I will speak about a number of open problems in queueing. Some of them are known for decades, some are more recent. They relate to stability and to rare events. There is an idea to prepare a special issue of QUESTA on open problems, and this text may be considered as a prospective contribution to that. The choice of open problems reflects the speaker’s own interests, and should not be taken as ...

Congenital chloride diarrhoea is a rare disorder mainly reported in Finland. A Malay child with congenital chloride diarrhoea presenting at six months of age with watery stools from birth and failure to thrive is reported.

Effects of disorder are examined in itinerant systems close to quantum critical points. We argue that spin fluctuations due to the long-range part of the RKKY interactions generically induce non-Ohmic dissipation due to rare disorder configurations. This dissipative mechanism is found to destabilize quantum Griffiths phase behavior in itinerant systems with arbitrary symmetry of the order param...

The dental surgeon can feel inadequate when confronted with a rare disease: (a) difficult diagnosis, (b) therapeutic complexity, (c) and questioning by the parents, are three major obstacles that we have to overcome in order to carry out our therapy. Even if the field of genetics has made major advances during the last few years, it is clinical knowledge, above all, that leads us to a diagnosis...

Most writers on the subject claim that chronic intussusception is rare in childhood. Thus Still (1921) stated that in children it occurs 'rarely indeed'; Monrad (1927) wrote: 'Chronic invaginations in my experience are extremely rare in small children'; Beaven (1929) noted that 'judging from the number of cases reported, chronic intussusception is an extremely rare disease in children'; and Nyb...

TB is a rare disease in many high-income countries, which leads to pressures for the pooling of expertise to larger centres [2]. This results in patients being treated in TB centres with higher case loads but greater distances for patients to travel. This study demonstrates that such merging has positive health benefits, as larger centres (load .26 cases?yr) had significantly higher completion ...

Two years ago, at the ECRD in Krakow, we were celebrating the recommendation of the Council of Ministers on an action in the field of rare diseases: this recommendation requests that Member States define and implement a plan or a strategy for rare diseases by the end of 2013 and asks the European Commission to establish a EU Committee of Experts in the field of Rare Diseases (EUCERD) as a forum...

Rare tumors, when considered as a group, represent a significant burden to society as they may account for up to 25% of the mortality by cancer in nations like the United States. In contrast with the current scenario in highly incident cancer types, little progress has been achieved in the treatment of the most rare cancers. The reasons for this apparent stagnation are mostly intrinsic to logis...

What a Difference a Y Makes: Female and Male Nascent Entrepreneurs in Germany In western industrialized countries men are on average more than twice as active in entrepreneurship as women. Based on data from a recent representative survey of the adult population in Germany this paper uses an empirical model for the decision to become selfemployed to test for differences between women and men in...
