Photophysical studies of pseudo-p-distyryl[2.2]paracyclophane, a model molecule of a stilbene dimer arranged in a brick-wall geometry, in tetrahydrofurane solution indicate the existence of at least two conformers in the ground state. The conformer A with the smallest optical gap of 3 eV has a short radiative lifetime of 3.3 ns, while the conformer B with an optical gap about 0.3 eV larger is much
We present a local flow model approach for the transport and the decay of a roughly 50 year old perchloroethylene contamination at a former dry cleaning facility at Kv. Färgaren in Kristianstad that sits above the largest aquifer in Sweden. The study demonstrates an efficient workflow integrating ERT for conceptualising and calibrating a three dimensional transient, multi aquifer groundwater trans
Clinical trial results have recently demonstrated that inhibiting inflammation by targeting the interleukin-1β pathway can offer a significant reduction in lung cancer incidence and mortality, highlighting a pressing and unmet need to understand the benefits of inflammation-focused lung cancer therapies at the genetic level. While numerous genome-wide association studies (GWAS) have explored the g
BackgroundHalogenated anaesthetic agents are potent greenhouse gases, but little is known about the trajectory of their use and their greenhouse gas impact on a global level. The primary aim of this study was to estimate the global greenhouse gas impact of halogenated anaesthetic agents over the preceding 10 years.
We focus on the task of estimating a physically plausi-ble articulated human motion from monocular video. Ex-isting approaches that do not consider physics often pro-duce temporally inconsistent output with motion artifacts, while state-of-the-art physics-based approaches have either been shown to work only in controlled laboratory conditions or consider simplified body-ground contact limited to f
This book analyses and discusses the use of Islamic terms and symbols in the political party Sri Lanka Muslim Congress (SLMC). It is based on interviews with the leading members of the party and on analyses of the party’s official documents. It describes the history of Muslims in Sri Lanka, presents the analytical framework used, and discusses the official documents and narratives of party members
Most products are developed while adapting to requirements from industrial production and logistics. To break that trend and design for people, we suggest focusing on those who put the strongest demands on the final solution. They cannot compensate for bad design solutions and are thereby, like sniffing dogs, guiding designers to meet peoples’ needs. We always use a combination of empathic modelli
Huge dynamic Stark shifts of atomic energy levels in xenon induced by high-intensity laser light have been measured by a new method based upon multiphoton ionization by a tunable femtosecond laser source. Stark-induced multiphoton resonances appear as identifiable structures in the photoelectron energy spectra. The change in the structures positions, when the photon energy is tuned, is directly re
Small ligaments connecting the fracture surfaces just behind a moving crack front are assumed to exist under certain conditions. The ligaments are rapidly torn as the crack advances. Inelastic straining of such ligaments influences the energy balance in the fracture process. The rapid tearing of a single ligament is studied both numerically and experimentally. An elastic visco-plastic material mod
Pointing is a typical means of directing a human's attention to a specific object or event. Robot pointing behaviours that direct the attention of humans are critical for human-robot interaction, communication and collaboration. In this paper, we describe an experiment undertaken to investigate human comprehension of a humanoid robot's pointing behaviour. We programmed a NAO robot to point to mark
We compare terminology used in the literature on multigrid methods for compressible computational fluid dynamics to that used in linear multigrid theory. Several popular iterative and direct smoothers are presented side-by-side using the same terminology. We argue for greater analysis of these methods in order to place them into a more rigorous framework and to identify the most promising candidat
The primary aim of the present study was to determine the expression levels of cannabinoid receptor type 1 (CB1) in steatotic rat livers. The secondary aim was to clarify whether steatosis and inflammation are more marked in areas with increased CB1 overexpression. For ethical and economic reasons, the present study investigated tissue from archived liver blocks, which were obtained from 38 rats t
Jupiter's core is generally assumed to have formed beyond the snow line. Here we consider an alternative scenario that Jupiter's core may have accumulated in the innermost part of the protoplanetary disc. A growing body of research suggests that small particles ('pebbles') continually drift inward through the disc. If a fraction of drifting pebbles is trapped at the inner edge of the disc, several
We investigate the prospects for the capture of the proposed Planet 9 from other stars in the Sun's birth cluster. Any capture scenario must satisfy three conditions: the encounter must be more distant than ∼150 au to avoid perturbing the Kuiper belt; the other star must have a wide-orbit planet (a ≳ 100 au); the planet must be captured on to an appropriate orbit to sculpt the orbital distribution
In Information Gap Decision Theory (IGDT) a system is said to be robust to uncertainty if specified goals are achieved with satisfaction despite large info-gaps. Under this theory an info-gap expresses the disparity between what is known and unknown in structures for which uncertainty is judged as severe. We discuss how robustness in IGDT can be merged with a perspective on risk which allows for d
Coronavirus Disease 2019 (COVID-19) poses an enormous challenge to health care systems throughout the world, but it doesn’t affect every individual to the same extent. There is great variability in disease outcomes. Therefore, identifying the main prognostic risk factors is of paramount importance. These include increased age, skin pigmentation, obesity, pre-existing illness, and vitamin D deficie
