Abstract When a rock mass shears along a joint surface, the shear resistance is affected by joint surface undulations and friction between the contact regions. During an earthquake, the seismic load causes dynamic deterioration of the joint surface m

The mechanism of seismic-induced bedding rock landslide is distinct from that of slope instability/landslide in normal gravity conditions; their failure modes are mainly characterized by vibration deterioration effect of rock mass structural plane du

In view of the Tanjiawan landslide, which occurred in the northwest of Zigui County in May 2016, this paper preliminarily defined the affected area, characteristics and occurrence time sequence of the landslide based on multi-source data such as sate

The earthquake-induced permanent displacement is an important index of the potential damage to a slope during an earthquake. The Newmark method assumes that a slope is a rigid-plastic body, and the seismic responses of sliding masses or seismic force

To solve such problems as insufficient illumination improvement and unnatural visual effects in the existing dark image enhancement approaches, we propose a Bezier curve-based and saturation-aided dark image enhancement method with image fusion. Firs

Background The diagnosis of microinvasive laryngeal squamous cell carcinoma (LSCC) is not always straightforward and sometimes can be very challenge in daily clinical practice. The focus lies in the confirmation of microinvasion. Cancer-associated fi
