Scar-centered dilation in the treatment of large keloids.

Background: Hypertrophic scars and keloid treatment is a major problem in plastic surgery. While small keloids can be treated with resection followed by radiotherapy, large keloids require treatment with a tissue expander. Conventional methods increase the need for auxiliary incisions, causing new scar hyperplasia.

Magnetoencephalography for epileptic focus localization based on Tucker decomposition with ripple window.

Aims: To improve the Magnetoencephalography (MEG) spatial localization precision of focal epileptic.

Methods: 306-channel simulated or real clinical MEG is estimated as a lower-dimensional tensor by Tucker decomposition based on Higher-order orthogonal iteration (HOOI) before the inverse problem using linearly constraint minimum variance (LCMV). For simulated MEG data, the proposed method is compared with dynamic imaging of coherent sources (DICS), multiple signal classification (MUSIC), and LCMV.
