Bioinspired twist-hyperbolic metamaterial for impact buffering and self-powered real-time sensing in UAVs.

Turbulence-induced vibrations pose substantial risks to aircraft structural integrity and flight stability, particularly in unmanned aerial vehicles (UAVs), where real-time impact monitoring and lightweight protection are critical. Here, we present a bioinspired twist-hyperbolic metamaterial (THM) integrated with a triboelectric nanogenerator (TENG) for simultaneously impact buffering and self-powered sensing. The THM-TENG protector exhibits tunable stiffness (40 to 4300 newtons per millimeter), ~70% impact energy absorption, and achieves a specific energy absorption of ~0.

Reproductive Biology of (Perciformes: Sciaenidae) in Fujian Waters, Southern China.

is a newly described species from the Family Sciaenidae (Perciformes). The species is commonly found in shallow coastal waters along both sides of the Taiwan Strait, on the west sides of Zhejiang, Fujian, Guangdong and Hong Kong and east side of Taiwan, and has been misidentified for decades. We studied the reproductive biology of from Fujian coastal waters, southern China, using gonadosomatic index (GSI) and gonad histology analyses.

Complete mitochondrial genome and the phylogenetic position of the tigertooth croaker (Perciformes: Sciaenidae).

In this study, the complete mitogenome of the tigertooth croaker was first determined. This mitogenome is 16,589 bp in length, and consists of 37 genes with the typical gene order and direction of transcription in vertebrates. The overall nucleotide composition is: 27.

Complete mitochondrial genome and the phylogenetic position of the bighead pennah croaker (Perciformes: Sciaenidae).

The complete mitogenome of the bighead pennah croaker was first determined in this study. It is 16,508 bp in length with the typical gene order and transcriptional direction in vertebrates containing 37 genes. The overall nucleotide composition is 27.
