This study describes the fundamentals of assessing the vulnerability of coral islands, as well as environmental management and resource exploitation. Using seabird subfossils, such as bones, guano, eggshells etc., which have been well preserved on the Xisha Islands in the South China Sea, the author identifies the influences of climate change and human activity on seabird populations and diets. Understanding the past is of great importance for predicting the future, and seabird subfossils provide valuable information, which can be used to study changes in seabird ecology, paleoceanography...

This book presents a comprehensive review of recent developments in vanadium-based nanomaterials for next-generation electrochemical energy storage. The basic electrochemical energy storage and conversion equipment are elaborated, and the vanadium-based nanomaterials of the synthesis approaches, characterizations, electrochemical storage mechanisms, and performance optimization tactics are discussed. Examples are taken from various chemical energy storage devices to expound the functions of advanced vanadium-based nanomaterials for specific applications. Finally, various challenges and...

This book presents an in-depth exploration of multimodal learning toward recommendation, along with a comprehensive survey of the most important research topics and state-of-the-art methods in this area.

First, it presents a semantic-guided feature distillation method which employs a teacher-student framework to robustly extract effective recommendation-oriented features from generic multimodal features. Next, it introduces a novel multimodal attentive metric learning method to model user diverse preferences for various items. Then it proposes a disentangled multimodal representation...
