Stability analysis of time‐delay systems via Bessel inequality: A quadratic separation approach (2017)

Summary In this paper, new sufficient stability conditions for the asymptotic stability of time‐delay systems are presented using the quadratic separation approach. The time‐delay system is modeled as an interconnected closed‐loop system involving a linear transformation and delay‐dependent functions, representing the uncertainties brought by the delay. Those complex‐valued functions are then embedded into adequate norm‐bounded uncertainties, which lead to several stability results. The novelty of this approach relies on the introduction of new dedicated functions that are built in accordance to the Bessel inequality. They allow us to model the system as an uncertain feedback system and to control the accuracy of the inequality. Then, a sequence of linear matrix inequality conditions is proposed, which tends to the analytical bounds for both delay‐dependent stability and delay range stability, at least on examples.
Self-organized (111) faceted NiSi<sub>2</sub>source and drain for advanced SOI MOSFETs (2006)

The advantages of this source and drain structure are a superior short-channel effect (SCE) immunity and a very small parasitic resistance. The SCE is suppressed by a trapezoidal shape of the channel and by a small variation in the channel length that is obtained thanks to the epitaxial growth of NiSi <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sub> on Si.

Monoclonal Antibody‐Mediated, Complement‐Independent Binding of Human Tumor Necrosis Factor‐α to Primate Erythrocytes via Complement Receptor 1 (1997)

Monoclonal antibody (MAb)-based heteropolymers (HP) were used to simulate immune adherence. The HP is constructed by cross-linking MAbs that recognize complement receptor 1 (CR1) and tumor necrosis factor-alpha (TNF-alpha). 125I-labeled TNF-alpha was cocultured with either sheep, monkey, or human erythrocytes in the presence or absence of HP. Human erythrocytes demonstrated 63% +/- 0 (mean +/- SD) binding of 125I-labeled TNF-alpha, while binding of 125I-labeled TNF-alpha in the absence of HP was 4% +/- 1% (P < .001). Monkey erythrocytes showed similar results, while sheep erythrocytes (which lack CR1) demonstrated low binding. The effect of HP binding on biologic activity of TNF-alpha was examined in an assay of stimulated human neutrophils. The HP completely inhibited the ability of TNF-alpha to prime neutrophils, occurring regardless of the presence or absence of erythrocytes but solely dependent on the addition of HP. Thus, the HP facilitated specific, saturable, and significant binding of 125I-labeled TNF-alpha to primate erythrocytes in vitro.
Interocular differences in visual function in normal subjects (1996)

A commonly used clinical technique for determining whether visual function is abnormal, particularly when a patient is suspected of having unilateral or asymmetric disease, is to compare the visual function of the 'suspect' eye to that of the normal eye. This assumes that in normal patients visual function in each eye is equal and that this symmetry is maintained with age. To determine the extent of normal symmetry for clinical measures of visual function, we assessed high and low contrast visual acuity, letter contrast sensitivity and motion sensitivity (Dmin) in both eyes of a group of 91 subjects spanning an age range of 21 to 82 years. For the whole group the interocular differences in sensitivity for each of the tests approximated a Gaussian distribution. The results demonstrate that interocular differences should exceed more than 0.16 and 0.17 logMAR (approximately 2 lines) for high and low contrast visual acuity respectively, before patients can be considered to be outside the range of normality. For the Pelli-Robson Chart, interocular differences must exceed 0.23 log CS (1.5 triplets, 4.5 letters) and for Dmin, more than 0.35 log minarc for the differences to be considered abnormal. For low contrast letter visual acuity, there was a trend for the absolute interocular differences to increase significantly with age, but asymmetry remained relatively constant for the other visual measures.
Anti- <i>Candida</i> Activity of a New Platinum Derivative (2000)

A new platinum derivative of the form H[Pt(IV)(Hdigly)Cl(2)(OH)(2)] (Hdigly==glycylglycine) damaged the Candida albicans cell membrane and inhibited the growth of the cells. The cytotoxic activity of H[Pt(IV)(Hdigly)Cl(2)(OH)(2)] on mammalian cells was 10-fold lower than that of cis-diammine-dichloroplatinum (cisplatin). Substitution of platinum for peptides is effective for enhancement of antifungal activity and reduction of the toxicity to mammalian cells.
Large Intracytoplasmic Body in Lung Cancer Compared with Clara Cell Granule (1987)

Large intracytoplasmic bodies in tumor cells of different pulmonary neoplasms were morphologically studied. In 27 of 105 cases of surgically resected lung tumors, large intracytoplasmic bodies were found in 13 adenocarcinomas, 9 squamous cell carcinomas, and 5 large cell carcinomas. These bodies appeared most frequently in large cell carcinomas and in well-differentiated adenocarcinomas, particularly of the Clara cell type. In squamous cell carcinomas, they were seen only in nonkeratinizing polygonal tumor cells. Large intracytoplasmic bodies in different pulmonary tumors and Clara cell granules in Clara cell carcinoma showed similar histochemical staining reactions. Electron microscopically, both large intracytoplasmic bodies and Clara cell granules appeared membrane bound and contained electron-dense matrices. The results suggest that large intracytoplasmic bodies in lung carcinoma cells may be a variant of Clara cell granules, only differing in size.
Creating artificial global history to improve branch prediction accuracy (2009)

Modern processors require highly accurate branch prediction for good performance. As such, a number of branch predictors have been proposed with varying size and complexity. This work identifies techniques to improve the accuracy of most predictors. It is especially effective with smaller, simpler predictors, allowing those predictors to be competitive with more expensive and complex variants.
Catalytic Electrophilic CH Silylation of Pyridines Enabled by Temporary Dearomatization (2015)

A CH silylation of pyridines that seemingly proceeds through electrophilic aromatic substitution (SE Ar) is reported. Reactions of 2- and 3-substituted pyridines with hydrosilanes in the presence of a catalyst that splits the SiH bond into a hydride and a silicon electrophile yield the corresponding 5-silylated pyridines. This formal silylation of an aromatic CH bond is the result of a three-step sequence, consisting of a pyridine hydrosilylation, a dehydrogenative CH silylation of the intermediate enamine, and a 1,4-dihydropyridine retro-hydrosilylation. The key intermediates were detected by (1) H NMR spectroscopy and prepared through the individual steps. This complex interplay of electrophilic silylation, hydride transfer, and proton abstraction is promoted by a single catalyst.
Observation of level-crossing effects in optogalvanic spectroscopy (1981)

Optogalvanic signals arising from a group of transitions in Zr I have been studied under irradiation of a cold cathode glow discharge with polarised laser light.The signals increase with the application of a magnetic field of a few gauss crossed with the symmetry axis of the polarisation, but the change is not related to the direction of current in the discharge.The occurrence of these magnetic resonances depends on at least partial saturation of the optogalvanic signals.The empirical evidence leads to the conclusion that the resonances result from changes of occupation probability in the excited state upon removal of degeneracy by the magnetic field-a non-linear, level-crossing effect.
Reaction Modeling and Optimization Using Neural Networks and Genetic Algorithms:  Case Study Involving TS-1-Catalyzed Hydroxylation of Benzene (2002)

This paper proposes a hybrid process modeling and optimization formalism integrating artificial neural networks (ANNs) and genetic algorithms (GAs). The resultant ANN−GA strategy has the advantage that it allows process modeling and optimization exclusively on the basis of process input−output data. In the hybrid strategy, first an ANN-based process model is developed from the input−output process data. Next, the input space of the model representing process input variables is optimized using GAs, with a view to simultaneously maximize multiple process output variables. The GAs are stochastic optimization methods possessing certain unique advantages over the commonly used gradient-based deterministic algorithms. The efficacy of the hybrid formalism has been evaluated for modeling and optimizing the zeolite (TS-1)-catalyzed benzene hydroxylation to phenol reaction whereby several sets of optimized operating conditions have been obtained. A few optimized solutions have also been subjected to the experimental verification, and the results obtained thereby matched the GA-maximized values of the three reaction output variables with a good accuracy.
The Concept of Compatibility in Polyblends (1971)

When liquids are mixed to form a homogeneous and single-phase mixture, they are said to be compatible. This mixing is straightforward, and the result is easily observed; mixing polymers is quite different. From thermodynamic, kinetic, and mechanical considerations, a homogeneous single-phase polyblend is highly improbable. No polyblend is compatible if compatibility means homogeneity and single-phase morphology. Conceptually, compatibility is a representation of how close a polyblend can approach this ultimate state of molecular mixing. Phenomenologically, it is a relative measure of the degree of heterogeneity of the polyblend—i.e., how fine one polymer is dispersed in another. Compatibility of a polyblend is subject to differences in experimentation and interpretation of result. One should describe it by giving the sample history and method and instrument used to determine its degree of heterogeneity.
Extended Mobility Procedures for EVPN-IRB (2019)

Procedure to handle host mobility in a layer 2 Network with EVPN
control plane is defined as part of RFC 7432. EVPN has since evolved
to find wider applicability across various IRB use cases that include
distributing both MAC and IP reachability via a common EVPN control
plane. MAC Mobility procedures defined in RFC 7432 are extensible to
IRB use cases if a fixed 1:1 mapping between VM IP and MAC is assumed
across VM moves. Generic mobility support for IP and MAC that allows
these bindings to change across moves is required to support a broader
set of EVPN IRB use cases, and requires further consideration. EVPN
all-active multi-homing further introduces scenarios that require
additional consideration from mobility perspective. This document
enumerates a set of design considerations applicable to mobility
across these EVPN IRB use cases and defines generic sequence number
assignment procedures to address these IRB use cases.

Accuracy of three methods for predicting concentrations of free phenytoin. (1987)

Predictions of free (unbound) serum phenytoin concentration by three methods were compared with results obtained by the Abbott TDx Free Phenytoin ultrafiltration and fluorescence-polarization immunoassay technique. Data were obtained for hospitalized adults who had been receiving phenytoin for at least five days and were free of renal or hepatic disease. Total phenytoin concentration was determined, and free phenytoin concentration was measured in ultrafiltrate at 25 degrees C. For each patient, measured concentrations of total phenytoin and albumin were used to predict free phenytoin concentrations by the Gugler method, the Sheiner-Tozer nomogram, and the Sheiner-Tozer equation. Mean measured percentages of free phenytoin were 17.79%, 12.13%, and 8.73%, respectively, for patients with albumin concentrations of less than 2 g/dL (n = 5), 2-3 g/dL (n = 18), and greater than 3 g/dL (n = 26). There was a strong correlation between actual and predicted free phenytoin concentrations for each of the methods, but all methods were found to lack precision. All methods also exhibited bias, as demonstrated by overprediction of the free concentration; however, none of the methods exhibited bias when the difference between the in vitro temperature of 25 degrees C and the in vivo temperature of 37 degrees C was considered. Because of their poor precision, the three methods evaluated in this study are not recommended for predicting free phenytoin concentration.
Mast Cells in Neovascularized Human Coronary Plaques Store and Secrete Basic Fibroblast Growth Factor, a Potent Angiogenic Mediator (2004)

The present work reveals a novel source of bFGF in human coronary arteries, the intimal and adventitial MCs. The association of bFGF-positive MCs with microvessels and with the severity of atherosclerosis suggests that coronary MCs, by releasing bFGF, may play a role in angiogenesis and progression of coronary plaques.
DNA-Fragments Resistant to Endodeoxyribonuclease Hydrolysis PCR-Amplification using 7-Deaza-2′-deoxyguanosine Triphosphate in Place of dGTP (1991)

Abstract 7-Deaza-2′-dcoxyeuanosine triphosphate was used instead of dGTP during PCR-amplification of a pUC 18 fragment of 501 base pairs. The oligomer containing C7Gd was protected from hydrolysis by various endodeoayn'bonucleases when the 7-deazapurine nucleoside was localized at the 3′- or the 5′-position of the cleavage site.

Effectiveness of Adenoidectomy on Tympanostomy Tubes Retention Duration (2011)

Background: The children with middle ear effusion need repeated re-tympanostomies. Adenoidectomy is an effective surgical intervention in the management of chronic otitis media with effusion in conjunction with in-sertion of tympanostomy tubes (TTs). To find out whether TTs in different positions decrease the rate of re-tympanostomies study was done. Methods: The present study retrospectively evaluated the effectiveness of adenoidectomy on retention of Shepard TTs in antero-inferior quadrant (AIQ) and postero-inferior quadrant (PIQ) with chronic, persistent or recurrent otitis media. Eighty-five children (one-hundred and seventy ears) underwent bilateral myringotomy and TTs placement with and without adenoidectomy with informed consent. Results: According to the TTs retention duration rate, there was a significant difference between adenoidec-tomy and non-adenoidectomy groups in AIQ. Conclusion: It was concluded that TTs placement in the AIQ in conjunction with adenoidectomy showed better improvement and prolonged ventilation. This study suggests that adenoidectomy is an effective surgical intervention in the management of otitis media especially when it is performed in conjunction with insertion of TTs. This significantly decreases tube extrusion rate especially in an AIQ, which might be due to improving eustachian tube function that consequently reduces repeated otitis media.
Wavefront phase retrieval with multi-aperture Zernike filter for atmospheric sensing and adaptive optics applications (2016)

A novel scintillation resistant wavefront sensor based on a densely packed array of classical Zernike filters, referred to as the multi-aperture Zernike wavefront sensor (MAZ-WFS), is introduced and analyzed through numerical simulations. Wavefront phase reconstruction in the MAZ-WFS is performed using iterative algorithms that are optimized for phase aberration sensing in severe atmospheric turbulence conditions. The results demonstrate the potential of the MAZ-WFS for high-resolution retrieval of turbulence-induced phase aberrations in strong scintillation conditions for atmospheric sensing and adaptive optics applications.
Fragrance Chemistry — Milestones and Perspectives (2001)

This mini-review on Fragrance Chemistry focuses on milestones in the timelines of musk, ionone/ woody and sandalwood odorants, as well as on new perspectives arising from the development of fragrance precursors. After a brief introduction of the history of perfumery, its mutual interaction with the chemistry of odorants, and the current state of the fragrance industry, the whole spectrum of musk odorants is discussed from the accidental discovery of nitro musks like Musk Ketone® via the parallel evolution of benzenoid and macrocyclic musks, to new structures like Cyclomusk® and Moxalone®. Following a description of the structure elucidation of violet odorants, ionone and irone, lso ESuper® and the structurally related Georgywood®, but also Koavone® and Timberol® are treated. Weissenborn's discovery of terpenylcyclohexanols lead to sandalwood synthetics that today are mainly derivatives of campholenic aldehyde like Sandalore®, Sandal Mysore Core®, Polysantol®, Ebanol®, and Javanol®. Finally, lipase labile precursor systems, for instance digeranyl succinate, or UV-radiation labile ones like citronellyl coumarate and citronellyl cyclohexylglyoxylate are presented, and views on 'secondary benefits', 'anti-perfumes' and exclusive 'Editions de Parfums' conclude this overview on the driving forces and the serendipities in the chemistry of fragrant substances.

Regulation of Phosphatidylcholine Biosynthesis by the Methylation Pathway in Saccharomyces cerevisiae (1969)

Abstract The labeling of the methylated phospholipids of Saccharomyces cerevisiae has been studied with methionine-methyl-14C, serine-3-14C, and choline-1,2-14C as precursors. It was found that inclusion of 1 mm choline in the growth media greatly lowered the rate of labeling of the methylated phospholipids by methionine and serine; sterol labeling was unaffected. It is suggested that this is a result of repression of synthesis of the specific N-methyl transferases involved in the biosynthesis of phosphatidylcholine. A study in vitro with methyl-14C-S-adenosylmethionine as methyl donor showed that particles prepared from cells grown in the absence of choline had a much higher rate of phospholipid methylation than the particles prepared from choline-grown cells. Incorporation rates of choline in vivo into phosphatidylcholine were not greatly altered by the presence of choline in the growth medium.
Coherent dynamics of excitons in shallow superlattices (2003)

Summary form only given. Shallow superlattices are very promising for optoelectronic devices due to their high nonlinearity and fast carrier sweep-out. Detailed investigations of the electronic structure (such as the excitonic binding energy) and the high field transport properties have been scarce, however. We have investigated different shallow superlattices of GaAs-AlGaAs using spectrally resolved transient four wave mixing under various excitation conditions.
Automatic Berthing Experiments Using "Shioji-Maru" (1990)

In order to operate the berthing maneuver automatically, a control system was developed. This system is composed of a ranging system and a controller. A control logic based on a prediction of a motion was adopted and a feed back control was used subsidiarily to improve the performance of the system. Actual trial using this automatic berthing system was executed. And following results were obtained. (1) The smooth course was obtained during the trial. (2) The final position error and the berthing velocity seem to be acceptable. (3) A control logic based on a prediction of the motion did not operate successfully but a feed back control recovered this well.
Atomic Frequency Standards for Ultra-High-Frequency Stability (1987)

The general features of the Hg-199(+) trapped-ion frequency standard are outlined and compared to other atomic frequency standards, especially the hydrogen maser. The points discussed are those which make the trapped Hg-199(+) standard attractive: high line Q, reduced sensitivity to external magnetic fields, and simplicity of state selection, among others.
5-HT Receptor-Associated Proteins (FRAPs) (2006)

Dysfunction in the serotonergic system contributes to the etiology and pathophysiology of a variety of neuropsychiatric and systemic disorders, and 5-hydroxytryptamine(5-HT) receptors as a group represent important therapeutic targets for many of these debilitating diseases. Encompassing a diverse group of proteins that interact with 5-HT receptors, 5-HT receptor-associated proteins (FRAPs) coordinate receptor targeting to the appropriate subcellular compartments, organization of networks of signaling and structural proteins (known as receptosomes), and calibration of receptor-mediated signal transduction, including desensitization, resensitization, and crosstalk with other signaling pathways. The study of FRAPs opens a decidedly wide arena for novel pharmaceutical research approaches. We will provide an overview of the burgeoning field of FRAPs, with a focus on their role in modulating signal transduction.
