Leveraging the Synergy of Digital Twins and Artificial Intelligence for Sustainable Power Grids: A Scoping Review

As outlined by the International Energy Agency, 44% of carbon emissions in 2021 were attributed to electricity and heat generation. Under this critical scenario, the power industry has adopted technologies promoting sustainability in the form of smart grids, microgrids, and renewable energy. To overcome the technical challenges associated with these emerging approaches and to preserve the stability and reliability of the power system, integrating advanced digital technologies such as Digital Twins (DTs) and Artificial Intelligence (AI) is crucial. While existing research has explored DTs and AI in power systems separately, an overarching review of their combined, synergetic application in sustainable power systems is lacking. Hence, in this work, a comprehensive scoping review is conducted under the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews (PRISMA-ScR). The main results of this review analysed the breadth and relationships among power systems, DTs, and AI dynamics and presented an evolutionary timeline with three distinct periods of maturity. The prominent utilisation of deep learning, supervised learning, reinforcement learning, and swarm intelligence techniques was identified as mainly constrained to power system operations and maintenance functions, along with the potential for more sophisticated AI techniques in computer vision, natural language processing, and smart robotics. This review also discovered sustainability-related objectives addressed by AI-powered DTs in power systems, encompassing renewable energy integration and energy efficiency, while encouraging the investigation of more direct efforts on sustainable power systems.

Reproductive biology of the rock oyster Striostrea prismatica in two populations of the Mexican Central Pacific

ABSTRACT The oyster Striostrea prismatica is a fishery-relevant species in the eastern tropical Pacific, particularly in the Mexican Central Pacific (MCP), and little is known about its reproductive cycle. Therefore, our study analysed gametogenesis, sex ratio, sexual maturity stages, shell height at first maturity, and condition index during 2014 and 2015 in El Tizate and La Victoria in the MCP. The sex ratio was significantly biased towards males at both sites, presumably due to ontogeny or fishing pressure. The highest condition index was observed between April and May in both years, while lower values were observed from September to December. The reproductive cycle in both sites was annual, with maturity and spawning from June to August and the degradation phase in August. The condition index showed a negative correlation with temperature and chlorophyll a in both sites: as a result, the period of maximum maturity and spawning coincided with the closure of the fishery in Mexico (June-August). Females had more significant shell height at first maturity than males at both sites, possibly associated with fishing pressure. The information from this study is a significant contribution, but it is necessary to extend the studies to populations further south and further north.

Managing earliness and yield of cotton by modulating plant population, foliar boron feeding and mepiquat chloride application

ABSTRACT Early maturity and simultaneous increase in yield of cotton are pivotal for increasing the productivity of cropping systems involving cotton. Current two-year study was performed to simultaneously enhance the earliness and yield of cotton by modulating plant population (PP) (5.3 and 8.8 plants m−2), foliar boron (B) (0, 0.6 and 1.2 g/L B) and 0.07 g/L mepiquat chloride (MC) solution (at squaring and flowering stages) application. Internodes length was exalted at high PP (8.8 plants m-2) and B (1.2 g/L B), while declined by MC. Nevertheless, nodes above the white flower and cracked boll were decreased at high PP, and the application of B and MC indicated earlier cutout. Similarly, high PP, and application of 1.2 g/L B and MC at squaring reduced calendar and thermal time needed for flowering and boll opening. The boll maturation period was not affected by the application of B and MC but declined at high PP. Earliness index, production rate index (PRI) and seed cotton yield were increased at high PP, application of 1.2 g/L B and MC at squaring. In crux, increasing PP and B concentration, and MC application at squaring resulted in early maturity and enhanced seed cotton yield by modulating plant structure and time required for various phenophases.

Underplating-induced trans-crustal melting and maturation of Neoarchean continental crust in the North China Craton

A global change in granitoid compositions from early predominantly sodic tonalite-trondhjemite-granodiorites (TTGs) to later TTGs and more potassic granites occurred during the late Archean, coupled with a major period of crustal maturation. However, the detailed relationship between granitoid chemical evolution and the maturing crustal process remains enigmatic. Successive granitoid magmatism including late Neoarchean TTGs and high-K granites occurred in the Western Shandong Province granite-greenstone belt (WSP) of the North China Craton and thus preserves crucial clues of the crustal maturation process. In this study, petrology, whole-rock geochemistry, and zircon U-Pb and Lu-Hf isotopes are reported for the late Neoarchean TTG gneisses, monzogranites, and minor metabasaltic to andesitic rocks from the WSP. The ca. 2560−2540 Ma TTG gneisses show low MgO, K2O/Na2O, but high (La/Yb)N, Sr/Y, and absence of Eu anomalies, indicating their derivation from partial melting of the thickened lower mafic crust. The ca. 2530−2500 Ma monzogranites are characterized by systematically high SiO2 and K2O/Na2O, but low MgO and Sr/Y, and moderately negative Eu anomalies, revealing they were formed by intracrustal reworking of local TTGs and sedimentary rocks in the middle to upper crust. Geochemical variations of these crustal-derived granitoids suggest that they were formed by melting at gradually higher crustal levels with the melt zone moved gradationally from the eclogite stability field into the plagioclase stability field. The ca. 2530−2500 Ma calc-alkaline metabasaltic to andesitic rocks sourced from metasomatized mantle outline roles of mantle-derived magma underplating in contributions of heating and trans-crustal melting magmatism. The long-term melting processes facilitated the upward movement of volatiles and heat-producing elements from deep to shallow crustal levels, and introduced K-enriched monzogranites into the upper crust, leaving a refractory, strengthening, and tectonically stable lower crust. Secular compositional evolution of crustal-derived granitoids reveals that continuous crustal reworking drove lithosphere differentiation and paved the way for the maturation of the Archean continental crust.

Interferon-β-Induced Injury During Pediatric Muscle Differentiation: Insight Into Juvenile Dermatomyositis Pathogenesis.

Juvenile dermatomyositis (JDM) involves up-regulated type I interferons (IFNs), including IFNβ, yet pathologic mechanisms remain poorly understood. We aimed to characterize the functional and structural effects of IFNβ on in vitro human pediatric myoblast growth and differentiation in a three-dimensional skeletal muscle model (myobundles). Myobundles fabricated from myoblasts of a healthy pediatric donor were exposed to IFNβ at 0 to 5,600 IU/mL during growth (days 1-4), differentiation (days 4-11), and/or mature (days 11-18) periods. To assess myobundle structure and function, contractile force, kinetics, and fatigue were measured at day 18 with subsequent immunohistochemistry. Myobundles were not functionally affected by IFNβ exposure during growth period alone. However, when IFNβ exposure continued through differentiation, myobundles became dysfunctional (P < 0.0001). IFNβ during differentiation or mature periods alone resulted in dose-dependent decreases in contractility, with greater decrease in the differentiation alone group (P < 0.0001). Twitch kinetics and fatigue remained largely unchanged when myobundles were exposed to IFNβ only during growth, yet twitch time slowed (P < 0.005) and fatigue decreased (P < 0.002) when myobundles were exposed during differentiation or mature stages alone. Nuclei density and myofiber size and organization also decreased when IFNβ was added during differentiation period alone. IFNβ decreases pediatric myobundle contractile function most significantly during differentiation of myoblasts to myotubes. Function is not affected when IFNβ exposure is limited to myoblast proliferation alone. These findings implicate a pathologic role for IFNβ in JDM by impairing myoblast differentiation, leading to subsequent loss of function and ongoing need for muscle regeneration and repair.

Comparative analysis of the parameters of the external diameter of the isthmus, ampulla and funnel of the fallopian tubes in women giving birth in the first and second periods of adulthood

During an in-depth analysis of the management of patients of older age groups, another equally important category of the population is overlooked - patients of the second period of adulthood. In no case should this period of life be missed, especially in relation to women. It is in this age period that the menopause process occurs, which determines the further involutive restructuring of the reproductive system in particular and the entire body as a whole. It is advisable to study the morphological dynamics of the fallopian tubes, which are a key link in the female reproductive system. Objective: in a comparative aspect, to analyze the parameters of the outer diameter of the isthmus, ampoule and funnel of the fallopian tubes in women who gave birth in the first and second periods of adulthood according to the sectional study and calculate the correlation relationship. The study was performed on autopsy material in the period 2018-2022, the analysis of the results of morphometry of both fallopian tubes of 49 deceased women who gave birth at the age of 22-56 years was carried out. Group I included 26 women of the first period of adulthood (22-35 years old), group II included 23 women of the second period of adulthood (36-56 years old). The outer diameter of the fallopian tube funnel was determined using a micrometer after their isolation from the pelvic cavity. Having determined the size of the semicircle of the pipe, their diameter was calculated. The tendency to the predominance of the parameters of the outer diameter of the fallopian tubes in the second period of adulthood in comparison with the representatives of the first period of adulthood (p &gt; 0.05) has been established. Thus, the outer diameter from the first period of adulthood to the second period at the isthmus site increases by 4.5 % in the right fallopian tube and by 6.25 % in the left fallopian tube, at the ampoule site - by 1 and 0.7 %, respectively, and at the funnel site - by 3.1 and 4.2 %, respectively. The tendency to the prevalence of parameters in each studied section of the right fallopian tube over similar ones in the left (p &gt; 0.05) is determined. The results obtained during the sectional examination of the autopsy material can form the basis for studying the age-related anatomy of the fallopian tubes. The data form the basis for further clinical and morphological studies, as well as provide an understanding of the age characteristics of various sections of the fallopian tubes for the application of this information in practical medicine, for example, in the differential diagnosis of pathological conditions.

External nutrients fattening promotes hepatopancreases development, metabolism, nutrient deposition and flavor yield during the maturation stage in female Chinese mitten crab (Eriocheir sinensis)

The nutritive value and maturity status of hepatopancreases dominates the quality of Chinese mitten crab, Eriocheir sinensis. However, the underlying function and regulatory mechanism, as well as the external nutrient factors on the development of hepatopancreases in different growth stages of E. sinensis remains unclear. In this study, we first revealed the function of hepatopancreases feeding with iced trash fish (ITF) during the whole culture period; and further investigated the underlying mechanism on nutrient deposition and flavor yield feeding with formulated feed (FEED) in replacement of ITF in female E. sinensis. From the results, growth performance and metabolism indicate E. sinensis was robustly developed, and ITF promotes growth and hepatopancreases development during the maturation period. Meanwhile, activation of fatty acid and amino acid metabolism in hepatopancreases resulted in depletion of monounsaturated fatty acids (MUFAs) but promoted protein deposition during the maturation stage. Integrated analysis of transcriptome and metabolome reveal metabolism, biosynthesis, and flavor presentation were intensively active during maturation, evidenced by the expression of key genes of ALDH, TBXAs, HADHA, UPB1, CYP2, GST, and γ-GT-X1; as well as the key metabolites of GMP and IMP. Additionally, substitution of ITF with FEED further confirm full price artificial feed could meet the nutrient requirements during the maturation period, evidenced by the growth performance, fatty acid and amino acid derived nutrient and flavor yield in hepatopancreases. In conclusion, nutrient and flavor deposition was associated with the fast development of hepatopancreases, and fatten with full price compound feed contributes to the nutrient requirement and flavor yield during the maturation stage.

Self-creation of Older People in the Perspective of Developing Wisdom and Adaptation to Changing Roles in the Family and Society

Old age is a stage of life during which a person must confront the changes that occur both in the reality around them and in themself. Those are changes at the biological, psychological and social levels. Adapting to old age and the roles it brings becomes a difficult and demanding task. One of the most important developmental tasks of an elderly person is developing wisdom that can support and facilitate the process of adaptation to old age. Entering the period of late adulthood is therefore a special opportunity for further development and self-creative action of the individual leading to the creation of a mature identity of an old person. The aim of this text is to provide insight into the meaning and manifestations of this self-creative involvement, with particular emphasis on its importance in the process of adaptation to changing roles in old age and building wisdom.

How does data factor utilization stimulate corporate total factor productivity: A discussion of the productivity paradox

Stimulating total factor productivity through the utilization of data factors is a crucial concern for companies operating in the digital era. This study employs data from A-share listed firms from 2011 to 2022 to examine the impact and mechanisms of data utilization on corporate total factor productivity. The findings reveal that effective data utilization can significantly improve corporate total factor productivity, but no evidence supports the productivity dilemma. The stimulating effects are achieved by alleviating investment inefficiency and resource redundancy. Further analysis verifies that firms` financial performance and life cycle can lead to heterogeneous effects. Specifically, the positive impact is more pronounced in firms with lower operational performance and in periods of maturity and recession.

Assessing boro rice yield variances across varied seedling ages to address early flash flood vulnerabilities in the Haor area of Bangladesh

Haor is one of the most flood-prone areas of Bangladesh and it underlies in water for several months of a year. Boro rice cultivation in this area is challenging due to the flash flood. An experiment was conducted to examine the suitability and productivity of four rice varieties transplanted in different seedling ages. This experiment was carried out at Sunamganj district for two consecutive years of Boro season in 2021-22 and 2022-23. Four Boro rice varieties namely Binadhan-10, Binadhan-17, Binadhan-24, BINA dhan25, and three seedling ages (i.e., 30, 35 and 40 days old seedlings) were used as treatment in the experiment. It was conducted through a split-plot design with three replications placing seedling ages in the main plot and crop varieties in the subplot. Transplanting of 30 days seedlings of Binadhan-24 produced the highest mean grain yield of 7.8 t ha-1 and 8.2 t ha-1 while 35 days seedlings produced 7.6 t ha-1 and 7.7 t ha-1 respectively, in two consecutive years, the highest among all varieties. The maturity period among crop varieties varied due to the changes in seedling age as lower seedling age showed an earlier maturity period. So, transplanting of 30-35 days seedlings can be recommended for Binadhan-24 cultivation in the haor area. Bangladesh J. Nuclear Agric, 38(1): 41-52, 2024

Detection of damage caused by Nezara viridula on soybean using novel imaging approaches based on computed tomography and image color analysis.

Soybean (Glycine max L.) is an important leguminous plant, in which pests trigger significant damage every year. Important members of this community are insects with piercing-sucking mouthpart, especially the southern green stinkbug, Nezara viridula L.. This insect with its extraoral digestion causes visible alterations (morphological and color changes) in the seeds. We aimed to obtain precise information about the extent and nature of damage in soybeans caused by N. viridula using nondestructive imaging methods. Two infestation conditions were applied: one with controlled numbers of pests (six insects/15 pods) and another with naturally occurring pests (samples collected from the apical part of the plant and samples from whole plants). An intact control group was also included, resulting in four treatment groups. Seed samples were analyzed by computed tomography (CT) and image color analysis under laboratory conditions. According to our CT findings, the damage caused by N. viridula changed the radiodensity, volume, and shape (Solidity) of the soybean seeds during the pod-filling and maturing period. Radiodensity was significantly reduced in all three damaged categories compared to the intact sample; the mean radiodensity reduction range was 49-412 HU. The seed volume also decreased significantly (25%-80% decrease), with a threefold reduction for samples exposed to regulated damage compared to natural ones. The samples exposed to natural damage showed significant but minor reduction in solidity, while samples exposed to regulated damage showed a prominent decrease (~12%). Image color analysis showed that the damaged samples were well distinguishable, and the differences were statistically verifiable. The achieved data derived from our external and internal imaging approaches contribute to a better understanding of the internal chemical processes, and CT analysis helps to understand the alteration trends of the hidden structure of seeds caused by a pest. Our results can contribute to the development of a practically applicable system based on image analysis, which can identify lots damaged by insects.

Genetic mechanism and petroleum geological significance of calcite veins in organic-rich shales of lacustrine basin: A case study of Cretaceous Qingshankou Formation in Songliao Basin, China

Based on the observation and analysis of cores and thin sections, and combined with cathodoluminescence, laser Raman, fluid inclusions, and in-situ LA-ICP-MS U-Pb dating, the genetic mechanism and petroleum geological significance of calcite veins in shales of the Cretaceous Qingshankou Formation in the Songliao Basin were investigated. Macroscopically, the calcite veins are bedding parallel, and show lenticular, S-shaped, cone-in-cone and pinnate structures. Microscopically, they can be divided into syntaxial blocky or columnar calcite veins and antitaxial fibrous calcite veins. The aqueous fluid inclusions in blocky calcite veins have a homogenization temperature of 132.5–145.1 °C, the in-situ U-Pb dating age of blocky calcite veins is (69.9±5.2) Ma, suggesting that the middle maturity period of source rocks and the conventional oil formation period in the Qingshankou Formation are the sedimentary period of Mingshui Formation in Late Cretaceous. The aqueous fluid inclusions in fibrous calcite veins with the homogenization temperature of 141.2–157.4 °C, yields the U-Pb age of (44.7±6.9) Ma, indicating that the middle-high maturity period of source rocks and the Gulong shale oil formation period in the Qingshankou Formation are the sedimentary period of Paleocene Yi'an Formaiton. The syntaxial blocky or columnar calcite veins were formed sensitively to the diagenetic evolution and hydrocarbon generation, mainly in three stages (fracture opening, vein-forming fluid filling, and vein growth). Tectonic extrusion activities and fluid overpressure are induction factors for the formation of fractures, and vein-forming fluid flows mainly as diffusion in a short distance. These veins generally follow a competitive growth mode. The antitaxial fibrous calcite veins were formed under the driving of the force of crystallization in a non-competitive growth environment. It is considered that the calcite veins in organic-rich shale of the Qingshankou Formation in the study area has important implications for local tectonic activities, fluid overpressure, hydrocarbon generation and expulsion, and diagenesis-hydrocarbon accumulation dating of the Songliao Basin.

Взаимосвязь технофобии и технофилии с интрасубъективными факторами у представителей разновозрастных групп

Introduction. The implementation of “intelligent” systems capable of independently collecting, processing and analyzing information opens up wide opportunities and prospects, but also puts society in front of complex challenges and dilemmas, which is reflected in the attitude of the individual to such systems and technologies. It is important that the active integration of the latest achievements of science and technology into everyday life is commensurate with the psychological readiness of society for appropriate innovative transformations. In this regard, the issue of identifying psychological factors related to an overly open attitude to technology (technophilia) and fear of technology (technophobia) becomes extremely relevant, which will contribute to achieving a balance with regard to new technologies and increasing the reflexivity of society regarding possible technological risks in the near future. The purpose of the empirical study is to study the relationship between technophilia and technophobia in representatives of different age groups with intrasubjective factors. Materials and methods. The study involved 240 respondents aged 20 to 51 years (Mage=31.31; SD=11.54), of which 113 men (Mage=31.87; SD=12.28) and 127 women (Mage=30.81; SD=10.86). The following standardised methods were used: the Schwartz’s PVQ-21 value questionnaire, the A.B. Kupreichenko's methodology "Trust/distrust of personality in the world, self and other people", “Technophilia” and “Technophobia” scales of the attitude to technology questionnaire by G.U. Soldatova et al. Results. The specificity of technophobia and technophilia in representatives of the youthful (20-21 years old) middle (38-51 years old) age is shown. The interrelationships of technophobia and technophilia with intrasubjective factors were established: a person's trust/distrust of himself, other people, the world around him, value profile and personality traits. Predictors of technophobia and technophilia have been identified in men and women of adolescent and middle age (the second period of adulthood). Conclusion. Technophilia and technophobia, which are psychological phenomena of different content, are interrelated with the level of confidence of a person in himself/herself, the world around him/her and other people, value profile and personality traits, and the content of this relationship is revealed taking into account gender and age characteristics.

Comparison of Phenolic Content and Antioxidant Activities of Extracts of Phytolacca americana Plant Based on Some Different Habitats from Türkiye

In this study, leaf and fruit samples of Phytolacca americana collected in the early, mature and senescent period from localities with different habitat characteristics (non-polluted, polluted and wetland) were studied. The total phenolic content, 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging activity and iron (III) reduction antioxidant power (FRAP) of the water and methanol extracts of the samples dried in oven and at room temperature were evaluated and compared as statistically. According to the results of the analyses, the highest phenolic content (263.25 mg GAE/g sample) was found in the leaf parts of the plant collected from the wetland during senescent period, dried at room temperature and extracted with water. The lowest phenolic content (0.22 mgGAE/g sample) was determined in water extract of the fruit parts of the plant collected from the same locality in the same period. Among the antioxidant activity values determined the highest and lowest findings belong to the samples. It can be concluded that each tested variable is statistically significant for both the leaf and fruit part, and by bringing these variables under suitable conditions, biochemically more efficient use of plants can be achieved.

IMPACT OF NITROGEN SOURCES ON THE PERFOMANCE OF LOWLAND RAINFED RICE AT EDOZHIGI IN THE SOUTHERN GUINEA SAVANNA OF NIGERIA

Field trials were conducted at Edozhigi, in the southern Guinea savanna of Nigeria during the 2020 and 2021 cropping seasons to determine the response of lowland rainfed rice to two Nitrogen sources (urea super granule (USG) and granular urea (GU)). There treatments consisted of five levels of USG (80, 90, 100, 110, 120 kg N ha-1) and six levels of GU (40, 80, 90, 100, 110, 120 kg N ha-1) and a control (0). The 12 treatments were laid out in a randomised complete block (RCBD) with three replicates. Result of the physical and chemical analysis of soil of the experimental field revealed that, soil had sandy clay loam texture with slightly acidic soil reaction. The soil organic carbon, total N, available P, exchangeable cataionic nutrients were all low in the soil which make the soil to have low fertility. Result of the study indicated that, plant growth and maturity period were not significantly affected by the application of N. The result further shows a significant response to application of USG, but not to GU. The highest paddy yield of 4.53 Mg ha-1 was recorded for USG at 90 kg N ha-1 which was significantly higher than that of the control and the GU treatments, but statistically similar to most of the other USG treatments. The USG is recommended as a source of N for the enhancement of the paddy yield.

Enhancing growth and yield attributes through bio priming approach in direct seeded rice

Sowing pregerminated and primed rice seeds was found to be advantageous in shortening the numbers of emergence, heading, and maturity days. Reduction in the maturity period of rice by 14.1 days is a significant phonological achievement. Therefore, to ensure the benefits of seed enhancing techniques on seed yield and yield components of rice (Oryza sativa L.),field experiment was conducted in Split Plot Design with four replications using PMK(R)4 with fourteen different seed biopriming liquid microbial cultures and its combinations. The results showed that the seeds soaked in equal volume of liquid microbial cultures Azospirillum+ Phosphobacteria 20% for 18hrs recorded maximum plant height at 45(29.2cm), 90DAS(105.2 cm) and harvest stages (113.3 cm). The leaf area index(10), number of productive tillers, panicle length(36.3 cm), number of spikelets per panicle (106) and panicle weight were maximum in co-inoculated priming treatment Azospirillum + Phosphobacteria and Azospirillum+ Phosphobacteria+ Silicate Solublizing Bacteria followed by Azosprillium 20% for 18hrs and minimum with non-primed seeds. Combined application of Azospirillum + Phosphobacteria was found to be most effective treatment in improving seed yield per plot(6.6g), seed yield per hectare and 1000 seed weight (24.72 g) over non-primed seeds.

Effect of Delayed Irrigation at the Jointing Stage on Nitrogen, Silicon Nutrition and Grain Yield of Winter Wheat in the North China Plain.

Water scarcity is a key limitation to winter wheat production in the North China Plain, and it is essential to explore the optimal timing of spring irrigation to optimize N and Si uptake as well as to safeguard yields. The aim of this study was to systematically study the effect mechanism of nitrogen and silicon absorption of winter wheat on yield under spring irrigation and to provide a scientific basis for optimizing irrigation strategy during the growth period of winter wheat. In this experiment, the winter wheat 'Heng 4399' was used. Five irrigation periods, i.e., 0 d (CK), 5 d (AJ5), 10 d (AJ10), 15 d (AJ15), and 20 d (AJ20) after the jointing stage, were set up to evaluate the nitrogen (N) and silicon (Si) absorption and grain yield (GY). The results showed that delayed irrigation for 5-10 days at the jointing stage had increased the GY. With the delay of irrigation time, the N/Si content of the entire plant at the maturity period increased first and then decreased; among that, the maximum N contents appeared in AJ15 and AJ5 in 2015 and 2020, respectively, while the Si concentrations appeared in AJ5 and AJ10 in sequence. Compared with AJ15 and AJ20, the N accumulation of vegetative organs in AJ5 increased by 3.05~23.13% at the flowering stage, 14.12~40.12% after the flowering stage, and a 1.76~6.45% increase in the N distribution rate at maturity stage. A correlation analysis revealed that the GY was significantly and positively correlated with the N/Si accumulation at the anthesis and N translocation after the anthesis stage. In conclusion, under limited irrigation conditions, delaying watering for 5 to 10 days at the jointing stage can improve the nitrogen and silicon absorption and nutrient status of wheat plants and increase wheat yield.
