TL;DR: The cyclic tetra-aza complexones cDOTA, cTRITA and cTETA have been synthesized and characterized by elemental analysis, titration, melting-point determination and NMR (and infrared) spectroscopy and neither this ligand nor the other two offer advantages over EDTA or DCTA for the complexometric titration of transition metals.

TL;DR: In this article, the authors examined whether founders' backgrounds influence new firm survival in the early years after startup, focusing on the impact of unemployment-driven entrepreneurship, and found that pre-entry capabilities play an important role in the success of opportunity-based entrepreneurs, but have little influence on the early success of necessity-based ones.
Abstract: This paper examines whether founders’ backgrounds influence new firm survival in the early years after startup, focusing, in particular, on the impact of unemployment-driven entrepreneurship. For entrepreneurs who left their previous employment to found a new firm, both general and specific human capital play a key role in enhancing early survival chances. However, various forms of human capital have little effect on early survival of unemployment-driven entrepreneurs, who rely mostly on previous entrepreneurial experience to persevere. Results suggest that pre-entry capabilities play an important role in the early success of opportunity-based entrepreneurs, but have little influence on the early success of necessity-based ones.

TL;DR: Reflectometry applied to the measurement of density profiles on fusion plasmas has been subject to many recent developments as discussed by the authors, and different techniques used for reflectometry are grouped into three different categories, depending on the frequency spectrum of the probing wave.
Abstract: Reflectometry applied to the measurement of density profiles on fusion plasmas has been subject to many recent developments. After a brief reminder of the principles of reflectometry, the theoretical accuracy of reflectometry measurements is discussed. The main difficulties limiting the performance, namely the plasma fluctuations and the quality of the transmission lines, are analysed. The different techniques used for reflectometry are then presented grouped into three different categories, depending on the frequency spectrum of the probing wave: single frequency, few discrete frequencies, or broad spectrum. The present status and achievements of actual implementations of these techniques are demonstrated, with an analysis of their respective limitations and merits, as well as foreseen developments. Finally, a discussion of the various reflectometry techniques is made, in particular their ability to cope with plasma fluctuations and complex transmission lines, in view of the application to next step machines and very severe environments.
