Hepatocellular Carcinoma Risk Factors and Disease Burden in a European Cohort: A Nested Case-Control Study.

Background: To date, no attempt has been made to systematically determine the apportionment of the hepatocellular carcinoma burden in Europe or North America among established risk factors.MethodsUsing data collected from 1992 to 2006, which included 4 409 809 person-years in the European Prospective Investigation into Cancer and nutrition (EPIC), we identified 125 case patients with hepatocellula

Getting the balance right between functional and non-functional requirements: the case of requirement specification in IT procurement

IT procurement represents a business process of high importance, including the ability to articulate requirements that the procurement deals with. Furthermore, specifying requirements is of importance for both procurer and potential supplier, as it functions as central contractual element between the two. The purpose of this article is two-fold: (i) to show how established terminology for requirem

Urban snowmelt and runoff in northern Sweden

Snowmelt and runoff in urban areas in Lulea, north Sweden, are discussed and compared with rural conditions. The uneven snow distribution in cities is quantified. Energy fluxes at the snow surface in different environments are estimated. It is shown that, mainly because of increased absorbed radiative energy in the snow, the daily melt is about 10 mm higher in the city than in rural environments.

Linearity of bulk-controlled inverter ring VCO in weak and strong inversion

In this paper linearity of frequency modulation in voltage controlled inverter ring oscillators for non feedback sigma delta converter applications is studied. The linearity is studied through theoretical models of the oscillator operating at supply voltages above and below the threshold voltage of a transistor, bringing the transistors in respectively strong and weak inversion. The theoretical re

SIMULATED DOSE REDUCTION BY ADDING ARTIFICIAL NOISE TO MEASURED RAW DATA: A VALIDATION STUDY.

The purpose of this study was to verify and validate a noise simulation tool called Dose Tutor (VAMP GmbH) in terms of level and texture of the simulated noise. By adding artificial noise to measured computed tomography (CT) raw data, a scan acquired with a lower dose (mAs) than the actual one can be simulated. A homogeneous polyethylene phantom and an anthropomorphic chest phantom were scanned fo

Prestudy on diffusion and transient condensation of water vapor in cement mortar

The kinetics of sorption of water vapor in mature cement mortar are examined experimentally by the use of a sorption balance (DVS1000). The relative humidity in the sample chamber is obtained by mixing dry and saturated air using flow regulators with very high accuracy. A predefined change of relative humidity in the sample chamber can be obtained in about 30 s. The time needed for equilibration i

A real-time assimilation algorithm applied to near-surface ocean winds

Marine operations depend on the ability to forecast suddenly appearing storms and failures often cause great damage. As a part of a sea state alarm study, meteorological forecasts overlaid with satellite measurements sent to ships have been found to be a useful tool. In this paper we present a real-time assimilation algorithm that extends this tool using statistical methods. The algorithm is appli

Exercise and asthma: an overview.

The terms 'exercise-induced asthma' (EIA) and 'exercise-induced bronchoconstriction' (EIB) are often used interchangeably to describe symptoms of asthma such as cough, wheeze, or dyspnoea provoked by vigorous physical activity. In this review, we refer to EIB as the bronchoconstrictive response and to EIA when bronchoconstriction is associated with asthma symptoms. EIB is a common occurrence for m

Psychoanalytic conceptions of the mind in relation to personality disorders of drug abusers.

The purpose was to investigate whether signs of DMTm (Defense Mechanism Technique modified) could discriminate between the ten groups of DSM-III-R personality disorders (PDs) and DSM-III-R clusters among drug abusers. DMTm signs are interpreted as different kinds of defense and anxiety. The 65 subjects were recruited from Sabbatsberg Hospital, Sweden. Prominent affect defenses were projected intro

WLC31-4: Optimal Signaling for Single Transmit Antenna Selection with Erroneous Feedback

We consider a MIMO system where error-prone feedback from the receiver is used by the transmitter to select a single optimum antenna to transmit data. Such error-prone feedback is common in the bandwidth-limited real systems, and is in marked contrast with the idealizations assumed in the selection literature. We show how the signaling assignment, which maps the antenna indices to the codewords th

Thrombomodulin gene c.1418C>T polymorphism and risk of recurrent venous thromboembolism.

Thrombomodulin gene (THBD) is a critical cofactor in protein C anticoagulant system. THBD c.1418C>T polymorphism is reported to be associated with higher risk of primary venous thromboembolism (VTE) but its role in VTE recurrence is unknown. The aim of this study was to investigate the role of THBD polymorphism in VTE recurrence. THBD c.1418C>T polymorphism was genotyped by using Taqman polymerase
