The CRISPR/Cas9 technology is a welcome breakthrough for genome editing, owing to its precision, efficiency, versatility and ease of adoption. We recently reported the first application of CRISPR/Cas9 for biallelic mutations in stably transformed Populus, extending the species range of this powerful technology to woody perennials. An underappreciated obstacle in genome editing of outcrossing sp...

We introduce a new invariant S (M) for type III factors M with no almost-periodic weights. We compute this invariant for certain free Araki-Woods factors. We show that Connes’ invariant τ cannot distinguish all isomorphism classes of free Araki-Woods factors. We show that there exists a continuum of mutually non-isomorphic free Araki-Woods factors, each without almostperiodic weights.

The theory of internal tidal waves is briefly reviewed in order to demonstrate the importance of simultaneous observations at different positions. After a description of the expectancy test it is shown that a reasonably high probability exists that the internal tidal oscillations found at Meteor Station 385 in the temperature observations are real and not purely formal results of the harmonic a...

Schnyder woods are particularly elegant combinatorial structures with numerous applications concerning planar triangulations and more generally 3-connected planar maps. We propose a simple generalization of Schnyder woods from the plane to maps on orientable surfaces of any genus with a special emphasis on the toroidal case. We provide a natural partition of the set of Schnyder woods of a given...

Indigenous entrepreneurship is an emerging field of study within the broader field of entrepreneurship. While it is acknowledged that indigenous entrepreneurial activity comes from a particular cultural context, what is not so well understood is how it emerges and how historical context and cultural heritage inform the activity (Peredo & Anderson et al 2006). This was addressed briefly within E...

Tiger Woods has an amazing record of winning golf tournaments. He has gained the persona of a player that is a winner, a player that when near the lead or in the lead can do whatever it takes to win. In this paper I investigate whether in fact, he is a winner. A mathematical model is created for the ability of Tiger Woods, and all PGA Tour golfers to play 18 holes of tournament golf. The career...
