Lichenized fungi synthesize a great variety of secondary metabolites. These are typically crystalline compounds, which are deposited extracellularly on the fungal hyphae. While we know a lot about the chemical properties and structures of these substances, we have very little information on the molecular background of their biosynthesis. In the current study we analyze the diversity of non-redu...

The Guaymas Basin (Gulf of California) is a hydrothermal vent site where thermal alteration of deposited planktonic and terrestrial organic matter forms petroliferous material which supports diverse sulfate-reducing bacteria. We explored the phylogenetic and functional diversity of the sulfate-reducing bacteria by characterizing PCR-amplified dissimilatory sulfite reductase (dsrAB) and 16S rRNA...

Initiation, Response, and Feedback(IRF) sequences are the most frequent interaction network in any classroom contexts. IRF sequences have been examined profusely in previous studies and were reported to be negatively correlated with participation opportunities (Kasper, 2006; Cazden, 2001; Ellis, 1994).In all these studies, all contingent factors of any classroom context which might influence in...

In this paper, we report two subsets of partitioning strategies utilised by a sample of twelve Grade 3 children when they were asked to solve sequences of partitioning problems. These strategies emerged when the children sought to make the process o.fpartitioning more efficient in terms of generating equal shares, reducing the number of steps involved in partitioning and reducing the load on wo...

In many applications, the data of interest comprises multiple sequences that evolve over time. Examples include currency exchange rates, network traffic data. We develop a fast method to analyze such co-evolving time sequences jointly to allow (a) estimation/forecasting of missing/delayed/future values, (b) quantitative data mining,and (c) outlier detection. Our method, MUSCLES, adapts to chang...

Desulfitobacterium hafniense strain DH is a sulfate-reducing species. Here, we report the draft genome sequence of strain DH, with a size of 5,368,588 bp, average G+C content of 47.48%, and 5,296 predicted protein-coding sequences.

By introducing all zero block (AZB) algorithm, this paper provides an easily implement solution for reducing the complexity of an 8x8 integer transform and quantization. Through the statistic analysis of all zero block for more than 30 typical sequences, We set cubic modules for threshold decision of QCIF, CIF and 720p which can almost reach 100% accuracy and averagely save 5%~40% (according to...

A methodology for the synthesis of communication protocols based on evolutionary techniques is presented. It enables to automatically generate finite-state models that synthesize protocol specifications from partial input/output sequences. These partial sequences, directly derived from service specifications and a set of associated protocol data units (PDUs), are the training sequences that dri...
