Security researchers and practitioners lack techniques to quantitatively evaluate the strength of security systems against a determined attacker. Currently, evaluation is either qualitative, such as through security certification standards, or ad-hoc, such as through penetration testing and auditing. In this paper, we propose a framework that if applied to security systems, would produce quanti...

On many volcanoes, there is evidence of a relationship between dome collapse and periods of high precipitation. We propose a mechanism for this relationship and investigate the conditions that optimize failure by this process. Observations of elongate lobes that evolve through exogenous growth of lava domes reveal that they commonly develop tensile fractures perpendicular to the direction of mo...

Because of the deficiency lymphatic reflux in tumor, retention tumor interstitial fluid causes aggravation pressure (TIP), which leads to unsatisfactory penetration nanomedicine. It is main inducement recurrence and metastasis. Herein, we design a pyroelectric catalysis-based Nano-lymphatic decrease TIP for enhanced treatments. realizes photothermal therapy decomposition under NIR-II laser irra...

pits, quarries, and on construction sites. The prediction of the penetration rate of drilling machines is very important for cost estimation and planning of rock excavation projects. Many researchers have investigated percussive drilling theoretically or experimentally and correlated the penetration rate with various rock properties. Protodyakonov (1962) developed drop tests and described the c...
