Invariance of the parity conjecture for p-Selmer groups of elliptic curves in a D2pnD_{2p^n}-extension

In section 2, we show a $p$-parity result in a $D_{2p^{n}}$-extension of number fields $L/K$ ($p\geq 5$) for the twist $1\oplus \eta \oplus \tau$: W(E/K,1\oplus \eta \oplus \tau)=(-1)^{}, where $E$ is an elliptic curve over $K,$ $\eta$ and $\tau$ are respectively the quadratic character and an irreductible representation of degree 2 of $Gal(L/K)=D_{2p^{n}},$ and $X_{p}(E/L)$ is the $p$-Selmer group. The main novelty is that we use a congruence result between $$-factors (due to Deligne) for the determination of local root numbers in bad cases (places of additive reduction above 2 and 3). We also give applications to the $p$-parity conjecture (using the machinery of the Dokchitser brothers).Comment: 19 page

Hain Friswell.: https://www.gutenberg.org/ebooks/9105In a distinctive and polished series of short aphorisms, La Rochefoucauld explores the oddities of human nature and how they affect our use of moral categories to understand the behavior of ourselves and others

EHPAD et marque employeur, le couple gagnant ?

Le nombre de personnes âgées augmente avec le vieillissement de la population occasionnant une sollicitation croissante des EHPAD. Toutefois, certains établissements doivent faire face à des problématiques d’attractivité et peine à recruter du personnel pour permettre le bon fonctionnement de l’organisation alors que la tendance se dirige vers une augmentation des besoins. La marque employeur, intégrée à la stratégie RH des entreprises, est communément utilisée attirer les candidats et leur offrir un cadre de travail motivant. De là, l’idée de développer une marque employeur dans ces établissements pour pallier à ces difficultés ne semble pas incohérente. La problématique de ce travail exploratoire est de savoir en quoi la marque employeur peut atténuer un manque d’attractivité au sein des EHPAD. Ainsi, à travers une méthodologie qualitative, ce sont dix directeurs d’établissement d’EHPAD de la région Centre Val-de-Loire qui se sont exprimés au cours d’entretiens individuels semi-directifs. Les résultats démontrent une capacité pour les EHPAD à développer une marque employeur, tant dans une démarche d’attractivité des potentiels candidats que dans une dynamique fidélisant les collaborateurs. En finalité, les EHPAD au sein de notre population ayant une marque employeur développée présenteraient un taux de turn-over faible ou modéré et  une  problématique  d’attractivité  réduite. &nbsp

A mathematical model of the circle of Willis in the presence of an arteriovenous anomaly

AbstractThis paper deals with a complete model of the flow in the Willis circle and its vicinity. We study: (a) the normal case; and (b) the influence of the presence of an arteriovenous anomaly. We have simulated the therapeutic procedures in order to confirm the treatment

Is there more room to negotiate with the IMF on fiscal policy?

This repository item contains a working paper from the Boston University Global Economic Governance Initiative. The Global Economic Governance Initiative (GEGI) is a research program of the Center for Finance, Law & Policy, the Frederick S. Pardee Center for the Study of the Longer-Range Future, and the Frederick S. Pardee School of Global Studies. It was founded in 2008 to advance policy-relevant knowledge about governance for financial stability, human development, and the environment.During the 1980s the IMF emerged as a global “bad cop,” demanding harsh austerity measures in countries faced with debt problems. Has the Great Recession changed all that? Is there more room to negotiate with the Fund on fiscal policy? The answer is yes. If we take a close look at what the IMF researchers say and what its most influential official reports proclaim, then we can see that there has been a more “Keynesian” turn at the Fund. This means that today one can find arguments for less austerity, more growth measures and a fairer social distribution of the burden of fiscal sustainability. The IMF has experience a major thaw of its fiscal policy doctrine and well‐informed member states can use this to their advantage. These changes do not amount to a paradigm shift, a la Paul Krugman’s ideas. Yet crisis‐ridden countries that are keen to avoid punishing austerity packages can exploit this doctrinal shift by exploring the policy implications of the IMF’s own official fiscal doctrine and staff research. They can cut less spending, shelter the most disadvantaged, tax more at the top of income distribution and think twice before rushing into a fast austerity package. This much is clear in all of the Fund’s World Economic Outlooks and Global Fiscal Monitors published between 2009 and 2013 with regard to four themes: the main goals of fiscal policy, the basic options for countries with fiscal/without fiscal space, the pace of fiscal consolidation, and the composition of fiscal stimulus and consolidation

Guest Editors' Introduction

‘I shall have to speak of things, of which I cannot speak’, writes Samuel Beckett in The Unnameable, ‘but also, which is even more interesting, but also that I, which is if possible even more interesting, that I shall have to, I forget, no matter’. Listening to the voice of folly can be like this: an endless flow of inconsistencies, of contradictions, sayings and unsayings; a tantalising, mischievous mockery of speech –unable to go on, unable to end. And yet – as this volume shows – we are irresistibly drawn to folly, its promises, its whispers of ‘even more interesting’ things: of how we are split between conscious and unconscious, familiar and unfamiliar, same and other. For psychoanalysis, folly is not only a site of hidden truths; it is also, perhaps more importantly, a source of unconscious freedom, a momentary escape from our obsession with rules and order. According to Christopher Bollas, the unconscious self is like a fool, who ‘raises potentially endless questions about diverse and disparate issues’ and thereby provides us with a ‘separate sense’, which opens us to others and to our own creative potential. As Rachel Bowlby elegantly puts it, folly is a ‘soul-mole’, forever shovelling our secrets out into the light: ‘there’s no possible moment of release or resignation when the mole might stop vainly, interminably working away’. Folly’s subversive, creative soliloquies reveal to us a psychic ‘underground repertoire of secrets’; they challenge our established knowledge and invite us, as Bolwby shows, to endless, titillating games of ‘suppression and confession’. For Anne Duprat, this deep-seated playfulness explains folly’s close relation to fiction: what makes them so atone is their ‘capacity of creating alternative representations of the world — and thus of re-figuring the world depicted by reason or history – […] but also their paradoxical structure, and hence the instability of their speech acts, which deny, suspend, or do not seriously guarantee the truth of their statements’.

Emulation of X-ray Light-Field Cameras

X-ray plenoptic cameras acquire multi-view X-ray transmission images in a single exposure (light-field). Their development is challenging: designs have appeared only recently, and they are still affected by important limitations. Concurrently, the lack of available real X-ray light-field data hinders dedicated algorithmic development. Here, we present a physical emulation setup for rapidly exploring the parameter space of both existing and conceptual camera designs. This will assist and accelerate the design of X-ray plenoptic imaging solutions, and provide a tool for generating unlimited real X-ray plenoptic data. We also demonstrate that X-ray light-fields allow for reconstructing sharp spatial structures in three-dimensions (3D) from single-shot data
