Supply‐Chain Strategy: Organizational Influence Through Supplier Alliances (1997)

The role of supply‐chain management as an integral element in corporate strategy has been discussed in prior research, mostly at a broad conceptual level with relatively little empirical validation. This paper uses data from a longitudinal study of buyer‐supplier relationships to evaluate the impact from firms' recent initiatives in developing strategic supplier alliances on the role played by the supply management effort in the corporate hierarchy. Contrary to anticipated results, the use of an alliance approach did not lead to any appreciable improvement in status and respect for supply management's role in developing corporate strategy. While several suggestions are offered to explain these results, the major conceptual models of supply‐chain strategy are reassessed and a more appropriate and grounded framework for study is proposed. Further research is called for to empirically verify the link between strategic consideration for supply issues and firm success.
Lipase activities of microbial isolates from soil contaminated with crude oil after bioremediation (2008)

This study involving assessment of the enzyme lipase as indicator of microbial degradation of crude oil was carried out using indigenous and exogenous soil microorganism. Standard microbiological, physiological and biochemical methods were adopted. Result obtained revealed Edwardsiella tarda, Bacterium aliphaticum, Bacillus megaterium, Bacillus cereus, Pseudomonas maltiphilia, Fusarium vertiaculloide, Botryodiphodia thiobroma, Fusiarum oxysporum, Cryptococcus neofomas, Aspergillus niger and Candida tropicalis as organisms indigenous to soil that have the potential to degrade crude oil. While biochemical analysis revealed that except B. aliphaticum which had lipase activity of 3.99 i/ml, fungal isolates generally recorded higher lipase activities than bacterial isolates. A. niger showed the highest lipase activity of 4.00 i/ml while P. maltophilia gave the least activity of 0.45 i/ml after 6 weeks of remediation. The findings have possible industrial and environmental implications especially towards developing a bioremediation protocol at the enzymatic level.
Differential tonic influence of lateral habenula on prefrontal cortex and nucleus accumbens dopamine release (2008)

Conditions of increased cognitive or emotional demand activate dopamine release in a regionally selective manner. Whereas the brief millisecond response of dopamine neurons to salient stimuli suggests that dopamine's influence on behaviour may be limited to signalling certain cues, the prolonged availability of dopamine in regions such as the prefrontal cortex and nucleus accumbens is consistent with the well described role of dopamine in maintaining motivation states, associative learning and working memory. The behaviourally elicited terminal release of dopamine is generally attributed to increased excitatory drive on dopamine neurons. Our findings here, however, indicate that this increase may involve active removal of a tonic inhibitory control on dopamine neurons exerted by the lateral habenula (LHb). Inhibition of LHb in behaving animals transiently increased dopamine release in the prefrontal cortex, nucleus accumbens and dorsolateral striatum. The inhibitory influence was more pronounced in the nucleus accumbens and striatum than in the prefrontal cortex. This pattern of regional dopamine activation after LHb inhibition mimicked conditions of reward availability but not increased cognitive demand. Electrical or chemical stimulation of LHb produced minimal reduction of extracellular dopamine, suggesting that in an awake brain the inhibition associated with tonic LHb activity represents a near-maximal influence on dopamine neurotransmission. These data indicate that LHb may be critical for functional differences in dopamine neurons by preferentially modulating dopamine neurons that project to the nucleus accumbens over those neurons that primarily project to the prefrontal cortex.
Simple 3D Glyphs for Spatial Multivariate Data (2006)

We present an effort to evaluate the possible utility of a new type of 3D glyphs intended for of multivariate spatial data. They are based on results from vision research suggesting that our perception of 3D structure is distorted and imprecise relative to the actual scene before us (e.g., metric 3D structure in visualizations by M. Lind et al. (2003)); only a class of qualitative properties of the scene is perceived with accuracy. These properties are best characterized as being invariant over affine but not Euclidean transformations. They are related, but not identical to, the non-accidental properties (NAPs) described by Lowe in perceptual organization and visual (1984) on which the notion of geons is based in recognition by components - a theory of image understanding by I. Biederman (1987). A large number of possible 3D glyphs for the visualization of spatial data can be constructed using such properties. One group is based on the local sign of surface curvature. We investigated these properties in a visualization experiment. The results are promising and the implications for visualization are discussed.
Spectroscopic Determination of Methanol Content in Alcoholic Drinks (2014)

The aim of this paper is to introduce an innovative method for measuring the concentration of methanol in alcoholic beverages. The novel approach consists in using Raman spectroscopic data for methanol content detection. Raman spectroscopy is a powerful method for material identification giving information about the structure of examined sample. This analytical method enables rapid, noncontact and non-destructive analysis that can be performed through the glass. The method for quantitative determination of methanol in alcoholic beverages has been developed on the basis of diverse Raman spectra for methanol and ethanol, their mathematical processing and using PLS regression method for the calibration and prediction model of methanol. Development of this new method is related to the massive methanol poisonings which occurred in the Czech Republic in September 2012. A large amount of harmful toxic alcoholic drinks containing methanol in quantities many times over legal limit was illegally distributed. This event led up to serious problems with poisoned people and the losses in lives. However, it can be assumed the problems may occur in the future since about a third of the defective alcohol has not been traced. The detection limit of the method lies below the permitted and safe amount of methanol in the beverages regulated by the European Parliament and the Council.
X-Ray Diffraction by Multilayered Thin-Film Structures and Their Diffusion (1967)

Five orders of soft x-ray diffraction by multilayered thin-film structures of Fe and Mg have been observed. The structures consisted of as many as 200 layers of Fe separated by Mg layers, providing layer spacings of 30–50 Å. The diffracting characteristics have been measured for the wavelength range 8.34 to 23.7 Å (AlKα to OKα). The integrated diffracted intensities from Fe–Mg layered structures and multilayered lead stearate soap-film structures are shown to be comparable. A diffracted x-ray peak intensity to background ratio of 80 and a resolution (λ/Δλ) of 25 have been observed for the diffraction of OKα radiation by the Fe–Mg structures. No diffusion in the Fe–Mg layers was detected at room temperature. The diffracted x-ray intensity from similar Au–Mg layered structures decreased to one-half in 15 days at room temperature because of interdiffusion. Diffusion in the Au–Mg layered system may be described by an effective interdiffusion constant that satisfies the equation Deff=4.3×10−9 exp[−18.3 kcal/(RT)] cm2 sec−1 for the temperature range 23–100°C. For Fe–Mg layered structures an effective interdiffusion constant Deff=7.9×10−20 cm2 sec−1 was measured at 260°C.
Simulations of Laser-Induced Glass Formation in Ag−Cu Nanoparticles (2008)

Using molecular dynamics simulations, we have simulated the rapid cooling experienced by bimetallic nanoparticles following laser excitation at the plasmon resonance and find evidence that glassy beads, specifically Ag−Cu bimetallic particles at the eutectic composition (60% Ag, 40% Cu), can be formed during these experiments. The bimetallic nanoparticles are embedded in an implicit solvent with a viscosity tuned to yield cooling curves that match the experimental cooling behavior as closely as possible. Because the nanoparticles have a large surface-to-volume ratio, experimentally realistic cooling rates are accessible via relatively short simulations. The presence of glassy structural features was verified using bond orientational order parameters that are sensitive to the formation of local icosahedral ordering in condensed phases. As the particles cool from the liquid droplet state into glassy beads, a silver-rich monolayer develops on the outer surface and local icosahedra can develop around the silver atoms in this monolayer. However, we observe a strong preference for the local icosahedral ordering around the copper atoms in the particles. As the particles cool, these local icosahedral structures grow to include a larger fraction of the atoms in the nanoparticle, eventually leading to a glassy nanosphere.
Digital forensic data and intelligence: Using data reduction to enable intelligence analysis (2015)

Terrorists, organised crime groups, and other criminals make substantial use of technology to aid their causes and commit crimes. The ability to silo their activities and maintain individual groups with minimal interconnections assists to hide their activities. The growth of technology, data volume, user storage, and connectivity, further assists to camouflage their activity. At the same time, there is a growing volume of digital forensic data from computers and devices seized by enforcement agencies, resulting in a pool of potential intelligence information which may hold the key to uncovering organisations endeavouring to mask their activity. The volume of data seized can be overwhelming, and present a barrier to intelligence analysis due to storage costs and processing time. A methodology which can reduce the volume of digital forensic data to enable timely search and review will assist with a process of gaining intelligence from the growing volume of digital forensic data. A process of data reduction of digital forensic data has demonstrated an ability to reduce storage demands. This data reduction method enables the storage of extracts of many devices and computer data, and assists with indexing, searching, processing, and reviewing in a timely manner.
Das asymmetrische Einschlußgitter des Harnstoffs, II. Konfigurativ stetige Gitterzuordnung der Gastmoleküle (1973)

Abstract Einem bestimmten Antipoden ist erfahrungsgemäß eine der beiden Spiegelbildformen des Harnstoffeinschlußgitters zugeordnet. Diese Zuordnung ist für Glieder einer homologen Reihe häufig die gleiche. Auch Glieder aus verschiedenen homologen Reihen, die einander der Gestalt nach gleichen, sind im allgemeinen bei gleicher Konfiguration dem gleichen Gitter zugeordnet. Durch Ermittlung der Gitterzuordnungen werden die Reihen der α‐Methyl‐, α‐Chlor‐, α‐Brom‐, α‐Amino‐ und α‐Mercaptocarbonsäuren, sowie zwei Reihen β‐substituierter Carbonsäuren auf ihre relative Konfiguration untersucht und konfigurativ miteinander verknüpft, wobei die Ergebnisse die Erwartungen bestätigen. Durch Ermittlung der Gitterzuordnung ist entdeckt worden, daß in der homologen Reihe der β‐Chlorfettsäuren zwischen L ‐β‐Chlorvaleriansäure und L ‐β‐Chlorcapronsäure das Vorzeichen der Drehung wechselt. – α‐Hydroxyfettsäuren fügen sich nicht in die Regel. Bei gleicher Konfiguration sind sie dem Einschlußgitter zugeordnet, das dem der fünf anderen Reihen α‐substituierter Säuren entgegengesetzt ist.

Reflection Symmetry Detection Using Locally Affine Invariant Edge Correspondence (2015)

Reflection symmetry detection receives increasing attentions in recent years. The state-of-the-art algorithms mainly use the matching of intensity-based features (such as the SIFT) within a single image to find symmetry axes. This paper proposes a novel approach by establishing the correspondence of locally affine invariant edge-based features, which are superior to the intensity based in the aspects that it is insensitive to illumination variations, and applicable to textureless objects. The locally affine invariance is achieved by simple linear algebra for efficient and robust computations, making the algorithm suitable for detections under object distortions like perspective projection. Commonly used edge detectors and a voting process are, respectively, used before and after the edge description and matching steps to form a complete reflection detection pipeline. Experiments are performed using synthetic and real-world images with both multiple and single reflection symmetry axis. The test results are compared with existing algorithms to validate the proposed method.
Quick‐change automation for shoe manufacture (1996)

Describes some of the successful innovations to be seen at Unishoe (Universal Shoe Machine Company Limited), such as a fully automated sole preparation line; a stress reliever lamp for removing creases from shoe uppers; machines for fitting metal shanks to the “shankboards” for stiffening insoles; and machines for conditioning and lasting uppers into shape.
A novel approach to the speaker identification over telephone networks (1993)

The authors propose a channel equalization approach to overcome the channel variation in speaker identification over a telephone system. A set of inverse channel spectra is chosen to form a basis for generating the estimated channel equalization filter. When a short utterance goes through the basis filters, the coefficients of a convex combination are produced automatically so that a channel equalization filter is generated to compensate the channel variation embedded in the speech signal. A neural network is used to optimize the coefficients in convex combination. For the case of using a 100-speaker database, an average error rate of 5.2% can be achieved in simulation.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>

A preliminary study comparing the use of allogenic chondrogenic pre‐differentiated and undifferentiated mesenchymal stem cells for the repair of full thickness articular cartilage defects in rabbits (2011)

Chondrogenic differentiated mesenchymal stem cells (CMSCs) have been shown to produce superior chondrogenic expression markers in vitro. However, the use of these cells in vivo has not been fully explored. In this study, in vivo assessment of cartilage repair potential between allogenic-derived chondrogenic pre-differentiated mesenchymal stem cells and undifferentiated MSCs (MSCs) were compared. Bilateral full thickness cartilage defects were created on the medial femoral condyles of 12 rabbits (n = 12). Rabbits were divided into two groups. In one group, the defects in the right knees were repaired using alginate encapsulated MSCs while in the second group, CMSCs were used. The animals were sacrificed and the repaired and control knees were assessed at 3 and 6 months after implantation. Quantitative analysis was performed by measuring the Glycosaminoglycans (GAGs)/total protein content. The mean Brittberg score was higher in the transplanted knees as compared to the untreated knee at 6 months (p < 0.05). Quantitative analysis of GAGs was consistent with these results. Histological and immunohistochemical analysis demonstrated hyaline-like cartilage regeneration in the transplanted sites. Significant differences between the histological scores based on O'Driscoll histological grading were observed between contralateral knees at both 3 and 6 months (p < 0.05). No significant differences were observed between the Britberg, O'Driscoll scores, and GAGs/total protein content when comparing defect sites treated with MSC and CMSC (p > 0.05). This study demonstrates that the use of either MSC or CMSC produced superior healing when compared to cartilage defects that were untreated. However, both cells produced comparable treatment outcomes.
Perpendicular and in-plane magnetic anisotropy in epitaxial Cu/Ni/Cu/Si(111) ultrathin films (1997)

Epitaxial ultrathin Cu/Ni/Cu films with Ni thickness in the range 1.5--6 nm have been grown by UHV evaporation on the $\mathrm{Si}(111)\ensuremath{-}7\ifmmode\times\else\texttimes\fi{}7$ surface. In situ characterization made by low-energy electron diffraction and Kikuchi electron diffraction revealed that both Ni and Cu films grow epitaxially on Si, with a (111) orientation and with their (1\ifmmode\bar\else\textasciimacron\fi{}10) axis parallel to the (12\ifmmode\bar\else\textasciimacron\fi{}1) axis of the Si substrate. Magneto-optical Kerr effect measurements performed at room temperature have shown that the preferential direction of magnetization lies in the film plane for Ni thickness above 3 nm, while it is perpendicular to the film plane for lower thickness. Brillouin light scattering was then exploited to study the spin-wave dispersion as a function of both the applied magnetic field and the wave vector direction on the surface plane. In order to interpret the Brillouin data, we have used a macroscopic model which takes into account both dipolar and exchange interactions, as well as bulk and interface anisotropy for the (111) plane of a cubic crystal. This enabled us to determine, in addition to the other magnetic parameters, both the in-plane and the out-of-plane anisotropy constants. The observed dependence of these constants on the film thickness indicates that the magnetic anisotropy is mainly of magnetoelastic origin.

Enantioselective Organocatalytic Intramolecular Diels−Alder Reactions. The Asymmetric Synthesis of Solanapyrone D (2005)

The first direct enantioselective organocatalytic intramolecular Diels-Alder reaction has been accomplished. The use of iminium catalysis has provided a new catalytic strategy for the enantioselective [4 + 2] cycloisomerization of a wide variety of tethered diene-enal systems. The use of imidazolidinones 1 and 2 as the asymmetric catalysts has been found to mediate the enantioselective construction of [4.4.0] and [4.3.0] ring systems. Application of this methodology to the highly efficient asymmetric synthesis of the marine metabolite solanpyrone D has also been accomplished. A diverse spectrum of aldehyde substrates can also be accommodated in this new organocatalytic transformation. Importantly, this technology has been utilized to execute the first enantioselective, catalytic Type II IMDA reaction.
Molecular Simulation Study on the Separation of Xylene Isomers in MIL-47 Metal−Organic Frameworks (2009)

The separation performance of the metal−organic framework MIL-47 for xylene isomers was studied by Monte Carlo simulations in the grand-canonical ensemble. The experimental adsorption isotherms of xylene isomers in MIL-47 between 343 and 423 K were reproduced by using force fields available in the literature. Mixture isotherms were computed and compared with the mixture isotherms predicted by using pure component adsorption data and the ideal adsorption solution theory. This theory accurately predicts mixture isotherms of xylene isomers in MIL-47. the ideal adsorption sorption theory was further employed to calculate the separation factors of xylene isomers in MIL-47. The order of preferential adsorption was found to be ortho > para > meta. The adsorption selectivity was found to increase with pressure, and the results showed a good agreement with the experimental data available. Henry coefficients and low coverage heats of adsorption and adsorption entropies were computed at 543 K showing an excellent agreement with experiments. It was found that the reason for adsorption selectivity is the interaction of CH3 groups of neighboring molecules at high loadings, mainly for molecules adsorbed on the same wall of the MIL-47 channels.
Comparison of Volatile Generation in Serine/Threonine/Glutamine−Ribose/Glucose/Fructose Model Systems (1999)

Thermal generation of volatiles in nine model reactions was studied and compared. Each of the model systems contained one amino acid and one monosaccharide. The amino acid was serine, threonine, or glutamine, and the monosaccharide was ribose, glucose, or fructose. More unsubstituted pyrazine was generated in serine-sugar systems than threonine-sugar systems. The formation of several furfuryl-substituted pyrazines and pyrroles was observed in some of the studied systems. Total pyrazines were generated more in glutamine-containing systems than in serine- and threonine-containing systems, and the reverse was true for generation of furfuryl-substituted compounds. Acetylpyrazine was generated in serine/threonine/glutamine-glucose and serine/glutamine-fructose systems.
