Abstract With the acceleration of the construction of quantum communication networks, scholars have proposed different quantum communication protocols for different application scenarios. However, few scholars pay attention to the risk assessment process before communication. In this paper, we propose a novel quantum risk assessment model based on quantum teleportation technology with two three-qubit GHZ states. Only by using Bell states measurements (BSMs) and two-qubit projective measurements (PJMs), the communicators can recovery any arbitrary two-qubit state. This protocol can transmit two-dimension risk assessment factors with better security performance. On the one hand, more sufficient evaluation factors allow… More >

Abstract Aims: This study aimed at providing an Italian short version of the ‘healthcare needs scale for youth with congenital heart disease’ (I-HNS-CHD-s), describing its construct validity and reliability. Methods: A multi-method and multi-phase design were adopted. Phase one referred to the cultural-linguistic validation of the original scale into Italian. Phase two tasted content and face validity of the Italian-translated scale. Phase three included the psychometric validation process of scale, encompassed two different steps: first cross-sectional data collection (sample A) purposed at determining the psychometric characteristics of the I-HNS-CHD-s, using an exploratory factor analysis (EFA). Then, a… More >

Abstract To detect security vulnerabilities in a web application, the security analyst must choose the best performance Security Analysis Static Tool (SAST) in terms of discovering the greatest number of security vulnerabilities as possible. To compare static analysis tools for web applications, an adapted benchmark to the vulnerability categories included in the known standard Open Web Application Security Project (OWASP) Top Ten project is required. The information of the security effectiveness of a commercial static analysis tool is not usually a publicly accessible research and the state of the art on static security tool analyzers shows… More >

Abstract Increased urbanization and industrialization have greatly contributed to the emission of higher amount of heavy metals such as cadmium, nickel, and lead into the environment. These metals are non-biodegradable and toxic, causing much effects on plants and by extension to animals and humans, which have become a major global concern. The inherent ability of plants to resist heavy metal toxicity seems to be the most sustainable and cost-effective strategy. Castor plant is widely studied due to its tolerance to the effects of heavy metal contaminated soils, owing to its large biomass content and high accumulating… More >

Abstract Adults with congenital heart disease (ACHD) constitute a growing population with complex cardiac physiopathology and frequent extra-cardiac involvement. The recent dramatic improvement of their life expectancy has resulted in an increasing proportion of ACHD patients requiring non-cardiac surgery. While a large body of evidence demonstrated the importance of an accurate risk assessment in patients with acquired heart disease before noncardiac surgery in order to reduce perioperative morbidity and mortality and detailed algorithms have been released by international societies, no specific guidelines are available for the perioperative management in this population. Nonetheless, understanding the complex anatomy… More >

Abstract Cognitive behavioural therapy (CBT) is a first-line psychotherapy in Western countries, yet there have been limited studies examined the required skills based on perception of CBT therapists in the context of Western countries, and there has been no such research in China. Currently, there is no exist of a selfassessment scale to evaluate the required competence perceived by CBT therapists in China. This study used both qualitative and quantitative method to develop a self-assessment tool by CBT therapist to provide their perception about required skills in the treatment of mental disorders in China. Qualitative research… More >

Abstract The assessment of the fairness of health resource allocation is an important part of the study for the fairness of social development. The data used in most of the existing assessment methods comes from statistical yearbooks or field survey sampling. These statistics are generally based on administrative areas and are difficult to support a fine-grained evaluation model. In response to these problems, the evaluation method proposed in this paper is based on the query statistics of the geographic grid of the target area, which are more accurate and efficient. Based on the query statistics of… More >

Abstract This paper addresses the problem of assessing and optimizing the acoustic positioning system for underwater target localization with range measurement. We present a new three-dimensional assessment model to evaluate the optimal geometric beacon formation whether meets user requirements. For mathematical tractability, it is assumed that the measurements of the range between the target and beacons are corrupted with white Gaussian noise with variance, which is distance-dependent. Then, the relationship between DOP parameters and positioning accuracy can be derived by adopting dilution of precision (DOP) parameters in the assessment model. In addition, the optimal geometric beacon… More >

Abstract Satellite networks have high requirements for security and data processing speed. In order to improve the reliability of the network, software-defined network (SDN) technology is introduced and a central controller is set in the network. Due to the characteristics of global perspective, control data separation, and centralized control of SDN, the idea of SDN is introduced to the design of the satellite network model. As a result, satellite nodes are only responsible for data transmission, while the maintenance of the links and the calculation of routes are implemented by the controller. For the massive LEO… More >

Abstract The traditional Range Doppler (RD) algorithm is unable to meet practical needs owing to the limit of resolution. The order of fractional Fourier Transform (FrFT) and the length of sampling signals affect SAR imaging performance when FrFT is applied to RD algorithm. To overcome the above shortcomings, the purpose of this paper is to propose a high-resolution SAR image algorithm by using the optimal order of FrFT and the sample length constraints for the range direction. The expression of the optimal order of SAR range signals via FrFT is deduced in detail. The initial sample More >
