Color superposition: a new modality for contrast echocardiography.
1987
To improve the estimation of endocardial borders in echocardiography, a technique has been developed to combine images from contrasted and noncontrasted echocardiograms of the same heart-phase using a color superposition mode. This method allows both experienced as well as less experienced examiners to define the endocardial borders more reproducibly and objectively. This is achieved by displaying tissue structures as gray level images while the ventricular cavity is marked selectively by the color display of the contrast material zone. Results of volume estimations of the left ventricle by different examiners using several imaging modes including color superposition display are presented.
Attempt to Construct a Scale for the Measurement of the Effect of Suggestion on Perception1
1975
A scale based on experimental methods has been prepared for measuring the effects of indirect suggestion upon perception. Three categories are included: (1) distorting the interpretation of presented stimuli, (2) inducing sense-impressions in the absence of adequate stimuli, and (3) producing insensitivity to stimuli that are objectively present. Test situations were designed for tactual, auditory, and visual perception. The scale was tested on a sample of 112 students from the 11th and 12th grades of a large city high school (58 girls and 54 boys). Most of the item intercorrelations were positive and many significantly so. Eliminating the 9 lowest items of 21 left 12 for a reduced matrix,…
Application of finger span cross modality matching method (FSCM) by naive assessors for olfactometric discrimination of Gewürztraminer wines
2002
Abstract A gas-chromatography-olfactometric detection (GCO) using a direct estimation of odor intensities with the finger span (FSCM) was used to establish aroma profiles of three wines of gewurztraminer from different ‘terroirs’ of the Alsace region. The GCO-FSCM analyses of their hydroalcoholic wine extracts were performed using a group of untrained assessors. Forty-four olfactory signals were perceived by at least four assessors out of six and their intensities were scored in triplicate in each of the three wine extracts, amongst which ten of them were found discriminant between wines. The reliability of each assessor was studied on the basis of the finger span estimation repeatability, …
Exploiting multimodality for intelligent mobile access to pervasive services in cultural heritage sites
2010
In this chapter the role of multimodality in intelligent, mobile guides for cultural heritage environments is discussed. Multimodal access to information contents enables the creation of systems with a higher degree of accessibility and usability. A multimodal interaction may involve several human interaction modes, such as sight, touch and voice to navigate contents, or gestures to activate controls. We first start our discussion by presenting a timeline of cultural heritage system evolution, spanning from 2001 to 2008, which highlights design issues such as intelligence and context-awareness in providing information. Then, multimodal access to contents is discussed, along with problems an…
A study on texture-taste-aroma interactions: physico-chemical and cognitive mechanisms
2009
International audience; Texture–taste, texture–aroma and aroma–taste interactions were examined in custard desserts varying in viscosity (at identical composition), sucrose level and aroma nature. All reciprocal interactions were investigated, with each binary interaction addressed through an independent sensory study. Rheological, in vivo aroma release and sucrose release measurements were run in parallel to control for a possible physico-chemical origin of these interactions. Observed interactions were found to be dependent upon the nature of the sensory modalities involved; physico-chemical mechanisms could only in some instances entirely explain these interactions. Taste and aroma did n…
Metaphorical GIFs and humour online: the case of “when” posts on Tumblr
2021
International audience; “When” posts have now become a staple of microblogging platforms such as Twitter, Tumblr or Facebook. They consist of two things: a verbal caption opening with “When” followed by an assertive clause describing a situation of life on the one hand, and a static or moving image presenting a visual elaboration of the situation described in the caption on the other hand. “When” posts rely on the striking relationship between what the caption describes and what the image shows. In the case of the posts selected for the present study, this relationship is metaphorical: the caption and the image, which are juxtaposed without mediation, act respectively as a verbal tenor and …
Epistemic Modality Variation in Community Law Journals
2012
Over the last decades the attention of scholars working in the filed of academic discourse has been directed towards language variation, and academic writing is not any more considered as a consistent and homogeneous form of discourse. The importance traditionally given to the consensual and static aspects of disciplinary communication has been coupled with the emphasis increasingly placed to the analysis of interactions/practices/activities that sustain discourse communities. According to the sociolinguist approach, genres become ‘dynamically rhetorical structures’ that can be manoeuvred according to the discipline’s norms, values and ideology, both historically and incrementally changing …
Epistemic Modality Markers in European and American Law Journals
2013
Over the last decades the attention of scholars working in the filed of social sciences has been directed towards language variation, and discourse analysis has increasingly evolved as a valuable way of understanding the use of language in a variety of academic, institutional and professional settings (Clyne 1994; Flowerdew & Gotti 2006; Bhatia et al. 2008). According to the sociolinguist approach, genres become ‘dynamically rhetorical structures’ that can be manoeuvred according to the discipline’s norms, values and ideology, both historically and incrementally changing as disciplinary knowledge and genres required and created by discourse communities’ change (Bhatia 2004; Hyland 2004,…
A Deep Learning Model for Automatic Sleep Scoring using Multimodality Time Series
2021
Sleep scoring is a fundamental but time-consuming process in any sleep laboratory. Automatic sleep scoring is crucial and urgent to help address the increasing unmet need for sleep research. Therefore, this paper aims to develop an end-to-end deep learning architecture using raw polysomnographic recordings to automate sleep scoring. The proposed model adopts two-dimensional convolutional neural networks (2D-CNN) to automatically learn features from multi-modality signals, together with a "squeeze and excitation" block for recalibrating channel-wise feature responses. The learnt representations are finally fed to a softmax classifier to generate predictions for each sleep stage. The model pe…
Modalność epistemiczna w ustnych wypowiedziach maturzystów
2016
In this article the author analyses components of the epistemic modality, by means of which a student assesses the accuracy of views presented during the oral matriculation examination in the Polish language. Considering the specificity of spoken utterances during the oral matriculation examination, the epistemic modality can be defined as all kinds of information on an intellectual attitude of the speaker who, on the basis of his/her own knowledge and thinking processes which are taking place in his/her mind al a given moment, makes a “gradable” assessment of a view’s reliability. The analysed texts differ depending on the level of certainty of their authors as far as the communicated cont…
