Salmonella lipopolysaccharide‐containing supported lipid bilayers as platforms to study bacteriophage interactions

open access: yesFEBS Letters, EarlyView.
We present robust protocols for the preparation of supported lipid bilayers (SLBs) incorporating either Salmonella smooth LPS or outer membrane vesicles (OMVs). We use a combination of quartz crystal microbalance with dissipation (QCM‐D) and fluorescence microscopy to both characterize the SLBs of various compositions and to probe their interactions ...

Dispersion-managed soliton fiber laser with random dispersion, multiphoton absorption and gain dispersion

open access: yes, 2018
We address the generation and interaction of dispersion-managed dissipative solitons (DMDS) in a model of fiber lasers with the cubic-quintic nonlinearity, multiphoton absorption and gain dispersion.

Wavelength tunable 10-GHz 3-ps pulse source using a dispersion decreasing fiber-based nonlinear optical loop mirror [PDF]

open access: yes, 2004
We experimentally demonstrate the use of a dispersion decreasing fiber (DDF)-based nonlinear optical loop mirror (NOLM) for the generation of wavelength tunable soliton-like pulses at a repetition rate of 10 GHz.

Theoretical Re-evaluations of Scaling Relations between SMBHs and Their Host Galaxies–2. Importance of AGN Feedback Suggested by Stellar Age–Velocity Dispersion Relation

open access: yesFrontiers in Astronomy and Space Sciences, 2017
We present the galactic stellar age—velocity dispersion relation obtained from a semi-analytic model of galaxy formation. We divide galaxies into two populations: galaxies which have over-massive/under-massive black holes (BHs) against the best-fitting ...

From mice to humans—divergent strategies for intestinal homeostasis and regeneration

open access: yesFEBS Letters, EarlyView.
Recent advances such as organoid genome editing, xenotransplantation, imaging, and whole‐genome sequencing have enabled direct studies of human intestinal stem cells (ISCs). These studies reveal species‐specific features, including slower ISC proliferation, distinct injury responses, slower somatic mutation accumulation in humans, and an inverse ...

An examination of the end-over-end shaking technique for measuring soil dispersion

open access: yes, 1997
The end-over-end shaking technique has been widely used to provide a measure of soil dispersibility. However, results are dependent on the specific methodology employed.

Compact orthogonal-dispersion device using a prism and a transmission grating

open access: yesJournal of the European Optical Society-Rapid Publications, 2018
Background Spectroscopy was one of the main applications of gratings. Most spectrometers today are based on reflection grating designs, since high quality transmission grating technologies have only matured over the last several years. Conventional cross-

Dispersion over the Business Cycle: Passthrough, Productivity, and Demand

open access: yesThe Economic Journal
Abstract We characterise the cyclical dispersion of firm-level (physical) productivity and demand shocks using Swedish microdata. Demand shock dispersion increases by more than productivity shock dispersion in recessions and explains most of the variation in sales growth dispersion.

Design and analysis strategies for robust microbiome ageing research

open access: yesFEBS Letters, EarlyView.
The gut microbiome changes with age and associates with age‐related morbidity and mortality, establishing it as a potential biomarker and intervention target for ageing. Realising this potential requires methodological rigour, yet distinguishing biological signals from methodological artefacts remains challenging across cohorts. This review provides an
