Summary: In this study, subharmonic response of SonoVue microbubbles was observed in three stages, with the second growth stage showing the best correlation with ambient pressures. The results suggest that the subharmonic signals in the second growth stage may be suitable for estimating low ambient pressures.

Summary: This study investigated the structural and magnetic properties of Fe-based alloys with different Ge concentrations, finding that the addition of less than 20% Ge leads to preferred formation of alloys with a bcc-type structure. The lattice constant increases as the Ge concentration in the alloy increases. Additionally, all the alloys underwent a structural transformation from body-centred cubic to face-centred cubic structure at around 820K.

Summary: The microstructures and hydrogen absorption/desorption properties of V48Fe12Ti15+xCr25-x (x = 0, 5, 10, 15) alloys were comprehensively investigated. The alloys consisted of a primary BCC phase and a small amount of Laves and Ti-rich phases. The lattice constants of the BCC phase and the hydrogen absorption capacity of the alloys increased gradually with the increase of Ti contents. The diffusion of hydrogen atoms was found to be the rate limiting step in the process of hydrogen absorption/desorption. The diffusion coefficient of hydrogen atoms in the alloys increased with the increase of Ti/Cr atomic ratio.

Summary: There is ongoing debate about the influence of ideology in economics, but there is a lack of systematic empirical evidence on this issue. By conducting an online randomised controlled experiment with 2,425 economists in 19 countries, this study examines the effect of ideological bias among economists. The findings reveal the existence of ideological bias and authority bias among economists, with changes in source attributions affecting their reported agreement with statements.

Summary: This study found that during the extreme 2003 Halloween events, the ACE satellite observed Jovian periodicities at the Lagrangian Point L1 for at least three days, suggesting that low-energy Jovian electrons reached the Earth's environment. The ACE satellite also observed a series of energetic ion bursts with strong cross-field intensity gradients, indicating ion streaming in the anti-sunward direction. The observations suggest that these bursts were caused by the quasi-periodic approach of a large-scale sheet rather than a terrestrial origin.

Summary: Ibuprofen is a commonly used anti-inflammatory drug, but high concentrations of the drug detected in waterbodies can pose a risk to the environment and public health. This study investigated the photodegradation of ibuprofen using graphene quantum dots conjugated to porphyrin, and found that this combination had a high efficiency in degrading ibuprofen.

Summary: The study investigated the structure of 5,10,15,20-tetrakis(4-iodophenyl) porphyrin using chemical preparation, characterization, and crystal structure analysis combined with computational density functional theory. The molecular packing was found to be controlled by various molecular interactions and further discussed using hirshfeld surface analysis. Experimental and theoretical geometry confirmed the presence of a strong N-H center dot center dot center dot N intramolecular hydrogen bonding forming quasi-aromatic six-membered rings within the porphyrin core.

Summary: The study shows that neutron irradiation significantly enhances the spinodal decomposition in delta ferrite, while the dose rate and irradiation temperature have notable effects on the spinodal wavelength and amplitude. Lower irradiation temperature results in smaller G-phase precipitates, while a lower dose rate leads to larger G-phase precipitates in delta ferrite.

Summary: Cities worldwide aspire to become 10, 15, or 20-minute cities, aiming to reduce car dependence and promote sustainable and healthy urban design by encouraging walking and cycling. However, there is a lack of clear guidance on evaluating progress towards this goal. This paper compares measurement approaches and discusses key considerations for planners adopting the x-minute city goal.

Summary: The phototautomerism of free-base 5, 10, 15, 20-tetrakis(4-sulfonatophenyl) porphyrin (H2TPPS4-) in excited states was investigated using advanced Electron Paramagnetic Resonance (EPR) combined with fluorescence and Raman spectroscopy. Triplet EPR spectroscopy confirmed the occurrence of phototautomerization and the formation of the cis tautomer as a minor component. The results suggest a slow process in the triplet state and a model involving spin-vibronic coupling mechanism for intersystem crossing.

Summary: The current research on high entropy alloys (HEAs) focuses mainly on the influence of element composition and percentage difference on their corrosion resistance. However, there are obvious differences in the properties of the passive film formed by different element additions. Therefore, it is important to investigate the effect of the passive film on the corrosion behavior of HEAs.

Summary: This study investigated the influence of the (hafnium and zirconium)/molybdenum ratio on the microstructure and properties of Ti20Ta20Nb20(ZrHf)(20)Mo--x(x) (where: x = 0, 5, 10, 15, 20 at.%) high entropy alloys in an as-cast state. The results showed that the lattice parameters of the alloys decreased with increasing molybdenum concentration up to 10%, and then increased. Scanning and transmission electron microscopy confirmed the presence of a two-phase matrix microstructure and hafnium and zirconium precipitates. Mechanical property measurements revealed a decrease in hardness and Young's modulus up to 10% of Mo content, and then an increase up to 20% of molybdenum addition. Corrosion resistance measurements confirmed the high biomedical ability of the alloys.

Summary: This study investigated the metabolic responses to hypoxic breathing for 1 hour with inspired fractions of 10% and 15% oxygen. Blood samples were taken from 14 healthy nonsmoking volunteers before and at different time points after the hypoxic exposure. The study examined the levels of oxidative stress, antioxidant systems, and immune-inflammation markers. The findings provide insights into how acute hypoxia affects bodily functions and the protective mechanisms the body employs to maintain redox homeostasis in response to oxidative stress.

Summary: The plasma pharmacokinetics of acetaminophen following oral administration of a single dose of 20 or 40 mg/kg to neonatal foals were determined. The results showed that the plasma disposition of acetaminophen in neonatal foals is similar to adult horses. However, further research is needed to determine the safety and optimal dosage regimen for treating pain and fever in neonatal foals in this age group.

Summary: Burst-suppression pattern (BSP) is a distinctive EEG pattern associated with coma, epileptic encephalopathies, and induced by general anesthesia and hypothermia. Research has explored the correlation between depth of EEG suppression and improved seizure control and clinical outcomes. From a historical perspective, the evidence for suppressing the brain to a BSP when treating status epilepticus is inconclusive.

Summary: Guillain-Barre syndrome (GBS) is a neurological disorder characterized by acute, areflexic paralysis, often occurring after an immune stimulating event such as infection or surgery. GBS after spinal surgery is unusual and if there is an asymptomatic clinical interval before the onset of paralysis, it may suggest an immunological mechanism.
