We propose a wavelength-saving topology of quantum key distribution (QKD) network based on passive optical elements, and we report the field test this commercial telecom fiber at frequency 20MHz. In network, five nodes are supported with two wavelengths, every can share secure keys directly same time. also characterized insertion loss cross talk effects point-to-point QKD system after introducing network.
Abstract β-Glucosidases are enzymes that hydrolyze β-glycosidic bonds to release non-reducing terminal glucosyl residues from glycosides and oligosaccharides thus have significant application potential in industries. However, most β-glucosidases feedback inhibited by the glucose product, which restricts their application. Remarkably, some of glycoside hydrolase (GH) 1 family tolerant or even stimulated glucose. Elucidation mechanisms tolerance stimulation GH1 will be crucial improve through...
Abstract Ecological restoration of mine tailings have impact on soil physiochemical properties and microbial communities. The surface has been a primary concern in the past decades, however it remains poorly understood about adaptive response communities along profile during ecological tailings. In this study, 60-cm were investigated tailing pond bare waste (BW) with two vegetated soils Imperata cylindrica (IC) Chrysopogon zizanioides (CZ) plants. Revegetation both IC CZ could retard...
With the popularity of social networks and increase cloud platform applications, service computing has also developed. Therefore, protection information even privacy uploaded to server become critical. Recently, some researchers have proposed encryption schemes visual meaningful image by using compressive sensing. However, these generally cannot hide large-size plain into small-size cover recover original lossless. To solve above problems, this paper a visually scheme based on lossless...
Protection of medical data has become a prerequisite in imaging clouds due to the semi-trusted cloud. Aiming at preserving patients' privacy and increasing security images cloud, this letter proposes secure privacy-preserving technique which provides new mechanism for data. In technique, novel reversible hiding (RDH) based on adaptive texture classification is proposed embed into improving image quality, plaintext encryption encrypt marked similar target security. Extensive experiments have...
Visual odometry (VO) plays a crucial role in autonomous driving, robotic navigation, and other related tasks by estimating the position orientation of camera based on visual input. Significant progress has been made data-driven VO methods, particularly those leveraging deep learning techniques to extract image features estimate poses. However, these methods often struggle low-light conditions because reduced visibility increased difficulty matching keypoints. To address this limitation, we...
Reversible data hiding methods for color images are investigated because of the popularity images. However, traditional RDH only take PSNR as assessment metric and pursue a high value. To further consider different subjective perception in R, G, B channels image, this paper proposes visual quality image reversible scheme based on B-R-G embedding principle CIEDE2000 metric. In method, double-layer least square prediction is proposed to satisfy sorting requirement maintain accuracy, then...
Summary Conservation plans for waterbirds in periodically flooded wetlands should be based on a deep understanding of the relationship between habitat availability and hydrological regime. Using waterbird surveys remotely sensed images, we investigated how wintering was regulated by seasonal water level fluctuation at Shengjin Lake lower Yangtze River floodplain, which is an important area along East Asian-Australasian Flyway. We recorded 52 species during three field surveys, categorised...
Recursive code construction (RCC), based on the optimal transition probability matrix (OTPM), approaching rate-distortion bound of reversible data hiding (RDH) has been proposed. Using existing methods, OTPM can be effectively estimated only for a consistent distortion metric, i.e., if host elements at different positions share same metric. However, in many applications, metrics are position dependent and should thus inconsistent. Inconsistent usually quantified as multi-distortion In this...
Medical data security is facing great challenges in medical applications due to the open internet and semi-trusted cloud. For sake of privacy protection images, this paper proposes a secure high visual-quality framework for images. In framework, novel reversible hiding (RDH) based on lesion extraction embeds into images image quality improvement, homomorphic encryption chaotic map encrypts security. The experiments have shown that proposed increases improves visual significantly. RDH...
The aim of this study was to use an econometric analysis investigate the relationship between agricultural gross domestic product (AGDP) and variables such as apple, citrus, pears, grape banana in Pakistan; data were explored from 1980 2015; we used time series collected secondary sources, including Pakistan Bureau Statistics, Statistical Year Books Economic Survey Pakistan. Data analyzed by using Ordinary Least Square (OLS) method Augmented Dickey Fuller (ADF) test, results interpreted...
Image and video labeling is important for computers to understand images videos image search. Manual tedious costly. Automatically yet a dream. In this paper, we adopt Web 2.0 approach efficiently: Internet users around the world are mobilized apply their "common sense" solve problems that hard today's computers, such as videos. We first propose general human computation framework binds problem providers, sites, together large-scale common sense efficiently economically. The addresses...
Image processing is a very popular and widely used technique. In this paper, we propose framework for realizing reversible image processing, which enables that the users can return processed to original copy without loss. proposed method, firstly get desired target by classic method. Then reversibly according transition probability matrix, getting similar image. We take histogram equalization gamma transform as examples show method realize achieve nearly same effect done irreversible tools.
