The choice of hyperparameter(s) notably affects the support recovery in LASSO-like sparse regression problems, acting as an implicit model order selection. Parameters are typically selected using cross-validation or various ad hoc approaches. These often overestimates the resulting model order, aiming to minimize the prediction error rather than maximizing the support recovery. In this work, we pr
Massive multiple-input multiple-output (MIMO) is one of the key candidates for the upcoming 5G wireless generation. It offers a multitude of advantages over traditional techniques, such as reduced latency, reduced interference among user equipments (UEs) and increased spectrum and energy efficiencies. However, to verify the theoretically promised gains in real-life, prototype systems are inevitabl
Much of the current work on third language acquisition focuses on modeling the impact from the speaker’s previous language(s). The Typological Primacy Model (Rothman, 2015), which covers holistic forward transfer at the initial state, and the L2 Status Factor (Bardel and Falk, 2012), which proposes forward transfer from a chronologically true L2, only predict effects on subsequently acquired langu
Recombinant adeno-associated viruses (AAVs) are popular in vivo gene transfer vehicles. However, vector doses needed to achieve therapeutic effect are high and some target tissues in the central nervous system remain difficult to transduce. Gene therapy trials using AAV for the treatment of neurological disorders have seldom led to demonstrated clinical efficacy. Important contributing factors are
Context: Both scientific publications and grey literature have widely been employed as sources of empirical evidence in evidence-based software engineering (EBSE). However, there is still a fierce debate about whether or not the pervasive Web content can act as an alternative means to gather evidence for EBSE. Aim: To help ourselves enter this debate, this work aims to obtain some pre-evidence of
A great deal of literature has analyzed the relationship between warfare and state capacity in late-modern and contemporary times. While there is a consensus regarding the significant impact of mass warfare on fiscal expansion during the twentieth century, the interplay between warfare and fiscal capacity in the nineteenth century remains disputed. This paper sheds light on this issue by making us
The flux during membrane filtration can be enhanced by the use of a two-phase gas–liquid flow. This has been shown to be an energy-efficient alternative to increasing the cross-flow velocity. In this work, air sparging was used to increase the flux during ultrafiltration of alkali-extracted wheat bran hemicelluloses. Batch filtration was performed in a pilot unit with a ceramic ultrafiltration mem
In order to increase the use of sustainable energy in Sweden, it is necessary to substitute fossil energy carriers with renewable counterparts. Synthetic natural gas (SNG) produced from renewable resources via biomass gasification and methanation could replace a proportion of the natural gas used in Sweden. In order to facilitate the implementation and expansion of SNG production and use in Sweden
This chapter discusses the Directive on Administrative Cooperation and the Recovery Directive.
This report summarizes unannounced evacuation experiments in a hotel building with evacuation elevators as one of the escape routes. The participants in the experiments were wearing an eye tracking device. The results of the experiments show that there is a high acceptance for using evacuation elevators as an escape route in the evaluated type of high-rise building. The results also show that most
This report summarizes evacuation experiments performed in a Virtual Reality environment. The experiments are performed in a subway station equipped with evacuation elevators. This study is the second step in the process of ensuring the function of new evacuation solutions. The purpose of the study is to investigate if the exit choice in the subway station can be affected by technical way-finding
A search for the exclusive decays of the Higgs and Z bosons to a ϕ or ρ meson and a photon is performed with a pp collision data sample corresponding to an integrated luminosity of up to 35.6 fb−1 collected at s=13 TeV with the ATLAS detector at the CERN Large Hadron Collider. These decays have been suggested as a probe of the Higgs boson couplings to light quarks. No significant excess of events
Inclusive J/ψ production is studied in p-Pb interactions at a centre-of-mass energy per nucleon-nucleon collision sNN=8.16 TeV, using the ALICE detector at the CERN LHC. The J/ψ meson is reconstructed, via its decay to a muon pair, in the centre-of-mass rapidity intervals 2.03 < ycms < 3.53 and −4.46 < ycms < −2.96, where positive and negative ycms refer to the p-going and Pb-going direction, resp
