Abstract
Using artificial intelligence-based tools, this research aims to establish a direct correlation between the alkali-activated concrete (AAC) mix design factors and their performances. More specifically, the machine learning system was fed new property data obtained from AAC mixes used in laboratory experiments. The rheological parameters (yield stress [static/dynamic] and plastic viscosity) of AAC were predicted using the multilayer perceptron neural network (MLPNN) and bagging ensemble (BE) models. In addition, the R
2 values, k-fold analyses, statistical checks, and the dissimilarity between the experimental and predicted compressive strength were employed to assess the performance of the created models. Also, the SHapley additive exPlanation (SHAP) approach was used for examining the relevance of influencing parameters. The BE approach was found to be significantly accurate in all prediction models, with R
2 greater than 0.90, and MLPNN models were found to be moderately precise, with R
2 slightly below 0.90. However, the error assessment through statistical checks and k-fold analysis also validated the higher precision of BE models over the MLPNN models. Building models that can calculate rheological properties of AAC for different values of input parameters could save a lot of time and money compared to doing the tests in a laboratory. In order to ascertain the required amounts of raw materials of AAC, investigators, as well as businesses, may find the SHAP study helpful.
The impact of poverty and socioeconomic status on brain, behaviour, and development: a unified framework
Authors: Abo Hamza Eid , Tindle Richard , Pawlak Simon , Bedewy Dalia , Moustafa Ahmed A. 
Published: April 2024

Abstract
In this article, we, for the first time, provide a comprehensive overview and unified framework of the impact of poverty and low socioeconomic status (SES) on the brain and behaviour. While there are many studies on the impact of low SES on the brain (including cortex, hippocampus, amygdala, and even neurotransmitters) and behaviours (including educational attainment, language development, development of psychopathological disorders), prior studies did not integrate behavioural, educational, and neural findings in one framework. Here, we argue that the impact of poverty and low SES on the brain and behaviour are interrelated. Specifically, based on prior studies, due to a lack of resources, poverty and low SES are associated with poor nutrition, high levels of stress in caregivers and their children, and exposure to socio-environmental hazards. These psychological and physical injuries impact the normal development of several brain areas and neurotransmitters. Impaired functioning of the amygdala can lead to the development of psychopathological disorders, while impaired hippocampus and cortex functions are associated with a delay in learning and language development as well as poor academic performance. This in turn perpetuates poverty in children, leading to a vicious cycle of poverty and psychological/physical impairments. In addition to providing economic aid to economically disadvantaged families, interventions should aim to tackle neural abnormalities caused by poverty and low SES in early childhood. Importantly, acknowledging brain abnormalities due to poverty in early childhood can help increase economic equity. In the current study, we provide a comprehensive list of future studies to help understand the impact of poverty on the brain.
Grenzüberschreitungen an der Peripherie: Aspektuelle Funktionen von Aktivpartizipien und Verbalsubstantiven im Tschechischen
Authors: Giger Markus , Kocková Jana 
Published: April 2024

Summary
Non-finite verb forms are located at the boundary of the verbal paradigm. On the one hand, they are formed paradigmatically and – if they are not lexicalized – correspond semantically to the underlying verb; on the other hand, they behave syntactically like nominal forms. Their interpretation and thus their treatment in grammars and in corpus annotation differ in individual national philological traditions. In the present text, the behavior of Czech participles and verbal nouns is investigated with respect to the category of verbal aspect. On the basis of excerpts from electronic corpora (Czech National Corpus), it is shown that both participles and verbal nouns express aspectual functions. Even more, they are capable of overstepping boundaries of codification and formal description and actualizing these aspectual functions in concrete contexts. However, participles and verbal nouns do not behave in the same way, but follow certain lines, which are given by differences in codification, formal morphology and syntactic functions.
„Mag es zweideutig klingen“ – zur Bedeutung eines bislang unpublizierten Briefes Andrej Tarkovskijs und dessen Stellung innerhalb der Entstehungs-geschichte von Zapečatlennoe vremja
Authors: Seidel Anne 
Published: April 2024

Summary
Andrej Tarkovskij’s autograph manuscripts and annotated typescripts are archives of change. On the basis of an exemplary passage in a recently surfaced letter by Tarkovskij to Kitty Hunter Blair this article provides a text-critical introduction into the complex history of the creation and relation between the written records of ‘Zapečatlennoe vremja’ – Tarkovskij’s only book on film, which has remained a fragment. The textual witnesses – annotated Typescripts and manuscripts – scattered today among various (private) archives, raise the question of the possibility and form of representation within a reliable critical edition in the original language. This article argues that only scrupulous transcription and the precise exegesis of Tarkovskij’s overwritings, deletions, additions and rearrangements within the textual witnesses will allow an adequate interpretation. A term-historical article appears within the article for hermeneutical reasons: The Stalinist definition of ‘naturalism’ and how it was repressively used against Soviet artists is explained along with its ties to terror. The ‘naturalism’ critique as an accusation in the arts was put forward well beyond the dictator’s death and negatively affected also Tarkovskij’s work for decades. The passage from the letter discussed here, shows how Tarkovskij reflected and reacted to the conditions of Soviet (self-)censorship related to ‘naturalism’ critique. The interpretation this article gives of the passage in Tarkovskij’s letter relies on the analysis of differing textual witnesses of ‘Zapečatlennoe vremja’.
Family firms, hidden champions and regional development
Authors: Suwala Lech , Ahrens Jan-Philipp , Basco Rodrigo 
Published: April 2024

Abstract
This editorial introduces the nexus between family firms, hidden champions, and regional development from an economic geography perspective. Family firms constitute the backbones of most local and regional economies, and some of them are even so-called hidden champions, which are global leaders in their market niches. At the same time, both entities are spatial sources of heterogeneity able to empower regions with difficult-to-imitate competitive and locational advantages that originate from the stickiness of their economic actors. It is mainly an empirical task to prove if this regional distinctiveness results from the structures and embeddings that family firms and hidden champions stand for (e.g., regional persistence and local rooting), and from the practices how these entities are owned, governed, managed (e.g., long-term business relations with [local] suppliers, customers, labour force, international excellence). By outlining three infant research directions on family firms and hidden champions from an economic geography perspective, this editorial frames the field, introduces and locates the contributions in this special issue therein, and calls for a spatially informed view on this rising cross-disciplinary field.
Plato’s Theaetetus end logos of the Digital Humanities
Authors: Janik Piotr 
Published: April 2024

The specifics of the humanities are the study of the human and its offspring, already recalled by Socrates in the “Theaetetus”. The dialogue marks a substantial shift in Plato — the discovery to be attributed to Wincenty Lutosławski, the author of the chronology of Plato’s works — that is, from pre-existent and transcendental ideas to the categories of reason, from philosophy as the “love of wisdom” to the “love of knowledge”. Thus, contrary to the widely held view of the so-called lack of the definition of knowledge in the “Theaetetus”, I argue that the quest for knowledge refers to the logic of thinking — the theme related to Charles S. Peirce’s logic of discovery and still distinct from “technology” — and provides the constitution of the humanities of the information and communication age as the digital humanities.

Challenges of the Research Management Office in Higher Edcuational Institutions (HEIS): Local and Global Perspectives
Authors: Aboh Florence , Barnie Bernard 
Published: April 2024

With the growing interest in managing research and sponsored programmes, HEIs are recognizing the need for research support services. For many HEIs in sub-Saharan Africa, this means up-skilling research administration and management expertise, project management proficiency, and good governance structures by setting up a research management office in these institutions to champion the cause of expanding the institutional research frontier. While subjective evidence suggests that setting up a research management office can be quite difficult, few studies have discussed the specific challenges involved.

To address this gap in the existing body of knowledge, the researchers conducted desk research to (1) understand the role of a research management office in HEIs, (2) identify the challenges of the research management office and the research manager through a purposive sampling of available data on the subject, rank these challenges according to dominance and (4) offer pragmatic recommendations that will aid the office and the manager to deliver on their mandate.

The study addresses challenges associated with the research management office in sub-Saharan Africa and offers a deeper understanding of these challenges as well as chart a course to surmount these challenges and reposition the office and managers of research to effectively and efficiently deliver on their mandate.

The paper wakes up a call for a professional framework for career and skills development among research management practitioners and by extension, the office, and its resources, infrastructure, systems, and procedures needed for effective research management support not only in HEIs in Sub-Saharan Africa but also worldwide.
Myoepithelial Carcinoma of Soft Tissue
Authors: Richards Alexandra R. , Vijayakumar Gayathri , Braun Ankica , Gitelis Steven , Blank Alan T. 
Published: April 2024

Case:
A 40-year-old man was evaluated for a painful mass on his right calf, and a 36-year-old woman presented with a painless mass on her right foot. Final pathology revealed marked nuclear atypia and positivity for S100/SOX10 and AE1/AE3 confirming diagnoses of myoepithelial carcinoma. Both patients underwent surgical resection and are without evidence of local recurrence or metastatic disease at 1-year follow-up.

Conclusion:
Soft-tissue tumors presenting in the extremities warrant careful evaluation and timely histopathologic diagnosis. Myoepithelial carcinomas are rare, aggressive tumors with a propensity for local recurrence and metastasis. Treatment of these tumors should be discussed by a multidisciplinary tumor team.
Bilateral Total Knee Arthroplasties in a Patient with Bilateral Below-Knee Amputations and Osseointegration Limb Replacements
Authors: Al Badi Hamid , Tanzer Michael , Turcotte Robert , Hart Adam 
Published: April 2024

Case:
A 38-year-old man with congenital pain insensitivity underwent bilateral below-knee amputations. After his subsequent bilateral osseointegration (OI) limb replacements, he rapidly developed severe bilateral knee arthritis and varus deformity. In lieu of performing bilateral above-knee amputations, he underwent bilateral staged total knee arthroplasties (TKA) with excellent clinical and radiographic evaluation at 1-year follow-up.

Conclusion:
To address both the limited bone stock and OI implant stem location, TKA after OI limb replacement in congenital pain insensitivity patients can be successfully achieved with a nonkeeled cementless tibial component and augmentation with a tibial cone.
New Oil and Gas Plays in the Cis-Urals
Authors: Sobornov K.O. 
Published: April 2024

Abstract
—The search for oil and gas in folded zones and in the foredeep of the cis-Uralian region for many decades was reduced to testing of easy-to-find closures and reefs located at shallow depths. Many important discoveries were made as a result, but the overall performance of the work remained relatively low. On the one hand, this was due to the poor subsurface imaging of the data for reliable preparation of structures in regions of complex structure. On the other hand, the peculiarities of the development of oil and gas systems in these regions were ignored during the assessment of prospecting sites. In comparison with traditional production hubs centers in the platform regions of the Volga–Ural and Timan–Pechora basins, this distinguishing feature was caused by a thicker sedimentary cover, the variability of its composition and structure, and multiple phases of structural development. Many failures were due to the formation of traps after the passage of the primary migration flow of oil and gas, low capacity of reservoirs, and their fracturing by faults. As shown by interpretation of new geodata using modern knowledge about the oil and gas potential of regions of similar structure, the cis-Uralian region contains poorly studied oil and gas accumulation zones that can contain large deposits. These include blind thrust regions, subsalt traps in development zones of dislocated diapirs, and also stratigraphic and combined traps associated with unconformities and facies changes. The utmost attention is paid to new prospecting objects in the Timan–Pechora basin in which the thickness of the Paleozoic cover has increased. The preparation of new promising objects in these zones has become possible due to new knowledge and better geophysical data.
Community structure of saproxylic arthropods in urban fragmented forests and large-scale forests in a warm-temperate zone of East Asia
Authors: Miyazaki Satoshi , Koike Fumito 
Published: April 2024

Abstract

Saproxylic arthropods play an essential role in the detritus food chains of forest ecosystems by contributing to wood decomposition and nutrient cycling. However,little is known about the effects of urbanization on saproxylic arthropod communities. This study examined saproxylic arthropod communities in various landscapes, ranging from large to fragmented urban forests, and compared the structure and composition of these communities. The results showed that communities could be classified into three types based on species composition and that arthropod community types were correlated with forest size. The fragmented urban forest community contained a large number of individuals of a few facultative saproxylic species, whereas many obligate saproxylic species were present in the large forest community. Rarefaction curves based on the cumulative number of individuals revealed that fragmented urban forest communities had significantly lower species richness than large forested area communities. However, this difference was not significant when the curve was based on the cumulative wood volume. Therefore, large forests must be protected to conserve the overall diversity of saproxylic arthropods. However, the stag beetle,Dorcus rectus,was found to prefer urban fragmented forests over large-scale forests. As this species is popular among Japanese children, it is suitable for encouraging urban children to engage with natural ecosystems.

Published: April 2024

Abstract

The species of Eupatorium chinense L. is an economically important traditional Chinese medicinal plant. The complete chloroplast (cp) genome of the Eupatorium chinense species and a comparative genomic analysis of Eupatorium chinense and its closely related species within the Eupatorieae family are presented in this study. The results indicated that the cp genome had a typical circular structure of 151,393 bp in length, consisting of a long single-copy (LSC) region with 83,044 bp, a short single-copy (SSC) region with 18,295 bp, and two inverted repeat (IR) regions of 50,054 bp. A total of 133 genes were identified, including 37 tRNA genes, 8 rRNA genes and 87 protein-coding genes, with the GC content of 37.6%. The gene content, organization, and GC values found here were comparable to those of the other species of Eupatorieae. Phylogenetic analysis reveals the systematic position of Eupatorium chinense is sister to Eupatorium fortunei Turcz. For the purposes of analysis of this genus identification, evolution, and comparative genomic study, the chloroplast genome sequence of the Eupatorium chinense species offers a useful genetic resource.

Authors: OCCHINO John A. , D.O Jenifer N. BYRNES , Wu Pei-Ying , WALTHER-ANTONIO Marina R. , CHEN Jun 
Published: April 2024

Abstract

This is a single Institute, prospective cohort study. We collected twenty- two postmenopausal women with pelvic organ prolapse planning to undergo vaginal hysterectomy with transvaginal pelvic reconstructive surgery, with or without a concomitant anti-incontinence procedure. Vaginal swabs and urine samples were longitudinally collected at five time points: preoperative consult visit (T1), day of surgery prior to surgical scrub (T2), immediately postoperative (T3), day of hospital discharge (T4), and at the postoperative exam visit (T5). Women experiencing urinary tract infection symptoms provided a sample set prior to antibiotic administration (T6). Microbiome analysis on vaginal and urinary specimens at each time point. Region V3-V5 of the 16S ribosomal RNA gene was amplified and sequenced. Sample DNA was analyzed with visit T1, T2, T5 and T6. Six (27.3%) participants developed postoperative urinary tract infection whose vaginal sample at first clinical visit (T1) revealed beta-diversity analysis with significant differences in microbiome structure and composition. Women diagnosed with a postoperative urinary tract infection had a vaginal microbiome characterized by low abundance of Lactobacillus and high prevalence of Prevotella and Gardnerella species. In our cohort, preoperative vaginal swabs can predict who will develop a urinary tract infection following transvaginal surgery for pelvic organ prolapse.
The influence of selected grain size fractions of coal fly ash on properties of clay-cement mortars used for the flood levees construction

Published: April 2024

Abstract

This study examines the influence of different grain size fractions of coal fly ash on the properties of clay-cement mortars used in flood levee construction. Dry aerodynamic separation and mesh sieving were employed to obtain ultra-fine, fine, and medium fractions of high-calcium and silicious fly ash. The experimental results reveal that the rheological properties of fresh mortars are significantly influenced by these fractions. High-calcium fly ash mortars exhibit high reactivity and rapid viscosity increase, with finer fractions showing the highest reactivity. Silica ashes show increased reactivity in the later stages of suspension hardening. Their spherical shape contributes to reducing internal friction during flow in initial technological operations. Furthermore, the compressive strength of hardened mortars improves as the particle size decreases for both ashes resulting in dense and uniform microstructure. The separation and fractionation of fly ashes contribute to obtaining fractions that influence clay-cement suspension application parameters at different scales. Results show the potential benefits of the separation of ash which can bring advantages in terms of economic viability, engineering performance, and ecological sustainability.
