A fully integrated CMOS receiver front-end for optic Gigabit Ethernet (2002)

A fully integrated fiber-optic receiver chip in a CMOS technology is presented. The design was done in a low-cost mixed-signal analog pure CMOS technology with 0.35-/spl mu/m gate length. It incorporates every building block needed for standard fiber-optic receiver application, e.g., transimpedance amplifier, postamplifier, signal detect, and several control circuits. The chip works without any external components, such as capacitors usually needed to ensure the broadband operation down to several tens of kilohertz. Three designs were processed for typical data applications between 155 Mb/s and 1.25 Gb/s. The difference in the designs can be created by changing only one metal mask and programming some bandwidth and noise-relevant components on the chip. The results in sensitivity, dynamic range, and other behaviors are fully compliant with the relevant standards, such as SONET or IEEE 802.3 (Gigabit Ethernet) and future IEEE 1394 plastic optical fiber (POF) communication.
Vincristine-induced self-association of calf brain tubulin (1985)

The vincristine-induced self-association of tubulin has been examined in a sedimentation velocity study as a function of free drug concentration in PG buffer (0.01 M NaPi and 10(-4) M GTP, pH 7.0) at 20 degrees C. Analysis of the weight-average sedimentation coefficient (S20,w) as a function of protein concentration showed a good fit with the model of an indefinite, isodesmic self-association mechanism. Analysis of the apparent association constants in terms of the Wyman linkage relations showed a good fit to mediation of the self-association by the binding of one ligand molecule. The intrinsic association constant for dimerization of the vincristine-liganded tubulin was found to be 3.8 X 10(5) M-1, and the intrinsic equilibrium constant for the binding of the self-association-linked vincristine molecule had a value of 3.5 X 10(4) M-1, consistent with that measured by fluorescence in our laboratory [Prakash, V., & Timasheff, S. N. (1983) J. Biol. Chem. 258, 1689-1697]. Both reactions are stronger in the presence of vincristine than of vinblastine, reflecting the oxidation of a -CH3 group to -CHO when going from the latter drug to the former one.
Quantitation in Analysis of Polymers by Multiple Detector SEC (1999)

It is shown, that SEC with dual detection is a powerful tool in the analysis of polymers and also of oligomers. For the latter, one has to take into account the molar mass dependence of response factors, if just one detecto is used. Alternatively, dual detection can be applied also in this case with advantage. Besides the molar mass dependence of response factors, another source of error is the SEC calibration, which may be considerably different not only for different homopolymers, but also for polymer homologous series with the same repeating unit, but different end groups.
Turbostratic stacked graphene-based high-responsivity mid-wavelength infrared detector using an enhanced photogating effect (2022)

We employ turbostratic stacked chemical vapor deposition (CVD) graphene for a mid-wavelength infrared (MWIR) photodetector using the photogating effect. Turbostratic stacked CVD graphene was fabricated by multiple transfer processes. Graphene field effect transistor-based MWIR photodetectors were developed using an InSb substrate. The effect of the three layers of turbostratic stacked graphene enhanced both the field-effect mobility and MWIR response by approximately three times, compared to that of a conventional single-layer graphene photodetector in vacuum at 77 K. Our results may contribute to the realization of low-cost, mass-producible, high-responsivity graphene-based infrared sensors.
Comparison of HPLC and GC-MS for Measurement of Cocaine and Metabolites in Human Urine (1996)

High-performance liquid chromatography (HPLC) was compared with gas chromatography-mass spectrometry (GC-MS) for quantitation of cocaine, benzoylecgonine, norcocaine, and cocaethylene in urine. Calibration standards were prepared in human urine, and bupivacaine was added as the internal standard for quantitation. After solid-phase extraction, the reconstituted samples were divided into aliquots for analysis by HPLC and GC-MS. The analytical performance of the two methods were compared with regard to sensitivity, precision, and dynamic range. Results of GC-MS and HPLC analyses of nine urine specimens previously confirmed as positive for benzoylecgonine were compared. Analytical results by HPLC were comparable to GC-MS. Therefore, for many laboratories, HPLC is a useful alternative to GC-MS for measuring cocaine and metabolites in urine.
SIGNIFICANCE OF QUINONES IN THE CLASSIFICATION OF BACTERIA (1972)

Recently, instrumental analysis of metabolic products and cellular components have been applied to bacterial taxonomy. YAMADA et al. (1) already reported that the kind of quinones and the length of its isoprenoid side-chain may be used as a simple and effective criterion to distinguish the genera Gluconobacter and Acetobacter without exception. On the relation between gram stain and the kind of quinones, CRANE (2) described that only ubiqui none was found in the gram-negative bacteria, only menaquinone in the gram-positive bacteria, and both types of quinones in Escherichia coli and Proteus vulgaris, although his data were incomplete.

Intestinal permeability, digestive stability and oral bioavailability of dietary small RNAs (2018)

Impactful dietary RNA delivery requires improving uptake and enhancing digestive stability. In mouse feeding regimes, we have demonstrated that a plant-based ribosomal RNA (rRNA), MIR2911, is more bioavailable than synthetic MIR2911 or canonical microRNAs (miRNAs). Here mutagenesis was used to discern if MIR2911 has a distinctive sequence that aids stability and uptake. Various mutations had modest impacts while one scrambled sequence displayed significantly enhanced digestive stability, serum stability, and bioavailability. To assess if small RNA (sRNA) bioavailability in mice could be improved by increasing gut permeability, various diets, genetic backgrounds and pharmacological methods were surveyed. An intraperitoneal injection of anti-CD3 antibody enhanced gut permeability which correlated with improved uptake of the digestively stable scrambled MIR2911 variant. However, the bioavailability of canonical miRNAs was not enhanced. Similarly, interleukin-10 (IL-10)-deficient mice and mice treated with aspirin displayed enhanced gut permeability that did not enhance uptake of most plant-based sRNAs. This work supports a model where dietary RNAs are vulnerable to digestion and altering gut permeability alone will not impact apparent bioavailability. We suggest that some dietary sRNA may be more digestively stable and methods to broadly increase sRNA uptake requires delivery vehicles to optimize gut and serum stability in the consumer.
On Hydrogen Sulfide Evolution and Scavenging within SAGD Steam Chambers (2013)

Abstract In the Steam-Assisted Gravity Drainage (SAGD) thermal recovery process, high pressure and high temperature saturated-steam is injected into a bitumen-bearing oil sands formation. For most operations, the steam temperature ranges from about 200 to 260°C and thus under these conditions, the bitumen, in the presence of high temperature steam condensate, undergoes hydrous pyrolysis, i.e. aquathermolysis, yielding acid gases such as hydrogen sulfide and carbon dioxide. Current SAGD thermal reservoir simulation models in the literature often take into account complex spatial heterogeneity of the geology and oil composition and the physics of heat transfer, multiphase flow, gas solubility effects, and viscosity variations with temperature, however, few have taken the chemistry of SAGD into account. Here, we have added aquathermolysis reactions to thermal reservoir simulation model to understand reactive zones in the SAGD process and how the process generates acid gases via aquathermolysis. Given the requirement to constrain or handle sulfur emissions from thermal recovery processes, it is necessary to understand both the physical and chemical sides of the processes. Here, we have explored the possibility of triggering the Claus process underground for in situ scavenging of hydrogen sulfide during SAGD. The application of the research results is specifically to SAGD although the results could be extended to Cyclic Steam Stimulation as well. The results demonstrate that SAGD is not only a physical process that operates largely under gravity drainage but that it is also a chemically reactive process which generates hydrogen sulfide and carbon dioxide. The results also demonstrate that hydrogen sulfide generation reactions occur where there is sufficient heat, water, and oil and thus, the reactive zones are mainly at the edges of the steam chamber and in the liquid pool that sits above the production well. Injecting very small amount of sulfur dixode along with steam could result in initiation of Claus reaction underground resulting into conversion of hydrogen sulfide into liquid sulfur. The results of this study are significant given regulated emission limits of hydrogen sulfide from SAGD operations in Alberta, Canada, and moreover, the ability to potentially reduce emissions by altering the operating strategy or through in situ hydrogen sulfide scavengers offers an elegant way to meet these regulations.
1.2 µm highly strained GaInAs/GaAs quantumwell lasers for singlemode fibre datalink (1999)

The potential use of highly strained GaInAs/GaAs quantum well lasers in high capacity singlemode fibre datalinks is discussed. Heatsink-free CW operation of 1.2 µm GaInAs/GaAs ridge waveguide lasers is demonstrated, with a characteristic temperature T0 of 140 K. The lasing wavelength was &gt; 1.25 µm, which is the longest wavelength reported so far for GaInAs/GaAs systems. A preliminary experiment using 12 µm lasers for singlemode fibre data transmission is also performed.

High wholegrain barleyβ-glucan lowers food intake but does not alter small intestinal macronutrient digestibility in ileorectostomised rats (2016)

Using barley cultivars differing widely in β-glucan content, we aimed to determine their effects on small intestinal macronutrient digestion in 24 ileorectostomised rats. The rats were fed 1 of 4 experimental diets, each containing a different barley variety, for 11 d. The diets had a content of 0, 2.1, 2.6 and 4.3 g of β-glucan/100 g. Feed intake and faecal excretion of fat, protein, starch, and non-starch polysaccharides were determined in the final 5 d of the study and apparent macronutrient digestibility calculated. Higher dietary levels of β-glucan (2.6% and 4.3%) lowered feed intake (by 15 and 19%, respectively) but final body weight was only lowered by the 4.3% β-glucan diet relative to rats fed the 0% β-glucan diet (all ps < 0.05). Protein, lipid and starch digestibility was unrelated to the dietary β-glucan content. Higher dietary levels of barley β-glucan lower feed intake of ileorectostomised rats, which is independent of intestinal fermentation and unrelated to macronutrient digestibility.
Leveraging automatic speech recognition in cochlear implants for improved speech intelligibility under reverberation (2015)

Despite recent advancements in digital signal processing technology for cochlear implant (CI) devices, there still remains a significant gap between speech identification performance of CI users in reverberation compared to that in anechoic quiet conditions. Alternatively, automatic speech recognition (ASR) systems have seen significant improvements in recent years resulting in robust speech recognition in a variety of adverse environments, including reverberation. In this study, we exploit advancements seen in ASR technology for alternative formulated solutions to benefit CI users. Specifically, an ASR system is developed using multicondition training on speech data with different reverberation characteristics (e.g., T <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">60</inf> values), resulting in low word error rates (WER) in reverberant conditions. A speech synthesizer is then utilized to generate speech waveforms from the output of the ASR system, from which the synthesized speech is presented to CI listeners. The effectiveness of this hybrid recognition-synthesis CI strategy is evaluated under moderate to highly reverberant conditions (i.e., T <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">60</inf> = 0.3, 0.6, 0.8, and 1.0s) using speech material extracted from the TIMIT corpus. Experimental results confirm the effectiveness of multi-condition training on performance of the ASR system in reverberation, which consequently results in substantial speech intelligibility gains for CI users in reverberant environments.
Aerodynamic Characterization of New Parachute Configurations for Low-Density Deceleration (2013)

The Low Density Supersonic Decelerator project performed a wind tunnel experiment on the structural design and geometric porosity of various sub-scale parachutes in order to inform the design of the 110ft nominal diameter flight test canopy. Thirteen different parachute configurations, including disk-gap-band, ring sail, disk sail, and star sail canopies, were tested at the National Full-scale Aerodynamics Complex 80- by 120-foot Wind Tunnel at NASA Ames Research Center. Canopy drag load, dynamic pressure, and canopy position data were recorded in order to quantify there lative drag performance and stability of the various canopies. Desirable designs would yield increased drag above the disk-gap-band with similar, or improved, stability characteristics. Ring sail parachutes were tested at geometric porosities ranging from 10% to 22% with most of the porosity taken from the shoulder region near the canopy skirt. The disk sail canopy replaced the rings lot portion of the ring sail canopy with a flat circular disk and wastested at geometric porosities ranging from 9% to 19%. The star sail canopy replaced several ringsail gores with solid gores and was tested at 13% geometric porosity. Two disk sail configurations exhibited desirable properties such as an increase of 6-14% in the tangential force coefficient above the DGB with essentially equivalent stability. However, these data are presented with caveats including the inherent differences between wind tunnel and flight behavior and qualitative uncertainty in the aerodynamic coefficients.
A new cryogenic diode thermometer (2002)

While the introduction of yet another cryogenic diode thermometer is not earth shattering, a new diode thermometer, the DT-600 series, recently introduced by Lake Shore Cryotronics, possesses three features that make it unique among commercial diode thermometers. First, these diodes have been probed at the chip level, allowing for the availability of a bare chip thermometer matching a standard curve-an important feature in situations where real estate is at a premium (IR detectors), or where in-situ calibration is difficult. Second, the thermometry industry has assumed that interchangeability should be best at low temperatures. Thus, good interchangeability at room temperatures implies a very good interchangeability at cryogenic temperature, resulting in a premium priced sensor. The DT-600 series diode thermometer is available in an interchangeability band comparable to platinum RTDs with the added advantage of interchangeability to 2 K. Third, and most important, the DT-600 series diode does not exhibit an instability in the I-V characteristic in the 8 K to 20 K temperature range that is observed in other commercial diode thermometer devices [1]. This paper presents performance characteristics for the DT-600 series diode thermometer along with a comparison of I-V curves for this device and other commercial diode thermometers exhibiting an I-V instability.
Diagnostic errors in clinical microbiology and antimicrobial resistance (2019)

Antimicrobial resistance is a serious public health threat worldwide and is leading to resurgence of untreatable infectious diseases. However, AMR surveillance in low- and middle-income countries may not be of appropriate level. Optimum utilization of clinical microbiology services requires an integrated effort of several hospital services including supportive management and dedicated nursing staff. It requires regular and persistent motivation at all levels of the health care.
Delay optimal partitioning targeting low power VLSI circuits (1995)

Abstract: In this paper, a delay optimal clustering/partitioning algorithm for minimizing the power dissipation of a circuit is proposed. Traditional approaches for delay optimal partitioning are based on Lawler's clustering algorithm that makes no attempt to explore alternative partitioning solutions that have the same delay but better power implementations. Our algorithm provides a formal mechanism which implicitly enumerates alternate partitionings and selects a partitioning that has the same delay but less power dissipation. For tree circuits, the proposed algorithm produces delay and power optimal partitioning whereas for non-tree circuits it produces delay optimal partitioning with significantly improved power dissipation.
Synchronization and performance of MANET-based obstacle detection systems (2017)

The paper describes possible scenarios and transceivers structures for providing synchronization in MANET-based distributed radar and communication systems. Two approaches were reviewed in terms of performance and synchronization requirements for omnidirectional antennas: beam forming technique and synthesized radar aperture. The calculations show that the synchronization requirements could be softened by distributed use of sensing signals with unique sequence for each node. Designed structure is optimized with regard to obstacle detection method with Voronoy diagrams optimization and using simplex codes for providing energetical concealment. The chosen method allows generation of the digital map with accuracy up to 5 m on the distance of 5 km.
Growth of Loblolly Pine in the Arkansas Ozarks (1982)

Abstract A thinning and fertilizing study was established in an 11-year-old loblolly pine (Pinus taeda L.) plantation. Half of the plots were row thinned, removing 50 percent of the trees; plots were split and half were fertilized at a per acre rate of 100 pounds nitrogen, 50 pounds phosphorous and 50 pounds potassium. There was no response of height, d.b.h. or volume growth to fertilizer. Thinning increased diameter growth but decreased volume growth. The trees have shown exceptional growth. At age 17 the height was 49 feet, d.b.h. 7.3 inches and stocking 2,490 cubic feet on the thinned plots. The respective values for the unthinned plots were 48 feet, 6.7 inches, and 3,960 cubic feet.
