AI Article Synopsis
- The study demonstrates how to create and maintain liquid columns with high aspect ratios, exceeding those typically associated with the Rayleigh-Plateau instability.
- An acoustic beam applied at the top of the column provides passive feedback that stabilizes the column by balancing sound and surface tension forces.
- An analytical model was developed to explain this balance, and it shows strong agreement with experimental results.
Article Abstract
We report on the formation and sustainment of liquid columns with aspect ratios much larger than the value at the onset of the Rayleigh-Plateau instability. This is achieved by using the passive feedback of the radiation pressure applied on the column surface by an acoustic beam injected at the upper end of the column and guided along it. We develop an analytical model that describes the coupling between the acoustic wave guiding and the balance between acoustic and capillary surface forces exerted on the column surface and find a satisfactory agreement with the experiment.

Background: Cutaneous leishmaniasis is one of the neglected tropical diseases which is hard to treat. Carbon dioxide-based cryotherapy is a novel therapeutic option for cutaneous leishmaniasis in both developed and developing nations. This study aims to summarize the pooled evidence on the effectiveness of carbon dioxide-based cryotherapy for the treatment of cutaneous leishmaniasis.

To decrease the high rates of mental health-related maternal morbidity and mortality among rural-dwelling women, it is critical to identify those experiencing postpartum depression (PPD) and provide necessary follow-up care. To effectively screen for PPD, clinicians must utilize instruments which account for context-specific factors and maintain validity across diverse populations. The Edinburgh Postnatal Depression Scale (EPDS) is the most commonly used depression screening tool in perinatal settings, but has not been validated for use within rural American settings.

Through non-dimensional analysis of the nonlinear sound absorption characteristics of rigid-porous layers, the results indicate that the nonlinear sound absorption trend of a porous layer (PL) at high sound pressure levels (SPLs) mainly depends on the state of flow resistance matching. When a PL is in an under-matched state, the sound absorption coefficient (SAC) will initially rise to a maximum and then gradually decline as SPL increases. Comparatively, when it is in an over-matched state, the SAC will decrease monotonically.

As a tool for operationalizing basic psychological needs theory (an aspect of self-determination theory), the Basic Psychological Needs Satisfaction and Frustration Scale (BPNSFS) has become the primary self-report measure. Here, with a sample of 807 Canadian military members, we confirm the BPNSFS six content factor structure and, in supporting that structure, demonstrate the differential association of satisfaction and frustration scales with psychological functioning variables that are external to the factor analysis. Although the specific content interpretation of the BPNSFS can be debated, we support the continued use of the BPNSFS as a psychometrically sound instrument.

Single-sided deafness (SSD), where there is severe to profound hearing loss in one ear and normal hearing in the other, is a prevalent auditory condition that significantly impacts the quality of life for those affected. The ability to accurately localize sound sources is crucial for various everyday activities, including speech communication and environmental awareness. In recent years, bone conduction intervention has emerged as a promising solution for patients with SSD, offering a non-invasive alternative to traditional air conduction hearing aids.
