Summary: Healthy food is a major challenge for the development of this century, with plant-parasitic nematodes causing significant damage to global crop yields. The use of chemical nematicides for control is no longer environmentally sustainable, and biocontrol methods, such as biopesticides derived from living organisms, offer a promising alternative. This study focuses on the underexploited ecological niche of lichen microecosystems to develop new plant protection products. The lichen-associated bacterial suspensions from Paenibacillus etheri are investigated for their potential as nematicides against two nematode species, and the effects of volatile organic compounds produced by the bacteria are evaluated.

Summary: This study systematically investigated the hydrogenation of methyl palmitate (MP) to hexadecanol over defect-rich Cu/m-ZrO2 catalysts. It was found that Cu/m-ZrO2-350 catalyst exhibited the best activity for MP hydrogenation due to its highest Cu dispersion, largest number of Cu0 sites, and surface oxygen vacancy concentration. The synergistic effect of Cu species and oxygen vacancies provides insights for the design of efficient catalysts for the conversion of fatty esters to fatty alcohols.

Summary: Soft rot disease in potato is a global problem, with Pectobacterium and Dickeya bacteria being the main culprits. However, this study reveals the involvement of pectinolytic Bacillus and Paenibacillus in soft rot diseases. Isolates collected from potato samples in Tunisia showed pectinolytic activity and the majority belonged to Bacillus pumilus species. This is the first report of soft rot in potato caused by pectinolytic B. pumilus in Tunisia.

Summary: Exploration of novel Paenibacillus species with plant growth-promoting characteristics in low-temperature environments is important for the development of cold-tolerant biofertilizers in forestry and agriculture. Three strains isolated from root endophytes of Larix gmelinii showed plant growth-promoting properties, such as phosphate solubilization, indole-3-acetic acid biosynthesis, and siderophore production at low temperatures. Pairwise sequence analysis of the 16S rRNA genes revealed that the strains represent putatively novel taxa within the genus Paenibacillus. The strains have typical chemotaxonomic characteristics of the genus Paenibacillus and their genomes vary in size and G+C content.

Summary: The study showed that the antibacterial surface of insect wings has bactericidal activity, with surface roughness, nanostructure, and chemical organization playing a key role in preventing bacterial colonization and survival. By examining changes in bacteria morphology under a scanning electron microscope and confirming cell death through staining, the correlation between the nanostructure of the wing surface and bactericidal activity was established.

Summary: There is a growing attention to bio and renewable energies due to the depletion of fossil fuels and global warming. In this study, a modeling and simulation method using artificial intelligence (AI) was developed to predict the production of bioenergy from vegetable bean oil. Various AI methods were applied to predict the yield of Fatty acid methyl esters (FAME) production, and the models were evaluated using different metrics. The results showed high accuracy and the boosted SVR and ANN models demonstrated better prediction efficiency.

Summary: Two Pseudomonas strains, Q1-7 and Q4-3, capable of degrading 3-OH PAME were isolated and identified. They exhibited significant inhibition effects on Ralstonia solanacearum and effectively protected Casuarina equisetifolia, peanut and tomato plants from infection. These findings provide potential resources for the prevention and control of bacterial wilt caused by Ralstonia solanacearum.

Summary: This paper explores the use of natural language processing techniques to predict structured metadata in failure notifications. It highlights the challenges posed by the technical nature of the texts and the use of sentence fragments and abbreviations. The authors demonstrate that considering the dependencies between different components of the metadata and treating the prediction problem as a multidimensional classification problem can improve label prediction reliability.

Summary: In this article, the relationships between the fuzzy betweenness relations and three important mathematical notions, such as fuzzy interval operators, fuzzy partial orders, and fuzzy Peano-Pasch spaces, are explored in the setting of complete residuated lattices. The resulting category of fuzzy betweenness relations with respect to a fuzzy equivalence relation is shown to be isomorphic to that of geometric fuzzy interval spaces. A fuzzy partial order is constructed from a fuzzy betweenness relation, and its relationships are analyzed in depth. Furthermore, the concept of a fuzzy betweenness field is introduced, and it is shown that a vector space over a fuzzy betweenness field can yield a fuzzy Peano-Pasch space in the setting of completely distributive lattices.

Summary: In this paper, the concept of a t-norm on bounded pseudo-ordered sets and bounded trellises is introduced, along with some basic examples. The impact of abandoning transitivity is discussed, highlighting that the meet operation is not a t-norm on a proper bounded trellis, and there may be no or multiple maximal t-norms. A generic construction method is provided to extend a t-norm on an interior range of a given perpendicular to-semi-trellis to the entire trellis, with a specific instantiation based on a finite sub-trellis of right-transitive elements. The focus is also on bounded pseudo-chains and modular trellises. (c) 2023 Elsevier B.V. All rights reserved.

Summary: This paper discusses two-dimensional cellular automata on a triangular grid that maintain the sum of all cell states. To investigate such automata, the split-and-perturb decomposition method is applied to triangular grids, which was originally developed for square grids. This results in a new mathematical tool that can enumerate k-ary number-conserving cellular automata on a triangular grid, regardless of the value of k.

Summary: In order to improve dengue prevention and control efforts, the use of routinely collected data to develop risk maps is recommended. By using data from two municipalities in Cuba, dengue experts identified indicators representative of entomological, epidemiological, and demographic risks to construct risk maps. However, there was low agreement between vulnerability and incidence-based risk maps in areas with a prolonged history of dengue transmission, suggesting that an incidence-based approach may not fully capture the complexity of vulnerability.

Summary: In this paper, non-uniform elementary cellular automata on the infinite grid in the context of number conservation are studied. The study provides a comprehensive description of these automata. Previous research only focused on finite grids and derived hypotheses based on computer experiments. It is found that when considering number conservation for non-uniform cellular automata, the infinite grid cannot be treated as a limiting case of finite grids.

Summary: Individual biology influences population dynamics dependent on the environment through life history. Recent research has integrated metabolic theory with individual-based models to explore the link between individual physiology and demography. However, current population models do not consider individual behaviors, relying instead on imposed population-level relationships. This study proposes extending the model to include individual-scale behaviors and demonstrates its effectiveness in simulating consumer dynamics in a heterogeneous environment.

Summary: This paper discusses two-dimensional cellular automata with rotation symmetry and number conservation. It is shown that if the number of states k is smaller than or equal to six, then each rotation-symmetric number-conserving cellular automaton is isomorphic to some k-ary one. However, an example of a seven-state rotation-symmetric number-conserving cellular automaton is provided in this paper, which demonstrates the importance of not only focusing on cellular automata with {0, 1, ..., k-1} as state sets.
