Evaluation of multi‐user multiple‐input multiple‐output digital beamforming algorithms in B5G/6G low Earth orbit satellite systems

open access: yesInternational Journal of Satellite Communications and Networking, Volume 44, Issue 1, Page 17-33, January/February 2026.
In this paper, we investigate the application of signal‐to‐leakage‐plus‐noise ratio (SLNR) beamforming to low Earth orbit non‐terrestrial networks. The SLNR criterion aims at maximizing the received desired signal power for each user while minimizing the overall interference power caused by each user to all other co‐channel receivers. We show that such

Design of Stimuli‐Responsive Cobalt Tetraphenylporphyrinate‐Chitosan Microspheres for Advanced Biosensors

open access: yesEuropean Journal of Inorganic Chemistry, Volume 29, Issue 3, January 21, 2026.
We report on new cobalt tetraphenylporphyrinate‐chitosan‐based microspheres developed for biosensing and anticancer therapy applications. We analyzed their second‐harmonic generation (SHG) behavior using a high‐resolution SHG microscope. In addition to the typical porphyrinate fluorescence, the microspheres exhibit a high‐intensity SHG response and ...

Complete NLO corrections to W+W+ scattering and its irreducible background at the LHC

open access: yesJournal of High Energy Physics, 2017
The process pp → μ +ν μ e+νejj receives several contributions of different orders in the strong and electroweak coupling constants. Using appropriate event selections, this process is dominated by vector-boson scattering (VBS) and has recently been ...

The four-dimensional helicity scheme and dimensional reconstruction

open access: yes, 2011
The four-dimensional helicity regularization scheme is often used in one-loop QCD computations. It was recently argued in Ref. [1] that this scheme is inconsistent beyond the one-loop order in perturbation theory. In this paper, we clarify the reason for

NLO QCD+EW predictions for 2ℓ2ν diboson signatures at the LHC

open access: yesJournal of High Energy Physics, 2017
We present next-to-leading order (NLO) calculations including QCD and electroweak (EW) corrections for 2ℓ2ν diboson signatures with two opposite-charge leptons and two neutrinos. Specifically, we study the processes pp→e+μ−νeν¯μ $$ pp\to {e}^{+}{\mu}^{-}{

Non-perturbative Heavy Quark Effective Theory: Introduction and Status

open access: yes, 2015
We give an introduction to Heavy Quark Effective Theory (HQET). Our emphasis is on its formulation non-perturbative in the strong coupling, including the non-perturbative determination of the parameters in the HQET Lagrangian.

Next-to-leading-order electroweak corrections to the production of three charged leptons plus missing energy at the LHC

open access: yesJournal of High Energy Physics, 2017
The production of a neutral and a charged vector boson with subsequent decays into three charged leptons and a neutrino is a very important process for precision tests of the Standard Model of elementary particles and in searches for anomalous triple ...

Automated computation of scattering amplitudes

open access: yes, 2013
We review some of the recent advances in the computation of one-loop scattering amplitudes which led to the construction of efficient and automated computational tools for NLO predictions.
