Conventional gate-stack scaling reduces dielectric thickness and increases permittivity while largely treating the position and electronic character of the gate-side screening boundary as fixed. As equivalent oxide thickness is reduced, however, finite interfacial responses can increasingly constrain gate control [1-5].
Thermally Engineered Sodium-Embedded Alumina with Programmable Synaptic Plasticity for Neuromorphic Transistors
1 Introduction Due to the rapid development of artificial intelligence (AI), the demand for computing power is ever-growing. Although conventional von Neumann computing systems have supported AI development, the current architecture is subject to speed and energy efficiency limitations due to separation of the memory and processing units, which is known as the von Neumann bottleneck. To overcome this restriction, human-brain-inspired neuromorphic devices have been developed [1-5].

Integration of National Health Insurance claims data and animal models reveals fexofenadine as a promising repurposed drug for Parkinson’s disease - Journal of Neuroinflammation
Our study focused on patients diagnosed with PD after the age of 40 years between 2002 and 2020. We included patients who were prescribed either PD drugs (amantadine, benserazide, carbidopa, entacapone, levodopa, pramipexole, rasagiline, ropinirole, or selegiline) or antihistamines (azelastine, bepotastine, cetirizine, chlorpheniramine, clemastine, desloratadine, dimenhydrinate, ebastine, fexofenadine, hydroxyzine, ketotifen, levocetirizine, loratadine, mizolastine, or olopatadine).
Systemic sclerosis and risk of bronchiectasis: a nationwide longitudinal cohort study - Arthritis Research & Therapy
This study used a dataset provided by the Korean National Health Insurance Service (NHIS), a universal insurance provider managed by the government that covers 97% of the Korean population, approximately 50 million people.
Evaluation Of GPT-4 for 10-Year Cardiovascular Risk Prediction: Insights from the UK Biobank and KoGES Data
Background: Cardiovascular disease (CVD) is a leading global health concern. Accurate risk prediction is vital for prevention. Traditional models like the Framingham and ACC/AHA risk scores have been clinical mainstays. Recently, artificial intelligence (AI), specifically large language models (LLMs) like GPT-4, have shown promise in the medical field. However, their integration into medical practice is met with both potential and challenges due to reliability and reproducibility concerns.

Impact of air pollution on healthcare utilization in patients with bronchiectasis
Introduction Non-cystic fibrosis bronchiectasis (hereafter referred to as bronchiectasis) is a chronic lung disease characterized by abnormal and permanent dilation of bronchi and respiratory symptoms (1). Once considered an orphan disease, the prevalence and disease burden of bronchiectasis have also been increasing worldwide (2). In bronchiectasis management, prevention of exacerbation is key to reducing the disease burden (3).

Establishment of Immortalized Human Endometriotic Stromal Cell Line from Ectopic Lesion of a Patient with Endometriosis - Reproductive Sciences
Abstract Endometriosis is an estrogen-dependent inflammatory disease characterized by the growth of endometrial-like tissues containing endometrial stromal cells and glandular epithelium outside the uterine cavity. An insufficient response to progesterone contributes to disease progression and systemic inflammation during the pathogenesis of endometriosis.

Clinical characteristics of rheumatoid arthritis patients with interstitial lung disease: baseline data of a single-center prospective cohort - Arthritis Research & Therapy
Based on a multidisciplinary collaborative approach that was implemented according to a systematic protocol, we established a prospective cohort for RA-ILD patients. In the cross-sectional study which used the enrolment data of this prospective cohort, we demonstrated that higher age at RA diagnosis, a higher BMI, and smoking were associated with accompanying ILD in RA patients.

SHH and Notch regulate SOX9+ progenitors to govern arcuate POMC neurogenesis
Introduction Hypothalamic pro-opiomelanocortin (POMC)-expressing neurons in the arcuate nucleus (ARC) play key roles in regulating metabolism and body weight. POMC neurons respond to adipose-derived leptin by signalling to “satiety neurons” expressing the melanocortin receptor, ultimately inhibiting food intake and promoting energy expenditure (Lee and Blackshaw, 2014; Anderson et al., 2016; Quarta et al., 2020).
TNF inhibitors increase the risk of nontuberculous mycobacteria in patients with seropositive rheumatoid arthritis in a mycobacterium tuberculosis endemic area | Scientific Reports
Abstract The aim of this study is to examine the impact of tumor necrosis factor inhibitors (TNFI) on nontuberculous mycobacterium (NTM) infection in rheumatoid arthritis (RA) patients in a mycobacterium tuberculosis (MTB) endemic area. We selected 1089 TNFI-treated RA patients and 4356 untreated RA patients using propensity-matching analysis according to age, gender, and Charlson comorbidity index using the Korean National Health Insurance Service database from July 2009 to December 2010.
Author Correction: The cellular and molecular landscape of hypothalamic patterning and differentiation from embryonic to late postnatal development - Nature Communications
Correction to: Nature Communications https://doi.org/10.1038/s41467-020-18231-z, published online 31 August 2020. The original version of this Article contained an error in ‘Data analysis’, which incorrectly read: ‘For analysis of the entire hypothalamic dataset, Seurat v3.10 and Scanpy v1.5 were used to process matrix files to keep all cells with at least 200 detected genes’. The correct version adds ‘and 500 UMI’ after ‘200 detected genes’.
