diffusion coefficient and membrane permeability of the rat brain, which were corresponded to (1.3±0.1) × 10-3 mm2/sec and 66±24 μm/sec. Our method was useful for non-invasively estimating the cell-membrane permeability of biological tissues, and can easily be applied to human tissues and other samples.
Hidden Markov model analysis of manufacturing process information (2002)

A method is presented for using hidden Markov models (HMMs) for the analysis of force, torque, and position signals from sensors in manufacturing machines. The HMM can detect the transitions between contact states and compute a measure of the task quality using a model of the task developed by the manufacturing engineer and optimized on training data. The HMM method has been evaluated in extensive experimentation with teleoperation and the results suggest even higher effectiveness in automation and manufacturing applications.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
PyTouch: A Machine Learning Library for Touch Processing (2021)

With the increased availability of rich tactile sensors, there is an an equally proportional need for open-source and integrated software capable of efficiently and effectively processing raw touch measurements into high-level signals that can be used for control and decision-making. In this paper, we present PyTouch – the first machine learning library dedicated to the processing of touch sensing signals. PyTouch, is designed to be modular, easy-to-use and provides state-of-the-art touch processing capabilities as a service with the goal of unifying the tactile sensing community by providing a library for building scalable, proven, and performance-validated modules over which applications and research can be built upon. We evaluate PyTouch on real-world data from several tactile sensors on touch processing tasks such as touch detection, slip and object pose estimations. PyTouch is open-sourced at https://github.com/facebookresearch/pytouch.
Biphasic energy selection for transthoracic cardioversion of atrial fibrillation. The BEST AF Trial (2007)

First-shock success was significantly higher, particularly in patients with a BMI >25 kg/m(2), when a non-escalating initial 200 J energy was selected. The overall success, duration of procedure and amount of sedation administered, however, did not differ significantly between the two protocols.
A novel dual-gate high electron mobility transistor using a split-gate structure (1997)

The split-gate concept has been applied to dual-gate high electron mobility structures for room-temperature operation. The gates are configured so that the second gate is in close proximity to the gap defined by the split-gate electrodes. This allows both gates to control the carrier density in the same region of the device, so that it is possible to control the threshold voltage for either gate by altering the bias at which the other gate is held. The effect of changing the gate configuration is demonstrated.

Prediction of repetitive firing behaviour from voltage clamp data on an isolated neurone soma (1971)

1. Membrane parameters of an isolated neural cell body have been determined by voltage clamp analysis. Data are expressed as membrane ion-specific conductances, leak conductance, and capacitance.2. Three ionic currents are present: Inward, I(I); and two operationally distinct outward currents, I(K) and I(A). Both outward currents are apparently carried by potassium ions.3. Hodgkin-Huxley-like equations were solved for the discharge of two sequential action potentials in response to a constant stimulus current. The digital computer solutions are compared with action potential data recorded from the investigated cell.4. The computed and experimentally measured relationships between firing frequency and stimulus current intensity are compared and are linear over the same portion of the total frequency range.5. Cell behaviour in the latter part of the interspike interval is dominated by the conductance g(A) while g(Na) and g(K) largely determine the character of the action potential and the initial portion of the interspike interval.6. Prehyperpolarization of the membrane activates g(A) and the membrane response to depolarizing current differs markedly from the response elicited when no prehyperpolarization is imposed.
Management of acute anemia in a Jehovah's Witness patient with acute lymphoblastic leukemia with polymerized bovine hemoglobin‐based oxygen carrier: a case report and review of literature (2010)

This report documents the successful management of profound anemia in an acute leukemia patient who refused blood transfusion, with the use of Hemopure, to save the patient from the devastating effects of ischemia associated with severe anemia. Hemopure may represent a life-saving intervention in patients with severe symptomatic anemia when blood transfusion is not an option.
Renal P450 Metabolites of Arachidonic Acid and the Development of Hypertension in Dahl Salt-Sensitive Rats (1997)

Renal transplantation studies indicate that some form of renal dysfunction underlies the development of hypertension in Dahl salt-sensitive (S) rats; however, the factors responsible for altering kidney function remain to be determined. Previous studies have indicated that Dahl S rats require a higher renal perfusion pressure to excrete the same amount of sodium and water as normotensive rats and that this is due largely to an elevation in Cl- transport in the thick ascending limb of the loop of Henle. There are now five lines of evidence that suggest an abnormality in the renal metabolism of arachidonic acid by enzymes of the P4504A family may contribute to the increase in loop Cl- transport and the development of hypertension in Dahl S rats. In this regard, the formation of 20-HETE and the levels of P4504A protein are reduced in the outer medulla of Dahl S rats. Perfusion of the loop of Henle of Dahl S rats with exogenous 20-HETE normalizes the elevated loop Cl- transport. In addition, a genetic marker in the P4504A2 gene, which encodes for the enzyme that makes 20-HETE, cosegregates with the development of hypertension in an F2 cross of Dahl S and Lewis rats. Finally, induction of renal production of 20-HETE with clofibrate prevents the development of hypertension in Dahl S rats and inhibition of renal 20-HETE formation produces hypertension in Lewis rats fed a high salt diet. These results implicate the CYP4A2 locus as a candidate gene that contributes to the alterations in renal function and the development of hypertension in Dahl S rats.
Effect of Induction-Hardened Depth on Torsional Fatigue Strength of Notched Specimens. (1996)

The effect of induction-hardened depth on torsional fatigue strength of notched specimens were investigated. The results are as follows. (1) Induction-hardened specimens shows the best torsional fatigue strength when the effective case depth / radius ratio is about 0.5. (2) In the case ofshallow case depth, the cracks initiate at the hardened / unhardened bound-ary. On the other hand, the fracture ofdeeply hardened specimen originates from the surface
Fabrication of Large-Diameter Single-Crystal Silicon Aspheric Lens by Straight-Line Enveloping Diamond-Turning Method. (2002)

The conventional method for aspheric surface diamond turning is the arc-enveloping method. In the present study, a new method termed the straight-line enveloping method is proposed, in which the aspheric surface is generated using a straight-nosed diamond tool on a three-axis simultaneous control ultraprecision machine tool. This method is preferable to the conventional method for the machining of convex aspheric surfaces on hard brittle materials since it significantly improves efficiency and lowers tool wear. The experimental setup configuration and the tool setting method are described and the formation of form error is analyzed. An aspheric lens having 1.36μm form error and 78nmR ysurface roughness was obtained on a 120mm diameter single-crystal silicon substrate at a tool feed rate of 20μm/rev. by applying the proposed method.

eBooks with indexes that reorganize conceptually (2004)

Subject indexes were an important step forward for books because they enabled the comparison and correlations of information without extensive reading, re-reading and memorization. In this short paper, we focus on the user interaction and usage scenario of a new system called ScentIndex that enhances the subject index of an eBook by conceptually reorganizing it to suit particular information needs. Users first enter information needs via keywords describing the concepts they are trying to retrieve and comprehend. ScentIndex then computes what index entries are conceptually related, and reorganizes and displays these index entries on a single page.
Measurement of basal cerebral perfusion and metabolic activity in LDLr −/− ;hApoB +/+ mice (2011)

The aim of this study was to investigate the feasibility of using positron emission tomography (PET) imaging with readily available radiotracers to assess the effect of atherosclerosis on basal cerebral perfusion and metabolic activity in mice. 13 NH 3 and 18 FDG were selected since the former is widely used for the measurement of myocardial perfusion and the latter is a known marker of cellular glucose metabolism, including in the brain. Adult 12 month‐old male C57Bl/6 mice (n=3) and LDLr −/− ApoB +/+ mice (n=7) with established atherosclerosis were used. The uptake of 13 NH 3 and 18 FDG was measured in both the cortex and the center of the brain. PET images showed consistent higher (30%, p≤0.0001) cerebral 13 NH 3 uptake that was associated with higher (10%, p≤0.001) cerebral 18 FDG uptake in atherosclerotic mice. These data validate the use of PET imaging to measure basal cerebral perfusion and brain metabolic activity in mice. In addition, they suggest that atherosclerosis is associated with higher cerebral perfusion and increased glucose uptake that could reflect hypoxia associated with atherosclerosis, since chronic hypoxia is known to increase brain capillary density and glucose transport across the blood‐brain barrier leading to an enhanced brain 18 FDG uptake. Supported by CIHR (MOP 89733).

Strategies for overcoming temporary phytotoxic effects of calcium sulfite applied to agricultural soils (1994)

Calcium sulfite is a major component of scrubber residues produced by lime-based flue gas desulfurization (FGD) processes, widely used in the Ohio River Valley. Preliminary studies have shown that calcium sulfite severely decreased corn plant growth when incorporated into acid soils at moderate rates. Evidence is strong that the toxic effect on plant growth is due to generation of sulfur dioxide in acidic soil. Bioassay methods were used to demonstrate that raising soil pH reduced calcium sulfite toxicity. In solution and in soils, calcium sulfite oxidizes to calcium sulfate (gypsum), which is an agricultural soil amendment useful for increasing calcium levels in acidic subsoils. This potential for oxidation indicates the possibility of incorporating calcium sulfite several months before the crop is sown so that the calcium sulfite will transform to gypsum, which should, because of its relatively high solubility, leach below the plow layer and improve the subsoil.
