Uncovering missing links in collegial learning conversations

Uncovering missing links with cold ends

To evaluate the performance of prediction of missing links, the known data are randomly divided into two parts, the training set and the probe set. We argue that this straightforward and standard method may lead to terrible bias, since in real biological and information networks, missing links are more likely to be links connecting low-degree nodes. We therefore study how to uncover missing lin...

Collegial conversations with a Balinese doctor.

A sublime and serendipitous setting I chose the gracious rural village of Penestan in central Bali as a retreat for the beginning of our family journey. Penestan is a sublime setting of tropical ridges of palm, papaya, and tamarind trees; rice terraces; and vibrant traditional village life, against the backdrop of distant volcanoes. Penestan is the cultural home of Balinese painters and dancers...

Yes We Can: Uncovering Spoken Phrases in Encrypted VoIP Conversations

The growing importance of VoIP telephony over untrusted networks raises the requirements to encrypt VoIP calls. To achieve a good trade-off between audio quality and network traffic, Variable Bit Rate (VBR) codecs are widely employed. VBR codecs encode speech data at different bit rates depending on the complexity of the input signal. We implemented a practical side channel attack on VoIP appli...

Cytoskeleton: Missing links found?

The quest for the function of BPAG1, a major hemidesmosomal protein of skin keratinocytes, has led to the discovery of a group of protein isoforms derived from the same genomic locus that are involved in organizing and integrating cytoskeletal networks in sensory neurons.
