Transplantation is the preferred treatment for the most serious forms of kidney disease; deceaseddonor and live-donor kidneys are the two sources for transplantation, and these sources are utilized via two different programs. One of these programs, a two-way kidney paired donation (KPD), involves two patient-donor couples, for each of whom transplantation from donor to intended recipient is not...

The existence of two independent components of long-term memory has been demonstrated by the authors. The evidence has been derived from the authors' findings related to the optimum spacing of repetitions in paired-associate learning. The two components are sufficient to explain the optimum spacing of repetitions as well as the spacing effect. Although the molecular counterparts of the two comp...

The interlimb coordination during overground locomotion was analysed in intact rats, using the method of contact electrodes (Górska et al. 1998). It was found that in animals moving with a speed ranging from 10 to 78 cm/s (step cycles 685 to 215 ms, respectively) the interlimb coordination was characterized by homologous phase shifts close to 0.5 and much shorter diagonal than lateral phase shi...

bones of the pectoral girdle skeleton in representatives of 48 genera in 41 families of eurypterygian fishes were studied. the structure and position of the pectoral girdle is relatively stable in eurypterygians. it consists of the extrascapula, posttemporal, supracleithrum, cleithrum, postcleithrum, scapula, coracoid, actinosts, and fin rays. an ectocoracoid is present in some gasterosteiforme...

Ordovician limestone-marl alternations in the Oslo-Asker District have been interpreted as signaling glacio-eustatic lowstands, which would support a prolonged "Early Palaeozoic Icehouse". However, these rhythmites could alternatively reflect differential diagenesis, without sedimentary trigger. Here, we test both hypotheses through one Darriwilian and three Katian sections. Our methodology con...

BACKGROUND A hierarchy, characterized by tree-like relationships, is a natural method of organizing data in various domains. When considering an unsupervised machine learning routine, such as clustering, a bottom-up hierarchical (BU, agglomerative) algorithm is used as a default and is often the only method applied. METHODOLOGY/PRINCIPAL FINDINGS We show that hierarchical clustering that invo...
