This study investigates the translational and rovibrational energy of vacuum-ultraviolet (VUV) photodesorbed CO molecules from a CO polycrystalline ice (15 K) at ∼8 eV. The electronic excitation was produced by a pulsed VUV laser, and the photodesorption of CO molecules in their ground and first vibrational states was observed using resonance enhanced multiphoton ionization. Time-of-flight and rotationally resolved spectra were measured, and the kinetic and internal energy distribution were obtained. Vibrationally cold CO molecules were observed, with little energy in rotation and translation (≤300 meV). Ab Initio Molecular Dynamics (AIMD) simulations focusing on the description of the vibrational energy redistribution within an aggregate of 50 CO molecules were performed. The measured energy distributions are in very good agreement with those predicted by AIMD simulations. The rotational energy was found to slightly increase with translational energy, a trend also predicted by theory. This confirms the validity of the indirect desorption mechanism triggered by the excitation of CO in a high vibrational state.

We describe an efficient implementation of cluster perturbation and Møller–Plesset Lagrangian energy series through the fifth order that targets the coupled cluster singles and doubles energy utilizing the resolution of the identity approximation. We illustrate the computational performance of the implementation by performing ground state energy calculations on systems with up to 1200 basis functions using a single node and by comparison to conventional coupled cluster singles and doubles calculations. We further show that our hybrid message passing interface/open multiprocessing parallel implementation that also utilizes graphical processing units can be used to obtain fifth order energies on systems with almost 1200 basis functions with a 90 min “time to solution” running on Frontier at Oak Ridge National Laboratory.
Diversity, equity, and inclusion (DEI) of CLIL pedagogy and globalisation in Japan
Authors: Sasajima Shigeru , Kavanagh Barry 
Published: November 2024

Abstract
The paper discusses the potential of CLIL (Content and Language Integrated Learning) pedagogy in the current
practice of ELT (English Language Teaching) and the issues of global education from a viewpoint of DEI (diversity, equity, and
inclusion) in Japan. DEI into CLIL pedagogy ensures a variety of learning environments, appropriate CLIL learning, and a sense of
belonging. CLIL can also provide better ideas and resources to cultivate DEI. This paper therefore argues that CLIL pedagogy has
the potential to change and incorporate issues related to DEI. The Japan CLIL Pedagogy Association (J-CLIL) conducted a
questionnaire survey on CLIL and its sponsored events and activities in 2021. Results show that: (1) many teachers are not aware
of DEI; (2) their mindset can become gradually diverse; (3) current education lacks equity with respect to students; and (4)
inclusive education is still not satisfactory. Ensuring equity in DEI is crucial in the realm of CLIL teacher education.
Therefore, it is imperative for CLIL teacher education to be more attuned to DEI concerns to enhance the implementation of CLIL
practices effectively. The DEI process needs to be integrated into CLIL and globalisation within the Japanese context. For that
purpose, there needs to be more research and practice necessary to promote a CLIL type of languages-integrated learning, and this
paper argues that it can be done through the IMT (Integrated Multifunctional Teacher) development program in Japan.
When multiple route map designs are used by the same bus company
Authors: Yusrina Ilma , Ihara Hisayasu , Sunaga Shoji 
Published: November 2024

Abstract
This paper reports three separate studies. Study 1 consisted of route map observations; study 2 looked at map creator’s perspective, and study 3 considered user research and route map usage. It was observed that the route maps issued by one bus service provider in Fukuoka, Japan, have as many as 24 types of design variations. According to the route map creators, limited resources was the main reason for this practice. Route map usability testing, keyword sorting and interviews were conducted as part of a user-focused research. Map-reading tests revealed several practices that have a negative impact on user’s ability to read route maps, and the user research revealed that users prefer a unified design.
Visible light visual indoor positioning system for based on residual convolutional networks and image restoration
Authors: Chen Duiqiang , Qin Ling , Cui Lizhen , Du Yongxing 
Published: November 2024

Abstract
Visible light positioning (VLP) technology, with its advantages of low cost, strong anti-interference, and high precision, is widely researched and applied in various scenarios. In this paper, for the complexity of indoor environments, considering the problem of occlusion by various obstacles that may exist in indoor spaces, which may lead to incomplete imaging of complementary metal–oxide–semiconductor image sensors, a maximum gray value-based occlusion recovery and decoding scheme is proposed. This scheme effectively solves the problem of the visible light transmission channel being blocked and accomplishes LED-ID decoding. In addition, the overflow effect due to uneven light irradiation gathered in each pixel row affects the accuracy of decoding LED-ID, which in turn leads to poor positioning accuracy. In this paper, we propose to use an adaptive gamma correction method to eliminate the influence of the overflow effect and to improve the accuracy of decoding. In order to improve the positioning accuracy, a VLP algorithm based on a residual convolutional network (VisiResNet) is proposed to achieve high-accuracy positioning. The experimental results show that the average positioning error is 9.7 cm in the space of 9 m × 3 m × 3 m, and a decoding accuracy of 90% within 1.4 m is achieved in the face of different occlusion situations. The system can achieve centimeter-level positioning accuracy and meet indoor positioning requirements.
Thermal conductivity suppression in ZnO with AlZn2O4 and ZnP2 for thermoelectric applications
Authors: Hsin Cheng-Lun , Liu Yu-Ting , Tsai Yue-Yun 
Published: November 2024

Abstract
In this study, intrinsic ZnO powder was sintered and intercalated with particles. The resulting powder, along with a commercial p-type product, was consolidated into bulk materials, and their thermal conductivity was measured across a temperature range of 350 K–700 K. The thermal conductivity of the commercial p-type ZnO was found to be lower than that of intrinsic ZnO, attributed to controlled doping. Notably, our demonstration illustrated that the thermal conductivity can be reduced by a factor of 5–10 in the presence of AlZn2O4 and ZnP2 precipitates. This methodology presents a feasible approach for the future design of ZnO-based thermoelectric materials, particularly for thermal heat scavenging applications.
Exploring nonlocal correlations in arbitrarily high-dimensional systems
Authors: Barasiński Artur 
Published: November 2024

Abstract
The utilization of higher-dimensional systems holds promise for unveiling novel phenomena and enhancing the efficacy of practical tasks, such as entanglement-based quantum cryptography. However, detecting quantum correlations within qudit systems poses a formidable challenge. In this study, we delve into the intricacies of Bell’s nonlocality within higher-dimensional systems. We introduce a novel correlation function and leverage it to construct a family of Bell inequalities adapted for quantum systems of arbitrary dimensionality. By gauging the probability of local realism violation under random measurements as our primary metric, we explore the relation between pure state entanglement and nonlocality. Our findings align closely with predictions derived from the comprehensive polytope analysis via linear programming methods. While our focus predominantly centers on the two-qudit scenario, our methodology readily extends to the N-partite case, accommodating an arbitrary number of measurements per party.

Calculation Method for Bottomhole Flow Pressure in Co-layer Development of Multilayer Sandstone Reservoir
Authors: Tu Xingping , Liu Bin , Jia Duo , Li Liujie , Yin Jiawei , Lv Yuan 
Published: November 2024

Abstract
Accurately calculating the bottom hole flow pressure of a multi-layer stacked sandstone reservoir (hereinafter referred to as a multi-layer reservoir) is the basis for production splitting, oil well dynamic analysis, and reasonable work system determination in the development of multi-layer reservoirs. The bottomhole flow pressure model for single-layer oil reservoirs does not consider interlayer interference and the pressure drop caused by fluid flow in the wellbore, which doesn’t comply with the characteristics of multi-layer combined production, and the use of the maximum bottomhole flow pressure of the oil layer as the bottomhole flow pressure of each oil layer to adjust the production system of each oil layer doesn’t meet the requirements of other oil layer regulation. Firstly, starting from fluid mechanics, the frictional effect generated by fluid flow in the wellbore is systematically considered, and the relationship between wellbore frictional pressure drop and flow distance is established. The pressure drop formula generated by fluid flow in the wellbore is derived; Secondly, from the perspective of seepage mechanics, a formula for the bottom hole flow pressure of a single-layer reservoir was obtained. Combined with the expression for the difference in bottom hole flow pressure of each oil layer in the development of a multi-layer reservoir and the pressure drop expression for fluid flow in the wellbore, a bottom hole flow pressure model for each oil layer in the development of a multi-layer reservoir was established (hereinafter referred to as the multi-layer reservoir bottom hole flow pressure model). Substitute various parameters into the bottomhole flow pressure model of multi-layer oil reservoirs, and the error between the calculated values and the actual test values in the field is 0.10%~1.30%, with an average error of 0.82%, meeting the actual needs of the site. There is a significant difference in the bottom hole flow pressure values of each oil layer in the co production reservoir. The multi layer reservoir bottom hole flow pressure model can accurately calculate the bottom hole flow pressure of each oil layer, avoiding the inability to accurately adjust the production system of multiple oil layers for the same bottom hole flow pressure. It can provide technical support for the development of a reasonable drainage system for on-site co production oil wells and the realization of high and stable production.
Chinese astronomy in a world context
Authors: Cullen Christopher 
Published: November 2024

Abstract
This brief paper aims to indicate what the study of Chinese astronomy can add to our understanding of premodern astronomy in the wider world. Some aspects of Chinese astronomy enable us to perceive the interestingly contingent nature of much of what is often taken for granted about the way astronomy was done elsewhere, particularly in the premodern West. Two examples of East-West contact in astronomy are examined: exchanges with India, particularly in the Sui and Tang dynasties in the 7th and 8th centuries of the Common Era and contacts with astronomy from the 13th century CE Islamicate world. Finally the issue of the sphericity of the Earth is considered in a comparative context.
From time to spacetime to no time? The philosophy of relativity theory
Authors: Farr Matt 
Published: November 2024

Abstract
The shift from classical to relativistic physics significantly altered our conception of time. From a picture of space and time as autonomous concepts, and of reality as divided into moments of time, relativity theory introduced a picture of four-dimensional spacetime, and a ‘static’ or ‘block universe’ conception of time. This paper considers how exactly relativity theory clashes with our ordinary folk conception of time and what this ultimately means for how we should think about the nature of time.
Examples of entropy: from physics to nature
Authors: Sorguven Esra 
Published: November 2024

Abstract
This paper aims to give a short history of how the concept of entropy has been developed and how it is used today in diverse scientific disciplines in our quest for understanding ourselves and our environment. The first part of the paper gives a historical perspective, which starts with the invention of the first heat engines, continues with the verbal formulation of the laws of thermodynamics and ends with the formulation of the mathematical equations that tell the complete story of thermodynamics by describing the transport of mass, momentum, energy and entropy. The second part of the paper focusses on the use of entropy beyond heat engines and shows how entropy has influenced the thinking in scientific disciplines such as chemistry, biology, ecology, communication, economy and sociology. Both a historical summary and the examples presented in this paper are limited to within the domain of classical mechanics. Although entropy has ignited powerful ideas and has many uses in both relativistic and quantum mechanics, these are not within the scope of this paper.
What is a microscope? How the microscope has evolved over three hundred and fifty years
Authors: Peckham Michelle 
Published: November 2024

Abstract
The microscope is named from the Greek mikrós (small) and skopeîn (to see). The first light microscopes were described over three hundred and fifty years ago, building on the development of lenses for the telescope. The publication of Micrographia in 1665 popularised the microscope and yet its technological development only really took off in the 1800s in parallel with many other technological developments of the time. Key to building microscopes reproducibly was the theoretical understanding of how the image is formed in the microscope, developed by Ernst Abbe in the 1880s as part of his collaboration with Carl Zeiss. That eventually led to the standardisation of light microscopes with the help of the Royal Microscopical Society. The electron microscope was then invented in the 1930s, building on principles already uncovered for light microscopy. The microscope has continued to evolve to help us to see even smaller and smaller objects across the physical and life sciences, and it is a key tool for many scientists. This overview briefly summarises the development of the microscope from its early origins up to the present day.
Questioning Copernicus: cosmological principles on the eve of the Scientific Revolution
Authors: Tessicini Dario 
Published: November 2024

Abstract
This paper examines the issues arising from Nicolaus Copernicus’s heliocentric theory when it is considered in the context of historical controversies over the planetary order. It will investigate the terms of this issue as they were available to Copernicus, and will stress both continuities and discontinuities with Ptolemaic astronomy. The consequences of heliocentrism for celestial physics will also be considered. Some of the consequences are inherent to heliocentrism, although not all of them were accounted for in De revolutionibus and certain outcomes may have been unforeseen by Copernicus or discordant with his theory.
The unscientific history of cold fusion
Authors: Loughlin Michael 
Published: November 2024

Abstract
The announcement in March 1989 that sustained nuclear fusion reactions had been achieved in a table-top apparatus generated much publicity. The claims proved to be unfounded. How the evidence for these claims was presented provides a case study on unscientific methods and the breaching of scientific conventions. It will be shown how respect for these conventions is important to avoid similar fiascos.
Charge Parity Time (CPT) from the lens of an experimental physicist
Authors: Bowcock Themis 
Published: November 2024

Abstract
The domain of Charge Parity Time (CPT) symmetries has intrigued physicists for the better part of a century. Whilst the CPT theorem—a core principle asserting the combined invariance of charge conjugation, parity transformation and time reversal in quantum field theories—is foundational in modern theoretical physics, its implications are rooted deeply in the experiments that have confirmed or refuted our understanding. This paper delves into the world of CPT from an experimental physicist’s viewpoint.
Evolution of temperature measurement – beginnings, progress and prospects
Authors: Machin Graham 
Published: November 2024

Abstract
This paper starts by charting the development of temperature measurement from its beginnings with the thermoscope in the late 1500s through to liquid-in-glass and air thermometers in the 1600s and 1700s. The emergence of classical thermodynamics which put thermometry onto a sound physical footing is then briefly described as is the convergence of practical and thermodynamic thermometry in the late 1880s and early 1900s through the use of defined scales, which became the benchmark for reliable thermometry throughout the 20th century and beyond. Finally an outline of the kelvin redefinition in 2019 and its implications is given followed by a discussion of the prospect of driftless practical primary thermometry across a wide temperature range by the 2050s.
Design and experimental verification of composite stiffened panel under combined compression-shear loads
Authors: Wang Zhe , Wang Binwen , Bao Rui , Zhang Tiesong , Chen Xiangming 
Published: November 2024

Abstract
As an important part of the aircraft, the panel structure accounts for a large proportion of the building block verification system. The real stress state of the aircraft panel is usually not a uniaxial compression or shear, but a combined loading condition in service. In the past, box structure was usually tested for structure selection in the aircraft’s preliminary design phase, which was limited by immature panel test methods and equipment. At present, a general panel test system considering the actual load form and boundary conditions was independently developed by the Aircraft Strength Research Institute of China. A large-scale composite stiffened panel was designed and tested on this test system in this paper. The whole process of the test was monitored by digital image correlation technology and strain gauge measurement. The test process and results were detailed and analyzed. Experimental results show that the failure modes of stiffened panels under combined compression-shear loads include mainly three forms. The first is in the upper part of the panel, which shows a typical shear failure mode and tears along the shear loading direction of the specimen. The second is the fracture of the reinforced piece in the bottom right-hand corner of the specimen due to compression loads. The third form is the large-scale cracking at the junction of the reinforced piece and skin, which may be related to the coupling effect of combined loading.
Quantitative analysis of the impact of wrinkle defects on the strength of wind turbine blade main spars
Authors: Zheng Haocheng , Zhou Bo , Sun Ning , Zhang Lixin 
Published: November 2024

Abstract
Understanding the impact of wrinkle defects on the main spar of wind turbine blades is crucial for maintaining structural integrity and ensuring operational efficiency. This paper focuses on a quantitative analysis to determine how varying severities of wrinkles affect the structural strength of wind turbine blades. First, the study employed infrared nondestructive testing technology to inspect in-service wind turbine blades, identifying wrinkle characteristics. Based on these detected characteristics, finite element models were established to simulate the structural behavior. The Hashin failure criterion was employed to forecast the initiation of intralaminar damage, while a cohesive model with a bilinear traction-separation criterion was used to evaluate the interlaminar stress state and damage behavior of the laminates. Last, to achieve accurate simulation, a VUMAT subroutine was developed and executed in the ABAQUS software environment. The simulation results for ultimate tensile strength at different ratios of amplitude to wavelength were found to be within 10% of the experimental values. This level of accuracy underscores the reliability of the models used. The study revealed that as the ratio of amplitude to wavelength increases from 0.4 to 0.69, the ultimate tensile strength of the laminate structure decreases to one-fourth of its original value. This significant reduction highlights the severe impact that wrinkle defects can have on structural performance.
