Storage deduplication improves write latency, increases available space, and reduces thewear of storage media by eliminating redundant writes. the flash translation layer (FTL) of a flash solid state disk (SSD) easily enables deduplication in an SSD through the simple mapping of duplicated logical pages to the same physical page. therefore, a few deduplicating FTLs have been proposed. However, the deduplication of partially duplicated files breaks the sequentiality of data storage at the flash page level, resulting in a significant degradation of the read performance. Although increasing available storage space, reducing flash write, and extending lifespan are barely perceptible to users, extended read latency is critical to user-perceived performance. In this paper, we propose a novel deduplication FTL called Dedup-for-Speed (DFS). the DFS FTL trades surplus capacity gained through inline deduplication for improved read performance by storing duplicated pages in fast flash modes, such as the pseudo-single-level-cell(pSLC) mode. the flash mode of a page is determined by its degree of deduplications. Duplicate pages are migrated to fast flash blocks during idle intervals to minimize interference with host-issued operations. Contrary to conventional deduplication schemes, DFS improves the read performance while maintaining the aforementioned benefits of deduplication. Our evaluation of six real-world traces showed that DFS improved the read latency by 16 % on average and up to 34 %. It also enhanced the write latency by 64 % on average and up to 82 %.

the monograph "Strong Artificial Intelligence. On the Approaches to Superintelligence", referenced by this paper, provides a cross-disciplinary review of Artificial General Intelligence (AGI). As an anthropomorphic direction of research, it considers Brain Principles programming (BPP) - the formalization of universal mechanisms (principles) of the brain's work with information, which are implemented at all levels of the organization of nervous tissue. this monograph provides a formalization of these principles in terms of the category theory. However, this formalization is not enough to develop algorithms for working withthis information. In the paper, for the description and modeling of BPP, it is proposed to apply mathematical models and algorithms developed by us earlier that model cognitive functions, which are based on well-known physiological, psychological and other natural science theories. the paper uses mathematical models and algorithms of the following theories: ***'s theory of functional Brain Systems, Eleonor Rosh's prototypical categorization theory, Bob Rehter's theory of causal models and "natural" classification. As a result, the formalization of the BPP is obtained and computer examples are given that demonstrate the algorithm's operation.

We implement extraction of Coq programs to functional languages based on MetaCoq's certified erasure. As part of this, we implement an optimisation pass removing unused arguments. We prove the pass correct wrt. a conventional call-by-value operational semantics of functional languages. We apply this to two functional smart contract languages, Liquidity and Midlang, and to the functional language Elm. Our development is done in the context of the ConCert framework that enables smart contract verification. We contribute a verified boardroom voting smart contract featuring maximum voter privacy such that each vote is kept private except under collusion of all other parties. We also integrate property-based testing into ConCert using QuickChick and our development is the first to support testing properties of interacting smart contracts. We test several complex contracts such as a DAO-like contract, an escrow contract, an implementation of a Decentralized Finance (DeFi) contract which includes a custom token standard (Tezos FA2), and more. In total, this gives us a way to write dependent programs in Coq, test them semi-automatically, verify, and then extract to functional smart contract languages, while retaining a small trusted computing base of only MetaCoq and the pretty-printers into these languages.

the emerging Digital Engineering demands digital representation of the system of interest and sharing models and data across the boundaries of organizations and the boundaries of the engineering lifecycle. Towards this direction, it is critical to develop systems modeling languages and tools that accommodate Digital Engineering. this paper presents our research on semantic mapping from System Modeling Language (SysML) to functional Reactive programming (FRP) withthe goal of developing computing mechanisms withfunctional reactive programming to support executable and verifiable SysML model specification.
