One of the most sweeping changes ever in the ecology of human cognition may be taking place today. People are beginning to learn and use very powerful and sophisticated information processing technology as a matter of daily life. From the perspective of human history, this could be a transitional point dividing a period when machines merely helped us do things from a period when machines will s...

Parametric zones are obtained where the cross-flow instability can be identified as a mode in three-dimensional boundary layers with Mach number ranging from 0 to 10. Although term is widely used investigations on boundary-layer instability, previous work [Z. Liu, Phys. Fluids 34, 094110 (2022)] has demonstrated that cannot designated certain circumstances. The identification of significant not...

This study used 20-year records of stream channel change and wood to test hypotheses about the long-term influence of large woody debris (LWD) on channel morphology, channel stability, and sediment dynamics in a steep, boulder-rich mountain stream. We compared two nearly adjacent reaches of third-order Mack Creek over the period 1978–1997 after virtually all wood was removed from the channel of...

In 1980 Creutz [1] displayed quark confinement at moderate coupling in lattice simulations [2] of both abelian and nonabelian gauge theories. Whether nonabelian confinement is as much an artifact of Wilson’s action as is abelian confinement remains unclear. The basic variables of Wilson’s formulation are elements of a compact group and enter the action only through traces of their products. Wil...

Little is known about the ecological significance of tundra fires” (Wein 1976...

www.frontiersinecology.org © The Ecological Society of America M non-native tunicate species have recently invaded the coastal waters of North America and pose serious threats to marine ecosystems (McKindsey et al. 2007). The tunicates occur in such massive numbers that the substratum itself may be entirely obscured (Figure 1). In particular, an invasion by the tunicate Ciona intestinalis (henc...

The dwarf galaxias, Galaxiella pusilla (Mack), is a small, threatened freshwater fish from coastal south-eastern Australia. Recent genetic studies, using multiple nuclear and mitochondrial DNA markers, found substantial differences between populations in western Victoria and south Australia ('west region') compared to eastern Victoria, Flinders Island, and Tasmania ('east region') that suggest ...

one of the subjects which have long been obsessing the minds and spirits of deep-thinking believers is the relationship between religion in all aspects and scopes we can consider for it and the model of reason and rationality. the scope of religious studies is full of various and ever-emerging questions in this regard. there are diverse approaches to the relation between these two. adopting eac...
