Impact of Leadless Pacemaker Implantation Position on Subclinical Right Ventricular Perforation
Pacing and Clinical Electrophysiology, EarlyView.ABSTRACT Introduction Leadless pacemakers are typically implanted in the mid‐septum of the right ventricle (RV) to mitigate the risk of perforation. However, reports on the precise location of these implants are limited. This study aimed to elucidate tine‐based leadless pacemaker position and presence of subclinical RV perforation through computed ...

A New Concept of “Kim Jong Un Partizan” Discourse and Authoritarian Durability in North Korea
Pacific Focus, EarlyView.ABSTRACT How does the North Korean regime secure elite loyalty without institutional transparency or material redistribution? While existing studies have examined the use of Partizan narratives under Kim Il Sung and Kim Jong Il, this paper argues that Kim Jong Un introduces a significant discursive shift: the invention of “Kim Jong Un Partizans.” This ...

Spectral Singularities in the Surface Modes of a Spherical Gain Medium
, 2013 We study the surface modes of a homogeneous spherical gain medium and provide a comprehensive analytic treatment of a special class of these modes that support spectral singularities.

Customer Experience: Heterogeneity Insights From Meta‐Analytic Synthesis
Psychology &Marketing, Volume 43, Issue 6, Page 1488-1506, June 2026.ABSTRACT Overlooking heterogeneity (variability) in customer experience (CX) can lead to incomplete theoretical insights and suboptimal managerial decisions. To address this issue, this article reviews the causes of heterogeneity in extant meta‐analyses of CX research (n: 91).

TE/TM-Pass Polarizer Based on Lithium Niobate on Insulator Ridge Waveguide
IEEE Photonics Journal, 2013 We propose a TE/TM-pass polarizer based on a shallow X-cut lithium niobate-on-insulator (LNOI) ridge waveguide. In shallow X-cut LNOI ridge waveguides, the leaky mode is interchanged between TE and TM polarization waves depending on the ridge waveguide ...

Waveguiding power of photonic crystal slabs [PDF]
, 2007 We consider the waveguiding by thin patterned slabs embedded in a homogeneous medium. In the longwave limit, the wave spectra of slabs are found to be well described by a single frequency-independent parameter, which we call the "guiding power".

Bound States in the Continuum and Fano Resonances in the Dirac Cone Spectrum
, 2019 We consider light scattering by two dimensional arrays of high-index dielectric spheres arranged into the triangular lattice. It is demonstrated that in the case a triple degeneracy of resonant leaky modes in the Gamma-point the scattering spectra ...

Suppression of Anderson localization of light and Brewster anomalies in disordered superlattices containing a dispersive metamaterial [PDF]
, 2010 Light propagation through 1D disordered structures composed of alternating layers, with random thicknesses, of air and a dispersive metamaterial is theoretically investigated. Both normal and oblique incidences are considered.

Color Routing and Beam Steering of Single‐Molecule Emission with a Spherical Silicon Nanoantenna
Advanced Functional Materials, Volume 36, Issue 38, 11 May 2026.We experimentally demonstrate broadband directional emission from single molecules using a single spherical silicon nanoparticle assembled via DNA origami. By varying nanoparticle (NP) size and emitter position, we achieve unidirectional emission, beam steering, and color routing at the nanoscale, revealing modal interference as the underlying ...
