Solar panel is an important structure of the spacecraft, SADA (Solar Array Drive Assembly is often used as the drive organ to realize the step-skipped gesture adjustment. Firstly, the dis turbance mechanism impact, which was produced from working SADA, to the electro-mechan ism and payload coupling has been taken into account, and the dead, rigid and flexible load S ADA disturbance model was es...

Interstellar pickup ions accelerated by the termination shock of the solar wind dominate the anomalous cosmic-ray (ACR) intensities observed by the Voyager spacecraft in the outer heliosphere. Using a twodimensional acceleration and propagation model, we derive the relative abundances of these interstellar ACRs and determine the mass dependence of the injection/acceleration efficiency for the d...

Interstellar scintillation and angular radio wave broadening measurements show that interstellar and solar wind (electron) density fluctuations exhibit a Kolmogorovlike k−5/3 power spectrum extending over many decades in wavenumber space. The ubiquity of the Kolmogorov-like interstellar medium (ISM) density spectrum led to an explanation based on coupling incompressible magnetohydrodynamic (MHD...

The interaction of the heliosphere with interstellar clouds has attracted interest since the late 1920’s, both with a view to explaining apparent quasi-periodic climate “catastrophes” as well as periodic mass extinctions. Until recently, however, models describing the solar wind local interstellar medium (LISM) interaction self-consistently had not been developed. Here, we describe the results ...

Stellar analogs for the solar wind have proven to be frustratingly difficult to detect directly. However, these stellar winds can be studied indirectly by observing the interaction regions carved out by the collisions between these winds and the interstellar medium (ISM). These interaction regions are called "astrospheres", analogous to the "heliosphere" surrounding the Sun. The heliosphere and...

IMPORTANCE The cause of follicular spicules in multiple myeloma (MM) is not known. OBSERVATIONS We present a case of follicular spicules in a patient with MM, which is very reminiscent of trichodysplasia spinulosa caused by a polyomavirus. No trichodysplasia spinulosa-associated polyomavirus could be isolated from the skin lesions; however, the spicules were positive for Merkel cell carcinoma...

Solar observations at sub-mm, mm and cm wavelengths offer a straightforward diagnostic of physical conditions in the solar atmosphere because they yield measurement brightness temperature which, for optically thick features, equals intrinsic - much unlike diagnostics other spectral ranges. The Atacama Large Millimeter sub-millimeter Array (ALMA) has therefore opened new, hitherto underexplored,...

2 Abstract We report the results of the Chandra ACIS sub-arcsecond resolution X-ray observation of the archetypal merger radio galaxy NGC 1316 (Fornax A). We confirm the presence of fine sub-structures in the hot Interstellar Medium (ISM). Some of these are likely to result from interaction with the radio jets, while others may be related to a complex intermingling of different phases of the IS...
