Article Abstract

We report a first-principles study of static transport of localized waves in quasi-one-dimensional open media. We find that such transport, dominated by disorder-induced resonant transmissions, displays novel diffusive behavior. Our analytical predictions are entirely confirmed by numerical simulations. We show that the prevailing self-consistent localization theory [B. A. van Tiggelen, Phys. Rev. Lett. 84, 4333 (2000)] is valid only if disorder-induced resonant transmissions are negligible. Our findings open a new direction in the study of Anderson localization in open media.

Clinical Relevance: Dry eye disease (DED) is associated with use of video screen based gadgets and long hours spent looking through microscopes. Use of 3D goggles to view 3D screens leads to eye strain and worsening of dry eye symptoms. It is important to identify and treat the symptoms in professions carrying a high risk of DED.

Background: Over the past decade, remote (non-face-to-face) services are being increasingly used in primary care, including interactions through telephone and online platforms. These services bring potential benefits as well as potential barriers for patients. Older migrants are a population that could face intersectional barriers when accessing healthcare; it is important to understand the impact of remote services on them.

Introduction: Combined vascular endothelial growth factor/programmed death-ligand 1 blockade through atezolizumab/bevacizumab (A/B) is the current standard of care in advanced hepatocellular carcinoma (HCC). A/B substantially improved objective response rates compared with tyrosine kinase inhibitor sorafenib; however, a majority of patients will still not respond to A/B. Strong scientific rationale and emerging clinical data suggest that faecal microbiota transfer (FMT) may improve antitumour immune response on PD-(L)1 blockade.

Background: Nasopharyngeal carcinoma (NPC) presents significant nutritional challenges during concurrent chemoradiotherapy, adversely affecting treatment outcomes and quality of life. Non-pharmacological interventions may help improve nutritional and immune status, reduce complications and enhance overall well-being. However, evidence of their effectiveness is scattered and inconsistent, and no systematic review has yet synthesised the evidence on their effectiveness.

Introduction: Relational continuity of care (RCC) refers to the sustained therapeutic relationship between a patient and a clinician, which fosters trust, enhances communication and facilitates the accumulation of knowledge about the patient. RCC is associated with enhanced patient outcomes, reduced hospital admissions, lower mortality rates, decreased healthcare costs and improved patient experience. Despite these benefits, reorganisations within the NHS and workforce challenges have led to an increased reliance on multidisciplinary and part-time working, resulting in fragmented care and a decline in RCC.
