of the target. For a 28 MeV (p,p′) reaction on36S for instance (Fig. 3), it can be observed that describing the target nucleus within the quasiparticle random phase approximation (QRPA) framework [13,14] enables to reproduce available experimental data for inelastic scattering off the 2...
The three types of experimental error are systematic, random, and blunders. Systematic errors are errors of precision as all measurements will be off due to things such as miscalibration or background interference. Random errors occur due to happenstance, such as fluctuations in temperature or pH....
Since the advent of lasers in 1960, their extraordinary attributes—high power, efficiency, directionality, and monochromaticity—have propelled them to the forefront of scientific and technological innovation4. Many of these unique features attributed to high coherence. Nevertheless, these significant char...
In subject area: Physics and Astronomy Gamma-ray sources refer to regions in space emitting high-energy gamma radiation, often discovered through satellite missions. Some of these sources remain unidentified and can be categorized based on their location, spectral properties, and association with known...
Random numbers are necessary for many different applications, ranging from simulations to cryptography and fundamental physics tests, such as Bell tests1,2,3. Despite its common use, the certification of randomness is a complex task. Classical processes cannot generate genuine randomness because of the...
The growing integration of renewable energy sources into grid-connected microgrids has created new challenges in power generation forecasting and energy management. This paper explores the use of advanced machine learning algorithms, specifically Support
Learning process involving three ML algorithms (Extra Random Trees (XT), Gradient Boosting (GB), Extreme Gradient Boosting (XGB)) is conducted using these band centers. Cross-validation results indicated the superior accuracy of XT-model where its performance, is validated through density functional ...
