Mining code change patterns to aid software development

Fengcai, Wen ; Bavota, Gabriele (Dir.) ; Lanza, Michele (Codir.)

Thèse de doctorat : Università della Svizzera italiana, 2021 ; 2021INFO012.

Mining Software Repositories (MSR) has become a complete and mature research field, also due to the increasing number of open source projects publicly available. Repository hosting services such as GitHub provide unprecedented access to millions of events generated during development activities (e.g., code commits, pull requests), that can be mined and analyzed to extract new pieces of...

Striatal reactivity to reward under threat-of-shock and working memory load in adults at increased familial risk for major depression: A preliminary study

Gaillard, Claudie ; Guillod, Matthias ; Ernst, Monique ; Federspiel, Andrea ; Schoebi, Dominik ; Recabarren, Romina Evelyn ; Ouyang, Xinyi ; Mueller-Pfeiffer, Christoph ; Horschg, Antje ; Homan, Philipp ; Wiest, Roland ; Hasler, Gregor ; Martin-Soelch, Chantal

Introduction: Anhedonia, a core symptom of Major Depressive Disorder (MDD), manifests as a lack or loss of motivation as reflected by decreased reward responsiveness, at both behavioral and neural (i.e., striatum) levels. Exposure to stressful life events is another important risk factor for MDD. However, the mechanisms linking reward-deficit and stress to MDD remain poorly understood. Here,...

Computational analysis of deep visual data for quantifying facial expression production

Leo, Marco ; Carcagnì, Pierluigi ; Distante, Cosimo ; Mazzeo, Pier Luigi ; Spagnolo, Paolo ; Levante, Annalisa ; Petrocchi, Serena ; Lecciso, Flavia

In: Applied sciences, 2019, vol. 9, no. 21, p. 4542

The computational analysis of facial expressions is an emerging research topic that could overcome the limitations of human perception and get quick and objective outcomes in the assessment of neurodevelopmental disorders (e.g., Autism Spectrum Disorders, ASD). Unfortunately, there have been only a few attempts to quantify facial expression production and most of the scientific literature ...

Multimodal communication in aphasia: perception and production of co-speech gestures during face-to-face conversation

Preisig, Basil C. ; Eggenberger, Noëmi ; Cazzoli, Dario ; Nyffeler, Thomas ; Gutbrod, Klemens ; Annoni, Jean-Marie ; Meichtry, Jurka R. ; Nef, Tobias ; Müri, René M.

In: Frontiers in Human Neuroscience, 2018, vol. 12, p. -

The role of nonverbal communication in patients with post-stroke language impairment (aphasia) is not yet fully understood. This study investigated how aphasic patients perceive and produce co-speech gestures during face-to-face interaction, and whether distinct brain lesions would predict the frequency of spontaneous co-speech gesturing. For this purpose, we recorded samples of conversations...
