The interest in the influence of videogame experience on our daily life is constantly growing. "First Person Shooter" (FPS) games require players to develop a flexible mindset to rapidly react to fast moving visual and auditory stimuli, and to switch back and forth between different subtasks. This study investigated whether and to which degree experience with such videogames generalizes to othe...

While brain research shows great potential for advancing critical national security interests, the products of the laboratory cannot be realized in operational practice without the polishing and maturing demanded by federal science and technology (S&T) acquisition processes, particularly those of the Department of Defense. Although many acquisition planning functions are relatively conventional...

A s the “baby boomers” approach and enter their retirement years, the accumulation phase of their life-cycle is nearly over. Thus, the focus of many researchers, fi nancial services fi rms, and public policymakers concerned with retirement saving is shifting from the accumulation of resources while working to the drawdown of resources during retirement. Retired households are dependent on the a...

Cognitive flexibility reflects both a trait that reliably differs between individuals and a state that can fluctuate moment-to-moment. Whether individuals can undergo persistent changes in cognitive flexibility as a result of reward learning is less understood. Here, we investigated whether reinforcing a periodic shift in an object selection strategy can make an individual more prone to switch ...

For development of new applications a prototyping system is used that has a high degree of flexibility, also for testing. A method for TAP signal routing is presented which offers full flexibility with respect to Boundary Scan test applications. Especially for those PCBs that are used as prototyping platforms it makes the design-for-testability phase less critical. A comparison is made between ...

We explore the flexibility windows of the 194 presently-known zeolite frameworks. The flexibility window represents a range of densities within which an ideal zeolite framework is stress-free. Here, we consider the ideal zeolite to be an assembly of rigid corner-sharing perfect tetrahedra. The corner linkages between tetrahedra are hard-sphere oxygen atoms, which are presumed to act as freely-r...

In this paper, following a two-stage methodology, the differential quadrature element (DQE) model of a three-story frame structure is updated for the vibration analysis. In the first stage, the mass and stiffness matrices are updated using the experimental natural frequencies. Then, having the updated mass and stiffness matrices, the structural damping matrix is updated to minimize the error be...

Civil infrastructures such as bridges and buildings are prone to damage as a result of natural disasters. To understand damages induced by these events, the structure needs to be monitored. The field of engineering focusing on the process of evaluating the location and the intensity of the damage to the structure is called Structural Health Monitoring (SHM). Early damage prognosis in structures...

We discuss two flexibility metrics for Simple Temporal Networks (STNs): the so-called naive flexibility metric based on the difference between earliest and latest starting times of temporal variables, and a recently proposed concurrent flexibility metric. We establish an interesting connection between the computation of these flexibility metrics and properties of the minimal distance matrix DS ...

It is becoming increasingly apparent that the vast blue expanse of ocean—the last frontier—is not as inexhaustible as it once seemed. While we have yet to fully explore the reaches of the sea, technology has granted humans the ability to harvest its wealth. We can now fi sh anywhere, at any depth, for any species. Like the American frontier range’s bison and wolf populations brought to the brin...
