A convex optimisation approach to robust observer-based H<SUB align=right>&infin; control design of linear parameter-varying delayed systems (2008)

This paper presents a convex optimisation method for observer-based control design of LPV neutral systems. Utilising the polynomials parameter-dependent quadratic functions and a suitable change of variables, the required sufficient conditions with high precision for the design of a desired observer-based control are established in terms of delay-dependent parameter-independent linear matrix inequalities. An observer-based controller guaranteeing asymptotic stability of the closed-loop system and satisfying a prescribed level of performance to the LPV neutral system with constant delay parameters is developed. A Lyapunov-Krasovskii method underlies the observer-based H∞ control design. A numerical example with simulation results illustrates the effectiveness of the methodology.

Interaction of Carbohydrates with Phosphatidylcholine Inverse Micelles (1992)

Abstract Small angle X‐ray scattering experiments indicate that egg phosphatidylcholine dissolved in benzene at a concentration of 12–50 mM organizes into approximately isometric inverse micelles with a size that depends upon the amount of water present. These inverse micelles can serve as self‐assembled hosts for monosaccharide derivatives. For a given amount of water, addition of carbohydrates causes an increase in the micelle size. In contrast, cyclohexane solutions of egg phosphatidylcholine contain highly anisotropic structures, possibly elongated rods. Monosaccharide derivatives can be extracted into these structures and are bound, at low water content, to the polar head groups. Upon addition of water the sugar is probably displaced from the polar head groups and gains some motional freedom in the water pool which is formed. This fact indicates that the polar head group of phosphatidylcholine interacts, probably by means of hydrogen bond formation, with monosaccharides and brings about their solubilization in nonpolar solvents.
On Designing PMI Kalman Filter for INS/GPS Integrated Systems With Unknown Sensor Errors (2014)

In this paper, a Kalman filter with proportional gain and multiintegral (PMI) gains is proposed to inertial navigation system (INS) and global positioning system (GPS) integration. A generalized fault is first introduced to represent the unexpected inertial sensors' biases resulted by environment condition changes or performance degradation of INS. Then, a linear time-varying system subject to fault is given to describe the dynamics of the INS/GPS integrated system. To achieve simultaneous estimation of navigation state and inertial sensors' biases, a PMI Kalman filter is developed in the framework of active fault tolerant filtering. Furthermore, a flight experiment is also given to illustrate the effectiveness of the proposed method. It is shown from the experimental results that the designed PMI Kalman filter can estimate biases more accurately than the traditional Kalman filter.
Stresses Around a Deep Well (1949)

Abstract In this paper, the theory of elasticity has been applied to the rock about adeep well. It is assumed that the rock has a modulus of elasticity and aPoisson's ratio and that the theory of elasticity applies. It is necessary toknow or assume the state of stress existing in the rock before it is penetratedby the well drill. The application of this theory indicates that stress concentration of shear, tensions, and compressions about the bore hole are of a high order. This isparticularly true when a horizontal compressive stress exists in one directiononly in the formation before drilling. If such an initial state of stressexists before drilling, then the rock will have stress concentrations of bothtension and compression at the same elevation and of such magnitude thatfailure of the rock is likely. Accompanying these is a shearing stress of largeproportion which is likely to produce spalling of the well walls. Internalpressure applied to the well bore will relieve the extreme compression but notthe tension and has little effect upon the shear. Plastic deformation of therock through a geological time tends to mitigate the stress concentrations. Introduction It has long been known that the stresses about holes and re-entrant cornersof elastic solids under the influence of loads are different and generally moreintense than those imposed upon the body elsewhere. Stress concentration at are-entrant corner can be reduced by increasing the radius of the fillet at thecorner. Stress concentration at the end of a crack in a plate undergoing eithertension or compression can be relieved appreciably by drilling a hole at thevery end of the crack. Also, stresses can be increased in an elastic body intension or compression by making a hole in it. The stress concentration isgreatest at the edge of the hole. Considerable knowledge of the stresses which exist about the bore hole of adeep well may be had by applying our knowledge of engineering mechanics; ormore particularly the theory of elasticity. It is, of course, necessary to makethe assumption that the rock is elastic and behaves as an elastic solid, thatis, that it obeys Hooke's law, has a modulus of elasticity, and a Poisson'sratio. It is also necessary to know, or assume, the state of stress whichexists in the rock prior to the penetration of the drill. With this knowledgeit is possible to compute the stresses about the bore hole. The problem can be simplified by considering several simple cases separatelyand then by applying the principle of superposition to solve the more complexcases which are made up of the simpler ones.

Ambipolar organic thin film transistors based on a soluble pentacene derivative (2011)

We report on ambipolar thin film transistors based on solution-deposited films of a pentacene derivative, 2,3-dicyano-6,13-bis-(triisopropylsilylethynyl)pentacene (2,3-CN2-TIPS-Pn). The ambipolar charge transport observed in this material is well balanced; the values of the hole and electron mobility are both about 2 × 10−3 cm2/Vs. The position of the highest occupied molecular orbital (HOMO) and lowest unoccupied molecular orbital (LUMO) of 2,3-CN2-TIPS-Pn with respect to the work function of the Au charge-injecting electrode and the arrangement of the molecules in the film, as deduced by grazing incidence x-ray diffraction analysis, contributes to explain the charge transport properties of 2,3-CN2-TIPS-Pn films.

American advances in wastewater treatment related to toxics control and to sludge management (1987)

Research emphasis by the United States Environmental Protection Agency in wastewater treatment has focused on control of toxics and sludge management. This paper describes highlights of the Environmental Protection Agency's research in these areas. The research on toxics control features studies on the treatability and fate of specific chemicals in conventional primary-secondary wastewater treatment and on toxicity reduction in treatment using bioassays as integrated toxicity monitors. The toxicity reduction approach uses both aquatic ecosystem and health effects assays. The research in sludge management describes a process for converting municipal sludges to oil using waste landfilling. The four year landfill evaluation revealed reduced landfill leachate pollutants and a more rapid onset of methane production for codisposal of sludges and solid waste compared to disposal of solid wastes only.
Modulation of Rapid Plasminogen Activator Inhibitor in Plasma by Stanozolol (1984)

Fibrinolytic activity in plasma euglobulin fractions can be increased by oral administration of stanozolol. This increase is not caused by increased synthesis or release of tissue-type plasminogen activator. A decreased level of fast acting t-PA inhibition is very probably the cause of the higher activity. These results suggest that this inhibition has a regulatory role on fibrinolysis in vivo.
Modeling and optimization of short Yb/sup 3+/-sensitized Er/sup 3+/-doped fiber amplifiers (1994)

Short high-concentration Yb/sup 3+/-sensitized Er/sup 3+/-doped fiber amplifiers are modeled and numerically investigated in the small-signal domain. Concentration quenching is included with a term quadratic in the concentration of excited Er/sup 3+/. We find that for fibers shorter than 1 m, the small-signal gain can be larger for sensitized fibers than for non-sensitized ones (31 dB gain vs. 22 dB at 5 cm). Without concentration quenching (e.g. for long fibers), Yb/sup 3+/-free amplifiers have a higher small-signal gain. The achievable gain of the sensitized amplifier is independent of the pump laser wavelength, if the Yb-concentration is correspondingly optimized. However, restrictions on allowable Yb-concentrations imply that for a specific pump wavelength, a finite range of amplifiers lengths is suitable.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
Targeted nucleotide exchange in the alkaline phosphatase gene of HuH-7 cells mediated by a chimeric RNA/DNA oligonucleotide (1997)

Although a variety of methods has been devised for modification of hepatic genes, none has been effective for long-term correction of genetic disorders. In this study, we employed a recently described novel experimental strategy for site-directed nucleotide exchange in genomic DNA of HuH-7 human hepatoma cells. A chimeric 2'-O-methylated-RNA/DNA oligonucleotide containing sequences complementary to 25 bases of the alkaline phosphatase gene was constructed as a duplex containing a G to A substitution at nucleotide 935. Cells were transfected with oligonucleotides for 48 hours, then harvested for DNA isolation and polymerase chain reaction (PCR) amplification of exon 6 of the alkaline phosphatase gene. Colony lifts were hybridized to 17 mer 32P-labeled oligonucleotide probes specific to the 935-G and 935-A sequences. Hybridizing colonies were grown, plasmid DNA isolated, and sequenced. Transfection efficiency was determined at 24 hours by nuclear uptake of fluorescein-12-dUTP-labeled chimeric oligonucleotides. Colonies hybridizing with the 935-A probe were identified only from cells transfected with the specific chimeric oligonucleotide; and there was no evidence of cross-hybridization. Conversion of G to A at nucleotide 935 occurred at an overall frequency of up to 11.9% and when corrected for transfection efficiency approached 43%. No other alterations were detected in the sequence of exon 6 with the targeted nucleotide exchange. These results show that a single base pair alteration in the alkaline phosphatase gene of HuH-7 cells can be introduced at a relatively high frequency following transfection with chimeric RNA/DNA oligonucleotides. This technique offers a novel and potentially powerful strategy for site-directed hepatic gene alteration without the use of viral-based vectors.
Improvement of the Marine Environmental Assessment for Dredging and Ocean Disposal of Coastal Sediment in Korea (2009)

We studied improvement in marine environmental impact assessment and related management systems of coastal sediments that are dredged inshore but disposed offshore. After reviewing and diagnosing the existing assessment procedures and problems, we recommend to design the core assessment items and improve the reliability of assessment byenhancing the quality assurance/quality control (QA/QC) and verification processes. We proposed eco-friendly disposal plan for dredging sediment such as reuse system in land development was explored. A marine environmental database system was established to support the assessment processes. Guidelines for marine research and modelling were proposed for improving assessment of dredging and disposal of coastal sediment. Also, applying of screening and scoping for marine environmental assessment was reviewed.
Organophosphorus chemistry. Part XIV. Reaction of phosphorodiamidous chlorides with sulphonamides: a new route to diazadiphosphetidines (1973)

Arenesulphonamides react with tetramethylphosphorodiamidous chloride, NN′-dimethyl-NN′-diphenylphosphorodiamidous chloride, and dimethylphosphoramidous dichloride, to give 1,3-bisarylsulphonyl-1,3,2,4-diazadiphosphetidines in high yields. The dimethyldiphenylphosphorodiamidous chloride also reacts with aniline in the presence of pyridine to give a diphenyldiazadiphosphetidine. but reacts with benzamide to give an N-benzoyltriaminophosphine. Some spectroscopic and chemical properties of the bisarylsulphonyldiazadiphosphetidines are described.
Embedding digital chronotherapy into bioelectronic medicines (2022)

Biological rhythms pervade physiology and pathophysiology across multiple timescales. Because of the limited sensing and algorithm capabilities of neuromodulation device technology to-date, insight into the influence of these rhythms on the efficacy of bioelectronic medicine has been infeasible. As the development of new devices begins to mitigate previous technology limitations, we propose that future devices should integrate chronobiological considerations in their control structures to maximize the benefits of neuromodulation therapy. We motivate this proposition with preliminary longitudinal data recorded from patients with Parkinson's disease and epilepsy during deep brain stimulation therapy, where periodic symptom biomarkers are synchronized to sub-daily, daily, and longer timescale rhythms. We suggest a physiological control structure for future bioelectronic devices that incorporates time-based adaptation of stimulation control, locked to patient-specific biological rhythms, as an adjunct to classical control methods and illustrate the concept with initial results from three of our recent case studies using chronotherapy-enabled prototypes.
[Cytokine therapy of metastatic renal cell carcinoma]. (1995)

Cytokine therapy of metastatic renal cell carcinoma reveals a remission rate of about 25% regarding to the different patients selection criteria, i.e. age, performance status, site of metastasis, tumour load. Remission is not correlated to patient's survival. Adjuvant or neoadjuvant immunotherapy is not a treatment option. Nephrectomy has no influence on distant metastases and should be limited to symptomatic primary tumours. In conclusion, cytokine therapy is not a standard treatment. Its value has to be evaluated in randomized trials.
Fatigue During Stretch-Shortening Cycle Exercises: Changes in Mechanical Performance of Human Skeletal Muscle (1987)

Stretch-shortening cycle (SSC), which is a normal contraction behavior of muscle, was used as a model to investigate muscular fatigue. Nine male volunteers were subjected to 100 repeated and exhaustive SSC contractions of the forearm extensors using a special sledge apparatus incorporating a force plate system. The fatigue contractions were performed on submaximal levels but the before-after comparison also included maximal drop-jump condition on the sledge as well as falls on to the floor. The results indicated that in the 100 submaximal SSCs the fatigue was characterized by increases in the contact times for both the eccentric and concentric phases of SSC, but the influence was more pronounced on the concentric part. The force-time curves during contact on the platform were influenced by fatigue so that the initial force peak became higher and the subsequent initial drop of force more pronounced. During submaximal and maximal drops, the angular velocities changed in the two phases of SSC. With progressing fatigue, the eccentric maximal angular velocity increased and the corresponding concentric velocities decreased. These changes were accompanied by slight changes in the elbow joint mechanism with respect to the contact, release, and maximal flexion angles. The results suggest that repeated SSC induces fatigue and the fatigue effects on the mechanical behavior of the muscle are very much similar to those induced by either isometric or concentric fatigue contractions. However, the transfer of the energy between eccentric and concentric phases was drastically reduced and this implies that SSCs can be used effectively to examine the fatiguability of the system regulating muscle stiffness during exercise.

Online QoS Prediction for Runtime Service Adaptation via Adaptive Matrix Factorization (2017)

Cloud applications built on service-oriented architectures generally integrate a number of component services to fulfill certain application logic. The changing cloud environment highlights the need for these applications to keep resilient against QoS variations of their component services so that end-to-end quality-of-service (QoS) can be guaranteed. Runtime service adaptation is a key technique to achieve this goal. To support timely and accurate adaptation decisions, effective and efficient QoS prediction is needed to obtain real-time QoS information of component services. However, current research has focused mostly on QoS prediction of working services that are being used by a cloud application, but little on predicting QoS values of candidate services that are equally important in determining optimal adaptation actions. In this paper, we propose an adaptive matrix factorization (namely AMF) approach to perform online QoS prediction for candidate services. AMF is inspired from the widely-used collaborative filtering techniques in recommender systems, but significantly extends the conventional matrix factorization model with new techniques of data transformation, online learning, and adaptive weights. Comprehensive experiments, as well as a case study, have been conducted based on a real-world QoS dataset of Web services (with over 40 million QoS records). The evaluation results demonstrate AMF's superiority in achieving accuracy, efficiency, and robustness, which are essential to enable optimal runtime service adaptation.
Interference-based optimal power-efficient access scheme for cognitive radio networks (2015)

In this paper, we propose a new optimization-based access strategy of multi-packet reception (MPR) channel for multiple secondary users (SUs) accessing the primary user (PU) spectrum. We devise an analytical model that realizes the multi-packet access strategy of the SUs. All the network receiving nodes have MPR capability. We aim at maximizing the throughput of the individual SUs subject to the PU's queue stability. Moreover, we are interested in providing an energy-efficient cognitive scheme. Therefore, we include energy constraints on the PU and SU average transmitted energy to the optimization problem. Each SU accesses the medium with certain probability that depends on the PU's activity, i.e., active or inactive. The numerical results show the advantage in terms of SU throughput of the proposed scheme over the conventional access scheme, where the SUs access the channel randomly with fixed power when the PU is sensed to be idle.
Biochemical characterization of an Fc gamma receptor purified from human neutrophils. (1988)

The Fc receptor identified by mAb 3G8 (Fc gamma RIII) was isolated by mAb affinity chromatography from 0.5 to 2 x 10(10) neutrophils yielding 33 to 149 micrograms of protein. Iodination of the purified protein identified a polypeptide of broad electrophoretic mobility from Mr 47 to 70 kDa and occasionally a fainter polypeptide at 100 to 130 kDa, which may be dimerized receptor. Two-dimensional isoelectric focusing gel electrophoresis illustrated multiple diffuse polypeptides ranging from a pI of less than 4.7 to 6.5. Treatment of the purified receptor with neuraminidase shifted the mobility of these polypeptides to a more basic pI, ranging from 6 to 8, illustrating the presence of sialic acid residues on Fc gamma RIII. The glycoprotein nature of Fc gamma RIII was characterized by several criteria. The receptor bound to Con A-Sepharose. Treatment of Fc gamma RIII with endoglycosidase H or F, which cleave high mannose and biantennary complex N-linked oligosaccharides, respectively, failed to alter the electrophoretic mobility of the Fc gamma R. Peptide N:glycosidase F, which cleaves all classes of N-linked oligosaccharides, reduced the Mr of Fc gamma RIII by 60% to reveal two poorly resolved polypeptides centered at Mr 25 kDa and ranging from Mr 16 to 28 kDa. Chemical deglycosylation with trifluoromethanesulfonic acid, which cleaves O- and N-linked oligosaccharides except for the asparagine-linked N-acetylglucosamine, reduced the Mr of Fc gamma RIII to 21 to 36 kDa. These results demonstrate that Fc gamma RIII is an acidic complex sialoglycoprotein and suggest that there may be 8 to 15 N-linked oligosaccharide chains on Fc gamma RIII.

Highly Selective Bimetallic Pt‐Cu/Mg(Al)O Catalysts for the Aqueous‐Phase Reforming of Glycerol (2012)

Abstract Monometallic Pt and bimetallic Pt‐Cu catalysts supported on Mg(Al)O mixed oxides, obtained by calcination of the corresponding layered double hydroxides (LDHs), were prepared and tested in the aqueous‐phase reforming (APR) of glycerol. The effect of the Mg/Al ratio and calcination temperature of the LDH support, as well as the effect of varying Pt and Cu amounts on glycerol reforming, was investigated. The use of a basic support increases the selectivity to hydrogen and the use of a Pt‐Cu bimetallic catalyst results in a decrease in alkane formation. The 0.9 wt. % Pt‐0.4 wt. % Cu/Mg(Al)O_2.95 catalyst system with an Mg(Al)O mixed oxide support obtained by the calcination of the corresponding LDH material with Mg/Al ratio of 2.95 at 673 K, showed higher hydrogen selectivity (55.3 %) and lower methane production (1.9 %) after 5 h reaction than the benchmark Pt/Al 2 O 3 catalyst (49.4 % and 5.6 %, respectively). Catalyst characterization by extended X‐ray absorption fine structure (EXAFS) spectroscopy showed a bimetallic interaction between Pt and Cu. The bimetallic interaction is thought to be responsible for the lowered methane formation and, ultimately, the high hydrogen selectivity observed.
