Significant efforts have been made to regulate the electron structure and optimize the electron distribution, thereby increasing the catalytic activity. However, this focus often overshadows an equally essential aspect of HAOPs: the adsorption effect. Adsorption is a critical initiator for triggering the interaction of oxidants and contaminants with heterogeneous catalysts. The efficacy of these interactions is influenced by a variety of physicochemical properties, including surface chemistry and pore sizes, which determine the affinities between contaminants and material surfaces. This disparity in affinity is pivotal because it underpins the selective removal of contaminants, especially in complex waste streams containing diverse contaminants and competing matrices. Consequently, understanding and mastering these interfacial interactions is fundamentally indispensable not only for improving process efficiency but also for enhancing the selectivity of contaminant removal. Herein, we highlight the importance of adsorption-driven interfacial interactions for fundamentally elucidating the catalytic mechanisms of HAOPs. Such interactions dictate the overall performance of the treatment processes by balancing the adsorption, reaction, and desorption rates on the catalyst surfaces. Elucidating the adsorption effect not only shifts the paradigm in understanding HAOPs but also improves their practicality in water treatment and wastewater decontamination. Overall, we propose that revisiting adsorption-driven interfacial interactions holds great promise for optimizing catalytic processes to develop effective HAOP strategies.</div></div>","PeriodicalId":11783,"journal":{"name":"Engineering","volume":"47 ","pages":"Pages 22-25"},"PeriodicalIF":10.1,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143863389","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Continuous improvements in the accuracy of surface mass loading products, performance of Earth models, and precise data-processing technologies have significantly advanced research on the effects of environmental loading on nonlinear variations in GNSS coordinate time series. However, owing to theoretical limitations, the lack of high spatiotemporal resolution surface mass observations, and the coupling of GNSS technology-related systematic errors, environmental loading and nonlinear GNSS reference station displacements remain inconsistent. The applicability and capability of these loading products across different regions also require further evaluation. This paper outlines methods for modeling environmental loading, surface mass loading products, and service organizations. In addition, it summarizes recent advances in applying environmental loading to address nonlinear variations in global and regional GNSS coordinate time series.

However, current robots lack the capacity for human-like action and evolution, posing a bottleneck to improving robotic intelligence. Existing research predominantly models robots as one-way, static mappings from observations to actions, neglecting the dynamic processes of perception and behavior. This paper introduces a novel approach to robot cognitive learning by considering physical properties. We propose a theoretical framework wherein a robot is conceptualized as a three-body physical system comprising a perception-body (P-body), a cognition-body (C-body), and a behavior-body (B-body). Each body engages in physical dynamics and operates within a closed-loop interaction. Significantly, three crucial interactions connect these bodies. The C-body relies on the P-body’s extracted states and reciprocally offers long-term rewards, optimizing the P-body’s perception policy. In addition, the C-body directs the B-body’s actions through sub-goals, and subsequent P-body-derived states facilitate the C-body’s cognition dynamics learning. At last, the B-body would follow the sub-goal generated by the C-body and perform actions conditioned on the perceptive state from the P-body, which leads to the next interactive step. These interactions foster the joint evolution of each body, culminating in optimal design. To validate our approach, we employ a navigation task using a four-legged robot, D’Kitty, equipped with a movable global camera. Navigational prowess demands intricate coordination of sensing, planning, and D’Kitty’s motion. Leveraging our framework yields superior task performance compared with conventional methodologies. In conclusion, this paper establishes a paradigm shift in robot cognitive learning by integrating physical interactions across the P-body, C-body, and B-body, while considering physical properties. Our framework’s successful application to a navigation task underscores its efficacy in enhancing robotic intelligence.</div></div>","PeriodicalId":11783,"journal":{"name":"Engineering","volume":"47 ","pages":"Pages 168-179"},"PeriodicalIF":10.1,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143864143","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Logistics engineering management plays a crucial role in ensuring the efficient operation of PSCs and contributes to the construction of a global economic system. Given its importance to the efficiency of PSCs, the choice of logistics service strategy in logistics engineering management has attracted considerable scholarly attention. However, the current research is fragmented and lacks systematic analysis and synthesis. This paper provides a comprehensive overview of logistics engineering management in PSCs from the perspective of logistics service strategy selection from January 2005 to September 2024. To this end, we first review the research related to self-built logistics (SBL) and third-party logistics (3PL) in PSCs due to the complete independence of these two logistics service strategies. The results show that the following two topics are of great interest to researchers. One is the choice of the optimal logistics service strategy for the members of PSCs, while the other is the impact of factors related to logistics services on PSCs, including the channel selection, platform entry, sales model, and so forth. Next, we summarize the determinants influencing the choice between SBL and 3PL for the members of PSCs. The results indicate that the influencing factors are the service cost and service level, followed by the channel, brand, market potential, and competition. Then, on the basis of the themes of logistics service sharing (LSS), we review the research on LSS in PSCs, as LSS often emerges as an innovative model after a certain stage of development in SBL and 3PL. We find that LSS is regarded as an important complement to SBL and 3PL, with key research hotspots, including the channel, partner selection, and service competition. Service cost is a major factor influencing LSS, with competition, consumers’ logistics preference, and market potential being secondary factors. Finally, this paper outlines several important and promising directions for future research. This paper has important management implications for building a modern logistics system and promoting the transformation of PSCs.</div></div>","PeriodicalId":11783,"journal":{"name":"Engineering","volume":"47 ","pages":"Pages 236-249"},"PeriodicalIF":10.1,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143864154","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
