Behavior of echocardiographic parameters of right ventricular function after tricuspid surgery.

Evaluation of right ventricular (RV) function after tricuspid valve surgery is complex. The objective was to identify the most appropriate RV function parameters for this purpose. This prospective study included 70 patients undergoing cardiac and tricuspid valve (TV) surgery.

Can the 'Learn in peace, educate without violence' intervention in Cote d'Ivoire reduce teacher violence? Development of a theory of change and formative evaluation results.

Objectives: To gather evidence on whether a brief intervention (Apprendre en paix et éduquer sans violence, developed by the Ivorian Ministry of Education and Graines de Paix) to promote peace in primary schools by reducing teacher violence perpetration and improving pedagogical techniques was acceptable to teachers and affected change in intermediate outcomes.

Design: Mixed-methods formative research.

Setting: Primary schools in Tonkpi region, Cote d'Ivoire.

Emotional Networked maps from EEG signals.

The EEG has showed that contains relevant information about recognition of emotional states. It is important to analyze the EEG signals to understand the emotional states not only from a time series approach but also determining the importance of the generating process of these signals, the location of electrodes and the relationship between the EEG signals. From the EEG signals of each emotional state, a functional connectivity measurement was used to construct adjacency matrices: lagged phase synchronization (LPS), averaging adjacency matrices we built a prototype network for each emotion.

Measuring violence perpetration: Stability of teachers' self-reports before and after an anti-violence training in Cote d'Ivoire.

Background: Epidemiological studies of interpersonal violence commonly use self-reported violence perpetration as an outcome measure, but few studies have investigated the stability of and influences on self-reports.

Objective: To assess changes in teachers' self-reported use of physical violence against students before and after a one-day violence prevention training, and factors associated with changed reports in Cote d'Ivoire.

Methods: Before and after the training, 157 teachers completed surveys containing 32 questions adapted from the ICAST-CI.

Emotion Recognition from EEG and Facial Expressions: a Multimodal Approach.

The understanding of a psychological phenomena such as emotion is of paramount importance for psychologists, since it allows to recognize a pathology and to prescribe a due treatment for a patient. While approaching this problem, mathematicians and computational science engineers have proposed different unimodal techniques for emotion recognition from voice, electroencephalography, facial expression, and physiological data. It is also well known that identifying emotions is a multimodal process.

Organocatalytic Enantioselective Synthesis of α-Hydroxyketones through a Friedel-Crafts Reaction of Naphthols and Activated Phenols with Aryl- and Alkylglyoxal Hydrates.

An efficient organocatalytic asymmetric synthesis of α-hydroxyketones has been developed. Quinine-derived thiourea catalyzed the enantioselective Friedel-Crafts alkylation of naphthols and activated phenols with aryl- and alkylglyoxal hydrates, providing the corresponding chiral α-hydroxyketones with high yields (up to 97%) and excellent enantioselectivities (up to 99% ee).
