description: The phonon damping model (PDM) is extended to include the effect of angular momentum at finite temperature. The model is applied to the study of damping of giant dipole resonance (GDR) in hot and noncollectively rotating spherical nuclei. The numerical results obtained for Mo88 and Sn106 show that the GDR width increases with both temperature T and angular momentum M. At T > 4 MeV and M<= 60 hbar the increase in the GDR width slows down for Sn106, whereas at M<= 80 hbar the GDR widths in both nuclei nearly saturate. By adopting the nuclear shear viscosity extracted from fission data at T= 0, it is shown that the maximal value of the angular momentum for Mo88 and Sn106 should be around 46 and 55 hbar, respectively, so that the universal conjecture for the lower bound of the specific shear viscosity for all fluids is not violated up to T= 5 MeV.

description: This thesis applies a real options approach to the valuation of undeveloped natural gas reserves in Alberta. The real options approach is recommended as an alternative to standard net present value analysis in situations where the investment is irreversible, future cash flows are uncertain, and the firm has operating flexibility to delay investment. Cash flow uncertainty is mcxlelled solely as a function of natural gas price volatility. Standard net present value analysis has several disadvantages in making risky investment decisions. Most prominent is its inability to evaluate the potential benefits from delaying an irreversible investment, thus resulting in non-optimal decision rules. This thesis attempts to econometrically test whether real options theory or discounted cash flow analysis is better able to explain investment behaviour from a statistical point of view.

description: Over the past five years, graphics processing units (GPUs) have had a transformational effect on numerical lattice quantum chromodynamics (LQCD) calculations in nuclear and particle physics. While GPUs have been applied with great success to the post-Monte Carlo "analysis" phase which accounts for a substantial fraction of the workload in a typical LQCD calculation, the initial Monte Carlo "gauge field generation" phase requires capability-level supercomputing, corresponding to O(100) GPUs or more. Such strong scaling has not been previously achieved. In this contribution, we demonstrate that using a multi-dimensional parallelization strategy and a domain-decomposed preconditioner allows us to scale into this regime. We present results for two popular discretizations of the Dirac operator, Wilson-clover and improved staggered, employing up to 256 GPUs on the Edge cluster at Lawrence Livermore National Laboratory.

description: In this paper, an extension of raptor codes is introduced which keeps all the desirable properties of raptor codes, including the linear complexity of encoding and decoding per information bit, unchanged. The new design, however, improves the performance in terms of the reception rate. Our simulations show a 10% reduction in the needed overhead at the benchmark block length of 64,520 bits and with the same complexity per information bit.

description: To find X-ray bursts from sources within the field of view of the IBIS/INTEGRAL telescope, we have analysed all the archival data of the telescope available at the time of writing the paper (the observations from January 2003 to April 2009). We have detected 834 hard (15-25 keV) X-ray bursts, 239 of which were simultaneously recorded by the JEM-X/INTEGRAL telescope in the standard X-ray energy range. More than 70% of all bursts (587 events) have been recorded from the well-known X-ray burster GX 354-0. We have found upper limits on the distances to their sources by assuming that the Eddington luminosity limit was reached at the brightness maximum of the brightest bursts.

description: The presence of hot gaseous coronae in the dark matter halos of massive spiral galaxies is a fundamental prediction of all structure formation models. Yet these coronae remained unexplored for several decades, thereby posing a serious challenge to observers and theorists. Although several X-ray coronae have been detected around nearby massive spiral galaxies in the past few years, we still lack a comprehensive picture. X-ray Surveyor will provide the much needed breakthrough. Specifically, X-ray Surveyor will characterize the hot coronae in unprecedented details, explore their evolution as a function of redshift, which in turn will constrain the physical processes that play an essential role in galaxy formation from the early Universe to the present epoch.

description: At the Protections 2018 conference, the WireWall wave overtopping research project was introduced. WireWall uses recent advances in high frequency capacitance wire technology that can measure overtopping data. Wave overtopping has now been measured in the laboratory and in the field using the WireWall system. Here we provide an update on the validation of the system in flume tests and results from the first field measurement campaign.
Before deployment in the field, an extensive set of tests were carried out in one of the 2D wave flumes at HR Wallingford. These tests simulated known wave conditions from a buoy near the field measurement site, and a representation of the sea wall at the site. The structure (shown in Figure 1) underwent extensive testing and was used to validate the WireWall rig. Using traditional methods of assessing wave overtopping in the flume, the WireWall measurements were directly validated against the known volumes collected in the overtopping tanks.
The WireWall field system was deployed at Crosby, Liverpool during the winter of 2018/19, where waves regularly overtop the sea wall. Comparison between the WireWall measurements and the BayonetGPE predictions for one of the Crosby deployments shows good agreement, with the predictions and the WireWall measurements being within the uncertainties estimated for the BayonetGPE predictions.
Hidden Multiple-spin Interactions as an Origin of Spin Scalar Chiral Order in Frustrated Kondo Lattice Models

description: We reveal the significance of kinetic-driven multiple-spin interactions hidden in geometrically-frustrated Kondo lattice models. Carefully examining the perturbation in terms of the spin-charge coupling up to the fourth order, we find that a positive biquadratic interaction is critically enhanced and plays a crucial role on stabilizing a spin scalar chiral order near 1/4 filling in a triangular lattice case. This is a generalized Kohn anomaly, appearing only when the second-order perturbation is inefficient because of the degeneracy under frustration. The mechanism is potentially common to frustrated spin-charge coupled systems, leading to emergence of unusual magnetic orders.

Queen Esther in Venice: Art and Drama

Publisher: name: Skenè. Journal of Theatre and Drama Studies
Year: 2023

description: This article looks at the representations of Queen Esther in the Venetian visual tradition from the fourteenth through the seventeenth century by studying contemporaneous art in conjunction with the play by Leon Modena. Venice witnessed the emergence of Queen Esther as a popular subject in Renaissance culture. Artists introduced Esther and her narrative, offering multilayered interpretations of this biblical queen. This article explores the increasing frequency of allusions to Queen Esther in Venetian culture and proposes the reasons for that interest. Esther was seen as an ideal bride, as a court lady, as an oriental figure offering an opportunity for the authors and artists to express the attraction of the East. She was also seen as a prototype of the Virgin Mary, and as a Jewish maiden reflecting issues of toleration and assimilation of the Jews in Venice. Most intriguing is the question of how Venice, a city infamous for its ghetto and anti-Semitic practices, welcomed the Esther cycle of the artist Paolo Veronese in the church of San Sebastiano (1556) as well as the numerous representations of Esther by the celebrated Mannerist artist Tintoretto (1546-7). The article specifically explores the connections between works of art and the religious drama of Leon Modena. Keywords: Venice; Esther; art; Leon Modena; Veronese; Tintoretto; Pascarol Scrolls

description: The approval of the Technical Safety Standards for dams and reservoirs in Spain in 2021 increased the hydrological safety requirements, being necessary to check if measures have to be implemented in dams designed according to the prior standards. Some of these dams have scarce instrumentation and lack of hydrometeorological data. This work proposes a simple but sounded fully-stochastic methodology for assessing the hydrological safety of dams within this situation, potentially applicable outside academia. The methodology has been applied to a case study based on a real dam, and compared the results obtained to those of the standard deterministic procedure. We have found that the fully-stochastic methodology leads to higher maximum reservoir levels for the same return period, leading therefore to more conservative results for the case study. On this regard, potential flaws have been detected regarding the hypothesis of the standard deterministic procedure, discussed and solved by the proposed fully-stochastic methodology, which accounts for the stochastic nature of variables such as rainfall temporal patterns and antecedent runoff conditions. Moreover, the proposed methodology can be adapted for accounting for operational variables such as the initial reservoir level when the flood event occurs, providing results that resemble more to the reality of nature and the reality of dam-reservoir systems.

Hydraulic transmissivity and heat exchange efficiency of open fractures: a model based on lowpass filtered apertures

Year: 2011

description: Natural open joints in rocks commonly present multi-scale self-affine apertures. This geometrical complexity affects fluid transport and heat exchange between the flow- ing fluid and the surrounding rock. In particular, long range correlations of self-affine apertures induce strong channeling of the flow which influences both mass and heat advection. A key question is to find a geometrical model of the complex aperture that describes at best the macroscopic properties (hydraulic conductivity, heat exchange) with the smallest number of parameters. Solving numerically the Stokes and heat equa- tions with a lubrication approximation, we show that a low pass filtering of the aperture geometry provides efficient estimates of the effective hydraulic and thermal properties (apertures). A detailed study of the influence of the bandwidth of the lowpass filtering on these transport properties is also performed. For instance, keeping the information of amplitude only of the largest Fourier length scales allows us to reach already an accuracy of 9% on the hydraulic and the thermal apertures.

description: The higher gauge field in 11-dimensional supergravity -- the C-field -- is constrained by quantum effects to be a cocycle in some twisted version of differential cohomology. We argue that it should indeed be a cocycle in a certain twisted nonabelian differential cohomology. We give a simple and natural characterization of the full smooth moduli 3-stack of configurations of the C-field, the gravitational field/background, and the (auxiliary) E8-field. We show that the truncation of this moduli 3-stack to a bare 1-groupoid of field configurations reproduces the differential integral Wu structures that Hopkins-Singer had shown to formalize Witten's argument on the nature of the C-field. We give a similarly simple and natural characterization of the moduli 2-stack of boundary C-field configurations and show that it is equivalent to the moduli 2-stack of anomaly free heterotic supergravity field configurations. Finally we show how to naturally encode the Horava-Witten boundary condition on the level of moduli 3-stacks, and refine it from a condition on 3-forms to a condition on the corresponding full differential cocycles.

description: Timing pulses of pulsars has proved to be a most powerful technique useful to a host of research areas in astronomy and physics. Importantly, the precision of this timing is not only affected by radiometer noise, but also by intrinsic pulse shape changes, interstellar medium (ISM) evolution, instrumental distortions, etc. In this paper we review the known causes of pulse shape variations and assess their effect on the precision and accuracy of a single measurement of pulse arrival time with current instrumentation. Throughout this analysis we use the brightest and most precisely timed millisecond pulsar (MSP), PSR J0437-4715, as a case study, and develop a set of diagnostic tools to evaluate profile stability in timing observations. We conclude that most causes of distortion can be either corrected by state-of-the-art techniques or taken into account in the estimation of time-of-arrival (TOA) uncertainties. The advent of a new generation of radio telescopes (e.g. the Square Kilometre Array, SKA), and their increase in collecting area has sparked speculation about the timing precision achievable through increases in gain. Based on our analysis of current data, we predict that for normal-brightness MSPs a TOA precision of between 80 and 230 ns can be achieved at 1.4 GHz with 10-minute integrations by the SKA. The actual rms timing residuals for each pulsar will be approximately at the same level only if all the other influences on timing precision (e.g. ISM, spin noise) are either corrected, modelled, or negligible.

The Feast as Performance: Esther in Sixteenth-Century German Plays
Creators: name: Dietl, Cora
Publisher: name: Skenè. Journal of Theatre and Drama Studies
Year: 2023

description: The Book of Esther was extremely popular as a dramatic subject in the German speaking countries in sixteenth and early seventeenth century, especially in Protestant regions. The several feasts mentioned in the biblical book gave the opportunity to draw connecting links between festive contexts of the performances of these plays, and to consider and display the effect of performative presentations. The chapter chooses three out of twenty preserved texts (by Valten Voith, Hans Sachs, and Jos Murer) and analyzes the significance of the feast and banquet scenes in these plays. These scenes reveal to be essential for the political, religious, and moral interpretation of the biblical book in each play.

Esther in the Drama of the Early Modern Low Countries

Year: 2023

description: Even though topics from the Hebrew Bible abound in the sixteenth-century drama of the Low Countries written in the vernacular, the character of Esther does not appear on stage in the Dutch language before the start of the seventeenth century. Neo-Latin plays on Esther did, however, precede them. In this article I will concentrate on four plays, written by Dutch and Flemish dramatists. The first is a neo-Latin play: Tragoedia Esther sive Edissa, written in 1544 by Petrus Philicinus and printed in 1563. I will subsequently discuss three vernacular plays about Esther: an anonymous play entitled Hester en Assverus from the town of Hasselt, probably written before 1615; Nicolaas Fonteyn’s Esther, ofte ’t Beeldt der Ghehoorsaamheid from 1637; and Joris Berckmans’s “happy-ending tragedy” Edissa from 1649. In discussing these plays, I will focus on the way in which the character of Esther was portrayed. In Philicinus’s play Esther is depicted as a mediatrix between the Jewish people and the Persians, yet at the same time fully aware of the dangers she may inflict upon herself. The Hasselt play and the play by Berckmans demonstrate Esther’s loyalty towards Ahasuerus. These two plays contrast her sweet and obedient character to Vasthi’s less sympathetic attitude towards the king. Fonteyn also describes her as a loyal queen to Ahasuerus; her virtue is beyond any doubt. What is more, in all four plays Esther emphatically voices her trust in God.

description: The automated process chain of an unmanned production system is a distinct challenge in the technical state of the art. In particular, accurate and fast raw-part recognition is a current problem in small-batch production. This publication proposes a method for automatic optical raw-part detection to generate a digital blank shadow, which is applied for adapted CAD/CAM (computer-aided design/computer-aided manufacturing) planning. Thereby, a laser-triangulation sensor is integrated into the machine tool. For an automatic raw-part detection and a workpiece origin definition, a dedicated algorithm for creating a digital blank shadow is introduced. The algorithm generates adaptive scan paths, merges laser lines and machine axis data, filters interference signals, and identifies part edges and surfaces according to a point cloud. Furthermore, a dedicated software system is introduced to investigate the created approach. This method is integrated into a CAD/CAM system, with customized software libraries for communication with the CNC (computer numerical control) machine. The results of this study show that the applied method can identify the positions, dimensions, and shapes of different raw parts autonomously, with deviations less than 1 mm, in 2.5 min. Moreover, the measurement and process data can be transferred without errors to different hardware and software systems. It was found that the proposed approach can be applied for rough raw-part detection, and in combination with a touch probe for accurate detection.

Publisher: name: Utah State University
Year: 2022

description: Overtopping protection using roller-compacted concrete (RCC) overlays is a common improvement made to address hydrologic deficiencies at existing small- to medium-height embankment dams. Overlays allow floods to pass over the dam while preventing erosion of the original embankment. The United States has many examples of such projects on both private and public dams, including many associated with federal agencies of the Departments of the Interior and Agriculture. For one project modified with an overlay in 1993, deterioration of the RCC and poor bonding between lifts has caused concern for stability of the 0.3-m (1-ft) thick RCC lifts that cap the dam. Analytical studies from 2013 to the present have assessed potential failure modes during overtopping flow and have produced widely varying estimates of the probability of failure. To address this uncertainty, physical scale modeling in the Bureau of Reclamation Hydraulics Laboratory was used to evaluate crest cap failure modes for the conservative condition of unbonded RCC lifts. The testing defines the threshold conditions for failure, which will enable effective evaluation of risk for similar facilities in the future.

Cassandra as a False Chorus and Her Skeuê in Euripides’ Trojan Women
Creators: name: Kousoulini, Vasiliki
Publisher: name: Skenè. Journal of Theatre and Drama Studies
Year: 2023

description: Female characters and female choruses seem to have strong bonds in Euripides’ plays, there are instances in the Euripidean corpus in which a heroine cannot interact the way she wishes with the chorus. The chorus remains almost unresponsive, despite the heroine’s efforts to involve them in a kind of choral activity. Bierl, commenting on this phenomenon, has characterized one of these heroines as a false chorus leader. This essay examines Cassandra in The Trojan Women as a false chorus leader of hymaenaios, focusing on her skeuê. Cassandra attempts to involve a female chorus in the performance of a choral song. She distorts the usual choral form and urges others to join her deviant choreia. To mark her choral activity, this solo singer is equipped with objects that reveal her intentions. Parts of her costume reveal Cassandra’s identity to other characters, the female chorus, and the audience. This paperfocuses on the verbal descriptions of the parts of the skeuê of Cassandra and its functions and argues that her descriptions reveal the character’s role as a false chorus leader to the play’s internal and external audience.

title: Applying the Submerged Jet Erosion Test to Embankment Dam Breach Modeling
Creators: name: Wahl, Tony L.
name: Armstrong, Blake
Publisher: name: Utah State University
Year: 2022

description: The submerged jet erosion test (JET) is one of several methods available for quantifying erodibility of cohesive soils, a crucial input for modeling erosion and breach of embankment dams with models such as WinDAM, EMBREA (Morris 2011), and DL BREACH (Wu 2013; 2016a; 2016b). The JET was initially developed in the late 1980s as a relatively large-scale device with a 13-mm diameter nozzle creating an impinging jet that erodes a soil sample submerged in a 61-cm diameter tank. This first device was documented in an ASTM standard (D5852-1995), but the standard was withdrawn in 2016. In the last 15 to 20 years, smaller scale devices have become common, including one described as the “original JET” (6.4-mm nozzle operating within a 30.5-cm tank) (Hanson and Cook 2004) and the newer “mini-JET” (3 mm nozzle and 10-cm tank) (Al-Madhhachi et al. 2013b). New methods for analyzing the scour-vs.-time data obtained from the JET have also been proposed, some (Daly et al. 2013) based on the traditional linear excess stress equation describing the soil etachment process, and others (Al-Madhhachi et al. 2013a) based on nonlinear soil erosion models such as the mechanistic Wilson model (Wilson 1993a, 1993b). This paper provides an overview of JET history and development and then summarizes a recent study (Wahl 2021) comparing JET data analysis methods. Fifty-two JET experiments on four different soil types (lean clay, silty clay, clayey sand, and silty sand) were analyzed by nine different methods. The results give indications of the practical value of linear vs. nonlinear soil erosion models and the effectiveness of different curve-fitting methods for estimating erodibility parameters. Suggestions for the use of the JET in dam breach modeling are offered.

description: We use microscopic many-body theory to analyze the problem of itinerant ferromagnetism in a repulsive atomic Fermi gas of Hard Spheres. Using simple arguments, we show that the available theoretical predictions for the onset of the ferromagnetic transition predict a transition point at a density ($k_F a \sim 1$) that is too large to be compatible with the universal low-density expansion of the energy. We present new variational calculations for the hard-sphere Fermi gas, in the framework of Fermi hypperneted chain theory, that shift the transition to higher densities ($k_F a \sim 1.8$). Backflow correlations, which are mainly active in the unpolarized system, are essential for this shift.
title: Methodology for Calculating the Response of Porous Media for Evaluating Grass Response to Overtopping Loads

description: Grass covers offer a level of erosion protection against hydrodynamic loads induced by overtopping waves. The development of an accurate failure criterion for grass covers has been hampered by the lack of understanding of how grass fails. Methods have been developed to predict the hydrodynamic loads that act on the levee surface and consequently are transmitted to the porous grass cover and subsoil. However, it is unknown how these hydrodynamic surface loads on the soil are distributed amongst the pore water pressures and effective stresses, thereby offering a significant challenge for engineers to simulate the transmission of stresses into the porous grass cover. The analysis of the response of porous media is limited to either a fully drained analysis or an undrained analysis, neither of which offer sufficient insights into the time-dependent nature of the erosion resistance of grass covers. Little is thereby known on how grass responds to hydrodynamic loads and when it will fail. Here we outline the development of a new 2D continuum based model for porous media, which only requires the total stresses and shear stresses at the levee surface to be determined by the user. Based on this information the model determines how the distribution of the surface stresses into pore water pressures and effective stresses changes with time. The model is thereby able to resolve any time dependent and spatially distributed surface load. The solution to the model is constructed using separation of variables, which has led to analytical solutions of the constitutive equations for porous media and is consequently fast to run. The new modelling method would allow users to rapidly evaluate the erosion resistance of grass based on measurements of the turf layer characteristics. The development of the model opens up the possibility to perform fully time dependent calculations on the behavior of porous media.

description: We review the recursive solutions of the Seiberg--Witten map to all orders in $θ$ for gauge, matter and ghost fields. We also present the general structure of the homogeneous solutions of the defining equations. Moreover, we show that the contribution of the first order homogeneous solution to the second order can be written recursively similar to inhomogeneous solutions.

description: Characterisation and optimization of next-generation silicon solar cell concepts rely on an accurate knowledge of intrinsic charge carrier recombination in crystalline silicon. Reports of measured lifetimes exceeding the previous accepted parameterisation of intrinsic recombination indicate an overestimation of this recombination in certain injection regimes and hence the need for revision. In this work, twelve high-quality silicon sample sets covering a wide doping range are fabricated using state-of-the-art processing routes in order to permit an accurate assessment of intrinsic recombination based on wafer thickness variation. Special care is taken to mitigate extrinsic recombination due to bulk contamination or at the wafer surfaces. The combination of the high-quality samples with refined sample characterisation and lifetime measurements enables a much higher level of accuracy to be achieved compared to previous studies. We observe that reabsorption of luminescence photons inside the sample must be accounted for to achieve a precise description of radiative recombination. With this effect taken into account, we extract the lifetime limitation due to Auger recombination. We find that the extracted Auger recombination rate can accurately be parameterized using a physically motivated equation based on Coulomb-enhanced Auger recombination for all doping and injection conditions relevant for silicon-based photovoltaics. The improved accuracy of data description obtained with the model suggests that our new parameterisation is more consistent with the actual recombination process than previous models. Due to notable changes in Auger recombination predicted for moderate injection, we further revise the fundamental limiting power conversion efficiency for a single-junction crystalline silicon solar cell to 29.4%, which is within 0.1%abs compared to other recent assessments.

Self-invention, self-construction, self-reinvention: versions of self in the novels of Virginia Woolf

description: Bibliography: p. 93-94.
description: This thesis describes Virginia Woolf's representation of the self in three novels. In Mrs Dalloway, the self is a continuously-changing entity, confronting through particular memories former selves from the perspective of the present moment and the present self. Therefore the self is made up of a successive series of selves, progressively moving towards the present composite self. Woolf retains this view of the self in To the Lighthouse and The Waves, but alters the way in which she presents self-composition. In To the Lighthouse, the self is rendered as a painting. Woolf reinvents the self in The Waves by minimizing the narrator's voice so that the selfhoods of the six characters emerge entirely from their thought processes. Jacob's Room introduces this study, showing Woolf's initial work towards her fully-constructed vision of selfhood. Between the Acts is considered in the conclusion as a novel emphasizing that the Modernist self is fragmented to the point of disintegration.

title: First Application of Articulated Concrete Block Armoring with a Stabilized Stone Drainage Layer
Creators: name: Young, Jeremy R.
name: Nadeau, Jim
Publisher: name: Utah State University
Year: 2022

description: Results from recent hydraulic testing of Articulated Concrete Block (ACB) systems have shown variations in the level of the ACB surface is attributed to the movement of an unconfined stone drainage layer. This movement appears to be exacerbated by thicker drainage layers, higher overtopping depths, and longer test flumes. While the apparent movement did not constitute “threshold of performance” as currently defined by ASTM D7276 and D7277, there was a desire to mitigate movement of the stone drainage layer and maintain conservatism in ACB design and construction. This paper will review the findings of Nadeau and Wedin’s paper from Protections 2018, which proposed an ACB system with a stone drainage layer stabilized with geocell to increase ACB performance under steady state and hydraulic jump conditions. A similar ACB system was recently designed and constructed to provide overtopping protection at Hollymead Lake Dam located near Charlottesville, VA. The system was selected for added conservatism to address overtopping depths approaching 1.6m (5.4-ft), hydraulic jump conditions occurring on the downstream slope, and other complex flow conditions due to site geometry. The authors believe this to be the first application of its kind. Design and analysis of the Hollymead Lake Dam ACB will be summarized and include a comparison of the factor of safety with and without the geocell stabilized stone drainage layer. The project was completed in November 2019. Details from construction will also be presented.

description: As rates of urbanization and climatic change soar, decision-makers are increasingly challenged to provide innovative solutions that simultaneously address climate-change impacts and risks and inclusively ensure quality of life for urban residents. Cities have turned to nature-based solutions to help address these challenges. Nature-based solutions, through the provision of ecosystem services, can yield numerous benefits for people and address multiple challenges simultaneously. Yet, efforts to mainstream nature-based solutions are impaired by the complexity of the interacting social, ecological, and technological dimensions of urban systems. This complexity must be understood and managed to ensure ecosystem-service provisioning is effective, equitable, and resilient. Here, we provide a social-ecological-technological system (SETS) framework that builds on decades of urban ecosystem services research to better understand four core challenges associated with urban nature-based solutions: multi-functionality, systemic valuation, scale mismatch of ecosystem services, and inequity and injustice. The framework illustrates the importance of coordinating natural, technological, and socio-economic systems when designing, planning, and managing urban nature-based solutions to enable optimal social-ecological outcomes.

description: The reverse martensitic ("austenitic") transformation upon heating of equiatomic nickel-titanium nanoparticles with diameters between 4 and 17 nm is analyzed by means of molecular-dynamics simulations with a semi-empirical model potential. After constructing an appropriate order parameter to distinguish locally between the monoclinic B19' at low and the cubic B2 structure at high temperatures, the process of the phase transition is visualized. This shows a heterogeneous nucleation of austenite at the surface of the particles, which propagates to the interior by plane sliding, explaining a difference in austenite start and end temperatures. Their absolute values and dependence on particle diameter are obtained and related to calculations of the surface induced size dependence of the difference in free energy between austenite and martensite.
