Subsurface damage identification and localization in PZT ceramics using point contact excitation and detection: An image processing framework.

Piezoelectric sensors hold immense potential in structural health monitoring (SHM) applications. However, their performance can be deteriorated by defects and extreme weathering. Therefore, diagnosing the sensor before implementation is very crucial.

Association Between Pain and Fall Worry Among Community-Dwelling Older People With Cognitive Impairment in the United States.

Background And Objectives: Previous studies have found that pain is associated with fall worry among community-dwelling older people. However, both pain and fall worry are poorly understood and underaddressed among community-dwelling older people with cognitive impairment (CI). It is essential to examine the association between pain and fall worry, and how sociodemographic and health characteristics may shape fall worry among this subgroup.

Breathy Voice as a Compensatory Strategy for Essential Vocal Tremor: A Single Case Experiment Across Participants.

Objective: Essential vocal tremor (EVT) manifests as nearly rhythmic modulations of fundamental frequency (f) and intensity and causes a shaky voice. Although research on behavioral therapy for EVT is limited, previous studies have shown that a breathy voice reduces the perception of simulated EVT and might be an effective compensatory strategy. The current study aimed to measure the acoustical and perceptual effects of a breathy voice strategy in speakers with EVT.

An Ethical Framework for Research Using Genetic Ancestry.

A wide range of research uses patterns of genetic variation to infer genetic similarity between individuals, typically referred to as genetic ancestry. This research includes inference of human demographic history, understanding the genetic architecture of traits, and predicting disease risk. Researchers are not just structuring an intellectual inquiry when using genetic ancestry, they are also creating analytical frameworks with broader societal ramifications.

Ancestry: How researchers use it and what they mean by it.

Ancestry is often viewed as a more objective and less objectionable population descriptor than race or ethnicity. Perhaps reflecting this, usage of the term "ancestry" is rapidly growing in genetics research, with ancestry groups referenced in many situations. The appropriate usage of population descriptors in genetics research is an ongoing source of debate.

Getting genetic ancestry right for science and society.

We must embrace a multidimensional, continuous view of ancestry and move away from continental ancestry categories.

Effect of Blood Group on Ultrahigh Frequency Auditory Sensitivity.

 Individuals with blood group O are reported to have reduced otoacoustic emissions (OAEs) compared with individuals with different blood groups.  The present study attempted to determine if the blood group has any effect on high-frequency auditory sensitivity using ultrahigh-frequency audiometry and ultrahigh-frequency distortion product otoacoustic emissions (DPOAEs).  High-frequency thresholds and high-frequency DPOAEs were measured in 60 individuals with normal hearing and different blood groups.
