Statistical Investigation of Wave Propagation in the Quiet-Sun Using IRIS Spectroscopic Observations
In this analysis, we use spectroscopic observations of the quiet Sun made by the IRIS instrument and investigate wave propagation. We analyze various spectral lines formed in different atmospheric layers, such as the photosphere, chromosphere, and ...

Differential emission measure of solar nanoflares measured with the SITES algorithm
The paper presents the results of a study of capabilities of the SITES algorithm for reconstructing the differential emission measure (DEM) of a source from its radiation in several parts of the electromagnetic spectrum in the context of observing solar ...

Evolutionary Tracks Of Quiet-Sun Magnetic Features
This thesis presents a study of quiet-Sun magnetic features in the solar photosphere. Magnetic fields in the quiet Sun organize on small spatial scales, evolve very rapidly, and produce weak polarization signals. With these properties their observation requires high spatial and temporal resolution together with sensitive and accurate polarimetric ...

Overabundant populations of eastern grey kangaroos Macropus giganteus in peri‐urban areas pose ecological and social challenges. Current management strategies are often hindered by animal welfare and logistical concerns. This study aimed to assess stress responses of kangaroos to two contraceptive delivery methods.

On the Existence of Long-period Decayless Oscillations in Short Active Region Loops
Decayless kink oscillations, characterized by their lack of decay in amplitude, have been detected in coronal loops of varying scales in active regions, the quiet Sun, and coronal holes. Short-period (

Estimating red deer Cervus elaphus population density using drones in a steep and rugged terrain
Precise and accurate information about population density, crucial for wildlife management, is difficult to obtain for elusive species living in dense forests or steep and inaccessible terrain. Using unmanned aerial vehicles (UAVs), we developed a method for obtaining absolute population estimates of ungulates living in steep, rugged, and partly ...

Public Inquiries and UK Press Regulation: A Case of ‘Fading into Forgetfulness’?
Abstract Why were the proposals for reform of UK press regulation made by Lord Leveson in 2012 not implemented in full, despite popular and parliamentary support for the report's recommendations, and despite the creation of the legal framework for the reformed system of regulation?

Sun Transit Outage Considering Solar Activity and It's Application to Koreasat [PDF]
The purpose of this paper is to predict Sun Transit Outage phenomenon(Sunout). Sunout had been studied mainly for the case of Geostationary satellite and under the assumption of 'Quiet Sun'.
