Esmail Khois Rueckkehr nach Borgio Verezzi. [Esmail Khois' Return to Borgio Verezzi]
No full textEsmail Khoi’s poem Return to Borgio Verezzi (written in March 1983 and first published in 1984) belongs to the key texts of post-revolution Persian exile literature. Esmail Khoi is one of the leading voices of Persian poetry in the second half of the 20th century. His literary works since the beginning of his exile in London in 1982 include more than 20 books of poetry, translations of classical Persian literature (particularly the 14th century satirical poet Obey-e Zakani of Shiraz) into English and numerous articles and contributions to Iranian press in exile. Khoi was a founding member of the Iranian Writers’ Association and the Iranian PEN Center in exile. In 1989, after the annoncement of Ayatollah Khomeini’s fatwa (death sentence) against the British author Salman Rushdie, Khoi was among the founding members of the international committee for the defence of Salman Rushdie. Return to Borgio Verezzi is a long narrative poem which reflects many key aspects and features of Khoi’s work and personality as a modern poet with strong ties to the tradition of classical Persian poetry and as a politically and socially engaged exile. My paper consists of an introductory essay about the poem. Initially it uses the methodology of “explication de texte” with a text immanent approach. In the further development of the essay the historical and intertextual references to the poetry of Hafis, Forugh Farrokhzad and Nasser-e Khosro are also discussed. The essay is followed by my translation of the poem into German. The booklet is accompanied by an audio CD with an original recoding of Esmail Khoi reading his poem in Persian. Literary critics generally consider Esmail Khoi as one of the best voices to recite poetry by himself and also by other classical and modern Persian poets
Sharpening the A→Z(∗)h signature of the type-II 2HDM at the LHC through advanced machine learning
No full textThe A→Z(∗)h decay signature has been highlighted as possibly being the first testable probe of the Standard Model (SM) Higgs boson discovered in 2012 (h) interacting with Higgs companion states, such as those existing in a 2-Higgs Doublet Model (2HDM), chiefly, a CP-odd one (A). The production mechanism of the latter at the Large Hadron Collider (LHC) takes place via bb¯-annihilation and/or gg-fusion, depending on the 2HDM parameters, in turn dictated by the Yukawa structure of this Beyond the SM (BSM) scenario. Among the possible incarnations of the 2HDM, we test here the so-called Type-II, for a twofold reason. On the one hand, it intriguingly offers two very distinct parameter regions compliant with the SM-like Higgs measurements, i.e., where the so-called `SM limit' of the 2HDM can be achieved. On the other hand, in both configurations, the AZh coupling is generally small, hence the signal is strongly polluted by backgrounds, so that the exploitation of Machine Learning (ML) techniques becomes extremely useful. Ours approach in this respect is a three-prong one. Firstly, we adjust ML models to analyze all possible High Energy Physics (HEP) data types, so as to maximize the amount of input information. Secondly, unlike most `black-box' ML approaches currently in use in the HEP community, we exploit a (linear) Centered Kernel Alignment (CKA) similarity metric to analyze the learned representations in the hidden layers, thereby enabling an interpretative element of our results. Thirdly, we emphasise that the proposed ML models are generic and can thus be adopted in other physics problems. Concerning the one at hand, by using such advanced ML implementations, we ultimately show that the sensitivity of LHC searches in the l+l−bb¯ (l=e,μ) final state can significantly be improved with respect to traditional cut-and-count analyses and/or, et
Inscriptions of Piety and Coptic Saints in Old Cairo (Fustat)
No full textAn artifact in the Keir Collection of Islamic Art, a double-sided folio with saintly drawings of
haloed figures and inscriptions in Coptic and Arabic, is the subject of this paper. The artifact has
not been researched before and except for the brief catalogue entry in the Keir Collection
Catalogue, the author did not find any secondary scholarship on this artifact. It has been grouped
within the label of “Fustat Fragments,” and has not been studied closely in relation to the
drawings and the inscriptions, nor have the identities of the figures of the drawings been
accurately determined. The informal quality of the line drawings and rough, hastily penned
inscriptions raise interesting questions on the nature and purpose of this object. Through a close
analysis of the visual, textual and the physical characteristics of the fragment, this paper attempts
to answer some questions raised. The questions pertain to the identification of the figures, the
stylistic and iconographical elements of the illustrations, the content of the inscriptions, the
literary corpus they originate from and, whether the fragment belonged within a manuscript, as
well as the time period and historical context of its production. The study identifies the figures as
the equestrian martyr Saint George and the Archangel Michael, who are widely venerated in
Coptic Christianity as protectors and intercessors. The inscriptions have been identified as
consisting of biblical passages and extracts from psalms contained within the Agpeya, the book
of hours of Coptic (Egyptian) Christians. For the Coptic Christians, the religiosity and reverence
that the figures of Saint George and Archangel Michael inspire, the roles that define them, and
the narratives that they are associated with, make them objects of devotion and power. The
narratives emerging in the illustrations relate to the ideas of the triumph of goodness over evil,
intercession between God and mankind and protection from adversities of life and safe passage
into eternity. The discussion throws light on the Coptic painting traditions and iconographical
programs that promoted the saintly narratives, and the styles that were in use in the Premodern
period, such as the Akhmim Style from Upper Egypt, as well as the artists that propagated the
art. The translation and analysis of the biblical content of the inscriptions, which contain
invocations to Christ and Virgin Mary, brings into play the literary tradition pertaining to
religious texts, the historical context of Copto-Arabic literature, the preservation of religious
texts through manuscripts production, and the role of the monasteries in this area of activity

Developmental influences of thyroid hormones on the rat olfactory receptor sheet
No full textAlthough much is known about the regulatory role of thyroid hormones on brain development, little is known about the effects of thyroid hormones on the development of the peripheral nervous system. The major aim of this thesis therefore, is to examine the role of thyroid hormones on the postnatal development of the olfactory receptor sheet (epithelium) of the rat. Quantitative, light microscopic morphometric and cell count studies were carried out on the olfactory epithelium of growing normal, hypothyroid, hypothyroid/recovery and hyperthyroid rats to measure olfactory neuronal proliferation and maturation.Our results have found that hypothyroidism during early postnatal development results in partial suppression of olfactory neuronal proliferation and maturation, while prolonged hypothyroidism resulted in complete suppression of epithelial growth. Thus, hypothyroidism led to significant reductions in the normal accretion of olfactory neurons. Unlike thyroid deficiency, hyperthyroidism was found to have no significant effect on olfactory neuronal proliferation or maturation.Animals rehabilitated from hypothyroidism at weaning showed a resumption of epithelial growth such that by the age of 90 days, the deficits in neuronal number were completely overcome, while the number of mature neurons showed substantial but incomplete recovery. These results show that unlike central neural structures, the olfactory epithelium of the rat retains the ability to recover from early hypothyroid retardation.Made available in DSpace on 2011-05-07T12:59:40Z (GMT).

No full text In the fall of 1996, FORUM published an article by S. W. Ng, R. Esmail, W. J. Sibbald and G. S. Doig. The title of the article was “Potential savings involved in the purchase of low cost, high volume medical commodities as established from a community hospital survey.” ( Healthcare Management FORUM 1996;9[4]:24–29.) Gordon S. Doig was mistakenly described in the author biography as Gordon S. Doig, DVM, MSc, PhD. At the time of publication, Mr. Doig was in fact a PhD candidate and had not yet achieved his PhD. Mr. Doig's correct academic title (in both 1996 and as of today) is Gordon S. Doig, BSc, DVM, MSc. FORUM apologizes for any inconvenience this error might have caused him. </jats:p
Are you sitting comfortably? The political economy of the body
No full textThe aim of this paper is to examine the relationship between the mass production of furniture in modern industrial societies and lower back pain (LBP). The latter has proven to be a major cost to health services and private industry throughout the industrialised world and now represents a global health issue as recent WHO reports on obesity and LBP reveal. Thus far there have been few co-ordinated attempts to deal with the causes of the problem through public policy. Drawing upon a range of sources in anthropology, health studies, politics and economics, the paper argues that this a modern social problem rooted in the contingent conjuncture of natural and social causal mechanisms. The key question it raises is: what are the appropriate mechanisms for addressing this problem? This paper develops an analysis rooted in libertarian social theory and argues that both the state and the capitalist market are flawed mechanisms for resolving this problem. There remains a fundamental dilemma for libertarians, however. Whilst the state and the market may well be flawed mechanisms, they are the dominant ones shaping global political economy. To what extent can libertarians work within these structures and remain committed to libertarian goals
The Effect of Residential Investment on Nearby Property Values: Evidence from Cleveland, Ohio
No full textThis study analyzes the effect of both new and rehabilitation residential investment on nearby property values in Cleveland, Ohio. The methodology used is hedonic price regression with spatial lagged variables that are generated applying geographic information systems. There are four major findings. First, the effect of investment on property values is geographically limited. Second, new investment has a greater impact on nearby property values than rehabilitation. Third, there is evidence that new construction and rehabilitation have a significantly positive impact in low-income areas, as well as predominantly non-minority neighborhoods. Finally and most importantly, the research suggests that small-scale investment has no impact on nearby property values. Thus, investment policy, which promotes and encourages investments that are not sufficiently large, may not be able to improve tax bases and enhance neighborhoods. We also found that results could be misleading if spatial lagged variables are inappropriately measured.

Retinitis Pigmentosa GTPase Regulator (RPGR) protein isoforms in mammalian retina:insights into X-linked Retinitis Pigmentosa and associated ciliopathies
No full textMutations in the cilia-centrosomal protein Retinitis Pigmentosa GTPase Regulator (RPGR) are a frequent cause of retinal degeneration. The RPGR gene undergoes complex alternative splicing and encodes multiple protein isoforms. To elucidate the function of major RPGR isoforms (RPGR 1-19 and RPGR ORF15), we have generated isoform-specific antibodies and examined their expression and localization in the retina. Using sucrose-gradient centrifugation, immunofluorescence and co-immunoprecipitation methods, we show that RPGR isoforms localize to distinct sub-cellular compartments in mammalian photoreceptors and associate with a number of cilia-centrosomal proteins. The RCC1-like domain of RPGR, which is present in all major RPGR isoforms, is sufficient to target it to the cilia and centrosomes in cultured cells. Our findings indicate that multiple isotypes of RPGR may perform overlapping yet somewhat distinct transport-related functions in photoreceptors
