description: Sound propagation encompasses various acoustic phenomena including reverberation. Current virtual acoustic methods, ranging from parametric filters to physically-accurate solvers, can simulate reverberation with varying degrees of fidelity. We investigate the effects of reverberant sounds generated using different propagation algorithms on acoustic distance perception, i.e., how faraway humans perceive a sound source. In particular, we evaluate two classes of methods for real-time sound propagation in dynamic scenes based on parametric filters and ray tracing. Our study shows that the more accurate method shows less distance compression as compared to the approximate, filter-based method. This suggests that accurate reverberation in VR results in a better reproduction of acoustic distances. We also quantify the levels of distance compression introduced by different propagation methods in a virtual environment.

description: In this paper fundamental Wigner coefficients are determined algebraically by considering the eigenvalues of certain generalized Casimir invariants. Here this method is applied in the context of both type 1 and type 2 unitary representations of the Lie superalgebra gl(mjn). Extensions to the non-unitary case are investigated. A symmetry relation between two classes of Wigner coefficients is given in terms of a ratio of dimensions.

description: We use the "generalized hierarchical equation of motion" proposed in Paper I to study decoherence in a system coupled to a spin bath. The present methodology allows a systematic incorporation of higher order anharmonic effects of the bath in dynamical calculations. We investigate the leading order corrections to the linear response approximations for spin bath models. Two types of spin-based environments are considered: (1) a bath of spins discretized from a continuous spectral density and (2) a bath of physical spins such as nuclear or electron spins. The main difference resides with how the bath frequency and the system-bath coupling parameters are chosen to represent an environment. When discretized from a continuous spectral density, the system-bath coupling typically scales as $\sim 1/\sqrt{N_B}$ where $N_B$ is the number of bath spins. This scaling suppresses the non-Gaussian characteristics of the spin bath and justify the linear response approximations in the thermodynamic limit. For the physical spin bath models, system-bath couplings are directly deduced from spin-spin interactions with no reason to obey the $1/\sqrt{N_B}$ scaling. It is not always possible to justify the linear response approximations. Furthermore, if the spin-spin Hamiltonian and/or the bath parameters are highly symmetrical, these additional constraints generate non-Markovian and persistent dynamics that is beyond the linear response treatments.

description: Our goal is to compare two unequivalent definitions of the Gell-Mann channels. It turns out that both definitions coincide for qubits and qutrits. In higher dimensions, there exist some constraints under which the channels describe the same dynamics. Finally, we find the GKSL time-local generators for a class of the Gell-Mann channels.

description: Breakfast consumption can entail nutritional advantages positively affecting food choices. This study investigated the effect of minor changes in breakfast composition on the perceived attributes of foods, both at breakfast and at lunchtime. Four breakfasts were defined considering nutritional and perceptual factors. Three breakfasts varied just for a single cereal-based chocolate-containing food item, while a control breakfast mimicked fasting conditions. Breakfast perception was assessed before and after consumption. Subjects rated breakfast energy content on the basis of single items, while judged breakfast healthiness as a whole, suggesting that the combination of different ingredients can modify the perceived health value of foods. Additionally, 4 h after breakfast, a perceptual evaluation of lunch-related food images was performed, without differences among breakfasts. This study extends current knowledge on the relationship between subjective perceptual attributes and objective energy value and food composition, as well as on breakfast impact on food perception at lunchtime.

description: Atomic data are an important source of systematic uncertainty in our determinations of nebular chemical abundances. However, we do not have good estimates of these uncertainties since it is very difficult to assess the accuracy of the atomic data involved in the calculations. We explore here the size of these uncertainties by using 52 different sets of transition probabilities and collision strengths, and all their possible combinations, to calculate the physical conditions and the total abundances of O, N, S, Ne, Cl, and Ar for a sample of planetary nebulae and H II regions. We find that atomic data variations introduce differences in the derived abundance ratios as low as 0.1$-$0.2 dex at low density, but that reach or surpass 0.6$-$0.8 dex at densities above 10$^{4}$ cm$^{-3}$ in several abundance ratios, like O/H and N/O. Removing from the 52 datasets the four datasets that introduce the largest differences, the total uncertainties are reduced, but high density objects still reach uncertainty factors of four for their values of O/H and N/O. We identify the atomic data that introduce most of the uncertainty, which involves the ions used to determine density, namely, the transition probabilities of the S$^{+}$, O$^{+}$, Cl$^{++}$, and Ar$^{+3}$ density diagnostic lines, and the collision strengths of Ar$^{+3}$. Improved calculations of these data will be needed in order to derive more reliable values of chemical abundances in high density nebulae. In the meantime, our results can be used to estimate the uncertainties introduced by atomic data in nebular abundance determinations.

Adaptive Quantum Optimized Centroid Initialization

description: One of the major benefits of quantum computing is the potential to resolve complex computational problems faster than can be done by classical methods. There are many prototype-based clustering methods in use today, and selection of the starting nodes for the center points is often done randomly. For prototype-based clustering algorithms, this could lead to much slower convergence times. One of the causes of this may be prototype-based clustering accepting a local minima as a valid solution when there are possibly better solutions. Quantum computing, specifically quantum annealing, offers a solution to these problems by mapping the initial centroid problem to an Ising Hamiltonian where over time the lowest energy in the spectrum correlates to a valid, but better solution. A first approach to this problem utilizing quantum annealing was known as Quantum Optimized Centroid Initialization (QOCI), but this approach has some limitations both in results and performance. We will present a modification of QOCI known as Adaptive Quantum Optimized Centroid Initialization (AQOCI) which addresses many of the limitations in QOCI. The results presented are comparable to those obtained using classical techniques as well as being superior to those results found using QOCI.

description: Local conformational changes and global unfolding pathways of wildtype xyn11A recombinant and its mutated structures were studied through a series of atomistic molecular dynamics (MD) simulations, along with enzyme activity assays at three incubation temperatures to investigate the effects of mutations at three different sites to the thermostability. The first mutation was to replace an unstable negatively charged residue at a surface beta turn near the active site (D32G) by a hydrophobic residue. The second mutation was to create a disulphide bond (S100C/N147C) establishing a strong connection between an alpha helix and a distal beta hairpin associated with the thermally sensitive Thumb loop, and the third mutation add an extra hydrogen bond (A155S) to the same alpha helix. From the MD simulations performed, MM/PBSA energy calculations of the unfolding energy were in a good agreement with the enzyme activities measured from the experiment, as all mutated structures demonstrated the improved thermostability, especially the S100C/N147C proved to be the most stable mutant both by the simulations and the experiment. Local conformational analysis at the catalytic sites and the xylan access region also suggested that mutated xyn11A structures could accommodate xylan binding. However, the analysis of global unfolding pathways showed that structural disruptions at the beta sheet regions near the N-terminal were still imminent. These findings could provide the insight on the molecular mechanisms underlying the enhanced thermostability due to mutagenesis and changes in the protein unfolding pathways for further protein engineering of the GH11 family xylanase enzymes.

Ganz einfach: Es bedeutet vermutlich, dass ich als ‚Frau‘ in dieser Gesellschaft lebe.

Diesen multiplen Missstand bringt Franziska Schutzbach in ihrem Buch Die Erschöpfung der Frauen als These auf den Punkt. Es geht ihr dabei nicht um die individuelle Erschöpfung von Frauen, sondern darum, „dass die Erschöpfung Kern eines destruktiven ökonomischen Systems ist, das Sorge und Beziehungen zur ausbeutbaren Ressource degradiert hat“ (S. 270). Damit schließt das Buch auch an die Debatte um Care-Ökonomie an (vgl. bspw. Winker 2015, 2021).

description: Although squaring integers is deterministic, squares modulo a prime, $p$, appear to be random. First, because they are all generated by the multiplicative linear congruential equation, $x_{i+1} = g^2 x_i \mod p$, where $x_0 = 1$ and $g$ is any primitive root of $p$, a pseudorandom number heuristic suggests that they are, in fact, unpredictable. Moreover, one type of cryptography makes use of discrete algorithms, which depends on the difficulty of solving $a = g^n$ for $n$ given $a$ and $g$. This suggests that the squares, which are exactly the even powers of $g$, are hard to identify. On the other hand, the Legendre symbol, $(a/p)$, which equals $1$ if a is a square modulo $p$ and $-1$ otherwise, has proven patterns. For example, $(ab/p) = (a/p)(b/p)$ holds true, and this shows that squares modulo $p$ have some structure. This paper considers the randomness of the following sequence: $(1/p), (2/p), ..., ((p-1)/p)$. Because it consists of binary data, the runs test is applied, which suggests that the number of runs is exactly (p-1)/2. This turns out to be a theorem proved by Aladov in 1896 that is not widely known. Consequently, this is an example of a number theory fact that is revealed naturally in a statistical setting, but one that has rarely been noted by mathematicians.

description: This paper presents a novel mass-conservative mixed multiscale method for solving flow equations in heterogeneous porous media. The media properties (the permeability) contain multiple scales and high contrast. The proposed method solves the flow equation in a mixed formulation on a coarse grid by constructing multiscale basis functions. The resulting velocity field is mass conservative on the fine grid. Our main goal is to obtain first-order convergence in terms of the mesh size which is independent of local contrast. This is achieved, first, by constructing some auxiliary spaces, which contain global information that can not be localized, in general. This is built on our previous work on the Generalized Multiscale Finite Element Method (GMsFEM). In the auxiliary space, multiscale basis functions corresponding to small (contrast-dependent) eigenvalues are selected. These basis functions represent the high-conductivity channels (which connect the boundaries of a coarse block). Next, we solve local problems to construct multiscale basis functions for the velocity field. These local problems are formulated in the oversampled domain taking into account some constraints with respect to auxiliary spaces. The latter allows fast spatial decay of local solutions and, thus, allows taking smaller oversampled regions. The number of basis functions depends on small eigenvalues of the local spectral problems. Moreover, multiscale pressure basis functions are needed in constructing the velocity space. Our multiscale spaces have a minimal dimension, which is needed to avoid contrast-dependence in the convergence. The method's convergence requires an oversampling of several layers. We present an analysis of our approach. Our numerical results confirm that the convergence rate is first order with respect to the mesh size and independent of the contrast.

description: We consider the problem of optimally utilizing $N$ resources, each in an unknown binary state. The state of each resource can be inferred from state-dependent noisy measurements. Depending on its state, utilizing a resource results in either a reward or a penalty per unit time. The objective is a sequential strategy governing the decision of sensing and exploitation at each time to maximize the expected utility (i.e., total reward minus total penalty and sensing cost) over a finite horizon $L$. We formulate the problem as a Partially Observable Markov Decision Process (POMDP) and show that the optimal strategy is based on two time-varying thresholds for each resource and an optimal selection rule for which resource to sense. Since a full characterization of the optimal strategy is generally intractable, we develop a low-complexity policy that is shown by simulations to offer near optimal performance. This problem finds applications in opportunistic spectrum access, marketing strategies and other sequential resource allocation problems.

description: The construction of large-scale quantum networks relies on the development of practical quantum repeaters. Many approaches have been proposed with the goal of outperforming the direct transmission of photons, but most of them are inefficient or difficult to implement with current technology. Here, we present a protocol that uses a semi-hierarchical structure to improve the entanglement distribution rate while reducing the requirement of memory time to a range of tens of milliseconds. This protocol can be implemented with a fixed distance of elementary links and fixed requirements on quantum memories, which are independent of the total distance. This configuration is especially suitable for scalable applications in large-scale quantum networks.

description: The NDHA model comprehensively describes nitrous oxide (N2O) producing pathways by both autotrophic ammonium oxidizing and heterotrophic bacteria. The model was calibrated via a set of targeted extant respirometric assays using enriched nitrifying biomass from a lab-scale reactor. Biomass response to ammonium, hydroxylamine, nitrite and N2O additions under aerobic and anaerobic conditions were tracked with continuous measurement of dissolved oxygen (DO) and N2O. The sequential addition of substrate pulses allowed the isolation of oxygen-consuming processes. The parameters to be estimated were determined by the information content of the datasets using identifiability analysis. Dynamic DO profiles were used to calibrate five parameters corresponding to endogenous, nitrite oxidation and ammonium oxidation processes. The subsequent N2O calibration was not significantly affected by the uncertainty propagated from the DO calibration because of the high accuracy of the estimates. Five parameters describing the individual contribution of three biological N2O pathways were estimated accurately (variance/mean < 10% for all estimated parameters). The NDHA model response was evaluated with statistical metrics (F-test, autocorrelation function). The 95% confidence intervals of DO and N2O predictions based on the uncertainty obtained during calibration are studied for the first time. The measured data fall within the 95% confidence interval of the predictions, indicating a good model description. Overall, accurate parameter estimation and identifiability analysis of ammonium removal significantly decreases the uncertainty propagated to N2O production, which is expected to benefit N2O model discrimination studies and reliable full scale applications.

description: The coherent control of spin qubits forms the basis of many applications in quantum information processing and nanoscale sensing, imaging and spectroscopy. Such control is conventionally achieved by direct driving of the qubit transition with a resonant global field, typically at microwave frequencies. Here we introduce an approach that relies on the resonant driving of nearby environment spins, whose localised magnetic field in turn drives the qubit when the environmental spin Rabi frequency matches the qubit resonance. This concept of environmentally mediated resonance (EMR) is explored experimentally using a qubit based on a single nitrogen-vacancy (NV) centre in diamond, with nearby electronic spins serving as the environmental mediators. We demonstrate EMR driven coherent control of the NV spin-state, including the observation of Rabi oscillations, free induction decay, and spin-echo. This technique also provides a way to probe the nanoscale environment of spin qubits, which we illustrate by acquisition of electron spin resonance spectra of single NV centres in various settings.

description: In maize hybrid development, it is essential to know the parent’s performance per se in different environments as well as the genetic base in populations in order to facilitate selection of superior lines. The objective of this work was to estimate the genetic variance and heritability while assessing agronomic behavior in 237 maize fodder lines featuring different inbred levels and origin in two different locations. Traits such as plant height, cob height, stem diameter, and fodder yield were taken. A combined variance analysis was carried out using this information. The variable mean squares showing significant differences were used to estimate the genetic variance components. Significant differences were observed (p ≤ 0.01) for the line variation source and location × line interaction in all assessed characteristics. The genetic parameter estimation provided information on the existing genetic variance and heritability among the population which is important for the progress of the selection process. Lines CLWN701, CLWN345, CML476, CML216, CLWQ232, and CML 528 measured 74.8, 72.2, 67.7, 65.8, 63.8 and 62.5 t ha-1 , respectively showed the highest yield potential for green fodder.

description: Продление срока хранения молочной продукции является одной из самых значимых задач как для производителей молока, так и для его переработчиков. Наиболее перспективным методом решения этой проблемы представляется подавление развития патогенных микроорганизмов. Требования к безопасности молока и молочных продуктов предусматривают запрет на прямое внесение консервирующих веществ в молоко, однако оставляют возможность их применения в упаковочных материалах при условии безопасности самой упаковки. Целью нашего исследования явилось выявление воздействия консервирующих препаратов, в том числе в составе полиэтиленовой упаковки, на физико-химические и микробиологические свойства молока при разных температурах хранения. Внесение консервантов в молоко значительно подавило рост молочной микрофлоры при всех исследованных параметрах хранения. Установлено, что включение консерванта в упаковочную пленку не оказало существенного влияния на основные физико-химические показатели молока, при этом по прошествии 24 часов содержание молочнокислых бактерий в молоке составило 8,1х106 КОЕ/см3 при хранении в стеклянной упаковке, в то время как в упаковке с модифицированной пленкой их количество составило 1,4х106 КОЕ/см3.

description: We have carried out a detailed study of scaling region using detrended fractal analysis test by applying different forcing likewise noise, sinusoidal, square on the floating potential fluctuations acquired under different pressures in a DC glow discharge plasma. The transition in the dynamics is observed through recurrence plot techniques which is an efficient method to observe the critical regime transitions in dynamics. The complexity of the nonlinear fluctuation has been revealed with the help of recurrence quantification analysis which is a suitable tool for investigating recurrence, an ubiquitous feature providing a deep insight into the dynamics of real dynamical system. An informal test for stationarity which checks for the compatibility of nonlinear approximations to the dynamics made in different segments in a time series has been proposed. In case of sinusoidal, noise, square forcing applied on fluctuation acquired at P=0.12mbar only one dominant scaling region is observed whereas the forcing applied on fluctuation (P=0.004mbar) two prominent scaling regions have been explored reliably using different forcing amplitudes indicating the signature of crossover phenomena. Furthermore a persistence long range behaviour has been observed in one of these scaling regions. A comprehensive study of the quantifi- cation of scaling exponents has been carried out with the increase in amplitude and frequency of sinusoidal, square type of forcings. The scalings exponent is envisaged to be the roughness of the time series. The method provides a single quantitative idea of the scaling exponent to quantify the correlation properties of a signal.

Исследована влагоудерживающая способность сгустков мягких сыров из смеси молочного сырья в различных соотношениях. Результаты свидетельствуют о том, что увеличение количества коровьего молока в смеси приводит к повышению влагоудерживающей способности молочных сгустков. О преобразовании коллоидной системы молока в процессе формирования сгустка судили по изменению дисперсности белковых частиц, величину которой характеризовали количеством адсорбированного красителя. Выявлено, что с повышением доли козьего молока в смеси, возрастало количество красителя, адсорбированного полученным сгустком. При этом снижалось предельное напряжение сдвига, а продукт имел пластичную, размазывающуюся консистенцию.

description: Building on previous work, we have expanded our catalog of evolutionary models for stars with variable composition; here we present models for stars of mass 0.5 - 1.2 Msol, at scaled metallicities of 0.1 - 1.5 Zsol, and specific C/Fe, Mg/Fe, and Ne/Fe values of 0.58 - 1.72 C/Fe_sol, 0.54 - 1.84 Mg/Fe_sol and 0.5 - 2.0 Ne/Fe_sol, respectively. We include a spread in abundance values for carbon and magnesium based on observations of their variability in nearby stars; we choose an arbitrary spread in neon abundance values commensurate with the range seen in other low Z elements due to the difficult nature of obtaining precise measurements of neon abundances in stars. As indicated by the results of Truitt et al. (2015), it is essential that we understand how differences in individual elemental abundances, and not just the total scaled metallicity, can measurably impact a star's evolutionary lifetime and other physical characteristics. In that work we found that oxygen abundances significantly impacted the stellar evolution; carbon, magnesium, and neon are potentially important elements to individually consider due to their relatively high (but also variable) abundances in stars. We present 528 new stellar main sequence models, and we calculate the time-dependent evolution of the associated habitable zone boundaries for each based on mass, temperature, and luminosity. We also reintroduce the 2 Gyr "Continuously Habitable Zone" as a useful tool to help gauge the habitability potential for a given planetary system.

description: The NA62 experiment at CERN SPS is aimed to measure the branching ratio of the ultra-rare decay $K^+\rightarrowπ^+ ν\barν$ with 10\% accuracy. The experiment operates with a 75 GeV/c high intensity (750 MHz) secondary beam. A new detector, named Charged Particle Hodoscope (CHOD), designed to produce an input signal to the L0 trigger processor for events with charged particles produced in kaon decays, has been assembled, installed, integrated in NA62 Data Acquisition System (DAQ) and commissioned in 2016. During the whole 2016 run the detector has been in continuous operation. Design and performance features of the detector are presented.

description: The one-dimensional symmetric exclusion process, the simplest interacting particle process, is a lattice-gas made of particles that hop symmetrically on a discrete line respecting hard-core exclusion. The system is prepared on the infinite lattice with a step initial profile with average densities $ρ_{+}$ and $ρ_{-}$ on the right and on the left of the origin. When $ρ_{+} = ρ_{-}$, the gas is at equilibrium and undergoes stationary fluctuations. When these densities are unequal, the gas is out of equilibrium and will remain so forever. A tracer, or a tagged particle, is initially located at the boundary between the two domains; its position $X_t$ is a random observable in time, that carries information on the non-equilibrium dynamics of the whole system. We derive an exact formula for the cumulant generating function and the large deviation function of $X_t$, in the long time limit, and deduce the full statistical properties of the tracer's position. The equilibrium fluctuations of the tracer's position, when the density is uniform, are obtained as an important special case.

description: Do fuel cell electric vehicles have a future? This is one of the most controversial questions when it comes to future mobility. Looking at the current fleet of fuel cellelectric cars at just over 40,000 vehicles worldwide, many an automaker has also begun to tune in to the fuel cell's swan song. The aim of this master thesis is to show in which areas the fuel cell has potential, but also where its limits lie. With the help of the GREET® model, the carbon dioxide saving potentials compared to internal combustion engine vehicles are calculated along the entire vehicle operation pathway (well-to-wheel). Furthermore, the focus is on the economic efficiency of green hydrogen and of fuel cell electric vehicles themselves. The latter is to be presented on the basis of the total cost of ownership approach in a comparison with internal combustion engines and battery electric vehicles. The results of such a comparison show that the competitiveness of a fuel cell electric vehicle increases the larger the vehicle or the higher the annual mileage. For smaller vehicles and lower annual mileage, a battery electric vehicle has a clear competitive edge over fuel cell electric cars. With regard to the avoidance of carbondioxide emissions, the results of this master thesis show that the contribution of fuel cell electric vehicles in the Austrian transport sector remains very manageablein a "base scenario" with less than 2% of avoided carbon dioxide emissions in 2050.In a “decarbonisation scenario” with strong growth rates of fuel cell electric vehicles in the commercial vehicle segments, the picture is completely different.Here, up to almost a quarter of the current transport-related carbon dioxide emissions could be saved in 2050, but as a result electricity demand could alsoincrease by almost 35% compared to today, thus necessitating an even greater expansion of renewable energy capacities.
From physical linear systems to discrete-time series. A guide for analysis of the sampled experimental data

description: Modelling physical data with linear discrete time series, namely Fractionally Integrated Autoregressive Moving Average (ARFIMA), is a technique which achieved attention in recent years. However, these models are used mainly as a statistical tool only, with weak emphasis on physical background of the model. The main reason for this lack of attention is that ARFIMA model describes discrete-time measurements, whereas physical models are formulated using continuous-time parameter. In order to remove this discrepancy we show that time series of this type can be regarded as sampled trajectories of the coordinates governed by system of linear stochastic differential equations with constant coefficients. The observed correspondence provides formulas linking ARFIMA parameters and the coefficients of the underlying physical stochastic system, thus providing a bridge between continuous-time linear dynamical systems and ARFIMA models.

description: Steady growth of prevalence of the food allergy which reached epidemic level forces scientists to be engaged from around the world in studying of questions of pathogenesis, clinic, diagnostics, treatment and prevention of food allergy. However still a number of questions remains open. Much attention is paid to studying of the factors which are authentically influencing development of food allergy which knowledge would allow to carry out effective and reasonable prevention to influence formation of food tolerance. Still there are difficulties in diagnosis of food allergy. New methods of laboratory and tool diagnostics, including application of peptide microchips are actively studied. A set of works are devoted to questions of efficiency and safety allergen a specific immunotherapy of food allergy, including with use of recombinant food allergens. New opportunities of treatment of food allergy by means of special diets with the use of thermally processed foodstuff are studied. Problems of insufficient use of adrenaline for treatment of life-threatening manifestations of food allergy are covered. The difficulties connected with marking of foodstuff remain.
