Conceptual Design and Demonstration of Space Scale for Measuring Mass in Microgravity Environment [PDF]

open access: yesJournal of Astronomy and Space Sciences, 2015
In this study, a new idea for developing a space scale for measuring mass in a microgravity environment was proposed by using the inertial force properties of an object to measure its mass.

Scale Spaces on Lie Groups [PDF]

open access: yes, 2007
In the standard scale space approach one obtains a scale space representation u:R of an image by means of an evolution equation on the additive group (R d ,¿+¿). However, it is common to apply a wavelet transform (constructed via a representation of a Lie-group G and admissible wavelet ¿) to an image which provides a detailed overview of the group ...

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

open access: yesFEBS 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.

Dynamic texture recognition using time-causal spatio-temporal scale-space filters [PDF]

open access: yes, 2017
This work presents an evaluation of using time-causal scale-space filters as primitives for video analysis. For this purpose, we present a new family of video descriptors based on regional statistics of spatiotemporal scale-space filter responses and ...

Improvement of Harris Algorithm Based on Gaussian Scale Space [PDF]

open access: yesEngineering and Technology Journal, 2019
Features is the description of the image contents which could be corner, blob or edge. Corners are one of the most important feature to describe image, therefore there are many algorithms to detect corners such as Harris, FAST, SUSAN, etc.

Geometric moments in scale-spaces

open access: yesObject recognition supported by user interaction for service robots, 2003
We present a generalization of geometric moments in scale-spaces derived from the general heat diffusion equation, with a particular interest in minimax flow. As an application of those theoretical developments, two multiscale moments are used to enhance the classical Euclidean registration process.

Diversity and complexity in neural organoids

open access: yesFEBS Letters, EarlyView.
Neural organoid research aims to expand genetic diversity on one side and increase tissue complexity on the other. Chimeroids integrate multiple donor genomes within single organoids. Self‐organising multi‐identity organoids, exogenous cell seeding, or enforced assembly of region‐specific organoids contribute to tissue complexity.

A high-resolution lithospheric magnetic field model of China and surroundings by using CHAMP, Swarm, CSES-1, and MSS-1 satellite magnetic measurements and aeromagnetic anomaly data

open access: yesEarth and Planetary Physics
The CUG_CLMFM3D series comprises high-resolution three-dimensional lithospheric magnetic field models for China and its surroundings. The first version, CUG_CLMFM3Dv1, is a spherical cap harmonic model integrating the WDMAMv2 (World Digital Magnetic ...

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

open access: yesFEBS 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 ...

A cubed-sphere based method for global and regional modeling of the lithospheric magnetic field

open access: yesEarth and Planetary Physics
The Earth’s magnetic field, which has been extensively observed from ground to satellite altitudes over several decades, originates from multiple sources, such as the core dynamo, the conductive mantle, the magnetized lithosphere, and the space current ...
