Nanoscale Ferroelectric Characterization with Heterodyne Megasonic Piezoresponse Force Microscopy.

Adv Sci (Weinh) 2021 Apr 15;8(8):2003993. Epub 2021 Feb 15.

Department of Mechanical Engineering National University of Singapore Singapore 117576 Singapore.

Piezoresponse force microscopy (PFM), as a powerful nanoscale characterization technique, has been extensively utilized to elucidate diverse underlying physics of ferroelectricity. However, intensive studies of conventional PFM have revealed a growing number of concerns and limitations which are largely challenging its validity and applications. In this study, an advanced PFM technique is reported, namely heterodyne megasonic piezoresponse force microscopy (HM-PFM), which uses 10 to 10 Hz high-frequency excitation and heterodyne method to measure the piezoelectric strain at nanoscale.

Public finance management and data availability for nutrition financing in India.

BMJ Glob Health 2021 04;6(4)

Accountability Initiative, Centre for Policy Research, New Delhi, India.

For investments to translate into improved public service delivery, having a strong public finance management (PFM) system that lays out the rules, institutions and processes by which public funds are managed is critical. To enable a better understanding of the nutrition financial landscape, this paper seeks to determine whether the current PFM system in India allows for capturing required nutrition data. It does this by mapping the availability and comparability of data for a set of key nutrition-specific interventions through the budget cycle: from budget formulation, to execution, and finally, evaluation.

Fifteen years later: moving forward Heller's heritage on fiscal space for health.

Health Policy Plan 2021 Apr 15. Epub 2021 Apr 15.

Center for Global Development, 2055 L St NW, Washington, DC 20036, USA.

Economist Peter Heller, writing a seminal paper published in Health, Policy and Planning in 2006, identified five opportunities for expanding fiscal space for health: raising revenue, reprioritizing expenditure, borrowing, using seigniorage and mobilizing external grants. The development of the initial framework marked a significant conceptual advancement in health financing, by situating health reforms within a broader macro-fiscal context. Fifteen years later, fiscal space for health is not viewed simply as a question of finding additional revenues but also as a matter of improving public financial management (PFM) in the health sector, specifically for publicly funded health systems.

Characterization of Pelvic Floor Activity in Healthy Subjects and with Chronic Pelvic Pain: Diagnostic Potential of Surface Electromyography.

Sensors (Basel) 2021 Mar 23;21(6). Epub 2021 Mar 23.

Centro de Investigación e Innovación en Bioingeniería, Universitat Politècnica de València, 46022 Valencia, Spain.

Chronic pelvic pain (CPP) is a highly disabling disorder in women usually associated with hypertonic dysfunction of the pelvic floor musculature (PFM). The literature on the subject is not conclusive about the diagnostic potential of surface electromyography (sEMG), which could be due to poor signal characterization. In this study, we characterized the PFM activity of three groups of 24 subjects each: CPP patients with deep dyspareunia associated with a myofascial syndrome (CPP group), healthy women over 35 and/or parous (>35/P group, i.

Band Excitation Piezoresponse Force Microscopy Adapted for Weak Ferroelectrics: On-the-Fly Tuning of the Central Band Frequency.

Microsc Microanal 2021 Apr;27(2):326-336

Moscow Institute of Physics and Technology, 9 Institutskiy Lane, Dolgoprudny, Moscow Region141700, Russia.

New interest in microscopic studies of ferroelectric materials with low piezoelectric coefficient, $d_{33}^\ast$, has emerged after the discovery of ferroelectric properties in HfO2 thin films, which are the main candidate for the next generation of nonvolatile ferroelectric memory. The study of the microscopic structure of ferroelectric HfO2 capacitors is crucial to get insights into the device behavior and performance. However, a small $d_{33}^\ast$ of ferroelectric HfO2 films leads to a low piezoresponse, especially in band excitation piezoresponse force microscopy (BE-PFM). Read More

How to balance the treatment of stress urinary incontinence among female athletes?

Arch Med Sci 2021 21;17(2):314-322. Epub 2020 Oct 21.

Department of Mother's and Child's Health, Poznań, Poland.

Urinary incontinence in the general population occurs in 7% of non-pregnant women under 39 years old, 17% of those 40 to 59 years old, and 23-32% of those over 60 years old. In athletes the prevalence is higher, especially in high-impact training and gravity sports. Pelvic floor muscles (PFM) have two important roles; they serve as the support for abdominal organs and are crucial for closure of the urethra, vagina and rectum. Read More

Neurourol Urodyn 2021 Mar 19. Epub 2021 Mar 19.

Department of Rehabilitation, Faculté de Médecine, Université Laval, Québec, Québec, Canada.

Aims: To investigate the intra- and inter-rater reliability of two-dimensional (2D) transperineal ultrasound imaging (USI) measures of bladder wall thickness (BWT), urethral length (UL), and parameters related to levator plate length (LP) and transient changes in LP during pelvic floor muscle (PFM) contraction, and on Valsalva in women who received radiation therapy (RT) for treatment of pelvic cancer.
