Shortwave Infrared Light Detection and Ranging Using Silver Telluride Quantum Dots
Advanced Materials, EarlyView.Post‐synthesis surface engineering and doping control significantly improve the performance of Ag₂Te CQD photodiodes, achieving a low dark current of 450 nA cm−2 at −0.5 V, an LDR exceeding 150 dB, and a rapid response speed of ≈25 ns. A proof‐of‐concept LiDAR demonstration in the SWIR using a nanosecond diode laser, achieves decimetre‐level resolution

Measurement and Analysis of an Online Content Voting Network: A Case Study of Digg [PDF]
arXiv, 2009 Emergence of online content voting networks allows users to share and rate content including social news, photos and videos. The basic idea behind online content voting networks is that aggregate user activities (e.g., submitting and rating content) makes high-quality content thrive through the unprecedented scale, high dynamics and divergent quality ...

Co-evolution of Content Popularity and Delivery in Mobile P2P Networks [PDF]
arXiv, 2011 Mobile P2P technology provides a scalable approach to content delivery to a large number of users on their mobile devices. In this work, we study the dissemination of a \emph{single} content (e.g., an item of news, a song or a video clip) among a population of mobile nodes.

Secure Fragmentation for Content-Centric Networks (extended version) [PDF]
arXiv, 2014 Content-Centric Networking (CCN) is a communication paradigm that emphasizes content distribution. Named-Data Networking (NDN) is an instantiation of CCN, a candidate Future Internet Architecture. NDN supports human-readable content naming and router-based content caching which lends itself to efficient, secure, and scalable content distribution ...
