The relationship between interleukin 33 promotes and lung inflammation in asthmatic children

Objective To study the expression of IL-33 in asthmatic children,and to investigate the effects of IL-33 on lung inflammation.Methods Thirty asthmatic children(asthma group) and 30 healthy as control(control group) were collected.Serum and induced sputum from the asthmatic children and control group were collected and the level of IL-33 in the samples was determined by enzyme linked immunosorbent assay(ELISA). The levels of IL-4,IL-5 and IL-13 in serum were also detected by ELISA.After treatment with inhalation of seretide(50/250) one month,the expression of IL-33,IL-4, IL-5 and IL-13 in serum were detected by ELISA again.Results IL-33,IL-4,IL-5 and IL-13 levels in serum of asthma group were significantly higher than that of control group(P 0.05 ). After treatment with inhalation of seretide(50/250) one month,the expression of IL-33,IL-4,IL-5 and IL-13 in serum of the asthmatic children were significantly decreased (P 0.05). Tight correlation between IL-33 and IL-4,IL-5 and IL-13 was identified(r =0.8926,r =0.8996,r = 0.9320,P 0.01). Conclusion It indicate that IL-33 is highly expressed in asthmatic children,and the highly expression of IL-33 was tightly correlation with inflammatory factors IL-4,IL-5 and IL-13,so that IL-33 can promote airway inflammation in asthmatic children.Thus presents a promising strategy for the treatment of asthma.

A linear equation based on signal increments to predict disruptive behaviours and the time to disruption on JET

This article describes the development of a generic disruption predictor that is also used as basic system to provide an estimation of the time to disruption at the alarm times. The mode lock signal normalised to the plasma current is used as input feature. The recognition of disruptive/non-disruptive behaviours is not based on a simple threshold of this quantity but on the evolution of the amplitudes between consecutive samples taken periodically. The separation frontier between plasma behaviours (disruptive/non-disruptive) is linear in such parameter space. The percentages of recognised and false alarms are 98% and 4%, respectively. The recognised alarms can be split into valid alarms (90%) and late detections (8%). The experimental distribution of warning times follows an exponential model with average warning time of 443 ms. On the other hand, the prediction of the time to the disruption has been fitted to a Weibull model that relates this predicted time to the distance of the points to the diagonal in the parameter space of consecutive samples. The model shows a very good agreement between predicted times and warning times in narrow time intervals (between 0.01 s and 0.06 s) before the disruption.
Nonparametric Spectral Analysis of Multivariate Time Series

Spectral analysis of multivariate time series has been an active field of methodological and applied statistics for the past 50 years. Since the success of the fast Fourier transform algorithm, the analysis of serial auto- and cross-correlation in the frequency domain has helped us to understand the dynamics in many serially correlated data without necessarily needing to develop complex parametric models. In this work, we give a nonexhaustive review of the mostly recent nonparametric methods of spectral analysis of multivariate time series, with an emphasis on model-based approaches. We try to give insights into a variety of complimentary approaches for standard and less standard situations (such as nonstationary, replicated, or high-dimensional time series), discuss estimation aspects (such as smoothing over frequency), and include some examples stemming from life science applications (such as brain data).

A Modified GMRES Method for Solving a Symmetric Solution to Lyapunov Equation for Multi-Agent Systems

: We consider solving a large-scale Lyapunov equation for a multi-agent system. As is well known, the Lyapunov equation can be solved by equivalently rewriting it as a system of linear equations. The di ﬃ culties in solving this system are memory requirement and computational complexity due to the large-scale coe ﬃ cient matrix involving a number of Kronecker products. This paper presents a modiﬁed GMRES method for solving the aforementioned system of linear equations taking account of its tensor structure and the symmetry of the unknown matrix in the Lyapunov equation. Through numerical experiments, the improvement in memory requirement and computational time by the present algorithms is veriﬁed in comparison with the previous GMRES-based methods.
The Interaction Between Concrete-Pictorial-Abstract (CPA) Approach and Elementary Students’ Self-Efficacy In Learning Mathematics

Abstract Driven by the elementary students’ low self-efficacy (SE) in learning mathematics, this study aims to delve deeper into the interaction between learning based on Mathematical Prior Ability (MPA) and the improvement of students' SE after the implementation of Concrete-Pictorial-Abstract (CPA) approach. In total, 119 elementary school students from Purwakarta, Subang, Karawang dan Bekasi participated. Both tests and non-tests were used as the instruments of this study. Using a quasi-experimental design with a nonequivalent pretest-posttest control group, a two-way ANOVA was used as the technical analysis of the data. The research results revealed that the learning factors are higher than 0.05 i.e. (0.235), the significance of the MPA factor is smaller than 0.05 i.e. (0.030), and the significance of the interaction factor (Learning MPA) is higher than 0.05 i.e. (0.301). It can be concluded that there is an interaction between learning (CPA and conventional) based on MPA and the students’ SE. Thus, the CPA approach can be used to enhance the students’ SE so that they can learn with higher confidence. Keywords : concrete pictorial abstract , self- e fficacy , mathematical prior ability.

Effects of Reynolds number on vortex structure behind a surface-mounted finite square cylinder with AR = 7

This paper presents the numerical solutions of flow around a surface-mounted square cylinder of aspect ratio h/d = 7 at Reynolds numbers of 652 and 13 041. The aim is to investigate the effect of the Reynolds number, between its medium-to-high range, on the flow and vortex structure around such a cylinder. The present simulations have successfully reproduced the primary flow, as well as the three-dimensional large-scale vortex structure in the wake of the finite wall-mounted body. The observation of base vortices, tip vortices, and a horseshoe vortex is consistent with previous experimental studies. A dipole wake is captured at the higher Reynolds number, while a quadrupole wake is captured for the lower, indicating that the Reynolds number strongly influences the wake structure. In the near-wake region, by plotting the isosurface of instantaneous second invariant of the velocity gradient, the full-loop structure is observed for the quadrupole wake, while the half-loop structure is observed for the dipole wake. In the far-wake region, a braided vortex structure formed by asymmetric hairpin vortices is observed at both Reynolds numbers and a new wake topology is proposed for flows with a similar geometry.This paper presents the numerical solutions of flow around a surface-mounted square cylinder of aspect ratio h/d = 7 at Reynolds numbers of 652 and 13 041.

Doppler Characterization in Ultra Wideband BAN Channels During Breathing

Monitoring the physical parameters from devices inside the body, using ultra wideband (UWB) technology, enables the development of high bandwidth demanding applications in real time. The relative movement of the nodes deployed in the body, due to breathing, can give rise to a frequency shifting effect, increasing the fading level in the propagation channel during transmissions. In this article, therefore, we present a study of the frequency effects on the propagation channel derived from the relative movement between two nodes of a wireless body area network (WBAN), at least one of them placed inside the human body, caused by breathing. The study is performed on the basis of the Doppler spectrum characterization in terms of the shape fitting and frequency spread parameter derivation. Continuous wave (CW) signals have been used to cover the UWB range at four selected frequencies: 3.1, 4.8, 6, and 8.5 GHz, and a liquid phantom has been employed for emulating the dielectric properties of the high water content tissues at the considered UWB frequencies.
Radio wave propagation simulation considering Doppler shift caused by other vehicles

: Generally, maximum Doppler frequency can be derived from velocity of moving vehicle. However, frequency shifts beyond the maximum Doppler frequency are observed in actual measurement. In this paper, Doppler shift is calculated in consideration with the shift caused by other moving vehicles. Numerical results show that the actual measured Doppler shift can be reproduced with high accuracy by considering the frequency shift at the other moving vehicles.
Negative Reactance Impacts Power Flow Convergence Using Conjugate Gradient Method

It is usually considered in power systems that the B matrices in fast decoupled power flow (B’ and B”) are symmetric and positive-definite. The fast decoupled power flow (FDPF) based on the conjugate gradient (CG) iterative method was well developed, because the CG iterative method has a good convergence property and a lower memory requirement which can be easily implemented in the parallel computation. However, a rare yet important phenomenon hasn’t been well addressed in that “negative reactance” may exist in the practical power system models, which could affect the definiteness of B matrices in FDPF and the CG convergence performance. In this brief, the eigenvalues of B matrices with negative reactance are investigated and the convergence of CG for FDPF is discussed. Several large-scale practical systems are tested, which could provide some insights for the study of the FDPF using the CG method with negative reactances.
On Empirical System Gramians

State‐space realizations of input‐output systems or control systems are a widely used class of models in engineering, physics, chemistry and biology. For the qualitative and quantitative classification of such systems, the system‐theoretic properties of reachability and observability are essential, which are encoded in so‐called system Gramian matrices. For linear systems these Gramians are computed as solutions to matrix equations, for nonlinear or parametric systems the data‐driven empirical system Gramians approximate the actual system Gramians. These empirical Gramians have manifold applications, for example in model reduction or decentralized control of nonlinear systems, as well as sensitivity analysis, parameter identification and combined state and parameter reduction of parametric systems. Here, we demonstrate that empirical system Gramians are also useful for linear but hyperbolic input‐output systems.
Two-pass two-way acceleration in a superconducting continuous wave linac to drive low jitter x-ray free electron lasers

We present a design study of an innovative scheme to generate high rep rate (MHz-class) GeV electron beams by adopting a two-pass two-way acceleration in a superconducting (SC) linac operated in continuous wave (CW) mode. The electron beam is accelerated twice by being reinjected in opposite direction of propagation into the linac after the first passage. Acceleration in opposite directions is accomplished thanks to standing waves supported in rf cavities. The task of recirculating the electron beam when it leaves the linac after first pass is performed by a bubble-shaped arc compressor composed by a sequence of double bend achromat. In this paper we address the main issues inherent to the two-pass acceleration process and the preservation of the electron beam quality parameters (emittance, energy spread, peak current) required to operate x-ray free electron lasers (FEL) with low jitters in the amplitude, spectral and temporal domain, as achieved by operating in seeding and/or oscillator mode a CW FEL up to 1 MHz rep rate. Detailed start-to-end simulations are shown to assess the capability of this new scheme to double the electron beam energy as well as to compress the electron bunch length from picoseconds down to tens of femtoseconds. The advantage of such a scheme is to halve the requested linac length for the same final electron beam energy, which is typically in the few GeV range, as needed to drive an x-ray FEL. The AC power to supply the cryogenic plant is also significantly reduced with respect to a conventional single-pass SC linac for the same final energy. We are reporting also x-ray FEL simulations for typical values of wavelengths of interest (in the 200 eV – 8 keV photon energy range) to better illustrate the potentiality of this new scheme.

The evaluation of serum cystatin C for early impaired renal function in patients with liver cirrhosis

Objective To investigate the diagnostic value of serum cystatin C(Cys C) for the detection of early impaired renal function in patients with liver cirrhosis. Methods The levels of serum creatinine(Cr),urea,creatinine clearance(Ccr),and Cys C in 67 patients with liver cirrhosis(patients divided group by sex,Child-Pugh scores or Ccr levels) and 32 healthy controls were mearsured. Results The levels of serum Ccr and Cys C in patients with liver cirrhosis were significantly different than in healthy controls(P(0.001)),but Cr and urea were not significantly different.The levels of serum Ccr,Cr,Cys C in patient with liver cirrhosis of different sex were significantly different than control group(P(0.05)～(0.001)),but urea was not significantly different.As patients with liver cirrhosis were divided into 3 groups by Child-Pugh scores,the levels of serum Ccr,Cr,urea and Cys C were significantly different than those in control group(P(0.05)～(0.001)). As patients with liver cirrhosis were divided into group Ⅰ and Ⅱ by Ccr=70 ml/min,the level of serum Cys C was higher than that in healthy control,and Cys C was higher in group Ⅱ than that in group Ⅰ(P(0.001)). Receiver operator characteristics(ROC) revealed a clear advantage of Cys C over Cr and urea. Conclusions Cr and urea cannot detect the moderately impaired renal function in patients with liver cirrhosis.Ccr was a early marker,but it overestimates diseases.Cys C can give an accurate diagnosis.Therefore,serum Cys C may be a potential marker for detection of early impaired renal function in patients with liver cirrhosis.
Acoustic-Structure Interaction in an Adaptive Helmholtz Resonator by Compliance and Constraint

The acoustic energy attenuation capabilities of traditional Helmholtz resonators are enhanced by various methods, including by coupled resonators, absorbing materials, or replacement of rigid walls with flexible structures. Drawing from these concepts to envision a new platform of adaptive Helmholtz resonator, this research studies an adaptive acoustic resonator with an internal compliant structural member. The interaction between the structure and acoustic domain is controlled by compression constraint. By applying uniaxial compression to the resonator, the flexible member may be buckled, which drastically tailors the acoustic-structure interaction mechanisms in the overall system. A phenomenological analytical model is formulated and experimentally validated to scrutinize these characteristics. It is found that the compression constraint may enhance damping capabilities of the resonator by adapting the acoustic-structure interaction between the resonator and the enclosure. The area ratio of the flexible member to the resonator opening and the ratio of the fundamental natural frequency of the flexible member to that of the enclosure are discovered to have a significant influence on the system behavior. These results reveal new avenues for acoustic resonator concepts exploiting compliant internal structures to tailor acoustic energy attenuation properties. [DOI: 10.1115/1.4045456]
Relative Docking and Formation Control via Range and Odometry Measurements

This article studies the problem of distance-based relative docking of a single robot and formation control of multirobot systems. In particular, an integrated localization and navigation scheme is proposed for a robot to navigate itself to a desired relative position with respect to a fixed landmark at an unknown position, where only range and odometry measurements are used. By carefully embedding historical measurements into equilibrium conditions, we design an integrated estimation-control scheme to achieve the relative docking asymptotically. It is rigorously proved that the robot will converge to the desired docking position asymptotically provided that control gains are chosen to satisfy certain conditions. This scheme is further extended to multirobot systems to consider an integrated relative localization and formation control problem. Unlike widely used spatial cooperation in the existing literature, we propose to exploit both spatial and temporal cooperations for achieving formation control. It is proved that multirobot formation can be achieved with zero error for directed acyclic graphs. Several simulation examples are provided to validate our theoretical results.
The influence of tip clearance and shape of pin fins on the heat transfer performance and friction factor in aluminum silicon alloy heat exchanger

Abstract In this article, the coupled heat transfer model was applied to investigate the effect of the tip clearance and shape of pin fins on the heat transfer performance and friction factor in the high temperature region of aluminum silicon alloy heat exchanger. The tip clearance ranged from 1 mm to 8 mm, and the shape of pin fins was the circular, drop-A and drop-B. The results showed that as the tip clearance increases, the outlet flue gas temperature increases, while the Nusselt number, the pressure loss and the friction factor decreases. For the circular pin fin, the difference of outlet flue gas temperature between it and drop-A was very slight, but both were higher than drop-B. In addition, circular pin fin had the minimum values of pressure loss friction factor. Comprehensively considering the heat transfer performance and friction factor, the thermo-hydraulic performance of circular pin fin with the tip clearance of 4 mm was superior to other cases.
