0268 The Millennial Monument in Budapest as a Bearer of Memory, National Identity and Self-Awareness
Creators: name: Papp, Gábor György
Publisher: name: RIHA Journal
Year: 2021

description: In the 19th century, one of the most important national events in Hungary was the 1896 millennial celebration of the Hungarian conquest of the Carpathian Basin. A central act of the festivity’s symbolical episodes was the erection of the so-called Millennium Memorial (or Millennial Monument) at Heroes’ Square in Budapest. The monument consists of a colonnaded architectural framework that embraces a sculpture gallery featuring Hungarian leaders and rulers. My paper presents the history of the monument from concept to completion. Besides the artistic patterns of the architectural framework designed by Albert Schickedanz, special attention is given to the sculptures of the Hungarian sculptors who worked under the direction of the artist György Zala, as well as to the relations between the sculptors and the artistic scene of Vienna, and to the models they used. In addition to these primarily art historical aspects, my paper discusses the cultural context of the Memorial. It seeks answers to the questions of how the Memorial became a symbol of national identity already at the stage of planning and what ideas about the shaping of the national self-image defined the final form of the Memorial.

0267 Public Sculpture in Zagreb in the Second Half of the 19th Century
Creators: name: Kraševac, Irena
Publisher: name: RIHA Journal
Year: 2021

description: The Zagreb Green Horseshoe, or Zelena potkova in Croatian, is an original urban evocation of the Ringstraße in Vienna that represents an effort to create a characteristic urban space during the era of Historicism. This distinctive 19th century urban project provided an appropriate setting for monuments and sculptural decoration. Squares, parks and main streets thus became a stage where contemporaries encountered monuments to personalities whose memory was to be preserved. The evocation of historical figures as a part of the collective memory is one of the fundamental ideas behind erecting monuments in any public place. Zagreb, as a national metropolis, favoured monuments dedicated to persons who recalled the nation’s glorious past and to highly regarded individuals, artists and poets. This paper focuses on thirteen monuments that were erected from 1866 to 1914 in this model part of the city and discusses issues related to the clients, the artists and the individuals to whom they were dedicated. The monuments that extend along the Zelena potkova can match the monuments on the Ringstraße, both examples are part of a common heritage from the reign of Franz Joseph I of Austria.

0266 The Habsburgs and Public Monuments in 19th-Century Croatia
Creators: name: Damjanović, Dragan
Publisher: name: RIHA Journal
Year: 2021

description: This paper focuses on the analysis of the ways in which the cult of the Habsburg dynasty was promoted through public monuments in Croatia in the so-called Long 19th Century, from the end of the 18th to the early 20th century. Public sculpture in Croatia at this time was under a strong dominance of the national discourse – it mostly commemorated heroes of the Croatian cultural and sometimes also political history. Compared to the monuments to national heroes, the public monuments dedicated to members of the Habsburg family were smaller in number, and most often more modest in design and size. They can be divided into two basic groups – monuments commemorating events (Ereignisdenkmäler) from Croatian history connected with the Habsburgs, and monuments dedicated directly to individual members of the Habsburg family. The latter type of monuments is defined in this article in terms of what they commemorate and is divided into three groups: 1) monuments commemorating the role of the Habsburg emperors in the implementation of infrastructure projects, 2) monuments commemorating important anniversaries in the lives of individual members of the ruling house, and 3) monuments commemorating visits of Habsburgs to Croatia.

description: It has been shown that F, G, and early K dwarf hosts of Neptune-sized planets are not preferentially metal-rich. However, it is less clear whether the same holds for late K and M dwarf planet hosts. We report metallicities of Kepler targets and candidate transiting planet hosts with effective temperatures below 4500 K. We use new metallicity calibrations to determine [Fe/H] from visible and near-infrared spectra. We find that the metallicity distribution of late K and M dwarfs monitored by Kepler is consistent with that of the solar neighborhood. Further, we show that hosts of Earth- to Neptune-sized planets have metallicities consistent with those lacking detected planets and rule out a previously claimed 0.2 dex offset between the two distributions at 6sigma confidence. We also demonstrate that the metallicities of late K and M dwarfs hosting multiple detected planets are consistent with those lacking detected planets. Our results indicate that multiple terrestrial and Neptune-sized planets can form around late K and M dwarfs with metallicities as low as 0.25 of the solar value. The presence of Neptune-sized planets orbiting such low-metallicity M dwarfs suggests that accreting planets collect most or all of the solids from the disk and that the potential cores of giant planets can readily form around M dwarfs. The paucity of giant planets around M dwarfs compared to solar-type stars must be due to relatively rapid disk evaporation or a slower rate of core accretion, rather than insufficient solids to form a core.

0265 Czech Sculpture in the Late 19th and Early 20th Centuries and Its Attitude Towards Vienna
Creators: name: Krummholz, Martin
Publisher: name: RIHA Journal
Year: 2021

description: During the course of the 19th century, Czech society underwent an intensive process of national revival and emancipation from Vienna. This, of course, was also projected onto the field of visual arts: For a long time, under the influence of Czech nationalists, surveys of developments in the arts field did not include German-speaking artists from the Czech lands, such as the brothers Max and Franz Metzner or Hugo Lederer. Contacts between both individuals and institutions and Vienna thus became extremely complicated, and after 1900 they were generally considered undesirable by Czech nationalists. In 1902, the Mánes Fine Arts Association, which can take much of the credit for promoting modern art in the Czech milieu at that time, organized an exhibition in Prague of the works of Auguste Rodin, whose artistic style fundamentally influenced Czech sculpture in the first decade of the 20th century and disrupted the monopoly enjoyed until then by Josef Václav Myslbek. In contrast to Myslbek’s conventional equestrian monument to St Wenceslas, two other national monuments in Prague, the statues of Jan Hus (by Ladislav Šaloun) and of František Palacký (by Stanislav Sucharda) reflect the fascination with Rodinesque pathos at that time. The politically motivated suppression of contacts between the Czech milieu and Vienna and German-speaking countries on the one hand, and the support for intensive communication with Paris on the other, contributed to the progressive tendencies in Czech art before the First World War and to its exceptional plurality of styles.

Positron scattering and annihilation in hydrogen-like ions

description: Diagrammatic many-body theory is used to calculate the scattering phase shifts, normalized annihilation rates $Z_{\rm eff}$ and annihilation gamma spectra for positron collisions with the hydrogen-like ions He$^+$, Li$^{2+}$, B$^{4+}$ and F$^{8+}$. Short-range electron-positron correlations and longer-range positron-ion correlations are accounted for by evaluating nonlocal corrections to the annihilation vertex and the exact positron self-energy. The numerical calculation of the many-body theory diagrams is performed using B-spline basis sets. To elucidate the rôle of the positron-ion repulsion, the annihilation rate is also estimated analytically in the Coulomb-Born approximation. It is found that the energy dependence and magnitude of $Z_{\rm eff}$ is governed by the Gamow factor that characterizes the suppression of the positron wave function near the ion. For all of the H-like ions, the correlation enhancement of the annihilation rate is found to be predominantly due to corrections to the annihilation vertex, while the corrections to the positron wave function play only a minor rôle. Results of the calculations for $s$, $p$ and d-wave incident positrons of energies up to the positronium formation threshold are presented. Where comparison is possible, our values are in excellent agreement with the results obtained using other, e.g., variational, methods. The annihilation vertex enhancement factors obtained in the present calculations are found to scale approximately as $1+(1.6+0.46\ell)/Z_i$, where $Z_i$ is the net charge of the ion and $\ell$ is the positron orbital angular momentum. Our results for positron annihilation in H-like ions provide insights into the problem of positron annihilation with core electrons in atoms and condensed matter systems, which have similar binding energies.

0264 The Arts Policy of the Habsburg Empire in the Long 19th Century – "for the Good of Internal Peace within the Empire"
Creators: name: Gottsmann, Andreas
Publisher: name: RIHA Journal
Year: 2021

description: The ꞋLong 19th CenturyꞋ saw the development of modern arts policy in many European countries and also in the Habsburg monarchy. Although the creation of national codes was not yet completed at that time, the measures adopted for the promotion of the arts did play an important role in the cultural development of Central Europe at the turn of the century. In fact, the efforts of various generations of politicians and administrators aiming at creating some sort of cultural identification patterns, which were oriented to the common State, left their mark in the collective memory. Most notably, a remarkable effort was made to give broader parts of the population access to the arts. Hence, the promotion of the arts soon became one of the tasks of the modern "cultural State", whose effects were going to last beyond the end of the Monarchy. The basis for these common communication spaces was not to be found in a Habsburg-Austrian "Leitkultur" (core culture) focused on Vienna, but in the acceptance of the cultural diversity existing in this area.

description: Long-lived and high-fidelity memory for photonic polarization qubit (PPQ) is crucial for constructing quantum networks. Here we present an EIT-based millisecond storage system in which a moderate magnetic field is applied on a cold-atom cloud to lift Zeeman degeneracy. PPQ states are stored as two magnetic-field-insensitive spin waves. Especially, the influence of magnetic-field-sensitive spin waves on the storage performances is almost totally avoided. The measured average fidelities of polarization states are 98.6% at 200 us and 78.4% at 4.5 ms, respectively.

description: As neuroimaging databases grow in size and complexity, the time researchers spend investigating and managing the data increases to the expense of data analysis. As a result, investigators rely more and more heavily on scripting using high-level languages to automate data management and processing tasks. For this, a structured and programmatic access to the data store is necessary. Web services are a first step toward this goal. They however lack in functionality and ease of use because they provide only low level interfaces to databases. We introduce here PyXNAT, a Python module that interacts with The Extensible Neuroimaging Archive Toolkit (XNAT) through native Python calls across multiple operating systems. The choice of Python enables PyXNAT to expose the XNAT Web Services and unify their features with a higher level and more expressive language. PyXNAT provides XNAT users direct access to all the scientific packages in Python. Finally PyXNAT aims to be efficient and easy to use, both as a backend library to build XNAT clients and as an alternative frontend from the command line.

description: We study charmed and strange baryon resonances that are generated dynamically by a unitary baryon-meson coupled-channels model which incorporates heavy-quark spin symmetry. This is accomplished by extending the SU(3) Weinberg-Tomozawa chiral Lagrangian to SU(8) spin-flavor symmetry plus a suitable symmetry breaking. The model generates resonances with negative parity from the s-wave interaction of pseudoscalar and vector mesons with 1/2+ and 3/2+ baryons in all the isospin, spin, and strange sectors with one, two, and three charm units. Some of our results can be identified with experimental data from several facilities, such as the CLEO, Belle, or BaBar Collaborations, as well as with other theoretical models, whereas others do not have a straightforward identification and require the compilation of more data and also a refinement of the model.

description: Temporal metacognition (TMC) is defined as the ability to consciously self-regulate cognitive focus on the past, the present, and the future by utilizing metacognitive skills, emotions, knowledge, and experience. TMC stems conceptually from the idea of a balanced time perspective — the ability to switch between time horizons — and it builds upon the major theories of metacognition. We validated the German version of the Temporal Metacognition Scale (TMCS) translated from the Polish original with n = 226 native German speakers. Confirmatory Factor Analysis supported the three-factor model obtained in the original Polish version with the following subscales: Metacognitive Temporal Control, Cognitive Reconstruction of the Past, and Goal-Oriented Metatemporal Interconnectedness. All three scales yielded acceptable internal consistency. Their correlations with the subscales of the Zimbardo Time Perspective Inventory, Balanced Time Perspective Index, and other conceptually related psychological constructs, such as personality traits, well-being, experiencing emotions, and other features of metacognition, provide evidence for the validity of the German version of the TMCS.

description: A 3d symmetry protected topological phase, by definition must have symmetry protected nontrivial boundary states, namely its 2d boundary must be either gapless or degenerate. In this work we demonstrate that once we couple a 3d SPT phase to a lattice dynamical Z2 gauge field, in many cases the Z2 vison loop excitation (line defect) can be viewed as a "1d boundary" of the 3d SPT phase, and this line defect is guaranteed to have gapless or degenerate spectrum, which is also protected by the symmetry of the SPT phase.

Alternative separation of exchange and correlation energies in range-separated density-functional perturbation theory

description: An alternative separation of short-range exchange and correlation energies is used in the framework of second-order range-separated density-functional perturbation theory. This alternative separation was initially proposed by Toulouse et al. [Theor. Chem. Acc. 114, 305 (2005)] and relies on a long-range interacting wavefunction instead of the non-interacting Kohn-Sham one. When second-order corrections to the density are neglected, the energy expression reduces to a range-separated double-hybrid (RSDH) type of functional, RSDHf, where "f" stands for "full-range integrals" as the regular full-range interaction appears explicitly in the energy expression when expanded in perturbation theory. In contrast to usual RSDH functionals, RSDHf describes the coupling between long- and short-range correlations as an orbital-dependent contribution. Calculations on the first four noble-gas dimers show that this coupling has a significant effect on the potential energy curves in the equilibrium region, improving the accuracy of binding energies and equilibrium bond distances when second-order perturbation theory is appropriate.

description: The Vienna Art Academy has always attracted budding artists from all over the Empire, especially after the reform in 1872. Similarly, the School of Arts and Crafts in Vienna played an important role from its foundation in 1867. It served as a model for such institutions in the crown lands, including Zagreb, Budapest and Prague. At the same time, the project of the Vienna Ringstraße, in which many professors from the academy were involved, offered the prospect of commissions. Still, the networks of sculptors in the capital and the crown lands during these decades have not been widely explored. This is not a matter of purely art-historical questions; rather, the national question plays an important role. An international group of researchers is now tackling these connections, a century after the collapse of the Austro-Hungarian Empire and decades after the partial division of Europe by the Iron Curtain.

description: Using the recent formula presented by He and Cachazo-Mason-Skinner for the link representation of tree-level N=8 supergravity amplitudes, we derived a CSW-like expansion for the Next-to-MHV 6- and 7-graviton amplitudes by using the global residue theorem; a technique introduced originally for Yang-Mills amplitudes. We analytically checked the equivalence of one of the CSW terms and its corresponding Risager's diagram. For the remaining 6-graviton and all 7-graviton terms, we numerically checked the agreement with Risager's expansion. We showed that the conditions for the absence of contributions at infinity of the global residue theorem are satisfied for any number of particles. This means that our technique and Risager's should disagree starting at twelve particles where Risager's method is known to fail.

description: The supermassive black hole of M87 is one of the most massive black holes known and has been the subject of several stellar and gas-dynamical mass measurements; however the most recent revision to the stellar-dynamical black hole mass measurement is a factor of about two larger than the previous gas-dynamical determinations. Here, we apply comprehensive gas-dynamical models that include the propagation of emission-line profiles through the telescope and spectrograph optics to new Space Telescope Imaging Spectrograph observations from the Hubble Space Telescope. Unlike the previous gas-dynamical studies of M87, we map out the complete kinematic structure of the emission-line disk within about 40 pc from the nucleus, and find that a small amount of velocity dispersion internal to the gas disk is required to match the observed line widths. We examine a scenario in which the intrinsic velocity dispersion provides dynamical support to the disk, and determine that the inferred black hole mass increases by only 6%. Incorporating this effect into the error budget, we ultimately measure a mass of M_BH = (3.5^{+0.9}_{-0.7}) x 10^9 M_sun (68% confidence). Our gas-dynamical black hole mass continues to differ from the most recent stellar-dynamical mass by a factor of two, underscoring the need for carrying out more cross-checks between the two main black hole mass measurement methods.

description: Sequences that form DNA secondary structures, such as G-quadruplexes (G4s) and intercalated-Motifs (iMs), are abundant in the human genome and play various physiological roles. However, they can also interfere with replication and threaten genome stability. Multiple lines of evidence suggest G4s inhibit replication, but the underlying mechanism remains unclear. Moreover, evidence of how iMs affect the replisome is lacking. Here, we reconstitute replication of physiologically derived structure-forming sequences to find that a single G4 or iM arrest DNA replication. Direct single-molecule structure detection within solid-state nanopores reveals structures form as a consequence of replication. Combined genetic and biophysical characterisation establishes that structure stability and probability of structure formation are key determinants of replisome arrest. Mechanistically, replication arrest is caused by impaired synthesis, resulting in helicase-polymerase uncoupling. Significantly, iMs also induce breakage of nascent DNA. Finally, stalled forks are only rescued by a specialised helicase, Pif1, but not Rrm3, Sgs1, Chl1 or Hrq1. Altogether, we provide a mechanism for quadruplex structure formation and resolution during replication and highlight G4s and iMs as endogenous sources of replication stress.

description: In this contribution we will review our present understanding of the matter equation of state in the density and temperature conditions where it can be described by nucleonic degrees of freedom. At zero temperature, all the information is contained in the nuclear energy functional in its isoscalar and isovector channels. At finite temperature, particular emphasis will be given to the specificity of the thermodynamics in the nucleonic regime, with the simultaneous presence of long range electromagnetic and short range nuclear interactions. The astrophysical implications of the resulting phase diagram, as well as of different observables of exotic nuclei on the neutron-rich side, will be touched upon.

description: Let $k[X] = k[x_{i,j}: i = 1,..., m; j = 1,..., n]$ be the polynomial ring in $m n$ variables $x_{i,j}$ over a field $k$ of arbitrary characteristic. Denote by $I_2(X)$ the ideal generated by the $2 \times 2$ minors of the generic $m \times n$ matrix $[x_{i,j}]$. We give a closed formulation for the dimensions of the $k$-vector space $k[X]/(I_2(X) + (x_{1,1}^q,..., x_{m,n}^q))$ as $q$ varies over all positive integers, i.e., we give a closed form for the generalized Hilbert-Kunz function of the determinantal ring $k[X]/I_{2}[X]$. We also give a closed formulation of dimensions of related quotients of $k[X]/I_{2}[X]$. In the process we establish a formula for the numbers of some compositions (ordered partitions of integers), and we give a proof of a new binomial identity.

description: Inflationary models predict a correlation between primordial density perturbations (scalar metric perturbations) and gravitational waves (tensor metric perturbations) in the form of a scalar-scalar-tensor three-point correlation, or bispectrum in Fourier space. The squeezed limit of this bispectrum implies a quadrupolar asymmetry in the observed local power spectrum for matter and galaxies. Here we show (like others before) that an infrared divergence in the amplitude of this power asymmetry predicted in single-field slow-roll models is canceled by projection effects when considering the observed power spectrum. We then further evaluate the nonzero, but finite, residual quadrupolar power asymmetry that remains after the divergences are canceled. While the quadrupolar power asymmetry is small, it is conceptually important. Our calculation moreover clarifies how the predictions for this power asymmetry may change in models with different scalar-scalar-tensor bispectra, and shows that convincing detection of the quadrupolar power asymmetry would rule out the single-field slow-roll models of inflation.

In this thesis, we study the causal structure of Schwarzschild and Reissner–Nordström (RN) black holes in de Sitter (dS) and Anti-de Sitter (AdS) spacetimes. We find that the inner horizon of RN black holes is highly unstable and analyze how its conformal diagram evolves from the Schwarzschild conformal diagram. We illustrate the Penrose diagrams for uncharged and charged black holes within the constant curvature spacetimes and analyze their properties. We examine the smallest black holes in dS, finding their probability of nucleation, as well as the largest dS black holes, which lead to the Nariai solution. We demonstrate two methods for finding the Nariai geometry of RNdS, with the caveat that the inner horizon remains highly unstable. Finally, we find a parallel between gravitational and matrix methods, confirming that the underlying holographic description of dS relies on matrix quantum mechanics.

description: Sustainable development has  emerged as the defining human challenge of this century because of the sharp conflict between sustainability and current development practices. Among those conflicts, many populations are faced with severe water shortages, as well as  greenhouse effects due to combustion of fossil fuels. For the purpose of realizing the transition to sustainable development and societies, new technologies and policies must be developed and implemented. While new approaches and technologies span a large variety of methods and application areas, we will focus on the analysis and study of two specific technologies: reverse osmosis (RO) membrane systems for water purification and underground hydrogen storage.  In this thesis, we use a combination of mathematical modeling and numerical simulations to investigate, understand and predict the system response.  
In the first part of the thesis, we focus on RO membranes, an existing technology whose impact on access to potable water is expected to grow significantly in the near future. Fundamental knowledge of the physical processes governing flow and transport in RO systems is critical to guide their design and optimization for maximum performance under different operating conditions. In particular, we study the impact of turbulent flow on RO systems performance through the extension of the in-house solver SUMembraneFOAM to turbulent flows, and derive a new Reynolds-Sherwood correlation, routinely used to design system-scale modules, in turbulent conditions. A classical approach to quantify membrane performance, and its propensity to foul, is to estimate concentration polarization (CP) in proximity of the membrane surface. Currently, classical thin film theory is used to approximate CP under specific flow conditions.  We  derive an analytical and exact expression to calculate CP in RO systems and demonstrate its accuracy. In the second part of the thesis, we focus on a preliminary study of subsurface H2 storage. It is currently suggested that H2 subsurface storage does  not present additional challenges to those typically associated with CO2 storage. Here, we critically assess this hypothesis  by quantitatively investigating the potential (dis)similarities between the behavior of H2 underground and that of CO2. Our preliminary investigation warns that unique and additional modeling challenges may be expected in the context of  H2 underground storage, especially in reference to the  validity of multiphase Darcy’s law. This knowledge is critical to assess the feasibility to store hydrogen, guide the design, optimize site selection, and achieve the storage capacities that are necessary for the transition to a net-zero emission energy system.

description: We describe a technique coupling standard rheology and ultrasonic imaging with promising applications to characterization of soft materials under shear. Plane wave imaging using an ultrafast scanner allows to follow the local dynamics of fluids sheared between two concentric cylinders with frame rates as high as 10,000 images per second, while simultaneously monitoring the shear rate, shear stress, and viscosity as a function of time. The capacities of this "rheo-ultrasound" instrument are illustrated on two examples: (i) the classical case of the Taylor-Couette instability in a simple viscous fluid and (ii) the unstable shear-banded flow of a non-Newtonian wormlike micellar solution.

description: In the pursuit of highly active specialized metabolites from endemic plants, Centaurea papposa (Coss.) Greuter, an endemic plant in Algeria and Tunisia, was investigated and afforded eleven sesquiterpene lactones (1-11). Cytotoxic evaluation of these compounds using the in vitro MTT assay on three human cancerous cell lines (HeLa, SK-MEL-28 and HepG2), revealed that isolates 4, 8 and 9 (IC50 ≤ 10 μM) could be potential anti-cancer drugs for cervical cancer according to the National Cancer Institute. Further evaluation of the in vitro anti-inflammatory activity showed that compounds 1 and 4 inhibited the TNF-α induced ICAM-1 expression in HMEC-1 endothelial cells at a maximum of 21% and 2% of the control (IC50 values 21.9 and 5.7 μM, respectively). The Michael reactions of the α-methylene-γ-lactone ring seem to be responsible for the strong activity, while no toxicity was observed in the HMEC-1 cells in all the range of tested concentrations (6.25-50.0 µM).

description: In this note, we construct simple stochastic toy models for holographic gauge theories in which distributions of energy on a collection of sites evolve by a master equation with some specified transition rates. We build in only energy conservation, locality, and the standard thermodynamic requirement that all states with a given energy are equally likely in equilibrium. In these models, we investigate the qualitative behavior of the dynamics of the energy distributions for different choices of the density of states for the individual sites. For typical field theory densities of states (\log(ρ(E)) ~ E^{α<1}), the model gives diffusive behavior in which initially localized distributions of energy spread out relatively quickly. For large N gauge theories with gravitational duals, the density of states for a finite volume of field theory degrees of freedom typically includes a Hagedorn regime (\log(ρ(E)) ~ E). We find that this gives rise to a trapping of energy in subsets of degrees of freedom for parametrically long time scales before the energy leaks away. We speculate that this Hagedorn trapping may be part of a holographic explanation for long-lived gravitational bound states (black holes) in gravitational theories.

description: A new electrostatic storage ring for beams at energies up to 30keV.q is currently under development at the National Centre for Mathematics and Physics (NCMP), King Abdulaziz City for Science and Technology (KACST). The ring design is based on the existing electrostatic storage rings, but stretches significantly beyond them in that it shall form the core of a unique flexible experimental facility at KACST. The lattice of this ring has been designed in a way that enables the use of state-of-the-art experimental methods to study electron-ion, laser-ion, and ion-neutral beams interactions. The lattice design also allows for a future upgrade of the ring to a double storage ring structure that would enable ion-ion beam interactions to be performed. In this paper, we present the design of this ring with a focus on beam dynamics calculations for the 7o single-bend racetrack layout. The study is principally based on the SIMION8 program. We complemented this study further by using purpose-written routine and MAD-X simulation code. An in-depth investigation into beam stability under consideration of non-linear field components in the electrostatic optical elements, is presented. Finally, different working points and stability regions are discussed.

description: The present study aimed to experimentally identify the essential oil of Algerian Cyperus rotundus L. and to model the interaction of some known anti-inflammatory molecules with two key enzymes involved in inflammation, 5-Lypoxygenase (5-LO) and leukotriene A4 hydrolase (LTA4H). Gas chromatography/gas chromatography–mass spectrometry (GC/GC-MS) revealed that 92.7% of the essential oil contains 35 compounds, including oxygenated sesquiterpenes (44.2%), oxygenated monoterpenes (30.2%), monoterpene hydrocarbons (11.8%) and sesquiterpene hydrocarbons (6.5%). The major identified oxygenated terpenes are humulene oxide II, caryophyllene oxide, khusinol, agarospirol, spathulinol and trans-pinocarveol Myrtenol and α-terpineol are known to exhibit anti-inflammatory activities. Several complexes obtained after docking the natural terpenes with 5-LO and LTA4H have shown strong hydrogen bonding interactions. The best docking energies were found with α-terpineol, Myrtenol and khusinol. The interaction between the natural products and amino-acid residues HIS367, ILE673 and GLN363 appears to be critical for 5-LO inhibition, while the interaction with residues GLU271, HIS295, TYR383, TYR378, GLU318, GLU296 and ASP375 is critical for LTA4H inhibition. Molecular dynamics (MD) trajectories of the selected docked complexes showed stable backbone root mean square deviation (RMSD), supporting the stability of the natural product–enzyme interaction.

description: We study absorption of ultra high energy neutrinos by the cosmic neutrino background, with full inclusion of the effect of the thermal distribution of the background on the resonant annihilation channel. For a hierarchical neutrino mass spectrum (with at least one neutrino with mass below $\sim 10^{-2}$ eV), thermal effects are important for ultra high energy neutrino sources at $z \gtrsim 16$. The neutrino transmission probability shows no more than two separate suppression dips since the two lightest mass eigenstates contribute as a single species when thermal effects are included. Results are applied to a number of models of ultra high energy neutrino emission. Suppression effects are strong for sources that extend beyond $z \sim 10$, which can be realized for certain top down scenarios, such as superheavy dark matter decays, cosmic strings and cosmic necklaces. For these, a broad suppression valley should affect the neutrino spectrum at least in the energy interval $10^{12} - 10^{13}$ GeV -- which therefore is disfavored for ultra high energy neutrino searches -- with only a mild dependence on the neutrino mass spectrum and hierarchy. The observation of absorption effects would indicate a population of sources beyond $z \sim 10$, and favor top-down mechanisms; it would also be an interesting probe of the physics of the relic neutrino background in the unexplored redshift interval $z \sim 10 -100$.
