[A sensorymotor precursor of the hyperactivity syndrom. Study of a sample of swiss French-speaking children]. / Un précurseur sensorimoteur du syndrome d'hyperactivité - Etude d'un groupe d'enfants de la population romande.

Psychological examination aims at objectifying the key symptoms of hyperactivity, namely the disorders of attention and of the exe-cutive functions (briefly, the activation-inhibition control). The -records of 237 patients, aged 5 to 17 and attending our day clinics between 2004 and 2016, are analyzed retrospectively. 40 cases present an attention-deficit/hyperactivity disorder (ADHD), combined presentation, after DSM-5 criteria. These children and adolescents show not only a typical impulsivity on the computerized test of -attention, but also some deficit in learning to write, a precocious manifestation of their neurodevelopmental disorders. This comorbidity correctly classifies 82.4 % of the hyperactivity and control cases, a quite strong effect in the context of the hard to reach -diagnosis of the ADHD syndrom.

L'examen psychologique vise à objectiver les symptômes clés de l'hyperactivité, à savoir les troubles de l'attention et des fonctions exécutives (en bref, le contrôle activation-inhibition). Les dossiers de 237 patients de nos consultations, âgés de 5 à 17 ans et examinés entre 2004 et 2016, sont analysés rétrospectivement. 40 cas présentent un trouble déficitaire de l'attention avec hyper­activité (TDAH), présentation mixte, selon les critères du DSM-5. Ces ­enfants et adolescents montrent non seulement une impulsivité ­caractéristique aux épreuves informatisées de l'attention, mais aussi un déficit dans l'acquisition de l'écriture, une manifestation précoce de leurs troubles neurodéveloppementaux. Cette association classe correctement 82,4 % des hyper­actifs et des contrôles, un effet fort, vu le diagnostic difficile du syndrome TDAH.

Multi-terminal Josephson junctions as topological matter.

Topological materials and their unusual transport properties are now at the focus of modern experimental and theoretical research. Their topological properties arise from the bandstructure determined by the atomic composition of a material and as such are difficult to tune and naturally restricted to ≤3 dimensions. Here we demonstrate that n-terminal Josephson junctions with conventional superconductors may provide novel realizations of topology in n-1 dimensions, which have similarities, but also marked differences with existing 2D or 3D topological materials. For n≥4, the Andreev subgap spectrum of the junction can accommodate Weyl singularities in the space of the n-1 independent superconducting phases, which play the role of bandstructure quasimomenta. The presence of these Weyl singularities enables topological transitions that are manifested experimentally as changes of the quantized transconductance between two voltage-biased leads, the quantization unit being 4e(2)/h, where e is the electric charge and h is the Planck constant.

Control of Andreev bound state population and related charge-imbalance effect.

Motivated by recent experimental research, we study a superconducting constriction subject to a dc and ac phase bias. We consider the processes whereby the ac drive promotes one quasiparticle from an Andreev bound state to a delocalized state outside the superconducting gap. We demonstrate that with these processes one can control the population of the Andreev bound states in the constriction. We stress an interesting charge asymmetry of these processes that may produce a charge imbalance of accumulated quasiparticles, which depends on the phase.

Evaluation de la dynamique familiale et position depressive familiale: apport des méthodes projectives / Avaliação da dinâmica familiar e posição depressiva familiar: contribuição de métodos projetivos / The assessment of the familial dynamic and the depressive familial position: contributions of projective methods

L'auteur propose de mettre au travail, à partir d'une approche groupale-familiale, les conditions dans lesquelles s'établit, au plan des fonctionnements psychiques, la dynamique familiale. A partir de la notion de position dépressive familiale défendue par l'auteur (Roman, 1999), il s'agira d'appréhender la spécificité de l'économie psychique du groupe familiale. Si la méthode projective autorise une approche du fonctionnement psychique de chaque membre de la famille, il apparaît tout à fait pertinent de mettre en perspective les productions projectives au sein de la famille afin de spécifier la spécificité de la configuration de la position dépressive familiale. La présentation d'une situation clinique permet d'illustrer les propositions théoriques et méthodologiques contenues dans cet article(AU)

O autor propõe trabalhar, a partir de uma aproximação grupal-familiar, as condições sobre as quais se estabelece, no plano de funcionamentos psíquicos, a dinâmica familiar. A partir da noção de posição depressiva familiar defendida pelo autor (Roman, 1999), se tratará de apreender a especificidade da economia psíquica do grupo familiar. Se o método projetivo autoriza uma aproximação do funcionamento psíquico de cada membro da família, torna-se pertinente, então, colocar em perspectiva as produções projetivas no seio da família a fim de especificar a especificidade da configuração da posição depressiva familiar. A apresentação de uma situação clínica permite ilustrar as proposições teóricas e metodológicas contidas neste artigo(AU)

The author suggests to work with a groupal-family approach and with the conditions that the psychical family dynamic are based on. To start with, the family depressive position theory, defended by the author (Roman, 1999), shows groupal-family psychical economy specificities. If the projective method allows a closer view to the family depressive position configuration, thus, it will be important to come up with the projective perspective in the family, in order to specify the specificities of the depressive family configuration. The presentation of a clinical situation illustrates the theoretical and methodological propositions that are shown in this article(AU)

Le lien fraternel dans la groupalité familiale: séparations et catastrophes de symbolisation / Fraternal bonding in family groups: separations and symbolisation´s catastrophes

Les auteurs proposent de considérer la dynamique familiale et les enjeux de transmission au sein du groupe familial à partir de la question du lien fraternel dans un contexte de séparation. Après un rappel des théories fondatrices du groupe et la groupalité familiale dans le champ de la psychanalyse, quelques repères seront proposés en appui sur les méthodes projectives (Rorschach, C.A.T, T.A.T): se dégageront ce que les auteurs nomment des 'catastrophes de symbolisation', dont l´émergence au décours des épreuves projectives témoigne de failles dans la dynamique de transmission au sein de la famille, Enfin, une illustration clinique, à partir de deux situations de fratries, permet de mettre à l´épreuve de la clinique les propositions théoriques et méthodologiques (AU)
