“…A somewhat similar phenomenon has been discussed by McDonald [29], who showed using a linear analysis that the self-interaction of the inflaton field may lead to the formation of "condensate lumps". In our case, the interaction with the matter field χ plays a more important role, because the inflaton-matter coupling is stronger than the inflaton self-coupling and because the instability at the end of inflation generates large inhomogeneities in the χ field.…”

“…It is, nevertheless, interesting to speculate whether they could have significant cosmological consequences, because the local energy density inside them is much higher than the reheat temperature. In more complicated models in which the inflaton ϕ is charged under a continuous global symmetry, the hot spots may, in fact, become stable Q-balls [29,30].…”

We study the instability of a scalar field at the end of hybrid inflation, using both analytical techniques and numerical simulations. We improve previous studies by taking the inflaton field fully into account, and show that the range of unstable modes depends sensitively on the velocity of the inflaton field, and thereby on the Hubble rate, at the end of inflation. If topological defects are formed, their number density is determined by the shortest unstable wavelength. Finally, we show that the oscillations of the inflaton field amplify the inhomogeneities in the energy density, leading to local symmetry restoration and faster thermalization. We believe this explains why tachyonic preheating is so effective in transferring energy away from the inflaton zero mode.Comment: 12 pages, 10 figures, REVTeX. Minor changes, some references added.

“…Glucose solutions are most stable at around pH 4. 38 Collectively, protein dissolution and remaining reducing sugars might be maximized under an extraction pH at 4, this could explain why CMP-4 had the highest content of protein and reducing sugars. When dissolved in distilled water, CMP-2, CMP-4, and CP presented an acidic pH, while CMP-6 and CMP-8 presented a neutral pH.…”

A new approach to extract pectin from clementine peel using citric acid/sodium citrate solutions (CSS) at different pHs as green extracting agents was proposed. In this study, the effects of extraction temperature (65–85 °C), CSS pH (2–8), and extraction time (1–3 h) on the extraction yield, uronic acid content, and degree of methyl esterification (DE) of the clementine peel pectin (CMP) were systematically evaluated by response surface methodology (RSM). Compared with traditional methods, the CMP extracted by this new approach was of higher pectin yield (19.90–34.94%) and uronic acid content (44.96–65.11%), as well as a wide DE value (11.05–84.71%). These functional properties of CMP were mainly determined by the CSS pH and extraction temperature. In comparison with commercial citrus pectin (CP), the extracted CMPs showed lower protein contents and larger molecular weights. The analysis of monosaccharide compositions showed that the high- and low-methyl-esterified CMPs were dominated by homogalacturonans and rhamnogalacturonan-I, respectively. The structural differences between high- and low-methyl-esterified CMPs were identified by their FTIR spectra. Especially, an excellent gel-forming capacity was found in low-methyl-esterified CMP solutions since their rheological behaviors were highly sensitive to low pH and the presence of Ca2+.

“…The right-handed sneutrino can develop a large field value during inflation, and after the inflation ends it begins to oscillate coherently, which can induce a large abundance of the right-handed sneutrino [58,59]. Its energy density-toentropy ratio ρν R /s is fixed at the end of the reheating process,…”

We present models of decaying particles to increase the effective number of neutrinos N ν after big bang nucleosynthesis but before the structure formation begins. We point out that our scenario not only solves the discrepancy between the constraints on N ν from these two epochs, but also provides a possible answer to deeper inconsistency in the estimation of the matter power spectrum amplitude at small scales, represented by σ 8 , between the WMAP and some small scale matter power measurements such as the Lyman-α forest and weak lensing. We consider (a) saxion decay into two axions; (b) gravitino decay into axino and axion; (c) Dirac right-handed sneutrino decay into gravitino and right-handed neutrino.
