“…The amorphous oxide semiconductor (AOS), indium gallium zinc oxide (IGZO) has also been demonstrated as active layer for memristors due to its great potential for 1T1M integration. [28][29][30][31][32][33][34][35][36] IGZO is often employed on TFTs in the display technology [37,38] as the semiconductor layer due to its excellent stability, cost-efficient manufacturing, and the additional control on its electrical conductivity provided by the oxygen and cation composition. [39] In fact, the development of neuromorphic displays is the unavoidable new trend for system-on-panel applications.…”

Memristor crossbar arrays can compose the efficient hardware for artificial intelligent applications. However, the requirements for a linear and symmetric synaptic weight update and low cycle‐to‐cycle (C2C) and device‐to‐device variability as well as the sneak‐path current issue have been delaying its further development. This study reports on a thin‐film amorphous oxide‐based 4×4 1‐transistor 1‐memristor (1T1M) crossbar. The a‐IGZO crossbar is built on a flexible polyimide substrate, enabling IoT and wearable applications. In the novel framework, the thin‐film transistor and memristor are fabricated at the same level, with the same processing steps and sharing the same materials for all layers. The 1T1M cells show linear and symmetrical plasticity characteristic with low C2C variability. The memristor performs like an analog dot product engine and vector–matrix multiplications in the 4×4 crossbars is demonstrated experimentally, in which the sneak‐path current issue is successfully suppressed, resulting in a proof‐of‐concept for a cost‐effective, flexible artificial neural networks hardware.

OBJECTIVES: This study investigated the prevalence, incidence, and prognosis of cardiac amyloidosis (CA) in Korea.METHODS: This retrospective nationwide population-based study used the Health Insurance Review and Assessment Service databases between 2008 and 2020. All patients diagnosed with amyloidosis were included, and those with a diagnosis of heart failure or cardiomyopathy were classified as having CA. Both the special code for amyloidosis (V121), which enables coverage of medical expenses, and the corresponding International Classification of Diseases, 10th revision codes for amyloidosis (E850- E854, E858, E859) were used to improve the reliability of amyloidosis diagnosis.RESULTS: Among 2,239 patients with amyloidosis, 758 met the criteria for CA (mean age, 64.4±11.9 years; 59.1% male). The mean age of patients with CA increased from 59.5±14.7 years in 2009 to 68.1±13.9 years in 2020. The incidence and prevalence increased from 0.09 (95% confidence interval [CI], 0.06 to 0.12) to 0.22 (95% CI, 0.18 to 0.27) per 100,000 person-years and 0.20 (95% CI, 0.16 to 0.25) to 1.30 (95% CI, 0.12 to 0.42) per 100,000 persons, respectively (all p<0.001). Patients with light-chain CA showed similar trends. In-hospital mortality decreased from 17.3% (95% CI, 9.23 to 29.6) to 6.10% (95% CI, 4.21 to 8.48) between 2009 and 2020. While age-specific in-hospital mortality was significantly higher in patients aged ≥70 years (p=0.004), no significant age-specific difference in in-hospital mortality was observed in patients with CA aged <70 years (p=0.981).CONCLUSIONS: The prevalence and incidence of CA have increased in Korea, predominantly affecting older individuals, particularly males. Notably, in-hospital mortality decreased significantly.
