Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system

FEBS Letters, EarlyView.
Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.

A Projection Method for Locally Refined Grids

Journal of Computational Physics, 1996
A numerical method for the solution of the two-dimensional Euler equations for incompressible flow on locally refined grids is presented. The method is a modified second-order Godunov-projection method. Second-order accuracy of the numerical method in time and space is established through numerical experiments.

Organizing the interface—Plasma membrane architecture and receptor dynamics in virus‐cell interactions

FEBS Letters, EarlyView.
Plasma membranes contain dynamic nanoscale domains that organize lipids and receptors. Because viruses operate at similar scales, this architecture shapes early infection steps, including attachment, receptor engagement, and entry. Using influenza A virus and HIV‐1 as examples, we highlight how receptor nanoclusters, multivalent glycan interactions ...

Multi-View Feature Fusion and Rich Information Refinement Network for Semantic Segmentation of Remote Sensing Images

Remote Sensing
Semantic segmentation is currently a hot topic in remote sensing image processing. There are extensive applications in land planning and surveying. Many current studies combine Convolutional Neural Networks (CNNs), which extract local information, with ...

2D Large Eddy Simulation of Turbulent Boundary Flow around a Controlled-Diffusion Wing Section Using a Locally Refined Unstructured Grid

NUST Journal of Engineering Sciences, 2008
In this study, a 2D large eddy simulation of the flow around a thin, cambered, controlled-diffusion airfoil was carried out. An embedded local mesh refinement technique was used to achieve very fine near-wall resolution while maintaining a coarse mesh ...

Instance Mask Embedding and Attribute-Adaptive Generative Adversarial Network for Text-to-Image Synthesis

IEEE Access, 2020
Existing image generation models have achieved the synthesis of reasonable individuals and complex but low-resolution images. Directly from complicated text to high-resolution image generation still remains a challenge.

Corrective gradient refinement for mobile robot localization

2011 IEEE/RSJ International Conference on Intelligent Robots and Systems, 2011
Particle filters for mobile robot localization must balance computational requirements and accuracy of localization. Increasing the number of particles in a particle filter improves accuracy, but also increases the computational requirements. Hence, we investigate a different paradigm to better utilize particles than to increase their numbers.

pH‐mediated activation of the lysosomal arginine sensor SLC38A9

FEBS Letters, EarlyView.
Cells monitor nutrient levels via the lysosomal transporter SLC38A9 to activate the mechanistic target of rapamycin complex 1 (mTORC1). This study reveals that SLC38A9 function is regulated by pH. We identified histidine 544 as a critical pH sensor that undergoes conformational changes to control amino acid efflux from lysosomes; therefore, it ...

A Comprehensive Method for Example-Based Color Transfer with Holistic–Local Balancing and Unit-Wise Riemannian Information Gradient Acceleration

Entropy
Color transfer, an essential technique in image editing, has recently received significant attention. However, achieving a balance between holistic color style transfer and local detail refinement remains a challenging task.
