This paper presents the mathematical conditions and the associated design methodology of an active fault diagnosis technique for continuous-time linear systems. Given a set of faults known a priori, the system is modeled by a finite family of linear time-invariant systems, accounting for one healthy and several faulty configurations. By assuming bounded disturbances and using a residual generator,
We consider flow-inducing networks, a class of models that are well-suited to describe important biochemical systems, including the MAPK pathway and the interactions at the trans-Golgi network. A flow-inducing network is given by the interconnection of subsystems (modules), each associated with a stochastic state matrix whose entries depend on the state variables of other modules. This results in
Slotted wing tips of birds are commonly considered an adaptation to improve soaring performance, despite their presence in species that neither soar nor glide. We used particle image velocimetry to measure the airflow around the slotted wing tip of a jackdaw (Corvus monedula) as well as in its wake during unrestrained flight in a wind tunnel. The separated primary feathers produce individual wakes
This study investigated the effects of cognitive conflict on abstract thinking. According to action-identification theory, an ambiguous and unfamiliar situation might propel an individual to a more abstract mindset. Based on this premise, cognitive conflict was hypothesized to put people in an abstract mindset. The induced compliance paradigm, in which participants are asked to write a counter-att
This Note introduces the Heads of Government dataset, which provides summary information about the ideological orientation of heads of government (left, center, or right, with separately provided information about religious orientation) in 33 states in Western Europe, the Americas, and the Asia–Pacific region between 1870 and 2012. The Note also describes some intriguing empirical patterns when it
This article builds on recent works on witnessing, socially engaged documentary filmmaking and studies on the role of new digital technologies for witnessing trauma, recording memories and enabling activism. In a devastating earthquake in Sichuan province on 12 May 2008, almost 90,000 people, at least 5000 of them being children, died. Parents and bystanders provided the first footage of the earth

Two areas are covered in the two cohorts, respectively; the assessment of mortality, prognosti
