This rhythm is naturally prominent in the hippocampus during exploratory behaviour and can be subdivided into high theta (8 12 Hz), which is dependent on motor activity [14], [15], [16], and low theta (5 8 Hz), which is triggered by medial septum activation [14], [17].
These can be subdivided into high-silica peraluminous granites and low-silica metaluminous granodiorites, and all belong to the high-K calc-alkaline series, are enriched in LILE, and depleted in HFSE.
In terms of dip angles, tectonic fractures can be subdivided into high-angle fracture with a dip angle of more than 70° and approximately horizontal fracture with a dip angle of 10° 30° (Fig. 6).
The serous subtypes can be subdivided into high-grade (75%) and low-grade serous epithelial ovarian cancer (25%) [ 1].
UAPI was subdivided into high- and low-risk categories for MTX-R using a cut of ⩽1 and >1, defined in our previous study based on ROC curve analysis (Agarwal et al, 2002).
To analyze the association of OS and PFS with angiogenesis-related protein expression, patients were subdivided into high or low-expression groups based on the median cut-off values.
Type 2 VHL disease shows a high risk of pheochromocytoma (PCC) and germ line missense mutations is subdivided into high risk (2B), low risk (2A), or absence (2C) of Renal cell carcinoma (RCC) and heamangioblastoma is correlated with function of pVHL to impair HIF-1α activity [ 1, 2].
Those strains of HPV associated with genital tract infection are subdivided into high- and low-risk types, and of the former HPV 16 and 18 are estimated to be responsible for over 70% of all cases of cervical cancer (Howell-Jones et al, 2010).
The families were subdivided into high risk when multiple cases of breast and ovarian cancer were diagnosed, medium risk if there were only 2 3 cases of breast cancer, and low risk in isolated cases of breast cancer with diagnosis before the age of 40 years.
These tumors are subdivided into high-grade and low-grade serous carcinomas [6].
In addition, clinical tumor volume (CTV) can be subdivided into CTV1 (high-risk subclinical disease) and CTV2 (low-risk subclinical disease), though the optimal delineation has not been determined.
