Authors: Jahangard Mahdi , Xie Ying , Feng Yuanjun 
Published: February 2025

Abstract
This study provides an overview of the application of predictive and prescriptive analytics in seaport operations and explore the potential of integrating predictive outputs into prescriptive analytics to advance research in this field. A systematic review of 124 papers was performed to identify and classify key topics based on application areas, types of applications, and employed techniques. Our findings show a growing interest in developing either predictive or prescriptive analytics models to improve seaport operational efficiency. However, there is limited research combining predictive outputs with prescriptive analytics for data-driven decision-making. Additionally, the hybridization of machine learning and operations research techniques remains underexplored. One promising area is applying machine learning models, such as reinforcement learning, to solve optimization problems. Predictive maintenance and data-enabled operational control measures for port equipment and facilities are also highlighted as interesting future research areas.
A comparative analysis of the impacts of digital lifestyles on the physical, mental, and social health among older internet users
Authors: Wang Bin 
Published: February 2025

Abstract
The Internet has become integral to contemporary lifestyles. Drawing definitive conclusions about the impact of digital lifestyles on the health of older Internet users is challenging because of conflicting research findings. This study proposes the prismatic effects framework that demonstrates superior applicability to older Internet users in China. A nationally representative sample of Internet users aged 60 years or older (N = 2085) from the 2018 China Longitudinal Ageing Social Survey was used in the analyses. Latent class analysis was employed to identify digital lifestyles through ten activities, and the augmented inverse probability weighted model was adopted to explore the association of digital lifestyles with physical, mental, and social health among older Internet users. Meaningful digital lifestyles were identified as follows: low-activity (12.71%), high-activity (5.95%), leisure activity (33.67%), and social activity groups (47.67%). The low-activity group indicated better physical health than the social activity group (Average Treatment Effect (ATE) = −0.12, 95% Confidence Interval (CI) = −0.23, −0.01). The high-activity group had lower depressive symptoms (ATE = −1.51, 95% CI = −2.23, −0.80) than did the low-activity group. Moreover, the high-activity (ATE = −0.58, 95% CI = −0.95, −0.22) and leisure activity (ATE = −0.34, 95% CI = −0.62, −0.05) groups demonstrated lower loneliness than did the low-activity group. The low-activity group had a higher risk of friend isolation than did the social activity group (ATE = −0.17, 95% CI = −0.30, −0.05) but more community involvement than the high-activity group (ATE = −0.23, 95% CI = −0.38, −0.08). These findings support the prismatic effects framework and reveal that the health effects of digital lifestyles are multidimensional with different potential benefits and harms across health dimensions. The nature of digital lifestyles may be more critical than digital access from a health outcome perspective.

This study investigates the electronic structure of the vanadium-based kagome metal YV6Sn6 using magnetoresistance (MR) and torque magnetometry. The MR exhibits a nearly linear, non-saturating behavior, increasing by up to 55% at 35 T but shows no evidence of Shubnikov–de Haas oscillations. In contrast, the torque signal, measured up to 41.5 T, reveals clear de Haas–van Alphen (dHvA) oscillations over a wide frequency range, from a low frequency of Fα ∼20 T to high frequencies between 8 and 10 kT. Angular and temperature-dependent dHvA measurements were performed to probe the Fermi surface parameters of YV6Sn6. The dHvA frequencies display weak angular dependence, and the effective mass, determined by fitting the temperature-dependent data to the Lifshitz–Kosevich formula, is 0.097 mo, where mo represents the free electron mass. To complement the experimental findings, we computed the electronic band structure and Fermi surface using density functional theory. The calculations reveal several notable features, including multiple Dirac points near the Fermi level, flatbands, and Van Hove singularities. Two bands cross the Fermi level, contributing to the Fermi surface, with theoretical frequencies matching well with the observed dHvA frequencies. These combined experimental and theoretical insights enhance our understanding of the electronic structure of YV6Sn6 and provide a valuable framework for studying other vanadium- and titanium-based kagome materials.
Reproducibility, replicability, robustness, and generalizability in corpus linguistics
Authors: Flanagan Joseph 
Published: February 2025

Abstract
Establishing the credibility of scientific research involves several related but significantly different concerns.
One potential problem in surveying different approaches to these concerns is that of terminology, as some of the basic terms used
in the discussion — reproducibility, replicability, robustness, and generalizability — are often used in inconsistent or
contradictory ways. This paper proposes to resolve such confusion by providing a terminological framework for discussing what kind
of confirmation is necessary for a scientific study to be deemed credible. A study is said to be ‘reproducible’ if we can obtain
identical results by performing an identical analysis on identical data, ‘replicable’ if we can obtain consistent results using
the same analysis on different data, ‘robust’ if we can obtain consistent results from identical data using a different analysis,
and ‘generalizable’ if we can obtain consistent results from different data using a different analysis.
A unified semantic account of Mandarin ordinal phrases
Authors: Chen Yi-Hsun 
Published: February 2025

Abstract
Mandarin ordinal phrases demonstrate an ambiguity between a definite reading and an indefinite quantity reading,
first observed by Tsai (2011). However, contra Tsai
(2011)’s lexical-ambiguity view, this paper presents a compositionally unified semantic analysis of the ambiguity of
Mandarin ordinal phrases. Specifically, the ambiguity of Mandarin ordinals under discussion is derived from the semantic
application of type-shifting rules and the pragmatic restriction on the domain of the ordinal morpheme di (which
is reminiscent of the in-situ approach to the ambiguity of superlatives), coupled with the semantic requirements of
di; therefore, a unified semantics of the ordinal morpheme di is maintained under either
reading. Furthermore, this paper suggests two important felicity conditions in general on the use of an ordinal phrase in
discourse. Besides theoretical contributions, this paper also presents empirical discoveries showing that some generalizations in
Tsai (2011) are not entirely correct. For instance, it is false that all ordinal
phrases in Mandarin Chinese must denote a singular entity (contra Tsai
2011). Instead, the semantics of classifiers matters for the denotation of an ordinal phrase: a Mandarin ordinal phrase
can denote a plural entity when a group classifier is used. Furthermore, the presence of measure classifiers
or certain predicates such as sheng ‘give birth’ is not a reliable diagnostic for teasing apart the two readings;
the role of contexts and world knowledge in determining the (un)availability of a given reading is identified and discussed.
Finally, this paper illustrates how the proposed analysis explains three puzzling properties of Mandarin ordinal phrases: (a) why
the indefinite quantity reading is missing in the subject position; (b) why the indefinite quantity reading is missing when the
experiential aspect marker guo occurs; and (c) why an ordinal phrase with canonical sortal classifiers has to
denote a singular entity.
Pruning translation of logical and accidental polysemy in traditional Chinese medicine terminology
Authors: Hou Yuehui 
Published: February 2025

Abstract
Excessive and arbitrary polysemy within traditional Chinese medicine (TCM) terminology presents a notable challenge to both the intralingual standardization of TCM terms and the interlingual development of a TCM knowledge system. This article categorizes polysemy in TCM based on the origins and relationships of the various senses of a polysemous term: Inherent polysemy, where terms retain their ordinary senses; logical polysemy, which includes both ordinary and technical senses; and accidental polysemy, characterized by exclusively technical senses. For addressing logical and accidental polysemy, this article proposes “pruning translation,” a methodology in terminology translation that refines and aligns a term closely with its original form by reducing multiple senses to its most essential meanings for enhanced clarity and precision. Three approaches, namely “centralization” for an underspecification account, “aggregation” for an overspecification account, and “literal translation” for literalism, are employed to demonstrate the application of pruning translation. This is exemplified through an analysis of five polysemous TCM terms: mào (冒), qīng (清), mài (脉), guǐ tāi (鬼胎), and xià xiè (下泄). The rationale for pruning translation stems from two key aspects: Firstly, the generation of polysemy, highlighting the need to eliminate context-dependent, unrecognized, or superficial senses for accurate cross-lingual translation; secondly, the representation of polysemy, supported by psycholinguistic evidence indicating that multiple senses in one language can often be effectively represented by a single lexical form in another, facilitating the consolidation of senses into a unified translation. This proposed methodology of pruning translation represents an innovative approach in the translation of polysemous TCM terminology, contributing to the field of terminology translation.
Non-returning boomerangs: An engaging exercise in rotational dynamics
Authors: Denny Mark 
Published: February 2025

Abstract
A non-returning boomerang can fly straight for over one hundred meters, but only if torques with a horizontal component are eliminated by careful shaping of the airfoil. An actuator disk model predicts that non-returning boomerangs must have a negative lift coefficient at both ends, in marked contrast to the returning boomerangs. Stability conditions are examined. The analysis of these ancient hunting weapons is, for the physics student, an instructive exercise in rotation dynamics.
The evolution of the intrinsic defects and melt characteristic during the equal-diameter growth stage of Cz-Si

Published: February 2025

Abstract
In the Silicon single crystal grown by Czochralski (Cz) method, intrinsic defects can be divided into two groups, namely intrinsic point defects and grown-in microdefects. The former includes vacancy (V) and self-interstitial Si atom (I); while the latter, consisting of the crystal originated particles (COPs), B defects and bulk microdefects (BMDs), is formed by the aggregation of excess intrinsic point defects. In this paper, the evolution of intrinsic defects and thermal stress in crystal during the equal-diameter growth stage are solved within a two-dimensional axisymmetric steady-state global heat and mass transport model. With the increase of the crystal height, the strength and action range of tensile stress are enhanced in the crystal, companied by the intrinsic point defects transition from V-rich to I-rich. At the same time, the central region of the crystal contains larger COPs with low density and smaller BMDs with high density; the peripheral region is dominated by smaller COPs with high density, and larger BMDs with low density. A large number of B defects mainly gather at the top of the crystal with almost negligible size as crystal height reaches to 1000 mm. In addition, the corresponding melt flow structure, temperature, and oxygen concentration with different crystal heights are also simulated. The uniformities of temperature and oxygen distributions decrease with the decrease of the melt volume, and the solid-liquid (S-L) interface is more concave towards the melt with a slightly increased Vp/G. These results will provide a more thorough understanding of the thermodynamic mechanism in Si crystal growth and for the further optimization design.&#xD;
Existence of a ﬂat band in highly correlated metal BaCo2P2

Published: February 2025

Abstract
We report on the observation of a flat band situated at the Fermi level (E
F) along with the structural, electrical transport, and magnetic properties of BaCo2P2 that crystallizes in the ThCr2Si2-type body-center tetragonal structure. This compound has the largest inter-layer pnictide (Pn) distance d
Pn-Pn
as well as the largest c/a ratio among all the known ACo2
Pn
2 (A = alkaline earth metal) compounds, where a and c are the tetragonal lattice parameters. Hence, the magnetic and electronic properties of this compound are expected to have a quasi-two-dimensional character. Despite the evidence of the presence of sizable magnetic interactions, magnetic susceptibility χ(T) of BaCo2P2 does not show magnetic ordering down to 1.8 K. The material shows good metallic conduction with a large residual resistivity ratio ρ300 K/ρ1.8 K ≈ 70 and a Fermi liquid behavior at low temperature. Kadowaki-Woods ratio R
KW of BaCo2P2 suggests the presence of sizable electronic correlations within this system. Additionally, a large many-body enhancement of 2.3 of the experimental density of states D
γ(E
F) over the band-structure D
band(E
F) is inferred to arise from sizable electron-electron and/or electron-phonon interactions leading to a substantial deviation from the free-electron behavior.&#xD;

Abstract
As a quintessential electrostatic excitation micro electro mechanical system device, the capacitive micromachined ultrasonic transducers (CMUTs) is extensively utilized across medical, industrial, military and numerous other fields. To comprehensively analyze the fundamental properties of CMUTs, it is imperative to investigate their precise mechanical behavior under electrostatic forces. When the fringing field effect of the CMUT is ignored, this manuscript introduces the electromechanical coupling model of the partially center electrode-covered CMUTs (PCEC-CMUTs) to analyze its fundamental properties under nonlinear electrostatic forces for the first time. Utilizing the Ritz method, a novel segmentation function is employed to express the electrostatic deflections of the PCEC-CMUTs. Through the solution results of this model, fundamental performance parameters such as collapse voltage, electrostatic deflection and resonant frequency can be rapidly obtained. Subsequently, the finite element model (FEM) with COMSOL 6.1a is used to validate the theoretical model. The relative errors of electrostatic deflections and resonant frequency between the theoretical model and the FEM are controlled less than 5% in the region less than 95% of the collapse voltage, which proves the correctness of the theoretical model. These theoretical analyses are instrumental for the design and optimization of electrostatically actuated micro-devices such as CMUTs, and provide a theoretical foundation for establishing immersion equivalent circuits for PCEC-CMUT cells and arrays.
Quality-compliance validation system for individual calibration and testing events: Case study of primary calibration of reference photovoltaic devices
Authors: IGARI Sanekazu , Watanabe Hiroshi , Fujimoto Toshiyuki , Shirono Katsuhiro 
Published: February 2025

Abstract
For individual calibration and testing events, no third-party assessments are conducted on the validity of measuring instrument calibrations, personnel qualifications, or the appropriateness of measurement conditions in current calibration and testing practices, as is done during accreditation review audits. Since performing such assessments manually can be labour-intensive for human reviewers and prone to errors, we have developed a system for the automatic validation of digitized data, working alongside the current accreditation system. This system is designed for the documented records of the calibration of a reference photovoltaic (PV) device. The system incorporates three key functions: data packaging, automatic validation, and auditable log by the means of the blockchain system. Specifically, all data related to the calibration of an item is packaged by an application, the extracted data from the package is validated by programs, and the validation logs are stored securely without tampering. This system can support quality compliance in calibration and testing processes.
A map neuron with a hybrid ion channel and its dynamics
Authors: Song Xinlin , Wang Ya , Yang Feifei 
Published: February 2025

Abstract
The ion channel in neurons is the basic component of signal transmission in the nervous system. The ion channel has important effects on the potential of neuron release and dynamic behavior in the neural networks. Ion channels control the flow of ions into and out of the cell membrane to form an ion current, which makes the excitable membrane produce special potential changes and become the basis of nerve and muscle activity. The blockage of ion channels has a significant effect on the dynamics of neurons and networks. Therefore, it is a very meaningful study to study the influence of ion channels on neuronal dynamics. In this work, a hybrid ion channel is designed by connecting a charge-controlled memristor (CCM) with an inductor in series, and a magnetic flux-controlled memristor (MFCM), capacitor, and nonlinear resistor are connected in parallel with the mixed ion channel to obtain the memristor neural circuit. Furthermore, the oscillator model with a hybrid ion channel and its energy function are calculated, and a map neuron is obtained by linearizing the neuron oscillator model. In addition, an adaptive regulation method is designed to explore the adaptive regulation of energy on the dynamic behaviors of the map neuron. The results show that the dynamics of a map neuron with a hybrid ion channel can be controlled by parameters and external magnetic fields. This study is also used to research on synchronization between map neurons and collective behaviors in the map neurons network.

Abstract
The measurement of cosmic rays at energies exceeding
100 TeV per nucleon is crucial for enhancing the understanding of
high-energy particle propagation and acceleration models in the
Galaxy. HERD is a space-borne calorimetric experiment that aims to
extend the current direct measurements of cosmic rays to unexplored
energies, such as protons exceeding one PeV. The payload is
scheduled to be installed on the Chinese Space Station in 2027. The
primary peculiarity of the instrument is its capability to measure
particles coming from all directions, with the main detector being a
deep, homogeneous, 3D calorimeter. The active elements are read out
using two independent systems: one based on wavelength shifter
fibers coupled to CMOS cameras, and the other based on photo-diodes
read-out with custom front-end electronics. A large calorimeter
prototype was tested in 2023 during an extensive beam test campaign
at CERN. In this paper, the performance of the calorimeter for
high-energy electron beams, as obtained from the photo-diode system
data, is presented. The prototype demonstrated excellent
performance, e.g., an energy resolution better than 1% for
electrons at 250 GeV. A comparison between beam test data and
Monte Carlo simulation data is also presented.

Abstract
Mimicking bone remodeling scaffolds were developed as supportive biomaterials to promote tissue formation at defect sites in osteoporosis. Scaffolds made of polyvinyl alcohol (PVA) were mixed with varying weight ratios of silk fibroin (SF) and a phytoactive compound-based soy protein isolate (SPI); PVA30SF, PVA10SF20SPI, PVA20SF10SPI, PVA30SPI. PVA was used as control. These components were mixed into aqueous solution and crosslinking with EDC before freeze thawing and freeze drying, respectively. Then, the scaffolds were characterized at the molecular level using FTIR and their morphology was observed using SEM. Physical properties including swelling and degradation were tested, as well as mechanical properties like stress-strain behavior and modulus. The biological performance of the scaffolds was evaluated through osteoblast cell culturing, assessing cell viability, proliferation, ALP activity, calcium content, and calcium deposition. The results demonstrate that the scaffolds with both SF and SPI had greater molecular mobility of –OH, amide I, II, and III groups, compared to the scaffold with only SF or SPI. These scaffolds also displayed larger pore sizes. Scaffolds with both SF and SPI showed higher swelling and degradation rates than those with only SF or SPI. Additionally, they exhibited better cell viability and calcium deposition, along with increased cell proliferation, ALP activity, and calcium content. Notably, the scaffold with a higher amount of SPI, PVA10SF20SPI, exhibited the most suitable performance for enhancing cell response, thereby promoting bone formation. This scaffold is proposed as a supportive biomaterial to be incorporated with plates and screws for bone fixation at defect sites in osteoporosis.&#xD;
