An evaluation of root phytochemicals derived from Althea officinalis (Marshmallow) and Astragalus membranaceus as potential natural components of UV-protecting dermatological formulations [PDF]

open access: yes, 2016
Open access journalAs lifetime exposure to ultraviolet (UV) radiation has risen, the deleterious effects have also become more apparent. Numerous sunscreen and skincare products have therefore been developed to help reduce the occurrence of sunburn ...

Cooperative Heterogeneous Deep Reinforcement Learning [PDF]

open access: yesarXiv, 2020
Numerous deep reinforcement learning agents have been proposed, and each of them has its strengths and flaws. In this work, we present a Cooperative Heterogeneous Deep Reinforcement Learning (CHDRL) framework that can learn a policy by integrating the advantages of heterogeneous agents.

ENHANCING THE SUNSCREEN EFFICACY OF BEMOTRIZINOL MICROPIGMENT BY USING O/W NANOEMULSION TOPICAL PREPARATIONS [PDF]

open access: yes, 2019
Objective: Bemotrizinol (BEMT) is the most efficient broad-spectrum UV-absorber having a dual mechanism of action in absorbing and reflecting photons. The main objective of this work was to develop successful oil in water (o/w) nanoemulsion for improving

QuaRTz: An Open-Domain Dataset of Qualitative Relationship Questions [PDF]

open access: yesarXiv, 2019
We introduce the first open-domain dataset, called QuaRTz, for reasoning about textual qualitative relationships. QuaRTz contains general qualitative statements, e.g., "A sunscreen with a higher SPF protects the skin longer.", twinned with 3864 crowdsourced situated questions, e.g., "Billy is wearing sunscreen with a lower SPF than Lucy.
