We introduce a new approach to the Higgs naturalness problem. The mixes with dilaton of conformal field theory (CFT) sector whose true ground state has large negative vacuum energy. If expectation value is nonzero and below $\mathcal{O}(\mathrm{TeV})$, CFT admits second metastable vacuum, where expansion history Universe conventional. As result, only Hubble patches unnaturally small values mass...

Naturalness is a complex concept and number of parameters might impact naturalness perception. In this work, we addressed how the combination different elevation levels size prints impacts perception 2.5D prints. The results subjective ranking experiment showed that observers perceived as more natural at higher with larger print. Moreover, observed seems to be dominant parameter than print for ...

A bstract We demonstrate that the physics which resolves naturalness problems need not take form of new particles and can sometimes manifest itself as higher dimensional operators. As a proof principle, we present simple model where scale is parametrically separated from estimated via arguments applied to self-quartic couplings. In this example, appear far above $$ m/\sqrt{\lambda } <mml:math x...

Here the “Uncanny Valley”, where falling just short of perfection in creating synthetic humans exacts a large negative reaction, is explored with talking head animations focusing on naturalness in speech, face model and face motion. We discuss possible techniques to manipulate naturalness for each of these aspects. Outcomes of this method will provide insights for the choice of the degree of re...

Unit selection (US) TTSs generate quite natural speech but highly variable in quality. Statistical parametric (SP) systems offer far more consistent quality but reduced naturalness due to its vocoding nature. We present a hybrid approach (HA) that tries to improve the overall naturalness combining both synthesis methods. Contrary to other works, the fusion of methods is performed both in prosod...
