Instantaneous in vivo distal edge verification in intensity‐modulated proton therapy by means of PET imaging

open access: yesMedical Physics, EarlyView.
Abstract Background Intensity‐modulated proton therapy (IMPT) holds promise for improving outcomes in head‐and‐neck cancer (HNC) patients by enhancing organ‐at‐risk (OAR) sparing. A key challenge in IMPT is ensuring an accurate dose delivery at the distal edge of the tumor, where the steep dose gradients make treatment precision highly sensitive to ...

Aqueous and Non‐Aqueous Synthesis of 2‐(Dimethylamino)ethyl Methacrylate (Co)Polymers by Solution Radical Polymerization: Modeling and Experimental Study

open access: yesMacromolecular Reaction Engineering, EarlyView.
The radical polymerization kinetics of DMAEMA is studied in both aqueous and nonaqueous solution. Solvolysis of the nonionized monomer occurs in aqueous and aqueous‐alcohol systems, leading to the formation of copolymer or terpolymer; this complexity does not arise when DMAEMA is in its ionized form.

Calculation the mass attenuation coefficient of beta-particles through Polyvinyl chloride

open access: yesIraqi Journal of Physics, 2010
The mass attenuation coefficient for beta particles through pure Polyvinyl chloride (PVC) and flax fibers- reinforced PVC composite were investigated as a function of the absorber thickness and the absorber to source distance.

Heat Sterilizable Coatings Based on Nafion and Graphene Quantum Dots With Advanced Antibacterial Performance

open access: yesNano Select, EarlyView.
Electrostatically assembled layer‐by‐layer waterborne nanocoatings comprising negatively charged Nafion and positively charged imidazole modified‐graphene quantum dots can inhibit the growth of bacteria and can withstand dry heat sterilization without any decline in their activity.

Reclaiming Korean queerness through the gender bender drama: Analyzing gender fluidity in “Coffee Prince” and “Secret Garden”

open access: yesPopular Culture Review, EarlyView.
Abstract This thesis engages in a “queering” of two South Korean television dramas, “Coffee Prince,” or “커피 프린스 1호점,” aired in 2007, and “Secret Garden” or “시크릿 가든,” aired in 2010, by exploring the complex representations and visuality of gender fluidity in tandem with queer, Marxist, and postcolonial theory.
