Authors: Görgel Büşra , Ege İlhan
Published: September 2024

E7 ülkeleri pay piyasalarında Etkin Piyasa Hipotezi ile (EPH) Adaptif Piyasa Hipotezi’nin (APH) geçerliliğinin araştırılmasının amaçlandığı mevcut çalışmada, 12.10.1997- 04.02.2024 yıllarındaki haftalık veriler kullanılmıştır. EPH ile APH’nin geçerli olup olmadığını belirlemek için veri seti P1, P2, P3, P4 olmak üzere dört farklı alt dönemlere ayrılmıştır. Analiz döneminde E7 ülkelerinin pay piyasalarında fiyatların tahmin edilebilirliğinin değişkenliğini sınamak için standart ve yapısal kırılmalı birim kök testleri olan ADF, PP ve Zivot Andrews testi, varyans oranı testi, BDS testi, AR-MA modeli, otokorelasyon ve ARCH-LM değişen varyans testi kullanılmıştır. Jarque-Bera (J-B) normallik testinden ulaşılan bulgular, Çin, Brezilya, Meksika, Endonezya, Rusya, Türkiye pay piyasalarında dönemlerin tamamında etkinliğin olmadığı yani Etkin Piyasa Hipotezi (EPH) ile APH’nin geçerli olmadığı ancak Hindistan pay piyasasında APH’nin geçerli olduğu belirlenmiştir. Hem ADF, PP hem de Zivot Andrews birim kök testlerine göre tüm dönemlerde E7 ülkeleri pay piyasaları getiri serilerinin durağan oldukları ve EPH ile APH’nin geçerli olmadığı tespit edilmiştir. Uygulanan Varyans oranı testi sonuçları da birim kök testi sonuçlarıyla benzerlik göstermektedir ve bu teste göre de ülkelerin pay piyasalarında EPH ve APH geçerli değildir. BDS testiyle de Çin, Hindistan, Meksika, Endonezya, Rusya, Türkiye pay piyasalarında EPH ve APH’nin geçerli olmadığı, Brezilya’da ise APH’nin geçerli olduğu ortaya çıkarılmıştır. ARMA modeli sonuçlarına göre dönemlerin tümü için EPH ile APH’nin geçerliliğinin olmadığı ve son olarak uygulanan otokorelasyon ve ARCH-LM değişen varyans testleriyle de etkinliğin dönemler içerisinde değiştiği ve dolayısıyla E7 ülkelerinin pay piyasalarında APH’nin geçerli olduğu belirlenmiştir. Analiz sonuçları değerlendirildiğinde E7 ülkeleri pay piyasalarının davranışlarını açıklamada EPH’ye oranla APH’nin daha başarılı sonuç gösterdiğini söylemek mümkündür.
In the Context of War Theories in International Relations, the Causes of Societies' Defeat and Victory in Ibn Khaldûn's Philosophy
Authors: Yaşar Ümütlü Ayşe
Published: September 2024

In this article, the causes that lead states to war, defeat and triumph in Ibn Khaldun's thought will be discussed. Ibn Khaldun adopted an approach to explain wars with social, historical, political and economic factors. Frankly, it is a prerequisite for understanding factual facts that Ibn Khaldun draws attention to the historical context of the issues he wants to explain and predicts future events by analyzing past events and wars. Analyzing historical facts based on this assumption is an important part of his methodology. In his approach, wars are analyzed not only through military strategy but also through their social, historical, geographical, political and economic contexts. Therefore, in this article, his thoughts are presented not only from a state-centered and single-actor approach, but also from a civilization-oriented perspective, in order to help us understand the complexity of wars from the perspective of international relations. The article primarily focuses on the war experience in Ibn Khaldun's life. Then, according to his theory of war, the reasons why societies fight, and then the reasons for victory and defeat, are determined. Finally, Ibn Khaldun's theory is compared in the context of classical war theories in the history of thought and modern war theories.
Stereoactive Electron Lone Pairs Facilitate Fluoride Ion Diffusion in Tetragonal-BaSnF4
Authors: Lian Xiliang , Dambournet Damien , Salanne Mathieu
Published: September 2024

Solid state ionic conductors are of primary importance for the design of tomorrow's batteries. In lithium ion or sodium ion-based materials, the alkali cations diffuse through three-dimensional channels consisting of interconnected tetrahedral or octahedral sites with low free energy barriers between them. Fluoride ion conductors stand out in this landscape since the materials with the highest conductivities belong to the MSnF4 family (in which M2+ is a divalent cation), which structure is layered and characterized by double-layers of Sn2+ and M2+ cations along a given direction. Importantly, these materials display stereoactive electron lone pairs (LPs) that seemingly play an important role not only in stabilizing of the Sn-Sn layer but also in modulating the fluoride ion diffusive behavior. However, despite previous experimental and simulation studies, the involvement of the LPs in the fluoride ions conduction mechanism remains to be quantitatively understood. In this work, we simulate the BaSnF4 tetragonal structure using machine learning-based molecular dynamics, in which the interaction potential is trained on density functional theory data. We investigate the role of the Sn-LP-Sn layer in lowering the diffusion energy landscape. In particular, we show how the F- ions jump across this layer occur much more frequently than in the Ba-F-Ba one, resulting in the formation of vacancies in the Ba-Sn layers. Concurrently, the LPs stereochemical activity fluctuates to accommodate the F ions jumping. In addition, the presence of the LP layer enhances the flexibility of the Sn ions, which leads to an increase of the two-dimensional diffusion by several orders of magnitude. These results contribute to the understanding of the interplay between LPs and ionic diffusion, helping to explain the good performance of the material in fluoride-ion batteries.

Published: September 2024

Herein, we developed the mechanosynthesis of ruthenium trisbipyridyl complexes. Such complexes can be difficult to prepare in solution, with long reaction times and average yields. With ball-milling, less than 3.5 hours of milling were sufficient to obtain the complexes in high yield. Such complexes were then evaluated as catalysts in the light-promoted mechanochemical reductive dehalogenation reaction. In addition to working under solvent-less conditions, the use of a Hantzsch amide instead of the classical ester allowed to drastically simplify the purification of the final compounds.
Late-stage Minimal Labeling of Peptides and Proteins for Real-time Imaging of Cellular Trafficking
Authors: Nadal-Bufi Ferran , Nithun Raj V. , de Moliner Fabio , Lin Xiaoxi , Habiballah Shaimaa , Jbara Muhammad , Vendrell Marc
Published: September 2024

The cellular uptake routes of peptides and proteins are complex and diverse, often handicapping therapeutic success. Understanding their mechanisms of internalization requires chemical derivatization with approaches that are compatible with wash-free and real-time imaging. In this work, we developed a new late-stage labeling strategy for unprotected peptides and proteins, which retains their biological activity while enabling live-cell imaging of uptake and intracellular trafficking. S-bridged nitrobenzodiazoles were selectively incorporated into Cys residues of both linear and cyclic peptides via Pd-mediated arylation with good yields and high purities. The resulting labeled peptides are chemically stable under physiological conditions and display strong fluorogenic character for wash-free imaging studies. We utilized this approach to prepare native-like analogues of cell-penetrating peptides and performed time-course analysis of their internalization routes in live cells by fluorescence lifetime imaging. Furthermore, we applied our strategy to label the chemokine protein mCCL2 and monitor its internalization via receptor-mediated endocytosis in live macrophages. This study provides a straightforward strategy for late-stage fluorogenic labeling of intact peptides and small proteins and direct visualization of dynamic intracellular events.
Unveiling the Impact of Impurity Phases on the Electrochemical Performance of Cobalt-Free Analogs of (Mg0.2Co0.2Ni0.2Cu0.2Zn0.2)O as anode for Lithium-ion Batteries
Authors: Tegomoh Modeste , Co Anne
Published: September 2024

Micrometer-size particles of the pure single-phase rock salt multi-metals oxide, (Mg0.2Co0.2Ni0.2Cu0.2Zn0.2)O, have demonstrated long-term cycling stability and excellent rate performance as an anode for lithium-ion batteries. Such a feat has only been achieved with the nanostructuring of binary transition metal oxides. This success has led to the preparation of several pure single-phase spinel multi-metal oxides with significantly higher capacities. A common belief regarding these complex oxides is that the pure single-phase is a prerequisite for their outstanding electrochemical performance. Deviation from a pure single-phase is thought to harm their electrochemical performance. Here, we prepare and characterize the cobalt-free analogs of (Mg0.2Co0.2Ni0.2Cu0.2Zn0.2)O using a traditional solid-state synthesis method by replacing cobalt with iron and manganese to give (Mg0.2Fe0.2Ni0.2Cu0.2Zn0.2)O and (Mg0.2Mn0.2Ni0.2Cu0.2Zn0.2)O respectively. These analogs were prepared in an air and an argon atmosphere to yield several compositions with different mixtures of crystalline secondary phases. The electrochemical performance of the pure single-phase (Mg0.2Co0.2Ni0.2Cu0.2Zn0.2)O is used as a benchmark to compare the performance of the cobalt-free multi-phase analogs. The results indicate that although these cobalt-free analogs are not pure single-phase materials, their electrochemical performance is similar to that observed with (Mg0.2Co0.2Ni0.2Cu0.2Zn0.2)O, suggesting that a pure single-phase might not be a prerequisite for an excellent electrochemical performance for these complex multi-metal oxides.

Academic work and institutional diversity in Canada
Authors: Bégin-Caouette Olivier , Béland Sébastien , Karram Stephenson Grace , Jones Glen A. , Metcalfe Amy Scott
Published: September 2024

The objective of this article is to determine if the work of full-time professors in Canada varies depending on the type of universities in which they are employed. A nonparametric comparison of multivariate samples based on data from the Academic Profession in the Knowledge Society (APIKS) survey was used to examine faculty perceptions of their academic work. The results show statistically significant, albeit minimal, differences between primarily undergraduate, comprehensive, and research-intensive institutions. This article confirms that, to a small extent, institutional diversity in Canada is mirrored in academic work, and argues that both vertical and horizontal forms of diversity may exist simultaneously depending on the relative value granted to specific academic activities.
“They are just five-year-old boys”: Examining the role of childhood innocence in the early normalization of sexual violence
Authors: Prioletta Jessica
Published: September 2024

The purpose of this article is to examine how the discourse of childhood innocence masks the ways in which sexual violence by boys against girls is perpetrated in kindergarten. Findings from a year-long ethnographic study conducted in two Canadian kindergarten classrooms show that narrow understandings of gender and sexuality in childhood obscure schools’ responses to problematic gendered behaviors enacted by certain boys. The author contends that in failing to attend to gender and sexuality with young children, kindergarten education may contribute profoundly to the early normalization of sexual violence. The article concludes with a discussion on the role that kindergarten education can play in countering sexual violence inside and outside of schools.
Swerve & Shift: The lived experience of Canadian faculty teaching through a pandemic
Authors: McDonnell Maggie , Reid Erin
Published: September 2024

During the COVID-19 pandemic, which began to affect Canadian universities and colleges in March 2020, educators were asked to make a sudden transition, or swerve, to teaching remotely. Subsequently, these same teachers made the shift to teaching remotely longer term, through the fall and winter of 2020-21; the pandemic continued to affect higher education into 2022. Through interactive interviews, the authors have woven together the individual experiences of teachers in higher education across Canada, and found that these teachers faced unprecedented challenges, as well as unimagined silver linings. Based on Porges’ (1995) model of polyvagal theory, the authors suggest that digital communities of practice (Donaldson 2020) provided a muchneeded site of social engagement to mitigate trauma in these unprecedented times.

The Association Between Daily Physical Activity and Risk of Hypertension in Middle-Aged and Older Adults: A Nationwide Cohort Study in China
Authors: Zhang Junhua , Rong Jie , Zhang Hui , Yan Yongmei
Published: September 2024

Physical activity (PA) plays a key role in the treatment of hypertension, and moderate to vigorous PA has been documented to lower the risk of developing hypertension. However, dose-response relationships between PA and hypertension are not consistent, and little is known about this relationship within the Chinese middle-aged and older people. We investigated the relationship between PA and hypertension within this population using China Health and Nutrition Survey 1991–2015 data. Physical activity was expressed in terms of the metabolic equivalent task (MET) and participants were divided into groups according to quartiles, namely, Q1 (< 32.97 METs-h/w), Q2 (32.97–60.38 METs-h/w), Q3 (60.38–98.95 METs-h/w), and Q4 (> 98.95 METs-h/w). Compared with the Q1 group, the odds ratio of risk with hypertension (95% CIs) after adjusting for confounding factors were 0.63 (0.35, 1.12), 0.49 (0.28, 0.86), and 0.62 (0.35, 1.09) for those in Q2, Q3, and Q4, respectively. Restricted cubic spline functions were used and a U-shaped relationship between physical activity and hypertension risk was found, indicative of an optimal level of physical activity, which was found to be 112 METs-h/w. Our data suggest maintenance of optimal levels of total daily physical activity may be important for preventing hypertension in Chinese adults over the age of 40.

INTEGRATION OF SECURITY AND FAULT TOLERANCE IN SENSOR NETWORKS BASED ON THE ANALYSIS OF ENERGY CONSUMPTION AND TRAFFIC
Authors: Dovzhenko Nadiia , Ivanichenko Yevhen , Skladannyi Pavlo , Ausheva Nataliya
Published: September 2024

This article examines the functioning of sensor networks as a key component of the Internet of Things (IoT) technology, which facilitates integration between the physical and digital worlds. It analyzes the challenges sensor networks face, including limited resources, node failures, scalability, and security threats. The main components of sensor networks are discussed: sensors, smart elements, gateways, and communication modules that enable data collection and transmission for further analysis. Attention is drawn to the fact that sensor networks are often targets of malicious attacks, such as DDoS, Sinkhole, and routing attacks, which necessitate the development of new protection methods. The paper thoroughly examines threats from illegitimate elements in sensor networks that can disrupt network operations, cause data leaks, and affect network resilience and fault tolerance by exhausting resources. To effectively detect such nodes, it is proposed to apply mechanisms for traffic analysis, energy consumption monitoring, and encryption. The nature of failures in sensor networks and the interrelationship between fault tolerance and security are explored. Probabilities of failure for networks of different sizes are calculated, and mechanisms for improving fault tolerance, including node redundancy, self-healing algorithms, and fault tolerance mechanisms, are proposed. A methodology for detecting malicious nodes based on traffic and energy characteristics analysis is suggested. It was found that nodes exceeding threshold values for the number of transmitted packets or energy consumption may be malicious. It is noted that combining various methods will improve the accuracy of detecting malicious nodes at early stages, significantly enhancing the level of information security in sensor networks. Prospects for further research into the development of new protective mechanisms and improvements in the fault tolerance of sensor networks are highlighted.

Published: September 2024

MikroRNA'lar (miRNA'lar), gen anlatımının düzenlenmesinde etkin rol oynayan ~22 bp uzunluğunda küçük, kodlanmayan RNA dizileridir. Son yıllarda yapılan araştırmalarda inek sütünde bol miktarda miRNA bulunduğu tespit edilmiş ve inek sütü miRNA’larının gıda kalitesinde biyobelirteç olarak kullanım potansiyellerine yönelik bulgular elde edilmiştir. Ayrıca, güncel araştırmalar beslenme yoluyla inek sütü miRNA’larının insana transfer olarak önemli bir biyoaktif besin komponenti olabileceğini göstermektedir. Süt ve süt ürünlerinde üretim aşamalarında bozunmadan kalan inek sütü miRNA'larının insanların dolaşım sistemine geçerek farklı insan hastalıkları ile ilişkili önemli yolaklara etki edebileceği düşünülmektedir. Bu sebepten süt ve süt ürünlerinin miRNA içeriklerinin belirlenmesi önemlidir ve bu konuda güncel literatürde önemli bir boşluk olduğu gözlenmektedir. Bu çalışmada, literatürden insan homolog sekansına sahip ve inek sütünde bol miktarda bulunan miR-191’in kaynatma aşaması sonrası içme sütündeki miktarındaki değişiklik araştırılmıştır. Bu kapsamda süt örnekleri (çiğ süt ve pastörize süt) 100°C’de kaynatılarak örneklerden total RNA izolasyonu gerçekleştirilmiş ve elde edilen RNA’lardaki miR-191 miktarı RT-qPCR yöntemi ile analiz edilmiştir. Literatürde içme sütünün üretiminde kullanılan homojenizasyon ve pastörizasyon işlemlerinin miRNA spesifik farklı etkilere sebep olduğu gözlenmiştir. Gerçekleştirilen işlemler sonucunda literatüre uyumlu biçimde miR-191 miktarında kaynatılmış çiğ sütte %95.8 oranında (p<0.0001) ve kaynatılmış pastörize sütte %66.4 oranında (p=0.001) azalma gözlemlenmiştir. Bunun yanında çiğ süt ve pastörize sütte analiz edilen miR-191 için elde edilen CT değerleri arasında istatistiksel olarak anlamlı bir farklılık olduğu gözlenmiştir (p<0.0001). Çalışmamızın sonucu, sütün kaynatılmasının süt miRNA içeriği üzerindeki etkilerine ilişkin ön veriler ortaya koyarak işleme adımlarının süt miRNA bileşimi üzerine miRNA spesifik etkisinin olduğunu önemle vurgulamaktadır.

Authors: Şahin Demirel Ayça Nur , Erik Taner
Published: September 2024

This study examines the potential impact of climate change on small cattle livestock and milk productivity in Iğdır province. The study takes into account various factors, including the effects of climate change on animal stress levels, nutrient quality in grazing areas, and the spread of parasites or diseases, which may indirectly affect milk productivity. To evaluate this impact, the study utilizes eXtreme Gradient Boosting (XGBoost) machine learning models with five different climate variables, analyzing the small cattle data from Iğdır province between 2004 and 2023. Two machine learning models were created to investigate the effect of climate variables on milk yield in small cattle in Iğdır province, using a dataset of 10820 rows and 16 columns. The machine learning models revealed that five different climate variables had no significant effect on milk yield. This finding is important for the economic welfare of the region, as cattle farming plays a crucial role in the economy of Iğdır province. The neutral effect of climate change is therefore evaluated positively for Iğdır province. The study suggests that there has been no significant change in milk productivity over the last 20 years due to the constant percentage of sheep that produce milk. It is recommended that farmers in Iğdır province consider increasing the number of lactating sheep to enhance overall cattle milk production.

The objective of this study was to develop sustainable edible films based on seaweed mucilage (Chondrus crispus) containing pomegranate peel extract (PPE). For this purpose, films containing different concentrations of PPE (%0, 0.25, 0.50, and 1; w/v) were evaluated for their thickness, mechanical properties, color, opacity, antioxidant capacity, and total phenolic content (TPC). The incorporation of PPE significantly affected the values of elongation at break, color, antioxidant capacity, and TPC (p<0.05). However, the effect of PPE incorporation on the thickness, tensile strength, and opacity of the films was not significant (p>0.05). The addition of PPE significantly (p<0.05) increased the elasticity of the films, with the highest elongation at break observed in the film containing 0.5% PPE (126.90%). The DPPH scavenging activity of the films containing PPE ranged from 0.13 to 0.23 mmol TEAC/g, and the TPC values ranged from 8.39 to 29.95 mg GAE/g film. The antioxidant capacity and TPC values of the films increased significantly (p<0.05) with higher concentrations of PPE. The addition of PPE resulted in a decrease in film brightness, but an increase in redness and yellowness. In conclusion, the developed films offer a promising alternative for sustainable edible film production.
