Regenerative satellite mesh system for realtime multi-party multimedia traffic (2009)

Regenerative satellites with on-board packet processing can provide full-mesh, single-hop connectivity between two or among many terminals without requiring a terrestrial Hub for traffic routing and control. By implementing resource allocation and packet replication in the payload, these satellites can extend the single-hop benefits to a multi-site, real-time collaborative environment. This paper summarizes the key features of the ETSI and TIA Regenerative Satellite Mesh A (RSM-A) standards and enumerates the capabilities of a pioneering implementation, the Hughes SPACEWAY® 3 satellite system, which was launched into commercial service over North America in April 2008. Capabilities such as spot beam forming, dynamic satellite communication hardware to beam mapping, and adaptive resource control enable a responsive transport system for inelastic packet streams associated with high data-rate video and audio traffic for real-time interactions. It also describes an IP multicasting architecture over RSM-A, aligned with H.323 and SIP standards, for managing real-time, point-to-point and multiparty video conferencing applications. (9 pages)
clMAGMA: High Performance Dense Linear Algebra with OpenCL (2013)

This paper presents the design and implementation of several fundamental dense linear algebra (DLA) algorithms in OpenCL. In particular, these are linear system solvers and eigenvalue problem solvers. Further, we give an overview of the clMAGMA library, an open source, high performance OpenCL library that incorporates the developments presented, and in general provides to heterogeneous architectures the DLA functionality of the popular LAPACK library. The LAPACK-compliance and use of OpenCL simplify the use of clMAGMA in applications, while providing them with portably performant DLA. High performance is obtained through use of the high-performance OpenCL BLAS, hardware and OpenCL-specific tuning, and a hybridization methodology where we split the algorithm into computational tasks of various granularities. Execution of those tasks is properly scheduled over the heterogeneous hardware components by minimizing data movements and mapping algorithmic requirements to the architectural strengths of the various heterogeneous hardware components.

Logic model optimization for LSSD structures (2003)

A method that optimizes the logical description of an LSSD (level-sensitive scan design) structure is described. The logic model thus created results in improved efficiency of test generation, fault simulation, and failure diagnosis. Extensive testing with this system has resulted in logic-gate-count reduction up to 40%, reduction in simulation CPU time by a factor of 2, and improvement in efficiency and effectiveness in the testing environment. Significant model gate count is achieved with only a minor increase in the CPU time.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>

Multimode metal-insulator-metal waveguides: Analysis and experimental characterization (2012)

The analysis and experimental characterization of the propagation constants and attenuation coefficients of surface plasmon (SP) modes in planar multimode metal-insulator-metal (MIM) waveguides are presented. The experimental characterization is based on determining the width of the reflection angular spectrum in the attenuated total reflection (ATR) configuration. Due to its transverse character, the ATR configuration provides a more straightforward and simpler way to determine the propagation constants and attenuation coefficients of plasmonic modes in MIM structures, compared to using tapered end-couplers with multiple waveguide samples or near-field scanning optical microscopy (NSOM). In this paper, the propagation constants and attenuation coefficients of multimode MIM structures are investigated, and MIM waveguide structures with 730 and 1460 nm ${\mathrm{SiO}}_{2}$ cores and Au claddings are fabricated and experimentally characterized. The measurement results indicate that the absorption of Au is responsible for the high attenuation in MIM plasmonic modes, while scattering loss is another source of attenuation for higher-order modes (smaller zigzag angles). To the best of the authors' knowledge, the present work represents the first time the attenuation coefficient and propagation constant of each mode in a multimode MIM waveguide have been individually measured.
Plasmonics: Near‐Field Enhanced Plasmonic‐Magnetic Bifunctional Nanotubes for Single Cell Bioanalysis (Adv. Funct. Mater. 35/2013) (2013)

Unique near-field enhanced plasmonic-magnetic bifunctional nanotubes are fabricated by D. L. Fan and co-workers. Their plasmonic properties are investigated on page 4332 through both experimentation and theoretical modeling. By leveraging the bifunctionality, a nanotube can be precisely transported to a single living Chinese hamster ovary cell amidst many and reveal its membrane chemistry (lipid and protein) with SERS spectroscopy.
Improved multilevel successive elimination algorithm using efficient decision conditions (2003)

The computational process of the sum of the absolute difference (SAD) and the multilevel successive elimination algorithm (MSEA) are theoretically analyzed, and a new improved MSEA is proposed. The proposed algorithm reduces the computations required for judging invalid candidate blocks. The simulation results show that the proposed algorithm achieves a computational time savings of about 30 to 40% without additional hardware, compared to the MSEA.

The Discotic Phase of Uro-Porphyrin I Octa-N-Dodecyl Estei (1980)

Abstract A number of materials which exhibit the relatively new discotic phase have recently been discovered. All of the materials known which show this type of phase have molecular structures that are flat and hexagonal in shape. In this current work, we have shown that a porphyrin compound, uro-porphyrin I octa-n-dodecyl ester, which has a flat, octagonally shaped molecular structure can also exhibit a discotic phase. This is the first report of the discotic liquid crystal phase being exhibited by porphyrin compounds.

Microwave-Assisted Fabrication of High Energy Density Binary Metal Sulfides for Enhanced Performance in Battery Applications (2023)

Nanomaterials have found use in a number of relevant energy applications. In particular, nanoscale motifs of binary metal sulfides can function as conversion materials, similar to that of analogous metal oxides, nitrides, or phosphides, and are characterized by their high theoretical capacity and correspondingly low cost. This review focuses on structure-composition-property relationships of specific relevance to battery applications, emanating from systematic attempts to either (1) vary and alter the dimension of nanoscale architectures or (2) introduce conductive carbon-based entities, such as carbon nanotubes and graphene-derived species. In this study, we will primarily concern ourselves with probing metal sulfide nanostructures generated by a microwave-mediated synthetic approach, which we have explored extensively in recent years. This particular fabrication protocol represents a relatively facile, flexible, and effective means with which to simultaneously control both chemical composition and physical morphology within these systems to tailor them for energy storage applications.
High-throughput, high-spatial-frequency measurement of critical dimension variations using memory circuits as electrical test structures (1999)

Critical dimension (CD) errors are traditionally specified and characterized without reference to their spatial frequency spectra. However, a given amplitude of CD variation can have very different consequences depending on its spectrum. CD errors whose variation is over a few micrometers can be much more serious than those of the same magnitude that extend over several chips. Existing CD metrology tools, such as scanning electron microscopy or electrical resistance measurements, are seldom used to characterize these short-range CD variations, particularly those with spatial wavelengths below 100 μm, because of the large amount of data required and the difficulty of collecting data in such a dense grid. We report a new method of measuring CD variations using static random-access memory (SRAM) circuits in which direct measurements of bit-line currents reveal the individual transistor gate length variations within each memory cell. With the compactness and regularity of the SRAM layout we can measure CD variations with spatial periodicities down to 6 μm. By repeatedly measuring each cell in a memory chip and recording the corresponding currents we can achieve sufficient data to minimize noise, and through two-dimensional bandpass filtering 0.2 nm CD variations can be detected. Two designs of 4 Mbit SRAMs fabricated using 250 nm design rules were studied. The resulting CD variations yielded spectra that were dominated by peaks whose origins included uncorrected electron beam and optical proximity effects. Pattern-independent variations ascribable to the reticle generator itself appeared to contribute only a small fraction of the total error observed.

Functional anatomy of the anterior cruciate ligament. Fibre bundle actions related to ligament replacements and injuries (1991)

This work studied the fibre bundle anatomy of the anterior cruciate ligament. Three functional bundles--anteromedial, intermediate, and posterolateral--were identified in cadaver knees. Their contributions to resisting anterior subluxation in flexion and extension were found by repeated tests after sequential bundle transection. Changes of length in flexion and extension and in tibial rotation were measured. None of the fibres were isometric. The posterolateral bundle was stretched in extension and the anteromedial in flexion, which correlated with increased contributions to knee stability and the likelihood of partial ruptures in these positions. Tibial rotation had no significant effect. The fibre length changes suggested that the 'isometric point' aimed at by some ligament replacements lay anterior and superior to the femoral origin of the intermediate fibre bundle and towards the roof of the intercondylar notch.
Direct Detection of Indirect Transmission of Streptobacillus moniliformis Rat Bite Fever Infection (2014)

We describe the evaluation of culture-negative synovial fluid from a 3-year-old boy by PCR and electrospray ionization followed by mass spectrometry (PCR/ESI-MS). Our patient developed a diffuse rash and fever with systemic signs and symptoms of sepsis, but four sets of blood cultures obtained prior to initiation of antibiotics were negative. After 1 week of illness, he developed right-knee swelling. Analysis of synovial fluid was consistent with infection, but cultures of specimens obtained following initiation of antimicrobial treatment were negative for growth. PCR/ESI-MS detected Streptobacillus moniliformis in the synovial fluid sample. Our patient completed an appropriate course of antibiotic treatment and remained completely asymptomatic in follow-up evaluation. This unique case suggests that PCR/ESI-MS may be a useful diagnostic tool for direct detection of unusual or unexpected pathogens directly from clinical specimens, particularly when samples have been obtained from patients following initiation of antibiotic therapy.

Nodal Signaling as a Developmental Therapeutics Target in Oncology (2017)

The tumor microenvironment is a vital feature of oncogenesis and tumor progression. There are several parallels between cancer cells and early developmental stem cells, including their plasticity and signaling mechanisms. In early fetal development, Nodal is expressed for endodermal and mesodermal differentiation. This expression has been shown reemerge in the setting of epithelial cancers, such as breast and melanoma. High Nodal expression correlates to an aggressive tumor grade in these malignancies. Nodal signal begins with its interaction with its coreceptor, Cripto-1, leading to activation of Smad2/Smad3 and ultimately downstream transcription and translation. Lefty is the natural inhibitor of Nodal and controls Nodal signaling during fetal development. However, cancer cells lack the presence of Lefty, thus leading to uncontrolled tumor growth. Given this understanding, inhibition of the Nodal pathway offers a new novel therapeutic target in oncology. <i>Mol Cancer Ther; 16(5); 787-92. ©2017 AACR</i>.
Investigation of Superparamagnetic Iron Oxide Nanoparticles for MRVisualization of Surgical Implants (2012)

For the development of a surgical mesh implant that is visible in magnetic resonance imaging (MRI), superparamagnetic iron oxides (SPIOs) are integrated into the material of the mesh. In order to get a high quality mesh regarding both mechanical and imaging properties, a narrow size distribution and homogenous spatial distribution, as well as a strong magnetization of SPIOs within the filament of the mesh are required. In this work, six different samples of SPIOs composed of a magnetite core are synthesized with and without stabilizing dodecanoic acid and analyzed using a superconducting quantum interference device (SQUID), transmission electron microscope (TEM) and a magnetic force microscope (MFM) to determine the properties that are beneficial for the assembly and imaging of the implant. These analyses show the feasibility of visualization of surgical implants with incorporated SPIOs and the influence of the agglomeration of SPIOs on their magnetization and on a homogenous spatial distribution within the polymer of the mesh.
Activation-energy asymptotic theory of autoignition of condensed hydrocarbon fuels in non-premixed flows with comparison to experiment (2008)

An activation-energy asymptotic theory is developed that predicts autoignition of condensed hydrocarbon fuels in non-premixed flows. Steady, laminar, stagnation-point flow of an oxidizer stream, toward the vaporizing surface of a liquid fuel is considered. The analysis is restricted to the case where the temperature of the oxidizer stream, T 2, is greater than the normal boiling point of the liquid fuel. The gas-phase chemical reaction is described by a one-step overall process. The chemical-kinetic rate parameters are the activation temperature, T a, and the frequency factor, B. A Zel'dovich number, β, is constructed that is proportional to the ratio T a/T 2. The analysis is performed in the asymptotic limit of large values of β. It predicts the value of the Damköhler number, at autoignition. The Damköhler number is defined as the ratio of a characteristic flow time to a characteristic chemical reaction time. The flow time is the reciprocal of the strain-rate, and the chemical time depends on the chemical-kinetic rate parameters. To illustrate the application of the results of the analysis, experiments are conducted in the counterflow configuration. Fuels tested are n-heptane, n-octane, n-decane, n-dodecane, n-hexadecane, iso-octane, cyclohexane, methylcyclohexane, o-xylene, JP-10, JP-8, and diesel. The temperature of the oxidizer stream at autoignition is measured for various values of the strain-rate. The strain-rate, and the value of the Damköhler number at autoignition, obtained from the analysis, are used to obtain the chemical-kinetic rate parameters, for the fuels tested here. Critical conditions of extinction of flames burning these liquid fuels are also measured. A key finding of this work is that for the straight-chain alkanes tested here, at a given value of the strain-rate, n-heptane is the most difficult to ignite, followed by n-octane, n-decane, n-dodecane, and n-hexadecane. The order is reversed for extinction; here it is found that flames burning n-heptane and n-octane are the most difficult to extinguish followed by n-decane, n-dodecane, and n-hexadecane.
A unified method for multi-body systems subject to stick-slip friction and intermittent contact (2008)

Simulations of objects whose interaction change due to intermittent contact, collision, sticking or slipping traditionally employ mathematical models of the system in each topology. Usually these simulations rely on a tedious process of deriving separate dynamical equations for each topology and sophisticated switching logic to select the appropriate model. We introduce a unified method which requires deriving only a single set of equations and simple switching.
Peroneal and Tibial Intraneural Ganglion Cysts in the Knee Region (2010)

Understanding the joint-related basis of intraneural cysts leads to simple targeted surgery that addresses the joint, its articular branch, and the cyst. The success of the shared surgical strategy for both peroneal and tibial intraneural ganglia confirms the principles of the unifying articular theory.
Extended operation and control of biomass overgrowth in biofilters designed for VOC removal (1997)

Biofiltration systems have been applied in several industries for treatment of volatile organic compounds (VOCs); however, the systems are poorly understood and are generally implemented as black boxes. Common operational problems associated with biofilters include fouling, deactivation, and overgrowth, all of which make biofilters ineffective for continuous long-term use. The objective of this investigation was to develop generic methods for long-term stable operation, in particular by using selective limitation of supplemental nutrients while maintaining high activity and the ability to regenerate biofilter activity. Sustained degradation rates of approximately 50 g/h/m{sup 3} for isobutane and n-pentane in air (5,000 ppm) were maintained in a trickle bed bioreactor for over 12 months using a nutrient-limited liquid recycle stream. After 5 to 6 months of operation, rates quickly declined to less than 10 g/h/m{sup 3}, presumably due to extended supplemental nutrient depletion. At this time, the limiting nutrient was reintroduced into the liquid stream and previous removal rates were restored in less than two weeks. Furthermore, biological and transport fundamentals (kinetics and mass transfer) were successfully incorporated into a steady state mathematical model in order to successfully predict operating parameters and thus enable better design. Advances in these areas are particularly important formore » implementation and extended activity of biofilters in industrial settings and are directly relevant for high priority contaminants.« less
Co-phasing full-duplex relay link with non-ideal feedback information (2008)

We study a wireless full-duplex amplify-and-forward relay link where a destination receives superposition of relayed and direct signals. We propose a new relay protocol that performs co-phasing of the two paths. We analyze the performance of the relay link by calculating closed-form expressions for the average end-to-end signal-to-noise ratio assuming flat Nakagami-m fading channels and by simulating the outage capacity. In the analysis, the phase feedback information is considered non-ideal due to N <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">ph</sub> bit quantization and bit error probability ¿. We show that full-duplex relaying can offer performance improvement over both direct transmission and half-duplex relaying even with few feedback bits and with a feedback channel of relatively low quality.
Reflectarray with EBG elements for improved radiation characteristics (2013)

A reflectarray composed of elements with electromagnetic bandgap (EBG) characteristics to improve radiation performances is proposed. The EBG elements are composed of patches and multiple via‐holes to provide required reflection phase and bandgap characteristics at target frequency of 10 GHz. Compared with a normal patch reflectarray without EBG elements, the gain is improved by 1.4 dB, and the SLLs are suppressed by 1.5 dB ( E ‐plane) and 5.3 dB ( H ‐plane), respectively.
