Bugs in the system: the logic of insect farming research is flawed by unfounded assumptions
Authors: Biteau Corentin , Bry-Chevalier Tom , Crummett Dustin , Ryba Ren , St. Jules Michael 
Published: February 2025

Abstract
Insect farming is frequently proposed as an emerging industry that can improve the environmental and economic sustainability of the food system. However, existing research often overlooks significant challenges. In this article, we identify three bugs in the scientific literature on insect farming: (1) the overreliance on a handful of old studies when discussing environmental impacts; (2) the pervasive assumption that insect farms will utilise food waste; and (3) the reliance on theoretical price projections that do not hold up under commercial conditions. We then discuss how promising technologies, despite their theoretical benefits, often encounter social and material challenges in practice. Debugging the literature will involve producing more realistic life-cycle assessments, which will provide policymakers and industry with the data needed to make informed decisions for a truly sustainable food system.

Abstract
Control of gene expression is commonly mediated by distinct combinations of transcription factors (TFs). This cooperative action allows the integration of multiple biological signals at regulatory elements, resulting in highly specific gene expression patterns. It is unclear whether combinatorial binding is also necessary to bring together TFs with distinct biochemical functions, which collaborate to effectively recruit and activate RNA polymerase II. Using a cardiac differentiation model, we find that the largely ubiquitous homeodomain proteins MEIS act as actuators, fully activating transcriptional programs selected by lineage-restricted TFs. Combinatorial binding of MEIS with lineage-enriched TFs, GATA, and HOX, provides selectivity, guiding MEIS to function at cardiac-specific enhancers. In turn, MEIS TFs promote the accumulation of the methyltransferase KMT2D to initiate lineage-specific enhancer commissioning. MEIS combinatorial binding dynamics, dictated by the changing dosage of its partners, drive cells into progressive stages of differentiation. Our results uncover tissue-specific transcriptional activation as the result of ubiquitous actuator TFs harnessing general transcriptional activator at tissue-specific enhancers, to which they are directed by binding with lineage- and domain-specific TFs.
Current Age and Language Use Impact Speech-in-Noise Differently for Monolingual and Bilingual Adults
Authors: Bieber Rebecca E. , Phillips Ian , Ellis Gregory M. , Brungart Douglas S. 
Published: February 2025

Purpose:
Some bilinguals may exhibit lower performance when recognizing speech in noise (SiN) in their second language (L2) compared to monolinguals in their first language. Poorer performance has been found mostly for late bilinguals (L2 acquired after childhood) listening to sentences containing linguistic context and less so for simultaneous/early bilinguals (L2 acquired during childhood) and when testing context-free stimuli. However, most previous studies tested younger participants, meaning little is known about interactions with age; the purpose of this study was to address this gap.

Method:

Context-free SiN understanding was measured via the Modified Rhyme Test (MRT) in 3,803 young and middle-aged bilingual and monolingual adults (ages 18–57 years; 19.6% bilinguals, all L2 English) with normal to near-normal hearing. Bilingual adults included simultaneous (
n
= 462), early (
n
= 185), and late (
n
= 97) bilinguals. Performance on the MRT was measured with both accuracy and response time. A self-reported measure of current English use was also collected for bilinguals to evaluate its impact on MRT performance.

Results:
Current age impacted MRT accuracy scores differently for each listener group. Relative to monolinguals, simultaneous and early bilinguals showed decreased performance with older age. Response times slowed with increasing current age at similar rates for all groups, despite faster overall response times for monolinguals. Among all bilingual listeners, greater current English language use predicted higher MRT accuracy. For simultaneous bilinguals, greater English use was associated with faster response times.

Conclusions:
SiN outcomes in bilingual adults are impacted by age at time of testing and by fixed features of their language history (i.e., age of acquisition) as well as language practices, which can shift over time (i.e., current language use). Results support routine querying of language history and use in the audiology clinic.

Slow Philosophy in Destination Branding
Authors: Serdane Zanda 
Published: February 2025

Summary
This case study shows the application of slow philosophy in destination branding from the Destination Marketing Organisations’ (DMOs) perspective and illustrates how a national slow brand has been implemented at the local level. It is based on a qualitative study that used semi-structured in-depth interviews with DMOs’ representatives in Latvia where the slow philosophy was embedded in the national tourism brand “Latvia. Best enjoyed slowly” between 2010 and 2018. The case study demonstrates that while the slow brand has the potential to become iconic for a destination, the main challenge lies in its capability to represent a shared collective identity for larger destinations. Hence, the slow brand is more easily applied to cities, towns, or regions rather than nations. The case study provides practical recommendations for destination marketers willing to use the slow philosophy in destination marketing. The slow brand can be used in place branding if destination marketers can resolve its inclusivity and compatibility with other destination brands.

High-Quality Single-Pixel Imaging Based on Large-Kernel Convolution under Low-Sampling Conditions
Authors: Yuan Chenyu , Su Yuanhao , Wang Chunfang 
Published: February 2025

Abstract
In recent years, deep learning has been introduced into the field of Single-pixel imaging (SPI), garnering significant attention. However, conventional networks still exhibit limitations in preserving image details. To address this issue, we integrate Large Kernel Convolution (LKconv) into the U-Net framework, proposing an enhanced network structure named U-LKconv network, which significantly enhances the capability to recover image details even under low sampling conditions. Compared to conventional deep learning networks, the U-LKconv network can reconstruct images with higher Signal-to-noise ratio (SNR) and more detailed features at the same sampling rate. Specifically, at a sampling rate of 4.8%, our method achieves peak performance, with a PSNR of 28.41 dB and an SSIM of 0.852 during the tests, surpassing the performance of other comparison methods, the superiority of the proposed method is also validated in experiment. Additionally, our approach demonstrates a faster convergence rate compared to other deep learning networks, requiring only 30 epochs for network convergence. Consequently, U-LKconv network can be addressed as an exceptionally advantageous solution, not only in terms of image fidelity and robustness but also due to its significant computational efficiency, which makes it highly applicable in the field of low-sampling SPI and drives the practicalization of single-pixel imaging.

Abstract
We report observations of strong electron temperature profile stiffness in high poloidal beta (β_p~2) plasmas on EAST for the first time. Key features of this regime include: (1) Negligible contributions to stored energy and electron temperature from additional auxilliary heating power; and (2) a rapid increase of core broad-band turbulence (k_θ ρ_s~1-5,f~0-2000kHz) monitored by Collective Thomson Scatteing (CTS) diagnostic system. Notably, no significant increase in impurities or MHD activities are observed during this process. This strong stiffness can be interpreted as a nonlinear increase in turbulent thermal flux when temperature gradients exceed a critical threshold. Gyro-kinetic simulations show that Collisionless Trapped-Electron-Mode (CTEM) is responsible for the broad-band turbulence observed in the core, and the experimental electron heat fluxes could be well matched by the nonlinear electromagnetic simulations. This finding highlights the advantages of using CTS to detect microturbulence in the core of high-density plasmas, allowing for immediate identification of profile stiffness induced by turbulence.
Exploring changes in the static multipole polarizabilities of hydrogen atoms in Coulomb plus inverse square root potential
Authors: Xie Hongxia , Zhang Yongzhi 
Published: February 2025

Abstract
Polarizability is an important physical quantity that measures the electronic structure of an atomic molecule under the influence of an external electric field. Inspired by the work of A.M. Ishkhanyan and Pablo Serra, the authors have proposed to probe the atomic properties in the 1-5s state of free hydrogen atoms at criticality in Coulomb plus inverse square root potential. We have numerically calculated the polarizability with high accuracy in this work with the generalized pseudospectral method, which is a globally based configuration method with strong superiority in calculating the one-electron system. It allows numerical results to be obtained with high accuracy while ensuring the convergence of the results. Currently, the results of calculations of multipole polarizabilities of free hydrogen atoms in Coulomb plus inverse square root potential are all scarce, and most of them suffer from insufficient calculation accuracy. Therefore, it is expected that the results of this work could provide some accurate numerical results to fill the current data gap.
Analysis and research on the movement behavior of dust particles during powder feeding
Authors: Zhao Lijuan , Ma Ping , Gao Yu , Li Yongning 
Published: February 2025

Abstract
With the development of industry, the demand for powdered materials has gradually increased. Dust pollution generated during the loading and transportation of powdered materials has become increasingly severe. Silica powder is widely used in chemical production; however, a large amount of dust is generated during the feeding process of silica powder, which can lead to silicosis in workers exposed to it over long periods. To address the issue of substantial dust generation during the feeding of silica powder, this paper analyzes the mechanisms of dust formation and the forces acting on silica powder during the feeding process. Additionally, using the Euler-Lagrange (CFD-DPM) model, the internal flow field of the powder feeding process is simulated, examining the impact of mass flow rate and drop height on dust particle movement behavior. The research results show that dust is formed when the airflow resistance acting on powder particles overcomes their buoyant weight. As the mass flow rate increases, the amount of generated dust also increases. Analyzing dust movement behavior provides an in-depth understanding of dust dispersion patterns and dynamic characteristics, offering a scientific basis for industrial dust removal and reducing dust spread.
Study on the mechanical behavior and collapse resistance of double-casing under gypsum-salt layer
Authors: Wang Yang , Xiang Yi , Zhang Xuelun , Liu Siyan , Jing Jiajia , Chen Yan 
Published: February 2025

Abstract
There are abundant oil and gas resources under the gypsum-salt layer, but its creep characteristics can easily lead to casing damage and affect the normal development of oil and gas wells. However, double-layer casing technology shows potential in dealing with gypsum-salt layer creep, but the in-depth study of its prevention mechanism is insufficient. Given this, a two-dimensional finite element analysis model of the casing, cement sheath, and gypsum-salt layer is constructed in this paper, and the mechanical properties and compressive strength of double casing in the gypsum-salt layer are compared, and the internal mechanism of effectively preventing gypsum-salt layer creep is revealed. Based on the above model, the influence of casing eccentricity on mechanical behavior and extrusion strength of double casing is discussed. The results show that double-layer casing has a better control effect on gypsum-salt layer creep than single-layer casing because double-layer casing can reduce the stress and stress non-uniformity of casing. The influence of casing eccentricity on double-layer casing is negligible, the maximum equivalent stress change is less than 1%, and the extrusion strength only decreases by 0.26% ~ 0.38%.

Published: February 2025

Abstract
This paper is based on the measured data of the dual wave shock test of an electronic cabinet. Firstly, the dual wave shock test is introduced in detail, the measured data of each key point are analyzed, and the dynamic characteristics of the shock tester, fixture and equipment are studied. Then, the shock spectrum is transformed into the dual wave shock load curve of time history by empirical formula as the simulation input condition, and the modal analysis and impact response analysis of the fixture and the tested equipment are carried out by finite element analysis software. Finally, the structural design of the equipment is optimized several times to obtain the structural design that meets the dual wave shock test condition. This paper has a high reference value for the research ideas of similar equipment against dual wave shock.
Analysis and compensation of deformation impact on vehicle body platform
Authors: Liang Shen 
Published: February 2025

Abstract
To study the law of the impact of vibration impact on the vehicle body platform, a finite element analysis model of the system was established. Combined with the test and numerical simulation calculation, the impact of vibration impact was analyzed. It was pointed out that the elevation angle of tracking measurement was negatively and positively correlated with the platform shape variable of the vehicle body, the pointing of the Actuator was positively correlated with the shape of the vehicle body, and the elements of the Actuator were nonlinear to the deformation of the vehicle body. The error of actuator parameters is larger than that of vehicle shape variables. Based on obtaining the basic law of vehicle body deformation, the compensation method is studied, and a multi-dimensional spatial interpolation method is proposed to carry out a series of compensations for vehicle body deformation data, effectively reducing the impact of vibration. The simulation results show that the proposed method can significantly improve the system’s accuracy and has significant engineering application value.
Study on the bearing capacity of cold-formed thin-walled double-limbed steel lattice columns under eccentric compression about virtual axis with batten plate lacing
Authors: Anthony Muriki Barimba , Jin Lu , Liu Suchuan 
Published: February 2025

Abstract
Cold-formed thin-walled steel is among the materials most frequently used in the building, industry, and transportation fields because of the benefits it offers. These are lightweight, high-strength, environmentally friendly, and sustainable. To address the wide application requirements in practical engineering, the cross-section shapes of cold-formed thin-walled steel have diversified, and the stability issues of its components have always been key concerns in design and application. The behavior of these components is greatly influenced by the equivalent slenderness ratio. However, previous studies have not adequately addressed this issue; the literature lacks a limiting value for the slenderness ranges. This paper proposes a batten plate-laced cold-formed thin-walled double-limbed steel lattice column. Research on the effects of the component’s equivalent slenderness ratio, the cross-section of the primary and secondary hemming length, web width-to-thickness ratio, clear limb spacing distance, and eccentric distance on the lattice column’s eccentric compression performance were conducted. In the final step, the load-axial displacement curve, ultimate bearing capacity, and failure modes of the double-limb lattice column were obtained. The results showed that its eccentric compression performance worsened as the lattice column’s equivalent slenderness ratio increased. The failure mechanism of the latticed columns evolves from local buckling to a hybrid of global and local buckling, eventually developing into a predominantly global buckling failure.
Controlling bubbles position during the ice formation process
Authors: Yu Yingjiao , Kong Lingjie , Yu Yang 
Published: February 2025

Abstract
It is significantly important to make transparent ice blocks or design the microstructure of ice by understanding the mechanism of bubble formation during the ice formation process. A theoretical model has been established to relate the thickness of the bubble-free segment and the solidification rate. A series of ice formation experiments have been done with different solidification rates. The critical saturation ratio of industrial distilled water is calculated as 11.65 by the theoretical model, which is slightly smaller, by measuring the thickness of the bubble-free segment and solidification rate. The explicit expression of bubble-free distance agrees well with the experimental results and numerical solutions. Completely transparent ice blocks are made by controlling the solidification rate guided by the model. It helps to understand the reason why a layered pouring method can increase efficiency.

Authors: Guo Dongyun , Sha Guang , Lu Bowen , Lu Yuzhou 
Published: February 2025

Abstract
In this paper, the ultimate seismic capacity of a full reservoir basin impermeable panel dam is analyzed in depth from the aspects of dam slope stability, seismic residual deformation, panel stress, and geomembrane and joint deformation, in combination with conventional ultimate seismic indexes. The key parameters, such as minimum safety factor, cumulative slip, permanent deformation of dam body, panel stress, geomembrane tension, and joint dislocation under different seismic peak accelerations, were calculated using a finite element dynamic time course analysis. The results show that from the perspective of dam slope stability, the ultimate seismic capacity of the full reservoir basin impermeable panel dam is 0.40~0.50 g; from the perspective of dam body seismic subsidence rate, the ultimate seismic capacity is 0.50g~0.60g; and from the perspective of panel safety, the ultimate seismic capacity is likewise 0.50~0.60 g. The research in this paper provides a guide or a reference for the evaluation of the seismic capacity of similar projects.
Modeling and analysis of wave energy generation device using particle swarm optimization algorithm
Authors: Cao Ran 
Published: February 2025

Abstract
This paper studies the maximum power optimization method of swinging buoy wave energy power generation device (PTO system) based on the particle swarm optimization (PSO) algorithm. This device makes the float and the oscillator move relative to each other through the heaving action of the waves, driving the damper to do work and output energy. Based on the wave theory and single-degree-of-freedom damped system model, this paper assumes that seawater is an ideal fluid, establishes a mechanical model of the float and oscillator, and solves the equations of motion through the Runge-Kutta method. The PSO algorithm is then employed, with the damping coefficient serving as the decision variable, to optimize the PTO system’s average output power and determine the maximum power associated with the optimal damping coefficient. The results show that wave height, frequency and floating mass have a significant impact on the system power output, providing a theoretical basis for the optimal design of wave energy power generation devices.
Natural frequencies of axially moving beams with coupled longitudinal–transversal vibrations: Comparison of three methods
Authors: Zhao Jianbo , Tang You-Qi 
Published: February 2025

Abstract
This paper analyzes the coupled vibration problem of viscoelastic beams in axial motion using the Euler-Bernoulli beam theory. A physical model is established that includes parameters such as density, cross-sectional area, elastic modulus, viscoelastic coefficient, support length, and initial axial tension. Based on the generalized Hamiltonian principle, a set of motion equations in coupled transverse and longitudinal forms is derived. The equations are simplified using dimensionless variables and applying simply supported boundary conditions. Numerical simulations are conducted using the Differential Quadrature (DQ) method, the Modified Weight Coefficient method, and the Galerkin truncation method. The first two frequencies are compared for the three methods at transverse and longitudinal truncation orders M=N=8. It is found that the first frequency matches well, while the second frequency shows deviations in the DQ method. Adjusting the order improves the results.
Analysis of algebraic and geometric ideas in infinite series
Authors: Chen Qiao 
Published: February 2025

Abstract
As an important concept in mathematics, the convergence judgment of series has always been one of the research hotspots. As the reference series to judge the convergence and divergence of series, the proof of convergence of P-series and harmonic series has always been a research hotspot. This paper discusses the embodiment of algebra and geometry in the proof of convergence and divergence of P-series and harmonic series. Through the mutual transformation of geometry and algebra, the convergence and divergence of infinite series are analyzed, and the convergence problem of series is transformed into an intuitive geometric image for analysis. By introducing geometric intuition, it can not only simplify the solution process of the problem, but also help students and researchers better understand the essential characteristics of series, so as to provide new perspectives and ideas for the study of series convergence.
