Biomimetic Glycosaminoglycan‐Analog Hydrogel for Improved Embolization of Aneurysms: Environment‐Selective Swelling

open access: yesAdvanced Healthcare Materials, EarlyView.
Biomimetic glycosaminoglycan analog hydrogels exhibit suitable and robust mechanical properties, as well as hemocompatibility and biocompatibility, making them ideal for the embolization of intracranial aneurysms. Notably, the hydrogel's environment‐selective swelling properties enable complete blockage of the aneurysm cavity while preventing ...

Breakthrough Solution for Antimicrobial Resistance Detection: Surface‐Enhanced Raman Spectroscopy‐based on Artificial Intelligence

open access: yesAdvanced Materials Interfaces, EarlyView., 2023
This review discusses the use of Surface‐Enhanced Raman Spectroscopy (SERS) combined with Artificial Intelligence (AI) for detecting antimicrobial resistance (AMR). Various SERS studies used with AI techniques, including machine learning and deep learning, are analyzed for their advantages and limitations.

Invariant solutions and Noether symmetries in Hybrid Gravity

open access: yes, 2014
Symmetries play a crucial role in physics and, in particular, the Noether symmetries are a useful tool both to select models motivated at a fundamental level, and to find exact solutions for specific Lagrangians. In this work, we consider the application

Semiconducting Polymer Nanoparticles as Multimodal Agents for Optical and Magnetic Resonance Imaging

open access: yesAdvanced Healthcare Materials, EarlyView.
Semiconducting polymer nanoparticles (SPNs) exhibit many advantageous optical and biological properties. Multimodal SPN‐based contrast agents that integrate several imaging modalities yield a wealth of information through the use of different imaging mechanisms.

Soft-Pion Theorems for Large Scale Structure

open access: yes, 2014
Consistency relations -- which relate an N-point function to a squeezed (N+1)-point function -- are useful in large scale structure (LSS) because of their non-perturbative nature: they hold even if the N-point function is deep in the nonlinear regime ...

Impact of Fiber Orientation in Electrospun PLA Scaffolds on Fluid Dynamics in a Custom Microfluidic Device

open access: yesAdvanced Healthcare Materials, EarlyView.
Fiber orientation in electrospun scaffolds affects permeability and fluid dynamics in microfluidic devices. Combining experimental data with computational fluid dynamic simulations, we show that aligned fibers enhance flow uniformity, reduce pressure and shear stress variability.

Constraints on Interacting Scalars in 2T Field Theory and No Scale Models in 1T Field Theory

open access: yes, 2010
In this paper I determine the general form of the physical and mathematical restrictions that arise on the interactions of gravity and scalar fields in the 2T field theory setting, in d+2 dimensions, as well as in the emerging shadows in d dimensions ...

Biofabrication of a Filtration Barrier by Integrating Electrospun Membranes and Flow in a Glomerular Co‐Culture

open access: yesAdvanced Healthcare Materials, EarlyView.
An ex vivo glomerular filtration barrier is engineered using electrospun, biomimetic membranes seeded with human glomerular cells. The model supports fenestrated endothelium and podocyte foot processes under flow, mimics size‐selective filtration, and enables disease modeling with hiPSC‐derived podocytes, offering a powerful platform for studying ...

Entanglement, soft modes, and celestial CFT

open access: yesJournal of High Energy Physics
We revisit the calculation of vacuum entanglement entropy in free Maxwell theory in four-dimensional Minkowski spacetime. Weyl invariance allows for this theory to be embedded as a patch inside the Einstein static universe. We use conformal inversions to

Structural Control of Photoconductivity in a Flexible Titanium‐Organic Framework

open access: yesAdvanced Materials, EarlyView.
The concept of flexibility is extended to titanium frameworks and use it to gain control over charge transport. MUV‐35 is a flexible doubly interpenetrated framework that can shrink spontaneously its volume by ≈40% to afford a photoconductive, porous state that is thermodynamically favored by non‐covalent interactions. Abstract The soft nature of Metal‐
