(Lipo)polysaccharide interactions of antimicrobial peptides.

Due to rapidly increasing resistance development against conventional antibiotics, as well as problems associated with diseases either triggered or deteriorated by infection, antimicrobial and anti-inflammatory peptides have attracted considerable interest during the last few years. While there is an emerging understanding of the direct antimicrobial function of such peptides through bacterial mem

Testing for panel cointegration with multiple structural breaks

This paper proposes a Lagrange multiplier (LM) test for the null hypothesis of cointegration that allows for the possibility of multiple structural breaks in both the level and trend of a cointegrated panel regression. The test is general enough to allow for endogenous regressors, serial correlation and an unknown number of breaks that may be located at different dates for different individuals. W

Cross-sectional dependency and size distortion in a small-sample homogeneous panel data unit root test

In this paper, we investigate the effects of cross-sectional disturbance correlation in a homogeneous panel data unit root test. As reported by other authors, the unit root test has incorrect size in the presence of cross-sectional correlation. We suggest that a previously known estimator can be used to reduce the size distortions. We supply response surface estimates for critical values and study

From gamma-carboxy-glutamate to protein C.

The story I shall recount started in 1969, when I was given the opportunity to join the Department of Clinical Chemistry at the University Hospital in Malmo. I had just finished medical school at the university in the neighboring town of Lund. Parallel to pursuing my medical studies I had spent some time in the Department of Biochemistry. I did not know much about biochemistry, but it was enough f

Fourier transform infrared spectroscopy of aqueous solutions using optical subtraction

For the analysis of small concentrations of organics in aqueous solutions, a novel add-on accessory for dual-beam / optical subtraction spectroscopy has been built for a commercial Fourier transform infrared spectrometer. A standard FT-IR instrument requires a sample measurement and a separate reference measurement, whereas the optical subtraction instrument directly measures the difference betwee

A simple model for the water o-H-2 complex

The infrared spectrum of the complex between o-H-2 and H2O, D2O, or HDO, isolated in a matrix of solid p-H-2, has been studied between 20 and 4500 cm(-1). In addition the infrared spectrum of the complex between p-D-2 and H2O in solid o-D-2 has been studied. The spectral shifts are interpreted as the result of the quadrupole-dipole interaction between hydrogen and water. (c) 2006 American Institut

Computational Cost of Verifying Enforceable Contracts

This paper explores a new method for evaluating the cost of verifying a contract. We relate these costs to the number of computations an algorithm needs to check that a contract satisfies certain criteria. Two different criteria that facilitate enforcement of the contract are studied. Our findings indicate bounds on the computational costs as the size of the contract grows. If each computation cos
