Arrays of nanoparticle-supported lipid bilayers (nanoSLB) are lipid-coated nanopatterned interfaces that provide a platform to study curved model biological membranes using surface-sensitive techniques. We combined scattering techniques with direct imaging, gain access sub-nanometer scale structural information on stable nanoparticle monolayers assembled silicon crystals in noncovalent manner Langmuir-Schaefer deposition. The structure supported formed the arrays via vesicle fusion was...

Regularized models are often sensitive to the scales of features in data and it has therefore become standard practice normalize (center scale) before fitting model. But there many different ways choice may have dramatic effects on resulting In spite this, so far been no research this topic. paper, we begin bridge knowledge gap by studying normalization context lasso, ridge, elastic net regression. We focus normal binary show that class balances directly influences regression coefficients...

SUMMARY We describe the new microsporidium Hamiltosporidium tvaerminnensis gen. et sp. nov. with an emphasis on its ultrastructural characteristics and phylogenetic position as inferred from sequence data of SSU rDNA, alpha- beta-tubulin. This parasite was previously identified Octosporea bayeri Jírovec, 1936 has become a model system to study ecology, epidemiology, evolution genomics microsporidia - host interactions. Here, we present evidence that shows differences O. bayeri. exclusively...

Abstract Purpose – Recently there has been a strong trend towards automation in the mine industry. This paper seeks to describe and analyse an algorithm that can be used as part of infrastructure‐free reactive navigation system for autonomous vehicles underground mines. Design/methodology/approach The idea presented here enable is combine behaviours tunnel following, with topological localization. To assess reliability precision corridor detection real data recorded both indoor environments...

Objectives: To analyze a cohort of 745 consecutive patients referred to regional specialist clinic for evaluation post-traumatic neck pain during five-year period.Methods: A cross-sectional observational study baseline assessments performed by multi-professional rehabilitation teams according standardized checklist.Results: The contained nearly twice as many females males (64% versus 36%). type injury did not differ between sexes. Of the entire cohort, 38% were diagnosed with widespread...
