Usage-based constructionist approaches and large language models
Authors: Goldberg Adele E. 
Published: August 2024

Abstract
The constructionist framework is more relevant than ever, due to efforts by a broad range of researchers across
the globe, a steady increase in the use of corpus and experimental methods among linguists, consistent findings from laboratory
phonology, neuroscience, sociolinguistics, and striking progress in transformer-based large language models. These advances
promise exciting developments and a great deal more clarity over the next decade. The constructionist approach rests on two
interrelated but distinguishable tenets: a recognition that constructions pair form with function at varying levels of specificity
and abstraction, and the recognition that our knowledge and use of language are dynamic and based on language use.
Thewo Tibetan’s /ta33/ and /nə33/
Authors: Powell Abe 
Published: August 2024

Abstract
This paper has three aims. First, in its form, this paper uses a narrative style to overtly highlight the iterative process used to identify the meaning of the two suffixes in question. Second, this paper seeks to describe the intricate workings of two verbal suffixes in Thewo Tibetan. Finally, this paper makes a defense of why these two suffixes belong to the category of evidentiality. Thewo Tibetan is spoken in China on the Gansu-Sichuan border. The suffixes /ta33/ and /nə33/ appear either directly after action verbs, or directly after the progressive aspect marker. /nə33/ is used to express that the speaker has sensory information of their claim at the time of the speech act. The temporal nature of the evidence, whether it is sensory information of the act itself or of the results of the act, is determined in part by the semantics of the verb (telic vs non-telic). In contrast, /ta33/ is used to express that at the time of the speech act, the speaker no longer has sensory evidence (but formerly did) of the stated action. Based upon these observations, this paper argues that temporal space and verbal semantics are key to understanding the cognition which underlies interpreting /nə33/ and /ta33/. As such, this paper makes the following three contributions: (1) In its form it provides an anecdote of failures and success along the path to identifying the function and meaning of two evidential suffixes; (2) It introduces two suffixes of the hitherto un-described Thewo Tibetan evidential system; and (3) It gives an in-depth analysis of these suffixes and offers evidence to support the claim that they are evidential suffixes.
Fourier method for inverse source problem using correlation of passive measurements*
Authors: Triki Faouzi , Linder-Steinlein Kristoffer , Karamehmedović Mirza 
Published: August 2024

Abstract
We consider the inverse source problem for the time-dependent, constant-coefficient wave equation with Cauchy data and passive cross-correlation data.We propose to consider the cross-correlation as a wave equation itself and reconstruct the cross-correlation in the support of the source for the original Cauchy wave equation. Having access to the cross-correlation in the support of the source, we show that the cross-correlation solves a wave equation, and we reconstruct the cross-correlation from boundary data to recover the source in the original Cauchy wave equation. In addition, we show the inverse source problem is ill-posed and suffers from non-uniqueness when the mean of the source is zero and provide a uniqueness result and stability estimate in case of non-zero mean sources.
A Kirchhoff Migration scheme for elastic obstacle identification
Authors: Rabinovich Daniel , Givoli Dan 
Published: August 2024

Abstract
Kirchhoff Migration (KM), sometimes called Arrival (or Travel) Time Imaging, is a basic and popular imaging technique based on the arrival time of waves from given sources to given sensors. It is commonly used in the fields of underwater acoustics and solid earth geophysics, for both subsurface structure analysis and for identifying unknown local obstacles (scatterers) in the medium. The present paper concentrates on the latter application. For acoustics, the KM algorithm is extremely simple and efficient, although it usually produces a rather crude image, which is the reason for its use as the method of choice when high resolution is not needed, or as a fast technique to produce an initial guess for a more sophisticated imaging method. For elasticity, KM is much more involved, as the arrival-time algorithm is not obvious, mainly since there is more than one wave speed at each spatial point. In this paper, a new KM scheme is proposed for obstacle identification in an isotropic piecewise-homogeneous elastic medium. The scheme is based on measuring two quantities that are second-order operators of the displacement field, which are related to P and S waves, and applying the acoustic KM algorithm to each of them, with the appropriate wave speed. It is demonstrated numerically that the operator related to S waves results in very good identification in many cases. The fact that measurements based on the S-related operator are preferred over those based on the P-related operator is an empirical observation, and awaits full analysis, although a partial explanation is given here.

Published: August 2024

Abstract
The integration of an artificial protective coating into the Zn metal anode is considered as a highly efficient approach to minimize growth of Zn dendrites. The present study involves the design and synthesis of NiCo nanomaterials featuring a three-dimensional (3D) open structure and an abundance of active groups on their surface. Subsequently, NiCo nanomaterials are applied as a protective coating onto Zn foil to safeguard the Zn anode. The NiCo protective coating provides a rich zincophilic site, thus enhancing the stability of the electrode and effectively inhibiting Zn dendrite growth. Hence, the NiCo@Zn\\|NiCo@Zn symmetric cell with a lifespan up to 950 h at a current density of 2 mA cm−2. When paired with NH4V4O10, the full battery exhibits satisfied ultra-long cycle stability, maintaining good capacity retention after 3000 cycles at 10 A g−1. This work provides a new idea for the practical application of zinc ion batteries.

Published: August 2024

Abstract
The combination of heteroatoms self-doping and nano-hierarchical-pore structure is essential in improving the physicochemical performance of gravi-volumetric scale supercapacitors based on biomass-derived carbon. Herein, this study used aromatic bio-organic waste from nutmeg leaves (Myristica fragrans Houtt) as raw materials due to their abundant dopant and high-potential unique nano-pore structure. A series of novel treatments were carried out using KOH immersion approach and bi-atmospheric (in N2 and CO2) pyrolysis to ensure the presence of rich heteroatoms and a defined pore structure. The results showed that KOH ratio in bi-atmospheric pyrolysis played an important role in the production of self-dopant N, O, and P. In addition, significant morphological changes were observed after the production process. The optimized material prepared at a ratio of 500 mmol g−1 showed rich heteroatoms dopant with values of 19.53%, 15.81%, and 3.01% for N, P, and O, respectively. The surface transformation of the products showed a unique structure of nano-hollow-fiber with a size of 8–12 nm size and a well-matched micro-mesopores ratio (4:1). In the 2E-symmetric system, the working electrode exhibited a high gravimetric capacitance of 235 F g−1 at 1 A g−1 and 210 F g−1 at 10 A g−1 (in H2SO4 electrolyte). The resulting energy output was relatively high at 32.64 Wh kg−1 with increased power density (218 W kg−1), coulombic efficiency (92.67%), and capacitance retention (89.78%). The findings also showed that the products obtained had a volumetric capacitance of 256.30 F cm−3 and volumetric energy of 35.00 Wh l−1. Based on these results, the selection of natural materials as well as the application of KOH immersion approach and bi-atmospheric pyrolysis produced natural self-doped N, O, P carbon nano-hollow-fiber for boosting the gravi-volumetric behavior of supercapacitors.
Photoproduction of the X(3872) beyond vector meson dominance: the open-charm coupled-channel mechanism
Authors: Cao Xiong-Hui , Du Meng-Lin , Guo Feng-Kun 
Published: August 2024

Abstract
Hidden-charm exotic hadrons will be searched for and investigated at future electron–ion colliders. For instance, the X(3872) can be produced through the exclusive process γ
p → X(3872)p. The vector meson dominance model has been commonly employed in estimating the cross sections of such processes. However, the coupled-channel production mechanism through open-charm meson-baryon intermediate states may play a crucial role. To assess the significance of such contributions, we estimate the cross section of the γ
p → X(3872)p reaction assuming the coupled-channel mechanism. For energies near the threshold, the total cross section is predicted to be of tens of nanobarns for γ
p → X(3872)p, which can be measured at future experimental facilities. Furthermore, the open-charm coupled-channel mechanism leads to a distinct line shape of the total cross section that can be utilized to reveal the production dynamics.
The determination of coefficients for size specific effective dose for adult and pediatric patients undergoing routine computed tomography examinations
Authors: Sookpeng S , Martin C J 
Published: August 2024

Abstract
The effective dose resulting from computed tomography (CT) scans provides an assessment of the risk associated with stochastic effects but does not account for the patient’s size. Advances in Monte Carlo simulations offer the potential to obtain organ dose data from phantoms of varying stature, enabling derivation of a size-specific effective doses (SEDs) representing doses to individual patients. This study aimed to compute size-specific k-conversion factors for SED in routine CT examinations for adult and pediatric patients of different sizes. Radiation interactions were simulated for adult and pediatric phantom models of various sizes using National Cancer Institute CT version 3.0.20211123. Subsequent calculations of SED were performed, and coefficients for SED were derived, considering the variations in body sizes. The results revealed a strong correlation between effective diameter and weight, observed with size-specific k-conversion factors for adult and pediatric phantoms, respectively. While size-specific k-conversion factors for CT brain remained constant in adults, values for pediatric cases varied. When using the tube current modulation (TCM) system, size-specific k-conversion factors increased in larger phantoms and decreased in smaller ones. The extent of this increase or decrease correlated with the set TCM strength. This study provides coefficients for estimating SEDs in routine CT exams. Software utilizing look-up tables of coefficients can be used to provide dose information for CT scanners at local hospitals, offering guidance to practitioners on doses to individual patients and improving radiation risk awareness in clinical practice.

Published: August 2024

Abstract
The growth of two-dimensional van der Waals magnetic materials presents attractive opportunities for exploring new physical phenomena and valuable applications. Among these materials, Fe3GeTe2 (FGT) exhibits a variety of remarkable properties and has garnered significant attention. Herein, we have for the first time created a nanomesh structure—a honeycomb-like array of hexagonal nanopores—with the zigzag pore-edge atomic structure on thin FGT flakes with and without oxidation of the pore edges. It is revealed that the magnitude of ferromagnetism (FM) significantly increases in both samples compared with bulk flakes without nanomeshes. Critical temperature annealing results in the formation of zigzag pore edges and interpore zigzag-edge nanoribbons. We unveil that the non-oxide (O) termination of the Fe dangling bonds on these zigzag edges enhances FM behavior, while O-termination suppresses this FM by introducing antiferromagnetic behavior through edge O–Fe coupling. FGT nanomeshes hold promise for the creation of strong FM and their effective application in magnetic and spintronic systems.
Effect of carboxyl group on photoelectrochemical performance of TiO2 nanowire arrays for water splitting
Authors: Ding Yibo , Jiang Chenfeng , Sun Yi , Zhang Xiaoyan , Ma Xiaoqing 
Published: August 2024

Abstract
TiO2 is one of the most studied semiconductor materials for the photoelectrochemical water splitting to hydrogen production, but it only responds to ultraviolet light. The introduction of organic compound is one of the common means to expand the visible light response of TiO2. In this work, rutile TiO2 nanowire arrays (NWs) were grown on conductive glass by a modified solvothermal method using oleic acid as the key additive. The obtained TiO2 NWs are characterized using x-ray diffraction, x-ray photoelectron spectroscopy, infrared spectroscopy and electrochemical characterization. The results show that the carboxyl groups arising from oleic acid are chemically bonded with the TiO2 NWs in the form of chelating bidentate, which increases the visible light absorption range and active sites of TiO2, and reduces the transfer resistance between the photoelectrode and the electrolyte. The photocurrent density is doubled to 0.17 mA cm−2 at 1.23 V vs. RHE. This work provides a novel idea for the design of metal oxide semiconductor photoanodes by adsorbing organic compounds.
Topology-optimized photonic topological crystalline insulators with multiband helical edge states
Authors: Chen Yafeng , Lan Zhihao , Wang Hai-Xiao , An Liang , Su Zhongqing 
Published: August 2024

Abstract
Photonic topological crystalline insulators (PTCIs) with helical edge states provide an alternative way to achieve robust electromagnetic wave transport and processing. However, most existing PTCIs only involve a single topological bandgap, and generally support a pair of gapped helical edge states, restricting the scope of applications in various fields such as multiband waveguides, filters, and communication systems. Here, we design dual-band PTCIs, in which multiple helical edge modes appear within two distinct bulk gaps, for transverse electric (TE) and transverse magnetic (TM) modes, respectively, by introducing the topology optimization method into the photonic crystals with glide symmetry. For PTCIs with TE modes, the mismatched frequency ranges of edge modes hosted by two orthometric boundaries offer an opportunity to realize a photonic demultiplexer. For PTCIs with TM modes, we show the enhanced second harmonic (SH) generation through the coupling of multiband edge modes by matching the frequency ranges of edge modes within the first and second bandgaps to fundamental and SH waves, respectively. This work provides a new way for designing multiband PTCIs with helical edge states, having promising potentials in developing multiband topological photonic devices for both linear and nonlinear applications.
A new shifted generalized Chebyshev approach for multi-dimensional sinh-Gordon equation
Authors: Abd-Elhameed W M , Ahmed H M , Zaky M A , Hafez R M 
Published: August 2024

Abstract
The numerical treatment of multi-dimensional non-linear sinh-Gordon equations is the focus of this paper. We numerically solve the (1 + 1) and (2 + 1) sinh-Gordon equations using two collocation algorithms. We select the set of basis functions as a set of generalized Chebyshev polynomials (CPs), which we express as orthogonal combinations of CPs. We develop and utilize some formulas related to these polynomials to propose our numerical algorithms. Specific values for the high-order derivatives of the basis functions serve in the derivation of the two presented algorithms. Additionally, we provide an estimation of the basis functions used in the convergence analysis study. We follow the two collocation algorithms to transform the sinh-Gordon equations into non-linear equation systems, which any suitable solver can handle. We provide some examples and comparisons to confirm the effectiveness of our presented algorithms.
Boosting photocatalytic stability: hydrophilic Sr-doped ZnO thin films prepared via the SILAR method for enhanced performance over multiple cycles

Published: August 2024

Abstract
This study deals with the synthesis and characterization of Sr-doped ZnO thin films with different concentrations (1, 3, 5, and 7 wt%) using the SILAR method (Successive Ionic Layer Adsorption and Reaction). The main objective is to evaluate the effectiveness of the films as photocatalysts for the degradation of methylene blue under natural sunlight conditions. X-ray diffraction analysis confirms the polycrystalline nature of the films, with the crystallite size increasing with increasing Sr doping along the (100) plane. Morphological changes on the film surfaces are revealed by scanning electron microscopy and correlate with the increasing Sr content. Energy dispersive x-ray spectroscopy (EDX) confirms that there are no impurities in all films. 3D surface topography shows that higher Sr doping leads to an increase in average roughness and root mean square (Rq) values. Measurements of the water droplet contact angle (WDCA) indicate the hydrophilicity of the surface. Optical analysis shows that the absorption capacity of the films increases with Sr doping and shifts slightly towards longer wavelengths. Additionally, the band gap energy (Eg) shows a linear increment with higher Sr dopant concentrations. The unique contribution of this work lies in the careful investigation of the photocatalytic degradation of methylene blue using Sr-doped ZnO films as photocatalysts under natural sunlight. In particular, the films doped with 5 wt% Sr show exceptional performance, achieving degradation rates of 94.82%, 94.61%, and 93.48% for the first, second, and third cycles, respectively. The novelty of these results lies in the successful synthesis of Sr-doped ZnO thin films by SILAR, the comprehensive characterization of their properties and the remarkable photocatalytic efficiency observed under real sunlight conditions. This work provides valuable insights into the potential application of these unique films for the efficient degradation of methylene blue, thus contributing to the further development of environmentally friendly photocatalytic materials.
General mass formulas for charged Kerr-AdS black holes
Authors: Gao Yunjiao , Di Zhenbo , Gao Sijie 
Published: August 2024

Abstract
It is well-known that the mass of a non-asymptotically flat spacetime cannot be uniquely defined. Some mass formulas for the Kerr-AdS black hole have been found and used in studying black hole thermodynamics. However, the derivations usually need a background subtraction to eliminate the divergence at infinity. It is also unknown whether the mass depends on the choice of coordinates. In this paper, we provide a more straightforward derivation for the mass formula, only demanding that the first law of black hole thermodynamics and Smarr formula are satisfied. We first make use of the Iyer-Wald formalism to derive a first law which avoids the divergence at infinity. Then we apply this formula to charged Kerr-AdS black hole expressed in the coordinates rotating at infinity. However, the first law associated with the timelike Killing vector field

∂

∂
t

is not integrable. Then, by making use of the gauge freedom of t, we find a favorite parameter

t
′

which just makes the mass integrable. Applying the scaling argument, we show that the mass satisfies the Smarr formula and takes the form M/Ξ3/2. Moreover, applying the conformal method with

∂

∂
t
′

, we obtain the same mass. By applying the first law to the coordinates which is not rotating at infinity, we find a preferred time T that makes the first law integrable and the mass is just the familiar mass M/Ξ2 in the literature. This mass is also confirmed by the conformal method. We find that the two mass formulas correspond to different families of observers and the preferred Killing times. So our work clarifies the ambiguities of mass in Kerr-AdS spacetimes.

Published: August 2024

Abstract
A promising solution to the energy issue and environmental deterioration is to use solar energy for the generation of hydrogen fuel (H2) as a clean source of energy on a large scale. The main goal of this work includes the development of ZnO-based photoelectrodes for effective photoelectrochemical (PEC) water splitting which enables the synthesis of H2 in an environmentally acceptable manner. This study focuses on the manufacture of ZnO thin films via the utilization of cost effective Successive Ionic Layer Adsorption and Reaction (SILAR) approach. Herein, pure and Cu-doped ZnO films at different doping ratios from 2 wt% to 6 wt% were effectively prepared. The examination of the produced films’ morphological, structural, optical, and chemical composition characteristics was conducted using atomic force microscopy (AFM), x-ray diffraction (XRD), UV–vis spectroscopy and energy dispersive x-ray spectroscopy (EDX) technique. For each sample, the PEC behaviours for green H2 production and the measurements acquired from impedance spectroscopy were also examined. In the PEC test, a 6% Cu electrode proved to have the best PEC performance whereas it exhibited a maximum current density of around 3.6 mA cm−2 in 0.3 M Na2SO4 electrolyte compared with the other electrodes.

Published: August 2024

Abstract
The present manuscript uses three Kudryashov-based methods to analytically inspect the class of Gerdjikov–Ivanov equations, which comprises the standard Gerdjikov–Ivanov equation and the perturbed Gerdjikov–Ivanov equation. Various optical solitonic solutions have been constructed. Certainly, as the reported solitonic structures happened to be exponential functions, diverse true solitonic solutions can easily be resorted to upon suitably fixing the involving parameters, including mainly the bright and singular solitons. Lastly, the study graphically examined some of the constructed structures, which were then found to portray some interesting known shapes in the theory of solitary waves and nonlinear Schrödinger equations. Additionally, the Kudryashov-index d has been noted to play a significant role in the propagation of complex waves in the nonlinear media described by Gerdjikov–Ivanov equations.
