Supramolecular organization of pi-conjugated molecules monitored by single-walled carbon nanotubes (2015)

Photoactive pi-conjugated molecules (quaterthiophene and phthalocyanine) are either encapsulated into the hollow core of single-walled carbon nanotubes or noncovalently stacked at their outer surface in order to elaborate hybrid nanosystems with new physical properties, providing practical routes to fit different requirements for potential applications. We are interested in the relationship between the structure and the optoelectronic properties. The structural properties are investigated mainly by x-ray diffraction and/or transmission electron microscopy and Raman spectroscopy. We show that the supramolecular organizations of confined quaterthiophenes depend on the nanocontainer size, whereas phthalocyanine encapsulation leads to the formation of a one-dimensional phase for which the angle between the molecule ring and the nanotube axis is close to 32 deg. Confined phthalocyanine molecules display Raman spectra hardly altered with respect to the bulk phase, suggesting a rather weak interaction with the tubes. In contrast, the vibrational properties of the molecules stacked at the outer surface of tubes display important modifications. We assume a significant curvature of the phthalocyanine induced by the interaction with the tube walls and a change of the central atom position within the molecular ring, in good agreement with our density functional theory calculations.
Crystal structure and morphology control of molybdenum carbide nanomaterials synthesized from an amine–metal oxide composite (2013)

Multiple phases of molybdenum carbide have been synthesized using a unique amine-metal oxide composite material. By combining molybdenum oxide and an amine, a templated precursor is formed which can be thermally decomposed to form molybdenum carbide with control over the structure and morphology of the nano-sized products.
A STABILITY RESULT IN FIXED POINT THEORY (2005)

Let K be a compact convex subset of a Banach space. We consider a complete metric space of all the continuous self-mappings of K and show that a typical element of this space (in the sense of Baire category) has a fixed point which is stable under small perturbations of the mapping.

Red–green–blue photopumped lasing from ZnCdMgSe/ZnCdSe quantum well laser structures grown on InP (1998)

Room-temperature optical pumped lasing emission in the red, green, and blue has been obtained from ZnCdMgSe/ZnCdSe quantum well (QW) laser structures grown on InP substrates. The structures are nearly identical, except for variations in the thickness and/or composition of the QW layer. No other single set of semiconductor materials has been demonstrated whose structures are pseudomorphic on one single substrate, and produces light emitters throughout the entire visible range. Our results demonstrate the potential for these materials as integrated full color display devices.
Enantioselective Cyclopropanation of Allylic Alcohols with Dioxaborolane Ligands:  Scope and Synthetic Applications (1998)

A very effective chiral controller has been found for the conversion of allylic alcohols into the corresponding enantiomerically enriched cyclopropanes using bis(iodomethyl)zinc. A variety of chiral, nonracemic cyclopropylmethanols could be obtained according to this method. This methodology was extended with success to the cyclopropanation of unconjugated and conjugated polyenes and homoallylic alcohols. The cyclopropanation of allylic carbamates has also been investigated with this system, but it was found that enantioenriched cyclopropylmethylamines are best prepared from enantioenriched cyclopropylmethanols.
Chromogranin A and pancreastatin-like immunoreactivity in human carcinoid disease (1993)

Objective: To evaluate chromogranin A (CgA) and pancreastatin-like immunoreactivity (PST-LI) as tumor markers in human carcinoid disease, compared with urinary excretion of 5-hydroxyindole acetic acid (5-HIAA), and to evaluate their role as indicators of survival. Patients and methods: Urinary 5-HIAA excretion was determined by a spectrophotometric method, while serum CgA and PST-LI were determined by radioimmunoassay methods in 38 patients with midgut, 10 with foregut and one with hindgut carcinoids. Results: In midgut carcinoid patients levels of 5-HIAA, CgA and PST-LI were raised by 76, 82 and 76%, respectively. The median CgA level in midgut carcinoid patients was significantly higher than in the controls (193 compared with 12ng/ml; P<0.01). In the midgut carcinoid patients, the median CgA value was significantly higher in women who died (1990 ng/ml) than in those who survived (46ng/ml; P<0.01), and significantly higher than in men, either survivors or non-survivors. The median PST-LI value was significantly higher in midgut carcinoid patients than in the control group (2282 compared with 33 pg/ml; P< 0.01). In women, the median PST-LI level was significantly higher in non-survivors than in survivors (9088 compared with 1337 pg/ml; P<0.01), and significantly higher than in male survivors and non-survivors. In foregut carcinoid patients, levels of CgA, PST-LI and 5-HIAA were increased in nine, eight and one patient, respectively. The median CgA and PST-LI levels in the foregut group were similar to the midgut group. Conclusion: CgA and PST-LI are useful markers in the diagnosis of both midgut and foregut carcinoids. They are as good as, or more sensitive than, 5-HIAA.

Nanotechnology in the service of corrosion science: considering graphene and derivatives as examples (2022)

Nanotechnology is a branch of science and engineering that involves the synthesis, modification, characterisation and application of nanoscale materials in diverse fields. They provide excellent surface coverage and are successfully used as corrosion inhibitors. However, most of the nanomaterials are not effective and require special treatments or modifications for proper anticorrosive activities. The present review article features the current approaches and practices that have been adopted to enhance the anticorrosive performance of nanoscale materials. One of the most growing interests in this direction is the use of covalently and non-covalently functionalised nanomaterials. The functionalised nanomaterials show remarkable improvement in corrosion protection performance. The covalently functionalised nanomaterials show better dispersibility and thereby better efficiency in aqueous electrolytes. In the anticorrosive formulations, nanomaterials avoid the penetration of corrosive species and thereby increase durability and corrosion inhibition. The nanomaterials in anticorrosive formulations also enhance weathering resistance, UV resistance, mechanical performance, thermal stability and hydrophobic property.
The coordinated arctic acoustic thermometry experiment—CAATEX (2022)

The coordinated arctic acoustic thermometry experiment (CAATEX) was a joint U.S.-Norwegian trans-Arctic acoustic propagation experiment with a design comparable to the 1994 TransArctic Propagation (TAP) experiment. The goal was to measure the changes in low-frequency sound propagation due to changes in ocean heat content and salinity, and ice conditions. Two 35 Hz acoustic transceiver moorings, one in the Nansen Basin and one in the Beaufort Sea, were deployed along with four other receiving moorings. All six moorings were equipped with vertical hydrophone arrays, recording transmissions every 36 h from fall 2019 to fall 2020. Each mooring also recorded temperature and salinity time series along the vertical extent of the hydrophone arrays, ice thickness using an upward-looking sonar, and ocean bottom pressure. The acoustic travel-times allow comparison of present-day heat content to the 1994 measurement, but there are several other points of comparison that are sensitive to environmental changes. These include transmission loss, acoustic scattering, and the acoustic arrival structure. These measurements of ocean and ice processes, and the acoustic propagation and ambient sound will improve our ability to monitor, communicate, and navigate in the Arctic Ocean.
Spiral metamaterial for tunable circular dichroism (2013)

We propose an electrostatically actuated spiral structures as a metamaterial for circularly polarized light in Terahertz (THz) frequency. Actuation of the spiral structures changes their geometry, and produces a tunable chirality resulting in circular dichroism, which is the differential absorption between the left and right circularly polarized light. Results of the THz-spectroscopy confirmed that the ON/OFF of circular dichroism was achieved with the proposing structures.
Slicing java programs that throw and catch exceptions (2003)

Exceptions are the preferred method for error handling in object-oriented languages like Java. Current program-slicing algorithms do not correctly deal with exception-handling constructs, because they do not account for the additional control and data dependences introduced by exceptions. This paper extends previous work on program slicing using the system dependence graph (SDG) to support slicing programs with exceptions.
Charge noise acting on graphene double quantum dots in circuit quantum electrodynamics architecture (2018)

We investigate the dephasing mechanisms induced by the charge noise and microwave heating effect acting on a graphene double quantum dot (DQD) capacitively coupled to a microwave resonator. The charge noise is obtained from DC transport current, and its contribution to dephasing is simultaneously determined by the amplitude response of the microwave resonator. A lowfrequency 1/f-type noise is demonstrated to be the dominant factor of the dephasing of graphene DQD. Furthermore, when the applied microwave power is larger than −90 dBm, the dephasing rate of graphene DQD increases rapidly with the increase of microwave power, and fluctuates slightly with the applied microwave power smaller than −90 dBm. Our results can be applied to suppress the impeditive influence on the dephasing of graphene-based devices associated with microwave input in the perspective investigations.
Reaction of carbenoid species diazomethane decomposition over zeolite ZSM-5 (1985)

Decomposition of diazomethane over zeolite ZSM-5 gives ethene and propane as the major products; this supports the existence of carbenoid intermediates proposed in methanol conversion into ethene and higher hydrocarbons over this catalyst.
[Mediastinal bronchogenic cyst associated with a multiple malformation syndrome]. (1993)

The authors report a case of a patient presenting with a bronchogenic mediastinal cyst, which presented as a super-infection of the cyst. The cyst was associated with malformation of the cervical vertebra, cardiovascular abnormalities and congenital deafness, placing this in the group of rare complex polymalformation syndrome with Klippel-Feil Syndrome. The authors also stress the value of computed tomography, and above all of nuclear magnetic resonance in the analysis of mediastinal tumours and in particular, of bronchogenic cysts.
Biocompatibility of Immobilized Aligned Carbon Nanotubes (2011)

In vivo host responses to an electrode-like array of aligned carbon nanotubes (ACNTs) embedded within a biopolymer sheet are reported. This biocompatibility study assesses the suitability of immobilized carbon nanotubes for bionic devices. Inflammatory responses and foreign-body histiocytic reactions are not substantially elevated when compared to negative controls following 12 weeks implantation. A fibrous capsule isolates the implanted ACNTs from the surrounding muscle tissue. Filamentous nanotube fragments are engulfed by macrophages, and globular debris is incorporated into the fibrous capsule with no further reaction. Scattered leukocytes are observed, adherent to the ACNT surface. These data indicate that there is a minimal local foreign-body response to immobilized ACNTs, that detached fragments are phagocytosed into an inert material, and that ACNTs do not attract high levels of surface fouling. Collectively, these results suggest that immobilized nanotube structures should be considered for further investigation as bionic components.
CXCR4-Targeted PET Imaging of Central Nervous System B-Cell Lymphoma (2020)

C-X-C chemokine receptor 4 (CXCR4) is a transmembrane chemokine receptor involved in growth, survival, and dissemination of cancer, including aggressive B-cell lymphoma. MRI is the standard imaging technology for central nervous system (CNS) involvement of B-cell lymphoma and provides high sensitivity but moderate specificity. Therefore, novel molecular and functional imaging strategies are urgently required. <b>Methods:</b> In this proof-of-concept study, 11 patients with lymphoma of the CNS (8 primary and 3 secondary involvement) were imaged with the CXCR4-directed PET tracer <sup>68</sup>Ga-pentixafor. To evaluate the predictive value of this imaging modality, treatment response, as determined by MRI, was correlated with quantification of CXCR4 expression by <sup>68</sup>Ga-pentixafor PET in vivo before initiation of treatment in 7 of 11 patients. <b>Results:</b><sup>68</sup>Ga-pentixafor PET showed excellent contrast with the surrounding brain parenchyma in all patients with active disease. Furthermore, initial CXCR4 uptake determined by PET correlated with subsequent treatment response as assessed by MRI. <b>Conclusion:</b><sup>68</sup>Ga-pentixafor PET represents a novel diagnostic tool for CNS lymphoma with potential implications for theranostic approaches as well as response and risk assessment.
Tube leukocyte adherence inhibition assay for the detection of anti‐tumour immunity. I. Monocyte is the reactive cell (1976)

Peripheral blood leukocytes (PBL) from breast cancer patients with early or localized cancer fail to adhere to glass in the presence of breast cancer extract. The same leukocytes do not react to unrelated tumour extracts. Enrichment and depletion of certain PBL populations from patients with apparently localized breast cancer indicated that the indicator and/or reactive cell manifesting non-adherence in the presence of appropriate tumour antigen was phagocytic, glass adherent in the absence of tumour antigen and had cell surface Fc-receptors. The cell involved, therefore, appears to be the circulating monocyte. These results show that in the tube LAI assay, the peripheral blood monocyte appears to react directly with the tumour antigen resulting in a loss of its property of adherence to glass.
Power Amplifier Switching (PAS) for Energy Efficient Systems (2012)

We propose a power amplifier (PA) switching/selection (PAS) method to improve the energy efficiency (EE) of a transmit antenna selection and maximum ratio combining (TAS-MRC) system. A PAS transmitter has a PA bank consisting of multiple dissimilar PAs, which operate with different output power levels, and selects the most efficient PA and its power level that satisfies a target rate. If there is no PA supporting the target rate, the transmitter is set to an off-mode (i.e., all PAs are turned off). The receiver feeds back the choice of PA and its power level to the transmitter, similar to the feedback in a conventional power control system with a single PA. Numerical results show that the system EE can be improved by using the PAS. This letter is the first study to investigate and verify the potential capability of PAS for the system EE improvement in wireless communications.
Electrochemically Triggered Michael Addition on the Self-Assembly of 4-Thiouracil:  Generation of Surface-Confined Redox Mediator and Electrocatalysis (2007)

Generation of a surface-confined redox mediator (RM) by an electrochemically triggered Michael addition reaction and the electrocatalytic properties of the mediator are described. Electrogenerated o-quinone undergoes Michael addition reaction with the self-assembled monolayer (SAM) of 4-thiouracil (4-TU) on a gold (Au) electrode and yields a surface-confined RM, 1-(3,4-dihydroxyphenyl)-4-mercapto-1H-pyrimidin-2-one (DPTU). The Michael addition reaction depends on the electrolysis potential and time, solution pH, and concentration of catechol (CA) used in the reaction. The redox mediator, DPTU, exhibits reversible redox response, characterstic of a surface-confined species at approximately 0.22 V in neutral pH. The anodic peak potential of DPTU shifts by 58+/-2 mV while changing the solution pH by one unit, suggesting that protons and electrons taking part in the redox reaction are in the ratio of 1:1. The apparent rate constant (ksapp) for the heterogeneous electron-transfer reaction of the RM was determined to be 114+/-5 s-1. The surface coverage (Gamma) of DPTU on the electrode surface was 8.2+/-0.1x10(-12) mol/cm2. DPTU shows excellent electrocatalytic activity toward oxidation of reduced nicotinamide adenine dinucleotide (NADH) with activation overpotential, which is approximately 600 mV lower than that observed at the unmodified Au electrode. The dipositive cations in the supporting electrolyte solution amplify the electrocatalytic activity of DPTU. A 2.5-fold enhancement in the catalytic current was observed in the presence of Ca2+ or Ba2+ ions. The sensitivity of the electrode toward NADH in the presence and absence of Ca2+ ions was 0.094+/-0.011 and 0.04+/-0.0071 nA cm-2 nM-1, respectively. A linear increase in the catalytic current was obtained up to the concentration of 0.8 mM, and the electrode can detect amperometrically as low as 25 nM of NADH in neutral pH.

Collaborative marketplaces for eScience: A medical imaging use case (2014)

The development of digital imaging technology is creating extraordinary levels of accuracy that provide support for improved reliability in different aspects of the image analysis such as content-based image retrieval, image segmentation and classification. This has dramatically increased the volume and generation rates of data, which make querying and sharing non-trivial, and render centralized solutions infeasible. Moreover, in many cases this data is naturally distributed or has to be shared across multiple institutions requiring decentralized solutions. In this paper, we present a federation approach that can take advantage of advanced cyber-infrastructure (ACI) by seamlessly and securely interacting with information/data located across geographically distributed resources. We describe and evaluate the establishment of a federated marketplace across resources from UK and US in the context of collaborative research in medical imaging. We show how users from different sites can transparently access to remote data by placing computational requests in the marketplace. Moreover, we evaluate different pricing policies to demonstrate how site providers and users can benefit from such federation.
Comparing the short and ultrashort pulsed laser ablation of LiF (2004)

Pulsed laser ablation of LiF was studied using both nanosecond (ns) and femtosecond (fs) pulses at 248nm. Optical emission from electronically excited Li and F atoms in the plume of ejected material was investigated by wavelength, time and spatially resolved imaging methods. Careful analysis of images of species selected optical emission yielded estimates of the mean velocities of the Li+ ions arising in both excitation schemes (∼11 and ∼13km∕s, respectively), and highlighted the dramatic effects of radiation trapping, most notably by the reabsorption of Li(2p→2s) emission by ground state Li atoms in the ns ablation studies. Plumes formed by fs excitation are found to contain a higher fraction of energetic∕electrically excited components, including excited F atoms and ions, indicative of an explosive boiling mechanism, whereas the ablation plume resulting from ns ablation is deduced to arise primarily from thermal evaporation of the transiently heated target surface. The amount of target material removed per shot is significantly less in the case of fs excitation. The density (and size) of unwanted droplets in films grown by fs ablation is much smaller than in the case of ns ablation, especially on substrates mounted in an off-axis ablation geometry, implying that hydrodynamic sputtering is much reduced by the use of short pulses and that fs ablation must be the preferred route to forming very thin LiF coatings.
Influence of Bifurcations on Forced Oscillations in an Airway Model (1992)

Forced oscillations is a technique to determine respiratory input impedance from small amplitude sinusoidal pressure excursions introduced at the airway opening. Models used to predict respiratory input impedance typically ignore the direct effect of bifurcations on the flow, and treat airway branches as individual straight tubes placed appropriately in parallel and series. The flow within the individual tubes is assumed equivalent to that which would occur in infinitely long tubes. In this study we examined the influence of bifurcations on impedance for conditions of the forced oscillatory technique. We measured input impedance using forced oscillations in straight tubes and in an anatomically-relevant, four generation physical model of a human airway network. The input impedance measured experimentally compared well to that obtained theoretically using model predictions. The predictive scheme was based on appropriate parallel and series combinations of theoretically computed individual tube impedances, which were computed from solutions to oscillatory flow of a compressible gas in an infinitely long rigid tube. The agreement between experimental measurements and predictions indicates that bifurcations play a relatively minor direct role on the flow impedance for conditions of the forced oscillations technique. These results are explained in terms of the small tidal volumes used, whereby the axial distance traveled by a fluid particle during an oscillation cycle is appreciably smaller than branch segment lengths. Accordingly, only a small fraction of fluid particles travel through the bifurcation region, and the remainder experience an environment approaching flow in an infinite straight tube. The relevance of the study to the prediction of impedances in the human lung during forced oscillations is discussed.
