Surface Recognition and Speed Adjustment of Humanoid Robot Using External Control Circuit (2020)

We propose a surface-recognition-based speed- adjustment system for humanoid robot during walking on different surfaces. Two different types of surfaces are considered in the reported experiment (example, rough and smooth surface). Force-sensors, classification unit and external- controller-circuits are applied for surface-recognition and speed-adjustment. For surface-recognition the Euclidean distance is used to calculate the nearest-neighbor reference pattern for the feature of the waking pattern generated online. The mean-absolute-value (MAV) feature vector is used to classify two different surfaces. To distinguish two different surfaces, the hardware accelerated decision-signals are generated across LEDs in the form of analog voltages (maximum peak voltage 212 mV for rough-surface and 147 mV for smooth surfaces respectively with detection time 2.8 s and 1.5 s). The external-controller-circuit is used for speed- adjustment using decision-signal coming from LED. It is observed that, when robot is moving from rough-surfaces to smooth-surfaces, the speed of the robot motion changes from 190 frames/stride (i.e. slow-speed) to 160 frames/stride (i.e. medium-speed) with 4.9 s transition time, whereas from smooth- surface to rough-surface transitions, the transition time takes 4.5 s. The experimentally measurement results of speed- adjustment time after surface transition are useful for fast and stable recognition-system design.
Effect of different levels of dietary vitamin E (dl-α-tocopherol acetate) on the occurrence of various degrees of white striping on broiler breast fillets (2012)

White striping could be a potential reason for the rejection of raw breast fillets in the market. The condition is characterized grossly by the white striations occurring on the fillets showing myopathic changes on microscopic examination. Early research has shown similar lesions in the case of nutritional muscular dystrophy, which is a condition caused mainly by the deficiency of vitamin E in the diet. The present study was intended to evaluate the effect of different levels of dietary vitamin E (dl-α-tocopherol acetate) on the incidence of normal, moderate, and severe degrees of white striping, by modern description, on broiler breast fillets. Basal diets adequate for starter (0 to 18 d), grower (19 to 32 d), and finisher (33 to 49 d) age periods supplemented with 15, 50, 100, 200, and 400 IU of vitamin E/kg of feed were used in the study. Each of the 5 diet treatments were fed to 8 pens (53 birds each) of male broilers from a commercial strain. At 49 d, 5 birds were randomly selected from each pen (n = 40 birds/diet treatment) and were processed. Live weight, ready-to-cook weight, weight of the fillets, wings, tenders, legs, and the racks were obtained. The fillets were scored for the 3 degrees of white striping. There were no significant differences among the diet treatments with respect to the weight and carcass yield parameters. Furthermore, the diet treatments did not show any significant effect on the occurrence of normal, moderate, and severe degrees of white striping. However, fillet weight was the only parameter that had a significant effect on the occurrence of white striping. Higher degrees of white striping were seen associated with heavier fillets, which is in accordance with previous studies. Different levels of vitamin E levels used in the present study did not show any significant effect on the occurrence of 3 degrees of white striping. These results suggest that dietary vitamin E level is not associated with the modern condition of white striping in broiler breast meat.
Evidence That Antibiotics Bind to Human Mitochondrial Ribosomal RNA Has Implications for Aminoglycoside Toxicity (2015)

Aminoglycosides are a well known antibiotic family used to treat bacterial infections in humans and animals, but which can be toxic. By binding to the decoding site of helix44 of the small subunit RNA of the bacterial ribosome, the aminoglycoside antibiotics inhibit protein synthesis, cause misreading, or obstruct peptidyl-tRNA translocation. Although aminoglycosides bind helix69 of the bacterial large subunit RNA as well, little is known about their interaction with the homologous human helix69. To probe the role this binding event plays in toxicity, changes to thermal stability, base stacking, and conformation upon aminoglycoside binding to the human cytoplasmic helix69 were compared with those of the human mitochondrial and Escherichia coli helix69. Surprisingly, binding of gentamicin and kanamycin A to the chemically synthesized terminal hairpins of the human cytoplasmic, human mitochondrial, and E. coli helix69 revealed similar dissociation constants (1.3-1.7 and 4.0-5.4 μM, respectively). In addition, aminoglycoside binding enhanced conformational stability of the human mitochondrial helix69 by increasing base stacking. Proton one-dimensional and two-dimensional NMR suggested significant and specific conformational changes of human mitochondrial and E. coli helix69 upon aminoglycoside binding, as compared with human cytoplasmic helix69. The conformational changes and similar aminoglycoside binding affinities observed for human mitochondrial helix69 and E. coli helix69, as well as the increase in structural stability shown for the former, suggest that this binding event is important to understanding aminoglycoside toxicity.
Combo HD-DVD and DVD pickup head with prisms (2005)

We proposed a combo design of pick-up head used prism to shorten the geometrical size and reduce the optical components. We apply a rhomboid beam splitter to separate two diodes in the design for the optical pick-up head of DVD and HD-DVD.
GENERALIZATION OF FEATURES IN THE ASSEMBLY NEURAL NETWORKS (2004)

The purpose of the paper is an experimental study of the formation of class descriptions, taking place during learning, in assembly neural networks. The assembly neural network is artificially partitioned into several sub-networks according to the number of classes that the network has to recognize. The features extracted from input data are represented in neural column structures of the sub-networks. Hebbian neural assemblies are formed in the column structure of the sub-networks by weight adaptation. A specific class description is formed in each sub-network of the assembly neural network due to intersections between the neural assemblies. The process of formation of class descriptions in the sub-networks is interpreted as feature generalization. A set of special experiments is performed to study this process, on a task of character recognition using the MNIST database.
Characterization of Nitrosoalkane Binding and Activation of Soluble Guanylate Cyclase (2005)

Soluble guanylate cyclase (sGC) is the primary receptor for the signaling agent nitric oxide (NO). Electronic absorption and resonance Raman spectroscopy were used to show that nitrosoalkanes bind to the heme of sGC to form six-coordinate, low-spin complexes. In the sGC-nitrosopentane complex, a band assigned to an Fe-N stretching vibration is observed at 543 cm(-)(1) which is similar to values reported for other six-coordinate NO-bound hemoproteins. Nitrosoalkanes activate sGC 2-6-fold and synergize with YC-1, a synthetic benzylindazole derivative, to activate the enzyme 11-47-fold. In addition, the observed off-rates of nitrosoalkanes from sGC were found to be dependent on the alkyl chain length. A linear correlation was found between the observed off-rates and the alkyl chain length which suggests that the sGC heme has a large hydrophobic distal ligand-binding pocket. Together, these data show that nitrosoalkanes are a novel class of heme-based sGC activators and suggest that heme ligation is a general requirement for YC-1 synergism.
Antifertility effects of tetradecyl sodium sulphate in rabbits (1983)

Acrosin and acrosomal hyaluronidase were inhibited by tetradecyl sodium sulphate (TDSS) in vitro at concentrations of less than 10(-4) M. TDSS prevented the removal in vitro of the cumulus oophorus by testicular hyaluronidase and the zona pellucida by acrosin. TDSS had a contraceptive effect in rabbits when administered intravaginally before coitus or released at levels of 1-3 micrograms/day from intrauterine silicone rubber devices.
Optical Properties of GaN/AlN(0001) Quantum Dots Grown by Plasma-Assisted Molecular Beam Epitaxy (2006)

We have investigated the Ga-flux dependence of growth morphology and optical properties of GaN quantum dots (QDs) in AlN(0001). The QDs formed either by Stranski–Krastanov (S–K) or autosurfactant modified S–K growth depending on the incident Ga-flux during rf-plasma assisted molecular beam epitaxy. We correlated reflection high-energy electron diffraction specular intensity transients to the QD dimensions measured by atomic force microscopy. Single QD layers with growth mode dependant size, density, and wetting layer thickness were characterized by room temperature photoluminescence (PL) with a pulsed 193 nm excitation source. We used a self-consistent one-dimensional Schrödinger–Poisson calculation to identify the contribution of wetting layer quantum wells (1–4 monolayer GaN) and QDs in the PL spectra.
Strained Bottlebrushes in Super-Soft Physical Networks (2019)

ABA triblock copolymers composed of a poly(dimethylsiloxane) (PDMS) bottlebrush central block and linear poly(methyl methacrylate) (PMMA) terminal blocks self-assemble into a physical network of PDMS bottlebrush strands connected by PMMA spherical domains. A combination of small- and ultrasmall-angle X-ray scattering techniques was used to concurrently examine dimensions of PMMA spherical domains and PDMS bottlebrush strands both in the bulk and at the PMMA-PDMS interface. In agreement with scaling model predictions, the degrees of polymerization of the bottlebrush backbone (<i>n</i><sub>bb</sub>) and PMMA block (<i>n</i><sub>A</sub>) correlate with the measured PMMA domain size and area per molecule at the PMMA-PDMS interface as <i>D</i><sub>A</sub> ∝ (<i>n</i><sub>bb</sub><i>n</i><sub>A</sub>)<sup>1/3</sup> and <i>S</i> ∝ <i>n</i><sub>A</sub><sup>2/3</sup><i>n</i><sub>bb</sub><sup>-1/3</sup>, respectively. In the bulk, bottlebrush strands are extended due to steric repulsion between the side chains and unfavorable interactions between the different blocks. At the PMMA-PDMS interface with large curvature, packing constraints require additional bottlebrush backbone extension and alignment of side chains along the backbone in the direction perpendicular to the interface.
Comparison of the efficacy of endoscopic tympanoplasty and microscopic tympanoplasty: A systematic review and meta‐analysis (2016)

Patients receiving endoscopic tympanoplasty have a lower canalplasty rate and more desirable cosmetic result than do those receiving microscopic tympanoplasty. Laryngoscope, 127:1890-1896, 2017.
Continuous mapping for road map assisted localization (2009)

Abstract – Robust localization is a fundamental com-ponent of autonomous vehicles. In that context essen-tial information has to be provided by a sufficient se-lection of sensor observations. In case of land-based road-constrained motion a map offers significant infor-mation and assists localization with valuable informa-tion about the evolution of the kinematic vehicle states. Throughout this proposal cubic spline curves are chosen to approximate the true motion constraints, e.g. roads or tracks, and the vehicle kinematics are modelled in one-dimensional curve coordinates. The resulting map-to-vehicle relation enables a straight forward derivation of measurement update equations and offers itself to classical filter techniques. Incoming sensor measure-ments are used for a simultaneous vehicle localization and a local road map update around the current vehicle position. Moreover map-extrapolation is carried out to handle situations with incomplete maps. The proposed method is validated with simulations and within a real railway scenario.

A ful12D and 3D TCAD Simulation ofultimate 22nm NAND Flash Memories (2009)

In this paper we propose a way to study the ultimate technological node for Flash cell described in the International Technology Roadmap for Semiconductors (ITRS), corresponding to the 22nm feature size. We have first developed a 2D TCAD simulation of a 4-bit-NAND string based on classical microelectronics recipes, to validate the whole process conditions. To check the good behavior of our processed cells, we first evaluate the programmed and erased threshold voltages by electrically simulating the Drain Current versus Control Gate Voltage. Then we also investigate the impact of the short space between neighbor cells on disturb between cells inside the NAND string. We have developed a 3D TCAD simulation of a 3x3 array, based on the previous 2D process simulation, in order to extract the values of parasitic capacitances, disturbing the whole functioning of the array.
Removal of PCR Error Products and Unincorporated Primers by Metal-Chelate Affinity Chromatography (2011)

Immobilized Metal Affinity Chromatography (IMAC) has been used for decades to purify proteins on the basis of amino acid content, especially surface-exposed histidines and "histidine tags" genetically added to recombinant proteins. We and others have extended the use of IMAC to purification of nucleic acids via interactions with the nucleotide bases, especially purines, of single-stranded RNA and DNA. We also have demonstrated the purification of plasmid DNA from contaminating genomic DNA by IMAC capture of selectively-denatured genomic DNA. Here we describe an efficient method of purifying PCR products by specifically removing error products, excess primers, and unincorporated dNTPs from PCR product mixtures using flow-through metal-chelate affinity adsorption. By flowing a PCR product mixture through a Cu(2+)-iminodiacetic acid (IDA) agarose spin column, 94-99% of the dNTPs and nearly all the primers can be removed. Many of the error products commonly formed by Taq polymerase also are removed. Sequencing of the IMAC-processed PCR product gave base-calling accuracy comparable to that obtained with a commercial PCR product purification method. The results show that IMAC matrices (specifically Cu(2+)-IDA agarose) can be used for the purification of PCR products. Due to the generality of the base-specific mechanism of adsorption, IMAC matrices may also be used in the purification of oligonucleotides, cDNA, mRNA and micro RNAs.

Accessibility Devices for Mobile Interfaces Extensions (2015)

The development of mobile applications that consider accessibility can uniquely make use of software extensions to provide special interfaces to people with impairments. However, such extensions are limited so that the use of external devices is a natural alternative. The current market provides several accessibility devices that can be coupled to mobile devices, extending their interface abilities. However, there is not a work that compares such devices and assists the job of developers in finding an adequate device in accordance with their needs. Considering this scenario, this paper analyzed 60 scientific articles and over 250 relevant sites to identify devices that facilitate the use of applications running on mobile operating systems for impaired people. At the final of the process, 15 products were analyzed and compared against predefined features. Apart the number of existing devices for accessibility, it is possible to conclude that the market is still requiring a higher variety of options and further researches to provide a better level of accessibility for impaired users.
A Blue Organic Light Emitting Diode (1999)

A blue organic light emitting diode (OLED) which has a structure like an SH-B type diode has been developed. The blue OLED consists of a hole-injection layer (m-MTDATA), a hole-transporting emissive layer, a hole-blocking layer and an electron-injection layer (Alq 3 ) formed on an ITO anode by vacuum vapor deposition. α-NPD was used for the hole-transporting emissive layer, which has an emission peak at around 455 nm. For the hole-blocking layer, we found that 2,9-Dimethyl-4,7-diphenyl-1,10-phenanthroline (Bathocuproine) is a very effective material. As Bathocuproine has a good hole-blocking ability, the recombination area is in the α-NPD layer. The electroluminescence peak from the new blue OLED is at around 455 nm. The color coordinate in CIE chromaticity is (0.15, 0.16). The blue OLED has a potential of over 10,000 cd/m 2 at 9.5 V under DC operation with an AlLi cathode. When this OLED is driven under a 1/100 duty ratio, the peak luminance is over 54,000 cd/m 2 . The luminous efficiency was 1.1 lm/W at 150 cd/m 2 . The blue OLED device is also a good green device without the Bathocuproine layer. The green OLED shows electroluminescence from the Alq 3 layer with luminance of 40,000 cd/m 2 at 10 V under DC operation, and the color coordinate in CIE chromaticity is (0.33, 0.55).
The NIKA2 Sunyaev-Zeldovich Large Program: Precise galaxy cluster physics for an accurate cluster-based cosmology (2022)

The NIKA2 Guaranteed-Time SZ Large Program (LPSZ) is dedicated to the high-angular resolution SZ mapping of a representative sample of 45 SZ-selected galaxy clusters drawn from the catalogues of the Planck satellite, or of the Atacama Cosmology Telescope. The LPSZ sample spans a mass range from 3 to 11 × 10 14 M ⊙ and a redshift range from 0:5 to 0:9, extending to higher redshift and lower mass the previous samples dedicated to the cluster mass calibration and universal properties estimation. The main goals of the LPSZ are the measurement of the average radial profile of the ICM pressure up to R 500 by combining NIKA2 with Planck or ACT data, and the estimation of the scaling law between the SZ observable and the mass using NIKA2, XMM-Newton and Planck/ACT data. Furthermore, combining LPSZ data with existing or forthcoming public data in lensing, optical/NIR or radio domains, we will build a consistent picture of the cluster physics and further gain knowledge on the mass estimate as a function of the cluster morphology and dynamical state. We give an overview of the LPSZ, present recent results and discuss the future implication for cosmology with galaxy clusters.
In2S3 Atomic Layer Deposition and Its Application as a Sensitizer on TiO2 Nanotube Arrays for Solar Energy Conversion (2010)

In2S3 atomic layer deposition (ALD) with indium acetylacetonate (In(acac)3) and H2S was studied with quartz crystal microbalance (QCM), X-ray reflectivity (XRR), and Fourier transform infrared (FTIR) spectroscopy techniques. Subsequent In2S3 ALD on TiO2 nanotube arrays defined a model semiconductor sensitized solar cell. For In2S3 ALD on initial Al2O3 ALD surfaces, the In2S3 ALD displayed a nucleation period of ∼60−70 cycles followed by a linear growth region. These results were obtained under ALD conditions that were not completely self-limiting for the In(acac)3 exposure because of the low In(acac)3 vapor pressure. The growth per cycle decreased at higher temperature over the temperature range from 130 to 170 °C at these same reactant conditions. The growth per cycle was 0.30−0.35 Å per cycle at 150 °C as determined by QCM and XRR measurements at higher In(acac)3 exposures where the surface reactions were self-limiting chemistry versus In(acac)3 and H2S exposures. The FTIR examinations revealed that the nucleation period on Al2O3 ALD surfaces may be related to the formation of Al(acac)* species that act to poison the initial Al2O3 ALD surface. X-ray diffraction investigations revealed β-In2S3 ALD films and X-ray photoelectron measurements were consistent with In2S3 films. The In2S3 ALD was employed as a semiconductor sensitizer on TiO2 nanotube arrays for solar conversion. Scanning electron microscopy and energy dispersive X-ray analysis imaging revealed In2S3 over the full length of the TiO2 nanotube array after 175 cycles of In2S3 ALD at 150 °C at reactant exposure conditions that were self-limiting on flat substrates. The photoelectrochemical properties of these In2S3 ALD-sensitized TiO2 nanotube arrays with a Co2+/Co3+ electrolyte were then characterized by measuring the photocurrent density versus voltage and the external quantum efficiency versus photon energy. A small quantum efficiency of ∼10% was observed that can be attributed to charge recombination losses and charge injection/collection processes.

Rapid reaction of MoS2 nanosheets with Pb2+ and Pb4+ ions in solution (2017)

Understanding the chemical changes happening to nanostructures during a process is vital in selecting them for applications. Here, we investigated the difference in the reactivity of the bulk and nanoscale forms of molybdenum disulfide (MoS<sub>2</sub>) in solution with lead ions (Pb<sup>2+</sup> and Pb<sup>4+</sup>) as probes, at room temperature. While the bulk form did not show any reactivity in the experimental timescale, the two-dimensional (2D) nanoscale form showed not only reactivity but also quite rapid kinetics that resulted in the formation of distinct products, principally PbMoO<sub>4</sub> with anion substitution, in a few seconds. Depending on the charge state of the cation, and the pH of the reaction mixture, two different kinds of morphologies of the same reaction product were formed. Furthermore, we demonstrate that this unusual reactivity of the MoS<sub>2</sub> nanosheets (NSs) was retained in its supported form and hence, such supported materials can be effective for the abstraction of toxic lead from water, with fast kinetics.
First observation of the decay Λb0→ηc(1S)pK− (2020)

The decay ${\mathrm{\ensuremath{\Lambda}}}_{b}^{0}\ensuremath{\rightarrow}{\ensuremath{\eta}}_{c}(1S)p{K}^{\ensuremath{-}}$ is observed for the first time using a data sample of proton-proton collisions, corresponding to an integrated luminosity of $5.5\text{ }\text{ }{\mathrm{fb}}^{\ensuremath{-}1}$, collected with the LHCb experiment at a center-of-mass energy of 13 TeV. The branching fraction of the decay is measured, using the ${\mathrm{\ensuremath{\Lambda}}}_{b}^{0}\ensuremath{\rightarrow}J/\ensuremath{\psi}p{K}^{\ensuremath{-}}$ decay as a normalization mode, to be $\mathcal{B}({\mathrm{\ensuremath{\Lambda}}}_{b}^{0}\ensuremath{\rightarrow}{\ensuremath{\eta}}_{c}(1S)p{K}^{\ensuremath{-}})=(1.06\ifmmode\pm\else\textpm\fi{}0.16\ifmmode\pm\else\textpm\fi{}0.0{6}_{\ensuremath{-}0.19}^{+0.22})\ifmmode\times\else\texttimes\fi{}{10}^{\ensuremath{-}4}$, where the quoted uncertainties are statistical, systematic and due to external inputs, respectively. A study of the ${\ensuremath{\eta}}_{c}(1S)p$ mass spectrum is performed to search for the ${P}_{c}(4312{)}^{+}$ pentaquark state. No evidence is observed and an upper limit of $\frac{\mathcal{B}({\mathrm{\ensuremath{\Lambda}}}_{b}^{0}\ensuremath{\rightarrow}{P}_{c}(4312{)}^{+}{K}^{\ensuremath{-}})\ifmmode\times\else\texttimes\fi{}\mathcal{B}({P}_{c}(4312{)}^{+}\ensuremath{\rightarrow}{\ensuremath{\eta}}_{c}(1S)p)}{\mathcal{B}({\mathrm{\ensuremath{\Lambda}}}_{b}^{0}\ensuremath{\rightarrow}{\ensuremath{\eta}}_{c}(1S)p{K}^{\ensuremath{-}})}&lt;0.24$ is obtained at the 95% confidence level.
