    Just noticeable distortion model based on entropy masking in DCT domain by Qionghua LUO, Hongkui WANG, Haibing YIN, Yafen XING

    Published 2023-02-01
    “…In order to improve the threshold accuracy of JND (just noticeable distortion) model in DCT (discrete cosine transform) domain and avoid cross-domain operation, entropy masking effect was introduced into DCT-based JND model.Firstly, starting from the free-energy theory and the Bayesian inference, an autoregressive model based on texture-energy similarity in DCT domain was designed to simulate the spontaneous prediction behavior of visual perception.Secondly, the mapping relationship between visual perception and prediction residuals were explored to obtain the disorder intensity in block level.Thirdly, the entropy masking effect was modeled as a JND threshold modulation factor of disorder intensity.Finally, the JND model in DCT domain for the entropy masking was proposed by fusing the contrast sensitivity function, the luminance adaptive masking, the contrast masking.Compared with the existing JND model in DCT domain, the proposed model performed all operations in DCT domain, which was more efficient and concise.The subjective and objective experimental results indicate that the proposed JND model shows greater tolerance to distortion with better perceptual quality.…”

    Effect of Al addition on phase constituent and corrosion behaviors of AlxCrFeMo0.5Ni2 high-entropy alloys by Yu-qi Ma, Wei Zhang, Qing-chun Xiang, Ying-lei Ren, Ke-qiang Qiu

    Published 2025-03-01
    “…When x increases to 2.0, the alloy is completely composed of two kinds of body-centered cubic (BCC) phases, in which the dendritic phase is not changed while the interdendritic phase transforms from the σ phase into a disordered BCC structure. The Al2.0CrFeMo0.5Ni2 HEA exhibits the best anti-corrosion capacity in the NaCl solution, with the lightest degree of galvanic corrosion due to the electric potential difference between the BCC phase and the ordered B2 phase is small and the minimum corrosion current density of 132 nA/cm2 among the studied alloys.…”

    The Role of Non-Genomic Information in Maintaining Thermodynamic Stability in Living Systems by Robert A. Gatenby, B. Roy Frieden

    Published 2004-10-01
    “…Living systems represent a local exception, albeittransient, to the second law of thermodynamics, which requiresentropy or disorder to increase with time. Cells maintain a stableordered state by generating a steep transmembrane entropy gradientin an open thermodynamic system far from equilibrium through avariety of entropy exchange mechanisms. …”

    Persistent homology based topological analysis on the gestalt patterns during human brain cognition process by Zaisheng LIU, Fei NI, Rongpeng LI, Honggang ZHANG, Chang LIU, Jiefang ZHANG, Songyun XIE

    Published 2021-07-01
    “…The integrated development of information communication technology and neuroscience heralds the possibility and great potential of brain-to-brain wireless communication(B2BC).The physiologically meaningful features of brain responses were extracted to different contour and shape in images in Gestalt cognitive tests by combining persistent homology analysis with electroencephalogram (EEG).The experimental results show that more brain regions in the frontal lobe were involved when the subject perceives the random and disordered combination of images compared to the ordered Gestalt images.Meanwhile, the persistence entropy of EEG data evoked by random sequence diagram (RSD) was observed to be significantly different from that by the ordered Gestalt images(GST) in several frequency bands, which indicated that human cognition of shapes and contours, such as a preliminary advanced cognition process, could be separated to some extent through topological analysis.This method can digitize the neural signals while preserving the whole and local features of the original signals.In general, the cognitively related neural correlates by persistent homology features of EEG signal are revaluated and quantified, which provides an approach to realize the digitization of neural signals in brain-to-brain wireless communication.…”

    Evolution of Bounded Confidence Opinion in Social Networks by Hui Xie, Guangjian Li, Yongjie Yan, Sihui Shu

    Published 2017-01-01
    “…Depending on the fraction of undirected long-range connections, we observe fascinatingly rich dynamical behavior and transitions from disordered to ordered states. In general, we find that the stubborn agent promotes the emergence of consensus due to the so-called “group effect” that facilitates coalescence between separated network components. …”

    Entanglement content of kink excitations by Luca Capizzi, Michele Mazzoni

    Published 2025-02-01
    “…Finally, we discuss some consequences of the Kramers-Wannier duality, which relates the ordered and disordered phases of the Ising model, and we explain why, counterintuitively, no explicit relations between those phases are found at the level of entanglement.…”

    A Meta-Synthesis of the Integrated Model of Customer Value co-Destruction and Value co-Creation by Zohreh Dehdashti Shahrokh, Vahid Nasehifar, Mohammad Reza Karimi Alavijeh, Yazdan Rahmatabadi

    Published 2024-12-01
    “…It should be noted that all the variables appear in both levels, but they show the greatest impact in the mentioned levels.ConclusionIt is very important to keep in mind that the categories of both value creation and destruction have a semantic contradiction, but it is necessary to pay attention to the fact that the creation of customer value co-destruction is unavoidable and the processes tend to increase entropy and disorder. This is also true regarding the co-destruction of customer value and the tendency of the system to create co-destruction is that by identifying the factors that cause co-destruction and curbing them using the appropriate strategy, it will be possible to create co-creation continuously and continuously. …”
