Title: Innovative Modeling of Cascading Failures in Global Financial Networks
Summary: Stability of the banking system and macro-prudential regulation are essential for healthy economic growth. Bank networks are not isolated by national boundaries, but are rather global either through ownership or operations. Interconnectivity among banks contributes to increased vulnerability of the entire financial institution network. It is importance to understand the financial system susceptibility to distress, because of high level of leverage, interconnectivity of system's entities, similar risk exposure of financial institutions, and possibility of systemic crisis propagation through the network. Current bank stress tests, conducted by central banks, do not take in consideration the connectivity of the banks and the potential for a one bank’s financial risk spilling over to the rest of the system. To address this, we create a bipartite network model for cascading bank failures with bank nodes on one side and asset nodes on the other with weighted links between the two layers. We propose a model for systemic risk propagation based on common bank exposures to specific asset classes. After stressing the bank network, we find that while the system is able to withstand shocks for a wide range of parameters, we identify a critical threshold for asset risk beyond which the system transitions from stable to unstable. We also identify asset classes that increase bank vulnerabilities under given stress scenarios.

Title: Superintelligence and future of human civilization
Summary: The lecture will analyze the prospects of superintelligence and the transformation of the human civilization along the way. The study and predictions are based on basic information laws such as Moore's law that will likely pertain their properties for decades. Besides the positive aspects also some potential dangers are highlighted in order to enable avoiding them.

Title: Video Pandemics: Worldwide Viral Spreading of Psy’s Gangnam Style Video
Summary: Viral videos can reach global penetration traveling through international channels of communication similarly to real diseases starting from a well-localized source. In past centuries, disease fronts propagated in a concentric spatial fashion from the the source of the outbreak via the short range human contact network. The emergence of long-distance air-travel changed these ancient patterns. However, recently, Brockmann and Helbing have shown that concentric propagation waves can be reinstated if propagation time and distance is measured in the flight-time and travel volume weighted underlying air-travel network. Here, we adopt this method for the analysis of viral meme propagation in Twitter messages, and define a similar weighted network distance in the communication network connecting countries and states of the World. We recover a wave-like behavior on average and assess the randomizing effect of non-locality of spreading. We show that similar result can be recovered from Google Trends data as well.
