The use of wood as load-bearing material in residential and office buildings has increased significantly in Europe over the last decades. Such buildings often have wooden floors built with boards supported by joists and/or beams. The modal properties of such floors are important regarding the floors’ dynamic response to walking and other usage as well as structure-borne vibration and re-radiated n

Massive multiple-input multiple-output (MIMO) promises significantly higher performance relative to conventional multiuser systems. However, the promised gains of massive MIMO systems rely heavily on the accuracy of the absolute front-end calibration, as well as quality of channel estimates at the base station (BS). In this paper, we analyze user equipment-aided calibration mechanism to estimate t

This paper proposes a pragmatic methodology to characterize mutual coupling in uniform linear arrays (ULAs). The classical coupling model used in the literature of multiple input multiple output (MIMO) antenna arrays is based on impedance parameters, resulting valid only for electromagnetically small antennas, e.g. short dipole. To test the robustness and accuracy of the proposed coupling model we

Uric acid is the end product of dietary and endogenous purine metabolism in humans and higher primates. In all lower mammalian species it is converted to allantoin by liver uricase. The aim of this study was to investigate the uric acid turnover in pig model after nephrectomy surgery, fructose-enriched diet and potassium oxonate application. The first experiment was performed using 4 intact contro

The Green Revolution in Asia from the early 1960s is defined as a process driven by governments in pursuit of self-sufficiency in food grains. The process was market-mediated and smallholder based and can be dated to the early 1960s with the Nobel Prize Laureate, Norman Borlaug’s research on high-yielding dwarf wheat in Mexico and later spread to rice and number of countries in South East and Sout

Graphene nanoribbons (GNR) constitute a rapidly growing class of novel fascinating materials. Controlling the properties of GNR often implies controlling their atomic structure. In order to exert this control, a bottom-up approach for the growth of GNR is commonly used. Despite its great success, a lack of mechanistic understanding of the on-surface chemical processes remains one of the main chall

The annual Winter School of the Danish Diabetes Academy (DDA) in November 2019 challenged postdoctoral researchers with tough questions regarding research culture that scientists around the world are discussing. The complexity and competitiveness of modern research makes it increasingly difficult for junior researchers to navigate in the science community. This editorial reflects the voices of nea

The ATLAS Open Data project is a collection of high-level data from the Large Hadron Collider and tools to analyze this data. The ATLAS Open Data can be used for education, training, outreach and citizen science. These resources are meant to be platform-independent, and are available on the web and on storage devices such as USB drives.

Two recent outreach projects are making use of public communities to enhance and build upon the first phases set up by physicists. “ATLAScraft” is a recreation of ATLAS and the wider CERN complex in Minecraft. The basic layout was provided, but school students subsequently researched and created the experiment and subdetector models and their own mini-games to explain various aspects of the LHC an

There is currently an imbalance with regards to the way that risks are treated in construction projects. Risks associated with structural failures as well as construction safety risks are often in focus while building performance risks (e.g. related to moisture or energy performance) receive less attention. These types of risks often disproportionately affect the end users/owners and can in many c

Carcinogen-DNA adducts result from the covalent interaction of electrophilic chemical carcinogens with nucleophilic sites in DNA. Some highly reactive genotoxic carcinogens are capable of directly binding to DNA but most carcinogens require metabolic activation. DNA adducts, if not repaired, can lead to mutations, and mutations in critical genes are a characteristic feature of tumors. Thus DNA add

The Swedish system has features both of civil law and of common law. Thus precedents play a more important role than they do in a dear-cut civil law or code system. Sweden has courts of first instance, six courts of appeal and a Supreme Court. Since Sweden is not a federal state, it ha.s - apart from administrative courts and the like - only one court organization. We shall discuss mainly the prac

The recent development of ultrafast extreme ultraviolet (XUV) coherent light sources bears great potential for a better understanding of the structure and dynamics of matter. Promising routes are advanced coherent control and nonlinear spectroscopy schemes in the XUV energy range, yielding unprecedented spatial and temporal resolution. However, their implementation has been hampered by the experim

Hypothesis: Previous works have shown that many-body interactions induced by dispersants with increasing correlation length will generate a diminishing two-phase region [Soft Matter 14, 6921 (2018)]. We conjecture that the attenuation of the depletion attraction due to many-body interactions is a ubiquitous phenomenon in medium-induced interactions. We propose mixtures of colloidal particles and r

This study assesses the effect of some extended Enterprise Resource Planning (ERP) capabilities (Collaboration, Analytics, Web-portals, Add-ons) and ERP use on ERP value. The research conducted, followed a mixed-methods approach using an exploratory study (Delphi) and the resource-based view of the firm to understand the ERP capabilities and develop three competing models surrounding these capabil

Background: Growing evidence suggests that pesticide exposure may influence respiratory health, but data in young children are very limited. We examined the association of prenatal pesticide exposure with lower respiratory tract infections (LRTIs) and wheeze at one year of age in children from the Infants' Environmental Health (ISA) study in Costa Rica. Methods: We measured seven pesticide metabol
