Why the other line[s] is likely to move faster and psychology.

Bill Hammack explains in simple terms how your line (queue) is likely to be slower compare to others [video] with mentioning Erlang's work. An interesting point in his explanation is that how humans perseive multi-queue over single queue with multiple-servers, namely assumption of multi-queue is necessarily better. Similar misconception appears in the airline boarding rules. It is very interesting that we think that multiple queues would help in row-based boarding on the airline, which is not. Recent work by Israeli group shows that random boarding is superior [doi].

Quantum Monte Carlo: Fast force computation

A recent article [doi] by Italian group proposes usage of algorithmic differentiation for force computations appeared in Quantum Monte Carlo technique.

Charge density identification in ion channels

Israeli group has published a recent article [doi] on the identification of charges in ion channels via PNP formalism ( which I have also reviewed shortly [pdf] ).

Cooperation and punishment via game theory in adversarial societies

A recent work discusses the role of cooperation and punishment from game theoretic perspective in adversarial societies [link]. A counter-intuitive finding is that defectors may lead to a peaceful society by introducing a player -informant- with no clear strategy.
