Mechanistic Investigations on the Formation of Supramolecular Cylindrical Shaped Oligomers and Polymers by Living Ring Opening Metathesis Polymerization of a 7-Oxanorbornene Monomer Substituted with Two Tapered Monodendrons (1997)

The synthesis of the monomer exo,exo-5,6-bis[[[(3,4,5-tris((4-(dodecyl-1-oxy)benzyl)oxy)]benzyl)oxy]carbonyl]-7-oxabicyclo[2.2.1]hept-2-ene (4), containing two tapered monodendrons and its living ring-opening metathesis polymerization initiated with RuCl2(CHPh)(PCy3)2 are discussed. Oligomers and polymers with narrow molecular weight distribution (Mw/Mn = 1.06−1.29) and degrees of polymerization (DP) from 6 to 120, which correspond to Mn from 12 600 to 252 800, were synthesized and characterized. The monomer (4) and the corresponding polymers (5) self-assemble into disklike and cylindrical shapes which produce an enantiotropic hexagonal columnar (Φh) liquid crystalline (LC) phase. The analysis of the Φh phase of the monomer, oligomers, and polymers as a function of the DP reveals four regions and mechanisms for the generation of the Φh phase, i.e., below the DP which forms a disklike molecule, below the DP which corresponds to the maximum length of a disklike molecule (DP = 26), up to the DP which corresponds to the persistence length of the rodlike cylinder (DP = 64), and above this value.
Gypsum Compatibility of Antimicrobial Alginates After Spray Disinfection (1994)

The addition of 1% chlorhexidine diacetate to COE Hydrophilic Gel Alginate has decreased its compatibility with the dental stones and disinfectants tested when compared with its nonantimicrobial counterpart. In terms of gypsum compatibility, the nonantimicrobial COE Alginate was compatible with all disinfectant and gypsum combinations tested. The addition of 1.70% didecyldimethyl ammonium chloride to Jeltrate Plus Antimicrobial Alginate has increased its compatibility with all the dental stones tested. A strong positive correlation (r = 0.7398) was found between visual gypsum compatibility evaluation scores and surface roughness of gypsum casts.
Assistive Technologies and Children-Robot Interaction. (2007)

Mobile robots are machines that can move and act in the real world, making it possible to generate a multitude of interplay situations, which can engage children and encourage interaction in a variety of different ways. Mobility, appearance, interaction modalities (e.g., sound, light, moving parts) and behaviour (predetermined and adaptive) can all have an influence in sustaining the interest (and therefore learning) of typically developing children or children with specific deficits such as autism. This paper summarizes findings from two of our on-going projects, one using a spherical mobile robot and the other using a humanoid-like robot toy.
Statistical analysis of Gabor-filter representation (2002)

A successful face recognition system calculates similarity of face images based on the activation of multiscale and multiorientation Gabor kernels, but without utilizing any statistical properties of that representation. A method has been developed to weight the contribution of each element (1920 kernels) in the representation according to their power of predicting similarity of faces. The same statistical method has also been used to assess how changes in orientation (horizontal and vertical), expression, illumination and background contribute to the overall variance in the kernel activations. Weighting the elements in the representation according to their discriminative power has shown to increase recognition performance on a Caucasian and on a Japanese test image-set. It has also been demonstrated that such weighting method is particularly useful when data compression is a key requirement.
Quantum Dot Based Infrared Focal Plane Arrays (2007)

In the past decade, there has been active research on infrared detectors based on intersubband transitions in self-assembled quantum dots (QDs). In the past two years, at least four research groups have independently demonstrated focal plane arrays based on this technology. In this paper, the progress from the first raster scanned image obtained with a QD detector to the demonstration of a 640 512 imager based on self-assembled QDs is reviewed. In particular, emphasis will be placed on a novel quantum dots-in-a-well (DWELL) design, which represents a hybrid between a conventional quantum-well infrared photodetector (QWIP) and a quantum-dot infrared photodetector (QDIP). In the DWELL detectors, the active region consists of InAs quantum dots embedded in an InGaAs quantum well. Like QDIPs, the DWELL detectors have 3-D confinement and display normal incidence operation while demonstrating reproducible ldquodial-in recipesrdquo for control over the operating wavelength, like QWIPs. Moreover, the DWELL detectors also have demonstrated bias-tunability and multicolor operation in the midwave infrared (MWIR, 3-5 ), long-wave infrared (LWIR, 8-12 ), and very long wave infrared (VLWIR, ) regimes. Recently midformat 320 256 and 640 512 focal plane arrays (FPAs) with an NETD of 40 mK at have been reported. The paper will conclude with a perspective on the future directions on the research on QDIP FPA including enhanced functionality and higher operating temperatures.
Formulation of the kinematic model of a general (6 DOF) robot manipulator using a screw operator (1987)

Abstract In general, the manipulator's end‐effector can be located in a desired position and orientation in its work‐space through angular and/or linear displacements of its joints. These joint coordinates can be obtained by solving the loop‐closure equation of the manipulator's kinematic model. The most common method for obtaining this equation is based on the point coordinates 4×4 homogeneous transformation matrix. This method uses a special set of frames which are adapted to the manipulator's configuration. Within the last few years there has been some interest in the use of screw operators (line transformations) to model the kinematic configuration of manipulators and to form the loop‐closure equation. In this article, a kinematic model of a general (6 DOF) manipulator is obtained through the application of a screw operator (dual‐unit quaternion) to represent the screw displacements of the line coordinates of the manipulator link and joint axes. The loop‐closure equation of the closed kinematic chain is obtained by introducing a hypothetical link/joint at the manipulator's end‐effector location. The resultant non‐linear loop‐closure equation is then solved for the joint coordinates using a numerical technique. The method is illustrated with an example.
Site-Directed Mutagenesis and Generation of Chimeric Viruses by Homologous Recombination in Yeast to Facilitate Analysis of Plant-Virus Interactions (2004)

A yeast homologous recombination system was used to generate mutants and chimeras in the genome of Potato leafroll virus (PLRV). A yeast-bacteria shuttle vector was developed that allows mutants and chimeras generated in yeast to be transformed into Escherichia coli for confirmation of the mutations and transformed into Agrobacterium tumefaciens to facilitate agroinfection of plants by the mutant PLRV genomes. The advantages of the system include the high frequency of recovered mutants generated by yeast homologous recombination, the ability to generate over 20 mutants and chimeras using only two restriction endonuclease sites, the ability to introduce multiple additional sequences using three and four DNA fragments, and the mobilization of the same plasmid from yeast to E. coli, A. tumefaciens, and plants. The wild-type PLRV genome showed no loss of virulence after sequential propagation in yeast, E. coli, and A. tumefaciens. Moreover, many PLRV clones with mutations generated in the capsid protein and readthrough domain of the capsid protein replicated and moved throughout plants. This approach will facilitate the analysis of plant-virus interactions of in vivo-generated mutants for many plant viruses, especially those not transmissible mechanically to plants.
Data set for cloning and characterization of heterologous transporters in Saccharomyces cerevisiae and identification of important amino acids for xylose utilization (2015)

The efficient uptake is important for the xylose utilization by Saccharomyces cerevisiae. A heterogenous transporter Mgt05196p was cloned from Meyerozyma guilliermondii and expressed in Saccharomyces cerevisiae[1]. This data article contains the transport characteristics of Mgt05196p in S. cerevisiae. The fluorescence of fusion protein Mgt05196p-GFP expressing strain was located on the cell surface demonstrated that the heterogenous transporter Mgt05196p was targeted to the plasma membrane of S. cerevisiae. The expressing of Mgt05196p in the hxt null S. cerevisiae endowed the strain with the glucose and d-xylose absorption capacity, as well as expressing the native d-xylose transporter Gal2p. The transmembrane domains of Mgt05196p were predicted and compared with the XylEp, whose crystal structure was revealed. And then, the homologous modeling of Mgt05196p was built basing on the XylEp to find out the crucial amino acid residues for sugars binding and transport.
Guest Editorial Special Issue on Systematic Approaches to Human–Machine Interface: Improving Resilience, Robustness, and Stability (2016)

The papers in this special section focus on systematic approaches to human-machine interface applications. The motivation for this special issue is the growing increase of remote mission management, unmanned aircraft systems, NextGen operations in the U.S. and its Single European Sky Air Traffic Management Research counterparts in Europe, and other similarly integrated systems of systems that include complex human–machine systems with high levels of autonomy and team dynamics that are difficult to understand and analyze. The issue explores key research areas that impact the properties of these systems, which rely on varied degrees of human and machine interactions. The special issue is a result of the continued interest in the formal verification of complex human–machine systems.
Globally Coherent Text Generation with Neural Checklist Models (2016)

and what still needs to be said -especially when constructing long texts. We present the neural checklist model, a recurrent neural network that models global coherence by storing and updating an agenda of text strings which should be mentioned somewhere in the output. The model generates output by dynamically adjusting the interpolation among a language model and a pair of attention models that encourage references to agenda items. Evaluations on cooking recipes and dialogue system responses demonstrate high coherence with greatly improved semantic coverage of the agenda.
Cardiac Surgery in Patients with Drug Eluting Stents: The Risk of Stopping Clopidogrel (2007)

Recommendations for the duration of clopidogrel (Plavix ® , Bristol Meyers Squibb, New York, NY) therapy following drug eluting stent (DES) insertion have been subject to recent criticism. Suggested recommendations for the continuation of clopidogrel have been extended to one year following DES insertion. However, patients with a previously inserted DES who now require cardiac surgery are requested to stop clopidogrel perioperatively. The safety of this practice is unclear. We report two cases of elective cardiac surgical intervention after the insertion of DES complicated by perioperative or intraoperative acute coronary ischemia attributed to DES closure.
Gel filtration, ion exchange chromatography and chemical analysis of macromolecules present in acquired anamel pellicle (2‐hour‐pellicle) (1982)

Proteins obtained from the surface of human teeth in vivo were solubilized in EDTA and subjected to gel permeation, ionic exchange chromatography and amino acid analysis. It was found that the main component was anionic and was eluted between albumin and lysozyme on Sepharose. It contained abundant amounts of serine, glycine and glutamic acid. A salivary phosphoprotein of similar amino acid composition has previously been purified.
Physical and chemical aging of aluminum(III) 8-hydroxyquinoline: Failure and materials design in organic light-emitting diodes (1999)

The chemical and physical aging of aluminum(III) 8-hydroxyquinoline (Alq3) films was studied by a variety of techniques. The products of these mechanisms produce electron trap states below the conduction band, or lowest unoccupied molecular orbital level (LUMO), of Alq3. The distribution of these trap states was shown to affect the charge transport and luminescence characteristics of organic light-emitting diodes (OLEDs) based on this material. ^ The chief route of chemical decomposition is the substitution of water with one of the ligands of Alq3. This reaction was characterized by gas chromatography, and quantitative kinetics were obtained to measure the impact of chemical aging in real device architectures. Electrochemical reduction of either Alq3 or the free ligand, 8-hydroxyquinoline (Hq), facilitates dissociation of the complex, especially when oxygen is present. The reduced form of Hq is unstable and forms quinones, hydroquinones, and charge transfer complexes, the latter of which will cause an additional loss in the performance of OLEDs due to luminescence quenching. This instability is particularly important because Hq traps electrons during device operation. ^ Physical aging and crystallization were observed by X-ray diffraction, calorimetry, and fluorescence spectroscopy. Films which were amorphous upon deposition, crystallized rapidly upon annealing at temperatures below their glass transition. Blends of Alq3 with aluminum(III) 5-methyl-8-hydroxyquinoline were proposed for thermally stable amorphous emitting layers in OLEDs. Films coevaporated at a 1:1 ratio did not show evidence of crystallization even after long annealing periods at temperatures as high as 160°C. ^ Conduction in Alq3 was considered based on trap-charge limited conduction of electrons in the bulk. The evolution of a narrow Gaussian distribution of localized trap states below the LUMO, lying against a natural exponential background, was used to explain the changes in the current-voltage characteristics and electroluminescence efficiency observed over time in OLEDs by many researchers. Chemical aging kinetics were used to predict the rate at which OLED performance was compromised. ^
P-BEMP: A New Efficient and Commercially Available User-Friendly and Recyclable Heterogeneous Organocatalyst for the Michael Addition of 1,3-Dicarbonyl Compounds (2004)

Michael addition of 1,3-dicarbonyls with various Michael acceptors has been found to be catalyzed by commercially available, user-friendly and recyclable N-phenyl-tris(di-methylamino)iminophosphorane immobilized on polystyrene resin (P-BEMP). The reaction does not require anhydrous solvents or inert atmosphere and proceeds smoothly at room temperature leading to the corresponding adducts, which can be conveniently isolated in high yield and with high chemical purity by simple filtration.
The New Trend of Moral Education in Modernization (2000)

WT5”BZ]:Moral education not only has the capacity for being suited to the culture within a society,but also has the capacity for being applied to the culture. One of the basic expectations of our society for moral education in schools is to make people learn to choose the orientation of moral value. Moral education includes emphasis on the cultivation of the moral quality of a subject, the cultivation of the moral personality of a subject,and opposition to simple moral inculcation. Education in the humanities is the cornerstone of moral education, and the aim of such education is to draw out individuality. The quality of individual morality is determined by the nature of education in the humanities. The cultivation of individuality is the final goal of moral education, the living world is the root of moral education, and the combination of individualization and the living world is the basic trend of moral education.

Treatment with mitomycin C (MMC) increases Pgp-EGFP fusion protein at the cell surface. (2015)

&lt;p&gt;(A) hCMEC/D3-MDR1-EGFP (doxycycline-on) cells were treated with MMC (1 µM) for 2 or 4 h and analyzed at the end of the 2 h-exposure period or 20 h after the 4 h-exposure period. Western blot analyses of cell surface proteins isolated via EZ-Link Sulfo-NHS-SS-Biotin-Neutravidin assay revealed an obvious increase of Pgp-EGFP abundance at the cell surface after MMC exposure, whereas no effect on intracellular Pgp was seen. One representative result of six independent experiments is shown. In (B), Pgp-EGFP bands of the cell surface were analyzed densitometrically and Pgp signals were normalized relative to the coomassie-stained portion of the gel. Data variability is shown as ± SEM of six experiments; significant differences of treated vs. untreated samples are indicated by asterisk (P&lt;0.05). (C, D) No significant induction of Pgp-EGFP fusion protein was measured in whole cell lysates at the same exposure conditions used in (A). Respective P values in D were 0.5502 (2 h MMC) and 0.2534 (24 h MMC). Pgp-EGFP bands were analyzed densitometrically and Pgp signals were normalized on actin. Data variability is shown as ± SEM of three experiments.&lt;/p&gt;

What can we do with 1000 plastid genomes? (2017)

The plastid genome of plants is the smallest and most gene-rich of the three genomes in each cell and the one generally present in the highest copy number. As a result, obtaining plastid DNA sequence is a particularly cost-effective way of discovering genetic information about a plant. Until recently, the sequence information gathered in this way was generally limited to small portions of the genome amplified by polymerase chain reaction, but recent advances in sequencing technology have stimulated a substantial rate of increase in the sequencing of complete plastid genomes. Within the last year, the number of complete plastid genomes accessible in public sequence repositories has exceeded 1000. This sudden flood of data raises numerous challenges in data analysis and interpretation, but also offers the keys to potential insights across large swathes of plant biology. We examine what has been learnt so far, what more could be learnt if we look at the data in the right way, and what we might gain from the tens of thousands more genome sequences that will surely arrive in the next few years. The most exciting new discoveries are likely to be made at the interdisciplinary interfaces between molecular biology and ecology.
Molecular Layer Epitaxy (1985)

We report, for the first time, the success of molecular layer epitaxy (MLE) using as an As containing gas and trimethyl‐gallium (TMG) as a Ga containing gas. Growth conditions for a single layer by layer deposition process were investigated as a function of the substrate temperature, the pressure in the growth chamber, the admittance quantity per cycle, and photoirradiation. The substrate temperature of 500°C fulfilled the conditions for a monolayer growth, where the film thickness per one cycle is saturated with the admittance quantity, at the higher temperature that increased with the TMG admittance quantity. The electrical properties of the film grown by MLE method strongly depended on the gas admittance rate, i.e., pressure in the growth chamber. The carrier density of the film proportionally decreased with increasing pressure and decreasing TMG pressure. However, all growth films show p‐type behavior with a carrier density of . Photoirradiation during the growth by a high pressure Hg lamp, Ar laser (514.5 nm), and with a doubler (257.3 nm) largely improved the surface morphology and electrical properties of the films by MLE.
Restaurative und rekonstruktive Behandlung einer Amelogenesis imperfecta nach 18 Jahren – ein publizierter Fall wird volljährig (2022)

The diagnosis and treatment of amelogenesis imperfecta (AI) represents a considerable rehabilitative challenge. Three critical aspects must be emphasised in particular: 1. as a congenital dental dysplasia, AI is a congenital defect, is covered by federal disability insurance and requires early definitive treatment before the age of twenty; 2. treatment is complex, interdisciplinary and usually invasive; and 3. restorations must be fixed on structurally compromised tooth structure.
The Changing U.S. Financial System: Some Implications for the Monetary Transmission Mechanism (2002)

An important part of monetary policy is the monetary transmission mechanism, the process by which monetary policy actions influence the economy. While the transmission mechanism involves a number of channels, including exchange rates, bank credit, and asset prices, most economists consider interest rates to be the principal avenue by which monetary policy affects economic activity.> In recent decades, significant changes in the structure of financial markets and institutions in the United States may have altered the interest rate channel. Key developments include the deregulation of the financial system, the growth of capital markets as an alternative to bank intermediation, increased competition among intermediaries both domestically and internationally, and greater transparency by the Federal Reserve about monetary policy operations. These changes may have altered both the timing and magnitude of the response of interest rates to monetary policy. Indeed, the failure of long-term interest rates to respond to monetary policy easing during the past year has been cited in the financial press as an indication that monetary policy may now have less influence on interest rates than in the past.> Sellon examines how the changing financial system has affected the interest rate channel of monetary policy. He finds that the response of interest rates to monetary policy, rather than diminishing, has actually increased considerably over time. Indeed, bank lending rates on consumer and business loans and mortgage rates now appear to exhibit a much stronger and faster response to monetary policy actions than in the past. Moreover, institutional changes, such as the increased use of variable-rate loans and the availability of low-cost mortgage refinancing, may have altered the transmission mechanism, potentially broadening the influence of monetary policy on the economy.
The Anatomy of Stress Incontinence: Magnetic Resonance Imaging of the Female Bladder Neck and Urethra (1990)

Clinical, urodynamic, radiological and endoscopic evaluations as well as operative results on more than 800 cases of stress incontinence treated at our medical center have led to a better understanding of the pathophysiology of female stress incontinence. We attempt to correlate these physiological concepts with information obtained from magnetic resonance images of the paraurethral and bladder neck areas in patients with known stress incontinence and normal controls. All magnetic resonance images were compared to cadaver step sections of the female pelvis. Normal controls without stress incontinence were used to define normal anatomy by magnetic resonance imaging. Etiology of incontinence was divided into either intrinsic urethral damage or anatomical malposition of an intact sphincteric unit. Our findings not only provide valuable support to basic concepts of the pathophysiology of stress incontinence but also help to establish normal findings of female paraurethral and bladder neck anatomy as seen by magnetic resonance imaging.
