Hydroquinone–pyrrole dyads with varied linkers

A series of pyrroles functionalized in the 3-position with p-dimethoxybenzene via various linkers (CH2, CH2CH2, CH=CH, C≡C) has been synthesized. Their electronic properties have been deduced from (1)H NMR, (13)C NMR, and UV-vis spectra to detect possible interactions between the two aromatic subunits. The extent of conjugation between the subunits is largely controlled by the nature of the lin...

Gradually Varied Surfaces and Gradually Varied Functions

The gradually varied surface was introduced and studied in digital and discrete spaces by Chen. The basic idea of introducing gradually varied surfaces is to employ a purely discrete interpolation algorithm to fit a discrete surface when the desired surface is not required to be “smooth.” In this paper, we generalize the concept of gradually varied surfaces. A digital surface is defined as a ma...

Idiopathic Orofacial Granulomatosis with Varied Clinical Presentation

Orofacial granulomatosis is a granulomatous disease of orofacial region, which can occur for a variety of reasons. The clinical features are highly variable and sometimes so insidious that signs and symptoms are not frequently severe to cause alarm. The lips are most commonly involved with persistent/recurrent swelling. The medical history is very important as Crohn's disease and sarcoidosis ca...

Differential Attachment of Pulmonary Cells on PDMS Substrate with Varied Features

Cancer is now a global concern, and control of the function of cancer cells is recognized as an important challenge. Although many aggressive chemical and radiation methods are in practice to eliminate cancer cells, most imply severe adverse toxic effects on patients. Taking advantage of natural physical differences between cancer and normal cells might benefit the patient with more specific cy...
