Photoinitiated polymerization of multifunctional monomers and oligomers is one of the most efficient methods to produce quasi-instantly highly cross-linked polymer networks. It has found a large number of commercial applications, mainly in the coating and printing industry. Among the advantages of this technology the high cure speed, the reduced energy consumption, and the absence of VOC emissi...

In this letter we will dicuss the possibility of a resummation procedure in order to cure the UV/IR-mixing problem of noncommutative field theories. The method is presented for a scalar φ theory on Euclidean space. Finally, we sketch the idea of resummation for U(1)-gauge theories.

Coronavirus disease (COVID-19) has emerged as a major global challenge since 2019. With the fast rise in infected cases and deaths worldwide, many environmental climate-related myths fallacies spreaded fast. These include virus cannot spread hot humid conditions, cold weather can inhibit virus, drinking water sunlight help cure COVID-19, ultraviolet (UV) disinfectant lamps UV rays from kill use...

Xeroderma pigmentosum (XP) is a rare autosomal recessive disease of deoxyribonucleic acid (DNA) repair with ultraviolet (UV) radiation sensitivity and a 10 000-fold increased risk of skin cancer. Symptoms include: freckle-like pigmentation in sun-exposed skin before age 2 years, severe burns after minimal sun exposure (50% of patients) and damage to exposed surfaces of the eyes with loss of vis...
