Semi-embedded clauses in Aisi
Authors: Daniels Don 
Published: April 2024

Abstract
This paper examines a construction in Aisi (Trans New Guinea) which consists of a formally subordinate clause that
expresses asserted meaning. This construction is called ‘semi-embedding’. The construction is more restricted than subordinate
clauses, and serves a specific discourse function: it presents the information in the matrix clause as a surprising climax. The
paper argues that semi-embedding arose when the backgrounding function of subordinate clauses was extended to allow assertions to
serve as backgrounds for certain highlighted events. As this happened, the relationship between the semi-embedded clause and its
matrix became more coordinate, which allowed longer strings of semi-embedded clauses to occur in what is called disengagement
(Cristofaro 2016). Fully insubordinate clauses can then occur when the main clause
no longer has to be uttered. At this point, the foregrounded meaning that originally centered on the main clause attached,
instead, to the newly insubordinate one.
Exploring linguistic competition in English derivatives ending in
‑ie and ‑o through a
cognitive-onomasiological approach
Authors: Tarasova Elizaveta , Fajardo José A. Sánchez 
Published: April 2024

Abstract
This study investigates the issue of linguistic
competition by analysing a dataset comprised of
‑ie/-o doublets, e.g.
kiddie/kiddo,
weirdie/weirdo. The analysis
is based on the key tenets of the onomasiological approach to
word-formation (Štekauer
1998) supplemented by the prototypical approach to affix
rivalry (Hamawand 2007).
The analysis aims to identify the nature of connections between the
conceptual, semantic, and onomasiological levels within
‑ie and ‑o paradigms taken
separately and whether these connections may play a role on the
onomatological level. The analysis of the data allows for
identifying four generic onomasiological models (i.e. quality,
patient, object, and action), in which the categories of quality and
patient convey the highest degree of competitiveness within the
evaluative domain of pejoration.
Diminutive formation in Modern Greek
Authors: Efthymiou Angeliki 
Published: April 2024

Abstract
The aim of this chapter is to investigate
variation in Modern Greek diminutive derivational means (affixes and
affixoids) by focusing on their selectional restrictions (e.g.
phonological, morphological, semantic) and their competition (e.g.
psilo.xondrós ‘dim.fat’ vs.
xondr.oúlis ‘fat.dim’). Given that the use of
all Greek diminutive morphemes (affixes or affixoids) is subject to
selectional restrictions, it is shown that the variation found in
diminutive derivational morphemes can be explained with reference to
their particular restrictions and their multifunctional character.
Furthermore, it is demonstrated that the domain of Modern Greek
diminutive morphemes can be thought of as a complex ecosystem
structured around a fairly complementary distribution (rather than
competition).
Passive without morphology
Authors: Sulemana Abdul-Razak 
Published: April 2024

Abstract
This paper examines the syntax of a novel construction I call Passive without Morphology (PwM) constructions in
Bùlì and the question of whether they have projected external arguments. The main proposal that I argue for is that PwM
constructions in all their occurrences possess projected implicit external arguments. The discussions presented in the paper
provide empirical as well as theoretical support for the classification of passives (Keenan
and Dryer 2007) and a theory of passives and implicit arguments (Collins
2021). This paper argues that the internal argument moves to Spec,TP in two steps: first, the VP moves into Spec,
VoiceP and from there the internal argument raises to Spec,TP (Collins 2005, 2021).
Spectral studies of thermally stable Dy3+/Sm3+ co-doped Li2Ba5W3O15 phosphors for warm white LEDs

Published: April 2024

Abstract
In the current study, a series of Li2Ba5W3O15: RE3+ (RE = Dy, Sm) [LBW:Dy3+/Sm3+] phosphors were prepared using a high-temperature solid-state method. X-ray diffraction, Scanning electron microscopy with energy-dispersive x-ray analysis scans showed that the crystal form was consistent with the standard LBW and comprised small irregularly shaped particles. Diffuse reflectance spectral (DRS) data was utilized to calculate the band gaps. Fluorescence study shows that LBW material doped with Dy3+ and Sm3+ yield distinct colors at 496 nm (blue) for Dy3+ and 582 nm (green-yellow), 612 nm (yellow), and 669 nm (red) for Sm3+ when excited by near-ultraviolet (336 nm) light. The observation of energy transfer between Dy3+ and Sm3+ ions play a role in modifying the luminescence of LBW:Dy3+/Sm3+ co-doped phosphors. With a constant excitation wavelength (λ
Ex), different levels of activator doping lead to a change in the emission colors from their neutral white light to a deep orange-red region for LBW:Dy3+/Sm3+ phosphors. The decay curves demonstrate a decrease in lifetime with an increase in the concentration of activator ions (Sm3+). For D3S5 phosphor, the temperature-dependent photoluminescence characteristics were analyzed under λ
Ex = 336 nm excitation. The results indicate excellent luminescence thermal stability with an activation energy of 0.16 eV at λ
Ex = 336 nm. With its low color-correlated temperature and good thermal stability, the prepared phosphor sample shows potential as a solid-state emitting phosphor that can be used with UV chip stimulation for warm white LED applications.
An improved positioning method based on compensation and optimization of ultra-wideband ranging results
Authors: Shi Zhiran , Wang Jie , Zeng Xianyang , Yang Hongli 
Published: April 2024

Abstract
Achieving precision in positioning under conditions of significant interference remains an unresolved challenge in research. This study introduces a low-cost ultra-wideband (UWB) distance compensation model that addresses electromagnetic wave loss in practical indoor settings. This paper employs kurtosis to detect non-line-of-sight environments, which are frequently induced by pedestrian movement. The Generalized Extreme Studentized Deviate algorithm is utilized to discern and eliminate outliers in ranging values and the Piecewise Cubic Hermite Interpolating Polynomial algorithm compensates for the eliminated data points. Finally, Kalman filtering is used to improve UWB ranging results, allowing for better error elimination and compensation. Experimental results demonstrate that our proposed algorithm has higher accuracy and the mean square error improvement ratio can reach more than 20% in dynamic positioning tests.

Abstract

Objective. Most deep neural network-based diffusion tensor imaging methods require the diffusion gradients’ number and directions in the data to be reconstructed to match those in the training data. This work aims to develop and evaluate a novel dynamic-convolution-based method called FlexDTI for highly efficient diffusion tensor reconstruction with flexible diffusion encoding gradient scheme. Approach. FlexDTI was developed to achieve high-quality DTI parametric mapping with flexible number and directions of diffusion encoding gradients. The method used dynamic convolution kernels to embed diffusion gradient direction information into feature maps of the corresponding diffusion signal. Furthermore, it realized the generalization of a flexible number of diffusion gradient directions by setting the maximum number of input channels of the network. The network was trained and tested using datasets from the Human Connectome Project and local hospitals. Results from FlexDTI and other advanced tensor parameter estimation methods were compared. Main results. Compared to other methods, FlexDTI successfully achieves high-quality diffusion tensor-derived parameters even if the number and directions of diffusion encoding gradients change. It reduces normalized root mean squared error by about 50% on fractional anisotropy and 15% on mean diffusivity, compared with the state-of-the-art deep learning method with flexible diffusion encoding gradient scheme. Significance. FlexDTI can well learn diffusion gradient direction information to achieve generalized DTI reconstruction with flexible diffusion gradient scheme. Both flexibility and reconstruction quality can be taken into account in this network.
M3D-K simulations of beam-driven instabilities in an energetic particle dominant KSTAR discharge
Authors: Zhang L.L. , Jhang H.G. , Kang J.S. , Sheng Z.M. , Fu G.Y. 
Published: April 2024

Abstract
We perform a systematic simulation study of energetic passing particle-driven instabilities in KSTAR using the kinetic-MHD hybrid code M3D-K. Linear simulation results show that the observed n = 1 mode in the early phase of the discharge is the low-frequency fishbone driven by energetic passing beam ions. The mode frequency computed is in a good agreement with the experimental measurement. Nonlinear simulations show that the frequency of the n = 1 mode jumps up to a higher value corresponding to the β-induced Alfvén eigenmode (BAE). In the later phase of the discharge, the simulated n = 5 mode is identified as a BAE in its linear phase. In the nonlinear phase, the n = 5 mode exhibits a similar frequency jump to a higher value of an energetic particle (EP) mode after mode saturation. Analysis of perturbed beam ion distributions in phase space shows that these new modes in nonlinear stages are driven by new resonances due to nonlinearly evolved beam ion distributions. Further simulations of a beam beta scan for the n = 5 mode show that the frequency jump disappears for a sufficiently small beam beta or beam ion drive. This result may explain the non-existence of frequency jump in the experiment. Finally, the impact of toroidal rotation on mode characteristics is investigated, showing that it has a marginal influence on EP driven modes.
Ambitious efforts on residual emissions can reduce CO2 removal and lower peak temperatures in a net-zero future

Published: April 2024

Abstract
Carbon dioxide removal (CDR) is expected to play a critical role in reaching net zero CO2 and especially net zero greenhouse gase (GHG) emissions. However, the extent to which the role of CDR in counterbalancing residual emissions can be reduced has not yet been fully quantified. Here, we use a state-of-the-art integrated assessment model to develop a ‘Maximum Sectoral Effort’ scenario which features global emissions policies alongside ambitious effort across sectors to reduce their gross GHG emissions and thereby the CDR required for offsets. We find that these efforts can reduce CDR by over 50% globally, increase both the relative and absolute role of the land sink in storing carbon, and more evenly distribute CDR contributions and associated side-effects across regions compared to CO2 pricing alone. Furthermore, the lower cumulative CO2 and nonCO2 emissions leads to earlier and lower peak temperatures. Emphasizing reductions in gross, in addition to net emissions while disallowing the substitution of less durable CDR for offsets can therefore reduce both physical and transition risks associated with high CDR deployment and temperature overshoot.

Published: April 2024

Abstract
The Chinese government attaches great importance to the construction of the National Forest City (NFC), aiming at creating a pleasant living environment beneficial for people’s health and well-being. This study aimed to estimate the effect of the NFC policy on the frequency of physical activity (PA) for people in mainland China. Using the nationally representative data from the China Family Panel Studies in 2010 and its follow-up in 2018, 17 704 participants aged 18 and older were analyzed in our study. We employed the two-way fixed estimator in the difference in difference setting to analyze the PA of the adults in the cohort with different development levels of the forest-environment construction measured by the number of NFCs, and explore the relative differences before and after the construction of NFC. Subgroup analysis of age group, gender and living areas and a series of robustness tests were further conducted. The mean age of 17 704 participants in 2010 was (45.03 ± 13.67) years old, 51.74% of which were female and 48.26% were male. DID results showed that after the construction of NFC, the frequency of PA increased by 1.35 (β = 1.35, 95% CI:0.73–1.98) per week compared to those in provinces without NFC after adjusting covariates. And the improving effect of the forest-environment construction on PA frequency was intensified in middle-aged and older adults aged 45 and above (β = 2.03, 95% CI:1.09–2.96), males (β = 1.26, 95% CI:0.39–2.12) and females (β = 1.49, 95% CI:0.58–2.40) and those living in urban areas (β = 1.29, 95% CI:0.57–2.00). Our findings showed that the forest-environment construction under the NFC strategy has a positive role in the PA of older adults, indicating the health-promoting effects of the national green low-carbon environmental strategy. Considering the heterogeneity, it is essential to promote the benefits of green exercise for young and rural adults.

Published: April 2024

Abstract
In high power density transmission systems, the friction and wear characteristic of copper based powder metallurgy materials is directly linked to working reliability. Moreover, these materials have frictional self-healing characteristic at the material interface. This paper focuses on exploring the healing mechanism of copper based powder metallurgy materials and conducts ‘damage-healing’ tests, proposing a method to characterize the self-healing characteristic. Subsequently, through comparative tests, the influence of temperature, speed, and pressure on the self-healing characteristics is analyzed. The results show that the increase in temperature reduces the furrow width and depth by 15.30% and 59.76%, respectively. Pressure has the greatest effect on surface roughness, reducing it by 67%. Meanwhile, this paper developed a PSO (Particle Swarm Optimization)-LSTM (Long Short-Term Memory) method to accurately predict the self-healing characterization parameters and self-healing time with small error (average 4.35%) and high correlation coefficient (R
2) (average 0.976). This study contributes to the development of interface repair technology for friction materials.
Dynamic response and roughness control of surface materials on TC4 titanium alloy subjected to laser shock wave planishing
Authors: Wu Lei , Dai Fengze , Wang Mengyue , Chen Xizhang 
Published: April 2024

Abstract
In this study, ABAQUS was used to predict the dynamic response of surface materials on TC4 titanium alloy during laser shock wave planishing (LSWP). The experiments were conducted to evaluate the simulations. The results indicate that during the initial stage of LSWP, the contact status between the contact foil and the micro-protrusion changes from the one-dimensional stress state to the one-dimensional strain state. This causes the high-amplitude tensile residual stress to converge at the center of the flattened micro-protrusion surface. When treating specimens with high surface roughness, the application of a thin contact foil can significantly lower the height of micro-protrusions and lift the bottom of micro-depressions. This improves the plastic flow of micro-protrusions and prevents the convergence of tensile residual stress. Using a thick contact foil can help extend the pressure pulse duration and prevent the overall surface profile subsidence when treating specimens with lower surface roughness. The outcomes of the experiment and the simulation agree rather well. Additionally, a thick contact foil can reduce the build-up of tensile residual stress by reducing the contact pressure.
ZrN doped with 3d transition metals: a computational investigation of main physical properties for high-temperature structural applications
Authors: Mnisi B O , Tibane M M 
Published: April 2024

Abstract
In the present study, ab initio density functional theory calculations were used to assess the effect of first-row transition metals (X = Sc, Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Zn) on the stability of Zr0.5N0.5 nitrides. Specifically, the structural, mechanical, and electronic properties were studied to evaluate their applicability in high-temperature structural applications such as coating. The heat of formation for all X-doped Zr0.5N0.5 ternaries were found to be lower than that of the undoped Zr0.5N0.5. Specifically, Mn-doped Zr0.5N0.5 was observed to be the most thermodynamically stable structure, due to its lowest heat of formation. The density of states for both the undoped and doped Zr0.5N0.5 nitrides indicated full metallic behavior and observed that doping with 3d-transition metals reduce the density of states at the Fermi energy, thereby enhancing the electronic stability. Furthermore, mechanical stability was observed in these nitrides with increased melting temperatures expect for Zr0.5N0.5 doped Ti. Since Zr0.5N0.5 doped with X is thermodynamically, electronically, and mechanically stable, they are deemed suitable for high-temperature structural applications especially Zr0.5N0.5 doped Mn.
Rapid shoaling of aragonite saturation horizon in the northern Indian Ocean
Authors: Sridevi B , Sarma V V S S 
Published: April 2024

Abstract
Anthropogenic carbon dioxide (CO2) penetrates up to 1000 m of water column in the Indian Ocean resulting in acidification and corrosion of aragonite skeletal material. The shallowest aragonite saturation horizon (ASH) was observed in the Bay of Bengal (BoB; 219 ± 10 m) within the tropical Indian Ocean. The ASH shoaled at the rate of 6.3 ± 5 and 4.4 ± 3 m yr−1 in the past four decades in the BoB and Arabian Sea respectively. As a result, an increase in total alkalinity (TA) was observed at the rate of 0.5 ± 0.3 and 0.25 ± 0.2 μmol kg−1 yr−1 at the depth of ASH in the BoB, and Arabian Sea respectively. While the shoaling rate of ASH remained the same in the Arabian Sea over the past four decades, in contrast, rapid shoaling was observed in the BoB in the recent decades due to higher accumulation of anthropogenic CO2 in the upper ocean associated with an increase in river discharge and decomposition of riverine organic matter. These two processes decreased the pH resulting in corrosion of aragonite skeletal material and increased TA at the depth of ASH in the BoB. Under a business-as-usual scenario, aragonite-secreting organisms will be seriously affected by the middle of this century in the BoB.

Published: April 2024

Abstract
This paper reports and benchmarks a new implementation of nuclear magnetic resonance shieldings, magnetizabilities, and J-couplings for molecules within semilocal density functional theory, based on numeric atom-centered orbital (NAO) basis sets. NAO basis sets are attractive for the calculation of these nuclear magnetic resonance (NMR) parameters because NAOs provide accurate atomic orbital representations especially near the nucleus, enabling high-quality results at modest computational cost. Moreover, NAOs are readily adaptable for linear scaling methods, enabling efficient calculations of large systems. The paper has five main parts: (1) It reviews the formalism of density functional calculations of NMR parameters in one comprehensive text to make the mathematical background available in a self-contained way. (2) The paper quantifies the attainable precision of NAO basis sets for shieldings in comparison to specialized Gaussian basis sets, showing similar performance for similar basis set size. (3) The paper quantifies the precision of calculated magnetizabilities, where the NAO basis sets appear to outperform several established Gaussian basis sets of similar size. (4) The paper quantifies the precision of computed J-couplings, for which a group of customized NAO basis sets achieves precision of ∼Hz for smaller basis set sizes than some established Gaussian basis sets. (5) The paper demonstrates that the implementation is applicable to systems beyond 1000 atoms in size.
A novel Zende’s-TOPSIS method towards estimation of measurement uncertainty in hole diameters
Authors: Zende Rohit V , Pawade Raju S 
Published: April 2024

Abstract
The ‘Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS)’ is one of the best methods for ‘Multi-Criteria Decision-Making’ and ‘Multi-Objective Optimization’. The traditional TOPSIS method determines the best alternative under fixed conditions. However, it cannot determine the best upper limit and lowest limit values. This work explains the detailed methodology of the newly developed Zende’s-TOPSIS method which was used to estimate the measurement uncertainty in hole diameters. Four identical holes and one center hole in an industrial component were measured to investigate measurement uncertainty. According to the experimental results, Zende’s-TOPSIS method performed better than the traditional TOPSIS method. The percentage improvement in the Zende’s-TOPSIS method over the traditional TOPSIS method ranges from 0.0209% to 0.3053%. Using Zende’s-TOPSIS method, the percentage maximum measurement uncertainty for four identical holes varies from 0.8067% to 1.0222%, whereas for the center hole, it varies from 0.5261% to 0.5576%. Similarly, the percentage minimum measurement uncertainty for four identical holes varies from 0.3839% to 0.6406%, whereas for the center hole, it varies from 0.4014% to 0.4041%. The proposed method is also capable of estimating the machined tolerances of the component, which ranges from 18.0772 mm to 18.1708 mm for four identical holes and 49.2215 mm to 49.2572 mm for the center hole. The proposed method can solve various ‘Multi-Objective Optimization’ problems.
