Based on the research of a biological olfactory system, a novel chaotic neural network model - K set model has been es- tablished. This chaotic neural network not only simulates the real brain activity of an olfactory system, but also presents a novel chaotic concept for signal processing and pattern recognition. The characteristics of the K set models are investigated and show that a KIII model can be used for image pattern classification.

Childhood obesity has become a concern in most economically developing *** reasons for this seem clear:too much food and not enough *** dilemma has received much scientific attention,and the question arises:How do we get children to move and make good eating choices?In their opinion piece in this issue of the Journal of Sport and Health Science(JSHS),Ring-Dimitriou et al.1 make an argument that playing structured and supervised traditional sports will help children with obesity,where traditional sports include football,handball,gymnastics,athletics,and martial arts.

Muscle actions are typically divided into 3 categories：concentric,isometric,and *** active muscle that is shortening and produces positive mechanical work is said to work concentrically;an active muscle that is not changing its length,and thus does not produce net work,is said to work isometrically;and an active muscle that is elongated by external forces,and thus absorbs work,or produces negative work,is said to work eccentrically．

The use of terahertz time-domain spectroscopy(THz-TDS)for the nondestructive testing and evaluation(NDT&E)of materials and structural systems has attracted significant attention over the past two decades due to its superior spatial resolution and capabilities of detecting and characterizing defects and structural damage in non-conducting *** this study,the THz-TDS system is used to detect,localize and evaluate hidden multi-delamination defects(i.e.,a three-level multi-delamination system)in multilayered GFRP composite *** obtain accurate results,a wavelet shrinkage de-noising algorithm is used to remove the noise from the measured time-of-flight(TOF)*** thickness and location of each delamination defect in the z-direction(i.e.,through-the-thickness direction)are calculated from the de-noised TOF signals considering the interaction between the pulsed THz waves and the different interfaces in the GFRP composite laminates.A comparison between the actual and the measured thickness values of the delamination defects before and after the wavelet shrinkage denoising process indicates that the latter provides better results with less than 3.712%relative error,while the relative error of the non-de-noised signals reaches 16.388%.Also,the power and absorbance levels of the THz waves at every interface with different refractive indices in the GFRP composite laminates are evaluated based on analytical and experimental *** present study provides an adequate theoretical analysis that could help NDT&E specialists to estimate the maximum thickness of GFRP composite materials and/or structures with different interfaces that can be evaluated by the ***,the accuracy of the obtained results highlights the capabilities of the THz-TDS for the NDT&E of multilayered GFRP composite laminates.

AIM: To investigate the role of DNA-PKcs subunits inradiosensitization by hyperthermia on hepatocellularcarcinoma HepG2 cell ***: Hep G2 cells were exposed to hyperthermiaand irradiation. Hyperthermia was given at 45.5 ℃Cellsurvival was determined by an in vitro clonogenic assay forthe cells treated with or without hyperthermia at varioustime points. DNA DSB rejoining was measured usingasymmetric field inversion gel electrophoresis (AFIGE). TheDNA-PKcs activities were measured using DNA-PKcs enzymeassay ***: Hyperthermia can significantly enhanceirradiation-killing cells. Thermal enhancement ratio ascalculated at 10 % survival was 2.02. The difference inradiosensitivity between two treatment modes manifestedas a difference in the α components and the almost sameβ components, which α value was considerably higher inthe cells of combined radiation and hyperthermia ascompared with irradiating cells (1.07 Gy-1 versus 0.44 Gy1). Survival fraction showed 1 logarithm increase after an8-hour interval between heat and irradiation, whereas DNA-PKcs activity did not show any recovery. The cells wereexposed to heat 5 minutes only, DNA-PKcs activity wasinhibited at the nadir, even though the exposure time waslengthened. Whereas the ability of DNA DSB rejoining wasinhibited with the increase of the length of hyperthermictime. The repair kinetics of DNA DSB rejoining aftertreatment with Wortmannin is different from thehyperthermic group due to the striking high slow ***: Determination with the cell extracts andthe peptide phosphorylation assay, DNA-PKcs activity wasinactivated by heat treatment at 45.5 C, and could notrestore. Cell survival is not associated with the DNA-PKcsinactivity after heat. DNA-PKcs is not a unique factor affectingthe DNA DSB repair. This suggests that DNA-PKcs do notplay a crucial role in the enhancement of cellularradiosensitivity by hyperthermia.

From an economic point of view, the industrial econ- omy is efficient to overcome situations of a scarcity of goods. From a technological point of view, the resource efficiency of the manufacturing processes of the industrial economy has been per- manently improved during the last 200 years. In addition, cleaner processes have been developed. However, from an ecologic point of view, an increasing world population with increasing consump- tion has produced a "global footprint" which approaches the car- rying capacity of the planet. A circular economy and its high-value spin-offs-a lake economy and a performance or functional service economy-can fulfil customers' needs with considerably less resource consump- tion, less environmental impairment in production and considera- bly less end-of-life product waste, especially in situations of af- fluence, when a considerable stock of physical goods and infra- structures exists. Also, in situations of a scarcity of natural resources, both en- ergy and materials, often characterised by rapidly rising resource prices, the economic actors of a circular economy have a high competitive advantage over the actors of the industrial economy, due to much lower procurement costs for materials and energy. From a social point of view, a circular economy increases the number of skilled jobs in regional enterprises. However, the shift from a linear manufacturing economy to a circular or service economy means a change in economic thinking, from flow (throughput) management to stock (asset) management: in a manufacturing economy with largely unsaturated markets, total wealth increases through accumulation as resource through- put (flow) is transformed into a higher stock of goods of better quality (but in a manufacturing economy with largely saturated markets, wealth represented by the stock of goods will no longer increase); in a circular or service economy, total wealth increases through a smart management of existing physical assets (stock

Connected and automated vehicle(CAV) is a transformative technology that has great potential to change our daily life. Therefore, CAV related research has been advanced significantly in recent years. This paper does a comprehensive review on five selected subjects that lie in the heart of CAV research:(i) inter-CAV communications;(ii) security of CAVs;(iii) intersection control for CAVs;(iv) collision-free navigation of CAVs; and(v)pedestrian detection and protection. It is believed that these topics are essential to ensure the success of CAVs and need to be better understood. For inter-CAV communications, this paper focuses on both Dedicated Short Range Communications(DSRC) and the future 5 G cellular technologies; for security of CAVs, this paper discusses both passive and active attacks and the existing solutions; for intersection control, this paper summarizes the pros and cons of both centralized and decentralized approaches; for collision avoidance, this paper concentrates on four subareas: maneuverability, vehicle networking, control confliction, and motorcycles; for pedestrian detection, this paper covers sensor, radar, and computer vision based approaches. Under each topic, this paper not only shows the stateof-the-art, but also unveils potential future research directions. By establishing connections among these subjects, this paper shows how they interact with each other and how they can be integrated into a seamless user experience. It is believed that the literature covered and conclusions drawn in this paper are very helpful to CAV researchers, application engineers, and policy makers.
