Structural Basis of Lymphangiogenic Receptor VEGFR‐3 Activation Mediated by Distinctive Clustering of the Ligand–Receptor Complex

Advanced Science, EarlyView.
VEGF‐C and its receptor VEGFR‐3 are critical for lymphangiogenesis. Cryo‐EM structures of the VEGFR‐3/VEGF‐C ectodomain complex reveal a canonical 2:2 ligand–receptor hetero‐tetramer that further assembles into higher‐order clusters beyond simple receptor dimerization.

Real-time construction and visualisation of drift-free video mosaics from unconstrained camera motion

The Journal of Engineering, 2015
This work proposes a novel approach for real-time video mosaicking facilitating drift-free mosaic construction and visualisation, with integrated frame blending and redundancy management, that is shown to be flexible to a range of varying mosaic ...

DUET‐seq: An Open‐Source Droplet Platform for High‐Fidelity Joint Chromatin and Transcriptome Profiling Reveals Temporal Regulatory Decoupling in Single Cells

Advanced Science, EarlyView.
DUET‐seq is an open‐source droplet platform that jointly profiles chromatin accessibility and gene expression from the same nucleus. Dissolvable dual‐linker hydrogel beads and a one‐step intra‐droplet RT‐PCR co‐index both modalities in under 12 h at roughly $0.04 per cell.

LigHTS: Biomimetic Hydrogel Photo‐Fabrication for Imaging‐Based Ultra‐High‐Throughput Screening

Advanced Science, EarlyView.
LigHTS removes a key bottleneck for ultra‐high‐throughput screening (UHTS) by enabling biomimetic hydrogel microenvironments to be manufactured directly in standard multiwell plates. A single, collimated UV exposure with formulation‐tuned light penetration patterns an entire plate with UHTS‐grade uniformity (<20% CV), producing structured GelMA films ...

Complete Model for Automatic Object Detection and Localisation on Aerial Images using Convolutional Neural Networks

Journal of Communications Software and Systems, 2018
In this paper, a novel approach for an automatic object detection and localisation on aerial images is proposed. Proposed model does not use ground control points (GCPs) and consists of three major phases.

Automatic tiling method for mosaic ceramic art images based on subpixel edge fitting localization and collaborative operation of multiple manipulators

Scientific Reports
Mosaic ceramics are not limited to use solely as building materials, they also possess artistic value. Artists can create images by arranging and combining mosaic ceramics, resulting in a perfect fusion of large-scale public art for external walls and ...

Age‐Related Lamin B1 Deficiency Activates SLC7A11‐Dependent Disulfidptosis to Impair Osteogenesis via Intercepting Mitochondrial Fission

Advanced Science, EarlyView.
This study reveals that age‐related LMNB1 deficiency in mesenchymal stem cells epigenetically upregulates SLC7A11, triggering actin disulfidptosis and mitochondrial dysfunction. This cascade impairs bone formation in senile osteoporosis. Furthermore, researchers identified the FDA‐approved drug naldemedine as a targeted SLC7A11 inhibitor to reverse ...

Chiral‐Nematic Lattice Instability in Charge Density Wave of 1T‐TiSe2

Advanced Science, EarlyView.
The charge density wave of 1T‐TiSe2 appears chiral to surface probes yet loses all symmetry in spectroscopic measurements. This study reveals how cooperative condensation of multiple phonon modes stabilizes a chiral monoclinic ground state, while a shallow nematic energy landscape allows the lattice to break the remaining symmetry at negligible cost ...

Image Degradation by an Irregular Retinal Mosaic [PDF]

, 1977
In order to understand the significance of a regular photoreceptor mosaic we quantify the effect of deviations from regularity. Such deviations are shown to cause a deterioration in the quality of the image at the photoreceptor level because of image ...
