Situated in close proximity to the Korea Peninsula and the Japan Islands, Shandong Province in China (SDP) has emerged as a focal point for global attention due to its significant surface ozone (O ) and aerosol pollution. Despite this attention, there are notable gaps in knowledge across various interconnected research domains, encompassing climate change, atmospheric circulation, anthropogenic emissions, and the chemistry of O and aerosols. The impact of frequent heat waves on regional O and aerosol pollution remains unclear, while our comprehension of atmospheric circulation dynamics and the chemistry involved with O and aerosols is still hampered by substantial limitations. The unique topography and geographical setting of SDP, with its complex interplay of factors like sea–land breezes, mountain–valley winds, and urban heat islands, make it an ideal location for investigating the dynamics of O and aerosol chemistry. Moreover, it is essential to explore the effects of transboundary transport on O and aerosol pollution and delve into the underlying mechanisms contributing to their combined pollution effects. To bridge these knowledge gaps, the Innovative Collaboration-Based Ozone and Aerosol Observation Network in Northeast Asia has been established through collaborative efforts involving the Bureaus of Ecology and Environment, Meteorology in SDP, and the Chinese Academy of Sciences. This network encompasses various components, including air quality and weather stations, a network of low-cost air quality sensors, monitoring stations focused on atmospheric photochemical smog and aerosol chemical speciation, and vertical measurement systems targeting O and its precursor gases (utilizing light detection and ranging, balloon sounding, and drone-based measurements), as well as measurements conducted via vehicles and ships. Additionally, preliminary findings from this comprehensive observational campaign will be shared.

Aims This study aimed to explore the correlation between radiomics features of pericoronary adipose tissue (PCAT) and gene expression in patients with coronary artery disease (CAD), with the goal of identifying novel imaging biomarkers for evaluating CAD.

Background Pulmonary hypertension (PH) is a malignant vascular disease characterized by pulmonary arterial remodeling. Neural cell adhesion molecule 1 (NCAM1) is a cell surface glycoprotein that is involved in a variety of diseases, including cardiovascular disease. However, the role of NCAM1 in PH remains underexplored.

Nagaoka ferromagnetism (NF) is a long-predicted example of itinerant ferromagnetism (IF) in the Hubbard model that has been studied theoretically for many years. The condition for NF, an infinite on-site Coulomb repulsion and a single hole in a half-filled band, does not arise naturally in materials. NF was only realized recently for the first time in experiments on a 2 × 2array of gated quantum dots. Dopant arrays and gated quantum dots in Si allow for engineering controllable systems with complex geometries. This makes dopant and quantum dot arrays good candidates to study NF in different array geometries through analog quantum simulation. Here we present theoretical simulations done for arrays and larger arrays and predict the emergence of different forms of ferromagnetism in different geometries. We find NF in perfect arrays, as well as in arrays for one hole doping of a half-filled band. The ratio of the hopping to Hubbard on-site repulsion that defines the onset of NF scales as as increases, approaching the bulk limit of infinite for large. Additional simulations are done for geometries made by removing sites from arrays. Different forms of ferromagnetism are found for different geometries. Loops show ferromagnetism, but only for three electrons. For loops, the critical for the onset of ferromagnetism scales as as the loop length increases. We show that the different dependencies on size for loops and arrays can be understood by scaling arguments that highlight the different energy contributions to each different form of ferromagnetism. Our results show how analog quantum simulation with small arrays can elucidate the role of effects including wave-function connectivity; system geometry, size, and symmetry; bulk and edge sites; and kinetic energy in determining quantum magnetism of small systems.

In the present analysis, we investigated the association between alcohol consumption and ambulatory blood pressure (BP) control in male patients after 8 weeks of antihypertensive therapy with two dihydropyridine calcium channel blockers. The study participants were hypertensive (clinic systolic/diastolic BP of 140-179/90-109 mmHg and 24-hour ambulatory systolic/diastolic BP ≥ 130/80 mmHg) patients enrolled in a randomized controlled trial and treated with amlodipine 5–10 mg or nifedipine gastrointestinal therapeutic system (GITS) 30–60 mg once daily. Alcohol consumption was classified as non-drinkers and drinkers. Non-dipping was defined as a BP drop from daytime to nighttime <10%. At baseline, the 131 alcohol drinkers, compared with 141 non-drinkers, had a significantly higher nighttime systolic/diastolic BP (129.3 ± 13.5/83.8 ± 9.5 vs. 125.7 ± 12.3/80.9 ± 8.2 mmHg, P ≤ 0.02), night-to-day ratio for both systolic (89.1 ± 8.5 vs. 87.0 ± 7.1%, P = 0.03) and diastolic BP (88.7 ± 8.8
