Summary: A specifically designed molecule functions as a digital full adder on a gold surface, with 3 inputs and 2 outputs. By interacting with aluminum atoms, classical digits are converted to quantum information, eliminating the need for a solid-state digital full adder cascade-like architecture. The results are influenced by quantum level repulsion and nonlinear magnetic effects intrinsic to the molecule.

Summary: Liveness detection is widely used in face authentication systems to prevent malicious attacks. However, current methods relying solely on visual frames are vulnerable when visual perception is unreliable. To address this challenge, SonarGuard combines ultrasonic and visual information to achieve robust liveness detection on mobile devices, extracting micro-doppler signatures and motion trajectories from ultrasound reflections and video frames, respectively. Experimental results show that SonarGuard can significantly improve the security of face authentication systems in real-world usage without hardware modification.

Summary: This study demonstrates the potential of photonic in-memory computing by using a tantalum pentoxide-based memristor as a non-volatile memory. The controllable transition from write-once-read-many-times (WORM) memory to resistive random-access memory (RRAM) is achieved by changing the depositional sequence. In situ photonic Boolean logic operations (AND/OR) are achieved in the RRAM device by combining light and electric signals, showing superior photonic in-memory computing potential.

Summary: Researchers are investigating memristors to emulate synapse or in-memory computing in order to meet the exponentially increased demand for data processing. They investigated the impact of oxygen content on storage and synaptic performances in Ag/Ta (x) O (y) /ITO memristors to further enhance its performance. By optimizing the oxygen content, the synaptic weight modulation ability increased almost sevenfold. The work lays the foundation for optimizing memory storage and neuromorphic performances in future in-memory computing.
