High frequency III-V nanowire MOSFETs

III-V nanowire transistors are promising candidates for very high frequency electronics applications. The improved electrostatics originating from the gate-all-around geometry allow for more aggressive scaling as compared with planar field-effect transistors, and this can lead to device operation at very high frequencies. The very high mobility possible with In-rich devices can allow very high dev

Stone Tablets, Memorial Texts and Agency in Late-Medieval Scandinavian Castles : The Examples of Glimmingehus and Olofsborg

This paper explores how noblemen expressed themselves in late-medieval Scandinavian castles, in the buildings and in the landscape. The focus is on decorated stone tablets with coats of arms and memorial texts found on the castle walls, but the landscape setting of the castles is also discussed. The examples considered here are Glimmingehus in Scania, in present-day southern Sweden, and Olofsborg

Dysphagia - Results from multivariable predictive modelling on aspiration from a subset of the ARTSCAN trial

Purpose: To establish predictive models for late objective aspiration and late patient-reported choking based on dose-volume parameters and baseline patient and treatment characteristics, for patients with head and neck cancer undergoing definitive radiotherapy (RT). The impact of electively treated volume on late aspiration was also investigated. Methods and material: This prospective cohort is a

Integrin β1, osmosensing, and chemoresistance in mouse ehrlich carcinoma cells

Background/Aims: Altered expression of the integrin family of cell adhesion receptors has been associated with initiation, progression, and metastasis of solid tumors as well as in the development of chemoresistance. Here, we investigated the role of integrins, in particular integrin β1, in cell volume regulation and drug-induced apoptosis in adherent and non-adherent Ehrlich ascites cell lines. M

Regulation of polarized morphogenesis by protein kinase C iota in oncogenic epithelial spheroids

Protein kinase C iota (PKCι), a serine/threonine kinase required for cell polarity, proliferation and migration, is commonly up- or downregulated in cancer. PKCι is a human oncogene but whether this is related to its role in cell polarity and what repertoire of oncogenes acts in concert with PKCι is not known. We developed a panel of candidate oncogene expressing Madin-Darby canine kidney (MDCK) c

Cancer dissemination--lessons from leukocytes

Cancer cells can move through tissues in a variety of different ways. In some cases, an epithelial-to-mesenchymal transition enables cancer cells to acquire fibroblast-like migratory properties. However, it is also becoming apparent that some cancer cells move in an amoeboid way similar to leukocytes. This theme will be the focus of the review, where we will discuss the similarities and difference

Stability analysis of an artificial biomolecular oscillator with non-cooperative regulatory interactions

Oscillators are essential to fuel autonomous behaviours in molecular systems. Artificial oscillators built with programmable biological molecules such as DNA and RNA are generally easy to build and tune, and can serve as timers for biological computation and regulation. We describe a new artificial nucleic acid biochemical reaction network, and we demonstrate its capacity to exhibit oscillatory so

The larval compound eye of barnacles

The compound eye of the cypris larva of Balanus crenatus comprises about 10 ommatidia. The ommatidia possess a crystalline cone formed by three cone cells, two distal pigment cells, and six retinular cells that together form the rhabdom. The compound eye of the cypris larva of Balanus exhibits similarities to that of branchiurans and ostracodes, but the latter two groups share more common characte

Almost There : Washington Park

A surreal account of imagined venues associated with Washington Park area in Chicago. The film was produced during the course of the residency, and is based on audio and video associated with the Washington Park area in southern Chicago. Conceptually, the film takes its point of departure in City of Chicago’s bid to host the 2016 Olympic Summer Games, in which Washington Park was proposed as the m

Cold war isomorphism : communist regimes and the West European model of worker participation

In studies of cultural globalisation, the influence of communist regimes onWestern Europe has remained under-theorised and little explored. Addressingthis gap in research, this article puts forward the glocalisation grid of world-politytheory as a means for conceptualising and investigating how EastEuropean communist regimes helped shape the evolution of West Europeanwelfare states during the Cold

Physical explanation of the SLIPI technique by the large scatterer approximation of the RTE

Visualizing the interior of a turbid scattering media by means light-based methods is not a straightforward task because of multiple light scattering, which generates image blur. To overcome this issue, a technique called Structured Laser Illumination Planar Imaging (SLIPI) was developed within the field of spray imaging. The method is based on a ‘light coding’ strategy to distinguish between dire

Experimental radiative lifetimes for highly excited states and calculated oscillator strengths for lines of astrophysical interest in singly ionized cobalt (Co ii)

This work reports new experimental radiative lifetimes and calculated oscillator strengths for transitions of astrophysical interest in singly ionized cobalt. More precisely, 19 radiative lifetimes in Co+ have been measured with the time-resolved laser-induced fluorescence technique using one- and two-step excitations. Out of these, seven belonging to the high lying 3d7(4F)4d configuration in the

Well-ordered in adatoms at the In2 O3 (111) surface created by Fe deposition

Metal deposition on oxide surfaces usually results in adatoms, clusters, or islands of the deposited material, where defects in the surface often act as nucleation centers. Here an alternate configuration is reported. After the vapor deposition of Fe on the In2O3(111) surface at room temperature, ordered adatoms are observed with scanning tunneling microscopy. These are identical to the In adatoms

Long-term functional outcomes after radical cystectomy with ileal bladder substitute : does the definition of continence matter?

Objective: Functional outcomes after ileal bladder substitution reflect the expectations of future patients at a particular centre. The aim of this study was to use validated questionnaires and a pad-weighing test to investigate functional outcomes after neobladder reconstruction at long-term follow-up in patients at a single centre. Materials and methods: During 2005 − 2015, 75 patients received

Autonomy in PhD-education – Supervising for Independence

According to the Swedish higher ordinance of education the development of autonomy of PhD students is of high importance. Graduates should be able to formulate new ideas and to independently assess and evaluate scientific results. Therefore it is interesting to investigate how the relationship between student and supervisor impacts the development of autonomy. In this work, we have evaluated the i

ChPT meets lattice : Finite volume and partial quenching for masses, decay constants and VEVs at NNLO

We discuss finite volume effects and partial quenching for Chiral Perturbation Theory in the mesonic sector. The effects are computed in terms of analytical expressions for masses, decay constants and vacuum expectation values (VEVs) to two-loop order. Numerical examples are presented for a number of interesting and relevant cases. All numerical programs are publically available, the prospects of

Low or No Inhibitory Potency of the Canonical Galectin Carbohydrate-binding Site by Pectins and Galactomannans

Some complex plant-derived polysaccharides, such as modified citrus pectins and galactomannans, have been shown to have promising anti-inflammatory and anti-cancer effects. Most reports propose or claim that these effects are due to interaction of the polysaccharides with galectins because the polysaccharides contain galactose-containing side chains that might bind this class of lectin. However, t
