A New Digital Front-End for Flexible Reception in Software Defined Radio

Future mobile terminals are expected to support an ever increasing number of Radio Access Technologies (RAT) concurrently. This imposes a challenge to terminal designers already today. Software Defined Radio (SDR) solutions are a compelling alternative to address this issue in the digital baseband, given its high flexibility and low Non-Recurring Engineering (NRE) cost. However, the challenge stil

Expression of Zinc Finger 23 Gene in Human Hepatocellular Carcinoma

The aim of this study was to investigate the relationship between human zinc finger 23 (ZNF23) expression and clinico-pathological characteristics in patients suffering from hepatocellular carcinoma (HCC), and to investigate ZNF23 expression in relation to cell apoptosis. Patients and Methods: Thirty-seven HCC samples were collected and ZFP23 mRNA levels were determined by real-time reverse transc

A longitudinal study of sick building syndrome among pupils in relation to microbial components in dust in schools in China

There are few longitudinal studies on sick building syndrome (SBS), which include ocular, nasal, throat, and dermal symptoms, headache, and fatigue. We studied the associations between selected microbial components, fungal DNA, furry pet allergens, and incidence and remission of SBS symptoms in schools in Taiyuan, China. The study was based on a two-year prospective analysis in pupils (N = 1143) i

An Aspergillus nidulans GH26 endo-β-mannanase with a novel degradation pattern on highly substituted galactomannans.

The activity and substrate degradation pattern of a novel Aspergillus nidulans GH26 endo-β-mannanase (AnMan26A) was investigated using two galactomannan substrates with varying amounts of galactopyranosyl residues. The AnMan26A was characterized in parallel with the GH26 endomannanase from Podospora anserina (PaMan26A) and three GH5 endomannanases from A. nidulans and Trichoderma reesei (AnMan5A,

Localization of Sunitinib in in vivo Animal and in vitro Experimental Models by MALDI Mass Spectrometry Imaging

The spatial distribution of an anti-cancer drug and its intended target within a tumor plays a major role on determining how effective the drug can be at tackling the tumor. This study provides data regarding the lateral distribution of sunitinib, an oral antiangiogenic receptor tyrosine kinase inhibitor using an in vitro animal model as well as an in vitro experimental model that involved deposit

A prospective cohort study on risk of acute pancreatitis related to serum triglycerides, cholesterol and fasting glucose

Background/objectives: To investigate risk for acute pancreatitis related to moderately elevated triglycerides, cholesterol and fasting glucose. Methods: This was a prospective cohort study in Malmo, Sweden of 33 346 subjects investigated 1974 - 1992 and followed until December 31, 2006. Baseline investigation included a self-administered questionnaire and analysis of serum triglycerides, choleste

Observing as an essential facet of mindfulness: A comparison of FFMQ patterns in meditating and non-meditating individuals.

One of the most comprehensive measures of mindfulness is the Five Facet Mindfulness Questionnaire (FFMQ) with five factors—Observing, Describing, Acting with awareness, Non-judging, and Non-reactivity. Hierarchical confirmatory factor analyses, however, have suggested that only four of the FFMQ factors (i.e. all except Observing) were components of “an overall mindfulness construct”—which is puzzl

The Genetics of Autism Spectrum Disorders and Related Neuropsychiatric Disorders in Childhood.

Objective: Autism spectrum disorders are considered to be among the most heritable mental disorders, a notion based on surprisingly sparse data from small clinical studies. Population-based studies of the heritability of other neuro-psychiatric disorders and comorbidities among them have also been sparse. The authors sought to address both of these issues. Method: Parents of all Swedish 9- and 12-

Hyperbaric oxygen therapy as adjunctive treatment of diabetic foot ulcers.

Hyperbaric oxygen therapy (HBO) is a short-term, high-dose oxygen inhalation and diffusion therapy, delivered systemically through airways and blood under high pressure using hyperbaric chambers. HBO stimulates angiogenesis, reduces edema, augments granulation tissue formation by enhancing fibroblasts, and improves leukocyte function by elevating the partial pressure of oxygen in tissue. The numbe

Allocation to pollen competitive ability versus seed production in Viola tricolor as an effect of plant size, soil nutrients and presence of a root competitor

In hermaphroditic plants, the effect of a social environment on sex allocation has not been studied to our knowledge, while in hermaphroditic animals such effects are known to be common. In recent years, studies on root competition beyond the effects of nutrients have shown that plants can respond to their conspecific root competitors (social environment), making it interesting to ask if these eff

High temperature simultaneous saccharification and fermentation of starch from inedible wild cassava (Manihot glaziovii) to bioethanol using Caloramator boliviensis.

The thermoanaerobe, Caloramator boliviensis was used to ferment starch hydrolysate from inedible wild cassava to ethanol at 60°C. A raw starch degrading α-amylase was used to hydrolyse the cassava starch. During fermentation, the organism released CO2 and H2 gases, and Gas Endeavour System was successfully used for monitoring and recording formation of these gaseous products. The bioethanol produc

Visual outcome of cataract surgery; Study from the European Registry of Quality Outcomes for Cataract and Refractive Surgery.

PURPOSE: To analyze the visual outcome after cataract surgery. SETTING: Cataract surgery clinics in 15 European countries. DESIGN: Database study. METHODS: Data were drawn from case series of cataract extractions reported to the European Registry of Quality Outcomes for Cataract and Refractive Surgery database. These data were entered into the database via the Web by surgeons or by transfer from e

Key issues in European food science research: a review of the European Food Science Day 2009

This paper is a report on the European Food Science Day (Brussels, 18 November 2009, organized by the CommNet network of food science communicators) and its outcomes. The article presents FP 7 as a key funding mechanism in European food and nutrition research and it puts research in this sector in a socio-economic context. The article then reviews the specific activities of several EU-funded proje

hENT1 expression is predictive of gemcitabine outcome in pancreatic cancer: A systematic review.

High human equilibrative nucleoside transporter 1 (hENT1)-expression has shown a survival benefit in pancreatic cancer patients treated with gemcitabine in several studies. The aim of this systematic review was to summarize the results and try to assess the predictive value of hENT1 for determining gemcitabine outcome in pancreatic cancer. Relevant articles were obtained from PubMed, Embase and Co

Search for contact interactions in dimuon events from pp collisions at root s=7 TeV with the ATLAS detector

A search for contact interactions has been performed using dimuon events recorded with the ATLAS detector in proton-proton collisions at root s = 7 TeV. The data sample corresponds to an integrated luminosity of 42 pb(-1). No significant deviation from the standard model is observed in the dimuon mass spectrum, allowing the following 95% C. L. limits to be set on the energy scale of contact intera

Automatic individualized contrast medium dosage during hepatic computed tomography by using computed tomography dose index volume (CTDIvol)

To compare hepatic parenchymal contrast media (CM) enhancement during multi-detector row computed tomography (MDCT) and its correlation with volume pitch-corrected computed tomography dose index CTDIvol) and body weight (BW). One hundred patients referred for standard three-phase thoraco-abdominal MDCT examination were enrolled. BW was measured in the CT suite. Forty grams of iodine was administer

Some comments and corrections regarding the calculation of electrostatic potential derivatives using the Ewald summation technique

A review of the literature on the calculation of electrostatic potentials, fields, and field gradients in systems consisting of charges and dipoles using the Ewald summation technique is presented. Discrepancies between the previous formulas are highlighted, and an error in the derivation of the reciprocal contributions to the electrostatic field and field gradient is corrected. The new formulas f
