Discrete Multi-Graph Clustering.
Luo M, Yan C, Zheng Q, Chang X, Chen L, Nie F. Luo M, et al. IEEE Trans Image Process. 2019 Apr 30. doi: 10.1109/TIP.2019.2913081. Online ahead of print. IEEE Trans Image Process. 2019. PMID: 31056498
Unfortunately, directly optimizing the spectral clustering inevitably results in an NP-hard problem due to the discrete constraints on the clustering labels. Hence, conventional approaches intuitively include a relax-and-discretize strategy to approximate the origin …

Discrete Optimal Graph Clustering.
Han Y, Zhu L, Cheng Z, Li J, Liu X. Han Y, et al. IEEE Trans Cybern. 2020 Apr;50(4):1697-1710. doi: 10.1109/TCYB.2018.2881539. Epub 2018 Dec 7. IEEE Trans Cybern. 2020. PMID: 30530347
Most of it works in three separate steps: 1) similarity graph construction; 2) clustering label relaxing; and 3) label discretization with k -means (KM). Such common practice has three disadvantages: 1) the predefined similarity graph is often fixed and may not be optimal …

Discrete sampling in perception via neuronal oscillations-Evidence from rhythmic, non-invasive brain stimulation.
Kasten FH, Herrmann CS. Kasten FH, et al. Eur J Neurosci. 2022 Jun;55(11-12):3402-3417. doi: 10.1111/ejn.15006. Epub 2020 Nov 3. Eur J Neurosci. 2022. PMID: 33048382
A variety of perceptual phenomena suggest that, in contrast to our everyday experience, our perception may be discrete rather than continuous. The possibility of such discrete sampling processes inevitably prompts the question of how such discretization is im …

Discrete cyclic systems and circle congruences.
Hertrich-Jeromin U, Szewieczek G. Hertrich-Jeromin U, et al. Ann Mat Pura Appl. 2022;201(6):2797-2824. doi: 10.1007/s10231-022-01219-5. Epub 2022 May 10. Ann Mat Pura Appl. 2022. PMID: 36277432 Free PMC article.
We discuss integrable discretizations of 3-dimensional cyclic systems, that is, orthogonal coordinate systems with one family of circular coordinate lines. In particular, the underlying circle congruences are investigated in detail and characterized by the existence of a c …

Novel Discrete-Time Recurrent Neural Network for Robot Manipulator: A Direct Discretization Technical Route.
Shi Y, Zhao W, Li S, Li B, Sun X. Shi Y, et al. IEEE Trans Neural Netw Learn Syst. 2023 Jun;34(6):2781-2790. doi: 10.1109/TNNLS.2021.3108050. Epub 2023 Jun 1. IEEE Trans Neural Netw Learn Syst. 2023. PMID: 34524961
However, such model usually originates from the discretization research of continuous time-variant problem, and there is little research on the direct discretization method. To address the aforementioned problem, this article introduces a novel discrete-time …

Discrete spectral eigenmode-resonance network of brain dynamics and connectivity.
Robinson PA. Robinson PA. Phys Rev E. 2021 Sep;104(3-1):034411. doi: 10.1103/PhysRevE.104.034411. Phys Rev E. 2021. PMID: 34654199
Because these modal resonances are determined by the system dynamics, not the investigator, they are privileged over widely used phenomenological patterns, and obviate the need for artificial discretizations and thresholding in coordinate space. It is shown that modal reso …

Discrete-Time Memristor Model for Enhancing Chaotic Complexity and Application in Secure Communication.
Yan W, Dong W, Wang P, Wang Y, Xing Y, Ding Q. Yan W, et al. Entropy (Basel). 2022 Jun 23;24(7):864. doi: 10.3390/e24070864. Entropy (Basel). 2022. PMID: 35885087 Free PMC article.
The physical implementation of the continuous-time memristor makes it widely used in chaotic circuits, whereas the discrete-time memristor has not received much attention. In this paper, the backward-Euler method is used to discretize the TiO2 memristor model, and t …

Characterization of Bond Fracture in Discrete Groove Wear of Cageless Ball Bearings.
Zhao Y, Jin Y, Pan C, Wu C, Yuan X, Zhou G, Han W. Zhao Y, et al. Materials (Basel). 2022 Sep 27;15(19):6711. doi: 10.3390/ma15196711. Materials (Basel). 2022. PMID: 36234053 Free PMC article.
Once worn, the discrete groove can cause the rolling element to discretely fail. This paper presents the discrete element method to investigate the wear of discrete grooves in cageless bearings from the standpoint of bond fracture. In conjunction with …

Asymptotics of the Determinant of Discrete Laplacians on Triangulated and Quadrangulated Surfaces.
Izyurov K, Khristoforov M. Izyurov K, et al. Commun Math Phys. 2022;394(2):531-572. doi: 10.1007/s00220-022-04437-3. Epub 2022 Jul 30. Commun Math Phys. 2022. PMID: 35992732 Free PMC article.
Consider a surface omega with a boundary obtained by gluing together a finite number of equilateral triangles, or squares, along their boundaries, equipped with a vector bundle with a flat unitary connection. Let omegadelta be a discretization of this surface, in which eac …

Discrete stochastic analogs of Erlang epidemic models.
Getz WM, Dougherty ER. Getz WM, et al. J Biol Dyn. 2018 Dec;12(1):16-38. doi: 10.1080/17513758.2017.1401677. J Biol Dyn. 2018. PMID: 29157162 Free PMC article.
Here we formulate discrete-time deterministic analogs of the Erlang models, and their stochastic extension, based on a time-to-go distributional principle. Depending on which distributions are used (e.g. discretized Erlang, Gamma, Beta, or Uniform distributions), we …
