This is an investigation in the tradition of Fujita et al (IJCAI 1993), Zhang et al (JSC 1996), Dubois and Dequen (CP 2001) in which CP or SAT techniques are used to answer existence questions concerning small algebras. In this paper, we open the attack on IP loops, an interesting and underinvestigated variety intermediate between loops and groups.

piRNAs are known to silence transposable elements, but not all piRNAs match transposon sequences. Recent studies from Shen et al. (2018) and Zhang et al. (2018) identify rules for piRNA target recognition in Caenorhabditis elegans. Permissive pairing rules allow targeting of essentially all germline mRNAs, while protective mechanisms prevent silencing self-genes.

In the last decade, advances in wireless communication and micro-fabrication have motivated the development of large-scale wireless sensor networks (Akyildiz et al., 2002; Yick et al., 2008). A large number of low-cost sensor nodes, equipped with sensing, computing, and communication units, organize themselves into a multi-hop network. The wireless sensor network takesmeasurements from the envi...

We welcome Zhang et al.’s comment on our recent paper dealing with the significance of the first geochemical and geochronological analyses of deep drill-core samples collected from the basement of the central Tarim basin (Guo et al., 2005). In their comments, Zhang et al. raised three questions with regard to our paper (1) the compatibility of our model with regional geology, (2) our interpreta...

Abrasive wear is defined wear due to hard particles or hard protuberances forced againts and moving along a solid surface. This defination encompasses several different mechanisms by which material removal occoures. The five types of wear are abrasive, adhesive, erosion, fatigue and fretting. The abrasive wear of polymeric materials is the interest and the subject of quite number of literature....

Glycolysis is an essential component of cellular metabolism associated with pluripotent stem cells (PSCs). Two new papers, one by Gu et al. (2016) in this issue of Cell Stem Cell and one by Zhang et al. (2016) in Cell Reports, demonstrate that glycolytic flux is dynamically increased in human primed PSCs upon feeder-free cultivation or conversion into the naive state.

The generation of piRNAs from long primary transcripts requires specialized factors that distinguish these precursors from canonical RNA polymerase II transcripts. Mohn et al. and Zhang et al. provide evidence that in Drosophila melanogaster noncanonical transcription coupled with splicing inhibition differentiates piRNA precursors from mRNAs and ensures their correct processing.
