- th / 9902097 INFLATING , WARMING UP , AND PROBING THE PRE - BANGIAN UNIVERSE
نویسنده
چکیده
Classical and quantum gravitational instabilities, can, respectively, inflate and warm up a primordial Universe satisfying a superstring-motivated principle of " Asymptotic Past Triviality ". A physically viable big bang is thus generated without invoking either large fine-tunings or a long period of post-big bang inflation. Properties of the pre-bangian Universe can be probed through its observable relics, which include: i) a (possibly observable) stochastic gravitational-wave background; ii) a (possible) new mechanism for seeding the galactic magnetic fields; iii) a (possible) new source of large-scale structure and CMB anisotropy.

The cosmic microwave background radiation (CMBR) we observe today provides a window to an early stage in our universe’s evolution, when the expanding universe had cooled to the point that free electrons and ionized nuclei recombined to form atoms. Before recombination, scattering between photons and free electrons was frequent, and the distance that light could penetrate was small; afterward, w...

The measurements of CMB anisotropy have opened up a window for probing the global topol-ogy of the universe on length scales comparable to and beyond the Hubble radius. We have developed a new method for calculating the CMB anisotropy in models with nontrivial topol-ogy and apply it to open universe models with compact spatial topology. We conduct a Bayesian probability analysis for a selection...

متن کاملHigh Order Masking of Look-up Tables with Common Shares
Masking is an effective countermeasure against side-channel attacks. In this paper, we improve the efficiency of the high-order masking of look-up tables countermeasure introduced at Eurocrypt 2014, based on a combination of three techniques, and still with a proof of security in the Ishai-Sahai-Wagner (ISW) probing model. The first technique consists in proving security under the stronger t-SN...

Introduction & Objective: Nasolacrimal duct obstruction (NLDO) is the most common cause of epiphora in adults. Our purpose was the evaluation of efficacy and complications of NLD probing with adjunctive MMC in the treatment of partial NLDO in adults. Materials & methods: This clinical trial study without control group (quazi experimental) was carried out in adult patients with symptom of epi...
