Route planning under uncertain traffic conditions requires accounting for not only expected travel times but also the risk of late arrivals. This study proposes a mean-upper partial moment (MUPM) framework for pathfinding that explicitly considers travel time unreliability. The framework incorporate...

BackgroundColorectal cancer (CRC) remains a major global health burden, particularly when complicated by pulmonary metastasis (PM), which significantly worsens prognosis and reduces survival despite active treatment. The absence of standardized therapeutic strategies for CRC with PM has driven resea...

<i>Background</i>: The Irish government has put forth sustainable transport policy measures, yet the emphasis is mainly on the active travel and sustainable mobility for passenger transport. Contrariwise, freight transport has not received equal consideration in policy measures, regulato...

Rapid advancements in ML have strongly boosted SAR research. Yet, ML applications in this field are constrained by the limited availability of valid SAR benchmark datasets. To address this gap, this paper proposes a standard framework for creating those. We introduce three categories for extracting...

In wind power DC transmission systems, commutation failures cause significant reactive power fluctuations at the direct current (DC) transmission end, leading to sequential changes in voltage from low to high and often causing wind turbines to disconnect during low- to high-voltage cascading faults....

IntroductionFacet joint violation (FJV) is a common complication of intervertebral fusion surgery, altering the load-bearing capability of the facet joints and ultimately contributing to segmental instability. Furthermore, adjacent segment degeneration is one of the potential long-term complications...

Rigid polyurethane foam (RPUF) had been widely used in many fields due to its excellent performance. However, its poor thermal stability had invisibly formed a certain obstacle to its further development, so it was imperative to improve its thermal stability and other properties. In the current work...

BackgroundFusarium infections are rare but life-threatening in immunocompromised patients, particularly those with acute lymphoblastic leukemia (ALL) undergoing chemotherapy. This case report describes a patient with ALL who developed multifocal cutaneous Fusarium solani infections following VDCLP c...

AlON-C (∼25 μm) powders were prepared using the carbothermal reduction and nitridation (CRN) method. The powders were subsequently processed through milling to obtain AlON-M (∼1.6 μm) and AlON-F (∼456 nm). The experimental results indicated that both AlON-M and AlON-F underwent hydrolysis to form Al...

The quality of wine largely depends on the quality of wine grapes, which is determined by their chemical composition. Therefore, measuring parameters related to grape ripeness, such as soluble solids content (SSC), is crucial for harvesting high-quality grapes. Visible–Near-Infrared (Vis/NIR) spectr...

Abstract As urban traffic complexity continues to rise, challenges related to traffic efficiency, fuel consumption, and safety are becoming increasingly critical. These issues underline the need for multi-objective trajectory optimization models, particularly in environments where both automated and...

Background: The aim of this study was to introduce and to evaluate the functional results of volar plating of distal radial fractures through a longitudinal minimally invasive approach. Methods: From January 2010 to January 2013, 157 patients with distal radial fractures were randomly allocated to g...

The use of the vertical shaft sinking machine (VSM) for shaft construction can effectively improve construction safety and efficiency. This study focused on analyzing the internal forces and deformation characteristics of a 50.3 m deep shaft constructed by the VSM method. Findings reveal that the ex...

The anhydride-cured epoxy resin with silica micro-powder (SAE) is widely used in electrical equipment due to its excellent properties. However, its three-dimensional network structure makes degradation and recycling difficult. Conventional disposal methods, such as incineration or landfill waste res...

Simultaneous Localization and Mapping (SLAM) remains challenging in dynamic environments. Recent approaches combining deep learning with algorithms for dynamic scenes comprise two types: faster, less accurate object detection-based methods and highly accurate, computationally costly instance segment...
