On optimisation of Paganin's method for propagation‐based X‐ray phase‐contrast imaging and tomography

Journal of Microscopy, EarlyView.
Abstract Paganin's method for image reconstruction in propagation‐based phase‐contrast X‐ray imaging and tomography has enjoyed broad acceptance in recent years, with over one thousand publications citing its use. The present paper discusses approaches to optimisation of the method with respect to simple image quality metrics, such as signal‐to‐noise ...

On the treatment of the $\Delta$-contribution in electromagnetic $pp$-knockout reactions [PDF]

, 2005
The treatment of the $\Delta$-current and its contribution in the exclusive $^{16}$O$(e,e'pp)^{14}$C and $^{16}$O$(\gamma,pp)^{14}$C knockout reactions are investigated in combination with the effects of correlations.

Vernalization regulatory network identifies potential novel functions for genes in the HvVRN2 locus

New Phytologist, EarlyView.
Summary Flowering is controlled by environmental and genetic factors. Vernalization requirement in barley (Hordeum vulgare L.) is determined by the allele in HvVRN1 and the presence of locus HvVRN2, which consists of two zinc‐finger and CONSTANS‐like domains (ZCCT) genes: HvVRN2a and HvVRN2b.

Does Soaking Fresh Frozen Costal Cartilage in an Antibiotic Solution Reduce Postoperative Infection in Rhinoplasty?

Plastic and Reconstructive Surgery, Global Open
Background:. Fresh frozen costal cartilage (FFCC), from the Musculoskeletal Transplant Foundation (MTF), has recently gained popularity for use in revision rhinoplasty or primary rhinoplasty when there is a paucity of autologous cartilage. However, there

Prediction of destructive properties using descriptive analysis of nd measurements [PDF]

, 2010
Three groups of measurements related to peach maturity were acquired through destructive (D) mechanical tests (Magness Taylor Firmness, MTF), mechanical non destructive (ND) tests, and ND optical spectroscopy (Optical indexes).

Properties of cosmologies with dynamical pseudo Nambu-Goldstone bosons [PDF]

, 2000
We study observational constraints on cosmological models with a quintessence field in the form of a dynamical pseudo Nambu-Goldstone boson. After reviewing the properties of the solutions, from a dynamical systems phase space analysis, we consider the ...

Original MRE-binding Transcriptional Factor Gene in Normal Humans is ZRF, not MTF-1.

Journal of Health Science, 2001
Metallothionein gene is transcriptionally regulated by heavy metals through cis-acting metal responsive elements (MREs). Two proteins, metal-regulatory transcription factor-1 (MTF-1) and zinc regulatory factor (ZRF), have been isolated and cloned from human cells as MRE-binding transcriptional factor (MREBT). These proteins are almost identical to each

Unfolding Plant Defence: Endoplasmic Reticulum Stress Signalling at the Plant‐Pathogen Interface

Plant Biotechnology Journal, EarlyView.
ABSTRACT The endoplasmic reticulum (ER) stress response, a conserved proteostasis network, has emerged as a central hub that reprograms plant immunity during pathogen attack. This review synthesises how plants harness ER‐stress signalling to mount multilayered defences and how pathogens have evolved counterstrategies to subvert these pathways.
