A Precessing, Magnetically Dominated, Structured Jet Powering the Hour-scale Quasiperiodic GRB 250702B

The Astrophysical Journal Letters
GRB 250702B shows ultralong episodic prompt activity (three hard-gamma-ray episodes over ≃3.2 hr with quasi-regular spacing P ≃ 2825 s) preceded by a soft-X-ray flare about one day earlier.

Experimental aspects of 14N overtone RESPDOR solid-state NMR spectroscopy under MAS beyond 60 kHz

Magnetic Resonance Letters
Nitrogen-14 (14N) overtone (OT) spectroscopy under fast magic angle spinning (MAS) conditions (>60 kHz) has emerged as a powerful technique for observing correlations and distances between 14N and 1H, owing to the absence of the first-order quadrupolar ...

Space Gravity Spectroscopy - determination of the Earth’s gravitational field by means of Newton interpolated LEO ephemeris Case studies on dynamic (CHAMP Rapid Science Orbit) and kinematic orbits [PDF]

Advances in Geosciences, 2003
An algorithm for the (kinematic) orbit analysis of a Low Earth Orbiting (LEO) GPS tracked satellite to determine the spherical harmonic coefficients of the terrestrial gravitational field is presented.

Analysis on the Influence Factors of Bulk Temperature of the Meshing Gear of a Nutation Drive with a Double Circular-arc Spiral Bevel Gear

Jixie chuandong
The meshing temperature affects the fatigue, vibration, noise and other behaviors in the nutation transmission process of the double circular-arc spiral bevel gear, which cannot be ignored in the life prediction and mechanical response of the double ...
