We use computational models to understand these behaviors by interpreting them mathematically. One component of this analysis is the spatial selectivity or receptive field, a property found in all visual sensory neurons. The neurons found...
Having an emotion involves having an evaluative point of view on one’s circumstances. For example, there is a sense in which being angry involves taking oneself to have been wronged, and fear seems to paint the scene as one of danger. A significant debate in contemporary philosophy of mind concerns...
Our experience of the physical world is mediated by our senses, but while most people have five senses, interactions with computer systems are largely limited to the visual sense. When working with nonvisual artifacts, like sound, on computers, such artifacts are typically transformed, or re-encoded, into something visual. Determining how...

Potassium ions (K+) are one of the most abundant ions in intracellular fluid, affecting a wide variety of cellular processes in living organisms. In humans, irregularities in extracellular K+ levels contribute to pathologies including cardiovascular disease, immunological diseases, and some cancers. Despite the role of K+ ions, the detection, quantification,...
In the English language, wh-question constructions give rise to gap positions in sentences, because the wh-phrase that corresponds with the object of the verb moves to the beginning of the sentence, leaving no word to appear in the typical object position. Typically wh-phrases are associated with just one gap, however,...
Homelessness and menstruation are constructs and processes that are plagued with stigma. For decades, academics have researched menstruation and homelessness as separately stigmatized experiences. However, in the process, scholars have overlooked the converging and intersectional nature of the stigma surrounding homeless menstruation. \\n\\nThrough library research and records, this paper analyzes...
Now more than ever, forecasting the outcomes of U.S. elections is an important and challenging task.
