We consider the capacity of multiple-input-multiple-output (MIMO) systems with reduced complexity. One link end uses all available antennas, while the other chooses the "best" L out of N antennas. The selection of the optimum antenna subset requires an exhaustive search of all possible combinations, involving (/sub L//sup N/) computations of determinants of size L /spl times/ L, which can become p

The threatened estate - the memorials of Per Brahe junior On the background of the present research on memorials and monuments follows a study of a number of memorials erected by the count Per Brahe junior between 1653 and 1680 on Visingsö and in Skärstad in Småland, at Dimbo in Västergötland and Östra Ryd in Uppland. The memorials belong to a period, when his county Visingsborg in Sweden and baro

Many small enterprises that are planning to implement environmental management systems (EMSs) and get certified according to the ISO 14001 standard or EMAS regulation have experienced a lot of barriers on the road towards certification. The standards are perceived as bureaucratic and represent a way of working that often fits poorly into the organizational culture and decision-making structure of

Previous research indicates an uneven uptake of biologics in patients with moderate-to-severe psoriasis in Sweden. Therefore, it is essential to scrutinise variations in treatment patterns.

Capsid assembly during virus replication is a potential target for antiviral therapy. The Gag polyprotein is the main structural component of retroviral particles, and in human immunodeficiency virus type 1 (HIV-1), it contains the sequences for the matrix, capsid, nucleocapsid, and several small polypeptides. Here, we report that at a concentration of 100 M, 7 of 83 tripeptide amides from the car

An ever-increasing proportion of young males treated for cancer are cured. Therefore, one of the major challenges of modern Clinical Oncology is to ensure good quality of life. Cancer disease per se as well as cancer treatment may have a negative impact on androgen production, thereby leading to subclinical or clinically overt hypogonadism. Since the symptoms of androgen deficiency are rather unsp

OBJECTIVES: People affected by leprosy and their families face social and economic problems. The focus of interventions is often on prevention of disabilities and socioeconomic rehabilitation. The objective of this study was to explore to what extent the potential of assistive devices to facilitate activities and participation of people affected by leprosy has been utilised. DESIGN: Published lite

BACKGROUND: New experimental approaches to the study of the neutrophil phagosome and bacterial killing prompted a reassessment of the usefulness of all-trans retinoic acid (ATRA)-differentiated HL-60 cells as a neutrophil model. HL-60 cells are special in that they possess azurophilic granules while lacking the specific granules with their associated oxidase components. The resulting inability to

Syftet med denna studie var dels att samla information om den sanitära status som gäller för Mafraqs deponi och dels att bedöma lakvattnets och grundvattnets kvalitet i dess närområde. Mafraqs deponi befinner sig på en av Jordaniens viktigaste akvifer och utgör därigenom ett potentielt hot mot grundvattnets kvalitet. I området runt om deponin används grundvattnet som dricksvatten och för konstbeva
