Fluctuations in Inflation and Matching with Experimental Data
Năstase, Horaţiu [UNESP]Made available in DSpace on 2020-12-12T02:07:46Z (GMT). No. of bitstreams: 0 Previous issue date: 2019-01-01; In this chapter we will show how to calculate the spectrum of fluctuations during inflation, and relate that to observables. We will quantize fluctuations during inflation, and show what power spectrum they give, and how that reflects into the CMBR fluctuations. The final point will be how to then const...
Analysis of SIRT1 Expression in Plasma and in an in Vitro Model of Preeclampsia
Viana-Mattioli, Sarah [UNESP]; Nunes, Priscila [UNESP]; Cavalli, Ricardo; Sandrim, Valeria [UNESP]Made available in DSpace on 2020-12-12T02:07:46Z (GMT). No. of bitstreams: 0 Previous issue date: 2020-01-01; Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP); Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq); Preeclampsia (PE) is a pregnancy-specific disorder that affects 3-8% expecting mothers worldwide being one of the main causes of maternal and fetal morbidity and mortality...
Holography and the AdS/CFT Correspondence
Năstase, Horaţiu [UNESP]Made available in DSpace on 2020-12-12T02:07:52Z (GMT). No. of bitstreams: 0 Previous issue date: 2019-01-01; In this chapter, we will describe the AdS/CFT correspondence, which relates a gravity theory, usually in an Anti-de Sitter (AdS) d+ 1 dimensional background to a field theory with conformal invariance (CFT) in d dimensions, living at a boundary of the space. Therefore the correspondence is an example of...
Extra Dimensions and Kaluza–Klein
Năstase, Horaţiu [UNESP]Made available in DSpace on 2020-12-12T02:07:53Z (GMT). No. of bitstreams: 0 Previous issue date: 2019-01-01; In this chapter we will study the idea of extra dimensions, as proposed by Kaluza and Klein. The idea of having extra dimensions, besides our usual 3 + 1, is an old one. Already Theodor Kaluza (in 1921) and Oskar Klein (in 1926) had considered it. The general idea of Klein was to consider that our space...
The Propagation of Light and Measurements of Distance, Luminosity and Mass
Năstase, Horaţiu [UNESP]Made available in DSpace on 2020-12-12T02:07:53Z (GMT). No. of bitstreams: 0 Previous issue date: 2019-01-01; In this chapter I will explain in some detail how measurements are made in astrophysics and cosmology, so that we can gain some faith in the fact that we actually can determine things precisely. I will start describing the propagation of light in a cosmological setting, follow on to say how we can use t...
Fuzzy Dark Matter from String Theory
Năstase, Horaţiu [UNESP]Made available in DSpace on 2020-12-12T02:07:54Z (GMT). No. of bitstreams: 0 Previous issue date: 2019-01-01; In this chapter, we will examine an alternative to the usual Λ CDM model, where the cold dark matter is replaced by a “fuzzy dark matter”, and we will see that it appears more naturally in string theory. In fact, it is based on the axionic models from the previous chapter.; Instituto de Física Teórica U...
Big Bang Nucleosynthesis and Recombination
Năstase, Horaţiu [UNESP]Made available in DSpace on 2020-12-12T02:07:54Z (GMT). No. of bitstreams: 0 Previous issue date: 2019-01-01; In this chapter we will describe Big Bang Nucleosynthesis (BBN), the combination of fundamental protons and neutrons into nuclei, as well as calculate more precisely the temperature of recombination.; Instituto de Física Teórica UNESP; Instituto de Física Teórica UNESP
String Gas and Brane Gas Developments
Năstase, Horaţiu [UNESP]Made available in DSpace on 2020-12-12T02:08:00Z (GMT). No. of bitstreams: 0 Previous issue date: 2019-01-01; In this chapter we will first describe a simple generalization of the previously defined string gas cosmology, namely brane gas; and then we will calculate the spectrum of scalar and tensor perturbations in string gas cosmology.; Instituto de Física Teórica UNESP; Instituto de Física Teórica UNESP

The Cyclic and New Ekpyrotic Scenarios
Năstase, Horaţiu [UNESP]Made available in DSpace on 2020-12-12T02:08:00Z (GMT). No. of bitstreams: 0 Previous issue date: 2019-01-01; In this chapter we will study variants of the original ekpyrotic scenario, which are introduced in order to solve some problems with the original model. These are the cyclic model of Steinhardt and Turok, and the new ekpyrotic model of Buchbinder, Khoury and Ovrut.; Instituto de Física Teórica UNESP; In...
