This paper presents a link adaptive processor to perform low-complexity channel estimation and QR decomposition (QRD) in Long Term Evolution-Advanced (LTE-A) receivers. The processor utilizes frequency domain correlation of the propagation channel to adaptively avoid unnecessary computations in the received signal processing, achieving significant complexity reduction with negligible performance l

Much as the contemporary understanding of world trade is often based on simple models where two countries engage in trade, so is world trade in fuel commodities typically conceived as consisting of either net-importing or net-exporting countries. However, by paying attention to the structure of world trade, represented by actually occurring trade flows between the actors in such networks, it becom

As the knowledge about anthropogenic impacts of climate change has grown, the awareness of the contributions from treatment of wastewater has widened the scope for wastewater treatment plants (WWTPs). Not only shall ever stricter effluent constraints be met, but also energy efficiency be increased, greenhouse gases mitigated and resources recovered. All under a constant pressure on costs. The main

BACKGROUND: The aim of radiotherapy is to provide a cure and/or symptomatic relief for children with cancer. Treatment is delivered on a daily basis, 5 days per week, over the course of 5 to 35 days. Many parents find that leaving their children alone during treatment and exposing them to radiation is a challenging experience. To gain an understanding of parents' lived experiences, 10 parents were

To achieve optimal virologic suppression for children undergoing antiretroviral therapy (ART), adherence must be excellent. This is defined as taking more than 95% of their prescribed doses. To our knowledge, no study in Ethiopia has evaluated the level of treatment adherence at the beginning of the child's treatment. Our aim was therefore to evaluate caregiver-reported ART non-adherence among chi

Staphylococcus aureus (S. aureus) is a notorious opportunistic foodborne pathogen and also a common cause of bovine mastitis. It is known to produce many different virulence factors, including various staphylococcal enterotoxins and toxic shock syndrome toxin-1 (TSST-1). The aim of this work was to investigate the regulation, expression, formation and role of S. aureus toxins in relation to food s

BACKGROUND: Guidelines recommend estimation of glomerular filtration rate (eGFR) prior to iodine contrast media (CM) examinations. It is also recommended that absolute eGFR in mL/min, not commonly used relative GFR (adjusted to body surface area; mL/min/1.73 m(2)), should be preferred when dosing and evaluating toxicity of renally excreted drugs.PURPOSE: To validate the absolute Lund-Malmö equatio

Cystatin C is produced in all nucleated cells. It has various functions and biological activities. Researchers are focused on its role in kidney diseases as a marker of glomerular filtration but also as a very important link in development of amyloid diseases. This work describes expression and purification of both wild type (wt) and stabilized form (stab 1 and 2) of wt cystatin C and amyloid-form

The (1)H NMR Fast Field Cycling relaxometry was applied to study the molecular dynamics of the human protein HC (alpha (1)-microglobulin), its hydration and aggregation in solution state. The (1)H NMRD data have revealed the complex nature of the water/protein HC system resulting from the co-existence of monomer and dimer forms of the protein in solution as well as the presence of oligosaccharides

Nettoprimärproduktionen (NPP), är källan till den mat vi äter, virket vi bygger hus av och veden vi eldar med. NPP spelar också en stor roll i den globala kolcykeln, genom fotosyntesen så binder växterna koldioxid från luften och producerar blad och stammar. Hur mycket växterna producerar styrs till stor utsträckning av klimatet samt hur mycket koldioxid som finns i atmosfären. Detta gör att de föNet primary production (NPP) serves as an indicator for plant-based resources such as food, timber and biofuel for human appropriation. It is defined by the annual production of plant matter and is mainly controlled by climate and human activities. Climate change in combination with human activities is altering NPP. As the controls of NPP are expected to further change in the future, it is vital t

In 1984, Richard Ruiz set forth three orientations to language planning: language as problem, language as right, and language as resource. Since that time, the orientations have only become more powerful, rising to the level of paradigm in the field of language policy and planning (LPP). In this paper, we revisit Ruiz’s orientations. By drawing upon Ruiz’s own work as well as the work of other sch
