Magnetic order and Li-diffusion in the 1/3-filled Kagome layers of antiperovskite Lithium-ion battery materials (LiFe)SO and (LiFe)SeO
F. Seewald, T. Schulze, N. Gräßler +8
The recently discovered lithium-rich antiperovskites (LiFe)SeO and (LiFe)SO host lithium and iron ions on the same atomic position which octahedrally coordinates to central…
Hot primordial regions with anomalous hydrogenless chemical composition
K. M. Belotsky, M. M. El Kasmi, S. G. Rubin +1
We study primordial nucleosynthesis in hypothetical hot regions that could be formed by the primordial density inhomogeneities. It is shown that the regions survived up to the pres…
A Direct Integral Pseudospectral Method for Solving a Class of Infinite-Horizon Optimal Control Problems Using Gegenbauer Polynomials and Certain Parametric Maps
Kareem T. Elgindy, Hareth M. Refat
We present a novel direct integral pseudospectral (PS) method (a direct IPS method) for solving a class of continuous-time infinite-horizon optimal control problems (IHOCs). The me…
A Temporal Scale to Track the Spectral Transitions in Low-Mass X-ray Binaries
E. Sonbas, K. Mohamed, K. S. Dhuga +1
The results of a temporal analysis of observations for a sample of nine low-mass X-ray binaries (LMXBs) are presented. Of these sources, five host a neutron star (NS) primary (4U16…
A Minimal Timescale for the Continuum in 4U 1608-52 and Aql X-1
K. Mohamed, E. Sonbas, K. S. Dhuga +4
Similar to black-hole X-ray binary (BHXRB) transients, hysteresis-like state transitions are also seen in some neutron-star X-ray binaries (NSXRBs). Using a method based on wavelet…
A Pilot Study of Smart Agricultural Irrigation using Unmanned Aerial Vehicles and IoT-Based Cloud System
Mohamed Esmail Karar, Faris Alotaibi, Abdullah AL Rasheed +1
This article introduces a new mobile-based application of modern information and communication technology in agriculture based on Internet of Things (IoT), embedded systems and an…
