Nelumbo nucifera Gaertn., Eleocharis dulcis , Sagittaria sagittifolia L., and Trapa bispinosa Roxb. are common aquatic vegetables that are rich in starch. Starches from these four aquatic vegetables and their applications in edible films were studied to facilitate full use of starch resources. Significant differences in transparency, freeze–thaw stability, water solubility index, swelling power, water and oil absorption capacities, starch particle morphology, and rheology were observed among the starches from these four aquatic vegetables. All starches exhibited a typical "A" type diffraction pattern. N. nucifera , E. dulcis , and S. sagittifolia starches have similar thermal properties, while T. bispinosa starch has a higher gelatinization temperature. S. sagittifolia starch film has the highest transparency and lower WVP and water solubility. These results will promote the development of products based on starch obtained from aquatic vegetables.

Popularization of wireless power transfer (WPT) has promoted the multi-disciplinary explorations and integration. It gradually incubates numerous attractive solutions for industrial, domestic and medical scenarios. Therefore, a series of smart WPT emerges, and these state-of-the-arts will bring a great impact on the modern technology and human society. This review investigates and discusses the opportunities and challenges of the smart WPT, especially in the areas of wireless energy modulation, conversion and intellectualization. The key is to reveal the methodologies, approaches and foresights for the emerging technologies of the smart WPT. As one of the most promising development trends, the smart WPT will embrace the information-energy internet and construct the wireless energy router and wireless energy internet that support the wireless energy trading for peers, communities and energy internets. [Display omitted] • Methodologies, approaches and features of smart WPT are discussed. • Wireless energy modulation, conversion and intellectualization are presented. • Foresights and development trends of future smart WPT are envisioned. • Wireless energy router and internet will support energy trading as well as data and energy sharing in smart cities.

Micro-expression is a kind of spontaneous facial expression, which is with short duration and low intensity. Because of its involuntary feature, it is helpful to reveal one's true emotion when someone tries to conceal. Therefore, it has attracted a great of attentions from the field of affective computing. Previous methods focus on recognizing micro-expression on the whole face. In fact, it is worthy to note that micro-expression often appears in the eye area. In this paper, we present a framework to recognize micro-expressions within the eye region, namely eyeME. Specifically, the LBP-TOP feature is extracted from the eye region, and multiple classifiers are trained to recognize the expressions. We test the proposed framework on the widely used CASME2 database. The experimental results showed that the proposed eyeME framework performs better than the methods using the whole face and mouth region when identifying happy and disgust expressions. It confirmed that the information on eye region is critical to the recognition of these kinds of micro-expressions. [ABSTRACT FROM AUTHOR]

• 52 Gα subunit genes were identified in eight Rosaceae species, and phylogenetic, conserved motif, and structural characteristics implied their functional similarity and specificity. • Purifying selection has played a key role in the evolution of Gα subunit genes. • Expression analysis reveals diverse expression patterns and might play a key role in response to heat stress. • Gα subunit genes were shown to be located in the plasma membrane and nucleus in pear. The Gα subunit is an important component of the heterotrimeric G-protein complex and an integral component of several signal transduction pathways. It plays crucial roles in the diverse processes of plant growth and development, including the response to abiotic stress, regulation of root development, involvement in stomatal movement, and participation in hormone responses, which have been well investigated in many species. However, no comprehensive analysis has identified and explored the evolution, expression pattern characteristics and heat stress response of the Gα subunit genes in Rosaceae. In this study, 52 Gα subunit genes were identified in eight Rosaceae species; these genes were divided into three subfamilies (I, II, and III) based on their phylogenetic, conserved motif, and structural characteristics. Whole genome and dispersed duplication events were found to have contributed significantly to the expansion of the Gα subunit gene family, and purifying selection to have played a key role in the evolution of Gα subunit genes. An expression analysis identified some PbrGPA genes that were highly expressed in leaf, root, and fruit, and exhibited diverse spatiotemporal expression models in pear. Under abiotic stress conditions, the mRNA transcript levels of PbrGPA genes were up-regulated in response to high temperature treatment in leaves. Furthermore, three Gα subunit genes were shown to be located in the plasma membrane and nucleus in pear. In conclusion, the study of the Gα subunit gene family will help us to better understand its evolutionary history and expression patterns, while facilitating further investigations into the function of the Gα subunit gene in response to heat stress.
