The systemic concept of formation and the problem of species
Authors: Malikov V.G. , Golenishchev F.N.
Published: October 2022

This concept of formation is quite similar to epigenetic one. The biological integrity is considered as an all-round concordance between constituents of structure, functioning, reacting and development, while an organism is seen as a dynamic-steady system of integrative relations between genome and phenome based on mutual influence. Any transformation or emergent self-organization within a living system is connected with the maintenance of its steady state. The adaptive constituent of the system’s steady state concerns to its fitness, and the structural constituent – to its steady-state structure. The only difference between ontogenesis and formation is that the object of the first one is an organism, while the object of the second one is a reproducing totality of organisms, which is elementary in the frame of typology and historically conditioned within a definite space. A species is considered as typologically indivisible and historically unrepeatable variant of steady relations between genome and phenome, which canalize the diversity of their own systemically permitted transformations. The «epigenetic» constituent of divergence between species is determined by difference in relations between phenome and genome, not by change of the latter’s compound. The «products» of epigenetic speciation distinctly differ in morphology and ecology, having a lack of post-zygotic reproductive isolation. The reproductive isolation between them is caused by ecological and ethological barriers. The genetic constituent of divergence between species is incompatibility between nonconspecific genomes, which more often is revealed in a form of hybrids sterility. The prevailing of the genetic constituent of interspecific divergence is caused by allopatrie in uniform environmental conditions. In such case, the genomic divergence is accompanied by invariable relations between genome and phenome, that determines morphological and ecological uniformity of cryptic species. The divergence between panmictic species more often includes both of the constituents in different ratio. Due to its universality, the systemic approach to the problem of species is also appropriate to apomictic organisms.
The pecularities of flowering plants speciation
Authors: Kamelin R.W.
Published: October 2022

Among the fundamental distinctions between plants and animals at the different levels of organization of the plant kingdom it is especially important distinctions on a population – species level of organization. This is a higher-order variety of racial structures or «eidologic» units typical of plants in connection with multiplicative processes as hybridization and specific features of biological isolating mechanisms of races (and species), polyploidy of different origin, agamic-and clonal types of asexual breeding etc. After the brief historical review of botanical works on these problems it is emphasized, what of diversity of plants the nature of micro-evolutionary transformations to populations has unequal basis (where frequently populations considerably hybrid breakdown, two ore more species etc.) and, actually, the speciation. Basic natural units of evolutionary process at plants are not only species (mono- or polytypical), but also it is long existing complexes of populations of the different species, interacting with each other (down to complex of syngameons uniting species of a genus or even different genera). The first who has definitely distinguished species and species-complexes was Wladimir Komarov. Now it is possible to distinguish at vascular plants some types of species (up to 7), and species-complexes (i.e. the basic eidological units, it is real evoluting in the nature). Consequently it is possible to discuss about the greater potentiality for evolutionary transformations for a vascular plants, than one at a vertebrate animals.
Pattern of morphological variety of angeospermous pollen aperture distribution and natural ordering of biological variety, or – what is a variety (problems of description and interpretation)
Authors: Pozhidaev A.E.
Published: October 2022

Beside typical pollen forms with symmetrical aperture arrangement, various deviant forms with less symmetrical arrangements have been observed in remote Angiospermous taxa. The pollen forms may be arranged in the continuous, geometrically regular and taxonomically unspecific transformational series. Continuous and regular pattern of the variety obtained can not be described by any way of the classification without complete destroying of the unity of this pattern due to the typological procedures (discretization). The paradox is considered: the variety described consists of discrete pollen grains (as the biological variety consists of mortal living bodies) i.e. has the discrete pattern, but the variety of pollen morphological characteristics have the continuous pattern. Problems of description of the pattern of the biological variety and ways of interpretation are discussed.

This study reports the viewpoints of students on Emergency Remote Teaching (ERT) in tertiary institutions in Nigeria during the COVID-19 induced schools’ closure. Three research questions guided the study. The descriptive survey design was adopted. A total of 1017 students formed the population for the study. Sample size of 100 students were drawn using simple random sampling technique. A 32 item structured questionnaire titled ‘Students’ View on Emergency Remote Teaching (SVERT)’ validated by experts with a reliability coefficient of 0.78 was used as instrument for data collection. Data was analysed using frequency, percentage and mean. The findings revealed the educational media used by NAU and KSU lecturers for ERT. It further revealed that students were satisfied with the coverage of course contents, but not fully satisfied with ERT due to inadequacy of learning activities, which led to boredom amongst isolated learners. It also found out that challenges experienced during ERT include high cost of data for internet subscription, inadequate electricity supply to keep device always charged before lectures, among others. The study recommended among others that ERT sessions should be designed with relevant and highly engaging and interactive learning activities to reduce boredom among isolated learners during learning.

Introduction: This report shows the outcomes and lessons learnt from a 3-month intervention focused on decentralization of COVID-19 coordination, testing and contact tracing activities in three hotspot local government areas (LGAs) of a state in the southwest of Nigeria. Methods: A description of COVID-19 outbreak response from the occurrence of the index case was documented. A health facility and community-based intervention implemented in three hotspots LGA as part of response to COVID-19 pandemic from 24th May to 22nd August, 2021 was described. The interventions implemented focused on integrating COVID-19 testing into routine healthcare services in 103 health facilities, engagement of community-based volunteers to conduct contact tracing, and improving coordination of the response through the conduct of incident management meetings at state and LGA levels.  The COVID-19 dataset from 22nd February to 22nd August, was obtained from the State Ministry of Health and analyzed. Data were summarized using charts and maps. Results: A higher number of cases (3879) were tested between 24th May to 22nd August, 2021 (during intervention) compared to 1667 cases tested between 23 February to 23 May, 2021 (before intervention) across the three LGAs. Generally, there was a decline in the cumulative number of contacts traced and line-listed during the intervention (778) compared to the period before the intervention (1170) in two of the three LGAs. The number of weekly incident management meetings held improved by 25% at State level, while 83% of weekly LGA meetings were held at the three hot spot LGAs during the intervention compared to the period before the intervention, where no meeting was held at LGA level. Conclusions: The decentralization of the COVID-19 outbreak response from a central approach to the LGA level improved only testing numbers and the number of incident management meetings conducted across the three hot spot LGAs. The number of contacts line-listed, positivity rate and reported cases reduced following the interventions. The need to supplement contact tracing activities using information technology for self-report as done in other climes, as well as engaging community, religious leaders and key community groups as integral members of the contact tracing team was emphasized.
Economic Aspects of the Quality of Life
Authors: Decyk Kamil , Rzeszutek Andrzej
Published: October 2022

The aim of the research was to identify and assess the economic aspects of the quality of life in the EU. The research covered all Member States in terms of the selected quality-of-life indicators, which include GDP per capita expressed in purchasing power standards (PPS), average income in euro and severe material deprivation (SMD) expressed as a percentage. Three research methods were used to conduct the research: analysis and criticism of the literature on the national and international scale, analysis of secondary data obtained from the Eurostat database, as well as a statistical method using descriptive statistics, including the use of the dynamics index to estimate the level and direction of changes in the analyzed quality of life measures.
As a result of the conducted research and with the use of the method of aggregating countries in terms of economic indicators describing the quality of life, it was found that rich countries characterized by high socio-economic development featured the highest level of quality of life. They include mainly Luxembourg, and due to the high level of average income and, at the same time, low SMD, Ireland, Austria, and Denmark. The lowest quality of life, but with the highest dynamics of average income, was characteristic of countries such as Bulgaria, Romania, Greece, and Hungary, where GDP was at a low or very low level. It should be added that in these countries, at the same time, some of the lower rates of deprivation dynamics were identified, which was a positive phenomenon. Poland had the lowest SMD dynamics.

Inwestowanie jest nieodłącznym elementem decyzji budżetowych podmiotów prawnych, niezależnie od ich wielkości. Czynniki makroekonomiczne, finansowe i instytucjonalne wpływają na otoczenie działalności inwestycyjnej. W artykule rozważono jeden z elementów makrootoczenia przedsiębiorstw, jakim jest związek między dochodami budżetowymi państwa z tytułu podatku dochodowego od osób prawnych a nakładami inwestycyjnymi małych, średnich i dużych przedsiębiorstw w sektorze prywatnym gospodarki narodowej. Celem badania jest identyfikacja zależności między dochodami budżetowymi państwa z tytułu podatku dochodowego od osób prawnych a wysokością nakładów w sektorze prywatnym gospodarki narodowej wśród przedsiębiorstw zatrudniających powyżej dziewięciu pracowników, w Polsce w latach 2010-2020, na podstawie danych Głównego Urzędu Statystycznego oraz zatwierdzonych przez Radę Ministrów sprawozdań z wykonania budżetu państwa od 2010 do 2020 roku, zawartych na stronie Ministerstwa Finansów. Do weryfikacji postawionej hipotezy badawczej wykorzystano metodę analizy korelacji Pearsona. Na podstawie uzyskanej wartości współczynnika korelacji Pearsona stwierdzono, że między dochodami budżetowymi państwa z tytułu podatku dochodowego od osób prawnych a nakładami inwestycyjnymi w sektorze prywatnym gospodarki narodowej wśród małych, średnich i dużych przedsiębiorstw występuje bardzo silna stochastyczna zależność dodatnia.

Abstract: The social conditions that demarcate space determine, to a large extent, the social and urban experience of those who inhabit it. Inhabiting an urban enclave of poverty configures specific life experiences of youth, and unequal inclusion affects how they live in the city. This article, which derives from research conducted in a poor neighborhood in the city of Tuxtla Gutiérrez, Chiapas (Mexico), presents the implications of the conditions of precariousness and violence that demarcate an urban enclave of poverty by defining specific patterns of socialization that shape the urban and social experiences of the young people who live there.

Economía política y desarrollo en la Zona Bananera (Magdalena, Colombia), 1850–1930
Authors: Franco Reyes Adriano
Published: October 2022

Abstract: This article explores the relationship between a specific political economy and its developmental impacts by analyzing how the Zona Bananera in the north of the Department of Magdalena, Colombia, was configured by the emergence of an agro-exportation model between 1850 and 1930. The review of gubernatorial reports and statistical data highlights how the development deriving from this model concentrated benefits to a small landowning class, which magnified the unequal distribution of land in the area. Therefore, this article documents the negative social consequences deriving from this type of development, particularly in frontier societies like the one in Magdalena at the end of the 19th century and beginning of the 20th century.

Resumen: El artículo explora la relación entre una economía política particular y sus efectos en términos de desarrollo a través del análisis de la configuración de la Zona Bananera en el departamento del Magdalena, Colombia, a partir del surgimiento de una economía política que definió para este un modelo agroexportador en el periodo de 1850 a 1930. La revisión de informes de gobernadores del Magdalena, en conjunto con datos estadísticos resalta cómo el desarrollo derivado de este modelo concentró beneficios en una pequeña clase terrateniente, magnificando la distribución desigual de la tierra. Por lo tanto, este artículo documenta las consecuencias sociales negativas de este tipo de desarrollo, particularmente en sociedades de frontera, como la del Magdalena a finales del XIX principios del XX.

Résumé : Cet article explore les effets d’une économie politique particulière en termes de développement, dans le nord du département du Magdalena, en Colombie, configuré à partir de l’émergence d’un modèle agricole exportateur de 1850 à 1930. L’analyse des rapports rédigés par les gouverneurs du département, ainsi que des données statistiques, montrent comment le modèle concentra des bénéfices en faveur de quelques familles de propriétaires fonciers, et accentua l’inégale répartition des terres. Ainsi, l’article met en évidence les conséquences sociales négatives de ce modèle de développement dans les sociétés de frontière, à la fin du XIXe siècle et au début du XXe siècle.
Radiographic comparison of L5–S1 lateral anterior lumbar interbody fusion cage subsidence and displacement by fixation strategy: anterior plate versus integrated screws
Authors: Theologis Alekos A. , Patel Sohan , Burch Shane
Published: October 2022

OBJECTIVE

The aim of this study was to radiographically compare cage subsidence and displacement between L5–S1 lateral anterior lumbar interbody fusion (ALIF) cages secured with an anterior buttress plate and cages secured with integrated screws.

METHODS

Consecutive patients who underwent L5–S1 lateral ALIF with supplemental posterior fixation by a single surgeon from June 2016 to January 2021 were reviewed. Radiographs were analyzed and compared between the two groups based on the type of fixation used to secure the L5–S1 lateral ALIF cage: 1) anterior buttress plate or 2) integrated screws. The following measurements at L5–S1 were analyzed on radiographs obtained preoperatively, before discharge, and at latest follow-up: 1) anterior disc height, 2) posterior disc height, and 3) segmental lordosis. Cage subsidence and anterior cage displacement were determined radiographically.

RESULTS

One hundred thirty-nine patients (mean age 60.0 ± 14.3 years) were included for analysis. Sixty-eight patients were treated with an anterior buttress plate (mean follow-up 12 ± 5 months), and 71 were treated with integrated screws (mean follow-up 9 ± 3 months). Mean age, sex distribution, preoperative L5–S1 lordosis, preoperative L5–S1 anterior disc height, and preoperative L5–S1 posterior disc height were statistically similar between the two groups. After surgery, the segmental L5–S1 lordosis and L5–S1 anterior disc heights significantly improved for both groups, and each respective measurement was similar between the groups at final follow-up. Posterior disc heights significantly increased after surgery with integrated screws but not with the anterior buttress plate. As such, posterior disc heights were significantly greater at final follow-up for integrated screws. Compared with patients who received integrated screws, significantly more patients who received the anterior buttress plate had cage subsidence cranially through the L5 endplate (20.6% vs 2.8%, p < 0.01), cage subsidence caudally through the S1 endplate (27.9% vs 0%, p < 0.01), and anterior cage displacement (22.1% vs 0%, p < 0.01).

CONCLUSIONS

In this radiographic analysis of 139 patients who underwent lateral L5–S1 ALIF supplemented by posterior fixation, L5–S1 cages secured with an anterior buttress plate demonstrated significantly higher rates of cage subsidence and anterior cage displacement compared with cages secured with integrated screws. While the more durable stability afforded by cages secured with integrated screws suggests that they may be a more viable fixation strategy for L5–S1 lateral ALIFs, there are multiple factors that can contribute to cage subsidence, and, thus, definitive presumption cannot be made that the findings of this study are directly related to the buttress plate.
Alteration of default mode network: association with executive dysfunction in frontal glioma patients
Authors: Zhang Xiaokang , Zhang Guobin , Wang Yonggang , Huang Huawei , Li Haoyi , Li Mingxiao , Yang Chuanwei , Li Ming , Chen Hongyan , Jing Bin , Lin Song
Published: October 2022

OBJECTIVE

Patients with frontal gliomas often experience executive dysfunction (EF-D) before surgery, and the changes in brain plasticity underlying this effect remain obscure. In this study, the authors aimed to assess whole-brain structural and functional alterations by using structural MRI and resting-state functional MRI (rs-fMRI) in frontal glioma patients with or without EF-D.

METHODS

Fifty-seven patients with frontal gliomas were admitted prospectively to the authors’ institution and assigned to one of two groups: 1) the normal executive function (EF-N) group and 2) the EF-D group, based on patient results for the Trail Making Test, Part B and Stroop Color-Word Test, Part C. Twenty-nine baseline-matched healthy controls were also recruited. All participants underwent multimodal MRI examination. Cortical surface thickness, surface-based resting-state activity (fractional amplitude of low-frequency fluctuation [fALFF] and regional homogeneity [ReHo]), and edge-based network functional connectivity (FC) were measured with FreeSurfer and fMRIPrep. The correlation between altered MRI parameters and executive function (EF) was assessed using Pearson correlation and receiver operating characteristic (ROC) analysis.

RESULTS

Demographic characteristics (sex, age, and education level) and clinical characteristics (location, volume, grade of tumor, and preoperative epilepsy) were not significantly different between the groups, but the Karnofsky Performance Scale score was worse in the EF-D group. There was no significant difference in cortical surface thickness between the EF-D and EF-N groups. In both low-grade and high-grade glioma patients the fALFF value (permutation test + threshold-free cluster enhancement, p value after family-wise error correction < 0.05) and ReHo value (t-test, p < 0.001) of the left precuneus cortex in the EF-D group were greater than those in the EF-N group, which were negatively correlated with EF (p < 0.05) and enabled prediction of EF (area under the ROC curve 0.826 for fALFF and 0.855 for ReHo, p < 0.001). Compared with the EF-N group, the FCs between the default mode network (DMN) from DMN node to DMN node (DMN-DMN) and from the DMN to the central executive network (DMN-CEN) in the EF-D group were increased significantly (network-based statistics corrected p < 0.05) and negatively correlated with EF (Pearson correlation, p < 0.05).

CONCLUSIONS

Apart from local disruption, the abnormally activated DMN in the resting state is related to EF-D in frontal glioma patients. DMN activity should be considered during preoperative planning and postoperative neurorehabilitation for frontal glioma patients to preserve EF.

Surgical instruments and catheter damage during ventriculoperitoneal shunt assembly
Authors: Fisher Wilson A. M. , Catalino Michael P. , Woolard E. Alice , Andrews Bethany J. , Elton Scott , Quinsey Carolyn
Published: October 2022

OBJECTIVE

Current surgical techniques use common surgical instruments for sterile shunt assembly. This study investigated the impact of using these techniques and surgical instruments on the mechanical integrity of the ventriculoperitoneal shunt system, specifically shunt catheters.

METHODS

The authors conducted failure testing on 85 rifampin-coated catheters and 85 barium-impregnated catheters using 5 different surgical instruments and 2 different surgical techniques. In technique A, the distal end of the catheter was pushed onto the shunt valve inlet connector with the surgical instrument. In technique B, the catheter was pulled over the inlet connector. One hundred sixty catheters underwent 10-repetition-maximum testing, in which the catheter either failed before completion of 10 consecutive assembly/disassembly repetitions or the catheter completed 10 consecutive repetitions. The authors also conducted 100-repetition-maximum tests on 5 barium-impregnated and 5 rifampin-coated catheters using technique A.

RESULTS

Catheter failure rates were significantly different among the different instruments used in assembly (p ≤ 0.001). Post hoc analysis showed that using mosquito forceps with shods resulted in a significantly lower catheter failure rate than the other instruments (p < 0.0005). The catheter failure rate of technique A was significantly lower than that of technique B (5% vs 81%, p < 0.001). There was no statistical difference between the failure rates of the barium and rifampin catheters (42% vs 44%, p = 0.9), but the barium catheters outperformed the rifampin catheters in the 100-repetition-maximum trials (p = 0.02). Instrument type (p = 0.0232) and catheter type (p = 0.0096) were both significant factors in determining the number of assembly/disassembly repetitions needed to cause catheter failure. It took an average of 2.79 repetitions of assembly/disassembly to cause catheter failure. DeBakey forceps had significantly lower mean repetitions to failure (mean 1.38) than the Gerald forceps without teeth (mean 2.73, p = 0.05) and bayonet (mean 3.25, p = 0.02).

CONCLUSIONS

This study was the first of its kind to analyze how physical manipulation affects the mechanical integrity of ventriculoperitoneal shunt components. The authors demonstrated a significantly lower shunt catheter failure rate when mosquito forceps with shods and technique A were used in assembly. Moreover, the authors established that use of DeBakey forceps resulted in failure with fewer assembly/disassembly repetitions than use of the Gerald and bayonet forceps, suggesting that DeBakey forceps are the most damaging instrument.

Published: October 2022

OBJECTIVE

Since 2007, the authors have performed 34 hemispherotomies and 17 posterior quadrant disconnections (temporoparietooccipital [TPO] disconnections) for refractory epilepsy at Sant Joan de Déu Barcelona Children’s Hospital. Incomplete disconnection is the main cause of surgical failure in disconnective surgery, and reoperation is the treatment of choice. In this study, 6 patients previously treated with hemispherotomy required reoperation through open surgery. After the authors’ initial experience with real-time MRI-guided laser interstitial thermal therapy (MRIgLITT) for hypothalamic hamartomas, they decided to use this technique instead of open surgery to complete disconnective surgeries. The objective was to report the feasibility, safety, and efficacy of MRIgLITT to complete hemispherotomies and TPO disconnections for refractory epilepsy in pediatric patients.

METHODS

Eight procedures were performed on 6 patients with drug-resistant epilepsy. Patient ages ranged between 4 and 18 years (mean 10 ± 4.4 years). The patients had previously undergone hemispherotomy (4 patients) and TPO disconnection (2 patients) at the hospital. The Visualase system assisted by a Neuromate robotic arm was used. The ablation trajectory was planned along the residual connection. The demographic and epilepsy characteristics of the patients, precision of the robot, details of the laser ablation, complications, and results were prospectively collected.

RESULTS

Four patients underwent hemispherotomy and 2 underwent TPO disconnection. Two patients, including 1 who underwent hemispherotomy and 1 who underwent TPO disconnection, received a second laser ablation because of persistent seizures and connections after the first treatment. The average precision of the system (target point localization error) was 1.7 ± 1.4 mm. The average power used was 6.58 ± 1.53 J. No complications were noted. Currently, 5 of the 6 patients are seizure free (Engel class I) after a mean follow-up of 20.2 ± 5.6 months.

CONCLUSIONS

According to this preliminary experience, laser ablation is a safe method for complete disconnective surgeries and allowed epilepsy control in 5 of the 6 patients treated. A larger sample size and longer follow-up periods are necessary to better assess the efficacy of MRIgLITT to complete hemispherotomy and TPO disconnection, but the initial results are encouraging.

Sowohl in Deutschland als auch in ganz Europa ist seit einigen Jahren ein wachsender Trend zu autoritären, demokratie- und menschenfeindlichen Denk- und Handlungsweisen zu verzeichnen. Trotz einer angenommenen hohen Sensibilität gegenüber solchen Positionen ist eine Einflussnahme auch auf die Soziale Arbeit und ihre Akteure nicht ausgeschlossen. Die Studie „Die extreme Rechte in der Sozialen Arbeit in MV“ (Laufzeit 06/2020–07/2021) untersucht die Versuche der Einflussnahme extrem rechter Diskurse und Akteure auf die bzw. innerhalb der Sozialen Arbeit in Mecklenburg-Vorpommern systematisch mithilfe eines Mixed-Methods-Ansatzes. Der Artikel stellt die Ergebnisse der Studie sowie ihre methodische Umsetzung dar und analysiert die empirischen Zugänge und methodischen Möglichkeiten der Wissenschaft Sozialer Arbeit in Hinblick auf eigene Beiträge zur Rechtsextremismusforschung.
„…dass sie mich als […] armen kleinen Penner darstellt, der ihr sowieso nicht gewachsen sei“. Eine psychoanalytisch-sozialpsychologische Perspektive auf männliche Hegemonie und Antifeminismus auf Basis einer tiefenhermeneutischen Fallrekonstruktion
Authors: Berg Philipp
Published: October 2022

Auf Basis einer tiefenhermeneutischen Fallrekonstruktion wird der Frage nachgegangen, warum sich auch gut ausgebildete Männer in geregelten Beschäftigungsverhältnissen mit einem überdurchschnittlichen Einkommen in ihrer männlichen Hegemonie bedroht sehen und antifeministisch reagieren können. Es wird gezeigt, dass sie versuchen, Versagensängste, Selbstbeschämungen und -entwertungen als Mann abzuwehren, welche von den antifeministischen Narrativen der extremen Rechten noch potenziert werden. Dabei werden Ergänzungen zwischen dem machttheoretischen Ansatz hegemonialer Männlichkeit und der psychoanalytischen Sozialpsychologie aufgezeigt.
A Polyhedral Abstraction for Petri Nets and its Application to SMT-Based Model Checking
Authors: Amat Nicolas , Berthomieu Bernard , Dal Zilio Silvano
Published: October 2022

We define a new method for taking advantage of net reductions in combination with a SMT-based model checker. Our approach consists in transforming a reachability problem about some Petri net, into the verification of an updated reachability property on a reduced version of this net. This method relies on a new state space abstraction based on systems of constraints, called polyhedral abstraction. We prove the correctness of this method using a new notion of equivalence between nets. We provide a complete framework to define and check the correctness of equivalence judgements; prove that this relation is a congruence; and give examples of basic equivalence relations that derive from structural reductions. Our approach has been implemented in a tool, named SMPT, that provides two main procedures: Bounded Model Checking (BMC) and Property Directed Reachability (PDR). Each procedure has been adapted in order to use reductions and to work with arbitrary Petri nets. We tested SMPT on a large collection of queries used in the Model Checking Contest. Our experimental results show that our approach works well, even when we only have a moderate amount of reductions.
Synthesis of Pure and Impure Petri Nets with Restricted Place-environments: Complexity Issues
Authors: Devillers Raymond , Tredup Ronny
Published: October 2022

Petri net synthesis consists in deciding for a given transition system A whether there exists a Petri net N whose reachability graph is isomorphic to A. Several works examined the synthesis of Petri net subclasses that restrict, for every place p of the net, the cardinality of its preset or of its postset or both in advance by small natural numbers ϱ and κ, respectively, such as for example (weighted) marked graphs, (weighted) T-systems and choice-free nets. In this paper, we study the synthesis aiming at Petri nets which have such restricted place environments, from the viewpoint of classical and parameterized complexity: We first show that, for any fixed natural numbers ϱ and κ, deciding whether for a given transition system A there is a Petri net N such that (1) its reachability graph is isomorphic to A and (2) for every place p of N the preset of p has at most ϱ and the postset of p has at most κ elements is doable in polynomial time. Secondly, we introduce a modified version of the problem, namely ENVIRONMENT RESTRICTED SYNTHESIS (ERS, for short), where ϱ and κ are part of the input, and show that ERS is NPcomplete, regardless whether the sought net is impure or pure. In case of the impure nets, our methods also imply that ERS parameterized by ϱ + κ is W[2]-hard.
Computing Parameterized Invariants of Parameterized Petri Nets
Authors: Esparza Javier , Raskin Mikhail , Welzel Christoph
Published: October 2022

A fundamental advantage of Petri net models is the possibility to automatically compute useful system invariants from the syntax of the net. Classical techniques used for this are place invariants, P-components, siphons or traps. Recently, Bozga et al. have presented a novel technique for the parameterized verification of safety properties of systems with a ring or array architecture. They show that the statement “for every instance of the parameterized Petri net, all markings satisfying the linear invariants associated to all the P-components, siphons and traps of the instance are safe” can be encoded in WS1S and checked using tools like MONA. However, while the technique certifies that this infinite set of linear invariants extracted from P-components, siphons or traps are strong enough to prove safety, it does not return an explanation of this fact understandable by humans. We present a CEGAR loop that constructs a finite set of parameterized P-components, siphons or traps, whose infinitely many instances are strong enough to prove safety. For this we design parameterization procedures for different architectures.

Method for education value evaluation with regional culture integration into international students’ ideological education under fuzzy number intuitionistic fuzzy environment
Authors: Xia Fangfang
Published: October 2022

For thousands of years, the Chinese people have accumulated and inherited profound cultural traditions. The uniqueness of this cultural tradition lies in its amazing creative wisdom and power. “The ideological and political education of the integration of Chinese regional culture into international students refers to the educative influence of excellent regional culture that can run through the entire international education management system, curriculum system and extracurricular practice system to achieve “all-round, full-process, full-staff” Education goals. The sustainable education value evaluation based on the integration of regional culture into international students’ ideological education is a classical multiple-attribute decision-making (MADM) issue. In this paper, we extend the geometric Heronian mean (GHM) operator to fuzzy number intuitionistic fuzzy numbers (FNIFNs) to propose the fuzzy number intuitionistic fuzzy GHM (FNIFGHM) operator. Then, the multiple-attribute decision-making (MADM) methods are built on FNIFGHM operator. Finally, a numerical example for sustainable education value evaluation based on the integration of regional culture into international students’ ideological education and some comparative analysis are used to prove the built methods’ credibility and reliability.

Published: October 2022

This study analyzes the expected effects of climate change on Colombia’s current account. To this end, we present a literature review that outlines how climate-related risks could impact the balance of payments, complemented with an analysis that illustrates how the 2014-2015 oil shock affected the country's external sector. Subsequently, we show a projection of the current account balance through 2050 under different climate scenarios in order to establish whether the incidence of these risks would affect the country’s long-run current account. Our results indicate that achieving net-zero emissions by 2050 could widen the current account deficit, relative to a continuation of current climate policies, by an amount ranging between 2.6% and 4.6% of GDP.
