Microwave filtering amplifiers

open access: yes, 2021
Els amplificadors filtrants de microones s'han convertit en un tema d'interès a causa de la necessitat de components capaços d'aïllar el sistema d'interferències d'altres circuits. Un exemple de subsistemes destacables en transmissors i receptors de comunicacions són els amplificadors de microones, tant de baix soroll (LNA) com de potència (PA). Durant

Dual pKa Lipid Nanoparticles for Lung‐tropic mRNA Delivery and pH‐Programmed Endosomal Escape

open access: yesAdvanced Science, EarlyView.
Lipid nanoparticles’ bottleneck lies in low endosomal escape efficiency and liver‐dominant delivery after intravenous administration. To overcome these limitations, we present a stepwise pH‐programmed lipid nanoparticle system enabled by our newly synthesized ionizable lipid.

An Optimized Freeze‐Dry Multimodal Workflow for Sequential Micro‐CT Imaging, Histology, and Molecular Profiling: A Use Case in Human Liver Fibrosis

open access: yesAdvanced Science, EarlyView.
Optimized freeze‐drying and eosin staining deliver artifact‐free micro‐CT images of liver tissue at near‐histological detail, then hand the same specimen back for sectioning, staining, and sequencing. Fibrotic volume distinguishes normal liver from cirrhosis, while preserved RNA reveals inflammatory gene upregulation—one biopsy, three dimensions, and a

Diffusion Model Inverse Modeling and Applications to Microwave Filters

open access: yes
This paper presents a framework for inverse modeling of microwave filters based on a conditional diffusion model developed to address the intrinsic non-uniqueness of reconstructing coupling matrices from specified S-parameter responses.

Hyper‐Intense Tumor Peripheral Accumulation of Antibody‐Conjugated Iron Oxide Nanoparticles can Enable Breast Cancer Detection by Magnetic Particle Imaging

open access: yesAdvanced Science, EarlyView.
Tumor‐associated inflammation retains antibody‐targeted or non‐specific antibody conjugated nanoparticles within the tumor microenvironment. Magnetic Particle Imaging (MPI) enables non‐invasive detection and differentiation of tumors from other organs, owing to higher nanoparticle retention by inflammatory cells in the tumor periphery.

Chemotherapy‐Activated GSK3β‐DNMT1 Signaling Upregulates CD47 to Evade Macrophage Phagocytosis and Drive Temozolomide Resistance in Glioblastoma

open access: yesAdvanced Science, EarlyView.
Temozolomide treatment activates GSK3β, driving DNMT1 phosphorylation, destabilization, and CD47 promoter hypomethylation in glioblastoma. This epigenetic shift upregulates CD47, enabling TMZ‐treated GBM cells to evade macrophage phagocytosis, survive chemotherapy, and acquire resistance.

Multiband waveguide filters with advanced filtering characteristics based on an in‐band transmission zeros method and stacked cylindrical resonators

open access: yesIET Microwaves, Antennas & Propagation
This paper significantly improves the previously proposed novel multiband waveguide filter implementation employing cylindrical resonators. The improved model has the advantages of a further reduced footprint using stacking shunt resonators horizontally ...

AHR‐Responsive Carbon Dots Orchestrate Skin Wound Healing and Colonic Mucosal Repair via Treg‐Mediated Macrophage Efferocytosis

open access: yesAdvanced Science, EarlyView.
Guided by pharmacophore modeling and molecular docking, aryl hydrocarbon receptor (AHR)‐responsive carbon dots were synthesized. They bind directly to AHR and expand gut‐resident regulatory T (Treg) cells. Treg‐derived C‐C motif chemokine ligand 1 (CCL1) enhances macrophage efferocytosis, creating a pro‐regenetative niche that promotes colonic mucosal ...
