Effect of high voltage stress on the DC performance of the Al<sub>2</sub>O<sub>3</sub>/AlN GaN metal–insulator–semiconductor high-electron mobility transistor for power applications (2015)

We demonstrate an Al2O3/AlN/AlGaN/GaN metal–insulator–semiconductor high-electron mobility transistor (MIS-HEMT) device with stable electrical properties under high-voltage stress, by using an Al2O3/AlN stack layer as the gate dielectric layer. Excellent quality AlN/Al2O3 GaN interface was obtained by using plasma-enhanced ALD (PE-ALD), resulting in a very low interface trap density (Dit) of ∼1.8 × 1011 eV−1 cm−2, obtained by using the conductance method. The device exhibits a small threshold voltage hysteresis of ∼200 mV and a lower gate–source leakage current. No obvious changes in the drain–source current and ON-resistance were observed for the device that was subject to the drain–source voltage stress of 100 V for 15 h.

Forests trapped in nitrogen limitation – an ecological market perspective on ectomycorrhizal symbiosis (2014)

Ectomycorrhizal symbiosis is omnipresent in boreal forests, where it is assumed to benefit plant growth. However, experiments show inconsistent benefits for plants and volatility of individual partnerships, which calls for a re-evaluation of the presumed role of this symbiosis. We reconcile these inconsistencies by developing a model that demonstrates how mycorrhizal networking and market mechanisms shape the strategies of individual plants and fungi to promote symbiotic stability at the ecosystem level. The model predicts that plants switch abruptly from a mixed strategy with both mycorrhizal and nonmycorrhizal roots to a purely mycorrhizal strategy as soil nitrogen availability declines, in agreement with the frequency distribution of ectomycorrhizal colonization intensity across a wide-ranging data set. In line with observations in field-scale isotope labeling experiments, the model explains why ectomycorrhizal symbiosis does not alleviate plant nitrogen limitation. Instead, market mechanisms may generate self-stabilization of the mycorrhizal strategy via nitrogen depletion feedback, even if plant growth is ultimately reduced. We suggest that this feedback mechanism maintains the strong nitrogen limitation ubiquitous in boreal forests. The mechanism may also have the capacity to eliminate or even reverse the expected positive effect of rising CO2 on tree growth in strongly nitrogen-limited boreal forests.
The Effect of Bacterial, Viral and Fungal Infection on Mast Cell Reactivity in the Allergic Setting (2011)

Mast cells are well known for their role in allergic inflammation where, upon aggregation of the high-affinity immunoglobulin E receptor, they release mediators such as histamine that cause classical allergic symptoms. Mast cells are located in almost all tissues and are especially numerous in organs that interface with the environment. Given this strategic location and the more recent notion that they are endowed with receptors that recognize endogenous and exogenous danger signals such as pathogens, it is not surprising that they function as important cells in immune surveillance. When mast cells are activated by pathogens they modulate innate and adaptive immune responses. In allergy, infections might cause exacerbation of the allergic reaction by affecting the reactivity of mast cells. With new developments within the field of mast cell biology, we will better understand how mast cells execute their effector functions. This knowledge will also help to improve the management of allergic diseases.
Evaluating the culture of fetal erythroblasts from maternal blood for non-invasive prenatal diagnosis (1998)

Fetal erythroblasts circulating in maternal blood are important candidate cells for non-invasive prenatal diagnosis. We have cultured erythroblasts from 16 maternal blood samples, both with and without prior enrichment by magnetic activated cell sorting (MACS), in a semi-solid medium containing growth factors. Individual colonies were examined by PCR with sex chromosome-specific primers and microsatellite marker primers. No conclusive Y-chromosome specific amplification could be demonstrated in any of the 16 cases, even when the mother was confirmed to be carrying a male fetus. All colonies tested by microsatellite marker PCR were of maternal origin. Our results suggest that the probability of obtaining fetal colonies from fetal erythroblasts circulating in maternal blood is very low and that approaches for culturing fetal erythroblasts in vitro cannot yet be used reliably for prenatal diagnosis using current methods for fetal cell enrichment.

On polarization metrology (estimation) of the degree of coherence of optical waves (2009)

A new approach is proposed for estimating the degree of coherence of optical waves. The possibility of transformation of the spatial polarization distribution in the measured spatial intensity distribution for determining the degree of correlation of superposing waves, linearly polarized in the plane of incidence, is shown.
Backward diffraction of the light by the phase-transmission holographic grating (1991)

Backward diffraction of the plain wave by the transmission holographic grating is considered theoretically using singular perturbation method. The formulae for the intensities of the most strong reflected orders are found and discussed. The physical nature of backward diffraction is explained using the multylayers model of scattering. 2.

Effect of Aquifer Turbulence on Well Drawdown (1959)

The change from laminar flow to turbulent flow, in the case of water flowing through sand, occurs over a wide transition zone beginning with a Reynolds number of about 10. A method for estimating the exponent of the velocity term for head loss calculations involving flow into wells is presented. Typical calculations show that head losses due to aquifer turbulence may have been over-estimated in previously published material.
Across-Gimbal and Miniaturized Cryogenic Loop Heat Pipes (2003)

This paper describes the development status of three advanced cryogenic loop heat pipes (CLHP) for solving important problems in cryogenic integration. The three devices described herein are: (1) an across‐gimbal CLHP; (2) a short transport length miniaturized CLHP; and (3) a long transport length miniaturized CLHP. The across‐gimbal CLHP, which is baselined for operation from 80–100 K with nitrogen, provides a low weight, low torque, high conductance solution for gimbaled cryogenic systems wishing to mount their cryocoolers off‐gimbal. The short transport length miniaturized CLHP, which is baselined for operation near 35 K with neon, combines localized thermal transport, flexibility, and thermal switching into one device that can be directly mounted to a cryocooler cold head and a cryogenic component just a short distance (10–20 cm) away. The long transport length miniaturized CLHP, which is also baselined for operation near 35 K with neon, adds to the capabilities of the short transport length miniaturized CLHP by increasing the transport length to over 250 cm to meet cryogenic heat transport device requirements of future NASA and DoD spacecraft.
Effect of Intracavernous Simultaneous Injection of Acetylcholine and Vasoactive Intestinal Polypeptide on Canine Penile Erection (1992)

We investigated the effects of intracavernous injection of a combination of acetylcholine (ACh) and vasoactive intestinal polypeptide (VIP) on the erectile response in eleven adult male dogs. The minimum dose of ACh which increased the intracavernous pressure in eight dogs varied from 0.2 to 40 micrograms, and the minimum dose of VIP varied from 0.2 to 5 micrograms. When the minimum doses of ACh and VIP were injected simultaneously, a strong increase of intracavernous pressure (the mean increase was 102 cm. H2O from the baseline level) and a sustained erection (mean 5 min.) were observed in all eight dogs. The effect of simultaneous injection of both drugs was not additive but synergistic. Pretreatment with VIP-antibody and atropine intracavernously suppressed the erectile response induced by cavernous nerve stimulation. VIP may increase the affinity of muscarinic receptors for ACh in canine corpus cavernosum because pretreatment with atropine alone before the simultaneous injection of ACh and VIP completely abolished the effect of the combination. We conclude that ACh and VIP may play a cooperative role in canine penile erection.

Specific activation of AP‐1 but not Stat3 in regenerating liver in mice (1997)

Liver regeneration following partial hepatectomy is regulated by hepatotrophic factors whose precise roles are still elusive. In cell culture studies, some of them have been shown to activate members of the family of the signal transducers and activators of transcription (Stat). To test this contention in vivo, nuclear extracts were isolated from livers of partially hepatectomized and sham-operated mice killed at 30 different time points between zero and 108 h after surgery. Stat3 DNA binding is rapidly induced after surgery in both partially hepatectomized and sham-operated mice. Maximum activation of Stat3 is achieved 4-6 h after resection, and elevated Stat3 activation is detected as late as 60 h after surgery in both groups. Activated Stat5 is found sporadically in both sham-operated and resected mice but appears to be absent in the first 12 h after partial hepatectomy. Neither Stat1, Stat2, Stat4 nor Stat6 is induced during the time of observation. In contrast, AP-1 DNA binding activity is specifically induced in regenerating mouse liver.
Removal of Lattice Imperfections that Impact the Optical Quality of Ti:Sapphire using Advanced Magnetorheological Finishing Techniques (2008)

Advanced magnetorheological finishing (MRF) techniques have been applied to Ti:sapphire crystals to compensate for sub-millimeter lattice distortions that occur during the crystal growing process. Precise optical corrections are made by imprinting topographical structure onto the crystal surfaces to cancel out the effects of the lattice distortion in the transmitted wavefront. This novel technique significantly improves the optical quality for crystals of this type and sets the stage for increasing the availability of high-quality large-aperture sapphire and Ti:sapphire optics in critical applications.
Maude as a Metalanguage (1998)

One of the key goals of rewriting logic from its beginning has been to provide a semantic and logical framework in which many models of computation and languages can be naturally represented. There is by now very extensive evidence supporting the claim that rewriting logic is indeed a very flexible and simple logical and semantic framework. From a language design point of view the obvious question to ask is: how can a rewriting logic language best support logical and semantic framework applications, so that it becomes a metalanguage in which a very wide variety of logics and languages can be both semantically defined, and implemented? Our answer is: by being reflective. This paper discusses our latest language design and implementation work on Maude as a reflective metalanguage in which entire environments---including syntax definition, parsing, pretty printing, execution, and input/output---can be defined for a language or logic £ of choice.

Observations of the Dynamics and Acoustics of Attached Cavities (1990)

In this study of attached cavities on an axisymmetric headform, measurements were made of the noise generated by the cavitation. In addition to hydrophone recordings, a new technique employing flush mounted electrodes was used to measure the steady state and dynamic volume fluctuations of the attached cavities. The spectra of the noise are quite featureless and show some decrease in the high frequency content as the cavities become larger. However, the spectra from the electrode measurement show some distinct frequencies of fluctuation.
Screening Colonoscopies by Primary Care Physicians: A Meta-Analysis (2009)

Colonoscopies performed by primary care physicians have quality, safety, and efficacy indicators that are comparable to those recommended by the American Society of Gastrointestinal Endoscopy, the American College of Gastroenterology, and the Society of American Gastrointestinal Endoscopic Surgeons. Based on these results, colonoscopy screening by primary care physicians appears to be safe and effective.
Mining Large-scale TV Group Viewing Patterns for Group Recommendation (2013)

We present a large-scale study of television viewing habits, focusing on how individuals adapt their preferences when consuming content in group settings. While there has been a great deal of recent work on modeling individual preferences, there has been considerably less work studying the behavior and preferences of groups, due mostly to the difficulty of data collection in these settings. In contrast to past work that has relied either on small-scale surveys or prototypes, we explore more than 4 million logged views paired with individual-level demographic and co-viewing information to uncover variation in the viewing patterns of individuals and groups. Our analysis reveals which genres are popular among specific demographic groups when viewed individually, how often individuals from different demographic categories participate in group viewing, and how viewing patterns change in various group contexts. Furthermore, we leverage this large-scale dataset to directly estimate how individual preferences are combined in group settings, finding subtle deviations from traditional preference aggregation functions. We present a simple model which captures these effects and discuss the impact of these findings on the design of group recommendation systems. 1.
Valid Assessment of Writing and Access to Academic Discourse (1997)

One way to improve students' access to and retention in post-secondary degree progams is to assess their readiness for such programs accurately. To place deaf and hard-of-hearing students in preparatory courses and to determine their readiness for degree programs more accurately, a direct measure of writing was developed for deaf and hard-of-hearing students at a large technical university. The purpose of this study was to estimate the concurrent and predictive validity of this measure. The Test of Written English (Educational Testing Service, 1992) served as the criterion in the concurrent validity study, and student success in the university's gateway freshman composition course served as the criterion in the predictive validity study. Results provide evidence of the concurrent and predictive validity of the measure, supporting its use for course placement and early planning purposes.
Dissolved oxygen sensor film using ruthenium polypyridine complex as luminophore (2013)

Ruthenium polypyridine complex was synthesized by using RAFT process. The Ruthenium was immobilized in 2 silicone matrices, polydimethylsiloxane(PDMS) and KE 200 (silicone elastomer base)/CX200 (curing agent). KE 200/CX200 is the alcohols curing type silicone. Both sensor films showed absorption peak at 460 nm and luminescence peak at 610 nm. The KE200/CX200 film gave linear response to dissolved oxygen up to 80% O2 (18 ppm) follow Stern-Volmer equation with R 2 of 0.990. The measured luminescence intensity decreased with increasing dissolved oxygen water temperature from 25 to 70c. After being irradiated with 460 nm light source for 3 hrs, the sensor film still showed good stability.
Iron metabolism in BeWo chorion carcinoma cells. Transferrin-mediated uptake and release of iron. (1987)

Growing human choriocarcinoma BeWo b24 cells contain 1.5 X 10(6) functional cell surface transferrin binding sites and 2.0 X 10(6) intracellular binding sites. These cells rapidly accumulate iron at a rate of 360,000 iron atoms/min/cell. During iron uptake the transferrin and its receptor recycle at least each 19 min. The accumulated iron is released from the BeWo cells at a considerable rate. The time required to release 50% of previously accumulated iron into the extracellular medium is 30 h. This release process is cell line-specific as HeLa cells release very little if any iron. The release of iron by BeWo cells is stimulated by exogenous chelators such as apotransferrin, diethylenetriaminepenta-acetic acid, desferral, and apolactoferrin. The time required to release 50% of the previously accumulated iron into medium supplemented with chelator is 15 h. In the absence of added chelators iron is released as a low molecular weight complex, whereas in the presence of chelator the iron is found complexed to the chelator. Uptake of iron is inhibited by 250 microM primaquine or 2.5 microM monensin. However, the release of iron is not inhibited by these drugs. Intracellular iron is stored bound to ferritin. A model for the release of iron by BeWo cells and its implication for transplacental iron transport is discussed.

<i>In vitro</i> DIFFERENTIATION OF A MOUSE NEUROBLASTOMA (1969)

Mouse tumor C1300 has been established in tissue culture. The cells have a round cell morphology in both the subcutaneous tumor and in suspension culture. However, when given a surface on which to attach, they send out processes up to 3 mm in length and assume the morphology of mature neurons. The attached cells are stained by the Bodian silver procedure for neurons, whereas the cells grown in suspension are not. Electron microscopy reveals that the attached cells contain neurofilaments, neurotubules, and densecore vesicles indicative of nerve fibers. Both free-floating and attached cells have tyrosine hydroxylase activity characteristic of sympathetic nervous tissue. Apparently cell attachment can induce morphological differentiation from an anaplastic round cell to a cell which has many properties of a mature neuron.
<i>Pseudomonas aeruginosa</i> aliphatic amidase is related to the nitrilase/cyanide hydratase enzyme family and Cys<sup>166</sup> is predicted to be the active site nucleophile of the catalytic mechanism (1995)

A database search indicated homology between some members of the nitrilase/cyanide hydratase family, Pseudomonas aeruginosa and Rhodococcus erythropolis amidases and several other proteins, some of unknown function. BLOCK and PROFILE searches confirmed these relationships and showed that four regions of the P. aeruginosa amidase had significant homology with corresponding regions of nitrilases. A phylogenetic tree placed the P. aeruginosa and R. erythropolis amidases in a group with nitrilases but separated other amidases into three groups. The active site cysteine in nitrilases is conserved in the P. aeruginosa amidase indicating that Cys166 is the active site nucleophile.
First tests of the coronagraphic device of MIRI/JWST (2008)

One of the main objectives of the instrument MIRI, the Mid-InfraRed Instrument, of the JWST is the direct detection and characterization of extrasolar giant planets. For that purpose, a coronagraphic device including three Four-Quadrant Phase Masks and a Lyot coronagraph working in mid-infrared, has been developed. We present here the results of the first test campaign of the coronagraphic system in the mid-infrared in the facility developed at the CEA. The performances are compared to the expected ones from the coronagraphic simulations. The accuracy of the centering procedures is also evaluated to validate the choice of the on-board centering algorithm.
Analog Beam Tracking in Linear Antenna Arrays: Convergence, Optimality, and Performance (2017)

The directionality of millimeter-wave (mmWave) communications creates a significant challenge in serving fast-moving mobile terminals on, e.g., high-speed vehicles, trains, and UAVs. This challenge is exacerbated in mmWave systems using analog antenna arrays, because of the inherent non-convexity in the control of the phase shifters. In this paper, we develop a recursive beam tracking algorithm which can simultaneously achieve fast tracking speed, high tracking accuracy, low complexity, and low pilot overhead. In static scenarios, this algorithm converges to the minimum Cramér-Rao lower bound (CRLB) of beam tracking with high probability. In dynamic scenarios, even at SNRs as low as 0dB, our algorithm is capable of tracking a mobile moving randomly at an absolute angular velocity of 10-20 degrees per second, using only 5 pilot symbols per second. If combining with a simple TDMA pilot pattern, this algorithm can track hundreds of high-speed mobiles in 5G configurations. Our simulations show that the tracking performance of this algorithm is much better than several state-of-the-art algorithms.
