Abstract An imbalance in reactive oxygen species (ROS) levels tumor cells can result the accumulation of lipid peroxide (LPO) which induce ferroptosis. Moreover, elevated ROS tumors present a chance to develop ROS‐based cancer therapeutics including photodynamic therapy (PDT) and However, their anticancer efficacies are compromised by insufficient inherent cellular regulatory mechanism. Herein, cell membrane‐targeting photosensitizer, TBzT‐CNQi, generate 1 O 2 , •OH, •− via type I/II process...

Photo-immunotherapy faces challenges from poor immunogenicity and low response rate due to hypoxic microenvironment. This study presents Rh-PTZ, a small organic molecule with D-π-A structure, that simultaneously amplifies mitochondria-targeted type-I PDT-dependent immune stimulation for the treatment of cancer. The hydrophobic Rh-PTZ was encapsulated into F127 prepare nanoparticles (Rh-PTZ NPs). ROS generation ability, mitochondrial targeting capacity, ICD triggering effect mediated by NPs...

Subgraph counting, as a fundamental problem in network analysis, is to count the number of subgraphs data graph that match given query by either homomorphism or subgraph isomorphism. The importance counting derives from fact it provides insights large graph, particular labeled when collection graphs with different sizes and labels are issued. challenging. On one hand, exact enumerating NP-hard. % other approximate isomorphism can only support 3/5-node over unlabeled graphs. Another way for...

Given a network with social and spatial information, cohesive group queries aim at finding of users, which are strongly connected closely co-located. Most existing studies limit to groups either the strongest ties under certain constraint or minimum distance constraints. It is difficult for users decide constraints they need choose how priority meet their real requirements since different in nature. In this paper, we take new approach consider equally study skyline query. Specifically, given...

Simultaneous Localization and Mapping (SLAM) has become a critical technology for intelligent transportation systems autonomous robots is widely used in driving. However, traditional manual feature-based methods challenging lighting environments make it difficult to ensure robustness accuracy. Some deep learning-based show potential but still have significant drawbacks. To address this problem, we propose novel hybrid system visual SLAM based on the LightGlue learning network. It uses local...

Abstract To solve the accurate positioning problem of mobile robots, simultaneous localization and mapping (SLAM) or visual odometry (VO) based on information are widely used. However, most SLAM VO cannot meet accuracy requirements in dynamic indoor environments. This paper proposes a robust deep learning to eliminate feature points matching error. when camera objects relative motion, frames will produce ghosting, especially high-dynamic environments, which bring additional error; view this...

With the advent of XML as a standard for data representation and exchange on Internet, storing querying becomes more important. This poses new challenge concerning indexing searching data, because conventional approaches based relational model may not meet processing requirements data. In this paper, we propose path index Patricia-tries, namely PT index. Our structure offers several novel features. First, it can support to fast search by its Patricia-tries. Second, indexes are compressed so...
