A Survey on High-Order Internal Model Based Iterative Learning Control by Miao Yu, Sheng Chai

“…HOIM can be formulated as a polynomial in the iteration domain, which is auto-regressive. HOIM-based ILC for nonlinear systems is more complex than HOIM-based ILC for linear systems, and when the system parameters change iteratively, the Lyapunov-based analysis method is used instead of traditional contraction mapping method. …”

Local English teachers’ voices from a marginalized lens: Inequality practices and identity construction in the workplace by Sahril Nur, Ismail Anas, Reski Pilu, Nurfajriah Basri

“… This article reports on a narrative case study that showcases the local English teachers’ perceived inequality practices and identity construction in Indonesia’s micro-reality context of a private language school domain. Grounded in the social theory of power, privilege, and positional identities, three synchronous online interviews were conducted to explore the LETs voices about what it means to experience the equality of rights and obligations in the workplace. …”

Charge Order Breaks Magnetic Symmetry in Molecular Quantum Spin Chains by M. Dressel, M. Dumm, T. Knoblauch, B. Köhler, B. Salameh, S. Yasin

“…The coupling of anions and organic molecules rotates the g-tensor out of the molecular plane creating magnetically nonequivalent sites on neighboring chains at domain walls. Due to anisotropic Zeeman interaction a novel magnetic interaction mechanism in the charge-ordered state is observed as a doubling of the rotational periodicity of ΔH.…”
