Dangerous rock masses in mountainous areas seriously threaten the construction and operation of engineering with potential disaster hazards, especially the unpredictability and sudden occurrence of rockfall, which poses a huge challenge. This paper presents a systematic risk assessment and disposal of high and steep giant dangerous rock masses, which can pose a serious threat to railway operation. Using comprehensive methods such as on-site investigation, limit equilibrium method, and simulation analysis of rockfall trajectory, the possibility and potential harm of collapse and rockfall of giant dangerous rock masses are analyzed and corresponding remediation measures are proposed.

Robotics holds the potential to streamline the execution of repetitive and dangerous tasks, which are difficult or impossible for a human operator. However, in complex scenarios, such as nuclear waste management or disaster response, full automation often proves unfeasible due to the diverse and intricate nature of tasks, coupled with the unpredictable hazards, and is typically prevented by stringent regulatory frameworks. Consequently, the predominant approach to managing activities in such settings remains human teleoperation.

Mentally ill offenders face stigma, being perceived as both dangerous and unpredictable. This leads to social discrimination, which causes devaluation, distancing, and unequal treatment towards them. Critical and dismissive attitudes of healthcare professionals and police toward these patients undermine their care, treatment, and prospects for rehabilitation.

Introduction: It has been shown that public stigma towards people with schizophrenia hinders their psychosocial integration. Public stigma expresses itself through lexical labels used in the print media and social networks, heightening the internalization of stigma in this population, a phenomenon known as internalised stigma or self-stigma. This paper analyses the diffusion in the mass media of two dimensions of stigma: public stigma and self-stigma.

Defensive behavior changes based on threat intensity, proximity, and context of exposure, and learning about danger-predicting stimuli is critical for survival. However, most Pavlovian fear conditioning paradigms focus only on freezing behavior, obscuring the contributions of associative and non-associative mechanisms to dynamic defensive responses. To thoroughly investigate defensive ethograms, we subjected male and female adult C57BL/6 J mice to a Pavlovian conditioning paradigm that paired footshock with a serial compound stimulus (SCS) consisting of distinct tone and white noise (WN) stimulus periods.
