Unravelling the nonlinear generation of designer vortices with dielectric metasurfaces.
Light Sci Appl

Laboratoire Matériaux et Phénomènes Quantiques, Université Paris Cité and CNRS, Paris, 75013, France.
Vortex beams are currently drawing a great deal of interest, from fundamental research to several promising applications. While their generation in bulky optical devices limits their use in integrated complex systems, metasurfaces have recently proven successful in creating optical vortices, especially in the linear regime. In the nonlinear domain, of strategic importance for the future of classical and quantum information, to date orbital angular momentum has only been created in qualitative ways, without discussing discrepancies between design and experimental results.

We investigate the orientational properties of a homogeneous and inhomogeneous tetrahedral four-patch fluid (Bol-Kern-Frenkel model). Using integral equations, either (i) HNC or (ii) a modified HNC scheme with a simulation input, the full orientational dependence of pair and direct correlation functions is determined. Density functionals for the inhomogeneous problem are constructed via two different methods.

Background: Currently, traditional blood biomarkers such as neuron-specific enolase (NSE), carcinoembryonic antigen (CEA), squamous cell carcinoma antigen (SCCA) etc. are mostly elevated in the late stage of tumour, and patients have already lost the chance of tumour eradication when the relevant indexes are found to be elevated. Therefore, there is a need for blood biomarkers with higher sensitivity, better specificity, and better accessibility.

Department of Medical Imaging, Tongji Hospital, Tongji University, No. 389, Xincun Road, Putuo District, Shanghai, 200065, China.
Objectives: This study aimed to compare apparent diffusion coefficient (ADC) values derived from diffusion-weighted imaging (DWI) of different Borrmann types of advanced gastric cancer (AGC) and correlate these ADC values with Ki-67 expression and serum CEA levels in AGC.
Methods: A total of 84 patients with AGC who underwent DWI of the upper abdomen before tumor resection in our hospital between June 2014 and July 2018 were included in the present study. DWI was obtained with a single-shot echo planar imaging sequence in the axial plane (b values: 0, 100, 700 and 1000 s/mm).
The value-for-money assessment and funding arrangements for high-priced drugs in an era of uncertainty: a comparative analysis of national health technology assessment agencies in South Korea, England, Australia, and Canada.

College of Pharmacy, Gyeongsang National University, 501 Jinju-Daero, Jinju, 52828, Republic of Korea.
Background: Innovative health technologies have increasingly emerged as a promising solution for patients with untreatable or challenging conditions. However, these technologies often come with expensive costs and limited evidence at the time of launch. This study assessed how these high-priced drugs with limited evidence were appraised and introduced in South Korea, England, Australia, and Canada, where cost-effectiveness analysis (CEA) generally plays a central role in pricing and reimbursement decisions.
