Turbulent Diffusion of Lines and Circulations [PDF]

, 2007
We study material lines and passive vectors in a model of turbulent flow at infinite-Reynolds number, the Kraichnan-Kazantsev ensemble of velocities that are white-noise in time and rough (Hoelder continuous) in space. It is argued that the phenomenon of ``spontaneous stochasticity'' generalizes to material lines and that conservation of circulations ...

Cell Membrane Vesicle Camouflaged Artificial Cells

Advanced Functional Materials, EarlyView.
Artificial cells camouflaged with a cell membrane vesicle coating are able to assemble into synthetic aggregates that exhibit rudimentary communication capabilities. Additionally, when these artificial cells are equipped with antioxidant capabilities, they are able to protect the intracellular homeostasis in HepG2 cells present in semi‐synthetic ...

ExoCubed: A Riemann-solver-based Cubed-sphere Dynamic Core for Planetary Atmospheres

The Astrophysical Journal
The computational fluid dynamics on a sphere is relevant to global simulations of geophysical fluid dynamics. Using the conventional spherical–polar (or lat–lon) grid results in a singularity at the poles, with orders-of-magnitude-smaller cell sizes at ...

Engineering Novel DNA Nanoarchitectures for Targeted Drug Delivery and Aptamer Mediated Apoptosis in Cancer Therapeutics

Advanced Functional Materials, EarlyView.
Designer DNA Architecture‐templated Drug Conjugates (DDA‐DCs) are comprised of a DNA nanomaterial decorated with multiple drug‐loaded DNA aptamers. DDA‐DCs use a combination of multiple aptamer types, each recognizing a different membrane protein to achieve precise targeting of cancer cells.

Higher order dynamic mode decomposition beyond aerospace engineering

Results in Engineering, 2023
It is a well known fact that fluid dynamics play a crucial rule in countless fields in scientific and industrial applications, including nature and medicine (ocean currents, fluid motion around jellyfish, blood circulation...), in energy production (wind

Assessing atmospheric predictability on Mars using numerical weather prediction and data assimilation [PDF]

, 2008
Introduction: Studies of the time series of surface measurements of wind, pressure and temperature at the two Viking landers by Barnes [1], [2] revealed that baroclinic transient travelling waves on Mars occur mostly during northern hemisphere autumn ...

Double Cross‐Linked Hydrogel for Intra‐articular Injection as Modality for Macrophages Metabolic Reprogramming and Therapy of Rheumatoid Arthritis

Advanced Functional Materials, EarlyView.
A hydrogel for intra‐articular injection for the treatment of rheumatoid arthritis (RA) is formulated and comprehensively studied. After administration, the hydrogel induces a metabolic reprogramming of immunometabolism of macrophages to trigger fatty acid oxidation subsequently inducing polarization of anti‐inflammatory M2 macrophages. This results in

Reverse Circulation Drilling Method Based on a Supersonic Nozzle for Dust Control

Applied Sciences, 2016
To reduce dust generated from drilling processes, a reverse circulation drilling method based on a supersonic nozzle is proposed. The suction performance is evaluated by the entrainment ratio.

Dynamical chemical labelling to profile circulating micrornas in body fluids

, 2021
En los últimos años, son numerosos los estudios que se han expandido rápidamente en búsqueda de varios marcadores bioquímicos. Los biomarcadores se definen como moléculas que detectan o confirman la presencia de una condición fisiopatológica, permitiendo así establecer un diagnóstico, un mejor pronóstico, e incluso modificar un tratamiento.

Oxidized Carbon Nanoparticles Enhance Cellular Energetics With Application to Injured Brain

Advanced Healthcare Materials, EarlyView.
Oxidized carbon nanozymes (OCNs) that catalyze the dismutation of superoxide radical and oxidation of reduced nicotinamide adenine dinucleotide (NADH) to NAD+ promote glycolytic and mitochondrial energy metabolism under impaired conditions observed in traumatic brain injury with hemorrhage.
