Abstract Bayesian networks (BNs) find widespread application in many real-world probabilistic problems including diagnostics, forecasting, computer vision, etc. The basic computing primitive for BNs is a stochastic bit (s-bit) generator that can control the probability of obtaining ‘1’ binary bit-stream. While silicon-based complementary metal-oxide-semiconductor (CMOS) technology be used hardware implementation BNs, lack inherent stochasticity makes it area and energy inefficient. On other...

Physically unclonable functions (PUFs) are an integral part of modern-day hardware security. Various types PUFs already exist, including optical, electronic, and magnetic PUFs. Here, we introduce a novel straintronic PUF (SPUF) by exploiting strain-induced reversible cracking in the contact microstructures graphene field-effect transistors (GFETs). We found that strain cycling GFETs with piezoelectric gate stack high-tensile-strength metal contacts can lead to abrupt transition some GFET...

Unisensory cues are often insufficient for animals to effectively engage in foraging, mating, and predatory activities. In contrast, integration of collected from multiple sensory organs enhances the overall perceptual experience thereby facilitates better decision-making. Despite importance multisensory animals, field artificial intelligence (AI) neuromorphic computing has primarily focused on processing unisensory information. This lack emphasis can be attributed absence a miniaturized...

Defects play a pivotal role in limiting the performance and reliability of nanoscale devices. Field-effect transistors (FETs) based on atomically thin two-dimensional (2D) semiconductors such as monolayer MoS2 are no exception. Probing defect dynamics 2D FETs is therefore significant interest. Here, we present comprehensive insight into various observed at varying gate biases temperatures. The measured source-to-drain currents exhibit random telegraph signals (RTS) owing to transfer charges...

Sepsis is common in intensive care units and has a high mortality rate; yet, its pathogenesis treatment remain unclear. Recent studies have shown that long non-coding RNA plasmacytoma variant translocation 1 (lncRNA-PVT1) plays pro-inflammatory role immune-related inflammatory diseases. Therefore, we investigated whether lncRNA-PVT1 an important effect the response of sepsis.Quantitative real-time PCR (RT-qPCR) was employed for detection lncRNA-PVT1, interleukin 1β (IL-1β), tumor necrosis...
