Evaluation of a vibrotactile feedback device for spatial guidance

, 2011
In the present study, a vibrotactile feedback device for spatial guidance was evaluated in a tracking task paradigm. Participants (N = 18) had to translate and rotate virtual objects according to the vibrotactile vs.

Evaluation of the Visual Environment of Community Third Places Based on Emotional Perceptions

Buildings
A well-designed visual environment in community third places has significant positive effects on residents’ emotional well-being. Only a few studies have examined these effects; therefore, this study comprehensively explores the effect of the visual ...

The feeling of agency: Empirical indicators for a pre-reflective level of action awareness

Frontiers in Psychology, 2011
The sense of agency has been defined as the sense that I am the author of my own actions. This sense, however, is usually not reflected upon but instead pre-reflectively experienced.

A balance equation determines a switch in neuronal excitability. [PDF]

PLoS Computational Biology, 2013
We use the qualitative insight of a planar neuronal phase portrait to detect an excitability switch in arbitrary conductance-based models from a simple mathematical condition. The condition expresses a balance between ion channels that provide a negative

Physiological Positive Feedback Mechanisms

American Journal of Biomedical Sciences, 2011
In positive feedback mechanisms, the response to a stimulus does not stop or reverse it but instead keeps the sequence of events going up. At first glance, this would appear to be a counter to the principle of homeostasis, since a positive feedback loop has no obvious means of stopping.

On the global attractor of delay differential equations with unimodal feedback

, 2009
We give bounds for the global attractor of the delay differential equation x(over dot) (t) = -mu x(t) + f(x(t - tau)), where f is unimodal and has negative Schwarzian derivative.

Affective feedback: an investigation into the role of emotions in the information seeking process [PDF]

, 2008
User feedback is considered to be a critical element in the information seeking process, especially in relation to relevance assessment. Current feedback techniques determine content relevance with respect to the cognitive and situational levels of ...

Dietary Protein Intake and Peritoneal Protein Losses in Peritoneal Dialysis Patients

Therapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Introduction Peritoneal dialysis (PD) patients lose protein in their waste dialysate, potentially increasing their risk for malnutrition. We wished to determine whether there was any association between losses and dietary protein intake (DPI). Methods DPI was assessed from 24‐h dietary recall using Nutrics software.

Control strategy for anaesthetic drug dosage with interaction among human physiological organs using optimal fractional order PID controller

, 2014
In this paper, an efficient control strategy for physiological interaction based anaesthetic drug infusion model is explored using the fractional order (FO) proportional integral derivative (PID) controllers.

Understanding Implicit User Feedback from Multisensorial and Physiological Data [PDF]

, 2020
Ensuring the quality of user experience is very important for increasing the acceptance likelihood of software applications, which can be affected by several contextual factors that continuously change over time (e.g., emotional state of end-user).
