After a brief introduction (1) this chapter covers: (2) optical tweezers and related techniques, (3) uses of lasers for ablation, desorption, ionization, and dissection, (4) fluorescent labeling, (5) Abbe's diffraction limit to spatial resolution in microscopy, (6) two-photon excitation fluorescence microscopy, (7) stimulated emission depletion (STED), (8) near-field microscopy, (9) quantum dots a
Searches for extra dimensions have been made at the four LEP experiments, ALEPH, DELPHI, L3 and OPAL, where different processes have been searched for within both the ADD and Randall-Sundrum scenarios. Since no signs of any signal have been observed the results have been used to set exclusion limits in the corresponding extra dimension models. This talk presents both individual results from the LE
Abstract in Italian Sono qui messi a confronto due modelli per l’analisi dei Vangeli da un punto di vista retorico: l’utilizzo delle categorie retoriche dei Progymnasmata ellenistici e «la retorica biblica e semitica». Si sostiene che l’utilizzo di un modello non escluda l’utilizzo dell’altro, ma che anzi si completino a vicenda. Un’analisi dell’ultima cena in Lc 22,11-38 serve a illustrare l’uso Two approaches to the rhetorical analysis of Gospel texts are being compared in this essay: on the one hand, the use of the rhetorical categories of the Hellenistic Progymnasmata, and on the other, «Biblical and semitic rhetoric». It is argued that these two approaches are not mutually exclusive, but complementary. The last supper in Luke 22,14-38 functions as a test case. An introduction offers s
The article examines the reception of Old Testament motifs in the so called "Hymn of the Pearl" (preserved in Syriac and Greek as part of the apocryphal Acts of Thomas). Ideas taken up for study include the use of "Egypt" as a symbol of spiritual bondage, the legacy of the West Semitic Chaoskampf motif, the link to Ezekiel 32:2, etc. The main thrust of the article is the transformation of ancient
Resistance to activated protein C (APC) is a major cause of familial thrombophilia, and can be corrected by an anticoagulant activity expressed by purified factor V. We investigated linkage between APC resistance and the factor V gene in a large kindred with familial thrombophilia. Restriction fragment length polymorphisms in exon 13 of the factor V gene were informative in 14 family members. The
Abstract in Spanish El objetivo de este trabajo es reflexionar acerca de las diferentes estrategias de desarrollo que, desde la década de 1990, se vienen construyendo en territorios rurales del norte de Argentina. Para ello, presentamos desde una perspectiva comparativa tres casos de estudio localizados en el noroeste y nordeste del país: la Quebrada de Humahuaca (Jujuy), el departamento de San Ca
This paper explores wartime relationships and the culture of armed groups in the Democratic Republic of Congo (DRC). Without exceptions, the crises in the Congo must be framed in local-global correlations, i.e. in terms of criminal network activities and its linkages to mining businesses and exploitation of natural resources. In the eastern DRC the boundaries between the different armed groups and
The cytosolic Ca2+-binding S100A9 and S100A8 proteins form heterodimers that are primarily expressed in human neutrophils and monocytes. We have recently shown that S100A9 binds to TLR4 in vitro and induces TLR4-dependent NF-κB activation and a pro-inflammatory cytokine response in monocytes. In the present report we have further investigated the S100A9-mediated stimulation of TLR4 in monocytes. U
This paper presents a custom chip for linearization of RF power amplifiers using digital predistortion. The chip has been implemented in a standard digital 0.8 μm CMOS process with standard static cells and single-phase clocking. A systolic complex multiplier based on distributed arithmetic constitutes the core of the chip. The nonlinear function is realized with a look-up table containing complex
This thesis, which is based on four original papers, covers different aspects of antibody development. The overall goal of my work has been to obtain an increased understanding of antibody repertoires as they develop in vivo and in vitro. In Paper I-III antibody repertoires was evaluated and used to dissect virus-induced antibody responses and characterize such antibodies. Furthermore, tools for m
