5403 Sayılı Kanun Çerçevesinde Terekedeki Tarım Arazilerinin Devredilmesi Karşısında Muris Muvazaası
(Istanbul Univ, 2020) Senol, A. Nilay; Kazmacı, Özge Uzun
The Law on Protection of Soil and Land Use, numbered 5403, aims to protect the unity of agricultural lands, and to prevent the division of the soil with inheritance. This law stipulates first, the possibility regarding the giving over of the agricultural land in succession to one or more heirs, to a family partnership, to a limited liability company or to a third person with the consensus of the heirs and second, in case of disagreement, the judge shall decide whether to leave the agricultural land to a competent heir or to sell the land. Furthermore, according to this law, the competent heir to whom the agricultural land will be left can be determined by means of testamentary disposition. It is possible and also valid within the legal constraints that the testator can also transfer the agricultural land to one of the heirs while he is alive. It is arguable whether this transaction can be considered as the testator’s simulation or not, if this transaction has also been made with a simulated transaction. Some principles are set out by the Supreme Court in terms of the simulation of the testator, and although these principles and decisions are criticized by the doctrine, such cases are held by these principles. The purpose and the regulations of the Law numbered 5403 shall be taken into consideration in determining testator’s simulation

Accurate Refinement of Docked Protein Complexes Using Evolutionary Information and Deep Learning
(Imperıal College Press, 2016) Akbal-Delibas, Bahar; Farhoodi, Roshanak; Pomplun, Marc; Haspel, Nurit
One of the major challenges for protein docking methods is to accurately discriminate native-like structures from false positives. Docking methods are often inaccurate and the results have to be refined and re-ranked to obtain native-like complexes and remove outliers. In a previous work we introduced AccuRefiner a machine learning based tool for refining protein-protein complexes. Given a docked complex the refinement tool produces a small set of refined versions of the input complex with lower root-mean-square-deviation (RMSD) of atomic positions with respect to the native structure. The method employs a unique ranking tool that accurately predicts the RMSD of docked complexes with respect to the native structure. In this work we use a deep learning network with a similar set of features and five layers. We show that a properly trained deep learning network can accurately predict the RMSD of a docked complex with 1.40 angstrom error margin on average by approximating the complex relationship between a wide set of scoring function terms and the RMSD of a docked structure. The network was trained on 35000 unbound docking complexes generated by RosettaDock. We tested our method on 25 different putative docked complexes produced also by RosettaDock for five proteins that were not included in the training data. The results demonstrate that the high accuracy of the ranking tool enables AccuRefiner to consistently choose the refinement candidates with lower RMSD values compared to the coarsely docked input structures.

Agent-Based Optimization To Estimate Nash Equilibrium in Power Markets
(Taylor & Francis Inc, 2013) Yücekaya, Ahmet; Valenzuela, Jorge
In most deregulated power markets firms bid daily into a day-ahead power market. The auction mechanism supply and demand determine the equilibrium at each hour. In this environment firms aim to maximize their revenues by carefully determining their bids. This requires the development of effective computational methods that help them estimate their competitors' behaviors under incomplete information. In this article an agent-based method that uses particle swarm optimization is described to simulate the behavior of market participants. Particle swarm optimization is used in the bidding process and an agent-based model is applied to find a Nash equilibrium. Different stopping conditions are used to determine the equilibrium. Experimental results are presented for two power systems.

A Bayesian Approach To Developing a Strategic Early Warning System for the French Milk Market
(Halmstad University, 2017) Bisson, Christophe; Gürpınar, Furkan
A new approach is provided in our paper for creating a strategic early warning system allowing the estimation of the future state of the milk market as scenarios. This is in line with the recent call from the EU commission for tools that help to better address such a highly volatile market. We applied different multivariate time series regression and Bayesian networks on a pre-determined map of relations between macro-economic indicators. The evaluation of our findings with root mean square error (RMSE) performance score enhances the robustness of the prediction model constructed. Our model could be used by competitive intelligence teams to obtain sharper scenarios, leading companies and public organisations to better anticipate market changes and make more robust decisions.

Bayesian Compressive Sensing for Primary User Detection
(Inst Engineering Technology-IET, 2016) Başaran, Mehmet; Erküçük, Serhat; Cirpan, Hakan Ali
In compressive sensing (CS)-based spectrum sensing literature most studies consider accurate reconstruction of the primary user signal rather than detection of the signal. Furthermore possible absence of the signal is not taken into account while evaluating the spectrum sensing performance. In this study Bayesian CS is studied in detail for primary user detection. In addition to assessing the signal reconstruction performance and comparing it with the conventional basis pursuit approach and the corresponding lower bounds signal detection performance is also considered both analytically and through simulation studies. In the absence of a primary user signal the trade-off between probabilities of detection and false alarm is studied as it is equally important to determine the performance of a CS approach when there is no active primary user. To reduce the computation time and yet achieve a similar detection performance finally the effect of number of iterations is studied for various systems parameters including signal-to-noise-ratio compression ratio mean value of accumulated energy and threshold values. The presented framework in this study is important in the overall implementation of CS-based approaches for primary user detection in practical realisations such as LTE downlink OFDMA as it considers both signal reconstruction and detection.

Beliefs of Living Donors About Recipients' End-Stage Liver Failure and Surgery for Organ Donation
(Elsevier Science Inc, 2017) Krespi-Boothby, Margörit Rita; Tankurt, A.; Acarli, Koray; Kanmaz, Turan; Yankol, Yucel; Kalayoğlu, Murat
Background. The concept of beliefs could provide a basis for how donors may perceive recipients' end-stage liver failure (ESLF) and surgery for organ donation. However there is no such quantitative study. Therefore the objective of this study was to explore beliefs of living donors about recipients' ESLF and surgery for organ donation. Methods. The sample comprised 16 living donors who donated a part of their liver to a patient who had ESLF. The data were analyzed by following established procedures for inductive qualitative analysis. Results. Analysis showed that donors' beliefs can be viewed in a number of groups. Beliefs about recipients' ESLF included diverse explanations for ESLF (blaming oneself and physicians) and physical symptoms (developmental slowing down). Beliefs about being a donor included reasons for being a donor (performing a good deed being healed) barriers to being a donor (other people being ignorant and selfish) ways to manage these barriers (following one's gut feeling) and factors facilitating being a donor (the feeling that one does not have many people to leave behind). Beliefs about surgery for organ donation included physical effects (pain feeling stiff). Beliefs about organ donation included views that general organ donation should be encouraged and that people's awareness should be raised. Conclusions. Existing psychological perspectives could help to interpret some beliefs. Nevertheless other beliefs not previously reported could be considered as targets for individual consultations/psycho-educational programs for fostering emotional well-being.

Between Anchors and Aspirations: a New Family of Bargaining Solutions
(Springer, 2019) Karagözoğlu, Emin; Keskin, Kerim; Özcan-Tok, Elif
We study the salience and power of reference points in determining the effective anchors and aspirations in bargaining problems. Along this line we enrich the analysis of the standard bargaining model with two new parameters: the first parameter can be interpreted as the effectiveness (or salience) of the reference point in determining the anchor whereas the second parameter can be interpreted as its effectiveness in shaping agents' aspirations. Utilizing these parameters we provide a unifying framework for the study of bargaining problems with a reference point. The two-parameter family of bargaining solutions we obtain encompasses some well-known solutions as special cases. We offer multiple characterizations for each individual member of this family as well as two characterizations for the whole solution family in bilateral bargaining problems.

Broadband Equalizer Design With Commensurate Transmission Lines Via Reflectance Modeling
(IEICE-INST ELECTRONICS INFORMATION COMMUNICATIONS ENG, 2008) Şengül, Metin Y.; Yarman, Sıddık Binboğa
In this paper an alternative approach is presented to design equalizers (or matching networks) with commensurate (or equal length) transmission lines. The new method automatically yields the matching network topology with characteristic impedances of the commensurate lines. In the implementation process of the new technique first the driving point impedance data of the matching network is generated by tracing a pre-selected transducer power gain shape without optimization. Then it is modelled its it realizable bounded-real input reflection coefficient in Richard domain which ill turn yields the desired equalizer topology with line characteristic impedances. This process results in an excellent initial design for the commercially available computer aided design (CAD) packages to generate final circuit layout for fabrication. An example is given to illustrate the utilization of the new method. It is expected that the proposed design technique is employed as it front-end to commercially available computer aided design (CAD) packages which generate the actual equalizer circuit layout with physical dimensions for mass production.

Broadband Microwave Amplifier Design With Lumped Elements
(Walter De Gruyter Gmbh, 2016) Şengül, Metin Y.
This study introduces a broadband microwave amplifier design that utilizes the measured scattering parameters of active devices without assuming an initial topology for the matching networks or an analytic form of the system transfer function. The algorithm can be extended to design multistage broadband microwave amplifiers. An example is given to illustrate the application of the proposed method. It was found that the proposed method provides very good initials for CAD tools to further improve amplifier performance by working on the element values.

Changing Naval Balances in the Eastern Mediterranean: Implications for Turkey
(Turkish Policy Quarterly, 2016) Güvenç, Serhat; Egeli, Sıtkı
This paper is aimed at providing an assesement of the growing Russian naval strength and assertiveness in the Eastern Mediterranean and its implications for Turkey's place in the regional naval power hierarchy after Moscow's direct involvement in the Syrian conflict in 2015. Although the main focus is on the Eastern Mediterranean the region obviously cannot be decoupled from the Black Sea and to some extent from the Aegean. Therefore this paper argues that the naval power hierarchy in these three regions have both historically influenced and been influenced by developments in others.
Changing Practices in International Broadcasting the Bbc World Service Example
(Ankara Üniversitesi İletişim Fakültesi, 2014) Yanardağoğlu, Eylem
Looking at the history of international broadcasting, one can observe that governments utilised international media as an element of public diplomacy as early as 1930s. Some of the first examples are seen at the BBC (British Broadcasting Corporation) World Service, which runs a Turkish Service since 1939. This research examines the factors that impact on international broadcasting and takes the BBC World Service as an example. It focuses on its Turkish Section in order to consider the changing practices at its language services and explore the influence of the issues such as public diplomacy, technological advances and economic policies on these language services. The BBC World Service and the Turkish section are chosen because they constitute one of the first examples of international broadcasting efforts. The findings are based on data that were collected via in-depth interviews conducted with editors and producers in 2011 at the World Service Central Newsroom and the Turkish Service. This research was funded by TÜBİTAK (the Scientific and Research Council of Turkey) post-doctoral study abroad bursary, at the Communication and Media Research Institute, University of Westminster in London, where the researcher was based as a visiting scholar.

Characterization of Mps Capped Cds Quantum Dots and Formation Self-Assembled Quantum Dots Thin Films on a Glass Substrate
(Natl Inst R&D Materials Physics, 2011) Koç, Kenan; Tepehan, Fatma Zehra; Tepehan, Galip Gültekin
Colloidal powdered and thin film forms of MPS capped CdS quantum dots have been produced by combination of colloidal chemistry and sol-gel method. Nanoparticles were self-assembled directly on a glass substrate using spin coating method without introducing any matrix. Colloidal powdered and thin film forms were characterised by absorbance photolimunescence XRD FT-IR HRTEM and AFM measurements. The HRTEM images give a grain size of 2.5-3.0 nm and this is in agreement with the values found in the absorbance and XRD measurement. Average size of the quantum dots increase with increasing of heat treatment temperature due to Oswald ripening.

A Combined Fuzzy Ahp-Goal Programming Approach To Assembly-Line Selection
(IOS Press, 2007) Ayağ, Zeki; Özdemir, Rıfat Gürcan
In mass production assembly-line balancing (ALB) problem has been a critical and repetitive issue for companies for long time. On the other hand equipment selection for stations has also been another important problem at the design stage of an assembly-line system. In this paper both problems are handled simultaneously. Therefore first goal programming (GP) method a well-suited technique is used to develop a preemptive formulation to joint both of the problems when the nature of the problem consists of several conflicting objectives and some mathematical constraints on solutions. Second an AHP method based on fuzzy scales which is incorporated with the GP is also used due to the fact that it takes both qualitative and quantitative judgments of decision-maker(s) into consideration to rank the equipment alternatives for stations by weight. The fuzzy AHP as one of the most commonly used multiple-criteria decision making (MCDM) methods has been effectively used for more than decade in both academic research and practice and takes the vagueness and uncertainty on judgments of decision-maker(s) into consideration due to the fact that the crisp pairwise comparison in the conventional AHP seems to insufficient and imprecise to capture the right judgments of decision-maker(s). In short in this study a combined fuzzy AHP-GP approach is proposed to evaluating assembly-line design alternatives with equipment selection. An integer GP formulation is constructed which also uses the fuzzy AHP scores of equipment alternatives and employs them as one of the goals. Then the mathematical model is solved to find out the ultimate alternative in terms of the minimized equipment cost and the maximized preference measures of decision-maker(s). The proposed approach is also illustrated on a sample case study.

Comparison of Earliest and Later Autobiographical Memories in Young and Middle-Aged Adults
(Istanbul Univ, 2019) Ece, Berivan; Demiray, Burcu; Öner, Sezin; Gülgöz, Sami
The current study examined earliest memories of young and middle-aged adults in comparison to a recent autobiographical memory and a free-report one from any life phase. These three types of memories were compared in terms of their memory characteristics such as vividness, emotionality. importance, confidence, and rehearsal frequency. A total of 319 young (18-30 years) and 112 middle-aged (40-65 years) adults completed the online survey. Results showed that earliest memories were rated either similar to or lower than later memories in their memory characteristics. More specifically. they received lower ratings than free-report memories in all memory characteristics whereas they did not significantly differ from recent memories only in importance and emotionality. In addition, free-report memories were highest in emotionality, importance and rehearsal frequency whereas recent memories were highest in vividness and confidence ratings. Compared to young adults, middle-aged adults provided higher ratings for all memory characteristics in general, and they further recalled earliest memories from an older age. Finally, the order of reporting the three types of memories (earliest memory first versus recent memory first) was examined with respect to its potential influence on memory characteristics and dating of the recalled memories. Results displayed no significant effect of the reporting order on memory characteristics. Dating of the earliest and free-report memories, however, was significantly affected by the reporting order. The mean age for earliest memories was higher when it was retrieved following the recent memory compared to the reporting order in which earliest memories are retrieved and reported first. Overall, results indicated that earliest memories arc not particularly special compared to later memories (e.g.. free-report memories) in terms of their memory characteristics, and they are vulnerable to experimental manipulation such as changing the reporting order just like other types of autobiographical memories.

Competitive Intelligence and Information Technology Adoption of Smes in Turkey: Diagnosing Current Performance and Identifying Barriers
(Halmstad University, 2013) Wright, Sheila; Bisson, Christophe; Duffy, Alistair P.
The need for SMEs to behave in a more concise and coherent competitive fashion is well recognised. This study reports on an empirical study of SMEs in Turkey. Their responses were applied to a behavioural and information technology adoption framework which enabled the identification of areas where changes would be required for these firms to begin operating at a higher level of competence. The findings revealed significant scope for improvements on all strands of the diagnostic framework: attitude gathering location technology support IT systems support and finally use of intelligence-based output by decision-makers. Through free form responses it was also possible to identify barrier to higher level adoption and performance inhibiters which were subsequently categorised and assessed for significance.

Conductivity Percolation of Carbon Nanotubes (cnt) in Polystyrene (ps) Latex Film
(Canadian Science Publishing Nrc Research Press, 2010) Uğur, Şaziye; Yargı, Önder; Pekcan, Önder
In this study the effect of multiwalled carbon nanotubes (MWNT) on film formation behaviour and electrical conductivity properties of polystrene (PS) latex film was investigated by using the photon transmission technique and electrical conductivity measurements. Films were prepared by mixing PS latex with different amounts of MWNTs varying in the range between 0 and 20 wt%. After drying MWNT content films were separately annealed above the glass transition temperature (T-g) of PS ranging from 100 to 270 degrees C for 10 min. To monitor film formation behavior of PS-MWNT composites transmitted light intensity I-tr was measured after each annealing step. The surface conductivity of annealed films at 170 degrees C was measured and found to increase dramatically above a certain fraction of MWNT (4 wt%) following the percolation theory. This fraction was defined as the percolation threshold of conductivity R-c. The conductivity scales with the mass fraction of MWNT as a power law with exponent 2.27 which is extremely close to the value of 2.0 predicted by percolation theory. In addition the increase in I-tr during annealing was explained by void closure and interdiffusion processes. Film formation stages were modeled and the corresponding activation energies were measured.
Converse Tournaments
(Ege Univ Fac Economics & Admin Sciences, 2019) Keskin, Kerim
This paper proposes two alternatives to Clark and Riis (1998b)'s sequential model of nested multiple-prize contests. First we consider winning prizes endogenously determined by exerted contest efforts. Second we extend the model to infinitehorizon. We characterize the unique subgame perfect Nash equilibrium in both models and compare the equilibrium strategies with those in the original model.

Corporate Governance and Tunneling: Empirical Evidence From Turkey
(Economics Bulletin, 2018) Akben Selçuk, Elif; Sener, Pınar
This study investigates whether internal governance mechanisms affect tunneling through intercorporate loans for a sample of Turkish listed non-financial firms over the period 2006 to 2014. While the findings reveal a significant and positive relationship between state ownership and tunneling and a significant and negative relationship between foreign ownership and tunneling the relationship between family ownership and tunneling is non-linear. In addition while board size is negatively associated with tunneling independent directors do not prevent the embezzlement of resources. Furthermore the results indicate that while older firms firms with family chairman and higher growth opportunities are more likely to engage in tunneling activities firm size high cash holding leverage and financial distress do not affect tunneling.

Corrected Panel-Reactive Antibody Positivity Rates for Hypersensitized Patients in Turkish Population With Calculated Panel-Reactive Antibody Software
(Elsevier Science Inc, 2017) Karadeniz, Sedat Tanju; Akgül, Sebahat Usta; Öğret, Yeliz; Çiftçi, Hayriye Şentürk; Bayraktar, Adem; Bakkaloğlu, Hüseyin; Çalışkan, Yaşar Kerem; Yelekçi, Kemal; Türkmen, Aydin; Aydın, Ali Emin; Oğuz, Fatma Savran; Çarin, Mahmut Nezih; Aydın, Filiz
however the rate was 86.2% using the cPRA. Discussion. cPRA shows the rate of the rejected donors according to all unacceptable antigens. The need for a list of unacceptable antigens in place of the PRA positivity rate is a real change in the sensitization-dependent calculation as cPRA positivity rate. Conclusion. In principal implementation of cPRA will encourage many centers and laboratories to adopt a standard measurement of sensitization in Turkey. It will increase the chances of better donor match particularly for hypersensitized patients by the creation of an unacceptable mismatch program using cPRA software.
