A favorable regime of H-mode confinement, seen on the Alcator C-Mod tokamak is described. Following a brief period of ELM-free H-mode, the plasma evolves into the Enhanced D-Alpha (EDA) H-mode which is characterized by very good energy confinement, the complete absence of large, intermittent type I ELMs, finite impurity and majority species confinement, and low radiated power fraction. Accompan...
We show that the cooperative reinforcement between hydrogen bonds in guanine quartets is not caused by resonance-assisted hydrogen bonding (RAHB). This follows from extensive computational analyses of guanine quartets (G(4)) and xanthine quartets (X(4)) based on dispersion-corrected density functional theory (DFT-D). Our investigations cover the situation of quartets in the gas phase, in aqueou...
In this research, the thermal stability and decomposition kinetics of pentaerythritol tetranitrate (PETN) and Pentastite explosives have been studied experimentally using non-isothermal differential thermal analysis (DTA) and thermo-gravimetric (TG) methods at heating rates of 4.0, 6.0, 8.0 and 10.0 °C/min. The kinetic parameter of activation energy (Ea) and critical ignition temperature fo...
The advantages of EDA H-modes include good energy confinement and no impurity accumulation or large ELMs. In EDA, the edge pressure gradients are at or above the ideal ballooning limit but are not relaxed by type I ELMs; instead a continuous process would seem to be at work. This process is probably related to broadband and quasi-coherent fluctuations which are seen with reflectometry, probes, ...
Exploratory Data Analysis (EDA) and Confirmatory Data Analysis (CDA) are two statistical methods widely used in scientific research. They are typically applied in sequence: first, EDA helps form a model or a hypothesis to be tested, and then CDA provides the tools to confirm if that model or hypothesis holds true. When both analyses are applied within a single experiment, two main types of erro...
DFT investigations have been carried out on encapsulation of Lindqvist-type W(6)O(19)(2-) anion inside hydrogenated (n,n) armchair single-walled carbon nanotubes (h-CNTs) with n = 8, 9, 10 to understand the confinement effect of the CNTs on the rotation of W(6)O(19)(2-). The energy-decomposition analysis (EDA) of interaction between W(6)O(19)(2-) and CNTs shows that with the increase of confine...
The cation binding strength of calix[4]pyrroles in the gas phase has been evaluated by computational studies and further substantiated by ESI mass spectrometry experiments. The DFT optimized geometries of [CP + X](+) complexes are found to be stable in a 1,3-alternate conformation through cation-π interactions and interestingly CPs are found to be better cation receptor than calix[4]arenes. The...
Electrodermal activity (EDA) is considered a measure of autonomous nervous system activity. This study performed an exploratory analysis of the EDA changes during blood pooling for arterial blood gas analysis in sedated adult critical care patients and correlated the variations to other monitored parameters. EDA, along with other parameters, were monitored during 4 h routine daytime intensive c...
