The lack of publicly available annotated databases is one of the major barriers to research advances on emotional information processing. In this contribution we present a recently collected database of spontaneous emotional speech in German which is being made available to the research community. The database consists of 12 hours of audio-visual recordings(More)
We present novel methods for estimating spontaneously expressed emotions in speech. Three continuous-valued emotion primitives are used to describe emotions, namely valence, activation, and dominance. For the estimation of these primitives, support vector machines (SVMs) are used in their application for regression (support vector regression, SVR). Feature(More)
The higher plant Arabidopsis thaliana (Arabidopsis) is an important model for identifying plant genes and determining their function. To assist biological investigations and to define chromosome structure, a coordinated effort to sequence the Arabidopsis genome was initiated in late 1996. Here we report one of the first milestones of this project, the(More)
Emotion primitive descriptions are an important alternative to classical emotion categories for describing a human’s affective expressions. We build a multi-dimensional emotion space composed of the emotion primitives of valence, activation, and dominance. In this study, an image-based, text-free evaluation system is presented that provides intuitive(More)
In this paper, we present novel methods for estimating spontaneously expressed emotions using audio-visual information. Emotions are described with three continuous-valued emotion primitives, namely valence, activation, and dominance in a 3D emotion space. We used prosodic and spectral features to represent the audio characteristics of the emotional speech.(More)
Reactive oxygen species (ROS) are involved in the regulation of many physiological processes. However, overproduction of ROS under various cellular stresses results in cell death and organ injury and thus contributes to a broad spectrum of diseases and pathological conditions. The existence of different cellular sources for ROS and the distinct properties(More)
The multifunctional Ca(2+)/calmodulin-dependent protein kinase II (CaMKII) targets a number of Ca(2+) homeostatic proteins and regulates gene transcription. Many of the substrates phosphorylated by CaMKII are also substrates for protein kinase A (PKA), the best known downstream effector of beta-adrenergic receptor (beta-AR) signaling. While PKA and CaMKII(More)
Rigid head motion is a gesture that conveys important nonverbal information in human communication, and hence it needs to be appropriately modeled and included in realistic facial animations to effectively mimic human behaviors. In this paper, head motion sequences in expressive facial animations are analyzed in terms of their naturalness and emotional(More)
OBJECTIVES It has been proved in human subjects and animals that atelectasis is a major cause of intrapulmonary shunting and hypoxemia after cardiopulmonary bypass. Animal studies suggest that shunting can be prevented entirely by a total vital capacity maneuver performed before termination of bypass. This study aimed to test this theory in human subjects(More)
