Enhancement of Collapse Resistance of UOE Pipe Based on Systematic Exploitation of Thermal Cycle of Coating Process (2008)

The present paper discusses recent results of an ongoing study on the effect of thermal treatment on collapse strength of cold formed pipes, for instance those following the UOE production route. It has been recognized that thermal treatment as encountered during thermal cycle of pipe coating processes may compensate the reduction of compressive yield strength owing to cold plastic deformation induced during forming. This effect has been systematically analyzed. Enhancement of collapse resistance exploiting the thermal cycle of coating process was studied based on experimental evidence, Finite Element simulations as well as theoretical analysis. It is herein shown that appropriate thermal treatment manifests itself positively with respect to compressive yield strength, leading to significantly improved collapse pressures. As a result fabrication factors of one and even higher may be applicable.
Expression of VEGF and bcl-2 in Olfactory Neuroblastoma: Association with Microvessel Density (2009)

Introduction: Olfactory neuroblastoma (ONB) is a rare malignant tumor that is believed to arise from the olfactory epithelium in the vault of the nasal cavity. Neoangiogenesis plays a fundamental role in the pathogenesis and progression of malignant solid tumors and this process is controlled by angiogenic growth factors. A number of angiogenic factors, including vascular endothelial growth factor (VEGF), have been shown to be expressed in neuroblastic tumors. In hypoxic conditions, VEGF expression is regulated via hypoxia-inducible factor (HIF)-1a and bcl-2. Activation of the VEGF receptors (VEGF-R1/R2) by VEGF promotes neoangiogenesis in various malignant tumors.
Update on sexed semen technology in cattle (2014)

The technology in current use for sexing sperm represents remarkable feats of engineering. These flow cytometer/cell sorters can make over 30 000 consecutive evaluations of individual sperm each second for each nozzle and sort the sperm into three containers: X-sperm, Y-sperm and unsexable plus dead sperm. Even at these speeds it is not economical to package sperm at standard numbers per inseminate. However, with excellent management, pregnancy rates in cattle with 2 million sexed sperm per insemination dose are about 80% of those with conventional semen at normal sperm doses. This lowered fertility, in part due to damage to sperm during sorting, plus the extra cost of sexed semen limits the applications that are economically feasible. Even so, on the order of 2 million doses of bovine semen are sexed annually in the United States. The main application is for dairy heifers to have heifer calves, either for herd expansion or for sale as replacements, often for eventual export. Breeders of purebred cattle often use sexed semen for specific matings; thawing and then sexing frozen semen and immediately using the few resulting sexed sperm for in vitro fertilization is done with increasing frequency. Beef cattle producers are starting to use sexed semen to produce crossbred female replacements. Proprietary improvements in sperm sexing procedures, implemented in 2013, are claimed to improve fertility between 4 and 6 percentage points, or about 10%.
Operation modes and self-motion of 2-RUU parallel manipulator (2016)

This paper deals with the characterisation of the operation modes of the 2-RUU parallel manipulator with an algebraic approach, namely the study's kinematic mapping of the Euclidean group SE(3). The manipulator is described by a set of eight constraint equations and the primary decomposition reveals that the mechanism has three 4-dof operation modes. The singularity conditions are obtained by deriving the determinant of the Jacobian matrix of the constraint equations with respect to the study parameters. It is shown that there exist singular configurations in which the 2-RUU parallel manipulator may switch from one operation mode to another operation mode, which is known as constraint singularity. All the singular configurations are mapped onto the joint space and are physically interpreted. Eventually, the 2-RUU parallel manipulator may switch from the 1st Schönflies mode to the 2nd Schönflies mode, or vice versa, through the additional 4-dof mode that contains self-motion.

The Build-Up of Bimetallic Transition Metal Clusters (1998)

The synthesis and reaction chemistry of high nuclearity transilion metal carbonyl clusters is briefly reviewed, and new synthetic strategies leading to the “rational” synthesis of bimetallic clusters containing metal cores of over 1 nm in dimension are described. The solid state structures of a number of osmium/mercury, osmium/gold and ruthenium/copper bimetallic clusters are discussed with regard to the nature of their formation, and of their bonding and redox properties. Suggestions are made as to how the synthetic strategies can be adapted to prepare bimetallic clusters of industrially useful combinations of metals. Recent work showing that bimetallic nanoparticles prepared from clusters are catalytically active when anchored inside mesoporous silica is also discussed.

Nitrosporeusines A and B, Unprecedented Thioester-Bearing Alkaloids from the Arctic Streptomyces nitrosporeus (2013)

Chemical examination of an arctic actinomycete Streptomyces nitrosporeus resulted in the isolation of two new alkaloids named nitrosporeusines A (1) and B (2), an unprecedented skeleton containing benzenecarbothioc cyclopenta[c]pyrrole-1,3-dione. Their structures were determined through extensive spectroscopic analyses in association with X-ray single crystal diffraction. Both 1 and 2 exhibited inhibitory activities against the H1N1 virus in MDCK cells.

Life with GenJam: interacting with a musical IGA (2003)

GenJam, short for genetic jammer, is an interactive genetic algorithm (IGA) that models a jazz improviser and performs as a featured soloist in the author's virtual quintet. GenJam evolves populations of melodic ideas under the guidance of a human mentor, whose feedback provides the environment under which individual ideas either survive to breed or die off. GenJam also uses its genetic algorithm machinery as a real-time melodic development paradigm to evolve phrases played by a human into its improvised responses in chase choruses. The paper provides an overview of the GenJam architecture and focuses on interface issues for three classes of users: mentors who train GenJam individually, audiences who train GenJam collectively, and performers who interact with GenJam in real-time performance situations.
Variable rate data transmission with blind ratedetection for coherent DS-CDMA mobile radio (1996)

A variable rate data transmission scheme with blind rate detection is described for pilot-symbol-assisted coherent DS-CDMA mobile radio. Cyclic redundancy check (CRC) coding and decoding is used for blind rate detection. Computer simulations of eight-rate variable rate data transmission demonstrate that when 16 bit CRC is used, the loss in required total Eb/N0 at a frame error rate of 10-2 under two-path Rayleigh fading, is only ~0.1 dB from the known rate case.
Learners' Use of Their First Language in ESL Classroom Interactions (2007)

There are few studies which document learners' use of L1 in the ESL classroom, perhaps because the emphasis has traditionally been on learning English through English, and partly because of the relative scarcity of bilingual teachers, and lack of support for their potential to use L1 as a purposeful teaching strategy (Ellis, this volume; O'Grady, 1987). This paper reports empirical findings of a classroom-based research investigation into learners' actual L1 use in a multilingual classroom in the Adult Migrant English Service, NSW Transcriptions of speech data are used to explore the uses of L1 as a language learning resource. Learners were found to use L1 as a strategy for communication and for learning, and also to perform metalinguistic functions which are conducive to learning. Some implications for teaching practices are discussed.
Electrochemical Impedance Spectroscopy of Coated Aluminum Beverage Containers: Part 1 — Determination of an Optimal Parameter for Large Sample Evaluation (1994)

Future environmental regulations will limit the volatile organic content of many coatings, including those used on the internal walls of aluminum (Al) cans. Thus, the coating industry is interested in rapid development and testing of new coatings. Commercial coating evaluation requires testing of a large number of samples and statistical analysis of data to determine the performance of the population. The present study focused on determining a performance parameter that could be obtained quickly from impedance spectra. An equivalent circuit model (ECM) was developed by examining uncoated Al and coated Al containing intentional defects in chloride (Cl–) solution. Three parameters of the model — coating capacitance (Cc), pore resistance (Rpore), and low-frequency impedance (determined from data at ~ 0.05 Hz) — were examined for three thicknesses of the same coating. They were evaluated in terms of correlation to visual performance and facility of acquisition. Results indicate the low-frequency impedance was the optimal parameter because it correlated with visual performance and could be obtained readily from the data. A future study will use this parameter to determine the coating performance of a population using statistical methods.
Multi-Classifier Tree With Transient Features for Drift Compensation in Electronic Nose (2020)

Long term sensors drift is a challenging problem to solve for instruments like an Electronic Nose System (ENS). These electronic instruments rely on Machine Learning (ML) algorithms for recognizing the sensed odors. The effect of long-term drift influences the performance of ML algorithms and the models those are trained on drift free data fail to perform on the drifted data. Moreover, the response of an electronic nose system depends on the variable response of the sensors and a delay is expected in reaching a steady state by the sensors. In this paper, these two problems of `sensors long term drift' and `delayed response' are solved simultaneously to propose a robust and fast electronic nose system, with following merits: (i) only initial transient state features are used in the proposed system without waiting for the sensors to reach a steady state, (ii) a modified boxplot approach is used to handle noisy/drifted data points as a preprocessing step before the classification setup, (iii) a heuristic tree classification approach with optimized transient features is proposed, (iv) the proposed approach only relies on adapted ML methods contrary to the traditional approaches like system recalibration or sensors replacement for handling sensors drift, and (v) the proposed ML model does not require any target domain data and uses only the source domain data for learning the classifier, opposed to the other ML solutions available in the existing literature. The proposed method is tested using a large scale gas sensors drift benchmark dataset available freely on UCI Machine Learning repository and is found better than the existing state-of-the art approaches with an overall accuracy of 87.34%.
Effects of Contact Surface Pressure and Surface Roughness on Friction Properties of Various LB Films with the Same Tip Group (2022)

Organic Friction Modifier additives are widely used to reduce friction and wear on sliding surface. In this study, we investigated the effect of different sliding conditions, such as surface roughness, surface pressure, and medium, on the friction reduction effect of adsorption films with different surface coverage, and examined the factors that affect the frictional properties of adsorption films. To investigate the effect of the different packing densities on the frictional properties of the adsorption films, we firstly prepared adsorption films with the same tip group but different packing densities by the LB method, and confirmed the validity of the preparation of the LB films by neutron reflectometry. The friction properties of the adsorption films were measured under the different surface roughness and pressure using atomic force microscopy. The results suggest that there is an optimum packing density for surface pressure and surface roughness.
Methylated tetra‐amide derivatives of paramagnetic complexes for magnetic resonance biosensing with both BIRDS and CEST (2021)

Paramagnetic agents that utilize two mechanisms to provide physiological information by magnetic resonance imaging (MRI) and magnetic resonance spectroscopic imaging (MRSI) are described. MRI with chemical exchange saturation transfer (CEST) takes advantage of the agent's exchangeable protons (e.g., -OH or -NH<sub>x</sub> , where 2 ≥ x ≥ 1) to create pH contrast. The agent's incorporation of non-exchangeable protons (e.g., -CH<sub>y</sub> , where 3 ≥ y ≥ 1) makes it possible to map tissue temperature and/or pH using an MRSI method called biosensor imaging of redundant deviation in shifts (BIRDS). Hybrid probes based upon 1,4,7,10-tetraazacyclododecane-1,4,7,10-tetraacetate chelate (DOTA<sup>4-</sup> ) and its methylated analog (1,4,7,10-tetraazacyclododecane-α, α', α″, α‴-tetramethyl-1,4,7,10-tetraacetate, DOTMA<sup>4-</sup> ) were synthesized, and modified to create new tetra-amide chelates. Addition of several methyl groups per pendent arm of the symmetrical chelates, positioned proximally and distally to thulium ions (Tm<sup>3+</sup> ), gave rise to favorable BIRDS properties (i.e., high signal-to-noise ratio (SNR) from non-exchangeable methyl proton peaks) and CEST responsiveness (i.e., from amide exchangeable protons). Structures of the Tm<sup>3+</sup> probes elucidate the influence of methyl group placement on sensor performance. An eight-coordinate geometry with high symmetry was observed for the complexes: Tm-L1 was based on DOTA<sup>4-</sup> , whereas Tm-L2 and Tm-L3 were based on DOTMA<sup>4-</sup> , where the latter contained an additional carboxylate at the distal end of each arm. The distance of Tm<sup>3+</sup> from terminal methyl carbons is a key determinant for sustaining BIRDS temperature sensitivity without compromising CEST pH contrast; however, water solubility was influenced by introduction of hydrophobic methyl groups and hydrophilic carboxylate. Combined BIRDS and CEST detection of Tm-L2, which features two high-SNR methyl peaks and a strong amide CEST peak, should enable simultaneous temperature and pH measurements for high-resolution molecular imaging in vivo.

THE CONDUCTIVITY OF A LONGITUDINAL-SHOCK-WAVE-COMPRESSED Nd2Fe14B HARD FERROMAGNETICS (2002)

The conductivity of Nd 2 Fe 14 B hard ferromagnetic subjected to compression by a longitudinal shock wave (the shock wave propagates along the magnetization vector M) with a pressure of 35 GPa is measured. The results of the experiments show that the conductivity of the longitudinal-shock-wave-compressed Nd 2 Fe 14 B is σ sw = (2.83 ± 0.24) × 10 2 (Ω cm ) -1 , which is 22 times lower than the conductivity of Nd 2 Fe 14 B under normal conditions.
Dynamic stereochemistry of imines and derivatives. Part 13. The stereochemistry of the products from peroxyacid oxidation of bis-N-alkylaldimines (1978)

Bis-N-alkylimines derived from glyoxal (1) and (2) and terephthalaldehyde (3) and (4) have been oxidised with m-chloroperoxybenzoic acid to give stereoisomeric mixtures of bis-oxaziridines. The bis-oxaziridines obtained from (1) have been separated and unequivocally assigned trans,trans[racemic](5a) and trans,trans[meso](5b) configurations by a combination of n.m.r. methods and asymmetric synthesis. Bis-oxaziridine products resulting from oxidation of the bis-imines (3) and (4) are also configurationally stable at nitrogen, and are formed as diastereoisomeric mixtures. Analysis of the bis-oxaziridine product mixture by 1H and 13C n.m.r. indicates that the major components have the trans,trans and cis,trans stereochemistry though traces of the cis,cis isomer are probably present. Each of these components may be a mixture of meso and racemic isomers which are unresolved in the n.m.r. spectra. 1H and 13C shifts and some 13C–H coupling constants are reported for the bis-oxaziridnes.
Adaptive filtering for single target tracking (2009)

Many algorithms may be applied to solve the target tracking problem, including the Kalman Filter and different types of nonlinear filters, such as the Extended Kalman Filter (EKF), Unscented Kalman Filter (UKF) and Particle Filter (PF). This paper describes an intelligent algorithm that was developed to elegantly select the appropriate filtering technique depending on the problem and the scenario, based upon a sliding window of the Normalized Innovation Squared (NIS). This technique shows promise for the single target, single radar tracking problem domain. Future work is planned to expand the use of this technique to multiple targets and multiple sensors.

High Dose Dosimetry Using Optically Stimulated Luminescence (1996)

Very precise high level dosimetry is currently being accomplished using electron spin resonance (ESR) of the radiation damage centres in alanine. While the technique works well, the complications and cost of using ESR machines could be simplified by using optically stimulated luminescence (OSL) techniques. Battelle, in collaboration with Landauer, Inc., has been developing low cost OSL polymer detectors manufactured by either injection moulding or extrusion. LiF and Al&lt;inf&gt;2&lt;/inf&gt;O&lt;inf&gt;3&lt;/inf&gt; are the OSL active materials that are uniformly mixed with a polymer prior to dosemeter fabrication. Grain sizes of the LiF are usually kept below 10 �m in order to disperse the material uniformly. Plastic manufacturing techniques readily produce uniform detectors. The aim of the project is to produce an inexpensive detector that covers the range of 10 R-106 R. Readout is accomplished using a laser or light source to excite the OSL radiation damage centres. Luminescence of the OSL radiation damage centres is measured by optical filtration of the laser or light source. The method of fabrication, readout techniques, and dosimetric response of the new detectors are presented.
Application of the 2,2‘-Azinobis(3-ethylbenzothiazoline-6-sulfonic acid) Radical Cation Assay to a Flow Injection System for the Evaluation of Antioxidant Activity of Some Pure Compounds and Beverages (2002)

The 2,2'-azinobis(3-ethylbenzothiazoline-6-sulfonic acid) radical cation (ABTS(*)(+)) assay was adapted to a flow injection (FI) system to obtain a sensitive and rapid technique for the monitoring of antioxidant activity of pure compounds and complex matrixes, such as beverages and food extracts. The FI system includes a HPLC pump that flows the mobile phase (a solution of ABTS(*)(+) in ethanol) through a 20 microL loop injector, a single bead string reactor filled with acid-washed silanized beads, a delay coil and a photodiode array UV-visible detector. The technique was very sensitive, with limits of detection and of quantification of 4.14 and 9.29 micromol of Trolox/L, respectively, and demonstrated high repeatability and reproducibility. The proposed technique was then applied to the evaluation of the antioxidant activity of some pure compounds, demonstrating good agreement with published data obtained by the original spectrophotometric ABTS(*)(+) assay. Finally, the total antioxidant activity of 10 beverages was determined by both the proposed and the original method. The values ranged from 0.09 mmol L(-)(1) for cola to 49.24 mmol L(-)(1) for espresso coffee and did not result significantly different from those obtained by the original spectrophotometric ABTS(*)(+) assay (Student's paired t-test: t = 1.4074, p = 0.1929). In conclusion, the proposed FI technique seems suitable for the direct, rapid and reliable monitoring of total antioxidant activity of pure compounds and beverages and, due to the ability to operate in continuous, it allows the analysis of about 30 samples h(-)(1) making the assay particularly suitable for large screening of total antioxidant activity in food samples.
Structural and mechanical properties of nanostructured metalloceramic coatings on cobalt chrome alloys (2003)

A functionally graded nanocrystalline metalloceramic coating on cobalt–chrome alloys was investigated with thin-film x-ray diffraction (XRD), nanoindentation, and scratch adhesion testing. The gradual transition in bonding from metallic to predominantly covalent along with a nanocrystalline grain structure provides a unique material system with excellent strength, toughness, and adhesion properties. XRD analysis of the (CrTiN) coating suggests a cubic sodium chloride phase structure with a=4.2169±0.0035 Å. Nanoindentation measurements of the coating result in a hardness of 27 GPa and Young’s modulus of 320 GPa. The graded metallic/covalent nature of the coating with high plasticity also results in excellent film/substrate adhesion as shown by an average critical force of 44±5 N in scratch testing.
