Protein sequence alignmentmay be viewed as either a classification or amultiple hypothesis testing problem.Whereas the type one error of a method is often studied for randomly generated sequences, the power is best investigated based on real protein sequences. The SCOP data base and its protein classification is used to investigate both the power and the type one error of sequence alignment as ...

The SUPERFAMILY hidden Markov model library representing all proteins of known structure predicts the domain architecture of protein sequences and classifies them at the SCOP superfamily level. This analysis has been carried out on all completely sequenced genomes. The ways in which the database can be useful to crystallographers is discussed, in particular with a view to high-throughput struct...

Coarse-grained network models of proteins successfully predict equilibrium properties related to collective modes of motion. In this study, the network construction strategies and their systematic application to proteins are used to explain the role of network models in defining the collective properties of the system. The analysis is based on the radial distribution function, a newly defined a...

If examinees were to know, beforehand, part of the content of a computerized adaptive test, their estimated trait levels would then have a marked positive bias. One of the strategies to avoid this consists of dividing a large item bank into several sub-banks and rotating the sub-bank employed (Ariel, Veldkamp & van der Linden, 2004). This strategy permits substantial improvements in exposure co...

Effects of 6 substances of 29 specifically expressed in the pre-simbiotic phase of Tuber borchii − Tilia americana interaction and root extracts obtained in water and ethanol were tested on T. borchii mycelium. Root extracts increased hyphal branching; this is in agree with data obtained using only endo-mycorhhizal fungi. The tested substances showed various effects on morphology and features o...

Günümüzde ağaç malzemenin yapısal veya yarı alanlarda en ekonomik bir şekilde kullanılması kaçınılmaz zorunluluk haline gelmiştir. Ağaç malzemenin; farklı amaçlarda kullanılması, çeşitli deney yöntemleriyle fiziksel ve mekanik özelliklerinin araştırılarak ortaya konulması ile orantılıdır. Bu amaç doğrultusunda ıhlamur (Tilia tomentosa) odununun; radyal, teğet enine yüzeyde statik sertlik değeri...

321 honey samples from Switzerland were collected. The botanical authenticity of 176 honey samples was confirmed by the determination of electrical conductivity, sugar composition, pH-value, free acidity, and microscopical pollen analysis [2], as well as the sensory evaluation by three experts. The honey samples were assigned to one of the following groups: floral honeys from acacia (Robinia sp...
