    Euphysothrips subramanii (Ramakrishna & Margabandhu) (Figs 1–5) Megaphysothrips subramanii Ramakrishna and Margabandhu, 1939: 25 Described from Mysore in Karnataka State, this species is also recorded in India from Tamil Nadu and West Bengal by Tyagi and Kumar (2016). Specimens in the Natural History Museum, London, from these Indian States have been studied, and these were taken from coffee with “diseased leaves” or specifically in association with Hemileia vastatrix. The field observations quoted above from Timor Leste suggest that this thrips is probably dependent on this rust fungus for its life history.Published as part of Mound, Laurence A., 2018, Euphysothrips: an Old World genus of Thripidae (Thysanoptera) associated with rust fungi (Pucciniales), pp. 447-450 in Zootaxa 4532 (3) on page 449, DOI: 10.11646/zootaxa.4532.3.10, http://zenodo.org/record/261539

We investigate how the architecture of a family of chips influences how it is affected by supply and demand uncertainties. We observe that semiconductor supply chains become fragile, in part, due to single de- mand paths, where one chip can satisfy only one demand. Chip architects can enable multiple paths to satisfy a chip demand, which improves supply chain resilience. Based on this observation, we study composition and adaptation as architectural strategies to improve resilience to volatility and also intro- duce a third strategy of dispersion. These strategies allow multiple paths to satisfy a given chip demand. We develop a model to analyze the impact of these architectural techniques on supply chain costs under different regimes of uncertainties and evaluate what happens when they are combined. We present several interesting and even counter-intuitive observations about the product configurations and market conditions where these interventions are impactful and where they are not. In all, we show that product redesign sup- ported by architectural changes can mitigate nearly half of the losses caused by supply and demand volatility. As far as we know, this is the first such investigation concerning chip architecture

    Lifting Reducible Galois Representations

    No full text
    130 pagesLet pp be an odd prime and qq a power of pp. By the celebrated theorem of Khare and Wintenberger (previously Serre's conjecture), an absolutely irreducible odd 22-dimensional Galois representation ρˉ:GQGL2(Fq)\bar{\rho}:\operatorname{G}_{\mathbb{Q}}\rightarrow \operatorname{GL}_2(\mathbb{F}_q) (satisfying favorable conditions) lifts to a characteristic zero Galois representation associated to a Hecke eigencuspform. Hamblen and Ramakrishna prove the analog of (the weak form of) Serre's conjecture for residually reducible 22-dimensional Galois representations. A higher dimensional generalization of their result is proved in chapter three. Let ρˉ:GQGSp2n(Fq)\bar{\rho}:\operatorname{G}_{\mathbb{Q}}\rightarrow \operatorname{GSp}_{2n}(\mathbb{F}_q) be a reducible and indecomposable Galois representation which is unramified outside a finite set of primes SS and whose image lies in a Borel subgroup. It is shown that if ρˉ\bar{\rho} satisfies some additional conditions, it lifts to characteristic zero Galois representation which is geometric in the sense of Fontaine-Mazur. \par In chapter four, we examine the problem of lifting a two dimensional Galois representation ρˉ:GQ,SGL2(Fq)\bar{\rho}:\operatorname{G}_{\mathbb{Q},S}\rightarrow \operatorname{GL}_2(\mathbb{F}_q) to a cuspidal Hida Family which is isomorphic to the Iwasawa algebra Λ\Lambda via the weight-space map. This was achieved for an odd, ordinary and absolutely irreducible ρˉ\bar{\rho} by Ramakrishna for a suitable choice of auxiliary local deformation conditions. We show that if ρˉ\bar{\rho} is reducible and indecomposable, one may indeed lift ρˉ\bar{\rho} to a Hida family T\mathbb{T} such that the image of the weight space map contains a congruence class of weights in SpecΛ\operatorname{Spec} \Lambda modulo p2p^2. This Hida family is in some sense close to SpecΛ\operatorname{Spec} \Lambda, more precisely, we show that it represents a deformation functor which is arranged to have a hull isomorphic to SpecΛ\operatorname{Spec} \Lambda (this isomorphism is not via the weight-space map). In chapter five, we apply results of Hamblen-Ramakrishna to construct some special Galois extensions. For every prime p5p\geq 5 for which a certain condition on the class group Cl(Q(μp))\operatorname{Cl}(\mathbb{Q}(\mu_p)) is satisfied, we construct a pp-adic analytic Galois extension of the infinite cyclotomic extension Q(μp)\mathbb{Q}(\mu_{p^{\infty}}) with some special ramification properties. In greater detail, this extension is unramified at primes above pp and tamely ramified above finitely many rational primes and its Galois group over Q(μp)\mathbb{Q}(\mu_{p^{\infty}}) is isomorphic to a finite index subgroup of SL2(Zp)\operatorname{SL}_2(\mathbb{Z}_p) which contains the principal congruence subgroup. For the primes 107,139,271107,139,271 and 379379 such extensions were first constructed by Ohtani and Blondeau. The strategy for producing these special extensions at an abundant number of primes is through lifting two-dimensional reducible Galois representations which are diagonal when restricted to pp.Soit pp un nombre premier impair et qq une puissance de pp. Par le célèbre théorème de Khare et Wintenberger (auparavant la conjecture de Serre), une représentation galoisienne absolument irréductible de 22 ρˉ:GQGL2(Fq)\bar{\rho}:\operatorname{G}_{\mathbb{Q}}\rightarrow \operatorname{GL}_2(\mathbb{F}_q) (satisfaisant à des conditions favorables) se lève vers une représentation galoisienne caractéristique associée à un eigencuspform de Hecke. Hamblen et Ramakrishna prouvent l'analogue de (la forme faible de) la conjecture de Serre pour les représentations galoisiennes à 22 -dimensionnelles résiduellement réductibles. Une généralisation dimensionnelle supérieure de leur résultat est démontrée au chapitre trois. Soit ρˉ:GQGSp2n(Fq)\bar{\rho}:\operatorname{G}_{\mathbb{Q}}\rightarrow \operatorname{GSp}_{2n}(\mathbb{F}_q) une représentation galoisienne réductible et indécomposable qui est non ramifié en dehors d'un ensemble fini de nombres premiers SS et dont l'image se trouve dans un sous-groupe Borel. Il est montré que si ρˉ\bar{\rho} remplit certaines conditions supplémentaires, il passe à une représentation galoisienne caractéristique zéro qui est géométrique au sens de Fontaine-Mazur. \par Dans le chapitre quatre, nous examinons le problème de la levée d'une représentation galoisienne bidimensionnelle ρˉ:GQ,SGL2(Fq)\bar{\rho}:\operatorname{G}_{\mathbb{Q},S}\rightarrow \operatorname{GL}_2(\mathbb{F}_q) à une famille Hida cuspidale qui est isomorphe à l'algèbre Iwasawa Λ\Lambda via la carte de l'espace de poids. Ceci a été réalisé pour un ρˉ\bar{\rho} impair, ordinaire et absolument irréductible par Ramakrishna pour un choix approprié de conditions de déformation locale auxiliaire. Nous montrons que si ρˉ\bar{\rho} est réductible et indécomposable, on peut en effet soulever ρˉ\bar{\rho} dans une famille Hida T\mathbb{T} de telle sorte que l'image de la carte d'espace de poids contienne une classe de congruence de poids dans SpecΛ\operatorname{Spec} \Lambda modulo p2p^2. Cette famille Hida est en quelque sorte proche de SpecΛ\operatorname{Spec} \Lambda, plus précisément, nous montrons qu'elle représente un foncteur de déformation qui est arrangé pour avoir une coque isomorphe à SpecΛ\operatorname{Spec} \Lambda (ce l'isomorphisme ne se fait pas via la carte poids-espace). Dans le chapitre cinq, nous appliquons les résultats de Hamblen-Ramakrishna pour construire des extensions Galois spéciales. Pour chaque p5p\geq 5 premier pour lequel une certaine condition du groupe de classes Cl(Q(μp))\operatorname{Cl}(\mathbb{Q}(\mu_p)) est satisfaite, nous construisons une extension galois analytique pp -adic de l'extension cyclotomique infinie Q(μp)\mathbb{Q}(\mu_{p^{\infty}}) avec quelques propriétés de ramification spéciales. Plus en détail, cette extension n'est pas ramifiée aux nombres premiers supérieurs à pp et se ramifie tamely au-dessus d'un nombre fini de nombres premiers rationnels et de son groupe de Galois sur Q(μp)\mathbb{Q}(\mu_{p^{\infty}}) est isomorphe à un sous-groupe d'index fini de SL2(Zp)\operatorname{SL}_2(\mathbb{Z}_p) qui contient le sous-groupe de congruence principal. Pour les nombres premiers 107,139,271107,139,271 et 379379, de telles extensions ont d'abord été construites par Ohtani et Blondeau. La stratégie pour produire ces extensions spéciales à un nombre abondant de nombres premiers consiste à lever les représentations galoisiennes bidimensionnelles réductibles qui sont diagonales lorsqu'elles sont limitées à pp

    Ramakrishna: a clinical investigation of mystical experience

    No full text
    Este estudo busca questionar algumas das bases epistemológicas da psicologia clínica em relação à espiritualidade e à mística. Partindo da discussão entre Freud e o escritor Francês Romain Rolland a respeito do sentimento oceânico (baseado na correspondência entre eles no período de 1927 a 1931), abordaremos a compreensão da natureza ontológica da experiência de união com o universo (como descrito por Rolland) em um duplo vértice: tanto como um subproduto de dinâmicas psicológicas (inerentemente patológicas ou não) ou como uma experiência ontológica de alteridade, mais bem compreendida através de uma abordagem não psicológica que possa investigar seu significado em consonância ao registro da condição humana em si. Nessa última perspectiva, estaremos acompanhados da obra de Gilberto Safra, que em seus escritos evidencia uma preocupação com a busca de uma concepção antropológica que aborde o ser humano em toda sua complexidade, evitando o possível reducionismo psicológico de temas e áreas que possam se relacionar a outras categorias de experiência, como a religiosidade e a espiritualidade. Como eixo central dessa discussão, utilizaremos a vida do místico Indiano Ramakrishna Paramahansa (1836-1886) para ilustrar esses diferentes modos de se abordar a experiência espiritual. Ramakrishna foi uma das principais fontes das construções de Rolland acerca da religiosidade, levando o autor francês a escrever uma de suas principais biografias (A vida de Ramakrishna, 1929), que teve um importante impacto na recepção ocidental de concepções espirituais orientais. Contemplando exemplos da vida de Ramakrishna, através de uma leitura fenomenológica-hermenêutica da obra de Rolland (que abarcam desde sua infância até seu período como um famoso mestre espiritual na Índia), será apresentado, em cada um desses períodos, diferentes perspectivas de autores que consideram Ramakrishna tanto em uma chave psicológica-psicopatológica quanto em uma abordagem que inclua um registro espiritual não redutível a dinâmicas psíquicas em sua vida. Dentro desse estudo, nós percebemos que há uma limitação inerente às leituras exclusivamente psicológicas das experiências místicas, assim como uma há uma limitação das leituras exclusivamente espiritualistas. Assim, ao apresentar tal discussão nós pretendemos repensar a posição que a espiritualidade e a mística ocupam na prática clínica, tanto para reformular sua compreensão em psicoterapia quanto para expandir as concepções éticas e antropológicas subjacentes ao entendimento clínico da condição humanaThis study aims at questioning some of the epistemological basis of clinical psychology concerning mystical experience and spirituality. Focusing on the discussion between Freud and French author Romain Rolland regarding the oceanic feeling (based on their letters exchange from 1927 to 1931), we will question the comprehension of the ontological nature of the feeling of union with the universe (as described by Rolland) through a twofold bias: either as a by-product of psychological dynamics (inherently pathological or not) or as an ontological experience of alterity, better comprehended through a non-psychological approach that investigates its inner meaning regarding the human condition as such. In the latter perspective, we will be accompanied by the work of Brazilian author Gilberto Safra, whose clinical writings are concerned with an anthropological conception that approaches the human being in its own complexity, avoiding possible psychological reductionism of themes and issues that relate to other areas of experience, such as religiosity and spirituality. As the main axis of this discussion, we will utilize the life of Indian mystic Ramakrishna Paramahansa (1836-1886) to illustrate these two different ways of approaching spiritual experience. Ramakrishna has been himself one of the main sources of Rollands constructions on religiosity, leading the French author to write one of his main biographies (The life of Ramakrishna, 1929), which had an important impact on Western reception of Eastern spiritual conceptions. Contemplating examples from Ramakrishnas life through a phenomenological-hermeneutical reading of Rollands work (that range from his childhood to his period as a famous spiritual master in India), we will present, in each situation, different perspectives from authors that either consider Ramakrishna exclusively on a psychological-psychopathological note or through a perception of a spiritual dimension non-reducible to psychical dynamics inherent to his life and teachings. Within this framework, we have come to realize that there are inherent limitations on a solely psychological reading of mystical experience, as well as a limitation on an exclusively spiritual approach. Therefore, by presenting such discussion we intend to rethink the position mysticism and spirituality occupy in clinical practice, both to reformulate their understanding in psychotherapy and as a way of enlarging the anthropological conceptions inherent to clinical understanding of the human conditio
