Decrease of Human Serum Fucosyltransferase as an Indicator of Successful Tumor Therapy (1978)

Surgical removal of colon carcinomas leads to a decrease in the rate of incorporation of [ 14 C]fucose into its endogenous acceptor in human serum; normal incorporation rates are attained within 14 days. A similar time course has been determined for α 2 - and α 3 -fucosyltransferase when either desialo- or desialodegalactofetuin are employed as exogenous acceptors. A correlation has also been seen between transferase activity and the therapeutic response of patients with breast cancer. These results indicate that the determination of fucosyltransferase activity can facilitate the diagnosis of neoplasia, and the success of surgery, chemotherapy, or radiation.
Modeling of the energy of a smelt-water explosion in the recovery boiler dissolving tank (2020)

The explosion energy generated as molten smelt droplets interact with water was evaluated as a function of smelt distribution, water temperature, and smelt temperature using a thermodynamic model. The results show that increasing smelt-to-water volume ratio and water temperature significantly increases the explosion energy, converting a larger proportion of the thermal energy of smelt into mechanical work. To reduce the chance of violent smelt-water explosions, it is important to: i) optimize the shatter jet design and operation to uniformly distribute the smelt over a large area in the dissolving tank; ii) avoid high green liquor temperature and ensure adequate liquor mixing; and iii) avoid upsets that may cause heavy smelt runoff or jellyroll smelt.
Radiation and ohmic resistances in very small meander line antennas of less than 0.1 wavelength (2005)

Abstract Demands for extremely small antennas to be used in radiofrequency identification tags for ubiquitous communication have increased. Examples of very small antennas utilizing meander line structures are seen. To date, important studies have been carried out on basic design and on improvement of the radiation efficiency by a folded configuration. Most of the structures studied have dimensions of more than 0.1 wavelength. For the demands of ultracompact antennas, this paper deals with meander line antennas whose dimensions are less than 0.1 wavelength. First, the parameters for resonant configurations are derived for antennas with dimensions of 0.1 to 0.025 wavelength. Next, the radiation resistance and the ohmic resistance are studied in the folded structures. First, through a transmission line model analysis, it is shown that the step‐up ratios of radiation and ohmic resistances in the case of folded structures are different. In addition, these resistances that are basic values of electrical performances are derived through electromagnetic simulations. Further, in order to confirm the validity of the numerical results and the realizable performance, antennas with dimensions of 0.1 and 0.05 wavelength were fabricated. Electrical characteristics are compared, and good agreements are found. © 2005 Wiley Periodicals, Inc.

Recent Progress in Zirconia-Based Fuel Cells for Power Generation (2023)

High temperature solid oxide fuel cells based upon yttria-stabilized zirconia electrolyte offer a clean, pollution-free technology to electrochemically generate electricity at high efficiencies. This paper reviews the designs, materials and fabrication processes used for such fuel cells. Most progress to date has been achieved with tubular geometry cells. A large number of tubular cells have been electrically tested, some to times up to 30,000 hours; these cells have shown excellent performance and performance stability. In addition, successively larger size electric generators utilizing these cells have been designed, built and operated since 1984. Two 25 kW power generation field test units have recently been fabricated; these units represent a major milestone in the commercialization of zirconia-based fuel cells for power generation.
RESISTANCE OF CERAMICS TO PENETRATION AT IMPACT VELOCITIES ABOVE 5 Km/S (1991)

The resistance of ceramics to penetration at velocities exceeding crack propagation velocities has been studied. The strength resistance of ceramics is found to be as high as several tens GPa. At high penetration velocities, which exclud the weakening of a brittle target due to crack growth, the plastic flow of ceramics is to be occured. Then, the ceramics strength resistance is to be identified as the dynamic hardness. The nature of realization of strength properties is the same both for metals and ceramics. As to resistance to penetration, ceramics differ from metals, as dynamic hardness of ceramics is about one order of magnitude higher as compared to metals. As a result, the inertial resistance of the ceramic targets to penetration becomes supplemented by the strength resistance of ceramics. It follows that high-velocity penetration of ceramic targets differ from the hydrodynamic model.

A low-jitter wide-range skew-calibrated dual-loop DLL using antifuse circuitry for high-speed DRAM (2002)

This paper describes a delay-locked loop (DLL) circuit having two advancements, a dual-loop operation for a wide lock range and programmable replica delays using antifuse circuitry and internal voltage generator for a post-package skew calibration. The dual-loop operation uses information from the initial time difference between reference clock and internal clock to select one of the differential internal loops. This increases the lock range of the DLL to the lower frequency. In addition, incorporation of the programmable replica delay using antifuse circuitry and the internal voltage generator allows for the elimination of skews between external clock and internal clock that occur from on-chip and off-chip variations after the package process. The proposed DLL, fabricated on 0.16-/spl mu/m DRAM process, operates over the wide range of 42-400 MHz with 2.3-V power supply. The measured results show 43-ps peak-to-peak jitter and 4.71-ps rms jitter consuming 52 mW at 400 MHz.
Lipid Emulsions as Contrast Agents for Hepatic Sonography: An Experimental Study in Rabbits (1985)

An ultrasound contrast agent capable of increasing hepatic echogenicity would be useful for the detection of hepatic tumors and metastases. Fatty liver is known to produce increased liver echogenicity. Intravenously administered lipid emulsions are phagocytosed by cells of the reticuloendothelial system the liver with transient hepatic lipid accumulation. We examined the effectiveness of three lipid emulsions of differing particle size as potential ultrasound contrast agents using a rabbit liver model. None of the tested emulsions showed any consistent ability to alter liver echogenicity at maximum tolerable doses. Lipid emulsions do not appear to have potential as contrast agents for ultrasound examination of the liver.

Scanning strategies for imaging arrays (2008)

Large-format (sub)millimeter wavelength imaging arrays are best operated in scanning observing modes rather than traditional position-switched (chopped) modes. The choice of observing mode is critical for isolating source signals from various types of noise interference, especially for ground-based instrumentation operating under a bright atmosphere. Ideal observing strategies can combat 1/<i>f</i> noise, resist instrumental defects, sensitively recover emission on large scales, and provide an even field coverage - all under feasible requirements of telescope movement. This work aims to guide the design of observing patterns that maximize scientific returns. It also compares some of the popular choices of observing modes for (sub)millimeter imaging, such as random, Lissajous, billiard, spiral, On-The-Fly (OTF), DREAM, chopped and stare patterns. Many of the conclusions are also applicable other imaging applications and imaging in one dimension (e.g. spectroscopic observations).

Cuestiones tales como el procedimiento de regulacion de empleo, la clasificacion y pago de creditos laborales o el incidente concursal laboral, y, especialmente, los efectos laborales de la venta de la unidad productiva, requieren un nuevo estudio al que intentare aproximarme con unas breves notas.
A 1H/15N n.m.r. study of nitrogen metabolism in cultured mammalian cells (1993)

1. Heteronuclear 1H/15N n.m.r. experiments are described in which 15N labelling of cellular metabolites is detected via their proton resonances. 2. These n.m.r. experiments have been used to monitor label redistribution amongst extracellular metabolites in cultures of mammalian cells incubated with L-[2-15N]glutamine, L-[5-15N]glutamine and 15NH4Cl. Label redistribution was monitored in two HeLa cell lines and in two CHO cell lines which showed a range of extractable activities of glutamate dehydrogenase, glutaminase and glutamine synthetase. 3. In cells incubated with L-[2-15N]glutamine the 15N label was subsequently found in a number of metabolites including alanine, aspartate, glycine and pyrrolidone-5-carboxylic acid. There was no detectable production of 15NH4+, showing that most of the glutamate formed in the reaction catalysed by glutaminase was subsequently transaminated rather than oxidatively deaminated by glutamate dehydrogenase. 4. Incubation of cells with L-[5-15N]glutamine showed that the ammonia in the cultures was derived predominantly from the amide group of glutamine. 5. The rate of formation of L-[5-15N]glutamine in cells incubated with 15NH4Cl was used to estimate glutamine synthetase flux in vivo. Flux in this reaction was only observable in the two CHO cell lines which express relatively high levels of the enzyme.
LLL Reduction Achieves the Receive Diversity in MIMO Decoding (2007)

Diversity order is an important measure for the performance of communication systems over multiple-input-multiple-output (MIMO) fading channels. In this correspondence, we prove that in MIMO multiple- access systems (or MIMO point-to-point systems with V-BLAST transmission), lattice-reduction-aided decoding achieves the maximum receive diversity (which is equal to the number of receive antennas). Also, we prove that the naive lattice decoding (which discards the out-of-region decoded points) achieves the maximum diversity.
Swept source optical coherence microscopy using a Fourier domain mode-locked laser (2007)

Swept source optical coherence microscopy (OCM) enables cellular resolution en face imaging as well as integration with optical coherence tomography (OCT) cross sectional imaging. A buffered Fourier domain mode-locked (FDML) laser light source provides high speed, three dimensional imaging. Image resolutions of 1.6 microm x 8 microm (transverse x axial) with a 220 microm x 220 microm field of view and sensitivity higher than 98 dB are achieved. Three dimensional cellular imaging is demonstrated in vivo in the Xenopus laevis tadpole and ex vivo in the rat kidney and human colon.
A Linear Lignin Analogue:  Phenolic Alternating Copolymers from Naturally Occurring β-Methylstyrene via Aqueous-Controlled Cationic Copolymerization (2007)

From naturally occurring β-methylstyrenes, such as anethole and isoeugenol, a bio-based copolymer was prepared by the controlled cationic copolymerization with the alcohol/BF3OEt2 initiating system in an aqueous solvent. The copolymerizations with p-methoxystyrene proceeded in a living fashion, in which the molecular weights and molecular weight distributions of the resulting copolymers were controlled. Specifically, isoeugenol can be copolymerized without protection of the phenolic moiety to give an almost alternating copolymer, which can be regarded as a well-defined linear lignin analogue with the functional 4-hydroxy-3-methoxyphenyl groups.
Empirical Studies on English Vocabulary Learning Strategies in Mainland China over the Past Two Decades (2015)

Wen and Wang (2004) reviewed the empirical studies over the past two decades (from 1984 to 2003) on learning strategies that Chinese EFL learners used. This article, following their methodological framework, reviews about 45 empirical studies on Chinese EFL learners’ English vocabulary learning strategies, conducted by Mainland Chinese scholars over the past two decades. The review shows that more than half of the Chinese scholars are interested in questionnaire investigation of EFL learners’ preferences for vocabulary learning. The reports of the questionnaire investigations indicate that most Chinese EFL learners prefer rote learning of vocabulary to learning vocabulary in context or through language use. The experimental studies suggest that strategies-based instruction results in the learners’ vocabulary achievement. Cognitive and metacognitive strategies are the two groups of strategies that Chinese researchers show particular interest in.
Titanium Powder from the TiRO™ Process (2012)

A new continuous process for the direct production of CP titanium powder is being developed at CSIRO. The TiRO™ process has two major steps. The first step is conducted in a fluidised bed where titanium tetrachloride and magnesium powder react to form small (1.5 µm) titanium metal particles uniformly dispersed inside larger spheroidal magnesium chloride particles with an average particle size of 350 µm. The second step involves vacuum distillation in which the magnesium chloride is removed from the titanium. During vacuum distillation the magnesium chloride is volatilised and the micron sized titanium particles come together to form partially sintered predominantly spheroidal porous particles with a similar shape to the starting particle, some which appeared to be hollow. A mechanism for their formation is proposed. The spheroidal particles are all lightly sintered together. The vacuum distilled product was very lightly ground to liberate the spheroidal particles which had an average particle size of about 200 µm. With further grinding an angular Ti powder was produced. The ground titanium was free flowing and had a tap density of 2.4 g/cm3.
Mechanical Circulatory Support for Right Heart Failure: Current Technology and Future Outlook (2011)

The increasing global prevalence of congestive heart failure is a major healthcare concern, accounting for a high morbidity rate worldwide. In particular, isolated right heart dysfunction after cardiotomy has a poor prognosis and is associated with a high mortality rate. The occurrence of postoperative right heart failure may develop in more than 40% of patients undergoing implantation of a left ventricular assist device (LVAD) and cardiac transplantation. To date, mechanical cardiac assistance in the form of VADs has become accepted as a therapeutic solution for end-stage patients when a donor heart is not available. However, right ventricular (RV) assistance is still in the early phase of development when compared with LVAD technology. State-of-the-art RVADs, both in clinical use and under development, are reviewed in this manuscript. Clinical RVADs include the extracorporeal pulsatile Abiomed BVS 5000 and AB5000, Thoratec PVAD, MEDOS VAD, BerlinHeart Excor, the percutaneous continuous flow CentriMag and TandemHeart systems, and the implantable Thoratec IVAD. Devices on the horizon, including the wear-free implantable DexAide and the minimally invasive Impella RD, are additionally reviewed. In addition to the current status of RV assistance, as well as the device categorization, the outlook and considerations for successful development of future RVADs were discussed.
Optical Interfaces for Silicon Photonic Circuits (2018)

Efficient optical interfaces are challenging due to the micrometer-scale wavelength of light. We provide an overview and classification of the most successful and most promising optical interface methods used for silicon photonic integrated circuits. Coupling interfaces can be divided into three main categories: chip-to-chip, fiber-to-chip, and free-space-to-chip. Depending on this interface and the application, one can opt for a diffraction-based grating coupler or a mode-evolution-based edge coupler. The functional, performance, design, development, packaging, and cost tradeoffs for each method are discussed. We then analyze the recent development of arraying optical emitting elements in optical phased arrays for free-space applications such as LiDAR and data communication.
Point defects in two-dimensional hexagonal boron nitride: A perspective (2020)

Two-dimensional (2D) hexagonal boron nitride (h-BN) is one of the most promising materials for many technological applications ranging from optics to electronics. In past years, a property-tunable strategy that involves the construction of electronic structures of h-BN through an atomic-level design of point defects has been in vogue. The point defects imported during material synthesis or functionalization by defect engineering can endow h-BN with new physical characteristics and applications. In this Perspective, we survey the current state of the art in multifunction variations induced by point defects for 2D h-BN. We begin with an introduction of the band structure and electronic property of the pristine h-BN. Subsequently, the formation and characterization of the most obvious point defects and their modulation in electronic structures of h-BN nanomaterials are envisaged in theory. The experimental results obtained by atom-resolved transmission electron microscopy, magnetic measurement, and optical measurements have provided insights into the point defect engineered structures and their corresponding emerging properties. Finally, we highlight the perspectives of h-BN nanomaterials for heterostructures and devices. This Perspective provides a landscape of the point defect physics involved to demonstrate the modulation of the structure and functionalities in h-BN and identify the roadmap for heterostructure and device applications, which will make advances in electronics, spintronics, and nanophotonics.
Association between e-alert implementation for detection of acute kidney injury and outcomes: a systematic review (2016)

In the available studies, e-alerts for AKI do not improve survival or reduce RRT utilization. The impact of e-alerts on processes of care was variable. Additional research is needed to understand those aspects of e-alerts that are most likely to improve care processes and outcomes.
Fermi's golden rule does not adequately describe Dicke's superradiance (2008)

We consider the application of Fermi's golden rule to the problem of N atoms, one of which is excited, in an extended medium with dimensions that are large compared with the wavelength. We find that, in contrast to an often-voiced opinion, the golden rule does not describe the physics of one photon absorbed and subsequently emitted by N atoms. The correct treatment includes many-body effects such as Fano interference. For a finite atomic cloud with size R, in the Markovian limit, the system will decay exponentially at a rate of around N(λ2/R 2) faster than the single-atom decay rate.
The Menkes/Wilson disease gene homologue in yeast provides copper to a ceruloplasmin-like oxidase required for iron uptake. (1995)

The CCC2 gene of the yeast Saccharomyces cerevisiae is homologous to the human genes defective in Wilson disease and Menkes disease. A biochemical hallmark of these diseases is a deficiency of copper in ceruloplasmin and other copper proteins found in extracytosolic compartments. Here we demonstrate that disruption of the yeast CCC2 gene results in defects in respiration and iron uptake. These defects could be reversed by supplementing cells with copper, suggesting that CCC2 mutant cells were copper deficient. However, cytosolic copper levels and copper uptake were normal. Instead, CCC2 mutant cells lacked a copper-dependent oxidase activity associated with the extracytosolic domain of the FET3-encoded protein, a ceruloplasmin homologue previously shown to be necessary for high-affinity iron uptake in yeast. Copper restored oxidase activity both in vitro and in vivo, paralleling the ability of copper to restore respiration and iron uptake. These results suggest that the CCC2-encoded protein is required for the export of copper from the cytosol into an extracytosolic compartment, supporting the proposal that intracellular copper transport is impaired in Wilson disease and Menkes disease.
Analysis of microRNAs and their precursors in bovine early embryonic development (2012)

In animals, the maternal-to-embryonic transition (MET) occurs in the first days of early development and involves the degradation of maternal transcripts that have been stored during oogenesis. Moreover, precise and specific control mechanisms govern the adequate synchronization of the MET events to promote the activation of the embryonic genome. These mechanisms are not well understood, but it is believed that microRNAs (miRNAs) could be one of the mechanisms involved. After a microarray screening study, we analysed the expression of specific miRNA during oocyte maturation and early embryo development until preimplantation stages. Two differentially expressed candidates were selected for further analysis. Mature and precursor forms of miR-21 and miR-130a were quantified by qRT-PCR in pools of 20 oocytes at GV (germinal vesicle), GV breakdown and metaphase II stages as well as in pools of embryos at the 2-cell, 4-cell, 8-cell and blastocyst stages. The results showed a linear increase during the 1-8 cell stage for the mature forms of miR-130a and miR-21 (P < 0.05 and P < 0.003, respectively) and for the precursor form of miR-130a (P < 0.002). To see if this increase was due to minor transcriptional activity, 2-cell embryos were exposed to α-amanitin for 30-34 h. Results showed a significant decrease in miR-21, pre-miR-21, miR-130a and SRFS3 in α-amanitin-treated embryos (P < 0.05). Considering the potential regulatory role of these miRNA, the bovine genome was screened to identify putative targets with a 3'UTR exact seed match. This study suggests that miRNAs could be important players in the MET, as expression profiles suggest a potential regulation role during early development steps.
Membrane Traffic Within the Golgi Apparatus (2009)

Newly synthesized secretory cargo molecules pass through the Golgi apparatus while resident Golgi proteins remain in the organelle. However, the pathways of membrane traffic within the Golgi are still uncertain. Most of the available data can be accommodated by the cisternal maturation model, which postulates that Golgi cisternae form de novo, carry secretory cargoes forward and ultimately disappear. The entry face of the Golgi receives material that has been exported from transitional endoplasmic reticulum sites, and the exit face of the Golgi is intimately connected with endocytic compartments. These conserved features are enhanced by cell-type-specific elaborations such as tubular connections between mammalian Golgi cisternae. Key mechanistic questions remain about the formation and maturation of Golgi cisternae, the recycling of resident Golgi proteins, the origins of Golgi compartmental identity, the establishment of Golgi architecture, and the roles of Golgi structural elements in membrane traffic.
