Published: June 2024

Context Tillering is generally considered counterproductive for grain yield in maize (Zea mays). However, recent research defies that idea and suggests that the effects of tillering on grain yield depend on the yield-environment. Aims To synthesise the impact of tillering on maize grain yield across a wide range of environments. Methods Literature regarding tillering in maize was assessed to create a multi-environment database of grain yield per unit area and per plant of side-by-side comparisons of grain yield of tillered versus de-tillered treatments. Regression analyses and mean comparisons were used to compare the performance of tillered and de-tillered crops. Key results The maximum plant density in the database was 7 plants m−2. Tillered crops out-yielded de-tillered crops irrespective of the de-tillered grain yield (y-intercept = 841 kg ha−1, P < 0.01 and slope = 1, P = 0.91). For the lower tercile of yield-environments (i.e. lower than 5269 kg ha−1), the frequency of lower yields on tillered crops was higher (all database = 0.21, Pampas = 0.5) than in the mid or high terciles (all database < 0.13, Pampas < 0.18). Across environments, individual plant yield was higher for tillered crops (42 g plant−1 or 16% difference), but that difference decreased as the de-tillered individual plant yield decreased turning into zero below 136 g plant−1. Conclusions Within the limitations of the data set, tillering was generally beneficial or indifferent for grain yield, but detrimental effects may be recorded in very low yield-environments. Implications Tillering does not condition maize yield across most environments.

Abstract
Characterizing Venuti’s foreignizing and domesticating strategies as historically dependent, this article
attempts to shed some new light on how such translations – especially the foreignizing ones – emerge in any language. After
discussing the roots of Venuti’s thinking in the American context and redefining foreignization as a strategy that draws on
domestic, yet marginalized, elements, we delve into the theory and practice of two Persian translators, Ahmad Shamlu and Mir
Shamseddin Adib-Soltani. Although their translation practices are ostensibly domesticating, they possess underlying foreignizing
qualities. The implications and intellectual origins of their practices are discussed in the Iranian context, giving rise to a
theoretical perspective that allows for foreignizing in non-Anglophone cultures.
Renormalization of conformal infinity as a stretched horizon
Authors: Riello Aldo , Freidel Laurent 
Published: June 2024

AbstractIn this paper, we provide a comprehensive study of asymptotically flat spacetime in even dimensionsd⩾4. We analyze the most general boundary condition and asymptotic symmetry compatible with Penrose’s definition of asymptotic null infinityIthrough conformal compactification. Following Penrose’s prescription and using a minimal version of the Bondi–Sachs gauge, we show thatIis naturally equipped with a Carrollian stress tensor whose radial derivative defines the asymptotic Weyl tensor. This analysis describes asymptotic infinity as a stretched horizon in the conformally compactified spacetime. We establish that charge aspects conservation can be written as Carrollian Bianchi identities for the asymptotic Weyl tensor. We then provide a covariant renormalization for the asymptotic symplectic potential, which results in a finite symplectic flux and asymptotic charges. The renormalization scheme works even in the presence of logarithmic anomalies.
Electrical transport in nanostructured Ni3Al at low temperatures
Authors: Zhu Dongdong , Dai Fei , Lei Haile 
Published: June 2024

Abstract
The electrical resistivity in nanostructured Ni3Al has been discriminated to be dominated fully by the electron-magnon scattering with spin fluctuations and evolve in the form of T
5/3 and T
3/2 below and above its Curie temperature. In addition to doping into γ′-Ni3Al nanophases, excessive Ni atoms are demonstrated to aggregate at the cores of Ni3Al so that some γ-Ni nanophases are embedded in the γ′-Ni3Al ones for forming the core/shell nanostructure. The itinerant electrons from γ′-Ni3Al nanophases is further suggested to wander around the phonons in both γ-Ni and γ′-Ni3Al nanophases for screening the electron-phonon interactions. Consequently, the conduction electrons are scattered largely by spin fluctuations in γ′-Ni3Al shells to suppress the contribution of phonons to the electron transport in nanostructured Ni3Al.
3D measurement of precise part in complex circumstance using line structured light and improved U-Net
Authors: Zhao Huining , Huang Yongbo , Wan Maosen , Yu Liandong , Liu Fangfang , Xia Haojie 
Published: June 2024

Abstract
Line structured light scanning is extensively utilized for the 3D measurement of precise metal parts, but the curvature surfaces and specific materials of these parts generate specular reflection, making it challenging to accurately extract the center of the laser stripe in complex circumstances. Therefore, the primary challenges are the noise separation in the laser stripe image and the extraction of the laser stripe center under complex circumstances. To solve the above problems, an improved U-Net semantic segmentation algorithm is proposed by adding an attention mechanism and modifying skip connections to the classical U-Net network structure for accurate laser stripe segmentation. Secondly, the dual smoothing method of mean smoothing and Savitzky–Golay smoothing is combined with the Hessian matrix algorithm to complete the subpixel extraction of the center point of the laser stripe. Finally, taking the blade and shaft part as the measurement objects, the experimental results demonstrate that the method can obtain more complete, smoother, and denser results than the traditional method under highly reflective surfaces, vital interference spots, and strong ambient light. The proposed method is used for the 3D measurement of the shaft parts, and the diameter measurement maximum error is 0.029 mm, verifying the feasibility of the proposed method.
Robust pedestrian multi-object tracking in the intelligent bus environment
Authors: Wang Shaohua , Guo Yuhao , Li Yicheng 
Published: June 2024

Abstract
Pedestrian multi-object tracking algorithms aim to maintain identity information of pedestrians by comparing the similarity between trajectories and detections, predicting pedestrian motion trajectories. However, within the context of intelligent bus, challenges arise due to factors such as passenger growth and vehicle vibrations, rendering existing pedestrian multi-object tracking algorithms less accurate. Therefore, this paper proposes an intelligent bus terminal robust pedestrian multi-object tracking algorithm named pure motion (PM), which can consistently and stably track pedestrians. The proposed algorithm employs several key strategies. Firstly, it optimizes trajectory prediction by adapting the aspect ratio of the prediction box based on pedestrian movement, automatically adjusting its shape, and selecting velocity weight coefficients according to different tracking targets. Secondly, it decomposes the homography matrix to acquire motion components and correct predicted results under motion conditions. Subsequently, the algorithm leverages the similarity between detection results and trajectories to retain high-confidence detections, eliminating low-confidence ones associated with background, thereby reducing false negatives and enhancing trajectory coherence. Futhermore, the introduction of detection confidence into trajectory updates to enhances the precision of measurement noise. The proposed algorithm underwent testing in intelligent bus driving scenarios, including turns, waiting for traffic lights, emergency braking, and approaching bus stops. The tracking accuracy on the MOT17-13-val dataset reaches 81.8. The results demonstrate that PM significantly improves the robustness of pedestrian multi-object tracking algorithms in the environment of intelligent bus.

Abstract
At present, the condition monitoring of wind turbine gearbox mostly involves selecting monitoring indicators in advance and establishing normal behavior models based on deep learning. However, single physical monitoring indicator cannot fully characterize the operating status of the wind turbine gearbox. To address the above issues, a wind turbine gearbox condition monitoring method using convolutional neural network (CNN)-long and short term memory network (LSTM)-autoencoder (AE) enabled virtual indicators is proposed in this paper. This method first establishes a cleaning principle to preprocess the data of supervisory control and data acquisition (SCADA) system and screen out effective SCADA data further. A CNN-LSTM-AE monitoring model was trained using SCADA data during normal operating process, various characteristic parameters of the gearbox are integrated to construct the AI-enabled virtual indicators, and meanwhile warning thresholds was determined based on the probability density distribution of virtual indicators to analyze the operating status of the gearbox. Finally, the proposed method was validated using real SCADA data from two wind turbines in a cooperated wind farm with my group. Compared with a single physical indicator, the virtual indicator enables to detect gearbox early faults 5 d in advance, indicating that the proposed method can effectively alert wind turbine gearbox failures.

Published: June 2024

Abstract
Since the middle of the twentieth century, the advent of radio telescopes has brought a whole new way and approach to astronomical observation. For Arecibo-type radio telescopes, the tuning optimization of the active reflecting surface (working paraboloid) is the main factor affecting the reflectance calibration. In this study, leveraging the transformation of spatial coordinates through rotation, we introduce an innovative optimization model specifically for the segmented paraboloid of the Five-hundred-meter Aperture Spherical radio Telescope (Hereinafter referred to as FAST) designed by China astronomer and scientist Nan Rendong. This research constructs the equation for an ideal paraboloid and adjusts the working paraboloid to fit within specified constraints such as the orientation of the target star, the adjustment limit of the actuator, and the spatial coordinates. The study employs a combination of coarse and fine grid searches to identify and record the optimal adjustment scheme of the main cable nodes at different angles and the corresponding 2226 actuator coordinates and telescoping length, based on which we build a back propagation model to continuously modify the adjustment scheme. A combination of geometric simulation and Monte Carlo tests were also used for verification. Furthermore, we delve into the impact of variations between adjacent nodes of the modulating actuators, as well as potential longitudinal and radial changes. Compared to the conventional conditioning model, the segmented solution idealized paraboloid we created increases the original reflection efficiency from 77.92% to 95.56% in the working area of 300 m aperture, it will contributes to enhancing the overall performance of FAST.

Numerical study of cold-formed steel sigma sections under combined bending and web crippling action
Authors: Maria Henna , Sreedevi V M 
Published: June 2024

Abstract
Cold formed steel sigma sections are a part of highly optimized family of steel sections. The presence of folding lines along their webs makes them safe for resisting buckling. However, when the CFS beams are exposed to concentrated transverse loads, it increases their vulnerability to web crippling, resulting in a decrease in their moment capacity. To evaluate the performance of CFS sigma sections in applications involving concentrated loads, a finite element analysis-based investigation has been done to understand their behaviour under combined bending and web crippling loading. Out of the four web crippling load cases specified by the AISI code, only the IOF loading case was considered for the study since the IOF case involves concentrated loading at mid-span. Three sets of FE analyses were done to estimate the capacity of the CFS sigma section under pure bending, pure web crippling and combined bending and web crippling. A comprehensive numerical study has been conducted to select the optimum parameters that affect the combined bending and crippling capacity of the sigma section. The adequacy of interaction rules specified in three major cold-formed steel design standards, North American Specification (AISI S100), Australian/New Zealand Standard (AS/NZS 4600), and Eurocode 3 Part 1.3, which are developed primarily using CFS Z and C sections as a basis, has been evaluated. An empirical relation to predict the combined bending and crippling capacity of the CFS sigma section was proposed using the MARS algorithm, and its appropriateness was checked. The proposed empirical relation can be used as a design tool to predict the combined bending and web crippling capacity of the CFS sigma section for the given set of parameters.

Published: June 2024

Abstract
A novel active control algorithm is proposed in this present study. It is assumed that the shape of the time history of control force is same as that of the shape of time history of ground excitation. Based on the above assumption, control force is determined for a specific target reduction in displacement, velocity and acceleration. Time histories of ground motion compatible to response spectrum are generated for seismic zone three as per Indian seismic conditions. A neural network is trained to generate the desired control force for a specific target reduction. The results of the study show that the reduction provided by the proposed control algorithm matches well with the target reduction.

Published: June 2024

Abstract
This study presents the analysis and design of precast pier as per Indian standard codes. The analysis and design of pier is carried out by considering various loads as per Indian standers and IRC codes. The design of precast pier is carried out using the STAAD. Pro software. To study the effect of water pressure on precast pier various shapes of pier are considered like rectangular, circular, pier with triangular cut, pier with arch. The comparison of dis-placement, stresses, strength, and stiffness of different shapes are analysed to evaluate the behaviour of pier. The design of connection of the precast pier is done using IRC codal provisions. Looking to the results precast pier with circular shape is most suitable shape than other considered shape by having more stiffness in each direction, but to resist stresses the rectangle shaped with arc is good choice. And the displacement of pier having rectangular shape is less compared to circular pier.
A contemporary review on progressive collapse
Authors: Singh Harmanpreet , Mohit Bhandari Dr. 
Published: June 2024

Abstract
This study provides a comprehensive review of the latest analytical and experimental research aim at better understanding the nature of failure propagation and identifying the mechanisms responsible for building collapse. The dynamic collapse of buildings is a serious concern that can be triggered by a range of mishaps, including fires, gas explosions, vehicle collisions, design and construction errors, and natural wear and tear. With the proliferation of complex, multi-functional tall buildings in recent years, safety and stability have often taken a backseat. Additionally, the paper examines various guidelines for preventing collapse, focusing on the role of member action and corresponding material and section sizes in either promoting or hindering the spread of collapse. This study considers several control mechanisms that can be implemented to limit the area of influence following a local failure, thereby reducing the likelihood of a full building collapse. The study concludes that, addressing the risk of progressive collapse requires a multidisciplinary approach that considers structural design, material selection, construction practices, and maintenance procedures.

Published: June 2024

Abstract
This document is the result of multiple investigations carried out by the authors, which have been published or are in the process of being published, where the starting point is a structural system in earthquake resistant steel that is lighter in weight: Special Concentrically Brace Frames SCBF, since in other investigations the authors have compared different steel structural systems and has come to the conclusion that SCBF is the lightest, however it maintains seismic resistant characteristics and is even more rigid than other systems without braces such as Special Moment Frames SMF, additionally it is placed in places where it is not necessary that the frames are braced using ordinary OMF moment frames. Eighteen structural archetypes have been designed, varying the distance between column axes, number of floors, but preserving their geometry and architecture. Of which 9 archetypes are made of SCBF structural steel and 9 of SMF type reinforced concrete. Both materials present acceptable and similar seismic-resistant conditions, so based on these designs, the cost and the amount of CO2 emitted are analyzed, considering the superstructure from level 0+00 and the substructure or foundations. The result is which structure is more environmentally friendly and alternatives of use according to area, number of floors and distances between axes looking for an economic optimization.

Authors: Noatia Bimala , Singh Khwairakpam Lakshman 
Published: June 2024

Abstract
Bulk waste dusts obtained from brick and steel manufactures can be utilized as construction materials in pavement that can save natural resources and reduce environmental pollution. This study aims to explore the potential of waste brick and iron dust as substitutes for stone dust filler in bituminous mixtures. Brick fines was treated with NaOH solutions (2M, 4M, 6M, and 8M) to reduce its high-water absorption, among these 4M NaOH solution was chosen as the most effective one. XRD and SEM tests were used to analyze filler properties. The strength performance of bituminous mixture using stone dust, brick dust, treated brick dust, iron dust were evaluated in terms of Marshall stability, indirect tensile strength, moisture susceptibility, cantabro and creep tests. The performance of the mixture for combination of brick - iron dust (1:1) filler is also determined. It is observed that Marshall stability and flow value of the mixes with untreated brick dust increased by 2.89% and 3.44% respectively as compare to conventional mix but with higher OBC. Marshall stability of the mix with iron dust has increased by 1.57% and but decrease in flow value by 13.21%. The ITS value with treated brick dust is higher than untreated brick dust filler. Whereas the iron dust filler and combined of brick and iron dust (1:1) filler has 6.33% and 4.7% higher ITS value as compared to conventional mix. The cantabro loss & static creep deformation values of mixes using brick and iron dust ranges from 5% to 8% & 1.0 to 1.7mm respectively. As the bituminous mixes with these waste products has shown improvement in strength properties, it can be used as alternative filler in bituminous mixes benefiting the impact of pavement industry in waste management concern.
