An Ultra‐Sub‐Wavelength Microwave Polarization Switching Antenna for Covert Communication Implemented With Directed Surface Acoustic Waves in an Artificial Multiferroic Magnonic Crystal

open access: yesAdvanced Materials Technologies, EarlyView.
A surface acoustic wave (SAW) launched in a two‐dimensional periodic array of magnetostrctive nanomagnets on a piezoelectric substrate excites spin waves in the nanomagnets which radiate electromagnetic waves in space. The polarization of the emitted beam in particular directions and at particular frequencies can be switched between horizontal and ...

Na2Fe3(SO4)4: A Zero‐Strain Sustainable Positive Electrode Material for Na‐Ion Batteries

open access: yesAngewandte Chemie, EarlyView.
A new sustainable zero‐strain Na2Fe3(SO4)4 (NFS) positive electrode material is obtained by only ball‐milling from cheap and available Na2SO4 and FeSO4. Iron coordination polyhedra include the Fe2O11 dimer of distorted octahedra (active during cycling) and FeO5 trigonal bipyramid, similar to that in the relative Pbca‐Na2Mn3(SO4)4 (NMS).

Navigating Big Data dilemmas: Feminist holistic reflexivity in social media research

open access: yesBig Data & Society, 2018
Social media offers an attractive site for Big Data research. Access to big social media data, however, is controlled by companies that privilege corporate, governmental, and private research firms.

Numerical Simulation of Nonlinear Lamb Waves Used in a Thin Plate for Detecting Buried Micro-Cracks

open access: yesItalian National Conference on Sensors, 2014
Compared with conventional linear ultrasonic inspection methods, which are sensitive only to severe defects, nonlinear ultrasonic inspection methods are better for revealing micro-cracks in thin plates.

Minimally Invasive Chemical Biopsy Needle with Self‐Wettable Extraction Phase For In Vivo Tissue Sampling During Medical Procedures

open access: yesAdvanced Science, EarlyView.
A new tissue sampling device using an acupuncture needle with bio‐compatible extraction sorbents in the recessed section is developed. The coating material using self‐wettable particles doesn't require solvent activation after sterilization. This device is applied for the anti‐cancer drug concentration monitoring during the in vivo lung perfusion ...

Weak Interaction Contributions in Light Muonic Atoms

open access: yes, 2012
Weak interaction contributions to hyperfine splitting and Lamb shift in light electronic and muonic atoms are calculated. We notice that correction to hyperfine splitting turns into zero for deuterium.

The BSE Crisis and the Price of Red Meat in the UK [PDF]

open access: yes, 2003
This paper presents estimates of price functions for beef, lamb and pork for the UK economy which allow for the effects of the 1996 BSE crisis. Our estimates illustrate the importance of allowing for the joint endogeneity of prices in these markets.

Comprehensive Genetic Map of Muscle Lipidome Reveals Novel Insights Into Flavor Variation in Ruminant Meat

open access: yesAdvanced Science, EarlyView.
Ruminant meat is widely appreciated for its distinctive flavor. Lipids play a central role in influencing meat flavor, yet their genetic and biochemical basis remains largely unexplored. Here, a comprehensive lipid genetic map of sheep muscle is constructed and 20 candidate genes potentially modulating lipid levels are identified to provide a roadmap ...

Modes Control of Lamb Wave in Plates Using Meander-Line Electromagnetic Acoustic Transducers

open access: yesApplied Sciences, 2020
The multimode and dispersion characteristics of Lamb waves make them difficult to apply to nondestructive evaluation. This paper presents a paired configuration of a meander-line coil electromagnetic acoustic transducer (EMAT) to generate a single-mode ...
