The use of VX as a terrorist agent: action by Aum Shinrikyo of Japan and the death of Kim Jong-Nam in Malaysia: four case studies

open access: yes, 2020
VX is a strong nerve-gas agent. In this paper, murder or injury of human made by VX is reported. First use of VX against human was made by Aum Shimrikyo in 1994 and 1995. More recently, VX was used in the assassination of Mr. Kim Jong-Nam in Kuala Lumpur,

Design of Compact Liquid Crystal on Silicon Projection Optics Utilizing a Common Freeform Optical Path for Augmented Reality Displays

open access: yesAdvanced Intelligent Systems, EarlyView.
This study presents a compact freeform projection optics using dual wedge prisms for waveguide displays. Unlike previous designs that separate illumination and imaging paths, a freeform optical path integrates both. The system achieves a 32º field of view, 37.5 pixels per degree, and a total volume of less than 2 cm3.

Correlation Between Vinyl Content of Recycled HDPE and Polymer Degradation: An NMR Approach

open access: yesJournal of Applied Polymer Science, EarlyView.
The degradation behavior of high‐density polyethylene (HDPE) during recycling depends on its vinyl group content. This study shows that 1H NMR spectroscopy enables accurate assessment of vinyl groups unlike FTIR. Changes in melt flow and molecular weight with multiple processing are linked to vinyl content which could enable tailor‐made re‐additivation

Non-Collinear Magnetic Phases of a Triangular-Lattice Antiferromagnet and Doped CuFeO$_2$

open access: yes, 2009
We obtain the non-collinear ground states of a triangular-lattice antiferromagnet with exchange interactions up to third nearest neighbors as a function of the single-ion anisotropy $D$. At a critical value of $D$, the collinear $\uudd $ phase transforms

Loss of Tripartite Motif–Containing Protein 21 and UVB‐Induced Systemic Inflammation by Regulating DNA‐Sensing Pathways

open access: yesArthritis &Rheumatology, EarlyView.
Objective Patients with systemic lupus erythematosus (SLE) experience photosensitivity, with exposure to UVB light driving lupus flares and triggering symptoms like joint pain, fatigue, and cutaneous lesions. Although the mechanism(s) linking UVB exposure to systemic effects are unclear, type I interferons (IFNs) are known to play a role.

Magnetic Fields in Evolved Stars: Imaging the Polarized Emission of High-Frequency SiO Masers

open access: yes, 2011
We present Submillimeter Array observations of high frequency SiO masers around the supergiant VX Sgr and the semi-regular variable star W Hya. The J=5-4, v=1 28SiO and v=0 29SiO masers of VX Sgr are shown to be highly linearly polarized with a ...
