Low Complexity Keystone Transform and Radon Fourier Transform Utilizing Chirp-Z Transform

IEEE Access, 2020
Keystone Transform (KT) and Radon Fourier Transform (RFT) are two popular methods proposed to overcome range migration in radars. A major concern in these methods is the computational complexity for real time operations.

Nonreciprocal Swarmalators With Reconfigurable and Controllable Formations for Robot Collectives

Advanced Robotics Research, EarlyView.
Nonreciprocal swarmalator interactions are enabled through control barrier functions to transform self‐organizing robot collectives into reconfigurable, constraint‐aware systems. Complex two‐ and three‐dimensional shapes, continuous morphing, obstacle‐aware navigation, collective splitting, and object transport emerge from modulating agent‐level ...

CREAT: A CRISPR‐Based Genome Trimming Strategy for Systematic Identification of Dispensable Regions and Rapid Genome Reduction

Advanced Science, EarlyView.
Current genome‐reduction methods work in a trial‐and‐error fashion, constituting a long‐standing bottleneck in the research. We developed CREAT (CRISPR‐based genome trimming with a multi‐homology‐arm template), a CRISPR‐based genetic approach that enables systematically classifying essential versus non‐essential genomic regions and subsequently ...

Holography on local fields via Radon transform

Journal of High Energy Physics, 2018
We define Radon transform and its inverse on the two-dimensional anti-de Sitter space over local fields using a novel construction through a quadratic equation over the local field.

Adipocyte Myoglobin Is a Determinant of Energy Expenditure and a Potential Target to Limit Obesity

Advanced Science, EarlyView.
Myoglobin, known as a muscle oxygen‐carrying protein, is shown to play a key role in fat cells that burn energy. Loss of myoglobin reduces the body's ability to generate heat and increases obesity risk, while restoring it improves metabolism. The study identifies myoglobin as a regulator of fat burning and a potential target to enhance energy ...

Biomimetic Hydrogel System Targeting S100A8 Centered Neuroimmune Crosstalk and Hypoxia Induced Neuronal Injury

Advanced Science, EarlyView.
A biomimetic hydrogel (HPC@Gel) was developed for traumatic brain injury repair by combining oxygen‐carrying hemoglobin nanoparticles and anti‐inflammatory carbon quantum dots within a brain‐like matrix. The system alleviated hypoxia, reduced harmful neuroimmune signaling, protected neurons, supported neural regeneration, and improved neurological and ...
