Efficient Order and Resource Coordination in Mass Customization
No full textMass customization manufacturing systems require a high level of adaptability and flexibility in production – especially in production planning and control. In particular, the Coordination of orders and resources is critical, because of the high volatility and the make to order principle. Multi-agent systems theoretically provide the required features to handle that complexity, but a lack of informational integration and organizational incompatibilities lead to low applicability. The application of Internet Technology provides the necessary interoperability and organizational alignment to support an overall application of multi-agent systems in mass customization.Mass Customization; Internet Technologies; Multi Agent Systems; Production Planning and Control

Short text authorship attribution via sequence kernels, Markov chains and author unmasking: An investigation
No full textWe present an investigation of recently proposed character and word sequence kernels for the task of authorship attribution based on relatively short texts. Performance is compared with two corresponding probabilistic approaches based on Markov chains. Several configurations of the sequence kernels are studied on a relatively large dataset (50 authors), where each author covered several topics. Utilising Moffat smoothing, the two probabilistic approaches obtain similar performance, which in turn is comparable to that of character sequence kernels and is better than that of word sequence kernels. The results further suggest that when using a realistic setup that takes into account the case of texts which are not written by any hypothesised authors, the amount of training material has more influence on discrimination performance than the amount of test material. Moreover, we show that the recently proposed author unmasking approach is less useful when dealing with short texts

Increased myocardial SERCA expression in early type 2 diabetes mellitus is insulin dependent: In vivo and in vitro data
No full textBackground: Calcium (Ca2+) handling proteins are known to play a pivotal role in the pathophysiology of cardiomyopathy. However little is known about early changes in the diabetic heart and the impact of insulin treatment (Ins). Methods: Zucker Diabetic Fatty rats treated with or without insulin (ZDF +/- Ins, n = 13) and lean littermates (controls, n = 7) were sacrificed at the age of 19 weeks. ZDF + Ins (n = 6) were treated with insulin for the last 6 weeks of life. Gene expression of Ca2+ ATPase in the cardiac sarcoplasmatic reticulum (SERCA2a, further abbreviated as SERCA) and phospholamban (PLB) were determined by northern blotting. Ca2+ transport of the sarcoplasmatic reticulum (SR) was assessed by oxalate-facilitated 45Ca-uptake in left ventricular homogenates. In addition, isolated neonatal cardiomyocytes were stimulated in cell culture with insulin, glucose or triiodthyronine (T3, positive control). mRNA expression of SERCA and PLB were measured by Taqman PCR. Furthermore, effects of insulin treatment on force of contraction and relaxation were evaluated by cardiomyocytes grown in a three-dimensional collagen matrix (engineered heart tissue, EHT) stimulated for 5 days by insulin. By western blot phosphorylations status of Akt was determed and the influence of wortmannin. Results: SERCA levels increased in both ZDF and ZDF + Ins compared to control (control 100 +/- 6.2 vs. ZDF 152 +/- 26.6* vs. ZDF + Ins 212 +/- 18.5*# % of control, *p < 0.05 vs. control, #p < 0.05 vs. ZDF) whereas PLB was significantly decreased in ZDF and ZDF + Ins (control 100 +/- 2.8 vs. ZDF 76.3 +/- 13.5* vs. ZDF + Ins 79.4 +/- 12.9* % of control, *p < 0.05 vs control). The increase in the SERCA/PLB ratio in ZDF and ZDF +/- Ins was accompanied by enhanced Ca2+ uptake to the SR (control 1.58 +/- 0.1 vs. ZDF 1.85 +/- 0.06* vs. ZDF + Ins 2.03 +/- 0.1* mu g/mg/min, *p < 0.05 vs. control). Interestingly, there was a significant correlation between Ca2+ uptake and SERCA2a expression. As shown by in-vitro experiments, the effect of insulin on SERCA2a mRNA expression seemed to have a direct effect on cardiomyocytes. Furthermore, long-term treatment of engineered heart tissue with insulin increased the SERCA/PLB ratio and accelerated relaxation time. Akt was significantly phosphorylated by insulin. This effect could be abolished by wortmannin. Conclusion: The current data demonstrate that early type 2 diabetes is associated with an increase in the SERCA/PLB ratio and that insulin directly stimulates SERCA expression and relaxation velocity. These results underline the important role of insulin and calcium handling proteins in the cardiac adaptation process of type 2 diabetes mellitus contributing to cardiac remodeling and show the important role of PI3-kinase-Akt-SERCA2a signaling cascade

Epigrafía maya: Tabasco
No full textLa información de esta miniguía está basada en los trabajos de M. Coe, N. Grove, S. Guenter, S. Martín, P. Mathews, Linda Schele, D. Stuart y M. U. Zender.Cuatro de las grandes culturas desarrolladas en Mesoamérica poseían un sistema propio de escritura: zapoteca, maya, mixteca y náhuatl. La escritura maya fue el sistema más complejo y el que más correspondencia tuvo con la lengua hablada. Parece haber surgido alrededor del 100 o 200 d.C., y según la mitología fue el dios ltzamná quien la inventó. Sus últimas expresiones se sitúan alrededor de 1696. Los mayas utilizaron diferentes soportes para plasmar la escritura y su historia escrita, como códices de papel vasijas de barro, textiles, pieles, estelas y altares de piedra, dinteles y cajas de madera, pendientes de hueso y hasta finas puntas de cola de mantarraya, entre otros.</p
