Security is a key problem for the transmission, interchange, and storage process of multimedia systems applications. In 2018, Li et al. proposed in-depth security analysis on an image encryption algorithm based first-order time-delay system (IEATD) gave specific chosen-plaintext attack it. Moreover, enhanced version called as IEACD was designed to fix reported defects. This article analyzes essential structures two algorithms evaluates their real performances: 1) no efficient nonlinear...

Recent developments in Unmanned Aircraft Vehicles (UAVs), thermal imaging, and Auto-machine learning (AutoML) have shown high potential for precise wildlife surveys but rarely been studied habitat assessment. Here, we propose a framework that leverages these advanced techniques to achieve cost-effective quality assessment from the perspective of actual community usage. The exploits vision intelligence hidden UAV images AutoML methods distribution mapping, then derives use indicators imply...

Nonrelativistic energies for the low-lying states of lithium are calculated using variational method in Hylleraas coordinates. Variational eigenvalues infinite nuclear mass case with up to 34 020 terms $\ensuremath{-}7.478\phantom{\rule{0.16em}{0ex}}060\phantom{\rule{0.16em}{0ex}}323\phantom{\rule{0.16em}{0ex}}910\phantom{\rule{0.16em}{0ex}}147(1)$ a.u. $1{s}^{2}2s{\phantom{\rule{0.16em}{0ex}}}^{2}\phantom{\rule{-0.16em}{0ex}}S$,...

The rising machine learning (ML) models have become the preferred way for landslide detection based on remote sensing images, but performance of these in a sample-free area are rarely concerned many studies. In this study, we used cross-validation method (training model one and validation another) to compare portability trained ML applied an “off-site” area, as consideration ability areas. We integrate nighttime light imagery, multi-seasonal optical Landsat time-series digital elevation...

Physical-layer key agreement is used to generate a shared between devices on demand. Such schemes utilize the characteristics of wireless channel from device-to-device channel. As all are time-dependent and location-dependent, it hard for eavesdroppers get key. However, most research works in this area use passive attack models whereas active attacks that aim at manipulating also possible. with User Introduced Randomness (PHYUIR) solution similar Diffie-Hellman protocol against such kind...

We present improved calculations of variational energy eigenvalues for the $1{s}^{2}2s {}^{2}S$, $1{s}^{2}3s and $1{s}^{2}2p {}^{2}P$ states lithium using basis sets with up to 30 224 terms in Hylleraas coordinates. The nonrelativistic energies infinite nuclear mass are $\ensuremath{-}7.478 060 323 910 143 7(45)$ a.u. $\ensuremath{-}7.354 098 421 444 316 4(32)$ $\ensuremath{-}7.410 156 532 651 6(5)$ {}^{2}P$, which represent most accurate upper bounds date. An important advantage multiple...

When authenticating a group of radio-frequency identification tags, common method is to authenticate each tag with some challenge-response exchanges. However, sequentially individual tags one by might not be desirable, especially when considering that reader often has deal multiple within limited period, since it will incur long scanning time and heavy communication costs. To address these problems, we put forward novel efficient authentication protocol, where can authenticated...

The proposed approach helps monitor at landscape scale efficient low-cost manner. results...

Woody plant encroachment into grasslands ecosystems causes significantly ecological destruction and economic losses. Effective efficient management largely benefits from accurate timely detection of encroaching species at an early development stage. Recent advances in unmanned aircraft systems (UAS) enabled easier access to ultra-high spatial resolution images a centimeter level, together with the latest machine learning based image segmentation algorithms, making it possible detect...

Physical layer key agreement is a new kind of schemes used to generate shared between pervasive and resource constrained devices. These utilize the characteristics wireless channel key. As all are time-depend location-depend, it hard for eavesdroppers get But lacks research on active attacks which aim at manipulating PHY-UIR (PHYsical with User Introduced Randomness) only paper proposes solution in detail against such attacks. In this paper, we propose attack can not prevent. We call session...

Liquid scintillators are commonly used to detect low energy neutrinos from the reactors, sun, and earth. It is a challenge reconstruct deposited energies for large liquid scintillator detector. For detectors with multiple optical mediums such as JUNO SNO+, prediction of propagation detected photons extremely difficult due mixed processes Rayleigh scattering, refraction total reflection at their boundaries. Calibration based reconstruction methods consume impractical time since number...

The epidemiological features of the Klebsiella pneumoniae causing bloodstream infections in Hong Kong and their potential threats to human health remained unknown. K. strains collected from four hospitals during period 2009-2018 were subjected molecular typing, string test, antimicrobial susceptibility testing, whole genome sequencing analysis. Clinical data patients whom these isolated analyzed retrospectively using univariate multivariate logistic regression approaches. 240 spp. belonged...

This paper explores the design of an architecture that replaces Disk with Persistent Memory (PM) to achieve highest I/O throughput in Log-Structured Merge Tree (LSM-Tree) based key-value stores (KVS). Most existing LSM-Tree KVSs use PM as intermediate or smoothing layer, which fails fully exploit PM's unique advantages maximize throughput. However, due distinct characteristics, such byte addressability and short erasure time, simply replacing storage does not yield optimal performance....
