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.

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.
