Electrochemical impedance spectroscopy (EIS) is a widely applied non-destructive method of characterisation of Li-ion batteries. Despite its ease of application, there are inherent challenges in ensuring the quality and reproducibility of the measurement, as well as reliable interpretation and validation of impedance data. Here, we present a focus review summarising best metrological practice in the application of EIS to commercial Li-ion cells. State-of-the-art methods of EIS interpretation and

This study examined the potential of universal design in the field of apparel. The particular purpose of the study was to explore the use of the concept and principles of universal design as guidance for developing innovative design solutions that accommodate ‘inclusivity’ while maintaining ‘individuality’ regarding the wearer's aesthetic tastes and functional needs. To verify the applicability of universal design in apparel products, two case studies of design practice were conducted, and the p

This experimental study aimed to investigate the effect of having a virtual avatar experience on health outcomes in the context of body image and weight regulation. Ninety-three U.S. non-clinical participants (51 men and 42 women) were recruited, who were 18 years and older and had no history of chronic health problems or mental illnesses. Each experiment consisted of the three data collection phases, including the pre-experiment survey, an experience session of a virtual self-avatar, and the po

<i>Purpose</i>. The objective of this study was to compare the effects of personal protective equipment (PPE) on firefighters' perceptions of mobility and their experienced occupational injury risks between China and the USA. <i>Materials and methods.</i> An online survey was conducted and a total of 328 firefighters, including 203 Chinese firefighters and 125 US firefighters, participated in the survey. <i>Results.</i> Both Chinese and US firefighters ranked mobility restriction as the most dis

In order to gauge the emerging needs for the plus-size footwear market, this study tested the following four hypotheses: 1) as BMI increases, foot morphology changes; 2) increased BMI influences consumers' footwear selection criteria; 3) increased BMI negatively affects consumers' footwear fit; and 4) increased BMI negatively affects consumers' satisfaction with the current footwear market. One hundred and twenty-one female college students were recruited from a large 4-year U.S. university, and

Abstract We explored how viewing one’s anthropometric virtual avatar would affect the viewer’s self-body perception through the comparative evaluation of self-concepts—self-esteem and self-compassion, within the framework of allocentric lock theory. We recruited 18 female adults, aged 18–21, who identified themselves to have some level of body image concerns, and who had had no clinical treatment for their body image. Participants were randomly assigned either to the experimental or control grou

In histopathology, acquiring subcellular-level three-dimensional (3D) tissue structures efficiently and without damaging the tissues during serial sectioning and staining remains a formidable challenge. We address this by integrating holotomography with deep learning and creating 3D virtual hematoxylin and eosin (H&E) images from label-free thick cancer tissues. This method involves measuring the tissues' 3D refractive index (RI) distribution using holotomography, followed by processing with a d

Drawing on 68 interviews with South Korean students at elite U.S. colleges, this article examines the intersectional power of gender and class in elite transnational parenting—a family strategy for class reproduction. Well-educated, stay-at-home mothers intensively managed their children’s school activities, often relying on gender-segregated networks, mostly during early school years. By contrast, cosmopolitan professional fathers heavily engaged in guiding their children’s education abroad and

The purpose of this study is to investigate whether the differences in visualisation patterns are related to a viewer's previous training in design appreciation, and whether aesthetic visualisation is trainable in a short term. Forty-three female subjects, consisting of 20 trained and 23 untrained viewers, participated. Twenty fashion images, posed by a male and a female model, were shown on an eye-tracker screen for 10 s each. This study revealed that the trained viewer tended to show longer ga

This study proposed an integrative three-stage process model (integrative process model for universal design [IPM-UD]) as guidance for universal design practices, particularly for apparel. The IPM-UD consolidated the universal design principles and the functional–expressive–aesthetic attributes. The model validity was evaluated with an empirical design case of hospital patient apparel. To identify specific user needs, survey data were collected from 173 patients and healthcare providers at 2 lar

Clear cell renal cell carcinoma (ccRCC) is a common histopathological subtype of renal cancer and is notorious for its poor prognosis. Its accurate diagnosis by histopathology, which relies on manual microscopic inspection of stained slides, is challenging. Here, we present a correlative approach to utilize stained images and refractive index (RI) tomography and demonstrate quantitative assessments of the structural heterogeneities of ccRCC slides obtained from human patients. Machine-learning-a

We identified fit and comfort issues in the hospital patient gown (HPG) that evoke the patients’ physical and psychological discomfort caused by wearing an ill-fitting garment. This research inquiry required a holistic perspective to comprehend the research phenomenon from the convoluted individual variance. To achieve the goal, we developed a mixed-methods strategy that consisted of the surveys, 3D body scanning, scenarios activities, and exit interviews, and conducted the study with 85 partici
