This paper studies the notions of conceptual grounding and explanation (which includes notion mathematical explanation), with an aim clarifying links between them. On one hand, it analyses complex examples these two that bring to fore features are easily overlooked otherwise. other provides a formal framework for modeling both explanation, based on concept proof. Inspiration analogies drawn rec...

There are two ways eukaryotes double number of chromosomes: (1) whole genome duplication (polyploidy), in which all nuclear DNA is replicated, and (2) karyotypic fission (pseudopolyploidy), in which all chromosomes are physically bifurcated. We contrast polyploidy with pseudopolyploidy, highlighting when it is crucial to look at genetic vs. genomic levels. We review history of pseudopolyploidy,...

Carbon–carbon bond formation is the core of organic synthesis, in which organometallic reagents play key role forms 1,2-nucleophilic additions, conjugate and transition-metal catalyzed cross-couplings. These reactions have enabled production a wide range molecules our society. Despite enormous power chemical they inherent drawbacks eyes future sustainability. This account summarizes efforts ove...

A name cannot change the city and our relationship with places. However, new terms for now-nameless spaces will help to change people’s perception and their capability of seeing what they have never seen before. The geographer’s taxonomic effort to re-designate urban places and typologies involves a political and ideological content. Most urban spaces are unmanageable because they fit neither w...
