BACKGROUND: Myocyte apoptosis is seen in ischemic heart disease, but whether it can occur after reversible ischemia or independent of necrosis and replacement fibrosis is unknown. METHODS AND RESULTS: Pigs were instrumented with a stenosis of the left anterior descending coronary artery to chronically reduce coronary flow reserve over a period of 3 months. At this time, there was viable dysfunctional myocardium having the physiological features of hibernating myocardium. Resting subendocardial p

The electrical characteristics were evaluated for the metal-oxide-semiconductor (MOS) devices with Ti and Pt gates on the atomic-layer-deposited (ALD) HfO2. The equivalent oxide thickness (EOT) of the Ti gate is shown to be nearly the same as that of the Pt gate, which means that a negligible chemical reaction occurs between the gate and dielectric. The values of the effective metal work function (Φm,eff), extracted from the conventional relations of flatband voltage versus EOT, were ∼4.2eV for

Previous research has shown that communication technologies may make it challenging for working professionals to manage the boundaries between their work life and home life. For college students, however, there is a less clear definition of what constitutes work and what constitutes home life. As a result, students may use different boundary management strategies than working professionals. To explore this issue, we interviewed 29 undergraduates about how they managed boundaries between differen

Many people's social media feeds include posts in languages they do not understand. While previous research has examined bilingual social media users' language choices, little research has focused on how people make sense of foreign language posts. In the present study, we interviewed 23 undergraduate social media users about how they consume and make sense of posts in other languages. Interviewees reported that they often did not pay attention to or engage with foreign language posts, due to a

Selfies are everywhere on social media. Research has focused only on who is posting selfies and has not addressed the audience members viewing selfies. This study aims to fill this gap by analyzing the judgments people make of selfies posted on Facebook. Using an online experiment, we test how including a selfie on a Facebook status update changes people's appraisals of narcissism, message appropriateness, and social attraction. We also consider how the valence and intimacy of the status update

Many families often live geographically apart from each other due to work, education, or marriage. Therefore, long-distance families frequently use computer-mediated communication (CMC) tools to stay connected. While CMC tools have significantly improved family communication, they cannot fully mediate social presence. To examine the potential of telepresence robots for improving long-distance family communication, we conducted a two-week qualitative in situ study involving eight families. We ana

Although many social media sites now provide machine translation (MT) for foreign language posts, translation of a post may not suffice to support understanding of, and engagement with, that post. We present SenseTrans, a tool that provides emotional and contextual annotations generated by natural language analysis in addition to machine translation. We evaluated SenseTrans in a laboratory experiment in which native English speakers browsed five Facebook profiles in foreign languages. One group

Traumatic brain injury (TBI) can result in chronic sensorimotor, cognitive, psychosocial, and communication challenges that can limit social participation. Social media can be a useful outlet for social participation for individuals with TBI, but there are barriers to access. While research has drawn attention to the nature of access barriers, few studies have investigated technological solutions to address these barriers, particularly considering the perspectives of individuals with TBI. To add

School counsellors in South Korea face significant emotional exhaustion due to their challenging occupational environment. Previous studies have shown that cognitive reappraisal (CR) reduces emotional exhaustion, whereas expressive suppression (ES) increases it. However, these findings predominantly rely on trait questionnaires within cross-sectional approaches, overlooking the dynamic nature of emotion regulation (ER) strategy selection. Individuals may choose strategies that deviate from their

Abstract This study investigated the impact of surface acting on exhaustion in Korean school counselors. Using the daily diary method with 223 school counselors, the study examined how maintaining a positive outward image through surface acting is related to job exhaustion. The results indicated that surface acting at both Level 1 and Level 2 positively affects exhaustion. Additionally, a supportive administrative climate negatively predicted exhaustion. Interestingly, the relationship between s

Communication tools such as email facilitate communication and collaboration between speakers of different languages, who use two primary strategies-English as a common language and machine translation (MT) tools-to help them overcome language barriers. However, each of these communication strategies creates its own challenges for cross-lingual communication. In this paper, we compare how people's interpretations of an email sender's social intention, and their evaluation of the email and the se

The widespread use of mobile devices has transformed casual places into meeting places. However, in these places, it is uncommon to have shared information workspace such as a beam projector, making it inconvenient and inefficient to exchange information and to get a direct feedback. To address this challenge, we present Ubi-jector, a mobile system that provides a shared information space that is equally distributed to each participant's mobile device and allows group members to share documents

We explore how language affects people’s attention to and engagement with social media posts in an eye-tracking experiment in which participants viewed a mock newsfeed containing English and foreign language posts, half with and half without images. Participants spent less time looking at foreign language posts than English posts, and more time looking at posts with images than those without images. Participants reported being more likely to like or comment on posts in English and posts with ima

The goal of this paper is to investigate how computational tools to annotate communication can support multilingual sense-making on social media. We conducted a field study of SenseTrans, a browser extension that uses sentiment analysis and named entity extraction techniques to annotate Facebook posts with emotional and contextual information. Interviews with 18 participants who used SenseTrans in their Facebook newsfeed for two weeks suggest that the annotations often supported sensemaking by p
