Families of these probands (n = 88) were invited to participate in the study. The proband and his/her siblings received a battery of reading-related tasks and performance on these tasks(More)
Crowdsourced clustering approaches present a promising way to harness deep semantic knowledge for clustering complex information. However, existing approaches have difficulties supporting the global context needed for workers to generate meaningful categories, and are costly because all items require human judgments. We introduce Alloy, a hybrid approach(More)
Mixed language data is one of the difficult yet less explored domains of natural language processing. Most research in fields like machine translation or sentiment analysis assume monolingual input. However, people who are capable of using more than one language often communicate using multiple languages at the same time. Sociolinguists believe this "(More)
OBJECTIVE Fluoxetine, a selective serotonin reuptake inhibitor antidepressant agent, has been implicated in learning and memory. Here, we report four cases from the same family of fluoxetine-related memory-impairment. RESULTS Memory-impairment resulted after fluoxetine treatment and disappeared after changing to another selective serotonin reuptake(More)
Patients researching medical diagnoses, scientist exploring new fields of literature, and students learning about new domains are all faced with the challenge of capturing information they find for later use. However, saving information is challenging on mobile devices, where the small screen and font sizes combined with the inaccuracy of finger based touch(More)
This article reviews the varied process of transitioning and the psychosocial and quality-of-life benefits and outcomes of gender-affirmation therapeutic interventions, examines the barriers that transgender (TG) persons face in accessing health care, and describes the authors' experiences in improving access to medical services by launching a TG health(More)
A graph with a vertex set V is said to have a prime labeling if its vertices can be labeled with distinct integers 1; 2; ; jV j such that for every edge fx; yg, the labels assigned to x and y are relatively prime. A tree is prime if it has at least one prime labeling. Around 1980, Entringer conjectured that every tree is prime. After three decades, this(More)
