On the theory of list decoding of convolutional codes

Lower bounds on the list minimum weight and list weight are obtained for ensembles of systematic and nonsystematic encoders. >From these bounds it follows that the necessary list size grows exponentially with the number of corrected errors. We obtain an expurgated upper bound on the probability of the correct path loss for the ensemble of time-invariant binary convolutional codes. The notion of an

Tomosynthesis in pulmonary cystic fibrosis with comparison to radiography and computed tomography: a pictorial review.

The purpose of this pictorial review is to illustrate chest imaging findings of cystic fibrosis (CF) using tomosynthesis (digital tomography), in comparison to radiography and computed tomography (CT). CF is a chronic systemic disease where imaging has long been used for monitoring chest status. CT exposes the patient to a substantially higher radiation dose than radiography, rendering it unsuitab

Maternal Exposure to Air Pollution and Birth Outcomes.

Background: The knowledge about air pollution effects on birth weight, prematurity and small for gestational age [SGA] in low-exposure areas is insufficient. Objectives: The aim of this birth cohort study was to investigate if low-level exposure to air pollution was associated with prematurity and foetal growth and if there are gender specific effects. Method: We combined high quality registry inf

THE EFFECT OF DIFFERENT ADAPTATION STRENGTHS ON IMAGE QUALITY AND RADIATION DOSE USING SIEMENS CARE DOSE 4D.

The purpose of this study was to evaluate the effect of different choices of adaptation strengths on image quality and radiation exposure to the patient with Siemens automatic exposure control system called CARE Dose 4D. An anthropomorphic chest phantom was used to simulate the patient and computed tomography scans were performed with a Siemens SOMATOM Sensation 16 and 64. Owing to adaptation stre

Som vem som helst : Kön, funktionalitet och idrottande kroppar

Popular Abstract in Swedish Avhandlingens huvudsakliga syfte är att utforska unga kvinnors levda erfarenheter av en kropp som å ena sidan betraktas som avvikande – den fysiskt funktionsnedsatta eller rörelsehindrade kroppen – å andra sidan betraktas som presterande – den idrottande kroppen. De frågor som ställs i avhandlingen är hur de unga kvinnorna förhandlar de båda subjektspositioner som uppstThe main aim of this thesis is to explore young women’s lived experience of the body, which, on one hand, is viewed as deviant – the disabled body – and, on the other hand, is viewed as accomplished – the sporting body. The questions posed in the thesis are the following: how do the young women handle the two subject positions that emerge as a result of the perception of them as respectively devia

Clinicopathologic factors identify sporadic mismatch repair-defective colon cancers.

Identification of sporadic mismatch repair (MMR)-defective colon cancers is increasingly demanded for decisions on adjuvant therapies. We evaluated clinicopathologic factors for the identification of these prognostically favorable tumors. Histopathologic features in 238 consecutive colon cancers were linked to MMR status based on immunostaining and BRAF mutation status.MMR defects were identified

Studies of Porphyrin-containing Specimens Using An Optical Spectrometer Connected To A Confocal Scanning Laser Microscope

A spectrometer has been developed for use with a confocal scanning laser microscope. With this unit, spectral information from a single point or a user-defined region within the microscope specimen can be recorded. A glass prism is used to disperse the spectral components of the recorded light over a linear CCD photodiode array with 256 elements. A regulated cooling unit keeps the detector at 277

Cross-cultural validity of the Individualised Care Scale - a Rasch model analysis.

Aims and objectives: The aim of this study was to investigate, using Rasch model analysis, the measurement invariance of the item ratings of the Individualised Care Scale. Background. Evidence of reliability is needed in cross-cultural comparative studies. To be used in different cultures and languages, the items must function the same way. Design: A methodological and comparative design. Meth

Ability of physical activity measurements to assess health-related risks.

The aim of this study is to evaluate if two different physical activity (PA) questionnaires have similar ability to rank individuals, and to examine associations with cardiovascular-metabolic risk factors, compared to an objective measure. In a random sample (n=369, age: 65+/-6 years) from the population-based 'Malmö Diet and Cancer' (MDC) cohort, PA was measured by a leisure-time comprehensive qu
