Article Synopsis
  • - This work discusses the defect chemistry of rutile titanium dioxide (TiO) and explores how reversible atomic-size structural defects can be engineered for improved TiO-based energy materials, like photoelectrodes and photocatalysts.
  • - It emphasizes the importance of using thermodynamics in understanding and manipulating surface defects, which play a crucial role in enhancing reactivity and performance of these materials under operational conditions.
  • - The study introduces a high-temperature electron probe as a reliable tool for monitoring defect-related surface properties, leading to new insights into stable performance during processes like photoelectrochemical water splitting and the operation of solid oxide fuel cells.

Background: Bidirectional ventricular tachycardia (BVT) is a rare type of ventricular tachycardia that is characterized by a beat-to-beat alternation in the QRS axis. Previous studies have shown that it is caused by alternating focal activities from 2 locations.

Objective: This study proposes a novel mechanism for the formation of spatially discordant alternans (SDA) due to the periodic pacing site alternation that occurs in BVT.

Two of every three persons living with dementia reside in low- and middle-income countries (LMICs). The projected increase in global dementia rates is expected to affect LMICs disproportionately. However, the majority of global dementia care costs occur in high-income countries (HICs), with dementia research predominantly focusing on HICs.

Background: A body of research from around the world has reported positive effects of bilingualism on cognitive ageing and dementia. However, little is known about whether foreign language learning could be applied as an intervention for people already living with dementia. Yet, before it is possible to determine the efficacy of language courses as an intervention for people living with dementia (PLWD), it is necessary to establish whether such an intervention is feasible.

Article Synopsis
  • The study focused on primary progressive aphasia (PPA) in native Chinese speakers, highlighting the unique challenges posed by the classifier system in Chinese compared to Indo-European languages.
  • Results showed that both semantic variant (sv) PPA and logopenic variant (lv) PPA patients struggled significantly with classifier production, with lvPPA patients performing better in recognition tasks.
  • The findings indicate that classifier processing could serve as a linguistic marker for distinguishing between different PPA variants, with performance linked to specific brain regions involved in language and visual processing.
