description: We provide an axiomatic framework for the study of smooth extensions of generalized cohomology theories. Our main results are about the uniqeness of smooth extensions, and the identification of the flat theory with the R/Z-theory. In particular, we show that there is a unique smooth extension of K-theory and of MU-cobordism with a unique multiplication, and that the flat theory in these cases is naturally isomorphic to the homotopy theorist's version of the cohomology theory with R/Z-coefficients. For this we only require a small set of natural compatibility conditions.

Subjects: SECS-P/06 Economia applicata

description: Food commodity prices fluctuations have important impacts on poverty and food insecurity across the world.
Conventional models have not provided a complete picture of recent price spikes in agricultural commodity markets,
while there is an urgent need for appropriate policy responses. Perhaps new approaches are needed in order to better
understand international spill-overs, the feedback between the real and the financial sectors and also the link between
food and energy prices. In this paper, we present results from a new worldwide dynamic model that provides short and
long-run impulse responses of wheat international prices to various real shocks.

description: This paper presents a multiwavelength investigation of the Galactic HII IRAS 17149$-$3916. Using the Giant Meterwave Radio Telescope, India, first low-frequency radio continuum observations at 610 and 1280 MHz for this region are presented. The ionized gas emission displays an interesting cometary morphology which is likely powered by the early type source, E4 (IRS-1). The origin of the cometary morphology is discussed under the framework of the widely accepted bow shock, champagne flow, and clumpy cloud mechanisms. The mid- and far-infrared data from Spitzer-GLIMPSE and Herschel-Hi-GAL reveal a complex network of pillars, clumps, bubble, filaments, and arcs suggesting the profound influence of massive stars on the surrounding medium. Triggered star formation at the tip of an observed pillar structure is reported. High-resolution ALMA continuum data show a string of cores detected within the identified clumps. The core masses are well explained by thermal Jeans fragmentation and support the hierarchical fragmentation scenario. Four `super-Jeans' cores are identified which, at the resolution of the present data set, are suitable candidates to form high-mass stars.

description: We consider the influence of a terahertz field on the breathing dynamics of double-stranded DNA. We model the spontaneous formation of spatially localized openings of a damped and driven DNA chain, and find that linear instabilities lead to dynamic dimerization, while true local strand separations require a threshold amplitude mechanism. Based on our results we argue that a specific terahertz radiation exposure may significantly affect the natural dynamics of DNA, and thereby influence intricate molecular processes involved in gene expression and DNA replication.

description: Il presente lavoro si prefigge di indagare come la produzione normativa comunitaria abbia influenzato il diritto penale nazionale fino a delineare i tratti di un diritto penale di matrice europea. Ai fini dell’individuazione dei rapporti intercorrenti tra i due sistemi, è stata prescelta come chiave di lettura trasversale la materia ambientale: accanto al meccanismo di influenza riflessa, è da ravvisare come proprio in tale ambito si sia sviluppata l’evoluzione di un possibile diritto penale europeo e, dunque, di una esplicita influenza dell’ordinamento sovrannazionale nelle scelte di criminalizzazione nazionali. The present work aims at investigating how the Community legislation has influenced the national criminal law to the point of delineating the features of a criminal law of European origin. In order to identify the relationship between the two systems, the environmental has been chosen as the cross-reading key: in addition to the mechanism of reflected influence, it is precisely in this area that a European criminal law has been developed and, therefore, an explicit influence of the supranational legal order in the domestic choices of criminalization has been implemented.
description: In Chapter I, after having briefly analyzed the concept of environment, the steps of the gradual recognition of a still limited punitive power of the European Union are retraced. More specifically we explore: firstly the various forms of influence that the supranational legislation exerts on the Italian criminal justice system, with particular regard to the so called  “triadic conflicts”; secondly the ruling of the Court of Justice, 13 September 2005, Case C-176/03, where it is stated the Community legislative competence in criminal matters, including the possibility of an express request for criminal protection by means of directives; subsequently, the Directive 2008/99/EC of 19 November 2008 on the protection of the environment through criminal law, which, by requiring Member States to introduce into their national criminal systems some criminal offenses so to enforce more effectively the environmental protection, can been seen as the synthesis between the expansionist pressures from the European Commission and the conservative ones from the Council, as well as also a place of mediation among the different models of indictment in force in the various national systems, providing a minimum common denominator of protection of supranational source;then, the changes introduced by the Legislative Decree of 7 July 2011 n. 121, that transposes the Directive in question, and, lastly, the characteristics of the environmental crime and some issues related to the technique of indictment adopted.

We first discuss how to probe and control Nagaoka ferromagnetism in an array of isolated plaquettes (four lattice sites arranged in a square). Next, we show that introducing a weak interplaquette coupling destroys the ferromagnetic correlations. To overcome this instability we propose to mediate long-range ferromagnetic correlations among the plaquettes via double-exchange processes. Conditions for experimental realization and techniques to detect such states are discussed.

The topological susceptibility from grand canonical simulations in the interacting instanton liquid model: zero temperature calibrations and numerical framework

description: This is the first in a series of papers which ultimately aims on improving on the present estimates on the axion mass by modeling the topological non-perturbative QCD dynamics. Axions couple to instantons and their mass is set by the topological susceptibility whose temperature dependence we estimate with the interacting instanton liquid model (IILM). Since accurate finite temperature instanton calculations have problems and do not consider fluctuations in the topological charge, we develop an improved grand canonical version of the IILM to study topological fluctuations in the quark gluon plasma. In this first paper we will calibrate the model against the topological susceptibility at zero temperature, in the chiral regime of physical quark masses.

title: Amending PHB with Algal Biomass to Enhance Biodegradability
Creators: name: Stoudt, Amanda R.
Publisher: name: Utah State University
Year: 2017

description: Pollution due to petroleum-based plastic is a growing problem all over the world. Petroleum-based plastics that fill landfills and oceans take hundreds of years to degrade. One possible solution to this growing problem is to increase the use of bioplastics. Polyhydroxybutyrate (PHB) is a widely studied bioplastic that is biodegradable in both soil and marine environments. However, PHB use is limited due to its poor mechanical properties. Past researchers have investigated the use of natural additives, primarily different types of plant fibers, to enhance both the mechanical properties and degradation rates of bioplastics. The purpose of this project was to develop a composite bioplastic using PHB and algal biomass in order to enhance the mechanical and degradation properties of PHB.
Composite bioplastic films were formed using a solvent casting method with algal biomass to PHB ratios of 0, 5, 10, and 20% on a weight-to-weight basis. To test the mechanical properties of the biocomposites using a tensile testing machine, the films were cut into dogbones, 3 cm in length. The films were also cut into 2.5 x 3 cm ships that were placed into gas-tight serum vials filled with seawater to measure the degradation rate through CO2 evolution.
The mechanical properties of the biocomposite that were tested include ultimate tensile strength, modulus of elasticity, and percent elongation at break. The ultimate tensile strength and modulus of elasticity of the 20% algae biocomposite were found to be significantly lower than those of the neat, 5, and 10% algae biocomposite. The percent elongation at break of the different biocomposite blends, however, were not significantly different. For the rate of degradation, the neat , 5, and 10% algae biocomposites were found to degrade at significantly different rates, with the 10% blend having the highest rate of degradation followed by the 5% blend and then the neat PHB. The 20% algae biocomposite degraded at a rate that was not significantly different from the degradation rate of the 10% algae biocomposite.
From the results of the mechanical properties and degradation rate testing, the 10% algae biocomposite was found to have mechanical properties similar to those of neat PHB and a degradation rate that was much higher than that of neat PHB. Therefore, it can be concluded that the addition of algal biomass to PHB on a 10% weight-to-weight basis enhances both the mechanical properties and degradation rate of PHB.
The Anthropocene and the Historical Index of Architecture
Creators: name: Gleiter, Joerg
Publisher: name: European Journal of Creative Practices in Cities and Landscapes
Year: 2022

description: In the world of science, the term Anthropocene is widely recognized as the term used to describe the current epoch in the Earth’s geological time scale in which human activities are affecting the Earth system on a scale far beyond natural, geological forces. And architecture is at the center of it. For, on the one hand, human development and architecture are closely linked, for, on the other hand, it is becoming increasingly clear today that architecture has been a major project for reshaping the Earth from the very beginning. Along with devices, tools and machines, architecture is the cultural technique with which the “deficient human being”, in order to compensate for his lack of natural abilities, must intervene in nature with the aim of creating an environment that meets his changing and unchanging needs. Today, however, man’s success story seems to turn into a disaster story, the “architecture of good intentions” seems to turn against man, even though he originally had the best of intentions when he followed the biblical mandate to subdue the earth with his devices, tools, machines, and architecture. From an anthropological perspective, therefore, a different definition of the Anthropocene is emerging. The Anthropocene is the age in which the dialectic between man’s well-intentioned intentions and the destructive consequences for the Earth system clearly emerges. What becomes visible is that the relationship between architecture and the environment, or between humans and the Earth system, is inherently fractured and contradictory, and that this contradiction is constitutive of human existence. It follows that the Anthropocene requires a critical questioning of the dialectic of human and system earth inherent in culture.

description: In this work we study a state which is a random mixture of a two qubit subsystem of a $N$-qubit W state and GHZ state. We analyze several possibilities like separability criterion (Peres-Horodecki criterion [14,15]), non violation of Bell's inequality [6]($M(ρ)<1$)and teleportation fidelity [1,2,3,4] ($(F_{max}>{2/3})$) for this state. We also obtain a relationship between $N$ (number of qubits) and $p$ (the classical probability of random mixture) for each of these possibilities. Finally we present a detailed analysis of all these possibilities for $N=3,4,5$ qubit systems. We also report that for N=3 and $p\in(.75,1]$, this entangled state can be used as a teleportation channel without violating Bell's inequality.

Maternal Smoking Impact on the Delivery Cost: a population-based study in the Emilia-Romagna region

Subjects: SECS-S/03 Statistica economica

description: This doctoral thesis is devoted to the study of the causal effects of the maternal smoking on the delivery cost. The interest of economic consequences of smoking in pregnancy have been studied fairly extensively in the USA, and very little is known in European context.
To identify the causal relation between different maternal smoking status and the delivery cost in the Emilia-Romagna region two distinct methods were used. The first - geometric multidimensional - is mainly based on the multivariate approach and involves computing and testing the global imbalance, classifying cases in order to generate well-matched comparison groups, and then computing treatment effects. The second - structural modelling - refers to a general methodological account of model-building and
model-testing. The main idea of this approach is to decompose the global mechanism into sub-mechanisms though a recursive decomposition of a multivariate distribution.

description: Non-minimally coupled scalar field models of dark energy are equivalent to an interacting quintessence in the Einstein's frame. Considering two special important choices of the potential of the scalar field, i.e. nearly flat and thawing potential, one has an analytical expression for the equation of state parameter as a function of the density parameter of the scalar field for any choice. Here we investigate the non-minimal quintessence model by applying the method of statefinder diagnosis to it and plotting the evolutionary trajectories of the statefinder parameters.

description: We find that ferromagnetism can be induced in carbon nanotubes (CNTs) by introducing hydrogen. Multiwalled CNTs grown inside porous alumina templates contain a large density of defects resulting in significant hydrogen uptake when annealed at high temperatures. This hydrogen incorporation produces H-complex and adatom magnetism which generates a sizeable ferromagnetic moment and a Curie temperature near Tc=1000 K. We studied the conditions for the incorporation of hydrogen, the temperature-dependent magnetic behavior, and the dependence of the ferromagnetism on the size of the nanotubes.

Aesthetics and Dreams in the Absence of Epoch. Bernard Stiegler’s Bifurcation of the Anthropocene
Creators: name: Nigrelli, Claudia
Publisher: name: European Journal of Creative Practices in Cities and Landscapes
Year: 2022

description: In this article, we analyze the concept of Anthropocene in Bernard Stiegler's work through the cross-reading of the possibility of aesthetic experience and of what Stiegler calls a war against this experience and the function of dreams. The aesthetic experience as the experience of the exosomatisation is addressed in the books concerning The Symbolic Misery; the function of dreams is addressed in the book The Age of Disruption, in which the Anthropocene appears to be “an absence of epoch”. For Stiegler, this concept implies the consideration of a catastrophe that is not only ecological but also psychic and collective, that is, the impossibility of thinking of an alternative present to the one imposed by the capitalist economy. At the center of Stiegler's analysis is the intertwining of aesthetics and technics as what allows individuation and the political-philosophical reflection on technics as what is necessary for human life but that also consists in a risk, the one of losing the possibility of cultivating reason as what allows to live a life worth living, to cultivate the singularity and the unexpected as the ability to bifurcate the paths of the possible.

title: Electrospun Spiderskin Bandage for Epidermal Protection and Recovery
Creators: name: Paskett, Michael David
Publisher: name: Utah State University
Year: 2017

description: Spider silk is one of nature's most promising biomaterial s for a variety of applications, however, due to the inability to farm spiders, transgenic hosts are required for large-scale production. With the unique combination of strength, elasticity, and biocompatibility, spider silk has an incredible potential for use in the human body. This study was conducted to merge two major applications of spider silk for the creation of a novel bandaging product. Electrospinning technology was utilized to create a spider silk/polymer bandage matrix to be applied with an aqueous spider silk skin adhesive.
In designing the bandaging matrix , the mechanical properties of the electrospun silk were evaluated against commercially-available product s and known values of human skin. The chosen formulation had physical properties more comparable human skin than commercially-available products. The aqueous adhesive was tested in conjunction with the electro spun matrix for its adhesion and found comparable to commercial products. The durability of the bandage was tested via cyclic stresses and found analogous to commercial products. The common antimicrobial chlorhexidine was incorporated into the adhesive and had a release profile lasting about 4 days. With this incorporation into the aqueous adhesive, the adhesive can be reapplied to provide additional antimicrobial protection, a necessity in the healthcare industry. The bandaging showed no signs of inhibiting mammalian cell proliferation under cytotoxicity testing.
The final product, deemed "SpiderSkin," presents a unique bandaging solution capable of providing a healthy environment for the regeneration of epidermal tissue, while protecting the wound from outside infection , and providing mechanical stability similar to that of human skin.

description: We evaluate theoretically the thermoelectric efficiency of the layered perovskite Sr$_2$Nb$_2$O$_7$ via calculations of the electronic structure and transport coefficients within density-functional theory and Bloch-Boltzmann relaxation-time transport theory. The predicted figure-of-merit tensor $ZT$, computed with energy-, chemical potential- and temperature-dependent relaxation times, has one component increasing monotonically from around 0.4 at room temperature to 2.4 at 1250 K at an optimal carrier density around 2$\times$10$^{20}$ cm$^{-3}$, while the other components are small. The Seebeck coefficient is about 250 to 300 $μ$V/K at optimal doping, and reaches 800 $μ$V/K at lower doping. We provide a {\tt python} code implementing various approximations to the energy-dependent relaxation time transport, which can be used to address different systems with an appropriate choice of material parameters.
Inhabiting the Anthropocene. Aesthetics of Everyday Life in Times of Crisis
Creators: name: Eghbali, Arshia
Publisher: name: European Journal of Creative Practices in Cities and Landscapes
Year: 2022

description: Reconciling the seemingly incompatible concepts of the Anthropocene and the everyday, this paper argues and demonstrates that (1) despite the disconcerting effects of its truly planetary scale, the Anthropocene is not absent or invisible in the realm of everyday life; (2) the everyday is not simply a neutral background solely meant for times of stability, but it is in fact a dynamic system that responds to various scales of change and absorbs the new and the unfamiliar into the familiar. Moreover, the paper also shows that the ways in which change is lived and navigated on an everyday scale, in times of the covid-19 pandemic and climate change, are a unique field for aesthetic enquiry. Everyday material objects such as tote bags, water bottles, masks, and habits like working from home and second-hand wearing are discussed as examples of the everyday experience of relating to the Anthropocene and its crises.

Here we develop some applications of this theory to cluster algebras. As shown in the "Cluster algebras IV" paper, the cluster algebra structure is to a large extent controlled by a family of integer vectors called g-vectors, and a family of integer polynomials called F-polynomials. In the case of skew-symmetric exchange matrices we find an interpretation of these g-vectors and F-polynomials in terms of (decorated) representations of quivers with potentials. Using this interpretation, we prove most of the conjectures about g-vectors and F-polynomials made in loc. cit.

title: Increasing Parenting Knowledge: A Pilot Study

description: Research shows that parenting interventions make a significant difference in the lives of children with behavioral and emotional problems (de Graaf et al., 2008a; de Graaf et al., 2008b; Phaneuf & McIntyre, 2011; Roberts et al., 2006; Whittingham, Sofronoff, Sheffield, & Sanders, 2009). However, not all parents need intensive interventions. There is little research that has evaluated the effectiveness of a brief parenting handout intervention on parenting knowledge. The goal of this study was to determine if a brief informational handout about parenting increased parenting knowledge in college students. Students were asked to complete the pre-intervention survey that measured their initial parenting knowledge and asked about their demographics. They were then randomly assigned to read either a handout on effective behavior management at home (intervention group) or developmental milestones (control group). Finally, they were asked to complete the post-intervention survey that measured their parenting knowledge a second time. An independent sample t-test comparing mean change between groups on Knowledge of Effective Parenting Practices (KEPS), using raw change scores, was conducted. There was no statistically significant difference between the group that received the effective behavior management handout (M=0.13; SD=1.98) and the group that received the developmental milestones handout (M=-.10; SD=2.72); t(151)=0.61, p=0.542. This indicates that the behavior management intervention handout was not effective in increasing parenting knowledge in college students. However, participants found the information in the handout to be more effective than the developmental milestones handout; t(151)=4.56, p

description: Binding of ligands is often crucial for function yet the effects of ligand binding on the mechanical stability and energy landscape of proteins are incompletely understood. Here we use a combination of single-molecule optical tweezers and MD simulations to investigate the effect of ligand binding on the energy landscape of acyl-coenzyme A (CoA) binding protein (ACBP). ACBP is a topologically simple and highly conserved four-alpha-helix bundle protein that acts as an intracellular transporter and buffer for fatty-acyl CoA and is active in membrane assembly. We have previously described the behavior of ACBP under tension, revealing a highly extended transition state (TS) located almost halfway between the unfolded and native states. Here, we performed force-ramp and force-jump experiments, in combination with advanced statistical analysis, to show that octanoyl-CoA binding increases the activation free energy for the unfolding reaction of ACBP without affecting the position of the transition state along the reaction coordinate. It follows that ligand binding enhances the mechanical resistance and thermodynamic stability of the protein, without changing its mechanical compliance. Steered molecular dynamics simulations allowed us to rationalize the results in terms of key interactions that octanoyl-CoA establishes with the four alpha-helices of ACBP and showed that the unfolding pathway is marginally affected by the ligand. The results show that ligand-induced mechanical stabilization effects can be complex and may prove useful for the rational design of stabilizing ligands.

The lattice thermal conductivity is estimated from a model employing the ab initio phonon and Grüneisen-parameter spectrum. The main source of the large $ZT$ is the significant power factor which correlates with a large band complexity factor. We also suggest a possible $n$-type dopant for the material based on ab initio calculations.

description: The aim of this essay is to show the sense and the limits of some of the contemporary critiques of the idea of the world. It will be structured as follows: in a first paragraph, we will show the conceptual structure of these critiques as they take shape in Object Oriented Ontology (OOO), especially in Timothy Morton's work, Hyperobjects. In a second, we will focus on the two main difficulties that such critical work encounters. In a third, finally, we will show the possibilities, aesthetic and political, of a revisited concept of world.

description: We have studied the mass hierarchy with atmospheric neutrinos considering the muon energy and zenith angle of the event at the magnetized iron calorimeter detector. For $χ^2$ analysis we have migrated the number of events from neutrino energy and zenith angle bins to muon energy and zenith angle bins using the two-dimensional energy-angle correlated resolution functions. The binning of data is made in two-dimensional grids of $\log_{10} E - L^{0.4}$ plane to get a better reflection of the oscillation pattern in the $χ^2$ analysis. Then the $χ^2$ is marginalized considering all possible systematic uncertainties of the atmospheric neutrino flux and cross section. The effects of the ranges of oscillation parameters on the marginalization are also studied. The lower limit of the range of $θ_{13}$ for marginalization is found to be very crucial in determining the sensitivity of hierarchy for a given $θ_{13}$. Finally, we show that one can discriminate atmospheric neutrino mass hierarchy at $>$90% C.L. if the lower limit of $θ_{13} \ge 5^\circ$.

description: Long gamma-ray bursts (GRBs) are considered to be originated from core collapse of massive stars. It is believed that the afterglow property is determined by the density of the material in the surrounding interstellar medium. Therefore, the circumburst density can be used to distinguish between an interstellar wind $n(R) \propto R^{\rm -k}$, and a constant density medium (ISM), $n(R) = const$. Previous studies with different afterglow samples, show that the circumburst medium of GRBs is neither simply supported by an interstellar wind, nor completely favored by an ISM. In this work, our new sample is consisted of 39 GRBs with smoothly onset bump-like features in early X-ray afterglows, in which 20 GRBs have the redshift measurements. By using a smooth broken power law function to fit the bumps of X-ray light curves, we derive the full width at half-maximum (FWHM) as the feature width ($ω$), as well as the rise and decay time scales of the bumps ($T_{\rm r}$ and $T_{\rm d}$). The correlations between the timescales of X-ray bumps are similar to those found previously in the optical afterglows. Based on the fireball forward shock (FS) model of the thin shell case, we obtain the distribution of the electron spectral index $p$, and further constrain the medium density distribution index $k$. The new inferred $k$ is found to be concentrated at 1.0, with a range from 0.2 to 1.8. This finding is consistent with previous studies. The conclusion of our detailed investigation for X-ray afterglows suggests that the ambient medium of the selected GRBs is not homogeneous, i.e., neither ISM nor the typical interstellar wind.

description: In this paper, the complexities in the relationship between rainfall and sea surface temperature (SST) anomalies during the winter monsoon (November-January) over India were evaluated statistically using scatter plot matrices and autocorrelation functions.Linear as well as polynomial trend equations were obtained and it was observed that the coefficient of determination for the linear trend was very low and it remained low even when polynomial trend of degree six was used. An exponential regression equation and an artificial neural network with extensive variable selection were generated to forecast the average winter monsoon rainfall of a given year using the rainfall amounts and the sea surface temperature anomalies in the winter monsoon months of the previous year as predictors. The regression coefficients for the multiple exponential regression equation were generated using Levenberg-Marquardt algorithm. The artificial neural network was generated in the form of a multiplayer perceptron with sigmoid non-linearity and genetic-algorithm based variable selection. Both of the predictive models were judged statistically using the Willmott index, percentage error of prediction, and prediction yields. The statistical assessment revealed the potential of artificial neural network over exponential regression.

description: Gravitational wave (GW) memory is an important prediction of general relativity. Existing works on the GW memory detection focus on the waveform analysis. It is hard for waveform analysis method to detect the GW memory due to its quasi-direct current behavior and weakness. We implement a completely different scheme in this work to estimate the GW memory. In this scheme, we firstly apply the Bondi-Metzner-Sachs method to calculate the GW memory of binary black hole based on numerical relativity simulation. Then we construct a surrogate model to relate binary black hole's parameters and the GW memory. Afterwards we apply this surrogate model together with Bayesian techniques to estimate the GW memory of the 48 binary black hole events recorded in GWTC-2. The GW memory corresponding to the all 48 events has been estimated. The most interesting results are for GW190814. The corresponding GW memory is about $-1\times10^{-23}$ and $1\times10^{-23}$ for Hanford detector and Livingston detector respectively. At the same time we find with 3$σ$ C.L. that the memory strain of GW190814 is negative on Hanford detector while positive on Livingston detector.

description: We present an analysis on the geometrical place formed by the set of maxima of the trajectories of a projectile launched in a media with linear drag. Such a place, the locus of apexes, is written in term of the Lambert $W$ function in polar coordinates, confirming the special role played by this function in the problem. In order to characterize the locus, a study of its curvature is presented in two parameterizations, in terms of the launch angle and in the polar one. The angles of maximum curvature are compared with other important angles in the projectile problem. As an addendum, we find that the synchronous curve in this problem is a circle as in the drag-free case.

description: We investigate theoretically the Seebeck effect in materials close to a ferromagnetic quantum critical point to explain anomalous behaviour at low temperatures. It is found that the main effect of spin fluctuations is to enhance the coefficient of the leading $T$-linear term, and a quantum critical behaviour characterized by a spin-fluctuation temperature appears in the temperature dependence of correction terms as in the specific heat.

The melting behavior of lutetium aluminum perovskite LuAlO3

description: DTA measurements with mixtures of aluminum oxide and lutetium oxide around the 1:1 perovskite composition were performed up to 1970 deg. C. A peak with onset 1901 deg C was due to the melting of the eutectic Lu4Al2O9 (monoclinic phase) and LuAlO3 (perovskite). Neither peritectic melting of the perovskite nor its decomposition in the solid phase could be resolved experimentally. The maximum of the eutectic peak size is near x=0.44, on the Lu-rich side of the perovskite, which is consistent with the conclusion that LuAlO3 melts peritectically at ca. 1907 deg. C as proposed by Wu, Pelton, J. Alloys Compd. 179 (1992) 259. Thermodynamic equilibrium calculations reveal, that under strongly reducing conditions (oxygen partial pressure <10^{-13} bar) aluminum(III) oxide can be reduced to suboxides or even Al metal. It is shown that under such conditions a new phase field with liquid Al can appear.

description: A general property of the relation between the dynamics of the reduced purity and correlations is investigated in quantum mechanical systems. We show that a non-zero time-derivative of the reduced purity of a system implies the existence of non-zero correlations with its environment under any unbounded Hamiltonians with finite variance. This shows the role of local dynamical information on the correlations, as well as the role of correlations in the mechanism of purity change.
