In this study, we explore the information capacity of open quantum systems, focusing on the effective channels formed by the subsystem of random quantum circuits and quantum Hamiltonian evolution. By analyzing the subsystem information capacity, which is closely linked to quantum coherent informatio...

Acute minor ischemic stroke (AMIS) patients may experience unfavorable outcomes despite mild initial symptoms. The ratio of red blood cell distribution width (RDW) to albumin (ALB) (RAR) has been associated with poor outcomes after stroke, but its role in AMIS remains unclear. This study aimed to in...

The correlation between aerodynamic data obtained from ground and flight tests is crucial in developing aerospace vehicles. This paper proposes methods for modelling this correlation that combine feature extraction and symbolic regression. The neighborhood component analysis (NCA) method is utilized...

Secondary wall-associated NAC domain protein1 (SND1) is a key regulator directly regulating the expression levels of MYB46 and MYB83 in the regulation network for secondary wall synthesis, especially in plant fibres. In this study, a SND1 gene was isolated from hawthorn (Crataegus pinnatifida) and n...

Soil aggregates are an important controlling factor for the physico-chemical and biological processes such as ammonium (NH4+) retention. Straw return to the field is increasingly recommended to promote soil carbon (C) sequestration and improve crop yields. However, the effects of straw return on NH4...

This paper presents a metasurface antenna with both radiation and scattering characteristics. First, a symmetric slotted patch antenna unit is designed and its operating frequency is tuned to the 8.4–9.4 GHz (11.2%) range. Subsequently, incorporating the principles of propagation phase, this study d...

Clinical chemotherapy for prostate cancer is still compromised by high treatment thresholds and severe off-target toxicity of drugs. Given the limited progress in improving therapeutic outcomes and reducing toxicity with the existing toolbox, efforts to broaden the chemotherapeutic window are highly...

Abstract Miniaturized spectrometers utilizing a single reconfigurable photodetector (PD) are highly attractive in the infrared (IR) range due to their advantages in terms of cost, ease of integration, and reduced system complexity. However, such devices usually suffer from either limited wavelength...
