People Counting and Positioning Using Low‐Resolution Infrared Images for FeFET‐Based In‐Memory Computing

Advanced Electronic Materials, EarlyView.
In this work, low‐resolution infrared imaging is combined with a 28 nm FeFET IMC architecture to enable compact, energy‐efficient edge inference. MLC FeFET devices are experimentally characterized, and controlled multi‐level current accumulation is validated at crossbar array level.

The neurological underpinnings of cluttering: Some initial findings [PDF]

, 2015
Background Cluttering is a fluency disorder characterised by overly rapid or jerky speech patterns that compromise intelligibility. The neural correlates of cluttering are unknown but theoretical accounts implicate the basal ganglia and medial ...

Improved MobileViT Algorithm for Rail-Defect Recognition Incorporating Image-Quality Pre-Assessment

Applied Sciences
UAV-based rail inspection is hampered by minute-defect detection, background clutter, and edge-computing constraints. To address these issues, this paper proposes a lightweight rail-defect recognition model based on improved MobileViT.

Coupling Exponential Rolling Circle Amplification to Lateral Flow Devices for Point‐of‐Care Detection of Viral RNA

Angewandte Chemie, EarlyView.
A new exponential RCA (E‐RCA) system was developed and coupled to a toehold system for release of a bridging DNA, allowing for lateral flow detection. The E‐RCA method uses a secondary primer (P2) that binds RCA products (RCAP) to generate extended P2 products that can re‐prime a partially self‐complementary circular template, generating a complete ...

Spectral–Spatial Synergistic Learning and Context-Aware Edge Enhancement for Efficient Oriented Object Detection in SAR Images

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
Oriented object detection in synthetic aperture radar (SAR) imagery remains challenging because speckle noise, blurred target boundaries, strong clutter, and large-aspect-ratio objects often degrade localization accuracy and increase false alarms ...

Real‐Time Multicolor Fluorescence Microscopy via Cross‐Channel Acquisition and Deep‐Learning‐Based Inference

Advanced Intelligent Discovery, EarlyView.
Sequential multicolor fluorescence imaging in dynamic microsystems is constrained by acquisition speed and excitation dose. This study introduces a real‐time framework to reconstruct spectrally separated channels from reduced cross‐channel acquisitions (frames containing mixed spectral contributions).

Feature Congestion and Subband Entropy measures of visual clutter

, 2007
This MATLAB software implements two measures of visual clutter described in our Journal of Vision 2007 paper in the special issue on crowding. The remaining measure described in that paper, Edge Density, is only two lines of MATLAB code and is fully ...

A Conserved Isoleucine Gates the Diffusion of CO and O2 to the Active Site of NiFe CO‐Dehydrogenase

Angewandte Chemie, EarlyView.
A combination of protein film electrochemistry and site‐directed mutagenesis shows that isoleucine 563 (numbering of Thermococcus sp. AM4) gates the arrival of both CO and O2 to the active site of the nickel‐iron CO dehydrogenases. Mutations at this position increase the resistance to O2 at the cost of a slower reaction with CO.

3D Object Modeling and Segmentation Using Image Edge Points in Cluttered Environments

Journal of Robotics and Mechatronics, 2009
Object models are indispensable for robots to recognize objects when conducting tasks. This paper proposes a method of creating object models from images captured in real environments using a monocular camera. In our framework, an object model consists of a 3D model composed of 3D points reconstructed from image edge points and 2D models composed of ...
