Probing satellite haloes with weak gravitational lensing [PDF]
Monthly Notices of the Royal Astronomical Society, 2012 We demonstrate the possibility of detecting tidal stripping of dark matter subhalos within galaxy groups using weak gravitational lensing. We have run ray-tracing simulations on galaxy catalogues from the Millennium Simulation to generate mock shape catalogues. The ray-tracing catalogues assume a halo model for galaxies and groups, using various models

Automated Fabrication of 3D Printed Magnetic Soft Robots With Programmable 3D Magnetizations
Advanced Robotics Research, EarlyView.An automated 3D printer for fabricating magnetic soft robots is shown to program 3D magnetizations into a composite elastic resin. Printer parameters, such as geometric resolution and deflection angles, are characterized and a fast repeatable production process was demonstrated.

Combined reconstruction of weak and strong lensing data with WSLAP [PDF]
Mon.Not.Roy.Astron.Soc.375:958-970,2007, 2005 We describe a method to estimate the mass distribution of a gravitational lens and the position of the sources from combined strong and weak lensing data. The algorithm combines weak and strong lensing data in a unified way producing a solution which is valid in both the weak and strong lensing regimes.

Advanced Science, EarlyView.Grain orientation in Nd2NiO4+δ ceramic membranes, achieved using magnetic fields, enables precise tuning of oxygen transport properties. This study presents an Nd2NiO4+δ bulk membrane with grains aligned with their a,b‐plane parallel to the oxygen permeation direction, produced by a neodymium magnet.

Weak Gravitational Lensing and Its Cosmological Applications [PDF]
Annual Review of Nuclear and Particle Science, 2008 Weak gravitational lensing is a unique probe of the dark side of the universe: It provides a direct way to map the distribution of dark matter around galaxies and clusters of galaxies as well as on cosmological scales. Furthermore, the measurement of the weak lensing–induced distortions of the shapes of distant galaxies is a potentially powerful probe

Advanced Microfluidic‐Based Wearable Electrochemical Sensors for Continuous Biochemical Monitoring
Advanced Electronic Materials, EarlyView.Microfluidic‐based wearable electrochemical sensors are transforming non‐invasive health monitoring through real‐time biochemical analysis of sweat, saliva, and interstitial fluid. This review explores advances in microfluidic design, fabrication, and sensor integration while addressing biofluid variability, material compatibility, and scalability.

Light on dark matter with weak gravitational lensing [PDF]
IEEE Signal Processing Magazine, 2010 This paper reviews statistical methods recently developed to reconstruct and analyze dark matter mass maps from weak lensing observations. The field of weak lensing is motivated by the observations made in the last decades showing that the visible matter represents only about 4-5% of the Universe, the rest being dark.

Tackling ignorance about law in human rights education
British Educational Research Journal, EarlyView.Abstract This paper aims to unpack potential reasons why law and legal knowledge—despite its apparent importance and value in teaching and learning about human rights—appears to be largely conspicuous by its absence in human rights education (HRE) in schooling.

The Ray Bundle method for calculating weak magnification by gravitational lenses [PDF]
, 1998 We present here an alternative method for calculating magnifications in gravitational lensing calculations -- the Ray Bundle method. We provide a detailed comparison between the distribution of magnifications obtained compared with analytic results and conventional ray-shooting methods.

ChemPhysChem, EarlyView.Porous ionic liquids display dissimilar rheological behavior when prepared with the same porous solid, the same volume fraction, and two different ionic liquids varying only the anionic species. Abstract The rheological behavior of porous ionic liquids comprising ZIF‐8 suspensions in two Newtonian ionic liquids – trihexyltetradecylphosphonium bis ...
