High precision measurement of visibility has wide applications in the fields of civil aviation and maritime transportation. However, for a long time, the non-uniform of the atmosphere and optical contamination under low visibility have always been important issues affecting the measurement accuracy...

Urban air mobility (UAM) represents a transformative approach to alleviating ground-level congestion by transitioning from two-dimension (2D) to three-dimension (3D) transportation systems. Envisioned as a safe, sustainable, and efficient mode of urban transit, UAM leverages aerial space to reduce d...

Blended learning has emerged as a popular trend in education; however, as students from higher vocational colleges who are often in the lower 50% of national standardized entrance exam achievers, their teachers face unique challenges in implementing blended learning. This study summarized effective...

Full waveform inversion (FWI) is an established precise velocity estimation tool for seismic exploration. Machine learning-based FWI could plausibly circumvent the long-standing cycle-skipping problem of traditional model-driven methods. The physics-guided self-supervised FWI is appealing in that it...

This study examines the impact of cash crop cultivation on household income and migration decisions, using survey data collected from low-income regions in China. Given farmers decide themselves whether to cultivate cash crops, an endogenous treatment regression model that accounts for potential sel...

Multimodal transportation systems significantly enhance travel convenience but also introduce vulnerabilities. Disruptions in one segment can cascade across the network, compromising overall network performance. These disruptions, often stemming from diverse attack scenarios, highlight the critical...

In this paper, we report our numerical investigation on the photoionization of hydrogen by two orthogonal elliptically polarized and time-delayed attosecond pulses; we found that the momentum distributions exhibit a helical structure. The spectral patterns were obtained by making the use of the stro...

In this paper, we report the results of numerical simulation on vortex-shaped photoelectron momentum spectra of the hydrogen atom irradiated by a pair of time-delayed circularly polarized ultrashort pulses. Spectral alterations including broadening, splitting, and fusion are observed with stronger p...

For improving the performance of intrusion discrimination in the dual Mach-zehnder interferometric (DMZI) perimeter system, we propose a novel method based upon local mean decomposition (LMD), independent component analysis (ICA) and features combination. By the LMD-ICA, the original signal is proce...

Accurate carbon price forecasting is essential for market stability, risk management, and policy-making. To address the nonlinear, non-stationary, and multiscale nature of carbon prices, this paper proposes a forecasting framework integrating secondary decomposition, two-stage feature selection, and...

The neurotoxic effects of cis-bifenthrin (cis-BF) on amphibians and its molecular mechanisms are unclear despite its common presence in aquatic environments. In present study, female Xenopus laevis were subjected to a three-month treatment with environmentally relevant concentrations of 60 and 300 n...

BackgroundDiabetic foot (DF) is a common complication among people with diabetes, typically caused by peripheral neuropathy (PN) and/or peripheral arterial disease (PAD) of the lower limbs. The existing research mainly focuses on cases of diabetic foot ulcers, while the relationship between at-risk...

BackgroundBreast cancer is a major threat to women’s health, and dysregulation of the cell cycle is a critical driver of its progression. ESCO2, a potential key regulator of the cell cycle, is implicated in cancer development; however, its specific role and mechanisms in breast cancer remain poorly...
