Strategies for the evolution of sex
(American Physical Soc, One Physics Ellipse, 2001-12)We find that the hypothesis made by Jan, Stauffer, and Moseley [Theory Biosci. 119, 166 (2000)] for the evolution of sex, namely, a strategy devised to escape extinction due to too many deleterious mutations, is sufficient ... -
Coherent array imaging using phased subarrays. Part II: Simulations and experimental results
(IEEE-INST Electrical Electronics Engineers Inc, 2005-01)The basic principles and theory of phased subarray (PSA) imaging imaging provides the flexibility of reducing I he number of front-end hardware channels between that of classical synthetic aperture (CSA) imaging-which uses ... -
Coherent-array imaging using phased subarrays. Part I: Basic principles
(IEEE-INST Electrical Electronics Engineers Inc, 2005-01)The front-end hardware complexity of a coherent array imaging system scales with the number of active array elements that are simultaneously used for transmission or reception of signals. Different imaging methods use ... -
Comment on "Encryption and decryption of images with chaotic map lattices" [Chaos 16, 033118 (2006)]
(American Institute of Physics Inc., 2008-09)In this paper, we comment on the chaotic encryption algorithm proposed by A. N. Pisarchik et al. [Chaos 16, 033118 (2006)]. We demonstrate that the algorithm is not invertible. We suggest simple modifications that can ... -
Spherical coding algorithm for wavelet image compression
(IEEE-Inst Electrical Electronics Engineers Inc, 2009-05)In recent literature, there exist many high-performance wavelet coders that use different spatially adaptive coding techniques in order to exploit the spatial energy compaction property of the wavelet transform. Two crucial ... -
Minimally redundant 2-D array designs for 3-D medical ultrasound imaging
(IEEE-Inst Electrical Electronics Engineers Inc, 2009-07)In real-time ultrasonic 3-D imaging, in addition to difficulties in fabricating and interconnecting 2-D transducer arrays with hundreds of elements, there are also challenges in acquiring and processing data from a large ... -
Nonreciprocal switching of VO2 thin films on microstructured surfaces
(Optical Soc Amer, 2010-05-15)We demonstrate that the combination of near-field focusing and a switchable oxide layer permits construction of a modulator with different optical switching thresholds in two opposing directions. For that purpose VO2 layers ... -
Moral reasoning and moral orientation of U.S. and Turkish university students
(Ammons Scientific, 2010-10)Participants from an individualistic society (USA) were compared with participants from a collectivistic society (Turkey) in terms of moral reasoning and orientation (justice and care). A total of 396 undergraduates (203 ... -
Dissolution and subsequent re-crystallization as zeroing mechanism, thermal properties and component resolved dose response of salt (NaCl) for retrospective dosimetry
(Pergamon-Elsevier Science Ltd, 2011-09)In the present study we report dosimetric properties of iodized salt aiming at using it as an accidental luminescent dosimeter. It was found that the very good sensitivity of its main dosimetric peak is strongly affected ... -
Optimizing circular ring arrays for forward-looking IVUS imaging
(IEEE-Inst Electrical Electronics Engineers Inc, 2011-12)Forward-looking (FL) catheter-based imaging systems are highly desirable for guiding interventions in intravascular ultrasound (IVUS) applications. One of the main challenges of array-based FL-IVUS systems is the large ... -
Effects of olive oil mill waste water (omww) on the frog larvae
(Springer, 2012-08)In this research, acute effect of the olive oil mill wastewater (OMWW) on the frog larvae has been studied. Larvae showed hyperactivity symptoms first and loss of balance and remained motionless due to toxicity of wastewater. ... -
Efficient privacy-aware record integration
(2013)The integration of information dispersed among multiple repositories is a crucial step for accurate data analysis in various domains. In support of this goal, it is critical to devise procedures for identifying similar ... -
The function of regressions in reading: Backward eye movements allow rereading
(Springer, 2013-01)Standard text reading involves frequent eye movements that go against normal reading order. The function of these "regressions" is still largely unknown. The most obvious explanation is that regressions allow for the ... -
Uncontrolled avoidance of threat: Vigilance-avoidance, executive control, inhibition and shifting
(Routledge Journals, 2014)It has been argued that anxious individuals orient their attention initially towards and then away from threat; this pattern is known as vigilance-avoidance. While the mechanisms underlying the initial vigilance have been ... -
An improved robust stability result for uncertain neural networks with multiple time delays
(Pergamon-Elsevier Science Ltd, 2014-06)This paper proposes a new alternative sufficient condition for the existence, uniqueness and global asymptotic stability of the equilibrium point for the class of delayed neural networks under the parameter uncertainties ... -
Effects of childhood trauma and clinical features on determining quality of life in patients with bipolar I disorder
(Elsevier Science BV, 2014-06-20)Background: We explored how childhood trauma (CHT) affects the clinical expression of disorder and quality of life in patients with bipolar I (BP I) disorder.Methods: Euthymic patients (n=116) who subsequently received a ... -
Analysis of entanglement measures and LOCC maximized quantum fisher information of general two qubit systems
(Nature Publishing Group, 2014-06-24)Entanglement has been studied extensively for unveiling the mysteries of non-classical correlations between quantum systems. In the bipartite case, there are well known measures for quantifying entanglement such as ... -
The relationship between a mother's attitude toward domestic violence and children's schooling outcomes in Turkey
(Sage Publications Inc, 2014-09)This study explores the relationship between a mother's attitude toward domestic violence and her children's schooling outcomes in Turkey. The sample is drawn from the 2003 Turkish Demographic and Health Survey and consists ... -
Assessment of algorithms for mitosis detection in breast cancer histopathology images
(Elsevier Science BV, 2015-02)The proliferative activity of breast tumors, which is routinely estimated by counting of mitotic figures in hematoxylin and eosin stained histology sections, is considered to be one of the most important prognostic markers. ... -
Attentional bias and training in social anxiety disorder
(Turkish Neuropsychiatric Society, 2015-03)Cognitive behavioral therapy (CBT) is one of the most effective treatment modalities for social anxiety disorder (SAD), showing a high level of clinical evidence supporting its effectiveness. On the other hand, lack of the ...
