description: We derive an analytical connection between kinetic relaxation rate and bulk viscosity of a relativistic fluid in d spatial dimensions, all the way from the ultra-relativistic down to the near non-relativistic regime. Our derivation is based on both Chapman-Enskog asymptotic expansion and Grad's method of moments. We validate our theoretical results against a benchmark flow, providing further evidence of the correctness of the Chapman-Enskog approach; we define the range of validity of this approach and provide evidence of mounting departures at increasing Knudsen number. Finally, we present numerical simulations of transport processes in quark gluon plasmas, with special focus on the effects of bulk viscosity which might prove amenable to future experimental verification.

description: Die vorliegende Masterarbeit befasst sich mit der Autosuggestion als therapeutische Methode für sexologische Anliegen. Dafür wurde ihr Ursprung aufgearbeitet, mit ähnlichen (sexologischen) Ansätzen in Bezug gesetzt, und die Grenzen davon dargestellt. Anhand der Recherche wurde weiter eine 30-tägige autosuggestive Intervention zum Anliegen sexueller Lustlosigkeit bei neun Cis-Frauen in hetero- und homosexuellen Beziehungen durchgeführt. Das Erleben mit dem Anliegen vor, sowie auch nach der Intervention wurde mit zwei qualitativen, halbstandardisierten, schriftlichen Fragebogen nach Döring (2022) erörtert. Das Ziel der Studie war, unbewusste, negative Glaubenssätze in Bezug zu sexueller Lustlosigkeit in positive und/ oder realistische umzulenken, was bei einigen Probandinnen gut gelungen ist. Diejenigen, die von weniger Wirkung berichteten, konnten trotzdem von einer Bewusstmachung ausgewählter Themen in Bezug zur sexuellen Lustlosigkeit profitieren und klarere Ziele für sich definieren. Zum Schluss werden in der Arbeit Ansätze zur Weiterentwicklung dieser Methode für sexologische Anliegen anhand der Theorie reflektiert, gemischt mit Erkenntnissen aus der Studie.

description: Plant mediated synthesis of metal nanoparticles (MNPs) has been considered as a reliable green technique for mitigating the involvement of toxic chemicals and which is widely used for desired applications. In the present study, a simple and environment friendly approach for the synthesis of silver nanoparticles (AgNPs) using the aqueous extract of Cynodon dactylon was proposed. The phytochemicals present in C. dactylon acted as the reducing as well as the capping agents during the nanoparticle synthesis. The aqueous extract of C. dactylon added to AgNO3 solution showed a colour change from brown to black at room temperature which confirmed the formation of AgNPs. UV-Vis spectral analysis revealed the surface plasmon resonance band of synthesised AgNPs at around 380 nm, while FT-IR spectroscopy confirmed the role of biomolecules present in the plant extract in the reduction and efficient stabilisation of AgNPs. The X-ray diffraction (XRD) patterns confirmed distinctive peaks corresponding to the crystalline planes of cubic silver. Shape and surface morphology of green AgNPs were examined by SEM. Biosynthesized AgNPs were predominantly cubical and spherical with an average particle size of 30.5 nm approximately as observed through SEM and DLS analysis respectively. The EDS analysis displayed intense signals of silver element. The stability of AgNPs was confirmed by zeta potential analysis. A negative zeta potential value of −17.1 mV indicated the stability and good dispersion of AgNPs. Antimicrobial and anti-inflammatory potentials of green synthesised AgNPs were analysed through in vitro techniques. The cytotoxic effect of green AgNPs on normal fibroblast cells (L929) was studied to analyse its effect on normal cells.

description: Eiähnliche Gebilde aus Feuerstein- und Kreidefüllungen der Steckmuschel Pinna decussata Goldfuss, 1837 (Bivalvia: Ostreida) aus dem oberen Unter-Maastrichtium der Insel Rügen/Vorpommern werden beschrieben. Gegenüber der ersten vorläufigen Beschreibung durch Kutscher (1970) können diese früheren Deutungen dahingehend erweitert werden, dass es sich bei den „Eiern“, bzw. „Ei“-Pake-ten, um den Laich muschelbewohnender Krebse handeln könnte. Weitere Interpretationen werden diskutiert. Die durch Kříž& Soukup (1975) vertretene Meinung, dass es sich um Kalziumphosphat-Ooide handelt, kann ausgeschlossen werden. Die Untersuchung der Steinkern-Oberflächen der „eier“führenden Muscheln ergab bei 30 % von ihnen den Nachweis von Krebsresten. Sollte sich die vermutete Beziehung zwischen Pinna, den „Eiern“ und den derzeit unbestimmbaren Krebsresten bewahrheiten, wäre dies der erstmalige indirekte Nachweis für die Existenz muschelbewohnender Krebse (Pinnotheridae de Haan, 1833) in der Ober-Kreide Europas.
description: Kutscher M & Weinrich M: Egg packages in fossil Pinna decussata Goldfuss (Bivalvia) provide indirect evidence of Cretaceous mem-bers of the Pinnotheridae de Haan (Crustacea).Egg-like structures, occurring singly or clustered into packages, have been discovered from the flint or chalk infillings of fossil Pinna decussata Goldfuss, 1837 (Bivalvia: Ostreida) from upper Lower Maastrichtian chalk of the Isle of Ruegen, western Pomerania. The initial description of these structures by Kutscher (1970) is revised, and the hypothesis offered that the “eggs” and “egg” packages could repre-sent the spawn of clam-inhabiting crabs. The interpretation of the “eggs” as calciumphosphatic oolites (Kříž & Soukup 1975) is dismissed. Thorough screenings of the steinkern surfaces of the “egg”-bearing bivalves revealed that 30% of the specimens contained brachyuran remains. If in fact a relationship existed between Pinna, the “eggs” and the remains of decapod crustaceans, then the discovery would represent the first record of Late Cretaceous clam-inhabiting crabs (Pinnotheridae de Haan, 1833) from Europe.

description: The literature explaining social collapse mainly focuses on factors such as wars, climate change or disease, as exemplified by numerous examples of collapses which have occurred during the Late Bronze Age in the Near East and in the South-eastern Mediterranean region. This paper aims at demonstrating that collapse can also have economic reasons. Indeed, collapse may be the outcome of an economic growth process which is inherently unsustainable. More precisely, we claim that several ancient societies collapsed because the form of economic development which they relied on eventually proved to be unable to sustain their standard of living. It is believed that the Únĕtice societies – central European Early Bronze Age - were among those that collapsed for that reason. A simple model is presented to demonstrate that, in this agricultural economy, the introduction of bronze mining and metallurgy led to unsustainable development and its subsequent collapse.

description: In French-speaking Belgium, one of the new missions of the teacher will be to develop learners' information skills, namely their skills in searching, evaluating, and using information on the web. But do teachers know the strategies used by their students to adapt their teaching interventions? The aim of this study is to provide an overview of the different strategies used by 8 to 13 year old students when searching online. To achieve this objective, we use the IPS-I model and a methodology based on the analysis of the actual practices of 260 primary and secondary school students. Our results show that almost all of the students tested are novices in information retrieval. They do little or no research planning, use basic strategies, never check the reliability and relevance of the information they find and do not cite the sources used. These findings, in the light of previous empirical research on online search behaviour, allow for reflection on educational interventions and provide recommendations for educational practice.

description: We present a complete relativistic analysis for the scalar radiation emitted by a particle in circular orbit around a Schwarzschild-anti-de Sitter black hole. If the black hole is large, then the radiation is concentrated in narrow angles- high multipolar distribution- i.e., the radiation is synchrotronic. However, small black holes exhibit a totally different behavior: in the small black hole regime, the radiation is concentrated in low multipoles. There is a transition mass at $M=0.427 R$, where $R$ is the AdS radius. This behavior is new, it is not present in asymptotically flat spacetimes.

description: A new approach has been used to explain the experimental data for the $^{16}$O+$^{28}$Si system over a wide energy range in the laboratory system from 29.0 to 142.5 MeV. A number of serious problems has continued to plague the study of this system for a couple of decades. The explanation of anomalous large angle scattering data; the reproduction of the oscillatory structure near the Coulomb barrier; the out-of-phase problem between theoretical predictions and experimental data; the consistent description of angular distributions together with excitation functions data are just some of these problems. These are long standing problems that have persisted over the years and do represent a challenge calling for a consistent framework to resolve these difficulties within a unified approach. Traditional frameworks have failed to describe these phenomena within a single model and have so far only offered different approaches where these difficulties are investigated separately from one another. The present work offers a plausible framework where all these difficulties are investigated and answered. Not only it improves the simultaneous fits to the data of these diverse observables, achieving this within a unified approach over a wide energy range, but it departs for its coupling potential from the standard formulation. This new feature is shown to improve consistently the agreement with the experimental data and has made major improvement on all the previous coupled-channels calculations for this system.

description: Inverse energy cascade regime of two dimensional turbulence is investigated by means of high resolution numerical simulations. Numerical computations of conditional averages of transverse pressure gradient increments are found to be compatible with a recently proposed self-consistent Gaussian model. An analogous low order closure model for the longitudinal pressure gradient is proposed and its validity is numerically examined. In this case numerical evidence for the presence of higher order terms in the closure is found. The fundamental role of conditional statistics between longitudinal and transverse components is highlighted.

description: To establish systematic guidelines for accelerator decommissioning, a large-scale activation survey was conducted at representative synchrotron radiation facilities in Japan. The neutron flux during accelerator operation was measured with various dosimeters. A Monte Carlo simulation was conducted for some facilities to verify the special neutron distribution and their spectra. Beam loss points, reflected as high-dose-rate areas, were identified by a whole-beamline survey with a survey meter, and the generated radionuclides and their activity were determined with a lanthanum bromide (LaBr3) scintillation spectrometer. In all facilities, the activation level was quite low. Whole-beamline tunnels made of concrete were not activated, and no radionuclides were detected except for natural nuclides. In addition, almost all beamline components were either not or minimally activated. Although the acceleration energy is very high for radiation synchrotron facilities, the generation of radioactive waste would be very low.
A general-purpose timestep criterion for simulations with gravity

description: We describe a new adaptive timestep criterion for integrating gravitational motion, which uses the tidal tensor to estimate the local dynamical timescale and scales the timestep proportionally. This provides a better candidate for a truly general-purpose gravitational timestep criterion than the usual prescription derived from the gravitational acceleration, which does not respect the equivalence principle, breaks down when $\mathbf{a}=0$, and does not obey the same dimensional scaling as the true timescale of orbital motion. We implement the tidal timestep criterion in the simulation code GIZMO, and examine controlled tests of collisionless galaxy and star cluster models, as well as fully-dynamic galaxy merger and cosmological dark matter simulations. The tidal criterion estimates the dynamical time faithfully, and generally provides a more efficient timestepping scheme compared to an acceleration criterion. Specifically, the tidal criterion achieves order-of-magnitude smaller energy errors for the same number of force evaluations in potentials with inner profiles shallower than $ρ\propto r^{-1}$ (ie. where $\mathbf{a}\rightarrow 0$), such as star clusters and cored galaxies. For a given problem these advantages must be weighed against the additional overhead of computing the tidal tensor on-the-fly, but in many cases this overhead is small.

description: We rigorously derive an effective quantum mechanical Hamiltonian from N=4 gauge theory in the BMN limit. Its eigenvalues yield the exact one-loop anomalous dimensions of scalar two-impurity BMN operators for all genera. It is demonstrated that this reformulation vastly simplifies computations. E.g. the known anomalous dimension formula for genus one is reproduced through a one-line calculation. We also efficiently evaluate the genus two correction, finding a non-vanishing result. We comment on multi-trace two-impurity operators and we conjecture that our quantum-mechanical reformulation could be extended to higher quantum loops and more impurities.

Queueing Analysis of GPU-Based Inference Servers with Dynamic Batching: A Closed-Form Characterization

description: GPU-accelerated computing is a key technology to realize high-speed inference servers using deep neural networks (DNNs). An important characteristic of GPU-based inference is that the computational efficiency, in terms of the processing speed and energy consumption, drastically increases by processing multiple jobs together in a batch. In this paper, we formulate GPU-based inference servers as a batch service queueing model with batch-size dependent processing times. We first show that the energy efficiency of the server monotonically increases with the arrival rate of inference jobs, which suggests that it is energy-efficient to operate the inference server under a utilization level as high as possible within a latency requirement of inference jobs. We then derive a closed-form upper bound for the mean latency, which provides a simple characterization of the latency performance. Through simulation and numerical experiments, we show that the exact value of the mean latency is well approximated by this upper bound. We further compare this upper bound with the latency curve measured in real implementation of GPU-based inference servers and we show that the real performance curve is well explained by the derived simple formula.

description: This study aims to determine the chemical composition of essential oil (EO) extracted from the aerial parts of Schinus molle L., as well as its phytotoxicity on germination and seedling growth against some invasive weed species of cereal crops and wheat (Triticum durum, cultivar Chen’S). Gas chromatography/mass spectrometry (GC-MS) identified 51 components (representing 95.26% of the total EO composition). Shyobunone (10.14%), 1-phellandrene (9.63%), α-cadinol (7.46%), δ-cadinene (7.45%), and germacrene D (7.09%) were the most abundant compounds. The effect of EO on weed species germination, root and shoot growth was moderate to strong. When 0.02% and 0.03% of the oil were applied, EO had a strong phytotoxic effect, resulting in 100% failure of Bromus rigidus germination. In addition to determining the responsible compound, the observed phytotoxicity suggestedthat S. molle essential oil could be used as an environmentally friendly biopesticide.

description: The present paper deals with some structural properties of transportation cost spaces, also known as Arens-Eells spaces, Lipschitz-free spaces and Wasserstein spaces. The main results of this work are: (1) A necessary and sufficient condition on an infinite metric space $M$, under which the transportation cost space on $M$ contains an isometric copy of $\ell_1$. The obtained condition is applied to answer the open questions asked by Cúth and Johanis (2017) concerning several specific metric spaces. (2) The description of the transportation cost space of a weighted finite graph $G$ as the quotient $\ell_1(E(G))/Z(G)$, where $E(G)$ is the edge set and $Z(G)$ is the cycle space of $G$. This is a generalization of the previously known result to the case of any finite metric space.

description: We introduce a novel coupling potential for the scattering of deformed light heavy-ion reactions. This new approach is based on replacing the usual first-derivative coupling potential by a new, second derivative coupling potential in the coupled-channels formalism. The new approach has been successfully applied to the study of the $^{12}$C+$^{12}$C, $^{12}$C+$^{24}$Mg, $^{16}$O+$^{28}$Si and $^{16}$O+$^{24}$Mg systems and made major improvements over all the previous coupled-channels calculations for these systems. This paper also shows the limitations of the standard coupled-channels theory and presents a global solution to the problems faced in the previous theoretical accounts of these reactions.

description: Callicarpa nudiflora (C. nudiflora) is widely used in the treatment of bleeding related diseases. However, its main material basis has not been fully defined which limits the in-depth study of screening out the material basis of hemostasis and coagulation from C. nudiflor. In this study, the method of spectrum-effect relationship was used to quickly screen the material basis of hemostasis and coagulation. The five compounds related to hemostasis and coagulation were screened as Alyssonoside (P24), Luteolin (P25), Quercetin (P26), Apigenin (P28), Isorhamnetin (P29). And the contribution of these five peaks to hemostasis and coagulation efficacy was P24 > P25 > P28 > P26 > P29.

description: Controlling an evolving population is an important task in modern molecular genetics, including directed evolution for improving the activity of molecules and enzymes, in breeding experiments in animals and in plants, and in devising public health strategies to suppress evolving pathogens. An optimal intervention to direct evolution should be designed by considering its impact over an entire stochastic evolutionary trajectory that follows. As a result, a seemingly suboptimal intervention at a given time can be globally optimal as it can open opportunities for desirable actions in the future. Here, we propose a feedback control formalism to devise globally optimal artificial selection protocol to direct the evolution of molecular phenotypes. We show that artificial selection should be designed to counter evolutionary tradeoffs among multi-variate phenotypes to avoid undesirable outcomes in one phenotype by imposing selection on another. Control by artificial selection is challenged by our ability to predict molecular evolution. We develop an information theoretical framework and show that molecular time-scales for evolution under natural selection can inform how to monitor a population in order to acquire sufficient predictive information for an effective intervention with artificial selection. Our formalism opens a new avenue for devising artificial selection methods for directed evolution of molecular functions.

This condition is proved to be covariant with respect to the Darboux transformation of a general form. Nonlinear equations arising from the compatibility condition of the Lax pairs in the matrix case include, in particular, Nahm equations, Volterra, Bogoyavlenskii and Toda lattices.

description: Waste heat recovery is the most prominent development in businesses aiming to lower their carbon footprint. Instead of allowing the excess heat generated as a by-product to be lost into the atmosphere, businesses in any type of industry are starting the practice of recycling this heat and putting it to better use. Not only does it reduce their overall energy consumption, but it also curtails their contribution to global warming. Infraleuna GmbH, an exemplar in this endeavour, actively employs WHR technologies. However, heat always manages to escape in some form. In order to do its part in combatting global warming, Infraleuna GmbH is always trying to optimize its efficiency. This research delves into identifying heat loss sources within Infraleuna’s operations and devising a system to minimize them. The study proposes diverse models tailored to specific heat sources, accounting for available thermal potential and varying parameters. To facilitate calculations of enthalpies and construct pressure-enthalpy (p-H) diagrams, the Solkane 8.0.0 application will be employed. This investigation contributes valuable insights to the field of sustainable energy practices, emphasizing the critical role of WHR in combatting global warming. By bridging theory and practical implementation, we pave the way for more efficient industrial processes and a greener future.

description: Gravity on noncommutative analogues of compact spaces can give a finite mode truncation of ordinary commutative gravity. We obtain the actions for gravity on the noncommutative two-sphere and on the noncommutative ${\bf CP}^2$ in terms of finite dimensional $(N\times N)$-matrices.

description: We introduce spin Calogero-Moser systems associated with root systems of simple Lie algebras and give the associated Lax representations (with spectral parameter) and fundamental Poisson bracket relations. The associated integrable models (called integrable spin Calogero-Moser systems in the paper) and their Lax pairs are then obtained via Poisson reduction and gauge transformations. For Lie algebras of $A_{n}$-type, this new class of integrable systems includes the usual Calogero-Moser systems as subsystems. Our method is guided by a general framework which we develop here using dynamical Lie algebroids.

description: Lippia origanoides essential oil (LOEO) is extensively utilised as food preservative due to its antioxidant and antibacterial activities. In this study, the antioxidant and anti-ageing effects of LOEO was investigated in vivo using the nematode Caenorhabditis elegans. The gas chromatography-mass spectrometry analysis indicated that the main components of LOEO are carvacrol and thymol. LOEO treatment improved physiological parameters such as pharyngeal pumping, locomotion and body size indicating that is not toxic to C. elegans. LOEO treatment showed antioxidant effect in C. elegans by reducing endogenous ROS (Reactive Oxygen Species) production and increasing their survival under oxidative stress. Finally, LOEO treatment significantly extended C. elegans lifespan and alleviated the paralysis induced by β-amyloid peptide overexpression in the muscle. This work demonstrates for the first time LOEO antioxidant and anti-ageing properties on an organism level providing a valuable proof of principle to support further studies in the development of nutraceuticals or antioxidant phytotherapy.

description: This paper studies the controllability of networked relative coupling systems (NRCSs), in which subsystems are of fixed high-order linear dynamics and coupled through relative variables depending on their neighbors, from a structural perspective. The purpose is to explore conditions for subsystem dynamics and network topologies under which for almost all weights of the subsystem interaction links, the corresponding numerical NRCSs are controllable, which is called structurally controllable. Three types of subsystem interaction fashions are considered: 1) each subsystem is single-input-single-output (SISO), 2) each subsystem is multiple-input-multiple-output (MIMO), and the weights for all channels between two subsystems are identical, and 3) each subsystem is MIMO, but different channels between two subsystems can be weighted differently. {We show that all parameter-dependent modes of the NRCSs are generically controllable under some necessary connectivity conditions. We then derive necessary and/or sufficient conditions for structural controllability depending on subsystem dynamics and network topologies' connectivity in a decoupled form for all the three interaction fashions.} We also extend our results to handle certain subsystem heterogeneities and demonstrate their direct applications on some practical systems, including the mass-spring-damper system and the power network.

How Do Supernovae Impact the Circumgalactic Medium? I. Large-Scale Fountains Around a Milky Way-Like Galaxy

description: Feedback is indispensable in galaxy formation. However, lacking resolutions, cosmological simulations often use ad hoc feedback parameters. Conversely, small-box simulations, while better resolving the feedback, cannot capture gas evolution beyond the simulation domain. We aim to bridge the gap by implementing small-box results of supernovae-driven outflows into dark matter halo-scale simulations and studying their impact on large scales. Galactic outflows are multiphase, but small-box simulations show that the hot phase (T$\approx$ 10$^{6-7}$ K) carries the majority of energy and metals. We implement hot outflows in idealized simulations of the Milky Way halo, and examine how they impact the circumgalactic medium (CGM). In this paper, we discuss the case when the star formation surface density is low and therefore the emerging hot outflows are gravitationally bound by the halo. We find that outflows form a large-scale, metal-enriched atmosphere with fountain motions. As hot gas accumulates, the inner atmosphere becomes "saturated". Cool gas condenses, with a rate balancing the injection of the hot outflows. This balance leads to a universal density profile of the hot atmosphere, independent of mass outflow rate. The atmosphere has a radially-decreasing temperature, naturally producing the observed X-ray luminosity and column densities of O VI, O VII, O VIII. The self-regulated atmosphere has a baryon and a metal mass of $(0.5-1.2)\times 10^{10}M_\odot$ and $(0.6-1.4)\times 10^8 M_\odot$, respectively, small compared to the ``missing" baryons and metals from the halo. We conjecture that the missing materials reside at even larger radii, ejected by more powerful outflows in the past.
