On cooperation in DVB-S2X receivers through a capacity constrained link

A scheme for exploiting cooperation in satellite receivers is proposed. The cooperation takes place through a capacity-constrained link, and we assume that a relay node quantizes its received signal and sends it to the destination node. We demonstrate its effectiveness with three different schemes on satellite channels with high-order APSK modulations. The first two schemes employ equidistant quan

Investigation of single and synergic effects of NLRC5 and PD-L1 variants on the risk of colorectal cancer

Constitutive activation of interferon signaling pathways has been reported in colorectal cancer (CRC), leading to a strong CD8+ T cell response through stimulation of NLRC5 expression. Primed CD8+ T cell expansion, however, may be negatively regulated by PD-L1 expression. Additionally, aberrant PD-L1 expression enables cancer cells to escape the immune attack. Our study aimed to select potential r

Aggregate Size Dependence of Amyloid Adsorption onto Charged Interfaces

Amyloid aggregates are associated with a range of human neurodegenerative disorders, and it has been shown that neurotoxicity is dependent on aggregate size. Combining molecular simulation with analytical theory, a predictive model is proposed for the adsorption of amyloid aggregates onto oppositely charged surfaces, where the interaction is governed by an interplay between electrostatic attractio

Pharmacological treatment patterns in neuropathic pain--lessons from Swedish administrative registries

OBJECTIVE: To explore the treatment patterns of patients with a diagnosis related to chronic pain (DRCP) initiating pharmacological treatment indicated for neuropathic pain (NeuP: tricyclic antidepressants, serotonin-norepinephrine reuptake inhibitors, and anticonvulsants).DESIGN: Retrospective study on administrative registers.SETTING: General population in Western Sweden (one sixth of the countr

The host defense peptide LL-37 is detected in human parotid and submandibular/sublingual saliva and expressed in glandular neutrophils

The human host defense peptide, LL-37, is an important player in the first line of defense against invading microorganisms. LL-37 and its precursor, hCAP18, have been detected in unstimulated whole saliva but no reports showing hCAP18/LL-37 in isolated, parotid, and/or submandibular/sublingual saliva have been presented. Here, we measured the levels of hCAP18/LL-37 in human parotid and submandibul

Both weight at age 20 and weight gain have an impact on sleep disturbances later in life : Results of the EpiHealth study

Study Objectives: Obesity is often associated with impaired sleep, whereas the impact of body mass index (BMI) at younger age and previous weight gain on sleep problems remains unknown. Methods: The present study utilized data from the Swedish EpiHealth cohort study. A total of 15845 participants (45–75 years) filled out an internet-based questionnaire. BMI was calculated from both measured data a

The impact of deuteration on natural and synthetic lipids : A neutron diffraction study

The structural investigation of cellular membranes requires access to model systems where the molecular complexity is representative of the cellular environment and that allow for the exploitation of structural techniques. Neutron scattering, and in particular neutron diffraction can provide unique and detailed information on the structure of lipid membranes. However, deuterated samples are desira

Making Minimal Solvers for Absolute Pose Estimation Compact and Robust

In this paper we present new techniques for constructing compact and robust minimal solvers for absolute pose estimation. We focus on the P4Pfr problem, but the methods we propose are applicable to a more general setting. Previous approaches to P4Pfr suffer from artificial degeneracies which come from their formulation and not the geometry of the original problem. In this paper we show how to avoi

Export-led innovation : The role of export destinations

This article analyzes the effect of exporting activity on the innovative performances of firms in France, Germany, Italy, Spain, and UK. It argues that the positive effect of exporting on innovation usually found in the literature varies according to the specific destinations of exports, and it identifies two dimensions along which export destinations might differ: the level of foreign technologic

Nanoscale electron tomography and compositional analysis of Aerotaxy nanowires

One common goal of sample analysis is to provide structural, compositional, or functional data in order to improve production parameters. One instrument specialized in such structural and compositional analysis with a high spatial resolution is the transmission electron microscope (TEM). The high-end microscopes have the capability of sub-Ångström resolution and compositional quantification and di

Development of a language screening instrument for Swedish 4-year-olds

Background: The Swedish Program for health surveillance of preschool children includes screening of language and communication abilities. One important language screening is carried out at age 4 years as part of a general screening conducted by health nurses at child health centres. The instruments presently in use for this screening mainly focus on expressive phonology. This may result in both ov

Composing The Performance : An exploration of musical composition as a dramaturgical strategy in contemporary intermedial theatre

This thesis explores musical composition in the context of contemporary theatre. It suggests methods where compositional thinking – broadly understood – can be used as a dramaturgical device in the creation of theatre performances. Such musicalization of theatre provides new methods for an artistic practice and questions traditional artistic hierarchies and working structures. The investigation de

Catching glimpses : the fragment-anthology as a strategy for architectural research

The weaving together of fragments under the heading of a “weak” theme has a long tradition in research. The strategy has, however, not been so popular after the 19th century, even though advocates of a more modern fragmentology can be found, e.g. in Walter Benjamin. For Benjamin, the artefacts truly showed themselves only when the context had disappeared or been forgotten. In this article we would

Experimental and Computational Atomic Spectroscopy for Astrophysics : Oscillator strengths and lifetimes for Mg I, Si I, Si II, Sc I, and Sc II

Precis efter Big Bang fanns endast tre grundämnen: väte, helium och en liten mängd litium. De första stjärnorna föddes i gasmoln som innehöll dessa ämnen. När den första generationen stjärnor i slutet av sina liv exploderade som supernovor spreds de tyngre grundämnena som tillverkats ut i det interstellära mediet. Nästa generations stjärnor bildades från detta berikade medium, och innehöll därför Atomic data such as oscillator strengths and wavelengths are important for astrophysical applications as they have a crucial role in determining abundances of specific elements in a star, a galaxy, or any object emitting radiation in the space. Stars in the Galaxy mostly keep the composition of the interstellar gas from which they were formed, therefore studying stellar abundances helps us underst

Identified Hadron Production as a Function of Event Multiplicity and Transverse Spherocity in pp Collisions at √s = 7 and 13 TeV with the ALICE Detector

Över 30 år av forskning inom tungjonsfysik, Quantum ChromoDymanics (QCD) och kosmologi har etablerat vår nuvarande syn på universums tidigare stadie: kort efter Big Bang var universum fyllt av ett mycket hett och kompakt medium bestående av fria kvarkar och gluoner, den så kallade Kvarkgluon plasman (Quark--Gluon Plasma, QGP). Detta medium expanderade snabbt, och kyldes ner tills beståndsdelarnas This study reports on identified hadron production as a function of event multiplicity (dNch/dη) and transverse spherocity (SO) in proton-proton collisions at √s = 7 and 13 TeV measured with the ALICE detector at the LHC. The particle spectra and their ratios measured in high-multiplicity events show signatures of an expanding medium. Integrated particle yields as a function of multiplicity measur

Postprandial increase in energy expenditure correlates with body weight reduction in patients with type 2 diabetes receiving diet therapy

Here we analyzed the relationships between EE and clinical measurements in patients with type 2 diabetes receiving diet therapy. Methods: A total of 100 patients (34 women and 66 men) with type 2 diabetes admitted to our hospital for glycemic control were enrolled. The parti

Characterization of pancreatic islets in two selectively bred mouse lines with different susceptibilities to high-fat diet-induced glucose intolerance

Hereditary predisposition to diet-induced type 2 diabetes has not yet been fully elucidated. We recently established 2 mouse lines with different susceptibilities (resistant and prone) to high-fat diet (HFD)-induced glucose intolerance by selective breeding (designated selectively bred diet-induced glucose intolerance-resistant [SDG-R] and -prone [SDG-P], respectively). To investigate the predispo
