- A potential security incident may go unsolved if standardized forensic approaches are not applied during lawfulinvestigations. This paper highlights the importance of mapping the digital forensic application requirementspecification to an international standard, precisely ISO/IEC 27043. The outcome of this work is projected tocontribute to the problem of secure DF tool creation, and in the process address Software Requirements Specification(SRS) as a process of digital evidence admissibility.

- Reproduction in jawed vertebrates (gnathostomes) involves either external or internal fertilization. It is commonly argued that internal fertilization can evolve from external, but not the reverse. Male copulatoryclaspers are present in certain placoderms, fossil jawed vertebrates retrieved as a paraphyletic segment of the gnathostome stem group in recent studies. This suggests that internal fertilization could be primitive for gnathostomes, but such a conclusion depends on demonstrating that copulation was not just a specialized feature of certain placoderm subgroups. The reproductive biology of antiarchs, consistently identified as the least crownward placoderms and thus of great interest in this context, has until now remained unknown. Here we show that certain antiarchs possessed dermal claspers in the males, while females bore paired dermal plates inferred to have facilitated copulation. These structures are not associated with pelvic fins. The clasper morphology resembles that of ptyctodonts, a more crownward placoderm group, suggesting that all placoderm claspers are homologous and that internal fertilization characterized all placoderms. This implies that external fertilization and spawning, which characterize most extant aquatic gnathostomes, must be derived from internal fertilization, even though this transformation has been thought implausible. Alternatively, the substantial morphological evidence for placoderm paraphyly must be rejected.

- The floral assemblage from the Carnian (Upper Triassic) of Lunz-am-See in Austria contains a rich and diverse array of ferns and fern allies, most of which have been considered only marginally, some have been described but more than a century ago and the majority have never been illustrated. Therefore, we here provide a detailed analysis of these taxa accompanied by extensive descriptions, detailed illustrations and colour restorations of the plants. We identified 17 species of lycophytes, sphenophytes and pteridophytes assignable to 14 genera in seven families. One taxon could be identified to class level only. One new genus of dipteridacean ferns (viz. Digitopteris C.Pott et Bomfleur gen. nov.), so far monotypic, is here described from Lunz with its type species Digitopteris repanda C.Pott et Bomfleur sp. nov. The Lunz flora comprises an interesting mixture of eusporangiate Marattiales and leptosporangiate Osmundales, Gleicheniales and Schizaeales; the former representing a rather primitive group of ferns. The co-occurrence of eusporangiate and leptosporangiate ferns renders the Lunz flora important given the fact that eusporangiate ferns were predominating over more modern, leptosporangiate forms during the Paleozoic, whereas they typically constitute only subordinate components in fern vegetation since the mid-Mesozoic until today. Among the leptosporangiate forms, the species from Lunz represent, due to their Triassic age, more primitive forms, which probably were rather growth-restricted thriving as herbaceous understorey layer among the shade of the eusporangiate, tree-like marattialean ferns.

At the frontiers of surgery: review

Forskningsöversikt (refereegranskat)abstract
- The complete surgical removal of disease is a desirable outcome particularly in oncology. Unfortunately much disease is microscopic and difficult to detect causing a liability to recurrence and worsened overall prognosis with attendant costs in terms of morbidity and mortality. It is hoped that by advances in optical diagnostic technology we could better define our surgical margin and so increase the rate of truly negative margins on the one hand and on the other hand to take out only the necessary amount of tissue and leave more unaffected non-diseased areas so preserving function of vital structures. The task has not been easy but progress is being made as exemplified by the presentations at the 2nd Scientific Meeting of the Head and Neck Optical Diagnostics Society (HNODS) in San Francisco in January 2010. We review the salient advances in the field and propose further directions of investigation.
