Association of Synovial Innate Immune Exhaustion With Worse Pain in Knee Osteoarthritis
Arthritis &Rheumatology, EarlyView.Objective Uncontrolled pain remains a major clinical challenge in the management of knee osteoarthritis (OA), the most common disabling joint disease. Worse pain is associated with synovial innate immune cell infiltration (synovitis), but the role of innate immune‐regulatory cells in pain is unknown. Our objective was to identify synovial innate immune

Automatic flower detection and phenology monitoring using time‐lapse cameras and deep learning
Remote Sensing in Ecology and Conservation, Volume 8, Issue 6, Page 765-777, December 2022., 2022 We present an automatized method for monitoring flower phenology of specific plant species trough full growing seasons and across geographical regions. The method couples image‐based monitoring of field plots with a dedicated convolutional neural network to detect and count flowers in the images, and returns information on flowering phenology at ...

Low Luminosity Companions to White Dwarfs [PDF]
, 2005 This paper presents results of a near-infrared imaging survey for low mass stellar and substellar companions to white dwarfs. A wide field proper motion survey of 261 white dwarfs was capable of directly detecting companions at orbital separations between $\sim100$ and 5000 AU with masses as low as 0.05 $M_{\odot}$, while a deep near field search of 86

Stellar Physics and General Relativity
Astronomische Nachrichten, EarlyView.ABSTRACT The general theory of relativity is currently established as the most precise theory of gravity supported by observations, and its application is diverse ranging from astronomy to cosmology, while its application to astrophysics has been restricted only to compact stars due to the assumption that the Newtonian approximation is sufficient for ...

Measuring the Mass–Radius Relation of White Dwarfs Using Wide Binaries
The Astrophysical JournalMeasuring the mass–radius relation of individual white dwarfs is an empirically challenging task that has been performed for only a few dozen stars. We measure the white dwarf mass–radius relation using the gravitational redshifts and radii of 135 white ...

Highlights of Astronomy, 1980 It has been known for a long time that white dwarfs are pulsationally unstable if nuclear burning takes place in their envelopes. Perturbation of energy generation rate promotes pulsational instability and this effect is frequently referred to as ε-mechanism.

Dark Energy From the Gravitational Wave Background With Scalar Field Dark Matter
Astronomische Nachrichten, EarlyView.ABSTRACT Recent observational results, such as those from pulsar timing arrays (PTA), suggest a low‐frequency Gravitational Wave Background (GWB) permeates our universe. This opens the possibility that gravitational waves could span a broader spectrum, potentially impacting cosmological scales.

Post-common envelope binaries from SDSS-X: The origin of low-mass white dwarfs [PDF]
, 2010 We present the first white dwarf mass distributions of a large and homogeneous sample of post-common envelope binaries (PCEBs) and wide white dwarf-main sequence binaries (WDMS) directly obtained from observations. Both distributions are statistically independent, with PCEBs showing a clear concentration of systems towards the low-mass end of the ...
