Near field effects are found to create systematic errors, within the range of about 5-15%, in thickness estimations from Impact-Echo (IE) testing. This paper studies near field effects from a point source in a combined Multichannel Analysis of Surface Waves (MASW) and Impact-Echo analysis. The near field creates deviations in the measured velocity of the P-wave and the Rayleigh-wave, which lead to
Considering the increasing consumption of saturated fat and glucose in diets worldwide and its possible association to carcinogenesis, this investigation analysed the proliferation profile of nonmalignant human prostate epithelial cells after exposure to elevated levels of fat and glucose. PNT1A cells were cultured with palmitate (100 or 200 μM) and/or glucose (450 mg/dl) for 24 or 48 h. Treated c
The retro-aldol reductive fragmentation of different structural types of 7-hydroxy-9,10-dioxotaxoids was investigated, showing that the reaction is typical of taxanes and requires cerium(III) promotion with NaBH4 in protic medium and alkylboron (aluminium) hydrides in aprotic solvents. The resulting 7,8-seco-taxanes are key intermediates for the synthesis of a novel class of anticancer taxanes end
Treatment of the electronically unsaturated cluster Os-3(CO)(8)(mu(3)-eta(2)-Ph2PCH2P(Ph)C6H4)(mu-H) (1) with benzothiophene in refluxing m-xylene afforded Os-3(CO)(7)(mu-PPh2)(mu-PMePh)(mu(3)-eta(2)-C6H4) (2), Os-3(CO)(7)(mu(3)-eta(2)-PPh(C6H4)CH2PPh)(mu(3)-eta(3)-SC8H5)(mu-H) (3), and Os-3(CO)(8)(mu-CO)(mu(3)-eta(2)-PPh(C6H4)CH2PPh) (4). Thermolysis of 1 in refluxing toluene for 35 h afforded on
OBJECTIVE: To evaluate the diagnostic potential of cerebrospinal fluid (CSF) levels of tau and beta-amyloid protein ending at amino acid 42 (Abeta42) as biomarkers for Alzheimer disease (AD) in clinical practice. DESIGN: A 1-year prospective study. SETTING: Community population-based sample of all consecutive patients admitted for investigation of cognitive symptoms to the Pitea River Valley Hospi
We consider propagation models that describe the spreading of an attribute, called “damage,” through the nodes of a random network. In some systems, the average fraction of nodes that remain undamaged vanishes in the large system limit, a phenomenon we refer to as exhaustive percolation. We derive scaling law exponents and exact results for the distribution of the number of undamaged nodes, valid
This thesis picks up the journey from my Bachelor’s thesis where it was concluded that current legal protection of the Intellectual Property (IP) for “computer programs” and associated components is fractured and contains gaps that provides for legal uncertainty for the author/creator/inventor. The BSc thesis’ analysis covered IP protection provided through international treaties, statutory law an

This paper presents the foundations of a transrelational theory of moral agency, which extends the relational view with the idea that moral relationships include as well as transcend the descriptive criteria – e.g., in virtue of 1st person properties or 3rd person observables – of whatever makes someone a moral agent. The result is a holistic picture that captures the complex interrelationship bet
The European spruce bark beetle is a major disturbance agent in Norway spruce forests in Europe, and with a changing climate it is predicted that damage will increase. To prevent the bark beetle population buildup, and to limit further spread during outbreaks, it is crucial to detect attacked trees early. In this study, we utilize Sentinel-2 data in combination with a risk map, created from geodat
Digitalization is shaping the discipline and practice of marketing. Not only does digitalization shape how we shop and consume everything from music to food and mobility services (Cochoy, Hagberg, McIntyre, & Sörum, 2017; Fuentes, Hagberg, & Kjellberg, 2019; Guyader, 2018; Schneider & Eli, 2022), but it has also fundamentally transformed the practices of marketing. Digitalization has c
We present a unique comparative analysis, and evaluation of vision, radio, and audio based localization algorithms. We create the first baseline for the aforementioned sensors using the recently published Lund University Vision, Radio, and Audio (LuViRA) dataset, where all the sensors are synchronized and measured in the same environment. Some of the challenges of using each specific sensor for in
The ability to perform genomic sequencing on long-dead organisms is opening new frontiers in evolutionary research. These opportunities are especially notable in the case of museum collections, from which countless documented specimens may now be suitable for genomic analysis-if data of sufficient quality can be obtained. Here, we report 25 newly sequenced genomes from museum specimens of the mode
Concerns have been raised regarding a potentially increased risk of cancer associated with treatment with glucagon-like peptide-1 (GLP-1) receptor agonists. Here, we explored whether fasting and oral glucose tolerance test post-challenge glucose-dependent insulinotropic peptide (GIP) and GLP-1 levels were associated with incident first cancer. Within the cardiovascular re-examination arm of the po

Aggressive tumours are defined by microenvironmental stress adaptation and metabolic reprogramming. Within this niche, lipid droplet accumulation has emerged as a key strategy to buffer toxic lipids and suppress ferroptosis. Lipid droplet formation can occur via de novo lipogenesis or extracellular lipid-scavenging. However, how tumour cells coordinate these processes remains poorly understood. He
Cetaceans are negatively affected by anthropogenic activities, including acoustic and physical disturbance from boat traffic. Behavioural responses to such disturbances are context-dependent, and site-specific insights are needed for effective local management plans. In this study, the impact of speed and proximity of recreational boats on the swimming speed and surfacing interval of one of the mo
