BACKGROUND AND PURPOSE There is no consensus on the difference in effects of internal fixation (IF) and external fixation (EF) on outcomes for the treatment of distal radius fractures. We performed a meta-analysis of randomized clinical studies. METHODS We searched the literature and included studies that compared the effects of IF and EF on the treatment of distal radius fractures. Statistic...

The treatment of unstable Colles-type distal radial fractures remains a challenge. A prospective study was conducted to evaluate the outcomes of the treatment of unstable distal radial fractures using antegrade intra-medullary K-wires. Twenty-eight Colles-type distal radial fractures were selected excluding comminuted intra-articular and Barton's fractures. The blunt tips of intra-medullary K-w...

INTRODUCTION Although not all malunited distal radius fractures are symptomatic, the goal of treatment for displaced extra-articular fractures of the distal radius should be to restore and to maintain the radial geometry until bone healing. However, the time course change after surgery for these fractures is unclear. METHODS We, therefore, performed a retrospective cohort study on patients wh...

Due to the acceleration of black hole, circular orbits with a fixed radial coordinate and latitude for photons will deviate from equatorial plane, property hole shadow change. We find that orbit increases increasing then show observer's inclination angles, which make radius distortion maximum, increase accelerating Kerr hole.

We combine Hubble Space Telescope (HST) Fine Guidance Sensor, Hipparcos, and Gaia DR3 astrometric observations of the K0 V star 14 Her with results an analysis extensive ground-based radial velocity data to determine perturbation orbits masses for two previously known companions, b c. Radial velocities obtained Hobby-Eberly from literature now span over twenty five years. With these we obtain i...

PURPOSE We hypothesized that radial shortening osteotomy (radial shortening) for skeletally immature patients with Kienböck's disease would induce overgrowth of the radius. The purpose of this study was to determine the effect of radial shortening on radial growth in skeletally immature patients with Kienböck's disease and to clarify the relationship between the postoperative growth alterations...

Radial velocity observations of the F8 V star υ Andromedae taken at Lick and at Whipple Observatories have revealed evidence of three periodicities in the line-ofsight velocity of the star. These periodicities have been interpreted as evidence for at least three low mass companions (LMCs) revolving around υ Andromedae. The mass and orbital parameters inferred for these companions raise question...

So far, solar-like oscillations have been studied using radial velocity and/or light curve variations, which reveal frequencies of the oscillation modes. Line-profile variations, however, are also a valuable diagnostic to characterise radial and non-radial oscillations, including frequencies, amplitudes, the spherical mode wavenumbers (l,m) and the stellar inclination angle. Here we present a l...

Using black hole perturbation theory, we calculate the gravitational waves produced by test particles moving on bound geodesic orbits about rotating black holes. The orbits we consider are generic — simultaneously eccentric and inclined. The waves can be described as having radial, polar, and azimuthal “voices”, each of which can be made to dominate by varying eccentricity and inclination. Alth...

In the course of our search for double degenerate binaries as potential progenitors of type Ia supernovae with the UVES spectrograph at the ESO VLT (ESO SN Ia Progenitor surveY – SPY) we discovered that the sdB star HE 1047−0436 is radial velocity variable. The orbital period of 1.213253 d, a semi-amplitude of 94 km s −1 , and a minimum mass of the invisible companion of 0.44 M⊙ are derived fro...
