description: Bei der Modellierung elektrischer Schaltungen ergeben sich Algebro-Differentialgleichungen (DAEs) mit proper formuliertem Hauptterm. Diese Gleichungen müssen z.B. bei der transienten Schaltungssimulation numerisch gelöst werden. Bei den klassischen Ansätzen der Linearen Mehrschrittverfahren oder der Runge-Kutta Verfahren ergeben sich Nachteile, die durch Verwendung von Allgemeinen Linearen Verfahren vermieden werden können. Sowohl Lineare Mehrschrittverfahren als auch Runge-Kutta Verfahren sind als Spezialfälle in dieser allgemeineren Klasse enthalten. Darüberhinaus sind aber neue Verfahren mit verbesserten Eigenschaften möglich. In dieser Arbeit werden DAEs der Schaltungssimulation eingehend studiert und Allgemeine Lineare Verfahren für solche Gleichungen untersucht. Die Verfahrenskonstruktion und Implementierungsfragen werden ausführlich diskutiert. Diese Arbeit erscheint im Logos Verlag Berlin (www.logos-verlag.de, ISBN 3-8325-1353-1).
description: Modelling electrical circuits leads to differential algebraic equations (DAEs) having a properly stated leading term. These equations need to be solved numerically, e.g. in case of a transient analysis of the given circuit. Classical methods such as linear multistep methods or Runge-Kutta schemes suffer from disadvantages that can be overcome by studying general linear schemes. Both Runge-Kutta methods and linear multistep schemes belong to this class as special cases, but there is plenty of room for new methods with improved properties. This work presents both a detailed study of DAEs in the framework of integrated circuit design and a thorough analysis of general linear methods for these kind of equations. The construction and implementation of general linear methods for DAEs is discussed in detail. This work is published by Logos Verlag Berlin (www.logos-verlag.de, ISBN 3-8325-1353-1).

description: Many high dams on the upper Himalayan rivers which have very steep bed slopes are constructed with orifice type of Spillways with low level sluices for flood disposal and flushing of sediments. To assess the performance of spillway physica  model studies were conducted on a 1:50 scale 2-D sectional model. Physical model studies can have a wide range of outcomes depending on the purposes of the model study, although many physical models frequently analyse properties such as velocity patterns, discharge rating curves, water surface profiles, and pressures. The physical measurements highlighted that the spillway is subjected to negative pressures. To overcome this, different spillway profile options were verified using numerical methods.  For this, a commercially available computational fluid dynamics (CFD) program FLOW 3D was used which solves the Reynolds-averaged Navier-Stokes equations along with RNG turbulence closure model. Numerical modelling is quite beneficial when used by the designer in combination with the physical modelling. Numerical modelling enables designers to evaluate several possibilities until they find the hydraulically optimal solution, which can then be evaluated on a physical model, reducing the expense of physical model studies. In order to validate the numerical modelling results, the measured data from physical model studies for the original profile of spillway is used.  Discharge passing through spillways, water surface profiles and pressures were used to compare the results of the physical model and the numerical model. When it was seen that there is reasonably good agreement between the physical and numerical model results, then all other alternatives were analyzed numerically and an alternative having a hydraulically optimal solution was selected to study on the physical model.

description: We investigate a series of manganese oxides, the La0.225Pr0.4(Ca1-xSrx)0.375MnO3 system. The x = 0 sample is a prototype compound for the study of phase separation in manganites, where ferromagnetic and charge ordered antiferromagnetic phases coexist. Replacing Ca2+ by Sr2+ gradually turns the system into a homogeneous ferromagnet. Our results show that the material structure plays a major role in the observed magnetic properties. On cooling, at temperatures below 100 K, a strong contraction of the lattice is followed by an increase in the magnetization. This is observed both through thermal expansion and magnetostriction measurements, providing distinct evidence of magneto-elastic coupling in these phase separated compounds.

description: Several pedagogical experiences in architecture bring literary inputs to teaching, through a multidisciplinary curriculum with courses explicitly focusing on these relationships. Other pedagogical scenarios, even if admitting the relevance of literature references into design, have blended these semantic and structural translations implicitly in their teaching processes. The main goal of this article is to acknowledge the many voices of an implicit transfer between literature and architecture within a learning scenario at the Escola Superior de Belas-Artes do Porto (Fine Arts School in Porto) along with practice.Here, a process of modern acculturation was key, while aiming at modernity filtered by the local culture and tradition, and vice versa. One of its essential figures, Fernando Távora (1923-2005), recurrently quoted Fernando Pessoa while sharing his ideas with students. Reflecting on life and architecture, space and the world, Távora’s discourse was intuitively pedagogical. Fernando Távora embedded literature in his learning and teaching, while being highly engaged with everyday experience and practice. Távora integrated in his lifelong learning the writings of Fernando Pessoa, which among others implicitly contributed to the School of Porto. The article reflects on written essays of Fernando Távora and Alexandre Alves Costa and on architectural works by Álvaro Siza and Eduardo Souto de Moura. For the first, we will consider a specific period in the school, when architects had to complete written and designed pieces to become professors, while for the latter we will pick few architectural examples that illustrate the main argument of this paper.

Publisher: name: University of Illinois at Chicago
Year: 2023

description: Purpose: The authors sought to explore m-learning as a means to provide patient case exposure to pre-clinical medical students in the support of developing their clinical reasoning. Methods: This was a randomized crossover comparison of mobile app use versus live session on diagnostic pathways for patient presentations of dizziness and weakness. Second-year medical students were randomized to access one of four cases (2 weakness pathway, 2 dizziness pathway) in a mobile application, then all attended a live session covering all four cases. Measures for user experience, self-efficacy and clinical reasoning at three study timepoints are reported. Differences between participants and cases analyzed with Chi-squared test. Continuous variables were compared between groups using Kruskal-Wallis or Wilcoxon rank sum test. Interaction contrasts for case, pathway and timepoint were analyzed for changes in self-efficacy and MCQ scores. Results: 42 students spent an average of 26.5 minutes for app case, with no significant differences between groups and case metrics. Learners’ scores improved before and after using the app on the MCQ items that related to their assigned case (mean 14%, SD 6%, interaction contrast p=0.03), but not on MCQ items related to the unassigned case from their pathway (p=0.71) or the case from the other pathway (p=0.78). Before and after the live session, all learners improved uniformly across pathways and cases. Group A alone rated the app as more engaging by Likert Scale (App Mean 5.3, SD 1.3; Lecture Mean 4.4 (1.4), p=.031) Conclusion: M-learning via an application targeting clinical reasoning skills in diagnosis is correlated with case-specific knowledge acquisition and general increases in self-efficacy for pre-clinical medical students. Tailoring level of case complexity to learner level may increase impact.

title: Physical and Numerical Model Studies of Hirakud Dam Additional Spillway –A Case Study

description: Stilling basins are frequently used as energy dissipaters to protect the downstream hydraulic structures from scouring. The stilling basin uses the hydraulic jump as the hydraulic element for dissipating energy in a specific structure. A Stilling basin type of energy dissipator is mainly used for economic reasons; therefore, the Stilling Basin II type has been used on high and earth dam spillways and large canal structures. Basin II type design aims to reduce the hydraulic jump length by installing accessories, such as chute blocks and dentated sill in the stilling basin.
Hirakud Dam is one of the multipurpose projects. In order to safely pass the reassessed additional flood of Hirakud dam, two additional spillways at suitable locations were proposed. One of these was proposed on the main spillway's left bank (Phase-I). Hydraulic model studies of this left bank additional spillway was carried out at CWPRS. This paper is focused on the physical and numerical model studies to assess the performance of the proposed BASIN II type energy dissipator and to finalize the design of the additional spillway on the left bank (Phase-I). Physical model study results revealed that the performance of the original spillway design with energy dissipators was unsatisfactory as the length of the stilling basin provided was insufficient to contain the hydraulic jump. Hence the modification in the length of stilling basin was suggested by the CWPRS. The physical model studies have also been carried out on the modified design and finalized the design of spillway and energy dissipator. The numerical model studies validate the simulation results with the physical model study results for the original and modified design. Numerical Model studies have been carried out on the licence copy of Flow 3D CFD software at CWPRS.
Louisiana romp: examining the performance of traditional Cajun music within a contemporary setting

Year: 2008

description: The Lost Bayou Ramblers, a young Cajun band based in South Louisiana, infuse energy and vivacity into the traditional creative expression of Cajun music, as they travel to share their sound and thus their culture with the world. I suggest that the Ramblers, in the face of globalization, are purposefully engaged in protecting and enhancing their culture by performing this roots music far and near. They offer a compelling performance and thus transport, produce, and extend their culture through music, which serves as a powerful symbol, drawing each audience into participation of it. Through a focus on the specific dynamic between culture, its music, and the performance techniques of these particular cultural practitioners, I examine how music acts as an agent of cultural understanding while simultaneously transforming the place and culture that produced it.
Judicial rhetoric and theatrical program in the Prologues of Terence
Creators: name: Dombrowski, Patrick James
Publisher: name: University of North Carolina at Chapel Hill
Year: 2010

description: This thesis offers a close examination of the language, form, and content of Terence's prologues and reveals how the playwright conceived of and constructed his art. Terence replaces the conventional expository prologue with one that uses judicial rhetoric and Roman legal procedure. He creates a courtroom atmosphere to construct his audience as a jury, whose critical detachment constitutes a unique form of Terentian metatheater. Terence exploits the audience's heightened state of awareness to relate his theories about the adaptation of plays for the Roman stage. Ultimately, the form and content of the prologues reveal Terence's theatrical program: that comic theater is a serious art and should be accessible to all. Chapter 1 places Terence in his generic and rhetorical context. Chapter 2 details the presence of judicial rhetoric in the prologues. Chapter 3 explores the effect of and intent behind Terence's innovations. Chapter 4 deals with the peculiarities of Hecyra.

description: We introduce Z-stability, a notion capturing the intuition that if a function f maps a metric space into a normed space and if the norm of f(x) is small, then x is close to a zero of f. Working in Bishop's constructive setting, we first study pointwise versions of Z-stability and the related notion of good behaviour for functions. We then present a recursive counterexample to the classical argument for passing from pointwise Z-stability to a uniform version on compact metric spaces. In order to effect this passage constructively, we bring into play the positivity principle, equivalent to Brouwer's fan theorem for detachable bars, and the limited anti-Specker property, an intuitionistic counterpart to sequential compactness. The final section deals with connections between the limited anti-Specker property, positivity properties, and (potentially) Brouwer's fan theorem for detachable bars.

description: A near-full-scale physical modelling was performed on the oscillation and instability of open-channel flow in a fish-friendly culvert equipped with full-height sidewall baffles. High-resolution measurements of the instantaneous flow velocity were conducted using a Vectrino+ acoustic Doppler velocimeter (ADV). The physical results were marked by the existence of some low-frequency seiche phenomenon. A well-established triple decomposition technique was applied to the time series of free-surface and velocity time-series. The low-pass components confirmed a unique flow structure, consisting of a high-velocity zone in the main channel and a low-velocity flow reversal within the lateral cavities. The band-pass components corresponded to the low-frequency flow oscillations, highlighting the complicated transverse interactions between the lateral cavity and the main channel. The high-pass velocity components were related to the 'true' turbulence characteristics. The current study provides some further insights into the sustainable design of culverts to assist with upstream fish migration in man-made and natural fast waterways.

description: Along Australian inland waterways, a number of man-made horseshoe obstacles were built for centuries. The permanent structures interacted with the streamflow across a wide range of water discharges including when they are fully-submerged. Their use ranged from water holes and fish trap at low to moderate flows, to large bed roughness and turbulent manipulation at large water discharges. The aim of the study was to gain a sound physical understanding of the hydraulic operation of horseshoe obstacle across a broad range of submergence ratio, ranging from low flows and emergent obstacle to major floods with fully-submerged structures. In this laboratory study, the physical modelling of permeable horseshoe obstacle was undertaken under controlled flow conditions, based upon a Froude similitude. Two physical models were built corresponding to a 5:1 and 20:1 geometric scaling ratio for typical riverine structures. The scale models were 3D-printed with random pattern and a porosity of 0.27, close to the porosity of rockfill material. The physical observations included visual observations, three-dimensional free-surface profiles and detailed velocity measurements. The physical observations showed a broad range of flow patterns, depending upon the submergence ratio. The porosity of the obstacle facilitated some interactions between the seepage and recirculation region, leading to changes in the wake region and its turbulence, compared to a impervious obstacle with the same shape.
A variance analysis of galaxy spectra

Publisher: name: Zenodo
Year: 2022

description: We present a study aimed at understanding the physical phenomena underlying the formation and evolution of galaxies following an alternative analysis of spectroscopic data. Spectra encode the history of star formation and the chemical enrichment of galaxies. The standard approach, based on comparisons with population synthesis models, reveals the presence of substantial degeneracies among the parameters, most notably between age and metallicity. These degeneracies are due to the high correlatedness of the data, along with uncertainties in the parameters that describe the models. The main objective of this project is to use multivariate techniques, such as principal component analysis (PCA), to decipher the star formation histories of galaxies by considering the observational data as the main source of information instead of comparing data and synthesis models. In PCA, information is directly related to the variance of the spectral elements and defines the so-called principal components as eigenvectors produced by the decorrelation of the covariance matrix. We apply PCA to a homogenous sample of galaxy spectra from the Sloan Digital Sky Survey (SDSS) in the velocity dispersion range 100-150km/s, including all three types of galaxies concerning nebular emission – namely star-forming, AGN, and quiescent – according to the standard BPT classification, to assess the properties of the spectra in a model-independent way. Population synthesis is only used a posteriori to give physical meaning to the trends found from PCA. This approach probes different spectral intervals and allows us to assess the variance contributed by nebular emission (from the ionized gas component), the continuum from the stellar photospheres, as well as the stellar absorption lines. Our preliminary results find that galaxy spectra are overall highly compressible, with one component locking a large fraction of total variance, especially in star-forming and AGN galaxies, a result that is independent of the contribution from emission lines. Moreover, the highest fraction of this variance is contributed by the continuum. However, we note that the higher-order principal components cannot be simply ascribed to noise and also encode, in a cumulative sense, a large amount of information. By projecting the observational data onto the lower dimensional parameter space spanned by the principal components, we identify subclasses within each set of galaxies that are explored regarding their evolutionary phase, a result that enables us to understand the transition from star formation to quiescence and the role of AGN.

description: The Great Salt Lake is of environmental and economic value yet is threatened by various factors including drought and water diversion for irrigation purposes.  Management efforts are required to preserve this saline lake; such efforts include accurately estimating the exchange flow through an opening in a railroad causeway that divides the lake.  This study investigated two modeling approaches for predicting these discharges, a physics-based computational fluid dynamics model and a data-driven artificial neural network model. Good agreement was found between both models, and the advantages each provides to water management efforts are noted.  Results indicate that, regardless of the modeling tool, accurate field data is invaluable when studying a hydraulic structure.

description: We use the Illustris-1 simulation to explore the capabilities of Hubble and James Webb Space Telescope data to analyze the stellar populations in high-z galaxies, taking advantage of the combined depth, spatial resolution, and wavelength coverage. For that purpose, we use simulated broad-band ACS, WFC3 and NIRCam data and 2-dimensional stellar population synthesis (2D-SPS) to derive the integrated star formation history (SFH) of massive (M∗ > 1010 M☉) simulated galaxies at 1 < z < 4 that evolve into a local M∗ > 1011 M☉ galaxy. We explore the potential of HST and JWST datasets reaching a depth similar to those of the CANDELS and ongoing CEERS observations, respectively, and concentrate on determining the capabilities of this dataset for characterizing the first episodes in the SFH of local M∗ > 1011 M☉ galaxies by studying their progenitors at z > 1. The 2D-SPS method presented in this work has been calibrated to robustly recover the cosmic times when the first star formation episodes occurred in massive galaxies, i.e., the first stages in their integrated SFHs. In particular, we discuss the times when the first 1% to 50% of their total stellar mass formed in the simulation. We demonstrate that we can recover these ages with typical median systematic offset of <5% and scatter of ~20%-30%.
On neutron stars in f(R) theories: small radii, large masses and large energy emitted in a merger

description: In the context of f(R) gravity theories, we show that the apparent mass of a neutron star as seen from an observer at infinity is numerically calculable but requires careful matching, first at the star's edge, between interior and exterior solutions, none of them being totally Schwarzschild-like but presenting instead small oscillations of the curvature scalar R; and second at large radii, where the Newtonian potential is used to identify the mass of the neutron star. We find that for the same equation of state, this mass definition is always larger than its general relativistic counterpart. We exemplify this with quadratic $R^2$ and Hu-Sawicki-like modifications of the standard General Relativity action. Therefore, the finding of two-solar mass neutron stars basically imposes no constraint on stable f(R) theories. However, star radii are in general smaller than in General Relativity, which can give an observational handle on such classes of models at the astrophysical level. Both larger masses and smaller matter radii are due to much of the apparent effective energy residing in the outer metric for scalar-tensor theories. Finally, because the f(R) neutron star masses can be much larger than General Relativity counterparts, the total energy available for radiating gravitational waves could be of order several solar masses, and thus a merger of these stars constitutes an interesting wave source.

description: Spillways may require converging sidewalls because of site or economy constraints. The adverse effects of the converging walls on supercritical flows include the formation of standing waves. In this context, numerical simulations were carried out using the Smoothed Particle Hydrodynamics (SPH) method. The numerical results were compared with experimental data acquired on a spillway model composed of a broad crested weir followed by a 1V:2H sloping chute with wall convergence angle of 9.9º or 19.3º, for a range of discharges. The flow depths at the spillway centerline were reasonably well predicted by the numerical simulations, except on the transition from the weir to the chute. Experimental data and numerical results showed that the sidewall flow depth normalized by the centerline flow depth (uninfluenced by the converging wall), tended to increase along the spillway, reaching maximum values of approximately 2 and 5, for wall convergence angles of 9.9° and 19.3°, respectively. Numerical cross-sectional flow depth profiles were also obtained, showing distinct shapes of the standing waves, depending on the wall convergence angle and position along the spillway. Overall, the simulated development of the standing wave width compared well with the experimental counterparts. The experimental velocity profiles obtained at the spillway centerline with wall convergence angle of 9.9º were also compared with those obtained numerically and the results revealed a fairly good prediction, except near the upstream end of the chute and close to the invert.

Cependant, la faiblesse de la nature humaine ou le péché sont des obstacles. Ainsi, dans le cadre de l’exercice de l’autorité et de l’obéissance peuvent se glisser des comportements atteignant la santé et la sécurité d’un membre ou de plusieurs. La présente recherche étudie attentivement l’autorité et l’obéissance dans le c. 501 du Code de 1917, dans les cc. 601, 618, 619 du Code de 1983 ainsi que dans les documents de l’enseignement de l’Église sur la vie consacrée postérieurs à la publication du Code. À la suite de cela, elle étudie la manière dont la société séculière à partir du début du début du XXe siècle avec la création des grandes organisations internationales s’est souciée de la santé et de la sécurité des travailleurs. Cela va mettre en évidence qu’un des enjeux de la société du XXIe siècle concerne les risques psychosociaux au travail. L’étude, après avoir regardé la manière dont les cc. 231, § 2 et 1286, 1 sont appliqués dans différents diocèses, se termine par une synthèse présentant un outil complémentaire pour le gouvernement d’un institut religieux soucieux de mieux prendre en compte la santé et la sécurité de ses membres. Par ce moyen, un institut peut mieux identifier et se prémunir des abus présents en son sein.

description: Besides tunneling in static potential landscapes, for example, the Wentzel-Kramers-Brillouin (WKB) approach is a powerful nonperturbative approximation tool to study particle creation due to time-dependent background fields, such as cosmological particle production or the Sauter-Schwinger effect, i.e., electron-positron pair creation in a strong electric field. However, our understanding of particle creation processes in background fields depending on both space and time is rather incomplete. In order to venture into this direction, we propose a generalization of the WKB method to truly spacetime-dependent fields and apply it to the case of a spacetime-dependent mass.

description: In order to explain the current acceleration of the Universe, the fine tuning problem of the cosmological constant $Λ$ and the cosmic coincidence problem, different alternative models have been proposed in the literature. We use the most recent observational data from CMB (Planck 2018 final data release) and LSS (SDSS, WiggleZ, VIPERS) to constrain dynamical dark energy (DE) models. The CMB shift parameter, which traditionally has been used to determine the main cosmological parameters of the standard model $ΛCDM$ is employed in addition to data from redshift-space distortions through the growth parameter $A(z)=f(z)σ_{8}(z)$ to constrain the mass variance $σ_{8}$. BAO data is also used to study the history of the cosmological expansion and the main properties of DE. From the evolution of $q(z)$ we found a slowdown of acceleration behaviour at low redshifts, and by using the Akaike and Bayesian Information Criterion (AIC, BIC) we discriminate different models those that are better suited to the observational data, finding that the interactive dark energy (IDE) model is the most favoured by observational data, including information from SNIa and Hz. The analysis shows that the IDE model is followed closely by EDE and $ΛCDM$ models, which in some cases fit better the observational data with individual probes.

Publisher: name: Utah State University

description: Existing methods to simulate air entrainment in stepped spillways are based on a sub-grid air-entrainment function that
accounts for the incorporation of air through the air-water interface; a transport equation for the bubbly phase is then solved inside the water domain. Unfortunately, these techniques are unable to represent bulking, i.e., the increase in water depths after the inception point. In this work, we introduce a novel method for the simulation of flow in stepped spillways (including the aerated region). The new air-entrainment model is implemented in the OpenFOAM platform and couples an air-concentration-transport equation with the traditional Volume-of-Fluid (VoF) method to account for bulking. The model was calibrated and validated using the experimental data by Amador (2005) and Felder and Chanson (2013). Air concentration and mean free surface location in the aerated region (defined as where the concentration of air is 90%) are analyzed on the top of the steps as well as inside the cavities. Very satisfactory agreement in the wall-normal distribution of air concentrations between model and experiments was obtained. The model showed to be capable of predicting bulking in stepped spillways, without the need for ad-hoc treatments

description: We consider N=2 supergravity in four dimensions, coupled to an arbitrary number of vector- and hypermultiplets, where abelian isometries of the quaternionic hyperscalar target manifold are gauged. Using a static and spherically or hyperbolically symmetric ansatz for the fields, a one-dimensional effective action is derived whose variation yields all the equations of motion. By imposing a sort of Dirac charge quantization condition, one can express the complete scalar potential in terms of a superpotential and write the action as a sum of squares. This leads to first-order flow equations, that imply the second-order equations of motion. The first-order flow turns out to be driven by Hamilton's characteristic function in the Hamilton-Jacobi formalism, and contains among other contributions the superpotential of the scalars. We then include also magnetic gaugings and generalize the flow equations to a symplectically covariant form. Moreover, by rotating the charges in an appropriate way, an alternative set of non-BPS first-order equations is obtained that corresponds to a different squaring of the action. Finally, we use our results to derive the attractor equations for near-horizon geometries of extremal black holes.

description: The spillway is among the most important structures of a dam project. The operation of spillway gates during the flood and fulfilling the downstream requirement is one of the main problems in reservoir management. Generally, the equal opening of all the gates during spillway operation is mostly preferred for maintaining an equal distribution of discharge in the energy dissipator and at the downstream side. A systematic study is required to determine the ability of the spillway to pass the discharge at various reservoir water levels through a specific opening of gates and assess the performance for the safety of the structure. The design of each project is unique and site-specific. A physical model is an indispensable tool to optimise the hydraulically efficient and economical design of spillways. However, the evaluation of spillway performance especially for the partial operation of gates is a time-consuming task on the physical model. Nowadays, the computational fluid dynamics technique is becoming popular in modelling spillway flows. This paper discusses the studies carried out for overflow spillway for gated and ungated operations. The Computational fluid dynamics software FLOW-3D was used for numerical simulation. The numerical model was validated by comparing the results with the physical model for ungated operations. The results in terms of design discharge passed over the spillway and corresponding pressures over the spillway surface computed using a numerical model were found closer to the results obtained from the physical model. Numerical model studies were extended further for the gated operation. Large data was generated which was used to create discharging capacity plots and evaluate the performance of the spillway for operating the spillway with different openings of gates at various reservoir water levels.

description: The integrability condition of the Ising model is understood as the SU(2) integrability condition and also as the model parameterized by the elliptic function, where the integrability condition is understood as the addition theorem of the elliptic function. The generalization of this integrability condition is to find the solution of the higher rank Lie group integrability condition and also to find the model parameterized by higher genus hyperelliptic function. For the preparation of this purpose, we give the explicit formula of the addition formula for g = 2 hyperelliptic function.

description: Footprint 30 explores the work of French philosopher of technology Bernard Stiegler (1952–2020) to critically rethink the built environment in terms of a constructed yet emergent existential niche. Foremost concerned with technics, the purchase of Stiegler’s thinking and conceptual apparatus is to be found in the proposition of a novel theoretico-methodological turn towards epiphylogenetic processes. Yet to be embraced by discourses on architectural and cultural technologies, the notion of epiphylogenesis implies a kind of recursive path-dependent co-evolution of living systems with non-living means, especially technics. This sympoietic vision – of how culture-shaping technics and technical ensembles like cities (trans)form us – urges us to rethink how environments re-shape ontogenetic processes. The contributions to the issue call for a radical recasting of the architectural discipline by reconsidering the ‘what’ of technicity as constitutive of a (post)human ‘who’. Issue editors: Robert A.

description: This issue of Footprint questions the complex concept of populism, explaining how, in recent debates, it has more and more often been related to architectural issues. Partly based on the analysis of political philosopher and historian Jan-Werner Müller, our understanding of the term reaches to both ends of the political spectrum. Yet rather than simply aiming to provide a clear definition of populism, this issue sheds more light on a debated concept, showing its multi-facetted aspects in relation to space and aesthetics. Through the categories of media, politics and aesthetics, this issue also shows the logical progression between the different pieces included. Acknowledging the complex nature of the word populism is essential for the understanding of the variety of takes included in this issue. Issue's editors: Salomon Frausto and Léa-Catherine Szacka

description: We examine the group theoretical reason why various two dimensional statistical integrable models, such as the Ising model, the chiral Potts model and the Belavin model, becomes integrable. The symmetry of these integrable models is SU(2) and the Boltzmann weight can be parametrized by the elliptic function in many cases. In this paper, we examine the connection between the SU(2) symmetry and the elliptic function in the statistical integrable models.

description: Single-molecule topological insulators are promising candidates as conducting wires over nanometre length scales. A key advantage is their ability to exhibit quasi-metallic transport, in contrast to conjugated molecular wires which typically exhibit a low conductance that decays as the wire length increases. Here, we study a family of oligophenylene-bridged bis(triarylamines) with tunable and stable mono- or di-radicaloid character. These wires can undergo one- and two-electron chemical oxidations to the corresponding mono-cation and di-cation, respectively. We show that the oxidized wires exhibit reversed conductance decay with increasing length, consistent with the expectation for Su–Schrieffer–Heeger-type one-dimensional topological insulators. The 2.6-nm-long di-cation reported here displays a conductance greater than 0.1G0, where G0 is the conductance quantum, a factor of 5,400 greater than the neutral form. The observed conductance–length relationship is similar between the mono-cation and di-cation series. Density functional theory calculations elucidate how the frontier orbitals and delocalization of radicals facilitate the observed non-classical quasi-metallic behaviour.

description: Conformal nets are a mathematical model for conformal field theory, and defects between conformal nets are a model for an interaction or phase transition between two conformal field theories. In the preceding paper of this series, we introduced a notion of composition, called fusion, between defects. We also described a notion of sectors between defects, modeling an interaction among or transformation between phase transitions, and defined fusion composition operations for sectors. In this paper we prove that altogether the collection of conformal nets, defects, sectors, and intertwiners, equipped with the fusion of defects and fusion of sectors, forms a symmetric monoidal 3-category. This 3-category encodes the algebraic structure of the possible interactions among conformal field theories.
