In distributed storage systems, regenerating codes can achieve the optimal tradeoff between capacity and repair bandwidth. However, a critical drawback of existing codes, in general, is high coding complexity, since processes involve expensive multiplication operations finite field. this paper, we present design framework which employ binary addition bitwise cyclic shift as elemental operations, named BASIC codes. The proposed be regarded concatenated code with outer being parity-check code,...
The past few decades have witnessed explosive development in drug delivery systems. However, vivo suffers from non-specific distribution non-targeted organs or tissues, which may cause undesired side effects and even genotoxicity. Here, a general strategy that enables tuning the tropism of polymersomes for liver- spleen-selective is reported. By using library screening approach, spleen-targeted polymersome PH9-Aln-8020 liver-targeted PA9-ZP3-5050 are identified accordingly. Meanwhile, second...
Array codes are used widely in data storage systems such as redundant array of independent disks. The row-diagonal parity (RDP) and EVENODD two popular double-parity codes. increasing capacity hard disks demands better fault tolerance by using with three or more Although many extensions RDP have been proposed, their main drawback is high decoding complexity. In this paper, we propose a unified form under which can be treated shortened Moreover, an efficient algorithm based on LU...
The blockchain has a great vogue in recent years, and its core consensus algorithms also become the focus of research. At present, most research on mechanisms are oriented to public based existing or sophisticated distributed algorithms. Various application scenarios have been developed consortium blockchain, while few researchers pay attention customize consistency Moreover, there is trade-off between security performance designing mechanisms. We propose novel algorithm called Proof Vote...
The metaverse gradually evolves into a virtual world containing series of interconnected sub-metaverses. Diverse digital resources, including identities, contents, services, and supporting data, are key components the sub-metaverse. Therefore, Domain Name System (DNS)-like system is necessary for efficient management resolution. However, legacy DNS was designed with security vulnerabilities trust risks due to centralized issues. Blockchain used mitigate these concerns its decentralized...
Objectives: Amyotrophic lateral sclerosis (ALS) is a progressive and fatal disease characterized by the degeneration of spinal cord brain neurons. Proteomics combined with Mendelian randomization (MR) an effective method for finding treatment targets. Methods: We aimed to seek new therapeutic targets ALS. A large-scale GWAS on proteomics (4907 circulatory protein) 35,559 individuals was included as exposure data; 138,086 ALS patients used outcome we found that high level sex hormone-binding...

As a subset of distributed systems, blockchain technology is equally bound by the CAP trilemma. Specifically, no system can satisfy consistency, availability, and partition tolerance simultaneously. Informally, innovative trilemma has been theorized to include security, scalability, decentralization. While many software approaches on blockchains claim solve problem, almost all known have proven involve tradeoffs fail reach upper bounds, meaning they do not achieve theoretical limit value in...
