Evaluation of Query Generators for Entity Search Engines [PDF]

arXiv, 2010
Dynamic web applications such as mashups need efficient access to web data that is only accessible via entity search engines (e.g. product or publication search engines). However, most current mashup systems and applications only support simple keyword searches for retrieving data from search engines.

Colossal Terahertz Emission with Ultrafast Tunability Based on Van der Waals Ferroelectric NbOI2

Advanced Optical Materials, EarlyView.
The widespread THz applications are hindered by the scarcity of efficient ultrafast THz sources with on‐demand fast modulation and easy on‐chip integration capability. Here the discovery of colossal THz emission is reported from a van der Waals (vdW) ferroelectric semiconductor NbOI2 and demonstrates the ultrafast coherent control of the THz emission ...

Altered Brain‐Behavior Association During Resting State is a Potential Psychosis Risk Marker

Advanced Science, EarlyView.
The study detects a potential multimodal biomarker that can be promising for identifying early markers of psychosis. It shows a consistent brain‐behavior association between a circuit of interconnected regions and executive function in neurotypical controls and individuals at various stages of psychosis.
