Logistic regression is a powerful machine learning tool to classify data. When dealing with sensitive data such as private or medical information, cares are necessary. In this paper, we propose secure system for protecting the training in logistic via homomorphic encryption. Perhaps surprisingly, despite non-polynomial tasks of regression, show that only additively encryption needed build our system. Our and scalable dataset size.

Moreover, radical form MV+• can also be effectively included C5AS.

A water-soluble fluorescent zinc sensor which binds strongly to Zn2+ (log K = 12.4) was successfully synthesized under physiological conditions. This exhibits a good fluorescence response over wide pH range in water. Under the same conditions, several metal ions commonly present environment, such as Na+, K+, Ca2+, Mg2+, Mn2+, Fe2+, and Co2+, showed little interference Zn2+.

Logistic regression is a powerful machine learning tool to classify data. When dealing with sensitive or private data, cares are necessary. In this paper, we propose secure system for privacy-protecting both the training and predicting data in logistic via homomorphic encryption. Perhaps surprisingly, despite non-polynomial tasks of regression, show that only additively encryption needed build our system. Indeed, instantiate Paillier, LWE-based, ring-LWE-based schemes, highlighting merits...

Possessing four cationic pyridium groups, phenyl-bridged bis(triphenylamine) derivatives (G1, G2) were encapsulated by cucurbit[8]uril (CB[8]) at a 1:2 stoichiometry to form the network-like organic two-dimensional nanosheet, which could efficiently enhance near-infrared (NIR) luminescence and companies with red-shift from 750 810 nm for G1. Benefiting supramolecular multivalent interaction, α-cyclodextrin modified hyaluronic acid (HACD) G1/CB[8] formed nanoparticles further NIR behaviors....

In SAC'05, Strangio proposed protocol ECKE- 1 as an efficient elliptic curve Diffie-Hellman two-party key agreement using public authentication. this letter, we show that ECKE-1 is vulnerable to key-compromise impersonation attacks. We also present improved - ECKE-1N, which can withstand such The new protocol's performance comparable the well-known MQV and maintains same remarkable list of security properties.

A linear supramolecular ternary polymer based on two host-guest interactions in an orthogonal way was constructed, by taking advantage of the distinguishable binding properties between cyclodextrin and calixarene.

Web page keyword extraction is widely used in web text classification, clustering, and information retrieval. However, the of Chinese still need be improved applied, especially medical field. This paper proposes an TF-IDF algorithm based on WF-TF-IDF to extract keywords from page. The considers three factors which are word frequency title, description distribution categories corpus. We do data-preprocessing includes denoising, regular expression processing, segmentation, synonyms exchanging...

In a photovoltaic DC microgrid, the intermittent power supply of distributed generation and fluctuation load will cause instability bus voltage. An improved super-twisting sliding mode control method based on algorithm is proposed to solve this problem. paper, bidirectional half-bridge buck–boost converter was selected as research topic. The replaces sign function with saturation further mitigate chattering effect. stability proven be finite-time convergent using Lyapunov theory control....

Abstract In recent years, federated learning has received much attention because it involves the collaboration of each client to train a strong model without infringing data privacy. Machinery fault diagnosis also benefits from this technology. However, different operating conditions and diagnostic tasks for lead heterogeneity among devices, which brings tough challenge machinery diagnosis. To solve problem, we explore method based on similarity (FedSC). Considering client, FedSC customizes...

As one of the promising information-centric networking (ICN) architectures, NDN has attracted tremendous research attention and effort in past decade. In particular, security privacy remain significant concerns challenges due to fact that most traditional cryptographic primitives are no longer suitable for architecture. For example, aim secure point-to-point communications, always requiring explicit descriptions where or whom data packets intended, while network addressing locating becomes...

The sex of an animal influences its economic traits, especially in species displaying sexual dimorphism. Chinese soft-shelled turtle, Pelodiscus sinensis, is economically important aquatic that shows significant male dimorphism, with a large body size, faster growth, thick and wide calipash, lower fat. In this study, ten female turtles were subjected to restriction site-associated DNA sequencing (RAD-seq) using the Hi-Seq 4000 platform isolate female-specific fragments. We identified 5967 bp...
