Verdazyl‐Mediated Polymerization of Styrene (2007)

Attempted controlled polymerizations of styrene, conducted in the presence of either 1,3,5-triphenyl-6-oxoverdazyl or 1,5-dimethyl-3-phenyl-6-oxoverdazyl radicals initiated with benzoyl peroxide or 1,1′-azobis(cyclohexanecarbonitrile) were universally unsuccessful regardless of the reaction temperature and the initiator/ verdazyl molar ratio. No improvement was observed using a verdazyl-terminated styrene initiator adduct prepared by an exchange reaction between a styrene-TEMPO alkoxyamine and a 1,3,5-triphenyl-6-oxoverdazyl radical. However, controlled polymerizations of styrene were achieved at 125 °C using a styrene-verdazyl adduct containing the 1,5-dimethyl-3-phenyl-6-oxoverdazyl radical. Polydispersity indexes remained low throughout the polymerizations and plots of number average molecular weight (M̄n) versus time were linear. However, the actual M̄n values were considerably lower than theoretical, an unexpected result that is under investigation.
A high performance BiCMOS process featuring 40 GHz/21 ps (1992)

A high performance BiCMOS process is presented which features 40 GHz cutoff frequency, 21 ps gate delay and 20 GHz divider circuits for the bipolar part together with 0.6 mu m CMOS. Deep trench isolation is used for low collector to substrate capacitances and high packing density. Concepts to decouple the bipolar from the CMOS building blocks for an uncompromised optimization of both device types are proposed and discussed.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>

Use of ChromID Extended-Spectrum β-Lactamase Medium for Detecting Carbapenemase-Producing <i>Enterobacteriaceae</i> (2010)

ChromID extended-spectrum beta-lactamase (ESBL) culture medium is routinely used for screening ESBL producers. This medium was tested for detecting carbapenemase-producing Enterobacteriaceae isolates from a collection of reference strains and compared to the CHROMagar KPC culture medium previously evaluated for detecting KPC-producing isolates. Producers of IMP-, VIM-, and KPC-type carbapenemases with high levels of resistance to cephalosporins and to carbapenems were detected at 1x10(1) CFU/ml. The OXA-48 producers were not detected on ChromID ESBL medium unless coexpressing ESBLs, whereas carbapenemase-producing isolates with MICs of <4 microg/ml were not detected on CHROMagar KPC medium.
Petri nets and industrial applications: A tutorial (1994)

Petri nets, as a graphical and mathematical tool, provide a uniform environment for modelling, formal analysis, and design of discrete event systems. The main objective of this paper is to introduce the fundamental concepts of Petri nets to researchers and practitioners, both from academia and industry, who are involved in the work in the areas of modelling and analysis of industrial types of systems, as well as those who may potentially be involved in these areas. The paper begins with an overview of applications of Petri nets, mostly industrial ones. Then, it proceeds with a description of Petri nets, properties, and analysis methods. The discussion of properties is put in the context of industrial applications. The analysis methods are illustrated using an example of a simple robotic assembly system. The performance analysis, using Petri nets, is discussed for deterministic and stochastic Petri nets. The presented techniques are illustrated by examples representing simple production systems. In addition, the paper introduces high-level Petri nets, fuzzy Petri nets, and temporal Petri nets. This is done in the context of application prospects. The paper also briefly discusses some of the reasons restricting the use of Petri nets, mostly, to academic institutions.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Direct RF Subsampling Receivers Enabling Impulse-Based UWB Signals for Breast Cancer Detection (2014)

The implementation of a Direct RF subsampling receiver in CMOS is presented for the application of breast cancer detection using impulse-based ultrawideband (UWB) signals. Such a receiver inherently benefits from CMOS scaling since its speed-accuracy tradeoff depends only on technological process parameters. With a proper choice of antenna matching media, the current signal processing requested resolution could be translated into feasible hardware specifications. The track-and-hold (T/H) circuit is analyzed and implemented in a 40-nm chip since this block must cope with the full RF BW. An effective resolution BW of 5.5 GHz was measured with an accuracy of 6 b for rail-to-rail input signals. Second, a two-stage Miller compensated fully differential difference amplifier is discussed with low input parasitics (10 fF) to enable measurements without limiting the performance.
Broadband, Ultra-sparse Array Processing for Low Complexity Multibeam Sonar Imaging (2007)

Despite the rapidly reducing cost of DSP technology and other digital electronics, the cost of multibeam sonar systems remains very high. This is largely due to large receiving arrays (typically 100-200 channels) each with transducer, amplifier/filters and ADC. The power consumption of such complex systems is also a problem for battery operated systems such as AUVs. This paper describes novel work to investigate if such imaging can be achieved with an "ultra-sparse array" of no more than 4 elements, exploiting the broad bandwidth provided by modern piezo-composite transducers which can far exceed range resolution requirements.
Characterization of Cationic Liposome-Mediated Gene Transfer <i>In Vivo</i> by Intravenous Administration (1997)

Physicochemical properties of the cationic liposomes, including structure of the cationic lipid-to-DNA ratio, liposome particle size, and inclusion of the helper lipids, were studied for their effect on the level, site, and duration time of gene expression in vivo by intravenous administration. Using a cytomegalovirus (CMV)-driven gene expression system containing either the luciferase or green fluorescence protein gene as a reporter and two cationic lipids [N-(2,3-dioleoyloxy)propyl-N,N,N-trimethylammonium chloride (DOTMA) and 1,2-dioleoyloxy-3-trimethylammonium propane (DOTAP)], we demonstrated in vivo by a single intravenous injection of DNA/liposome complexes into mice, that cationic liposomes are capable of transfecting cells in organs such as the lung, heart, liver, spleen, and kidney. Transfection efficiency is determined mainly by the structure of the cationic lipid and the ratio of cationic lipid to DNA. Although the presence of cholesterol in DOTAP liposomes did not affect transfection activity, inclusion of dioleoylphosphatidylethanolamine (DOPE) into either DOTAP or DOTMA liposomes significantly decreases liposome transfection activity in vivo. Results form time course show that gene expression in different organs is transient, with a peak level between 4 and 24 hr, dropping to less than 1% of the peak level by day 4. Experiments with repeated injections showed that the peak level of gene expression could be regained by subsequent injection.
Laser focusing and defocusing via anomalous dispersion and density inhomogeneity in Tl vapour (1991)

An optical effect showing focusing and defocusing of a dye laser beam near the atomic resonance of the Tl*6p2P3/2-7s2S1/2 transition in Tl vapour produced by photodissociation is reported. The experimental investigation of the effect as a function of detuning, vapour number density, dissociation laser energy and dye laser energy is presented. The effect is attributed to distortion of the dye laser wavefront by anomalous dispersion near the resonance and the inhomogeneous number density of Tl atomic vapour produced by an inhomogeneous intensity distribution of the dissociation laser.
On Heuristic Randomization and Reuse as an Enabler of Domain Transference (2015)

The solution of NP-hard problems requires the use of one or more explicit or implicit heuristics as a practical measure. Quantum computers promise to make this practical for O (2n) problems or less, but have yet to deliver a solution to a single NP-hard problem. The question addressed by this paper is whether domain transference and reuse of problem-solving knowledge can be mediated through the reuse of heuristics, and, if so, the extent to which such transference may occur in the solution of NP-hard problems. Neural networks have zero domain transference on account of their inability to represent modus ponens. Similarly, CBR, deep learning, EP, GAs, SVMs, the predicate calculus, learning via conventional expert systems, and all other machine learning technologies are unable to theoretically or practically mediate domain transference because they don't respect randomization as the core underpinning technology. The paper offers a constructive proof of the unbounded density of knowledge in support of the Semantic Randomization Theorem (SRT). It details this result and its potential impact on the machine learning community.
A Model for the Mechanism of Oil Recovery from the Porous Matrix Due to Water Invasion in Fractured Reservoirs (1958)

Published in Petroleum Transactions, AIME, Volume 213, 1958, pages 17–19. Introduction The first step in a quantitative analysis of the mechanism of oil displacement by water in a fractured reservoir is usually conceded to be the solution of the differential equation describing the saturation distribution of two immiscible fluids flowing in a porous medium, where the capillary pressure is taken into account. In such a system the production mechanism may consist of displacement of oil both by the flow of water due to natural or artificially imposed pressure gradients and by imbibition, which implies a flow of water not due to external pressure gradients. Owing to the presence of the two oil displacement mechanisms, the mathematical model given by the differential equation intended to describe the system may not properly represent the behavior of the physical system. In fact, in the reservoir the rate of water advance may be very slow, and in the case of a fractured reservoir with a great number of large fractures, the pressure difference determining the flow of water through the matrix may be much less than 1 lb/psi over lengths of a few feet. In such a case, imbibition (the exchange between oil in the matrix and water in the fractures resulting from capillary forces) may become, with time, a significant element of the production mechanism. It occurred to the authors, however, that without going into a physical analysis of the process of production, it might be possible by means of simple abstract reasoning to throw some light on the variation of recovery with time under conditions occurring in a highly fractured oil reservoir with rising water table. The object of this paper is to present both the reasoning and its application to a reservoir of the highly fractured type. Specifically, the analysis given here was undertaken to try to explain the increase of recovery (as defined later) with time as observed in this reservoir, without having to assume unlikely variations in the reservoir parameters with depth. This attempt has been successful as will become clear upon comparison of the computed recoveries with the actual field data.

Alterations in tumor development in vivo mediated by expression of wild type or mutant p53 proteins. (1991)

To study the mechanism of p53 involvement in malignant transformation, we compared the tumor development patterns induced by a parental p53 nonproducer pre-B cell line with those by cell lines generated from this parental cell line following transfection of either wild type or mutant p53. It was found that whereas mutant p53 facilitated tumor development, expression of wild type p53 restrained tumor development. Cell lines expressing the wild type p53 induced the development of faster regressing tumors than the parental cell line. The parental p53 nonproducer and the wild type p53 producer regressor tumors underwent in vivo cell differentiation, manifested as IgG production. Mutant p53, producer cell lines, on the other hand, failed to show any immunoglobulin synthesis and gave rise to highly proliferative lethal tumors. Our results support the conclusion that these pre-B cells develop regressor tumors because they have undergone differentiation. Whereas the wild type p53 facilitates this differentiation, mutant p53 cells block it. We suggest that, in addition to inactivating the growth-suppressive activity of wild type p53, the expression of mutant p53 facilitates malignant transformation.
Electrical Conduction and Phase Transition of Copper Sulfides (1973)

Electrical conductivity measurements have been made on copper sulfide crystals of compositions ranging from Cu1.8S to Cu2.0S and indium-doped Cu1.8S in the temperature region between 20°C and 220°C. Conductivity of Cu2-xS varied from 0.07 ohm-1cm-1 to 2400 ohm-1cm-1 as the deviation from stoichiometry increased from x=0 to x=0.2. It was found that Cu1.8S (digenite) and Cu1.96S (djurleite) undergo phase transitions at 90°C and at 93°C respectively. The transition temperature of Cu2S (chalcocite) increased from 98°C to 108°C as conductivity decreased from 52 ohm-1cm-1 to 0.07 ohm-1cm-1. An analysis of mixed conduction at β phase of low conductivity copper sulfide has shown that ionic conductivity is independent of the composition or the number of impurity cations in this material, and exhibits a temperature dependence with activation energy of 0.24 eV. Finally it is emphasized, after the discussion of the relation between electrical properties and crystal structure of copper sulfides, that the composition and crystalline phase are well characterized by the electrical conductivity in these materials.
A New Look at Posturographic Analysis in the Clinical Context: Sway-Density versus Other Parameterization Techniques (2002)

In order to identify useful guidelines for the clinical practitioner as regards the use of static posturographic analysis, we collected a set of posturograms from 3 groups of participants (normal participants, Parkinsonian patients, and osteo-porotic patients), according to the Romberg test. From each posturogram, we extracted global parameters (in the time domain and frequency domain) and structural parameters (based on diffusion plots and sway-density plots), with a total of 38 parameters. The discriminative power of each parameter was evaluated by means of statistical analysis in relation to the condition effect (open vs. closed eyes) and the pathology effect (normal participants vs. patients). The initial set of 38 parameters was reduced to 24 by identifying clear redundancies, and then to 18 by eliminating the parameters that did not pass the condition effect with normal participants. These parameters were analyzed for reliability and discriminative power in the general framework of a biomechanic model of postural stabilization. At the end of this analysis, we suggested that a set of 4 parameters is particularly valuable in the clinical practice: 2 global parameters (sway-path and frequency band of the posturogram) and 2 structural parameters (mean value of peaks and mean inter-peak distance in the sway-density plots).

Perspectives on Semantics of the Place from Online Resources (2009)

We present a methodology for extraction of semantic indexes related to a given geo-referenced place. These lists of words correspond to the concepts that should be semantically related to that place, according to a number of perspectives. Each perspective is provided by a different online resource, namely upcoming.org, Flickr, Wikipedia or open Web search (using Yahoo! search engine). We describe the process by which those lists are obtained, present experimental results and discuss the strengths and weaknesses of the methodology and of each perspective.
The dynamics of the imprinted H19 gene expression in the mouse model of bladder carcinoma induced by N-butyl-N-(4-hydroxybutyl)nitrosamine (1998)

The imprinted H19 gene product is an oncofetal RNA molecule in humans. It is expressed in fetal bladder, down-regulated postnatally and is re-expressed in human bladder carcinoma. This study was designed to investigate the dynamics of the expression of H19 in the mouse bladder carcinoma induced by N-butyl-N-(4-hydroxybutyl)nitrosamine (BBN) and its relation to stages of neoplastic transformation. BBN was administered to mice in the drinking water for 26-28 weeks. The bladders were removed at 5-10 week intervals for histopathological examination and for in situ hybridization for H19 RNA, using a 35S-labeled probe. Following BBN administration expression of H19 first appeared after 5 weeks in the lamina propria adjacent to the basement membrane, concomitant with mucosal hyperplasia. At 11 weeks focal expression was noted in epithelial cells. Invasive carcinomas, of the transitional and squamous sub-types, were seen after 20 weeks and more of BBN administration. At this stage H19 expression was observed in scattered tumor cells, in the connective tissue stroma of the tumor and in the lamina propria underlying the remaining hyperplastic/dysplastic mucosa. Abundant expression of H19 was evident in fetal bladder but was absent in normal adult bladder. We conclude that, similar to humans, the H19 gene product is an oncofetal RNA molecule in the experimental mouse model of bladder carcinoma. In this model H19 is expressed in the connective tissue of the lamina propria prior to its expression in epithelial cells, concurrent with preneoplastic changes in the transitional epithelium of the bladder.

Developmental Biochemistry of Cotton Seed Embryogenesis and Germination (1978)

The enzymic basis for the flow of nitrogen from arginine to asparagine during the first 3 days of germination has been measured in extracts from cotton (Gossypium hirsutum) cotyledons. Evidence that asparagine synthetase regulates asparagine accumulation in germination (for transport to the axis) is presented. Further, evidence that the bulk of the nitrogen passed from one generation to the next in dicots is through an asparagine cycle involving the following sequence asparagine --> arginine --> storage protein --> arginine --> asparagine is discussed.
