Background: Anastomotic biliary strictures (BSs) are among the most common complications after liver transplantation (LT), accounting for 5–15% of adult recipients after deceased-donor transplantation. For some reason, this percentage increased in our center in recent years, and the goal of this study was to find out the reasons behind this to avoid this complication in the future. Material and Methods: We retrospectively analyzed the occurrence of anastomotic biliary strictures in 230 cadaveric-donor LTs performed in our center between January 2019 and December 2023. Many variables related to the donor, recipient, and surgical procedure were compared between patients who experienced BS and those without this complication. Statistical analysis was performed using Fisher’s exact test, a one-way ANOVA test, and Pearson’s correlation coefficient. Results: Altogether, 51 patients (22.17%) developed BSs. This percentage was especially high in 2023 (32%). The only significant differences found in study group compared to the control group were the requirement of additional doses of vasopressors during surgery (45 (86.53%) vs. 138 (77.09%), p = 0.0001) and more frequent instances of reperfusion syndrome (8/51 (15.68%) vs. 11/179 (6.11%), p = 0.00001). Conclusions: We conclude that ischemia during LT has an advantage over technical parameters in the development of BSs after LT. Appropriate blood volume resuscitation as opposed to inotropic treatment may reduce the risk of this complication.

Published: February 2025

Marine organisms produce sounds for various purposes, including spawning, avoidance, and migration, with each species exhibiting unique acoustic characteristics. This study observed the grunt sounds of Pacific cod (Gadus macrocephalus) during the spawning season for the first time using passive acoustic monitoring (PAM) techniques. Acoustic signals were recorded continuously for about one month at an aquaculture fish farm in Korea. From these recordings, 1208 grunt sounds of Pacific cod were extracted using an automatic grunt detector, and statistical time–frequency parameters were estimated. On average, the grunt sounds consisted of 29 pulses at 6.5 ms intervals within a duration of 205 ms, with a pulse rate of 122.6 per second. The periodic pulse-type signal creates multiple harmonic frequencies on the spectrogram, characterized by time-harmonic modulation with a slope of −240 Hz/s. The mth harmonic frequency distribution ranged from 162 to 822 Hz, with a median source level of 122.6 dB re 1 μPa at 1 m. These findings provide essential scientific data for understanding Pacific cod communication during the spawning season and can aid in identifying spawning sites, conserving habitats, and managing biological resources, contributing to marine ecosystem protection and sustainable management.
Approximate Description of Indefinable Granules Based on Classical and Three-Way Concept Lattices
Authors: Wang Hongwei , Zhi Huilai , Li Yinan
Published: February 2025

Granule description is a fundamental problem in granular computing. However, how to describe indefinable granules is still an open, interesting, and important problem. The main objective of this paper is to give a preliminary solution to this problem. Before proceeding, the framework of approximate description is introduced. That is, any indefinable granule is characterized by an ordered pair of formulas, which form an interval set, where the first formula is the β-prior approximate optimal description and the second formula is the α-prior approximate optimal description. More concretely, given an indefinable granule, by exploring the description of its lower approximate granule, its β-prior approximate optimal description is obtained. Likewise, by consulting the description of its upper approximate granule, its α-prior approximate optimal description can also be derived. Following this idea, the descriptions of indefinable granules are investigated. Firstly, ∧-approximate descriptions of indefinable granules are investigated based on the classical concept lattice, and (∧,∨)-approximate descriptions of indefinable granules are given via object pictorial diagrams. And then, it is revealed from some examples that the classical concept lattice is no longer effective and negative attributes must be taken into consideration. Therefore, a three-way concept lattice is adopted instead of the classical concept lattice to study (∧,¬)-approximate descriptions and (∧,∨,¬)-approximate descriptions of indefinable granules. Finally, some discussions are presented to show the differences and similarities between our study and existing ones.

Published: February 2025

Laser powder bed fusion (L-PBF) is a widely used additive manufacturing technique that enables the creation of complex lattice structures with applications in biomedical implants and aerospace components. This study investigates the impact of relative density and the geometric parameters (unit cell size and strut diameter) of body-centred cubic (BCC) lattices on the compressive mechanical properties of Ti-6Al-4V (Ti64) lattices manufactured using continuous wave L-PBF. The as-built and heat-treated samples were evaluated for their Young’s modulus, strength, and ductility. Lattices with varying unit cell sizes (1–3 mm) and strut diameters (0.3–1.2 mm) were fabricated, resulting in relative densities ranging from 10% to 77%. All of these samples exhibited a 45° shear failure, which was attributed to the alignment of the principal stress planes with the lattice struts under compression, leading to shear band formation. This study provides critical insights into the interplay between geometric parameters, microstructure evolution, and resultant mechanical properties, contributing to the experimental validation of solid vs. lattice samples fabricated under identical conditions. Fractography analysis revealed that the as-built samples exhibited predominantly brittle fracture characteristics, while heat-treated samples displayed mixed fracture modes with increased ductility. Results indicate that heat treatment enhances mechanical properties, yielding comparable compressive strength (approx. 20% decrease), a reduced modulus of elasticity (approx. 30% decrease), and increased ductility (approx. 10% increase). This is driven by microstructural changes, such as the phase transformation from α’ martensitic needles to α + β, and thus relieves the residual stress to some degree. By addressing the microstructure–property correlations and failure mechanisms, this work establishes guidelines for optimizing lattice designs for biomedical and aerospace applications, emphasizing the critical role of geometric parameters and thermal treatment in tailoring mechanical behaviour.

Published: February 2025

Two bis-ruthenium(II) complexes, namely N,N′-{5,17-diamino-4(24),6(10),12(16),18(22)-tetramethylenedioxy-2,8,14,20-tetrapentylresorcin[4]arene}-bis-[dichloro-(p-cymene)-ruthenium(II)] (1) and N,N′-{5,11-diamino-4(24),6(10),12(16), 18(22)-tetramethylenedioxy-2,8,14,20-tetrapentylresorcin[4]arene}-bis-[dichloro-(p-cymene)-ruthenium(II)] (2) were synthesized and tested as catalysts in the N-alkylation of primary amines with arylmethyl alcohol using the green “hydrogen borrowing” methodology. The catalytic results were compared with those obtained when the N-{5-amino-4(24),6(10),12(16),18(22)-tetramethylenedioxy-2,8,14,20-tetrapentyl-resorcin[4]arene}-[dichloro-(p-cymene)-ruthenium(II)] (3) complex was employed as catalyst. The rate of the N-alkylation of aniline with benzyl alcohol increased in the order 3 < 1 ≪ 2, which highlights the importance of the relative positioning of the two metal centers on the upper rim of the resorcin[4]arene. Theoretical investigations suggest that the grafting of the two “RuCl2(p-cymene)NH2” moieties on two distal aromatic rings of the cavitand allows a cooperative effect between a ruthenium atom and the coordinated amine of the second metal center.
Magnesium and Migraine

Published: February 2025

Migraine is a widespread and intricate neurological condition that involves various factors and is marked by recurring headache episodes. Migraine is among the ten neurological conditions accounting for the greatest disability in the whole population, the leading cause of disability for children and adolescents aged 5–19 years, and the second cause of disability for adults aged 20–59 years. Magnesium deficiency is also a very common condition resulting from diverse reasons, including insufficient dietary consumption or increased loss through the gastrointestinal or renal system. Accumulated evidence from case reports, case–control studies, observational studies, and randomized, placebo-controlled trials has shown the effectiveness of magnesium supplementation in alleviating migraine, both acutely and chronically. Mechanisms that may help explain these results include the potential link between magnesium deficit and spreading cortical depression, vascular changes, oxidative stress, chronic inflammation, nervous excitation, neurotransmitter release, and electrolyte imbalances. This article aims to provide a comprehensive review of the available evidence on the links between magnesium and migraine, considering the role of magnesium in the pathogenesis of migraine and the utility of magnesium in its prevention and treatment.

Local Sub-Block Contrast and Spatial–Spectral Gradient Feature Fusion for Hyperspectral Anomaly Detection
Authors: Zhao Dong , Xu Xingchen , You Mingtao , Arun Pattathal V. , Zhao Zhe , Ren Jiahong , Wu Li , Zhou Huixin
Published: February 2025

Most existing hyperspectral anomaly detection algorithms primarily rely on spatial information to identify anomalous targets. However, they often overlook the spatial–spectral gradient information inherent in hyperspectral images, which can lead to decreased detection accuracy. To address this limitation, we propose a novel hyperspectral anomaly detection algorithm that incorporates both local sub-block contrast and spatial–spectral gradient features. In this approach, a grid block window is utilized to capture local spatial information. To effectively detect low-contrast targets, we introduce a novel local sub-block ratio-multiply contrast method that enhances anomalous regions while suppressing the background. Additionally, to mitigate the challenges posed by complex backgrounds, a feature extraction technique based on spatial–spectral gradients is proposed. To account for the spectral reflectance differences between anomalous targets and the background, we further introduce a local sub-block ratio-difference contrast method to compute preliminary detection scores. The final anomaly detection results are obtained by merging these two detection scores. The key advantage of the proposed method lies in its ability to exploit local gradient characteristics within hyperspectral images, thereby resolving the issue of edge features being misidentified as anomalies. This method also effectively reduces the impact of noise on detection accuracy. Experimental validation based on four real-world datasets demonstrates that the proposed method outperforms seven state-of-the-art techniques, showing superior performance in both qualitative and quantitative evaluations.
Performance Boundaries and Tradeoffs in Super-Resolution Imaging Technologies for Space Targets
Authors: He Xiaole , Liu Ping , Wang Junling
Published: February 2025

Inverse synthetic aperture radar (ISAR) super-resolution imaging technology is widely applied in space target imaging. However, the performance limits of super-resolution imaging algorithms remain largely unexplored. Our work addresses this gap by deriving mathematical expressions for the upper and lower bounds of cross-range resolution in ISAR imaging based on the computational resolution limit (CRL) theory for line spectrum reconstruction. Leveraging these explicit expressions, we first explore influencing factors of these bounds, including the traditional Rayleigh limit, number of scatterers, and peak signal-to-noise ratio (PSNR) of the scatterers. Then, we elucidate the minimum resource requirements in ISAR imaging imposed by CRL theory to meet the desired cross-range resolution, without which studying super-resolution algorithms becomes unnecessary in practice. Furthermore, we analyze the tradeoffs between the cumulative rotation angle, radar transmit energy, and other factors that contribute to optimizing the resolution. Simulations are conducted to demonstrate these tradeoffs across various ISAR imaging scenarios, revealing their high dependence on specific imaging targets.

Authors: Byeon Chul-Woo , Kim Joon-Hyung
Published: February 2025

This paper presents a high-power heterojunction bipolar transistor (HBT) power amplifier (PA) module designed for GSM/EDGE applications. The proposed HBT PA employs a differential output stage that delivers high output power at a low supply voltage. A transformer-based output matching network is employed to combine the differential output signals. Through the selection of an appropriate capacitor value at the transformer’s center tap, linearity is enhanced across a wide bandwidth without requiring additional second harmonic termination. When assembled with a low-pass filter and an antenna switch, the PA module achieves an output power of 36 dBm and a power-added efficiency (PAE) exceeding 40% in GSM mode. In EDGE mode, it delivers an output power of 28.5 dBm with a PAE exceeding 20%. Additionally, the designed PA module achieves an adjacent channel power ratio of −60 dBc at a 400 kHz offset with an output power of 28.5 dBm.
Modeling and Performance Analysis of Uplink Laser Transmission Across Sea Surfaces: A Channel Characterization Study
Authors: Gao Hong , Zhang Tinglu , Yuan Ruiman , Hu Lianbo , Chen Shuguo
Published: February 2025

Variable marine environmental conditions, particularly at the sea surface, present considerable challenges to cross-media laser transmission. This study simulates uplink laser transmission through a seawater–sea surface–air channel via ray tracing and Monte Carlo methods, with an emphasis on the impacts of the sea surface channel. A spatial model of the sea surface is introduced, which uses a wave spectrum and fast Fourier transform technology, and the results are compared against those of a classical statistical model. The validity and applicability of six representative wind wave spectra are assessed for their effectiveness in characterizing the optical sea surface. Among these spectra, the Elfouhaily spectrum, which is refined for low-wind conditions, can most accurately represent the optical properties of the sea surface. The simulations reveal that the spatial model captures power fluctuations due to dynamic sea surface changes. At shorter underwater transmission distances, the spatial model may induce considerable drift, thereby degrading power estimates, where the difference is about 0.9 dB compared with the statistical model. Deeper underwater transmissions can mitigate beam distortions, resulting in a decrease in normalized peak power from −114 dB to −157 dB. Additionally, the laser centroid distribution tends to be elliptical because of the distribution of the sea surface azimuth. These findings underscore the importance of incorporating spatiotemporal dynamics in modeling sea surfaces and provide insights for optimizing underwater air laser transmission links in complex marine environments.

Authors: Pandey Anubhav Kumar , Jadoun Vinay Kumar , Sabhahit Jayalakshmi N. , Sharma Sachin
Published: February 2025

A virtual power plant (VPP) is a potential alternative that aggregates the distributed energy resources (DERs) and addresses the prosumer’s power availability, quality, and reliability requirements. This paper reports the optimized scheduling of an interconnected VPP in a multi-area framework established through a tie-line connection comprising multiple renewable resources. The scheduling was initially performed on a day ahead (hourly basis) interval, followed by an hour ahead interval (intra-hour and real time), i.e., a 15 min and 5 min time interval for the developed VPP in a multi-area context. The target objective functions for the selected problem were two-fold, i.e., net profit and emission, for which maximization was performed for the former and reduction for the later, respectively. Since renewables are involved in the energy mix and the developed problem was complex in nature, the proposed multi-area-based VPP was tested with an advanced nature-inspired metaheuristic technique. Moreover, the proposed formulation was extended to a multi-objective context, and multiple scheduling strategies were performed to reduce the generated emissions and capitalize on the cumulative profit associated with the system by improving the profit margin simultaneously. Furthermore, a comprehensive numeric evaluation was performed with different optimization intervals, which revealed the rapid convergence in minimal computational time to reach the desired solution.

Published: February 2025

This study explores the determinants of job satisfaction among IT industry employees in the U.S. and South Korea, focusing on how cultural and socio-economic contexts influence employee well-being and organizational sustainability. Given the high turnover rates in the IT industry, understanding the key factors affecting job satisfaction and dissatisfaction is critical for promoting sustainable organizational practices. By comparing reviews from Glassdoor and Jobplanet, this study uncovers cultural and organizational differences that directly affect employee retention and job satisfaction, offering actionable insights for multinational IT companies seeking to align their strategies with sustainable HR practices. The research utilizes Contextualized Topic Modeling (CTM), a cutting-edge method leveraging Sentence-BERT embeddings, to analyze user-generated reviews. CTM identifies key topics such as attendance management, career development, organizational culture, welfare support, salary, and job autonomy, revealing distinct cultural influences. For example, attendance management and organizational culture positively influenced job satisfaction in U.S. companies, while welfare benefits were more significant in the U.S. than in South Korea. Salary had a positive effect in South Korea but a negative effect in the U.S. The comparative analysis also highlights the higher satisfaction levels among current employees, underscoring factors critical for long-term retention. This study contributes to the literature by leveraging user-generated content to reveal context-specific factors, including new elements such as “technological capabilities” and “location and accessibility,” which are often overlooked in traditional survey-based research. The findings provide actionable insights for IT companies to refine HR practices in ways that enhance employee satisfaction, contributing to both organizational sustainability and the well-being of employees.

Published: February 2025

Grasping the effective carrying capacity of airport hub subway stations in real-time serves as the foundation for enhancing the safety assurance capability of the hub. Starting from the perspectives of multiple subsystems, including people, stations, and trains, and combining passenger flow, system structure, and multiple attributes of trains, a system dynamics (SD) model for passenger travel in airport hub subway stations is established. The model is simulated using Vensim PLE 5.9d to analyze the effective carrying capacity of the transfer system under the existing configuration and layout of transfer facilities and equipment in the hub. The model features a modular architecture and interface, enabling quick and easy model establishment, and adapts to various configurations and operational characteristics of airport hub subway stations in a user-friendly manner. Multiple sensitivity simulation analysis experiments are designed to analyze changes in passenger flow density from multiple perspectives. This method can calculate the effective carrying capacity of airport hub subway stations, providing a scientific basis for planning, construction, and operational management. The effectiveness of the model is verified by analyzing the Pudong International Airport terminal subway station.
The Impact of DSO Grid-Integration Measures on EV Users in Germany
Authors: Ganz Kirstin , Vollmuth Patrick
Published: February 2025

As the share of electric vehicles (EVs) continues to rise, the distribution grid faces the risk of overload. In Germany, the reform of § 14a Energiewirtschaftsgesetz (German Energy Industry Act, EnWG) was introduced to address this problem. The reform has changed the revenue potential of smart chargeable uni and bidirectional EVs (smart EVs). The reform introduces variable grid fee tariffs for smart EVs, but also possible emergency power reduction measures to relieve grid overload situations. While variable grid fee tariffs can increase revenues, power reduction measures can lead to revenue losses. This work investigates the dual impact of these factors by implementing variable grid fee tariffs and the option of power reduction signals in a flexibility marketing model. Our findings indicate that smart EVs can generate significant additional revenues through variable grid fee tariffs in 2035. Conversely, the impact of emergency power signals on these revenues and the EV load profile is marginal. As a result, the effect of power reduction measures on the German load profile is also negligible.

Authors: Kraus David , Baumann Daniel , Vučinić Veljko , Sax Eric
Published: February 2025

Modern mobility faces increasing challenges, like carbon-free transportation and the need for flexible transportation solutions. The U-Shift II project addresses these problems through a modular electric vehicle architecture, a drive unit (Driveboard) and a vehicle body (Capsule). This separation offers high flexibility in different use cases. Current architecture paradigms, like AUTOSAR, face limitations in cost and development speed. To address these issues, this paper introduces a hybrid software architecture that integrates signal-oriented architecture (e.g., CAN bus) with service-oriented architecture for enhanced flexibility. A integral component of the hybrid architecture is the dynamic link system, which bridges these architectures by dynamically integrating Capsule-specific components into the Driveboard software stack during runtime. The performance of the developed systen and its functionality were evaluated using a hardware setup integrated into a Driveboard prototype. The dynamic link aystem was evaluated including latency measurements, as well as functionality tests. Additionally, a cloud-based reconfiguration process enhances the versatility of the Driveboard by allowing for over-the-air software updates and resource allocation. The results show a promising hybrid, reconfigurable E/E architecture that aims to enable a robust transition towards a pure service-oriented architecture required in future electric autonomous vehicles.

Authors: COLLARES CARLOS FERNANDO
Published: February 2025

This satirical essay outlines ten ironic commandments designed to highlight flaws in current medical education practices. Through exaggerated emphasis on rote memorization, neglect of clinical reasoning, and prioritization of grades over true understanding, the essay critiques practices that foster superficial knowledge and professional stagnation. Additional commandments target the culture of burnout, disregard for teamwork, resistance to change, and ignoring social determinants of health. The essay underscores the detrimental effects of focusing solely on short-term performance, arbitrary standards, and cross-sectional assessments. By adhering to these commandments, medical institutions ensure a generation of physicians ill-prepared for the complexities of modern healthcare, ultimately compromising patient safety. The essay calls for comprehensive reform, advocating for a more holistic, collaborative, and adaptive approach to medical education.
Espacialização e subjetivação
Authors: De Moraes Servilha Mateus
Published: February 2025

This work consists in a study of the social processes that produce, inseparably, spatializations and subjectivities. The objective of this article is to reflect, from discourses and practices articulated around the idea of region, the subjectivation as constituted and constituent of space division processes. Starting from a dialogue with the bourdieuan principles of vision and division, we analyzed spatial delineations, at multiple scales, that border and classify subjects, generally based on a taxonomic and stigmatizing rationality. The formation and development of the modern nation-state is analyzed in the work through two central contradictions: the production of identity unity in contrast to continuous spatial and social division and the definition of the subject as protagonist of national identity and its denial through a process of subalternized subjection-objectification. The recognition of the subject as a fundamental movement for contemporary science, including Geography, is debated from the understanding of the indispensable inclusion of subjectivation in analyses of spatializations, as well as from the elaboration of geographical reflections that are crossed by the (re)elaborations produced by subjectivized groups through the discursive and practical dispute of the meanings present in the then naturalized spatial divisions.

Published: February 2025

Purpose: This study aims to examine communication patterns at Murni Teguh Rosiva Mother and Child Hospital (RSIA) in Medan, focusing on the effectiveness of organizational communication models as outlined by Fred C. Lunenburg, including chain, wheel, circle, Y, and all-channel communication structures, in supporting coordination, responsiveness, and healthcare service quality.
Methodology/approach: A qualitative approach was employed, involving in-depth interviews and participatory observation with both medical and non-medical staff. Data collection focused on analyzing communication patterns within the hospital setting.
Results/findings: The study revealed that each communication model presents unique strengths and limitations in facilitating information flow and decision-making processes. The chain and wheel models support structured information distribution but often result in delays during critical situations. The circle and Y patterns enable faster inter-unit collaboration but are susceptible to miscommunication due to varying professional backgrounds. The all-channel pattern in informal communication fosters staff solidarity but risks the spread of inaccurate information.
Limitations: This study is limited to observational and interview-based data from a single healthcare institution, potentially restricting generalizability across different healthcare settings.
Contribution: This research contributes to the development of a more responsive and collaborative communication system in healthcare institutions, particularly in enhancing operational support through adaptive communication frameworks.

Echinococcosis is endemic in Mediterranean countries, with the lungs and liver being the most affected organs in childrens. Primary biliary tract hydatid cyst is an exceptional localization. A 4-year-old child was referred to our surgical outpatient department due to suspicion of a DKC, based on right upper quadrant abdominal pain accompanied by jaundice. Physical examination revealed mild tenderness in the right upper quadrant of the abdomen. An ultrasound complited with an MRI described a Todani type 4 choledochal cyst. The patient underwent right subcostal laparotomy, during which exploration revealed a cystic formation of the choledochus from which clear fluid was aspirated. Upon opening the cyst, a proligere membrane was found, confirming the diagnosis of choledochal hydatid cyst. Primary hydatid cyst of the bile ducts is an extremely rare entity, which is why radiologists do not consider this diagnosis to be primary.

Methylene blue (MB) staining has been studied in various gastrointestinal organs over the past years. We present two cases of esophagogastroduodenoscopy and endoscopic ultrasound –guided MB injection to facilitate therapeutic upper endoscopic interventions. The first case reports a 10% diluted MB injection to facilitate pancreatic duct orifice localization and cannulation after multiple unsuccessful attempts with endoscopic retrograde cholangiopancreatography, and the second case reports a 10% diluted MB injection to identify gastric staple line fistula. The untraditional use of MB in both cases helped achieve a successful intervention and improved patients’ outcomes after significant delays relying on the traditional methods. The two cases highlight the feasibility of MB as an adjunct in upper endoscopic interventions.
HMPV Virus and China: Debunking Myths and Misinformation

The recent surge in human metapneumovirus (HMPV) cases in China has triggered global concern, raising critical questions about its public health implications and the geopolitical narratives shaping discussions around its origin and spread. As the world navigates this outbreak, two pivotal questions arise: Is China responsible for the spread of HMPV? And why is China being blamed? These inquiries warrant a measured, evidence-based analysis, free from the politicization that has too often distorted global health discussions. HMPV is an acute respiratory virus known to cause symptoms similar to those of the common cold or flu (Jamil et al., 2025). It is neither a new pathogen nor a uniquely Chinese phenomenon. Despite the absence of a vaccine, HMPV has circulated in human populations for decades, with periodic outbreaks occurring across different regions (Gandhi et al., 2022). Recent reports indicate a localized rise in cases within China, but it is important to contextualize these trends. It was clarified that these cases align with seasonal patterns typical of respiratory infections in the northern hemisphere during winter (Kuang et al., 2024). Despite these facts, unfounded allegations have emerged, accusing China of engineering HMPV as a bioweapon—an accusation eerily reminiscent of the misinformation campaigns during the COVID-19 pandemic. These claims lack scientific merit and fail the test of logical scrutiny. Historically, pandemics and outbreaks have been met with blame and scapegoating rather than a commitment to collective responsibility. However, past experiences—most notably during COVID-19— underscore the dangers of politicizing health crises. Misinformation erodes trust in science and public health institutions, delaying effective responses and exacerbating human suffering.

Goal. Selection of collection strains to create a stable association of microorganisms, which will serve as the basis of a new complex drug against gall and cyst-forming nematodes.
Methods. A complex of generally accepted methods and methodical approaches was applied for the screening of collection strains with nematophagous efficiency.
Results. Eight collection microorganisms were screened in laboratory conditions. Five strains of fungal etiology with nematicidal activity against cyst-forming and gall nematodes were selected for further research. The relationships, viability, dynamics of growth and development of potential biological control agents of phytoparasitic nematodes on agarized nutrient media were studied.
Conclusions. During joint cultivation of the investigated microorganisms on agarized nutrient media, it was established that Orbilia oligospora, Hirsutella rhossiliensis, Metаrhizium anisopliae, Purpureocillium lilacinus, Metacordyceps chlamydosporia strains do not exhibit antagonistic properties and can be used to create a stable association of microorganisms with nematocidal activity.

Goal. Clarification of the species composition of cruciferous fleas and cryptid beetles in the rape agrocenosis of the winter Left Bank Forest Steppe of Ukraine.
Methods. Field — monitoring of phytophages using a Petlyuk box and yellow trap cups was carried out at the State Enterprise «Experimental Farm «Takhtaulovo» of the Institute of Plant Protection of the National Academy of Sciences of the Poltava District of the Poltava Region during 2023—2024; laboratory — identification of pests in the pesticide application technology laboratory of the Scientific Research Institute of the National Academy of Sciences.
Results. During surveys during the recovery period of winter rapeseed vegetation in 2023—2024, it was established that crops of the crop were inhabited by cruciferous fleas and hidden caterpillars. During this period, culture plants were in the stemming phase. The species composition of cruciferous fleas in the agrocenosis of the culture was formed from the following species: black (Phyllotreta atra F.), blue (Ph. nigripes F.), wavy (Ph. undulata Kutsch.), light-footed (Ph. nemorum L.) and notched (Ph. striolata F.). In the agrocenosis of winter rape during the years of research, the black flea dominated, the share of which reached 70.8% of the total amount. At the same time, blue and wavy plates accounted for 26.9% of the total collection. Also, other types of these phytophages were found in crops, but their number was quite low in the spring period. During the period of recovery of winter rape vegetation, it was found that the agrocenosis of winter rape was dominated by cruciferous sedum and large rape sedum, the share of which was 80.5% of the total number. Also, the activity of the cabbage stem and rape seed borers was noted on the crops, and their number was much lower than the total and reached only 11.6% and 7.9%, respectively.
Conclusions. It was established that the dominant species on winter rapeseed crops during the years of research among the complex of cruciferous scales of the Phyllotreta family were black (Phyllotreta atra F.) and blue (Ph. nigripes F.) — 97.7%, and among the complex of cryptoctopus of the Ceutorhynchus family were cruciferous — C. picitarsis Gyll. and large rape — C. napi Gyll., the share of which reached 80.5% of the total collection.
