Pluricomplex Green's functions and Fano manifolds

We show that if a Fano manifold does not admit Kahler-Einstein metrics then the Kahler potentials along the continuity method subconverge to a function with analytic singularities along a subvariety which solves the homogeneous complex Monge-Ampere equation on its complement, confirming an expectation of Tian-Yau.Comment: EpiGA Volume 3 (2019), Article Nr.

Lukas: A Novella Revealing Low Socioeconomic Condition as a Risk Factor of Schizophrenia

Recent world crises have caused millions to relocate. However, upon reaching their destination, immigrants often suffer from mental health problems. This work addresses how an immigrant status increases one�s likelihood to develop the early symptoms of schizophrenia and how to recover. It does so by using Blair Wheaton�s theory of the sociogenesis of psychological disorder and a phenomenological and participatory research written by Larry Davidson and his colleagues. It warrants a publication of the phenomenon in a creative form. This novella explores the perspective of Lukas Bertram, a wanted politician who left Earth for the planet of Morael, where he would try to survive amidst discrimination, give up, succumb to schizophrenia, and eventually recover. According to the findings, Lukas� fatalism became the mediating variable between low socioeconomic status and his initial development of schizophrenia. Overcoming fatalism by reestablishing social connection and sense of control, thus, sparked his recovery process

Operational results with fast automatic beam-based LHC collimator alignment

The CERN Large Hadron Collider (LHC) is the largest and highest-energy particle accelerator ever built. It is designed to collide particles at a centre-of-mass energy of 14 TeV to explore the fundamental forces and constituents of matter. Due to the potentially destructive high-energy particle beams, with a total design energy of 362 MJ, the collider is equipped with a series of machine protection systems. The beam cleaning or collimation system is designed to passively intercept and absorb particles at large amplitudes. The cleaning efficiency depends heavily on the accurate positioning of the jaws with respect to the beam trajectory. Beam-based collimator alignment is currently the only feasible technique that can be used to determine the beam centre and beam size at the collimator locations. If the alignment is performed without any automation, it can require up to 30 hours to complete for all collimators. This reduces the beam time available for physics experiments. This article provides a brief recap of the algorithms and software developed to automate and speed up the alignment procedure, and presents the operational results achieved with fast automatic beam-based alignment in the 2011-2013 LHC runs.peer-reviewe

Torsional restraint against elastic lateral buckling

It is well known that a central elastic torsional restraint restricts the lateral buckling shape of an elastic I-beam and increases its elastic flexural-torsional buckling resistance. However, available information on the effects of torsional restraints on elastic buckling are either incomplete, or in some cases inaccurate. This paper investigates the effects of moment distribution and load height on the elastic flexural-torsional buckling of beams with central torsional restraints. The effects of off-center and continuous restraints are also studied, and design approximations and procedures are developed.peer-reviewe

Event-Driven Political Communication and the Preadult Socialization of Partisanship

This study investigates political communication as a mediator of the socializing effects of major political events. We earlier found that presidential campaigns are occasions for increased crystallization of partisan attitudes among adolescents (Sears and Valentino, 1997). But what drives the socialization process during the campaign? Either the campaign saturates the media environment with political information, socializing all adolescents roughly equally, or greater individual exposure to political information is necessary for significant socialization gains during the campaign. The analyses utilize a three-wave panel study of preadults and their parents during and after the 1980 presidential campaign. Here we find that adolescents exposed to higher levels of political communication experience the largest socialization gains, that the socializing effects of political communication are limited to the campaign season, and that communication boosts socialization only in attitude domains most relevant to the campaign. We conclude that both a high salience event at the aggregate level and high individual levels of communication about the event are necessary to maximize socialization gains.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/45491/1/11109_2004_Article_417864.pd

Semi-automatic beam-based alignment algorithm for the LHC collimation system

Full beam-based alignment of the LHC collimation system was a lengthy procedure as the collimators were setup manually. A yearly alignment campaign has been sufficient for now, although in future this may lead to a decrease in the cleaning efficiency if machine parameters such as the beam orbit drift over time. Automating the collimator setup procedure can allow for more frequent alignments, therefore reducing this risk. This paper describes the design and testing of a semi-automatic algorithm as a first step towards a fully automatic setup. Its implementation in the collimator control software and future plans are described.peer-reviewe

Fear, Anger, and Voting for the Far Right: Evidence From the November 13, 2015 Paris Terror Attacks

The conjecture that negative emotions underpin support for far-right politics is common among pundits and scholars. The conventional account holds that authoritarian populists catalyze public anxiety about the changing social order and/or deteriorating national economic conditions, and this anxiety subsequently drives up support for the far right. We propose that while emotions do indeed play an independent causal role in support for farright parties and policies, that support is more likely built upon the public’s anger rather than fear. This article explores the relative impact of fear and anger in reaction to the 2015 Paris terror attacks on the propensity to vote for the French far-right party, the Front National, in the 2015 regional elections. Contrary to conventional wisdom, we find that anger is associated with voting for the Front National, while fear is associated with voting against the Front National. Moreover, anger boosts the Front National vote most powerfully among far-right and authoritarian voters. On the other hand, fear reduces support for the far right among those same groups

Inelastic buckling of steel beams with central torsional restraints

It is well known that a central elastic torsional restraint restricts the lateral buckling shape of an elastic I-beam and increases the elastic flexural-torsional buckling moment. However, the effect of torsional restraints on inelastic buckling has not been studied, and it is not known whether the limiting stiffness for elastic buckling can be applied to beams that buckle inelastically. This paper develops a finite-element model for the inelastic nonlinear flexural-torsional analysis of steel I-beams and uses it to investigate the effects of central elastic torsional restraints on the inelastic flexural-torsional buckling of steel I-beams. It is found that a central elastic torsional restraint increases the inelastic strength of the beam, but that the increase in the inelastic strength decreases as the beam's modified slenderness decreases. The limiting value of the stiffness of a central elastic torsional restraint at which the inelastic strength of the beam is equal to that of the corresponding beam with a rigid restraint is related to the modified slenderness of the beam. For a beam with a low modified slenderness that buckles inelastically the limiting restraint stiffness is much smaller than that for a beam that buckles elastically. For slender beams the moment transferred by a central torsional restraint of the limiting stiffness exceeds the strength design requirement for the restraint implied by Standards Australia's AS4100 as a result of excessive central twist rotation.peer-reviewe

Classification of LHC beam loss spikes using support vector machines

The CERN Large Hadron Collider's (LHC) collimation system is the most complex beam cleaning system ever designed. It requires frequent setups to determine the beam centres and beam sizes at the 86 collimator positions. A collimator jaw is aligned to the beam halo when a clear beam loss spike is detected on a Beam Loss Monitor (BLM) downstream of the collimator. This paper presents a technique for identifying such clear loss spikes with the aid of Support Vector Machines. The training data was gathered from setups held during the first three months of the 2011 LHC run, and the model was tested with data from a machine development period.peer-reviewe
