reatment of Calcific Aortic tenosis With the Percutaneous Heart Valve

OBJECTIVES The aim of this work was to study the feasibility, safety, efficacy, and durability of percutaneous heart valve (PHV) implantation in the aortic position. BACKGROUND We developed a PHV (equine pericardium valve in a balloon-expandable, stainless-steel stent) to treat patients with inoperable aortic stenosis (AS). METHODS Thirty-six patients (aortic valve area 0.7 cm, New York Heart Association [NYHA] functional class IV, and severe comorbidities), formally declined for surgery, were recruited on a compassionate basis. The PHV was implanted by retrograde or antegrade trans-septal approach. Clinical and echocardiographic outcomes were assessed serially. RESULTS Twenty-seven patients were implanted successfully (23 antegrade, 4 retrograde) in the subcoronary position with improvement in valve area (0.60 0.11 cm to 1.70 0.10 cm, p 0.0001) and transvalvular gradient (37 13 mm Hg to 9 2 mm Hg, p 0.0001). Paravalvular aortic regurgitation was grade 0 to 1 (n 10), grade 2 (n 12), and grade 3 (n 5). One week post-procedure, improvement in left ventricular function (45 18% to 53 14%, p 0.02) was most pronounced in patients with ejection fraction 50% (35 10% to 50 16%, p 0.0001). Thirty-day major adverse events after successful implantation were 26% (pericardial tamponade, stroke, arrhythmia, urosepsis, and one death unexplained at autopsy). Eleven patients are currently alive with follow-up of 9 months (n 2), 10 months (n 3), 11 months (n 1), 12 months (n 2), 23 months (n 1), and 26 months (n 2). All patients experienced amelioration of symptoms ( 90% NYHA functional class I to II). Percutaneous heart valve function remained unchanged during follow-up, and no deaths were device-related. CONCLUSIONS Percutaneous heart valve implantation is feasible in inoperable patients with end-stage AS leading to hemodynamic and clinical improvement. Continued advances and improved patient selection should decrease adverse events in the near future. (J Am Coll Cardiol ublished by Elsevier Inc. doi:10.1016/j.jacc. 2006.01. 049
Behavioral Counseling with Systematic Desensitization Techniques to Reduce Anxiety : Development of Counseling Guidelines

This study aims to determine the acceptance (acceptedbillity) of behavioral counseling guides with systematic desensitization techniques to reduce student anxiety. This guide is an instrument for BK teachers in providing counseling guidance services in schools. The development procedure in this study follows the 4D development model which is limited only to content validation testing. There are five guidance and counseling experts and practitioners who have tested the feasibility of this guide. The instrument used for the assessment consisted of 25 items that referred to the acceptance of the handbook. Analysis of the results of the assessment uses the formulation of the content validity ratio calculation from Lawshe. The results of the analysis show that the validation of the cognitive behavioral counseling manual has a content validity index (CVI) of 0.95, which means very good or special. meet the eligibility criteria to be used as an instrument in carrying out counseling guidance services.
Neue Möglichkeiten einer optimalen Insulintherapie

Die Problematik einer optimalen Insulintherapie geht aus der Vielzahl der heute verwandten Präparate hervor. Die AltInsuline haben ihr eng begrenztes Anwendungsgebiet. Von ihnen benötigt man zur Erreichung einer optimalen Einstellung häufigere Injektionen am Tage. Die Idee der ,,Depot-Insuline" istfast so alt wie das Insulin selbst. Schon 1925 untersuchte Bertram (1) die Wirkung des an Olivenöl und an Eiweißkörper gekoppelten Insulins. Er bewies, daß die Insulinwirkung aUf die Blutzuckerkurve im umgekehrten Verhältnis zur Schnelligkeit der Resorption steht (2). Große Vorteile bietet die Behandlung mit Misch-Insulinen. Bei der Mehrzahl der Zuckerkranken müssen davon aber 2 Injektionen am Tage vorgenommen werden. Dem idealen Ziel der Diabetesbehandlung, mit e i n e r Injektion am Tage auszukommen, ist man in den letzten Jahren durch die Entdeckung modifizierter Insuline näher gekommen. Erst kürzlich wurden die Wege und Irrwege der deutschen Insulinforschung dargelegt (8). Z ü 1 z e r hatte bereits 1908 also 12 Jahre vor B a n tin g und B e s t das Insulin in Händen. Nebenwirkungen in Form des damals noch unbekannten Insulinschocks verhinderten seine praktische Anwendung. Erst die Möglichkeiten fortlaufender Blutzudcerbestimmungen ließen die therapeutische Wirksamkeit erkennen. 1936 gelang H a g e d o r n und Mitarbeitern die Herstellung eines klinisch wirksamen Depot-Insulins. Sie verwandten als Resorptionsverzögerer das Protamin, einen Eiweißkörper aus dem Sperma der Regenbogenforelle. S c o t t und Fi s h e r (32) sowie K e r und Mitarbeiter (18) zeigten, daß Zinkzusatz zum Protamin die Wirkung verstärkte. 1936 führte Um b e r (38) das von D ö r z b a ch aufgefundene Surfen-Insulin in die Therapie ein. Es zeigte eine gute Verzögerungswirkung, die aber darin lag für viele Fälle ein Vorteil früher einsetzte als die des Zink-Protamin-Insulins. Uber die bei den Depot-Insulinen zu verwendenden höchsten Einzeldosen herrschten anfangs verschiedene Meinungen. Von manchen Autoren wurden bis zu 80 E in einer Spritze gegeben. Die dadurch bedingten Gefahren der Schockwirkung führten Bertram, Denning, Dienst, Lietzner u. a. (3) dazu, als höchste Dosis 40-50 E anzugeben. Bei der früher mit relativ kohlenhydratarmen und fettreichen Diäten geübten Therapie gelang es, einen größeren Teil der mittelschweren Zudierkranken auf e j n e morgendliche Injektion einzustellen. In schweren Fällen wurden zwei Injektionen benötigt. Heute ist man auf Grund der Erfahrungen der Kriegsund Hungerjahre dazu übergegangen, die Ernährung der Zuckerkranken weitgehend derjenigen stoffwechselgesunder Menschen anzupassen. Diese Lockerung der Diät ist nur unter 3 Bedingungen möglich: 1. Reine Kohlenhydrate müssen vermieden werden. 2. Die Diät muß fettarm sein (Normalgewichtige erhalten 70 g, Adipöse nur 40 g Fett). 3. Die erlaubte Kohlenhydratmenge (200-350 g) muß in 6 Mahlzeiten über den Tag verteilt werden (B e r t r a m) (6). Diesen Maßnahmen muß die Insulinbehandlung angepaßt werden.
Response spectra analysis of the modal summation technique verified by observed seismometer and accelerometer waveform data of the M6.5 Pidie Jaya Earthquake

Wave vibration confined in the boundary will produce stationary wave solution in discrete states called modes. There are many physics applications related to modal solutions such as air column resonance, string vibration, and emission spectrum of the atomic Hydrogen. Naturally, energy is distributed in several modes so that the complete calculation is obtained from the sum of the whole modes called modal summation. The modal summation technique was applied to simulate the surface wave propagation above crustal structure of the earth. The method is computational because it uses 1D structural model which is not necessary to calculate the overall wave propagation. The simulation results of the magnitude 6.5 Pidie Jaya earthquake show the response spectral of the Summation Technique has a good correlation to the observed seismometer and accelerometer waveform data, especially at the KCSI (Kotacane) station. On the other hand, at the LASI (Langsa) station shows the modal simulation result of response is relatively lower than observation. The lower value of the reaction spectral estimation is obtained because the station is located in the thick sedimentary basin causing the amplification effect. This is the limitation of modal summation technique, and therefore it should be combined with different finite simulation on the 2D local structural model of the basin.
Identifying the Sources of Convective Memory in Cloud-Resolving Simulations

Convection is often assumed to be controlled by the simultaneous environmental fields. But to what extent does it also remember its past behavior? This study proposes a new framework in which the memory of previous convective-scale behavior, “microstate memory,” is distinguished from macrostate memory, and conducts numerical experiments to reveal these memory types. A suite of idealized, cloud-resolving radiative–convective equilibrium simulations in a 200-km square domain is performed with the Weather Research and Forecasting (WRF) Model. Three deep convective cases are analyzed: unorganized, organized by low-level wind shear, and self-aggregated. The systematic responses to sudden horizontal homogenization of various fields, in various atmospheric layers, designed to eliminate their specific microstructure, are compared in terms of precipitation change and time of recovery to equilibrium. Results imply a substantial role for microstate memory. Across organization types, microstructure in water vapor and temperature has a larger and longer-lasting effect on convection than in winds or hydrometeors. Microstructure in the subcloud layer or the shallow cloud layer has more impact than in the free troposphere. The recovery time scale dramatically increases from unorganized (2–3 h) to organized cases (24 h or more). Longer-time-scale adjustments also occur and appear to involve both small-scale structures and domain-mean fields. These results indicate that most convective microstate memory is stored in low-level thermodynamic structures, potentially involving cold pools and hot thermals. This memory appears strongly enhanced by convective organization. Implications of these results for parameterizing convection are discussed.
New results in applying the machine learning to GRB redshift estimation

Gamma-ray bursts (GRBs) are the most energetic transients in the far Universe. Several thousands of GRBs have been observed so far but we could measure the distance of only a few hundreds. We studied the parameters of GRBs with available spectroscopic redshift in order to be able to estimate the redshift of those GRBs without a measured one. To calculate their distances we applied two machine-learning estimator methods: random forest regressor and XGBoost. For the process we used selected gamma, x-ray and ultraviolet parameters from the Swift GRB catalog, which contains the measured spectroscopic redshift of 328 GRBs. We found a significantly higher correlation between the measured and estimated redshift, we have improved the correlation in multiple steps from 0.57 (published by Ukwatta et al., 2016) to 0.67. It seems that both the random forest and the XGBoost methods give similarly high correlation. For further improvements additional redshift measurements are required.
Modeling roughness perception for sounds with ramped and damped temporal envelopes

Roughness is considered to be an important perceptual attribute contributing to overall sound quality. Starting with the work by Vogel, a number of models have been developed to compute the roughness of arbitrary sounds. They consist of a ﬁrst stage modeling transformations in the peripheral hearing system and a central part in which the envelopes within each auditory ﬁlter are analyzed for their speciﬁc roughness contributions. These modern implementations, e.g. the one by Daniel and Weber, all have the limitation that they are not sensitive to the phase of the envelope. Speciﬁcally, a sound with a nonsymmetrical envelope will receive the same roughness value as its time inverse. Since psychoacoustical data by Pressnitzer and McAdams show a clear difference in perceived roughness for such sounds, we present here extensions to roughness algorithms that are sensitive to the phase of the temporal envelopes. Compared with other implementations, we tested the possible contributions of two speciﬁc elements: a compressive gammachirp model for the inner ear, and a variety of hair cell models or black-box stages developed to model adaptation processes. While the gammachirp model in our implementation contributes little to the differences in perceived roughness, all variants of the "hair-cell models" introduced a higher roughness value for sounds with a damped envelope (fast onset, slow decay) than for a ramped envelope (slow onset, fast decay). For the hair cell models the predicted differences were too low, for the black-box model of adaptation they were too high. The implications of such an approach for predicting the roughness for a wider set of perceptual data will be discussed.
A study on 2 and 3-piecewise functions compared with some growth models

For growth models, in addition to some classical growth mode ls, general formations of 2 and 3 piecewise functions were given with their parameters. For finding a good model of the le ngth of the tree, Eucalyptus camaldulensis Dehn. , in addition to several sigmoidal functions (Logistic, Brody, Korkmaz-Uckardes, Gompertz, and Von Bertalanffy), 2 and 3-piecewise function s were given with their parameters. They are compared by using error sum o f squares criteria. According to this criteria, it was seen t hat piecewise functions have minimum error sum of squares according to cla ssic l growth models used in this study. Especially it was se en that error sum of squares of 3-piecewise function has the most min imum value. For that reason, using of piecewise functions in addition to classical growth models in their studies on growth data was s uggested to the researchers using growth models in their stu die .
Determining the observer parameters for back EMF estimation for selected types of electrical motors

In the paper a procedure for determining the observer parameters for selected types of electrical motors is discussed. The procedure is based on the identity observer developed by Luenberger. The paper presents determining the parameters using calculation examples for the DC motor and also for the permanent magnet synchronous motor (PMSM), which utilize the extended state vector to estimate the back electromotive force (BEMF). Presented observer for PMSM doesn’t need to use the information about load torque. The main task of this study is to show how to utilize these general theory to a specified type of motors. Such procedure avoids the use of time-consuming methods of the parameters selection, which are based on random algorithms or the computational intelligence.
Skill Evaluation of Extended-Range Forecasts of Rainfall and Temperature over the Meteorological Subdivisions of India

Under the National Monsoon Mission Project initiated by the government of India’s Ministry of Earth Sciences, an indigenous dynamical ensemble prediction system (EPS) has been developed at the Indian Institute of Tropical Meteorology based on the state-of-the-art Climate Forecast System Model version 2 (CFSv2) coupled model, for extended-range (~15–20 days in advance) prediction. The forecasts are generated for the entire year covering the southwest monsoon, the northeast monsoon, and the summer and winter seasons. As the forecast of rainfall is important during the southwest and northeast monsoon seasons, along with that of the temperature during the summer and winter seasons, the present study documents the deterministic as well as probabilistic skill of the EPS in predicting the results in the respective seasons, over various meteorological subdivisions throughout India, on a pentad-lead time scale. The EPS is found to be skillful in predicting rainfall during the southwest and northeast monsoon seasons, as well as temperature during the summer and winter seasons, across different subdivisions of India. In addition, the EPS is noted to be skillful in predicting selected extremes in rainfall and temperature. This affirms the reliability and usefulness of the present EPS from an operational perspective.

Adaptive Variant of the BUS approach to Bayesian Updating

The BUS approach is a recently proposed method [1] for Bayesian updating of models with structural reliability techniques. Especially for high-dimensional problems, the combination of BUS with subset simulation [2] is shown to be efficient in drawing samples from the posterior distribution. The BUS approach can be considered an extension of rejection sampling, where a standard uniform random variable is added to the space of random variables. Each generated sample from this extended random variable space is accepted if the sample of the uniform random variable is smaller than the likelihood function scaled by a constant c. The constant c has to be selected such that it’s reciprocal is not smaller than the maximum of the likelihood function. For 1/c considerably larger than the maximum of the likelihood function, the efficiency of the approach decreases. However, in many cases the maximum of the likelihood function is not known in advance. In this contribution, we propose a technique for adaptively selecting the parameter c. This causes the rejection/acceptance criterion to change throughout the simulation. The proposed approach is compared to the TMCMC method proposed by Ching and Chen in [3] by means of a numerical example. We show that the proposed approach maintains the efficiency of BUS for problems with many random variables.

FePt3 nanosuspension synthesized from different precursors – a morphological comparison by SAXS, DLS and TEM

Annealed iron-platinum (FePt) is ferromagnetic in a nanoscale regime which is necessary for energy and data storage, whereas the as-synthesized form of FePt-based nanoparticles exhibits superparamagnetism useful for biomedical applications. In this study, as-synthesized nanosuspensions from the reaction of Pt(acac) 2 with Fe(acac) 3 and Fe(hfac) 3 are compared. X-ray diffraction (XRD) peaks for both samples are assigned to the FePt 3 phase. As shown by transmission electron microscopy (TEM) and small angle X-ray scattering (SAXS), nanoparticles synthesized by using Fe(acac) 3 have a smaller average diameter, but larger polydispersity index and particle agglomerations. On the other hand, the nanoparticles synthesized by using Fe(hfac) 3 can self-assemble into a longer range of patterned monolayer. Dynamic light scattering (DLS), measuring the size of cluster of nanoparticles as well as oleic acid and oleylamine at their surface, confirms that larger agglomerations in the sample were synthesized by using Fe(acac) 3 . In addition to the size distribution, magnetic properties were influenced by the composition of these nanoparticles.
A generation of 2 μm Q-switched thulium-doped fibre laser based on anatase titanium(IV) oxide film saturable absorber

Abstract We demonstrate a Q-switched thulium-doped fibre laser operating at approximately 1935 nm wavelength using anatase titanium(IV) oxide (TiO2) embedded in polyvinyl alcohol as the passive newly saturable absorber (SA). The film has absorption loss of 3.5 dB and modulation depth of 33%. It is sandwiched between two fibre ferrules in a ring laser cavity to produce self-started pulse train with a repetition rate that is tuned from 30.12 to 36.96 kHz as the 1552-nm pump power is increased from 289 to 485 mW. At maximum pump power, the laser produced a Q-switching pulse train with pulse duration, output power, pulse energy and peak power of 1.91 μs, 11 mW, 0.3 μJ and 146 mW, respectively. These results show that the TiO2 is a new potential SA material for pulsed laser applications.
On Finite Sums of Good and Shar that Involve Reciprocals of Fibonacci Numbers

Recently Nathaniel Shar presented a finite sum, involving the Fibonacci numbers, that generalizes a classical result first considered by I. J. Good and others. In this paper we provide a generalization of Shar’s sum. Furthermore, we give an analogue for the Lucas numbers. Finally we note that our generalization of Shar’s sum and its analogue for the Lucas numbers carry over to certain one parameter generalizations of the Fibonacci and Lucas numbers.
Observer-based non-linear H ∞ attitude control for a flexible satellite

This study focuses on the observer-based non-linear H ∞ (OBNH) attitude control for a flexible satellite with external disturbances and local state-region constraints. By considering the structural features of the attitude system and applying Lyapunov stability theory, the solvable conditions of the OBNH attitude control problem are provided. An advantage of this study is that the state-feedback controller and the reduced-order state observer can be designed independently, thus significantly reducing the complexity of the attitude control algorithm. Furthermore, based on the polynomial sum of squares (SOSs) and the generalised S-procedure techniques, the above problem can be transformed into a convex optimisation problem with SOS constraints. This conversion can effectively overcome the computational difficulties widely present in the control problem of non-linear systems. Finally, a numerical example is given to illustrate the effectiveness and feasibility of the proposed approach.
Catch-up of Chinese Engineering Technical Standards from the Perspective of Cognitive Legitimacy

In recent years, Chinaâ€™s engineering construction has advanced by leaps and bounds and made great achievements in the world. However, at present, China's engineering technical standards in overseas projects are often faced with the situation of low cognitive legitimacy. The significance of this study is to help Chinese engineering technical standards catch up with the cognitive legitimacy in overseas projects. This study explains the meaning of cognitive legitimacy of engineering standard by using Neuroscience and the method of empirical research, and thus proves that standardization and standard flexibility directly affect cognitive legitimacy of engineering standard, and psychological distance plays a role of adjusting variables. It not only theoretically introduces the method of Neuroscience into the study of cognitive legitimacy and fills the theoretical deficiency in the field of catching up of cognitive legitimacy, but also practically provides guidance for the pursuit of cognitive legitimacy of Chinese engineering technical standards in overseas projects.
