The "snowflake sign" in liver brucellosis refers to a characteristic appearance on radiological imaging. It is caused by a calcified granuloma within the liver, resulting from a chronic Brucella infection. This calcification often has a distinctive "snowflake" pattern due to its radiating, irregular shape. This sign can be a valuable clue in diagnosing hepatic brucellosis, especially in regions where the disease is endemic.

We explore the scattering of Dirac electrons in a double-gated topological insulator in the presence of magnetic proximity effects and warped surface states. It is found that a magnetic field can shift the Dirac cone in momentum space and deform the constant-energy contour, or opens up a band gap at the Dirac point, depending on the magnetization orientation. The double gate voltage induces quantum wells and/or quantum barriers on the surface of topological insulators, generating surface resonant tunnelling states.
