description: With the introduction of the Corporate Sustainability Reporting Directive (CSRD) and its consequent European Sustainability Reporting Standards (ESRS) the European Union aims to foster the awareness of sustainability even in corporate contexts. Potential and existing stakeholders and investors, civil society organizations or the public shall be informed about which impacts and opportunities associated with sustainability a company deals with. Adding to the companies ́ reporting requirements, the CSRD aims to consider additional aspects, such as double materiality and a broader scope of enterprises. Moreover, by requiring a third party to audit and control the reports, the compliance of the firms is evaluated. Since the first reports of the CSRD will be submitted in 2025, affected firms are in the midst of preparations and reporting activities. Due to the novelty of the directive and the standards, open questions, assumptions, and speculations have come up. Hence, this research paper aims to identify such concerns and to evaluate them. In addition, the impacts and opportunities faced by ICT enterprises in Austria will be assessed.

A remarkable identity in class numbers of cubic rings

description: In 1997, Y. Ohno empirically stumbled on an astoundingly simple identity relating the number of cubic rings $h(D)$ of a given discriminant $D$, over the integers, to the number of cubic rings $h'(D)$ of discriminant $-27D$ in which every element has trace divisible by 3: $h'(D) = h(D)$, if $D < 0$, and $h'(D) = 3h(D)$ if $D > 0$, where in each case, rings are weighted by the reciprocal of their number of automorphisms. This allows the functional equations governing the analytic continuation of the Shintani zeta functions (the Dirichlet series built from the values of $h$ and $h'$) to be put in self-reflective form. In 1998, J. Nakagawa verified Ohno's conjecture. We present a new proof of the identity that uses the main ingredients of Nakagawa's proof (binary cubic forms, recursions, and class field theory), as well as one of Bhargava's celebrated higher composition laws, while aiming to stay true to the stark elegance of the identity.

description: In this paper, we analyze the structural properties of $Z=132$ and $Z=138$ superheavy nuclei within the ambit of axially deformed relativistic mean-field framework with NL$3^{*}$ parametrization and calculate the total binding energies, radii, quadrupole deformation parameter, separation energies, density distributions. We also investigate the phenomenon of shape coexistence by performing the calculations for prolate, oblate and spherical configurations. For clear presentation of nucleon distributions, the two-dimensional contour representation of individual nucleon density and total matter density has been made. Further, a competition between possible decay modes such as $α$-decay, $β$-decay and spontaneous fission of the isotopic chain of superheavy nuclei with $Z=132$ within the range 312 $\le$ A $\le$ 392 and 318 $\le$ A $\le$ 398 for $Z=138$ is systematically analyzed within self-consistent relativistic mean field model. From our analysis, we inferred that the $α$-decay and spontaneous fission are the principal modes of decay in majority of the isotopes of superheavy nuclei under investigation apart from $β$ decay as dominant mode of decay in $^{318-322}138$ isotopes.

description: Vor ein paar Jahren sorgte eine Bibliographie für Furore, die sich eines Autors annahm, der, so bekannt er im 19. Jahrhundert war, selbst bei Fachleuten weitgehend vergessen war: Karl Gutzkow. Selbst das Feuilleton in seiner freundlich-wohlmeinenden Eitelkeit nahm sich plötzlich dieses Schriftstellers an, dessen literarische Welt die bibliographische Glanzarbeit für einige historische Augenblicke ans Tageslicht gebracht hatte. Peter Rühmkorf, der 2004 sein 75. Lebensjahr vollendete, gehört nicht zu den Vergessenen. Seit Ende der 1970er Jahre fällt sein Name unweigerlich, wenn über die Literatur der Bundesrepublik gesprochen oder geschrieben wird. Er hat sie Jahrzehnte begleitet, ist von ihr geprägt worden und hat sie geprägt. Die literarische Öffentlichkeit hat ihm, nach Jahren der Sperrigkeit, endlich mit Literaturpreisen dafür gedankt. Spätestens 1995 mit Tabu I, der Veröffentlichung seiner Tagebücher 1989–1991, wurde klar, daß sich hier ein Werk zu einem Lebenswerk abzurunden begann. Nicht getragen von Gunst und Begünstigung, frei vom Sog kurzfristiger Modernität, die den Tag kaum überlebt, und begabt mit jenem langen Atem, den anhaltende Kreativität benötigt.

Year: 2016
Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: In this paper, the classical Schrödinger equation, which allows the study of classical dynamics in terms of wave functions, is analyzed theoretically and numerically. First, departing from classical (Newtonian) mechanics, and assuming an additional single-valued condition for the Hamilton's principal function, the classical Schrödinger equation is obtained. This additional assumption implies inherent non-classical features on the description of the dynamics obtained from the classical Schrödinger equation: the trajectories do not cross in the configuration space. Second, departing from Bohmian mechanics and invoking the quantum-to-classical transition, the classical Schrödinger equation is obtained in a natural way for the center of mass of a quantum system with a large number of identical particles. This quantum development imposes the condition of dealing with a narrow wave packet, which implicitly avoids the non-classical features mentioned above. We illustrate all the above points with numerical simulations of the classical and quantum Schrödinger equations for different systems.

description: Improvement in magnetic and electrical properties of multiferroic BiFeO$_3$ in conjunction with their dependence on particle size is crucial due to its potential applications in multifunctional miniaturized devices. In this investigation, we report a study on particle size dependent structural, magnetic and electrical properties of sol-gel derived Bi$_{0.9}$Ba$_{0.1}$FeO$_3$ nanoparticles of different sizes ranging from $\sim$ 12 to 49 nm. The substitution of Bi by Ba significantly suppresses oxygen vacancies, reduces leakage current density and Fe$^{2+}$ state. An improvement in both magnetic and electrical properties is observed for 10 % Ba-doped BiFeO$_3$ nanoparticles compared to its undoped counterpart. The saturation magnetization of Bi$_{0.9}$Ba$_{0.1}$FeO$_3$ nanoparticles increase with reducing particle size in contrast with a decreasing trend of ferroelectric polarization. Moreover, a first order metamagnetic transition is noticed for $\sim$ 49 nm Bi$_{0.9}$Ba$_{0.1}$FeO$_3$ nanoparticles which disappeared with decreasing particle size. The observed strong size dependent multiferroic properties are attributed to the complex interaction between vacancy induced crystallographic defects, multiple valence states of Fe, uncompensated surface spins, crystallographic distortion and suppression of spiral spin cycloid of BiFeO$_3$.

description: We employ two Tight-Binding (TB) approaches to study the electronic structure and hole or electron transfer in B-DNA monomer polymers and dimer polymers made up of $N$ monomers (base pairs): (I) at the base-pair level, using the on-site energies of base pairs and the hopping integrals between successive base pairs, i.e., a wire model and (II) at the single-base level, using the on-site energies of the bases and the hopping integrals between neighboring bases, i.e., an \textit{extended} ladder model since we also include diagonal hoppings. We solve a system of $MD$ ("matrix dimension") coupled equations [(I) $MD$ = $N$, (II) $MD$ = $2N$] for the time-independent problem, and a system of $MD$ coupled $1^\text{st}$ order differential equations for the time-dependent problem. We study the HOMO and the LUMO eigenspectra, the occupation probabilities, the Density of States (DOS) and the HOMO-LUMO gap as well as the mean over time probabilities to find the carrier at each site [(I) base pair or (II) base)], the Fourier spectra, which reflect the frequency content of charge transfer (CT) and the pure mean transfer rates from a certain site to another. The two TB approaches give coherent, complementary aspects of electronic properties and charge transfer in B-DNA monomer polymers and dimer polymers.

description: This study investigates the water management structures and social relations that centred around a specific qanāt line in a rural setting in Iran during the Safavid period, specifically in the mid-17th c. CE. The setting is northwest of Isfahān, near Varkān, at a site called Mobārrak Ābād. The method combines analysis of documentary evidence and remote sensing of historical aerial photography. The documentary evidence provides administrative details of a suyūrghāl grant to Mohammad Beig E’temād-al-Dowleh by Shah ‘Abbās II. In combining this with the physical characteristics of the qanāt of Mobārrak Ābād, as derived from the aerial photograph, I provide identification and analysis of the two canals providing water beyond the garden and the use of the water derived from the qanāt for agricultural irrigation and in Aranjon’s village infrastructure. The conclusions discuss the material conditions in the periphery of the prosperous and fertile Isfahān region and provide a relative dating to the qanāt and associated infrastructure. The personal and social relations that can be derived from this evidence are relations of personal and economic dependency between Mohammad Beig E´temād-al-Dowleh and the Shah on the one hand, as well as the labour relations between the peasant population living with and from the qanāt who maintain this infrastructure and the administrative superstructure on the other. The article thus provides new insights into an under-investigated subject and region in the period.

description: Literature related to European transport and slaughter processes were included in this systematic review. The publication period is limited to the past twelve years since the European Animal Welfare Transport Regulation was enacted in 2009. Three different databases were used. The final screening resulted in the inclusion of 19 articles in this review. When handling cattle during transport and slaughter, personnel have an important impact and may inflict stress on the animals. Other factors, such as the group composition and health status prior to transport, can have a strong negative effect on animal welfare. At the abattoir, constructional conditions and the resulting environmental influences can have a negative impact on welfare as well. These include increased noise levels due to the lack of noise dampening and changing light conditions. Stress in cattle can be assessed, e.g., by measuring stress hormones or heart rate. Effective stunning is an important welfare-relevant step in the slaughtering process. Some signs of unconsciousness, such as immediate body collapse or absence of the corneal reflex, can be easily assessed. Expertise and continuous training of all personnel involved are important measures in stress reduction.

Structural Phase Stability in Fluorinated Calcium Hydride

description: In order to improve the hydrogen storage properties of calcium hydride (CaH2), we have tuned its thermodynamical properties through fluorination. Using ab-initio total energy calculations based on density functional theory, the structural stability, electronic structure and chemical bonding of CaH2-xFx systems are investigated. The phase transition of fluorinated systems from orthorhombic to cubic structure has been observed at 18% fluorine doped CaH2. The phase stability analysis shows that CaH2-xFx systems are highly stable and the stability is directly correlating with their ionicity. Density of states (DOS) plot reveals that CaH2-xFx systems are insulators. Partial DOS and charge density analyses conclude that these systems are governed by ionic bonding. Our results show that H closer to F can be removed more easily than that far away from F and this is due to disproportionation induced in the bonding interaction by fluorination.

When the latter magnetic field is small enough, we show that the groundstate solution is unique up to magnetic translations and rotations in the complex phase space, that groundstate solutions share the rotational invariance of the magnetic field and that the presence of a magnetic field induces a Gaussian decay. In this small magnetic field régime, the corresponding ground-energy is a convex differentiable function of the magnetic field.

description: The acronym IBIC (Ion Beam Induced Charge) was coined in early 1990's to indicate a scanning microscopy technique which uses MeV ion beams as probes to image the basic electronic properties of semiconductor materials and devices. Since then, IBIC has become a widespread analytical technique to characterize materials for electronics or for radiation detection, as testified by more than 200 papers published so far in peer-reviewed journals. Its success stems from the valuable information IBIC can provide on charge transport phenomena occurring in finished devices, not easily obtainable by other analytical techniques. However, IBIC analysis requires a robust theoretical background to correctly interpret experimental data. In order to illustrate the importance of using a rigorous mathematical formalism, we present in this paper a benchmark IBIC experiment aimed to test the validity of the interpretative model based on the Gunn's theorem and to provide an example of the analytical capability of IBIC to characterize semiconductor devices.

description: In this article, we generalize known formulas for crossing probabilities. Prior crossing results date back to J. Cardy's prediction of a formula for the probability that a percolation cluster in two dimensions connects the left and right sides of a rectangle at the percolation critical point in the continuum limit. Here, we predict a new formula for crossing probabilities of a continuum limit loop-gas model on a planar lattice inside a $2N$-sided polygon. In this model, boundary loops exit and then re-enter the polygon through its vertices, with exactly one loop passing once through each vertex, and these loops join the vertices pairwise in some specified connectivity through the polygon's exterior. The boundary loops also connect the vertices through the interior, which we regard as a crossing event. For particular values of the loop fugacity, this formula specializes to FK cluster (resp. spin cluster) crossing probabilities of a critical $Q$-state random cluster (resp. Potts) model on a lattice inside the polygon in the continuum limit. This includes critical percolation as the $Q=1$ random cluster model. These latter crossing probabilities are conditioned on a particular side-alternating free/fixed (resp. fluctuating/fixed) boundary condition on the polygon's perimeter, related to how the boundary loops join the polygon's vertices pairwise through the polygon's exterior in the associated loop-gas model. For $Q\in\{2,3,4\}$, we compare our predictions of these random cluster (resp. Potts) model crossing probabilities in a rectangle ($N=2$) and in a hexagon ($N=3$) with high-precision computer simulation measurements. We find that the measurements agree with our predictions very well for $Q\in\{2,3\}$ and reasonably well if $Q=4$.

description: The widespread use of direct current (DC) motors has persisted despite advancements in power electronics devices. These motors find application not only in industrial drives and solar-powered electric vehicles but also in everyday household devices. This work delves into the speed control of Separately Excited DC Motors, exploring the efficacy of classical Proportional Integral (PI) Controllers alongside advanced soft computing Intelligent Controllers, namely Fuzzy Logic Controllers (FLC), Adaptive Neuro Fuzzy Inference System (ANFIS) Based Controllers, and Artificial Neural Network (ANN) Based Controllers. The investigation is carried out using MATLAB and the Simulink environment. DC motors convert electrical energy into mechanical work, facilitating a variety of tasks. They are classified based on the excitation of field windings: Self Excited DC Motors derive their field coil power from the same DC source as the armature coils, while Separately Excited DC Motors receive field power from a distinct source. Speed control is crucial for achieving desired operational levels in various applications. Two primary methods are employed: armature voltage control and field current control. In this study, the Armature voltage control technique is employed for speed control, comparing the performance of PI controllers with soft computing approaches. The study builds on existing research, drawing from literature such as the use of Fuzzy Logic Controllers to manage DC motor operations.

description: In this paper we study the abilities of an atmospherical mesoscale model in forecasting the classical atmospherical parameters relevant for astronomical applications at the surface layer (wind speed, wind direction, temperature, relative humidity) on the Large Binocular Telescope (LBT) site - Mount Graham, Arizona. The study is carried out in the framework of the ALTA project aiming at implementing an automated system for the forecasts of atmospherical parameters (Meso-Nh code) and the optical turbulence (Astro-Meso-Nh code) for the service-mode operation of the LBT. The final goal of such an operational tool is to provide predictions with high time frequency of atmospheric and optical parameters for an optimized planning of the telescope operation (dome thermalization, wind-dependent dome orientation, observation planning based on predicted seeing, adaptive optics optimization, etc...). Numerical simulations are carried out with the Meso-Nh and Astro-Meso-Nh codes, which were proven to give excellent results in previous studies focused on the two ESO sites of Cerro Paranal and Cerro Armazones (MOSE Project). In this paper we will focus our attention on the comparison of atmospherical parameters forescasted by the model close to the ground with measurements taken by the observatory instrumentations and stored in the LBT telemetry in order to validate the numerical predictions. As previously done for Cerro Paranal (Lascaux et al., 2015), we will also present an analysis of the model performances based on the method of the contingency tables, that allows us to provide complementary key information with the respect to the bias and RMSE (systematic and statistical errors), such as the percentage of correct detection and the probability to obtain a correct detection inside a defined interval of values.

description: In this note, I revisit integrals over $\SU(N)$ of the form $ \int DU\, U_{i_1j_1}\cdots U_{i_pj_p}\Ud_{k_1l_1}\cdots \Ud_{k_nl_n}$. While the case $p=n$ is well known, it seems that explicit expressions for $p=n+N$ had not appeared in the literature. Similarities and differences, in particular in the large $N$ limit, between the two cases are discussed

The Indeterminate "We": A Case against Unilateral Border Control

Subjects: subject: Unilateral border control
subject: territorial exclusion
subject: civic boundary drawing

description: Extant theories of territorial exclusion justify the right to unilateral border control based on an interest exclusively shared among a political community. This justificatory approach introduces civic boundary drawing, i.e., the identification of the “we,” into discussions about free movement and immigration control. I first set out a normative framework—consisting of the higher-order constraints of context consistency and non-arbitrariness—that structures my evaluation of the different civic boundary drawing criteria offered by three prominent accounts of unilateral border control, including Wellman’s freedom of association account, Pevnick’s associative ownership account, and Blake’s jurisdictional theory of exclusion. I then argue that there is no satisfactory way of civic boundary drawing because the substantive requirements respectively inferred from the two higher-order constraints contradict with each other. Due to this internal incoherence in the current justificatory approach, the identified “we” is indeterminate, making us unable to capture the interest internally shared among this indeterminate group. It is thus implausible to motivate a defense for the right to unilateral border control based on the ungroundedly-assumed internally shared interest.

description: Optics for future X-ray telescopes will be characterized by very large aperture and focal length, and will be made of lightweight materials like glass or silicon in order to keep the total mass within acceptable limits. Optical modules based on thin slumped glass foils are being developed at various institutes, aiming at improving the angular resolution to a few arcsec HEW. Thin mirrors are prone to deform, so they require a careful integration to avoid deformations and even correct forming errors. On the other hand, this offers the opportunity to actively correct the residual deformation: a viable possibility to improve the mirror figure is the application of piezoelectric actuators onto the non-optical side of the mirrors, and several groups are already at work on this approach. The concept we are developing consists of actively integrating thin glass foils with piezoelectric patches, fed by voltages driven by the feedback provided by X-rays. The actuators are commercial components, while the tension signals are carried by a printed circuit obtained by photolithography, and the driving electronic is a multi-channel low power consumption voltage supply developed in-house. Finally, the shape detection and the consequent voltage signal to be provided to the piezoelectric array are determined in X-rays, in intra-focal setup at the XACT facility at INAF/OAPA. In this work, we describe the manufacturing steps to obtain a first active mirror prototype and the very first test performed in X-rays.

description: Belief networks represent a powerful approach to problems involving probabilistic inference, but much of the work in this area is software based utilizing standard deterministic hardware based on the transistor which provides the gain and directionality needed to interconnect billions of them into useful networks. This paper proposes a transistor like device that could provide an analogous building block for probabilistic networks. We present two proof-of-concept examples of belief networks, one reciprocal and one non-reciprocal, implemented using the proposed device which is simulated using experimentally benchmarked models.

Generalized Maxwell equations and charge conservation censorship

description: The Aharonov-Bohm electrodynamics is a generalization of Maxwell theory with reduced gauge invariance. It allows to couple the electromagnetic field to a charge which is not locally conserved, and has an additional degree of freedom, the scalar field $S=\partial_αA^α$, usually interpreted as a longitudinal wave component. By re-formulating the theory in a compact Lagrangian formalism, we are able to eliminate $S$ explicitly from the dynamics and we obtain generalized Maxwell equation with interesting properties: they give $\partial_μF^{μν}$ as the (conserved) sum of the (possibly non-conserved) physical current density $j^ν$, and a "secondary" current density $i^ν$ which is a non-local function of $j^ν$. This implies that any non-conservation of $j^ν$ is effectively "censored" by the observable field $F^{μν}$, and yet it may have real physical consequences. We give examples of stationary solutions which display these properties. Possible applications are to systems where local charge conservation is violated due to anomalies of the ABJ kind or to macroscopic quantum tunnelling with currents which do not satisfy a local continuity equation.

description: We develop an approach to characterize excited states of disordered many-body systems using spatially resolved structures of entanglement. We show that the behavior of the mutual information (MI) between two parties of a many-body system can signal a qualitative difference between thermal and localized phases -- MI is finite in insulators while it approaches zero in the thermodynamic limit in the ergodic phase. Related quantities, such as the recently introduced Codification Volume (CV), are shown to be suitable to quantify the correlation length of the system. These ideas are illustrated using prototypical non-interacting wavefunctions of localized and extended particles and then applied to characterize states of strongly excited interacting spin chains. We especially focus on evolution of spatial structure of quantum information between high temperature diffusive and many-body localized phases believed to exist in these models. We study MI as a function of disorder strength both averaged over the eigenstates and in time-evolved product states drawn from continuously deformed family of initial states realizable experimentally. As expected, spectral and time-evolved averages coincide inside the ergodic phase and differ significantly outside. We also highlight dispersion among the initial states \emph{within} the localized phase -- some of these show considerable generation and delocalization of quantum information.

description: In this paper, we show that the twisted Poincaré duality between Poisson homology and cohomology can be derived from the Serre invertible bimodule. This gives another definition of a unimodular Poisson algebra in terms of its Poisson Picard group. We also achieve twisted Poincaré duality for Hochschild (co)homology of Poisson bimodules using rigid dualizing complex. For a smooth Poisson affine variety with the trivial canonical bundle, we prove that its enveloping algebra is a Calabi-Yau algebra if the Poisson structure is unimodular.

description: We report on the characterization of silica aerogel thermal optical nonlinearity, obtained by z-scan technique. The results show that typical silica aerogels have nonlinear optical coefficient similar to that of glass $(\simeq 10^{-12} $m$^2/$W), with negligible optical nonlinear absorption. The non\-li\-near coefficient can be increased to values in the range of $10^{-10} $m$^2/$W by embedding an absorbing dye in the aerogel. This value is one order of magnitude higher than that observed in the pure dye and in typical highly nonlinear materials like liquid crystals.

description: The inverse problem method is tested for a class of monomer-dimer statistical mechanics models that contain also an attractive potential and display a mean-field critical point at a boundary of a coexistence line. The inversion is obtained by analytically identifying the parameters in terms of the correlation functions and via the maximum-likelihood method. The precision is tested in the whole phase space and, when close to the coexistence line, the algorithm is used together with a clustering method to take care of the underlying possible ambiguity of the inversion.
