... Fig.1 The He number density for equilibrium He bubble at 300K. The green and red dots correspond to the unsaturated and saturated state, respectively. Fig.2 The pressure of equilibrium He bubbles with d and He/vacancy ratios at 300K. The He bubbles reach to the saturated state when He/vacancy ratios increases to 0.85 for all sizes. The pressure of unsaturated He bubbles increases as He/vacancy ratio increases, whereas the pressure of saturated He bubbles tends to be stable with some fluctuation. Fig.3 The relationship between the bubble pressure and volume at different temperatures. The Y-L equation, even considering the finite width of the interface, is no longer agrees well with the saturated He bubble unless the temperature exceeds the melting point of samples. The state of unsaturated He bubbles approximates the ideal gas EOS. A modified EOS containing the correction terms of temperature and volume is proposed to describe the saturated He bubbles. Fig.4 The variation of volume with the number of He atoms (N) . The results show a near-linear relationship between volume and the number of He atoms both in unsaturated and saturated state. The modified EOS agrees well with the MD results for N<15000. Fig.5 The relaxation process of He bubbles for different He/vacancy ratios (r) . A closed stacking fault octahedron is formed for r=1, while the closed SFO is insufficient to keep He bubble stability for r=1.5. Fig.6 The microstructure of the Al matrix induced by the equilibrium He bubbles with different initial configurations. Upper: the diameters of He bubbles are 1nm, 2nm, 3nm, 4nm and 5nm, respectively. Fig.7 The morphologies of He bubbles with d and r at 300K. Upper: the diameters are 1nm, 2nm, 3nm, 4nm and 5nm,respectively. Fig.8 The local lattice environment of He bubble on (111) plane at different temperatures. Atoms are color-coded by their local lattice structure (FCC (green), HCP (red) and disordered (white)) as obtained from dislocation extraction algorithm(DXA). The shape of He bubble shows a strong temperature dependence: (A)irregular polygon; (B)further deformation; (C)hexagon; (D)circle. Fig.9 (A)Sketch of the octahedral stress; (B)Sessile junctions obtained by removing the atoms of τ<2GPa Fig.10 The shear stress-field nephogram around He bubbles.The nephograms show the shear stress-field inhomogeneously increases as the increasing d and r. Besides, the domain of shear stress field increases as the increasing d and r. Fig.11 No dislocation atoms are found in unsaturated state. The number of dislocation atoms is nearly linear with N in saturated state.

... Architectural Design is a core component in Architecture, Engineering, Construction and Operations collaborative. With the arrival of Artificial Intelligence, the industry is pushing for smart and sustainable solutions. The corresponding mechanism of teaching young Architects to design in immersive environments requires a overhaul of the studio pedagogy. The taxonomy of computer augmented studio is under investigation with acceptability to computing technology and tools.

... These design files and LabVIEW VIs contained in this dataset allow sea ice and iceberg researchers to replicate the IceDrone. The IceDrone is a student-built, unmanned ice sampling system that was designed to acquire ice samples from high-risk environments, like icebergs and thin sea ice. IceDrone is relatively small and portable and can be operated with little support infrastructure, which frees up research equipment on icebreakers, like baskets and helicopters, for other research activities. IceDrone is built around the commercially available DJI Matrice 600 Pro (M600) hexcopter. The M600 is modified to carry a custom ice coring system and landing gear. The files presented here are separated into versions. Versions 1 and 2 include the initial design, and upgrades that were made after a field test, respectively. Version 1 includes the basic design files and describes the overall construction of IceDrone. Version 2 includes upgrades to the ice core drill design, laser range finders to regulate descent speed, automated drill motor control, vibration dampening for the camera/gimbal system, and a 3D printed enclosure for the electronics.

... Version 1.0, September 9, 2019 Purpose: Created as part of a project funded by NASA’S Lunar Data Analysis Program (LDAP), the purpose of this dataset is to provide locations and diameters of boulders around small, young impact craters on the Moon. These boulder counts were conducted as part of a study aimed at determining regolith production rates and assessing landing site hazards, as discussed in the associated publications. Researchers are encouraged to read the publications and data description document to understand how the data was acquired and used. This database contains boulder distributions around small (< 1 km), young (< 200 Ma) lunar impact craters located near spacecraft landing sites. The most up-to-date database contains boulder diameters and coordinates for counts around Surveyor (Apollo 12), Cone (Apollo 14), North Ray (Apollo 16), South Ray (Apollo 16), Camelot (Apollo 17), and Zi Wei (Chang’e-3) craters. Boulders were manually identified and measured on Lunar Reconnaissance Orbiter Camera (LROC) Narrow Angle Camera (NAC) images (Robinson et al., 2010) at scales of ~0.5-2 m/pixel. LROC NAC images allow for boulders ~1-2m in size and larger to be identified and measured. The tools for measuring boulders were CraterTools (Kneissl et al., 2011) and Crater Helper Tools (Nava, 2011), both developed for the ArcMap GIS platform. These boulder distributions are being used to understand boulder degradation rates on the lunar surface, and to assess landing site hazards for future surface missions to the Moon. This dataset is being archived in Mendeley Data and at the Planetary Data System (PDS) Cartography and Imaging Node for use in future boulder distribution and landing hazard studies. Future boulder counts and any refinements to existing measurements will be uploaded into subsequent versions of this dataset here and at the PDS IMG Annex: https://astrogeology.usgs.gov/search/map/Moon/Research/Regolith/lunar_boulder_data_bundle

... Method 1: L-CSNO binding to proteins after native-PAGE separation The mouse brain membrane fraction (above) was resuspended in HEPES buffer. A BCA (Pierce) protein assay was performed and 50 µg protein was run on two native-PAGE gels (TGX, Bio Rad). One gel was incubated for 30 min in the dark with 50 µM L-CSNO in S-nitrosothiol buffer (10 mM Tris-HCl, pH 6.0, 150 mM NaCl). The second gel was incubated for 30 min in the dark with 50 µM L-CSNO and 100 µM each S-phenyl-cysteine (L-CSφ) and S-methyl-cysteine (L-CSMe) in S-nitrosothiol buffer. Each gel was then rinsed with water and incubated in the dark with 40 µM diaminofluoroscein (DAF) 2 (Cayman Chemicals) for 10 min in the dark (RT) (24). Gels were then imaged on Chemidoc (Bio Rad; Hercules, CA) using the fluorescein setting and bands cut out for mass spectrometry proteomics (see below) that were seen without, but not with, the S-methyl and S-phenyl substituted cysteine co-incubations (21). Method 2: L-CSNO affinity chromatography L-CSNO affinity columns were prepared as follows. L-Cysteine was coupled to AminoLink Plus (Pierce/ThermoFisher; Waltham, MA) resin according to the manufacturer’s protocol. In control experiments, aminoLink Plus was used without reaction with L-cysteine. Briefly, L-cysteine was dissolved in coupling buffer A (0.1 M sodium citrate, 0.05 M sodium carbonate, pH 10) at a concentration of 100 mM and incubated with 0.4 ml, previously washed, AminoLink resin in a small (0.5 ml) column for 4 hours at room temperature. The resin was then washed with coupling buffer B (0.1 M phosphate. 0.15 M sodium chloride, pH 7.2) and incubated for 4 hours at room temperature with 100 mM cyanoborohydride in coupling buffer B. Active sites were then blocked with quenching buffer (1 M Tris-HCl, pH 7.4). Resin was then washed with 1 M NaCl and then incubated for 10 min with 30% ethyl nitrite (EtONO) in ethanol at room temperature in the dark (25). It was then washed with 100% ethanol followed by 1M NaCl. Excised mouse brain homogenate was briefly centrifuged and the supernatants were then incubated with prepared Aminolink columns for 30 min at room temperature. The columns were then washed with wash buffer and bound protein eluted with Laemmli buffer and elution buffer (0.1 M Glycine, pH 3.5). Eluate was concentrated and used for SDS-PAGE gel (TGX, BioRad; Hercules, CA) followed by Coomassie staining. Bands found in samples from + L- Cysteine columns but not in – L-cysteine columns were excised and analyzed further by MS proteomics. Biotin substitution analysis for NO-substituted cysteine’s in Kv proteins CHO cells expressing all three Kv proteins were plated on in 6 wells of a six well plate. Once confluent, cells were incubated with no treatment, 500 µM L-CSNO, or 500 µM L-CSNO plus 10mM leucine for two minutes. Wells were then washed with cold PBS and lysed in HEN buffer (250mM HEPES pH7.7, 1mM EDTA, 0.1mM Neocuproine). After biotin switch, samples went to LC-MS.
