description: Studies of nearby galaxies reveal that roughly half of their low mass X-ray binary (LMXB) populations are associated with globular clusters (GCs). We have established that the LMXB hosting frequency is correlated to various GC properties such as mass and metallicity. While the X-ray luminosities of a few of the brightest LMXBs in GCs are consistent with the accreting object being a black hole (BH), the only definitive way to distinguish between a black hole and multiple superposed sources in a GC is to detect variability. We have discovered just such a variable 4x10^39 erg/s black hole X-ray binary in a low metallicity globular cluster in the halo of NGC 4472. The change in the X-ray spectrum between the bright and faint epochs suggests that the luminosity variation is due to eclipsing by a warped accretion disk. The optical spectrum of this source also reveals strong, broad, [O III] lambda 5007 and [O III] lambda 4959 emission. An analysis of the X-ray spectrum suggests that the [O III] lines are produced by the photoionization of a wind driven by a stellar mass black hole accreting mass at or above its Eddington luminosity. As it is dynamically implausible to form an accreting stellar mass BH system in a GC with an intermediate mass BH it appears that this massive globular cluster does not harbor an intermediate mass BH. The inferred mass of this BH falls well below the extrapolation of the well known M_BH-sigma and M_BH-M_Stellar relations to this GC. Therefore our analysis suggests that not all old, metal poor stellar systems form black holes consistent with these relations, which have been established for much more massive stellar systems.

description: Given the worldwide implications of overfishing and its ensuing ecological
 consequences, the central question this study seeks to address is to what
 extent are electronic traceability systems, endorsed by organisations like
 WWF, able to enhance the sustainability and governance of fisheries. In
 Peru, jumbo squid and mahi mahi fisheries play a pivotal role in the
 nation's socio-economic landscape, employing tens of thousands of
 people. Despite their immense importance, significant gaps exist in the
 sustainability and governance of these fisheries, exacerbated by limited
 data on annual catches and the number of operational vessels. Addressing
 these challenges would not only ensure the fisheries' prosperity but
 would also support sustainable marine resource management. Employing a
 realist evaluation approach within a case study framework, this research
 delves into the developmental journey of the Peruvian fisheries’
 traceability system. It considers various stakeholder perspectives,
 encompassing artisanal fishers, industry players, governmental officials,
 and environmental non-governmental organisation (ENGO) representatives,
 and investigates the role of ENGOs and government institutions in the
 traceability process. Findings suggest that such systems can significantly
 strengthen governance arrangements, potentially leading to a marked
 improvement in sustainability practices. However, technological
 adaptability challenges emerge as barriers, impacting the uptake of such
 systems within the fishing community. While electronic traceability
 systems appear to offer a promising solution for Peru's fisheries,
 its success is contingent upon addressing various inherent challenges,
 some being technological, with most others socioeconomic. This study
 posits that with appropriate adjustments, other global and national
 fisheries might also derive benefits from similar interventions.

description: We use the leading singularity technique to determine the planar three-loop five-particle amplitude in N=4 super Yang-Mills in terms of a simple basis of integrals. We analytically compute the integral coefficients for both the parity-even and the parity-odd parts of the amplitude. The parity-even part involves only dual conformally invariant integrals. Using the method of obstructions we numerically evaluate two previously unfixed coefficients which appear in the three-loop BDS ansatz.

description: Part of a collection of correspondence from Kathleen Raine to Robin Skelton. Skelton was a British poet, academic, anthologist, and practicing Wiccan. He taught at Manchester University before emigrating to Canada in 1963, where he taught creative writing at the University of Victoria and started the literary magazine The Malahat Review. Also included are some letters to Skelton’s wife Sylvia, and his daughters. Spanning close to forty-five years, the correspondence discusses poetry, writing, and philosophy; particularly Platonism and Neoplatonism. Raine often refers to the writings of William Blake and W. B. Yeats. Many letters also mention contemporary literary figures at the time including: Herbert Read, Peter Russell, Liam Miller, and Thurairajah Tambimuttu. In this letter, Raine writes extensively about her current book on William Blake.

description: We present the KMOS Galaxy Evolution Survey (KGES), a $K$-band Multi-Object Spectrograph (KMOS) study of the H$α$ and [NII] emission from 288 $K$ band-selected galaxies at $1.2 \lesssim z \lesssim 1.8$, with stellar masses in the range $\log_{10}(M_{*}/\rm{M}_{\odot})\approx$9-11.5. In this paper, we describe the survey design, present the sample, and discuss the key properties of the KGES galaxies. We combine KGES with appropriately matched samples at lower redshifts from the KMOS Redshift One Spectroscopic Survey (KROSS) and the SAMI Galaxy Survey. Accounting for the effects of sample selection, data quality, and analysis techniques between surveys, we examine the kinematic characteristics and angular momentum content of star-forming galaxies at $z\approx1.5$, $\approx1$ and $\approx0$. We find that stellar mass, rather than redshift, most strongly correlates with the disc fraction amongst star-forming galaxies at $z \lesssim 1.5$, observing only a modest increase in the prevalence of discs between $z\approx1.5$ and $z\approx0.04$ at fixed stellar mass. Furthermore, typical star-forming galaxies follow the same median relation between specific angular momentum and stellar mass, regardless of their redshift, with the normalisation of the relation depending more strongly on how disc-like a galaxy's kinematics are. This suggests that massive star-forming discs form in a very similar manner across the $\approx$ 10 Gyr encompassed by our study and that the inferred link between the angular momentum of galaxies and their haloes does not change significantly across the stellar mass and redshift ranges probed in this work.

description: Graph Neural Networks (GNNs) have been widely used to learn representations on graphs and tackle many real-world problems from a wide range of domains. In this paper we propose wsGAT, an extension of the Graph Attention Network (GAT) layers, meant to address the lack of GNNs that can handle graphs with signed and weighted links, which are ubiquitous, for instance, in trust and correlation networks. We first evaluate the performance of our proposal by comparing against GCNII in the weighed link prediction task, and against SGCN in the link sign prediction task. After that, we combine the two tasks and show their performance on predicting the signed weight of links, and their existence. Our results on real-world networks show that models with wsGAT layers outperform the ones with GCNII and SGCN layers, and that there is no loss in performance when signed weights are predicted.
Politicising curatorial discourse: performativity and the radical imaginary in the curated encounter

description: This practice-based Ph.D. addresses the complex relationship between politicised curating and performativity in contemporary curatorial practice. It chooses the representation of activism as a critical perspective within the field curatorial research, using this as a way into the notion of curatorial practice as a politicised process. With a focus on the social dimension of curatorial encounters, it teases out the rapport between the individual and the collective, arguing that the notion of performativity frames politicised curating. By unpacking the notions of politicised practice and tackling concepts of publicness in art and political theory, the thesis finds the context of radical . Through the analysis of the curatorial projects Collateral Effects - Beyond a Radical Milan (2013/2014) and Curating as a Form of Assembly (2015), which apply notions of the assembly through performative curating, this practice based doctoral research contributes to the field of curatorial studies and political theory by questioning whether performative curating can be framed as a politicised process, and whether the radical imaginary can be considered as a politicised process of embodied political imagination, enacted through the experience of performatively curated encounters. The concepts of the radical imaginary and radical imagination are two of the most important contributions to political theory of the Greek-French philosopher Cornelius Castoriadis. Castoriadis hypothesises that the process of autonomy involves both the human psyche and political discourses of change. Alongside the writings of Castoriadis, the critical production of American feminist philosopher Judith Butler, inform this research. These authors focus attention on everyday life within capitalism and envision this micro-dimension as the possible grounding for radical social change. Bringing together the performative dimension of art and politics, this practice based doctoral research builds on renewed interest in the work of Castoriadis. Whilst acknowledging the importance of his ideas within the field of art and politics, it claims that it is through the performative dimension that his writings are key to the further development of politicised practice.

description: Despite major advancements in nonlinear programming (NLP) and convex relaxations, most system operators around the world still predominantly use some form of linear programming (LP) approximation of the AC power flow equations. This is largely due to LP technology's superior reliability and computational efficiency, especially in real-time market applications, security-constrained applications, and extensions involving integer variables, in addition to its ability to readily generate locational marginal prices (LMP) for market applications. In the aim of leveraging the advantages of LP while retaining the accuracy of NLP interior-point methods (IPMs), this paper proposes a sequential linear programming (SLP) approach consisting of a sequence of carefully constructed supporting hyperplanes and halfspaces. The algorithm is numerically demonstrated to converge on 138 test cases with up the 3375 buses to feasible high-quality solutions (i) without AC feasibility restoration (i.e., using LP solvers exclusively), (ii) in computation times generally within the same order of magnitude as those from a state-of-the-art NLP solver, and (iii) with robustness against the choice of starting point. In particular, the (relative) optimality gaps and the mean constraint violations are on average around 1e-3% and 1e-7, respectively, under a single parameter setting for all the 138 test cases. To the best of our knowledge, the proposed SLP approach is the first to use LP exclusively to reach feasible and high-quality solutions to the nonconvex AC OPF in a reliable way, which paves the way for system and market operators to keep using their LP solvers but now with the ability to accurately capture transmission losses, price reactive power (Q-LMP), and obtain more accurate LMP.

description: Excerpts from the report Introduction: As a result of depressed prices to growers in recent years, cranberry marketing organizations have been searching for new or improved products that would increase total sales and bring about more satisfactory returns to growers. Production of frozen cranberries for sale when fresh berries are out of season has been considered as a means of extending the marketing period. The freezing process is relatively simple, and frozen berries experience little loss in weight and volume. Fresh cranberries, on the other hand, shrink as much as 33 percent when stored for extended periods of time and are subject to spoilage and loss of quality. An important factor in deciding whether or not to market cranberries in frozen form is consumer reaction to the product. Since no information on this point was available, the Department of Agriculture undertook research intended to provide the industry with data on consumer acceptance of frozen cranberries . The purpose of this report is to describe the reactions to frozen berries of homemakers who participated in the study. It should be of interest to producers, processors, wholesalers, retailers, and others concerned with the marketing of cranberries.

description: A rudimentary calculation is employed to evaluate the possible effects of beta- decays of excited-state nuclei on the astrophysical r-process. Single-particle levels calculated with the FRDM are adapted to the calculation of beta-decay rates of these excited-state nuclei. Quantum numbers are determined based on proximity to Nilson model levels. The resulting rates are used in an r-process network calculation in which a supernova hot-bubble model is coupled to an extensive network calculation including all nuclei between the valley of stability and the neutron drip line and with masses A<284. Beta-decay rates are included as functional forms of the environmental temperature. While the decay rate model used is simple and phenomenological, it is consistent across all 3700 nuclei involved in the r-process network calculation. This represents an approximate first estimate to gauge the possible effects of excited-state beta-decays on r-process freeze-out abundances.

description: We study the small deviation problem $\log\mathbb{P}(\sup_{t\in[0,1]}|X_t|\leq\varepsilon)$, as $\varepsilon\to0$, for general Lévy processes $X$. The techniques enable us to determine the asymptotic rate for general real-valued Lévy processes, which we demonstrate with many examples. As a particular consequence, we show that a Lévy process with nonvanishing Gaussian component has the same (strong) asymptotic small deviation rate as the corresponding Brownian motion.

description: We investigate the energy dependence of Jovian electron residence times, which allows for a deeper understanding of adiabatic energy changes that occur during charged particle transport, as well as of their significance for simulation approaches. Thereby we seek to further validate an improved approach to estimate residence times numerically by investigating the implications on previous analytical approaches, and possible effects detectable by spacecraft data. Utilizing a propagation model based on a Stochastic Differential Equation (SDE) solver written in CUDA, residence times for Jovian electrons are calculated over the whole energy range dominated by the Jovian electron source spectrum. We analyse the interdependences both with the magnetic connection between observer and the source as well as between the the distribution of the exit (simulation) times and the resulting residence times. We point out a linear relation between the residence time for different kinetic energies and the longitudinal shift of the 13 month periodicity typically observed for Jovian electrons and discuss the applicability of these findings to data. Furthermore, we utilize our finding that the simulated residence times are approximately linearly related to the energy loss for Jovian and Galactic electrons, and develop an improved analytical estimation in agreement with the numerical residence time and the longitudinal shift observed by measurements.

description: In this paper, the compact gas-kinetic scheme for compressible flow is extended to hybrid unstructured mesh. Based on both cell-averaged flow variables and their gradients updated from time accurate gas evolution model at cell interfaces, a compact third-order least-square-constrained reconstruction can be obtained on unstructured mesh and a multi-resolution WENO reconstruction is adopted in case of discontinuous solutions. Moreover, a compression factor for the cell-averaged gradients is proposed to take into account the possible discontinuity in flow variables at cell interface, which significantly improves the robustness of the compact scheme for high-speed flow computation on irregular mesh and preserves the accuracy. Numerical tests from incompressible to hypersonic flow are presented to demonstrate the broad applicability of the gradient-compression-based high-order compact scheme.

description: Rapid progress in cooling and trapping of molecules has enabled first experiments on high resolution spectroscopy of trapped diatomic molecules, promising unprecedented precision. Extending this work to polyatomic molecules provides unique opportunities due to more complex geometries and additional internal degrees of freedom. Here, this is achieved by combining a homogeneous-field microstructured electric trap, rotational transitions with minimal Stark broadening at a 'magic' offset electric field, and optoelectrical Sisyphus cooling of molecules to the low millikelvin temperature regime. We thereby reduce Stark broadening on the $J=5\leftarrow4$ ($K=3$) transition of formaldehyde at $364\,$GHz to well below $1\,$kHz, observe Doppler-limited linewidths down to $3.8\,$kHz, and determine the 'magic'-field line position with an uncertainty below $100\,$Hz. Our approach opens a multitude of possibilities for investigating diverse polyatomic molecule species.

description: Die in den Strukturen der sozialen Ordnung angelegte Geschlechterungleichheit wird im Falle einer Familiengründung verstärkt wirksam, da der aufgeworfene Widerspruch zwischen familialer Lebensführung in der heutigen Erwerbsgesellschaft auf der einen Seite und der ökonomischen Existenzsicherung auf der anderen Seite von den Akteuren in ihrer alltäglichen Praxis aufgelöst werden muss. Liebe spielt dabei eine besondere Rolle, und zwar nicht nur als Liebe zwischen Menschen, sondern vor allem als Liebe zum Schicksal, als amor fati. Nach Bourdieu ist dies die „körperliche Neigung, eine Identität zu verwirklichen“ (Bourdieu 2005: 91). Bei dieser Inkorporierung des Sozialen handelt es sich gleichzeitig um Inkorporation von Herrschaft (im Sinne einer sozialen Ordnung, wie der Geschlechterordnung). Verkörperte Geschlechterkonstruktionen sind tief verankerte Überzeugungen der Akteurinnen und Akteure, die offen sind für die Wirkungen symbolischer Gewalt. Sie knüpfen an die noch immer durch Organisationsformen von Arbeit unterstützte und in den Strukturen gesellschaftlicher Institutionen enthaltene Geschlechterdichotomien an, auch wenn das Paar nach Gleichheit strebt.

description: The transport properties of nematic aerogels, which consist of highly oriented Al$_2$O$_3\cdot$SiO$_2$ nanofibers coated with a graphene shell with a large number of defects, are studied. The temperature dependences of the electrical resistivity in the range of 9-40K strictly follow the formula derived to describe the variable range hopping (VRH) conductivity, in which exponent $α$ changes from 0.4 to 0.9 when the number of layers in the graphene shell decreases from 4-6 to 1-2. The dependence of $α$ on the shell thickness can be explained by a simultaneous change in the dimensionality of hopping transport and the character of the energy dependence of the density of localized states near the Fermi level. The fact that $α$ approaches unity at the minimum graphene shell thickness indicates a gradual transition from VRH transport to nearest neighbor hopping (NNH) transport. The magnetoresistance measured at T = 4.2 K is negative, increases significantly with decreasing graphene shell thickness, and is approximated by a formula for the case of weak localization with a good accuracy. The phase coherence lengths are in a reasonable relation with the graphene grain sizes. The conducting aerogels under study complement the well-known set of materials that exhibit hopping electron transport at low temperatures, which is characteristic of media with strong carrier localization, and also a negative magnetoresistance, which usually manifests itself under weak localization conditions.

description: Algorithms implementing populations of agents which interact with one another and sense their environment may exhibit emergent behavior such as self-organization and swarm intelligence. Here a swarm system, called Databionic swarm (DBS), is introduced which is able to adapt itself to structures of high-dimensional data characterized by distance and/or density-based structures in the data space. By exploiting the interrelations of swarm intelligence, self-organization and emergence, DBS serves as an alternative approach to the optimization of a global objective function in the task of clustering. The swarm omits the usage of a global objective function and is parameter-free because it searches for the Nash equilibrium during its annealing process. To our knowledge, DBS is the first swarm combining these approaches. Its clustering can outperform common clustering methods such as K-means, PAM, single linkage, spectral clustering, model-based clustering, and Ward, if no prior knowledge about the data is available. A central problem in clustering is the correct estimation of the number of clusters. This is addressed by a DBS visualization called topographic map which allows assessing the number of clusters. It is known that all clustering algorithms construct clusters, irrespective of the data set contains clusters or not. In contrast to most other clustering algorithms, the topographic map identifies, that clustering of the data is meaningless if the data contains no (natural) clusters. The performance of DBS is demonstrated on a set of benchmark data, which are constructed to pose difficult clustering problems and in two real-world applications.

We discuss separately decays of natural parity states: two $0^+$, one $1^{-}$, three $2^+$, one $3^-$, two $4^+$, one $6^+$, and one of each of unnatural parity, $1^{+}$, $2^-$, $3^+$, $4^-$. The lowest natural parity state of each $J^π$ decays predominantly sequentially via the $^{8}$Be ground state whereas other states including unnatural parity states predominantly decay directly to the continuum. We present Dalitz plots and systematic detailed momentum correlations of the emerging $α$-particles.

description: The Controller Area Network (CAN) bus works as an important protocol in the real-time In-Vehicle Network (IVN) systems for its simple, suitable, and robust architecture. The risk of IVN devices has still been insecure and vulnerable due to the complex data-intensive architectures which greatly increase the accessibility to unauthorized networks and the possibility of various types of cyberattacks. Therefore, the detection of cyberattacks in IVN devices has become a growing interest. With the rapid development of IVNs and evolving threat types, the traditional machine learning-based IDS has to update to cope with the security requirements of the current environment. Nowadays, the progression of deep learning, deep transfer learning, and its impactful outcome in several areas has guided as an effective solution for network intrusion detection. This manuscript proposes a deep transfer learning-based IDS model for IVN along with improved performance in comparison to several other existing models. The unique contributions include effective attribute selection which is best suited to identify malicious CAN messages and accurately detect the normal and abnormal activities, designing a deep transfer learning-based LeNet model, and evaluating considering real-world data. To this end, an extensive experimental performance evaluation has been conducted. The architecture along with empirical analyses shows that the proposed IDS greatly improves the detection accuracy over the mainstream machine learning, deep learning, and benchmark deep transfer learning models and has demonstrated better performance for real-time IVN security.

description: We introduce an overcomplete highest weight state basis as a calculational tool for the description of the isotropic spin-1 chain with bilinear exchange coupling J1 and biquadratic coupling J2. The ground state can be expressed exactly at the three special points in the phase diagram where the Hamiltonian corresponds to a sum of nearest neighbor total spin projection operators (J1=0>J2, J1=-J2<0, and J1=-J2/3<0). In particular, at the phase transition point J1=-J2<0 it is possible to exactly compute the ground states, excited states, expectation values, and correlation functions by using the new total spin basis.

Two dimensional relaxation of gravitational instability in porous media

description: Due to its central interest in Carbon Capture and Storage (CCS), gravitational instability has been extensively studied numerically, primarily in (2D) bi-dimensional configuration. Likewise, several experimental studies have been performed in model 2D geometries (HeleShaw cell) where dispersive nature of the medium was overlooked. We propose here a preliminary study that aims at accounting for the pore-scale effects such as mixing and dispersion. We first study the behaviour of a solutal plume generated in a Hele-Shaw cell from an extended source. Doing so, we introduce a new length scale in the system, a first step towards more complex multi-scale geometries. The CO2-concentration is measured by using a pH-sensitive dye and the velocity field is measured by utilizing standard particle image velocimetry (PIV). Concentration and velocity fields are scrutinized over one order of magnitude in Rayleigh number (Ra) and for two different values of the Darcy number (Da). A semi-empirical relationship linking Nusselt to the Darcy and Rayleigh numbers number is proposed. Two regimes, Ra Da < 1 and Ra Da > 1, are observed for which the scaling laws for velocity and concentration are presented. While the concentration field measurements are marred by a large uncertainty due to the logarithmic nature of the pH-concentration relationship, the experimental data obtained from the PIV measurements show a good agreement with the numerical results. We next address more complex (multiscale) 2D porous geometries where pore-scale effects are explicitly taken into account. To do so, we study gravitational instability in bespoke 2D micromodels, the core of which is made from Norland optics 63 or NOA63, a UV curable photo resin which is impermeable to gases. We describe a soft-lithography repeatable protocol suitable for the manufacturing of symmetric regular patterns of cylindrical pillars sandwiched between two vertical plane walls, with pillars radii ranging from R = 200 to 400 µm, and edge-to-edge distances (between pillars) ranging from R to 4R. We present an empirical correlation bridging the permeability of the system with the porosity and specific surface area of the 2D micromodels. The wavenumber of gravitational instability induced by the dissolution of carbon dioxide is found to be larger than the theoretical value obtained for Hele-Shaw cells (of equivalent permeability) possibly due to wavelength locking by the porous pattern. The time profile of the mass flux indicates a clear diffusive regime of dissolution despite the presence of a convective dissolution fingering pattern.

description: Attempts to connect string theory with astrophysical observation are hampered by a jargon barrier, where an intimidating profusion of orientifolds, Kahler potentials, etc. dissuades cosmologists from attempting to work out the astrophysical observables of specific string theory solutions from the recent literature. We attempt to help bridge this gap by giving a pedagogical exposition with detailed examples, aimed at astrophysicists and high energy theorists alike, of how to compute predictions for familiar cosmological parameters when starting with a 10-dimensional string theory action. This is done by investigating inflation in string theory, since inflation is the dominant paradigm for how early universe physics determines cosmological parameters. We analyze three explicit string models from the recent literature, each containing an infinite number of "vacuum" solutions. Our numerical investigation of some natural candidate inflatons, the so-called "moduli fields", fails to find inflation. We also find in the simplest models that, after suitable field redefinitions, vast numbers of these vacua differ only in an overall constant multiplying the effective inflaton potential, a difference which affects neither the potential's shape nor its ability to support slow-roll inflation. This illustrates that even having an infinite number of vacua does not guarantee having inflating ones. This may be an artifact of the simplicity of the models that we study. Instead, more complicated string theory models appear to be required, suggesting that explicitly identifying the inflating subset of the string landscape will be challenging.

description: Publicações independentes existem há muito tempo, como veículo para dar voz aqueles que procuram explorar diferentes temas, formatos e experimentações gráficas. Já faz alguns anos que esse movimento tem tomado novas formas no Brasil, a partir das feiras gráficas, financiamentos coletivos ou publicações online. A partir de questionários online e entrevistas com editoras independentes e publicadores, começamos a analisar mais profundamente as relações presentes nesse meio, suas práticas tanto de publicação como de organização editorial. Assim, refletimos sobre como a figura do editor-publicador se insere neste contexto de produção editorial independente brasileiro, como essas práticas contribuem para o ecossistema editorial do país e para uma produção mais diversa. E as diferentes construções de sentido atreladas à figura do editor e do publicador, que são cada vez mais utilizadas de formas diferentes no meio independente, com uma possível abnegação ou modificação de como este editor é enxergado.

description: Nowadays, Software Process Improvement popularly known as SPI has been able to receive an immense concern in the continuous process to purify software quality. Several Agile methodologies previously have worked with Extreme programming (XP). Before improving the process, defect prevention (DP) is inevitable. In addition, DP largely depends on defect detection either found earlier in the design and implementation stages or held in the testing phases. However, testing maturity model integration (TMMI) has a crucial aspect in DP as well as process improvement of the software. In particular, when software gets validated by being tested and fixed the defects up, it achieves the maximum capability maturity model integration (CMMI) aiming the process improvement. Here, the article has proposed an improved defect detection and prevention model to enhance the software process following the approach of XP. Besides, as a unique contribution, we have united the capability and testing model integration to ensure better SPI.

description: In this paper spatial correlations of parallel edge dislocations are studied. After closing a hierarchy of equations for the many-particle density functions by the Kirkwood superposition approximation, we derive evolution equations for the correlation functions. It is found that these resulting equations and those governing the evolution of density fields of total as well as geometrically necessary dislocations around a single edge dislocation are formally the same. The second case corresponds to the already described phenomenon of Debye screening of an individual dislocation. This equivalence of the correlation functions and screened densities is demonstrated also by discrete dislocation dynamics simulation results, which confirm the physical correctness of the applied Kirkwood superposition approximation. Relation of this finding and the linear response theory in thermal systems is also discussed.
