Epitaxial growth of SrCaTiO3 films on GaN by molecular beam epitaxy with a TiO2 buffer layer (2020)

We demonstrate the epitaxial growth of (111)-oriented Sr1 − xCaxTiO3 (SCTO) thin films on (0002) GaN using a thin (100) TiO2 buffer layer by RF-plasma-assisted oxide molecular beam epitaxy. We explore the growth window of SCTO for both x = 0 (i.e., SrTiO3) and x = 0.24 with various TiO2 buffer layer thicknesses and find that a substrate temperature of 650 °C and TiO2 thickness of 1 nm produce the highest quality films, as determined by reflection high energy electron diffraction, x-ray diffraction, and atomic force microscopy. SCTO films deposited without a buffer layer are polycrystalline, confirming the necessity of the TiO2 buffer layer to facilitate (111)-oriented epitaxial growth of SCTO on GaN. Transmission electron microscopy performed on the samples shows that the SCTO films grown with a TiO2 buffer layer are highly textured, and selected-area electron diffraction patterns indicate that some domains in the oxide exhibit cation ordering along the (111) direction. We also show that the growth mode changes from 2D to 3D as the thickness of SCTO increases past 10 nm, which leads to film relaxation and a rougher surface morphology.
Formation of the Peroxisome Lumen Is Abolished by Loss of <i>Pichia pastoris</i> Pas7p, a Zinc-Binding Integral Membrane Protein of the Peroxisome (1995)

We have cloned and sequenced PAS7, a gene required for peroxisome assembly in the yeast Pichia pastoris. The product of this gene, Pas7p, is a member of the C3HC4 superfamily of zinc-binding proteins. Point mutations that alter conserved residues of the C3HC4 motif abolish PAS7 activity and reduce zinc binding, suggesting that Pas7p binds zinc in vivo and that zinc binding is essential for PAS7 function. As with most pas mutants, pas7 cells exhibit a pronounced deficiency in import of peroxisomal matrix proteins that contain either the type 1 peroxisomal targeting signal (PTS1) or the type 2 PTS (PTS2). However, while other yeast and mammalian pas mutants accumulate ovoid, vesicular peroxisomal intermediates, loss of Pas7p leads to accumulation of membrane sheets and vesicles which lack a recognizable lumen. Thus, Pas7p appears to be essential for protein translocation into peroxisomes as well as formation of the lumen of the organelle. Consistent with these data, we find that Pas7p is an integral peroxisomal membrane protein which is entirely resistant to exogenous protease and thus appears to reside completely within the peroxisome. Our observations suggest that the function of Pas7p defines a previously unrecognized step in peroxisome assembly: formation of the peroxisome lumen. Furthermore, because the peroxisomal intermediates in the pas7 delta mutant proliferate in response to peroxisome-inducing environmental conditions, we conclude that Pas7p is not required for peroxisome proliferation.
Pharmacological Properties of Excitatory Neuromuscular Synapses in the Locust (1968)

ABSTRACT The effects of a wide range of amino acids and related compounds on retractor unguis nerve-muscle preparations from the locust, grasshopper and cockroach have been investigated. L-glutamate is the most active excitatory substance. The presence of two acidic groups and one amino group is essential for excitatory activity while the position of the amino group is of some importance in determining the level of activity. When L-glutamate is applied iontophoretically to the muscle fibres, ‘glutamate’ depolarizations are recorded only at the synaptic sites. Other evidence that the action of glutamate is restricted to the synaptic sites is presented. Perfusion of isolated locust retractor unguis nerve-muscle preparations with locust haemolymph does not markedly affect the neurally evoked mechanical responses. It appears that locust haemolymph contains little ‘free’ L-glutamate. Four acidic amino aids have been identified in the perfusate from isolated retractor unguis preparations namely, glycine, alanine, aspartate and L-glutamate. However, only L-glutamate increases in concentration during stimulation of the retractor unguis nerve.
IMPROVING DISPARITY ESTIMATION BASED ON RESIDUAL COST VOLUME AND RECONSTRUCTION ERROR VOLUME (2020)

Abstract. Recently, great progress has been made in formulating dense disparity estimation as a pixel-wise learning task to be solved by deep convolutional neural networks. However, most resulting pixel-wise disparity maps only show little detail for small structures. In this paper, we propose a two-stage architecture: we first learn initial disparities using an initial network, and then employ a disparity refinement network, guided by the initial results, which directly learns disparity corrections. Based on the initial disparities, we construct a residual cost volume between shared left and right feature maps in a potential disparity residual interval, which can capture more detailed context information. Then, the right feature map is warped with the initial disparity and a reconstruction error volume is constructed between the warped right feature map and the original left feature map, which provides a measure of correctness of the initial disparities. The main contribution of this paper is to combine the residual cost volume and the reconstruction error volume to guide training of the refinement network. We use a shallow encoder-decoder module in the refinement network and do learning from coarse to fine, which simplifies the learning problem. We evaluate our method on several challenging stereo datasets. Experimental results demonstrate that our refinement network can significantly improve the overall accuracy by reducing the estimation error by 30% compared with our initial network. Moreover, our network also achieves competitive performance compared with other CNN-based methods.
Simultaneous All-Optical Channel Aggregation and De-Aggregation for 8QAM Signal in Elastic Optical Networking (2018)

A simultaneous all-optical channel aggregation and de-aggregation scheme is proposed for two 8QAM modulation formats by employing four-wave mixing (FWM) in highly nonlinear fiber. The scheme consisting of two FWM processes is simple without photoelectric conversion, which is promising to improve efficient use of the fiber resources in elastic optical networking. The feasibility of the scheme has been confirmed by the input-output constellations and waveforms. System performance is also studied as a function of the optical signal-to-noise ratio of the two 8QAM signals. Finally, some potential application scenarios have also been discussed based on the same setup.
Piezoelectric Ultrasonic Motors (1995)

Piezoelectric ultrasonic motors are a new type of actuator. They are characterized by high torque at low rotational speed, simple mechanical design and good controllability. They also provide a high holding torque even if no power is applied. Compared to electromagnetic actuators the torque per volume ratio of piezoelectric ultrasonic motors can be higher by an order of magnitude. Recently various types of piezoelectric ultrasonic motors have been developed for industrial applications such as cameralens drive or as actuator in the head restraint of automobile seats. This paper describes several types of piezoelectric ultrasonic motors. In the first part the working principle of the travelling wave motor is explained. In the second part other types of piezoelectric ultrasonic motors are described and classified with respect to the vibration modes and contact mechanisms used in their design. Finally some open problems in piezoelectric ultrasonic motor research are addressed.
Planar bus bar optimum design in high-power converters based on FEM analysis (2010)

This paper studies on the design of planar bus bar in the high-power converter. Firstly, the impedance characteristic of planar bus bar and the performance of EMI are analyzed. The design of planar bus bar is restricted by the spatial layout for physical devices. The traditional design method, the partial element equivalent circuit (PEEC), is based on the assumption that the current was uniformly distribution, and the structure was symmetry. So it is hard to get a good result. Here, the finite elements method (FEM) which is based on the Maxwell equations, is adopted for planar bus bar design. According to the planar bus bar design, the boundary term is confirmed, so we can solve the undulation equations. Several designs for an H bridge are shown in this paper, which is constituted by IGBT modules. The ANSYS results show us the distribution of the current and the magnetic field, and works out the planar bus bar inductance value. Through the comparison and optimization of the designs, we can get a final result. The experiment shows that it is a superior method.

Preparation of poly(styrene‐<i>b</i>‐<i>N</i>‐isopropylacrylamide) micelles surface‐linked with gold nanoparticles and thermo‐responsive ultraviolet–visible absorbance (2007)

Abstract Poly(styrene‐ b ‐ N ‐isopropylacrylamide) (PSt‐ b ‐PNIPAM) with dithiobenzoate terminal group was synthesized by reversible addition‐fragmentation‐transfer polymerization. The dithiobenzoate terminal group was converted into thiol terminal group with NaBH 4 , resulting thiol‐terminated PSt‐ b ‐PNIPAM‐SH. After PSt‐ b ‐PNIPAM‐SH assembled into core‐shell micelles in aqueous solution, gold nanoparticles were in situ surface‐linked onto the micelles through the reduction of gold precursor anions with NaBH 4 . Thus, temperature responsive core/shell micelles of PSt‐ b ‐PNIPAM surface‐linked with gold nanoparticles (PSt‐ b ‐PNIPAM‐Au micelles) were obtained. Transmission Electron Microscopy revealed the successful linkage of gold nanoparticles and the dependence of the number of gold nanoparticles per micelle on the molar ratio of HAuCl 4 to thiol group of PSt‐ b ‐PNIPAM. Dynamic Light Scattering analysis demonstrated thermo‐responsive behavior of PSt‐ b ‐PNIPAM‐Au micelles. Changing the temperature of PSt‐ b ‐PNIPAM‐Au micelles led to the shrinkage of PNIPAM shell and allowed to tune the distance between gold nanoparticles. Ultraviolet–visible (UV–vis) spectroscopy clearly showed the reversible modulation of UV–vis absorbance of PSt‐ b ‐PNIPAM‐Au micelles upon heating and cooling. © 2007 Wiley Periodicals, Inc.

Efficient subsequence matching in time series databases under time and amplitude transformations (2004)

Subsequence matching in large time series databases has attracted a lot of interest and many methods have been proposed that cope with this problem in an adequate extend. However, locating subsequence matches of arbitrary length, under time and amplitude transformations, has received far less attention and is still an open problem. We present an efficient algorithm for variable-length subsequence matching under transformations that guarantees no false dismissals. Further, this algorithm uses a novel similarity criterion for determining similarity under amplitude transformations in a most efficient way. Finally, our algorithm has been tested in various experiments on real data, resulting in a running time improvement of one order of magnitude compared to the naive approach.
2T: Two-Term Indexing of Documents Using Syntactic and Semantic Constraints (2006)

Purpose of an index is to provide an intuitive navigational structure for the user into the subject matter. This paper specifies a novel, untrained method (2T) for automatically producing a two-level, semi-formal, concept-based index out of textual documents, which consists of topics rather than keywords. Using syntactic and semantic constraints and a domain ontology containing the relevant terms, we obtain high accuracy (high 80's to low 90's). Using concept categories (or semantic roles) to validate sensicality of an index term is a novel approach in semantic indexing. Resulting low-cost navigational structure can add value to businesses relying on accurate automatic document indexing (e.g. mobile news providers) or dealing with a critical learn-to-do requirement for their employees or clients (e.g. airplane maintenance). It can be implemented as a post-processing stage of full-text indexes or as readable and editable index to documentation - either printed or online.
Kinetic Evidence That the Solvent Barrier for Electron Transfer Is Absent in the Electric Double Layer (2020)

Classical capacitance studies have revealed that the first layer of water present at an aqueous metal-electrolyte interface has a dielectric constant less than 1/10th of that of bulk water. Modern theory indicates that the barrier for electron transfer will decrease substantially in this layer; yet, this important prediction has not been tested experimentally. Here, we report the interfacial electron transfer kinetics for molecules positioned at variable distances within the electric double layer of a transparent conductive oxide as a function of the Gibbs free energy change. The data indicate that the solvent reorganization is indeed near zero and increases to bulk values only when the molecules are positioned greater than 15 Å from the conductive electrode. Consistent with this conclusion, lateral intermolecular electron transfer, parallel to a semiconducting oxide electrode, was shown to be more rapid when the molecules were within the electric double layer. The results provide much needed feedback for theoretical studies and also indicate a huge kinetic advantage for aqueous electron transfer and redox catalysis that takes place proximate to a solid interface.
Some characteristics of population inversion of the<sup>4</sup><i><b>I</b></i><sub>13/2</sub>level of erbium ions in ytterbium–erbium glasses (1981)

A comparative investigation is made of phosphate, germanate, and lithium silicate glasses activated with Yb3+ and Er3+ ions in order to determine their potential usefulness for the development of laser-pumped (λ = 1.06 μ) amplifiers for short (10−8 sec) pulses at the λ = 1.54 μ wavelength. Some features of the spectral and luminescence charactenstics and the kinetics of energy transfer in these glasses are studied. It is shown that the increase in the population inversion of the 4I13/2 level of Er3+ ions in lithium silicate and germanate glasses is considerably slower than the increase in the absorbed pump energy. Possible mechanisms for this anomalous behavior are discussed. It is shown theoretically and experimentally that the main reason for this is reverse transfer of excitation energy from Er3+ to Yb3+ ions, which is almost absent in phosphate glasses.

ElaaS: An Innovative Elasticity as a Service Framework for Dynamic Management across the Cloud Stack Layers (2012)

Nowadays the general interest on Cloud Computing as a technical and business solution is growing. The pool of available cloud applications, services and platforms is increasing leveraging new features for the cloud assets provisioned to the end user. This massive amount and divergence of cloud features across the cloud stack layers introduces considerable management overhead to the various stakeholders for the effective management of both the offered products and the system itself. In this paper we focus on the challenges arise for providing dynamic elasticity management as one the fundamental features of Clouds. To this direction, we introduce the concept of Elasticity as a Service and present a generic, service-oriented framework capable to fulfill, in a personalized manner, the elasticity management needs of any cloud environment and cloud-enabled application.
Bumpless Interconnect Through Ultrafine Cu Electrodes by Means of Surface-Activated Bonding (SAB) Method (2006)

In this paper, we demonstrate the feasibility of ultrahigh-density bumpless interconnect by realizing the ultrafine pitch bonding of Cu electrodes at room temperature. The bumpless interconnect is a novel concept of bonding technology that enables a narrow bonding pitch of less than 10 /spl mu/m by overcoming the thermal strain problem. In the bumpless structure, two thin layers including an insulator and metallic interconnections on the same surface are bonded at room temperature by the surface-activated bonding (SAB) method. In order to realize the bumpless interconnect, we invented a SAB flip-chip bonder that enabled the alignment accuracy of /spl plusmn/1 /spl mu/m in the high vacuum condition. Moreover, the fabrication process of ultrafine Cu electrodes was developed by using the damascene process and reactive ion beam etching (RIE) process, and the bumpless electrodes of 3 /spl mu/m in diameter, 10 /spl mu/m in pitch, and 60 nm in height were formed. As a result, we succeeded in the interconnection of 100 000 bumpless electrodes with the interfacial resistance of less than 1 m/spl Omega/. An increase of the resistance was considerably small after thermal aging at 150/spl deg/C for 1000 h.

Sequence‐dependent binding of bis‐amidine carbazole dications to DNA (2001)

The conventional wisdom argues that DNA intercalators possess a condensed polyaromatic ring whereas DNA minor groove binders generally contain unfused aromatic heterocycles, frequently separated by amide bonds. Recently, this view has been challenged with the discovery of powerful intercalating agents formed by unfused aromatic molecules and groove binders containing a polyaromatic nucleus. Bis-amidinocarbazoles belong to this later category of drugs having a planar chromophore and capable of reading the genetic information accessible within the minor groove of AT-rich sequences [Tanious, F.A., Ding, D., Patrick, D.A., Bailly, C., Tidwell, R.R. & Wilson, W.D. (2000) Biochemistry 39, 12091-12101]. But in addition to the tight binding to AT sites, we show here that bis-amidinocarbazoles can also interact with GC sites. The extent and mode of binding of 2,7 and 3,6 substituted amidinocarbazoles to AT and GC sequences were investigated by complementary biochemical and biophysical methods. Absorption, fluorescence, melting temperature and surface plasmon resonance (SPR) measurements indicate that the position of the two amidine groups on the carbazole ring influences significantly the drug-DNA interaction. SPR and DNase I footprinting data confirm the AT-preference of the compounds and provide useful information on their additional interaction with GC sequences. The 3,6-carbazole binds approximately twice as strongly to the GC-containing hairpin oligomer than the 2,7-regioisomer. The high tendency of the 3,6 compound to intercalate into different types of DNA containing G.C base pairs is shown by electric linear dichroism. This work completes our understanding of the sequence-dependent DNA binding properties of carbazole dications.
TOXICOLOGICAL AND PHARMACOLOGICAL EFFECTS OF GADOLINIUM AND SAMARIUM CHLORIDES (1961)

A study has been made of the toxicology and pharmacology of gadolinium and samarium chlorides. The symptoms of acute toxicity following intraperitoneal injection are described. The chronic oral ingestion of both chemicals for 12 weeks produced no effects on growth or the blood picture, and only the male rats receiving gadolinium chloride showed liver damage. The pharmacological responses to both chemicals were mainly depressant on all systems studied, and death was associated with cardiovascular collapse coupled with respiratory paralysis. The greatest damage seen was on abraded skin, where non-healing ulcers were produced by both chemicals, whereas irritation of intact skin and ocular tissues was only transient in nature.
