Considering the vulnerability of double-layer grid space structures to progressive collapse phenomenon, it is necessary to pay special attention to this phenomenon in the design process. Alternate path method is one of the most appropriate and accepted methods for progressive collapse resistant design of structures. Alternate Path Method permits local failure to occur but provides alternate pat...

Using molecular dynamics with an accurate many-body potential, we studied the rapid expansion of Ta metal following the high compression ~50 to 100 GPa! induced by high velocity (2 to 4 km/s! impact. We find that catastrophic failure in this system coincides with a critical behavior characterized by a void distribution of the form N(v)}V, with t;2.2. This corresponds to a threshold in which per...

Mixtures of increasing failure rate distributions (IFR) can decrease at least in some intervals of time. Usually this property is observed asymptotically as ∞ → t , which is due to the fact that a mixture failure rate is ‘bent down’, as the weakest populations are dying out first. We consider a survival model, generalizing a very well known in reliability and survival analysis additive hazards,...

Ple doi Dialectical behavior therapy (DBT) has become a widely used treatment model for individuals with borderline personality disorder (BPD) and other individuals with significant emotion dysregulation problems. Despite its strong empirical support, DBT obviously does not have positive outcomes for all individuals. It is critical that cases of DBT nonresponse be analyzed so that further treat...

In this paper we articulate theoretical bases for robust behavior composition of multiple modules (e.g., agents, devices, etc.) by relying on the formal notion of simulation. Specifically, we consider the problem of synthesizing a fully controllable target behavior from a library of available partially controllable behaviors that are to execute within a shared, fully observable, but partially p...

The dynamic interplay between reflexive and controlled determinants of behavior is one of the most general organizing principles of brain function. A powerful analogue of this interplay is seen in the antisaccade task, which pits reflexive and willed saccadic mechanisms against one another. Event-related functional magnetic resonance imaging of the human brain showed greater prestimulus prepara...
