Yolk vitamin E positively affects prenatal growth but not oxidative status in yellow-legged gull embryos

Current Zoology 2018年第3期64卷 285-292页

Parental effects occur whenever the phenotype of parents or the environment that they experience influences the phenotype and fitness of their offspring, In birds, parental effects are often mediated by the size and biochemical quality of the eggs in terms of maternally transferred components. Exogenous antioxidants are key egg components that accomplish crucial physiological functions during early life. Among these, vitamin E plays a vital role during prenatal development when the intense metabolism accompanying rapid embryo growth results in overproduction of pro-oxidant molecules. Studies of captive birds have demonstrated the positive effect of vitamin E supplementation on diverse phenotypic traits of hatchling and adult individuals, but its effects on embryo phenotype has never been investigated neither in captivity nor under a natural selection regime. In the present study, we experimentally tested the effect of the in ovo supplementation of vitamin E on morphological traits and oxidative status of yellow-legged gull （Larus michahellis） embryos. The supplementation of vitamin E promoted somatic growth in embryos soon before hatching, but did not affect their oxidative status. Our results suggest that maternally transferred vitamin E concentrations are optimized to prevent imbalances of oxidative status and the consequent raise of oxidative damage in yellow-legged gull embryos during prenatal development.

Structural health monitoring of asphalt pavements using smart sensor networks: A comprehensive review

引用

Journal of Traffic and Transportation Engineering(English Edition) 2020年第5期7卷 639-651页

作者： Alessandro Di graziano Vincenzo Marchetta Salvatore Cafiso Department of Civil Engineering and Architecture University of CataniaCatania 95225Italy

Early, effective and continuous monitoring allows to reduce costs and to extend life of road infrastructure. For this reason, over the years, more and more efforts have been made to implement more advanced and effective monitoring systems at ever more contained costs,going from impractical manual and destructive methods through automated in vehicle equipment to the most recent wireless sensor network(WSN) embedded into the pavement. The purpose of this paper is to provide a comprehensive, up-to-date critical literature review of wireless sensor networks for pavement health monitoring, considering, also,the experience gained for wired sensor as fundamental point of reference. This work presents both the methodology used to collect and analyse the current bibliography and provides a description and comments fundamental characteristics of wireless sensor networks for pavement monitoring for damage detection purposes, among which energy supply, the detection method, the hardware and network architecture and the performance validation procedures. A brief analysis of other possible complementary applications of smart sensor networks, such as traffic and surface condition monitoring, is provided. Finally, a comment is provided on the gaps and possible directions that future research could follow to allow the extensive use of wireless sensor networks for pavement health condition monitoring.

The Asian Forum for Polar Sciences: An assessment of regional cooperation

引用

Advances in Polar Science 2019年第1期30卷 1-10页

作者： Andrea colombo Gateway Antarctica University of Canterbury

This paper presents a review of the current status of Asian countries' relations with Antarctica, aimed at deepening understanding of the role of the Asian Forum for Polar Sciences(AFoPS) in the area covered under the Antarctic Treaty. The paper critically examines the current situation regarding the Asian presence in Antarctica and provides a historical outline of the AFo PS. Whereas the activities of individual Asian countries in Antarctica have been extensively analyzed in previous studies, those of the AFoPS constitute a research gap within the scholarly literature. Therefore, an assessment of the role of the AFoPS within the wider Antarctic region from both the policy and scientific perspectives is necessary to better understand its relationship with other international organizations that are active in the area covered by the Antarctic Treaty. Over the course of its relatively short history, the AFoPS has accomplished a number of achievements. These include the signing of a Memorandum of Understanding with the International Arctic Science Committee and the Scientific Committee on Antarctic Research. Additionally, collaborative activities have been undertaken by members of the Forum, entailing, for example, exchanges of personnel, cooperation and support extended within scientific projects. Consequently, AFo PS member countries that traditionally lack a polar background, such as Thailand and Vietnam, have been able to conduct scientific activities in Antarctica.

We review recent developments on the synthesis and properties of two-dimensional materials which, although being mainly of an sp^(2) bonding character, exhibit highly disordered, non-uniform and structurally random morphologies. The emergence of such class of amorphous materials, including amorphous graphene and boron nitride, have shown superior properties compared to their crystalline counterparts when used as interfacial films. In this paper we discuss their structural,vibrational and electronic properties and present a perspective of their use for electronic applications.

Hybrid Short-term Load Forecasting Method Based on Empirical Wavelet Transform and Bidirectional Long Short-term Memory Neural Networks

引用

Journal of Modern Power Systems and Clean Energy 2022年第5期10卷 1216-1228页

作者： Xiaoyu Zhang Stefanie Kuenzel Nicolo colombo Chris Watkins School of Artificial Intelligence Anhui UniversityHefei 230601China Department of Electronic Engineering Royal HollowayUniversity of LondonEgham HillEgham TW20 OEXUK Department of Computer Science Royal HollowayUniversity of LondonEgham HillEgham TW200EXUK

Accurate short-term load forecasting is essential to modern power systems and smart grids. The utility can better implement demand-side management and operate power system stably with a reliable load forecasting system. The load demand contains a variety of different load components, and different loads operate with different frequencies. The conventional load forecasting methods, e.g., linear regression(LR), auto-regressive integrated moving average(ARIMA), deep neural network, ignore the frequency domain and can only use time-domain load demand as inputs. To make full use of both time-domain and frequency-domain features of the load demand, a load forecasting method based on hybrid empirical wavelet transform(EWT) and deep neural network is proposed in this paper. The proposed method first filters noises via wavelet-based denoising technique, and then decomposes the original load demand into several sub-layers to show the frequency features while the time-domain information is preserved as well. Then, a bidirectional long short-term memory(LSTM) method is trained for each sub-layer independently. In order to better tune the hyperparameters, a Bayesian hyperparameter optimization(BHO) algorithm is adopted in this paper. Three case studies are designed to evaluate the performance of the proposed *** the results, it is found that the proposed method improves the prediction accuracy compared with other load forecasting method.

RIGOROUS ESTIMATES ON BALANCE LAWS IN BOUNDED DOMAINS

引用

Acta Mathematica Scientia 2015年第4期35卷 906-944页

作者： Rinaldo M.colombo Elena ROSSI Unità INdA M Università di Brescia Dipartimento di Matematica ed Applicazioni Università di Milano-Bicocca

The initial-boundary value problem for a general balance law in a bounded domain is proved to be well posed. Indeed, we show the existence of an entropy solution, its uniqueness and its Lipschitz continuity as a function of time, of the initial datum and of the boundary datum. The proof follows the general lines in [4], striving to provide a rigorous treatment and detailed references.
