Chairperson and Faculty Gender in Academic Emergency Medicine Departments (2006)

Objectives: Despite the influx of female physicians in academic medicine departments, there are a small number of women in faculty and departmental leadership positions in emergency medicine (EM). The objective of this study was to determine if the gender of the chairperson of an academic EM department is associated with the gender of the residency program director (RPD) and gender proportion of its faculty. Methods: This was a retrospective analysis of 133 academic EM departments using the Society for Academic Emergency Medicine online residency catalog, program Web site, or e-mail. Main outcome measures were proportion of female EM faculty and gender of the RPD. Results: Data were available for 133 academic departments. Women chaired 7.5% (n= 10) of departments and comprised 22.3% of all faculty and 15.0% (n= 20) of RPD positions. EM departments that were chaired by women had a significantly higher percentage of female faculty compared with those led by men (31% vs. 22%; p = 0.01). Similarly, departments that were chaired by women had a significantly higher proportion of female RPDs compared with those chaired by men (50% vs. 12%; p < 0.01). Compared with departments chaired by men, the RPD was 5.0 times (95% confidence interval = 1.9 to 27.8; p < 0.01) more likely to be a woman if the chairperson was also a woman. Conclusions: An academic EM department was more likely to have a higher proportion of female faculty and a female RPD when the department chairperson was female.
Effective localized collection and identification of airborne species through electrodynamic precipitation and SERS-based detection (2013)

Various nanostructured sensor designs currently aim to achieve or claim single molecular detection by a reduction of the active sensor size. However, a reduction of the sensor size has the negative effect of reducing the capture probability considering the diffusion-based analyte transport commonly used. Here we introduce and apply a localized programmable electrodynamic precipitation concept as an alternative to diffusion. The process provides higher collection rates of airborne species and detection at lower concentration. As an example, we compare an identical nanostructured surfaced-enhanced Raman spectroscopy sensor with and without localized delivery and find that the sensitivity and detection time is improved by at least two orders of magnitudes. Localized collection in an active-matrix array-like fashion is also tested, yielding hybrid molecular arrays on a single chip over a broad range of molecular weights, including small benzenethiol (110.18 Da) and 4-fluorobenzenethiol (128.17 Da), or large macromolecules such as anti-mouse IgG (~150 kDa).
Toeplitz Block Matrices in Compressed Sensing (2008)

Recent work in compressed sensing theory shows that $n\times N$ independent and identically distributed (IID) sensing matrices whose entries are drawn independently from certain probability distributions guarantee exact recovery of a sparse signal with high probability even if $n\ll N$. Motivated by signal processing applications, random filtering with Toeplitz sensing matrices whose elements are drawn from the same distributions were considered and shown to also be sufficient to recover a sparse signal from reduced samples exactly with high probability. This paper considers Toeplitz block matrices as sensing matrices. They naturally arise in multichannel and multidimensional filtering applications and include Toeplitz matrices as special cases. It is shown that the probability of exact reconstruction is also high. Their performance is validated using simulations.

Certified real‐time solution of the parametrized steady incompressible Navier–Stokes equations: rigorous reduced‐basis <i>a posteriori</i> error bounds (2005)

Abstract We present a technique for the evaluation of linear‐functional outputs of parametrized elliptic partial differential equations in the context of deployed (in service) systems. Deployed systems require real‐time and certified output prediction in support of immediate and safe (feasible) action. The two essential components of our approach are (i) rapidly, uniformly convergent reduced‐basis approximations, and (ii) associated rigorous and sharp a posteriori error bounds; in both components we exploit affine parametric structure and offline–online computational decompositions to provide real‐time deployed response. In this paper we extend our methodology to the parametrized steady incompressible Navier–Stokes equations. We invoke the Brezzi–Rappaz–Raviart theory for analysis of variational approximations of non‐linear partial differential equations to construct rigorous , quantitative , sharp , inexpensive a posteriori error estimators. The crucial new contribution is offline–online computational procedures for calculation of (a) the dual norm of the requisite residuals, (b) an upper bound for the ‘ L 4 (Ω)‐ H 1 (Ω)’ Sobolev embedding continuity constant, (c) a lower bound for the Babuška inf–sup stability ‘constant,’ and (d) the adjoint contributions associated with the output. Numerical results for natural convection in a cavity confirm the rapid convergence of the reduced‐basis approximation, the good effectivity of the associated a posteriori error bounds in the energy and output norms, and the rapid deployed response.

Biodiesel production from waste frying oil: Conversion monitoring and modeling (2003)

Biodiesel is a clean-burning substitute for petroleum-based diesel produced from virgin or waste vegetable oils and animal fats. One obstacle to the development of biodiesel is its high cost compared to petroleum diesel. Using waste frying oil instead of virgin oil can significantly reduce the high production cost. In our lab, promising preliminary results have indicated that transesterification of waste frying oil catalyzed by sulphuric acid has sufficient commercial feasibility to warrant further investigation. In order to better understand the acid-catalyzed transesterification process and to optimize the process yield, an empirical study of the reaction kinetics was carried out. A mixture design for feed compositions at various temperatures was used to determine their effects on conversion rates and yields. Empirical models were built to describe the relationships of interest. Rate of mixing, feed composition and temperature were chosen as independent factors in this study. Intensity of mixing was found to have no significant effect on the yield over 100 rpm. The methanol to oil ratio and temperature were the most significant factors affecting the yield. Finally, a region of optimum operating conditions was determined from the models. Analytical methods played an important role in our study. The extent of the reaction was followed off-line by gel permeation chromatography (GPC) and compared to results using an off-line infrared sensor based on attenuated total reflectance-Fourier transform infrared (ATR-FTIR) spectroscopy. The development, use and evaluation of the off-line method were discussed. The reproducibility of both methods was found to be excellent (≤1%); data obtained from both methods were found to be reliable. Finally, a comparison of the two methods showed good agreement (within 2%) in the monitoring of the transesterification reaction.
Multi-band reflectarray using mushroom structure (2012)

This paper shows a study of the multiband mushroom reflectarray design. We have achieved multi-band reflectarray to satisfy desired reflection phase, using TE incidence for low frequency and TM incidence for high frequency and changing two directional gap sizes corresponding to each polarization. We show the reflectarray that can reflects same direction for same incidence direction at dual frequencies.
SCALE NUCLEATION ON A HEAT TRANSFER SURFACE AND ITS PREVENTION (1978)

Abstract A review is presented of the parameters influencing the nucleation of scale from natural waters on a heat transfer surface and its prevention. Little is known about this phenomenon in comparison to subsequent scale growth. The importance of variations in pressure and temperature, which directly change the saturation limit of the scaling species, are emphasized. The influence of fluid motion, the type of heat transfer surface material and its condition, on scale nucleation, is also discussed. Both chemical and physical methods of water treatment used to prevent nucleation and growth of scale are reviewed. It is considered that more work is required before a full understanding of scale nucleation can be obtained and optimum preventative measures undertaken.
Antagonism of Inhalant and Volatile Anesthetic Enhancement of Glycine Receptor Function (2001)

Recent studies suggest that alcohols, volatile anesthetics, and inhaled drugs of abuse, which enhance gamma-aminobutyric acid, type A, and glycine receptor-activated ion channel function, may share common or overlapping molecular sites of action on these receptors. To investigate this possibility, these compounds were applied singly and in combination to wild-type glycine alpha(1) receptors expressed in Xenopus laevis oocytes. Data obtained from concentration-response curves of the volatile anesthetic enflurane constructed in the presence and absence of ethanol, chloroform, or toluene were consistent with competition for a common binding pocket on these receptors. A mutant glycine receptor, insensitive to the enhancing effects of ethanol but not anesthetics or inhalants, demonstrated antagonism of anesthetic and inhalant effects on this receptor. Although ethanol (25-200 mm) had no effect on its own in this receptor, it was able to inhibit reversibly the enhancing effect of enflurane, toluene, and chloroform in a concentration-dependent manner. These data suggest the existence of overlapping molecular sites of action for ethanol, inhalants, and volatile anesthetics on glycine receptors and illustrate the feasibility of pharmacological antagonism of the effects of volatile anesthetics.

Development of TiO<sub>2</sub> containing hardmasks through plasma-enhanced atomic layer deposition (2017)

With the increasing prevalence of complex device integration schemes, trilayer patterning with a solvent strippable hardmask can have a variety of applications. Spin-on metal hardmasks have been the key enabler for selective removal through wet strip when active areas need to be protected from dry etch damage. As spin-on metal hardmasks require a dedicated track to prevent metal contamination and are limited in their ability to scale down thickness without compromising on defectivity, there has been a need for a deposited hardmask solution. Modulation of film composition through deposition conditions enables a method to create TiO2 films with wet etch tunability. This paper presents a systematic study on development and characterization of plasma-enhanced atomic layer deposited (PEALD) TiO2-based hardmasks for patterning applications. We demonstrate lithographic process window, pattern profile, and defectivity evaluation for a trilayer scheme patterned with PEALD-based TiO2 hardmask and its performance under dry and wet strip conditions. Comparable structural and electrical performance is shown for a deposited versus a spin-on metal hardmask.

Volumetric Cloud Rendering: An Animation of Clouds (2014)

This paper demonstrates a production workflow for a volumetric-rendering-based short animation about clouds. The animation is based on the concept of a giant fish swimming in the sky from Zhuangzi's philosophical story. The algorithm and implementation for the modeling and rendering of clouds are also presented. A renderer was developed that uses the OpenVDB library for data storage, fast retrieving and grid manipulation. A user-friendly pipeline was also developed for cloud modeling and rendering, which used Python and XML for adjusting rendering parameters. The pipeline includes Maya to build the rough cloud model and Houdini to calculate the interior light points. Final compositing was done in Nuke. Several MEL and Python scripts were also used to retrieve camera and light information from Maya and Houdini, thereby facilitating the production process.
New Silicon‐Containing Polyquinolines: Synthesis, Characterization, and Electroluminescence (2005)

Abstract Summary: This study reports the synthesis, characterization, and electroluminescent device application of three new silicon‐containing polyquinolines: poly(2,2′‐(bis( p ‐phenyl)diphenylsilane)‐6,6′‐bis(4‐phenyl quinoline)), poly(2,2′‐(bis( p ‐phenyl)octylmethylsilane)‐6,6′‐bis(4‐phenyl quinoline)), and poly(2,2′‐(bis( p ‐phenyl)diphenylsilane)‐6,6′‐bis(4‐hexylquinoline)). The polymers with alkyl side chains were soluble in organic solvents. The new polymers showed robust thermal properties with glass transitions of 161–339 °C. Cyclic voltammetry of the polymers revealed quasi‐reversible reductions with onsets of −1.55 to −1.71 V (vs SCE) and corresponding electron affinities of 2.69–2.85 eV. Organic light‐emitting devices using new polyquinolines as emissive materials showed blue (CIE coordinates = 0.21, 0.20) or blue‐green (0.23, 0.36) electroluminescence with a moderate brightness (≈140 cd · m −2 ) and efficiency (0.04%). The results demonstrate that silicon‐containing polyquinolines are promising n‐type wide band‐gap semiconductors for organic electronics.

Purification of common light chain IgG-like bispecific antibodies using highly linear pH gradients (2016)

Monovalent bispecific antibodies (BsAbs) are projected to have broad clinical applications due to their ability to bind two different targets simultaneously. Although they can be produced using recombinant technologies, the correct pairing of heavy and light chains is a significant manufacturing problem. Various approaches exploit mutations or linkers to favor the formation of the desired BsAb, but a format using a single common light chain has the advantage that no other modification to the antibody is required. This strategy reduces the number of formed molecules to three (the BsAb and the two parent mAbs), but the separation of the BsAb from the two monovalent parent molecules still poses a potentially difficult purification challenge. Current methods employ ion exchange chromatography and linear salt gradients, but are only successful if the difference in the observed isoelectric points (pIs) of two parent molecules is relatively large. Here, we describe the use of highly linear pH gradients for the facile purification of common light chain BsAbs. The method is effective at separating molecules with differences in pI as little as 0.10, and differing in their sequence by only a single charged amino acid. We also demonstrate that purification resins validated for manufacturing are compatible with this approach.
The methylation profiles of PRDM promoters in non&ndash;small cell lung cancer (2018)

The expression of <i>PRDM2</i>, <i>PRDM5</i>, and <i>PRDM16</i> is low or absent in NSCLC, and this is mainly due to gene promoter methylation. Smoking may be an important cause of <i>PRDM2</i> and <i>PRDM16</i> methylation in NSCLC.
Matrix Metalloproteinase Inhibition Enhances the Rate of Nerve Regeneration In Vivo by Promoting Dedifferentiation and Mitosis of Supporting Schwann Cells (2010)

After peripheral nerve injury, Schwann cells (SCs) vigorously divide to survive and produce a sufficient number of cells to accompany regenerating axons. Matrix metalloproteinases (MMPs) have emerged as modulators of SC signaling and mitosis. Using a 5-bromo-2-deoxyuridine (BrdU) incorporation assay, we previously found that a broad-spectrum MMP inhibitor (MMPi), GM6001 (or ilomastat), enhanced division of cultured primary SCs. Here, we tested the hypothesis that the ability of MMPi to stimulate SC mitosis may advance nerve regeneration in vivo. GM6001 administration immediately after rat sciatic nerve crush and daily thereafter produced increased nerve regeneration as determined by nerve pinch test and growth-associated protein 43 expression. The MMPi promoted endoneurial BrdU incorporation relative to vehicle control. The dividing cells were mainly SCs and were associated with growth-associated protein 43-positive regenerating axons. After MMP inhibition, myelin basic protein mRNA expression (determined by Taqman real-time quantitative polymerase chain reaction) and active mitosis of myelin-forming SCs were reduced, indicating that MMPs may suppress their dedifferentiation preceding mitosis. Intrasciatic injection of mitomycin,the inhibitor of SC mitosis, suppressed nerve regrowth, which was reversed by MMPi, suggesting that its effect on axonal growth promotion depends on its promitogenic action in SCs. These studies establish novel roles for MMPs in peripheral nerve repair via control of SC mitosis, differentiation, and myelin protein mRNA expression.
Simple analysis of MRC receivers for MC-CDMA systems in fading channels (2002)

Multicarrier code-division multiple-access (MC-CDMA) is a transmission scheme that combines orthogonal frequency division multiplexing (OFDM) signaling with the CDMA technique allowing efficient, utilization of the bandwidth in broadband mobile radio channels. In this paper, a new practical technique based on alternative Gaussian approximation (AGA) for determining the bit error rate (BER) of maximal-ratio combining (MRC) receivers for MC-CDMA systems with multiple active users in frequency selective Rayleigh fading channels is presented. The analysis assumes that different subcarriers experience independent fading channels, which are not necessarily identically distributed. Unlike other existing analysis methods, this new procedure takes advantage of an alternate integral representation of the conditional BER, leading to the final average BER in the form of a single finite range integral and an integrand composed of an elementary function which can be easily computed numerically. The accuracy of the proposed approach based on AGA is demonstrated with computer simulations results in a Rayleigh fading channel.
INTERACTION OF PLANT PHENOLS AND SALIVARY PHENOLASES IN THE RELATIONSHIP BETWEEN PLANTS AND HEMIPTERA (1969)

Most sucking bugs secrete a salivary phenolase, at least some together with a diphenolic substrate. No function for this system has yet been demonstrated, but phytopathological fungi also secrete phenolases, and there is evidence that attacks both by sedentary insects and by fungi stimulate a defence mechanism in plants based on the oxidation of phenols to quinones. Details of the interaction are uncertain, but it seems possible that some of the toxic reactions of plants to the feeding of sucking insects are similar biochemically to the toxic or hypersensitive reactions of plants to invading fungi. Insect galls are classically associated with “tannins”, and phenols have been implicated particularly in the resistance of plants to cecidogenic insects such as the grape phylloxera and the woolly aphis. It is suggested that the production of quinones by the oxidation of phenols was evolved by plants as a non‐specific mechanism that resists invading organisms, and that the further oxidation of the quinones to non‐toxic polymers is a means by which some invading organisms have overcome this resistance. Stimulation of the growth of some of the plant's cells as a by‐product of the interaction is biochemically possible and is suggested as an explanation of how cecidogenesis by insects has evolved. ZUSAMMENFASSUNG WECHSELWIRKUNG VON PFLANZLICHEN PHENOLEN UND SPEICHELPHENOLASEN IN DEN BEZIEHUNGEN ZWISCHEN INSEKT UND PFLANZE Die meisten pflanzensaftsaugenden Wanzen scheiden im Speichel eine Phenolase ab, zumindest einige bei einem diphenolischen Substrat. Bisher konnte keine Funktion dieses Systems nachgewiesen werden; jedoch scheiden phytopathogene Pilze ebenfalls Phenolasen ab, und es besteht die Wahrscheinlichkeit, daß Angriffe sowohl von sessilen Insekten wie von Pilzen in den Pflanzen einen Abwehrmechanismus auslösen, der auf der Oxydation von Phenolen zu Chinonen beruht. Einzelheiten der Wechselwirkung sind unsicher, aber es scheint möglich, daß einige der toxischen Reaktionen der Pflanzen gegenüber beißenden oder saugenden Insekten biochemisch den toxischen oder Überempfindhchkeits‐Reaktionen der Pflanzen gegenüber eindringenden Pilzen ähneln. Insektengallen sind gekennzeichnet durch ihre Verbindung mit “Tanninen”, und Phenole sind besonders mit der Resistenz von Pflanzen gegenüber cecidogenen Insekten, wie der Reblaus und der Blutlaus, in Beziehung gebracht worden. Es wird vermutet, daß die Produktion von Chinonen durch die Oxydation von Phenolen von den Pflanzen als ein unspezifischer Mechanismus entwickelt worden ist, der dem eindringenden Fremd‐Organismus Widerstand leistet, und daß die weitere Oxydation der Chinone zu nicht‐toxischen Polymeren ein Mittel ist, durch das einige eindringende Organismen diese Resistenz überwunden haben. Wachstumsanregung für einige der Pflanzenzellen als Nebenprodukt dieser Wechselwirkung ist biochemisch möglich und wird als Erklärung dafür vermutet, wie sich Gallenbildung durch Insekten entwickelt hat.
