Time temperature superposition of the dissolution of cellulose fibres by the ionic liquid 1-ethyl-3-methylimidazolium acetate with cosolvent dimethyl sulfoxide

open access: yesCarbohydrate Polymer Technologies and Applications, 2021
The dissolution of cellulosic flax fibres in the ionic liquid 1-ethyl-3-methylimidazolium acetate ([C2mim][OAc]) with cosolvent dimethyl sulfoxide (DMSO) has been studied.

Rheology of Green Plasticizer/Poly(vinyl chloride) Blends via Time–Temperature Superposition

open access: yes, 2017
Plasticizers are commonly added to poly(vinyl chloride) (PVC) and other brittle polymers to improve their flexibility and processing properties. Phthalate plasticizers such as di(2-ethylhexyl phthalate) (DEHP) are the most common PVC plasticizers and ...

Specific features of the principle of the time-temperature superposition in low density polyethylene filled with shungite

open access: yesТонкие химические технологии, 2013
The time dependence of the mechanical losses of low density polyethylene (LDPE) filled with fine particles of shungite in the process of periodic dynamic loading at changing frequency of loading and temperature was studied.

The dynamical evolution of exciton-polaritons in asymmetric ring-step potential well

open access: yesNew Journal of Physics
The exciton-polariton, a quasi-particle formed by the coupling of excitons and photons, exhibits a semi-light-semi-matter nature, inheriting the advantages of both constituents and capable of achieving Bose-Einstein condensation at room temperature. This

Few-shot Named Entity Recognition via Superposition Concept Discrimination [PDF]

open access: yesarXiv
Few-shot NER aims to identify entities of target types with only limited number of illustrative instances. Unfortunately, few-shot NER is severely challenged by the intrinsic precise generalization problem, i.e., it is hard to accurately determine the desired target type due to the ambiguity stemming from information deficiency.
