A Proposal for Constraining Initial Vacuum by CMB
, 2017 We propose a theoretical framework that can possibly constrain the initial vacuum by Cosmic Microwave Background (CMB) observations. With a generic vacuum without any particular choice a priori, thereby keeping both the Bogolyubov coefficients in the ...

Advanced Science, EarlyView.This study combines full‐field tomography with diffraction mapping to quantify radial (ε002$\varepsilon _{002}$) and axial (ε100$\varepsilon _{100}$) lattice strain in wrinkled carbon‐fiber specimens for the first time. Radial microstrain gradients (−14.5 µεMPa$\varepsilon \mathrm{MPa}$−1) are found to signal damage‐prone zones ahead of failure, which ...

Historical notes concerning three attempts to normalize relations between Cuba and the United States
Universidad Médica Pinareña, 2018 Introduction: many researchers have been conducted, both by Cuban and foreign authors, who have addressed US policy towards Cuba since 1959, but most of these analyses, have addressed a common theme: the aggressive factor, sometimes ignoring the steps ...

Generalization of Einstein-Lovelock theory to higher order dilaton gravity
, 2007 A higher order theory of dilaton gravity is constructed as a generalization of the Einstein-Lovelock theory of pure gravity. Its Lagrangian contains terms with higher powers of the Riemann tensor and of the first two derivatives of the dilaton ...

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 ...

Hierarchical Artificial Muscle with Nonlinear Elasticity for Antagonistic and Cyclic Robotics
Advanced Science, EarlyView.We construct hierarchical muscles by plying nylon fibers around a heating wire. The hierarchical muscle shows a J‐shaped passive curve, which shows benefit in antagonistic muscle pair and work accumulation mechanism. We also develop a computational, first‐principle model to understand the physics of both active actuation stroke and passive J‐curve ...

Special functions with mod n symmetry and kaleidoscope of quantum coherent states
, 2018 The set of mod $n$ functions associated with primitive roots of unity and discrete Fourier transform is introduced. These functions naturally appear in description of superposition of coherent states related with regular polygon, which we call ...
