Purification of Disassembled Capsid Protein by Hydroxyapatite Chromatography Enhances Virus‐Like Particle Recovery

Biotechnology and Bioengineering, EarlyView.
ABSTRACT Virus‐like particles (VLPs) are a promising modality with extensive applications in prophylactic and therapeutic vaccine design. Human Papillomavirus (HPV) vaccines are one such example where VLP vaccine applications have led to the successful reduction in HPV‐associated diseases, such as cervical cancer.

Inertial Sensor-Assisted High-Coverage Visible Light Positioning Algorithm

IEEE Photonics Journal
Existing visible light positioning (VLP) algorithms typically require multiple LEDs to achieve high-precision positioning. However, in practice, the number of available LEDs is influenced by various factors such as the layout of LEDs and the field-of ...

Characterization of Immune Responses to RBD‐SD1 Nanoparticle Vaccines Derived From ACE2‐Capable HKU5‐CoV‐2, NeoCoV, and HKU5 Merbecoviruses

Biotechnology and Bioengineering, EarlyView.
SpyCatcher‐mi3 nanoparticles presenting HKU5, NeoCoV, and HKU5‐CoV‐2 RBD‐SD1 induced strong, cross‐reactive IgG responses in immunized mice. The surrogate virus neutralization test demonstrated strong activity in sera from homologous vaccination. ABSTRACT Recent discoveries of merbecoviruses such as HKU5, NeoCoV, and HKU5‐CoV‐2 that use angiotensin ...

Fluid‐induced slip on a rate‐and‐state fault during co‐ and post‐injection: The interplay of fluid pressure diffusion and poroelastic stress

Deep Underground Science and Engineering, EarlyView.
Fault slip can occur ahead of the injection pressure front due to poroelastic stress. Our model captures the interaction of pressure, stress, and friction, providing new insights into injection‐induced seismicity and post‐injection fault slip. Shut‐in operations can either mitigate or accelerate seismic events depending on fault conditions and ...

An Indoor Visible Light Positioning System Using Tilted LEDs with High Accuracy [PDF]

, 2021
The accuracy of the received signal strength-based visible light positioning (VLP) system in indoor applications is constrained by the tilt angles of transmitters (Txs) and receivers as well as multipath reflections. In this paper, for the first time, we

Indoor 3-Dimensional Visible Light Positioning Based on Smartphone Camera: Error Metric and LED Layout Optimization

IEEE Photonics Journal, 2022
We consider 3-dimensional (3D) visible light positioning (VLP) based on smartphone camera in an indoor scenario. Based on the positioning model in the quantized pixel-domain, we characterize the 3D normalized positioning error metric (NPEM) through the ...

A Comparison of Mobile Laser Scanning Data Acquisition Methods in Closed Forest, Open Woodland and Sub‐Alpine Woodland Ecosystems

Remote Sensing in Ecology and Conservation, EarlyView.
This study demonstrates that the mobile laser scanning (MLS) sampling density required to reliably characterise vegetation structure increases with a site's structural complexity. Applying a five‐level acquisition framework across open woodland, closed forest and sub‐alpine woodland ecosystems, we found that longer scanning paths increased the ...
