No full textخلاصة •يُعيد المؤلّف النظر في دراسة وُضِعَت حول نص يأتي على ذكر حملة الملك أسرحدّون ضدّ صيدا عام ٦٦٧ ق. م. فيقترح توقيع المدن والقرى المذكورة في النص في أماكن تختلف عن تلك التي سبق لبعض الباحثين اقتراحها. الأمر الذي يمكّن من تحديد حدود مملكة صيدا في تلك الأيام ضمن دائرة يتراوح شعاعها بين ٢٠ و ٣٠ كلم وبمساحة تبلغ حوالي ألف كيلومتر مربّع عوضاً عن توسيعها على طول الساحل اللبناني من صور جنوباً إلى طرابلس شمالاً.The author revises the study of a text relating Asarhaddon’s campaign against Sidon in 677 BC. After revisiting and discussing the identification of certain toponyms mentionned in this text, he proposes new ones. He then establishes that the Kingdom of Sidon at the time of Asarhaddon was not extented from Tyre in the south to Tripoli in the north, as some scholars proposed, but was limited to some one thousand square kilometres around the city.L’auteur reprend l’étude d’un récit de la campagne d’Asarhaddon contre Sidon en 677 av. J.-C. Il remet en question l’identification d’un certain nombre de toponymes mentionnés dans ce texte et en propose d’autres. On peut dès lors constater que le Royaume de Sidon à l’époque d’Asarhaddon, loin de couvrir un espace compris entre Tyr au sud et Tripoli au nord, comme certains l’ont cru, se limitait en fait à un espace compris dans un rayon de 20 à 30 km au grand maximum autour de la ville, et s’étendait en gros sur un millier de kilomètres carrés.Salame-Sarkis Hassan.

Heterotic compactifications with flux
No full textWe study various aspects of heterotic compactifications with torsion. We de- fine and compute the dressed elliptic genus associated to Fu-Yau compactifications, and use this result to compute one-loop threshold corrections to various BPS-saturated cou- plings in the four-dimensional effective supergravity action. Finally, we study non-compact supersymmetric solutions which generalize, among others, the known heterotic solutions on the conifold.Nous étudions différents aspects liés aux compactifications hétérotiques avec torsion. Nous définissons et calculons le genre elliptique vêtu associé aux compactifications Fu-Yau, et exploitons ce résultat pour calculer les corrections de seuil à une boucle de différents couplages BPS-saturés dans l’action effective de supergravité à quatre dimen- sions. Enfin nous nous intéressons à des solutions supersymétriques non-compactes qui généralisent, entre autres, les solutions hétérotiques connues sur le conifold
Le dieu de Râs ach-Chaq‘a-Théouprosopon
No full textخلاصة •بعد دراسة شناخ رأس الشقعة الذي عُرِف في العصور الكلاسيكيّة باسم شناخ وجه الله، وبعد استعراض النصوص التي جاءت على ذكره، منذ العصور القديمة حتّى الحديثة، يقترح المؤلف أنّ هذا الشناخ هو عينه الذي ورد اسمه في حوليّات شلمناصر الثالث تحت ومن خلال الاعتماد على المستندات الإيقونوغرافية، لا سيّما منها المنقوشات المسكوكاتيّة، يقترح المؤلّف أيضاً اعتبار. «

اسم إله البترون، وبالتالي إله رأس وجه الله، تجلّياً من تجلّيات إله الرعود والبروق والخصوبة الكونيّة العظيم. كما يقترح أن إيقونوغرافيّة هذا الإله وطقوس عبادته قد انتشرت في مناطق البقاع ولبنان الشمالي على إثر سيطرة العرب الإيطوريّين عليها.After a geographic description of the promontory of Râs ach-Chaq‘ a, the Theouprosopon of the Ancients, and an inventory of the texts that mention it under various appellations from the Antiquity to the contemporary period, the author proposes to recognize it as the Ba‘ li Ra’si of the Annals of Salmanasar III. Backing up on iconographic documents, particulary on coins, he proposes to recognize the god of Batrun, and therefore the god of the Theouprosopon, as an avatar of the great storm-god and cosmic fertility, whose iconography and cult had been propagated by the Itureans in the regions that they have controled in the north of the Beqa‘ and the north of Lebanon.Après une description géographique du promontoire de Râs ach-Chaq‘ a, le Théouprosopon des Anciens, et une recension des textes qui le mentionnent sous diverses appellations depuis l’Antiquité jusqu’à l’époque contemporaine, l’auteur propose d’y reconnaître le Ba‘ li Ra’si des Annales de Salmanasar III. S’appuyant sur des documents iconographiques, particulièrement des monnaies, il propose de reconnaître dans le dieu de Batroun, et partant le dieu du Théouprosopon, un avatar du grand dieu de l’orage et de la fécondité cosmique, dont l’iconographie et le culte ont dû être propagés par les Ituréens dans les régions qu’ils ont dominées dans le nord de la Béqa‘ et le nord du Liban.Salame-Sarkis Hassan.

Dressed elliptic genus of heterotic compactifications with torsion and general bundles
No full textInternational audienceWe define and compute the dressed elliptic genus of N = 2 heterotic com-pactifications with torsion that are principal two-torus bundles over a K3 surface. We consider a large class of gauge bundles compatible with supersymmetry, consisting of a stable holomorphic vector bundle over the base together with an Abelian bundle over the total space, generalizing the computation previously done by the authors in the absence of the latter. Starting from a (0,2) gauged linear sigma-model with torsion we use supersym-metric localization to obtain the result. We provide also a mathematical definition of the dressed elliptic genus as a modified Euler characteristic and prove that both expressions agree for hypersurfaces in weighted projective spaces. Finally we show that it admits a natural decomposition in terms of N = 4 superconformal characters, that may be useful to investigate moonshine phenomena for this wide class of N = 2 vacua, that includes K3 × T 2 compactifications as special cases
Fine-scale genetic mapping using independent component analysis
No full textThe aim of genetic mapping is to locate the loci responsible for specific traits such as complex diseases. These traits are normally caused by mutations at multiple loci of unknown locations and interactions. In this work, we model the biological system that relates DNA polymorphisms with complex traits as a linear mixing process. Given this model, we propose a new fine-scale genetic mapping method based on independent component analysis. The proposed method outputs both independent associated groups of SNPs in addition to specific associated SNPs with the phenotype. It is applied to a clinical data set for schizophrenia, with 368 individuals and 42 SNPs. It is also applied to a simulation study to investigate its performance in more depth. The obtained results demonstrate the novel characteristics of the proposed method compared to other genetic mapping methods. Finally, we study the robustness of the proposed method with missing genotype values and limited sample sizes. © 2008 IEEE.Akey JM, 2001, AM J HUM GENET, V68, P1447, DOI 10.1086-320607; Alter O, 2003, P NATL ACAD SCI USA, V100, P3351, DOI 10.1073-pnas.0530258100; Balding D, 2001, HDB STAT GENETICS; Cardon LR, 2001, NAT REV GENET, V2, P91, DOI 10.1038-35052543; CHURCHILL GA, 1994, GENETICS, V138, P963; Collett D., 2002, MODELLING BINARY DAT; COMON P, 1994, SIGNAL PROCESS, V36, P287, DOI 10.1016-0165-1684(94)90029-9; Dawy Z, 2006, IEEE ACM T COMPUT BI, V3, P47, DOI 10.1109-TCBB.2006.9; GABRIEL KR, 1979, TECHNOMETRICS, V21, P489, DOI 10.2307-1268288; Hoh J, 2003, NAT REV GENET, V4, P701, DOI 10.1038-nrg1155; Hoh J, 2001, GENOME RES, V11, P2115, DOI 10.1101-gr.204001; Horne BD, 2004, GENET EPIDEMIOL, V26, P11, DOI 10.1002-gepi.10292; Hudson RR, 2002, BIOINFORMATICS, V18, P337, DOI 10.1093-bioinformatics-18.2.337; Hyvaerinen A., 2001, INDEPENDENT COMPONEN; Hyvarinen A, 1999, IEEE T NEURAL NETWOR, V10, P626, DOI 10.1109-72.761722; KAISER HF, 1958, PSYCHOMETRIKA, V23, P187, DOI 10.1007-BF02289233; Kooperberg C, 2005, GENET EPIDEMIOL, V28, P157, DOI 10.1002-gepi.20042; Liebermeister W, 2002, BIOINFORMATICS, V18, P51, DOI 10.1093-bioinformatics-18.1.51; Liu L, 2003, P NATL ACAD SCI USA, V100, P13167, DOI 10.1073-pnas.1733249100; Machado AMC, 2004, IEEE SIGNAL PROC MAG, V21, P20, DOI 10.1109-MSP.2004.1296539; McPeek MS, 1999, AM J HUM GENET, V65, P858, DOI 10.1086-302537; Morris AP, 2000, AM J HUM GENET, V67, P155, DOI 10.1086-302956; Mueller JC, 2005, ANN NEUROL, V57, P535, DOI 10.1002-ana.20438; Nelson MR, 2001, GENOME RES, V11, P458, DOI 10.1101-gr.172901; NOTHNAGEL M, 2002, AM J HUMAN GENETICS, V71; Oba S, 2003, BIOINFORMATICS, V19, P2088, DOI 10.1093-bioinformatics-btg287; SARKIS M, 2006, P IEEE INT C IM PROC; Schaid DJ, 2002, AM J HUM GENET, V70, P425, DOI 10.1086-338688; SHWARTZ S, 2004, P 5 INT C IND COMP A; Cordero JF, 2002, AM J HUM GENET, V70, P1; Troyanskaya O, 2001, BIOINFORMATICS, V17, P520, DOI 10.1093-bioinformatics-17.6.520; Zaykin DV, 2002, HUM HERED, V53, P79, DOI 10.1159-000057986; Zee R.

El uso del instrumento armado en Latinoamérica: entre lo tradicional y no convencional. Los casos de Chile y México
No full textThe following text performs a theoretical evaluation of the military heterogeneity in Latin America, taking into consideration several features as military planning, foreign policy, defense policy, and migration controls, amongst others. In order to do so, the author studies the cases of Chile and Mexico: the former orientatesits military towards democratic stability and humanitarian intervention, while the latter uses it to tackle down the “narcoguerrilla” and organized crime. Both cases offer examples of the military diversity among the region and the conceptual variations of the military functions, going from the most conventional objectives -protection and defense, internal security- to more recent ones -support and implementation of foreign policies-
Threshold corrections in heterotic flux compactifications
No full textInternational audienceWe compute the one-loop threshold corrections to the gauge and gravitational couplings for a large class of non-Kähler heterotic compactifications with three-form flux, consisting in principal two-torus bundles over K3 surfaces. We obtain the results as sums of BPS-states contributions, depending on the topological data of the bundle. We analyse also the worldsheet non-perturbative corrections coming from instantons wrapping the torus fiber, that are mapped under S-duality to D-instanton corrections in type I flux compactifications
Modeling noncovalent interatomic interactions on a photonic quantum computer
No full texteditorial reviewedNoncovalent interactions are a key ingredient to determine the structure, stability, and dynamics of materials, molecules, and biological complexes. However, accurately capturing these interactions is a complex quantum many-body problem, with no efficient solution available on classical computers. A widely used model to accurately and efficiently model noncovalent interactions is the Coulomb-coupled quantum Drude oscillator (cQDO) many-body Hamiltonian, for which no exact solution is known. We show that the cQDO model lends itself naturally to simulation on a photonic quantum computer, and we calculate the binding energy curve of diatomic systems by leveraging Xanadu's strawberry fields photonics library. Our study substantially extends the applicability of quantum computing to atomistic modeling by showing a proof-of-concept application to noncovalent interactions, beyond the standard electronic-structure problem of small molecules. Remarkably, we find that two coupled bosonic QDOs exhibit a stable bond. In addition, our study suggests efficient functional forms for cQDO wave functions that can be optimized on classical computers, and capture the bonded-to-noncovalent transition for increasing interatomic distances
