In a survey of dust devil activity at a desert playa using continuous monitoring by a pressure logger, we have detected a number of pressure drops with complex structures: simple and symmetric drops make up only 25–30% of the total. In contrast to the simple, symmetric single-dip profiles expected for singlecell vertical vortices gliding past the pressure sensor, many profiles have an asymmetri...

High telomerase activity is detected in nearly all human cancers but most human cells are devoid of telomerase activity. There is well-documented evidence that reactivation of telomerase occurs during cellular transformation. In humans, tumors can rely in reactivation of telomerase or originate in a telomerase positive stem/progenitor cell, or rely in alternative lengthening of telomeres, a tel...

The focus of this paper is on crafting a new visual language for attribute grammars (AGs), and on the development of the associated programming environment. We present a solution for rapid development of VisualLISA editor using DEViL. DEViL uses traditional attribute grammars, to specify the language’s syntax and semantics, extended by visual representations to be associated with grammar symbol...

To date, characterisation of dust devils by interpreting spectral measurements taken during a transit over a spectroscopic instrument has yet to be done and would provide valuable information of the physical size, dust load and internal structure of transiting dust devils. A Monte Carlo Radiative Transfer model (MCRT) was developed to investigate the spectral variations during a dust devil tran...

The autonomous transposable element LINE-1 is a highly abundant element that makes up between 15% and 20% of therian mammal genomes. Since their origin before the divergence of marsupials and placental mammals, LINE-1 elements have contributed actively to the genome landscape. A previous in silico screen of the Tasmanian devil genome revealed a lack of functional coding LINE-1 sequences. In thi...

When I went to medical school, I was taught that conceptually, the toxicity of doxorubicin and anthracyclines in general could be compared with that of acetaminophen, such that as long as I operated within “the safe dose,” patients with cancer would derive only benefits, not toxicity. I do not believe that my teachers are to be blamed for this thinking. If we take a look at the original von Hof...
