Epidemiological trends and age-period-cohort effects on subarachnoid hemorrhage burden across the BRICS-plus from 1992 to 2021
Published 2025-07-01“…A significant negative correlation was observed between the incidence rate of SAH and SDI values. Nations displayed similar age-effect patterns characterized by initial declines followed by subsequent increases with advancing age, along with distinct period and cohort effects that may reflect variations in control measures and temporal burden patterns.ConclusionOur study demonstrates the overall decline in age standardized incidence rate of SAH, while highlighting the persistent health inequalities among eleven countries potentially attributable to socioeconomic disparities. …”

ESTIMATION OF THE ASYMMETRIC VERTICAL VARIATION OF THE SOUTHERN AND NORTHERN HEMISPHERES OF THE EARTH
Published 2015-09-01“…Transformation between the velocity fields under ITRF2008 and ITRF2000 can explain why different authors have different conclusions about the expansion/compression pattern of one hemisphere or the other. Anyway, the entire Earth is expanding at a rate about 0.2 mm/yr, and this estimation coincides with results of our previous studies. …”

Using linked data to explore medical complications associated with Robson classification of cesarean deliveries in Massachusetts, 2011 to 2018AJOG Global Reports at a Glance
Published 2025-05-01“…Almost all births for malpresentation or malposition of fetus had at least one labor and delivery complication but much lower rates of risk factors (between 25% and 46%). Conclusion: While cesarean delivery rates, maternal risk factors, and labor and delivery complications followed similar patterns across Robson groups, there were notable discrepancies, especially in births with noncephalic presentations where maternal comorbidity rates matched lower cesarean-risk groups like the nulliparous single-term cephalic births.…”

Study on the propagation law of hydraulic fractures in heterogeneous permeability reservoirs.
Published 2025-01-01“…The impacts of permeability heterogeneous, injection rate, and fracturing fluid viscosity on fracture morphology are systematically investigated, and the elasticity coefficient method was used to evaluate the influence weights of each parameter.The main conclusions are as follows: (1) Permeability distribution is the core factor controlling the fracture propagation direction, with HPL dominating the extension path while MPL and LPL show limited efficiency. (2) An increase in the number of permeability layers inhibits the overall expansion of cracks, and the shape of the cracks gradually changes to rectangular. (3) Higher injection rates significantly expand fracture area, whereas fracturing fluid viscosity ≥50 mPa·s stabilizes fracture morphology. (4) The elastic coefficient method identifies injection rate, permeability heterogeneous, and fracturing fluid viscosity as the key control parameters in order. …”

Influence of Water Injection Pressure on Methane Gas Displacement by Coal Seam Water Injection
Published 2022-01-01“…The test results show that with the same displacement time, the ratio of displaced methane increases with the increase in the water injection pressure. The displacement rate increases with the increase in the water injection pressure at the stage without water discharge, while the water displacement rate under different water injection pressures differed slightly; in the later displacement stage, a higher water injection pressure of the coal sample results in a faster attenuation of the displacement rate and water displacement rate due to the decrease in the methane content in the coal sample. …”
