Are analysts' loss functions asymmetric? [PDF]

open access: yes, 2012
Despite displaying a statistically significant optimism bias, analysts' earnings forecasts are an important input to investors’ valuation models. Understanding the possible reasons for any bias is important if information is to be extracted from earnings

Are analysts' loss functions asymmetric? [PDF]

open access: yes, 2005
Recent research by Gu and Wu (2003) and Basu and Markov (2004) suggests that the well-known optimism bias in analysts’ earnings forecasts is attributable to analysts minimizing symmetric, linear loss functions when the distribution of forecast errors is ...

A one-pot, enantioselective allylic oxidation of cycloolefins: a novel benzoic acid/TBHP system catalyzed by Cu-complexed SBA-15-immobilized chiral aniline oxazoline ligands [PDF]

open access: yesRSC Advances
An innovative one-pot approach for efficient enantioselective allylic oxidation of cycloolefins has been developed using benzoic acid derivatives/tert-butyl hydroperoxide to synthesize enantioenriched allylic esters in good to high yields (up to 87%) and

Asymmetric preheating [PDF]

open access: yesInternational Journal of Modern Physics A, 2018
We study the generation of the matter–antimatter asymmetry during bosonic preheating, focusing on the sources of the asymmetry. If the asymmetry appears in the multiplication factor of the resonant particle production, the matter–antimatter ratio will grow during preheating.

In Vivo Nanodetoxication for Acute Uranium Exposure

open access: yesMolecules, 2015
Accidental exposure to uranium is a matter of concern, as U(VI) is nephrotoxic in both human and animal models, and its toxicity is associated to chemical toxicity instead of radioactivity. We synthesized different PAMAM G4 and G5 derivatives in order to

Removal of 4-Ethylphenol and 4-Ethylguaiacol with Polyaniline-Based Compounds in Wine-Like Model Solutions and Red Wine

open access: yesMolecules, 2015
Volatile phenols, such as 4-ethyphenol (4-EP) and 4-ethylguaiacol (4-EG), are responsible for the “Brett character” found in wines contaminated with Brettanomyces yeast (i.e., barnyard, animal, spicy and smoky aromas).
