The Transmogrifier-2 (1997)

This paper describes the Transmogrifier-2, a second generation multi-FPGA system. The largest version of the system will comprise 16 boards that each contain two Altera 10K50 FPGAs, four I-cube interconnect chips, and up to 8 Mbytes of memory. The inter-FPGA routing architecture of the TM-2 uses a novel interconnect structure, a non-uniform partial crossbar, that provides a constant delay between any two FPGAs in the system. The TM-2 architecture is modular and scalable, meaning that various sized systems can be constructed from the same board, while maintaining routability and the constant delay feature. Other features include a system-level programmable clock that allows single-cycle access to off-chip memory, and programmable clock waveforms with resolution to 10ns. The first Transmogrifier-2 boards have been manufactured and are functional. They have recently been used successfully in some simple graphics acceleration applications.
Dendrons on insoluble supports: synthesis and applications (2007)

The range of composite materials, integrating insoluble organic or inorganic solids and fragments based on dendritic architecture, has been expanded considerably during the last decade. Though the dendritic parts of these hybrids often constitute only a minor portion of the total volume, these components can dramatically alter the properties of the support, imparting new features and functions on the materials. In most cases, organic or metalloorganic dendrons are tethered through their focal point to silica, polystyrene, or other insoluble support, and the formed hybrid materials are used as synthetic intermediates, high-loading supports for solid-phase synthesis, heterogeneous catalysts, and stationary phases in separation processes. This perspective surveys the different types of such materials, both from the synthetic and applicative points of view.
Effect of Postoperative Mechanical Axis Alignment on the Fifteen-Year Survival of Modern, Cemented Total Knee Replacements (2010)

A postoperative mechanical axis of 0° ± 3° did not improve the fifteen-year implant survival rate following these 398 modern total knee arthroplasties. We believe that describing alignment as a dichotomous variable (aligned versus malaligned) on the basis of a mechanical axis goal of 0° ± 3° is of little practical value for predicting the durability of modern total knee arthroplasty implants.

A Methodology of Modelling a Wave Power System via an Equivalent RLC Circuit (2016)

The equivalent circuit method can be an effective modelling technique for system studies of point absorbing wave energy converters (WECs). For the continuously evolving design and study of WEC systems, an instruction on how to draw the corresponding equivalent RLC circuit model is needed. It is not only vital to make sure the model is correct, but to allow the model to be easily adapted for different cases and implemented by different researchers. This paper presents a force analysis-oriented methodology based on a typical WEC unit composed of a heaving buoy and a linear generator. Three cases are studied in order to demonstrate the procedures: the generator with a retracting spring, the connection line with a rubber damper, and buoy motion in both heave and surge directions. The presented methodology serves as a guide to produce nonlinear circuit models that give a reliable description of the dynamics of real wave energy systems.

Reconstitution ratio is critical for alloreactive T cell deletion and skin graft survival in mixed bone marrow chimeras (1995)

Although allogeneic bone marrow (BM) transplantation is an effective way to induce donor-specific tolerance, its clinical application is hampered because of the risk associated with vigorous myeloablative pretransplant conditioning. One approach to overcome this problem is to establish a lower chimeric state by mild myeloablation. It is not clear, however, whether there is a threshold in the extent of chimerism that is required for tolerance induction. In this study, we establish a mixed BM chimera system to examine the correlation between the reconstitution ratio of BM chimerism, donor-reactive T cell deletion, and skin graft acceptance using I-E alpha transgenic C57BL/6 mice as the BM and skin graft donors and Ly5 congenic C57BL/6 mice as the recipients. In this system, the class II MHC molecule I-E was the transplantation Ag, and the extent of I-E-reactive T cell deletion was determined by flow cytometry using a mAb specific for the V beta 11 TCR. The degree of BM chimerism was measured by examining the expression of donor-derived Ly5.2 and host-derived Ly5.1 on peripheral blood cells. Transplantation of I-E+ transgenic donor BM cells resulted in deletion of V beta 11+CD4+ T cells in recipient's PBL, and the extent of deletion was proportional to the degree of chimerism. When mice of different degrees of chimerism were tested for skin graft survival, we found that recipient mice with > 30% chimerism could accept skin grafts from I-E+ donor mice, whereas those with < 10% chimerism showed prolonged but not permanent graft survival. These findings revealed the sequence of events for induction of tolerance. First, the degree of BM chimerism determines the number of I-E+ cells in the thymus, which then elicits negative selection of I-E-reactive T cells in a form of clonal deletion. The extent of T cell deletion ultimately determines the mode of tolerance. These data provide experimental evidence for the potential use of partial chimerism by bone marrow transplantation for the induction of donor-specific tolerance in clinical settings.

L'evenement d'integration a ete recherche en selectionnant les protoplastes sur antibiotique ou herbicide. Des plantes ont ete regenerees, et l'analyse moleculaire a pu montrer l'integration du gene de la proteine de capside dans le genome de ces plantes.
<title>Influence of serum proteins on the accumulation of aminolaevulinic acid-induced protoporphyrin IX in cells in culture</title> (1994)

Aminolaevulinic acid (ALA) induced porphyrin biosynthesis and the resulting in vitro phototoxicity have been determined in both SV40 transformed Swiss mouse 3T3 fibroblasts and PtK<sub>2</sub> epithelial cells. Both cell lines respond to the addition of exogenous ALA, producing porphyrin linearly with ALA concentrations up to 0.3 mM. Notably the only accumulating porphyrin detected by HPLC was PpIX. Although the levels of PpIX are both dependent on the time and concentration used, the final intracellular porphyrin concentration is dictated by the presence of serum. When ALA is added in medium containing 10% new born calf serum, 90 - 95% of the induced porphyrin appears in the incubation medium. In the absence of serum, the intracellular PpIX levels are maintained and only under these conditions can successful in vitro PDT be performed. Gel permeation chromatography has indicated that the afflux of PpIX is promoted by the low density and high density lipoproteins, with an unknown protein (mw &lt; 66000) contributing significantly to the effect seen. It appears that this protein is present at very low concentrations in both foetal and new born calf serum.

High-Pressure Phase Behavior of the System PCHC−CHO−CO2 for the Development of a Solvent-Free Alternative toward Polycarbonate Production (2005)

Thermodynamic phase equilibrium data relevant to the copolymerization of carbon dioxide (CO2) and cyclohexene oxide (CHO) are reported in this paper. In this system, the need for additional solvents can be prevented by using an excess of the comonomer CO2. Therefore, the solubility of poly(cylcohexene carbonate) (PCHC) in CO2 and the effects of molecular weight and CHO concentration have been experimentally determined using a high-pressure view cell. Since extremely high pressures are required to dissolve PCHC in CO2, only low-molecular-weight polymer is soluble within the experimental pressure range. Addition of CHO results in a significant decrease of the cloud-point pressures and a change of the slope of the cloud-point curve in PT-space. The perturbed-chain SAFT equation of state has been successfully used for the correlation and the prediction of the phase behavior in this range. At high temperatures the PC-SAFT model allows for a quantitative description of the phase behavior, whereas at lower temperatures PC-SAFT tends to overestimate the cloud-point pressures.
Best practice methods for determining an electrode material's performance for ultracapacitors (2010)

Ultracapacitors are rapidly being adopted for a wide range of electrical energy storage applications. While ultracapacitors are able to deliver high rates of charge and discharge, they are limited in the amount of energy stored. The capacity of ultracapacitors is largely determined by the electrode material and as a result research to improve the performance of electrode materials has dramatically increased. While test methods for packaged ultracapacitors are well developed, it is often impractical for the materials scientist to assemble full sized, packaged cells to test electrode materials. Methodology to reliably measure a material's performance for use as an ultracapacitor electrode is not well standardized with various techniques yielding widely varying results. In this manuscript, we review and validate best practice test methods that accurately predict a material's performance, yet are flexible and quick enough to accommodate a wide range of material sample types and amounts.
Detection of Explosive Vapors by Surface Acoustic Wave Sensors Containing Novel Siloxane Based Coatings (2010)

Abstract Surface acoustic wave (SAW) sensor was coated with a new chemoselective polymer to detect nitroaromatic explosives. Adsorption of the analyte influences the propagation of SAW and thus causes a shift in the resonant frequency of the SAW device. A novel azobenzene functionalized siloxane polymer was developed and applied to a surface acoustic wave (SAW) sensing device for the detection of explosive vapors such as 2,4-dinitrotoluene (DNT) and 2,4,6-trinitrotoluene (TNT). The experimental setup used for evaluating the response of this polymers-coatings is described in the paper. Experimental results indicate that the viscoelastic properties of the polymer coating is fairly insensitive to the temperature changes occurring in our experiments, which is ideal for SAW sensing device. The PDMS coating is able to detect DNT and TNT vapors.

OptiSol Corneal Storage Medium and Transmission of Treponema Pallidum (1995)

This study was conducted to provide experimental information on the probability of syphilis transmission resulting from corneal transplantation. To determine the effects of commonly employed corneal storage conditions on the survival and infectivity of Treponema pallidum, T. pallidum subsp. pallidum (Nichols) was inoculated into OptiSol storage medium or a T. pallidum survival medium at a concentration of 10(6)/ml and incubated in cornea viewing chambers for 24 h at 4 degrees C. When inoculated intradermally into rabbits (0.1 ml per site), none of the 10 sites developed lesions from suspensions incubated in OptiSol in the presence or absence of 100 microgram/ml gentamicin; T. pallidum incubated in the survival medium yielded lesions at one of 10 sites, whereas freshly extracted organisms produced lesions at all 10 sites. In another set of experiments, the infectivity of corneal tissue from rabbits inoculated intratesticularly with 2 x 10(7) T. pallidum 10 days earlier was determined. Corneas from five T. pallidum-infected rabbits were excised, extracted, and tested for infectivity either immediately after removal or after 24-h storage in OptiSol. Recipient rabbits developed lesions at five of 50 intradermal sites when the corneas were neither stored in OptiSol nor rinsed before extraction. Corneas from 10 donor rabbits that were rinsed with phosphate-buffered saline to remove blood and aqueous humor before extraction did not yield lesions at any of 200 sites in the recipient animals. The results of this study indicate that retention of T. pallidum infectivity is poor under typical corneal storage conditions and that rabbit corneal tissue contains few, if any, infectious T. pallidum organisms under the experimental conditions employed.
Control system design for the constellation acquisition phase of the LISA mission (2009)

The objective of the constellation acquisition phase for the LISA mission is to establish the three laser links between the three spacecraft of the LISA constellation so that the interferometric measurements for the science experiment can commence. The laser beam acquisition for LISA is extremely challenging given the 5 million km distance between the spacecraft, the inherent limits of the attitude sensors accuracy, the orbit determination accuracy issues and the time required to phase-lock the incoming and outgoing laser signals. This paper presents the design of the control system for the acquisition phase of the LISA constellation: the acquisition operational procedure is outlined, guidance laws are defined together with the Gyro Mode attitude control principle, which implements a Kalman filter for disturbances rejection purposes. Constellation-wide non-linear simulations demonstrate that the LISA constellation acquisition phase is feasible by means of the proposed control strategy.
Spectroscopy on polymer-fullerene composites and photovoltaic cells (2001)

We investigate the electrical transport properties of ITO/conjugated polymer-fullerene/Al photovoltaic cells and the role of defect states with the help of admittance spectroscopy and magnetic resonance technique. In the temperature range 293-40K, a characteristic step in the admittance spectrum can be observed originating from the electrically active acceptor level. The activation energy determined from an Arrhenius plot is 34meV. The diode capacitance as a function of the reverse bias is different from the Schottky diode behaviour. We found a bias independent capacitance under reverse bias. This indicates that the devices are either fully depleted, or the space charge region exceeds the device thickness. An efficient generation of charge carriers and their fate in these systems have been studied by electron spin resonance (ESR). We can clearly follow the formation of photo-generated electron-hole pairs under illumination of the device absorber. Using high-frequency (95 GHz) light induced ESR it was possible to separate these two contributions to the spectrum on the basis of their g-parameters, and to resolve the g-anisotropy of the radicals. The P + -polaron possesses an axial symmetry whereas for C 60 + a lower, rhombic symmetry was observed. Important for the cell performance is that photo-generated electron-hole pairs remain in the composites even after the photo-excitation has been switched off, implying the presence of defect-induced trap states.
The Nanopore-FET as a High-Throughput Barcode Molecule Reader for Single-Molecule Omics and Read-out of DNA Digital Data Storage (2022)

Nanopore technology has augmented DNA sequencing, and nascent nanopore-based technology breakthroughs may lead to major steps forward in large-scale molecular analysis (omics) and DNA digital data storage. A major weakness of current nanopore technologies is the requisite recording of pico-to nanoampere ionic currents. Such low currents limit recording bandwidth in large integrated arrays and impose a limit on how quickly a detectable molecule can cross, or translocate the pore. The Nanopore Field Effect Transistor (NPFET) is a nanopore surrounded by a nanoscale field-effect transistor. The field-effect transistor senses single molecules translocating through the pore relying on much larger microampere currents. The NPFET potentially offers higher bandwidths in large integrated arrays and the breaking of the nanopore translocation speed limit. Moreover, because individual electrolyte contacts are not required for NPFETs they are more easily integrated into large arrays than nanopores. NPFETs may lead to major strides in high throughput reading of molecularly encoded information. We will introduce and elaborate on nanopore FET technology research for omics and DNA data storage and we will propose a scaling roadmap that aims to incrementally boost NPFET molecular read throughput.
