Abstract In this paper we construct a class of Degenerate Higher-Order Scalar-Tensor (DHOST) theories with an extra scalar field, which admits viable solutions of bouncing universe satisfying the following requirements: (i) absence of Belinski-Khalatnikov-Lifshitz (BKL) instability, ghost and gradient instability, (ii) absence of superluminality, (
Trench-Assisted Multicore Fiber with Single Supermode Transmission and Nearly Zero Flattened Dispersion
A trench-assisted multicore fiber (TA-MCF) with single-supermode transmission and nearly zero flattened dispersion is proposed herein.By adding a simplified microstructure cladding with only one ring of low-index inclusions on the basis of the multicore fiber, the microstructure cladding and mode-coupling mechanism were jointly employed into the TA
Spatial-Temporal Differences in the Effect of Epidemic Risk Perception on Potential Travel Intention: A Macropsychology-Based Risk Perception Perspective
Most of the previous studies on the impact of risk perception on travel intention are based on an individual psychological perspective, and the understanding based on the perspective of macropsychology is insufficient.Analyzing the temporal and spatial characteristics of risk perception theory at the macropsychological and regional levels will expa
NFIA determines the cis-effect of genetic variation on Ucp1 expression in murinethermogenic adipocytes
Summary: Thermogenic brown and beige adipocytes counteract obesity by enhancing energy dissipation via uncoupling protein-1 (Ucp1).However, the effect Everything Else of genetic variation on these cells, a major source of disease susceptibility, has been less well studied.Here we examined beige adipocytes from obesity-prone C57BL/6J (B6) and obesit
