Extragalactic radio source evolution under the dual-population unification scheme [PDF]
, 1998 We show that a dual-population unification scheme provides a successful paradigm with which to describe the evolution and beaming of all bright extragalactic radio sources. The paradigm consists of two intrinsic radio-source populations, based on the two

Millimeter-Wave Retrodirective Wireless Power Transfer Applicable to Small Electronic Devices
IEEE Journal of MicrowavesWith the recent surge in popularity of the Internet of Things (IoT), there also has been a notable increase in research on wirelessly charging IoT enabled electronic devices. Millimeter-wave retrodirective power beaming has recently emerged as a suitable

Afterglows as Diagnostics of Gamma Ray Burst Beaming [PDF]
, 1997 If gamma ray bursts are highly collimated, radiating into only a small fraction of the sky, the energy requirements of each event may be reduced by several (up to 4 - 6) orders of magnitude, and the event rate increased correspondingly. The large Lorentz

Exact versus approximate beaming formulas in Gamma-Ray Burst afterglows [PDF]
, 2006 We present the exact analytic expressions to compute, assuming the emitted Gamma-Ray Burst (GRB) radiation is not spherically symmetric but is confined into a narrow jet, the value of the detector arrival time at which we start to "see" the sides of the ...

Pitch-angle Anisotropy Imprinted by Relativistic Magnetic Reconnection
The Astrophysical Journal, 2023 Radiation emitted by nonthermal particles accelerated during relativistic magnetic reconnection is critical for understanding the nonthermal emission in a variety of astrophysical systems, including blazar jets, black hole coronae, pulsars, and magnetars.

Relativistic Beaming and Flux Variability in Active Galactic Nuclei [PDF]
, 2001 We discuss the impact of special relativistic effects on the observed light curves and variability duty cycles of AGNs. We model the properties of AGN light curves at radio wavelengths using a simulated shot noise process in which the occurrence of major

Molecular Oncology, EarlyView.Nanosecond infrared laser (NIRL) low‐volume sampling combined with shotgun lipidomics uncovers distinct lipidome alterations in oropharyngeal squamous cell carcinoma (OPSCC) of the palatine tonsil. Several lipid species consistently differentiate tumor from healthy tissue, highlighting their potential as diagnostic markers.

Raman‐based label‐free microscopic analysis of the pancreas in living zebrafish larvae
FEBS Open Bio, EarlyView.Forward stimulated Raman scattering (F‐SRS) and epi coherent anti‐Stokes Raman scattering (E‐CARS) allow label‐free discrimination of distinct subcellular structures in the pancreas of living zebrafish larvae. Given the straightforward applicability, we anticipate broad implementation of Raman microscopy in other organs and across various biomedical ...
