Bilayer graphene as a prototype of two-dimensional stacked material has recently attracted great attention. The twist angle between graphene layers adds another dimension to control its properties. In this study, we used Raman mapping to investigate the twist angle dependence of properties of twiste...

Nipah virus (NiV), a bat-borne paramyxovirus, results in neurological and respiratory diseases with high mortality in humans and animals. Developing vaccines is crucial for fighting these diseases. Previously, only a few studies focused on the fusion (F) protein alone as the immunogen. Numerous NiV ...

Since the ‘first green revolution’ in the 1960s, rice grain yield has risen sharply. However, due to the continual decreasing of cropping areas, further increase in yield potentials is urgently demanding. Long-term excessive fertilization has led to uncontrolled retention of nitrogen fertilizer in t...

The Nipah virus (NiV), a highly deadly bat-borne paramyxovirus, poses a substantial threat due to recurrent outbreaks in specific regions, causing severe respiratory and neurological diseases with high morbidity. Two distinct strains, NiV-Malaysia (NiV-M) and NiV-Bangladesh (NiV-B), contribute to ou...

Wide voltage range circuit has got widespread attention where in-situ timing monitoring based adaptive voltage scaling (AVS) becomes necessary to reduce the design margin. However, the severe PVT variations across near-threshold to super-threshold cause too many critical paths to be monitored. Here ...

S-box is a core component of many block cipher algorithms. A reconfigurable S-box based on look-up table (LUT) with memory-sharing is proposed in this paper. It uses a sharing memory to support different S-box operation modes (4 × 4, 6 × 4, and 8 × 8) for most of the block cipher algorithms as well ...

In the current Dynamic voltage scaling (DVS) integrated circuits, sufficient timing and voltage margins are typically wasted, because it is difficult to anticipate the exact amount by which the voltage or frequency should be scaled. The on-chip timing monitoring method is effective for this problem....

An all-digital circuit for on-chip measuring the long-term jitter of Phase-Locked Loop (PLL) using the undersampling technique is presented in this paper. The circuit comprises the undersampling circuit, which samples the PLL output signal and the data analysis circuit, which calculates the statisti...

In this brief paper, both static and dynamic behaviors of an electrostatic-actuated MEMS mirror are modeled and studied. To overcome the intrinsic pull-in problem and the dynamic disadvantages in the open-loop controlled actuation, a novel closed-loop feedback control method is proposed assuming the...

Diffusion models demonstrate superior performance in capturing complex distributions from large-scale datasets, providing a promising solution for quadrupedal locomotion control. However, the robustness of the diffusion planner is inherently dependent on the diversity of the pre-collected datasets. ...

We propose an energy-efficient large fan-in one-hot dynamic logic multiplexer (OHDL-MUX) for the design of low-power large-scale digital integrated circuits. It is composed of a specific pulse generator, dynamic AND-OR cells and a dynamic OR cell. Conventionally, a large fan-in CMOS MUX is composed ...

In order to eliminate the excess timing margin in integrated circuit due to PVT variations, we propose a low overhead timing error prediction monitor, which has only 14 transistors with negligible power overhead. It can generate a predicted alarm signal when the timing is intense before real errors ...

It is becoming common to implement power switches in low power system-on-chip (SoC). However, the power switches are not tested for manufactory defects in most designs currently. In this letter, a novel built-in self test (BIST) solution for power switch is proposed. The proposed solution can test t...

Atmospheric oxygenated organic molecules (OOMs) are key intermediates driving secondary organic aerosol (SOA) formation and new particle growth, yet their molecular-level characterization is constrained by the insufficient mass resolution of current online mass spectrometers (MS). Here, we developed...

Large Language Models (LLMs) is widely used for code debugging (e.g., C and Python) but face limitations in debugging Register Transfer Level (RTL) code largely due to data scarcity. This paper presents Make Each Iteration Count (MEIC), a novel framework for RTL debugging. Unlike traditional approac...
