Dynamical Decoupling of Open Quantum Systems (1999)

We propose a novel dynamical method for beating decoherence and dissipation in open quantum systems. We demonstrate the possibility of filtering out the effects of unwanted (not necessarily known) system-environment interactions and show that the noise-suppression procedure can be combined with the capability of retaining control over the effective dynamical evolution of the open quantum system. Implications for quantum information processing are discussed.

Query Optimization Techniques in Microsoft SQL Server (2014)

Microsoft SQL Server is a relational database management system, having MS-SQL and Transact-SQL as primary structured programming languages. They rely on relational algebra which is mainly used for data insertion, modifying, deletion and retrieval, as well as for data access controlling. The problem with getting the expected results is handled by the management system which has the purpose of finding the best execution plan, this process being called optimization. The most frequently used queries are those of data retrieval through SELECT command. We have to take into consideration that not only the select queries need optimization, but also other objects, such as: index, view or statistics.
Magnetochromatic Microspheres: Rotating Photonic Crystals (2009)

Magnetochromatic microspheres have been fabricated through instant assembly of superparamagnetic (SPM) colloidal particles inside emulsion droplets of UV curable resin followed by an immediate UV curing process to polymerize the droplets and fix the ordered structures. When dispersed in the liquid droplets, superparamagnetic Fe(3)O(4)@SiO(2) core/shell particles self-organize under the balanced interaction of repulsive and attractive forces to form one-dimensional chains, each of which contains periodically arranged particles diffracting visible light and displaying field-tunable colors. UV initiated polymerization of the oligomers of the resin fixes the periodic structures inside the droplet microspheres and retains the diffraction property. Because the superparamagnetic chains tend to align themselves along the field direction, it is very convenient to control the orientation of such photonic microspheres and, accordingly, their diffractive colors, by changing the orientation of the crystal lattice relative to the incident light using magnetic fields. The excellent stability together with the capability of fast on/off switching of the diffraction by magnetic fields makes the system suitable for applications such as color display, rewritable signage, and sensors. As a simple demonstration, we have fabricated a display unit that has on/off bistable states by embedding the magnetochromatic microspheres in a matrix that can thermally switch between solid and liquid phases.
A Review of Adhesion Promotion Techniques for Solid Timber Substrates (2008)

The use of primers, coupling agents, and other surface treatments to enhance adhesion is now common in the aerospace, automotive, and plastics industries, where they are used to develop highly durable bonds to metals, advanced composites, ceramics, and plastics. However, such treatments are virtually non-existent in the wood products industry although they could solve important adhesion problems. In particular, adhesion promoters can enhance the environmental durability of epoxy bonded joints, and they can enhance the reliability of bonds to timber treated with wood preservatives. A review of current findings is provided that attempts to gather the scarce and disperse information available in the literature about adhesion promotion techniques for bonded solid timber joints. A general overview of the research needs on this topic is also given.
Towards a systematic understanding of the effects of velocity model errors on depth and time migration of seismic data (1987)

The analysis and interpretation of seismic data takes place in three fundamental seismic domains. These are unmigrated time, which corresponds to normal incidence or stacked seismic data, migrated depth, which corresponds to the physical structure of the earth, and finally migrated time, a non-physical intermediate domain. Simplified models may be derived from the seismic data and transformed between the domains using ray theoretical techniques, specifically image rays and normal rays. This ray-theoretical modelling is extremely cheap and may be used to define the velocity zones for depth or time wave-theoretical migration of the seismic data itself. Furthermore, techniques can be developed to analyse the effects of velocity errors on time and depth migration. The positional error zones that result from velocity uncertainty are complex and often quite surprising, in that they relate to the local geology in a way that is often difficult to imagine intuitively. These velocity uncertainty analyses should be an invaluable aid to the interpreter in determining migration velocity sensitivity and, in particular, in placing reliable confidence limits on the spatial predictions made from both time- and depth-migrated seismic data.
Treatment and outcomes of metastatic colorectal cancer in <scp>A</scp>ustralia: defining differences between public and private practice (2014)

Significant differences in baseline characteristics were noted for private versus public patients. However, these do not explain the higher rates of treatment delivery in the private setting, which likely contributed towards the observed survival difference. Further studies are required to determine if the increased likelihood of intervention in the private setting is driven by patient, clinician and/or institutional factors.
The Carotenoid Cleavage Dioxygenase 1 Enzyme Has Broad Substrate Specificity, Cleaving Multiple Carotenoids at Two Different Bond Positions (2008)

In many organisms, various enzymes mediate site-specific carotenoid cleavage to generate biologically active apocarotenoids. These carotenoid-derived products include provitamin A, hormones, and flavor and fragrance molecules. In plants, the CCD1 enzyme cleaves carotenoids at 9,10 (9',10') bonds to generate multiple apocarotenoid products. Here we systematically analyzed volatile apocarotenoids generated by maize CCD1 (ZmCCD1) from multiple carotenoid substrates. ZmCCD1 did not cleave geranylgeranyl diphosphate or phytoene but did cleave other linear and cyclic carotenoids, producing volatiles derived from 9,10 (9',10') bond cleavage. Additionally the Arabidopsis, maize, and tomato CCD1 enzymes all cleaved lycopene to generate 6-methyl-5-hepten-2-one. 6-Methyl-5-hepten-2-one, an important flavor volatile in tomato, was produced by cleavage of the 5,6 or 5',6' bond positions of lycopene but not geranylgeranyl diphosphate, zeta-carotene, or phytoene. In vitro, ZmCCD1 cleaved linear and cyclic carotenoids with equal efficiency. Based on the pattern of apocarotenoid volatiles produced, we propose that CCD1 recognizes its cleavage site based on the saturation status between carbons 7 and 8 (7' and 8') and carbons 11 and 12 (11' and 12') as well as the methyl groups on carbons 5, 9, and 13 (5', 9', and 13').
Towards visually-grounded spoken language acquisition (2003)

A characteristic shared by most approaches to natural language understanding and generation is the use of symbolic representations of word and sentence meanings. Frames and semantic nets are examples of symbolic representations. Symbolic methods are inappropriate for applications which require natural language semantics to be linked to perception, as is the case in tasks such as scene description or human-robot interaction. This paper presents two implemented systems, one that learns to generate, and one that learns to understand visually-grounded spoken language. These implementations are part of our on-going effort to develop a comprehensive model of perceptually-grounded semantics.

Design, Implementation And Analysis Of Composite Material Dampers For Turning Operations (2009)

This paper introduces a novel design for boring bar with enhanced damping capability. The principle followed in the design phase was to enhance the damping capability minimizing the loss in static stiffness through implementation of composite material interfaces. The newly designed tool has been compared to a conventional tool. The evaluation criteria were the dynamic characteristics, frequency and damping ratio, of the machining system, as well as the surface roughness of the machined workpieces. The use of composite material in the design of damped tool has been demonstrated effective. Furthermore, the autoregressive moving average (ARMA) models presented in this paper take into consideration the interaction between the elastic structure of the machine tool and the cutting process and can therefore be used to characterize the machining system in operational conditions.
Immunization with the Yersiniabactin Receptor, FyuA, Protects against Pyelonephritis in a Murine Model of Urinary Tract Infection (2013)

Urinary tract infections (UTI) are common and represent a substantial economic and public health burden. Roughly 80% of these infections are caused by a heterogeneous group of uropathogenic Escherichia coli (UPEC) strains. Antibiotics are standard therapy for UTI, but a rise in antibiotic resistance has complicated treatment, making the development of a UTI vaccine more urgent. Iron receptors are a promising new class of vaccine targets for UTI, as UPEC require iron to colonize the iron-limited host urinary tract and genes encoding iron acquisition systems are highly expressed during infection. Previously, three of six UPEC siderophore and heme receptors were identified as vaccine candidates by intranasal immunization in a murine model of ascending UTI. To complete the assessment of iron receptors as vaccine candidates, an additional six UPEC iron receptors were evaluated. Of the six vaccine candidates tested in this study (FyuA, FitA, IroN, the gene product of the CFT073 locus c0294, and two truncated derivatives of ChuA), only FyuA provided significant protection (P = 0.0018) against UPEC colonization. Intranasal immunization induced a robust and long-lived humoral immune response. In addition, the levels of FyuA-specific serum IgG correlated with bacterial loads in the kidneys [Spearman's rank correlation coefficient ρ(14) = -0.72, P = 0.0018], providing a surrogate of protection. FyuA is the fourth UPEC iron receptor to be identified from our screens, in addition to IutA, Hma, and IreA, which were previously demonstrated to elicit protection against UPEC challenge. Together, these iron receptor antigens will facilitate the development of a broadly protective, multivalent UTI vaccine to effectively target diverse strains of UPEC.
Services for Knowledge Resource Sharing &amp; Management in an Open Source Infrastructure for Lifelong Competence Development (2007)

Access to learning information is still restricted due to the lack of technical and semantic interoperability, locking knowledge resources in disconnected islands. This situation does not provide learners with a motivating environment in which to access and share learning information. In order to target emerging needs for lifelong competence development, a flexible and open source environment for management and sharing of knowledge resources must be built on top of an infrastructure that maximizes the amount of information available, therefore integrating centralised repositories and user desktop resources as well as emergent Web 2.0 applications. This paper describes the challenges and requirements that need to be addressed and presents a set of interfaces and our current implementation of the knowledge resource sharing and management service oriented architecture.
Production of Glucose Isomerase by <i>Streptomyces flavogriseus</i> (1979)

A microorganism that produces glucose isomerase was isolated from soil and identified as a strain of Streptomyces flavogriseus. The organism produced a large quantity of glucose isomerase when grown on straw hemicellulose, xylan, xylose, and H(2)SO(4) hydrolysate of ryegrass straw. The organism produced glucose isomerase both intra- and extra-cellularly. The highest level of intracellular glucose isomerase (3.5 U/ml) was obtained in about 36 h by a culture grown on straw hemicellulose; the extracellular enzyme (1.5 U/ml) appeared in cultures grown for about 72 h. About equal levels of enzyme were produced in cultures grown on straw hemicellulose, xylan, xylose, and H(2)SO(4) hydrolysate of straw, but production of the enzyme was drastically reduced when the organism was grown on other carbon sources. As a nitrogen source, corn steep liquor produced the best results. Soy flour extract, yeast extract, and various peptones also were adequate substrates for glucose isomerase production. Addition of Mg, Mn, or Fe to the growth medium significantly enhanced enzyme production. The organism, however, did not require Co, which is commonly required by microorganisms used in the production of glucose isomerase.
Evaluation of the Proteolytic Activity of Factor D Accumulated as an Active Serine Protease in Patients with Chronic Renal Failure (1994)

Complement factor D, a complement system serine protease, circulating in vivo as its active form, accumulates in patients with chronic renal failure. The pathophysiological role of this active protease in these patients was examined by studies on activities of excess factor D on 10 synthetic peptide substrates for some usual serine proteases. The most sensitive of these substrates to factor D was Boc-Gln-Ala-Arg-MCA, which is used as a substrate for trypsin. The proteolytic activity of factor D (2.17 unit/mg/h) on this substrate was estimated to be 10(-5)-fold that of trypsin (2.18 x 10(5) unit/mg/h). The activities of factor D on other synthetic substrates were lower. Thus the proteolytic activity of factor D is considered to be very specific for its natural substrate, complement factor B bound with C3b, even when it is highly accumulated in vivo. The inhibitory effects of some serine protease inhibitors used clinically (nafamostat mesilate, sepinostat mesilate, camostat mesilate and gabexate mesilate) on the proteolytic activity of factor D on its natural substrate, factor B, were also investigated. Of these synthetic compounds, nafamostat mesilate was the most effective inhibitor (ID50:25 microM) of the activity of factor D on factor B.
Clown Doctors as a Treatment for Preoperative Anxiety in Children: A Randomized, Prospective Study (2005)

This study shows that the presence of clowns during the induction of anesthesia, together with the child's parents, was an effective intervention for managing children's and parents' anxiety during the preoperative period. We would encourage the promotion of this form of distraction therapy in the treatment of children requiring surgery, but the resistance of medical personnel make it very difficult to insert this program in the activity of the operating room.
Optical and electrical switching in nanostructured coatings of VO 2 (2007)

Vanadium dioxide undergoes a reversible metal-insulator phase transition at about 68°C. Coatings of this compound are reflective in the infrared above this temperature, and transmissive or absorptive below it, while resistivity changes by several orders of magnitude. We present a convenient method for depositing films with nano-size grains, which are then optically and electrically characterised. Emphasis in this study is the impact of aluminum doping and grain structure. The optical hysteresis is presented and its switching range is not altered at different doping levels but the value of transition temperature Tc does shift. In contrast hysteresis in dc resistance does change with a strong correlation between the fall in resistance in the semiconductor state with doping, the drop in Tc and the electrical properties in the metal state. For grain sizes under about 180 nm the conductivity in the metal phase is not linear in temperature but is thermally activated, with activation energies ΔE dependent on both grain size G and doping level. Simple mathematical relationships are found connecting ΔE with G and with carrier density in the semiconductor state. ΔE ranges in our samples from 0.15 eV in the smallest grain sizes to around 0.06 eV. This anomalous low frequency metal response is linked to excitations that arise in the metal phase associated with transient singlet pairing on neighbouring sites. Such pairing is weakened by doping, and in large grains appears to be present but incoherent.
Motion Control in Three Dimensional Round System of Blimp Robot (2006)

Blimp robots are attractive as indoor flying robots because they can float in the air, land safely with low energy, and stay in motion for a long time compared with other flying robots. However, controlling of blimp robots is difficult, because they have nonlinear characteristics, are influenced by air streams, and is easy to be influenced of inertia. Therefore a robust and adaptive control system is needed for blimp robots. The applied research that paid its attention to the feature of indoor flying robot in recent years has prospered. Operating an indoor blimp robot for a long time is difficult for the payload is small, many batteries cannot be stacked, and the design of a thruster that has freedom and the entire blimp robot. Therefore, an autonomous charge that enables operation for a long time is needed. We developed a round orbit control to the surveillance point for an autonomous of a blimp robot. The possibility of round surveillance three dimensional orbit controls was shown
A snapshot imaging spectropolarimeter (2003)

Virtual reality in interventional radiology (1997)

SummaryApplications of virtual reality in Interventional Radiology have largely been directed towards development of simulators for teaching and for training in catheterization procedures or for demonstrating specific interventions such as angioplasty, stent placement or intra-arterial drug infusion therapy. Primary advantages of such systems are that they provide the clinician with an opportunity to practice hand-eye coordinated catheter manipulations that previously could only be achieved during actual patient studies or in the animal laboratory. Difficulties with the systems include problems relating to modeling realistic interactions between the catheter and blood vessels and difficulties in providing the clinician with a library of vascular reconstructions demonstrating pathologies from actual patient databases. Also, because the catheterization procedure is so closely linked with imaging equipment, it is a challenge to reproduce the clinical setting insofar as the clinician feels a part of the laboratory environment. Technological developments in patient image data acquisition, image reconstruction and processing should help solve the problem of creating realistic pathological vascular data sets.Keywords: interventional radiologymedical simulationcardiovascularcatheterization
Splenectomy Does Not Offer Immunological Benefits in ABO-Incompatible Liver Transplantation With a Preoperative Rituximab (2011)

Preoperative rituximab effectively decreased the anti-ABO antibodies sufficiently to prevent the AMR irrespective of splenectomy. Splenectomy does not offer any immunological benefit in ABO-I LT with preoperative rituximab.
Bacterial Flora of Chicken Carcasses Treated with High Concentrations of Chlorine (1968)

SUMMARY Laboratory experiments are described which aimed to find the effect on the initial and spoilage flora of broiler carcasses of immersion for 4 h in chilled water containing 200 or 400 p/m of free residual chlorine. Spoilage of such carcasses when held at 1° was mainly due to the normal Pseudomonas—Achromobacter type of flora, and the shelf life was extended by c. 20%. The value of such treatment is discussed.
