The paper describes an online deep learning algorithm for the adaptive modulation and coding in 5G Massive MIMO. The algorithm is based on a fully-connected neural network, which is initially
Review of Technologies for Ion Therapy Accelerators. (arXiv:2105.08103v1 [physics.acc-ph])
Cancer therapy using protons and heavier ions such as carbon has demonstrated advantages over other radiotherapy treatments. To bring about the next generation of clinical facilities, the requirements are likely
Single-photon imaging over 200 km. (arXiv:2103.05860v1 [eess.IV])
Long-range active imaging has widespread applications in remote sensing and target recognition. Single-photon light detection and ranging (lidar) has been shown to have high sensitivity and temporal resolution. On the
Selective orbital imaging of excited states with x-ray spectroscopy: the example of $\alpha$-MnS. (arXiv:2101.01947v1 [cond-mat.str-el])
Herein we show that non-resonant inelastic x-ray scattering involving an $s$ core level is a powerful spectroscopic method to characterize the excited states of transition metal compounds. The spherical charge
Naturally-Degradable Photonic Devices with Transient Function by Heterostructured Waxy-Sublimating and Water-Soluble Materials. (arXiv:2012.04685v1 [cond-mat.mtrl-sci])
Combined dry-wet transient materials and devices are introduced, which are based on water-dissolvable dye-doped polymers layered onto non-polar cyclic hydrocarbon sublimating substrates. Light-emitting heterostructures showing amplified spontaneous emission are used
Properties of Isoscalar Giant Multipole Resonances in medium-heavy closed-shell nuclei: a semimicroscopic description. (arXiv:2011.03315v1 [nucl-th])
The semimicroscopic particle-hole dispersive optical model (PHDOM) is implemented to describe main properties of Isoscalar Giant Multipole Resonances (up to L=3) in medium-heavy closed-shell nuclei. The main properties are characterized
The impact of modified gravity on the Sunyaev-Zel’dovich effect. (arXiv:2011.00013v1 [astro-ph.CO])
We study the effects of two popular modified gravity theories, which incorporate very different screening mechanisms, on the angular power spectra of the thermal (tSZ) and kinematic (kSZ) components of
The Evolution of Gas-Phase Metallicity and Resolved Abundances in Star-forming Galaxies at $z \approx0.6-1.8$. (arXiv:2010.15847v1 [astro-ph.GA])
We present an analysis of the chemical abundance properties of $\approx$650 star-forming galaxies at $z \approx0.6-1.8$. Using integral-field observations from the $K$-band Multi-Object Spectrograph (KMOS), we quantify the [NII]/H$\alpha$ emission-line
Historical Context, Scientific Context, and Translation of Haidinger’s (1844) Discovery of Naked-Eye Visibility of the Polarization of Light. (arXiv:2010.15252v1 [physics.hist-ph])
In 1844, the Austrian mineralogist Wilhelm von Haidinger reported he could see the polarization of light with the naked eye. It appears as a faint, blurry, transient, yellow hourglass shape
Optical spectral characterization of the the gamma-ray blazars S4 0954+65, TXS 1515-273 and RX J0812.0+0237. (arXiv:2010.14532v1 [astro-ph.HE])
The study of gamma-ray blazars is usually hindered due to the lack of information on their redshifts and on their low energy photon fields. This information is key to understand
