Routing and Downlink Resource Allocation for Multicast Traffic in LEO Satellite Constellations

International Journal of Satellite Communications and Networking, EarlyView.
ABSTRACT In this work, we optimize unicast and multicast traffic delivery over non‐terrestrial networks (NTNs) to users on the ground through direct satellite downlink (DL). We consider a gateway‐free mesh architecture with low Earth orbit (LEO) satellites interconnected via inter‐satellite links (ISLs), where unicast and multicast services compete for

Biopolymer‐Based Polyelectrolyte Nanoplatforms for Targeted Photodynamic Therapy of Breast Cancer

VIEW, EarlyView.
Illustration of the synthesis of 5‐aminolevulinic acid loaded chitosan‐sericin polyelectrolyte nanoparticles (CSSN/ALA NPs) using the Flash nanocomplexation (FNC) technique and their potential in photodynamic therapy (PDT) against breast cancer (BC). Abstract Nanomedicine has reshaped healthcare, especially in targeted drug delivery systems (DDSs) and ...

Beyond monofunctionality: structural perspectives on phenol oxidase side activity in a catalase

Acta Crystallographica Section D, EarlyView.
Structural and biochemical characterization of the extracellular fungal catalase ClCPO uncovers an unexpected phenol oxidase promiscuity. Crystal structures, substrate docking and electron‐transfer pathway analysis identify ligand‐binding regions and support a working mechanistic model for catalase‐associated phenol oxidase activity.Catalases are ...

Multiphysics Finite Element Analysis of Diffusive–Bioconvective MHD Hybrid Nanofluid Flow Over an Exponentially Stretching Sheet

Advances in Mathematical Physics
This study examines the diffusive–bioconvective magnetohydrodynamic (MHD) flow of a hybrid nanofluid past an exponentially stretching sheet embedded in a porous medium, incorporating thermal radiation, viscous dissipation, Soret–Dufour effects, and ...

Soret feedback in thermal diffusion of suspensions [PDF]

, 1998
We have theoretically studied the interaction of a light beam with liquids containing absorbing nanoparticles. We have shown that the Soret effect ensures a feedback that essentially limits heat insertion into the system and the change in its temperature:

Training and validation of an automated algorithm to differentiate no and minimal diabetic retinopathy from more severe stages in wide‐field images

Acta Ophthalmologica, EarlyView.
Abstract Purpose Diabetic retinopathy (DR) is a leading cause of blindness in the working‐age population. Screening is essential to identify and treat sight‐threatening stages prior to irreversible visual loss. This study aimed to train and validate an automated algorithm to identify no or minimal DR, potentially saving resources for specialist ...

Familial Co‐Aggregation of Neurodevelopmental Conditions and Childhood‐Onset Type 1 Diabetes

Acta Paediatrica, EarlyView.
ABSTRACT Aim Childhood‐onset Type 1 diabetes (T1D) is associated with neurodevelopmental conditions (NDCs). We examined whether this association extends to relatives and assessed phenotypic, genetic, and environmental correlations between T1D and NDCs.

Soret and Dufour effects on free convective heat and solute transfer in fluid saturated inclined porous cavity

Engineering Science and Technology, an International Journal, 2015
The present problem addresses double diffusive free convection in an inclined square cavity filled with fluid saturated porous medium under the influence of Soret and Dufour effects. The inclined cavity makes an angle with the horizontal plane.

Afamelanotide improves quality of life and light tolerance in Austrian erythropoietic protoporphyria patients

JDDG: Journal der Deutschen Dermatologischen Gesellschaft, EarlyView.
Summary Background Erythropoietic protoporphyria (EPP) is a rare genetic disorder characterized by severe phototoxic reactions that occur within minutes of light exposure. In clinical studies, afamelanotide has been shown to prolong pain‐free sun exposure, improve quality of life, and reduce the frequency and severity of phototoxic reactions ...
