description: We investigate the denaturation dynamics of nucleic acids through extensive molecular dynamics simulations of a coarse-grained RNA hairpin model. In apparent contradiction with Arrhenius' law, our findings reveal that the denaturation time of RNA hairpins is a non-monotonous function of temperature for molecules longer than few persistence lengths, with an optimal temperature above the melting point, $T_m$, at which denaturation occurs fastest. This anomaly arises from the existence of two distinct pathways: ``unidirectional'' unzipping, progressing from one end to the other and favored near $T_m$, and ``bidirectional'' denaturation, where competing unzipping events initiate from both ends at higher temperatures. The two regimes manifest distinct scaling laws for the melting time \textit{vs.} length, $L$, and are separated by a crossover temperature $T_\times$, with $(T_\times-T_m) \sim L^{-1}$. The results highlight the significant role of the helical structure in the out-of-equilibrium dynamics of RNA/DNA denaturation and unveil multiple surprises in a decades-old problem.

description: Erasing a black hole leaves spacetime flat, so light passing through the region before any star forms and after black hole's evaporation shows no time delay, just like a flying mirror that returns to its initial starting point. Quantum radiation from a round-trip flying mirror has not been solved despite the model's mathematical simplicity and physical clarity. Here, we solve the particle creation from worldlines that asymptotically start and stop at the same spot, resulting in interesting spectra and symmetries, including the time dependence of thermal radiance associated with Bose-Einstein and Fermi-Dirac Bogolubov coefficients. Fourier analysis, intrinsically linked to the Bogolubov mechanism, shows that a thermal Bogolubov distribution does not describe the spin statistics of the quantum field.

description: We present a comprehensive study of the structural, magnetic, and thermodynamic properties, as well as the adiabatic demagnetization refrigeration (ADR) performance of NaGdP$_2$O$_7$. Although NaGdP$_2$O$_7$ exhibits antiferromagnetic ordering at a Néel temperature of $T_{\rm N} = 570$ mK in zero field, ADR experiments achieved a minimum temperature of 220 mK starting from $T = 2$ K under an applied magnetic field of $μ_0H = 5$ T. The warm-up time back to $T = 2$ K exceeds 60 hours, which is roughly 50 times longer than that of its Yb-based analogue, underscoring the potential of NaGdP$_2$O$_7$ as an efficient precooling stage in double-stage ADR systems. We show that NaGdP$_2$O$_7$ can be seen as a network of ferromagnetic spin chains with antiferromagnetic interchain couplings and also investigate the influence of antiferromagnetic ordering on the magnetic entropy. We find that the temperature dependence of the entropy plays a more dominant role than its magnetic field dependence in the magnetically ordered state.

description: Collective modes emerge as the relevant degrees of freedom that govern low-energy excitations of atomic nuclei. These modes - rotations, pairing rotations, and vibrations - are separated in energy from non-collective excitations, making it possible to describe them in the framework of effective field theory. Rotations and pairing rotations are the remnants of Nambu-Goldstone modes from the emergent breaking of rotational symmetry and phase symmetries in finite deformed and finite superfluid nuclei, respectively. The symmetry breaking severely constrains the structure of low-energy Lagrangians and thereby clarifies what is essential and simplifies the description. The approach via effective field theories exposes the essence of nuclear collective excitations and is defined with a breakdown scale in mind. This permits one to make systematic improvements and to estimate and quantify uncertainties. Effective field theories of collective excitations have been used to compute spectra, transition rates, and other matrix elements of interest. In particular, predictions of the nuclear matrix element for neutrinoless double beta decay then come with quantified uncertainties. This review summarizes these results and also compares the approach via effective field theories to well-known models and ab initio computations.

description: The excess free energy functional of classical density functional theory depends upon the type of fluid model, specifically on the choice of (pair) potential, is unknown in general, and is approximated reliably only in special cases. We present a machine learning scheme for training a neural network that acts as a generic metadensity functional for truncated but otherwise arbitrary pair potentials. Automatic differentiation and neural functional calculus then yield, for one-dimensional fluids, accurate predictions for inhomogeneous states and immediate access to the pair distribution function. The approach provides a means of addressing a fundamental problem in the physics of liquids, and for soft matter design: How best to invert structural data to obtain the pair potential?

Dante’s Hell in Middle French: Between Respect for the Source and Ambitions of the Translator
Creators: name: Stockebrand, Véréna
Publisher: name: Fondazione Università Ca’ Foscari Venezia, Italia
Year: 2022

description:

This paper focuses on the most ancient French translation of Dante’s Inferno known to this day (Torino, BNU, L.III.17). More specifically, this article studies the first six cantos. The translation is analysed with consideration to three aspects. Firstly, it is compared to the contemporaneous translations to Middle French, between the 15th and 16th centuries, with a focus on methods, conceptualisation of translation, and translators’ goals. Secondly, the Enfer is studied as a translation of Dante’s work by describing the translator’s strategies towards their source. Several linguistic elements are thus discussed, which manifest a will to remain true to the original work, nuanced by some translating mechanisms that show the opposite behaviour. Thirdly, the translation is studied as a literary object per se, through an analysis of stylistic elements that the translator kept or introduced. These three aspects allow a global judgment of the text and highlight its qualities, which will need to be extended to the whole Enfer.

description: In the light of the recent advances in lunar space missions a great interest into using Moon as a future environment for gravitational waves (GWs) detectors has been initiated. Moon offers a unique environment for such detectors due to constrained noise sources, since unlike Earth it does not have ocean and atmosphere. In this paper, we further explore the idea of using Moon as a giant resonator of GWs, a proposal that was first introduced by Weber in 1969. This idea is relaying on the theory how GWs interact with free masses and finally elastic solids, such as is a planet to some approximation. We start by carefully setting up General Relativity (physics) and elastic theory (geophysics) background to be able to derive analytically the coupling between GWs and elastic solids through associated equations of motion. Once the analytical solution is derived, we explore the parameter space this interaction depends on. This eventually provides us with the transfer function, which defines the frequency band of the interest. We show how this interaction robustly depends on the regolith structure by altering the initial lunar model and exploring different regolith models. Our results show that detection might be troublesome in the high frequency regime between 0.1 and 1 Hz, without beforehand constraining the regolith structure with geophysical methods. Finally, we discuss what are the implications of detecting these signals with the future GW detectors build on the Moon.

description: We develop a random sampling method for calculating the time evolution of the Rényi entanglement entropy after a quantum quench from an insulating state in free boson systems. Because of the non-Gaussian nature of the initial state, calculating the Rényi entanglement entropy calls for the exponential cost of computing a matrix permanent. We numerically demonstrate that a simple random sampling method reduces the computational cost of a permanent; for an $N_{\mathrm{s}}\times N_{\mathrm{s}}$ matrix corresponding to $N_{\mathrm{s}}$ sites at half filling, the sampling cost becomes $\mathcal{O}(2^{αN_{\mathrm{s}}})$ with a constant $α\ll 1$, in contrast to the conventional algorithm with the $\mathcal{O}(2^{N_{\mathrm{s}}})$ number of summations requiring the exponential time cost. Although the computational cost is still exponential, this improvement allows us to obtain the entanglement entropy dynamics in free boson systems for more than $100$ sites. We present several examples of the entanglement entropy dynamics in low-dimensional free boson systems.

description: The widely used ReLU is favored for its hardware efficiency, {as the implementation at inference is a one bit sign case,} yet suffers from issues such as the ``dying ReLU'' problem, where during training, neurons fail to activate and constantly remain at zero, as highlighted by Lu et al. Traditional approaches to mitigate this issue often introduce more complex and less hardware-friendly activation functions. In this work, we propose a Hysteresis Rectified Linear Unit (HeLU), an efficient activation function designed to address the ``dying ReLU'' problem with minimal complexity. Unlike traditional activation functions with fixed thresholds for training and inference, HeLU employs a variable threshold that refines the backpropagation. This refined mechanism allows simpler activation functions to achieve competitive performance comparable to their more complex counterparts without introducing unnecessary complexity or requiring inductive biases. Empirical evaluations demonstrate that HeLU enhances model generalization across diverse datasets, offering a promising solution for efficient and effective inference suitable for a wide range of neural network architectures.

description: Understanding urban morphological processes can help architects and urban designers in urban design, especially in urban renewal projects. Since urban form and urban space are closely integrated, the morphological changing process inevitably causes changes in the spatial characteristics that are of concern to urban designers. This study focuses on analysing the relationship between the building interface and the space between buildings. We have made a tool to quantify the characteristics of urban space by setting viewpoints in the urban space, which can measure the distances and height angles from the viewpoints to the surrounding building interfaces. To verify the effectiveness of the tool, two urban areas in Nanjing are selected for case studies. One is an area located in the centre of the city that has undergone tremendous changes and has many high-rise buildings. The other is an area located in the historic conservation area that has changed little and has many traditional houses. Comparing the two areas with quantitative indicators of spatial characteristics, it is found that different urban forms have different spatial characteristics. Based on an in-depth study of the morphological evolution process and social background, four morphological periods are selected for the morphological study of the two areas. By comparing urban morphological processes and spatial characteristics changing process of the areas on the same timeline, the impact of urban morphological change on urban spatial characteristics in different areas and the role of spatial characteristics indicators are analysed. Comparing the two areas with quantitative indicators of spatial characteristics, it is found that different urban forms have different spatial characteristics. In the measurement of the area in the historic conservation area, some spatial indicators that can be used to control the spatial characteristics are found, which are useful for the urban renewal of the historical area.

description: Our research aims to probe the anisotropic matter field around black holes using black hole perturbation theory. Black holes in the universe are usually surrounded by matter or fields, and it is important to study the perturbation and the characteristic modes of a black hole that coexists with such a matter field. In this study, we focus on a family of black hole solutions to Einstein's equations that extend the Reissner-Nordström spacetime to include an anisotropic matter field. In addition to mass and charge, this type of black hole possesses additional hair due to the negative radial pressure of the anisotropic matter. We investigate the perturbations of the massless scalar and electromagnetic fields and calculate the quasinormal modes (QNMs). We also study the critical orbits around the black hole and their properties to investigate the connection between the eikonal QNMs, black hole shadow radius, and Lyapunov exponent. Additionally, we analyze the grey-body factors and scattering coefficients using the perturbation results. Our findings indicate that the presence of anisotropic matter fields leads to a splitting in the QNM frequencies compared to the Schwarzschild case. This splitting feature is also reflected in the shadow radius, Lyapunov exponent, and grey-body factors.

description: The ringdown phase of a gravitational wave (GW) signal from a binary black hole merger provides valuable insights into the properties of the final black hole and serves as a critical test of general relativity in the strong-field regime. A key aspect of this investigation is to determine whether the first overtone mode exists in real GW data, as its presence would offer significant implications for our understanding of general relativity under extreme conditions. To address this, we conducted a reanalysis of the ringdown signal from GW150914, using the newly proposed F-statistic method to search for the first overtone mode. Our results are consistent with those obtained through classical time-domain Bayesian inference, indicating that there is no evidence of the first overtone mode in the ringdown signal of GW150914. However, our results show the potentiality of utilizing the F-statistic methodology to unearth nuanced features within GW signals, thereby contributing novel insights into black hole properties.

description: We use Weyl connection and Weyl geometry in order to construct novel modified gravitational theories. In the simplest case where one uses only the Weyl-connection Ricci scalar as a Lagrangian, the theory recovers general relativity. However, by upgrading the Weyl field to a dynamical field with a general potential and/or general couplings constructed from its trace, leads to new modified gravity theories, where the extra degrees of freedom arise from the Weyl field. Additionally, since the Weyl-connection Ricci scalar differs from the Levi-Civita Ricci scalar by terms up to first derivatives of the Weyl field, the resulting field equations for both the metric and the Weyl field are of second order, and thus the theory is free from Ostrogradsky ghosts. Finally, we construct the most general theory, namely the $f(\tilde{R},\cal{A})$ gravity, which is also ghost free. Applying the above classes of theories at a cosmological framework we obtain an effective dark energy sector of geometrical origin. In the simplest class of theories we are able to obtain an effective cosmological constant, and thus we recover $Λ$CDM paradigm, nevertheless in more general cases we acquire a dynamical dark energy. These theories can reproduce the thermal history of the Universe, and the corresponding dark energy equation-of-state parameter presents a rich behavior.

November 1995 hat Bundeskanzler Kohl im Kontext einer zehntägigen Asienreise, die ihn auch nach Vietnam und Singapur führte, die VR China besucht, und zwar - nach 1984, 1987 und 1993 - bereits das vierte Mal. Während der Visite kam es, wie bereits gemeldet, zur Unterzeichnung von vier Regierungs- und zwölf Handelsabkommen sowie zu den bei solchen Besuchen üblichen Gesprächsrunden. Von Anfang an gab es freilich einige Merkwürdigkeiten, deren Bedeutung sich dem Beobachter nicht schon während, sondern erst lange nach Abschluß der Visite erschlossen, und die sich aus späterer Sicht als Teilstücke einer geschlossenen - und in typisch chinesisch-indirektem Stil vorgetragenen - Gesamtbotschaft erwiesen, deren Inhalt sich unverschlüsselt auf folgende Formel bringen läßt: "Ministerpräsident Li Peng wurde bei seinem Deutschlandbesuch im Sommer 1994 auf eine höchst unziemliche Art und Weise behandelt, wie sie sich mit dem gewachsenen Selbstbewußtsein der VR China keineswegs mehr vereinbaren läßt. Die Volksrepublik zahlt daher mit kleiner Münze heim. Um den Gesamtzusammenhang dieser "Botschaft" deutlich zu machen, seien hier zunächst einige Einzelheiten zum Deutschlandbesuch Li Pengs rekapituliert und anschließend die einzelnen Schritte aufgezählt, die beim diesmaligen China-Besuch Kohls im Sinne einer "Heimzahlung" unternommen wurden.

Industry understanding, drawn from personal experiences of working in public, education and special libraries, utilises my journey as a librarian since graduation in 2005 to discuss barriers faced and methods for breaking through. In my previous position as Teaching and Learning Librarian at Northern Melbourne Institute of TAFE from 35 library staff I was the sole member under 30. In addition I was the youngest member of the Library Management Team by 20 years, providing a perfect example of the Generation Y librarian within a Baby Boomer environment. This experience provides the platform for exploring strategies for understanding and overcoming ageist ideas, generational stereotypes, and employment barriers. Discussion regarding the need to develop sound industry knowledge for survival within the library world will also be raised.

description: Die Provinz Hubei liegt größtenteils nördlich des Mittellaufs des Changjiang (Yangtze) und leitet ihren Namen (Hubei heißt wörtlich "nördlich des Sees") von der Lage nördlich des Dongting-Sees ab. Der Kurzname E ist auf die Zugehörigkeit zur früheren Präfektur E'zhou (seit 589) zurückzuführen. Hubei grenzt im Südosten an Jiangxi, im Osten an Anhui, im Norden an Henan, im Nordwesten an Shaanxi, im Westen an Sichuan und im Süden an die Provinz Hunan, die topographisch Hubeis Spiegelbild darstellt.

description: The in-medium similarity renormalization group (IMSRG) is a powerful and flexible many-body method to compute the structure of nuclei starting from nuclear forces. Recent developments have extended the IMSRG from its standard truncation at the normal-ordered two-body level, the IMSRG(2), to a precision approximation including normal-ordered three-body operators, the IMSRG(3)-$N^7$. This improvement provides a more precise solution to the many-body problem and makes it possible to quantify many-body uncertainties in IMSRG calculations. We explore the structure of $^{44,48,52}$Ca using the IMSRG(3)-$N^7$, focusing on understanding existing discrepancies of the IMSRG(2) to experimental results. We find a significantly better description of the first $2^+$ excitation energy of $^{48}$Ca, improving the description of the shell closure at $N=28$. At the same time, we find that the IMSRG(3)-$N^7$ corrections to charge radii do not resolve the systematic underprediction of the puzzling large charge radius difference between $^{52}$Ca and $^{48}$Ca. We present estimates of many-body uncertainties of IMSRG(2) calculations applicable also to other systems based on the size extensivity of the method.

description: The edge states of a quantum spin Hall insulator exhibit helical properties, which has generated significant interest in the field of spintronics. Although it is predicted theoretically that Rashba spin-orbit coupling can effectively regulate edge state spin, experimental characterization of this spin control remains challenging. Here, we propose utilizing crossed Andreev reflection to probe the efficiency of gate voltage control on edge state spin. We calculate the transport properties of the quantum spin Hall isolators-superconductor heterojunction by using non-equilibrium Green's function method. We find that the probabilities of crossed Andreev reflection, electron transmission, and non-local conductance all include the relative spin rotation angle $θ$ caused by the Rashba spin-orbit coupling in the helical edge states. Notably, when the incident energy is close to the superconducting gap, the differential conductance $G_2\propto-\cosθ$. Thus, the influence of Rashba spin-orbit coupling on edge state spin can be quantitatively characterized by crossed Andreev reflection, which provides a feasible scheme for experimental testing.

description: Decarbonising the industrial sector is vital to reach net zero targets. The deployment of industrial decarbonisation technologies is expected to increase industrial electricity demand in many countries and this may require upgrades to the existing electricity network or new network investment. While the infrastructure requirements to support the introduction of new fuels and technologies in industry, such as hydrogen and carbon capture, utilisation and storage are often discussed, the need for investment to increase the capacity of the electricity network to meet increasing industrial electricity demands is often overlooked in the literature. This paper addresses this gap by quantifying the requirements for additional electricity network capacity to support the decarbonisation of industrial sectors across Great Britain (GB). The Net Zero Industrial Pathways model is used to predict the future electricity demand from industrial sites to 2050 which is then compared spatially to the available headroom across the distribution network in GB. The results show that network headroom is sufficient to meet extra capacity demands from industrial sites over the period to 2030 in nearly all GB regions and network scenarios. However, as electricity demand rises due to increased electrification across all sectors and industrial decarbonisation accelerates towards 2050, the network will need significant new capacity (71 GW + by 2050) particularly in the central, south, and north-west regions of England, and Wales. Without solving these network constraints, around 65% of industrial sites that are large point sources of emissions would be constrained in terms of electric capacity by 2040. These sites are responsible for 69% of industrial point source emissions.

description: We study neutrino oscillations in background matter within the quantum field theory formalism where neutrino mass eigenstates are virtual particles. In this case, neutrino mass eigenstates are mixed owing to the interaction with matter. Assuming that neutrinos are Majorana particles, we find the exact propagators for massive neutrinos accounting for the interaction with matter by solving the analog of the Dyson equation. These propagators are used to calculate the transition probability which coincides with the prediction of the standard quantum mechanical treatment of neutrino flavor oscillations in uniform matter. Finally, we analyze the approximations made in our analysis.

Publisher: name: Swinburne
Year: 2024

description: This paper investigates and provides experimental evidence of the bond characteristics between CFRP and steel plates under elevated temperature exposures. A series of tensile tests was carried out on CFRP/steel plates specimens joined together in double-lap shear joints and subjected to a range of environmental temperatures between 20ºC up to 60ºC which would be usually encountered in civil infrastructure applications. High modulus (640 GPa) unidirectional carbon fibre plies were used in wet lay-up fabrication method to strengthen the composite matrix. Three different epoxy resins were used for the fabrication of the CFRP/steel specimens. The objective of the current experimental work is to determine the ultimate strength, failure patterns, elongation development and lap-shear stress and slip variation under those exposures. This will help in enhancing the competency of using CFRP in retrofitting steel structures at high-temperature environments, usually experienced in civil construction applications.
title: "Transitional Morphologies" studies. An agenda for 2030 between Europe and China

description: The year 2030 will be an important deadline for global economics, society, culture and scientific knowledge. For China it is the perspective of the possible development path, for Europe it is the horizon of the new science and technology research program, for UNO it is the given term to reach a series of sustainable goals. The "Transitional Morphologies" Joint Research Unit (at Southeast University and Politecnico di Torino since 2018) operates on the formal analysis of the dynamics in urban form between China and Italy in order to improve the design practice through new technical and conceptual tools. The keywords to figure out next ten years of studies in urban morphology may be "Transition" and "Tradition" and their role in European and Chinese cultures, overall considering the interaction of human beings and urban space: of course, the interdependence of culture and humanities with new technologies will be a crucial issue looking at the future.

description: L'ensemble de ces notes ont été crée par John Baldwin lors d'une de ses premières périodes de résidence à Paris. Ces documents comprennent tous les magistri qu’il avait pu rencontrer dans ses sources. Aux XIIème et XIIIème siècles, les universités n'existant pas encore, le titre de magister s'il évoque certainement une compétence n'est pas rattaché de façon systématique au passage par les écoles. De surcroît, les magistris sont le plus souvent désignés par leur seul prénom. La lecture de ces données est donc difficile et suppose un long travail pour tenter d'identifier un individu auquel on pourrait rattacher plusieurs mentions. John Baldwin avait donc renoncé à utiliser ces données pour donner un prolongement à sa magnifique étude sur les gradués d'université et leur emploi par les Capétiens et les Plantagenêts. Néanmoins, il a conservé ces données et elles sont potentiellement très utile dans le cadre de Studium, comme le sont toutes les mentions dans les volumes des Fasti Ecclesiae Gallicanae de chanoines portant ce titre de magister sans autres précisions. L'ampleur des dépouillements rend ces données très utiles et nous devons une grande reconnaissance à John Baldwin pour avoir pris la peine de faire photocopier ses fiches et de nous les avoir transmises amicalement.
Les données ainsi que les images des fiches sont accessibles sur le site Internet à l'adresse suivante : http://studium-baldwin.lamop.fr/.
Les transcriptions des fiches ont été effectuées par des étudiants de Paris 1 Panthéon - Sorbonne mais elles n'ont pas été corrigées par la suite.

description: Recent approaches have successfully focused on the segmentation of static reconstructions, thereby equipping downstream applications with semantic 3D understanding. However, the world in which we live is dynamic, characterized by numerous interactions between the environment and humans or robotic agents. Static semantic maps are unable to capture this information, and the naive solution of rescanning the environment after every change is both costly and ineffective in tracking e.g. objects being stored away in drawers. With Lost & Found we present an approach that addresses this limitation. Based solely on egocentric recordings with corresponding hand position and camera pose estimates, we are able to track the 6DoF poses of the moving object within the detected interaction interval. These changes are applied online to a transformable scene graph that captures object-level relations. Compared to state-of-the-art object pose trackers, our approach is more reliable in handling the challenging egocentric viewpoint and the lack of depth information. It outperforms the second-best approach by 34% and 56% for translational and orientational error, respectively, and produces visibly smoother 6DoF object trajectories. In addition, we illustrate how the acquired interaction information in the dynamic scene graph can be employed in the context of robotic applications that would otherwise be unfeasible: We show how our method allows to command a mobile manipulator through teach & repeat, and how information about prior interaction allows a mobile manipulator to retrieve an object hidden in a drawer.
