The preparation of polysiloxane coatings via a modified sol-gel technique (1995)

The objective of our work was to modify the traditional sol-gel method to produce polysiloxanes suitable for high-temperature-resistant coatings while avoiding the gelation/sintering process. The noted superior thermal stability of phenyl over alkyl-substituted polysiloxanes prompted us to use primarily aromatic-substituted silanes [(OR){sub 3}SiPh and (OR){sub 2}SiPh{sub 2}] as precursors in this study. Different formulations of starting materials were used to produce both homo- and co-polysiloxanes. The thermal stability and qualitative film-forming properties of these polymers were examined along with general methods ({sup 1}H NMR and FT-IR spectroscopy) of characterization.
Duodenal Injuries in Abdominal Trauma (1999)

Duodenal injuries are rare and therefore correct diagnosis and treatment is difficult. In case of penetrating trauma or hemodynamic instable patients following blunt trauma the emergent laparotomy is mandatory. CT scan is recommended in cases of hemodynamic stable patients after blunt trauma. Primary repair is the treatment of choice in the majority of duodenal injuries.

Passivation, transition width, and noise for YBCO bolometers on silicon (1999)

We are developing YBa/sub 2/Cu/sub 3/O/sub 7-x/ (YBCO) thermometers for large area bolometers that include a heater for calibration by the electrical substitution of power. Because YBCO on buffered Si is under mechanical stress and must be very thin to avoid cracking, we find it is electrically sensitive to its passivation layer. For example, passivation by SrTiO/sub 3/ raised the noise in our films by about a factor of 100. An alternative is to first cap the YBCO with Au for passivation, and then add an insulator for electrical isolation. Such devices have a narrower transition width, by a factor of 3.9. A model with a shunt resistor across the superconductor predicts a narrowing of the transition, but by less than the observed amount. The noise equivalent temperatures of our thermometers, about 4 nK Hz/sup -1/2/, are not degraded by the normal metal shunt, although the resistance is decreased. The resistance is decreased. The resistance can be raised using AgAu alloy in place of Au, with equivalent noise performance.
Mono- and Mixed-Valence Tetrathiafulvalene Semiconductors (TTF)BiI4 and (TTF)4BiI6 with 1D and 0D Bismuth-Iodide Networks (2016)

Two new compounds containing tetrathiafulvalene (TTF) cations with extended and discrete anions based on Bi and I are reported. The compound (TTF)BiI<sub>4</sub> comprises [BiI<sub>2</sub>I<sub>4/2</sub>]<sup>-</sup> chains of edge-shared octahedra that are interspersed with stacks of TTF<sup>+•</sup>. The compound (TTF)<sub>4</sub>BiI<sub>6</sub> has mixed-valence stacks of TTF and TTF<sup>+•</sup> and discrete molecules of TTF<sup>+•</sup> separated by discrete [BiI<sub>6</sub>]<sup>-3</sup> anions. The optical and electrical transport properties of these compounds are reported. Due to the mixed-valence stacks of TTF, (TTF)<sub>4</sub>BiI<sub>6</sub> is the significantly better electrical conductor than (TTF)BiI<sub>4</sub>, despite the discrete nature of the inorganic moiety.
Characterization of ethiofos absorption in the rat small intestine (1991)

The absorption characteristics of ethiofos were studied using the rat in situ intestine circulating perfusion technique. Slow absorption kinetics were observed for ethiofos with varying rates of absorption and metabolism/degradation in situ as a function of buffer and absorption enhancers. In most cases less than 10 per cent of the radiolabeled compound is lost from the circulating perfusate in 90 min. In addition, over the same time period greater than 40 per cent of the intact parent compound was lost by degradation. Much of the difference can be accounted for in the formation of the free thiol metabolite. WR-1065, suggesting ester hydrolysis or metabolic activity. Good stability was observed in all perfusate systems ex vivo indicating that the degradation occurs in situ. The disodium salt of ethylenediaminetetraacetic acid (EDTA) was shown to be an effective absorption enhancer of ethiofos. The enhancement of intestinal absorption by EDTA was dose-dependent resulting in a 20-fold increase in blood levels of ethiofos in the portal blood. Follow-up studies in the rhesus monkey confirm this observation. Salicylate and dimethylsulfoxide (DMSO) also resulted in absorption enhancement although to a lesser degree than that seen after EDTA treatment. Addition of several alkaline phosphatase inhibitors did not significantly improve absorption of ethiofos in the rat small intestine. Proposed mechanism(s) for intestinal absorption and absorption enhancement of ethiofos are discussed.

Adherence mechanisms of Candida albicans. (2000)

The yeast Candida albicans is an opportunistic fungal pathogen that is capable of inducing a range of superficial and systemic diseases in the immunocompromised host. Although it displays a variety of virulence factors, one--the ability to adhere to host tissue--is considered essential in the early stages of colonisation and tissue invasion. Adherence is achieved by a combination of specific (ligand-receptor interactions) and non-specific (electrostatic charge, van der Waals forces) mechanisms which allow the yeast to attach to a wide range of tissue types and inanimate surfaces. Conventional methods for treating disease cause by C. albicans rely upon the use of antifungal drugs designed to kill the yeast or arrest its growth. An alternative approach, aimed at disrupting the adherence of the yeast to host tissue in cases of superficial infection, may have potential for controlling disease, particularly in situations where the unattached fungal cell can be removed from the affected site, either by the flushing action of the oropharynx or by the production of mucus in the vagina.
Abstract 19530: Functional Assessment of Coronary Artery Disease Using Low-dose Dynamic Computed Tomography Perfusion (2015)

Introduction: Computed tomographic angiography (CTA) is, despite its limitations, a powerful modality for noninvasive assessment of coronary artery disease (CAD). Current dynamic CT perfusion (CTP) techniques aim to improve CAD assessment, but deliver high radiation doses, limiting their clinical feasibility. Therefore, we propose a low-dose, dynamic CTP technique that allows for vessel-specific, functional assessment of CAD. Methods: A coronary angioplasty balloon was advanced into the proximal left anterior descending (LAD) coronary artery of seven swine (35-45 kg) to induce several levels of stenosis at maximal hyperemia (IC adenosine, 240 μg/min). Reference fluorescence microspheres and IV contrast (370 mg/mL iodine, 25 mL, 7 mL/s) were injected and prospective, ECG-gated dynamic CTP was performed using a 320-slice CT scanner at 100 kVp and 200 mA. Twenty volume scans were acquired per stenosis level for dose comparison to current techniques, but only two volume scans, denoted as V 1 and V 5 , were used for CTP measurement. V 1 was the first volume scan after the aortic input function exceeded a triggering threshold of 180 HU, and V 5 was the fifth volume scan post aortic triggering. All CTP measurements were compared to reference microsphere perfusion measurements using linear regression. Results: The result of dynamic CTP measurement was in good agreement with reference microsphere perfusion measurement (P CTP = 0.91 P MICRO + 0.37, R 2 = 0.85), as shown in the figure. Additionally, the effective dose of the proposed technique using a two-volume scan acquisition protocol was 2.6 mSv; much lower than the ~10 mSv effective dose of current dynamic CTP techniques. Conclusions: The results indicate the potential for substantial dose reduction in dynamic CTP while maintaining measurement accuracy. By reducing the number of volume scans necessary for accurate perfusion measurement, vessel-specific functional assessment of CAD by dynamic CTP is clinically feasible.
Molecular Magnetic Resonance Imaging (2005)

Purpose: To investigate the dosimetric accuracy of the sliding window gated IMRT compared with the static treatment, using varying dose rates.Materials and methods: This study measured changes in output and diode array response with changing dose rate, verified the precision of the motion table, and measured changes in dose distribution accuracy with film and diodes at two depths with changing dose rate.During 4DCT (4 Dimensional Computed Tomography), the patient's respiratory signals and target motion were recorded and imported to the XY4D simulation table of SUN NUCLEAR Corporation to simulate the patient's respiration and tumour motion.A single field of each sliding window IMRT plan with 30º wedge and one for lung cancer were used in this study.Three irradiating conditions, static and moving target with and without gating, were applied to both plans.Results: The standard deviations of output, with the dose rates changing from 300-600 MU/min, were 0.065 cGy and 0.169 cGy for the ionisation chamber and diode, respectively.The verification of the motion table shows very good precision with 9.98 ± 0.02 cm (true value = 10.0 cm).The measurements by MapCheck show the gamma index of the planned absolute dose distribution in static and moving targets with gating, resulting in more than 96% passing for all dose rates.The absolute dose distribution measured by film for the static target was agreeable with the value of moving target with gating. Conclusion:The sliding window gated IMRT technique is able to deliver an accurate dose to a moving target with the dose rate of 300-600 MU/min that is suitable for clinical treatment.
Extracting phase distortion from laser glints on a remote target using phase space plenoptic mapping (2019)

Directed energy systems rely on the phase conjugation concept to focus laser beams remotely through turbulent environments. In application, a major problem exists where the beacon signal may be neither well defined upon generation nor free from speckle patterns in its vicinity. Such phenomena make it challenging to extract accurate phase information from the scene of a laser beacon and to direct a phase conjugated beam toward the target. In this work, we propose and demonstrate the use of a plenoptic sensor system that images the 4D phase space of multiple glints on a target. A phase retrieval algorithm is designed and applied to reveal the phase distortion from irregular glint patterns. The reconstruction results are verified through comparison with the phase retrieval from a well-defined beacon that alternates its on/off illumination in adjacent frames. As a result, we show that the multi-glint interference problem can be solved using the plenoptic sensor system, which further broadens the application scenarios for directed energy systems.

Location-Clustering Techniques For Wlan Location Determination Systems (2006)

AbstractWe present location clustering as a technique to significantly reduce the computational requirements of WLAN location determination systems. We provide two algorithms, joint clustering and incremental triangulation, and describe their trade-offs between computational cost and location determination accuracy. Both techniques reduce computational cost by more than an order of magnitude, allowing noncentralized implementation on mobile clients and enabling new context-aware applications. We present a performance comparison of the two techniques in an actual testbed implementation.Key Words: Energy efficient WLAN location determinationlocation-aware systemsradio map locations clusteringuser positioningwireless LAN Additional informationNotes on contributorsM.

A View Environment to Reuse Class Hierarchies in an Object-Oriented Database System (1991)

Many studies of interactive environments of object-oriented databases are based on extensions to declarative query languages, designed for relational databases. Such environments do not use well the characteristics of the object-oriented databases. In this paper, we introduce an environment that allows users to construct tailored class hierarchies, which represent both the users’ views and the users’ queries to the object-oriented databases. In this environment, users express their queries in the form of class hierarchies. The results of the queries are stored as classes of the tailored class hierarchies. There are three kinds of class hierarchies: original class hierarchies (databases themselves), domain class hierarchies (collections of domains), and tailored class hierarchies (user-made queries). We define the semantics and the constraints of the three kinds of class hierarchies and the basic operations to evolve them, to modify them, to cut them, to copy them, and to paste them.

Test strategies for fine pitch wafer level packaged devices (2004)

The objective of this work is to be able to test wafer level packaged devices at 5 GHz given tight mechanical constraints such as very fine pitch (of the order of 100 micron) and large pin count of thousands. Good electrical contact at the wafer level after the attachment of interconnects is needed for producing reliable electrical test results.. This paper describes the details of modeling, fabrication and the test methodology as applied to the electrical characterization of fine pitch and large pin count wafer level packaged devices.
A Lim protein involved in the progression of cytokinesis and regulation of the mitotic spindle (2003)

DdLimE regulates cell motility and cytokinesis in Dictyostelium. To specify its function, we generated knock-out mutants and analyzed mitosis by marking the mitotic apparatus with GFP-alpha-tubulin. Characteristic of DdLimE-null cells is a late reversal of cytokinesis caused by backward movement of the incipient daughter cells. This process of "retro-cytokinesis" is accompanied by a delay in disassembly of the mitotic spindle. The length of interphase microtubules is increased and their depolymerization at prophase is impaired. These data indicate that DdLimE links the cortical actin network, where it is located, to the microtubule system, whose dynamics it regulates.
Metal(II) Hexafluorophosphates(V) (M = Sr, Pb) Containing XeF2-Coordinated Metal Ions [M(XeF2)3](PF6)2, [Pb3(XeF2)11](PF6)6, and [Sr3(XeF2)10](PF6)6 (2007)

From the system MF(2)/PF(5)/XeF(2)/anhydrous hydrogen fluoride (aHF), four compounds [Sr(XeF(2))(3)](PF(6))(2), [Pb(XeF(2))(3)](PF(6))(2), [Sr(3)(XeF(2))(10)](PF(6))(6), and [Pb(3)(XeF(2))(11)](PF(6))(6) were isolated and characterized by Raman spectroscopy and X-ray single-crystal diffraction. The [M(XeF(2))(3)](PF(6))(2) (M = Sr, Pb) compounds are isostructural with the previously reported [Sr(XeF(2))(3)](AsF(6))(2). The structure of [Sr(3)(XeF(2))(10)](PF(6))(6) (space group C2/c; a = 11.778(6) Angstrom, b = 12.497(6) Angstrom, c = 34.60(2) Angstrom, beta = 95.574(4) degrees, V = 5069(4) Angstrom(3), Z = 4) contains two crystallographically independent metal centers with a coordination number of 10 and rather unusual coordination spheres in the shape of tetracapped trigonal prisms. The bridging XeF(2) molecules and one bridging PF(6)- anion, which connect the metal centers, form complicated 3D structures. The structure of [Pb(3)(XeF(2))(11)](PF(6))(6) (space group C2/m; a = 13.01(3) Angstrom, b = 11.437(4) Angstrom, c = 18.487(7) Angstrom, beta = 104.374(9) degrees, V = 2665(6) Angstrom(3), Z = 2) consists of a 3D network of the general formula {[Pb(3)(XeF(2))(10)](PF(6))(6)}n and a noncoordinated XeF(2) molecule fixed in the crystal structure only by weak electrostatic interactions. This structure also contains two crystallographically independent Pb atoms. One of them possesses a unique homoleptic environment built up by eight F atoms from eight XeF(2) molecules in the shape of a cube, whereas the second Pb atom with a coordination number of 9 adopts the shape of a tricapped trigonal prism common for lead compounds. [Pb(3)(XeF(2))(11)](PF(6))(6) and [Sr(3)(XeF(2))(10)](PF(6))(6) are formed when an excess of XeF(2) is used during the process of the crystallization of [M(XeF(2))(3)](PF(6))(2) from their aHF solutions.

Structural properties of self-organized semiconductor nanostructures (2004)

Instabilities in semiconductor heterostructure growth can be exploited for the self-organized formation of nanostructures, allowing for carrier confinement in all three spatial dimensions. Beside the description of various growth modes, the experimental characterization of structural properties, such as size and shape, chemical composition, and strain distribution is presented. The authors discuss the calculation of strain fields, which play an important role in the formation of such nanostructures and also influence their structural and optoelectronic properties. Several specific materials systems are surveyed together with important applications.

Effect of nozzle geometry on mixing in turbulent free orifice jets (2015)

Particle image velocimetry (PIV) technique was used to perform velocity measurements in the near and developing regions of orifice jets to determine the effect of nozzle geometry on the flow field. The orifice geometries studied include round, square, rectangle and ellipse (of aspect ratio 2). The Reynolds number based on equivalent diameter (d) of the nozzles was kept constant at approximately Red = 5400. The rectangular and elliptical nozzles show greater mass entrainment, higher spread rates and greater Reynolds shear stress levels when compared to the square and round nozzles.
