SIC based RL for massive MIMO NOMA signal detection for different modulation schemes under diverse channel conditions
In this study, we used Matlab-2016 to estimate the performance of the proposed SIC-RL and conventional signal detectors with a Rayleigh channel. The parameters used in this study are listed in Table 3. The selected parameters ensure an accurate…

A complexity transition in displaced Gaussian Boson sampling
D-GBS and the matching polynomial
The D-GBS problem can be visualised as the sampling of subgraphs from a graph representation of the Gaussian state, as shown in Fig. 1. Compared to regular non-displaced GBS, the addition of displacement…

Metastability and Ostwald step rule in the crystallisation of diamond and graphite from molten carbon
Phase diagram and spontaneous crystallisation
We first discuss the phase diagram of carbon in the region of the GDL triple point (Fig. 1a). Experimentally, the triple point was initially determined at T = 4100 ± 200 K, and…

Cavity-mediated collective emission from steady-state subradiance
Figure 1a–c compares two two-level emitters with different photonic environments under continuous incoherent excitation. For uncoupled emitters whose distance is much larger than their wavelength (\(d \; \gg \; \lambda\)) in free space, the…

Control strategy evaluation for reactive power management in grid-connected photovoltaic systems under varying solar conditions
Solar systems are connected to the grid through inverters, which convert DC power generated by the PV panels into AC power suitable for the grid and the aim of improving the sustainability of these types of developments. Modern inverters can also…

Radiation exposure reduction in peripheral interventions using digital variance angiography versus conventional angiography
DVA exhibits promising prospects with respect to radiation exposure and ICM in DSA. This study aimed to determine the reduction of radiation dose in EPI using series of individual image acquisitions of DSA and DUA acquisitions instead of the…

Emergence of sliding ferroelectricity in naturally parallel-stacked multilayer ReSe2 semiconductor
ReSe2 is a high ambient stable van der Waals material where each layer is composed of a Re atoms plane sandwiched between two Se atoms planes27. Different from the most common group-VI transition metal dichalcogenides (e.g., MoS2 and WS2), there…

Quantum computation via Floquet tailored Rydberg interactions
Model and Hamiltonian
As illustrated in Fig. 1, we consider a scenario involving two neutral atoms interacting via RRI. Each atom is stimulated from the hyperfine ground state \(\left\vert 1\right\rangle\) to the Rydberg excited state \(\left\vert…
