at a superficial level it seems that owning a monopolistic right is in contrast with competitiveness of the market, and exercising this right will prevent the free trade from being competitive. but the truth is that the existence of monopoly is not always a violation of competition law to be harmful to the trade, quite the reverse, in some cases it interacts with principles of competition law, ...

The optimal checkpointing algorithm (Griewank and Walther, 2000) minimizes the computational complexity of the adjoint state method. Applied to reverse time migration, optimal checkpointing eliminates (or at least drastically reduces) the need for disk i/o, which is quite extensive in more straightforward implementations. This paper describes optimal checkpointing in a form which applies both t...

Retrieval of a subset of studied items and the presentation of those items as retrieval cues typically impair retrieval of the other items. Previous research on this self-limiting property of memory retrieval has relied heavily on short retention intervals and similar context between encoding and test. Here, we examined retrieval dynamics also after a prolonged retention interval with different...

The introductory chapter, written by Werner Eichhorst and Paul Marx, opens with a generally accepted proposition that European labour markets are undergoing a process of deep transformation characterised by deindustrialization and the growth of non-standard work. This premise is further supported and elaborated through specific insights which establish the general framework for this book. For i...

SIR,-Your leading article (30 January, p. 247) on "New-style Cold Abscesses" is valuable in drawing attention to two recent papers in the British Youmal of Surgery12 which describe a clinical manifestation of tuberculosis relatively much more common in the immigrant section of our population. These subcutaneous cold abscesuses, which are quite often multiple, are a form of tuberculous disease w...
