Effects of the growth parameters on the hydrothermal synthesis of ZnO nano-rods and their application to GaN based LEDs (2017)

Accurate growth control is required to apply ZnO nanorods to devices and materials. This study examined the effects of the growth parameters, such as pressure, growth temperature, growth time, and concentration of the growth solution. The pressure had little influence on ZnO growth. The growth temperature increased length of ZnO nanorods but not affected diameter of ZnO nanorods. The concentration of the growth solution increased the length and diameter of ZnO nanorods. The growth time affected only length of the ZnO nanorods. We confirmed the effect of ZnO nanorods growth parameters successfully and control is possible. The LEDs with ZnO nanorods exhibited improved light extraction efficiency due to the wave manipulation by the ZnO nanorods.

Ultrafine Highly Magnetic Fluorescent γ-Fe2O3/NCD Nanocomposites for Neuronal Manipulations (2018)

In this work, we describe a low-cost, two-step synthesis of composites of nitrogen-doped carbon quantum dots (NCDs) with γ-Fe<sub>2</sub>O<sub>3</sub> (NCDs/γ-Fe<sub>2</sub>O<sub>3</sub>), which is based on a hydrothermal cum co-precipitation method. The product is a fine powder of particles having an average diameter of 9 ± 3 nm. The physical and chemical properties of NCDs/γ-Fe<sub>2</sub>O<sub>3</sub> were studied, as well as the superconducting quantum interference device and Mossbauer analysis of the magnetic properties of these nanocomposites. The interaction of NCDs/γ-Fe<sub>2</sub>O<sub>3</sub> nanocomposites with neuron-like cells was examined, showing efficient uptake and low toxicity. Our research demonstrates the use of the nanocomposites for imaging and for controlling the cellular motility. The NCDs/γ-Fe<sub>2</sub>O<sub>3</sub> nanocomposites are promising because of their biocompatibility, photostability, and potential selective affinity, paving the way for multifunctional biomedical applications.

A non-filamentary model for unipolar switching transition metal oxide resistance random access memories (2011)

A model for resistance random access memory (RRAM) is proposed. The RRAM under research utilizes certain transition metal oxide (TMO) such as NiO which shows unipolar switching behavior. The existence of metal/insulator states is not explained by filaments but attributed to different Hubbard U values, which stems from an electron correlation effect. Current-voltage formulae are given both on the metal and insulator sides by putting the appropriate solutions of Hubbard model into the mesoscopic Meir-Wingreen transport equation. The RESET phenomenon is explained by a sufficient separation of Fermi levels in the electrodes and hence a Mott transition can be triggered in the anodic region due to a lack of electrons. The SET behavior originates from a tunneling current which removes the insulating region near the anode. Several experimental evidences are also presented to support this model. The model also serves as the theoretical prototype of Correlated Electron Random Access Memory (CeRAM) which is defined to be a TMO RRAM whose working mechanism is based on the strong electron correlation effects.
The heterogeneous chemical kinetics of NO3 on atmospheric mineral dust surrogates (2005)

Uptake experiments of NO3 on mineral dust powder were carried out under continuous molecular flow conditions at 298 +/- 2 K using the thermal decomposition of N2O5 as NO3 source. In situ laser detection using resonance enhanced multiphoton ionization (REMPI) to specifically detect NO2 and NO in the presence of N2O5, NO3 and HNO3 was employed in addition to beam-sampling mass spectrometry. At [NO3] = (7.0 +/- 1.0) x 10(11) cm(-3) we found a steady state uptake coefficient gamma(ss) ranging from (3.4 +/- 1.6) x 10(-2) for natural limestone to (0.12 +/- 0.08) for Saharan Dust with gamma(ss) decreasing as [NO3] increased. NO3 adsorbed on mineral dust leads to uptake of NO2 in an Eley-Rideal mechanism that usually is not taken up in the absence of NO3. The disappearance of NO3 was in part accompanied by the formation of N2O5 and HNO3 in the presence of NO2. NO3 uptake performed on small amounts of Kaolinite and CaCO3 leads to formation of some N2O5 according to NO((3ads)) + NO(2(g)) --> N2O(5(ads)) --> N2O(5(g)). Slow formation of gas phase HNO3 on Kaolinite, CaCO3, Arizona Test Dust and natural limestone has also been observed and is clearly related to the presence of adsorbed water involved in the heterogeneous hydrolysis of N2O(5(ads)).
A wavelet transform for atrial fibrillation Cycle Length measurements (2009)

We describe a new algorithm for the estimation of Cycle Lengths (CL) in the atria. In the spirit of wavelet transforms, the algorithm correlates the electrogram (EGM) signal to a set of functions that are specifically designed to extract the cycle length present in the signal on a given time window. This provides a CL vs time map, which is a highly informative representation of the electrical activation of the tissue. Subsequently, the information from this map is compressed into a histogram that unravels the distribution of the dominant CLs.. Finally, a sliding window tracks automatically the changes in CLs over a larger time scale. Results on both synthetic and real data are presented. The correlation with known cycle lengths in the synthetic cases is strong, and the CL distributions on real data are similar to those obtained from manually annotated EGMs. 1.
Segmentation based denoising using multiple compaction domains (2003)

In this paper, we propose a novel segmentation based denoising algorithm. Segmentation yields intrinsically homogeneous and extrinsically heterogeneous regions. A denoising algorithm that uses Multiple Compaction Domains (MCD) is then applied on each of the resulting segments. Such a scheme retains important perceptual information in the segment boundaries while the denoising algorithm operates only on homogeneous segments. Further, the MCD algorithm is demonstrably superior to the classical denoising algorithms using transform domain thresholding. Our algorithm yields better perceptual quality and superior PSNR as compared to MATLAB's adaptive Wiener filter.
Final Report on Advanced Research in Range Image Interpretation for Automated Mail Handling (1990)

We discuss an implemented software system that interprets dense range images obtained from scenes of heaps of postal pieces: letter, parcels, etc. We describe a model-based system consisting of segmentation, modeling, and classification procedures.\nFirst, the range image is segmented into regions and reasoning is done about the physical support of these regions. Second, for each region several possible 3-D interpretations are made based on the partial knowledge which is updated whenever a new interpretation is obtained. Finally each interpretation is tested against the data for its consistency.\nWe have chosen the superquadric model as our 3-D shape descriptor, plus deformations such as tapering and bending along the major axis. The superquadric model is an analytic representation of volume for which a cross-section is one of a class of curves varying between rectangular to elliptical shaped. Superquadric parameters are recovered by minimizing the least-squares error between the superquadric surface and the range data. The system recovers p position, orientation, shape, size and class of the object. Using the goodness of fit and Euclidean distance measures, and the shape and size parameters of the recovered model, objects are classified into one of the following broad categories: flat (letters), box (parcels), roll (circular and elliptical cylinders), and irregular (film mailers etc.).\nThe overall approach to this problem has been to find the most general yet computationally economical method to interpret the data. Experimental results obtained from a large number of complex range images are reported.

A Practical Asymmetric Synthesis of Isopropyl (1R,2S)-Dehydrocoronamate (2011)

A novel asymmetric synthesis of isopropyl (1R,2S)-dehydrocoronamate is described from (S)-1,2,4-butanetriol as the starting material in 28% overall yield. Highlights of this synthetic route include selective cyclopropanation between chiral cyclic sulfate 5 and diisopropyl malonate (8c), formation of vinylcyclopropane 3c via elimination of halide 4c, selective monohydrolysis of diisopropyl ester 3c, and Curtius rearrangement of acid 10 to form isopropyl (1R,2S)-dehydrocoronamate TsOH salt 13 in >99% ee. With the involvement of only three isolations, this chromatography-free process provides a rapid and practical access to (1R,2S)-1-amino-2-vinylcyclopropane-1-carboxylic acid derivatives.
Role of Interleukin-5 in Local Accumulation of Eosinophils in Mouse Allergic Peritonitis (1991)

The injection of ragweed pollen extracts into the peritoneal cavity of actively immunized mice caused an accumulation of eosinophils in the cavity. We investigated the role of interleukin-5 (IL-5), one of the T-cell-derived factors, in this in vivo local accumulation. Ciclosporin, an immunosuppressant that mainly suppresses T cell functions, dose-dependently inhibited the in vivo local accumulation. Injections of the neutralizing antibody to IL-5 into the cavity decreased the number of the accumulating eosinophils. When the peritoneal cells of the immunized mice were cultured in the presence of the antigen in vitro, IL-5 activity was detected in the culture supernatant. The results indicate that IL-5 plays an important role in the in vivo local accumulation of eosinophils after an antigen challenge.
Time-reversal in a waveguide (2001)

Experimental evidence of time-reversal has been performed at an ultrasonic scale (1.5–3.5 MHz) in a 70 long cm, 1 cm deep waveguide. This laboratory experiment allow us to get rid of noise or ocean fluctuations classically observed. Spatial and temporal time-focusing are studied and interpreted by the method of images in a waveguide or matched-field theory. For a wide band source array, an algorithm based on time-reversal is presented to achieve depth and range shifting without any knowledge of the waveguide properties.
Optomechanical fiber gyroscope (2009)

We report a miniature mechanical gyroscope that utilizes optical means to detect rotation-induced displacements in a mechanical structure. It utilizes the Foucault pendulum principle used in some existing MEMS gyroscopes: a rotating reference frame induces a Coriolis force that oscillates the structure about an axis orthogonal to the driving-mode axis. The main difference with similar MEMS gyroscopes is that this rotation-induced oscillation is sensed using a pair of high-finesse fiber Fabry-Perot displacement sensors instead of a capacitive device. The drive axis is also driven by radiation pressure inside a set of auxiliary fiber Fabry-Perot cavities, making this device immune to electromagnetic interference. Calculations predict that a rotation sensitivity on the order of 1°/h/Hz<sup>1/2</sup> is achievable. We show that this structure solves several problems associated with MEMS gyroscopes utilizing electrostatic sensing methods.
Cse1l Is Essential for Early Embryonic Growth and Development (2001)

The CSE1L gene, the human homologue of the yeast chromosome segregation gene CSE1, is a nuclear transport factor that plays a role in proliferation as well as in apoptosis. CSE1 and CSE1L are essential genes in Saccharomyces cerevisiae and mammalian cells, as shown by conditional yeast mutants and mammalian cell culture experiments with antisense-mediated depletion of CSE1L. To analyze whether CSE1L is also essential in vivo and whether its absence can be compensated for by other genes or mechanisms, we have cloned the murine CSE1L gene (Cse1l) and analyzed its tissue- and development-specific expression: Cse1l was detected at embryonic day 7.0 (E7.0), E11.0, E15.0, and E17.0, and in adults, high expression was observed in proliferating tissues. Subsequently, we inactivated the Cse1l gene in embryonic stem cells to generate heterozygous and homozygous knockout mice. Mice heterozygous for Cse1l appear normal and are fertile. However, no homozygous pups were born after interbreeding of heterozygous mice. In 30 heterozygote interbreeding experiments, 50 Cse1l wild-type mice and 100 heterozygotes were born but no animal with both Cse1l alleles deleted was born. Embryo analyses showed that homozygous mutant embryos were already disorganized and degenerated by E5.5. This implicates with high significance (P < 0.0001, Pearson chi-square test) an embryonically lethal phenotype of homozygous murine CSE1 deficiency and suggests that Cse1l plays a critical role in early embryonic development.
In situ measurement of the viscoelastic modulus of gels using pure twist-theory (2012)

We propose a simple method to measure the viscoelasticity of hydrogels. Our method is based on twisting a flat-ended circular indenter on a thin layer of gel. Since poroelastic flow is suppressed under pure shear, such a method allows direct and separate measurement of the solid gel network's viscoelastic properties. A potential advantage of this method is that it is possible to carry it out in situ, e.g. under cell culture conditions, and with high-throughput. We use the correspondence principle to determine the relationship between the applied torque and the history of twist by solving an elasticity problem. A solution is obtained using the finite element and Hankel transform methods. The relation between the applied torque and the history of twist can be expressed in a simple closed-form expression involving the relaxation function of the gel, the thickness of the gel layer and the indenter radius.
Multifunctional catheters combining intracardiac ultrasound imaging and electrophysiology sensing (2008)

A family of 3 multifunctional intracardiac imaging and electrophysiology (EP) mapping catheters has been in development to help guide diagnostic and therapeutic intracardiac EP procedures. The catheter tip on the first device includes a 7.5 MHz, 64-element, side-looking phased array for high resolution sector scanning. The second device is a forward-looking catheter with a 24-element 14 MHz phased array. Both of these catheters operate on a commercial imaging system with standard software. Multiple EP mapping sensors were mounted as ring electrodes near the arrays for electrocardiographic synchronization of ultrasound images and used for unique integration with EP mapping technologies. To help establish the catheters' ability for integration with EP interventional procedures, tests were performed in vivo in a porcine animal model to demonstrate both useful intracardiac echocardiographic (ICE) visualization and simultaneous 3-D positional information using integrated electroanatomical mapping techniques. The catheters also performed well in high frame rate imaging, color flow imaging, and strain rate imaging of atrial and ventricular structures. The companion paper of this work discusses the catheter design of the side-looking catheter with special attention to acoustic lens design. The third device in development is a 10 MHz forward-looking ring array that is to be mounted at the distal tip of a 9F catheter to permit use of the available catheter lumen for adjunctive therapy tools.
Fault-tolerant drive-by-wire systems (2002)

The article begins with a review of electronic driver assisting systems such as ABS, traction control, electronic stability control, and brake assistant. We then review drive-by-wire systems with and without mechanical backup. Drive-by-wire systems consist of an operating unit with an electrical output, haptic feedback to the driver, bus systems, microcomputers, power electronics, and electrical actuators. For their design safety, integrity methods such as reliability, fault tree and hazard analysis, and risk classification are required. Different fault-tolerance principles with various forms of redundancy are considered, resulting in fail-operational, fail-silent, and fail-safe systems. Fault-detection methods are discussed for use in low-cost components, followed by a review of principles for fault-tolerant design of sensors, actuators, and communication. We evaluate these methods and principles and show how they can be applied to low-cost automotive components and drive-by-wire systems. A brake-by-wire system with electronic pedal and electric brakes is then considered in more detail, showing the design of the components and the overall architecture. Finally, we present conclusions and an outlook for further development of drive-by-wire systems.

Toward real-time endoscopically-guided robotic navigation based on a 3D virtual surgical field model (2015)

The challenge is to accurately guide the surgical tool within the three-dimensional (3D) surgical field for robotically-assisted operations such as tumor margin removal from a debulked brain tumor cavity. The proposed technique is 3D image-guided surgical navigation based on matching intraoperative video frames to a 3D virtual model of the surgical field. A small laser-scanning endoscopic camera was attached to a mock minimally-invasive surgical tool that was manipulated toward a region of interest (residual tumor) within a phantom of a debulked brain tumor. Video frames from the endoscope provided features that were matched to the 3D virtual model, which were reconstructed earlier by raster scanning over the surgical field. Camera pose (position and orientation) is recovered by implementing a constrained bundle adjustment algorithm. Navigational error during the approach to fluorescence target (residual tumor) is determined by comparing the calculated camera pose to the measured camera pose using a micro-positioning stage. From these preliminary results, computation efficiency of the algorithm in MATLAB code is near real-time (2.5 sec for each estimation of pose), which can be improved by implementation in C++. Error analysis produced 3-mm distance error and 2.5 degree of orientation error on average. The sources of these errors come from 1) inaccuracy of the 3D virtual model, generated on a calibrated RAVEN robotic platform with stereo tracking; 2) inaccuracy of endoscope intrinsic parameters, such as focal length; and 3) any endoscopic image distortion from scanning irregularities. This work demonstrates feasibility of micro-camera 3D guidance of a robotic surgical tool.

Degradation of Trichloroethylene by Methanol-Grown Cultures of Methylosinus trichosporium OB3b PP358 (1996)

A soluble methane monooxygenase-constitutive mutant strain of Methylosinus trichosporium OB3b, strain PP358, was grown with methanol as the carbon source, and the kinetics of trichloroethylene (TCE) degradation were determined. PP358 exhibited high TCE degradation rates under both oxygen- and carbon-limiting conditions. The optimal pseudo first-order rate constant for TCE was comparable to the values measured for cells grown with methane. We found that growth under oxygen-limiting conditions results in increased accumulation of polyhydroxybutyrate, which in turn correlates with higher transformation capacities for TCE. It was also shown that methanol inhibits TCE degradation only at high concentrations. Thus, methanol-grown cultures of PP358 represent an efficient system for the biodegradation of chlorinated hydrocarbons.
