Published: July 2023

Non-variceal upper gastrointestinal bleeding (NVUGIB) is a common gastroenterological emergency associated with significant morbidity and mortality. Gastroenterologists and other involved clinicians are generally assisted by international guidelines in its management. However, NVUGIB due to peptic ulcer disease only is mainly addressed by current guidelines, with upper gastrointestinal endoscopy being recommended as the gold standard modality for both diagnosis and treatment. Conversely, the management of rare and extraordinary rare causes of NVUGIB is not covered by current guidelines. Given they are frequently life-threatening conditions, all the involved clinicians, that is emergency physicians, diagnostic and interventional radiologists, surgeons, in addition obviously to gastroenterologists, should be aware of and familiar with their management. Indeed, they typically require a prompt diagnosis and treatment, engaging a dedicated, patient-tailored, multidisciplinary team approach. The aim of our review was to extensively summarize the current evidence with regard to the management of rare and extraordinary rare causes of NVUGIB.

TERORISME DI MEDIA SOSIAL: TINJAUAN AKSI DAN RESISTENSI PREVENTIF
Authors: Rohimi
Published: July 2023

Berbicara tentang radikalisme memang sudah banyak kita temui dan dengar di berbagai macam pertemuan diskusi dan worksop. Radikalisme selalu dikaitkan dengan kaum muslim atau orang islam, dimana inti dari tindakan radikal ini memang menginginkan suatu tujuan politik yakni untuk mendirikan negara islam. Sehingga tidak heran jika dunia dihantui oleh kelompok-kelompok radikal bahkan indonesia itu sendiri. Akan tetapi dalam tulisan ini, mempokuskan tindak radikalis pada media sosial atau dunia maya, karena tidak bisa kita pungkiri arti penting dari media internet mampu memberikan kontribusi praktis bagi manusia di seluruh didunia. Sehingga media internet mampu dijangkau oleh semua kalangan  begitu pula dengan kelompok radikal yang memanfaatkan media internet sebagai bentuk alat dalam memperluas anggotanya di seluruh negara belahan dunia, karena dengan internet mampu mempropaganda dan menambahkan anggotanya. Namun seperti halnya kita ketahui, bahwa radikalisme ini sangat membahayakan akibat idelogi yang mereka anut, sehingga negara di seluruh dunia sudah melakukan resistensi preventif atas tindak radikalisme di media sosial dengan memblokir akun-akun media sosial dengan tujuan untuk menstagnasikan penyaluran dan perluasan kelompok radikal.
First steps into the pupillometry multiverse of developmental science
Authors: Calignano Giulia , Girardi Paolo , Altoè Gianmarco
Published: July 2023

Pupillometry has been widely implemented to investigate cognitive functioning since infancy. Like most psychophysiological and behavioral measures, it implies hierarchical levels of arbitrariness in preprocessing before statistical data analysis. By means of an illustrative example, we checked the robustness of the results of a familiarization procedure that compared the impact of audiovisual and visual stimuli in 12-month-olds. We adopted a multiverse approach to pupillometry data analysis to explore the role of (1) the preprocessing phase, that is, handling of extreme values, selection of the areas of interest, management of blinks, baseline correction, participant inclusion/exclusion and (2) the modeling structure, that is, the incorporation of smoothers, fixed and random effects structure, in guiding the parameter estimation. The multiverse of analyses shows how the preprocessing steps influenced the regression results, and when visual stimuli plausibly predicted an increase of resource allocation compared with audiovisual stimuli. Importantly, smoothing time in statistical models increased the plausibility of the results compared to those nested models that do not weigh the impact of time. Finally, we share theoretical and methodological tools to move the first steps into (rather than being afraid of) the inherent uncertainty of infant pupillometry.

Authors: Singla Dr. Raja , Kumar Dr Harish , Kamboj Dr Anjali
Published: July 2023

Defense mechanism (immune system) is a primary function to protect our body from external invaders (bacteria, virus), but in some situations our immune system attacks the body itself and it includes hypersensitivity reaction, autoimmune disorders and immunodeficiency Immune disorder (like SLE) is a dysfunction of immune system. SLE (systemic lupus erythematous) is autoimmune disorder which causes long term chronic inflammation of affected organs leading to degradation in overall quality of life. SLE is much more common in female than male. It may occur at any age, but appears most often in reproductive age. Its manifestation are fatigue, fever, rashes, general discomfort, uneasiness, Hair loss, Mouth sores, Sensitivity to sunlight, swollen lymph node .As discussed above, sign and symptoms of SLE have similarities with pittaadhkiya vatarakta in Ayurveda. An attempt is made to treat SLE with panchkarma procedure like Basti (patoladhi ghrita Anuvasan basti and yastimadhuadi ksheer niruh Basti).
A Pragmatic Study of Refusal Speech Act: A Gender Perspective
Authors: Abdulrazzaq Abdulzahra Dr. Mushtaq
Published: July 2023

In EFL context, there comes many situations in which we need to refuse an offer, suggestion, invitation or request. And because the choice of the refusal strategy may vary in terms of gender the current study, thus, aimed to reveal gender variations in the use of the speech act of refusal. The study sampled 86 EFL learners split equally into 43 males and females. Three quantitative research questions guided the study. The data were collected by means of DCT designed for this end. These data were input and analysed using SPSS and Excel sheets for descriptive and inferential statistics. The study revealed that there is a partial gender variation at these two refusal strategies which are: flat refusal and expressing regret. Both of which were used dominantly by the males. In in terms of directness, it is found that the males use more direct refusals than the females. It was also revealed that most frequent refusal strategy expressed by Iraqi EFL learners is expressing regret.
The Weak Level of Iraqi Human Capital According to the Indicators of the World Bank and its Impact on Economic Growth
Authors: Kareem Ali Maha
Published: July 2023

The aim of this study was to shed light on the weakness of Iraq in utilizing its human capital and to examine the future productivity of the Iraqi workforce and its implications for long-term economic growth. The study also sought to identify the indicators used by the World Bank to measure human capital investment. Therefore, the research problem focused on the crisis of Iraqi human capital and the low productivity of the next generation of the workforce due to the lack of attention, inadequate investment, and insufficient training and development programs that align with the rapid technological advancements. The study concluded that Iraq possesses a demographic dividend, but this dividend is being wasted, as the human resources and capabilities are not being utilized effectively to enhance future economic growth. This leads to the creation of a generation incapable of keeping up with the rapid development, primarily due to low expenditure on education and healthcare compared to other developing countries. Secondly, the study identified the mismatch between the outputs of education and the needs and requirements of the labor market, which ultimately results in the limited contribution of human capital towards achieving long-term productivity. Consequently, Iraqi human capital lags behind in terms of development, creativity, and innovation compared to the rest of the world. Moreover, the mismatch between educational outputs and the needs and requirements of the labor market leads to a diminished contribution of human capital to achieving long-term productivity. This results in Iraqi human capital falling behind in terms of development, creativity, and innovation compared to the advancements made by countries worldwide.

International Auditing Standard (700) and its Role in Improving the Auditor's Report1
Authors: Jabbar Ali Hadeel
Published: July 2023

To ensure that the auditor's report achieves its main objective, careful attention must be given to its content and language. The report should be easily understandable to users of financial data and align with the objectives of professional bodies supported by studies and research. The adoption of International Auditing Standard (700) by professional bodies plays a crucial role in shaping the auditor's report. In the context of Iraq, where this research was conducted in the Federal Office of Financial Supervision and external audit offices, auditors' compliance contributes to the consistency of financial report data. The study aimed to clarify the concept of the auditor's report, identify the factors influencing its quality, and examine the impact of implementing International Auditing Standard (700) on enhancing the auditor's report in the Iraqi setting. A total of 100 questionnaires were distributed, and 90 valid responses were collected for statistical analysis, indicating a response rate of 90%. The data was analyzed using the SPSS program to extract research results based on the sample responses. The research yielded several conclusions, the most important of which is that the auditor's responsibility is to express an opinion on the financial data based on the audit work conducted in accordance with international auditing standards. In light of these findings, the researcher recommends that the management, as the primary party responsible for presenting the financial data fairly, carefully review the reports before sharing them with stakeholders to ensure accuracy, completeness, and absence of errors or omissions
The Impact of Red Model on Enhancing the Iraqi EFL University Students' Performance Skills in Writing
Authors: Al Khanaifsawy Abdullah Najim Abd
Published: July 2023

Writing is a powerful tool for communicating and expressing one's feelings, ideas, and opinions to others. Thinking skills might help you improve your writing and study more effectively. The quality of the instructional method, practices, and learning environment all play a role in preparing students to be great writers. The RED model gives forth a method for learning critical thinking and strengthening each of the important abilities that aid learners in writing production. The RED model is a three-step learning process that includes Recognize Assumptions, Evaluate Information, and Draw Conclusions. This model uses an easy-to-remember acronym to give a systematic approach to critical thinking. The first stage is to recognize preconceptions, which aids learners in identifying information gaps and broadening their perspectives on topics. The second stage, evaluating information, includes objectively and properly interpreting information as well as challenging the validity of supporting evidence. The final stage is to draw a conclusions Learners who have mastered this skill are able to combine disparate pieces of information to arrive at conclusions that logically follow from the evidence.The difficulty with this project stems from the fact that Iraqi EFL composition writing instructors place a strong emphasis on traditional approaches while neglecting practical issues. As a result, Iraqi EFL secondary school students do poorly in composition writing and do not use higher order thinking abilities in their writing. As a result, a new paradigm of thinking is required to highlight the practical components of teaching composition writing.
A Semantic Study of the Word “Furqan” in Some Quaanic Selected Verses
Authors: Abd Al Khanaifsaw Abdullah Najim
Published: July 2023

It is worth mentioning that Semantics is the bridge by which meaning can be studied and texts can be understood and, finally, the intentions and implications of divine revelations can be discovered. The present study makes use of a methodical approach to deal with two essential issues: firstly, the semantic analysis of “Furqan” will be carried out in the context of the holy Quran’s verses by way of a semantic study based on the linguistic context and investigation of the paradigmatic and syntagmatic relationships. Secondly, semantics will be deployed in reply to the skepticisms regarding the conceptualization of the word Furqan in the Holy Quran as stated in the book Letters for the Prophet Muhammad: A Research on the Roots of the Quran. In line with investigations, it can be said that Furqan was syntagmatically used with some words like piety and guidance and it was interchangeably used with words such as scale, Quran and the book. As a final definition of Furqan, we suggest that it is not of a lexical character and that it is by exercising the divine teachings that one might gain a “light” by means of which one can distinguish the right from the wrong and easily overcome the calamities and conspiracies of the time. Accordingly, the claim by the author of the book Letters for the Prophet Muhammad to the effect that the term “Furqan” refers to a book other than the present Quran is rejected.

Authors: Mohamed Zahraa Adnan , Jaafar Eman Adil
Published: July 2023

The study of language and ecology is a recent topic in linguistic studies. The current study investigates language patterns that are employed to describe the powerful role of nature. The main aims of this study are: to conduct an ecostylistic analysis of some selected extracts from Amitav Ghosh's novel, The Hungry Tide, by using a functional technique to examine the type of agency and transitivity processes that are presented in these extracts. Furthermore, it aims at highlighting the ecological linguistic traits in the data. The eclectic method is based on Systemic Functional Grammar (SFG) and Zurru (2017). Stylistic tools aid to reveal the connection between human and non-human participants. The chosen extracts are ecostylistically examined to show the relationship that may be built between environmental studies and stylistics. The main contribution of this study is to link the importance of the environment and its issues to human existence in literary language. Moreover, ecological stylistic features and the author's word choices that portray the role of nature are identified in the literary text.

Authors: Al-Hajmee Ali Abdul Mohsin
Published: July 2023

For both instructors and students, a multimodal approach in the classroom may inspire creativity. It does not necessarily rely on technology and instead makes use of the existing kinaesthetic, auditory, and visual modalities. In this essay, we shall quickly define modes and trace the history of multimodal research. We can recognize modes through a multimodal lesson that incorporates video and see how they connect to both modern culture and certain cognitive processes. This combination can improve the learning environment by allowing for flexibility and creativity in teacher-student interaction.

Conclusion: By applying machine learning into Covid-19, length of stay estimates can be made with more accuracy, allowing for more effective patient management.
Maternal Behçet Hastalığının Fetal Adrenal Bez Boyutlarına Etkisi
Authors: UYAN HENDEM Derya , SAHİN Dilek
Published: July 2023

Amaç: Maternal Behçet Hastalığı (BH) ile komplike gebeliklerde artmış inflamasyonun fetal adrenal bezin erken olgunlaşmasına neden olabileceğini, dolayısıyla fetal adrenal bez boyutunun değişebileceğini hipoteze ederek, maternal BH’li gebeliklerde fetal adrenal bez boyutlarını incelemeyi amaçladık.

Gereç ve Yöntemler: Kesitsel tasarımda ki bu çalışma, Mayıs 2022-Mayıs 2023 tarihleri arasında Ankara Şehir Hastanesi perinatoloji kliniğinde yürütüldü. Çalışmaya 31-34 gebelik haftalarında başvuran BH tanısı almış 21 gebe ve gebelik yaşı vaka grubu ile eşleştirilmiş ve rastgele seçilmiş 63 sağlıklı gebe dahil edildi. Her iki adrenal bez ile fetal zonun genişliği ve uzunluğu transvers kesitte ölçülerek uzunluk x genişlik x π formülü ile transvers adrenal alan (TAA), transvers fetal zon alanı (FZA) ve fetal zon alanının transvers adrenal alana oranı (FZA/TTA) hesaplandı. Vaka ve kontrol grupları arasında ayrıca atak geçiren ve geçirmeyen BH alt gruplarında fetal adrenal ölçümler karşılaştırıldı.

Bulgular: Sol adrenal bezde toplam adrenal genişlik, TTA, fetal zon genişlik ve FZA vaka grubunda anlamlı olarak yüksek bulundu. Ayrıca sol FZA/TTA oranı vaka grubunda istatistiksel olarak anlamlı oranda yüksek saptandı. Sağ adrenal bezde ise fetal zon genişliği, FZA ve FZA/TTA oranı vaka grubunda anlamlı oranda yüksek izlendi. Ayrıca atak geçiren grupta sol adrenal bezde fetal zon genişliği, FZA ve FZA/TTA oranı anlamlı ölçüde yüksek ve sağ adrenal bezde ise toplam adrenal uzunluk, TTA, fetal zon genişliği ve FZA istatiksel olarak anlamlı oranda yüksek izlendi.

Sonuç: Maternal BH ile komplike gebeliklerde fetal adrenal bez boyutları etkilenebilmektedir. Bu etkinin daha çok adrenal bezin fetal zon bölümünde olduğu ve gebeliğinde atak geçiren grupta daha belirgin olduğu görülmektedir. BH gebeliklerinde artmış inflamasyon ve sitokin seviyeleri nedeniyle intrauterin strese maruz kalan fetuslarda adrenal bezin daha erken matürasyonu söz konusu olabilir.
HOW TO MAKE URBAN RENEWAL SUSTAINABLE? PATHWAY ANALYSIS BASED ON FUZZY-SET QUALITATIVE COMPARATIVE ANALYSIS (FSQCA)
Authors: Huang Yijing , Wei Wanyue , Ferreira Fernando A. F.
Published: July 2023

Even though urban renewal has attracted much attention in recent years, relatively few studies focus on the sustainability of urban renewal projects, which is surprising given the associated economic benefits. To fill this gap, we review 31 typical cases of urban renewal in China that have existed for over 10 years and utilize fuzzy set qualitative comparative analysis (fsQCA) to identify causal configurations that lead to a high level of stakeholder satisfaction. Our findings show that: (1) there are four antecedent configurations that lead to the sustainability of urban renewal of urban renewal (these are: ~ preservation of history and culture * differentiation * project reformation * ~ incremental innovation; ~ preservation of history and culture * differentiation * commercial publicity * incremental innovation; preservation of history and culture * commercial publicity * ~ project reformation * incremental innovation; and preservation of history and culture * differentiation * ~ commercial publicity * project reformation * incremental innovation); (2) compared with other conditions, differentiation and incremental innovation play more important roles in the sustainability of urban renewal; and (3) not only the improvement of the environment but also the operation and management of projects should be considered carefully. This paper contributes to urban renewal literature and offers practical suggestions for sustainable urban development.
A Simple Spectroscopic Technique to Identify Rejuvenating Galaxies
Authors: Zhang Junyu , Li Yijia , Leja Joel , Whitaker Katherine E. , Nersesian Angelos , Bezanson Rachel , van der Wel Arjen
Published: July 2023

Rejuvenating galaxies are unusual galaxies that fully quench and then subsequently experience a “rejuvenation” event to become star-forming once more. Rejuvenation rates vary substantially in models of galaxy formation: 10%–70% of massive galaxies are expected to experience rejuvenation by z = 0. Measuring the rate of rejuvenation is therefore important for calibrating the strength of star-formation feedback mechanisms. However, these observations are challenging because rejuvenating systems blend in with normal star-forming galaxies in broadband photometry. In this paper, we use the galaxy spectral energy distribution-fitting code Prospector to search for observational markers that distinguish normal star-forming galaxies from rejuvenating galaxies. We find that rejuvenating galaxies have smaller Balmer absorption line equivalent widths (EWs) than normal star-forming galaxies. This is analogous to the well-known “K+A” or post-starburst galaxies, which have strong Balmer absorption due to A-stars dominating the light: in this case, rejuvenating systems have a lack of A-stars, instead resembling “O—A” systems. We find star-forming galaxies that have Hβ, Hγ, and/or Hδ absorption EWs ≲3 Å corresponds to a highly pure selection of rejuvenating systems. Interestingly, while this technique is highly effective at identifying mild rejuvenation, “strongly” rejuvenating systems remain nearly indistinguishable from star-forming galaxies due to the well-known stellar outshining effect. We conclude that measuring Balmer absorption line EWs in star-forming galaxy populations is an efficient method to identify rejuvenating populations, and discuss several techniques to either remove or resolve the nebular emission which typically lies on top of these absorption lines.
The Direction of the Flow of Interstellar Neutral H Based on Photometric Observations from SOHO/SWAN

Published: July 2023

Interstellar neutral hydrogen flows into the heliosphere as a mixture of the primary and secondary populations from two somewhat different directions due to splitting occurring in the magnetized outer heliosheath. The direction of the inflow of interstellar neutral H observed in the inner heliosphere, confronted with that of the unperturbed flow of interstellar neutral helium, is important for understanding the geometry of the distortion of the heliosphere from axial symmetry. It is also needed for facilitating remote-sensing studies of the solar wind structure based on observations of the helioglow, such as those presently performed by SOHO/SWAN, and in the near future by IMAP/GLOWS. In the past, the only means to measure the direction of the flow of interstellar hydrogen were spectroscopic observations of the helioglow. Here, we propose a new method to determine this parameter based on a long series of photometric observations of the helioglow. The method is based on purely geometric considerations and does not depend on any model and absolute calibration of the measurements. We apply this method to sky maps of the helioglow available from the SOHO/SWAN experiment and derive the mean longitude of the flow of interstellar hydrogen. We obtain 253.°1 ± 2.°8, which is in perfect agreement with the previously obtained results based on spectroscopic observations.
When the Stars Align: A 5σ Concordance of Planetary Nebulae Major Axes in the Center of Our Galaxy
Authors: Tan Shuyu , Parker Quentin A. , Zijlstra Albert A. , Ritter Andreas , Rees Bryan
Published: July 2023

We report observations of a remarkable major axes alignment nearly parallel to the Galactic plane of 5σ significance for a subset of bulge “planetary nebulae” (PNe) that host, or are inferred to host, short-period binaries. Nearly all are bipolar. It is solely this specific PN population that accounts for the much weaker statistical alignments previously reported for the more general bulge PNe. It is clear evidence of a persistent, organized process acting on a measurable parameter at the heart of our galaxy over perhaps cosmologically significant periods of time for this very particular PN sample. Stable magnetic fields are currently the only plausible mechanism that could affect multiple binary star orbits as revealed by the observed major axes orientations of their eventual PNe. Examples are fed into the current bulge PN population at a rate determined by their formation history and mass range of their binary stellar progenitors.
Evidence for a Black Hole Spin–Orbit Misalignment in the X-Ray Binary Cyg X-1
Authors: Zdziarski Andrzej A. , Veledina Alexandra , Szanecki Michał , Green David A. , Bright Joe S. , Williams David R. A.
Published: July 2023

Recently, the accretion geometry of the black hole X-ray binary Cyg X-1 was probed with the X-ray polarization. The position angle of the X-ray-emitting flow was found to be aligned with the position angle of the radio jet in the plane of the sky. At the same time, the observed high polarization degree could be obtained only for a high inclination of the X-ray-emitting flow, indicating a misalignment between the binary axis and the black hole spin. The jet, in turn, is believed to be directed by the spin axis; hence, a similar misalignment is expected between the jet and binary axes. We test this hypothesis using very long (up to about 26 yr) multiband radio observations. We find a misalignment of 20°–30°. However, contrary to the earlier expectations, the jet and binary viewing angles are found to be similar, while the misalignment is seen between the position angles of the jet and the binary axis on the plane of the sky. Furthermore, the presence of the misalignment calls into question our understanding of the evolution of this binary system.
The “Super-Active” Accretion Phase of T CrB has Ended
Authors: Munari Ulisse
Published: July 2023

The symbiotic recurrent nova T CrB erupted for the second and last recorded time in 1946. Following the outburst, the accretion rate onto its WD has remained rather low with only occasional and minor flaring episodes, until in late 2014 it entered a “super-active” phase (SAP) that peaked in 2016 April: the flux radiated by Balmer lines increased by two orders of magnitude, accompanied by the appearance of strong He i, He ii, and many other emission lines. Following the sharp maximum, the intensity of the emission lines has been steadily decreasing, reaching back to pre-SAP levels by mid-2023. The end of SAP is also confirmed by the drop of B-band brightness to pre-SAP conditions and the simultaneous re-appearance of a large-amplitude flickering. This suggests that the accretion disk has emptied from the extra material that has driven the “super active” state and has completed its transfer onto the WD, setting the stage for a new and probably imminent nova eruption.

The Asian walnut moth, Garella musculana (Erschov, 1874) (Lepidoptera, Nolidae) is an alien pest originating from Central Asia and is now spreading in Europe, attacking walnut trees. In this study, we updated the current distribution of G. musculana, focusing on the Italian range, where it was reported for the first time in 2021. Field surveys showed an extensive distribution of G. musculana in northern Italy, particularly in the Veneto Region. In this area, the Asian walnut moth developed on English and black walnut, attacking almost exclusively tree shoots. Based on current distribution data, further investigations are required in the nearby regions as well as in those that were less surveyed. Lastly, it is imperative to conduct more studies on insect biology and the impact on walnut production.

Published: July 2023

The populations usually attributed to Solenopsis bivonae (Tineo) M.B.Crespo, Serra & A.Juan are investigated from a taxonomical and morphological viewpoint. Within this species complex, four new subspecies occurring in Sicily and Calabria are recognized, such as subsp. bivonae, subsp. madoniarum, subsp. peloritana and subsp. brutia. In addition, a new species from Cyprus described as S. meikleana and S. bacchettae from Sardinia must be included in this group. The synonymy, typification, description, seed testa morphology, chorology, ecology, illustrations, conservation status, and examined specimens for each taxon are provided. Besides, the analytical keys, distribution maps, and phytosociological arrangement regarding these taxa are given too.
Two new species of Acanthobothrium Blanchard, 1848 (Cestoda, Onchoproteocephalidea) from Urobatis jamaicensis (Cuvier, 1816) (Elasmobranchii, Batoidea, Myliobatiformes) of the Mexican Caribbean

Eight specimens of Urobatis jamaicensis were collected from four localities of the Yucatan Peninsula, Mexico, of which four specimens were infected with cestodes of two new species of Acanthobothrium. Acanthobothrium garciaprietoisp. nov. differs from congeners by a combination of characters including the size of the scolex and bothridia, length of the cephalic peduncle, length of the axial and abaxial prongs and total length of the abaxial prongs of the hooks, size of the cirrus sac and testes in mature proglottids, and the total number of proglottids. The most prominent characteristic distinguishing A. pulidofloresaesp. nov. from other species of the Atlantic Ocean/Caribbean Sea/Gulf of Mexico is the form of the scolex, which has the “clover leaf” configuration. In addition, it can be distinguished by the total length of the worm, total number of proglottids, small accessory suckers, the form of the bothridia, length of the axial and abaxial prongs and total abaxial prong length of hooks, and the number of testes. According to the current category scheme, A. garciaprietoisp. nov. and A. pulidofloresaesp. nov., belong to categories 1 and 5, respectively.
Terrestrial crustaceans (Arthropoda, Crustacea): taxonomic diversity, terrestrial adaptations, and ecological functions
Authors: Marin Ivan N. , Tiunov Alexei V.
Published: July 2023

Terrestrial crustaceans are represented by approximately 4,900 species from six main lineages. The diversity of terrestrial taxa ranges from a few genera in Cladocera and Ostracoda to about a third of the known species in Isopoda. Crustaceans are among the smallest as well as the largest terrestrial arthropods. Tiny microcrustaceans (Branchiopoda, Ostracoda, Copepoda) are always associated with water films, while adult stages of macrocrustaceans (Isopoda, Amphipoda, Decapoda) spend most of their lives in terrestrial habitats, being independent of liquid water. Various adaptations in morphology, physiology, reproduction, and behavior allow them to thrive in virtually all geographic areas, including extremely arid habitats. The most derived terrestrial crustaceans have acquired highly developed visual and olfactory systems. The density of soil copepods is sometimes comparable to that of mites and springtails, while the total biomass of decapods on tropical islands can exceed that of mammals in tropical rainforests. During migrations, land crabs create record-breaking aggregations and biomass flows for terrestrial invertebrates. The ecological role of terrestrial microcrustaceans remains poorly studied, while omnivorous macrocrustaceans are important litter transformers and soil bioturbators, occasionally occupying the position of the top predators. Notably, crustaceans are the only group among terrestrial saprotrophic animals widely used by humans as food. Despite the great diversity and ecological impact, terrestrial crustaceans, except for woodlice, are often neglected by terrestrial ecologists. This review aims to narrow this gap discussing the diversity, abundance, adaptations to terrestrial lifestyle, trophic relationships and ecological functions, as well as the main methods used for sampling terrestrial crustaceans.
A topological based feature extraction method for the stock market
Authors: Chang Chen , Lin Hongwei
Published: July 2023

We proposed a topology-based method for pre-processed time series data extracted from stock market data. The topology features are extracted from data after denoising and normalization by using a version of weighted Vietoris-Rips complex. We compare the features from bullish, bearish and normal periods of the Chinese stock market and found significant differences between the features extracted from the groups. Based on the previous research mentioned in the context, we proposed a topology-based stock market index which has the ability to distinguish different stages of the stock market and forewarn stock market crashes.

The best way to achieve sustainable construction is to choose materials with a smaller environmental impact. In this regard, specialists and architects are advised to take these factors into account from the very beginning of the design process. This study offers a framework for selecting the optimal sustainable building material. The core goal of this article is to depict a novel structure of a neutrosophic soft expert set hybrid called an interval-valued neutrosophic soft expert set for utilization in construction supply chain management to select a suitable supplier for a construction project. This study applies two different techniques. One is an algorithmic technique, and the other is set-theoretic. The first one is applied for the structural characterization of an interval-valued neutrosophic expert set with its necessary operators like union and OR operations. The second one is applied for the construction of a decision-making system with the help of pre-described operators. The main purpose of the algorithm is to be used in supply chain management to select a suitable supplier for construction. This paper proposes a new model based on interval-valued, soft expert and neutrosophic settings. In addition to considering these settings jointly, this model is more flexible and reliable than existing ones because it overcomes the obstacles of existing studies on neutrosophic soft set-like models by considering interval-valued conditions, soft expert settings and neutrosophic settings. In addition, an example is presented to demonstrate how the decision support system would be implemented in practice. In the end, analysis, along with benefits, comparisons among existing studies and flexibility, show the efficacy of the proposed structure.
On simultaneous characterizations of partner-ruled surfaces in Minkowski 3-space
Authors: Li Yanlin , Eren Kemal , Ersoy Soley
Published: July 2023

In this study, the partner-ruled surfaces in Minkowski 3-space, which are defined according to the Frenet vectors of non-null space curves, are introduced with extra conditions that guarantee the existence of definite surface normals. First, the requirements of each pair of partner-ruled surfaces to be simultaneously developable and minimal (or maximal for spacelike surfaces) are investigated. The surfaces also simultaneously characterize the asymptotic, geodesic and curvature lines of the parameter curves of these surfaces. Finally, the study provides examples of timelike and spacelike partner-ruled surfaces and includes their graphs.
