Observation of the Decay $K_L\to μ^+μ^- γγ$
A. Alavi-Harati
Physics , 2000, DOI: 10.1103/PhysRevD.62.112001
Abstract: We have observed the decay $K_L\to \mu^+\mu^- \gamma \gamma$ at the KTeV experiment at Fermilab. This decay presents a formidable background to the search for new physics in $K_L\to\pi^0\mu^+\mu^-$. The 1997 data yielded a sample of 4 signal events, with an expected background of 0.155 $\pm$ 0.081 events. The branching ratio is ${\mathcal B}(K_L\to \mu^+\mu^- \gamma \gamma$) $ = (10.4^{+7.5}_{-5.9} {\rm (stat)} \pm 0.7 {\rm (sys)})\times 10^{-9}$ with $m_{\gamma\gamma} \geq 1 {\rm MeV/c}^2$, consistent with a QED calculation which predicts $(9.1\pm 0.8)\times 10^{-9}$.
Search for the Decay $K_L \to π^0 μ^+ μ^-$
A. Alavi-Harati
Physics , 2000, DOI: 10.1103/PhysRevLett.84.5279
Abstract: We report on a search for the decay \klpimumu carried out as a part of the KTeV experiment at Fermilab. This decay is expected to have a significant $CP$ violating contribution and a direct measurement will either support the CKM mechanism for CP violation or point to new physics. Two events were observed in the 1997 data with an expected background of $0.87 \pm 0.15$ events, and we set an upper limit \BR{\klpimumu} $ <3.8 \times 10^{-10}$ at the 90% confidence level.
Branching Ratio Measurement of the decay K_L -> e+ e- mu+ mu-

Physics , 2001, DOI: 10.1103/PhysRevLett.87.111802
Abstract: We have collected a 43 event sample of the decay $K_L\to e^+e^-\mu^+\mu^-$ with negligible backgrounds and measured its branching ratio to be $(2.62 \pm 0.40 \pm 0.17)\times 10^{-9} $. We see no evidence for CP violation in this decay. In addition, we set the 90% confidence upper limit on the combined branching ratios for the lepton flavor violating decays $K_L\to e^{\pm}e^{\pm}\mu^{\mp}\mu^{\mp}$ at ${\mathcal B}(K_L\to e^{\pm}e^{\pm}\mu^{\mp}\mu^{\mp}) \leq 1.23\times10^{-10}$, assuming a uniform phase space distribution.
Search for the Decay K_L -> pi^0 nu nubar using pi^0 -> e^+ e^- gamma
A. Alavi-Harati
Physics , 1999, DOI: 10.1103/PhysRevD.61.072006
Abstract: We report on a search for the decay K_L -> pi^0 nu nubar, carried out as a part of E799-II, a rare K_L decay experiment at Fermilab. Within the Standard Model, the K_L -> pi^0 nu nubar decay is dominated by direct CP violating processes, and thus an observation of the decay implies confirmation of direct CP violation. Due to theoretically clean calculations, a measurement of B(K_L -> pi^0 nu nubar) is one of the best ways to determine the CKM parameter eta. No events were observed, and we set an upper limit B(K_L -> pi^0 nu nubar) < 5.9 times 10^-7 at the 90% confidence level.
Oedipal Identity of the Patriarch in Gabriel Garcia Marquez’s The Autumn of The Patriarch
Maryam Harati,Fatemeh Sadat Basirizadeh
Canadian Social Science , 2011, DOI: 10.3968/j.css.1923669620110705.174
Abstract: In his masterpiece –The Autumn of the Patriarch- G. G. Marquez describes the death and the life of a dictator having no name, living more than 200 years in an unknown island. Marquez’s literary creation of such dictator whose power overshadowed the whole universe, even the sun and the moon, provides an opportunity of psychoanalytic study. Sigmund Freud’s psychological theory especially Oedipus complex and unconscious crises seem to be appeared in the dictator’s character and his relationship with other characters in the novel. The most noticeable one is the sort of relationship exists between the dictator and his mother. Sigmund Freud (1856-1939) believes that human personality consists of three parts called the Id, Ego and the Superego. Id, Ego and Superego are together called an energy system, a kind of sexual energy which Freud believes to be the motivations of what all humans do - Libido. The Oedipus complex that Freud gets its name from an ancient Greek drama (tragedy) by Sophocles called Oedipus the Rex in which Oedipus kills his father and marries his mother; it contains a sort of psychological conflict between the child’s id and the superego. Based on what Freud tells about the Oedipus complex, the researchers try to find the oedipal identity of the dictator in The Autumn of the Patriarch. Key words: Id; Ego; Superego; Oedipus complex and Libido Résumé Dans son chef-d' uvre L'Automne du patriarche de l'Marquez-GG décrit la mort et la vie d'un dictateur ayant pas de nom, vivant à plus de 200 ans dans une le inconnue. La création littéraire Marquez du dictateur dont la puissance éclipsée ces tout l'univers, même le soleil et la lune, fournit une occasion d'étude psychanalytique. Théorie psychologique de Sigmund Freud en particulier les crises complexe d' dipe et de l'inconscient semble être apparu dans le caractère du dictateur et de sa relation avec les autres personnages dans le roman. La plus notable est le genre de relation existe entre le dictateur et sa mère. Sigmund Freud (1856-1939) estime que la personnalité humaine se compose de trois parties appelées l'Id, moi et le surmoi. Id, moi et du surmoi sont ensemble appelé un système énergétique, une sorte d'énergie sexuelle que Freud croit être les motivations de ce que tous les humains ne - Libido. Le complexe d' dipe que Freud obtient son nom d'un drame antique grec (tragédie) de Sophocle Oedipe appelé le Rex dans lequel dipe tue son père et épouse sa mère, il contient une sorte de conflit psychologique entre l'ID de l'enfant et le surmoi. Basé sur ce que Freud parle du complexe d' dipe, l
Fiction ou réalité : Les biographies de Constance Fenimore Woolson Fiction or Non-Fiction? Constance Fenimore Woolson’s Biographies
Jeannine Hayat
Revue LISA / LISA e-journal , 2005, DOI: 10.4000/lisa.619
Abstract: Constance Fenimore Woolson (1840-1894) was an American novelist, famous toward the end of the 19th century. She was educated in the Great Lakes region, and her familiarity with the frontier gave her many subjects for her first stories published, among others, in Harper’s New Monthly Magazine and in the Atlantic Monthly. In 1873 she moved to Florida and began to feel inspired by the South, the Reconstruction after the war and the racial problem. She discovered Europe in 1880 and she met with Henry James in Florence. A strange friendship between the Master and the popular woman writer was to last until 1894. Leon Edel, Henry James’s biographer, supposed she felt an unrequited love for him. New feminist studies assert she was, on the contrary, independent and never asked literary figures for their help. Did she commit suicide or fall from a window by accident? Nobody knows. Contemporary novelists like David Lodge, Colm Toibin or Emma Tennant are puzzled by her relationship with Henry James.
The Relationship between Weight as Well as the Kind of Prostate Hypertrophy and the Response to Tamsulosine, a Specific ?-Blocker
Hayat Mombini
Urology Journal , 2004,
Abstract: Purpose: To study the effects of Tamsulosine (Flowmax) as a specific ?-blocker in patients with prostate weighted less than 40 g and lacked median lobe and to compare them to patients with prostate weighted more than 40 g with median lobe. Materials and Methods: Forty outpatients with BPH were referred to clinic and intentionally enrolled in this study. Patients were divided into 2 groups of 20 patients. Tamsulosine was daily administered for all of them for 6 weeks. Routine tests were performed for all patients, all of which were normal. The probability of prostate cancer was ruled out. The size of prostate and type of hypertrophy were determined by one radiologist via DRE, suprapubic ultrasonography and TRUS-P. Patients were divided into A and B groups according to the size of prostate and the lack of median lobe or its presence. Prostate size was less than 40 mg in group A and all patients lacked median lobe; whereas, prostate size was more than 40 mg (between 40-60 mg) in group B and patients had some median lobe. Results: An increase of 30% in base line Q Max and a decrease of 25% in base line IPSS was seen in 16 patients (80%) of group A, while these were observed only 9 patients (45%) of group B. Conclusion: Determination of prostate size and the type of hypertrophy seems to be essential before any Tamsulosine administration. The weight of prostate is determined by protoscan.
Lytton Strachey : l’historien intime de deux reines Lytton Strachey’s Intimate Biographies of Two Queens
Jeannine Hayat
Revue LISA / LISA e-journal , 2007, DOI: 10.4000/lisa.646
Abstract: The British writer Lytton Strachey (1880-1932) wrote biographies of the two most eminent Queens of England: Queen Victoria (1921) and Elizabeth and Essex (1928). The two books made him a very famous historian. However, he would personally have preferred to be admired for his poetry or his plays, for he was a very gifted literary author. Nevertheless many of Strachey’s readers have appreciated his conception of biography, as a means of personal confession while studying the destiny of a public figure. Indeed the Stracheyan way of life, free from Victorian moral standards and guided by the rules of the Bloomsbury group, inspired his story of Victoria and Elizabeth. Both Queens at the end of their lives and at the height of their power carried on strange love affairs: Victoria with her Scottish gillie and Elizabeth with the Earl of Essex, thirty years her younger. In fact, both romances subtly reflect Strachey’s own love affairs. He was himself engaged in a kind of common life with Dora Carrington— the painter, thirteen years younger than him, with whom he was not sexually involved— while he engaged in numerous homosexual love affairs.
Gardiston le vieux de Constance Fenimore Woolson Old Gardiston by Constance Fenimore Woolson
Jeannine Hayat
Revue LISA / LISA e-journal , 2007, DOI: 10.4000/lisa.629
Abstract: Gardiston le vieux était un manoir des rizières, situé à dix kilomètres d’un port du Sud. On désignait ainsi le batiment depuis soixante ou soixante-dix ans, ce qui prouve qu’il datait au moins du dix-huitième siècle. Après cette époque, il n’aurait pu se prévaloir de ce titre honorable, dans une région où la Déclaration d’Indépendance était encore considérée comme un événement relativement moderne. La guerre était terminée, et la ma tresse de maison, mademoiselle Margaretta Gardiston, reposa...
