Guaiacol appears as a viscous colorless oil, although aged or impure samples are often yellowish. It occurs widely in nature and is a common product of the pyrolysis of wood. == Occurrenc...

from angiosperms. Sugarcane bagasse is one useful source of guaiacol; pyrolysis of the bagasse lignins yields compounds including guaiacol, 4-methylguaiacol and 4-vinylguaiacol. === Chemical intermediate === Guaiacol is a useful precursor for the synthesis of other compounds. Being derived from biomass, it is a potenti...

Replica cluster move in condensed matter physics refers to a family of non-local cluster algorithms used to simulate spin glasses. It is an extension of the Swendsen-Wang algorithm in that it generates non-trivial spin clusters informed by the interaction states on two (or more) replicas instead of just one. It is diff...

Following this, for every grey cluster (blue clusters connected with red bonds), we can rotate all the clock states simultaneously by a random angle. It can be shown that both updates are consistent with the bond-formation rules, and sat...

To efficiently extend this algorithm to higher dimensions, one has to perform certain algorithmic interventions. For instance, one can res...

Theistic evolution (also known as theistic evolutionism or God-guided evolution), alternatively called evolutionary creationism, is a view that God acts and creates through laws of nature. Here, God is taken as the primary cause while natural causes are secondary, positing that the concept of God and religious beliefs ...

Regarding the embracing of Darwinian evolution, historian Ronald Numbers describes the position of the late 19th-century geologist George Frederick Wright as "Christian Darwinism". Jacob Klapwijk and Howard J. Van Till have, while accepting both theistic creation and evolution, rejected the term "theistic evolution". I...
