Single-crystalline Mg tips

This repository contains all input data for simulating the field-evaporation process of specifically oriented single-crystalline APT tips with representing h.c.p. magnesium using TAPSim. Having conducted all simulations, it contains all detector hit information for all ions and each tip. The authors have also personally stored the trajectories of all ions for each tip. However, given the size of these particular additional binary data (approx. 100 - 200GB), they have --- as a compromise --- not yet been uploaded.  They are available from the authors for free upon request. The individual components of the dataset are as follows, where the * is a placeholder/wildcard. *SX_DetectorHits.zip The simulation results here specifically all detector hit maps for each tip and the input files for tapsim *.cif The Crystallography Open Database file used to define the unit cell *MeshgenInput.tar.gz The compressed txt-based inputfiles for MESHGEN with which the inputfiles for TAPSim for each tip were generated. *TapsimInput.tar.gz the compressed binary inputfiles for TAPSim which specify at which locations the atoms and mesh supporting points are located *BaseAndTip.zip The compressed PNG-renditions of where the tip ions and the base plate supporting points are located. The potential Moire effects apparent in the images are likely related to us reducing the rendering resolution. *Everything.zip The compressed PNG-renditions of where the tip ions, the base plate supporting points, and mesh points are located. *Meta.mat and *PRNG.txt The MATLAB workspace variables which hold the orientation of each tip as a rotation matrix and the seed of the random number generator. The rotation matrix is of active sense premultiplying point position vectors from the VESTA output into their actual locations from which subsequently the tip was carved. A few tip orientations did not run, this was solved by rotating them by an additional 0.5 deg random rotor in space about the projected orientation, the corresponding individual rotation matrices are stored in individual *.mat files with the corresponding tip ID in the filename each *.vesta The Vesta inputfile with which sufficiently sized lattice point clouds were written out to subsequently rotate them and carve into a tip. *DetectorHits.tar.gz The compressed raw data in the default TAPSim format encoding where each ion hit the detector surplus additional pieces of information. *.pl Perl scripts with which to extract runtime profile information from the TAPSim command line output *.sh Shell scripts used to execute the batch queue. Two scripts were used. The first, "run_queue_tapsim_job.sh" $1 $2 fires off independent sequential TAPSIM simulations on existent data The second "run_single_tapsim_job.sh" is called by the first script to fire this of. tapsim_r3225.zip The source code used to execute the simulations The *.tar.gz files in the *.zip archives can be unpacked with the unpack_dataset.sh shell script specifically unpack_dataset.sh $1 $2 with the first argument $1 the start ID and the second argument $2 being the tip end ID to unpack. Modification of the script might be necessary if file name of *.tar.gz archive has been changed... Single *.tar.gz files in general can be most conveniently extracted with a Unix/Linux operating system via for instance the command: tar -xvf nameofthefile.tar.gz On Windows WinRAR can be used for decompression

Reevaluated P-V-T Dataset for (Mg,Fe)SiO3 post-Perovskite

This is a collection of pressure, volume, and temperature data for (Mg,Fe)SiO3 post-perovskite collected in laser-heated diamond anvil cells.  The volumes and temperatures are collected from previous studies, and the pressures are reevaluated according to the internally consistent pressure scale of Dorogokupets and Dewaele (2007).  A Monte Carlo sampling routine was used to propagate uncertainty from the measured volumes and temperatures, as well as uncertainties in the pressure scale parameters, to the final pressure uncertainties.

LOPT input files for Mg VII and Si VII

This entry contains input files for the LOPT atomic physics code. The results are described in the article "Updated reference wavelengths for Si VII and Mg VII lines in the 272--281 Angstrom range" by Dr. Peter R. Young (NASA Goddard Space Flight Center) that was submitted to The Astrophysical Journal.There are two sub-directories called mg7 and si7 for the two ions. In each there are three input files of the form:Mg7_FixLEV_EIS.txt - List of fixed levels in the atomic model. Mg7_lin_EIS.prn - List of wavelengths and uncertainties for the lines of the model. Mg7_lopt_EIS.par - The parameter input file for LOPTYou will need to install the LOPT code to use these files. See Kramida, A. E. 2011, Computer Physics Communications,236 182, 419.In each directory you will see two additional files that are the output wavelength and energy files generated by the author.Version 1.1: the input/output filenames in the Mg7_lopt_EIS.par were wrong in the previous version. This has been fixed. The input data are the same as before.

Effect of Nd on high temperatures deformation and corrosion behavior of AZE Mg alloy

An extruded AZE Mg alloy (Mg-3Al-1Zn-0.6Nd) has been developed and prepared to examine the effect of the precipitated phase on corrosion and hot deformation behavior. High-temperature compression experiments show that dynamic recrystallization (DRX) occurs at various experimental parameters (473 to 673 K and 1×10-4 s-1 to 1×10-3 s-1). The deformation mechanism is dominated by dislocation slip and/or twinning. Al11Nd3 precipitates with two different sizes could impede nucleation and the growth of DRXed grains. Serrated flow occurred owing to the interactions between dislocations and precipitates. The corrosion current density decreases with the addition of Nd elements. Moreover, the continuous precipitation of the Al11Nd3 phase at grain boundaries reduces the corrosion rate in NaCl solution, thereby enhancing the corrosion resistance of AZE alloys.

Analysis of particles size distributions in Mg(OH)2 precipitation from highly concentrated MgCl2 solutions

Magnesium is a raw material of great importance, which attracted increasing interest in the last years. A promising route is to recover magnesium in the form of Magnesium Hydroxide via precipitation from highly concentrated Mg2+ resources, e.g. industrial or natural brines and bitterns. Several production methods and characterization procedures have been presented in the literature reporting a broad variety of Mg(OH)2 particle sizes. In the present work, a detailed experimental investigation is aiming to shed light on the characteristics of produced Mg(OH)2 particles and their dependence upon the reacting conditions. To this purpose, two T-shaped mixers were employed to tune and control the degree of homogenization of reactants. Particles were analysed by laser static light scattering with and without an anti-agglomerant treatment based on ultrasounds and addition of a dispersant. Zeta potential measurements were also carried out to further assess Mg(OH)2 suspension stability.

Figure 6.Amygdala hypofunction after a single oral 40-mg dose, 1.5-hours post-dose, in young study participants.The image has been adapted from (Hurlemann et al., 2010).-The Brain and Propranolol Pharmacokinetics in the Elderly

In the past decade, there has been much interest in identifying treatment in adding to the current treatment options for war veterans suffering from Post-Traumatic Stress Disorder (PTSD). The studies investigating secondary-preventative measures for PTSD using Propranolol due to the drug’s ability to inhibit the actions of the neurotransmitter norepinephrine,which has been implicated to enhance the consolidation(McGhee et al., 2009; Pitman et al., 2002; Stein et al., 2007).Further, in a double-blind, placebo-controlled,functional Magnetic Resonance Imaging (fMRI) study, in healthy volunteers, Hurlemann et al. found that a single oral 40mg dose of propranolol attenuatedthe leftbasolateral amygdala responses to the face perception paradigm(Hurlemann et al., 2010). The study participants were eighteen healthy (9 females, 9 males; mean age 23 years; age range 19–31 years) who had their fMRI acquisition 1.5-hours after the oral administration of propranolol. An adapted image of the study findings are shown in Figure 6.
