Chemical surface deposition of ultra-thin cadmium sulfide films for high performance and high cadmium utilization (2003)

Chemical surface deposition (CSD) of CdS films is described. In this process, heat from the substrate provides the energy needed for reaction at the surface, resulting in heterogeneous deposition. Deposition from an aqueous solution containing cadmium species, thiourea and ammonia yields dense conformal CdS films, with > 90% utilization of Cd species. The CdS films exhibit negligible occurrence of pinholes and particulates, making CSD films suitable for inclusion in substrate or superstrate solar cell designs. The optical and structural properties of CSD CdS films on polycrystalline substrates are reported. Device results are presented for CdTe and Cu(InGa)Se/sub 2/ solar cells using CSD CdS window layers.
‘LDL-C’ = LDL-C + Lp(a)-C (2015)

As the new era of ultralow LDL-C levels ensues, it is imperative to understand the contribution of Lp(a)-C to measured LDL-C and the consequences of achieving ultralow or potentially absent LDL-C in the setting of elevated Lp(a) levels and possibly free apo(a). We review this concept and suggest avenues of research, including analyses of existing datasets in current clinical trials and new research studies, to understand its pathophysiological and clinical significance.
A fully asynchronous low-power error corrector for the DCC player (1994)

A fully asynchronous implementation of a complete DCC error corrector is presented that consumes 10 mW at 5 V, only a fifth of its synchronous counterpart, This is achieved by eliminating clocks, and exploiting the additional freedom in architecture provided by the absence of a clock. The corrector has been integrated in an experimental player and is both functionally and audibly correct. Handshake circuits are proposed as an architecture that enables structured design of asynchronous circuits through a consistent application of handshake signaling at all design levels. Handshake circuits are compiled fully automatically from high-level descriptions, and are implemented quasi delay insensitively using 4-phase handshake signaling and double-rail data encoding. The resulting circuits are self-initializable and testable.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Simultaneous saccharification and fermentation of steam‐pretreated bagasse using <i>Saccharomyces cerevisiae</i> TMB3400 and <i>Pichia stipitis</i> CBS6054 (2007)

Sugarcane bagasse--a residue from sugar and ethanol production from sugar cane--is a potential raw material for lignocellulosic ethanol production. This material is high in xylan content. A prerequisite for bioethanol production from bagasse is therefore that xylose is efficiently fermented to ethanol. In the current study, ethanolic fermentation of steam-pretreated sugarcane bagasse was assessed in a simultaneous saccharification and fermentation (SSF) set-up using either Saccharomyces cerevisiae TMB3400, a recombinant xylose utilizing yeast strain, or Pichia stipitis CBS6054, a naturally xylose utilizing yeast strain. Commercial cellulolytic enzymes were used and the content of water insoluble solids (WIS) was 5% or 7.5%. S. cerevisiae TMB3400 consumed all glucose and large fraction of the xylose in SSF. Almost complete xylose conversion could be achieved at 5% WIS and 32 degrees C. Fermentation did not occur with P. stipitis CBS6054 at pH 5.0. However, at pH 6.0, complete glucose conversion and high xylose conversion (>70%) was obtained. Microaeration was required for P. stipitis CBS6054. This was not necessary for S. cerevisiae TMB3400.
Interactive Image Restoration Using Inpainting and Denoising (2011)

Digital in painting is the technique of filling in the missing regions of an image using information from the surrounding area in a visually indistinguishable way. In this paper, we try to improve the Exemplar based method by manipulating the values of various parameters like patch size, shape and size of the mask. We present an analysis of the impact of various geometric parameters on the quality of in painted images. Image denoising refers to the removal of unwanted noise from the images. In most cases, the images which need to be in painted are noisy, which makes it necessary to eliminate noise and fill in the missing regions from neighboring pixels. Therefore, filling in of missing regions and removal of noise are the two very important topics in image processing. This paper also addresses the issue of performing both in painting and denoising simultaneously using two different approaches: pipelined approach and interleaved approach. The effectiveness of these approaches is demonstrated with a number of results on various images.
Application of electronic sector scanning techniques to height-finding radar systems (1963)

This paper considers the application of electronic scanning in the vertical plane to provide additional height information for surveillance radar systems. It is shown that, if the electronic scanning rate is made equal to the reciprocal of the pulse duration, this can result in the production of a 3-dimensional radar with a high data rate and several useful facilities for air-traffic surveillance. These include: slant-range correction, reduction of zenithal gap, individual aircraft height extraction and height-layering facilities.Consideration is also given to a technique of multiplicative signal processing which can provide increased height accuracy for very little additional equipment.A proposed scheme for such a radar is put forward using techniques which have already received some experimental study, and the scheme is compared briefly with stacked-beam radar systems. The proposed radar appears to possess most of the facilities of the stacked-beam radars, together with improved height-layering facilities and a high reliability.
Reactive control for mobile manipulation (2002)

Research for executing large-scale motions of mobile manipulators is described. Mobile manipulators are mobile bases with an attached arm which function in an integrated manner. Motivation is given for moving the arm while the base is moving. This paper applies reactive control concepts to achieve this type of motion. Tools for modeling integrated arm-vehicle kinematics and dynamics are discussed. Kinematics- and dynamics-based concepts are combined with reactive control approaches in order to move toward a practical level of complexity and performance. Simulation results are presented.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Production of palm frond based wood plastic composite by using twin screw extruder (2018)

Wood plastic composite (WPC) is the blending product from wood as filler and polymer thermoplastic as matric. Palm frond waste is a material with selulose about 68%, so it has potential to be developed as raw material for WPC. The purpose of this research was to learn how to produce WPC based on palm frond use twin screw extruder. It used popropilen as matric. As for aditif, it used Maleated Polypropilene (MAPP) as compatibilizer and paraffin as plasticizer. The size of palm frond is 40 – 80 mesh. WPC is made from blending polipropylene, palm frond, MAPP and paraffin with dry mixing method in room temperature. Then, PP, Palm frond and additive from dry mixing is fed into twin screw extruder at 190°C and 60 rpm. It use palm frond/polypropylene 60/40, MAPP 5% w/w and paraffin 2% w/w. From the result, it shown that WPC based on palm frond met the standards forcommercial WPC. It has tensile strength up to 19.2 MPa, bending strength 43.6 MPa and water adsorption 0,32% w/w. So, WPC based on palm frond has prospective to be developed for commercial WPC.
GeminiII: a second generation layout validation program (2003)

Gemini is a program that is widely used to compare circuit layout against a specification. Extensions to Gemini that make it faster, enable it to isolate errors better, and extend its domain of application, are described. These improvements have been achieved by changes to the labeling algorithm, extensions to the local matching algorithm, better handling of symmetrical circuits, and the accommodation of series-connected transistors. GeminiII's algorithm is separated into global labeling and local matching phases. GeminiII dynamically switches between the two, depending on the amount of local structure contained in the circuit, taking advantage of the speed of the local matching algorithm when possible and relying on the power of the more general algorithm when the simple algorithm fails.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Proton Pump Inhibitor Therapy and Osteoporosis (2008)

Osteoporotic fractures, particularly hip fractures, can have a devastating impact on the well-being of the elderly population. Recently, two population-based observational studies reported a highly important association between the use of potent acid suppressive therapy and an increased risk of hip fractures. The mechanisms underlying such an association are not clear. However, a careful review of the existing evidence seems to suggest that the main physiologic consequences of proton pump inhibitor therapy may each have a theoretical influence on bone metabolism. Specifically, inhibition of the osteoclastic proton pumps may reduce bone resorption, while profound acid suppression could potentially hamper intestinal calcium absorption, and secondary hypergastrinemia may enhance bone resorption through the induction of parathyroid gland hyperplasia. However, the existing data are clearly too limited for us to draw any definitive conclusions, and more studies are urgently needed to delineate the physiologic relevance of these theoretical mechanistic links, individually and collectively.
Activation of resting human B cells by helper T-cell clone supernatant: characterization of a human B-cell-activating factor. (1987)

The effects of helper T-cell clone supernatants on resting human B cells were investigated. Four different helper T-cell clones (two T4+ and two T8+) were stimulated by anti-T3 monoclonal antibodies on Sepharose beads or anti-T11(2) plus anti-T11(3) monoclonal antibodies. The supernatants from these activated clones induced the proliferation of highly purified resting B lymphocytes from the peripheral blood. The B cells exhibited a cell size and a surface-antigen pattern (4F2 antigen and transferrin receptor) of phase G0 B cells, and they were functionally resting. In response to T-cell supernatants a large fraction of the B cells enlarged and expressed 4F2 antigens and transferrin receptors. In gel filtration, the corresponding activity migrated with an apparent Mr of 12,000-15,000. Our findings strongly support the existence of a human B-cell-activating factor acting on resting B cells and causing them to enter phase G1 of the cell cycle.
Thermally Generated Flavors (1993)

This symposium is very timely and important since extrusion and microwave food processing are rapidly being commercialized and applied by the food and consumer products' industries. These processes give food manufacturers the opportunity to process foods more efficiently and develop new innovative food products for their worldwide consumers. A common problem in both of these processes is that the heat induced Maillard aroma development which occurs during extrusion or microwave cooking is less acceptable than the aroma developed during conventional cooking. Nevertheless, rapid industrial and consumer acceptance of extrusion and microwave cooking will require both understanding and application of the fundamental chemistry associated with Maillard browning to overcome the aroma deficiency. Other shortcomings associated with microwave and extrusion processing will be minimized as the technologies further develop, but the fundamental aroma deficiency will remain, and the solution is a challenge to food chemists. The intention of this symposium is to focus on this important and relevant problem.
Fiberoptic probe for measuring high frequency temperature fluctuations in combustion gases (1984)

A new fiberoptic probe for measuring high frequency gas-temperature fluctuations is described. The fiberoptic probe is an optical pyrometer in which the thermal radiation is transmitted through an optical fiber. The key element in the device is a high temperature optical fiber made of single-crystal alumina (sapphire), which remains transparent and nonemitting in the optical and near infrared at temperatures up to its melting point, 2345 K. On one end of the fiber a thin film of platinum or other high temperature alloy serves as a thermal radiator. The other end of the high temperature fiber is connected to a photodetector through a conventional fused silica fiber. In operation, thermal radiation from the metallic thin film is collected by the high-temperature fiber and transmitted through the conventional optical fiber to a detector assembly. The radiation is then transmitted through a band pass filter, and the intensity is measured using a photodetector. The system is calibrated to account for the emissivity of the thin-film tip, the responsivity of the detector and the gain of the amplifier. The frequency response of the fiberoptic probe is inherently superior to that of fine-wire thermocouples, because the output of the fiberoptic device depends only onmore » the surface temperature of the probe. The output of a thermocouple depends on the internal temperature of the wire. As a result, the transfer function that relates gas temperature to probe temperature decreases 3 db per octave at high frequency rather than 6 db per octave characteristic of thermocouples. Experimental results demonstrate the capability of measuring temperature fluctuations up to 14 KHz in combustor exhaust gases.« less
Reconfigurable computing: what, why, and implications for design automation (2003)

Reconfigurable computing is emerging as an important new organizational structure for implementing computations. It combines the post-fabrication programmability of processors with the spatial computational style most commonly employed in hardware designs. The result changes traditional "hardware" and "software" boundaries, providing an opportunity for greater computational capacity and density within a programmable media. Reconfigurable computing must leverage traditional CAD technology for building spatial designs. Beyond that, however, reprogrammability introduces new challenges and opportunities for automation, including binding-time and specialization optimizations, regularity extraction and exploitation, and temporal partitioning and scheduling.
Accurate localization of low-level radioactive source under noise and measurement errors (2008)

The localization of a radioactive source can be solved in closed-form using 4 ideal sensors and the Apollonius circle in a noise- and error-free environment. When measurement errors and noise such as background radiation are considered, a larger number of sensors is needed to produce accurate results, particularly for extremely low source intensities. In this paper, we present an efficient fusion algorithm that can exploit measurements from n sensors to improve the localization accuracy, and show how the accuracy scales with n. We report testbed results for a 0.911 μCi source to illustrate the effectiveness of our algorithm, in particular performance comparisons with state-of-the-art fusion algorithms based on Mean of Estimates (MoE) and Maximum Likelihood Estimation (MLE). We show that ITP is more accurate than MoE, whereas the choice between ITP and MLE is generally a tradeoff between accuracy and run time efficiency. Higher-intensity radioactive sources are not safe for actual experiments. In this case, we present simulation results based on a validated simulation model. We show that a low-intensity 400 μCi source, similar to the radioactivity of a concealed dirty bomb, can be localized to within 32.5 m using a sensor density of about 1 per 1100 m2 in a surveillance area.
Pressure-Time Product during Continuous Positive Airway Pressure, Pressure Support Ventilation, and T-Piece during Weaning from Mechanical Ventilation (1991)

The objective of this study was to compare the effects of continuous positive airway pressure (CPAP), pressure support ventilation (PS), and T-piece on the pressure-time product (PTP) during weaning from mechanical ventilation. The PTP is an estimate of the metabolic work or oxygen consumption of the respiratory muscles. We studied 10 intubated patients recovering from acute respiratory failure of various etiologies. A modified continuous flow (flow-by) CPAP of 0 and 5 cm H2O (CPAP-0 and CPAP-5, respectively), PS of 5 cm H2O (PS-5), and T-piece were applied in random order for 30 min each. In the last 5 min of the 30-min periods, we measured the esophageal pressure and transdiaphragmatic pressure-time products--PTP(es) and PTP(di), cm H2O.s/min, respectively-multiplied by respiratory frequency. Breathing pattern, total lung resistance (RL), quasi-static lung compliance (CL), intrinsic positive end-expiratory pressure (PEEPi), end-expiratory transpulmonary pressure (Ptpexp), arterial blood gases, blood pressure, and heart rate were also measured. In comparison to T-piece, CPAP-5 decreased PTP(es) 40% (p less than 0.01) and PTP(di) 43% (p less than 0.02), whereas PS-5 decreased PTP(es) 34% (p less than 0.01) and PTP(di) 38% (p less than 0.05). The decrease in PTP(es) with CPAP-5 was associated with a significant reduction in RL, and to a less extent in PEEPi relative to airway pressure. The contribution of the decrease in PEEPi to the reduction in PTP(es) amounted to 36%. With PS-5, respiratory system mechanics and PEEPi were not significantly different compared with T-piece. With CPAP-0, PTP tended to be lower than with T-piece.(ABSTRACT TRUNCATED AT 250 WORDS)
Design of Microdisk-Shaped Ge on Si Photodetector with Recess Structure for Refractive-Index Sensing (2019)

In this paper, we introduce a disk-shaped Ge-on-Si photodetector for refractive-index difference sensing at an operating wavelength of 1550 nm. For the implementation of a small-scale sensor, a Ge layer was formed on top of a Si layer to increase the absorption coefficient at the expense of the light-detection area. Additionally, the sensor had a ring waveguide structure along the edge of the disk formed by a recess into the inner part of the disk. This increased the interaction between the dominant optical mode traveling along the edge waveguide and the refractive index of the cladding material to be sensed, and conclusively increased detection sensitivity. The simulation results show that the proposed sensor exhibited a detection sensitivity of >50 nm/RIU (Refractive Index Unit), a quality factor of approximately 3000, and a minimum detectable refractive index change of 0.95 × 10<sup>-2</sup> RIU with a small disk radius of 3 μm. This corresponds to 1.67 times the sensitivity without a recess (>30 nm/RIU).

DENSITY-INDEPENDENT MOISTURE DETERMINATION IN WHEAT BY MICROWAVE MEASUREMENT (1991)

ABSTRACT Moisture content of soft red winter wheat, Triticum aestivum L., has been expressed as a function of microwave attenuation and phase shift, measured at 9.0 GHz, independent of bulk density. The grain was held in 10.2>cm (4-in.) ID plastic tubing between two horn antennas of the measurement system. The calibration equation was veriHed with wheat of different variety and origin from the next year's crop. The average bias for the moisture content range from 10.7 to 20.4% was <0.10% and the standard error of performance was 0.26% moisture content
