Concentrations and health risk assessment of 24 residual heavy metals in Chinese mitten crab (Eriocheir sinensis)

open access: yesQuality Assurance and Safety of Crops & Foods, 2022
In this study, a total of 135 Chinese mitten crab (Eriocheir sinensis) samples were collected from four major crab-producing provinces (Jiangsu, Hubei, Anhui, and Liaoning) in China.

The Chinese mitten crab genome provides insights into adaptive plasticity and developmental regulation

open access: yesNature Communications, 2021
The infraorder Brachyura (true or short-tailed crabs) represents a successful group of marine invertebrates yet with limited genomic resources. Here we report a chromosome-anchored reference genome and transcriptomes of the Chinese mitten crab Eriocheir ...

Observation of the Crab Nebula with LHAASO-KM2A − a performance study *

open access: yesChinese Physics C, High Energy Physics & Nuclear Physics, 2020
As a sub-array of the Large High Altitude Air Shower Observatory (LHAASO), KM2A is mainly designed to cover a large fraction of the northern sky to hunt for gamma-ray sources at energies above 10 TeV.

Observation of the Crab Nebula with the HAWC Gamma-Ray Observatory [PDF]

open access: yes, 2017
The Crab Nebula is the brightest TeV gamma-ray source in the sky and has been used for the past 25 years as a reference source in TeV astronomy, for calibration and verification of new TeV instruments. The High Altitude Water Cherenkov Observatory (HAWC),

Chromosome-level assembly of the horseshoe crab genome provides insights into its genome evolution

open access: yesNature Communications, 2020
The evolutionary history of horseshoe crabs, spanning approximately 500 million years, is characterized by remarkable morphological stasis and a low species diversity with only four extant species.

Searching for gravitational waves from the Crab pulsar - the problem of timing noise [PDF]

open access: yes, 2003
Of the current known pulsars, the Crab pulsar (B0531+21) is one of the most promising sources of gravitational waves. The relatively large timing noise of the Crab causes its phase evolution to depart from a simple spin-down model.

Measurement of Crabs [PDF]

open access: yesNature, 1896
MR. CUNNINGHAM, in NATURE of October 29, raises a doubt as to the trustworthiness of the results of my measurements of crabs, on the ground that the specimens of the year 1893 had been longer in spirit than those of 1895.
