title: On Principle of the Director General Personal Liability of a Business Company
Creators: name: Абакумова, Екатерина Борисовна

description: Статья посвящена проблеме привлечения к гражданско-правовой ответственности единоличного исполнительного органа хозяйственного общества за убытки, причиненные в результате совершения сделки, одобренной общим собранием участников (акционеров). Автором обоснована необходимость освобождения директора от ответственности при согласовании сделки решением высшего органа управления, кроме случаев: а) если общее собрание одобрило очевидно невыгодную для хозяйственного общества сделку; б) если директор скрыл от участников какие-либо детали сделки или изменил ее условия впоследствии; в) если будут доказаны иные факты умышленного нарушения директором интересов общества.
description: The article is devoted to the problem of bringing the sole executive body of a business company to civil legal liability for losses caused by a transaction approved by the general meeting of participants (shareholders). The author substantiates the need to release the director from liability in cases of approving a transaction by the decision of the supreme management body, with the following exceptions: a) if the general meeting approved an obviously unfavorable for the business company transaction; b) if the director concealed any details of the transaction from the participants or changed its terms later; c) if other justifications of intentional violation of the company's interests executed by the director are proved.

description: We compute the shear viscosity of a superfluid atomic Fermi gas in the unitarity limit. The unitarity limit is characterized by a divergent scattering length between the atoms, and it has been argued that this will result in a very small viscosity. We show that in the low temperature T limit the shear viscosity scales as xi^5/T^5, where the universal parameter 'xi' relates the chemical potential and the Fermi energy, mu=xi E_F. Combined with the high temperature expansions of the viscosity our results suggest that the viscosity has a minimum near the critical temperature T_c. A naive extrapolation indicates that the minimum value of the ratio of viscosity over entropy density is within a factor of ~ 5 of the proposed lower bound hbar/(4πk_B).

We also look for previously unknown variability and discover a nova. We discuss an observing strategy for an extended campaign with the goal of determining whether MACHOs exist or whether all microlensing events are compatible with lens stars in M31.

description: I study the zero-temperature phase behavior of bosonic particles living on the nodes of a regular spherical mesh ("Platonic mesh") and interacting through an extended Bose-Hubbard Hamiltonian. Only the hard-core version of the model is considered here, for two instances of Platonic mesh. Using the mean-field decoupling approximation, I show that the system may exist in various ground states, which can be regarded as analogs of gas, solid, supersolid, and superfluid. For one mesh, by comparing the theoretical results with the outcome of numerical diagonalization, I manage to uncover the signatures of diagonal and off-diagonal spatial orders in a finite quantum system.

Use of 2D N.M.R. and bacteriophages in structural studies of some E. coli antigens
Creators: name: Kuma-Mintah, Agyeman
Publisher: name: University of British Columbia
Year: 2010

description: The capsular polysaccharide of Escherichia coli K31 has been found by methylation analysis and n.m.r. spectroscopy to be based on the hexasaccharide shown. The sequence of the repeating unit was deduced from the combined results of β-elimination, lithium ethylenediamine degradation, and hydrogen fluoride and selective hydrolyses. The nature of the anomeric linkages, established by chromic acid oxidation, was confirmed by ¹Hcoupled ¹³C-n.m.r. spectroscopy. Two dimensional n.m.r. studies on a low molecular weight polymer obtained by bacteriophage depolymerization confirmed the structure given below. [See Thesis for Diagram] The importance of bacteriophage-borne enzymes in the generation of lower polymers very suitable for homonuclear (¹H) two dimensional n.m.r. studies is demonstrated. E. coli K33 has been shown to cross react with Klebsiella K58. Chemical and two-dimensional n.m.r. studies gave the K antigen of E. coli K33 as a tetrasaccharide repeating unit [See Thesis for Diagram] and this structure is quite identical to that of Klebsiella K58. The use of homonuclear two-dimensional ¹H-spin correlated n.m.r. experiment as a very convenient method for the location of acetate in the repeating unit of a polysaccharide is illustrated using E. coli K33 polysaccharide as an example. The identification of a phosphate ester in the repeating unit of E. coli K46 using n.m.r. spectroscopy is reported. Detailed n.m.r. study on this antigen is well documented in this communication. The first occurrence of a 3,6-dideoxyamino sugar residue in an E. coli K antigen (i.e. E. coli K45 K antigen) and the finger print of its proton chemical shifts is also shown.
Reexamination of entanglement of superpositions

description: We find tight lower and upper bounds on the entanglement of a superposition of two bipartite states in terms of the entanglement of the two states constituting the superposition. Our upper bound is dramatically tighter than the one presented in Phys. Rev. Lett 97, 100502 (2006) and our lower bound can be used to provide lower bounds on different measures of entanglement such as the entanglement of formation and the entanglement of subspaces. We also find that in the case in which the two states are one-sided orthogonal, the entanglement of the superposition state can be expressed explicitly in terms of the entanglement of the two states in the superposition.

SpookyNet: Learning Force Fields with Electronic Degrees of Freedom and Nonlocal Effects

description: Machine-learned force fields (ML-FFs) combine the accuracy of ab initio methods with the efficiency of conventional force fields. However, current ML-FFs typically ignore electronic degrees of freedom, such as the total charge or spin state, and assume chemical locality, which is problematic when molecules have inconsistent electronic states, or when nonlocal effects play a significant role. This work introduces SpookyNet, a deep neural network for constructing ML-FFs with explicit treatment of electronic degrees of freedom and quantum nonlocality. Chemically meaningful inductive biases and analytical corrections built into the network architecture allow it to properly model physical limits. SpookyNet improves upon the current state-of-the-art (or achieves similar performance) on popular quantum chemistry data sets. Notably, it is able to generalize across chemical and conformational space and can leverage the learned chemical insights, e.g. by predicting unknown spin states, thus helping to close a further important remaining gap for today's machine learning models in quantum chemistry.
QCD thermodynamics and confinement from a dynamical quasiparticle point of view
Creators: name: Cassing, W.
Publisher: name: arXiv
Year: 2007
Subjects: subject: Nuclear Theory (nucl-th)
subject: FOS: Physical sciences

description: In this study it is demonstrated that a simple picture of the QCD gluon liquid emerges in the dynamical quasiparticle model that specifies the active degrees of freedom in the time-like sector and yields a potential energy density in the space-like sector. By using the time-like gluon density (or scalar gluon density) as an independent degree of freedom - instead of the temperature $T$ as a Lagrange parameter - variations of the potential energy density lead to effective mean-fields for time-like gluons and an effective gluon-gluon interaction strength at low density. The latter yields a simple dynamical picture for the gluon fusion to color neutral glueballs when approaching the phase boundary from a temperature higher than $T_c$ and paves the way for an off-shell transport theoretical description of the parton dynamics.

description: The effect of energy absorption during the binary evolution of Exotic-compact-objects (ECOs) is extensively studied. We review the underlying mechanism that provides the energy dissipation in material objects - tidal friction. We show that unlike typical astrophysical objects, where absorption due to viscosity is negligible, in ECOs, absorption could potentially mimic the analogous effect of black-holes (BHs) - tidal heating. We stand for their differences and similarities in the context of energy dissipation during the inspiral. Inspired by the membrane paradigm and recent studies, we demonstrate how viscosity is a defining feature that quantifies how close is the ECO absorption to that of a classical BH absorption. We show that for ECOs, viscosity can induce significant modifications to the GW waveform, which in some favorable scenarios of super-massive binaries of equal mass and spin, enables the measurement of the ECO absorption in the future precision gravitational-wave (GW) observations. Finally, we discuss the implications on the ECO reflection coefficient and the relation to the universal viscosity to volume entropy bound.

Superexchange induced canted ferromagnetism in dilute magnets

Subjects: subject: Disordered Systems and Neural Networks (cond-mat.dis-nn)

description: We argue, in contrast to recent studies, that the antiferromagnetic superexchange coupling between nearest neighbour spins does not fully destroy the ferromagnetism in dilute magnets with long-ranged ferromagnetic couplings. Above a critical coupling, we find a \textit{canted} ferromagnetic phase with unsaturated moment. We have calculated the transition temperature using a simplified local Random Phase Approximation procedure which accounts for the canting. For the dilute magnetic semiconductors, such as GaMnAs, using \textit{ab-initio} couplings allows us to predict the existence of a canted phase and provide an explanation to the apparent contradictions observed in experimental measurements. Finally, we have compared with previous studies that used RKKY couplings and reported non-ferromagnetic state when the superexchange is too strong. Even in this case the ferromagnetism should remain essentially stable in the form of a canted phase.

description: L’enseignement de la lecture aux élèves en situation de déficience intellectuelle et avec des besoins de communication complexes représente un défi pour les enseignants spécialisés et n’est que peu étudié. Cette étude de cas uniques, effectuée avec trois élèves pendant environ trois mois sur la base d’une version adaptée de la méthode ELODI, a pu mettre en évidence l’importance d’un enseignement adapté à cette population. Il est ainsi nécessaire de réaliser un enseignement systématique et explicite d’un degré d’intensité suffisante, de répéter certaines leçons, de prendre en compte le délai constant, d’apporter des feedbacks systématiques, d’utiliser des renforcements positifs, d’offrir des étayages (modélisation notamment), d’évaluer régulièrement les élèves de manière formative, d’introduire la leçon d’apprentissage par une explication et de la terminer par une récapitulation, et utiliser la technique de décodage en trois étapes. En adaptant l’enseignement de la lecture avec des modalités de réponse par pointage ou en disant les sons « dans la tête », les élèves avec DI et BCC s’améliorent dans leurs compétences phonologiques, dans l’apprentissage de correspondance graphèmes-phonèmes, dans leurs compétences en décodage de syllabes. De plus, ils peuvent être en émergence de plusieurs éléments, comme l’encodage ou le décodage de mots. Les bénéfices de l’apprentissage de la lecture sont nombreux, que ce soit au niveau des futurs apprentissages, de leur estime de soi ou encore au niveau de leur future qualité de vie sociale et professionnelle.
Thermal evolution of Uranus and Neptune II -- Deep thermal boundary layer

Subjects: subject: Earth and Planetary Astrophysics (astro-ph.EP)

description: Thermal evolution models suggest that the luminosities of both Uranus and Neptune are inconsistent with the classical assumption of an adiabatic interior. Such models commonly predict Uranus to be brighter and, recently, Neptune to be fainter than observed. In this work, we investigate the influence of a thermally conductive boundary layer on the evolution of Uranus- and Neptune-like planets. This thermal boundary layer (TBL) is assumed to be located deep in the planet, and be caused by a steep compositional gradient between a H-He-dominated outer envelope and an ice-rich inner envelope. We investigate the effect of TBL thickness, thermal conductivity, and the time of TBL formation on the planet's cooling behaviour. The calculations were performed with our recently developed tool based on the Henyey method for stellar evolution. We make use of state-of-the-art equations of state for hydrogen, helium, and water, as well as of thermal conductivity data for water calculated via ab initio methods. We find that even a thin conductive layer of a few kilometres has a significant influence on the planetary cooling. In our models, Uranus' measured luminosity can only be reproduced if the planet has been near equilibrium with the solar incident flux for an extended time. For Neptune, we find a range of solutions with a near constant effective temperature at layer thicknesses of 15 km or larger, similar to Uranus. In addition, we find solutions for thin TBLs of few km and strongly enhanced thermal conductivity. A $\sim$ 1$~$Gyr later onset of the TBL reduces the present $ΔT$ by an order of magnitude to only several 100 K. Our models suggest that a TBL can significantly influence the present planetary luminosity in both directions, making it appear either brighter or fainter than the adiabatic case.

Preparation and some chemistry of ethyl 2,3-bis(alkylidene)cyclobutanecarboxylates
Creators: name: Lu, Yee-Fung

Year: 2010

description: This thesis describes the preparation and some chemistry of the cyclobutanecarboxylates 9. Syntheses of larger ring homologs of 9 (compounds and 11) are also presented. Deconjugation-alkylation of ethyl (Z)- and (E)-3-trimethylstannyl-2-alkenoates 1 and 2 with alkylating agents of general structure 7 affords the (Z)-3-trimethylstannyl-3-alkenoates (see 8), respectively. The diene esters 8a efficient intramolecular palladium(0)-catalyzed cross coupling reactions of the halide and vinylstannane groups to provide the cyclobutanecarboxylates the diene esters 8b and 8c were converted into the coupled products respectively. A number of Diels-Alder reactions of the cyclobutanecarboxylates structurally related substances are described. These studies provided regarding the relative reactivities of various substrates of general structure face-, regio- and stereoselectivities of the Diels-Alder processes. The reactions led to the preparation of the bicyclic cyclobutenes 314 and Alder reactions were also performed on the diene 318 to provide cyclobutenes 319 and 321. The bicyclic cyclobutenes 322, 324 and 327 readily prepared from the keto esters 314 and 315. The stereochemistry of the thermally induced, conrotatory ring reaction of each of the bicyclic cyclobutenes 314, 315, 319, 321, 322, 327 was investigated. Thermolysis of 319, 321 and 322 gave, in each product resulting from exclusive outward rotation of the CH₂OR group. heating the substituted 3-formylcyclobutenes 324 and 327 resulted in exclusive inward rotation of the formyl group. Thermally induced resulted in the predominant outward rotation of the CO₂Et group. hand, the keto ester 315 showed no preference for the direction CO₂Et group during the thermal ring [See Thesis for Diagrams].

description: We address the issues of clustering and non-global logarithms for jet shapes in the process of production of a Higgs/vector boson associated with a single hard jet at hadron colliders. We perform an analytical fixed-order calculation up to second order in the coupling as well as an all-orders estimation for the specific invariant mass distribution of the highest-$p_t$ jet, for various jet algorithms. Our results are derived in the eikonal (soft) limit and are valid up to next-to-leading logarithmic accuracy. We perform a matching of the resummed distribution to next-to-leading order results from MCFM and compare our findings with the outputs of the Monte Carlo event generators Pythia 8 and Herwig 7. After accounting for non-perturbative effects we compare our results with available experimental data from the CMS collaboration for the Z + jet production. We find good agreement over a wide range of the observable.

description: We report the detection of a massive neutral gas outflow in the z=2.09 gravitationally lensed Dusty Star-Forming Galaxy HATLASJ085358.9+015537 (G09v1.40), seen in absorption with the OH+(1_1-1_0) transition using spatially resolved (0.5"x0.4") Atacama Large Millimeter/submillimeter Array (ALMA) observations. The blueshifted OH+ line is observed simultaneously with the CO(9-8) emission line and underlying dust continuum. These data are complemented by high angular resolution (0.17"x0.13") ALMA observations of CH+(1-0) and underlying dust continuum, and Keck 2.2 micron imaging tracing the stellar emission. The neutral outflow, dust, dense molecular gas and stars all show spatial offsets from each other. The total atomic gas mass of the observed outflow is 6.7x10^9 M_sun, >25% as massive as the gas mass of the galaxy. We find that a conical outflow geometry best describes the OH+ kinematics and morphology and derive deprojected outflow properties as functions of possible inclination (0.38 deg-64 deg). The neutral gas mass outflow rate is between 83-25400 M_sun/yr, exceeding the star formation rate (788+/-300 M_sun/yr) if the inclination is >3.6 deg (mass-loading factor = 0.3-4.7). Kinetic energy and momentum fluxes span 4.4-290x10^9 L_sun and 0.1-3.7x10^37 dyne, respectively (energy-loading factor = 0.013-16), indicating that the feedback mechanisms required to drive the outflow depend on the inclination assumed. We derive a gas depletion time between 29 and 1 Myr, but find that the neutral outflow is likely to remain bound to the galaxy, unless the inclination is small, and may be re-accreted if additional feedback processes do not occur.

description: Ebert et al. [Phys. Rev. Lett. 77, 3827 (1996)] have fractured icosahedral Al-Mn-Pd single crystals in ultrahigh vacuum and have investigated the cleavage planes in-situ by scanning tunneling microscopy (STM). Globular patterns in the STM-images were interpreted as clusters of atoms. These are significant structural units of quasicrystals. The experiments of Ebert et al. imply that they are also stable physical entities, a property controversially discussed currently. For a clarification we performed the first large scale fracture simulations on three-dimensional complex binary systems. We studied the propagation of mode I cracks in an icosahedral model quasicrystal by molecular dynamics techniques at low temperature. In particular we examined how the shape of the cleavage plane is influenced by the clusters inherent in the model and how it depends on the plane structure. Brittle fracture with no indication of dislocation activity is observed. The crack surfaces are rough on the scale of the clusters, but exhibit constant average heights for orientations perpendicular to high symmetry axes. From detailed analyses of the fractured samples we conclude that both, the plane structure and the clusters, strongly influence dynamic fracture in quasicrystals and that the clusters therefore have to be regarded as physical entities.

description: We generate the perturbative expansion of the single-particle Green's function and related self-energy for a half-filled single-band Hubbard model on a square lattice. We invoke algorithmic Matsubara integration to evaluate single-particle quantities for real and Matsubara frequencies and verify results through comparison to existing data on the Matsubara axis. With low order expansions at weak-coupling we observe a number of outcomes expected at higher orders: the opening of a gap, pseudogap behavior, and Fermi-surface reconstruction. Based on low-order perturbations we consider the phase diagram that arises from truncated expansions of the self-energy and Green's function and their relation via the Dyson equation. From Matsubara axis data we observe insulating behavior in direct expansions of the Green's function, while the same order of truncation of the self-energy produces metallic behavior. This observation is supported by additional calculations for real frequencies. We attribute this difference to the order in which diagrams are implicitly summed in the Dyson series. By separating the reducible and irreducible contributions at each order we show that the reducible diagrams implicitly summed in the Dyson equation lead to incorrect physics in the half-filled Hubbard model. Our observations for this particular case lead us to question the utility of the Dyson equation for any problem that shows a disparity between reducible and irreducible contributions to the expansion of the Green's function.

We also discuss the many-body singlet-triplet spin dynamics arising from coherent coupling between nearest neighbor double wells and derive an effective description for such system. We use it to study the generation of complex magnetic states by adiabatic and non-equilibrium dynamics.

description: Counterfactuals have become a popular technique nowadays for interacting with black-box machine learning models and understanding how to change a particular instance to obtain a desired outcome from the model. However, most existing approaches assume instant materialization of these changes, ignoring that they may require effort and a specific order of application. Recently, methods have been proposed that also consider the order in which actions are applied, leading to the so-called sequential counterfactual generation problem. In this work, we propose a model-agnostic method for sequential counterfactual generation. We formulate the task as a multi-objective optimization problem and present a genetic algorithm approach to find optimal sequences of actions leading to the counterfactuals. Our cost model considers not only the direct effect of an action, but also its consequences. Experimental results show that compared to state-of-the-art, our approach generates less costly solutions, is more efficient and provides the user with a diverse set of solutions to choose from.

description: The article examines the forced labour of prisoners of the Karlag labour camp in Karaganda/ Kazachstan over the time period from 1929 to 1960. On the basis of new archival material from the archive of the Karlag camp new light is shed on the forced labour of prisoners in the coal mines, which belonged to the camp. Most evident is the growing economic significance of forced labour: while at the beginning the punishment and reeducation of the prisoners who worked under extremely hard conditions in the coal mines stood in the foreground later on, in connection with an increasing demand for coal the economic aspects of forced labour became more and more important. The growing interest of the state in the coal production of the prisoners also led to a general improvement of their working and living conditions and health care.

description: Ever since the first observation of Bose-Einstein condensation in the nineties, ultracold quantum gases have been the subject of intense research, providing a unique tool to understand the behavior of matter governed by the laws of quantum mechanics. Ultracold bosonic atoms loaded in an optical lattice are usually described by the Bose-Hubbard model or a variant of it. In addition to the common insulating and superfluid phases, other phases (like density waves and supersolids) may show up in the presence of a short-range interparticle repulsion and also depending on the geometry of the lattice. We herein explore this possibility, using the graph of a convex polyhedron as "lattice" and playing with the coordination of nodes to promote the wanted finite-size ordering. To accomplish the job we employ the method of decoupling approximation, whose efficacy is tested in one case against exact diagonalization. We report zero-temperature results for two Catalan solids, the tetrakis hexahedron and the pentakis dodecahedron, for which a thorough ground-state analysis reveals the existence of insulating "phases" with polyhedral order and a widely extended supersolid region. The key to this outcome is the unbalance in coordination between inequivalent nodes of the graph. The predicted phases can be probed in systems of ultracold atoms using programmable holographic optical tweezers.

description: Finsler and Lagrange spaces can be equivalently represented as almost Kahler manifolds enabled with a metric compatible canonical distinguished connection structure generalizing the Levi Civita connection. The goal of this paper is to perform a natural Fedosov-type deformation quantization of such geometries. All constructions are canonically derived for regular Lagrangians and/or fundamental Finsler functions on tangent bundles.

Bauern und Städter, Deutsche und Slowenen – ein Brief aus dem Herzogtum Krain des Jahres 1869

description: The contribution focusses on a hand-written letter, which the German director of a factory near Ljubljana/Laibach sent to his brother, who lived near Göttingen. The author of the letter led the paper factory Vevče in Zalog/Salloch, which at that time was Austrian property (from 1870: Leykam-Josefsthal AG). Since 1990, this enterprise has been owned by the Austrian W. Hamburger AG. The letter dates from 1 June, 1869, and its author, from a partial perspective tending to supporting the German side, describes in detail the bitter skirmish between nationally minded Slovenes and members of German gymnastic associations. However, he takes the party of the factory workers, seeing them as a group detached from national „excesses“. The events related by the factory owner are contextualised by means of daily press reports. On the whole, the contribution provides a significant “snapshot” of Slovene social history during the times of national emancipation (1848–1880), which took place in the midst of the campaigns for a “United Slovenia” with its frequent mass gatherings (tabori), after the Austro-Hungarian “Ausgleich” (1867).

description: We report $^{121/123}$Sb nuclear quadrupole resonance (NQR) and $^{51}$V nuclear magnetic resonance (NMR) measurements on kagome metal CsV$_3$Sb$_5$ with $T_{\rm c}=2.5$ K. Both $^{51}$V NMR spectra and $^{121/123}$Sb NQR spectra split after a charge density wave (CDW) transition, which demonstrates a commensurate CDW state. The coexistence of the high temperature phase and the CDW phase between $91$ K and $94$ K manifests that it is a first order phase transition. At low temperature, electric-field-gradient fluctuations diminish and magnetic fluctuations become dominant. Superconductivity emerges in the charge order state. Knight shift decreases and $1/T_{1}T$ shows a Hebel--Slichter coherence peak just below $T_{\rm c}$, indicating that CsV$_3$Sb$_5$ is an s-wave superconductor.
Synthesis, characterization, and properties of some molybdenum diene complexes and related compounds

description: Reduction of [C’Mo(NO)I₂]₂ (Cp’ = η ⁵-C₅H₅ (Cp) or η ⁵-C₅Me₅ (Cp*)) by sodium amalgam in THF at -20°C in the presence of acyclic, conjugated dienes affords novel Cp'Mo(NO)( η⁴-s-trans-diene) complexes in isolated yields of -10 - 60%. When the diene is 2,3-dimethylbutadiene, CpMo(NO)( η⁴-cw-2,3-dimethylbutadiene) product complexes are also isolable in addition to the trans-diene isomers. However, these cis-diene compounds are the kinetic products and convert in solutions irreversibly to the isomeric trans-diene complexes. A preliminary kinetic study of this isomerization indicates that the isomerization is first order. Reactivity studies of the η⁴-trans-diene complexes show that they react reluctantly with Lewis bases such as carbon monoxide and phosphines to form the η²-diene complexes, CpMo(NO)(L)( η²-diene) (L = CO, PMePh₂, PMe₃). The η⁴-trans-diene complexes react with alkynes and acetone in ligand coupling reactions to form products in which the diene ligands have coupled with the unsaturated organic molecules. Three of these complexes have been structurally characterized using X-ray crystallography, those being CpMo(NO)[ σ,η³-endo-C(Me)₂-CH-CH-C(Me)₂C(Me)C(Ph)], CpMo(NO)[ σ,η³-exo-C(Me)₂-CH-CH-C(Me)₂C(Me)₂O], and Cp*Mo(NO)[σ,η³-endo-CH₂-CH-CH-CH₂C(Me)₂O]. These complexes and some of their analogues have also been characterized extensively using ¹H and ¹³C NMR spectroscopy. The product of the reaction between CpMo(NO)( η⁴-trans-2,5-dimethyI-2,4-hexadiene) and acetone, CpMo(NO)[σ,η³-exo-C(Me)₂-CH-CH-C(Me)₂C(Me)₂O], reacts further with acetone to form the trimer, [CpMo(NO)]₃ (μ₂: η²-: η¹-OMe₂)₃ which has also been characterized by X-ray crystallography. In a preliminary study of the reactivity of the η⁴-trans-diene complexes with electrophiles, it has been found that they react with protonic acids (HX: X = I, O₃SC₆H₄CH₃,O₂CCF₃) to form CpMo(NO)(η³-allyl)X complexes in which the proton has added to the diene ligand and the anion of the acid has coordinated to the metal center. The diiodo dimers [CpM(NO)I₂]₂ (M = Mo, W) react with 10 equivalents of PMe₃ to produce the new electron-rich nitrosyl complexes M(NO)I(PMe₃)₄, the other product being [(C₅H₅)PMe₃]I. It has been shown that the formation of the tetrakis(phosphine) complexes proceeds sequentially via the isolable intermediate species (η ⁵-C₅H₅)M(NO)I₂ (PMe₃) and [(η ⁵-C₅H₅)M(NO)I(PMe₃)₂]I. Treatment ofthe diiodo dimers with 4 equivalents of PMe₃ in the presence of sodium amalgam affords excellent yields of the related complexes (η ⁵-C₅H₅)M(NO)(PMe₃)₂.

description: We propose a natural Fedosov type quantization of generalized Lagrange models and gravity theories with metrics lifted on tangent bundle, or extended to higher dimension, following some stated geometric/ physical conditions (for instance, nonholonomic and/or conformal transforms to some physically important metrics or mapping into a gauge model). Such generalized Lagrange transforms define canonical nonlinear connection, metric and linear connection structures and model almost Kahler geometries with induced canonical symplectic structure and compatible affine connection. The constructions are possible due to a synthesis of the nonlinear connection formalism developed in Finsler and Lagrange geometries and deformation quantization methods.

description: Since the late 1970s, Slovene social science has been developing an increasing interest in gender studies. It was mostly political groups of feminist women who initiated the academic interest in topics related to women, acting in various Yugoslav contexts, but most of all in Belgrade, Zagreb, and Ljubljana. The increased sensitivity towards gender issues did not yet reach the historiographic field. Only at the end of the 1980s and the beginning of the 1990s, with already numerous initiatives within the humanities and social sciences under way, some changes occured also in historiography. The first studies dedicated to the history of women were promoted by historians like Darja Mihelič, Sabina Žnideršič, Neda Pagon, and Peter Vodopivec. As a matter of fact, it still were mainly the sociologists, political scientists, and philosophers who more consistently investigated the history of women, proposing it as a subject for university courses and promulgating important editorial initiatives. During the last decade, however, quicker and more profound changes occured. First of all, the number of young female academics interested in social, economic, and cultural history and in the presence and agency of women in the various historical periods increased. But also the general historiographic context has opened itself towards an increased attention to women’s, and subsequently gender, history.

description: Using particle system methodologies we study the propagation of financial distress in a network of firms facing credit risk. We investigate the phenomenon of a credit crisis and quantify the losses that a bank may suffer in a large credit portfolio. Applying a large deviation principle we compute the limiting distributions of the system and determine the time evolution of the credit quality indicators of the firms, deriving moreover the dynamics of a global financial health indicator. We finally describe a suitable version of the "Central Limit Theorem" useful to study large portfolio losses. Simulation results are provided as well as applications to portfolio loss distribution analysis.
