Strong Lensing of Gravitational Waves as Seen by LISA [PDF]

Physical Review Letters, 2010
We discuss strong gravitational lensing of gravitational waves from merging of massive black hole binaries in the context of the LISA mission. Detection of multiple events would provide invaluable information on competing theories of gravity, evolution and formation of structures and, with complementary observations, constraints on H_0 and other ...

Self‐Assembled Heterosymmetric Structure with Tunable Polarization Optics for Reversible Matrix Encryption

Advanced Functional Materials, EarlyView.
Sustainable films with heterosymmetric structures, harmoniously integrating symmetry and asymmetry, are fabricated using cellulose nanocrystals and hydrophilic nanolignin via evaporation‐induced self‐assembly, which exhibit excellent multiple polarization optical properties.

Inverted PAINT for Material‐Specific Super‐Resolution Fluorescence Imaging of Semiconductors

Advanced Materials, EarlyView.
This study presents Inverted PAINT, a label‐free super‐resolution fluorescence imaging method optimized for thick and non‐transparent semiconductor materials. By employing electrostatic dye–surface interactions in an inverted geometry, the technique enables material‐specific, multicolor, and 3D nanoscale imaging, with applications in semiconductor ...

Gravitational lensing by a charged black hole of string theory

, 2003
We study gravitational lensing by the Gibbons-Maeda-Garfinkle-Horowitz-Strominger (GMGHS) charged black hole of heterotic string theory and obtain the angular position and magnification of the relativistic images. Modeling the supermassive central object

Strong gravitational lensing’s ‘external shear’ is not shear [PDF]

Monthly Notices of the Royal Astronomical Society
ABSTRACT The distribution of mass in galaxy-scale strong gravitational lenses is often modelled as an elliptical power-law plus ‘external shear’, which notionally accounts for neighbouring galaxies and cosmic shear along our line of sight.

Targeted Local Delivery via Fiber‐Embedded Flexible Microchannels Integrated with Film‐Based Implantable Probes

Advanced Materials Technologies, EarlyView.
In this study, a fiber‐embedded drug delivery channel for implantable microprobes, demonstrating the first functional drug delivery system using flexible LCP‐based probes, is developed. The design incorporates fibers for site‐selective drug delivery and electrical functions. The utilization of monolithic thermal bonding simplifies fabrication.

Macroscopic Phase‐Change Drug Carrier Ball with Photothermally Controlled Release and Magnetically Controlled Transport Properties

Advanced Materials Technologies, EarlyView.
Millimeter‐scale macroscopic phase‐change balls with on‐demand drug release triggered by photothermal stimulation and magnetically controllable transport properties are demonstrated. The proposed system can be easily fabricated using omniphobic surfaces and offers several advantages, including high visibility, controllable transport, easy drug loading,
