Yayın Prisoners’ dilemma in a spatially separated system based on spin–photon interactions(MDPI, 2022-09) Altıntaş, Azmi Ali; Özaydın, Fatih; Bayındır, Cihan; Bayrakçı, VeyselHaving access to ideal quantum mechanical resources, the prisoners’ dilemma can be ceased. Here, we propose a distributed quantum circuit to allow spatially separated prisoners to play the prisoners’ dilemma game. Decomposing the circuit into controlled-Z and single-qubit gates only, we design a corresponding spin–photon-interaction-based physical setup within the reach of current technology. In our setup, spins are considered to be the players’ logical qubits, which can be realized via nitrogen-vacancy centers in diamond or quantum dots coupled to optical cavities, and the game is played via a flying photon realizing logic operations by interacting with the spatially separated optical cavities to which the spin qubits are coupled. We also analyze the effect of the imperfect realization of two-qubit gates on the game, and discuss the revival of the dilemma and the emergence of new Nash equilibria.Yayın Microservices-based databank for Turkish hazelnut cultivars using IoT and semantic web technologies(John Wiley and Sons Ltd, 2024-03-30) Aydın, Şahin; Aldara, DieaaInformation and communication technologies (ICTs) can play a crucial role in facilitating access to comprehensive information on the quality standards of Turkish hazelnut cultivars. In this regard, this study introduces a Hazelnut Databank System (HDS) that utilizes the microservices architecture, an integrated software system supported by the Internet of Things (IoT) and semantic web, to categorize Turkish hazelnut cultivars. The study focuses on developing microservices using various programming languages and frameworks. Specifically, C# on the.NET Core Framework was used for both microservices and the web-based application implemented through the ASP.NET Core MVC Framework. Mobile-based software applications were created using Xamarin. Forms, and the IoT application was developed using the Python programming language. The data storage is facilitated through the MS SQL Server database. Additionally, the study incorporates the implementation of a hazelnut species classification system using the DNN + ResNet50 machine learning model, achieving an impressive accuracy rate of 95.77%. The overall usability of the system was evaluated, resulting in a score of 42 out of 50. By providing detailed information on Turkish hazelnut cultivars, the HDS has the potential to greatly improve hazelnut production quality in Turkey and increase awareness of hazelnut agriculture among relevant stakeholders.Yayın Son ergenlik döneminde dissosiyatif bulgular ile ruminasyon arasındaki ilişkide duyguları ifade etmenin rolü(Kıbrıs Ruh Sağlığı Enstitüsü, 2023-03-27) Özgönül, Afranur; Aktan, Zekeriya Deniz; Ülkümen, İpekBu araştırmanın temel amacı son ergenlik dönemindeki bireylerin dissosiyatif bulguları ile ruminasyon düzeyleri arasındaki ilişkide duyguları ifade etmenin aracı rolünü incelemektir. Araştırmaya 18-24 yasları arasında olan 502 kişi katılmıştır. Veriler, Sosyodemografik Bilgi Formu, Dissosiyasyon Ölçeği (DIS-Q), Ruminatif Düşünce Biçimi Ölçeği (RDBÖ) ve Duyguları İfade Etme Ölçeği (DİEÖ) aracılığıyla toplanmıştır. Araştırmadan elde edilen bulgulara göre son ergenlik dönemindeki bireylerin ruminasyon düzeyleri arttıkça duyguları ifade etme düzeylerinin azaldığı ve dissosiyasyon düzeylerinin arttığı; duyguları ifade etme düzeyleri azaldıkça dissosiyasyon düzeylerinin arttığı görülmüştür. Son ergenlik dönemindeki bireylerin dissosiyatif bulguları ile ruminasyon düzeyleri arasındaki ilişkide duyguları ifade etmenin kısmi aracı etkisi olduğu saptanmıştır. Araştırmamızın söz konusu değişkenlerin geçmiş araştırmalarda sınırlı sayıda incelenmesi açısından literatüre katkı sağladığı düşünülmektedir.Yayın Engineering four-qubit fuel states for protecting quantum thermalization machine from decoherence(Multidisciplinary Digital Publishing Institute (MDPI), 2024-01-10) Özaydın, Fatih; Sarkar, Ramita; Bayrakçı, Veysel; Bayındır, Cihan; Altıntaş, Azmi Ali; Müstecaplıoğlu, Özgür E.Decoherence is a major issue in quantum information processing, degrading the performance of tasks or even precluding them. Quantum error-correcting codes, creating decoherence-free subspaces, and the quantum Zeno effect are among the major means for protecting quantum systems from decoherence. Increasing the number of qubits of a quantum system to be utilized in a quantum information task as a resource expands the quantum state space. This creates the opportunity to engineer the quantum state of the system in a way that improves the performance of the task and even to protect the system against decoherence. Here, we consider a quantum thermalization machine and four-qubit atomic states as its resource. Taking into account the realistic conditions such as cavity loss and atomic decoherence due to ambient temperature, we design a quantum state for the atomic resource as a classical mixture of Dicke and W states. We show that using the mixture probability as the control parameter, the negative effects of the inevitable decoherence on the machine performance almost vanish. Our work paves the way for optimizing resource systems consisting of a higher number of atoms.Yayın Alevi ve Bektaşi yazı-resim sanatında insan sureti(Ankara Haci Bayram Veli University, 2020-03-20) Günana, MeryemBu makalede; 1826’da dağıtılan Bektaşi tarikatı Babagan (Mücerret) kolunun üretmiş olduğu, ancak 1925 yılında tekke ve zaviyelerin kapatılmasıyla özel koleksiyonlara, müzelere girmiş fakat çoğunluğu ise tahrip edilmiş olan; sureti sîrete, sîreti surete dönüştüren “yazı-resim” sanatının Alevi ve Bektaşi erkânındaki yeri ve önemi anlatılmaya çalışılmıştır. Bu sanatın Hurûfîlik etkisiyle ortaya çıkmadığı, piktogram veya güzel yazı yazma/kaligrafi olmadığı; vahdet-i vücut düşüncesinin bir tezahürü olduğu ifade edilmiştir. Alevi ve Bektaşi erkânının ortaya koyduğu yazı-resim sanatının harflerle üretilmiş bulunması Hurufîlik olarak adlandırılmasına neden olsa da; bu sanatın Hurufîlik düşüncesinin ürünü değil aksine vahdet-i vücut düşüncesinin bir yansıması olduğuna dair açıklık getirilmiştir. Simetrik bir anlayışla gerçekleştirilen yazı-resimlerde, hat sanatında “müsennâ” yani “aynalı yazı” olarak bilinen yazı şeklinin neden tercih edildiği anlatılmaya çalışılmıştır. Varlığın zahir(dış) ve batın(iç) suretlerine simgesel bir göndermede bulunan yazı-resim sanatının vahdet-i vücut düşüncesi ile olan irtibatı anlatılmıştır. Yazı-resimlerde önemli bir yere sahip olan insan suretinde yapılmış eserlerin plastik değerleri ve bu eserler üzerinden, Alevi ve Bektaşi erkânında insan olmak, insan suretinin sîrete nasıl dönüştürüldüğü; insan suretinde yazılan “Allah-Muhammed-Ali” isimlerinin görünmeyenden nasıl görünür kılındığı anlatılmaya çalışılmıştır. Meleklerin Âdem’e secde ettikleri andan bugüne niçin İnsan’a secde edildiğine ve bunun Alevi ve Bektaşi erkânında taşıdığı anlamlara dair bilgi verilmiştir.Yayın Evaluation of post-swallow residue with visual analysis of swallowing efficiency and safety in patients with idiopathic Parkinson's disease(Sage Publications Inc, 2023-12) Doruk, Can; Çaytemel, Berkay; Şahin, Erdi; Kara, Hakan; Samancı, Bedia; Abay, Sevinç Nisa; Bilgiç, Başar; Hanağası, Haşmet; Başaran, Bora; Enver, Necati; Rameau, AnaisObjectives: Dysphagia is common in idiopathic Parkinson's disease (IPD) and is associated with impairments in both swallowing safety and swallowing efficiency. The goals of this study were to define post-swallow residue patterns in people with IPD and describe pathophysiological endoscopic findings affecting residue accumulation. Methods: This was a prospective single-blinded cross-sectional cohort study of patients with the diagnosis of IPD recruited from a Movement Disorder Clinic. Clinical variables included patient age, cognitive function, and measures of disease severity, and laryngoscopic examinations with a flexible endoscopic evaluation of swallowing (FEES) were completed for each patient. Visual Analysis of Swallowing Efficiency and Safety (VASES) was used to analyze FEES. Post-swallow residue outcomes and non-residue endoscopic outcomes including the Bowing index, Penetration Aspiration Scale (PAS) score, premature leakage, and build-up phenomenon were evaluated. Multiple regression models were used to evaluate factors affecting the residue at different anatomic levels. Results: Overall 53 patients completed the study. The multiple regression analyses showed a relation between (1) the presence of residue at the level of oropharynx and epiglottis with premature leakage, (2) the presence of residue at the level of the laryngeal vestibule and vocal folds with build-up phenomenon, and (3) the presence of residue at the level of the hypopharynx, laryngeal vestibule, and subglottis with airway invasion. Conclusion: Residue pattern during FEES is associated with specific swallow dysfunctions in IPD. Using residue localization and quantification may be a helpful tool in assessing the impact of targeted swallowing interventions in patients with IPD and dysphagia.Yayın Quantum Zeno repeaters(Nature Research, 2022-09-12) Bayrakçı, Veysel; Özaydın, FatihQuantum repeaters pave the way for long-distance quantum communications and quantum Internet, and the idea of quantum repeaters is based on entanglement swapping which requires the implementation of controlled quantum gates. Frequently measuring a quantum system affects its dynamics which is known as the quantum Zeno effect (QZE). Beyond slowing down its evolution, QZE can be used to control the dynamics of a quantum system by introducing a carefully designed set of operations between measurements. Here, we propose an entanglement swapping protocol based on QZE, which achieves almost unit fidelity. Implementation of our protocol requires only simple frequent threshold measurements and single particle rotations. We extend the proposed entanglement swapping protocol to a series of repeater stations for constructing quantum Zeno repeaters which also achieve almost unit fidelity regardless of the number of repeaters. Requiring no controlled gates, our proposal reduces the quantum circuit complexity of quantum repeaters. Our work has potential to contribute to long distance quantum communications and quantum computing via quantum Zeno effect.Yayın Superactivating bound entanglement in quantum networks via quantum Zeno dynamics and a novel algorithm for optimized Zeno evolution(MDPI, 2023-01) Özaydın, Fatih; Bayrakçı, Veysel; Altıntaş, Azmi Ali; Bayındır, CihanAn arbitrary amount of entanglement shared among nodes of a quantum network might be nondistillable if the nodes lack the information on the entangled Bell pairs they share. Making such a system distillable, which is called the superactivation of bound entanglement (BE), was shown to be possible through systematic quantum teleportation between the nodes, requiring the implementation of controlled-gates scaling with the number of nodes. In this work, we show in two scenarios that the superactivation of BE is possible if nodes implement the proposed local quantum Zeno strategies based on only single qubit rotations and simple threshold measurements. In the first scenario we consider, we obtain a two-qubit distillable entanglement system as in the original superactivation proposal. In the second scenario, we show that superactivation can be achieved among the entire network of eight qubits in five nodes. In addition to obtaining all-particle distillable entanglement, the overall entanglement of the system in terms of the sum of bipartite cuts is increased. We also design a general algorithm with variable greediness for optimizing the QZD evolution tasks. Implementing our algorithm for the second scenario, we show that a significant improvement can be obtained by driving the initial BE system into a maximally entangled state. We believe our work contributes to quantum technologies from both practical and fundamental perspectives bridging nonlocality, bound entanglement and the quantum Zeno dynamics among a quantum network.Yayın Associations among adolescents' mindfulness, sympathy, cognitive empathy, and sibling relationships(Sage Publication, 2024-02) Barata, Özge; Acar, İbrahim Hakkı; Bostancı, SelenIn the current study, we examined the direct and indirect paths from mindfulness to adolescents’ sibling relationships through their cognitive empathy and sympathy. The sample consisted of 220 adolescents (50.9 % female) between age of 13 and 17 years (M = 15.86, SD = 0.91). Participants reported their mindfulness (acceptance and awareness), cognitive empathy and sympathy, and sibling relationships. The parallel mediation model revealed that mindful awareness and acceptance predicted kindness, involvement, and empathy within sibling relationships through sympathy. In addition, there was a significant indirect effect of mindful awareness to empathy in sibling relationships through cognitive empathy. Findings provided information regarding the importance of indirect contributions of mindfulness to sibling relationships through cognitive empathy and sympathy.Yayın Analysis of the benefits, challenges and risks for the integrated use of BIM, RFID and WSN: a mixed method research(Emerald Group Publishing Ltd, 2023-07-11) Seyis, Senem; Sönmez, Alperen MertPurpose The purpose of this study is to identify, classify and prioritize the benefits, challenges and risks for the integrated use of building information modeling (BIM), radio frequency identification (RFID) and wireless sensor network (WSN) in the architecture, engineering, construction and operation (AECO) industry. Design/methodology/approach This study relies on the mixed method approach which consists of systematic literature review, semistructured interviews and Delphi technique. A systematic literature review was performed and face-to-face semistructured interviews with seven subject matter experts (SMEs) were conducted for identification and classification purposes. Delphi method was applied in two structured rounds with eleven SMEs for prioritization purpose. These three research techniques were chosen to reach the most accurate data by combining different perspectives on the subject matter. Data gathered by these three methods was triangulated to increase the validity and reliability of this research. Findings Thirteen benefits, ten challenges and four risks for the integrated use of BIM, RFID and WSN were identified. The results could aid the practitioners and researchers comprehend the pros and cons of this integration by representing SMEs' valuable insights and perspectives about the current and future status, trends, limitations and requirements of the AECO industry. The identified risks and challenges show the requirements for future studies while the benefits demonstrate the capabilities and the potential contributions of this hybrid integration to the AECO industry. Originality/value The integration of BIM, RFID and WSN is still not commonly implemented in the AECO industry. Some studies focused on this topic; however, none of them reveals the benefits, risks and challenges for integrating BIM, RFID and WSN in a holistic manner. This research makes a significant contribution to the AECO literature and industry by uncovering the benefits, challenges and risks for the integrated use of BIM, RFID and WSN that could increase industry applications.
