Gastrointestinal bleeding significantly increases thromboembolic risk. Higher risk was also seen in patients aged ≥ 50 years, Black patients, and those with older CF‐LVAD models. ABSTRACT Background Gastrointestinal bleeding is a common complication in continuous‐flow left ventricular assist device (CF‐LVAD) patients. Managing gastrointestinal bleeding

Shock metamorphic effects in Itokawa phosphates: A comparison with megaregolith‐derived meteorites
Abstract Returned regolith samples from the asteroid Itokawa provide a unique opportunity to compare shock metamorphic effects in unconsolidated regolith materials with those preserved in lithified meteorites, that is, megaregolith. We analyzed four Itokawa particles (Ueda—RA‐QD02‐0519, Narahara—RA‐QD02‐0573, Domon—RA‐QD02‐0588, Ishiuchi—RX‐MD03‐0212 ...

Terminal sliding mode control strategy design for second-order nonlinear system
This study mainly focuses on the terminal sliding mode control (TSMC) strategy design, including an adaptive terminal sliding mode control (ATSMC) and an exact-estimator-based terminal sliding mode control (ETSMC) for second-order nonlinear dynamical ...

Levitation Coil Length Optimization of a Magnetically Levitated Train.
AbstractAn experimental line of a magnetically levitated train (MAGLEV) using superconducting magnets (SCM) is now under construction in Yamanashi Prefecture. In the MAGLEV system, the levitation coils are mounted in the side walls. The induced current of the levitation coils generates magnetic flux that includes higher order harmonics. These harmonics

ABSTRACT The conventional ring‐spinning process has been used for over a century, being one of the most used processes in the textile industry. However, this process has some disadvantages at high spindle speeds, such as friction in the traveler/ring components that generates heat, resulting in yarn breakages or lower‐quality production.

Optimized production of a cesium Bose-Einstein condensate
We report on the optimized production of a Bose-Einstein condensate of cesium atoms using an optical trapping approach. Based on an improved trap loading and evaporation scheme we obtain more than $10^5$ atoms in the condensed phase.

Abstract Seismological observations in the lunar mantle, in conjunction with experimental knowledge on the elastic wave velocities and density of lunar mantle minerals, provide important constraints on the composition and mineralogy of the lunar mantle. Here we report elastic wave velocities and density of a lunar orthopyroxene (Mg0.84Fe0.13Ca0.03SiO3)
