Advanced Science, EarlyView.Photonic time crystals (PTCs) are systems in which electromagnetic parameters are modulated periodically in time, producing momentum bandgaps via temporal scattering rather than spatial Bragg processes. This review examines the theoretical frameworks, modeling, and computational tools for time‐varying media, and summarizes experimental demonstrations ...

Fusion Algebras and Differential Equation Approach to Rational Conformal Field Theories
, 1990 Constraints on conformal dimensions and central charge of Rational Conformal Field Theories (RCFTs) coming from analytic closure of 4-point functions on the sphere and modular invariance of partition function on the torus are reviewed. These constraints,

Celestial sector in CFT: Conformally soft symmetries
SciPost PhysicsWe show that time intervals of width $\Delta \tau$ in 3-dimensional conformal field theories (CFT$_3$) on the Lorentzian cylinder admit an infinite dimensional symmetry enhancement in the limit $\Delta \tau → 0$.

Advanced Science, EarlyView.The present study shows that Nrf2 directly binds to the Gm26550 promoter, thereby activating Gm26550 transcription and increasing its expression. Mechanistically, Gm26550 promotes IGF1 expression by functionally antagonizing miR‐26a‐5p‐mediated repression and sequestering the RBP KHSRP, thereby enhancing hippocampal neuronal synaptic plasticity and ...

Advanced Science, EarlyView.Deep‐learning‐based signal enhancement is an effective way to recover high‐resolution details from a low‐resolution chromatin contact map. However, due to computational challenges, existing methods commonly divide up the contact map into small patches and create artificial discontinuities at patch boundaries.

Holomorphically Planar Conformal Vector Fields on almost Hermitian Manifolds
, 2003 We introduce the notion of a holomorphically planar conformal vector (HPCV) field on an almost Hermitian manifold. First we generalize a result of Goldberg, showing that an HPCV on a Kaehler manifold is homothetic and analytic.
