Article Abstract
Based on existing studies that provide the pressure spectra in turbulent flows from the asymptotic pressure structure function in the inertial range, this paper extends the pressure spectrum to the dissipation range by proposing a pressure structure function model that incorporates both the inertial and dissipation ranges. Existing experiment results were used to validate the proposed pressure structure function model first, and then the obtained pressure spectrum was compared with the simulation and measurement data in the literature and the wind-induced noise measured outdoors. All comparisons demonstrate that the pressure spectrum obtained from the proposed pressure structure function model can be used to estimate the pressure spectra in both the inertial and dissipation ranges in turbulent flows with a sufficiently large Reynolds number.

Background: Hypertension is a major global risk factor for cardiovascular disease and mortality. In Greece, prevalence is about 40%, with many cases undiagnosed or poorly managed. While doctors remain central to diagnosis and treatment, community pharmacists, as accessible healthcare professionals, can support early detection and ongoing management.

The effects of pressure on the crystal structure of scheelite-type perrhenates were studied using synchrotron powder X-ray diffraction and density-functional theory. At ambient conditions, the studied materials AgReO, KReO, and RbReO, exhibit a tetragonal scheelite-type crystal structure described by space group 4/. Under compression, a transition from scheelite-to-M'-fergusonite (space group 2/) was observed at 1.

Background: Older adults in rural China bear a significant proportion of their healthcare expenses through out-of-pocket payments, resulting in a considerable financial burden on their families.
Objective: This study aimed to explore the key factors influencing adult children's involvement in financing healthcare expenses for their elderly parents in rural China.
Methods: Data were collected by in-depth interviews using a semi-structured interview guide approved by all researchers.

Background And Aim: The () gene plays a pivotal role in regulating growth, metabolism, and fat deposition in cattle. Genetic polymorphisms in this gene can influence phenotypic traits and may serve as molecular markers for selection in breeding programs. However, comprehensive characterization of gene variants in local Indonesian breeds, such as Madura cattle, remains limited.

Background: Idiopathic normal pressure hydrocephalus (iNPH) predominantly manifests with gait disturbances, yet clinical assessments are vulnerable to confirmation bias, particularly post-shunt surgery. Blinded video evaluations are a method to enhance objectivity in gait assessment, but their reliability has never been systematically investigated. The aim was to evaluate the inter-rater reliability of blinded gait assessments in iNPH patients and to investigate how these assessments correlate with the Hellström iNPH scale and patient-reported health status following shunt surgery.
