In the cuprate superconductors, the spatial coherence of the charge density wave (CDW) state grows below a temperature TCDW, the origin of which is debated. Using x-ray photon correlation spectroscopy, we have studied the temporal atomic relaxation dynamics in La1.88Sr0.12CuO4 to shed light on this question. Cooling within an emergent structurally distorted phase, which favors the CDW modulation i

Searches for new physics (NP) at particle colliders typically involve multivariate analysis of kinematic distributions of final state particles produced in a decay of a hypothetical NP resonance. Since the pair-production cross-sections mediated by such resonances are strongly suppressed by the NP scale, this analysis becomes less relevant for NP searches for masses of the BSM resonance above 1 Te

This article analyses infant and child sex ratios in late Imperial Russia relying on district-level information obtained from the 1897 Russian census (489 districts). The article shows that child sex ratios were, on average, relatively low (around 98 boys per hundred girls) due to the biological female advantage: the extremely high infant and child mortality rates took a greater toll on boys and p

This paper examines the economic effects of German settlers on Imperial Russia’s transition to advanced industrialization in the late nineteenth and early twentieth century. Between 1763 and 1860, thousands of German migrants came to the country’s frontier regions, drawn by a state-sponsored settlement policy. Using accidental elements in German migration induced by policy, the paper demonstrates

Cultural norms play a pivotal role in shaping how societies respond to crises. This study examines the causal effect of ethnic-specific gender norms on gender-biased mortality during resource shocks. Studying the 1891-1892 Russian famine, we compare cohorts born before and after the famine in districts differentially affected by the famine and with diverse gender norms. Our findings reveal that ar

The thesis focuses on studying dense particle flows, which are either dry or submerged in a Newtonian fluid through two dimensional numerical simulations using the discrete element method (DEM). The First paper deals with dense suspensions in viscous regime under oscillatory planar shear. We found that having an oscillatory shear can help reducing the viscosity of the suspension. Also, in the fric

This article examines the way the notion of labour regime in artisanal and small-scale mining (ASM) research can contribute to new ways of conceptualising this sector's challenges. It starts by reviewing how the phenomenal expansion of ASM over the last decades has been problematised, and highlights the need to better understand what drives artisanal miners to operate under extremely precarious wo

Articles 184 and 185 of the VAT Directive provide for the general obligation to adjust an initial deduction if it is higher or lower than that to which the taxable person was entitled. Does the abandonment of an investment project always imply the obligation to adjust deductions in respect of the acquired goods and/or services that cannot be used in the taxed activity of the taxable person? What i

High levels of ADAM17 activity have emerged as an important mediator in severe COVID-19. This study aims to characterize eventual causal relationships between ADAM17 and COVID-19. Using Mendelian randomization analyses, we examined the causal effects of circulating ADAM17 on COVID-19 outcomes using summary statistics from large, genome-wide association studies of ADAM17 (up to 35,559 individuals)

Arctic ecosystems are warming nearly 4 times faster than the global average, which is resulting in plant community shifts and subsequent changes in biogeochemical processes such as gaseous fluxes. Additionally, herbivores shape plant communities and thereby may alter the magnitude and composition of ecosystem respiration and biogenic volatile organic compound (BVOC) emissions. Here we determine th

Preventing relapse into violence and its destructive consequences among persistent re-offenders is a primary concern in forensic settings. The Risk-Need-Responsivity framework models the best current practice for offender treatment, focused on building skills and changing pro-criminal cognitions. However, treatment effects are often modest, and the forensic context can obstruct the delivery of int

This paper explores how the Helsinki process altered practices within the Swedish Pentecostal community. In order to understand this process of change, we need to take two fundamental, and slightly contradictory, traits related to the East-West conflict found among this religious grouping into account. First, post-WWII Swedish Pentecostals were in general vehemently opposed to Communism and to the

In this paper, we investigate the effects of different augmentation strategies in self-supervised representation learning from electrocardiograms. Our study examines the impact of random resized crop and time out on downstream performance. We also consider the importance of the signal length. Furthermore, instead of using two augmented copies of the sample as a positive pair, we suggest augmenting

We introduce a model description of a diatomic molecule in an optical cavity, with pump and fluorescent fields, and electron and nuclear motion are treated on equal footing and exactly. The model accounts for several optical response temporal scenarios: A Mollow spectrum hindered by electron correlations, a competition of harmonic generation and molecular dissociation, a dependence of fluorescence

Background: Primary hyperparathyroidism (PHPT) is a common endocrine disorder. Definitive treatment is surgical. Preoperative localization of diseased glands increases the chance of successful treatment. The aim of this study is to investigate the diagnostic performance of 18F-fluoromethylcholine-positron emission tomography-computed tomography (18F-FCh-PET-CT) in preoperative localization of dise

Scientific uncertainty is clearly a prominent hurdle in public health policy and the policy choices made to tackle this uncertainty are largely left to the Member States. Indeed, the Court of Justice of the EU has long since held that the health and the life of humans rank first among the interests that Member States can legitimately pursue - even if they restrict the market freedoms in doing so -

The recent interest in characterizing 2D boron polymorphs has led to claims of the first stabilization of a honeycomb phase with conical Dirac-like electron dispersion. However, the synthesis of chemically stable, single, and homogeneous 2D boron phases still represents a significant experimental challenge. This is ascribed to the intrinsic boron electronic configuration that, at variance with car
