Competition between Kardar-Parisi-Zhang and Berezinskii-Kosterlitz-Thouless kinetic roughening on (001) singular surface during steady crystal growth.

Kinetic roughening of the (001) singular surface during steady crystal growth is studied on the basis of a lattice model using the Monte Carlo method. At a sufficiently low temperature, there are known to be two kinetic roughening points as the driving force for crystal growth increases. At a low driving force , there is the Karder-Parisi-Zhang (KPZ) roughening transition point.

Postoperative Symptomatic Cerebral Vasospasm: Requiring Attention Following an Uneventful Resection of an Epidermoid Cyst - A Case Report and Literature Review.

Cerebral vasospasm associated with epidermoid cyst can be caused by tumor content spillage, such as spontaneous rupture and postsurgical resection. Symptomatic cerebral vasospasm following the resection of an intracranial epidermoid cyst is a rare but serious complication that lacks a consensus on treatment. Case presentation: A 10-year-old girl underwent an uneventful complete resection of a left cerebellopontine angle epidermoid cyst.

Fractal geometry of culprit coronary plaque images within optical coherence tomography in patients with acute coronary syndrome vs stable angina pectoris.

The main cause of acute coronary syndrome (ACS) is plaque rupture and thrombus formation. However, it has not been fairly successful to identify vulnerable plaque to rupture using conventional parameters of intravascular imaging modalities. Fractal analysis is one of the mathematical models to examine geometrical features of picture image using a specific parameter called as fractal dimension (FD) which suggests geometric complexity of the image.
