    Singularity-Free Neural Control for the Exponential Trajectory Tracking in Multiple-Input Uncertain Systems with Unknown Deadzone Nonlinearities by J. Humberto Pérez-Cruz, José de Jesús Rubio, Rodrigo Encinas, Ricardo Balcazar

    Published 2014-01-01
    “…The trajectory tracking for a class of uncertain nonlinear systems in which the number of possible states is equal to the number of inputs and each input is preceded by an unknown symmetric deadzone is considered. The unknown dynamics is identified by means of a continuous time recurrent neural network in which the control singularity is conveniently avoided by guaranteeing the invertibility of the coupling matrix. …”

    Validity of black hole complementarity in an accelerating Schwarzschild black hole by Wontae Kim, Mungon Nam

    Published 2025-02-01
    “…Black hole complementarity has been well understood in spherically symmetric black holes. To study its validity for an accelerating Schwarzschild black hole, which has a preferred direction, we perform the thought experiment proposed by Susskind and Thorlacius and further investigate the criteria set by Hayden and Preskill. …”

    TBA equations and quantum periods for D-type Argyres-Douglas theories by Katsushi Ito, Jingjing Yang

    Published 2025-01-01
    “…We study the variety of TBA systems across the Coulomb branch moduli space and find that they correspond to the Dynkin diagrams of D n Lie algebras in the minimal chamber, and reproduce the TBA equations for reflectionless D scattering theories at the maximally symmetric point. Numerical computations demonstrate that the quantum periods obtained from the Borel-Padé resummation and their WKB expansions are in agreement with the solutions of the TBA equations.…”

    Spectroscopic Characteristics and Color Origin of Red Tourmaline from Brazil by Ming Li

    Published 2022-01-01
    “…The results showed that the red color was confirmed by the symmetric broad absorption at 527 nm and the narrow absorption at 400 and 450 nm, and the above three absorption bands were caused by the d-d electron transition of Mn3+, which occupied the Y site in the crystal structure and coordinated with F to form bonds. …”

    The Strip-Ground Rectangular Patch Antenna by Yiying Wang, Yinghua Lu

    Published 2017-01-01
    “…To imitate the broken situation of the conductive threads of the wearable antenna, a strip-ground design of rectangular patch antenna with the conventional substrate is presented to investigate the change of the antenna performance, where the ground is sliced along its E-plane. The strips are symmetrical along the center line of the width of the patch, and the gap ratio of the gap to the solid ground varies with the change of gaps. …”

    A compact theorem on the compactness of ultra-compact objects with monotonically decreasing matter fields by Shahar Hod

    Published 2025-02-01
    “…In the present compact paper we raise the following physically interesting question: Is there a lower bound on the global compactness parameters $$\mathcal{C}\equiv \text {max}_r\{2m(r)/r\}$$ C ≡ max r { 2 m ( r ) / r } of spherically symmetric ultra-compact objects? Using the non-linearly coupled Einstein-matter field equations we explicitly prove that spatially regular ultra-compact objects with monotonically decreasing density functions (or monotonically decreasing radial pressure functions) are characterized by the lower bound $$\mathcal{C}\ge 1/3$$ C ≥ 1 / 3 on their dimensionless compactness parameters.…”
