Recently, the self-supervised pre-training paradigm has shown great potential in leveraging large-scale unlabeled data to improve downstream task performance. However, increasing scale of real-world scenarios requires prohibitive computational costs and faces challenge uncurated samples. To address these issues, we build a task-specific framework from selection perspective based on simple hypot...

Head-down tilt bed rest (HDBR) has been used as a spaceflight analog to simulate the effects of microgravity exposure on human physiology, sensorimotor function, and cognition on Earth. Previous studies have reported that concurrent performance of motor and cognitive tasks can be impaired during space missions. Understanding the consequences of HDBR for neural control of dual tasking may possib...

OBJECTIVE To determine the haemodynamic effects of intensive care physiotherapy after liver transplantation. PATIENTS AND METHODS Thirteen patients were included in the study after liver transplantation. The following physiotherapy programme were applied to the patients in intensive care unit: Respiratory physiotherapy, active joint movements, sitting in bed (first task), sitting at the edge ...

In task switching studies, pre-cuing of the upcoming task improves performance, indicating preparatory activation of the upcoming task-set, and/or inhibition of the previous task-set. To further investigate cue-based task preparation, the authors presented both valid and invalid task cues in a task switching experiment involving three tasks. Consistent with previous findings, a validity effect ...

Background. Increasingly, women are training and competing in mixed martial arts (MMA). Women are, however, hugely underrepresented in the research literature. Objectives. The purpose of this brief report was to assess concussion knowledge, mental health and attention-related errors among female MMA competitors and factors that might affect data quality when doing a study during a competition....

In Internet of Things (IoT) sensory environment Wireless Sensor Networks (WSNs) are connected to the Internet through gateways and this gives birth to many real time sensor based applications. Applications from Internet querying for Spatio-temporal information within WSN may require query decomposition. Decomposition of queries may result in tasks having similar functional and Quality of Servic...

This research showed that appropriate input and suitable contexts for interaction among students can lead to successful  second language acquisition (SLA). This study based on Swain's (2005) notion of collaborative dialogue, aimed to study whether EFL learners participating in negotiation of meaning based tasks collaborate with each other and, if so, to investigate the role of this behavior in ...
