Efficient Removal Without Efficient Regularity [PDF]
Combinatorica, 2019 Obtaining an efficient bound for the triangle removal lemma is one of the most outstanding open problems of extremal combinatorics. Perhaps the main bottleneck for achieving this goal is that triangle-free graphs can be highly unstructured. For example, triangle-free graphs might have only regular partitions (in the sense of Szemer di) of tower-type ...

Phytoremediation potential of indoor plants in reducing air pollutants
Frontiers in Sustainable Cities, 2022 Indoor air quality (IAQ), specifically after the COVID-19 pandemic, has become an international issue, as humans spend 80–90% of their time in indoor microenvironments. Poor IAQ has been related to the sick-building syndrome, nasal and ocular irritations,
