We introduce a new method to mitigate numerical diffusion in adaptive mesh refinement (AMR) simulations of cosmological galaxy formation, and study its impact on a simulated dwarf galaxy as part of the 'EDGE' project. The target galaxy has a maximum circular velocity of 21 km s-1 but evolves in a region that is moving at up to 90 km s-1 relative to the hydrodynamic grid. In the absence of any miti
We know that planetary systems are just as common around white dwarfs as around main-sequence stars. However, self-consistently linking a planetary system across these two phases of stellar evolution through the violent giant branch poses computational challenges, and previous studies restricted architectures to equal-mass planets. Here, we remove this constraint and perform over 450 numerical int
Nontypeable Haemophilus influenzae (NTHi) is a commensal microbe often isolated from the upper and lower respiratory tract. This bacterial species can cause sinusitis, acute otitis media in preschool children, exacerbations in patients suffering from chronic obstructive pulmonary disease, as well as conjunctivitis and bacteremia. Since the introduction of a vaccine against H. influenzae serotype b
Understanding implications on firm performance from the emergence of Internet of Things (IoT) is critical in order for firms to make rational decisions regarding business model configurations and investments in IoT. The transition between the current state and widespread adoption and diffusion of IoT is expected to be complex, and standardization is one of multiple barriers discussed in research r
Flexible multibody dynamics (FMD) has found many applications in control, analysis and design of mechanical systems. FMD together with the theory of structural optimization can be used for designing multibody systems with bodies which are lighter, but stronger. Topology optimization of static structures is an active research topic in structural mechanics. However, the extension to the dynamic case
Joseph Beuys. Fat and felt. A critical essay. The extremely singular materials fat and felt for use in art, have an entirely dominating role in a long series of Joseph Beuys’ (1921-1986) most important work. They are found both in single works of art as well as in installations and happenings from the beginning of the 1960s and up to the end of the artist’s life. This essay deals with the artist’
Detecting and sorting spikes in extracellular neural recordings are common procedures in assessing the activity of individual neurons. In chronic recordings, passive electrode movements introduce changes in the shape of detected spike waveforms, and may thus lead to problems with identification and tracking of spikes recorded at separate instances in time, which is an important step in long-term m
Vid den nordiska konferensen ”Teaching bioethics” illustrerade transplantationskirurgen Nils H. Persson och jag hur en dialogpedagogisk metod kan belysa en frågeställning på ett sätt som är svårt för en ensam lärare. Nils H. Persson diskuterade bland annat den stora skillnaden i frekvens av organdonationer mellan de nordiska länderna, mindre än 15 PMP (per million population), och Spanien, mer än
In order to increase reuse, a number of product versions may be)", developed based on the same software platform. The platform must, however, be managed and updated according to new requirements if it should be reusable in a series of releases. This means that the platform is constantly changed during its lifecycle, and changes can result in degradation of the platform. In this paper, a measuremen
In FDCP2 myeloid cells, IL-4 activated cyclic nucleotide phosphodiesterases PDE3 and PDE4, whereas IL-3, granulocyte-macrophage CSF (GM-CSF), and phorbol ester (PMA) selectively activated PDE4. IL-4 (not IL-3 or GM-CSF) induced tyrosine phosphorylation of insulin-receptor substrate-2 (IRS-2) and its association with phosphatidylinositol 3-kinase (PI3-K). TNF-alpha, AG-490 (Janus kinase inhibitor),
In this paper we introduce two new methods for solving binary quadratic problems. While spectral relaxation methods have been the workhorse subroutine for a wide variety of computer vision problems - segmentation, clustering, image restoration to name a few - it has recently been challenged by semidefinite programming (SDP) relaxations. In fact, it can be shown that SDP relaxations produce better
Rodent models have been developed to study the pathogenesis of diseases caused by Helicobacter pylori, as well as by other gastric and intestinal Helicobacter spp., but some murine enteric Helicobacter spp. cause hepatobiliary and intestinal tract diseases in specific inbred strains of laboratory mice. To identify these murine Helicobacter spp., we developed an assay based on PCR-denaturing gradie
A common theme in sociological literature on "domestic violence" is that police officers view such cases as private problems and not as objects for proper policework. Thus, it is argued that police officers interactionally discourage arrest in domestic disturbance cases. In an etnographic study of Swedish police officers, however, police officers, instead of discouraging arrest or filing of compl
The aims of this study have been focused on the identification of cell surface structures involved in the induction and regulation of apoptosis. Monoclonal antibodies against the major histocompatibility complex class I (MHC-I) were shown to induce apoptosis when cross-linked on the cell surface of different malignant cells having a pre-B or a myeloid precursor phenotype. The apoptotic response wa
