The Proper Motion of Draco II with HST Using Multiple Reference Frames and Methodologies

The Astrophysical Journal
We present proper motion (PM) measurements for Draco II, an ultrafaint dwarf satellite of the Milky Way. These PMs are measured using two epochs of Hubble Space Telescope (HST)/Advanced Camera for Surveys imaging separated by a 7 yr temporal baseline ...

Realization of an Inertial Reference Frame From Mark III VLBI [PDF]

Symposium - International Astronomical Union, 1990
Over 350 000 dual frequency Mark III VLBI observations from several geodetic and astrometric observing programs have been used to realize an inertial reference frame through the positions of 325 compact extragalactic radio sources uniformly distributed over the sky with standard errors typically under 1 milliarcsecond (mas). Internal and external tests

Constancy of Speed of Light in Inertial Frames

, 2020
This article proves that speed of light in all uniformly moving inertial reference frames is absolute as postulated by Einstein. This is first done by considering light propagating with a speed c in all directions in an inertial frame of reference.

Molecular Inks for the Development of Complex 3D In‐Mold Electronics

Advanced Materials Technologies, EarlyView.
Molecular inks (MINKs) enable the fabrication of thermoformed 3D circuits by decoupling the forming and metallization steps. Following thermoforming, intense pulsed‑light or thermal processing converts the patterned MINKs into complex 3D conductive tracks with improved stretchability and electrical performance, advancing low‑cost, high‑performance in ...

Cap‐oPMN: Oral Inflammatory Load Quantification Using Capillary Microfluidics and Automated Image Processing

Advanced Materials Technologies, EarlyView.
ABSTRACT Quantifying oral polymorphonuclear neutrophils (oPMNs) is a clinically validated approach for assessing periodontal inflammation. However, current methods, such as manual hemocytometry and flow cytometry, are time‐consuming (>3 h), require invasive sampling, and depend on staining and complex instrumentation, making them unsuitable for point ...

The spatially one-dimensional relativistic Ornstein-Uhlenbeck process in an arbitrary inertial frame

, 2001
The spatially one-dimensional relativistic Ornstein-Uhlenbeck process is studied in an arbitrary inertial reference frame. In particular, we derive directly from the stochastic equations of motion in an arbitrary inertial frame the transport equation for
