In the paper we introduce an optimization framework for traffic restoration in optical wireless networks. As such networks experience multiple partial link failures, we introduce a generic extension of restoration strategies developed for wired networks (that assume total link failures) which enables handling partial link failures as well. The particular traffic restoration strategy studied in the
The kinetics and mechanism for the overall reaction (i) (X = Cl or Br) have been studied at 25.0 °C using stopped-flow spectrophotometry. 3[AuX4]–+ 7SCN–+ 4H2O → 3[Au(SCN)2]–+ HSO4–+ HCN + 12X–+ 6H+ (i), The reaction takes place in two kinetically well separated steps. The initial, rapid process can be identified as stepwise ligand substitutions (ii) (n= 0–3) which take place via direct ligand diThe kinetics and mechanism for the overall reaction (i) (X = Cl or Br) have been studied at 25.0 °C using stopped-flow spectrophotometry. 3[AuX4]–+ 7SCN–+ 4H2O → 3[Au(SCN)2]–+ HSO4–+ HCN + 12X–+ 6H+ (i) The reaction takes place in two kinetically well separated steps.

BACKGROUND: Although smoking and HPV infection are recognized as important risk factors for oropharyngeal cancer, how their joint exposure impacts on oropharyngeal cancer risk is unclear. Specifically, whether smoking confers any additional risk to HPV-positive oropharyngeal cancer is not understood.METHODS: Using HPV serology as a marker of HPV-related cancer, we examined the interaction between
Review of Avner Offer & Gabriel Söderberg, The Nobel Factor
Recently interest has been focused on secretory leucocyte protease inhibitor (SLPI) and its role in immediate hypersensitive reactions, possibly by inhibiting mast cell chymase. The purpose of this investigation was to show whether or not SLPI is produced in mast cells. Double-immunolabelling revealed that SLPI coexists with mast cell tryptase (60%) and chymase (37%). On the other hand, in situ hy
The kinetics for the reactions between the complexes PtCln(H2O)4-n 2−n, n = 0,1,2,3,4, (including cis- and trans-isomers for n=2) and ethene have been studied. In the case of trans-PtCl2(H2O)2, product analysis shows that both the chloride ligand and the aqua ligand are substituted by ethene in two parallel paths, differing in rate by a factor of only 1.5. The experiments show that ethene, and proThe kinetics for the reactions between the complexes PtCln(H2O)4-n 2−n, n = 0,1,2,3,4, (including cis- and trans-isomers for n = 2) and ethene have been studied.

The secretory leukocyte protease inhibitor (SLPI) is a low-molecular- weight inhibitor of proteases, such as elastase and cathepsin G which are released from leukocytes during phagocytosis. The purpose of this study was to determine whether or not SLPI is able to inhibit IgE-mediated histamine release. Nasal mucosa from 11 test subjects without atopic disposition was used for this in vitro study.
Human secretory leucocyte proteinase inhibitor (SLPI) is a low-molecular weight, acid-stable inhibitor of polymorphnuclear granulocyte elastase and cathepsin G. Previous reports have demonstrated the existence of SLPI in the respiratory tract, salivary glands and cervical mucosa. Positive staining for SLPI using immunohistochemical techniques has been reported in serous glands in nasal mucosa. We
The kinetics for the reactions between the six complexes PtCln(H2O)4-n−2n, n = 0,1,2,3,4 (including cis- and trans-isomers for n=2) and the entering ligands Y = Cl−, Br−, I−, SCN−, and DMSO have been studied. The experiments with PtCl42− and trans- PtCl2(H2O)2 give the usual two-term rate constant kexp = k1 + k2[Y], when no extra chloride has been added to the solutions. The parameter k1 can be id
BACKGROUND: Emerging evidence from cohort studies indicates that adiposity is associated with greater incidence of head and neck cancer (HNC). However, most studies have used self-reported anthropometry which is prone to error.METHODS: Among 363 094 participants in the European Prospective Investigation into Cancer and Nutrition study (EPIC) with measured anthropometry, there were 837 incident cas

This paper presents a cylindrical multipole expansion for periodic sources with applications for three-phase power cables. It is the aim of the contribution to provide some analytical solutions and techniques that can be useful in the calculation of cable losses. Explicit analytical results are given for the fields generated by a three-phase helical current distribution and which can be computed e
The development of cationic polymers for anion-exchange membranes (AEMs) with high alkaline stability and conductivity is a considerable challenge in materials chemistry. In response, we here present the synthesis and properties of N-spirocyclic quaternary ammonium ionenes (spiro-ionenes) containing 5- and 6-membered rings fused by central nitrogen cations. High-molecular weight and film-forming s
Hypothesis The adsorbed amount of the polyelectrolyte-like protein histatin 5 on a silica surface depends on the pH and the ionic strength of the solution. Interestingly, an increase in ionic strength affects the adsorbed amount differently depending on the pH of the solution, as shown by ellipsometry measurements (Hyltegren, 2016). We have tested the hypothesis that the same (qualitative) trends
We derive process limit distribution results for the Nelson–Aalen estimator of a hazard function and for the Kaplan–Meier estimator of a distribution function, under different dependence assumptions. The data are assumed to be right censored observations of a stationary time series. We treat weakly dependent as well as long range dependent data, and allow for qualitative differences in the depende
A helicopter flying through an atmosphere containing particulates may accumulate high electrostatic charges which can challenge its operational safety. In this paper we elaborate and validate a triboelectric charging model to predict the electrification experienced by a helicopter while hovering in dusty air. We employed Large Eddy simulations to describe the turbulent structures inherent in the f
