Silver is considered to be the king among plasmonic materials because it features low inelastic absorption in visible and infrared (vis-IR) spectral regions compared other metals. In contrast, copper commonly regarded as being too lossy for applications. Here, we experimentally demonstrate vis-IR plasmons long nanowires (NWs) with quality factors that exceed a value of 60, determined by spatial...

Attention can be focused voluntarily and effectively on spatial locations in order to enhance the processing of task-relevant events. However, work on 'attentional capture' has demonstrated that spatial biases can be temporarily reset by transient and salient stimuli, especially if they share defining characteristics with the targets of a task goal. In the current study, we investigated whether...

SUSTAIN (Supervised and Unsupervised STratified Adaptive Incremental Network) is a model of how humans learn categories from examples. SUSTAIN initially assumes a simple category structure. If simple solutions prove inadequate and SUSTAIN is confronted with a surprising event (e.g., it is told that a bat is a mammal instead of a bird), SUSTAIN recruits an additional cluster to represent the sur...
