Initial deployments of LTE networks are based on so-called homogeneous networks consisting of base stations providing basic coverage, called macro base stations. The concept of heterogeneous networks has recently attracted considerable attention to optimize performance particularly for unequal user or traffic distribution. Here, the layer of planned highpower macro eNBs is overlaid with layers ...

Feeding of the different developmental stages of Calanipeda aquaedulcis on natural particles (bacterio-, phytoand microzooplankton) was measured in a Mediterranean salt marsh (Empordà wetlands, NE Iberian Peninsula). Bottle incubations were performed in the field both in autumn and spring. The results showed differences in the diet of the different developmental stages due to both prey type and...

BACKGROUND Physicians are often encouraged to locate answers for their clinical queries via an evidence-based literature search approach. The methods used are often not clearly specified. Inappropriate search strategies, time constraint and contradictory information complicate evidence retrieval. AIMS Our study aimed to develop a search strategy to answer clinical queries among physicians in ...

Diffusion magnetic resonance imaging (MRI) is a technique that allows us to probe the microstructure of materials. The standard technique in diffusion MRI is diffusion tensor imaging (DTI). However, DTI can only model a single fibre orientation and fails in regions of complex microstructure. Multiple-fibre algorithms aim to overcome this limitation of DTI, but there remain many questions about ...

In the past 5 years, high brightness LEDs have begun to penetrate the lighting market. High brightness LEDs are attractive due to their high efficiency, very low power consumption and very long lifespans. This paper describes experiences in using white LEDs for lighting rural households in developing countries. The Light Up The World Foundation (LUTW) is an aid organization that has formed part...

The present article gives an overview of analytical and simulation approaches to describe the relaxation dynamics of proteins. Particularly emphasised are recent developments of theoretical models, such as fractional Brownian dynamics. The latter connects dynamical events seen on the pico- to nanosecond time scale, accessible to quasielastic neutron scattering, and functional dynamics of protei...

The mnemonic “PICO” was originally coined to help guide a standardized and disciplined way of formulating a clinical research question, carrying out a thorough literature search to answer that question (particularly through the MEDLINE/PubMed) and resultantly generate a fulfilling and all encompassing evidencebased answer to the constructed clinical query. The elements of the PICO question incl...
