Dynamic nanoindentation of some polyolefins (2006)

Abstract Nanoindentation tests have been conducted on five different polyolefins, comprising a high density polyethylene, a low density polyethylene, a linear low density polyethylene, a polypropylene homopolymer and a polypropylene copolymer. The nanoindenter was fitted with a “Dynamic Stiffness Measurement” (DSM) facility that permits measurement of storage modulus and loss modulus at frequent intervals during an indentation test. The results were quite scattered, especially those for the loss modulus, and methods of processing the data to derive meaningful results were examined and are discussed. The storage modulus measurements were found to give the same stiffness ranking as the monotonic load‐displacement data when comparing indentations on the same material. Some correlation was found between the storage modulus and fractional crystallinity. An averaging procedure was developed for the loss modulus values that appeared to give a consistent assessment of the dissipation properties of the different materials. Analysis of the monotonic component of the load‐displacement data indicated that the nature of the deformation changed from mainly elastic/viscoelastic to mainly viscoelastic/plastic during the course of the indentation tests.

A Highly Effective Cobalt Catalyst for Olefin Aziridination with Azides: Hydrogen Bonding Guided Catalyst Design (2008)

[Co(P1)], which was designed on the basis of potential hydrogen-bonding interactions in the metal-nitrene intermediate, is a highly active aziridination catalyst with azides. [Co(P1)] can effectively aziridinate various aromatic olefins with arylsulfonyl azides under mild conditions, forming sulfonylated aziridines in excellent yields. The Co-based system enjoys several attributes associated with the relatively low cost of cobalt and the wide accessibility of arylsulfonyl azides. Furthermore, it generates stable dinitrogen as the only byproduct.
[The relationship of eosinophil viability enhancing activity in sputum and clinical symptoms in asthma]. (1996)

We studied the correlation of eosinophil viability enhancing activity (EVEA) in sputum from asthmatic children and clinical symptoms. Sputum from asthmatic children and equal volume of saline were mixed with a Vortex mixer and centrifuged at 40000 G. Clear supernatants were obtained and filtered with 0.22 micron membrane filter. Periphral blood eosinophils purified by Percoll density gradient centrifugation and CD16 negative selection/ immunomagnetic beads technique were incubated with sputum extract for 4 days. Eosinophil viability was examined by staining the cells with fluorescen diacetate and propidium iodide and expressed as eosinophil viability enhancing activity (EVEA). Eosinophil cationic protein (ECP) concentrations in sputum were also measured by a radioimmunoassay. Correlation between EVEA in sputum and pulmonary functions, attack score, treatment score, or sputum ECP was determined by Spearman correlation test. Sputum EVEA was correlated 1) inversely with pulmonary functions on sampling, 2) with attack score of 2 weeks period before sampling, 3) with treatment score of 1 month to 1 week before and 1 to 2 weeks after sampling, and 4) with sputum ECP in individual cases. Sputum EVEA may serve as a suitable parameter for monitoring airway inflammation in asthma.
Shaping of soliton- into rectangular-pulses using a superstructure fiber Bragg grating (1999)

In this paper we discuss a technique that employs superstructure fiber Bragg gratings for coherent control of short pulses. This is achieved by filtering the incoming spectrum, both in amplitude and phase. Using such a grating we have achieved the reshaping of 2.5 ps soliton pulses with a repetition rate of 10 GHz into 20 ps rectangular pulses.
Validation of a Candidate Deoxynivalenol-Inactivating UDP-Glucosyltransferase from Barley by Heterologous Expression in Yeast (2010)

Resistance to the virulence factor deoxynivalenol (DON) due to formation of DON-3-O-glucoside (D3G) is considered to be an important component of resistance against Fusarium spp. which produce this toxin. Multiple candidate UDP-glycosyltransferase (UGT) genes from different crop plants that are either induced by Fusarium spp. or differentially expressed in cultivars varying in Fusarium disease resistance have been described. However, UGT are encoded by a very large gene family in plants. The study of candidate plant UGT is highly warranted because of the potential relevance for developing Fusarium-spp.-resistant crops. We tested Arabidopsis thaliana genes closely related to a previously identified DON-glucosyltransferase gene by heterologous expression in yeast and showed that gene products with very high sequence similarity can have pronounced differences in detoxification capabilities. We also tested four candidate barley glucosyltransferases, which are highly DON inducible. Upon heterologous expression of full-length cDNAs, only one gene, HvUGT13248, conferred DON resistance. The conjugate D3G accumulated in the supernatant of DON-treated yeast transformants. We also present evidence that the product of the TaUGT3 gene recently proposed to encode a DON-detoxification enzyme of wheat does not protect yeast against DON.
Expression of a Male-Specific Factor on Various Stages of Preimplantation Bovine Embryos1 (1987)

Four-cell to blastocyst stage bovine embryos were collected from superovulated donors and cultured for 90 min in Ham's F-10 medium (HF-10) containing 10% (V/V) absorbed anti-histocompatibility (H)-Y antiserum. Embryos were then washed 3 times and placed in HF-10 supplemented with 10% (V/V) fluorescein isothiocynate (FITC)-conjugated goat anti-mouse gamma globulin. After an additional wash, embryos were placed in fresh drops of HF-10, individually evaluated at 200 X magnification, and classified as either fluorescent (H-Y-positive) or nonfluorescent (H-Y-negative). Embryos were then placed in drops of HF-10 containing 14% vinblastin and cultured for 4-6 h. Embryos were coded and individually karotyped, and the sex chromosomes were identified. H-Y antigen was detected as early as the eight-cell stage, but not at the four-cell stage. Seventy-nine percent of fluorescent embryos and 89% of nonfluorescent embryos were XY and XX, respectively. Another experiment was carried out in which H-Y antigen was detected on intact inner cell masses (ICM) isolated by immunosurgery from expanded blastocysts that also had been assayed for H-Y antigen. Eighty-eight and 92%, respectively, of ICM classified as fluorescent or nonfluorescent had been scored the same as intact blastocysts. It is concluded from these data that H-Y antigen can be detected on eight-cell to blastocyst stage bovine embryos. There appears to be a localization of detectable antigen in the area of the ICM at the expanded blastocyst stage. Detection of H-Y antigen is an effective, noninvasive method for identification of the sex of preimplantation bovine embryos.
Effects of Chlorpromazine on the Activities of Antioxidant Enzymes and Lipid Peroxidation in the Various Regions of Aging Rat Brain (1984)

In this work, the effect of chronic intraperitoneal administration of chlorpromazine (5 and 10 mg/kg) on the antioxidant enzymes superoxide dismutase (SOD), catalase (CA), glutathione reductase (GR), and glutathione peroxidase (GP); lipid peroxidation; and lipofuscin accumulation in the brains of rats ages 6, 9, and 12 months was studied. Chlorpromazine increased the activities of SOD, GR, and GP in particulate fraction from cerebrum, cerebellum, and brain stem in a dose-dependent manner. While GR and SOD associated with soluble fraction increased, GP associated with soluble fraction was not affected. CA did not change after chlorpromazine administration in any regions of the brain of rats from all age groups. Chlorpromazine, thus, had a somewhat different action on antioxidant enzymes in different subcellular fractions. Chlorpromazine inhibited lipid peroxidation, both in vivo and in vitro, and it also inhibited accumulation of lipid peroxidation fluorescent products (lipofuscin), which was studied histochemically and biochemically as well. The data indicate that chlorpromazine inhibition of lipid peroxidation and of accumulation of lipofuscin can result from elevation of the activity of brain antioxidant enzymes.

Pole-changing permanent-magnet machines (2002)

Electric drives in which discrete speed control is required are today equipped exclusively with squirrel-cage induction motors, due to the property of the squirrel cage to always have the same number of poles as the stator winding. Conventional permanent-magnet (PM) machines have a constant number of poles and can be operated from a constant frequency source only at one speed. If a PM machine is built after the principles of memory motors, one can change its number of poles as simply as in a squirrel-cage machine. In this paper, the principles of. operation of a pole-changing memory motor are described, and its measured performance is presented and discussed.

Penetration and screening of perpendicularly launched electromagnetic waves through bounded supercritical plasma confined in multicusp magnetic field (2011)

The question of electromagnetic wave penetration and screening by a bounded supercritical (ωp&gt;ω with ωp and ω being the electron-plasma and wave frequencies, respectively) plasma confined in a minimum B multicusp field, for waves launched in the k⊥Bo mode, is addressed through experiments and numerical simulations. The scale length of radial plasma nonuniformity (|ne/(∂ne/∂r)|) and magnetostatic field (Bo) inhomogeneity (|Bo/(∂Bo/∂r)|) are much smaller than the free space (λo) and guided wavelengths (λg). Contrary to predictions of plane wave dispersion theory and the Clemow–Mullaly–Allis (CMA) diagram, for a bounded plasma a finite propagation occurs through the central plasma regions where αp2=ωp2/ω2≥1 and βc2=ωce2/ω2⪡1(∼10−4), with ωce being the electron cyclotron frequency. Wave screening, as predicted by the plane wave model, does not remain valid due to phase mixing and superposition of reflected waves from the conducting boundary, leading to the formation of electromagnetic standing wave modes. The waves are found to satisfy a modified upper hybrid resonance (UHR) relation in the minimum B field and are damped at the local electron cyclotron resonance (ECR) location.
Differential Expression of the Translocated and the Untranslocated c- <i>myc</i> Oncogene in Burkitt Lymphoma (1983)

Burkitt lymphoma cells carrying either a rearranged or unrearranged c-myc oncogene were examined with the use of probes from the 5' exon and for the second and third exon of the oncogene. The results indicate that the normal c-myc gene on chromosome 8 and the 5' noncoding and 3' coding segments of the c-myc oncogene separated by the chromosomal translocation are under different transcriptional control in the lymphoma cells. Burkitt lymphoma cells carrying a translocated but unrearranged c-myc oncogene express normal c-myc transcripts. In contrast, lymphoma cells carrying a c-myc gene rearranged head to head with the immunoglobulin constant mu region gene express c-myc transcripts lacking the normal untranslated leader.
Qué es la energía negativa (2000)

The reconstitution time of IgG, IgA and IgM was different in MM patients after auto-HSCT. IgG recovered first, then IgM, and IgM the last. The incidence of infection was negatively correlated with IgA and IgG. With the recovery of IgG and IgA, the incidence of infection was decreased accordingly.
The Effect of Adenosine A2A and A2B Antagonists on Tracheal Responsiveness, Serum Levels of Cytokines and Lung Inflammation in Guinea Pig Model of Asthma (2013)

These results showed a preventive effect of A2B antagonist (MRS1706) on tracheal responsiveness to methacholine and OA, total and differential cell count in bronchoalveolar lavage, blood cytokines and pathological changes. Administration of ZM241385, selective A2A antagonist, deteriorated the induction effect of ovalbumin.
Quantitative Analysis of Human Internal Limiting Membrane Extracted from Patients with Macular Holes (2010)

We report the study of the morphology, topography, and adhesion properties of internal limiting membrane (ILM) from patients with macular holes. The quantitative analysis of human ILM could provide essential information toward the improvement of existing surgical instruments for more efficient and safer surgical removal of ILM. Imaging in air revealed the presence of globular structures in most of the samples analyzed which were coupled with fibrillar structures in some of the samples. Modification of silicon nitride AFM tips with oppositely charged functional groups showed changes in adhesion force at the membrane-tip interface. Defining the surface characteristics of the human ILM is an initial step in the development of improved surgical tools that may allow nontraumatic stripping of ILM during surgery.
Notice of Violation of IEEE Publication Principles<BR>9.953-12.5GHz 0.13&#x003BC;m CMOS LC VCO using a high resolution calibration and a constant gain varactor (2005)

The phase noise was reduced by using a high quality factor bond wire inductor in conjunction with a high resolution calibration network that brings the oscillating frequency to within 0.1% of the target value, reducing thus the oscillator gain below 110MHz/V. A low gain ripple varactor was realized with multiple parallel connected accumulation MOS capacitors having the bias voltages offset such that their peak gain points are uniformly distributed over the control voltage range. The supply pushing was minimized by cancelling the gate capacitance positive voltage coefficient with the negative coefficient of an appropriately sized drain diffusion capacitance. A dual regulator architecture was used to ensure the low noise and high PSRR requirements.
Performance of a dual headed SPECT system modified for coincidence detection (2002)

A NIM/CAMAC/Macintosh data acquisition system was developed to collect/sup /spl plusmn//X, /sup /spl plusmn//Y, and E information from a GE Maxxus SPECT system. A high impedance signal pick-off circuit was used so the data could be collected without disturbing normal operation of the camera. The measured coincidence timing resolution for the system is 8 msec FWHM. The energy resolutions for the detector heads are /spl sim/7.5% (using pulse clipping), at 511 keV. The system sensitivity is 70 cps//spl mu/Ci for a point source centered in the field of view (450-575 keV energy window, 62.6 cm detector spacing). The intrinsic spatial resolution of the detector heads are /spl sim/3.7 mm FWHM in the focal plane using linear tomography. Linear tomography image reconstruction and a volume image reconstruction based on the Kinahan-Rogers approach have been implemented. Images of a line source phantom, the Data Spectrum torso phantom, and the 3D Hoffman brain phantom.
Recent progress in autophagic lysosome reformation (2017)

Autophagic lysosome reformation (ALR) is the terminal step of autophagy and is essential for maintaining lysosome homeostasis during autophagy. During ALR, tubules are extruded from autolysosomes, and small vesicles named proto-lysosomes, which are composed of lysosomal membrane components, are generated from these tubules. Eventually, proto-lysosomes mature into functional lysosomes. In this review, we will summarize recent progress in understanding the regulation, mechanisms and physiological functions of ALR.
Verification of a non-contact vital sign monitoring system using an infant simulator (2009)

In this paper, experimental result using a 5.8 GHz Doppler radar to monitor the variations of vital signs of an infant simulator under different medical conditions is presented. The infant simulator can mimic cardiovascular derangements seen in critically ill infants. The result demonstrates the system is capable of tracking a majority of the changes in heart rate and respiratory rate. Analysis suggests possible techniques for further improvement, such as direct coupling circuit, carrier frequency tuning and spectral analysis.
Multi-Layer Combinatorial Fusion Using Cognitive Diversity (2020)

Multiple scoring systems (including rank and score functions; MSS) have been widely used in multiple regression, intelligent biometric systems, multiple artificial neural nets, combining pattern classifiers, ensemble methods, machine learning and artificial intelligence (AI), data and information fusion, preference ranking, and deep learning. Combining MSS has achieved numerous successful results in a variety of domain applications. However, the reasons why this happens remains an active area of investigation. Combinatorial fusion analysis (CFA) combines MSS using the rank-score characteristic (RSC) function and cognitive diversity (CD). The RSC function was proposed to characterise the predictive behaviour of a scoring system. It was subsequently used to define the notion of “cognitive diversity”, which measures the dissimilarity in the representation of information between two scoring systems. In this article, we first examine characterizations of and diversity between scoring systems. Then, we review combinatorial fusion analysis with a variety of domain applications, including biometric systems in cognitive neuroscience, and joint decision making with visual cognitive systems. Finally, we demonstrate that multi-layer combinatorial fusion (MCF) on the Kemeny rank space is a viable machine learning and AI framework for preference ranking and reinforcement learning. This work provides a scientific foundation and technological insights for the use of Combinatorial Fusion in ensemble methods, data and information fusion, preference ranking, and deep reinforcement learning with applications to a variety of domains in data science and informatics for secure and sustainable societies.
Survival of Animal Tissue Cells in Primary Culture in the Absence of Serum (1973)

The ability of cells from tissues of several species of animals to survive in primary culture without serum was tested. Of the species tested, cells from the kidneys of Macaca mulatta (rhesus) and Cercopithecus aethiops (vervet) monkeys and chicken embryo cells not only survived under these conditions, but indeed developed into confluent monolayer cultures. The addition of either serum or its globulin or albumin fraction enhanced the development of cell monolayers and permitted those cells unable to survive in the absence of serum to do so. Certain specific protein trypsin-inhibitors not of serum origin were unable to provide conditions necessary for cell survival or growth when used in place of serum proteins.
Synthesis of Itaconic Acid Ester Analogues via Self-Aldol Condensation of Ethyl Pyruvate Catalyzed by Hafnium BEA Zeolites (2016)

Lewis acidic zeolites are used to synthesize unsaturated dicarboxylic acid esters via aldol condensation of keto esters. Hafnium-containing BEA (Hf-BEA) zeolites catalyze the condensation of ethyl pyruvate into diethyl 2-methyl-4-oxopent-2-enedioate and diethyl 2-methylene-4-oxopentanedioate (an itaconic acid ester analogue) with a selectivity of ca. 80% at ca. 60% conversion in a packed-bed reactor. The catalyst is stable for 132 h on stream, reaching a turnover number of 5110 molEP molHf–1. Analysis of the dynamic behavior of Hf-BEA under flow conditions and studies with Na-exchanged zeolites suggest that Hf(IV) open sites possess dual functionality for Lewis and Brønsted acid catalysis.
Design and performance evaluation of a high throughput Ethernet/FDDI interconnect (2002)

A filtering algorithm, called MFA, that sets the minimum power requirements for a bridge connecting an Ethernet LAN to a fiber-distributed data interface (FDDI) backbone is introduced. With current technology, however, even MFA cannot be implemented in software at an acceptable speed. A hardware solution based on the use of content-addressable memories (CAMs) is described, and a comparison is made between hardware and software solutions through analytical and simulation models.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
