Theories on evolution of cooperation assume that interacting individuals can change their strategies under different expected payoffs and cultural contexts. The willingness to invest resources into partners and to cooperate may therefore vary in collectivistic Eastern Asia as opposed to more individ...

Dynamic recrystallization (DRX) is a critical microstructural evolution mechanism in friction stir welding (FSW) of metallic materials, directly determining the mechanical properties and corrosion resistance of weld joints. In the field of DRX simulation, conventional models primarily consider intra...

Epidemics spread through shipping networks and have dual characteristics as both biological sources of infection and triggers of cascading failures. However, existing resilience models fail to capture this dual and coupled dynamics. To minimize the cascading impacts of epidemics on global shipping n...

Traumatic epidural hematoma is a common pathological condition following traumatic brain injury (TBI). Neurogenic pulmonary edema (NPE) is a rare but life-threatening complication, typically occurring in association with acute severe intracranial pathologies. Cases of pediatric traumatic epidural he...

Powder-bed-fusion (PBF) additive manufacturing of high-performance alloys (e.g. GH3536) necessitate stringent control of powder bed quality to mitigate defects, particularly cavities that compromise component integrity. By employing the Johnson-Kendall-Roberts (JKR) theoretical framework, this study...

COPD affects approximately 391 million people globally. While spirometry is recognized as the gold standard for diagnosing COPD according to the GOLD guidelines, its availability is limited in primary healthcare settings, particularly in low- and middle-income countries. Furthermore, spirometry requ...

Heat up hydrogels is one of the basic topics for hydrogel engineering. Existing efforts have focused on using external heat elements to heat up hydrogels by heat conduction, whereas the possibility of hydrogels to heat up directly by themselves has been ignored. Herein, we describe Joule heating of...

Static magnetic field (SMF) therapy, a non-ionizing and non-invasive treatment modality, has garnered increasing attention in glioma research. Gliomas, particularly glioblastoma (GBM), represent one of the most aggressive malignancies of the central nervous system, with limited therapeutic options a...

In recent years, heavy metal contamination in agricultural products has become a growing concern in the field of food safety. Copper (Cu) stress in crops not only leads to significant reductions in both yield and quality but also poses potential health risks to humans. This study proposes an efficie...

As an eco-efficient short-process manufacturing technique for aluminum alloys, twin-belt continuous casting and direct rolling (TBCCR) demonstrates significant production advantages. In this study, an Al-Fe-Si alloy system with different Fe-rich intermetallics (α-AlFe(Mn)Si and β-AlFe(Mn)Si) via TBC...

Novel bat influenza viruses show different features in contrast to classical influenza A viruses (IAVs). The M2 of IAVs functions as an ion channel that plays an important role in virus entry, viral assembly, and release and also serves as the antiviral target. To date, whether bat influenza M2 func...

This retrospective study aimed to assess the effectiveness of prophylactic hepatoprotective therapy in decreasing the incidence of drug-induced liver injury (DILI) among patients with cervical cancer undergoing chemotherapy. The analysis was performed on patients with cervical cancer who received ch...
