Clinical considerations in the application of direct composite for tooth wear

Various techniques are available for the application of composite to restore worn teeth. Different techniques may be chosen based on the clinical presentation or clinician preference. However, for composite to be successful, there are numerous factors which must be considered in order to optimise the outcome. Pre-treatment steps, such as isolation for optimal moisture control and adequate surface preparation of the tooth, as well as the post build-up objectives of achieving a stable occlusion, good marginal adaptation and final aesthetics, are discussed in the paper.

Digital transformation of droplet/aerosol infection risk assessment realized on "Fugaku" for the fight against COVID-19

The fastest supercomputer in 2020, Fugaku, has not only achieved digital transformation of epidemiology in allowing end-to-end, detailed quantitative modeling of COVID-19 transmissions for the first time but also transformed the behavior of the entire Japanese public through its detailed analysis of transmission risks in multitudes of societal situations entailing heavy risks. A novel aerosol simulation methodology was synthesized out of a combination of a new CFD methods meeting industrial demands in the solver, CUBE (Jansson et al., 2019), which not only allowed the simulations to scale massively with high resolution required for micrometer virus-containing aerosol particles but also enabled extremely rapid time-to-solution due to its ability to generate the digital twins representing multitudes of societal situations in a matter of minutes, attaining true overall application high performance; such simulations have been running for the past 1.5°years on Fugaku, cumulatively consuming top supercomputer-class resources and the communicated by the media as well as becoming the basis for official public policies.
