No full textLychnothamnus longus Choi, 1989 (Fig. 7 G-J) Lychnothamnus longus Choi, 1989: 7-10, pl. 5, figs 1-12. DISTRIBUTION. — Up to now, L. longus has only been found in the Late Priabonian-Earliest Rupelian of the eastern part of the Ebro Basin (Choi 1989; Sanjuan & Martín-Closas 2012; Sanjuan et al. 2012). In the present study, this species was found in the Oristà, Santa Maria d’Oló, Torre Casanova (Moià), Moià, Santpedor and Rubió localities (Tables 2, 3). DESCRIPTION Gyrogonites are medium in size, 450-724 µm high (mean 618 µm), and 380-580 µm in width (mean 464 µm).Ŋey are ellipsoidal to ovoidal in shape with an isopolarity index of 104-180 (mean 130). Ŋe apex is rounded to truncate, in some cases pointed in the centre, and displays a marked apical thinning. Ŋe base shows variable morphology, in some cases elongated to form a broad column, and the basal pore shows a small star-shaped funnel. Ŋe spiral cells, flat to concave, are devoid of ornamentation and separated by prominent sutures, which in some specimens are bicarinate. Seven to ten (frequently eight) convolutions are visible laterally. REMARKS Lychnothamnus longus is very variable in size, shape and calcification. Many populations show a continuous change from small, cylindrical gyrogonites with concave spiral cells to large broadly rounded specimens with flat spiral cells.Published as part of Sanjuan, Josep & Martín-Closas, Carles, 2014, Taxonomy and palaeobiogeography of charophytes from the Upper Eocene- Lower Oligocene of the Eastern Ebro Basin (Catalonia, NE Spain), pp. 385-420 in Geodiversitas 36 (3) on pages 401-402, DOI: 10.5252/g2014n3a3, http://zenodo.org/record/453853

In this novel, the author has written a wide range of genres and very long period of time. A part of the novel is based on documents which recorded at the time of these events. Some parts of the novel were written depending on documents which was described events occurring in 1916 and migrations during these period. Sections of the novel which were describing the events of after migration and back home are entirely the author’s fiction.

Distribuição de euphausiacea (Crustacea) (krill) no Arquipélago de São Pedro e São Paulo
Get PDFDissertação (mestrado) - Universidade Federal de Santa Catarina, Centro de Ciências Biológicas, Programa de Pós-Graduação em Ecologia, Florianópolis, 2012Eufausiáceos podem ter sua distribuição afetada por diversos fatores, como a temperatura, massas d'água e a presença de uma topografia abrupta, como quebras de plataformas continentais e cordilheiras submarinas. O Arquipélago de São Pedro e São Paulo (ASPSP) (0°55'00"N e 29°20'45"W) constitui os picos emersos de uma cadeia de montanha submarina com direção Leste-Oeste pertencente à Cordilheira Meso Atlântica. Este trabalho tem como objetivo descrever a composição e abundância de eufausiáceos do ASPSP, verificando se há variação nictemeral, temporal e em locais com diferentes distâncias e profundidades ao redor do arquipélago. Amostras de plâncton foram coletadas entre abril de 2003 e julho de 2005 em duas diferentes distâncias ao redor do ASPSP, dia e noite, totalizando 96 amostras. Arrastos horizontais superficiais foram realizados utilizando rede cônico-cilíndrica de 50 cm de diâmetro de boca e 200 ?m de malha, com fluxômetro acoplado. Foram identificados 11 espécies e 4 táxons, com destaque para Euphausia spp., Euphausia americana, Stylocheiron carinatum, Thysanopoda spp., T. aequalis e T. tricuspidata. A curva de acumulação de espécies estabilizou com 69 amostras, indicando que todas as espécies presentes em águas superficiais próximas ao ASPSP foram capturadas. Obteve-se média (± EP) da abundância total de 245,38 ± 50,66 ind. o 100 m-3, variando de 4,19 ± 2,09 ind. o 100 m-3 em janeiro de 2005 a 1.918,48 ± 993,78 ind. o 100 m-3 em novembro de 2004. Os resultados mostraram que a interação da migração vertical com a profundidade e a distância em relação ao ASPSP afeta a distribuição dos eufausiáceos e que a temperatura é o fator responsável pela variação temporal
Implementing an artificial synapse and neuron using a Si nanowire ion-sensitive field-effect transistor and indium-gallium-zinc-oxide memristors
No full textIn this study, we implement an artificial synapse and neuron in a single platform by combining a silicon nanowire (SiNW) ion-sensitive field-effect transistor (ISFET), an indium-gallium-zinc-oxide (IGZO) memristor, and a voltage-controlled oscillator (VCO). The chemical and electrical operations of the synapse are emulated using the pH sensor operation of the ISFET and long-term potentiation/short-term plasticity of the IGZO memristor, respectively. The concentration of hydrogen ions in an electrolyte is successfully transformed via a VCO-based neuron into modulation of synaptic strength, i.e., the current of the memristor. It mimics the strength of the synaptic connection modulated by the concentration of the neurotransmitter. Thus, the chemical-electrical signal conversion in chemical synapses is clearly demonstrated. Furthermore, the proposed artificial platform can discriminate the chemical synapse from the electrical synapse and the path of the neuro-signal propagation and that of memorization/update of synaptic strength. This can potentially provide a new insight into the principles of brain-inspired computing that can overcome the bottleneck of the state-of-the-art von-Neumann computing systems
Le Bouvard et Pécuchet d'Henri Ey (1955)
No full textinterprétation historique d'un pastiche de "Bouvard et Pécuchet" de Flaubert, écrit par un psychiatre francais en 1955. Pour accéder à la source: http://flaubert.univ-rouen.fr/article.php?id=25In 1955, psychiatrist Henri Ey (1900-1977) edited a Treaty of Psychiatry (Traité de Psychiatrie) as part of the Medical-Chirurgical Encyclopedia (Encyclopédie Médico-Chirurgicale, EMC, Editions Techniques), gathering more than a hundred collaborators. A large portion of these were from the French psychoanalytic community and psychiatrists affiliated with public psychiatric hospitals, however excluding the main characters of academic neuropsychiatry. At a banquet organized to celebrate the publication of the contributed volume, Henri Ey reads to his guests a parody of Bouvard and Pécuchet by Flaubert. I suggest to grasp this relatively little-known manuscript under the lens of irony. Written in a derisive manner by a psychiastrist mocking the practices and doctrines of his field (from mesmerism to Freudianism), this document may also be appraised as a roman à clef about the balance of powers and struggles for monopoly within a medical profession where dissent is being fueled by distinct professional titles, intellectual itineraries or scientific networks. I will first show that Henri Ey probably relied on the "deux bonshommes" to neutralize any form of criticism against his ambition to be an encyclopedist. Henri Ey's attitude may here be compared with that of Raymond Queneau (1903-1976), at the time director of the Encyclopédie de la Pléiade: he, too, was haunted by the characters of the mad professor and the amateur scientist, and he wrote two prefaces for reissues of Bouvard and Pécuchet. However, Henri Ey's Bouvard and Pécuchet is less evocative of Queneau's stylistic composition than the pugnacity of corporatist manuscripts defending psychiatry. In a second step, I will analyze the status of the burlesque pastiche of an already burlesque work: this text hides an authentic satire featured as a comedy. The author targets a number of real individuals, sometimes named in the text and represented in a grotesque manner. Here, parody appears to be serving persiflage.En 1955 le psychiatre Henri Ey (1900-1977) publie sous sa direction un Traité de Psychiatrie dans la collection de l'Encyclopédie Médico-Chirurgicale (EMC, Editions Techniques), rassemblant autour de lui plus d'une centaine de collaborateurs. Parmi eux, une grande partie des psychanalystes français, avec qui les psychiatres du cadre des hôpitaux psychiatriques publics se répartissent les matières à exposer, tandis que les principaux représentants de la neuropsychiatrie universitaire sont exclus. Lors d'un banquet offert pour fêter la parution de l'ouvrage collectif, Henri Ey fait la lecture à ses hôtes d'une parodie (ou pastiche, voire satire ?) de Bouvard et Pécuchet de Flaubert. Je propose d'appréhender ce document méconnu des historiens par le biais de l'ironie : écrit sur le ton de la dérision par un psychiatre évoquant les pratiques et les doctrines qui prêtent le flan à la moquerie dans sa discipline (du mesmérisme au freudisme), le texte peut aussi se lire comme un roman à clef des rapports de force et des défenses de monopole, dans une profession médicale où les dissensions sont nourries par des titres professionnels, par des itinéraires intellectuels et par des réseaux savants différents. Dans un premier temps, je montrerai qu'à travers l'emprunt des " deux bonshommes ", Henri Ey avait certainement pour but de désamorcer toute critique vis-à-vis de son ambition d'encyclopédiste. On peut comparer à cette occasion la posture d'Henri Ey à celle de l'écrivain Raymond Queneau (1903-1976), directeur de l'Encyclopédie de la Pléiade à la même époque : lui aussi fut hanté par les figures du savant fou et du scientifique amateur et il rédigea deux préfaces pour des rééditions de Bouvard et Pécuchet. Cependant, le Bouvard et Pécuchet d'Henri Ey évoque moins l'exercice de style de Queneau que la pugnacité des textes corporatistes de défense de la psychiatrie. Dans un second temps, il s'agira donc d'analyser le statut de l'imitation burlesque d'une œuvre déjà burlesque : ce texte cache une véritable satire sous le travestissement du comique. L'auteur vise une série de personnes bien réelles, parfois nommées dans le texte et présentées de manière grotesque. La parodie apparaît ici comme mise au service du persiflage
Associations of rest-activity patterns with amyloid burden, medial temporal lobe atrophy, and cognitive impairment
Get PDFBACKGROUND: We sought to investigate the possible associations of rest-activity patterns with cortical amyloid burden, medial temporal lobe (MTL) neurodegeneration, and cognitive function in patients in the early stage of cognitive impairment. METHODS: Rest-activity patterns were assessed in 100 participants (70 with mild cognitive impairment and 30 with mild dementia) using wrist actigraphy. All participants underwent (18)F-flutemetamol positron emission tomography (PET) imaging to quantify cortical amyloid burden, structural brain magnetic resonance imaging (MRI) to quantify MTL grey matter volume, neuropsychological testing, and clinical diagnosis. We used multiple linear regression models adjusted for covariates, including demographics, diabetes, hypertension, depressive symptom, psychotropic medication, sleep medication, weekend effect, and apolipoprotein-epsilon allele status. FINDINGS: After adjusting for possible confounders, we found that the midline estimation of statistic of rhythm (MESOR) associated positively with frontal/executive function (estimate = 1.17, standard error [SE] = 0.37, p = 0.002). The least active 5-h (L5) onset time associated positively with MTL grey matter volume and memory function (estimate = 1.24, SE = 0.33, p = 0.001, and estimate = 3.77, SE = 1.22, p = 0.003, respectively), particularly in amyloid-negative participants. Additional path analysis revealed that MTL grey matter volume partially mediated the association between L5 onset time and memory function in amyloid-negative participants. INTERPRETATION: Decreased MESOR and advanced L5 onset time may be useful as early signs of cognitive decline or MTL neurodegeneration. Furthermore, amyloid pathology may act as a moderator of the relationships between rest-activity patterns, neurodegeneration, and cognitive function.
