In this paper, we report a detailed analysis of the impaired performance of a dysgraphic individual, AD, who produced similar rates of letter-level errors in written spelling, oral spelling, and typing. We found that the distribution of various letter error types displayed a distinct pattern in written spelling on the one hand and in oral spelling and typing on the other. In particular, noncontextual letter substitution errors (i.e., errors in which the erroneous letter that replaces the target letter does not occur elsewhere within the word) were virtually absent in oral spelling and typing and mainly found in written spelling. In contrast, letter deletion errors and multiple-letter errors were typically found in oral spelling and very exceptional in written spelling. Only contextual letter substitution errors (i.e., errors in which the erroneous letter that replaces the target letter is identical to a letter occurring earlier or later in the word) were found in similar proportions in the three tasks. We argue that these contrasting patterns of letter error distribution result from damage to two distinct levels of letter representation and processing within the spelling system, namely, the amodal graphemic representation held in the graphemic buffer and the letter form representation computed by subsequent writing-specific processes. Then, we examined the relationship between error and target in the letter substitution errors produced in written and oral spelling and found evidence that distinct types of letter representation are processed at each of the hypothetized levels of damage: symbolic letter representation at the graphemic level and representation of the component graphic strokes at the letter form processing level.

IL-6-type cytokines play an important role during inflammation and the immune response. In addition, they are involved in haematopoiesis, liver and neuronal regeneration, embryonic development and fertility. We found that IL-6-type cytokine stimulation of cell lines and primary human macrophages results in a different distribution of the DNA-binding competent STAT dimer species in the cytosol and nucleus as demonstrated by electrophoretic mobility shift assays. In the absence of detergent, STAT3/STAT3, STAT1/STAT3 were the predominant species in the cytoplasm while STAT3/STAT3 was predominant in the nucleus. However, in detergent containing total cellular lysates and nuclear fractions prepared with detergent containing buffers, the STAT1/STAT1 homodimer was as prominent or even more prominent than STAT3/STAT3 and STAT1/STAT3. We were interested in the cause of this discrepancy since STAT1-regulated genes have not been described to be expressed upon IL-6-type cytokine stimulation. In addition to the more transient STAT1 activation, IL-6-type cytokines such as IL-6 and OSM lead to a much less efficient STAT1 activation compared to the potent STAT1 activators IFNgamma and IFNalpha. Studies with STAT1-deficient cells revealed that STAT1 activation does not seem to be an important competitive process to STAT3 activation arguing again for a very inefficient STAT1 activation upon IL-6-type cytokine stimulation. We also describe that pY-STAT3 is much more efficiently shuttled into the nucleus than pY-STAT1. [less ▲]

On a generic metric measured space, we introduce a notion of improved concentration of measure that takes into account the parallel enlargement of k distinct sets. We show that the k-th eigenvalues of the metric Laplacian gives exponential improved concentration with k sets. On compact Riemannian manifolds, this allows us to recover estimates on the eigenvalues of the Laplace-Beltrami operator in the spirit of an inequality of Chung, Grigor’yan & Yau, Upper bounds for eigenvalues of the discrete and continuous Laplace operators. Adv. Math. 117(2), 165–178 (1996). [less ▲]

Strain effects on epitaxial thin films of LaNiO3 grown on different single crystalline substrates are studied by Raman scattering and first-principles simulation. New Raman modes, not present in bulk or fully relaxed films, appear under both compressive and tensile strains indicating symmetry reductions. Interestingly, the Raman spectra and the underlying crystal symmetry for tensile and compressively strained films are different. Extensive mapping of LaNiO3 phase stability is addressed by simulations, showing that a variety of crystalline phases are indeed stabilized under strain. The calculated Raman frequencies reproduce the principal features of the experimental spectra, supporting the validity of the multiple strain-driven structural transitions predicted by the simulations.

A digital predistortion (DPD) scheme is presented for non-linear distortion mitigation in multi-carrier satellite communication channels. The proposed DPD has a multiple-input multiple-output architecture similar to data DPD schemes. However, it enhances the mitigation performance of data DPDs using a multi-rate processing algorithm to achieve spectrum broadening of non-linear operators. Compared to single carrier (single-input single-output) signal (waveform) DPD schemes, the proposed DPD has lower digital processing rate reducing the required hardware cost of the predistorter. The proposed DPD outperforms, in total degradation, both data and signal DPD schemes. Further, it performs closest to a channel bound described by an ideally mitigated channel with limited maximum output power. © 2015. The Institution of Engineering and Technology. [less ▲]

Luxembourg is one of the countries with the highest degree of linguistic variety in Europe. The situation of the classroom is challenging as at least three school languages meet children with a multilingual background in their families, very frequently of a different type of repertoire (with more than 50% of the school population having a migrational background). The school system tries to find solutions through the creation of adapted teaching models for newly arrived students and pupils, according to their profile. The research project that we present is based on two pillars: an institutional co-construction between teachers and researchers, with an orientation of mutual empowerment, and an international cooperation between two researchers forming a tandem with more than two wheels because of their experience in teacher education and educational research in various multilingual spaces, not only in Luxembourg, but also in Spain, France, Germany, Russia, the South Pacific, Madagascar and Siberia.
