A cautious approach to spatial orientation in Tima
Authors: Alamin Suzan , Schneider-Blum Gertrud 
Published: January 2024

Abstract
This study investigates two subdomains within the
semantic field of space among the Tima in Sudan: first, topology (and
toponymy), and second, frames of reference. Like many European languages,
Tima uses adpositions to indicate a goal/location and a source. Furthermore,
Tima uses locative prefixes (remnants of a noun class system) to designate
an area. With respect to frames of reference, we show that Tima uses a mixed
system, availing of all major frames, i.e., absolute, intrinsic, and
relative. The data at our disposal suggests that mobility as well as the
shape of figure and ground play a role in the encoding of spatial relations
in Tima, a hypothesis which needs testing with more data.
Utu as epistemology and conviviality in Kiswahili
culture
Authors: Brühwiler Agnes , Hollington Andrea 
Published: January 2024

Abstract
Anthropological linguistics is essentially concerned with
language in/as cultural practices as they emerge and change through humans
living in communities. Yet the aspect of living together itself has rarely
been explicitly addressed from anthropological linguistic perspectives. In
our contribution, we aim to explore the concept of utu
(‘humanity’) in Kiswahili by looking at linguistic practices in different
domains. To show that utu can be regarded as an
epistemology and a way of knowing and mastering living together as humans,
we will look at language in unyago (coming-of-age rituals),
proverbs and sayings but also at grammatical features of Kiswahili. This
chapter thus investigates concepts of humanity at the intersection of
language and culture.
Kin-relational expressions of the Tima (Nuba Mountains, Sudan)
Authors: Veit Nataliya , Schneider-Blum Gertrud 
Published: January 2024

Abstract
Tima, a language of the Nuba Mountains in Sudan, is
severely endangered, as can be seen in many disappearing domains of the
lexicon. One domain that is still relatively strong pertains to kinship.
Continued use of this vocabulary can be linked to the high value still
placed on social accountability among relatives. However, other aspects
considered to be part of the handed-down social texture seem to be gradually
falling into oblivion. This contribution on the lexical expression of
kinship in Tima aims to describe the status quo concerning the structure of
kinship units, i.e., the clan system, as well as the lexicon of kin
relations. With regard to the latter, we also look at kin terms used in
referential practices beyond the narrow domain of kin relatedness.
Tail-head linkage in Upper Guinea Coast languages
Authors: Cobbinah Alexander 
Published: January 2024

Abstract
This paper draws attention to a phenomenon at the
intersection of pragmatics, discourse analysis and syntax known as tail-head
linkage (THL) in Baïnounk Gubëeher and other West African languages spoken
in Upper Guinea (Senegal, Guinea Bissau, Cabo Verde). THL is a discourse
feature common in narratives and procedural texts, whereby phrases or parts
of phrases are repeated in consecutive phrases to create discourse cohesion.
Largely absent from European languages, THL is common in languages of Papua,
Australia and the Amazon, but has not yet been described in depth for any
African or so-called Creole languages. However, these structures are well
attested in Atlantic languages spoken in the Casamance area and also in
various of the regional Portuguese based Creoles. As these languages are not
closely genetically related, THL is a good candidate for an areal feature.
Drawing on a corpus of transcribed texts in Baïnounk Gubëeher and Joola
Kujireray and Banjal as well as experimental data in those languages as well
as four varieties of Upper Guinea Creoles (Santo Antão, São Vicente,
Casamance, Bissau), the discursive function, frequency and the syntactic
strategies for the use of these structures are described and compared.
On politeness and taboo among the Zande
Authors: Pasch Helma , Gumekpala Faustin Dusa 
Published: January 2024

Abstract
Azande living in rural areas have to obey many rules of
behavior, many of which are determined by politeness or are rules determined
by taboos, which are often interrelated. Politeness rules concern behavior
towards other people, and they depend on age, social hierarchy and
in-law-relationships. If these rules are disrespected, offenses can be
corrected. Taboos, however, are absolute prohibitions with regard to certain
persons, places or phenomena, which are complied with by everybody. Neglect
of taboos may lead to sanctions which cannot be undone, such as hair turning
red or the body becoming uncontrollably obese. The impact of taboos is
stronger than that of politeness rules.
Indeterminate pronouns in Kaqchikel
Authors: Duncan Philip T. , Torrence Harold , Mateo Pedro Pedro 
Published: January 2024

Abstract
This paper investigates the morphology, syntax, and semantics of five non-interrogative constructions that involve
wh-expressions in Kaqchikel, a Mayan language of the K’ichean branch spoken in Guatemala. We focus on the properties of maximal
free relative clauses, existential free relative clauses, ever free relative clauses, free choice items and
negative indefinites. We show that the interpretive properties of these constructions are strikingly similar to those found in a
number of unrelated languages.
Unraveling the multifaceted nature of job satisfaction among migrant healthcare interpreters/translators
Authors: Phanthaphoommee Narongdej , Thumvichit Athip 
Published: January 2024

AbstractThis study employs Q methodology to analyze the job satisfaction of healthcare interpreters/translators who serve Myanmar migrant workers in Thailand. The unique working conditions imposed by the pandemic are addressed from the various perspectives of the interpreters and translators, who are also migrants. The participants (n = 26) were clustered into different groups based on their shared viewpoints on sources of job satisfaction. The findings confirm that job satisfaction among healthcare interpreters and translators is multifaceted and personal; they derive from interactions with other members of the interpreter’s immediate professional circle, confidence in one’s own inherent values, and an emotional urge to belong to their professional community, which is dominated by the host country’s citizens. This study concludes that recognizing and bolstering the commitments of healthcare interpreters and translators is vital for establishing work-life balance and should be supported by the state, particularly during times of crisis.
Spherically symmetric elastic bodies in general relativity
Authors: Alho Artur , Natário José , Pani Paolo , Raposo Guilherme 
Published: January 2024

AbstractThe purpose of this review it to present a renewed perspective of the problem of self-gravitating elastic bodies under spherical symmetry. It is also a companion to the papers (2022Phys. Rev.D105044025, 2022Phys. Rev.D106L041502) and (arXiv:2306.16584[gr-qc]), where we introduced a new definition of spherically symmetric elastic bodies in general relativity, and applied it to investigate the existence and physical viability, including radial stability, of static self-gravitating elastic balls. We focus on elastic materials that generalize fluids with polytropic, linear, and affine equations of state, and discuss the symmetries of the energy density function, including homogeneity and the resulting scale invariance of the TOV equations. By introducing invariant characterizations of physically admissible initial data, we numerically construct mass-radius-compactness diagrams, and conjecture about the maximum compactness of stable physically admissible elastic balls.

Authors: Dong Chao-Wei , Lee Kang-Hyuk , Na Jong-Hyun , Joo Dong-Hyun , Choi Jin-Ho , Park Woo-Tae 
Published: January 2024

Abstract
Microneedles can extract various analytics from the human body in a minimally invasive manner and provide real-time diagnosis, making microneedle-based point-of-care testing devices increasingly popular. In this paper, we propose a press-activated blood extraction system that integrates solid microneedles and 3D-printed blood collection devices for efficient blood extraction. The technology combines a solid microneedle array, a high-speed insertion mechanism, a negative pressure generating structure, and a blood reservoir containing lithium heparin anticoagulant into a compact, self-contained device. The device requires minimal training, as blood can be drawn with a simple finger push of the silicone chamber. This device is more convenient and less painful than finger sticks and venipuncture.

Authors: Yang Zhe , Li Mingchen , Wang Wanxia , Gong Jianhong , Sun Honggang , Sun Hui 
Published: January 2024

Abstract
Copper iodide (CuI) is an intrinsically transparent p-type semiconductor with a wide band gap of about 3.1 eV. In this work, Cu3N films were prepared as precursors through high-power impulse magnetron sputtering and then were solid-phase iodinated at room temperature for the preparation of transparent CuI films. Subsequently, transparent p-CuI/n-ZnO heterojunctions were fabricated wherein ZnO layers were deposited by radio frequency magnetron sputtering. After the properties are optimized by annealing, the heterojunctions exhibit significant rectification characteristics. The influence of annealing temperature on the electrical properties of the heterojunctions have been investigated. The optimal ideality factor of about 1.22 can be obtained with a rectification ratio of 1.05 × 105 after the heterojunctions annealing at 100 °C. This value is superior to most of the results reported in the literature. Meanwhile, the light-to-dark current ratio and the transmittance in the visible region of the heterojunction have also been studied. The light-to-dark current ratio is significant at 6.42 × 106. The average transmittance of the heterojunctions is 72.7%. These findings demonstrate the potential applications of CuI for optoelectronic devices and the promising prospects of p-CuI/n-ZnO heterojunction-based photodetectors and other optoelectronic devices.

Published: January 2024

Abstract
The detection of ultraviolet (UV) radiation holds significant importance in various fields. As the demand for superior detector performance grows alongside advancements in science and technology, there is a need for detectors with larger light-to-dark rejection ratios and lower standby power consumption. This paper presents the outstanding performance of the rare earth metal oxide Nd2O3 in broadband UV detection. With a wide forbidden band width of 4.6 eV, eliminating the requirement for additional filters, Nd2O3 emerges as an ideal material for broadband UV detectors. The device exhibits remarkable characteristics, including a dark current of only 1.66 × 10−11 A at a 5 V bias voltage, a light-to-dark rejection ratio of 1.33 × 103 at 280 nm and 15 μW cm−2, a responsiveness of 0.061 A W−1, and a detection rate of 4.7 × 1012 Jones. Furthermore, the performance of the device can be significantly enhanced through the formation of a heterojunction with TiO2. The heterojunction device exhibits a shortened response time of 78.64%, a reduced recovery time of 88.97%, and an increased light-to-dark rejection ratio of 2.75 × 103 at a 5 V bias voltage. This significant improvement in performance highlights the potential of the Nd2O3/TiO2 heterojunction in broadband UV detection.
Investigation of the dependence of temperature attenuation of the layered bio-tissue

Published: January 2024

Abstract
High-intensity focused ultrasound for solid tumor ablation is a noninvasive ultrasound hyperthermia technique wherein ultrasound is transmitted through multiple layers of biological tissues, focusing on the target area. The resulting heat accumulates in the target tissue, leading to irreversible cell death or protein necrosis, achieving tumor ablation. During treatment, the efficiency of acoustic energy converting to heat is closely related to temperature attenuation in the layered tissues. To obtain an accurate prediction of thermal damage, variations in the acoustic parameters should be measured at different temperatures. This study used two methods to induce heating to the tissues: the water heating method (WHM), which involves heat transfer from the outside to the inside, and the ultrasound heating method (UHM), wherein the heat source is located inside the tissue. The finite-amplitude insertion-substitution method was utilized to determine the attenuation coefficients of various bio-tissues such as porcine fat, muscle, and liver as the temperature increased. To mitigate the effects of viscous heating artifacts, the ‘wait then measure’ (WTM) thermometric approach was utilized using wire thermocouples to measure the temperature of the ultrasound-heated tissue. Experimental results demonstrate that the attenuation coefficient of bio-tissues varies with temperature under different heating methods. This study presents the variation in tissue attenuation using WHM at 5 MHz, while tissue categories using UHM are modeled with formulas at a frequency of 2 MHz.

Abstract
We report the most general classification of 3-3-1 models with

. We found several solutions where anomaly cancellation occurs among fermions of different families. These solutions are particularly interesting as they generate non-universal heavy neutral vector bosons. Non-universality in the standard model fermion charges under an additional gauge group generates charged lepton flavor violation and flavor changing neutral currents; we discuss under what conditions the new models can evade constraints coming from these processes. In addition, we also report the Large Hadron Collider~(LHC) constraints.
Noncentrosymmetric two-dimensional Weyl semimetals in porous Si/Ge structures
Authors: Lopes Emmanuel V C , Baierle Rogério J , Miwa Roberto H , Schmidt Tome M 
Published: January 2024

Abstract
In this work we predict a family of noncentrosymmetric two-dimensional (2D) Weyl semimetals (WSMs) composed by porous Ge and SiGe structures. These systems are energetically stable graphenylene-like structures with a buckling, spontaneously breaking the inversion symmetry. The nontrivial topological phase for these 2D systems occurs just below the Fermi level, resulting in nonvanishing Berry curvature around the Weyl nodes. The emerged WSMs are protected by C
3 symmetry, presenting one-dimensional edge Fermi-arcs connecting Weyl points with opposite chiralities. Our findings complete the family of Weyl in condensed-matter physics, by predicting the first noncentrosymmetric class of 2D WSMs.
GNSS blanket jamming classification algorithm based on spatial attention mechanism and residual shrinkage neural network
Authors: Lin Zijian , Zhuang Xuebin , Niu Ben , Zeng Kun 
Published: January 2024

Abstract
In the context of an increasingly complex electromagnetic environment, satellite navigation systems have become highly susceptible to jamming. Detecting and classifying jamming has thus become crucial for taking effective anti-jamming measures. This paper addresses the issue that the classification accuracy of blanket jamming declines drastically in low jamming-to-noise ratio (JNR) scenarios. To tackle this challenge, a novel algorithm is proposed that combines the spatial attention mechanism with a residual shrinkage neural network (RSN-SA) to classify ten types of blanket jamming, ranging from single jamming to convolutional compound jamming. Specifically, the proposed algorithm first employs the Fourier Synchrosqueezed Transform to extract time-frequency (TF) domain features from the original jamming signal, generating corresponding TF images. Then, the RSN-SA is employed to identify and classify these images effectively while minimizing the impact of noise-related features. This allows the main parts of the TF images to be focused on, resulting in higher recognition accuracy. Simulation results demonstrate that RSN-SA achieves close to 100% accuracy for six single blanket jamming signals. Moreover, compared with the other five algorithms, RSN-SA effectively enhances the classification accuracy of convolutional compound jamming signals in low JNR scenarios and improves the recognition stability in high JNR scenarios. Overall, the proposed algorithm provides a promising solution for classifying blanket jamming in satellite navigation systems with high accuracy and robustness.
Application of deep learning to fault diagnosis of rotating machineries
Authors: Su Hao , Xiang Ling , Hu Aijun 
Published: January 2024

Abstract
Deep learning (DL) has attained remarkable achievements in diagnosing faults for rotary machineries. Capitalizing on the formidable learning capacity of DL, it has the potential to automate human labor and augment the efficiency of fault diagnosis in rotary machinery. These advantages have engendered escalating interest over the past decade. Although recent reviews of the literature have encapsulated the utilization of DL in diagnosing faults in rotating machinery, they no longer encompass the introduction of novel methodologies and emerging directions as DL methodologies continually evolve. Moreover, in practical application, novel issues and trajectories perpetually manifest, demanding a comprehensive exegesis. To rectify this lacuna, this article amalgamates current research trends and avant-garde methodologies while systematizing the utilization of anterior DL techniques. The evolution and extant status of DL in diagnosing faults for rotary machinery were delineated, with the intent of providing orientation for prospective research. Over the bygone decade, archetypal DL theory has empowered the diagnosis of faults in rotating machinery by directly establishing the nexus between mechanical data and fault conditions. In recent years, meta learning methods aimed at solving small sample scenarios and large model transformers aimed at mining big data features have both received widespread attention and development in the field of fault diagnosis of rotating machinery equipment. Although excellent results have been achieved in these two directions, there is no review and summary article yet, so it is necessary to update the review literature in the field of fault diagnosis of rotating machinery equipment. Lastly, predicated on a survey of the literature and the current developmental landscape, the challenges and prospective orientations of DL in rotary machinery fault diagnosis are presented.

Published: January 2024

Abstract
Human-robot interaction is crucial for the future of smart factories and new industrial systems. Safety in robotics has always been a top priority, with external sensors being studied to construct safety perception systems for robots. This paper proposes an obstacle avoidance strategy based on an efficient distance estimation method using a vision sensor to address the challenge of robot occlusion. The method fuses depth images with a predefined robot skeleton model to estimate robot pose in real time, and uses the optimized potential field model to achieve full-body collision avoidance. Comparative experiments validate the efficiency of the proposed method, which represents a significant contribution to enhancing human–robot interaction and safety in industrial settings.
Preparation and properties of oxidized multi-walled carbon nanotube superhydrophobic composites modified by bio-fatty acids
Authors: Hao Xiaoru , Cheng Zhihao , Xie Jun , Zhang Yu , Zheng Haikun , Zhou Jiahui , Sheng Wei 
Published: January 2024

Abstract
In this paper, a preparation method of superhydrophobic composites of oxidized multi-walled carbon nanotubes modified by stearic acid (SA) is proposed. Hydroxylated multi-walled carbon nanotubes (HMWCNTs) were obtained by oxidizing multi-walled carbon nanotubes with potassium dichromate to give them hydroxyl groups on the surface. Subsequently, the carboxyl group in the SA molecule was esterified with the hydroxyl group on the HMWCNTs. SA molecules were grafted onto the surface of multi-walled carbon nanotubes. SA modified oxidized multi-walled carbon nanotubes (SMWCNT) superhydrophobic composites were obtained. The results show that the water contact angle (WCA) of superhydrophobic composites can reach up to 174°. At the same time, the modified nanocomposites have good anti-icing and corrosion resistance. After low temperature delayed freezing test, the freezing extension time of the nanocomposite film is 30 times that of the smooth surface. Under strong acid and alkali conditions, the superhydrophobic nanocomposites still maintain good superhydrophobicity. The nanocomposites may have potential applications in the preparation of large-scale superhydrophobic coatings.

Published: January 2024

Abstract
We report a study to improve the ternary oxide Ni3V2O8′s electrochemical energy storage capabilities through correct surfactanization during hydrothermal synthesis. In this study, Ni3V2O8 nanomaterials were synthesized in three different forms: one with a cationic surfactant (CTAB), one with an anionic surfactant (SLS), and one without any surfactant. FESEM study reveals that all the synthesized Ni3V2O8 nanomaterials had a small stone-like morphology. The electrochemical study showed that anionic surfactant-assisted Ni3V2O8 (NVSLS) had a maximum of 972 F g−1 specific capacitance at 1 A g−1 current density, whereas cationic surfactant-assisted Ni3V2O8 (NVCTAB) had the lowest specific capacitance of 162 F g−1. The specific capacitance and the capacitance retention of the NVSLS (85% after 4000 cycles) based electrode was much better than that of the NVCTAB (76% after 4000 cycles) based electrode. The improved energy storage properties of the NVSLS electrode are attributed to its high diffusion coefficient, high surface area, and enriched elemental nickel, as compared to the NVCTAB electrode. All these excellent electrochemical properties of NVSLS electrode indicates their potential usage in asymmetric supercapacitor application.
Existence and uniqueness of solutions to the Peierls–Nabarro model in anisotropic media
Authors: Gao Yuan , Scott James M 
Published: January 2024

Abstract
We study the existence and uniqueness of solutions to the vector field Peierls–Nabarro (PN) model for curved dislocations in a transversely isotropic medium. Under suitable assumptions for the misfit potential on the slip plane, we reduce the 3D PN model to a nonlocal scalar Ginzburg–Landau equation. For a particular range of elastic coefficients, the nonlocal scalar equation with explicit nonlocal positive kernel is derived. We prove that any stable steady solution has a one-dimensional profile. As a result, we obtain that solutions to the scalar equation, as well as the original 3D system, are characterized as a one-parameter family of straight dislocations. This paper generalizes results found previously for the full isotropic case to an anisotropic setting.
