Facile rearrangement of azobenzenes is shown to occur in cases where the azo group is placed in the ortho position to carbonyl electrophiles to furnish the indazole skeleton. While this study demonstrates the illusive nature of o-formylazobenzenes, it offers potential for the synthesis of indazoles and related heterocycles.

Background: Triglyceride-glucose (TyG) index was suggested as a possible surrogate for insulin resistance and a predictor for cardiovascular diseases and diabetes in the non-pregnant population. However, the relationship between TyG index in early pregnancy and adverse pregnancy outcomes (APOs), and the contribution of pre-pregnancy body mass index (BMI) was still illusive.
Methods: A large retrospective cohort study involving 67,936 pregnant Chinese women between 2017 and 2022 was conducted.
Predictive coding accounts of perception state that the brain generates perceptual predictions in the service of processing incoming sensory data. These predictions are hypothesized to be afforded by the brain's ability to internalize useful patterns, that is, statistical regularities, from the environment. We have previously argued that the N300 ERP component serves as an index of the brain's use of representations of (real-world) statistical regularities.

MgBiSb (0 ≤ v ≤ 2) is a class of promising thermoelectric materials that have a high thermoelectric performance around room temperatures, whereas their thermoelectric properties under pressures and temperatures are still illusive. In this study, we examined the influence of pressure, temperature, and carrier concentration on the thermoelectric properties of MgBiSb using first-principle calculations accompanied with Boltzmann transport equations method. There is a decrease in the lattice thermal conductivity of MgSb (i.

Humans have asked themselves the question "who am I" from ancient times. Vedic, upanishadic and buddhist philosophers have pointed out over millennia the illusive nature of the individual self, and posit either a no-self, or a universal Self. Vedantic scholars also posit the illusory nature of the universe (Maya) and suggest that the only reality is the knower (Brahman), a view resonating with modern concepts in quantum theory.

Although the synthesis of chlorophosphazene polymers has been explored for more than 100 years, the shortest yet most illusive monomer, ClP═NH, has never been isolated and fully characterized. Here we investigate the formation of ClP═NH from PCl and NH in chlorobenzene through quantum mechanical calculations. The potential energy surface was mapped using the MP2 Hamiltonian in conjunction with Dunning's correlation-consistent basis sets (aug-cc-pVXZ, where X = D and T).
