A Switched-Coupled-Inductor Quasi-Z-Source Network With High Boost Capability

IEEE Access
This paper proposes a new high gain quasi-Z-source network (qZSN) using a two-winding switched-coupled-inductor (SCL). By employing a two-winding SCL within the impedance network, the proposed topology offers high boost capability at low shoot-through ...

Topology‐Driven X‐Shaped DNA as a cGAS Stimulator to Promote Dendritic Cell Activation and Antitumor Vaccine Efficacy

Advanced Science, EarlyView.
X‐shaped DNA promotes multivalent cGAS assembly and enhances cGAS‐STING signaling. When conjugated with antigenic peptides, the resulting X‐DNA‐based peptide vaccine promotes dendritic cell activation, antigen presentation, and antitumor T‐cell responses.

Interface‐Mediated Self‐Rectifying CsCuCl3 Memristors With Tunable Thresholds for Reconfigurable Neuromorphic Computing

Advanced Science, EarlyView.
Interface‐mediated CsCuCl3 memristors achieve self‐rectification and tunable thresholds, enabling selector‐free 8 × 8 arrays with > 105 ON/OFF and > 104 rectification. Supporting dual‐mode neuromorphic computing, negative thresholds preserve low‐light recognition accuracy (91%), while positive thresholds enable sparsity‐aware edge computing.

Model‐Based Time‐Modulated Write Algorithm for 1R Analog Memristive Crossbar Arrays

Advanced Electronic Materials, EarlyView.
A novel model‐based time‐modulated write algorithm efficiently programs analog 1R memristive crossbar arrays by varying pulse duration at a fixed voltage. By leveraging a physics‐based compact model and a dynamic gain mechanism, this approach overcomes device nonlinearities and parasitic effects.

Al1−xHfxN$\text{Al$_{1-x}$Hf$_{x}$N}$ Thin Films with Enhanced Piezoelectric Responses for GHz Surface Acoustic Wave Devices

Advanced Electronic Materials, EarlyView.
Reactively sputtered wurtzite Al1‐xHfxN thin films, exhibiting strong c‐axis texture and enhanced piezoelectric response, are demonstrated as a cost‐effective alternative to Al1‐xScxN. X‐ray absorption spectroscopy reveals that cross‐gap N 2p–Hf 5d hybridization increases the Born effective charge and enables a multifold increase in piezoelectric ...

Improved switched-inductor quasi-switched-boost inverter with low input current ripple

2015 56th International Scientific Conference on Power and Electrical Engineering of Riga Technical University (RTUCON), 2015
The quasi-switched-boost inverter is an alternative to the quasi-Z-Source inverter. Its passive component number is two times smaller but it contains two additional semiconductor components. Earlier the switched-inductor cell was applied in this topology to enhance dc voltage gain at the cost of high input current ripple.

Exploiting Temperature Effects for Robust Control and Reference Circuits Using Thin‐Film Contact‐Controlled Transistors

Advanced Electronic Materials, EarlyView.
Compact circuits based on contact‐controlled transistors are well‐suited to unsupervised thermal management, sensitive temperature measurement, or temperature‐stable current references. Demonstrated on flexible microcrystalline silicon and supported by simulation, the approach does not require supply voltage regulation, remains manufacturable across ...
