Directed high-energy infrared laser beams for photovoltaic generation of electric power at remote locations
Authors: Soref Richard , De Leonardis Francesco , Daligou Gerard , Moutanabbir Oussama 
Published: April 2024

Transferring energy without transferring mass is a powerful paradigm to address the challenges faced when the access to, or the deployment of, the infrastructure for energy conversion is locally impossible or impractical. Laser beaming holds the promise of effectively implementing this paradigm. With this perspective, this work evaluates the optical-to-electrical power conversion that is created when a collimated laser beam illuminates a silicon photovoltaic solar cell that is located kilometers away from the laser. The laser is a CW high-energy Yb-doped fiber laser emitting at a center wavelength of 1075 nm with ∼1 m2 of effective beam area. For 20 kW illumination of a solar panel having 0.6 m2 of area, optical simulations and thermal simulations indicate an electrical output power of 3000 W at a panel temperature of 550 K. Our investigations show that thermo-radiative cells are rather inefficient. In contrast, an optimized approach to harvest laser energy is achieved by using a hybrid module consisting of a photovoltaic cell and a thermoelectric generator. Finally, practical considerations related to infrared power beaming are discussed and its potential applications are outlined.
Pronoun shifts in political discourse
Authors: Phanthaphoommee Narongdej , Munday Jeremy 
Published: April 2024

Abstract
This article examines the English translations of former Prime Minister Prayut Chan-o-cha’s statements on the
international stage and the shifts in the first-person pronoun. Looking at interpersonal positioning through a systemic functional
linguistic lens, we found that the translations underline the explicitness of agency, highlighting the variation of stylistic
choices and interplay with source-text politics. The shifts come with a modified degree of willingness, a more active agency, an
increase in the modality of inclination, and more force in attitude. These interpersonal overtones largely contribute to recasting
the image of the Thai government to ensure its legitimacy, promote national unity, and appeal to the international community.
These crafted translated texts seem to hone the leader’s public persona in front of global audiences by continuing to enhance the
country’s reputation, thereby maintaining the speaker’s dignity and prestige–an essential for the national leader’s image.
East Asian translations of Jean-Paul Sartre’s pre-1950 literary works
Authors: Yeung Sabrina Choi Kit 
Published: April 2024

Abstract
Starting from his first appearance in an East-Asian literary magazine and ending with his last works to be
translated before the decline of his popularity in Hong Kong and Taiwan during the Cold War, the period 1938–1975 saw extensive
translations of Sartre’s literary works in East-Asia (Japan, Mainland China, Taiwan, Hong Kong). This study examines Sartre’s
literary works published before 1950, by which most of his renowned ones have been published in France. Divided into Japanese and
Chinese sections, it first elaborates on the state of translation of Sartre’s literary works in East Asia from 1938 to 1975 before
explaining the phenomenon of multiple translated versions and their differences. The focus then turns to two specific translation
cases, one in Japanese and another in Chinese, as examples to illustrate the relation between the vibrant scene of translation
attempts within the East Asian region and the wartime situations of the Second World War and the Cold War era. By conducting these
investigations, this essay aims to outline how, in Japan, the wartime situation impacted the practice and publication of
translations and how, in the case of China, the wartime experience of translators shaped their translation strategies and
interpretations regarding Sartre’s literary works.
The heart became hot

Published: April 2024

Abstract
This paper provides a comparative study of the conceptualization of ANGER in Dagbani and Dangme, classified as Mabia and Kwa languages respectively. We employ the Conceptual Metaphor Theory as an analytical tool for explaining the empirical facts on the conceptualization of anger in these languages. We show that the mental concepts of the Dangme and the Dagbani people reflect in their conceptualizations of ANGER. We demonstrate that although the two languages deploy varied body organs (especially the heart and stomach), to express anger, Dagbani tends to focus more on the use of the heart, the lungs and the chest to express anger, whereas Dangme uses the heart, stomach and the body or self. The two languages share a common conceptual metaphor of anger as ‘heat’ with other schematic nodes, such as ‘fire’, ‘fluid’ and ‘container’. We finally establish that although most of the expressions of anger in these two languages fit into cross-linguistic patterns, there are also salient cultural specifics that demonstrate how their physiological and experiential realities tend to play an important role in their conception of anger. Data for this study were collected from native speakers of these languages through spontaneous conversations as well as from literary works produced in the two languages under investigation.
To be or not to be
Authors: Guerberof-Arenas Ana , Toral Antonio 
Published: April 2024

Abstract
This article presents the results of a study focusing on the reception of a fictional story by Kurt Vonnegut
translated from English into Catalan and Dutch in three conditions: machine translated, post-edited, and human translated.
Participants (n = 223) rated the three conditions using three scales: narrative engagement, enjoyment, and
translation reception. The results show that human translation had higher engagement, enjoyment, and translation reception in
Catalan, compared to the post-edited and machine-translated translations. However, Dutch readers scored the post-edited
translation higher than the human and machine translation, and the highest engagement and enjoyment scores were reported for the
original English version. We hypothesize that when reading a fictional story in translation, not only are the condition and the
quality of the translation key to understanding its reception, but also the participants’ reading patterns, reading language, and,
potentially, the status of the source language in their own societies.
PTOLEMY's test of generalized neutrino interactions: unveiling challenges and constraints
Authors: Banerjee Indra Kumar , Dey Ujjal Kumar , Nath Newton , Shariff Saadat Salman 
Published: April 2024

Abstract
Unanswered questions surrounding neutrinos have motivated investigations into physics
beyond the standard model (SM) of particle physics. In particular, generalized neutrino
interactions (GNI) provide a broader framework for studying these effects compared to the commonly
studied non-standard neutrino interactions. These interactions are described by higher dimensional
operators while maintaining the gauge symmetries of the SM. Furthermore, the cosmic neutrino
background, a predicted component of the SM and standard cosmology, has yet to be directly
detected. To shed light on this elusive phenomenon, we conduct a comprehensive analysis of the
relevant GNI, specifically focusing on their implications for the proposed cosmic neutrino
detector PTOLEMY. We make an attempt to see the capabilities and the limitations of PTOLEMY in
sensing GNI while remaining optimistic regarding PTOLEMY's experimental resolution. These
interactions play a significant role in modifying the electron spectrum resulting from the capture
of cosmic neutrinos on radioactive tritium. This work also explores how the presence of these
interactions influences the differential electron spectrum, taking into account factors such as
finite experimental resolution, the mass of the lightest neutrino eigenstate, the strength of the
interactions, and the ordering of neutrino mass.
Parameter optimization of SQCC-CVQKD based on genetic algorithm in the terahertz band
Authors: Liu Chengji , Chao Yu , Wang Lu , Zhu Changhua , Li Qingshan 
Published: April 2024

Abstract
Recently, we proposed a continuous variable quantum key distribution (CVQKD) scheme based on simultaneous quantum and classical communication (SQCC) in the terahertz (THz) band. It performs classical modulation and quantum Gaussian modulation at the same coherent pulse at the sending end, and an amplifier is used to amplify and demultiplex the signal at the receiving end. However, the previous study set parameters based on prior knowledge which has significant limitations, and as the previous study showed, parameter selection is a crucial task that directly affects the performance of the system. In this paper, we use the genetic algorithm to optimize the parameter selection, and how the different conditions influence the optimal value of parameters is also analyzed. The simulation results show that the parameter optimized with the algorithm can make the scheme achieve a higher secret key rate which greatly improves the applicability of the SQCC scheme in the THz band. This work demonstrates the effectiveness of the scheme to construct wireless quantum communication networks.
On the Surface Helium Abundance of B-type Hot Subdwarf Stars from the WD+MS Channel of Type Ia Supernovae
Authors: Ji Rui-Jie , Meng Xiang-Cun , Liu Zheng-Wei 
Published: April 2024

Abstract
The origin of intermediate helium (He)-rich hot subdwarfs is still unclear. Previous studies have suggested that some surviving Type Ia supernovae (SNe Ia) companions from the white dwarf + main-sequence (WD+MS) channel may contribute to the intermediate He-rich hot subdwarfs. However, previous studies ignored the impact of atomic diffusion on the post-explosion evolution of surviving companion stars of SNe Ia, leading to the aspect that they could not explain the observed surface He abundance of intermediate He-rich hot subdwarfs. In this work, by taking the atomic diffusion and stellar wind into account, we trace the surviving companions of SNe Ia from the WD+MS channel using the one-dimensional stellar evolution code MESA until they evolve into hot subdwarfs. We find that the surface He-abundances of our surviving companion models during their core He-burning phases are in a range of

, which are consistent with those observed in intermediate He-rich hot subdwarfs. This seems to further support the notion that it is possible for surviving companions of SNe Ia in the WD+MS channel to form some intermediate He-rich hot subdwarfs.

Abstract

Objective. The extensive application of electroencephalography (EEG) in brain-computer interfaces (BCIs) can be attributed to its non-invasive nature and capability to offer high-resolution data. The acquisition of EEG signals is a straightforward process, but the datasets associated with these signals frequently exhibit data scarcity and require substantial resources for proper labeling. Furthermore, there is a significant limitation in the generalization performance of EEG models due to the substantial inter-individual variability observed in EEG signals. Approach. To address these issues, we propose a novel self-supervised contrastive learning framework for decoding motor imagery (MI) signals in cross-subject scenarios. Specifically, we design an encoder combining convolutional neural network and attention mechanism. In the contrastive learning training stage, the network undergoes training with the pretext task of data augmentation to minimize the distance between pairs of homologous transformations while simultaneously maximizing the distance between pairs of heterologous transformations. It enhances the amount of data utilized for training and improves the network’s ability to extract deep features from original signals without relying on the true labels of the data. Main results. To evaluate our framework’s efficacy, we conduct extensive experiments on three public MI datasets: BCI IV IIa, BCI IV IIb, and HGD datasets. The proposed method achieves cross-subject classification accuracies of 67.32

%

, 82.34

Authors: Cernat A , Negurescu N , Pana C , Nutu C 
Published: April 2024

Abstract
The use of alternative fuel may be a viable solution in order to ameliorate the engine performance especially in terms of pollutant emissions. Among the alternative fuels that can be use to fuel internal combustion engines hydrogen can be a viable alternative fuel especially due to the advantage of reducing the carbon emission at its use as alternative fuel even for partial substitution of classic fuel. Hydrogen has good combustion properties like higher Lower Heating Value, large inflammability limits, higher combustion speed, which may has a benefic influence on combustion process. The use of hydrogen to diesel engine bring few important issues that must be solved in order to assure the normal engine operation, starting with the fuelling system and engine with the control of the combustion process. The paper presents some results obtained during the theoretical modeling of the in-cylinder process at a diesel engine fuelled with classic fuel and hydrogen. The diesel fuel is energetically substituted by hydrogen in percent’s of 25% and 30%. The influences of hydrogen use on in-cylinder maximum pressure, maximum pressure rise rate, heat release rate, combustion temperature, indicated thermal efficiency and nitrogen oxides and smoke emission levels are shown and analyzed.
Versatile xanthan gum-based support bath material compatible with multiple crosslinking mechanisms: rheological properties, printability, and cytocompatibility study
Authors: Lai Guanyu , Meagher Laurence 
Published: April 2024

Abstract
Extrusion-based bioprinting is a promising technology for the fabrication of complex three-dimensional (3D) tissue-engineered constructs. To further improve the printing accuracy and provide mechanical support during the printing process, hydrogel-based support bath materials have been developed. However, the gel structure of some support bath materials can be compromised when exposed to certain bioink crosslinking cues, hence their compatibility with bioinks can be limited. In this study, a xanthan gum-based composite support material compatible with multiple crosslinking mechanisms is developed. Different support bath materials can have different underlying polymeric structures, for example, particulate suspensions and polymer solution with varying supramolecular structure) and these properties are governed by a variety of different intermolecular interactions. However, common rheological behavior can be expected because they have similar demonstrated performance and functionality. To provide a detailed exploration/identification of the common rheological properties expressed by different support bath materials from a unified perspective, benchmark support bath materials from previous studies were prepared. A comparative rheological study revealed both the structural and shear behavior characteristics shared by support bath materials, including yield stress, gel complex moduli, shear-thinning behavior, and self-healing properties. Gel structural stability and functionality of support materials were tested in the presence of various crosslinking stimuli, confirming the versatility of the xanthan-based support material. We further investigated the effect of support materials and the diameter of extrusion needles on the printability of bioinks to demonstrate the improvement in bioink printability and structural integrity. Cytotoxicity and cell encapsulation viability tests were carried out to confirm the cell compatibility of the xanthan gum-based support bath material. We propose and demonstrate the versatility and compatibility of the novel support bath material and provide detailed new insight into the essential properties and behavior of these materials that serve as a guide for further development of support bath-based 3D bioprinting.
Surface modification of a commercial bone plate (Ti6Al4V) implant for improved antibacterial and cytocompatibility via thermal dewetting of a silver thin film

Published: April 2024

Abstract
The high demand for bone grafts has motivated the development of implants with excellent osteogenic activity, whereas the risk of implant-associated infection, particularly given the rise of antimicrobial resistance, has compelled the development of implants with innovative antimicrobial strategies in which a small amount of bactericidal agent can effectively kill a wide range of bacteria. To induce antibacterial property, the surface of Grade-5 bone plate titanium implants used in clinical applications was modified using direct current (DC) sputter coating followed by thermal annealing. The 15 nm silver film-coated implants were thermally annealed in the furnace for 15 min at 750 °C. The modified implant surface’s antibacterial efficacy against Escherichia coli (E. coli), Staphylococcus aureus (S. aureus), Salmonella typhi, and Methicillin-resistant staphylococcus aureus bacteria has been assessed using a colony-forming assay. On the modified implant surface, the growth of E. coli and S. aureus bacteria is reduced by 99.72%, while highly drug-resistant bacteria are inhibited by 96.59%. The MTT assay was used to assess the cytotoxicity of the modified bone-implant surface against NIH3T3 mouse fibroblast cells. The modified bone-implant surface promoted fibroblast growth and demonstrated good cytocompatibility. Furthermore, the mechanical properties of the implant were not harmed by this novel surface modification method. This method is simple and provides new insight into surface modification of commercial metallic implants to have effective antibacterial properties against various classes of bacteria.
Self-aligned, inkjet-printed resistors on flexible substrates with excellent mechanical stability, high yield, and low variance

Published: April 2024

Abstract
Resistors are basic yet essential circuit components that must be fabricated with high precision at low cost if they are to be viable for flexible electronic applications. Inkjet printing is one of many additive fabrication techniques utilized to realize this goal. In this work, a process termed self-aligned capillarity-assisted lithography for electronics (SCALE) was used to fabricate inkjet-printed resistors on flexible substrates. Capillary channels and reservoirs imprinted onto flexible substrates enabled precise control of resistor geometry and straightforward alignment of materials. More than 300 devices were fabricated using poly(3,4-ethylene dioxythiophene):poly(styrene sulfonate) (PEDOT:PSS) as the resistive material and silver as the electrode material. By varying PEDOT:PSS ink formulation and resistor geometry, resistances spanning from 170 Ω to 3.8 MΩ were achieved. Over 98% of devices were functional and the relative standard deviation in resistance ranged from 3% to 18% depending on resistor length and ink composition. The resistors showed no significant change in resistance after 10 000 cycles of bend testing at 1.6% surface tensile strain. In summary, this work demonstrated a fully roll-to-roll compatible process for inkjet printing resistors with superior properties.

Abstract
Water management plays a key role in ensuring optimum polymer electrolyte fuel cell (PEFC) performance, and flow field design can influence the ability of a cell to balance maintaining hydration, whilst avoiding flooding and cell failure. This work deepens the understanding of water evolution in different PEFC flow channel designs, namely single serpentine (SS), double serpentine (DS) and parallel, using our novel high-speed neutron computed tomography method. We developed our previously-reported method by introducing continuous cell rotation, enabling 18 s per tomogram during 1 h holds at 300, 400 and 500 mA cm−2. The volume of water evolved in the cathode, membrane electrode assembly and anode was quantified, and key mechanisms for water droplet formation in the different flow channel designs were elucidated. The parallel flow field design had the poorest water management, with 47% of the cathode flow channel becoming filled after 1 h at 400 mA cm−2. This significant flooding blocked reactant sites and contributed to unstable cell performance and, ultimately, cell failure at higher current densities. The SS cell displayed the best water management, with only 11% of the cathode channel filled with water after 1 h at 500 mA cm−2, compared with 28% of the DS cathode channel. 3D visualisation and analysis of droplet behaviour elucidated how water ‘slugs’ in the SS were removed in the gas stream, whereas three of the four parallel cathode flow channels became entirely filled with water plugs, blocking gas flow and exacerbating cell flooding. The new insights gained here are expected to extend to novel flow field designs and image-based models, with the use of operando neutron CT demonstrated as a powerful technique for both visualising and quantifying water management in operating PEFCs, as well as deepening the knowledge of droplet behaviour in different flow field types.

Abstract
Amid the growing interest in triboelectric nanogenerators (TENGs) as novel energy-harvesting devices, several studies have focused on direct current (DC) TENGs to generate a stable DC output for operating electronic devices. However, owing to the working mechanisms of conventional DC TENGs, generating a stable DC output from reciprocating motion remains a challenge. Accordingly, we propose a bidirectional rotating DC TENG (BiR-TENG), which can generate DC outputs, regardless of the direction of rotation, from reciprocating motions. The distinct design of the BiR-TENG enables the mechanical rectification of the alternating current output into a rotational-direction-dependent DC output. Furthermore, it allows the conversion of the rotational-direction-dependent DC output into a unidirectional DC output by adapting the configurations depending on the rotational direction. Owing to these tailored design strategies and subsequent optimizations, the BiR-TENG could generate an effective unidirectional DC output. Applications of the BiR-TENG for the reciprocating motions of swinging doors and waves were demonstrated by harnessing this output. This study demonstrates the potential of the BiR-TENG design strategy as an effective and versatile solution for energy harvesting from reciprocating motions, highlighting the suitability of DC outputs as an energy source for electronic devices.
