An efficient and reliable a posteriori error estimate is derived for linear parabolic equations which does not depend on any regularity assumption on the underlying elliptic operator. An adaptive algorithm with variable time-step sizes and space meshes is proposed and studied which, at each time step, delays the mesh coarsening until the final iteration of(More)
Celsr3 and Fzd3, members of "core planar cell polarity" (PCP) genes, were shown previously to control forebrain axon guidance and wiring by acting in axons and/or guidepost cells. Here, we show that Celsr2 acts redundantly with Celsr3, and that their combined mutation mimics that of Fzd3. The phenotypes generated upon inactivation of Fzd3 in different(More)
Nitzschia ZJU1, which originated from the diatom Nitzschia sp. (ash free dry weight of biomass was 0.12 g L−1 and its lipid content was 13.34 %) after 60Co-γ ray irradiation and domestication at high-salinity, was re-mutated by 137Cs-γ irradiation to increase lipid productivity. The lipid yields of the new mutants Nitzschia ZJU2 and Nitzschia ZJU3, which(More)
Diatoms constitute a remarkably diverse and attractive group of microalgae, serving as the main primary producers in many ecosystems and a potential source of renewable biofuel. The enhancement of lipid production in diatoms has been achieved by the optimization of culture conditions, such as temperature, salinity, and nutrient starvation. In this study, we(More)
Chondrus crispus, an economically and medicinally important red alga, is a medicinally active substance and important for anti-tumor research. In this study, 117 C. crispus miRNAs (108 conserved and 9 novel) were identified from 2,416,181 small-RNA reads using high-throughput sequencing and bioinformatics methods. According to the BLAST search against the(More)
Porphyridium purpureum has been utilized in important industrial and pharmaceutical fields. The identification of microRNAs (miRNAs) in this unique species is of great importance: such identification can help fill gaps in the small RNA (sRNA) studies of this organism and help to elucidate essential biological processes and their regulation mechanisms in(More)
A symbiotic alga was successfully isolated from the soil moss Entodon obtusatus found in the Guandi Mountains, Shanxi Province, China, and cultivated under axenic conditions. Morphological observations showed that the symbiotic alga was similar to Chlorococcum Based on phylogenetic analysis of 18S rRNA and rbcL genes and internal transcribed spacer (ITS)(More)
Celsr3 and Fzd3 regulate the development of reciprocal thalamocortical projections independently of their expression in cortical or thalamic neurons. To understand this cell non autonomous mechanism further, we tested whether Celsr3 and Fzd3 could act via Isl1-positive guidepost cells. Isl1-positive cells appear in the forebrain at embryonic day (E)(More)
Two chrysophytes, associated with mosses in Shanxi Province, China, were isolated from Haplocladium strictulum (Card.) Reim, and Timmiella anomala. Both of the Chrysophytes were successfully cultivated under axenic conditions. Morphological observations indicated that the two isolated Chrysophytes belong to the genus Poterioochromonas. However, no loricae(More)
