    Exploring quantum control landscape and solution space complexity through optimization algorithms and dimensionality reduction

    We can study the QCL generated when using SGD, GA, QL, DQN and PPO for N-parameter optimization using (5). In order to generate the QCLs as a function of fidelity, we run 1000 experiments for each algorithm, hence generated 1000 data-points, we…

  • Nonlinear oscillations of a lumped system with series spring, piezoelectric device, and feedback controller

    Nonlinear oscillations of a lumped system with series spring, piezoelectric device, and feedback controller

    In this section, the MSM is used to obtain the AS of the previously provided system of Eqs. (5)-(7). Therefore, we focus our study on the dynamic behavior of this system in a narrow region bounded by the static equilibrium point34. Then, the…

  • Astaxanthin supplementation in Arabian racing horses mitigates oxidative stress and inflammation in peripheral blood mononuclear cells through enhanced mitophagy

    Astaxanthin supplementation in Arabian racing horses mitigates oxidative stress and inflammation in peripheral blood mononuclear cells through enhanced mitophagy

    Evaluation of the in vitro protective effect of astaxanthin against oxidative stress in horse-derived PBMCs

    As shown at Fig. 1.A, treatment with H2O2 (oxidative stress condition, OS) increased the number of ROS-positive cells, while decreased the…

  • Community evolution prediction based on feature change patterns in social networks

    Community evolution prediction based on feature change patterns in social networks

    This paper proposes a prediction method to characterize the pattern of community feature changes, learn their impact on evolutionary events, and forecast critical events in the next timeframe. In this section, we will analyze the effectiveness of…

  • Appearance and disappearance, an unrecognized form of grouping and form perception from common fate

    Appearance and disappearance, an unrecognized form of grouping and form perception from common fate

    In 1923, more than one hundred years ago, Max Wertheimer1 described a variety of laws of perceptual organization, including such important factors as proximity, similarity, and closure. One important factor that could sometimes compete with and…

    Fast high-resolution lifetime image reconstruction for positron lifetime tomography

    PLI event model

    In this paper, a PLI event is defined as a triple coincidence consisting of two annihilation photons and a prompt gamma. It is mathematically represented by a TOF sinogram bin \({i}_{k}\) determined by the LOR and the TOF bin of…

  • Investigation of sestrin-2 levels and thiol-disulfide homeostasis in polyp tissue of patients with nasal polyps

    Investigation of sestrin-2 levels and thiol-disulfide homeostasis in polyp tissue of patients with nasal polyps

    Although the causes of nasal polyposis are multifactorial, inflammation is one of the most important factors in the development of NP. The presence of inflammatory cells such as eosinophils, neutrophils, lymphocytes, and macrophages indicates the…
