Bi-Unitary Superperfect Polynomials over 𝔽2 with at Most Two Irreducible Factors
Authors: Chehade Haissam , Miari Domoo , Alkhezi Yousuf
Published: November 2023

A divisor B of a nonzero polynomial A, defined over the prime field of two elements, is unitary (resp. bi-unitary) if gcd(B,A/B)=1 (resp. gcdu(B,A/B)=1), where gcdu(B,A/B) denotes the greatest common unitary divisor of B and A/B. We denote by σ**(A) the sum of all bi-unitary monic divisors of A. A polynomial A is called a bi-unitary superperfect polynomial over F2 if the sum of all bi-unitary monic divisors of σ**(A) equals A. In this paper, we give all bi-unitary superperfect polynomials divisible by one or two irreducible polynomials over F2. We prove the nonexistence of odd bi-unitary superperfect polynomials over F2.
Exponential Stability for Second-Order Neutral Stochastic Systems Involving Impulses and State-Dependent Delay
Authors: Ganesan Arthi , Thangaraj Manju , Ma Yong-Ki
Published: November 2023

Exponential stability criteria for neutral second-order stochastic systems involving impulses and state-dependent delay have been addressed in this paper based on stability theory, stochastic analysis, and the inequality technique. Some sufficient conditions are given to establish the exponential stability of such systems, which is well-established in the deterministic case, but less known for the stochastic case. In our model, the noise effect can be described as a symmetric Wiener process. By formulating the impulsive integral technique, exponential stability analysis of the pth moment of the second-order system involving stochastic perturbation is established. As an application that illustrates the theoretical formulation, an example is presented.

Published: November 2023

Forage grain contamination with aflatoxin B1 (AFB1) is a global problem, so its detoxification with the aim of providing feed safety and cost-efficiency is still a relevant issue. AFB1 degradation by microbial enzymes is considered to be a promising detoxification approach. In this study, we modified an previously developed Pichia pastoris GS115 expression system using a chimeric signal peptide to obtain a new recombinant producer of extracellular AFB1 oxidase (AFO) from Armillaria tabescens (the yield of 0.3 g/L), purified AFO, and selected optimal conditions for AFO-induced AFB1 removal from model solutions. After a 72 h exposure of the AFB1 solution to AFO at pH 6.0 and 30 °C, 80% of the AFB1 was degraded. Treatments with AFO also significantly reduced the AFB1 content in wheat and corn grain inoculated with Aspergillus flavus. In grain samples contaminated with several dozen micrograms of AFB1 per kg, a 48 h exposure to AFO resulted in at least double the reduction in grain contamination compared to the control, while the same treatment of more significantly (~mg/kg) AFB1-polluted samples reduced their contamination by ~40%. These findings prove the potential of the tested AFO for cereal grain decontamination and suggest that additional studies to stabilize AFO and improve its AFB1-degrading efficacy are required.

Mudanjiang phlebovirus (MJPV) is a newly discovered phlebovirus, initially detected from Ixodes persulcatus ticks in China in 2022. In this study, by next-generation sequencing (NGS) on a wide variety of ticks and wild small animals in China, we detected MJPV from I. persulcatus and Meriones meridianus. Additionally, we conducted RT-PCR and sequencing on 1815 adult ticks and 805 wild small mammals collected from eight provinces in China between 2017 and 2021. MJPV RNA-positive results were found in 0.22% (4/1815) of tick samples, as well as in 0.12% (1/805) of rodent samples. All positive detections were obtained from Heilongjiang and Inner Mongolia. Sequencing analysis revealed nucleotide similarities ranging from 98.23% to 99.11%, as well as amino acid similarities ranging from 99.12% to100%, between the current MJPV strain and previously reported strains of MJPV. Phylogenetic tree analysis demonstrated that the previously reported MJPV strain along with our two variants clustered together with other tick-borne phenuiviruses, indicating their close relationship within this viral group. This study represents the first detection of MJPV infection in wild rodents, expanding the known host range for this virus in the endemic regions.

Published: November 2023

Tick-borne encephalitis virus (TBEV) is the most important tick-transmitted neurotropic flavivirus in Europe and Asia. Our analysis aimed to investigate the contribution of TBEV-specific antibody detection by serological assays and TBEV RNA detection by real-time PCR to the diagnosis of tick-borne encephalitis (TBE). We analyzed data from 3713 patients from 16 years of laboratory TBEV diagnostics in an endemic area in Southern Germany. During this period, 126 cases of TBE were diagnosed. TBEV-specific IgM ELISA tests showed a high clinical sensitivity (96.8%) and a very high clinical specificity (99.7%). In immunocompetent patients, TBE was reliably diagnosed by detection of TBEV IgM antibodies in serum. Intrathecal TBEV IgG antibody synthesis was detected in 46 of 84 (55%) cases by analysis of paired serum and cerebrospinal fluid (CSF) samples. None of the 87 immunocompetent TBE patients tested had detectable TBEV RNA in serum or CSF. In contrast, in two TBE patients without TBEV-specific antibodies, diagnosis could only be made by the detection of TBEV RNA in CSF. Both patients had previously been treated with the B cell-depleting antibody rituximab. Therefore, in patients with CNS infection and humoral immunodeficiency, it is necessary to include TBEV PCR in the diagnostic approach.

Published: November 2023

Pedilanthus leaf curl virus (PeLCV) is a monopartite begomovirus (family Geminiviridae) discovered just a few decades ago. Since then, it has become a widely encountered virus, with reports from ca. 25 plant species across Pakistan and India, indicative of its notable evolutionary success. Viruses mutate at such a swift rate that their ecological and evolutionary behaviors are inextricably linked, and all of these behaviors are imprinted on their genomes as genetic diversity. So, all these imprints can be mapped by computational methods. This study was designed to map the sequence variation dynamics, genetic heterogeneity, regional diversity, phylogeny, and recombination events imprinted on the PeLCV genome. Phylogenetic and network analysis grouped the full-length genome sequences of 52 PeLCV isolates into 7 major clades, displaying some regional delineation but lacking host-specific demarcation. The progenitor of PeLCV was found to have originated in Multan, Pakistan, in 1977, from where it spread concurrently to India and various regions of Pakistan. A high proportion of recombination events, distributed unevenly throughout the genome and involving both inter- and intraspecies recombinants, were inferred. The findings of this study highlight that the PeLCV population is expanding under a high degree of genetic diversity (π = 0.073%), a high rate of mean nucleotide substitution (1.54 × 10−3), demographic selection, and a high rate of recombination. This sets PeLCV apart as a distinctive begomovirus among other begomoviruses. These factors could further exacerbate the PeLCV divergence and adaptation to new hosts. The insights of this study that pinpoint the emergence of PeLCV are outlined.
Identification of an Ortholog of MALT1 from Shrimp That Induces NF-κB-Mediated Antiviral Immunity
Authors: Wang Haiyang , Xiao Bang , Chen Shihan , He Jianguo , Li Chaozheng
Published: November 2023

MALT1 (mucosa-associated lymphoid tissue lymphoma translocation protein 1) serves as a pivotal mediator for NF-κB activation in response to a wide spectrum of transmembrane receptor stimuli. In the present study, a homolog of MALT1, named LvMALT1, is cloned from the Pacific white shrimp (Litopenaeus vannamei) and its potential function in shrimp innate immunity is explored. The open reading frame of LvMALT1 is 2364 bp that encodes 787 amino acids. The predicted LvMALT1 protein structure comprises a death domain, three immunoglobulin domains, and a caspase-like domain, exhibiting remarkable similarity to other homologs. LvMALT1 is a cytoplasmic-localized protein and could interact with LvTRAF6. Overexpression of LvMALT1 induces the activation of promoter elements governing the expression of several key antimicrobial peptides (AMPs), including penaeidins (PENs) and crustins (CRUs). Conversely, silencing of LvMALT1 leads to a reduction in the phosphorylation levels of Dorsal and Relish, along with a concomitant decline in the in vivo expression levels of multiple AMPs. Furthermore, LvMALT1 is prominently upregulated in response to a challenge by the white spot syndrome virus (WSSV), facilitating the NF-κB-mediated expression of AMPs as a defense against viral infection. Taken together, we identified a MALT1 homolog from the shrimp L. vannamei, which plays a positive role in the TRAF6/NF-κB/AMPs axis-mediated innate immunity.

Published: November 2023

Soybean mosaic virus (SMV), a member of Potyvirus, is the most destructive and widespread viral disease in soybean production. Our earlier studies identified a soybean 40S ribosomal protein S8 (GmRPS8) using the 6K1 protein of SMV as the bait to screen a soybean cDNA library. The present study aims to identify the interactions between GmRPS8 and SMV and characterize the role of GmRPS8 in SMV infection in soybean. Expression analysis showed higher SMV-induced GmRPS8 expression levels in a susceptible soybean cultivar when compared with a resistant cultivar, suggesting that GmRPS8 was involved in the response to SMV in soybean. Subcellular localization showed that GmRPS8 was localized in the nucleus. Moreover, the yeast two-hybrid (Y2H) experiments showed that GmRPS8 only interacted with 6K1 among the eleven proteins encoded by SMV. The interaction between GmRPS8 and 6K1 was further verified by a bimolecular fluorescence complementation (BiFC) assay, and the interaction was localized in the nucleus. Furthermore, knockdown of GmRPS8 by a virus-induced gene silencing (VIGS) system retarded the growth and development of soybeans and inhibited the accumulation of SMV in soybeans. Together, these results showed that GmRPS8 interacts with 6K1 and contributes to soybean susceptibility to SMV. Our findings provide new insights for understanding the role of GmRPS8 in the SMV infection cycle, which could help reveal potyviral replication mechanisms.

Oropharyngeal dysphagia (OD) is a swallowing disorder that involves difficulty in safely passing the food bolus from the oral cavity to the stomach. OD is a common problem in children with congenital Zika virus syndrome (CZS). In this case series, we describe the clinical and acoustic alterations of swallowing in children exposed to the Zika virus during pregnancy in a cohort from Amazonas, Brazil. From July 2019 to January 2020, 22 children were evaluated, 6 with microcephaly and 16 without microcephaly. The mean age among the participants was 35 months (±4.6 months). All children with microcephaly had alterations in oral motricity, mainly in the lips and cheeks. Other alterations were in vocal quality, hard palate, and soft palate. Half of the children with microcephaly showed changes in cervical auscultation during breast milk swallowing. In children without microcephaly, the most frequently observed alteration was in lip motricity, but alterations in auscultation during the swallowing of breast milk were not observed. Regarding swallowing food of a liquid and pasty consistency, the most frequent alterations were incomplete verbal closure, increased oral transit time, inadequacy in capturing the spoon, anterior labial leakage, and increased oral transit time. Although these events are more frequent in microcephalic children, they can also be seen in non-microcephalic children, which points to the need for an indistinct evaluation of children exposed in utero to ZIKV.

In 2009, a novel H1N1 influenza virus caused the first influenza pandemic of the 21st century. Studies have shown that the influenza M gene played important roles in the pathogenicity and transmissibility of the 2009 H1N1 pandemic ((H1N1)pdm09), whilst the underlying mechanism remains unclear. The influenza M gene encodes two proteins, matrix protein 1 and matrix protein 2, which play important roles in viral replication and assembly. In this study, it is found that the M2 protein of the (H1N1)pdm09 virus showed a lower mobility rate than the North America triple-reassortant influenza M2 protein in Polyacrylamide Gel Electrophoresis (PAGE). The site-directed mutations of the amino acids of (H1N1)pdm09 M2 revealed that E79 is responsible for the mobility rate change. Further animal studies showed that the (H1N1)pdm09 containing a single M2-E79K was significantly attenuated compared with the wild-type virus in mice and induced lower proinflammatory cytokines and IFNs in mouse lungs. Further in vitro studies indicated that this mutation also affected NLRP3 inflammasome activation. To reveal the reason why they have different mobility rates, a circular dichroism spectra assay was employed and showed that the two M2 proteins displayed different secondary structures. Overall, our findings suggest that M2 E79 is important for the virus replication and pathogenicity of (H1N1)pdm09 through NLRP3 inflammasome and proinflammatory response.

Rift Valley fever virus (RVFV) is a mosquito-borne zoonotic pathogen causing disease in livestock and humans. Whilst initially restricted to the African continent, recent spread to the Arabian Peninsula has highlighted the likelihood of entry into new regions. Due to the absence of a regulatory-approved human vaccine, work is ongoing to develop and assess countermeasures. As such, small animal models play a pivotal role in providing information on disease pathogenesis and elucidating which intervention strategies confer protection. To develop and establish the BALB/c mouse model, we challenged mice with RVFV grown from two separate cell lines: one derived from mosquitoes (C6/36) and the other mammalian derived (Vero E6). Following infection, we assessed the clinical course of disease progression at days 1 and 3 post-challenge and evaluated viral tropism and immune analytes. The results demonstrated that RVFV infection was affected by the cell line used to propagate the challenge virus, with those grown in insect cells resulting in a more rapid disease progression. The lowest dose that caused uniform severe disease remained the same across both virus preparations. In addition, to demonstrate reproducibility, the lowest dose was used for a subsequent infection study using male and female animals. The results further demonstrated that male mice succumbed to infection more rapidly than their female counterparts. Our results establish an RVFV mouse model and key parameters that affect the course of disease progression in BALB/c mice.
Location and Extents of Scour Hole around an Erodible Spill-through Abutment under Clear Water Condition and the Abutment Classification
Authors: Abid Irfan , Sturm Terry W. , Hong Seung Ho
Published: November 2023

Bridge abutment scour is a complex phenomenon, which significantly affects bridge stability and is responsible for the damage and failures of many bridges over waterways across the world. Given the widespread and devastating human and societal costs, numerous experimental studies have been conducted to find the mechanisms of bridge abutment scour, and several empirical and mathematical prediction models are available. However, the location of the scour hole and its extents have not been investigated in detail, which is one of the important parameters, not only for the bridge stability itself, but also for the safety of structures around the bridge and their design. Thus, in this study, laboratory experiments were carried out using several different lengths of erodible abutment under different flow conditions to suggest a new mathematical criterion for abutment classification with respect to the location of scour holes. Furthermore, additional analysis was conducted to locate the point of the deepest scour depth and extent of the scour hole around the abutment. Both in transverse and flow direction, the location of the scour hole and the point of the deepest scour are governed by the geometric contraction ratio. This research will be useful in analyzing the bridge safety itself as well as safety of the river training works close to the bridge with respect to the location and extents of the scour hole.

Published: November 2023

This article analyzes the problems of the deposit market development related to the limited resource base of banks for long-term lending and investment in Russia. The conjunctural overview of the bank deposit market and ideas for its development are presented. The necessity of solving the problem of "long" money for the development of the real sector of the economy through the general growth of bank deposits of individuals and an increase in the share and duration of term deposits is substantiated. A solution is proposed to increase longterm resources by placing funds of individual pension savings in the banking system using a floating interest rate.
Challenged? Supporting Nursing Students with Dyslexia in Clinical Placements
Authors: Malbon Isobel J.
Published: November 2023

From my own experience as a Student Nurse Educator and my role as an Academic Liaison Nurse (ALN) in a Dedicated Education Unit (DEU), clinical practicums can be challenging for our nursing students. Responses in practicum can vary from exciting to downright scary, but for those with additional challenges such as dyslexia, getting words mixed up or incorrect spelling can have a devastating effect on their confidence and their ability to fulfil their role. This paper draws on a study completed for my Master of Applied Professional Practice about the stigma of dyslexia and the impact on nursing students. Using a framework of qualitative phenomenology, I conducted face-to-face interviews with five participants, and then employed narrative analysis to better understand their journeys. I was privileged to hear their personal stories as current nursing students and graduates talked about how they managed barriers, including fatigue, and expectations while completing their practicums. This paper shares some of the coping strategies participants offered, as well as my own reflections of how teaching and clinical staff can help. Educators and clinical leads alike need to be knowledgeable and skilled, and understanding of those with different learning styles and preferences. Consistent support and, often, repetition, are the keys to learning, and reducing stress and fatigue for those with dyslexia. In our sector, multiple programmes have work experience, placements or internships, and many of the issues and responses discussed will be transferable beyond the Bachelor of Nursing degree. I hope that sharing some of the participants’ stories and my own observations may encourage others to consider how they support learners with dyslexia and discover new ideas that work.
Mental Health and Hauora in Education and Policy: An Opening Discourse
Authors: James Fatma
Published: November 2023

The current national school curriculum addresses hauora in the Health and Physical Education Curriculum; however, a review and analysis of the literature shows a lack of sustainable initiatives to support students who have experienced extreme emotional trauma, especially during the global pandemic. This article presents a critique of He Ara Oranga as the primary government inquiry document into mental health and shares the challenges that students face around mental health within the educational context. The effects of grief and loss are covered broadly in mental health and hauora, and discussed within the education context. The article highlights the inequity in the Mental Health Act to help the implementation and practice of support systems such as counselling at grassroots level, specifically in the education context. The effects of policy transcend schools and tertiary institutions; therefore, the author urges educators and scholars alike to persistently adapt and endeavour to reframe the complexities of mental health and hauora in educational settings. The article is an open discourse that argues that policies should strongly embrace future research to maintain systematic and sustainable approaches to support localised solutions.
“The Eggshell of People”: Listening to Children’s Descriptions of Dyslexia
Authors: Beckwith Victoria
Published: November 2023

Children are often underserved because of their age, academic level, and accessibility to the processes in place to develop resources, research and policies. Being neurodivergent, or living in a neurodivergent home, can augment childhood challenges. Listening to dyslexic people, including children, offers an opportunity to respectfully visit unique dyslexic lived experiences, to explore these rich contributions, and to gain fresh insights into people’s journeys. I am a dyslexic parent of a dyslexic child, and an advocate for the wider dyslexic community. I have personally found it can be challenging to articulate how dyslexia is experienced, irrespective of age, because of the difficulties dyslexic people have with expressing themselves (Lithari, 2021). This essay describes how one ten-year-old child chose to highlight dyslexia in their own words, by creating an A4 poster. Starting by looking at what is being created in thedyslexic space in Aotearoa New Zealand, the essay then discusses dyslexic lived experiences. The essay continues with a reflection on the importance of children’s ideas – for example in planning projects and neighbourhood destinations – followed by comments on how the “eggshell of people” analogy might be used by educators to open up discussions about dyslexia and encourage inclusive, and safe, learning environments. It concludes with discussion points for further thought.
Early Reflections on a Collaborative Research Project About the Safety of Rainbow Ākonga on Te Pūkenga Campuses

Published: November 2023

This paper reports on the experiences of a research team designing and beginning to implement a research project exploring how safe and inclusive the various campuses of Te Pūkenga are for Rainbow ākonga (students). As Aotearoa New Zealand’s largest tertiary education provider, Te Pūkenga is bound and shaped by current anti-discrimination social policies. Under the 1993 Human Rights Act, discrimination based on gender was banned in Aotearoa. Same-sex marriage was legalised in 2013, and since 2021 people have been able to change their birth sex on official documents. In 2021, the Government also banned conversion therapy. However, despite these policies and as numerous national studies have documented, educational institutions remain hostile spaces for Rainbow ākonga. We aim to investigate ākonga and kaimahi (staff) experiences of inclusivity and discrimination across Te Pūkenga campuses. A research design was established, and we are in the process of collecting data. Because we have just begun the fieldwork at the time of this writing, we cannot discuss our findings to date. Instead, this article uses the feminist method of storytelling to explore the formation of a collaborative multi-site research team, the necessity of consulting with a Rainbow youth organisation when designing the survey, the research team’s duty of care to participants, the ethics process involved in conducting a multi-site organisational study and managing ‘teething problems’ when the online survey went live. This paper thus reports on our experiences of overcoming hurdles associated with a multi-site research project at a time of transition into one organisation, Te Pūkenga.

Published: November 2023

Os processos exotérmicos requerem um gerenciamento de segurança confiável e organizado em virtude das consequências que o aumento do calor do meio reacional pode gerar, como uma possível perda de contenção, ruptura do vaso ou reator e liberação de gases tóxicos devido à ebulição violenta dos reagentes. Por isso, o sistema de controle e monitoração de processos é de extrema importância na indústria química sendo que diversas ferramentas de análise estão disponíveis e auxiliam no controle e prevenção de falhas. O trabalho teve como finalidade analisar as causas e a probabilidade de ocorrência do superaquecimento de um reator operando em uma planta de nitração assim como suas consequências por meio dos métodos de Árvores de Falhas e Árvore de Eventos. Na árvore de falhas foram realizados os cálculos de probabilidade de ocorrência dos eventos básicos e intermediários que levam ao superaquecimento do reator, a confiabilidade dos equipamentos assim como a taxa de falha deste evento de topo (0,0711 falhas/ano). Além disso, verificou-se que o tempo médio de falha do superaquecimento do reator será de 14,07 anos. Com a Árvore de Eventos foi possível averiguar as probabilidades de sucesso e falha dos eventos que sucedem o superaquecimento do reator até sua explosão. Dentre as consequências resultantes da falha do superaquecimento do reator pode-se destacar a perda de rendimento e pureza dos produtos e possíveis acidentes na planta. Portanto, ao analisar todas as falhas e suas probabilidades pode-se afirmar que o valor de tempo médio encontrado é um número alto visto que uma falha desta dimensão acarretará uma possível destruição da planta gerando um prejuízo imensurável para os acionistas bem como para à comunidade em torno da planta industrial.

Mungbean (Vigna radiata L.) is a type of legume plant with high protein and a short life of approximately 2 months. This plant is found in all regions of Indonesia. The morphology of the mungbean plant consists of roots, stems, leaves, flowers, fruits, and seeds. Mungbean seeds have nutritional content but are in an inactive (dormant) form, after being germinated, the nutrient content is activated, thereby increasing digestibility for humans. A germination is a biological event that occurs from a seed in a dormant state until it becomes a growing seed. Sprouts derived from green bean seeds are called bean sprouts. The germination process can increase the nutritional value of mungbeans, thus, in this journal, a study was conducted to determine the growth model of mungbean sprouts in order to determine the best time to consume bean sprouts. In modeling the growth of green bean sprouts, a predator and prey model is used, which is resolved numerically using the fourth order Runge-Kutta method. From the research conducted, it can be concluded that the maximum nutrition of bean sprouts is on the third day since germination begins.

Premi or known as Contributions in sharia insurance are part of tabbaru fund which is paid by participants. Tabarru’ has puposes to provide the "benevolent funds" with the sincere intention of helping each other among fellow "takaful" participants when one of them suffers a misfortune, such as death. These funds provided by insurance participants will be used to pay claims or insurance benefits by insurance companies. A sharia insurance company is considered doing well financially when tabbaru's funds are well managed to paid the insurance claim. In addition, the company must have sufficient funds to overcome the underwriting deficit in case it happen. This study aims to simulate the adequacy of a company's tabarru’ funds in each period, assuming there is no change in the number of participants during that period. The simulation results can conclude the adequacy of tabarru funds to pay participant claims. Sum of tabarru’ funds are calculated based on the sum of each participant's tabarru’ contribution, which is affected by each sharia-linked unit life insurance product and the participant's policy period. The tabarru’ fund sufficiency simulation is predicted using the IMA(2,1) time series model. The results of this study conclude that the average tabarru funds for each product will be used up in the following year with the criteria of the number of people making claims of not less than five participants. In this study, we found that the company can survive if the number of claims paid from the tabarru' fund with participants tabarru' fund contributions is balanced.

The Consumer Price Index (CPI) is an indicator that influences economic growth. CPI is an index that calculates the average of price change of a group of goods and services consumed by households in a certain period of time. CPI is also used to measure inflation in a country. Inflation is described by changes in the CPI from time to time. To anticipate and minimize economic risks caused by inflation, forecasting will be carried out on CPI data. In this study, the CPI will be predicted for the next 6 months using the ARIMA (Autoregressive Integrated Moving Average) model. The result of this research shows that the ARIMA models that can be used to predict CPI are ARIMA (0,2,0), ARIMA (0,2,1), ARIMA (1,2,0), and ARIMA (1,2,1) . The selection of the best model is carried out based on the model that has the smallest AIC value. Based on this, the best model used to predict CPI is the ARIMA model (0,2,1) with an AIC value of 83.21. In addition, this model fulfills diagnostics with white noise residuals, so that forecasting results using this model will be more accurate.

Geologically, the fossilization of wood materials into fossils requires appropriate conditions, some of which have been preserved for millions of years. In nature, the organic mass of wood must be quickly replaced by inorganic elements before it decomposes under harsh geological conditions. Anorganic oxides such as silica-oxide, are known to be the main components of most wood specimens (up to 80%). The presence of alkaline oxides such as sodium and potassium oxide seems to play a major role in the presence of dissolved silica during petrification. However, their significance in the petrification phenomenon that occurs in fossilized plant wood is not yet known. Therefore, in this study, cluster analysis was conducted to determine the relationship between the presence of silica and alkaline compounds in petrified wood fossils. The approach used was -means clustering supported by the Elbow Method, which aims to review and order a complex set of data into subsets, thus allowing interpretation. The results showed that the clustering of the fossil wood composition data was optimal at  = 3. There is a fair correlation between the presence of silica and alkali oxide compounds (-0.504 to -0.387), as well as with another inorganic compounds (+0.957). The presence of sodium and potassium is strongly correlated during silicification (+0.905). Additionally, the results of data clustering made the wood fossilization process susceptible to describe, especially through data regression. The data visualization provides more facts and proper explanations of the role of alkaline oxides in wood silicification. This study furthers our understanding of wood fossilization, especially the diagenesis of wood chemical composition in geological history.

The relationship between public spending and unemployment is an important topic of study in economics. Public spending was seen as the main cause of rising unemployment, contrary to the idea that it would contribute to the reduction of unemployment. The present paper studies the relationship between the unemployment rate and public spending in a panel of 16 EU states, covering the period 1990–2019 panel and generalized method of moments (GMM) to estimate our dynamic panel data model, which also takes into account the lagged unemployment rate. The model results indicate that public expenditure has a significant positive impact on unemployment. These results confirm the existence of the Abrams curve and the relationship between these two variables is positive.
