Boosting Sensitivity of Piezoelectric Sensors by Electrohydrodynamic Pulling Promoted In Situ Foaming.

Polymer-based piezoelectric sensors are gaining widespread attraction for wearable sensing applications due to their light weight, flexibility, and self-powered performance. Wherein high response sensitivity and good linearity are essential for piezoelectric sensors. However, conventional piezoelectric sensors are limited in their ability to exploit space fully to generate adequate strain, leading to a relatively low piezoelectric output and insufficient sensitivity under a broad stress linearity range. Herein, an electrohydrodynamic (EHD) pulling-promoted in situ foaming technology is propose

Exploration of Automated Measurement for Ossicular Chains Based on 3-Dimensional Geometric Information.

Abnormalities in the ossicular chain, a key middle-ear component that is crucial for sound transmission, can lead to conductive hearing loss; reconstruction offers an effective treatment. Accurate preoperative ossicular-chain measurements are essential for creating prostheses; however, current methods rely on cadaver studies or manual measurements from 2-dimensional images, which are time-intensive and laborious and depend heavily on radiologist expertise. To improve efficiency, we aimed to develop a systematic approach for automated ossicular-chain segmentation and measurement using ultra-hig

Enhancing Brain-Computer Interface Performance by Incorporating Brain-to-Brain Coupling.

Human cooperation relies on key features of social interaction in order to reach desirable outcomes. Similarly, human-robot interaction may benefit from integration with human-human interaction factors. In this paper, we aim to investigate brain-to-brain coupling during motor imagery (MI)-based brain-computer interface (BCI) training using eye-contact and hand-touch interaction. Twelve pairs of friends (experimental group) and 10 pairs of strangers (control group) were recruited for MI-based BCI tests concurrent with electroencephalography (EEG) hyperscanning. Event-related desynchronization (

Interlimb and Intralimb Synergy Modeling for Lower Limb Assistive Devices: Modeling Methods and Feature Selection.

CONTEXT: For clinicians managing weight loss in patients with HIV, it would be useful to understand how changes in lean body mass (LBM) effect physical functioning, and whether LBM is more strongly related to physical functioning than total body weight (TBW). OBJECTIVE: To determine the relationship of changes in LBM and changes in total body weight (TBW) to changes in self-reported physical functioning in men and women with HIV infection. METHODS: Study design was longitudinal analysis of 1474 patient-intervals (each interval was approximately 6 months long) in 486 persons. Patients were pa

Coevolution of Myoelectric Hand Control under the Tactile Interaction among Fingers and Objects.

The usability of a prosthetic hand differs significantly from that of a real hand. Moreover, the complexity of manipulation increases as the number of degrees of freedom to be controlled increases, making manipulation with biological signals extremely difficult. To overcome this problem, users need to select a grasping posture that is adaptive to the object and a stable grasping method that prevents the object from falling. In previous studies, these have been left to the operating skills of the user, which is extremely difficult to achieve. In this study, we demonstrate how stable and adaptiv

Robotic Intracellular Electrochemical Sensing for Adherent Cells.

Nanopipette-based observation of intracellular biochemical processes is an important approach to revealing the intrinsic characteristics and heterogeneity of cells for better investigation of disease progression or early disease diagnosis. However, the manual operation needs a skilled operator and faces problems such as low throughput and poor reproducibility. This paper proposes an automated nanopipette-based microoperation system for cell detection, three-dimensional nonovershoot positioning of the nanopipette tip in proximity to the cell of interest, cell approaching and proximity detection

Surgical Robot for Intraluminal Access: An Ex Vivo Feasibility Study.

Early-stage gastrointestinal cancer is often treated by endoscopic submucosal dissection (ESD) using a flexible endoscope. Compared with conventional percutaneous surgery, ESD is much less invasive and provides a high quality of life for the patient because it does not require a skin incision, and the organ is preserved. However, the operator must be highly skilled because ESD requires using a flexible endoscope with energy devices, which have limited degrees of freedom. To facilitate easier manipulation of these flexible devices, we developed a surgical robot comprising a flexible endoscope a

A Forgiveness Intervention for Women With Fibromyalgia Who Were Abused in Childhood: A Pilot Study.

This pilot study compared the efficacy of a forgiveness intervention with a fibromyalgia (FM) health intervention on women with FM who have experienced emotional, physical, or sexual abuse, and emotional or physical neglect, in childhood by one of their parents. Eleven women with FM between the ages of 21 and 68 were randomized to the forgiveness intervention (n = 5) or the FM health intervention (n = 6), and completed the once-weekly individualized program for 24 weeks. The participants completed measures assessing forgiveness, overall FM health, depression, anger, anxiety, self-esteem, and c

OBJECTIVES: The United Kingdom has committed to World Health Organization goals to eliminate hepatitis C virus (HCV) by 2030. Peer-led services (PLS) may enhance health care engagement and treatment outcomes. We compared progression through the HCV care cascade between those tested in a community using PLS (PLS group) with a population tested in drug services (non-PLS group) in England. METHODS: We extracted data on individuals with HCV-RNA test results from a laboratory surveillance system (2019-2023) and linked them to a national HCV treatment database. We identified individuals tested by t

Association Between Soda or Sports Drink Consumption and a Past-Year Dentist Visit: National Survey Among American Indian or Alaska Native High School Students, 2023.

OBJECTIVES: Sugar-sweetened beverages (SSBs) are the leading contributor of added sugars in the diets of children, adolescents, and young adults aged 2 to 19 years and are associated with chronic diseases, including oral health conditions such as dental caries. We assessed the possible association between the consumption of soda or sports drinks (SSDs), 2 types of SSBs, and past-year dentist visits among American Indian or Alaska Native (AI/AN) high school students because this population has unique challenges related to oral health (eg, barriers to access to care) that might increase SSD cons

A cross-species test of cognitive flexibility: Assessing the influence of phrasing cue modality on serial pattern performance in rats (Rattus norvegicus) and humans (Homo sapiens).

The serial multiple choice task is a cross-species model of serial pattern learning that recruits multiple cognitive mechanisms concurrently. The task requires subjects to learn a complex sequence of responses that follow a specific pattern, which is further organized by the placement of distinct cues throughout the sequence. These cues, termed phrasing cues, denote locations in the pattern where response strategy shifts. Although research suggests that phrasing cues facilitate pattern learning, there is a lack of information on how subjects encode these phrasing cues during the pattern learni
