Article Citation - WoS: 2Citation - Scopus: 2Electron-Lattice Interaction Scattering Mobility in Tl2ingase4< Single Crystals(Iop Publishing Ltd, 2008) Qasrawi, A. F.; Gasanly, N. M.In this work, the dark electrical resistivity, charge carrier density and Hall mobility of Tl(2)InGaSe(4) single crystal have been recorded and analyzed to investigate the dominant scattering mechanism in the crystal. The data analyses have shown that this crystal exhibits an extrinsic n-type conduction. The temperature-dependent dark electrical resistivity analysis reflected the existence of two energy levels as 0.396 and 0.512 eV, being dominant above and below 260 K, respectively. The temperature dependence of the carrier density was analyzed by using the single-donor-single-acceptor model. The latter analysis has shown that the above maintained 0.512 eV energy level is a donor impurity level. The compensation ratio for this crystal is determined as 0.96. The Hall mobility of Tl(2)InGaSe(4) is found to be limited by the scattering of electron-acoustic phonon interactions. The calculated theoretical acoustic phonon scattering mobility agrees with the experimental one under the condition that the acoustic deformation potential is 12.5 eV.Conference Object Embryo Spatial Model Reconstruction(Springer international Publishing Ag, 2020) Dirvanauskas, Darius; Maskeliunas, Rytis; Raudonis, Vidas; Misra, SanjayTime lapse microscopy offered new solutions to study embryo development process. It allows embryologist to monitor embryo growth in real time and evaluate them without interfering into their growth environment. Embryo evaluation during growth process is one of the key criteria in embryo selection for fertilization. Live embryo monitoring is time consuming and new tools are offered to automate part of process. Our proposed algorithm gives new possibilities for embryo monitoring. It uses embryo images which are taken from different embryo layers, extracts embryo cell features and returns metrical evaluation to compare different embryos. High number of extracted features shows embryo fragmentation. Other tool whichwe present is spatial embryo model. Features extracted from embryo layers are combined together to spatial model. It allows embryologist to examine embryo model and compare different layers in one space. The obtained spatial embryo model will be later used to develop new algorithms for embryo analysis tasks.Article Citation - WoS: 5Citation - Scopus: 6Mild Solutions for Conformable Fractional Order Functional Evolution Equations Via Meir-Keeler Type Fixed Point Theorem(Univ Nis, Fac Sci Math, 2025) Berrighi, Fatma; Medjadj, Imene; Karapinar, ErdalIn this study, we delve into the realm of mild solutions for conformable fractional order functional evolution equations, focusing on cases where the fractional order is strictly greater than 1 and less than 2 within a separable Banach space. We demonstrate the existence, uniqueness, attractivity, and controllability of these solutions under local conditions. Our approach involves leveraging a contribution of Meir-Keeler's fixed point theorem alongside the principle of measures of noncompactness. To demonstrate the practical ramifications of our theoretical finds, we provide a specific example that underscores the relevance and applications of the established results.Article Citation - WoS: 41Citation - Scopus: 52Discussion on Generalized-(αψ, Βφ)-Contractive Mappings Via Generalized Altering Distance Function and Related Fixed Point Theorems(Hindawi Ltd, 2014) Berzig, Maher; Karapinar, Erdal; Roldan-Lopez-de-Hierro, Antonio-FranciscoWe extend the notion of (alpha psi, beta phi)-contractive mapping, a very recent concept by Berzig and Karapinar. This allows us to consider contractive conditions that generalize a wide range of nonexpansive mappings in the setting of metric spaces provided with binary relations that are not necessarily neither partial orders nor preorders. Thus, using this kind of contractive mappings, we show some related fixed point theorems that improve some well known recent results and can be applied in a variety of contexts.Article Citation - WoS: 2Citation - Scopus: 19Periodic Points of Weaker Meir-Keeler Contractive Mappings on Generalized Quasimetric Spaces(Hindawi Publishing Corporation, 2014) Lin, Ing-Jer; Chen, Chi-Ming; Karapinar, ErdalBy using the weaker Meir-Keeler function phi and the triangular alpha-admissible mapping alpha, we introduce the notion of (alpha - phi)-weaker Meir-Keeler contractive mappings and prove a theorem which assures the existence of a periodic point for these mappings on generalized quasimetric spaces.Master Thesis Buchi Emecheta'nın İkinci Sınıf Vatandaş ve Andrea Levy'nin Küçük Ada Romanlarında Kadın Göçünün Postkolonyal İncelemesi(2024) Imran, Aimen; Aras, GökşenBu çalışma, Buchi Emecheta'nın Second Class Citizen ve Andrea Levy'nin Small Island romanlarını postkolonyal bir göç yaklaşımıyla incelemeyi amaçlamaktadır. Her iki kadın göçmen yazar, romanlarında anavatanlarından Britanya'ya göç eden kadın göçmen kahramanların deneyimlerini özel olarak kaleme alır. Çalışma, ırk ve cinsiyet nedeniyle iki kat marjinalleşmiş olan bu karakterlerin karşılaştıkları sorunları karşılaştırıp karşıtlıklarını inceleyecektir. Bu araştırmanın ana hedefleri, Arnold van Gennep'in üçlü teorisi ve Stuart Hall'un Kültürel Kimlik teorisi çerçevesinde kadın göçünün her iki romanda nasıl tasvir edildiğini incelemektir. Romanlardaki kadın göçmenlerin liminal deneyimlerini araştırmayı ve göçün cinsiyet boyutları ile kimlik müzakerelerini incelemeyi amaçlamaktadır. Bu çalışma, kadın göçmenlerin postkolonyal bağlamlardaki deneyimlerine ve bunların kültürel kimlik, liminalite ve postkolonyalizm söylemi içindeki önemine daha derin bir anlayış kazandırmayı hedeflemektedir. İki roman üzerine eleştirel araştırma makaleleri yazılmış olmasına rağmen, kadın göçü, liminalite ve kültürel kimlik açısından postkolonyal bir perspektifle birlikte incelenmemişlerdir; dolayısıyla bir araştırma boşluğu yaratmaktadır. Bu tez, romanın kadın karakterlerine liminalite üçlü aşamalarının uygulanmasına ve anavatanlarından Britanya'ya göç ederken nasıl varlık ve olma aşamalarından geçtiklerine odaklanacaktır.Conference Object Fcnc Decays of Spin-1/2 Double Heavy Baryons To Spin-3/2 Single Heavy Baryons(E D P Sciences, 2024) Aliev, Tahmasib; Askan, Emre; Ozpineci, Altug; Sarac, YaseminIn recent years, there have been many discoveries in the spectroscopy of hadrons containing heavy quarks. Almost all baryons containing a single heavy quark are discovered in experiments. The quark model predicts the existence of many baryons with double heavy quarks. Among the possible double heavy baryons, only Xi(+)(cc) and Xi(++)(cc) have been experimentally observed in LHCb. Flavor-changing neutral current (FCNC) processes represent a promising platform for precise testing of SM and looking for new physics beyond the SM. In this study, the weak decays of spin-1/2 double heavy baryons to spin3/2 single heavy baryons induced by FCNC are studied within the light cone QCD sum rules method. First, the transition form factors of Xi(0,-)(bb) -> Xi(*0,(l) over bar l)(b), Xi(0,-)(bb) -> Sigma(*0,(l) over bar l)(b), Omega(-)(bb) -> Sigma(b)*(-(l) over barl), Omega(-)(bb) -> Sigma(*0,(l) over bar l)(b) decays are calculated. Then, the corresponding decay widths are estimated using the results for the form factors.Article Citation - WoS: 18Citation - Scopus: 21Research Trends in Management Issues of Global Software Development: Evaluating the Past To Envision the Future(Taylor & Francis inc, 2011) Mishra, Deepti; Mishra, AlokThis paper presents research trends in management issues (project management, process management, knowledge management, requirements management, configuration management, risk management, quality management) of distributed/global information system development. The main objective is to highlight the current research and practice direction in these areas. The results are based on peer-reviewed conference papers/journal articles, published between 2000 and early 2011. The analysis revealed that most research has been done in project management, process management, knowledge management and requirements management areas while configuration, risk, and quality management issues could get only limited attention in global/distributed information system development. This indicates the need for future research (quantitative and qualitative) in these areas.Article Citation - WoS: 5Citation - Scopus: 5Electrochemical Polymerization of Para-Substituted Haloanilines(Taylor & Francis inc, 2006) Cihaner, A; Önal, AMPolyhaloanilines: poly(4-fluoroaniline) (P4FAN), poly(4-chloroaniline) (P4CAN), and poly(4-bromoaniline) (P4BAN), are synthesized from para-substituted haloaniline monomers; 4-fluoroaniline (4FAN), 4-chloroaniline (4CAN), and 4-bromoaniline (4BAN), respectively, via constant potential electrolysis (CPE) in acetonitrile-water mixture (1:1 v/v) with NaClO4 as supporting electrolyte. Prior to CPE, electrochemical behavior of the monomers were investigated in organic medium utilizing cyclic voltammetry (CV). The course of CPE was monitored using in-situ UV-VIS spectroscopic technique. Characterization of polymer products have been carried out using FT-IR and NMR spectroscopic techniques and thermal behaviors were studied using differential scanning calorimeter (DSC). Polyhaloanilines synthesized by electrochemical oxidation were doped using iodine and the change in the paramagnetic behavior was monitored by ESR, UV-VIS, and FT-IR.Conference Object A Model for Measuring Cognitive Complexity of Software(Springer Verlag, 2008) Misra,S.; Akman,I.This paper proposes a model for calculating cognitive complexity of a code.
