Wide-band solar radio spectral monitoring in the Phase II of Chinese Meridian Project
To achieve full-band observation of solar radio emissions, the sun-planetary interstellar monitoring chain subsystem of the Phase II of Chinese Meridian Project will construct four sets of solar radio spectrometers covering the decimeter, meter ...

Frequency–Distance Structure of Solar Radio Sources Observed by LOFAR
Low-frequency radio observations make it possible to study the solar corona at distances up to 2–3 R☉. Frequency of plasma emission is a proxy for electron density of the emitting plasma and, therefore, observations of solar radio bursts can be used to ...

Fine Structures of Solar Radio Type III Bursts and Their Possible Relationship with Coronal Density Turbulence [PDF]
Solar radio type III bursts are believed to be the most sensitive signatures of near-relativistic electron beam propagation in the corona. A solar radio type IIIb-III pair burst with fine frequency structures, observed by the Low Frequency Array (LOFAR ...

Solar Decimetre Radio Bursts [PDF]
High resolution studies (2' of arc beam) were made with the east·west arm of the Christiansen radio interferometer for about 50 21·cm solar burst events during 1958-1961. The burst sources were always closely associated in position with already existing radio plage regions of the Sun's slowly varying decimetre radiation.

On midrange periodicities in solar radio flux and sunspot areas [PDF]
Using the Hilbert-Huang transform technique, we investigate the midrange periodicities in solar radio flux at 2800 MHz (F10.7) and sunspot areas (SAs) from February 1, 1947 to September 30, 2016.

EFFECT OF SOLAR ECLIPSES ON RADIOWAVE PROPAGATION IN THE TROPOSPHERE [PDF]
Energy of solar eclipses significantly influences the variation of geophysical fields and leads to a change of processes in the subsystems of the Earth and to disturbance of the existing interactions between them. Observations of each solar eclipse allow

Adaptable Tile‐Based Pneumatic Origami through Structurally Coupled Localized Actuation
This article presents tile‐based pneumatic origami structures with rigid tiles and flexible fabric creases, achieving adaptable properties including morphing shape, selective multistability, and tunable stiffness. Independently pressurized folding bladders at each crease enable structurally coupled localized actuation of origami structures.

The paper is controversial since it is based on assumptions that require serious experimental con-firmation. An attempt has been made to relate an in-crease in the coronal mass ejection (CME) velocity at the initial stage of its motion with a decrease in

PBTTT‐OR‐R, a C14‐alkoxy/alkyl‐PBTTT polymer derivative, is of substantial interest for optoelectronics due to its specific fullerene intercalation behavior and enhanced charge‐transfer absorption. Comparing this polymer with (S) and without (O) homocoupling defects reveals that PBTTT‐OR‐R(O) forms stable co‐crystals with PC61BM, while PBTTT‐OR‐R(S ...
