Potato virus Y (PVY) is the most important viral pathogen affecting potato crops worldwide. PVY can be transmitted non-persistently by aphids that do not colonize the host plant, resulting in a rapid acquisition and transmission of the virus between plants. PVY exists as a complex of strains that can be distinguished according to their pathogenicity, serology and genomic analysis. While virus incidence remains low in Scottish seed potato crops, PVY has become the increasingly prevalent virus. The monitoring of PVY(N) and PVY° serotypes has revealed a recent shift towards PVY(N) which now accounts for more than 90% of all PVY cases...

Regular physical activity is an important means of promoting health, both in people and their pets. Walking is the most common method used for dogs, but there is a lack of clarity on how much daily activity different breeds of dog require. Data from an online survey of UK dog owners were collected between June and August in 2014. The University of Liverpool Ethics Committee approved the project, and owners consented to data use. The initial dataset (17 028 dogs) was first cleaned to remove erroneous data, and then edited to remove mixed breed dogs, leaving a total of 12 314 dogs from known pedigree breeds...

Applying shielding coils is a practical way to protect current transformers (CTs) for large-capacity generators from the intensive magnetic interference produced by adjacent bus-bars. The aim of this study is to build a simple analytical model for the shielding coils, from which the optimization of the shielding coils can be calculated effectively. Based on an existing stray flux model, a new analytical model for the leakage flux of partial coils is presented, and finite element method-based simulations are carried out to develop empirical equations for the core-pickup factors of the models...

Ion suppression from the tissue matrix has a severe effect on the mass spectrometry imaging (MSI) of drugs. This problem hinders further applications of MSI in preclinical drug research and development. In this study, an in situ hydrogel conditioning method was developed to enhance the sensitivity of air-flow-assisted desorption electrospray ionization (AFADESI)-MSI. Instead of the traditional washing or digestion treatment in solvent, this method used a solid phase hydrogel to "wash" tissue sections. It was demonstrated that this in situ hydrogel conditioning method improved the drug signal by as much as 2- to 25-fold in MSI, especially for hydrophobic compounds...

We propose the pickup system of integral imaging using the offset lens array (OLA), which is a useful optical component for both the pickup and display processes. The main purpose of our system is resolving the pseudoscopic image problem of integral imaging. Also, the flipped image of integral imaging that has the wrong perspective information can be removed by adding an external barrier in the display process. In this paper, the above properties are explained in detail, and the experimental results to verify the feasibility of the proposed system are presented...

BACKGROUND: Current American Academy of Pediatrics (AAP) recommendations regarding transition from child safety/booster seat to adult safety belt use indicate that children should be at least 4'9", 8 years old, or 80 pounds. Proper fit in the vehicle seat, assessed with a 5 point fit test, should also be met. While most children reach 4'9" around age 8, each child and vehicle presents a unique combination; thus a child may not fit appropriately in all vehicle types using only the 4'9" requirement...

In laboratory testing and in isolation rooms, pickup and transfer of health care-associated pathogens by premoistened rayon swabs correlated well with pickup and transfer by bare hands or moistened gloves. These results suggest that swab cultures provide a useful surrogate indicator of the risk for pathogen pickup and transfer by hands.

We report on the development and deployment of an optical diagnostic for single-shot measurement of the electric-field components of electromagnetic pulses from high-intensity laser-matter interactions in a high-noise environment. The electro-optic Pockels effect in KDP crystals was used to measure transient electric fields using a geometry easily modifiable for magnetic field detection via Faraday rotation. Using dielectric sensors and an optical fibre-based readout ensures minimal field perturbations compared to conductive probes and greatly limits unwanted electrical pickup between probe and recording system...

Influenza C is not included in the annual seasonal influenza vaccine, and has historically been regarded as a minor respiratory pathogen. However, recent work has highlighted its potential role as a cause of pneumonia in infants. We performed nasopharyngeal or nasal swabbing and/or serum sampling (n = 148) in Lancaster, UK, over the winter of 2014-2015. Using enzyme-linked immunosorbent assay (ELISA), we obtain seropositivity of 77%. By contrast, only 2 individuals, both asymptomatic adults, were influenza C-positive by polymerase chain reaction (PCR)...
