Improvements in medical care and technology and reductions in traffic-related fatalities in Great Britain [PDF]

open access: yes
Traffic-related fatalities in the UK have fallen dramatically over the last 30 years by about 50%. This decline has been observed in many other developed countries with similar rates of reduction.

Reducing the complexity of reductions

open access: yes, 2001
We build on the recent progress regarding isomorphisms of complete sets that was reported in Agrawal et al. (1998). In that paper, it was shown that all sets that are complete under (non-uniform) AC0 reductions are isomorphic under isomorphisms ...

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 ...

Resting blood pressure reductions following isometric leg exercise training are associated with improved flow-mediated vasodilatation

open access: yes, 2014
Brachial artery flow-mediated dilatation (BAFMD) is an endothelium-dependant and nitric oxide specific index of endothelial function. The chronic effect of isometric exercise on endothelial function remains equivocal.

Microbiome−host proteostasis crosstalk—An emerging perspective on mechanisms and interventions toward healthy longevity

open access: yesFEBS Letters, EarlyView.
Proteostasis and the gut microbiota play a key role in shaping host physiology. Microbiota‐derived metabolites, vitamins, and RNA modulate host proteostasis. Findings from model systems, including C. elegans, indicate microbes can either stabilize or disrupt host proteostasis.

One-Way Log-Tape Reductions

open access: yes, 1978
One-way log-tape (1-L) reductions are mappings defined by log-tape Turing machines whose read head on the input can only move to the right. The 1-L reductions provide a more refined tool for studying the feasible complexity classes than the P-time [2 ...

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 ...

Query-Monotonic Turing Reductions

open access: yes, 2012
In this paper, we study reductions that make a rapid progression through the set to which they are reducing: Each query is strictly longer (shorter) than the previous one. We call these reductions query-increasing (query-decreasing) Turing reductions. We

Painlevé Analysis and Similarity Reductions for the Magma Equation

open access: yesSymmetry, Integrability and Geometry: Methods and Applications, 2006
In this paper, we examine a generalized magma equation for rational values of two parameters, m and n. Firstly, the similarity reductions are found using the Lie group method of infinitesimal transformations.
