Ways to improve outcome after cardiopulmonary resuscitation. How to monitor patients, correct dysrhythmias. (1992)

Noninvasive monitoring techniques for assessing circulation during CPR include thoracic electrical bioimpedance and measurement of end-tidal carbon dioxide. Many dysrhythmias can be corrected with portable devices, such as automatic external defibrillation pacers, or with automatic implantable cardioverter-defibrillators or external transcutaneous cardiac pacers. Bradycardia is treated, however, only if it is accompanied by hemodynamically significant hypotension or ventricular ectopy. Adenosine may be preferable to verapamil for the management of paroxysmal supraventricular tachycardia. Three consecutive energy discharges are now recommended for the management of ventricular fibrillation.

Power generation from conductive droplet sliding on electret film (2012)

Generating electrical power from low frequency vibration to power portable devices is a challenge that potentially can be met by nonresonant electrostatic energy harvesters. We propose a generator employing a conductive droplet sliding on a microfabricated electret film which is sputtered onto an interdigital electrode and charged already during deposition. Droplet motion causes a capacitance variation that is used to generate electric power. A prototype of the fluidic energy harvester demonstrated a peak output power at 0.18 µW with a single droplet having a diameter of 1.2 mm and sliding on a 2 -µm thick electret film.
Flexible Electrically Conductive Nanocomposite Membrane Based on Bacterial Cellulose and Polyaniline (2011)

The novel conductive polyaniline/bacterial cellulose (PANI/BC) nanocomposite membranes have been synthesized in situ by oxidative polymerization of aniline with ammonium persulfate as an oxidant and BC as a template. The resulting PANI-coated BC nanofibrils formed a uniform and flexible membrane. It was found that the PANI nanoparticles deposited on the surface of BC connected to form a continuous nanosheath by taking along the BC template, which greatly increases the thermal stability of BC. The content of PANI and the electrical conductivity of composites increased with increasing reaction time from 30 to 90 min, while the conductivity decreased because of the aggregation of PANI particles by further prolonging the reaction time. In addition, the acids remarkably improve the accessibility and reactivity of the hydroxyl groups of BC. The results indicate that the composites exhibit excellent electrical conductivity (the highest value was 5.0 × 10(-2) S/cm) and good mechanical properties (Young's modulus was 5.6 GPa and tensile strength was 95.7 MPa). Moreover, the electrical conductivity of the membrane is sensitive to the strain. This work provides a straightforward method to prepare flexible films with high conductivity and good mechanical properties, which could be applied in sensors, flexible electrodes, and flexible displays. It also opens a new field of potential applications of BC materials.
Dihydroceramide Biology (1997)

This study utilized fluorescent analogs to characterize the intracellular transport and metabolism of dihydroceramide (DH-Cer), an intermediate in de novo sphingolipid biosynthesis. When 6-[N-(7-nitro-2,1,3-benzoxadiazol-4-yl)amino]hexanoyl-DH-Cer (C6-NBD-DH-Cer) was incubated with HT29, NRK, BHK, or HL-60 cells, it was efficiently converted to dihydrosphingomyelin and dihydroglucosylceramide, and a number of other sphingolipids, with the nature of the products depending on the cell line. In addition, complex sphingolipids were formed that contained a desaturated (sphingosine) backbone, indicating that DH-Cer (and/or its metabolites) were substrates for the desaturase(s) that introduce the 4,5-trans double bond. Based on the kinetics and inhibitor studies, double bond addition did not appear to occur with the complex sphingolipids directly, but rather, during turnover and resynthesis. The conversion of C6-NBD-DH-Cer to more complex sphingolipids was highly stereoselective for the natural D,erythro isomer of C6-NBD-DH-Cer. Interestingly, the stereochemistry of the sphingoid base backbone also affected the localization of fluorescent sphingolipids: the D,erythro species appeared in the Golgi apparatus, whereas other stereo-isomers accumulated in the endoplasmic reticulum. In addition to C6-NBD-Cer and C6-NBD-DH-Cer, C6-NBD-4-D-hydroxy-DH-Cer gave rise to formation of complex sphingolipids and localized at the Golgi apparatus. These studies indicate that dihydroceramide is used as the initial backbone of complex (glyco)sphingolipids, perhaps to avoid build up of ceramide as an intermediate since this is such a potent bioactive compound. The stereoselectivity in transport and metabolism suggests that trafficking of ceramide is protein-directed rather than simply a consequence of vesicular membrane flow.

Analysis of terpene variation in leaves and fruits of <i>Citrus unshiu</i> Marc. during ontogenesis (1989)

Abstract The dynamics of accumulation of mono‐and sesquiterpenes in leaves and fruits of a mandarin ( Citrus unshiu Marc.) during ontogenesis was studied. Limonene, linalol, p ‐cymene, β‐elemene are found to accumulate intensively in fruits prior to ripening. From that time till the physiological maturity of fruits, the biosynthesis of γ‐terpinene, β‐elemene and especially that of limonene increases, while the content of linalol, β‐caryophyllene, p‐cymene and α‐terpineol decreases. From the beginning of time of blossoming until the commencement of fruit ripening, the content of γ‐terpinene and p ‐cymene varies essentially in leaves. From October the content of mono and sesquiterpenoids decreases sharply and remains practically unchanged during the forced state of rest.
Docosahexaenoic acid-enriched egg consumption induces accretion of arachidonic acid in erythrocytes of elderly patients (2004)

Many studies in humans volunteers have shown that dietary docosahexaenoic acid (DHA) supplied as triacylglycerol can increase DHA levels in blood lipids but often strongly decreases those of arachidonic acid (AA). The aim of the present study was to determine the effect of dietary supplementation with egg-yolk powder enriched in DHA, corresponding to the French recommended dietary allowance for DHA, on the blood lipid status of an elderly population. Institutionalised elderly individuals aged between 63 and 93 years consumed an egg product enriched in DHA (150 mg/d) once daily for 9 months. Plasma lipids and the fatty acid composition of erythrocyte membranes were determined every 3 months. The supplementation induced an increase in the PUFA content of plasma and erythrocyte membranes which was +14.5 and +25.3 %, respectively, at 9 months. This effect was mainly due to the level of DHA and, unexpectedly, to that of AA which continuously increased. This increase in AA was the result of an increased dietary intake (+50 mg/d) and very probably of an increased biosynthesis as demonstrated by the behaviour of di-homo-gamma-linolenic acid. The supplementation resulted in a blood PUFA status comparable with that of young healthy controls. The data are consistent with a strong regulatory action of the dietary treatment on the subjects' lipid metabolism.

Methylphosphate cap structure increases the stability of 7SK, B2 and U6 small RNAs in<i>Xenopus</i>oocytes (1993)

We studied the role of the methylphosphate cap structure in the stability and nucleocytoplasmic transport by microinjecting U6, 7SK and B2 RNAs into the Xenopus oocytes. In every case, the methylphosphate capped RNAs were 3 to 9 times more stable than the uncapped RNAs. When a methylphosphate cap structure was placed on human H1 RNA which is normally not capped, its stability was improved 2-7 fold. These data show that the methylphosphate cap enhances the stability of 7SK, B2, H1 and U6 RNAs. The methylphosphate-capped 7SK RNA was transported into the nucleus from cytoplasm, but remained in the nucleus when injected into the nucleus; in this respect, 7SK RNA exhibited properties previously shown for U6 RNA. Both U6 and 7SK RNAs with ppp on their 5' ends were transported from cytoplasm to the nucleus suggesting that the methylphosphate cap structure is not required for transport of these RNAs across the nuclear membrane.
Multi-channel composite spoof surface plasmon polaritons propagating along periodically corrugated metallic thin films (2014)

In this work, we demonstrate that composite spoof surface plasmon polaritons can be excited by coplanar waveguide, which are composed of two different spoof surface plasmon polaritons (SSPPs) modes propagating along a periodically corrugated metallic thin film simultaneously. These two SSPPs correspond to the dominant modes of one-dimensional (1D) periodical hole and groove arrays separately. We have designed and simulated a planar composite plasmonic waveguide in the microwave frequencies, and the simulation results show that the composite plasmonic waveguide can achieve multi-channel signal transmission with good propagation performance. The proposed planar composite plasmonic metamaterial can find potential applications in developing surface wave devices in integrated plasmonic circuits and multi-channel signal transmission systems in the microwave and terahertz frequencies.
The speed-accuracy tradeoff: history, physiology, methodology, and behavior (2014)

There are few behavioral effects as ubiquitous as the speed-accuracy tradeoff (SAT). From insects to rodents to primates, the tendency for decision speed to covary with decision accuracy seems an inescapable property of choice behavior. Recently, the SAT has received renewed interest, as neuroscience approaches begin to uncover its neural underpinnings and computational models are compelled to incorporate it as a necessary benchmark. The present work provides a comprehensive overview of SAT. First, I trace its history as a tractable behavioral phenomenon and the role it has played in shaping mathematical descriptions of the decision process. Second, I present a "users guide" of SAT methodology, including a critical review of common experimental manipulations and analysis techniques and a treatment of the typical behavioral patterns that emerge when SAT is manipulated directly. Finally, I review applications of this methodology in several domains.
College Students' Perceptions of Binge Drinking (2004)

This study was designed to examine college students' perceptions of binge drinking. Participants included 180 college student volunteers who read one of three scenarios portraying a party atmosphere with a college student engaging in a different level of drinking in each scenario. The students completed measures assessing their perceptions of the scenario character's alcohol use, their own alcohol use, problems they have experienced due to alcohol, and their perceptions of their friends' and family's alcohol use. Results showed that, compared to men, women anticipated positive outcomes regardless of alcohol consumption and greater sexual outcomes without alcohol consumption. For both men and women, negative outcomes were perceived as greater with higher amounts of alcohol use. Influences and perceptions of binge drinking by college students are discussed.
<scp>M</scp> arxist Criminology (2013)

Abstract Karl Marx was influential in the “New Criminology” movement of the 1970s and 1980s, although he himself did not provide any specific theories regarding the causes of crime. During this time, there was a surge in research based on critical criminology perspectives. While this theoretical perspective has since fallen out of favor, researchers cannot dismiss the insights it yielded; insights, for example, into the impact that social structure, culturalization, and social class have on the formation of law and the distribution of power within society. Marx thoroughly discussed the marginalization of groups within society, and the way this is accomplished through the creation and enforcement of law and through the creation of specific institutions to further manage the marginalization of these groups. Although not comprehensive, this entry provides a glimpse into the formation of Marxist thought on societal structure and how it was used to critically analyze the structure of American society.
Combination therapy with tazarotene plus a topical corticosteroid for the treatment of plaque psoriasis (1999)

Although tazarotene monotherapy is generally efficacious and well tolerated, studies show that both the efficacy and the tolerability of tazarotene therapy can be further improved when it is used in combination with certain topical corticosteroids. The studies reported here evaluate the usefulness of two potential combination regimens. In one regimen, a corticosteroid is added to tazarotene treatment. In the other regimen, corticosteroid treatment alternates on a daily basis with tazarotene treatment. The results of the first study, which involved 300 patients, showed that additive combination therapy using tazarotene plus a mid- or high-potency topical corticosteroid significantly increased the percentage of plaques achieving treatment success at the end of the treatment period, compared with tazarotene plus placebo (91% and 95% vs. 80%, respectively; P<0.05 for both). Similarly, tazarotene plus a mid- or high-potency topical corticosteroid reduced the incidence of patient withdrawals compared with tazarotene plus placebo (5.5% and 9.6% vs. 13.3%). The results of the second study, which involved 398 patients, showed that a combination regimen that alternates between tazarotene and a high-potency topical corticosteroid treatment each day, significantly increased the treatment success rate compared with regimens using tazarotene alternating with a mid-potency corticosteroid or placebo (75% vs. 55% and 54%, respectively, at the end of the treatment period; P<0.05 for both). In addition, there was a trend towards a lower incidence of treatment-related adverse events as corticosteroid potency increased (from 42% with tazarotene plus placebo to 36%, 32%, and 31% with tazarotene plus the low-, mid-, and high-potency corticosteroid, respectively). Both treatment regimens are potentially useful and offer a rational approach to optimizing the efficacy and tolerability of tazarotene treatment for plaque psoriasis.
Numerical Study of an Electret Filter Composed of an Array of Staggered Parallel Rectangular Split-Type Fibers (2004)

The flow field through a staggered array of parallel, rectangular split-type electret fibers was numerically modeled. The particle trajectory and the collection efficiency were simulated by solving the equation of particle motion, taking into account the effects of diffusion, interception, inertial impaction, and electrostatic forces. The model was validated against results calculated from semiempirical expressions. The model was applied to investigate the role of the inertial impaction and the interception mechanisms in the particle collection by an electret fiber, the particle trajectories under various filtration conditions, the effect of the aspect ratio of the rectangular fiber on the filter penetration, and the distribution of the deposited particles on the surface of the fiber. The simulated results indicate that the inertial impaction and interception mechanisms account for a major portion of neutral particles collected by an electret fiber when the Stokes number is higher than 0.5. For neutral particles, fibers with an aspect ratio of 38/10 have almost the same penetration as fibers with an aspect ratio of 10/38; while for singly charged particles, fibers with an aspect ratio of 38/10 achieve a much lower penetration when the electrophoretic collection mechanism dominates. In addition, it is predicted that a filter composed of fibers with an aspect ratio of 38/10 will result in a lower flow resistance and thus a slower clogging process when the dielectrophoretic collection mechanism dominates.
On sound scattering and attenuation of Albunex® bubbles (1996)

In this paper, the theory of wave scattering by shelled scatterers is employed to study ultrasonic scattering by Albunex® bubbles. These bubbles are approximately gas-filled microspheres surrounded by a shell of human serum albumin that behaves collectively as a continuous, damped, elastic solid. An exact solution, written in terms of a modal series representing the contributions from various vibrational modes of the bubbles, is presented for the acoustic scattering function. Results are obtained from numerical computation and are compared with the previous results. It is shown that (1) at frequencies below or slightly higher than the resonance, acoustic scattering by Albunex bubbles is nearly omnidirectional and bears similarities to that by usual air bubbles, and the results agree with the previous results for these frequencies; (2) the resonance frequency for a given Albunex bubble tends to increase with the shear modulus of the elastic shell which, however, appears to have little effect on acoustic scattering at high frequencies or from large bubbles; (3) acoustic scattering by Albunex bubbles seems not sensitive to the bulk modulus in the shell for a wide range of frequency and bubble size. The results also reveal that the scattering by Albunex bubbles can be highly anisotropic when the frequency is somehow above the resonance, and the previous theories solely based on the radial pulsation of the bubbles overestimate the sound scattering cross section in this case. In addition, some inconsistencies in the previous results are addressed. Furthermore, the forward scattering theorem is used to study the acoustic attenuation by Albunex bubbles. According to this theorem, the acoustic extinction cross section is related to the imaginary part of the scattering function in the forward direction. The forward scattering function is calculated and compared with the backward scattering function. The results show that the scattering function in the two directions can differ significantly from each other under certain conditions.
Microscopic theory of hydrogen in silicon devices (2000)

Incorporation of hydrogen has a strong effect on the characteristics of silicon devices. A fundamental understanding of the microscopic mechanisms is required in order to monitor and control the behavior of hydrogen. First-principles calculations have been instrumental in providing such understanding. We first outline the basic principles that govern the interaction between hydrogen and silicon, followed by an overview of recent first-principles results for hydrogen interactions with silicon. We show that H/sub 2/ molecules are far less inert than previously assumed. We then discuss results for motion of hydrogen through the material, as relating to diffusion and defect formation. We also discuss the enhanced stability of Si-D compared to Si-H bonds, which may provide a means of suppressing defect generation. We present a microscopic mechanism for hydrogen-hydrogen exchange, and examine the metastable /spl equiv/SiH/sub 2/ complex formed during the exchange process. Throughout, we highlight issues relevant for hydrogen in amorphous silicon (used in solar cells, sensors and displays) and in Si-SiO/sub 2/ structures (used in integrated circuits). The broader impact of first-principles calculations on computational electronics will also be discussed.
Dose reproducibility in Axcelis GSD implanters using Stabil-Ion gauge (2002)

Long-term dose reproducibility and tool to tool dose matching in the Axcelis GSD end-station is critically dependent on process chamber pressure measurement and Pressure Compensation factor selection. Pressure Compensation factor (PCOMP) determination is well established. Pressure measurement in the GSD end-station depends on accurate, repeatable gauge capability: incorrect pressure measurements directly lead to dose errors. For example, the dose equation using PCOMP tells us that for a modest PCOMP value of 30%, a chamber pressure measurement error of 2E-5 torr can result in a dose error up to 6% at normal process pressures. The original HCIG used for pressure measurement was not capable of meeting the requirements for good dose control since gauge to gauge differences were not controlled and gauge accuracy was only on the order of 25%. Axcelis introduced the Granville-Phillips 360 Stabil-Ion gauge to improve dose reproducibility through much improved gauge to gauge matching (+/-6%) and more accurate gauge output. This paper discusses the details of the care and feeding of the Stabil-Ion gauge system and its impact on process dose and process trends.
