Obesity-associated changes in molecular biology of primary breast cancer
Obesity is associated with an increased risk of developing breast cancer (BC) and worse prognosis in BC patients, yet its impact on BC biology remains understudied in humans. This study investigates how the biology of untreated primary BC differs according to patients’ body mass index (BMI) using data from >2,000 patients. We identify several genomic alterations that are differentially prevalent i
Production of biofuels by thermoanaerobic bacteria
Biofuel demand is gradually rising yearly and is expected to do so more rapidly due to the current energy crisis. Bioethanol production is already at a commercial scale but is primarily made using mesophiles fermenting corn and sugar, which have obvious societal drawbacks. Therefore, new technologies should be developed. In addition, hydrogen as a non-carbon energy carrier has gained renewed inter
Spatio-temporal variability of the earth’s surface temperature and the changes in land user/land cover : implications for sustainable tourism development
Tourism both contributes to environmental change and is, in turn, affected by such change. One area that is of considerable significance is tourism’s contribution to land use change and its subsequent impacts. Land use change, such as tourism urbanization, together with global heating leads to an increase in surface temperature and deterioration in environmental quality and human comfort levels. U
Determination of the strong coupling constant from transverse energy-energy correlations in multijet events at √s = 13 TeV with the ATLAS detector
Measurements of transverse energy-energy correlations and their associated azimuthal asymmetries in multijet events are presented. The analysis is performed using a data sample corresponding to 139 fb −1 of proton-proton collisions at a centre-of-mass energy of s = 13 TeV, collected with the ATLAS detector at the Large Hadron Collider. The measurements are presented in bins of the scalar sum of th
TESS and CHEOPS discover two warm sub-Neptunes transiting the bright K-dwarf HD 15906
We report the discovery of two warm sub-Neptunes transiting the bright (G = 9.5 mag) K-dwarf HD 15906 (TOI 461, TIC 4646810). This star was observed by the Transiting Exoplanet Survey Satellite (TESS) in sectors 4 and 31, revealing two small transiting planets. The inner planet, HD 15906 b, was detected with an unambiguous period but the outer planet, HD 15906 c, showed only two transits separated
Study of charged particle production at high pT using event topology in pp, p–Pb and Pb–Pb collisions at sNN=5.02 TeV
This letter reports measurements which characterize the underlying event associated with hard scatterings at mid-pseudorapidity (|η|
Deep-Learning Based High-Precision Localization with Massive MIMO
High-precision localization and machine learning (ML) are envisioned to be key technologies in future wireless systems. This paper presents an ML pipeline to solve localization tasks. It consists of multiple parallel processing chains, each trained using a different fingerprint to estimate the position of the user equipment. In this way, ensemble learning can be utilized to fuse all chains to impr
Inclusive-photon production and its dependence on photon isolation in pp collisions at √s = 13 TeV using 139 fb −1 of ATLAS data
Measurements of differential cross sections are presented for inclusive isolated-photon production in pp collisions at a centre-of-mass energy of 13 TeV provided by the LHC and using 139 fb −1 of data recorded by the ATLAS experiment. The cross sections are measured as functions of the photon transverse energy in different regions of photon pseudorapidity. The photons are required to be isolated b
A Hybrid Antenna Switching Scheme for Dynamic Channel Sounding
Channel sounding is essential for the development of radio systems. One flexible strategy is the switched-array-based channel sounding, where antenna elements are activated at different time instants to measure the channel spatial characteristics. Although its hardware complexity is decreased due to fewer radio-frequency (RF) chains, sequentially switching the antenna elements can result in aliasi
Bone mineral density loci specific to the skull portray potential pleiotropic effects on craniosynostosis
Skull bone mineral density (SK-BMD) provides a suitable trait for the discovery of key genes in bone biology, particularly to intramembranous ossification, not captured at other skeletal sites. We perform a genome-wide association meta-analysis (n ~ 43,800) of SK-BMD, identifying 59 loci, collectively explaining 12.5% of the trait variance. Association signals cluster within gene-sets involved in

High-precision cellular-based localization is one of the key technologies for next-generation communication systems. In this paper, we investigate the potential of applying machine learning (ML) to a massive multiple-input multiple-output (MIMO) system to enhance localization accuracy. We analyze a new ML-based localization pipeline that has two parallel fully connected neural networks (FCNN). The
Halide Perovskite Artificial Solids as a New Platform to Simulate Collective Phenomena in Doped Mott Insulators
The development of quantum simulators, artificial platforms where the predictions of many-body theories of correlated quantum materials can be tested in a controllable and tunable way, is one of the main challenges of condensed matter physics. Here we introduce artificial lattices made of lead halide perovskite nanocubes as a new platform to simulate and investigate the physics of correlated quant
Phylogeny, ecology and morphology of the two corticolous lichen species Rinodina colobina and R. pityrea in the Nordic countries
Rinodina pityrea and R. colobina are reported as two distinct species with differing ecology and morphological characters. Molecular analysis of their ITS and mrSSU genes show that R. pityrea and R. colobina are two clearly separated species. Furthermore, the two species are morphologically and geographically distinct in the Nordic countries and can usually be recognized with a hand lens rather th
Search for boosted diphoton resonances in the 10 to 70 GeV mass range using 138 fb −1 of 13 TeV pp collisions with the ATLAS detector
A search for diphoton resonances in the mass range between 10 and 70 GeV with the ATLAS experiment at the Large Hadron Collider (LHC) is presented. The analysis is based on pp collision data corresponding to an integrated luminosity of 138 fb −1 at a centre-of-mass energy of 13 TeV recorded from 2015 to 2018. Previous searches for diphoton resonances at the LHC have explored masses down to 65 GeV,

Why do tourists use public transport in Korea? The roles of artificial intelligence knowledge, environmental, social, and governance, and sustainability
The study of public transport and tourism, especially domestic tourism, is relatively under-researched, particularly in relation to emerging transport technologies, such as artificial intelligence (AI), and environmental, social, and governance (ESG). To bridge this gap, an integrated research model is created and tested with ESG, air quality, climate change, and AI, applying multi-analysis method

Neighbourhood deprivation and type 2 diabetes in patients with bipolar disorder : A nationwide follow-up study
Patients with bipolar disorder have higher rates of type 2 diabetes (T2D) compared to the general population. Neighbourhood deprivation is associated with T2D and bipolar disorder. The aim of this study was to explore the potential effect of neighbourhood deprivation on incident T2D in patients with bipolar disorder. This nationwide open cohort study (1997–2018) included adults in Sweden ≥20 years
