SOX2 is an oncogenic transcription factor overexpressed in nearly half of the basal-like triple-negative breast cancers associated with very poor outcomes. Targeting and inhibiting SOX2 is clinically relevant as high SOX2 mRNA levels are positively correlated with decreased overall survival and progression-free survival in patients affected with breast cancer. Given its key role …

abundance of quartz- and flintpebbles are found in the gravel. Symptoms of weathering, soil formation and silica accumulation are observed both in the Basal gravel complex and in the underlying older formations. These interrelated phenomena constitute a distinct feature of the Late Tertiary peneplain. Fig. 1 (left).

Abstract. Viscous flow in ice is often described by the Glen flow law – a non-Newtonian, power-law relationship between stress and strain rate with a stress exponent n ∼ 3. The Glen law is attributed to grain-size-insensitive dislocation creep; however, laboratory and field studies demonstrate that deformation in ice can be strongly dependent on grain size.
