SEROTYPING AND IDENTIFICATION OF CAMPYLOBACTER JEJUNI AND CAMPYLOBACTER COLI STRAINS OF HUMAN AND ANIMAL ORIGIN USING THE PCR METHOD

Steinhauserova I. , K. Fojtikova: Serotyping and Identification of Campylobacter jejuni and Campylobacter coli Strains of Human and Animal Origin Using the PCR Method. Acta Vet. Brno 1999, 68: 149–154. A total number of 178 strains of Campylobacter spp. from human patients suffering from diarrhea and from the intestinal content of slaughtered pigs and poultry was isolated during years 1996 to 1997. Campylobacter strains were isolated and identified by standard tests and the PCR method using fla A and fla B, as well. Isolates originating from human patients were identified as Campylobacter jejuni (98% = 108 strains) and C. coli (2% = 2 strains). Campylobacter spp. (20) strains obtained from slaughtered pigs were identified using standard tests in 45% (9 strains) and 40% (8 strains) as C. coli and C. jejuni, respectively. Strains of Campylobacter spp. (48) isolated from slaughtered poultry were identified as C. jejuni (89% = 42 strains). Standard tests failed to identify 9 strains; 6 strains were identified as Campylobacter jejuni and C. coli using the PCR method. Serotyping using 34 antisera of the Penner’s serotyping scheme was performed in 130 strains of Campylobacter jejuni isolated from poultry and human patients. This method was suitable for identification of almost 80% of C. jejuni strains. We found 10 different serotypes of human C. jejuni strains. There were serotypes (HS) 4, 1 and 9 (32%, 23% and 15%, respectively) predominating in the human population; they were followed by serotypes (HS) 10, 2 and 23 (8%, 5% and 3%, respectively). Animal strains included 7 (HS) serotypes. Like in the human strains, the serotype 4, found in 37% of examined isolates, was predominating. Serotypes 23 and 1 (17% and 15%, respectively) were the next most frequent ones. Comparing the obtained serotypes of human and animal strains we see that there are only 4 identical ones (i.e., 4, 1, 10, 23), which are, however, most frequently occurring in both groups of strains. The PCR methods and serotyping may facilitate and make more accurate the results of standard cultivation and in epidemiologically serious cases help in explaining the route of transmission.

Event-based planning and control for multi-robot coordination

A planning and control scheme for multi-robot coordination is presented. An event-based motion reference that drives the system to achieve the best possible coordination is introduced. The general task space is combined with the nonlinear feedback technique to design hybrid position/force controllers. To improve the force control performance, the dynamics of joint motors are taken into account. For a given task, a task projection operator can be found for each robot, with consideration of redundancy management. A distributed computing architecture is proposed for parallel implementation of this scheme. The event-based coordination scheme was experimentally implemented and tested for the coordinated control of two six-degree-of-freedom PUMA 560 robots with very good results. <<ETX>>
On evaluating the current distortion of the single-phase switch-mode rectifiers with current slope maps

This paper presents a simple way to evaluate the distortion level of the input current for single-phase switch-mode rectifiers (SMRs). Based on the possible conducting paths of various topologies of SMRs, slopes of the input and command currents are defined to form a slope map. By comparing the defined current slopes, the causes of current distortion are examined. Distorted waveforms of the input currents under hysteresis control are reviewed and classified into three types. Design criteria for the circuit parameters are also studied to reduce the current distortion level. Simulations and experiments are performed and the results show strong conformity to the theoretical analysis.
Predicting Heart Failure Patient Events by Exploiting Saliva and Breath Biomarkers Information

The aim of this work is to present a machine learning based method for the prediction of adverse events (mortality and relapses) in patients with heart failure (HF) by exploiting, for the first time, measurements of breath and saliva biomarkers (Tumor Necrosis Factor Alpha, Cortisol and Acetone). Data from 27 patients are used in the study and the prediction of adverse events is achieved with high accuracy (77%) using the Rotation Forest algorithm. As in the near future, biomarkers can be measured at home, together with other physiological data, the accurate prediction of adverse events on the basis of home based measurements can revolutionize HF management.
Role of Logic in Cognitive Science

Abstract In their work McCulloch and Pitts describe an idea of representing all of nervous activity in terms of propositional logic. This idea was quickly challenged. One of reasons for this challenge was rising believe that logic is unable to describe most of human cognitive processes. In this paper we will analyse premises of original McCulloch and Pitts proposition. Following that, we will ask about ability of symbolic (logical) systems to represent human cognition. We will finish by analysing relation between symbolic and subsymbolic computing, in hope of bridging the gap between the two.
SPATIAL AND TEMPORAL VARIATIONS IN THE TREMATODE COMPONENT COMMUNITY OF THE MUDSNAIL HYDROBIA VENTROSA IN RELATION TO THE OCCURRENCE OF WATERFOWL AS DEFINITIVE HOSTS

The component community of larval trematodes infecting the mudsnail Hydrobia ventrosa (Montagu) was examined in coastal lagoons of the southern Baltic Sea among different host subpopulations in relation to the structure of the waterfowl community. The 10 trematode species observed represent the families Notocotylidae (1), Echinostomatidae (1 or 2), Heterophyidae (2), Monorchidae (1), Microphallidae (3 or 4), Psilostomatidae (1), and Hemiuridae (1). Eight of these species infect waterfowl as adults. The structure of the trematode communities was similar between sampling sites. Seven trematode taxa were commonly found at all sampling sites. Prevalence values of the 6 most abundant taxa, which infect birds as final hosts, were significantly different between neither sampling sites nor across year. Overall trematode prevalence in H. ventrosa fluctuated seasonally. Prevalence usually peaked in summer between July and September or October. Low prevalences were observed in late winter and early spring. In contrast, the seasonal maximum in waterfowl numbers differed between areas because of significant spatial differences in the bird community structure. The species composition of the component trematode community of H. ventrosa in the coastal lagoons of the southern Baltic Sea is more or less independent of the species composition of the waterfowl community. This independence presumably results from the lack of host specificity in most of the observed trematode species. Otherwise, the low host specificity in combination with the enormous waterfowl diversity in the coastal lagoons might explain the stability of the prevalence pattern of the component trematode community.
Detoxification System in Spodoptera littoralis against Abamectin

Biochemical and histological analysis were performed on 4 larval instar of the cotton leaf worm Spodoptera littoralis to determine the effect of abamectin (LC50) on the biomarkers acetylcholinesterase (AChE), glutathione S-transferase (GST), α-, βesterase and mixed function oxidase (MFO). Biochemical analysis showed a severe reduction in the enzymatic activities of GST and α-esterase, as compared to the control, reaching their minimum activity at 4-day post-treatment. Therefore, abamectin may be not detoxified by these enzymes.Abamectin increase the enzyme activity of βesterase reaching its maximum activity at 4-day post-treatment. Abamectin treatment resulted in slightly reduction in MFO activity at 2and 6-day post-treatment, while it has no effect on the enzyme activity of AChE at all-time intervals, as compared with control. The natural bio-pesticideis being tested here with reference to insect hemocyte count (THC) and ultrastructure.Two days after treatment THC increased by 1.7-fold, whereas decreased after 4 and 6 days of application by 1.3 and 1.6-fold, respectively, as compared to untreated controls. Histological study on the S. littoralis larval hemocytes showed that abamectininduced pathological detrition. Electron dense granules, structured granules and desmosomes were synthesized. Also, large number of deformed mitochondria, autophagic lysosome and long pseudopodia were observed in hemocytes treated with abamectin. Finally, at late stage of infection cell organelles were completely lysed.
Exact Large Deviation Function in the Asymmetric Exclusion Process

By an extension of the Bethe ansatz method used by Gwa and Spohn, we obtain an exact expression for the large deviation function of the time averaged current for the fully asymmetric exclusion process in a ring containing $N$ sites and $p$ particles. Using this expression we easily recover the exact diffusion constant obtained earlier and calculate as well some higher cumulants. The distribution of the deviation $y$ of the average current is, in the limit $N \to \infty$, skew and decays like $\exp - (A y^{5/2})$ for $y \to + \infty$ and $\exp - (A' |y|^{3/2})$ for $y \to -\infty$. Surprisingly, the large deviation function has an expression very similar to the pressure (as a function of the density) of an ideal Bose or Fermi gas in $3d$.
The Denial of Death

The phenomenon of death in Western culture has been described by historians, anthropologists, writers and poets: Death is the greatest evil. "Gods so consider it," says Sapho, "else they would die. " And Anacreon is terrified by approaching death: "Death is too terrible. Frightening are the depth of Hades. There is no return. " Philosophers have through the centuries pursued the meaning of death. In early Greek writings, the Epicureans' argument against the fear of death speaks for itself: . For Epicurus life can be good, if only man will learn how to live and how to die. I have anticipated thee, Fortune, and entrenched myself against all thy secret attacks. And we will not give ourselves up as captives to thee or to any other circumstances: but when it is time for us to go. spitting contempt on life and on those who here vainly cling to it, we will leave life crying aloud in a glorious triumph song that we have lived well.

Facial individuality and expression analysis by eigenspace method based on class features or multiple discriminant analysis

This paper presents two methods for the analysis of facial individuality and expression; an eigenspace method based on class features (EMC) and multiple discriminant analysis (MDA). Those methods are used since they derive eigenvectors by which we may extract facial individuality or expression information from a given facial image. The facial individuality and expression analysis can be achieved by projecting the facial image onto the subspace spanned by a set of those eigenvectors. We apply EMC and MDA to the classification of facial images into 50 classes of individuals or into seven classes of facial expressions, and verify their effectiveness with some experimental results.
Two-Tone Phase Delay Control of Center Frequency and Bandwidth in Low-Noise-Amplifier RF Front Ends

This brief presents a two-tone system for controlling the center frequency and bandwidth of an RLC tank with an application to center frequency and bandwidth control in low noise amplifier (LNA) RF front ends. The circuit operates based on the fact that an RLC tank induces a phase difference with special properties between two frequencies. The system is demonstrated in hardware in the TSMC CMOS 0.18-μm process for a center frequency of 2.45 GHz and a bandwidth of 60 MHz. The LNA center frequency can be controlled with a precision of ≈0.2% while the bandwidth can be controlled with a precision of ≈8%. The tuning time is 3 μs multiplied by the number of tuning states. The tuning states are the circuit states set digitally and analyzed until the desired operating point is achieved.
An evaluation of life satisfaction after migration

Life satisfaction & immigration The study of the means by which humans create meaning and order out of life’s challenges and exigencies is very important. It is human nature to seek meaning in existence (Angrosino, 1995). Coping suggests an element of creativity as the individual needs to devise new and novel means to deal with problem situations which cannot always be met by well established habits or ready-made answers. Patterned ways of dealing with newness itself can be termed adjustment processes (Lazarus, 1969).
Impact of steady-state lopinavir plasma levels on plasma lipids and body composition after 24 weeks of lopinavir / ritonavircontaining ritonavircontaining ritonavircontaining therapy free of thymidine analogues

Results: Twenty-six patients were included. Plasma triglycerides (from 206 mg/dL to 261 mg/dL, P 5 0.09) and total cholesterol (from 201 to 206 mg/dL, P 5 0.03) increased from baseline to week 24. There was a significant rise in total fat (from 10.9 to 11.9 kg, P 5 0.02) and limb fat (from 3.8 to 4.4 kg, P 5 0.02) from baseline to week 24. We did not find any correlation between PK lopinavir levels and changes over time for triglycerides, cholesterol or body fat composition.
Thermal properties of SiC-ceramics substrate interface made by silver glass composition

In this work, thermal properties of Al<inf>2</inf>O<inf>3</inf>, AlN, SiC as well as some of SiC die attachment materials are characterized by the laser flash method. The thermal diffusivity, specific heat and thermal conductivity were measured or calculated for the systems consisted of Al<inf>2</inf>O<inf>3</inf> or AlN substrates and SiC structures with die-attach layers between them. The experiments for single materials were carried out within wide temperature range of 50°C ÷ 800°C in argon atmosphere. Firstly, the thermal diffusivity and conductivity of Al<inf>2</inf>O<inf>3</inf>, AlN and SiC bulk material were extracted to increase the final results accuracy within full temperature range. Then 8×8 mm<sup>2</sup> SiC chips were attached to 8×8 mm<sup>2</sup> Al<inf>2</inf>O<inf>3</inf> or AlN substrates by silver-glass composition. Thermal properties of SiC - ceramics connections were measured from room temperature up to 350°C. The connection quality was investigated by X-ray microtomography. The thermal conductivity of the interfacial silver glass composition between SiC and Al<inf>2</inf>O<inf>3</inf> decreases from 120 W/mK at room temperature to 45 W/mK at temperature of 350°C and between SiC and AlN from 270 W/mK to100 W/mK, respectively. These values strongly depend of interface quality and thickness of interfacial layer.
The Voltage-Dependent Deactivation of the KvAP Channel Involves the Breakage of Its S4 Helix

Voltage-gated potassium channels (Kv) allow ion permeation upon changes of the membrane electrostatic potential (Vm). Each subunit of these tetrameric channels is composed of six transmembrane helices, of which the anti-parallel helix bundle S1-S4 constitutes the voltage-sensor domain (VSD) and S5-S6 forms the pore domain. Here, using 82 molecular dynamics (MD) simulations involving 266 replicated VSDs, we report novel responses of the archaebacterial potassium channel KvAP to membrane polarization. We show that the S4 α-helix, which is straight in the experimental crystal structure solved under depolarized conditions (Vm ∼ 0), breaks into two segments when the cell membrane is hyperpolarized (Vm << 0), and reversibly forms a single straight helix following depolarization (Vm = 0). The outermost segment of S4 translates along the normal to the membrane, bringing new perspective to previously paradoxical accessibility experiments that were initially thought to imply the displacement of the whole VSD across the membrane. The novel model is applied through steered and unbiased MD simulations to the recently solved whole structure of KvAP. The simulations show that the resting state involves a re-orientation of the S5 α-helix by ∼ 5–6 degrees in respect to the normal of the bilayer, which could result in the constriction and closure of the selectivity filter. Our findings support the idea that the breakage of S4 under (hyper)polarization is a general feature of Kv channels with a non-swapped topology.
Evaluation and treatment of renal artery stenosis: impact on blood pressure and renal function

The conventional non-invasive tests to diagnose renal artery stenosis in a general hypertensive population are not accurate enough for screening purposes. Magnetic resonance angiography might become the new gold standard, with the advantages of the absence of contrast toxicity, good accuracy, and information on flow characteristics. With regard to the treatment of hypertension in patients with renal artery stenosis, intervention is advised only when blood pressure cannot be controlled by at least three antihypertensive drugs. Patency after stenting is superior to angioplasty, although its clinical benefit has not been proved. As for renal function, evidence - although from uncontrolled studies - for the preservation of renal function by intervention is accumulating, especially in those patients with bilateral stenosis or stenosis in a single functioning kidney.
System Dynamics Simulation of Energy Saving and Emission Reduction in Coal Mining Area

This paper established a system dynamics model of energy saving and emission reduction in coal mining area, as well as conducted simulation of different development plans, based on the analysis of energy saving and emission reduction factor of coal production links, of the complex structure of energy saving and emission reduction system in coal mining area, and of the dynamic feed-back mechanism inside the system. Result shows that total investment, coal production investment, environmental protection investment and coal energy consumptions per ton play an important part in the energy saving and emission reduction system in coal mining area. By adding total investment and refining the proportion between coal production investment and environmental protection investment, as well as reducing coal energy consumptions per ton, harmonious development of economic and energy saving and emission reduction could be achieved.
Urban Crime Risk Prediction Using Point of Interest Data

Geographical information systems have found successful applications to prediction and decision-making in several areas of vital importance to contemporary society. This article demonstrates how they can be combined with machine learning algorithms to create crime prediction models for urban areas. Selected point of interest (POI) layers from OpenStreetMap are used to derive attributes describing micro-areas, which are assigned crime risk classes based on police crime records. POI attributes then serve as input attributes for learning crime risk prediction models with classification learning algorithms. The experimental results obtained for four UK urban areas suggest that POI attributes have high predictive utility. Classification models using these attributes, without any form of location identification, exhibit good predictive performance when applied to new, previously unseen micro-areas. This makes them capable of crime risk prediction for newly developed or dynamically changing neighborhoods. The high dimensionality of the model input space can be considerably reduced without predictive performance loss by attribute selection or principal component analysis. Models trained on data from one area achieve a good level of prediction quality when applied to another area, which makes it possible to transfer or combine crime risk prediction models across different urban areas.
Prevalence and Correlates of Self-reported Nonadherence With Eye Drop Treatment: The Belgian Compliance Study in Ophthalmology (BCSO)

PurposeThis study aimed to investigate (1) the prevalence of nonadherence with eye drop treatment; (2) selected correlates of nonadherence at the patient and health-care organization level; and (3) the diagnostic value of the ophthalmologists' ratings, using patients' self-reports as standard. MethodsThis cross-sectional multicenter survey used questionnaires for ophthalmologists and their patients to assess self-reported nonadherence and its correlates. One item, using a 4-point scale [never (ie, adherent) to daily], asked the patients whether they had forgotten to administer eye drops during the past 2 weeks. Ophthalmologists rated their patients as adherent or nonadherent. Nonadherence was also determined by combined methods, whereby either could indicate nonadherence. Given the nested structure of the data, multilevel modeling was used to investigate self-reported nonadherence-correlates. Diagnostic values of ophthalmologists' report were calculated. ResultsOf 663 patients (48% female, 44% >69 years), nonadherence was indicated in 39.2% (n=260) through self-reporting, 2.1% (n=14) through ophthalmologists' ratings, and 40% (n=266) through combined measures. The multivariable, multilevel model showed following significant nonadherence-correlates: Male sex (P=0.01), younger age (P=0.027), and higher-dose frequency (P=0.001). No significant correlation with treating ophthalmologist (P=0.21) could be seen. Yet, the patients visiting their ophthalmologists at least every 3 months were less nonadherent than patients with fewer consultations (P=0.01). The ophthalmologists' report showed a sensitivity and specificity of 3% and 98.5%, respectively. ConclusionsThe prevalence of self-reported nonadherence was congruent with literature. The patients visiting their ophthalmologists at least every 3 months have a lower risk of nonadherence. Ophthalmologist report is an insensitive method for detecting nonadherence.
Flots de liens pour la modélisation d'interactions temporelles et application à l'analyse de trafic IP

Les interactions sont partout : il peut s'agir de contacts entre individus, d'emails, d'appels telephoniques, de trafic IP, d'achats en ligne, d'execution de code, etc. Les interactions peuvent etre dirigees, ponderees, enrichies d'informations supplementaires, cependant, dans tous les cas, une interaction signifie que deux entites u et v ont interagi du temps b au temps e : par exemple, deux individus u et v se rencontrent du temps b au temps e, deux machines sur un reseau demarrent une session IP du temps b au temps e, deux personnes u et v se telephonent du temps b au temps e, etc.Dans cette these, nous explorons une nouvelle approche visant a modeliser les interactions directement comme des flots de liens, c'est-a-dire des sequences de quadruplets (b,e,u,v) signifiant que u et v ont interagi du temps b au temps e. Nous posons les fondations du formalisme correspondant. Afin de valider notre travail theorique, nous nous concentrons sur l'analyse de trafic IP. Il est en effet crucial pour nous d'effectuer des aller-retours constants entre theorie et pratique : les cas pratiques doivent nourrir notre reflexion theorique, et, en retour, les outils formels doivent etre concus de facon a etre appliques de la maniere la plus generale.Nous appliquons notre formalisme a l'analyse de trafic IP, dans le but de valider la pertinence de notre formalisme for l'analyse de trafic IP, ainsi que comme methodologie de detection d'evenements. Nous elaborons une methode permettant d'identifier des evenements recouvrant plusieurs echelles de temps, et l'appliquons a une trace de trafic issue du jeu de donnees MAWI.
