Since Rayleigh’s early work on shear-flow driven instabilities in fluids, it has been known that sheared flows are usually unstable only in the presence of an inflection point in the velocity profile. However, in magnetohydrodynamics, there are important instabilities for which no inflection point is required. In tokamak experiments, strongly sheared flows are associated with transport barriers...

Many languages allow a pronoun to go unpronounced in the presence of inflectional marking for person and number. This paper explores the hypothesis that inflection may itself be ‘pronominal’ using data from Irish which exhibits a well-known complementary distribution between person/number inflection and pronouns. Such complementarity follows if inflection forms a syntactic chain with a pronoun ...

In pharmacy education, we are experiencing the “new normal” after an “inflection point” along with a host of other overused phrases. Yet, without doubt, there is pressing need to reconsider what was once standard operating procedure. When inflection point viewed as opportunity, it sparks strategic boom. Indeed, confluence threats and opportunities caused—or revealed—by COVID-19 pandemic setting...

Success of pig production depends on maximizing return over feed costs and addressing potential nutrient pollution to the environment. Mathematical modeling has been used to describe many important aspects of inputs and outputs of pork production. This study was undertaken to compare 4 mathematical functions for the best fit in terms of describing specific data sets on pig growth and, in a sepa...
