An Efficient VLSI Architecture of QPP Interleaver/deinterleaver for LTE Turbo Coding

Abstract: Long Term Evolution (LTE) supports peak data rates in excess of 300 Mb/s. A good approach to achieve such rates is by parallelizing the required processing in turbo decoders. An interleaver is an important part of a turbo decoder. LTE uses the Quadratic Permutation Polynomial (QPP) interleaver, which makes it suitable for parallel decoding. In this paper, we propose an efficient architec

Österrikes Hohe Tauern

Hohe Tauern i Österrike är en av Europas vackrastenationalparker. I det artrika alplandskapet finnsbåde helt skyddade områden och zoner där bl.a.boskapsskötsel och bergsbruk tillåts.

The same or different : A comparison of the rhythmic structure of Swedish and Albanian

The purpose of this contribution is to give an account of the similarities or dissimilarities of the speech rhythm of Swedish and Albanian. In this study, temporal features were focused on to ascertain rhythmic differences between the two languages. The interest for this study arose when a clear rhythmic variation was observed in the accented Swedish L2 speech produced by L1-speakers of Albanian,

Photoreception in Phytoplankton

In many species of phytoplankton, simple photoreceptors monitor ambient lighting. Photoreceptors provide a number of selective advantages including the ability to assess the time of day for circadian rhythms, seasonal changes, and the detection of excessive light intensities and harmful UV light. Photoreceptors also serve as depth gauges in the water column for behaviors such as diurnal vertical m

RIFM fragrance ingredient safety assessment, ethylene brassylate, CAS Registry Number 105-95-3

Summary: The use of this material under current conditions is supported by existing information. This material was evaluated for genotoxicity, repeated dose toxicity, developmental and reproductive toxicity, local respiratory toxicity, phototoxicity/photoallergenicity, skin sensitization, as well as environmental safety. Data show that this material is not genotoxic nor does it have skin sensitiza

WEEE with Value: Experience from Lighting Products

• WEEE with value has traditionally been considered by simple cost -benefit analysis or models, while the reality is more complex.• Lighting products demonstrate that value can also arise from moreholistic considerations of value, and is influenced by multiple stakeholders,time considerations, and market conditions.• Mapping value can help incentivise and plan for value in rapidlychanging products

Chimney sweeps in Sweden : a questionnaire-based assessment of long-term changes in work conditions, and current eye and airway symptoms

Objectives: To explore chimney sweeping work tasks, chimney sweeps’ use of protective equipment, and type of fuel used by clients, over time. Further, to assess work-relatedness of current eye and airway symptoms. Methods: In a cross-sectional study in 2011, male Swedish chimney sweeps (n = 483; age 21–69 years) answered a questionnaire about their occupational history and eye and airway symptoms.

mTORC1 inhibition is required for sensitivity to PI3K p110α inhibitors in PIK3CA-mutant breast cancer

Activating mutations of the PIK3CA gene occur frequently in breast cancer, and inhibitors that are specific for phosphatidylinositol 3-kinase (PI3K) p110α, such as BYL719, are being investigated in clinical trials. In a search for correlates of sensitivity to p110α inhibition among PIK3CA-mutant breast cancer cell lines, we observed that sensitivity to BYL719 (as assessed by cell proliferation) wa

Attachment to mother and father at transition to middle childhood. Journal of Child and Family Studies.

The present study investigated concordance between representations of attachment to mother and attachment to father, and convergence between two narrative-based methods addressing these representations in middle childhood: the Manchester Child Attachment Story Task (MCAST) and the Secure Base Script Test (SBST). One hundred and twenty 6-year-old children were assessed by separate administrations o

Use and productivity of contemporary, multidisciplinary Big Science

The use of very large instrumentation, usually called Big Science, became an important part of Western science systems after World War II, with nuclear and particle physics at the center. Throughout the Cold War era, however, science policy priorities and objectives gradually shifted and in parallel therewith, new uses of Big Science emerged that were oriented to the study of materials and later a

Distribution of monoaminergic neurons in the nervous system of non-Malacostracan crustaceans

A comparative investigation of the distribution of monoaminergic neurons in non-malacostracan crustaceans was performed with the histochemical fluorescence method of Falck-Hillarp.Two fluorophores were found: the more widespread of the two emits a green fluorescence; and the more sparsely distributed emits a yellow to brown-yellow fluorescence.Specific green fluorescent areas were shown to exist i

The ultrastructure of a chemoreceptor organ in the head of copepod crustaceans

The ultrastructure of the paired nerves, previously called frontal organ or X-organ, in copepod crustaceans was investigated. These nerves, run- ning from the anterior margin of the brain to the frontal edge of the animals, are found to contain the dendrites of three types of morpho- logically different sensory neurons. The first unit consists of two dendrites (distinguished by their myelinization

The larvae of Pasiphaea multidentata (Esmark) and Pasiphaea tarda (Kröyer).

Pasiphaeid larvae collected in the Korsfjord, western Norway, were found to split up into two groups. Mainly two characteristics separated the larvae viz. the size of the larvae and the number of telson spines. The group with small larvae (8 to 10 mm) and the larger number of telson spines is referred to Pasiphaea multidentata and that with large larvae (10 to 12 mm) and fewer telson spines to Pas

Tailored perioperative antimicrobial prophylaxis in urological surgery : myth or reality?

PURPOSE OF THE REVIEW: The controversies surrounding perioperative antimicrobial prophylaxis (AMP) are about the use and especially misuse of antibiotics. The overall lack of evidence to facilitate a rational perioperative AMP policy in urological surgery and the postoperative infectious complications remain a challenge. Therefore, a basic tool to aid decision-making would be useful. A model based
