description: This article surveys propaganda on the Ottoman home front during the Great War by focusing on the role of official and semi-official bodies, the means they used, and the ideological content to which they referred. Propaganda, mainly made by the Committee of Union and Progress, the ruling party in the Ottoman Empire during the Great War, addressed soldiers, young men who would be conscripted, as well as Muslim-Turkish women. During the first two years of the war, propaganda had the capacity to mobilize the targeted groups; however, from 1917, it began to lose its impact on Ottoman society due to worsening socio-economic conditions.

description: Portugal’s participation in the First World War, first in Africa and then on the European front, was marked by profound discord. In light of the crisis that swept across the nation in the wake of the war, which would culminate in an authoritarian regime, the young First Republic struggled to capitalize on the Allied victory. Within the context of a broader culture of war, we seek to analyze the construction of the official memory of this conflict. We analyze processes of remembrance, attempting to grasp their nature and whether they correspond to interpretations that see the violent experience of conflict as heralding a cultural rupture, one inherently associated with the brutalization of society and politics in the postwar period.

Hysteretic behaviour of steel- and fibre-reinforced elastomeric isolators fitted with superelastic shape memory alloy wire
Creators: name: Hedayati Dezfuli, Farshad
Publisher: name: University of British Columbia
Year: 2015

description: Among different types of earthquake protective mechanisms, elastomeric base isolators, also called rubber bearings (RBs), are one of the most well-known systems that are widely used in buildings and bridges. They can regulate the seismic response of structures, increase the public safety, and reduce the cost of repair and rehabilitation by providing lateral flexibility and dissipating the earthquake’s energy. RBs consist of elastomeric layers which are reinforced with steel shims or fibre-reinforced polymer composites. Seeking performance improvements, as well as cost and weight reduction led scientists to introduce different types of RBs. However, most RBs possess weaknesses such as limited shear strain capacity, un-recovered residual deformation, and instability due to large deformations. Using superelastic (ability to regain original shape upon unloading) shape memory alloy (SMA) in the form of wire, bar, or spring is a solution to partially overcome the aforementioned limitations. Its unique characteristics such as a flag-shaped hysteresis with zero residual deformation, superelastic effect (up to 13.5% recoverable strain) and a suitable fatigue property make it an ideal candidate for such applications. Objectives of this thesis are to propose a new generation SMA wire-based RBs (SMA-RB) and develop a novel constitutive model for such smart isolators in order to accurately capture their shear hysteretic behaviour. With the purpose of evaluating the performance of SMA-RBs in structural applications, the seismic fragility of a highway bridge isolated by SMA-RBs was assessed. First, a number of scaled carbon fibre-reinforced elastomeric isolators (C-FREIs) were manufactured and tested. Then, based on the experimental observations, numerical simulations were generated using finite element method (FEM). Results showed that incorporating SMA wires into natural and high-damping rubber bearings (NRB, HDRB) slightly improves the re-centring capability and energy dissipation capacity. However, equipping lead rubber bearing (LRB) with double cross SMA wires significantly reduces the residual deformation and noticeably enhances the energy damping property. It was also depicted that the developed hysteresis of SMA model can be characterized by three stiffnesses and two shear strain limits upon activation of SMA wires. Findings revealed that SMA wires can increase the reliability of elastomeric bearings and bridge system.

description: This study aimed to systematically analyze all cases of infective endocarditis (IE) by Klebsiella species in the literature. A systematic review of PubMed, Scopus and Cochrane library (through 27th January 2021) for studies providing epidemiological, clinical, microbiological as well as treatment data and outcomes of IE by Klebsiella species was performed. In this review, a total of 66 studies were included, providing data for 67 patients. A prosthetic valve was present in 16.4%, while the most common causative pathogen was K. pneumoniae followed by K. oxytoca. The aortic valve was the most commonly infected intracardiac site, followed by the mitral valve. The diagnosis was based on transthoracic echocardiography in 46.2%, while the diagnosis was set at autopsy in 9.2% of included patients. Blood cultures were positive in 93.8%. Fever and sepsis were the most frequent clinical presentations, followed by embolic phenomena, paravalvular abscess, and heart failure. Cephalosporins, aminoglycosides, and carbapenems were the most frequently used antimicrobials. Surgical treatment along with antimicrobials was performed in 37.3% of included patients. Clinical cure was noted in 80.3%, while the overall mortality was 19.4%. Infection at the aortic valve was independently associated with mortality by IE. This systematic review gives a comprehensive description of IE by Klebsiella and provides information on epidemiology, clinical manifestations, therapeutic strategies and their outcomes.
Impact of a Liquid Drop on a Granular Medium: inertia, viscosity and surface tension effects on the drop deformation

description: An experimental study of liquid drop impacts on a granular medium is proposed. Four fluids were used to vary physical properties: pure distilled water, water with glycerol at 2 concentrations 1:1 and 1:2 v/v and water with Tween 20 at the concentration of 0.1g/l. The drop free fall height was varied to obtain a Weber number (We) between 10 and 2000. Results showed that obtained crater morphologies highly depend on the impacting drop kinetic energy E_{K}. Different behaviours during the drop spreading, receding and absorption are highlighted as function of the fluids viscosity and surface tension. Experimental absorption times are also commented and compared with a simplified theoretical model. Drops maximal extensions and craters diameters were found to scale as $We^{1/5}$ and $E_K^{1/5}$ respectively. In both cases, found dependencies are smaller than those reported in literature: $We^{1/4}$ for drop impacts on solid or granular surfaces and $E_K^{1/4}$ for spherical solid impacts on granular media.

description: We study the damping of molecular vibrations due to electron-hole pair excitations in donor-acceptor(D-A) type molecular rectifiers. At finite voltage additional non-equilibrium electron-hole pair excitations involving both electrodes become possible, and contribute to the stimulated emission and absorption of phonons. We point out a generic mechanism for D-A molecules, where the stimulated emission can dominate beyond a certain voltage due to inverted position of the D and A quantum resonances. This leads to current-driven amplification (negative damping) of the phonons similar to laser-action. We investigate the effect in realistic molecular rectifier structures using first principles calculations.

A comparison of our results to recent H1 data suggests that the color octet mechanism is indeed realized in J/psi photoproduction, although the predictivity of our results still suffers from uncertainties in the color-octet long-distance matrix elements.

Electronic Structure Calculations with the Tran-Blaha Modified Becke-Johnson Density Functional

Year: 2010
Subjects: subject: Materials Science (cond-mat.mtrl-sci)
subject: FOS: Physical sciences

description: We report a series of calculations testing the predictions of the Tran-Blaha functional for the electronic structure and magnetic properties of condensed systems. We find a general improvement in the properties of semiconducting and insulating systems, relative to calculations with standard generalized gradient approximations, although this is not always by the same mechanism as other approaches such as the quasiparticle GW method. In ZnO the valence bands are narrowed and the band gap is increased to a value in much better agreement with experiment. The Zn $d$ states do not move to higher binding energy as they do in LDA+U calculations. The functional is effective for systems with hydride anions, where correcting self-interaction errors in the 1$s$ state is important. Similarly, it correctly opens semiconducting gaps in the alkaline earth hexaborides.It correctly stabilizes an antiferromagnetic insulating ground state for the undoped cuprate parent CaCuO$_2$, but seriously degrades the agreement with experiment for ferromagnetic Gd relative to the standard local spin density approximation and generalized gradient approximations. This is due to positioning of the minority spin $4f$ states at too low an energy. Conversly, the position of the La $4f$ conduction bands of La$_2$O$_3$ is in reasonable accord with experiment as it is with standard functionals. The functional narrows the Fe $d$ bands of the parent compound LaFeAsO of the iron high temperature superconductors, while maintaining the high Fe spectral weight near the Fermi energy.

description: The role of HeH+ has been newly assessed with the aid of newly calculated rates which use entirely ab initio methods, thereby allowing us to compute more accurately the relevant abundances within the global chemical network of the early universe. A comparison with the similar role of the ionic molecule LiH+ is also presented. Quantum calculations have been carried out for the gas-phase reaction of HeH+ with H atoms with our new in-house code, based on the negative imaginary potential method. Integral cross sections and reactive rate coefficients obtained under the general conditions of early universe chemistry are presented and discussed. With the new reaction rate, the abundance of HeH+ in the early universe is more than one order of magnitude larger than in previous studies. Our more accurate findings further buttress the possibility to detect cosmological signatures of HeH+.

description: Since its beginnings in 2001, MPI has shown more than ever a very high innovation potential. As expected, the number of publications is increasing and the interest in MPI is greater than ever. This certainly has to do with the growing number of commercial systems currently in operation. To this end, this editorial introduces topics in the current IJMPI Volume 7 No. 1 (2021) that reflect well the breadth of our field. More particular, these topics ranges from novel reconstruction techniques based on deep image priors, methods to improve spatial selectivity, tracer characterization, and new scanner geometries. These are four very exciting topics on MPI that are worth diving into.

description: We present an ESR study at excitation frequencies of 9.4 GHz and 222.4 GHz of powders and single crystals of a Prussian Blue analogue (PBA), RbMn[Fe(CN)6]*H2O in which Fe and Mn undergoes a charge transfer transition between 175 and 300 K. The ESR of PBA powders, also reported by Pregelj et al. (JMMM, 316, E680 (2007)) is assigned to cubic magnetic clusters of Mn2+ ions surrounding Fe(CN)6 vacancies. The clusters are well isolated from the bulk and are superparamagnetic below 50 K. In single crystals various defects with lower symmetry are also observed. Spin-lattice relaxation broadens the bulk ESR beyond observability. This strong spin relaxation is unexpected above the charge transfer transition and is attributed to a mixing of the Mn3+ - Fe2+ state into the prevalent Mn2+ - Fe3+ state.

description: We determine, by means of density functional theory, the stability and the structure of graphene nanoribbon (GNR) edges in presence of molecules such as oxygen, water, ammonia, and carbon dioxide. As in the case of hydrogen-terminated nanoribbons, we find that the most stable armchair and zigzag configurations are characterized by a non-metallic/non-magnetic nature, and are compatible with Clar's sextet rules, well known in organic chemistry. In particular, we predict that, at thermodynamic equilibrium, neutral GNRs in oxygen-rich atmosphere should preferentially be along the armchair direction, while water-saturated GNRs should present zigzag edges. Our results promise to be particularly useful to GNRs synthesis, since the most recent and advanced experimental routes are most effective in water and/or ammonia-containing solutions.

description: For nonlinear eigenvalue problems $T(lambda)x = 0$ satisfying a minmax characterization of its eigenvalues iterative projection methods combined with safeguarded iteration are suitable for computing all eigenvalues in a given interval. Such methods hit their limitation if a large number of eigenvalues (in the interior of the spectrum) are required. In this paper we propose a localized version of safeguarded iteration which is able to cope with this problem.
Escape from the potential well: competition between long jumps and long waiting times

description: Within a concept of the fractional diffusion equation and subordination, the paper examines the influence of a competition between long waiting times and long jumps on the escape from the potential well. Applying analytical arguments and numerical methods, we demonstrate that the presence of long waiting times distributed according to a power-law distribution with a diverging mean leads to very general asymptotic properties of the survival probability. The observed survival probability asymptotically decays like a power-law whose form is not affected by the value of the exponent characterizing the power-law jump length distribution. It is demonstrated that this behavior is typical of and generic for systems exhibiting long waiting times. We also show that the survival probability has a universal character not only asymptotically but also at small times. Finally, it is indicated which properties of the first passage time density are sensitive to the exact value of the exponent characterizing the jump length distribution.

Basierend auf theoretischen Ansätzen und empirischen Studien werden geeignete Einflussfaktoren identifiziert und deren kausale Zusammenhänge in Form von Hypothesen formuliert, die anschließend kausalanalytisch überprüft werden. Die empirischen Befunde belegen, dass insbesondere die Kooperationserfahrung und die Planungsintensität einen positiven Einfluss auf die Effizienz der Kooperation haben. Entgegen der allgemeinen Auffassung in der Kooperationsforschung konnte hingegen kein direkter positiver Zusammenhang zwischen der Intensität der Zusammenarbeit und der Effizienz gefunden werden. Die Befunde der Studie zeigen vielmehr, dass aufgrund der höheren organisatorischen Komplexität bei einer intensiven Zusammenarbeit gleichzeitig eine intensivere Planung vorhanden sein muss.
description: Because of the importance of inter-firm cooperation in research and development in the field of biotechnology, the authors analyze effects of relevant factors on the management of inter-organizational R&D-projects. Based on prior theoretical and empirical research, certain factors on the management of R&D-cooperation were identified and causal relationships between these factors were analyzed using structural equation modelling. Results of the empirical study in the biotechnology industry show that prior experience with the cooperation partner and the intensity of planning have a positive effect on the efficiency of the cooperation. In contrast to the literature, no direct positive effect of the intensity of cooperation on the efficiency was observed. We conclude that the organisational complexity depending on the intensity of cooperation require a high level of planning.
Utilizing graph classes for community detection in social and complex networks
Creators: name: Nastos, James
Publisher: name: University of British Columbia
Year: 2015

description: Social network analysis is a cross-disciplinary study of interest to mathematicians, physicists, computer scientists and sociologists. It deals with looking at large networks of interactions and extracting useful or meaningful information from them. One attribute of interest is that of identifying social communities within a network: how such a substructure should be defined is a widely-studied problem in itself. With each new definition, there is a need to study in what applications or context such a definition is appropriate, and develop algorithms and complexity results for the computation of these clusterings. This thesis studies problems related to graph clustering, motivated by the social networking problem of community detection. One main contribution of this thesis is a new definition of a specific kind of family-like community, accompanied by theoretical and computational justifications. Additional results in this thesis include proofs of hardness for the quasi-threshold editing problem and the diameter augmentation problem, as well as improved exact algorithms for cograph and quasi-threshold edge deletion and vertex deletion problems.

description: We present an analytical theory for the nonlinear optical response of a strongly interacting Rydberg gas under conditions of electromagnetically induced transparency. Simple formulae for the third order optical susceptibility are derived and shown to be in excellent agreement with recent experiments. The obtained expressions reveal strong nonlinearities, which in addition are of highly nonlocal character. This property together with enormous strength of the Rydberg-induced nonlinearities is shown to yield a unique laboratory platform for nonlinear wave phenomena, such as collapse-arrested modulational instabilities in a self-defocussing medium.

description: The use of the internet for business purposes and among consumers is spreading at an impressive rate. Companies use it for a lot of different activities like, for example, marketing, online shopping and customer service. However, the use of the internet for the purpose of innovation, to create ideas and concepts, is still underdeveloped. Practical experience shows that online communities are suitable for developing innovative ideas with users. To gain a deeper understanding of the underlying mechanisms we have taken a case-study approach. Based on this we generate a set of propositions concerning characteristics that a community should have in order to foster innovativeness. Our findings show that communities should be social, access should be restricted and it is necessary that users are free to post critical messages. Furthermore, the threads should be organised to create a lively discussion and users have to be able to build-up reputation.

description: We study the equation of state (EOS) of nuclear matter as function of density. We expand the energy per particle (E/A) of symmetric infinite nuclear matter in powers of the density to take into account 2,3,. . .,N-body forces. New EOS are proposed by fitting ground state properties of nuclear matter (binding energy, compressibility and pressure) and assuming that at high densities a second order phase transition to the Quark Gluon Plasma (QGP) occurs. The latter phase transition is due to symmetry breaking at high density from nuclear matter (locally color white) to the QGP (globally color white). In the simplest implementation of a second order phase transition we calculate the critical exponent ? by using Landau's theory of phase transition. We find ? = 3. Refining the properties of the EOS near the critical point gives ? = 5 in agreement with experimental results. We also discuss some scenarios for the EOS at finite temperatures.

description: We study the decomposition problem for tensor powers of $B_2$-fundamental modules. To solve this problem singular weight technique and injection fan algorithms are applied. Properties of multiplicity coefficients are formulated in terms of multiplicity functions. These functions are constructed showing explicitly the dependence of multiplicity coefficients on the highest weight coordinates and the tensor power parameter. It is thus possible to study general properties of multiplicity coefficients for powers of the fundamental $B_2$- modules.

description: The talk is composed of two parts, both set within the AdS/CFT context. In the first part, I discuss holographic insight into strongly coupled field theory in a black hole background. I conjecture two new gravitational solutions, dubbed black funnels and black droplets, which describe two distinct deconfined phases in the field theory at finite temperature. I also briefly mention puzzles associated with an analogous set-up in a rotating black hole background. In the second part of the talk, I discuss time-dependent states in a CFT on flat spacetime background, exemplified by the conformal soliton flow. Here I focus on puzzles regarding the nature of entropy in time-evolving states and its holographic dual.

description: In this paper we generalize the automated multi–level substructuring method to certain classes of nonlinear eigenvalue problems which can be partitioned into an essential linear and positive definite pencil and a small residual. The efficiency of the method is demonstrated by numerical examples modeling damped vibrations of a structure with nonproportional damping, a gyroscopic eigenproblem, and a rational eigenproblem governing free vibrations of a fluid–solid structure.

description: We develop a rigorous formalism for the description of the evolution of observables of quantum systems of particles in the mean-field scaling limit. The corresponding asymptotics of a solution of the initial-value problem of the dual quantum BBGKY hierarchy is constructed. Moreover, links of the evolution of marginal observables and the evolution of quantum states described in terms of a one-particle marginal density operator are established. Such approach gives the alternative description of the kinetic evolution of quantum many-particle systems to generally accepted approach on basis of kinetic equations.

description: This paper presents an overview and introduction to Smoothed Particle Hydrodynamics and Magnetohydrodynamics in theory and in practice. Firstly, we give a basic grounding in the fundamentals of SPH, showing how the equations of motion and energy can be self-consistently derived from the density estimate. We then show how to interpret these equations using the basic SPH interpolation formulae and highlight the subtle difference in approach between SPH and other particle methods. In doing so, we also critique several `urban myths' regarding SPH, in particular the idea that one can simply increase the `neighbour number' more slowly than the total number of particles in order to obtain convergence. We also discuss the origin of numerical instabilities such as the pairing and tensile instabilities. Finally, we give practical advice on how to resolve three of the main issues with SPMHD: removing the tensile instability, formulating dissipative terms for MHD shocks and enforcing the divergence constraint on the particles, and we give the current status of developments in this area. Accompanying the paper is the first public release of the NDSPMHD SPH code, a 1, 2 and 3 dimensional code designed as a testbed for SPH/SPMHD algorithms that can be used to test many of the ideas and used to run all of the numerical examples contained in the paper.

description: Appetitive conditioning processes are considered to play a key role in the etiology and maintenance of Gaming Disorder (GD). For GD patients, addiction-related stimuli (visual gaming stimuli) acquire strong personal meaning through repeated pairing with the positive emotions experienced during gaming. Conversely, addiction-unrelated rewards (e.g. monetary, sexual) become less important. This implies that addiction-related stimuli (vs. unrelated stimuli) should also produce greater conditioned responses in patients with GD when used as rewards in a conditioning paradigm. However, this hypothesis has not been examined to date. In the present study, we thus aim to investigate whether neural responses in appetitive conditioning differ between GD patients, risky gamers and healthy participants depending on the rewards used (addiction-related or unrelated). We will recruit 102 subjects in total (34 per group), who will participate in a classical appetitive conditioning paradigm in the MRI scanner. Conditioned stimuli will either be associated with a gaming reward (CS+gaming), a monetary reward (CS+money) or a sexual reward (CS+sexual) while a fourth stimulus (CS-) will never be paired with any reward. We will assess group differences in subjective ratings, skin conductance responses and neural reactivity in NAcc, caudate nucleus and amygdala to the conditioned stimuli. We expect greater conditioned responses to the CS+gaming and smaller responses to both CS+money and CS+sexual in GD patients and risky gamers compared to the healthy participants.
Structural basis for differential electron flux in human methionine synthase reductase and cytochrome P450 reductase

description: Human diflavin oxidoreductases, methionine synthase reductase (MSR) and cytochrome P450 reductase (CPR), share overall structural organization, substrate specificity, and direction of electron flow. However, MSR exhibits repressed catalytic activity and weak substrate binding compared to CPR. In this study, we identified structural features that control the differential kinetic properties of these flavoenzymes. Single point mutations in the MSR and CPR active sites were studied by steady state and pre-steady state absorbance spectrophotometric techniques to reveal structure-function relationships. In the research first chapter, we investigated the role of a conserved tryptophan in MSR that lies coplanar with the FAD cofactor. Reducing the side chain size resulted in a 1.5- and \textgreater400-fold tighter NADPH binding affinity in W697H and W697S and lowered the preference for NADPH over NADH. W697H also accelerated flavin reduction by 4.6-fold. Thus, the energetic cost of Trp697 displacement by the nicotinamide ring presents an energy barrier to NADPH binding. Consequently, Trp697 regulates coenzyme affinity, and coenzyme preference by ensuring initial recognition of the 2',5'-ADP moiety. The second research chapter evaluated the effect of more conservative mutations, W697Y and W697F, that resulted in improved coenzyme binding affinity and 9-fold accelerated flavin reduction. Equivalent mutations in CPR slowed flavin reduction. Thus, Trp697 gates hydride transfer in MSR, but not in CPR. Instead, following hydride transfer, electron flow in CPR is limited by displacement of the oxidized nicotinamide ring. This is supported by the 46-fold faster flavin reduction of the 2'-phosphate-binding site variant K602AV603K which weakened coenzyme affinity. In the third research chapter, we analyzed the role of FAD proximal His322 which is within hydrogen bonding distance to the catalytic triad residue Asp674 in CPR. The equivalent residue in MSR is Ala312. Through reciprocal mutagenesis, we found that H322A had stronger affinity for NADPH but slower flavin reduction, while A312H weakened coenzyme affinity. His322 is proposed to weaken coenzyme binding affinity by competing with the nicotinamide ring for electrostatic interaction with Asp674, thereby accelerating NADP+ release and electron flow through CPR. The final research chapter shifted to the conserved FAD-stacking tryptophan residue (Trp704) in plant CPR from Artemisia annua (AaCPR) for an additional perspective on overall CPR catalysis. The steady state and pre-steady state data revealed that Trp704 also triggers NADP+ release, however this step is not as critical for electron flux in AaCPR compared to human CPR.
Revealing the "missing" low-mass stars in the S254-S258 star forming region by deep X-ray imaging

description: (abbreviated) In the central part of the S254-S258 star forming complex, a dense embedded cluster of very young stellar objects (S255-IR) is sandwiched between the two HII regions S255 and S257. This interesting configuration had led to different speculations such as dynamical ejection of the B-stars from the central cluster or triggered star formation in a cloud that was swept up in the collision zone between the two expanding HII regions. The presence or absence of low-mass stars associated with these B-stars can discriminate between the possible scenarios. We performed a deep Chandra X-ray observation of the S254-S258 region in order to efficiently discriminate young stars from the numerous older field stars in the area. We detected 364 X-ray point sources, providing a complete sample of all young stars in the observed region down to ~0.5 Msun. A clustering analysis identifies three significant clusters, containing 64 X-ray sources in total. After accounting for X-ray background contaminants, this implies that about 250 X-ray sources constitute a widely scattered population of young stars. This number agrees well with the expectation for the low-mass population associated to the B-stars in S255 and S257 as predicted by an IMF extrapolation. These results are consistent with the scenario that these two B-stars represent an earlier stellar population and that their expanding HII regions have swept up the central cloud and trigger star formation therein.
