Termination orderings for rippling [PDF]

open access: yes, 1994
Rippling is a special type of rewriting developed for inductive theorem proving. Bundy et. al. have shown that rippling terminates by providing a well-founded order for the annotated rewrite rules used by rippling. Here, we simplify and generalize this order, thereby enlarging the class of rewrite rules that can be used.

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 ...

Professional identity formation in public health residents: participation in the vast landscape of practice

open access: yesBMC Medical Education
Background With the global shift from curative to preventive care, an increasing number of physicians venture in the field of public health (PH), which could entail changes in their scope of practice and professional identity.

Liver organoids: modelling complexity in homeostasis and disease

open access: yesFEBS Letters, EarlyView.
Studying liver in vitro has been challenging because simple 2D cell cultures fail to capture liver's cellular and architectural complexity. To bridge this gap, scientists increasingly use organoids, 3D liver models which better mimic liver composition and function. This review examines recent advances in liver organoid complexity and realism, discusses

COMPARATIVE STUDY OF EVOLUTIONARY ALGORITHMS TO GENERATE FLAT-TOP BEAM PATTERN FOR SYNTHESIS OF A LINEAR ANTENNA ARRAY

open access: yesICTACT Journal on Communication Technology, 2021
In the present paper three evolutionary algorithms are compared and discussed for synthesizing a linear array of dipole antenna of half-wavelength oriented horizontally. All the dipoles are mutually coupled and designed to radiate the flat-top beam (FTB)

Ligand‐dependent transcriptional heterogeneity in cell cycle gene expression delays G1/S entry

open access: yesFEBS Letters, EarlyView.
EGF and HRG induce distinct G1/S progression programs in ErbB2‐amplified BT474 breast cancer cells. Despite activating the potent ErbB2–ErbB3 heterodimer, HRG does not accelerate cell‐cycle entry. Instead, EGF promotes earlier restriction‐point passage via ERK–FOS signaling, whereas HRG activates the AKT–MYC axis, driving transcriptional heterogeneity ...

Complex spectral interactions encoded by auditory cortical neurons: Relationship between bandwidth and pattern

open access: yesFrontiers in Systems Neuroscience, 2010
The focus of most research on auditory cortical neurons has concerned the effects of rather simple stimuli, such as pure tones or broadband noise, or the modulation of a single acoustic parameter.

Structural and biochemical analysis of a B12 superbinder

open access: yesFEBS Letters, EarlyView.
BtuG proteins are vitamin B12 scavengers in Bacteroides thetaiotaomicron, a dominant human gut bacterium. We present crystal structures of three BtuG homologs bound to cobalamin and its precursor cobinamide, revealing picomolar binding affinities, among the highest known for any natural protein.

Impact of High-Voltage Generator Inverter Frequency on Imaging Performance of Digital Radiography System

open access: yesZhongguo yiliao qixie zazhi
This paper introduces and analyzes the principles and structure inside the high-voltage generator, and for the first time proposes the viewpoint that using an inverter to increase the inverter frequency can enhance the imaging performance of the digital ...
