Dynamically controlling terahertz (THz) wavefronts in a designable fashion is highly desired practice. However, available methods working at microwave frequencies do not work well the THz regime due to lacking suitable tunable elements with submicrometer sizes. Here, instead of locally individual meta-atoms metasurface, we show that rotating different layers (each exhibiting particular phase profile) cascaded metadevice speeds can dynamically change effective Jones-matrix property whole...

Abstract Dynamical controls on terahertz (THz) wavefronts are crucial for many applications, but available mechanism requests tunable elements with sub-micrometer sizes that difficult to find in the THz regime. Here, different from local-tuning mechanism, we propose an alternative approach construct wavefront-control meta-devices combining specifically designed metasurfaces and globally tuned graphene layers. Coupled-mode-theory (CMT) analyses reveal serves as a loss drive whole meta-device...

Abstract Spin‐controlled vortex generation and spin‐Hall effect, two distinct effects discovered in optics, have been extensively studied recently. However, while physical origins of are both due to spin‐orbit interactions, their inherent connections remain obscure which also hinders further explorations on the manipulations them. Here, studying scattering a spin‐polarized light beam at sharp interfaces, an intriguing phase transition between shift trigged by varying incidence angle is...

Neural tissue engineering techniques typically face a significant challenge, simulating complex natural vascular systems that hinder the clinical application of tissue-engineered nerve grafts (TENGs). Here, we report subcutaneously pre-vascularized TENG consisting endothelial growth factor-induced host network, chitosan conduit, and inserted silk fibroin fibers. Contrast agent perfusion, clearing, microCT scan, blood vessel 3D reconstruction were carried out continuously to prove whether...

Conventional optical devices that generate focused vortex beams (FVBs) often suffer from bulky size and integration challenges with other components. Here, we propose a novel approach using transmission-type Pancharatnam-Berry (PB) meta-surface to nearly perfect terahertz opposite incident circular polarization. Our design leverages silicon pillars composed of two-layer structures exhibiting symmetry Fabry-Perot resonances along two orthogonal directions, serving as high performance...

Endothelial cells have important biological roles after peripheral nerve injury by forming blood vessels within the gap and guiding Schwann cell migration. MicroRNAs (miRNAs/miRs) affect cellular behavior regulate a wide variety of physiological pathological activities, including regeneration. Emerging studies identified essential miRNAs in phenotype modulation cells, while effects on endothelial remained to be thoroughly investigated. miR‑328a‑3p was differentially expressed stumps injury....

Sequence recommendation algorithms using self-supervised learning models usually use the same encoder to generate different embedding vectors of original sequences, which can easily lead lack information they carry and formation collapse. Meanwhile, when model pays too much attention data details noise, it will a decrease in performance insufficiently accurate results. Aiming at above problems, this paper proposes sequence algorithm based on an enhanced encoder. Firstly, enhancement methods...
