"Pathology and Genetics of Tumours of Soft Tissue and Bone" is the fifth volume in the new WHO series on histological and genetic typing of human tumours. It covers tumours of soft tissue and bone including inherited tumour syndromes. Each entity is extensively discussed with information on clinicopathological, epidemiological, immunophenotypic and genetic aspects of these diseases. Diagnostic cr

In this paper, we present a method of constructing new families of LDPC block code ensembles formed by terminating irregular protograph-based LDPC convolutional codes. Using the accumulate-repeat-by-4-jagged-accumulate (AR4JA) protograph as an example, a density evolution analysis for the binary erasure channel shows that this flexible design technique gives rise to a large selection of LDPC block

We present a decomposition approach to a class of social welfare optimization problems for optimal power flow in multi-region electricity networks. The electricity network is decomposed into multiple regions which decide independently over the amount of power produced within the region and exchanged with neighboring regions. We decompose the overall power flow (or social welfare) optimization into

Given an input consisting of an n-vertex convex polygon with k hole vertices or an n-vertex planar straight line graph (PSLG) with k holes and/or reflex vertices inside the convex hull, the parameterized minimum number convex partition (MNCP) problem asks for a partition into a minimum number of convex pieces. We give a fixed-parameter tractable algorithm for this problem that runs in the followin

Kuhns betydelse för vetenskapsteorin beskrivs kortfattat, från introduktionen av idén om paradigmskiften till hans senare utarbetade uppfattning om vetenskapen som en evolutionär process och skilda vetenskapliga språk som inkommensurabla. Hans inflytande på teologin, särskilt diskussionen om naturvetenskap och teologi, tecknas.

What is the significance of a place at the seashore? What kind of a sense of place does a place by the seashore constitute in the absence of any kind of monumental structures? Today, it is obvious within the archaeological domain that archaeological material culture is not only functional, but also acts as a metaphor for people’s self-perception. In this article, my assumption is that the differen

UHT direct steam injection and steam infusion are widely used; however there is no comparison of their impact on milk components. This study evaluates the structural changes at different steps during the UHT processing of whole milk in a full-scale UHT plant by transmission electron microscopy (TEM) and particle size measurements, and follows the enzymatic activity. The results of structural anal

To be able to improve the quality of dairy products and dairy processes, knowledge of casein molecules, casein micelles and casein aggregates is important. The rheological properties of casein products, casein gels and adsorbed layers of casein, have been widely investigated. However, the micellar properties of casein could, until recently, only be studied by ensemble methods such as dynamic light

Vid den nordiska konferensen ”Teaching bioethics” illustrerade transplantationskirurgen Nils H. Persson och jag hur en dialogpedagogisk metod kan belysa en frågeställning på ett sätt som är svårt för en ensam lärare. Nils H. Persson diskuterade bland annat den stora skillnaden i frekvens av organdonationer mellan de nordiska länderna, mindre än 15 PMP (per million population), och Spanien, mer än
