Recurrent change in pronouns
Authors: Dalle Ceste Carlo 
Published: November 2024

Abstract
The reconstruction of Western Oceanic subject markers points to a recurrent history of grammaticalisation
and paradigm (re)formation. With the notable exception of Ross & Lithgow (1989),
this topic has received little attention. Yet subject markers are relevant grammatical markers in Oceanic languages, in that
they not only index the subject on the VP but may also carry the additional function of expressing TAM distinctions. Both the
pronominal and TAM-marking formatives in Western Oceanic subject markers point to a variety of sources (e.g., free pronouns,
possessive pronouns, etc.), and different processes of formation that often result in segmentation asymmetries. Despite
hindering a sound reconstruction, these factors may tell us more about the dynamics of change reshaping such relevant functors
in Western Oceanic languages.
The diachronic development of postverbal dé 得 in Chinese
Authors: Meisterernst Barbara 
Published: November 2024

Abstract
The modal dé 得 is one of the modal verbs of possibility in Late
Archaic Chinese (LAC) and Early Middle Chinese (EMC). Different from other modals verbs of possibility, which are confined to
preverbal position, dé 得 ‘obtain, get, manage to, can’ occurs in two
different positions in Modern Chinese and other Sinitic languages: preverbal and postverbal. This chapter argues that the two
different functions of de in modern Sinitic languages reflect two syntactic instantiations of de in LAC and
EMC. The preverbal modal auxiliary developed from the modal auxiliary verb dé ‘manage to, can’, which only
allows a vP complement, and the postverbal de developed from the lexical verb dé
‘get, obtain’, which allows a CP complement.
A cognitive-typological perspective on the origins of causative‑applicative polysemy
Authors: Van Gysel Jens E. L. 
Published: November 2024

Abstract
In many languages, one morpheme functions both as a causative and as an applicative. Researchers such as
Croft (1991) and Tuggy (1988) have
noted the conceptual similarities between these functions, but the origins and conceptual mechanisms of change which
cross-linguistically lead towards such polysemies have not been studied. This study investigates 88 languages, in which 11
polysemous causative-applicative morphemes were found. Extensions from etymological applicatives towards a causative function,
and vice versa, are attested, although no etymological causatives which have become productive as applicatives were found. I
argue that the conventionalisation of implicatures and other mechanisms of change allow such extensions to advance gradually
over a continuum of valency-increasing functions, or more directly between conceptually further removed causatives and
benefactive applicatives.
La ortografía en la enseñanza de ELE
Authors: Díez Plaza César L. 
Published: November 2024

Resumen
El objetivo de este trabajo es explicar el papel de la ortografía en el aprendizaje de la
pronunciación del español y proponer maneras de integrarla en el aula de ELE. Para ello, partimos de la idea de que la
ortografía es una técnica que ayuda a componer textos escritos valorados como correctos y que debe aprenderse
conscientemente; además, puede informar sobre la pronunciación de algunos segmentos, lo que ayuda a recomponer la
forma fónica de un texto. Para facilitar su adquisición se necesita secuenciar la presentación de sus problemáticas
— grafías con distintos valores o el uso de la tilde y los signos de puntuación — a lo largo de los diferentes niveles
del currículo. No se puede reducir el trabajo sobre la ortografía a la corrección de errores, sino que se tiene que
incluir una reflexión sobre su relación con la pronunciación, tal como hacemos a lo largo de estas páginas.
Finalizamos con algunas propuestas para integrar la ortografía con la pronunciación en el aula de español como lengua
adicional.
Demotivation while learning Spanish pronunciation
Authors: Méndez Santos María del Carmen 
Published: November 2024

Abstract
Demotivation has recently become a focus of language learning research. This chapter explores the
underrepresented connection between demotivation and pronunciation instruction with the objectives of (1) assessing
the link between pronunciation teaching and demotivation, (2) identifying potential demotivating factors, and (3)
analyzing student feedback to offer pedagogical recommendations. Qualitative methodology, involving semi-structured
interviews with 40 adult students of Spanish as an additional language from diverse countries was used to achieve
these goals. The findings indicate that students wish to have pronunciation instruction and value-corrective feedback
that bridges the gap between their spoken and desired language skills, and that they prefer this feedback to be
supportive and kind.

Published: November 2024

Resumen
Este capítulo se centra en la enseñanza de la pronunciación a un grupo de estudiantes muy
específico: los hablantes de herencia, cada vez más presentes en las aulas de español como lengua adicional, pero con
unas necesidades diferenciadas del resto. A partir de diversas caracterizaciones de los hablantes de herencia, que a
menudo son considerados hablantes nativos o bilingües de español pero cuya competencia es variable, presentamos sus
necesidades educativas en el aula atendiendo específicamente a su pronunciación, que suele corresponder a una de las
diferentes variedades del español, y revisamos la investigación reciente al respecto. Igualmente, establecemos una
serie de consideraciones pedagógicas y buenas prácticas sobre la enseñanza de la pronunciación a hablantes de
herencia, y también su papel en las aulas mixtas con otros aprendices de ELE.
The classification of general affine connections in Newton–Cartan geometry: towards metric-affine Newton–Cartan gravity
Authors: Schwartz Philip K 
Published: November 2024

Abstract
We give a full classification of general affine connections on Galilei manifolds in terms of independently specifiable tensor fields. This generalises the well-known case of (torsional) Galilei connections, i.e. connections compatible with the metric structure of the Galilei manifold. Similarly to the well-known pseudo-Riemannian case, the additional freedom for connections that are not metric-compatible lies in the covariant derivatives of the two tensors defining the metric structure (the clock form and the space metric), which however are not fully independent of each other.
A magnetic pendulum for demonstrating Mathieu-type parametric resonance
Authors: Wang Qing , Zhu Xinyi , Shi Yujun 
Published: November 2024

Abstract
We describe a magnetic pendulum apparatus designed for studying and demonstrating Mathieu-type parametric resonance. The apparatus features a T-shaped rigid arm with a neodymium (NdFeB) magnet bob, suspended by double V-shaped thread suspensions. It is parametrically driven by an alternating uniform magnetic field produced by Helmholtz coils. The pendulum is structurally simple and easy to implement, and its parameter-driven mechanism is transparent in terms of physics. The use of electromagnetic driving allows for precise control over both the frequency and amplitude of parameter modulation, enabling quantitative studying on parametric resonance. We have observed the first and second instability region of parametric resonance. We also theoretically analyze the impact of non-uniformity in the Helmholtz coils’ magnetic field on the pendulum motion, revealing that the non-uniformity can significantly alter the pendulum’s nonlinearity, influencing both the magnitude and the sign of the coefficients of the nonlinear terms. However, under the parameters of our experimental setup, the nonlinearity effect is mainly manifested in large swing angle motions. For small swing angle within 5°, the impact of magnetic field non-uniformity on parametric resonance is negligible. The experiment reported here is appropriate for undergraduates to carry out experimental research, helping them develop a more intuitive and quantitative understanding of parametric resonance.

Published: November 2024

Abstract
The thermal properties of interfaces in nanomaterials are critical for various technological applications, including thermal management in electronic and photonic devices, thermoelectric conversion and thermal insulation. Recent advancements in numerical simulation tools (the non-equilibrium Green’s approach, the Boltzmann transport equation and the Monte Carlo method, molecular dynamics simulations) have significantly enhanced our understanding of phonon transport and scattering processes in nanomaterials. These advances have led to the discovery of new thermal interfacial materials and enabled precise modulation of phonon thermal conductance to achieve desired thermal performance. This review summarizes recent research progress in interface thermal transport, focusing on intriguing heat phenomena such as finite size effect and phonon coherent property. Additionally, it discusses strategies for modulating thermal conductance through disorder and roughness. Finally, the review proposes the opportunities and challenges associated with modulating interface thermal transport.

Published: November 2024

Abstract
The yield point marks the beginning of plastic deformation for a solid subjected to sufficient stress, but it can alternatively be reached by x-ray irradiation. We characterize this latter route in terms of thermodynamics, structure and dynamics for a series of GeSe3 chalcogenide glasses with different amount of disorder. We show that a sufficiently long irradiation at room temperature results in a stationary and unique yielding state, independent of the initial state of the glass. The glass at yield is more disordered and has higher enthalpy than the annealed glass, but its properties are not extreme: they rather match those of a glass instantaneously quenched from a temperature 20% higher than the glass-transition temperature. This is a well-known, key temperature for glass-forming liquids which marks the location of a dynamical transition, and it is remarkable that different glasses upon irradiation head all there.
Thermal nonreciprocity tuned by wrinkle patterns in graphene
Authors: Li Bohan , Ji Qingxiang , Zhang Qi , Wang Changguo , Kadic Muamer 
Published: November 2024

Abstract
Thermal nonreciprocity are typically realized by using nonlinear heat conductivity, external field bias or spatiotemporal modulation of thermal parameters, but these methods require specific material properties or accurate modulation means. Low-dimensional materials like graphene provides a platform to engineer heat transport characteristics at the molecular level. Here, by simply tuning graphene’s wrinkle morphology, the approach to generate nonreciprocal heat transfer is reported, which applies to both static and dynamic heat signals. Such nonreciprocity is attributed to the tunable responses of thermal conductivity on both temperatures and wrinkles. Phonon density of states of the wrinkled graphene exhibit distinct spectra, especially at the low frequency (around

17

THz

), which results in reduced temperature-sensitivity of thermal conductivities and eventually induces thermal nonreciprocity. The findings provide insights into the physics of thermal transport in wrinkled graphene, and paves a new avenue for mechanically modulating thermal nonreciprocity. Our method to obtain thermal nonreciprocity is reversible, tunable and controllable, meanwhile remains structural integrity, which benefits functional applications such as heat management in electronics.
Design analysis and experimental verification of insulation blankets for civil aircraft nacelle and pylon
Authors: Gong Xingyu , Guo Junxian , Zhao Fei , Peng Sen 
Published: November 2024

Abstract
The nacelle and pylon structures of civil aircraft, due to their proximity to the engine, are significantly affected by the high-temperature components of the engine. To reduce the impact of high temperatures on the nacelle and pylon structures and their internal systems, insulation blankets are typically arranged on the inner side of the nacelle fan cowl, the inner side of the core cowl, and the bottom area of the pylon to decrease the thermal transfer effect from the high-temperature components of the engine and the hot air inside the core compartment to the nacelle and pylon structure. This paper mainly describes the structural design method and requirements for the nacelle pylon insulation blanket, and through thermal analysis theoretical calculations, the temperature changes on the cold side of the insulation blanket at different hot sides are derived. The results are compared with the insulation test results of the insulation blanket test pieces, further verifying the insulating performance of the blanket. In addition, environmental qualification tests were conducted on the insulation blanket test pieces, and insulation tests were re-performed on the test pieces after environmental testing, demonstrating the reliability of the nacelle and pylon insulation blanket design.

Abstract
Gold mill tailings (GMT) are waste from gold mill processing plants usually collected and stored in tailings storage facilities (TSF) and left for years in many abandoned mines in the world. GMT is in large amounts and contains high concentrations of chemicals and compounds that may harm human lives and the ecosystem if not well-maintained. A characterization study is conducted on GMT from a small-scale mill processing plant in Agusan del Sur, Philippines, and its potential utilization as an additive to sand and cement in making cement-stabilized products is also evaluated. The elemental and oxide composition, the presence of free and total cyanide, and particle size analysis were determined. Different proportions of gold mill tailings, cement, and sand were prepared and tested for compressive strength and water absorption. The results showed that the GMT contained some potentially valuable elements like tin, zinc, and europium. GMT also contains potentially hazardous elements like lead (663ppm), arsenic (157ppm), and mercury (17ppm). The free cyanide in the effluent is also found at 1.9 ppm. These elements and compounds are potentially hazardous in case of tailings seepage or overflow to groundwater and neighboring agricultural lands. The evaluation of cement-stabilized samples shows that the GMT from the study area can be utilized as an additive to cement and sand in the production of cement-stabilized products however it must be properly treated and handled to ensure the safety of workers. The TCLP result showed that the product is non-toxic and non-reactive. The construction and proper maintenance of a TSF for small-scale gold milling plants in the study area is recommended to prevent environmental, health, and safety risks.
Production of nitrogen-free syngas (H2 + CO) from CO2 and NH3
Authors: Keller Martin 
Published: November 2024

Abstract
Towards the goal of carbon neutrality, future chemical production could utilize captured CO2 as a carbon source instead of fossil carbon from petroleum or natural gas. However, the production of chemicals from CO2 is highly energy-intense. The required energy could be imported to Japan in the form of hydrogen. However, the long-distance transport of molecular hydrogen is challenging. NH3 has recently emerged as the most promising molecule for long-distance hydrogen transport and storage. The use of imported NH3 as an energy vector to realize carbon recycling in the Japanese chemical industry is promising. Syngas (H2+CO) is an important intermediate in the production of chemicals and fuels from CO2. Hydrogen is required not only as a constituent of syngas, but also as a reductant of CO2. If hydrogen is imported in the form of NH3, conventionally, NH3 would be cracked to H2 and N2, the product gases and unconverted NH3 separated, and CO/syngas then be produced through the reverse water gas shift reaction (RWGS). This conventional pathway is energy-intense and requires many unit operations. Here a novel process to produce nitrogen-free syngas directly, without producing molecular H2 first and without any dedicated gas separation steps is presented. This is realized by a using a metal oxide bed material that is active for catalytic cracking of NH3, as well as able to transport oxygen through a redox reaction in a newly designed process. This leads to an inherent separation of N2. This process, referred to herein as “NH3-RWGS” has the potential to decrease costs and increase efficiency of syngas production from CO2 and NH3.

Published: November 2024

Abstract
As the Philippine bioethanol industry concluded its first decade, it is in due time to assess whether the objectives of the Biofuels Act of 2006 (Republic Act No. 9367) are being met. Specifically, the law aims to reduce the country’s dependence on oil importation, mitigate toxic and greenhouse gases (GHGs), and promote the use of biofuels from indigenous resources to boost the country’s rural economy, by mandating biofuels blending to fossil-based fuels for transport use. This study examined the contribution of seven bioethanol production systems to the country’s climate change mitigation efforts by assessing the environmental impacts, particularly the carbon footprint and GHG emission reduction potential of each bioethanol distillery through life cycle assessment (LCA). Results of the environmental impact assessment revealed that the weighted average carbon footprint of the seven bioethanol production systems is at 1,415.66 gCO2e L−1, which ranges from 287 to 1,726 gCO2e L−1, translating to an average GHG reduction potential of 47.54% or an average avoided GHG of 268,091.15 tons CO2e yr−1 for CY 2019-2020. With the environmental hotspots identified, recommendations were made to improve the distilleries’ carbon footprints, and a sensitivity analysis was conducted to quantify the benefits from the recommended strategies. By applying all strategies, the average GHG reduction potential of the seven bioethanol production systems can get as high as 85.63%, which can be translated to an average avoided GHG of 482,933.91 tons CO2e yr−1.
Production characteristics in initial pyrolysis of lignin based on reactive molecular dynamics simulations
Authors: Kameda R , Sakurai Y , Hiratsuka M , Kobayashi J 
Published: November 2024

Abstract
Carbonization, direct liquefaction, and gasification, which are based on pyrolysis reactions, have been proposed as efficient technologies for energy recovery from biomass resources. However, modeling pyrolysis reactions of biomass with complex molecular structures is challenging, and numerical analysis methods that consider product compositions have not yet been established. In this study, molecular dynamics simulations were performed using LAMMPS, with the force field parameterized using ReaxFF. A molecular model based on Adler softwood lignin was created. The atomic trajectories were analyzed to identify the products of the pyrolysis process, and changes over time in inorganic gas, organic gas (C1-C4), light tar (C5-C14), heavy tar (C15-C39), and char (C40+) during the initial pyrolysis of lignin were investigated. The distribution of compositions formed and the formation behavior of typical low-molecular-weight components (such as formaldehyde and methanol) and inorganic gases from lignin were evaluated. The characteristics of the products in the initial pyrolysis of lignin, as analyzed from the molecular dynamics simulations, were based on the functional groups in the molecular model of lignin. Furthermore, similarities with the product compositions identified in experiments were also confirmed.
Investigation of the influence of fluorine on metal elution from cathodic active material liberated from spent lithium-ion batteries with a focus on the underwater electrical pulse method

Published: November 2024

Abstract
As a promising candidate to separate the cathode materials and aluminum foils, the underwater electrical pulse method is an environmentally friendly method that can effectively liberate cathodic active material in a very short time. However, performing the electric pulse separation in aqueous media may cause the release of fluoridated elements, which may come from fluoridated components formed during battery cycles or due to the remaining electrolyte within the cathode particles. Thus, the purpose of this work is to study the solution obtained after pulse discharge in terms of fluoridated entities, to understand their effect on the elution of active cathodic materials. Herein, to investigate the potential source of F and its possible effects on metal extraction, leaching experiments were conducted in the presence of different fluoride concentrations with a solid/liquid ratio of 0.5g/L under circumneutral pH conditions (pH range: 5.7-7.5) using a spent nickel-cobalt-manganese lithium battery sample liberated by N-Methyl pyrrolidone. The results show that the amounts of F ions in solution increased with leaching time, with a maximum value close to 2.34 ppm F obtained after 2 h. It is worth noting that the presence of fluoride-ion can promote the elution of aluminum, as a maximum concentration of 1.85 ppm Al was observed at 2 h in the presence of 40 ppm F, whereas only about 0.32 ppm Al was detected in the case of fluoride-free solutions. Consequently, our results demonstrated that the amounts of transition metals (Ni, Mn, and Co) released towards liquid changed very little irrespective of the concentrations of dissolved fluoride, suggesting that the released F ions do not affect metals elution.
