First passages in bounded domains: When is the mean first passage time meaningful?

We study the first passage statistics to adsorbing boundaries of a Brownian motion in bounded two-dimensional domains of different shapes and configurations of the adsorbing and reflecting boundaries. From extensive numerical analysis we obtain the probability P(ω) distribution of the random variable ω=τ1/(τ1+τ2), which is a measure for how similar the first passage times τ1 and τ2 are of two independent realizations of a Brownian walk starting at the same location. We construct a chart for each domain, determining whether P(ω) represents a unimodal, bell-shaped form, or a bimodal, M-shaped behavior. While in the former case the mean first passage time (MFPT) is a valid characteristic of the first passage behavior, in the latter case it is an insufficient measure for the process. Strikingly we find a distinct turnover between the two modes of P(ω), characteristic for the domain shape and the respective location of absorbing and reflective boundaries. Our results demonstrate that large fluctuations of the first passage times may occur frequently in two-dimensional domains, rendering quite vague the general use of the MFPT as a robust measure of the actual behavior even in bounded domains, in which all moments of the first passage distribution exist.

On a meaningful integration of web services in data-intensive biomedical environments: The DICODE approach

This paper reports on an innovative approach that aims to reduce information management costs in data-intensive and cognitively-complex biomedical environments. Recognizing the importance of prominent high-performance computing paradigms and large data processing technologies as well as collaboration support systems to remedy data-intensive issues, it adopts a hybrid approach by building on the synergy of these technologies. The proposed approach provides innovative Web-based workbenches that integrate and orchestrate a set of interoperable services that reduce the data-intensiveness and complexity overload at critical decision points to a manageable level, thus permitting stakeholders to be more productive and concentrate on creative activities.

Ukraine: Can meaningful reform come out of conflict? Bruegel Policy Contribution 2014/08, August 2014

Apart from threats to its national security and territorial integrity, Ukraine faces serious economic challenges. These result from the slow pace of economic and institutional reform in the previous two decades, the populist policies of the Yanukovych era and the consequences of the conflict with Russia. The new Ukrainian authorities have made pro-reform declarations, but these do not seem to be supported sufficiently by concrete policy measures, especially in the critical areas of fiscal, balance-of-payment and structural adjustment. Also, the international financial aid package granted to Ukraine has not been accompanied by sufficiently strong policy conditionality. Ukraine urgently needs a complex programme of far-reaching economic and institutional reform, which will include both short-term fiscal and macroeconomic adjustment measures and medium- to long-term structural and institutional changes. Energy subsidies and the low retirement age are the two critical policy areas that require adjustment to avoid sovereign default and a balance-of-payments crisis.
