Failure disjoint paths
Given a weighted directed graph where some arcs can fail while others are reliable, we aim to compute a shortest pair of failure-disjoint paths. If a reliable arc is used by both paths, its cost is counted only once. We present a polynomial time algorithm to solve the problem.

Hom-Lie Admissible Hom-coalgebras and Hom-Hopf Algebras
The aim of this paper is to generalize the concept of Lie-admissible coalgebra introduced by Goze and Remm to Hom-coalgebras and to introduce Hom-Hopf algebras with some properties. These structures are based on the Hom-algebra structures introduced by the authors.
Coffee Consumption and CYP1A2*1F Genotype Modify Age at Breast Cancer Diagnosis and Estrogen Receptor Status.
CYP1A2 plays a key role in the metabolism of both estrogen and coffee. Women with higher coffee intake and the CYP1A2*1F A/A genotype have a ratio of high 2-hydroxyestrone (2-OHE1) to 16alpha-OHE1. 2-OHE1 is a weak estrogen and may even block the estrogen receptor (ER), whereas 16alpha-OHE1 is procarcinogenic. We hypothesized that moderate to high coffee consumption (>/=2 cups per day) combined wi

Liberty, Law and Leviathan. Of Being Free from Impediments by Artifice
The argument in this paper is that Hobbes’ theory of freedom in Leviathan allows for four ways of being free to act – corporal freedom by nature, freedom from obligation by nature, the freedom to disobey, and the freedom of no-rule – each corresponding to a particular absence, some of which make sense only in the civil state. Contrary to what some have claimed, this complexity does not commit Hobb

Plasticity in hydraulic architecture of Scots pine across Eurasia
Widespread tree species must show physiological and structural plasticity to deal with contrasting water balance conditions. To investigate these plasticity mechanisms, a meta-analysis of Pinus sylvestris L. sap flow and its response to environmental variables was conducted using datasets from across its whole geographical range. For each site, a Jarvis-type, multiplicative model was used to fit t
Survival in cancer patients with previous hospitalization for sarcoidosis: a Swedish population-based cohort study during 1964-2006.
BACKGROUND: Sarcoidosis has been reported to be associated with an increased risk of cancer; however, little information is available about the prognosis for sarcoidosis patients diagnosed with cancer. PATIENTS AND METHODS: A population-based cohort of sarcoidosis patients was identified from Swedish registers. Cause-specific and overall hazard ratios (HRs) were estimated by using Cox regression m
Protein E of Haemophilus influenzae Is a Ubiquitous Highly Conserved Adhesin.
Protein E (PE) of nontypeable Haemophilus influenzae (NTHi) is involved in adhesion and activation of epithelial cells. A total of 186 clinical NTHi isolates, encapsulated H. influenzae, and culture collection strains were analyzed. PE was highly conserved in both NTHi and encapsulated H. influenzae (96.9%-100% identity without the signal peptide). PE also existed in other members of the genus Pas

Forskningskvantitet viktigare än kvalitetet?
Artificiella neurala nätverk underlättar svåra medicinska beslut. Exempel från pankreatologin.
Artificial neural networks (ANNs) is a nonlinear pattern recognition technique inspired by the function of the human brain. ANNs have been used successfully in analysis of complex medical relationships, for example prognostic predictions of various forms of cancer. Acute pancreatitis and pancreatic cancer are commonly recognized to be extremely difficult conditions in making diagnostic and prognos
Effects of irrigation and water content of packings on alpha-pinene vapours biofiltration performance
The main objective of this investigation is to determine the effect of different physical parameters on the performance of biofilters, treating hydrophobic compounds. In this respect, the effects of irrigation and water content of packings on the removal efficiency of bed in different pollutant loading rates, and gas phase flow rates, is studied. Alpha-pinene, which is produced from variety of ind
