Micron scale binary periodic phase plate for increased depth of focusing based on a non local analysis and design In order to focus light at a desired depth, wavefront shaping of the incident light is required. Light focusing is used in applications such as medical imaging, sensing, power dividers, etc. For this purpose, various phase plates can be exploited, but we propose a periodic phase plate. The reason for considering periodic structures is to profit from wavefront shaping of several periods to focus light at larger depths, which can be a challenging task without a periodic phase plate. Using this method, the focus quality is such that its Full Width at Half Maximum (FWHM) reaches in the order of the diffraction limit, while maximizing power concentration. We also assume that the phase plate elements are of micron-scale, so that it does not require nanofabrication. The modelling and analysis method used in this paper accurately takes the coupling among adjacent phase plate elements into account, i.e., it does not rely on local phase approximation. Since the introduced phase plate has a periodic structure, the focusing is repeated periodically, which finds several applications. Using our computational technique, one is able to rigorously analyze and design phase plates as wide as [Formula: see text]. In a sample design, we show that [Formula: see text] of the illuminated power reaches a depth of [Formula: see text] or 1m at a wavelength of [Formula: see text]. Approximately [Formula: see text] of the incident power is focused within only [Formula: see text] of the unit cell width. Moreover, despite large depth of focusing, its FWHM is in the order of the diffraction limit. In this paper, in addition to achieving light focusing at larger depths, we also demonstrate that the proposed methodology can be utilized for focusing with a FWHM close to the diffraction limit down to [Formula: see text], double focusing, and focusing with a high Numerical Aperture (NA) of 0.97.

Mini-Jacquard Weft-Knit in Peruvian Pima Cotton as a Print-Free Alternative: CAD Simulation, Prototyping, and Fabric Pattern Characterization This study develops and validates a weft knitted Mini-Jacquard in Peruvian Pima cotton as a print-free coloration strategy by integrating CAD-based pattern simulation with prototype manufacturing. A three-color design (red, blue, white) was programmed on a flat knitting machine using a 10 × 14 rapport. Color-wise yarn consumption was computed directly from the digital pattern, and the physical sample was characterized through combustion testing and optical micrographs. The prototype exhibited a yarn count of ~20/1 Ne, S-twist (~11.18 TPI), and 100% cellulosic composition. The blue yarn showed the highest consumption (≈73.81%), followed by white (≈19.65%) and red (≈6.55%), consistent with the digital rapport’s color distribution. The CAD stage ensured pattern fidelity and supported raw-material planning; the knitted sample showed a soft hand, dimensional stability, and sharp motif definition upon visual assessment. A sustainability and comparative analysis with chemical printing was conducted, revealing that the Mini-Jacquard achieved the highest design accuracy and tactile comfort, outperforming screen printing and heat transfer in geometric fidelity, chromatic homogeneity, and texture. The Mini-Jacquard optimized operational times (320 min/m2) compared to transfer printing (332 min/m2) and screen printing (740 min/m2), reducing process stages and complexity. Although Jacquard production involves higher energy costs ($34.8) and material expenses ($11.6), it provides greater structural value and durability, positioning it for high-end applications. Moreover, the Mini-Jacquard could reduce water consumption by approximately 90% and thermal energy use by 70%, eliminating chemical residues and extending fabric lifespan, thus offering high sustainability and circular potential. A transparent scenario-based analysis indicates substantial reductions in water and thermal-energy use when omitting printing/fixation/washing stages, along with the elimination of printing-stage effluents. Overall, design-integrated coloration via Mini-Jacquard is technically feasible and potentially eco-efficient for Pima-cotton value chains, with applications in apparel, accessories, and functional textiles.

The Effect of Different Sizes and Widths of Markers on the Nesting Efficiency when using Some Software "Case study of a Model of Children's Clothing" Efficient fabric use or reduction in fabric consumption has a direct impact on the economy and the environment. Efficient material use can lower the production cost per garment and reduce the need for fabric consumption, thus easing pressure on natural resources. Marker production is a critical process in garment manufacturing before fabrics are cut for production, ensuring maximum utilization of the fabrics used. Any reduction in the amount of fabric used per garment results in greater savings and increased profit margins. With technological advancements, marker efficiency can now be automatically calculated using specialized marker planning software, increasing the accuracy and speed of the process. The aim of this research is to study how to achieve the best nesting efficiency in ready-made garment factories through the effect of different sizes and widths of the marker when using more than one ready-made pattern program and the effect of different sizes and widths of the marker using different programs on the nesting efficiency of each of them. A model of a children's overalls was designed and prepared from single jersey material, then grading and nesting were done for 6 consecutive sizes (0-3 months, 3-6 months, 6-9 months, 9-12 months, 12-18 months, 18-24 months) to make the marker for each program using three different widths of the marker (85-150-170) cm. The application was carried out on three ready-made programs, which are: (Gemini X8) program, (10 Gerber) program, and (7.3 CLO-3D) program.

Exploring YOLO Algorithm application in Smart Traps for Fruit Pest Detection Agricultural practices are essential for modern civilization and have significantly contributed to population growth in recent years. Food production depends heavily on the natural environment; however, pests can severely damage crops and are often difficult to control. This emphasizes the urgent need for effective pest control measures to protect agriculture. One common way to manage insect pests is by using traps. These traps typically employ bait to attract insects, often consisting of sexual pheromones or food, and they have a mechanism that captures the insect when it attempts to enter. This work explores the training and application of various size variants and versions of the modern object classification algorithm, You Only Look Once (YOLO), during the classification phase of real-time object detection. The focus is on two predominant pests associated with fruit cultivation: Ceratitis capitata and Grapholita molesta. The study utilizes a limited dataset to maximize performance and computational metrics in an intelligent trap-controlled environment.

Multi-Scale Feature Analysis Method for Soil Heavy Metal Based on Two-Dimensional Empirical Mode Decomposition: An Example of Arsenic The spatial distribution of soil heavy metals was influenced by both natural and anthropogenic factors, and the multi-scale characteristics of heavy metals played a key role in analyzing their influencing factors. Taking arsenic (As) of an oil refining site in Shandong as an example, the As was firstly decomposed into intrinsic mode functions (IMFs) at different scales and a residual using two-dimensional empirical mode decomposition (EMD). Secondly, the spatial variation scales of As, the IMFs, and the residual were quantified by their semi-variograms, respectively. Finally, local spatial correlation analysis and random forest model were employed to analyze the multi-scale features of As, the IMFs, the residual, and environmental variables. The results indicated that the As was decomposed into IMF1, IMF2, IMF3, and a residual using the two-dimensional EMD method, and the corresponding spatial ranges were 72.60 m, 159.30 m, 448.00 m, and 592.36 m, respectively. IMF3 had the highest percentage of variance with a value of 57.56%, indicating that the spatial variation of As was mainly concentrated on a large scale. There were correlations between As and aspect and land use type. However, after the scale decomposition of two-dimensional EMD, there were significant correlations between oil residue thickness and IMF1, land use type and IMF3, land use type, and aspect and residual, respectively. The IMFs and residual had a significant scale–location dependence on environment variables, and the impact of anthropogenic factors on As was mainly reflected at the small and medium scales, while the influence of natural factors was mainly reflected at the large scale. The developed method can provide a methodological framework for the spatial analysis and pollution control of soil heavy metals.

Mode Integration Disorder Metamaterials: Electromagnetic Wave Manipulation From Arbitrary Coupled Modes to Single Mode ABSTRACT Disordered metamaterials, characterized by both the disordered configurations of individual meta‐cells and their irregular spatial arrangements, represent a novel class of metamaterials. Such structural disorder endows them with distinctive electromagnetic properties, enabling the manipulation of nonuniform electromagnetic waves composed of multiple coupled modes. In this study, we investigate the capability of disordered metamaterials to convert arbitrary multimode inputs into a single‐mode output, termed mode integration. By analyzing the scattering behavior of these metamaterials, we formulate matrix‐based scattering parameters that describe their electromagnetic responses under coupled‐mode excitation, and identify specific features of these parameters that signify mode‐integration capability. To design disordered metamaterial structures that satisfy the desired scattering characteristics, we first induce output fields containing the target mode using randomly generated disordered structures. Then, by concatenating multiple disordered structures, the unwanted modal components are progressively suppressed, yielding a single‐mode output. Using a genetic algorithm, scattering matrices meeting the target criteria can be efficiently assembled from a predefined database of random disordered structures. Finally, full‐wave simulations of the designed structure under different excitation modes provide detailed insight into the modal evolution along the propagation direction, clearly demonstrating the successful integration of arbitrary coupled modes into a single target mode.
