Evaluating nonlinear HPA models regarding to problem of simulating intermodulation products (IMP). Proposing the polysine model for precise simulation of IMPs, especially for signals with complex structures. Proposing the use of predistortion schemes for MIMO-STBC systems based on thorough analyses of the nonlinear HPA effects on these systems with transmit/receive filters introduced in the model.

For hundreds of years, business people have been transmitting their wisdom generation to generation. In the middle 1990’s companies started to create units focused in managing their knowledge. Nowadays, Knowledge Management is still a relatively new discipline focused in developing the main competitive advantage that organizations have: the intellectual assets. Organizations recognise that Social Media can be enormously used to influence their customers. However, they exactly do not know how to confront this new tool.

Chapter summary: External unshielded twisted pair (UTP) cable installations use prefabricated cables to connect computers directly to hubs; internal cable installations use bulk cable, which you pull through walls, ceilings, or floors; to connect two computers without a hub, you must use a crossover cable connection, which reverses the transmit and receive signals;...

Most (78%) mitochondrial genomes in the studied mutant strain of Drosophila subobscura have undergone a large-scale deletion (5 kb) in the coding region. This mutation is stable, and is transmitted intact to the offspring. This animal model of major rearrangements of mitochondrial genomes can be used to analyse the involvement of the nuclear genome in the production and maintenance of these rearrangements.

Diseases transmitted by hematophagous (blood-feeding) insects are responsible for millions of human deaths world-wide. Inhematophagous insects, thebloodmeal is important for regulating egg maturation. Although a high concentra-tion of iron is toxic for most organisms, hematophagous insects seemunaffectedby the iron load inabloodmeal.One means by which hematophagous insects handle this iron load is, perhaps, by the expression of iron-binding proteins, specifically the iron storage protein ferritin....

The peptide hormone endothelin transmits various signals throughGprotein-coupled receptors, the endothelin type A (ETAR) and B (ETBR) receptors. Caveolae are specialized lipid rafts containing polymerized caveolins. We examined the interaction of ETBR with caveolin-1, expressed in Sf9, COS-1, and HEK293 cells, and its effects on the subcellular distribution and the signal transduction of ETBR.

Nociceptors are specialized nerve fibers that transmit noxious pain stimuli to the dorsal horn of the spinal cord. A subset of nociceptors, the nonpepti-dergic C-fibers, is characterized by its reactivity for the plant isolectin B4 (IB4) from Griffonia simplicifolia. The molecular nature of the IB4-reactive glycoconjugate, although used as a neuroanatomical marker for more than a decade, has remained unknown.

Mastreviridae, of the family geminiviridae, possess a monopartite genome and are transmitted by leafhoppers. Bean yellow dwarf dirus (BeYDV) is a mastrevirus which originated from South Africa and infects dicoyledenous plants, a feature unusual for mastreviridae. Previously, the nonstructural proteins Rep and RepA were examined with respect to their independent roles in BeYDV replication.

The signal of the plant hormone cytokinin is perceived by membrane-located sensor histidine kinases and transduced by other members of the plant two-component system. InArabidopsis thaliana, 28 two-component system proteins (phosphotransmitters and response regulators) act down-stream of three receptors, transmitting the signal from the membrane to the nucleus and modulating the cellular response.

Triatoma infestans(Hemiptera: Reduviidae) is a hematophagous insect that transmits the protozoan parasite Trypanosoma cruzi, the etiological agent of Chagas’ disease. Its saliva contains trialysin, a protein that forms pores in membranes. Peptides based on the N-terminus of trialysin lyse cells and fold into a-helical amphipathic segments resembling antimicrobial peptides. Using a specific antiserum against trialysin, we show here that trialysin is synthesized as a precursor that is less active than the protein released after saliva secretion. ...

Despite the critical importance of protein ubiquitination in the regulation of diverse cellular processes, the molecular mechanisms by which cells rec-ognize and transmit ubiquitin signals remain poorly understood. The endosomal sorting machinery component hepatocyte growth factor-regu-lated tyrosine kinase substrate (Hrs) contains a ubiquitin-interacting motif (UIM), which is believed to bind ubiquitinated membrane cargo proteins and mediate their sorting to the lysosomal degradation pathway.

Amongst a wide variety of different biochemical reactions in cellular car-bon metabolism, thiamin diphosphate-dependent enzymes catalyze the oxi-dative decarboxylation of 2-keto acids. This type of reaction typically involves redox coupled acyl transfer to CoA or phosphate and is mediated by additional cofactors, such as flavins, iron-sulfur clusters or lipoamide swinging arms, which transmit the reducing equivalents that arise during keto acid oxidation to a final electron acceptor.
