Introduction: The development of high-performance radiofrequency (RF) coil arrays is critical for improving image quality and signal-to-noise ratio (SNR) in preclinical imaging applications. The AirLink Multi-Resonator Array (MRA) has demonstrated promising capabilities in human imaging, and this study aims to evaluate its performance in animal models. The objective is to assess the array’s...
TRansmit Array Spatial Encoding (TRASE) Magnetic Resonance Imaging (MRI) is a method for MRI which uses an array of Radio Frequency (RF) transmission coils that produce RF (B1 ) field phase gradients to spatially encode imaging information. TRASE MRI has allowed progress in the development of low-field, gradient-free MRI designs. These designs are compact MRI designs that could be deployed in...
We carry out molecular dynamics simulations of peptides confined within aqueous nanodroplets and investigate the influence of the temperature-dependent properties of the nanodroplets on peptide folding, localization within the nanodroplet, and secondary structure. Recent computational studies from our group have revealed the emergence of thermodynamic and structural anomalies in liquid water...

1.1 Introduction
Venous pressure measurements hold significant clinical importance in intensive
care units, where hemorrhagic shock is a common concern. Traditionally, as-
sessing venous pressure has required catheterization, a risky invasive procedure.
Photoplethysmography (PPG) offers a non-invasive alternative through optical
sensing, where fluctuations in local blood...

Abstract
Introduction:
Imaging deep tissue structures, such as blood vessels, in scattering media like skin is challenging for optical techniques. This study enhances Spatio-Angular Filtering...
Introduction Positron Emission Tomography (PET) uses radiotracers to visualize the function of the body. The radioactive atom, which is part of the radiotracer, decays through positive beta decay and releases two 511 keV photons in opposite directions. The photons are used to map the location of radiotracers. PET can be used to locate malignant tumours, and for understanding strokes, dementia,...
Nucleation is the process by which liquids crystallize during a first order transition. However, despite being an inherently kinetic process, most theoretical approaches focus on the thermodynamics of cluster formation, often using the bulk properties of the perfect crystal as ingredients. Our recent work explores approaches to nucleation that focus on the influence of the monomer addition and...
The brain is composed of various cells, including neurons which transmit electrical signals via axons. These axons, grouped together in fibre tracts, make up the brain’s white matter. Postmortem studies suggest that changes in axon diameter and density within the fibre tracts are associated with disorders such as Alzheimer's disease, schizophrenia, autism spectrum disorders, and more. In vivo...
