Non-Toxigenic Clostridioides difficile Strain E4 (NTCD-E4) Prevents Establishment of Primary C. difficile Infection by Epidemic PCR Ribotype 027 in an In Vitro Human Gut Model
(2023-02-22)Clostridioides difficile infection (CDI) remains a significant healthcare burden. Non-toxigenic C. difficile (NTCD) strains have shown a benefit in preventing porcine enteritis and in human recurrent CDI. In this study, ... -
A non-transitive trust model for key distribution
(2010)Key distribution mechanisms such as PKI or PGP implicitly assume trust to be transitive. This can be a problematic assumption. The user relies indirectly (often implicitly) on the remote entities to satisfy its trust ... -
Nonclassicality of states and measurements by breaking classical bounds on statistics
(2009)We derive exceedingly simple practical procedures revealing the quantum nature of states and measurements by the violation of classical upper bounds on the statistics of arbitrary measurements. Data analysis is minimum, ... -
Nonconsultant career grade doctors in dermatology : a hidden resource
(2005)Since the publication of the NHS Plan in 2000, there has been much emphasis on the development of general practitioners with a special interest (GPwSI) in dermatology.The NHS Modernisation Agency Action on Dermatology (AoD) ... -
Noncontact measurement of the local mechanical properties of living cells using pressure applied via a pipette
(2008)Mechanosensitivity in living biological tissue is a study area of increasing importance, but investigative tools are often inadequate. We have developed a noncontact nanoscale method to apply quantified positive and negative ... -
Nonlinear effects of unbalance in the rotor-floating ring bearing system of turbochargers
(2013-01-01)Turbocharger (TC) rotor-floating ring bearing (FRB) system is characterised by high speed as well as high non-linearity. Using the run-up and run-down simulation method, this paper systematically investigates the influence ... -
Nonlinear effects on pulsed laser propagation in the atmosphere
(1988-02)Nonlinear effects on the propagation of a high power pulsed laser beam through the earth’s atmosphere are modeled. Stimulated Raman scattering in relatively modest power laser beams is estimated to be very significant when ... -
The nonlocal, local and mixed forms of the SPH method
(2021-12-15)From its early days the SPH method has been criticised for its shortcomings namely tensile instability and consistency. Without thorough understanding of the method attempts were made to make the classical SPH method ... -
Nonspecific synaptic plasticity improves the recognition of sparse patterns degraded by local noise
(2017-04-20)Many forms of synaptic plasticity require the local production of volatile or rapidly diffusing substances such as nitric oxide. The nonspecific plasticity these neuromodulators may induce at neighboring non-active synapses ... -
Nonthermal Radio Continuum Emission from Young Nearby Stars
(2022-05-23)Young and magnetically active low-mass stars often exhibit nonthermal coronal radio emission owing to the gyration of electrons in their magnetized chromospheres. This emission is easily detectable at centimeter wavelengths ... -
Nonvolatile CMOS memristor, reconfigurable array and its application in power load forecasting
(2023-12-29)The high cost, low yield, and low stability of nano-materials significantly hinder the application and development of memristors. To promote the application of memristors, researchers proposed a variety of memristor emulators ... -
Noradrenergic mechanisms in the prefrontal cortex.
(1997)There is growing evidence that noradrenergic inputs to the prefrontal cortex (PFC) play an important role in regulating its function. This paper reviews the pharmacological control of noradrenaline (NA) release in this ... -
Normal and language-impaired children's use of reference: syntactic vs pragmatic processing
(2003)The present study investigates children's syntactic and pragmatic processing when specifying referents presented in short video clips. Within Relevance theory, the assumption of 'optimal relevance' implies that utterances ... -
Normal black holes in bulge-less galaxies: the largely quiescent, merger-free growth of black holes over cosmic time
(2018-05-11)Understanding the processes that drive the formation of black holes (BHs) is a key topic in observational cosmology. While the observed M BH-M Bulge correlation in bulge-dominated galaxies is thought to be produced by major ... -
Normal Enough? Tools to Aid Decision Making
(2017-03-04)When undertaking quantitative hypothesis testing, social researchers need to decide whether the data with which they are working is suitable for parametric analyses to be used. When considering the relevant assumptions ... -
'Normal' Fanaroff–Riley type II radio galaxies as a probe of the nature of X-shaped radio sources
(2008)We present amultiwavelength radio study of a sample of nearby Fanaroff-Riley class II (FRII) radio galaxies,matched with the sample of known X-shaped radio sources in size, morphological properties and redshift, using new ... -
‘Normal’ semantic-phonemic fluency discrepancy in Alzheimer's disease? A meta-analytic study
(2010)In a meta-analysis of 135 studies involving 6000 patients with Alzheimer's disease (AD) and 6057 healthy controls, we examined the relative degree of semantic and phonemic fluency impairment in AD patients. The effect size ...
