HexaLab.net: an online viewer for hexahedral meshes
Get PDFWe introduce HexaLab: a WebGL application for real time visualization,
exploration and assessment of hexahedral meshes. HexaLab can be used by simply
opening www.hexalab.net. Our visualization tool targets both users and
scholars. Practitioners who employ hexmeshes for Finite Element Analysis, can
readily check mesh quality and assess its usability for simulation. Researchers
involved in mesh generation may use HexaLab to perform a detailed analysis of
the mesh structure, isolating weak points and testing new solutions to improve
on the state of the art and generate high quality images. To this end, we
support a wide variety of visualization and volume inspection tools. Our system
offers also immediate access to a repository containing all the publicly
available meshes produced with the most recent techniques for hexmesh
generation. We believe HexaLab, providing a common tool for visualizing,
assessing and distributing results, will push forward the recent strive for
replicability in our scientific community
Stress misconduct and reduced ability to express dissent: A study on a sample of students at the University of Siena
No full textTranscribing: between listening, memory, and invention
Get PDFGiuliano Bracci’s research investigates the process and implications of transcribing a musical work from the past and aims to expand knowledge and understanding of this creative practice. Bracci views the practice of transcribing as a form of listening, as a means of reflecting on the theme of otherness and the relationship between self and other. Following Jacques Derrida’s ideas, he argues that truly respecting a musical work means operating in “absolute ingratitude,” accepting the “always threatening risk of betrayal” and of contaminating the original while, at the same time, being contaminated by it. This approach opens up the invention of new possibilities, in contrast to the musealization and sacralization of works from the past. Integrating contemporary artistic expression with one’s cultural legacy holds the potential to transform one’s relationship with history into a dynamic and creative practice.The thesis narrates a journey in which Bracci progressively sought to create more openings, allowing the selected original musical works to influence, contaminate, and transform his language as a transcriber. Bracci also situates his research within a broader context by engaging with the work and ideas of other composers, performers, musicologists, philosophers, writers, and poets.Bracci’s research offers both theoretical and artistic contributions that may encourage new ways of thinking about transcribing, enriching the discourse on the presence of the past in contemporary music and revealing how transcriptions can enable musical works to be virtually present in contemporary music, reappearing from the past like ghosts.Research in and through artistic practic
Production and characterization of monoclonal antibodies to anti-human chorionic somatomammotropin by immunization with two free synthetic peptides.
No full textThe peptides corresponding to the fragments 135-140 and 166-174 of human chorionic somatomammotropin (hCS) were synthesized, and used to raise monoclonal antibodies to the native hCS molecule. The synthetic peptides were injected into BALB/c mice in the free form, i.e. not conjugated to a carrier, and the spleens were fused with Sp2/01Ag8 myeloma line to produce monoclonal antibodies. The antibodies produced belonged to the IgM and IgG classes and, once purified by affinity chromatography on hCS-Sepharose, they were covalently coupled to macroporous polystyrene beads and characterized by competitive radioimmunoassay. Their affinity constants were determined by elaborating the radioimmunoassay data by nonlinear regression analysis and they were found to range from 10(5) to 10(6) M-1. The evaluation of the affinity constant of the antibodies produced is always important as a measure of the immunogenicity of an antigen, particularly when synthetic peptides are used as immunogens
Boundary regular fixed points in Loewner theory
No full textWe characterize regular fixed points of evolution families in terms of analytical properties of the associated Herglotz vector fields and geometrical properties of the associated Loewner chains. We present several examples showing the rle of the given conditions. Moreover, we study the relations between evolution families and Herglotz vector fields at regular contact points and prove an embedding result for univalent self-maps of the unit disc with a given boundary regular fixed point into an evolution family with prescribed boundary data
Determination of antigen-specific immunoglobulin content in ascitic fluids and antisera
No full textA rapid and sensitive method is described for the determination of the antigen-specific immunoglobulin contents of ascitic fluids and/or antisera. Immunoglobulins are quantitatively separated from the biological fluid by immunoaffinity chromatography on the insolubilized antigen using the Millipore Millititer filtration system to perform the simultaneous assay of multiple samples. The specific immunoglobulins are then eluted at acidic pH and their concentration is estimated by solid-phase competitive radioimmunoassay. Radioimmunoassay values, corrected for dilutions, give the antigen-specific immunoglobulin concentration of ascitic fluids and/or antisera
