A prototype of a RBES for personalized menus generation

Applied Mathematics and Computation, 2017
People have many constraints concerning the food they eat. These constraints can be based on religious believes, be due to food allergies or illnesses, or be derived from personal preferences or dislikes. For instance, preparing the menus at a hospital can be really complex.

Dependence on neutron energy of the OER and RBE [PDF]

International Journal of Radiation Oncology*Biology*Physics, 1982
Trials of neutrons as an alternative to x-rays for the radiotherapy of human cancer are underway in Great Britain, the United States, Continental Europe and Japan. The investment of time, effort and resources is considerable and from the outset the need has been recognized for cooperation between centers and across national boundaries. A major obstacle

Influence of Particle Shape and Size in Copper‐Based Low‐Temperature Metallization Paste for Solar Cells

Advanced Engineering Materials, EarlyView.
Particle morphology controls the balance between printability and electrical connectivity in low‐temperature AgCu/Ag metallization pastes. Flake‐shaped AgCu particles form extended low‐resistance contacts, whereas spherical particles favor processability at high metal loading. Fine Ag particles further tune void filling and conductive‐network formation

The Role of Series Cholecystectomy in High Risk Acute Cholecystitis Patients Who Underwent Gallbladder Drainage

Frontiers in Surgery, 2021
Background: Cholecystectomy (CCY) is the only definitive therapy for acute cholecystitis. We conducted this study to evaluate which patients may not benefit from further CCY after percutaneous transhepatic gallbladder drainage (PTGBD) has been performed ...

Single‐Photon Emitters in Thickness‐Controlled hBN Directly Grown on Silicon Platform

Advanced Optical Materials, EarlyView.
Direct, catalyst‐free CVD growth produces thickness‐controlled hBN films on SiO2/Si without transfer. Growth temperature, film thickness, and carbon incorporation tune the density and single‐photon fraction of defect emitters while preserving the hBN lattice structure.

The CXCL5/CXCR2 Axis Attenuates Ferroptosis in Intrahepatic Cholangiocarcinoma Through the Positive Feedback Loop Between PTGS2 Transcriptional Activation and Neutrophil Recruitment

Advanced Science, EarlyView.
The CXCL5/CXCR2 axis directly inhibits ferroptosis in ICC cells by activating the NF‐κB/PTGS2 pathway. Meanwhile, the CXCL5/CXCR2 axis recruits N2 TANs, and the activated PTGS2 promotes the secretion of TNF‐α from the recruited N2 TANs via the CCL2/CCL7/CCR2 pathway, thereby activating the NF‐κB/PTGS2 axis and forming a positive feedback loop, which ...
