Öğe Türü: Yayın , Geometric Reconstruction of Ribbed Domes Covering the Ishrat-Khana Mausoleum in Samarkand(Elsevier Ltd., 2026) Akyürek, Muhammed Emin; Akyürek, Muhammed EminIshrat-Khana Mausoleum in Samarkand, a Timurid artifact, represents a significant example of the 15th century with its ribbed domes, opening a new era in the region's architecture. However, it was surveyed only once by hand drawing and has been standing in ruins due to its geometric complexity. Subsequent restoration attempts, on the other hand, contain serious faults. This study is about the geometric reconstruction of Ishrat-Khana's superstructure to contribute to possible restorations. The study offers one of the first comprehensive studies on ribbed domes in Transoxania, filling a significant gap in the literature. The geometry of the ribbed domes has been analyzed according to some design parameters inspired by historical drawings. The analyses revealed that restorations in the central hall and the masjid contain methodical errors, while the restitution drawings are also incorrect for the southern hall and the basement. As a result, a specific formulation for drawing a potential comprehensive restoration has been proposed.Öğe Türü: Yayın , Search for a New Scalar Resonance Decaying to a Higgs Boson and Another New Scalar Particle in the Final State With Two Bottom Quarks and Two Photons in Proton-Proton Collisions at TeV(Springer, 2025) Hayrapetyan, Aram A.; Makarenko, V.; Tumasyan, A. R.; Atakişi, İsmail Okan; Atakişi, İsmail OkanThis article has 2,408 authors. A search is presented for a new scalar resonance, X, decaying to a standard model Higgs boson and another new scalar particle, Y, in the final state where the Higgs boson decays to a pair, while the Y particle decays to a pair of photons. The search is performed in the mass range 240–1000 GeV for the resonance X, and in the mass range 70–800 GeV for the particle Y, using proton-proton collision data collected by the CMS experiment at TeV, corresponding to an integrated luminosity of 132 fb−1. In general, the data are found to be compatible with the standard model expectation. Observed (expected) upper limits at 95% confidence level on the product of the production cross section and the relevant branching fraction are extracted for the X → YH process, and are found to be within the range of 0.05–2.69 (0.08–1.94) fb, depending on mX and mY. The most significant deviation from the background-only hypothesis is observed for X and Y masses of 300 and 77 GeV, respectively, with a local (global) significance of 3.33 (0.65) standard deviations.Öğe Türü: Yayın , Hemodiyaliz Kateter Kullanımında Kılavuz Önerileri(Turk Nefroloji Diyaliz ve Transplantasyon Hemsireleri Dernegi, 2025) Özer, Zülfünaz; Özer, ZülfünazHemodiyaliz, son dönem böbrek yetmezliği olan hastalarda yaşamısürdürmek için gerekli temel renal replasman tedavilerinden biridir.Tedavinin başarısı, uygun vasküler erişim yolunun seçimi ve etkinyönetimi ile doğrudan ilişkilidir. Vasküler erişim, hemodiyalizinyaşam çizgisi olarak kabul edilmekte olup, arteriyovenöz fistül vegreft kalıcı erişim yolları olarak öncelikli önerilirken, santral venözkateterler acil durumlarda, geçici gereksinimlerde veya kalıcı girişimuygun değilse tercih edilmektedir. Bununla birlikte, santral venözkateter kullanımının enfeksiyon, tromboz, tıkanıklık, bakteriyemi vedamar duvarı hasarı gibi komplikasyon oranlarının yüksek olmasınedeniyle, uluslararası kılavuzlar kateter kullanımının azaltılmasını,arteriyovenöz fistül erişim oranlarının artırılmasını ve kronikkullanımın %10’un altında tutulmasını önermektedir. 2019 KidneyDisease Outcomes Quality Initiative güncellemesi ile “Önce Fistül”yaklaşımı, hastanın klinik, sosyal ve yaşam hedeflerini önceleyen “SonDönem Böbrek Yetmezliği Yaşam Planı” modeline evrilmiştir. Buyaklaşım, hastaya özgü tedavi planlamasının önemini vurgulamakta;erişim yolunun seçiminde damar yapısı, yaşam beklentisi, eşlik eden hastalıklar ve tedavi tercihlerini temel almaktadır. Santralvenöz kateter bakımında asepsi-antisepsi uygulamaları, el hijyeni,düzenli pansuman, lümen yıkama, heparinle kilitleme tekniklerineuyum ve her seans öncesi komplikasyon değerlendirmesi kritikgerekliliklerdir. Hemşirelik bakımı santral venöz kateter yönetimindebelirleyici role sahip olup, hasta ve yakınlarının eğitimi enfeksiyonve diğer komplikasyonların azaltılmasında tamamlayıcı etkidedir.Multidisipliner yaklaşımın güçlendirilmesi, erken sevk uygulamalarıve bakım protokollerine bağlılığın artırılması; hasta güvenliği, yaşamkalitesi ve sağkalım oranları üzerinde olumlu sonuçlar doğurmaktadır.Bu çalışma, güncel kılavuzlar (Kidney Disease Outcomes QualityInitiative ve Dünta Sağlık Örgütü) kılavuzlarına doğrultusundahemodiyaliz kateter kullanımına ilişkin hemşirelik bakım ilkeleriniözetleyen bir derlemedir.Öğe Türü: Yayın , The Digital Orchard: Advanced Data-Driven Technologies in Apple Breeding and Genetic Modification(Frontiers Media SA, 2026) Abid, Fazeel; Zhang, Zhao; Farooque, Ghulam; Zulqarnain, Rana Muhammad; Rasheed, Jawad; Osman, Onur; Alsubai, Shtwai; Menzli, Leila Jamel; Rasheed, JawadThe apple (Malus × domestica), a globally significant perennial fruit crop, facesimmense pressure from climate change, evolving pathogens, and consumerdemand for novel traits. Also, remains constrained by slow trait selection despitetechnological advances. Further, the traditional breeding methods are slow andresource-intensive, hampered by the apple’s long juvenile period and highheterozygosity. This systematic literature review (SLR) synthesizes the state ofthe art in advanced data-driven technologies for accelerating apple breeding andgenetic modification. Following the PRISMA-EcoEvo protocol, 47 selectedstudies were analyzed from databases including Web of Science, Scopus, andPubMed. Our thematic synthesis reveals a paradigm shift towards a“digitalbreeding”model, characterized by the convergence of three coretechnological pillars. First, high-throughput phenotyping (HTP), whichleverages sensor modalities such as RGB-D, hyperspectral imaging, and LiDAR,is automating the collection of trait data at an unprecedented scale. Second,machine learning (ML) and deep learning (DL) algorithms are being deployed fordiverse applications, including cultivar identification with over 96% accuracy,non-destructive quality prediction, and genomic selection, thereby boostingpredictive ability for key traits by up to 18%. Third, precise and efficientgenome editing, predominantly using Clustered Regularly Interspaced ShortPalindromic Repeats (CRISPR)/CRISPR-associated protein 9 (Cas9), is enablingthe rapid introduction of desirable traits, such as disease resistance, enhancedshelf life, and improved nutrient uptake. Demonstrated transgene-free editingprotocols are accelerating the path to commercialization. We further explore theintegration of these pillars through the agricultural internet of things (AIoT) anddiscuss emerging frontiers, including federated learning for data privacy,explainable AI (XAI) for model transparency, and the implications of recentregulatory frameworks. This review identifies critical research gaps, including the need for standardized open-access datasets and integrated end-to-endsystem validation. It concludes that the synergistic application of thesetechnologies is poised to revolutionize the speed, precision, and resilience ofapple improvement programs worldwide.Öğe Türü: Yayın , The Procyclicality of Credit Cycle of Islamic and Conventional Banks During COVID-19: Measuring Amplitude and Frequency Indicators(Sciendo, 2026) Muttaqin, Ecky Imamul; Uluyol, Burhan; Uluyol, BurhanProcyclicality in the banking sector is one of the important indicators that may encourage the systemic risk in the banking sys-tem. This study examines banking behavior of the economy during the COVID-19 pandemic and analyze the amplitude and frequency of the credit cycle of Islamic and conventional banks. This study is primarily focused on the credit property of Islamic and conventional banks from 2014 to 2020 with application of Ordinary Least Square (OLS), Frequency Base Filter Analysis (FBF) and Turning Point Analysis. Our study finds that the size of Islamic bank’s amplitude is larger than the size of conventional bank’s amplitude. This is char-acteristic of Islamic banks based on the pattern of financing of the real sector. Meanwhile, conventional banks encourage the creation of bubble capital because it is related to the credit pattern grounded in speculative activities based on the interest system. Therefore, con-ventional banks need to encourage credit patterns based on capital. Meanwhile, the size of the frequency of Islamic banks has a longer frequency measure than conventional banks, but the number of cy-cles formed is the same as a perfect cycle.
