In our world today, with rare exceptions, we have become accustomed to a form of leadership in which we promote our leaders into isolated parental positions, relying on them to make decisions for us and clear up the mess when things go wrong. But expecting our leaders to behave as though they are above us will inevitably set up power dynamics which can stifle collaboration and diminish our creativity and independence. In this paper I argue that if our leaders are encouraged to work alongside their teams as nominated and responsible siblings rather than overbearing parents, they will be better equipped to foster cooperative and respectful teamwork and deal more effectively and creatively with rivalry and competition.

Generally, pixel-based classification methods for Land Use Land Cover analysis are likely to produce lower classification accuracy compared to Object Based Image Analysis (OBIA) due to pixel based commissions and omissions. Identification of types of land cover features through satellite image is critical for meeting requirements related to sustainabile management, environmental regulation and policy development for any region. Hence, periodic assessment of spatially distributed cover features through distinct and non-overlapping approaches is the need. In the current study, we aimed to examine the ability of OBIA for optical satellite imagery obtained from LISS IV sensor of the year 2021, with a spatial resolution of 5.8 m during the Rabi season in Pune region, Maharashtra, India. The current study also compare the effectiveness of four different machine learning based classifiers i.e., Perceptron, Sigmoid, MP Neuron and Classification And Regression Tree (CART) integrated with OBIA approach for accurate land use land cover classification. The maximum accuracy was achieved as 75.2% over the iterative process. The agricultural land covered was estimated to be 84.97 km2. The overall classification accuracy of perceptron function was 53.6%, Sigmoid function (73.7%) and CART (75.2%). The study revealed that CART method produced an impressive classification result than the MP neuron considering the time and complexity in developing the algorithm for a smaller area too. By leveraging the spatial context and semantic information captured by image objects, OBIA integrated with Machine Learning approaches offer new opportunities for improved understanding of LULC classification and analysis of remote sensing datasets, contributing to a wide range of applications in environmental monitoring, urban planning, natural resource management, and beyond to achieve United Nation's sustainable development goals.

Quantum information theory has been greatly developed in the past decades, and many theoretical problems are related to matrix theory. We study the equality condition for a matrix inequality, K ⋅rank(∑i=1KR i ⊗ Si) ≥rank(∑i=1KR i ⊗ SiT), where Ri’s are linearly independent matrices of the same size, and Si’s are linearly independent matrices of the same size. The inequality used to be a conjecture since 2013 and has recently been proven in the paper [Z. Song, L. Chen, Y. Sun and M. Hu, IEEE Trans. Inform. Theory 69 (2023) 2385]. We study several cases such as that Ri’s are column vectors and Si’s are of various sizes. It turns out that some cases never satisfy the equality condition. [ABSTRACT FROM AUTHOR]

Bacteria form groups composed of cells and a secreted polymeric matrix that controls their spatial organization. These groups--termed biofilms--can act as refuges from environmental disturbances and from biotic threats, including phages. Despite the ubiquity of temperate phages and bacterial biofilms, live propagation of temperate phages within biofilms has not been characterized on cellular spatial scales. Here, we leverage several approaches to track temperate phages and distinguish between lytic and lysogenic host infections. We determine that lysogeny within Escherichia coli biofilms initially occurs within a predictable region of cell group packing architecture on the biofilm periphery. Because lysogens are generally found on the periphery of large cell groups, where lytic viral infections also reduce local biofilm structural integrity, lysogens are predisposed to disperse into the passing liquid and are overrepresented in downstream biofilms formed from the dispersal pool of the original biofilm-phage system. Comparing our results with those for virulent phages reveals that temperate phages have unique advantages in propagating over long spatial and time scales within and among bacterial biofilms.

Background: Autism spectrum disorder (ASD) is the second-most common neurodevelopmental disorder in childhood. This complex developmental disorder manifests with restricted interests, repetitive behaviors, and difficulties in communication and social awareness. The inherited and acquired causes of ASD impact many and diverse brain regions, challenging efforts to identify a shared neuroanatomical substrate for this range of symptoms. The striatum and its connections are among the most implicated sites of abnormal structure and/or function in ASD. Striatal projection neurons develop in segregated tissue compartments, the matrix and striosome, that are histochemically, pharmacologically, and functionally distinct. Immunohistochemical assessment of ASD and animal models of autism described abnormal matrix:striosome volume ratios, with an possible shift from striosome to matrix volume. Shifting the matrix:striosome ratio could result from expansion in matrix, reduction in striosome, spatial redistribution of the compartments, or a combination of these changes. Each type of ratio-shifting abnormality may predispose to ASD but yield different combinations of ASD features. Methods: We developed a cohort of 426 children and adults (213 matched ASD-control pairs) and performed connectivity-based parcellation (diffusion tractography) of the striatum. This identified voxels with matrix-like and striosome-like patterns of structural connectivity. Results: Matrix-like volume was increased in ASD, with no evident change in the volume or organization of the striosome-like compartment. The inter-compartment volume difference (matrix minus striosome) within each individual was 31% larger in ASD. Matrix-like volume was increased in both caudate and putamen, and in somatotopic zones throughout the rostral-caudal extent of the striatum. Subjects with moderate elevations in ADOS (Autism Diagnostic Observation Schedule) scores had increased matrix-like volume, but those with highly elevated ADOS scores had 3.7-fold larger increases in matrix-like volume. Conclusions: Matrix and striosome are embedded in distinct structural and functional networks, suggesting that compartment-selective injury or maldevelopment may mediate specific and distinct clinical features. Previously, assessing the striatal compartments in humans required post mortem tissue. Striatal parcellation provides a means to assess neuropsychiatric diseases for compartment-specific abnormalities. While this ASD cohort had increased matrix-like volume, other mechanisms that shift the matrix:striosome ratio may also increase the chance of developing the diverse social, sensory, and motor phenotypes of ASD.

In recent years, the interest in the comprehension of the fasciae has significantly grown, together with the necessity of finding a consensus for a terminology of the fasciae in the research and clinical fields. Furthermore, it is becoming necessary to categorize the various types of fascia (superficial, deep, visceral, neural) since they possess different anatomical characteristics, and are implicated in different pathophysiological pathways. While in the past we have described the deep/muscular fascia, the aim of this work is to summarize and catalog the information relating to the human superficial fascia (thickness, cellular end extracellular matrix component, innervation, vascularization).

Developing biodegradable complex fertilizers is crucial for sustainable agriculture to reduce the environmental impact of mineral fertilizers and enhance soil quality. This study evaluated chitosan-based hydrogel coatings for sodium alginate matrices encapsulating amino acid hydrolysates from mealworm larvae, known for their plant growth-promoting properties. The research aims to identify the potential of biopolymer matrices for producing biodegradable slow-release fertilizers and to outline future development pathways necessary for this technology to be usable in the fertilizer industry. Chitosan coatings prepared with citric acid and crosslinked with ascorbic acid optimized plant growth, while those using acetic acid negatively affected it. Water absorption and nutrient release tests showed that chitosan coatings reduced water uptake and slowed initial nutrient release compared to uncoated samples. Leaching assays confirmed controlled-release behavior, with an initial burst followed by stability, driven by alginate–chitosan interactions and ion exchange. The X-ray diffraction (XRD) analysis revealed that adding hydrolysate and chitosan increased amorphousness and reduced porosity, improving structural properties. Thermogravimetric analysis (TGA) and Fourier-transform infrared (FTIR) spectroscopy demonstrated enhanced homogeneity and the presence of chemical interactions, which led to improvements in the material's thermal stability and chemical characteristics. Biodegradation tests indicated greater durability of chitosan-coated composites, although hydrolysate incorporation accelerated decomposition due to its acidic pH. Germination tests confirmed no phytotoxicity and highlighted the potential of biopolymeric matrices for slow nutrient release. These findings indicate the possibilities of chitosan-coated alginate matrices as sustainable fertilizers, emphasizing the importance of adjusting coating composition and hydrolysate pH for enhanced efficacy and environmental benefits. The main recommendation for future research focuses on optimizing the chitosan coating process by exploring whether adding hydrolysate to the chitosan solution can reduce diffusional losses. Additionally, investigating the use of glycerol in the alginate matrix to minimize pore size and subsequent losses during coating is suggested. Future studies should prioritize analyzing percentage losses during the crosslinking of the alginate matrix, chitosan coating, and final shell crosslinking. This pioneering research highlights the potential for encapsulating liquid fertilizers in biopolymer matrices, offering promising applications in modern sustainable agriculture, which has not been studied in other publications.

The choice of efficient methods for the immobilization of high-level waste (HLW) resulting from the reprocessing of spent nuclear fuel (SNF) is an important scientific and practical task. The current policy of managing HLW within a closed nuclear fuel cycle envisages its vitrification into borosilicate (B-Si) or alumina–phosphate (Al-P) glasses. These wasteforms have rather limited waste loading and can potentially impair their retaining properties on devitrification. The optimal solution for HLW immobilization could be separating radionuclides into groups using dedicated capacious durable matrices. The phases of the Nd2O3–ZrO2–TiO2 system in this respect are promising hosts for the REE (rare earth elements: Nd, Ce, La, Pr, Sm, Gd, Y) –MA (MA: Am, Cm) fraction of HLW. In this manuscript, we present data on the composition of the samples analyzed, their durability in hot water, their behavior under irradiation, and their industrial manufacturing methods.

Purpose: This paper aims to develop a conceptual framework that jointly considers Environmental, Social and Governance (ESG) factors and organisational resilience (OR) components to ameliorate organisations' understanding of sustainability's overall requirements and related decision-making processes. Design/methodology/approach: This paper combines ESG and OR through a 3x3 conceptual matrix, where ESG factors are listed along the vertical axis and OR components along the horizontal axis. This results in nine quadrants, which have been read according to two arrangements: (1) static, looking at the specific characteristics of each single quadrant, and (2) dynamic, investigating the relationships between the different quadrants according to the system theory (ST) lens. Findings: The integration between ESG and OR results in nine organisational typologies, each characterised by a specific focus: (1) green visioning, (2) eco ethos, (3) climate guard, (4) inclusive strategy, (5) empathy ethos, (6) community shield, (7) ethical blueprint, (8) integrity ethos and (9) compliance guard. These typologies and related focuses determine the different strategic options of organisations, the decision-making emphasis concerning ESG factors and OR components and the organisation's behaviour concerning its internal and external environment. According to ST, the nine typologies interact with each other, emphasising the existence of interconnectedness, interdependence and cascading effects between ESG and OR. Originality/value: The paper represents a unique attempt to interrelate ESG factors and OR components according to a ST lens, emphasising the dynamic nature of their interactions and organisations' need for continuous adaptation and learning to make decisions that create sustainable long-term value.

This paper presents analytical formulations for systematically deriving the solutions of Biot’s poroelasticity in saturated multilayered media of either full-space or halfspace extents. The number of the saturated multilayer media is either n + 2 for full-space extent or n + 1 for halfspace extent, where n is a positive or zero integer. The applied loadings include the internal forces and liquid source for full-space and both internal and external loadings for halfspace region with eight cases of four boundary conditions. The mathematical tools for the formulations are classical and include the two-dimensional Fourier transform, the Hankel transform, Laplace transform as well as linear algebra. The solutions are expressed in matrix forms and each matrix is explicitly expressed with clear physical meaning and well-defined elements. The matrix solutions in the Fourier and Laplace transform domains are axially symmetric about the vertical axis. The internal and boundary conditions can be four-dimensional and the matrix solutions in the physical domain are also four-dimensional. [ABSTRACT FROM AUTHOR]

Recently, the analog matrix computing (AMC) concept has been proposed for fast, efficient matrix operations, by configuring global feedback loops with crosspoint resistive memory arrays and operational amplifiers (OAs). The implementation of a general real-valued matrix (containing both positive and negative elements) is enabled by using a set of analog inverters, which, however, is considered inefficient regarding circuit compactness, power consumption, and temporal response. Here, with the assistance of the conductance compensation (CC) strategy to take full advantage of the inherent differential inputs of OAs, new AMC circuits without analog inverters are designed. Such a design saves the area occupation and power dissipation of analog inverters, and thus turns to be smaller and lower-power. Simulation results reveal that the new circuit also shows a faster response towards the steady state, thanks to the reduction of poles in the circuit, which, again, is contributed by the elimination of analog inverters. Along with all of these benefits, extensive simulations demonstrate that the CC-AMC circuits do not compromise the computing performance in terms of relative error caused by various non-ideal factors in the circuit.

The primary node molecules in the cell signaling network in cancer tissues are maladjusted and mutated in comparison to normal tissues, which promotes the occurrence and progression of cancer. Pancreatic cancer (PC) is a highly fatal cancer with increasing incidence and low five-year survival rates. Currently, there are several therapies that target cell signaling networks in PC. However, PC is a "cold tumor" with a unique immunosuppressive tumor microenvironment (poor effector T cell infiltration, low antigen specificity), and targeting a single gene or pathway is basically ineffective in clinical practice. Targeted matrix therapy, targeted metabolic therapy, targeted mutant gene therapy, immunosuppressive therapy, cancer vaccines, and other emerging therapies have shown great therapeutic potential, but results have been disappointing. Therefore, we summarize the identified and potential drug-resistant cell signaling networks aimed at overcoming barriers to existing PC therapies. [ABSTRACT FROM AUTHOR]

Saponins are natural glycosides found in many plant species; they have a hydrophobic region, consisting of a steroid or triterpenoid skeleton called an aglycone, and a hydrophilic region, consisting of sugar chains attached to the aglycone through ether or ester linkages. This combination of polar and nonpolar elements endows saponins with soap-like behaviour in aqueous solutions. Owing to their structural characteristics, the amphiphilic nature of saponins is responsible for their foaming properties, as well as other biological functions, including their haemolytic activity. The adjuvant properties of saponins were known many years ago, but only in recent years have saponins been approved for human vaccine use in this manner. Saponins from Quillaja saponaria bark are the only source of approved preparations for human use, but a related species, Quillaja brasiliensis, also contains similar saponin compositions that can be obtained from leaves. In this work, we describe the different preparations of saponins used for adjuvants and the purification methods used to obtain each saponin. [ABSTRACT FROM AUTHOR]

AbstractThe food matrix which includes the physiochemical structure and interaction with chemical constituents is a focus of investigation that is revealing potentially important influences on diet and health. This paper, the first in an article collection titled, The Important Role of the Dairy Matrix in Diet and Health, serves as an introduction to the food matrix to put into context the subsequent articles specific to the matrix effects of dairy milk, cheese and yogurt on human health. This introductory article describes the effects of processing on the food matrix and implications for diet and health, examines the contribution of nutrients compared to whole foods and food patterns, and characterizes examples of the complexity of the food matrix including current controversies of dairy fat and ultra-processed foods. The gaps in knowledge and research identified in this overview may help guide researchers and funding entities moving forward. Current knowledge indicates that translating research on the food matrix to the consumer through recommendations for the intake of whole foods and food patterns is prudent at this time.

SiCf/SiC composites have emerged as one of the most promising materials for aero‐engine hot‐end structures. However, their performance is limited by their susceptibility to oxidation and corrosion reactions with oxygen and water vapor. To overcome this challenge, antioxidant‐modified phases are introduced into matrices of SiCf/SiC composites which improve their water and oxygen resistance. In this study, the resistance of SiCf/SiC composites modified by yttrium silicate matrix (SiCf/SiC‐YS composites) to air at 1000–1400°C and water‐oxygen environments at 1200°C was investigated. The diffusion paths of oxygen in SiCf/SiC‐YS composites and the antioxidant behavior of the yttrium silicate matrix were discussed. Additionally, the differences in oxygen and water‐oxygen corrosion resistance of SiCf/SiC‐YS composites at the same temperature were compared. The strength retention of SiCf/SiC‐YS composites after oxidation and water‐oxygen corrosion at 1200°C were 138.6% and 108.8%, respectively. This indicates that the addition of water vapor accelerated the degradation of SiCf/SiC‐YS composites. By comparing with SiCf/SiC composites, it can be concluded that the modification of the yttrium silicate matrix considerably improved the oxidation resistance of SiCf/SiC composites.

ABSTRACT A primary question for researchers in the field of conservation science concerns the fragmentation of biodiversity‐supporting habitat. Key debates revolve around the relevance of habitat composition and configuration for conservation outcomes. Central to this debate is the measurement and delineation of the habitat patch, which informs fragmentation‐related metrics and their evaluation. Despite the need to quantify and model habitat fragmentation, the habitat patch concept itself has been subject to criticism concerning its ability to adequately reflect the heterogeneity of resource distributions in complex landscapes. In this paper, we present the continuity‐contiguity problem, which is one of the fundamental challenges related to the delineation of habitat in space, and discuss its implications for fragmentation‐biodiversity research. We outline the potential contribution of recent developments in spatial‐ecological methods and the leveraging of uncertainty in the modelling process to address four common issues related to the habitat patch concept: the gap‐crossing problem, the need for multi‐variate habitat delineation, the delineation of interior‐edge transitions and the need to parameterise habitat as both a discrete and continuous spatial entity. We conclude with several recommendations for studies on fragmentation‐biodiversity outcomes where the continuity‐contiguity problem may influence the research process. [ABSTRACT FROM AUTHOR]

Let S be an additively idempotent semiring and M n (S) be the semiring of all n × n matrices over S. We characterize the conditions of when the semiring M n (S) is congruence-simple provided that the semiring S is either commutative or finite. We also give a characterization of when the semiring M n (S) is subdirectly irreducible for S being almost integral (i.e. x y + y x + x = x for all x , y ∈ S). In particular, we provide this characterization for the semirings S derived from the pseudo MV-algebras. [ABSTRACT FROM AUTHOR]

In this paper, a study of carbon fiber reinforced plastic tubes, which are widely used in overwhelming of technical industries, including aerospace industry, with single and combined winding angles (30°, 45°, 60° and 80°) fabricated by wet winding method on X-Winder machine has been carried out. The core problem addressed in this research is identifying optimal winding angles of carbon fiber reinforced plastic tubes at which the strength parameters remain in a relative equilibrium. Compressive strength, tensile strength and impact strength tests were carried out. The results of specimens with single winding angle showed that a maximum tensile strength of 630 MPa was achieved at a winding angle of ±30° and a maximum compressive strength of 380 MPa was achieved at an angle of ±80°. The maximum value of impact strength was achieved at a winding angle of ±60°. In order to obtain a balance in the strength characteristics of the tubular rods, combined reinforced winding with ±30°/45°, ±30°/60°, ±30°/80°, ±80°/45° and ±80°/60° angles were investigated. High values of compressive strength of 434 MPa, tensile strength of 675 MPa and impact strength of 165 kJ/m² were achieved with ±30°/80° combined winding angle. The fibers of the material, which were oriented closer to the compression direction, resulted in reduced efficiency of transferring compressive forces between the fibers and decreased compressive strength. This uniform stress distribution permitted the load to be equally divided between the fibers, which effectively utilized their strength properties. Thus, results confirmed the importance of selecting the optimal winding angles to create carbon fiber reinforced plastic tubes with the required strength properties. [ABSTRACT FROM AUTHOR]

Introduction. Mathematical modeling in food technology plays a key role in solving many theoretical and practical problems. At the stage of creating new recipes, it becomes one of the effective methods that allows reducing the time and costs of development, reducing the scope of testing, guaranteeing the required quality of the finished product and increasing the competitiveness of products. The research focuses on the bakery product recipe with the addition of whole grain sorghum flour. Grain sorghum of the Bachelor variety is zoned in the Saratov region. It has a high yield of 2.5-3.5 t / ha. It tolerates high temperatures and moisture deficiencies well, and it is resistant to diseases and pests. The nutritional value is due to the high content of protein and starch. The goal of the research was to develop the ratio of recipe components in a bakery product with the addition of whole-grain flour from grain sorghum. The studies were conducted sequentially. 1.The demand for fortified bakery products of consumers in the Saratov region using a questionnaire was studied. 2. The recipe for bakery products with whole-grain flour from grain sorghum using regression analysis was developed. This method made it possible to determine the regression dependence, study the properties of parameter estimates when proposing probable characteristics of facts and random errors of the model. Using linear regression, a linear function of porosity, specific volume, mass fraction of moisture, and vitamin P content was found. The result of the research was the solution to the problem of modeling the relationships between the selected variables and predicting the values of the dependent variable based on the model, which made it possible to compile a matrix of studies of fortified bakery products with whole grain flour from grain sorghum.

Video mosaicing is a computer vision and image processing technique used to create a panoramic or wide-angle view from a sequence of video frames. The goal is to seamlessly combine multiple video frames to form a larger and more comprehensive view of a scene. In recent years, the field of image processing has witnessed a growing interest in video mosaic research owing to its application in surveillance and defense applications. This paper introduces an automatic algorithm for video mosaic creation, addressing the alignment and blending of non-overlapping frames within each input video. The proposed algorithm navigates through several key steps to achieve a seamless and continuous mosaic, particularly tackling issues related to camera motion and content variations across frames. The effect of the good number of matches to be chosen while performing frame stitching is evaluated. The proposed algorithm effectively produces a video mosaic with aligned and blended non-overlapping frames, resulting in a visually continuous mosaic. The output video serves as a testament to the algorithm's prowess in addressing challenges related to video frame alignment and blending. [ABSTRACT FROM AUTHOR]

Multigranulation rough set is composed of a set of granularities, providing a theoretical framework for solving problems from a multigranulation perspective. Feature selection aims to find the minimal set of attributes that does not compromise the overall classification capability. It has significant applications in the field of information processing. However, in practical application environments, the granularities in information systems often evolve dynamically over time. To address this scenario, an incremental feature selection algorithm for data with changing granularities in local multigranulation neighborhood covering rough sets is proposed. Firstly, the method of local related family is introduced, relationships between matrix operations of local related sets and those of approximate sets are discussed, and feature selection is studied using matrix methods. Subsequently, two matrix-based incremental feature selection algorithms are proposed for the cases where granularity structures in the data are added or deleted due to feature changes. Experiments on six datasets from UCI are then conducted to evaluate the performance of the proposed algorithms. The experimental results demonstrate that the two proposed incremental feature selection algorithms are highly effective. [ABSTRACT FROM AUTHOR]
