On the problem of linearization for state-dependent delay differential equations

The local stability of the equilibrium for a general class of statedependent delay equations of the form ẋ(t) = f ( xt, ∫ 0 −r0 dη(s)g(xt(−τ(xt) + s)) ) has been studied under natural and minimal hypotheses. In particular, it has been shown that generically the behavior of the state-dependent delay τ (except the value of τ) near an equilibrium has no effect on the stability, and that the local linearization method can be applied by treating the delay τ as a constant value at the equilibrium.

Active Regulation of Speed during a Simulated Low-Altitude Flight Task

This study examined active regulation of speed during a low-altitude flight task as a function of global optical flow rate, speed, and the presence or absence of a concurrent altitude disturbance. The results showed that altitude clearly had an impact on speed control. Control of speed was much more difficult when altitude disturbances were present. Even in the no altitude disturbance conditions, performance tended to be best at lower altitudes. Consistent with previous research, the results suggest that speed and altitude changes have additive effects on speed judgments. This is inconsistent with the simple global optical flow rate hypothesis that had suggested multiplicative effects. However, it is consistent with the general notion that judgments of self motion are based on properties of optical flow fields (i.e. angles and angular rates) that depend on distance and motion relative to textured surfaces.
Music Aggregators and Intermediation of the Digital Music Market

This article demonstrates that, contrary to popular belief, the advent of the Internet has not made intermediaries in the music market obsolete. Individual artists and independent record labels who want to sell their music in digital music stores must deliver their records via third-party companies called music aggregators. Drawing on the concepts of new institutional economics, the article demonstrates that the emergence of music aggregators is a market response to the high level of transaction costs and bargaining asymmetry associated with selling digital music online. The conclusion suggests that the major music conglomerates may seek ownership links with music aggregators, leading to the emergence of vertically integrated companies, which may have profound consequences for cultural markets.
Nierenarterienstenose und ischämische Nierenerkrankungen – eine Übersicht

Renal artery stenosis and ischemic kidney disease – a review. The spectrum of clinical presentation of patients with renal artery stenosis may differ widely, including asymptomatic patients in whom stenosis is detected by chance only, and flash pulmonary edema, a potentially life threatening syndrome. Further, renal failure may be the result of ischemic kidney disease. When renovascular hypertension was recog nized more frequently, and angioplasty and stent placement were established in renal artery stenosis, both diagnostic angiography and interventional therapy turned into widely used techniques. Lately only, larger studies were initiated that compared former non-interventional standard therapy or optimal medical therapy with angioplasty and stent. Three large studies (STAR, ASTRAL, CORAL) revealed disappointing results in terms of no clinically relevant or significant difference between medical and interventional treatment. Even serious and in part devastating side effects of interventional therapy including deaths were seen. The studies, however, have to be judged insufficient, especially because of patient selection. Many low-risk patients, with stenosis hemodynamically irrelevant were included, or the treating physician was not sure whether the patient would benefit from intervention. This review focuses on the clinical spectrum of presentation and describes the characteristic symptoms that should make one alert to suspect renovascular hypertension from renal artery stenosis. Pathogenesis and the diagnostic approach are discussed. Further, a critical review of studies is done. The circumstances are presented under which patients may eventually benefit from revascularization, weighing risks and benefit of the various treatment approaches. Finally, the conclusion is to “go back to the beginning”. Indeed, virtually all patients with atherosclerotic renal artery stenosis would have to be characterized exactly according to clinical and diagnostic presentation. Subsequently, all have to be included in carefully planned, prospective randomized trials comparing optimized medical therapy and revascularization. A sufficient longterm follow-up has to be performed focusing on hard endpoints like death, number and type of cardiovascular events, progression of renal failure and dialysis-dependence, and safety issues have to be evaluated carefully.

On the Numerical Simulation of Induced Anisotropy in Polar Ice

The aim of this work is to present a phenomenological constitutive flow model for polar ice derived from so-called mesoscopic considerations and its consistent implementation into an appropriate finite element scheme. A systematic investigation of the development of texture in isothermal polar ice is presented. From the viewpoint of numerics the flow of ice is considered as a stationary free surface Stokes flow fully coupled with the development of its texture. Boundary conditions at the free surface are accomodated in the course of the computation to the actual flow situation. It turned out that the choice of the velocity boundary conditions at the bottom (bed-rock) is the crucial point in modelling induced anisotropy of free surface flow.

Selected markers of oxidant challenge in essential hypertensive smokers

Aim: The study was set to assess the relationship between antioxidant status, smoking and hypertension, the argument being whether there would be a significant difference in antioxidant status and perhaps, a significant difference in blood pressure. Methods: A total of105 samples were collected. 36 samples were collected from type I hypertensive smokers; 47 from hypertensive non smokers, the remaining 22 were collected from normal non smokers, who served as control. The blood pressure of each subject was measured. Determinations of SOD activity and TBARS content were carried out on each of the samples. Determination of systolic and diastolic blood pressure was also carried out using a digital sphygmomanometer. The results of all investigations were thereafter subjected to statistical analysis using SPSS 17, the student’s t test being the tool of choice. Significance was tested at P<0.05. Results: The mean systolic and diastolic blood pressureof hypertensive smokers and non smokinghypertensives was found to be significantly increased. Similarly the mean systolic and diastolic blood pressure of hypertensive smokers was found to be significantly increased. SOD activity was significantly decreased while TBARS levels were significantly higher in both hypertensive groups. Lipid peroxidation was significantly higher while SOD activity was significantly lower in hypertensive smokers when compared with hypertensive non smokers Conclusion: It appears that cigarette smoking as a social lifestyle depletes SOD levels but increases lipid peroxidation. It also seems to favour the progression of essential hypertension from mild to severity. Keywords: Smoking, Hypertension, Reactive oxygen species, Antioxidant enzymes

Two Programs Educating the Public in Animal Learning and Behavior

Two educational programs have been developed that teach basic principles of animal learning and behavior and how they can be used in day to day interactions with companion animals. The first program educates violators of animal control laws about animal learning and cat and dog behavior to help them resolve their problems with their animals and avoid future animal control violations. The second educates home service providers concerning basic principles of animal communication, dog behavior, and the causes of aggression to help them avoid dog attacks on the job.
Antibacterial activity of essential oils of Seseli indicum a wild weed of family Apiaceae

The antibacterial activity of essential oils and their derivatives has been recognized for a long time. In the present study, the antibacterial properties of the essential oils obtained from the seeds of Seseli indicum, of Apiaceae family a wild weed found in the flood prone area of river Tapti, Gorakhpur (India). The essential oil obtained from seed was 3.4%. Essential oils were investigated for activity against Escherichia coli, Staphylococcus aureus and Bacillus subtilis using a punched-hole method. Essential oils inhibited all bacteria at both, low and high concentration. The results of this study confirmed the possibility of using Seseli indicum essential oils in broad spectrum antibacterial activities.
Neural response based speaker identification under noisy condition / Leyla Roohisefat

Speaker identification is the mechanism of determining a person among a set of speakers to certify whether that person is who he claims to be. The available speaker identification systems are mostly based on the acoustical signal itself. The problem is that they are very sensitive to noise and can work only at very high signal-to-noise ratio (SNR). However, neural responses are very robust against background noise. In this study, a wellknown model of the auditory periphery by Zilany and colleagues (J. Acous. Soc. Am., 2009) is employed to simulate the neural responses, known as neurogram, on identifying a speaker, and then average discharge rate or envelope (ENV) and the temporal fine structure (TFS) are computed from the neurogram. The resulted vectors are used to train the system by employing two types of classifiers, Gaussian Mixture Model (GMM) and Hidden Markov Model (HMM). The database consists of text-dependent speech samples from 39 speakers, and 10 speech samples were recorded for each speaker in a quiet room. The performance of the proposed method is compared with the traditional acoustic feature (mel-frequency-cepstral-coefficient, MFCC) based speaker identification method for both under quiet and noisy conditions. As the neural responses are robust to noise, the proposed neural response based system using TFS responses performs better than MFCC-based method, especially under noisy conditions. In general, GMM shows better accuracy for the proposed method than using HMM as a classifier.
Exponential Stability of Stochastic Systems with Delay and Poisson Jumps

This paper focuses on the model of a class of nonlinear stochastic delay systems with Poisson jumps based on Lyapunov stability theory, stochastic analysis, and inequality technique. The existence and uniqueness of the adapted solution to such systems are proved by applying the fixed point theorem. By constructing a Lyapunov function and using Doob’s martingale inequality and Borel-Cantelli lemma, sufficient conditions are given to establish the exponential stability in the mean square of such systems, and we prove that the exponentially stable in the mean square of such systems implies the almost surely exponentially stable. The obtained results show that if stochastic systems is exponentially stable and the time delay is sufficiently small, then the corresponding stochastic delay systems with Poisson jumps will remain exponentially stable, and time delay upper limit is solved by using the obtained results when the system is exponentially stable, and they are more easily verified and applied in practice.
Invasive mosquito species in Europe and Serbia, 1979 – 2011

People’s increased mobility and international trade play important roles in the dissemination of vectors and the pathogens that they could transmit. Climate change is likely to become another important consideration in the near future. The responses of insects to these changes (in addition to potential for increased vector capacity) could allow for a broadening of their colonized areas and the invasion of new sites. In the last couple of years a number of pathogen introductions into Europe have been recorded. The latest (Ravenna, Italy, 2007) was caused by the tropical Chikungunya virus, which is transmitted by the “Asian tiger mosquito”, a species introduced into Europe in 1979 (Albania), and then Italy in 1990. Invasion continued to France in 1999 and until present, Belgium, Montenegro, Greece, Switzerland, Croatia, Spain, Bosnia and Herzegovina, the Netherlands, Slovenia, Germany, Serbia, Bulgaria and Turkey have been invaded. Deciphering the true cause of changes in the distribution of mosquitoes is difficult and complex and depends, to a great extent, on the availability of data obtained by monitoring. In order to assist in vector-borne disease preparedness, distribution of the most important invasive species St. albopicta in Europe and particulars of findings in Serbia are conferred.
Molecular emission from GG Carinae's circumbinary disk

The appearance of the B[e] phenomenon in evolved massive stars such as B[e] supergiants is still a mystery. While these stars are generally found to have disks that are cool and dense enough for efficient molecule and dust condensation, the origin of the disk material is still unclear. We aim at studying the kinematics and origin of the disk in the eccentric binary system GG Car, whose primary component is proposed to be a B[e] supergiant. Based on medium- and high-resolution near-infrared spectra we analyzed the CO-band emission detected from GG Car. The complete CO-band structure delivers information on the density and temperature of the emitting region, and the detectable 13CO bands allow us to constrain the evolutionary phase. In addition, the kinematics of the CO gas can be extracted from the shape of the first 12CO band head. We find that the CO gas is located in a ring surrounding the eccentric binary system, and its kinematics agrees with Keplerian rotation with a velocity, projected to the line of sight, of (80\pm 1) km/s. The CO ring has a column density of (5\pm 3)x10^21 cm^-2 and a temperature of 3200\pm 500 K. In addition, the material is chemically enriched in 13CO, which agrees with the primary component being slightly evolved off the main sequence. We discuss two possible scenarios for the origin of the circumbinary disk: (i) non-conservative Roche lobe overflow, and (ii) the possibility that the progenitor of the primary component could have been a classical Be star. Neither can be firmly excluded, but for Roche lobe overflow to occur, a combination of stellar and orbital parameter extremawould be required.
Lead Transport in Soils Amended
with Municipal Solid Waste Ash

Municipal solid waste (MSW) is one of the major environmental problems in the Kingdom of Saudi Arabia (KSA). Many efforts have been made to reduce and recover MSW, but land disposal is still the most popular option. The current research aims to investigate the effects of municipal solid waste ash (MSWA) application rates on the mobility of Pb by 2 soils with their different physical and chemical properties. The soil was amended with MSWA at the rate of 0, 1, 2, 3, and 5% (w/w). Pb adsorption experiments were carried out by mixing 1.0 g of samples with initial Pb concentration varying from 0 to 300 mg L-1. The results indicated that distribution coefficient (Kd) values of Pb 2+ on sandy loam soil were higher than those on sandy loam soil. The application rate of 5% MSWA to loamy sand and sandy loam soils resulted in increases of Kd values by 36.6% and 29.0% more than the control soil (0%). MSWA amendment is most effective in reducing Pb mobility in the studied soils. The results suggest that MSWA could be used as a low-cost adsorbent for Pb2+ of contaminated soils.
Generic Attacks on Hash Functions by Jalaj

The subject of this thesis is a security property of hash functions, called chosen-targetforced-prefix preimage (CTFP) resistance and the generic attack on this property, called the herding attack. The study of CTFP resistance started when Kelsey-Kohno introduced a new data structure, called a diamond structure, in order to show the strength of a CTFP resistance property of a hash function. In this thesis, we concentrate on the complexity of the diamond structure and its application in the herding attack. We review the analysis done by Kelsey and Kohno and point out a subtle flaw in their analysis. We propose a correction of their analysis and based on our revised analysis, calculate the message complexity and the computational complexity of the generic attacks that are based on the diamond structure. As an application of the diamond structure on generic attacks, we propose a multiple herding attack on a special generalization of iterated hash functions, proposed by Nandi-Stinson.
Failure Envelope Detection in Structural Composite Systems Through Triboluminescent Sensor Arrays

As more composites are used for large-scale manufacturing in industries such as automotive, aerospace, naval engineering, and civil engineering, there is a corresponding need for more accurate and real-time information regarding any damage and deformation to these composite structures. One drawback of using composites as a structural entity is its brittle-type failure; caused by the nearly linear elastic nature of the stress-strain behavior. Damage in composites usually is barely visible (BVID). Visual inspections thus prove to be an ineffective tool to monitor composite damage. An effective non-destructive evaluation technique for damage monitoring of structural integrity thus becomes a critical aspect in maintenance. Real-time failure detection of FRP strengthened structures aims to reduce the response time and decision making involved in maintenance of deficient structures. The goal is thus to mimic a living organism’s ability to sense pain. One way in which this structural nervous system is being developed is through the utilization of the triboluminescence phenomenon. Triboluminescent materials contain crystal structures that emit light within visible spectrum when the crystals undergo elastic, plastic deformation, and even at fracture. This material property can be utilized for Structural Health Monitoring (SHM) in composites by embedding triboluminescent sensor wires. The light emitted by the triboluminescent material is transmitted through optical fibers and is utilized in detection of impact damage in a composite. By analyzing the way in which sensor nodes are activated by the impact damage propagation, it was determined that an optimal sensor wire configuration is 1 cm. This thesis contributes to the ongoing SHM research at the High-Performance Materials Institute (HPMI) by being the first research project to prove this method of embedding triboluminescent sensor wires in composites is capable of detecting delamination due to impact.
Lessons from the "Lexique actif du français"

The "Lexique actif du francais" (LAF) lexicographic project has just been completed. In its published form, the LAF contains the description of some 20,000 French semantic derivations and collocations. The theoretical and descriptive approach underlying the LAF is the Explanatory Combinatorial Lexicology, the lexicology branch of Meaning-Text linguistics. The main originality of this piece of work lies in the fact that the explanatory combinatorial formal approach has been interfaced, or popularized, in order to make the description accessible to non-linguists (mainly, language teachers and students). The aim of this paper is to offer a general presentation of the LAF, with special attention paid to how tensions generated by the dual need to rigorously describe lexical relations and to make accessible these descriptions to the layman have been handled. Two descriptive devices used in the LAF will be examined: the hierarchy of semantic labels and the metalinguistic formulas encoding lexical function relations.
An Electrooculographic Method for the Evaluation of Psychotropic Drugs on Saccadic Eye Movements in Healthy Subjects

Recording of saccadic eye movements has proved to be a valuable tool for investigation of brain function and dysfunction and is very sensitive to centrally acting drugs. Since there is a lack of agreement concerning velocity–amplitude characteristics of saccadic eye movements, the present study obtained saccadic eye movements from 24 healthy subjects using indigenously developed electro-oculographic recording and analysis system in forward and countdown sequence. The validity of the system was further tested by evaluating the psychotropic effects of 5mg zolpidem and 500mg caffeine in randomized, double blind, placebo controlled three way cross over design on 24 healthy subjects. Saccadic eye movements were measured at baseline and 1, 2 and 3 hrs after administration of study medication. Mean (±SD) values for peak saccadic velocity (PSV) over saccades of ±10, ±20, ±30, ±40, ±50 & ±60 degrees were in agreement with those previously reported. Zolpidem produced statistically significant decrease in PSV compared to placebo at all the angular displacements at 1 & 2 hrs. In contrast, caffeine produced non-significant increase in PSV at all angular displacements at 1hr. Similarly latency period (LP) increased with zolpidem and decreased with caffeine compared to placebo. The electro-oculographic recording and analysis system is simple, sensitive to centrally acting drug effects and therefore has potential for future experimental psychomotor assessment studies.
