Ensembles of binary random LDPC block codes constructed using Hamming codes as constituent codes are studied for communicating over the binary symmetric channel. These ensembles are known to contain codes that asymptotically almost meet the Gilbert-Varshamov bound. It is shown that in these ensembles there exist codes which can correct a number of errors that grows linearly with the code length, w

To evaluate the effect of alcohol cessation on the risk of developing laryngeal and pharyngeal cancers, combining available evidence in the scientific literature in a meta-analysis.

This thesis assesses aspects of the wetland development, permafrost dynamics and associated changes in carbon and nutrient cycling of the Stordalen Mire in northern Sweden. Various ecological and biogeochemical analyses of one peat and two lake sediment sequences were conducted, including analyses of organic matter and carbonate content, mosses, diatoms, testate amoebae, pigments, carbon and nitro

Bell’s palsy is an acute onset of peripheral facial nerve dysfunction. Despite extensive research the aetiology is unclear. The most prevailing theory is that reactivation of viruses such as Herpes simplex type-1 or Varicella zoster may cause Bell’s palsy. The natural course is favourable but at least 30% of patients will suffer sequelae such as residual paresis, synkinesis and/or contracture. The

Investigating the meaning of conceptual terms is an important task for international legal scholars. In the analysis of the usage of conceptual terms in international legal discourse, traditionally, most international lawyers have confined studies to the descriptive meaning of those terms. They have assumed that conceptual terms describe a relationship between, on the one hand, the particular prop

Autochthonous blockfield mantles may indicate alpine surfaces that have not been glacially eroded. These surfaces may therefore serve as markers against which to determine Quaternary erosion volumes in adjacent glacially eroded sectors. To explore these potential utilities, chemical weathering features, erosion rates, and regolith residence durations of mountain blockfields are investigated in the

Profitkvotens tendentiella fall, underkonsumtion eller överproduktion? Få ämnen i den marxistiska tradionen är snårigare än teoribildningen runt det kapitalistiska systemets kriser. Ståle Holgersen tecknar grunddragen i 100 års polemik om ”den rätta teorin”.

To examine whether lower insulin sensitivity as determined by homeostatic model assessment (HOMA-%S) was associated with increased left ventricular mass (LVM) and presence of LV diastolic dysfunction at long-term follow-up, independently of body mass index (BMI), in middle-aged, otherwise healthy males.

A series of bistridentate ruthenium(II) polypyridyl-type complexes based on the novel 2,6-di(quinolin-8-yl)pyridine (dqp) ligand have been synthesized and their photophysical properties have been studied. The complexes are amenable to substitution in the 4-position of the central pyridine with conserved quasi-C-2v symmetry, which allows for extension to isomer-free, rod-like molecular arrays for v

This SpringerBrief focuses on the use of egress models to assess the optimal strategy for total evacuation in high-rise buildings. It investigates occupant relocation and evacuation strategies involving the exit stairs, elevators, sky bridges and combinations thereof. Chapters review existing information on this topic and describe case study simulations of a multi-component exit strategy. This rev

Background: Spot pricing is considered as a significant supplement for building a full-fledged market economy for the Cloud ecosystem. However, it seems that both providers and consumers are still hesitating to enter the Cloud spot market. The relevant academic community also has conflicting opinions about Cloud spot pricing in terms of revenue generation. Aim: This work aims to systematically ide

In this paper we derive a very useful formula for the stochastic representation of the product of a singular Wishart matrix with a normal vector. Using this result, the expressions of the density function as well as of the characteristic function are established. Moreover, the derived stochastic representation is used to generate random samples from product which leads to a considerable improvemen

Background Detecting cognitive impairment in medical inpatients is important due to its association with adverse outcomes. Our aim was to study recognition of cognitive impairment and its association with mortality. Methods 200 inpatients aged over 60 years were recruited at the Department of General Internal Medicine at University Hospital MAS in Malmö, Sweden. The MMSE (Mini-Mental State Exami

Den här artikeln fokuserar arbetsmiljöfrågor relaterade till migrantarbete inom den gröna näringen (jordbruket), och då särskilt säsongsarbete. I synnerhet lyfter artikeln fram den diskriminering och psykosociala ohälsa som i hög utsträckning drabbar migranterna. Eftersom det i dagsläget inte finns någon publicerad forskning avseende nutida förhållanden i Sverige så bygger slutsatserna till stor d

Embryonic stem cells (ESCs) are derived from the inner cell mass (ICM) of blastocyst stage embryos, and upon differentiation into embryoid bodies (EBs) they recapitulate the genetic, cellular and morphological events occurring in early embryogenesis. Among several signalling pathways and inductive factors, the fibroblast growth factors (FGFs) and their receptors (FGFRs) have been shown to be impor

A major concern for contemporary organizations is how to gain support of business processes from standardized software package such as enterprise resource planning (ERP) systems. To gain support adoption of such standardized information and communication technologies (ICTs) demands that either the system is adjusted to existing business processes or that business processes are adjusted to the syst

Background: Studies from Sweden have reported association between immigrant status and incidence of cardiovascular diseases. The nature of this relationship is unclear. We investigated the relationship between immigrant status and risk of heart failure (HF) hospitalization in a population-based cohort, and to what extent this is mediated by hypertension and life-style risk factors. We also explore
