Exploring the official and unofficial paratexts of Chinese indie video games on Steam Pages
Authors: Moreno García Luis Damián 
Published: January 2025

Abstract
The present study explores Chinese indie video game Steam Pages focusing on two types of complementary epitexts on
the Steam platform: “official” paratexts, authored by game creators, and “unofficial” paratexts created by game players. The
functions of such official and unofficial paratexts are probed by following Batchelor’s authorial classification (2018). The paper applies the concept of paratexts to discuss the empowerment of
reviewers, curators and gamers and their texts (as paratexts) as essential components of the Pages, while attempting to cast light
onto creator-gamer interactions. Tentative findings include both reinforcing and contradicting cross-interactions between official
and unofficial paratexts, as well as differing functions that help shape Steam Pages into cohesive components inside Steam’s
social ecosystem.
Beyond inter- and transdisciplinarity
Authors: Morton Tom 
Published: January 2025

Abstract
While English-medium instruction (EMI) is growing rapidly as a field of practice, there is a lack of agreement around its conceptual and terminological boundaries, and its purposes are often ill defined. To deal with the complexity of the phenomena it addresses, it has been argued that EMI should adopt an interdisciplinary or transdisciplinary perspective. This conceptual article adopts a different position, arguing that EMI is best seen as an example of a “practical assemblage” (Pennycook, 2024), which draws on different epistemic resources to engage with its own set of problems, rather than vying to become a discipline in itself. Using the sociological lens of Legitimation Code Theory (Maton, 2014), the article proposes a framework for positioning EMI as an autonomous field of inquiry, addressing its own problem-situations and research questions. The analysis finds that, rather than building boundaries around itself, EMI as a practical assemblage would be better placed to open itself to ideas from other domains of enquiry while maintaining its autonomy in working on its own problems for its own purposes.
“We pursue justice”
Authors: Dehlsen Mark , Kalfagianni Agni , Sénit Carole-Anne 
Published: January 2025

Abstract
Philanthropic foundations are key players in global sustainability governance. This paper explores the
legitimation strategies these foundations use to justify their actions and positions in the sustainable development community. By
combining Theo van Leeuwen’s legitimation framework with our novel analytical justice framework, we offer a new tool to analyse
hard-to-research actors. Analysing data from 41 foundation websites, we find that foundations emphasize Global Egalitarian
Cosmopolitanism in their values and objectives to align with global sustainability discourses. However, Libertarian ideas dominate
when discussing programs and founders. This indicates there may be internal conflicts within foundations over the relationship
between extreme wealth accumulation required for global philanthropy and sustainability objectives. In turn, this has implications
for how foundations position themselves as agents of justice in sustainable development. While discourse analysis provides
valuable insights into philanthropic legitimation strategies, further research is needed to fully understand how justice
intersects with organizational decision-making.
Embodied vulnerability
Authors: Moriarty Máiréad 
Published: January 2025

Abstract
A recent move in semiotic landscape studies is to examine how those placed on the margins of society counteract
such regulation by using the semiotic landscape as a platform to enact regimes of voice and agency where scholarly attention has
begun to study the spatial representations of vulnerability and how individuals othered by these processes fight back (see for
example Milani & Levron, 2019; Moriarty,
2019). Drawing on Butler’s (2004) work on corporeal vulnerability, the aim
of this paper is to put forward embodied vulnerability as a useful lens for examining semiotic landscapes of
vulnerability. The aim of this paper is to put forward skinscape as a resource for embodied vulnerability through the prism of
youth suffering from suicidal behaviour in the Republic of Ireland. In drawing on a skinscape images and tattoo narratives, this
paper will show how those engaging in suicidal behaviours draw on tattoos as a form of embodiment of their vulnerability that
leads to healing and comfort.

Resumen
Este artículo se propone una caracterización de la dinámica discursiva de las páginas de promoción turística en Facebook a partir de la estrategia comunicativa de la intensificación pragmática. A través de un análisis de corpus, se pretende estudiar el comportamiento que presenta este fenómeno en tres ciudades, Madrid, Sevilla y Valencia, para caracterizar empíricamente el comportamiento interactivo que se da entre los gestores de estas páginas y sus destinatarios. así como su función en el discurso del turismo en la red. De forma más específica, se indica qué tipo de comentarios o post tienen como resultado mayor interactividad y generan mayor presencia de intensificación por parte de los usuarios de Facebook. Los resultados del análisis realizado muestran que se pueden determinar comportamientos discursivos y pragmáticos que generan mayor respuesta por parte de los interlocutores así como un mayor uso de estrategias valorizadoras al servicio de la construcción y proyección de una imagen turística. Los patrones discursivos que más se acercan a los usos interpersonales y colaborativos propios de la red social Facebook son aquellos que obtienen mayor respuesta y con intensificación por parte de los receptores de estos comentarios.
Interrupciones y « voz propia »

Published: January 2025

Resumen
Este artículo presenta una innovadora propuesta metodológica para el análisis de las interacciones en juicios
penales con la intervención de intérpretes judiciales en la combinación chino-español. Los juicios fueron transcritos a partir de
las grabaciones oficiales en vídeo de los Juzgados de lo Penal de Barcelona. El objetivo es describir la metodología empleada para
identificar, categorizar y analizar las soluciones que los intérpretes adoptan ante problemas interaccionales. Se detallan las
categorías de anotación de estos problemas y se analizan las interacciones designadas como « voz propia » y las interrupciones,
distinguiendo si se consideran justificadas o no. Los resultados muestran una alta incidencia de voces propias injustificadas por
parte del intérprete, especialmente en intervenciones que obtienen información no solicitada por los operadores judiciales y en
las que el intérprete responde en lugar del declarante. Las interacciones injustificadas identificadas evidencian que los
intérpretes judiciales de chino incumplen la norma de imparcialidad prevista en la mayoría de los códigos deontológicos. Además,
la falta de reacción de los operadores judiciales sugiere un claro desconocimiento de la perspectiva interaccional de la
interpretación judicial por parte de los profesionales de la justicia.
La asimetría conceptual en la traducción del medio ambiente
Authors: Cabezas-García Melania , Fuentes-Pineda Teresa 
Published: January 2025

Resumen
La asimetría conceptual se produce cuando un concepto no se codifica del mismo modo en dos lenguas debido a diferencias culturales, entre otros factores, y puede dar lugar a la inexistencia de equivalencia en la lengua de llegada. Este trabajo investiga los problemas de traducción en la combinación lingüística francés>español derivados de la asimetría conceptual en el ámbito medioambiental, y propone soluciones adaptadas a diferentes situaciones comunicativas. Para ello, nos centramos en tres conceptos referidos a animales endémicos de Francia que no existen en España (chamois, bouquetin des alpes y sittelle corse). Con vistas a analizar estos conceptos y los términos empleados para nombrarlos en español, se compiló un corpus monolingüe en español que contiene textos especializados sobre estas tres especies animales. Por otro lado, empleamos dos clasificaciones con el fin de: (i) estudiar la variación terminológica presente en español y (ii) analizar las estrategias de traducción empleadas en los casos de inexistencia de equivalencia en la lengua de llegada.
Rank-deficient square-root information filter for unified GNSS precise point positioning model
Authors: Zheng Yanning 
Published: January 2025

Abstract
Numerous global navigation satellite system (GNSS) precise point positioning (PPP) models have been developed by reparameterizing the rank-deficient (RD) original model, which performs well under standard conditions. However, predefined reparameterization introduces challenges, such as incomplete satellite observation utilization and the complexity of modeling original parameters, whose solutions are often model-specific and lack unification. To address these issues, we propose the RD-square-root information filter (RD-SRIF) for processing RD observational problems. This approach enables a unified PPP model based on the original model constructed at runtime, facilitating universal solutions to challenges posed by predefined reparameterization. Theoretical analysis and experimental results demonstrate that the unified model matches the performance of classic models for normal observational conditions while offering several advantages. It effectively incorporates incomplete satellite observations to enhance ionosphere modeling, and ensures rigorous modeling of original parameters for improved failure detection in dynamic models and single-frequency PPP performance. Moreover, it surpasses classic models in addressing complex challenges, such as smartphone-based PPP. The unified PPP model makes it easier to solve the modeling problems of PPP, while the RD-SRIF may also be beneficial for other GNSS or non-GNSS algorithms.
Time-dependent billiards, variational method, and invariant tori
Authors: Zhang Xiaoming , Li Denghui , Liu Xianbin 
Published: January 2025

Abstract
In this work, we study the dynamics of two-dimensional convex billiards with time-periodically perturbed boundaries. Due to the non-conservation of the particle’s energy, the billiard map becomes a four-dimensional twist map. Rather than analyzing this high-dimensional twist map directly, we develop a novel variational approach to address this problem. Additionally, we present and prove a Lagrangian version of Moser’s twist map theorem in higher dimensions to support our variational method. As a result, we demonstrate the existence of invariant tori near the boundary of a convex billiard when the time-periodic perturbation is sufficiently small. In addition, for a time-periodic perturbed circular billiard, the invariant tori are not necessarily located near the boundary.

Objective. In-beam positron emission tomography (PET) has important development prospects in real-time monitoring of proton therapy. However, in the beam-on operation, the high bursts of radiation events pose challenges to the performance of the PET system. Approach.

The in-beam PET system achieved a single count rate of 48 Mcps at the activity of 144.9 MBq, an absolute sensitivity of 2.717%, and a spatial resolution of approximately 2.6 mm (full width at half maximum) at the center of the field-of-view. When imaging a Derenzo phantom, the system could resolve rods with a diameter of 2.0 mm. Time-dynamic [18F]-Fluorodeoxyglucose mouse imaging was performed, demonstrating the metabolic processes in the mouse. This shows that the in-beam PET system has the potential for biology-guided proton therapy. The in-beam PET system was used to monitor the range of a 130 MeV proton beam irradiating a polymethyl methacrylate (PMMA) phantom, with a beam intensity of

p s−1 and an irradiation duration of one minute. PET data were acquired only during the one-minute irradiation. We simulated the range shift by moving the PMMA and adding an air gap, showing that the error between the actual and the measured range is less than 1 mm. Significance. The results demonstrate that the system has a high count rate and the capability of range monitoring in beam-on operation, which is beneficial for achieving real-time range verification of proton beams in the future.
Robust stochastic optimisation strategies for locoregional hyperthermia treatment planning using polynomial chaos expansion
Authors: Groen Jort A , Herrera Timoteo D , Crezee Johannes , Kok H Petra 
Published: January 2025

Abstract

Objective. Conventional temperature optimization in hyperthermia treatment planning aims to maximize tumour temperature (e.g. T90; the temperature reached in at least 90% of the tumour) while enforcing hard constraints on normal tissue temperature (max(Ttissue) ⩽45 °C). This method generally incorrectly assumes that tissue/perfusion properties are known, typically relying on average values from the literature. To enhance the reliability of temperature optimization in clinical applications, we developed new robust optimization strategies to reduce the impact of tissue/perfusion property uncertainties. Approach. Within the software package Plan2Heat, temperature calculations during optimization apply efficient superposition of precomputed distributions, represented by a temperature matrix (T-matrix). We extended this method using stochastic polynomial chaos expansion models to compute an average T-matrix (T
avg) and a covariance matrix C to account for uncertainties in tissue/perfusion properties. Three new strategies were implemented using T
avg and C during optimization: (1) T
avg90 maximization, hard constraint on max(T
tissue), (2) T
avg90 maximization, hard constraint on max(T
tissue) variation, and (3) combined T
avg90 maximization and variation minimization, hard constraint on max(T
tissue). Conventional and new optimization strategies were tested in a cervical cancer patient. 100 test cases were generated, randomly sampling tissue-property probability distributions. Tumour T90 and hot spots (max(T
tissue) >45 °C) were evaluated for each sample. Main Results. Conventional optimization had 28 samples without hot spots, with a median T90 of 39.7 °C. For strategies (1), (2) and (3), the number of samples without hot spots was increased to 33, 41 and 36, respectively. Median T90 was reduced lightly, by ∼0.1 °C–0.3 °C, for strategies (1–3). Tissue volumes exceeding 45 °C and variation in max(T
tissue) were less for the novel strategies. Significance. Optimization strategies that account for tissue-property uncertainties demonstrated fewer, and reduced in volume, normal tissue hot spots, with only a marginal reduction in tumour T90. This implies a potential clinical utility in reducing the need for, or the impact of, device setting adjustments during hyperthermia treatment.
Magnetic field characterization of edge currents in quantum spin Hall insulators
Authors: A Pinto Felipe , C Heitzer Ricardo , Dvorquez Eitan , Rodriguez Roberto , Sun Qiang , D Greentree Andrew , C Gibson Brant , R Maze Jerónimo 
Published: January 2025

Abstract
Quantum spin Hall (QSH) insulators are materials with nontrivial topological properties, characterized by helical edge currents. In 2D strips, the application of a bias voltage along the edge generates a magnetization that can be measured using quantum sensors and magnetometry techniques. In this work, we calculate the magnetic field in the vicinity of the edge and explore the potential role of nitrogen-vacancy centers in diamond as local probes for the characterization of QSH edge states in topological insulators. We characterize the magnetic field near the edges produced by both electron currents and spin accumulation at the edge. We focus on identifying the position from the edge at which the effects of spin accumulation become detectable. We observe that a larger gap between the conduction and valence bands, along with a lower Fermi velocity, results in a stronger magnetic field, with the detectable spin accumulation being more concentrated near the edge. Conversely, a smaller gap results in a slight reduction in the magnetic field magnitude, but the field associated with spin accumulation becomes detectable further from the edge. This work provides insights that could be useful for the characterization of topological materials and the development of novel electro-optical devices.
Quantum pseudo-harmonic oscillator potential in non-Euclidean space: application to diatomic molecules
Authors: Özfidan Aysel 
Published: January 2025

Abstract
The present work analyzes a physical system with a quantum pseudo-harmonic oscillator in three-dimensional constant curvature spaces within the framework of non-relativistic theory. We present expressions for the energy equation and radial wavefunctions that depend on the curvature parameter κ, using the functional analysis approach and the asymptotic iteration method. Additionally, we calculate the energy eigenvalues for diatomic molecules N2, H2, and ScH as a function of the constant curvature κ. Using the Hellmann-Feynmann theorem, we derive expressions for the curvature-dependent expectation values of r−2 and p2, which we detail for the diatomic molecule system in this work. Furthermore, we perform a comparative analysis of the results for non-Euclidean space (spherical and hyperbolic spaces with constant curvature) and Euclidean space.

Abstract
Low-resistance Ohmic contact is critical for the high efficiency GaN-based laser diodes. This study investigates the introduction of the In0.15Ga0.85N contact layer on the specific contact resistance. Experimental results reveal that adopting the In0.15Ga0.85N contact layer yields a minimized specific contact resistance of 2.57 × 10−5 Ω·cm2 which is two orders of magnitude lower than the GaN contact layer (7.61 × 10−3 Ω·cm2). A decrease in the specific contact resistance arises from the reduction of the barrier between the metal and p-type In0.15Ga0.85N. To develop an optimal metal electrode combination on the In0.15Ga0.85N contact layer, the Pd/Au and Ni/Au electrode stacks which are most commonly used in the formation of Ohmic contact with p-GaN are investigated. Metal stack of 10/30 nm Pd/Au is demonstrated effective in reducing the specific contact resistance to 10−5 Ω·cm2 level. The mechanism of the variation of the specific contact resistance under different annealing atmospheres is explained by auger electron spectroscopy.
Effect of plasma beta on the nonlinear evolution of m/n = 2/1 double tearing mode in high Lundquist number regime

Published: January 2025

Abstract
The existing results indicate that in the large Lundquist number regime, plasmoids play an important role in the growth and saturation of the double tearing mode (DTM). In this paper, the effect of plasma beta on the nonlinear evolution of the m/n = 2/1 DTM in large Lundquist number regime is numerically investigated in a cylinder geometry. The results demonstrate that the impact of plasma beta on plasmoid dynamics varies significantly with the separation distance between rational surfaces. In the small separation regime (

W cm−2 in the interest of inertial fusion energy. Angular-resolved distributions of scattered light were diagnosed, which demonstrated that the laser absorption rate is enhanced by increasing the laser bandwidth. This enhancement is primarily owing to the mitigation of stimulated Brillouin scattering. Meanwhile, the inherent temporal fluctuation of laser intensity caused by bandwidth results in more intense stimulated Raman scattering, particularly regarding the sidescattering. These findings indicate that the requirement of laser bandwidth used in inertial fusion energy should exceed the moderate level to achieve comprehensive mitigation of LPI.
