Possible non-decoupling effects of heavy Higgs bosons in e+ e- -> W+ W- within THDM

We discuss the origin of the nondecoupling effects of the heavy Higgs bosons within the two Higgs doublet extension (THDM) of the Standard Model (SM) and illustrate it by means of the one-loop calculation of the differential cross-sections of the process e+ e- -> W+ W- in both the decoupling and the non-decoupling regimes. We argue that there are many regions in the THDM parametric space in which the THDM and SM predictions differ by several percents and such effects could, at least in principle, be testable at the future experimental facilities.Comment: 8 pages, 2 figures; to appear soon in EPJC. v2 - several minor corrections (typos), references adde

Transient dynamics of linear quantum amplifiers

The transient dynamics of a quantum linear amplifier during the transition from damping to amplification regime is studied. The master equation for the quantized mode of the field is solved, and the solution is used to describe the statistics of the output field. The conditions under which a nonclassical input field may retain nonclassical features at the output of the amplifier are analyzed and compared to the results of earlier theories. As an application we give a dynamical description of the departure of the system from thermal equilibrium.Comment: 10 pages, 6 figures. V2: extended discussion on application

Some Classes Of Semigroups That Have Medial Idempotent And Some Construction Theorem

It's known that the set of idempotents of the semigroup, plays an important role forthe structure of this semigroup. Specially, in the regular semigroups, an importantrole plays presence of the medial idempotent and normal medial idempotent.Blyth,T. S and R. B. McFadden have studied and constructed the regular semi groups which contain a normal medial idempotent in terms of idempotent-generated regular semi groups with a normal medial idempotent and inverse semigroups with anidentity. M.Loganathan has described the construction of the regular semigroupswhich contain a medial idempotent. In this paper we will study further properties of medial idempotents on abundant semigroups. We will apply also the constructiontheory of abundant semigroups with a medial idempotent to quasi-adequate semigroups and will make a description of structure of those subsemigroups

Voice: Voting and Political Expression in the Gulf

Democracy depends on the ability of all people to participate in the public dialogue. Without the ability to express viewpoints and have them represented in government, individuals cannot exercise political power to help shape their community and country.Many displaced residents of the Gulf Coast region are finding it difficult in the wake of Hurricanes Katrina and Rita to express their viewpoints and participate in the political process. Early evidence finds that many groups -- including racial and ethnic minorities and low-income families -- have struggled to vote in post-hurricane elections and to have a say in the region's reconstruction plans. These problems mirror national trends, but also suggest that another unfortunate legacy of the hurricanes of 2005 could be an erosion of voice among those communities whose political expression was most endangered prior to the storms. Without their diverse viewpoints, the region's reconstruction risks suffering from insularity and a failure to reap the benefits of pluralism. Voice is therefore an important element of opportunity for those most victimized by Katrina.This fact sheet summarizes research on the political participation of vulnerable Gulf Coast communities after Katrina, as well as national trends in electoral participation. It draws on this research to identify obstacles to political participation, and offers recommendations for means to expand voice for all

An Ordinal factor analysis of requirements and challenges of information and communication technology system to train private agricultural insurance brokers in Iran

This study was conducted to identify challenges and requirements of an information and communication technology (ICT) system to train brokers. Using the ordinal factor analysis, the challenges and requirements have been classified into six factors (Human, Organisational, Technical,Social, Financial, and Legal) and four factors (instructional,technical, organisational, and cultural) respectively. Finally a conceptual framework is presented for the challenges and requirements of the ICT training system

Genetic Algorithm for Orthogonal Designs

We show how to use Simple Genetic Algorithm to produce Hadamard matrices of large orders, from teh full orthogonal design or oder 16 with 9 variables, OD(16; 1, 1, 2, 2, 2, 2, 2, 2, 2). The objective functionthat we use in our implementation of Simple Genetic Algorithm, comes from a Computational Algebra formalism of the full orthogonal design equations. In particular, we constructed Hadamard matrices of orders 144, 176, 208, 240, 272, 304 and 336, from the aforementioned orthogonal design. By varying three genetic operator parameters, we computer 62 inequivalent Hadamard matices of order 304 and 4 inequivalent Hadamard matrices of order 336. Therefore we established two new constructive lower bounds for the numbers of Hadamard matrices of order 304 and 336

Mumpsimus and Sumpsimus : the intellectual origins of a Henrician bon mot

Henry VIII's appearance before the assembled houses of parliament on Christmas Eve 1545 was perhaps his finest hour. In what has been called a ‘pioneer royal Christmas broadcast’, the king delivered an impassioned and eloquent speech lamenting the religious divisions that afflicted his kingdom, and urging his subjects towards unity and charity. 1 According to William Petre, the king himself wept as he recounted how ‘charity between man and man is so refrigerate’, and few of his audience could restrain themselves from doing likewise. 2 Another eye-witness, the chronicler Edward Hall, wrote down the speech ‘worde for worde, as near as I was able to report it’. This account gives details of how Henry illustrated the breakdown of fraternal love among his people: ‘the one calleth the other Hereticke and Anabaptist, and he calleth hym again, Papist, Yypocrite and Pharisey’; rival preachers inveighed against each other ‘without charity or discrecion’. To the king's mind, the blame for this deserved to be apportioned to all sides, and, to reinforce the point, Henry brought forward one of the more curious metaphors of contemporary religious discourse: ‘some be to styff in their old Mumpsimus, other be to busy and curious in their newe Sumpsimus’. 3 Recent historians of the reign have understandably devoted considerable attention to his speech, arguably the most famous of all Henry VIII's public pronouncements, and most have quoted the mumpsimus–sumpsimus idiom, with varying degrees of wry amusement. 4 Yet there has been little attempt to explain why the king should use precisely these words to epitomise the polarisation of religious positions in the early 1540s. 5 It is not always apparent from modern accounts that the terms ‘mumpsimus’ and ‘sumpsimus’ did not represent the king's own assay at faux-bucolic neologism, but were an established (though not long-established) literary trope. In the following short discussion, I hope to demonstrate how an investigation of the derivation and precedents of the phraseology employed by Henry in his Christmas speech can throw some revealing light on the processes by which religious typologies were constructed and utilised in the course of the Henrician Reformation, as well as providing some points of orientation in that most formidable of terrae incognitae, the mind of Henry VIII himself. 6 -------------------------------------------------------------------------------- Footnotes 1 The phrase is Diarmaid MacCulloch's: Thomas Cranmer: a life, New Haven–London 1996, 348. 2 PRO, SP 1/212, fos 110v–11r (Letters and papers, foreign and domestic, of the reign of Henry VIII, ed.

Detection of Intra-day Variability Timescales of Four High Energy Peaked Blazars with XMM-Newton

We selected a sample of 24 XMM-Newton light curves (LCs) of four high energy peaked blazars, PKS 0548-322, ON 231, 1ES 1426+428 and PKS 2155-304. These data comprise continuous light curves of 7.67h to 18.97h in length. We searched for possible quasi-periodic oscillations (QPO) and intra-day variability (IDV) timescales in the LCs of these blazars. We found a likely QPO in one LC of PKS 2155-304 which was reported elsewhere (Lachowicz et al. 2009). In the remaining 23 LCs we found hints of possible weak QPOs in one LC of each of ON 231 and PKS 2155-304, but neither is statistically significant. We found IDV timescales that ranged from 15.7 ks to 46.8 ks in 8 LCs. In 13 LCs any variability timescales were longer than the length of the data. Assuming the possible weak QPO periods in the blazars PKS 2155-304 and ON 231 are real and are associated with the innermost portions of their accretion disk, we can estimate that their central black hole masses exceed 1.2 $\times$ 10$^{7}$ M$_{\odot}$. Emission models for radio-loud active galactic nuclei (AGN) that could explain our results are briefly discussed.Comment: 13 emulateapj pages, 2 tables, 4 figures, accepted for publication in The Astrophysical Journa
