SOME CONDITIONS ON STARLIKE AND CLOSE TO CONVEX FUNCTIONS

Many mathematical concepts are explained when viewed through complex function theory. We are here basically concerned with the form f(z) = a(0) + a(1)z + a(2)z(2) +.... f(z) is an element of A, f(z) = z + Sigma(infinity)(n=2)a(n)z(n) will be an analytic function in the open unit disc U = {z : |z| < 1,z is an element of C} normalized by f(0) = 0, f '(0) = 1. In this work, starlike functions and close-to-convex functions with order 1/4 have been studied according to the exact analytic requirements

The intend of this paper is to study on different production routes of medical 66,67Ga and 75Se radionuclides used in cancer diagnostic. Both 66,67Ga and 75Se are the most well-known radionuclides used in diagnostics of malignant and benign tumors also brain studies and scintigraphy scanning. For this purpose, production cross–section calculations of medical 66,67Ga and 75Se radionuclides have been calculated for 64Zn(3He,p)66Ga, 65Cu(3He,2n)66Ga, 65Cu(3He,n)67Ga, 66Zn(3He,n+p)67Ga, 69Ga(3He,n+α)67Ga, 76Se(3He,α)75Se, 77Se(3He,n+α)75Se reactions.

The models which have been employed within the calculations are Two Component Exciton and Equilibrium of TALYS 1.8 and Hybrid and Geometry Dependent Hybrid of ALICE/ASH. The results obtained from the calculations for each reaction have been compared with other calculation results and previously recorded experimental values collected from the Experimental Nuclear Reaction Data (EXFOR) library.No sponso

Novel approximate absolute difference hardware

Approximate hardware designs have higher performance, smaller area or lower power consumption than exact hardware designs at the expense of lower accuracy. Absolute difference (AD) operation is heavily used in many applications such as motion estimation (ME) for video compression, ME for frame rate conversion, stereo matching for depth estimation. Since most of the applications using AD operation are error tolerant by their nature, approximate hardware designs can be used in these applications. In this paper, novel approximate AD hardware designs are proposed. The proposed approximate AD hardware implementations have higher performance, smaller area and lower power consumption than exact AD hardware implementations at the expense of lower accuracy. They also have less error, smaller area and lower power consumption than the approximate AD hardware implementations which use approximate adders proposed in the literature

Evaluation of personality features and mental state of keratoconus patients

Objectives: Keratoconus (KCN) is a disorder that usually appears during adolescence and progressively reduces visual acuity. KCN may lead to differences in personality features as a result of vision loss and the numerous clinical examinations and treatment methods used from a young age. The aim of this study was to better understand the psychological characteristics of KCN patients and to define possible correlations between corneal topographic parameters and psychological state. Methods: A total of 59 KCN cases were included in the study group and were compared with 65 age- and sex-matched healthy individuals. All of the participants underwent a routine ophthalmic examination that included corrected distance visual acuity (CDVA), biomicroscopy, and fundoscopy. The KCN patients were evaluated busing Scheimpflug corneal topography. Psychiatric evaluations were performed using the Eysenck Personality Questionnaire Revised-Short Form (EPQ), the Self-Confidence Scale, the Maudsley Obsessive-Compulsive Inventory (MOCI), and the Beck Depression Inventory (BDI). Results: The mean age of the case and control groups was 23.98±5.7 years and 25.82±5.4 years, respectively. The KCN cases had significantly higher EPQ neuroticism subscale scores; higher MOCI subscale scores, with the exception of the doubting subscale; and higher BDI scores. Analysis of the KCN duration revealed a positive correlation with the checking and slowness subscales of the MOCI, however, there was no significant correlation between the psychometric scale scores, corneal topographic parameters, and CDVA. Conclusion: A substantially asymmetrical course and a relatively long period for KCN to result in severe vision loss might explain the lack of correlations between psychological parameters and visual acuity. Nonetheless, the apparent effect of vision loss on emotional distress cannot be disregarded; the day-to-day progressive loss of visual acuity and multiple, costly interventions may initiate or contribute to a depressive mood in KCN patients. A vicious depressive cycle and the exhaustion of long-term coping mechanisms might be underlying factors for the higher neuroticism scores seen among KCN patients. Both the personality traits and mental state of KCN patients demonstrate distinguishing properties; clinicians working with these patients should consider their mental state in addition to other factors in order to achieve better treatment outcome

Investigation of the effects of some level density models in the production cross- section calculations of 75-77Br radioisotopes

Radyoizotopların kullanım alanları, gelişen teknoloji ve bilimsel ilerlemeler sayesinde giderek yaygınlaşmış ve çeşitlenmiştir. Radyoizotopların en yaygın kullanıldığı alan ise medikal teşhis ve tedavi uygulamalarıdır. Bu amaçlarla kullanılan pek çok radyoizotop arasında karakteristik özellikleri ve uygulamalardaki faydaları nedeniyle 75-77Br radyoizotopları da bulunmaktadır. Medikal uygulamalarda radyoizotopların sahip oldukları etki ve değer neticesinde bu izotopların üretim rotaları ile ilgili çalışmalar da literatüre katkı sağlayan çalışmalar olmuştur. Bu kapsamda, deneysel çalışmaların gerçekleştirilemediği durumlarda araştırmacılara bilgi verebilecek çeşitli parametrelerin elde edilmesinde farklı teorik modellerin kullanımı oldukça yaygındır. Kısaca bir reaksiyonun gerçekleşme ihtimali olarak açıklanabilecek tesir kesiti değeri de araştırmacılar için önemli bir parametredir ve bu değerin hesaplanmasında etkili faktörlerden biri de seviye yoğunluğu modelleridir. Tüm bunlar göz önüne alınarak bu çalışmada, 75-77Br radyoizotoplarının bazı (p,xn) reaksiyonları ile üretim tesir kesiti hesaplamalarında bazı seviye yoğunluğu modellerinin etkilerinin araştırılması amaçlanmıştır. Hesaplamalarda TALYS kodunun 1.9 sürümü kullanılmış ve elde edilen hesaplama sonuçları literatürde mevcut olan deneysel veriler ile karşılaştırılmıştır.The use of radioisotopes has become increasingly widespread and diversified thanks to advancing technology and scientific advances. The most widely used field of radioisotopes are medical diagnosis and treatment applications. Among the many radioisotopes used for these purposes, there are also 75-77Br radioisotopes due to their characteristics and benefits in applications. As a result of the impact and value of radioisotopes in medical applications, studies on the production routes of these isotopes have also contributed to the literature. In this context, the use of different theoretical models is quite common in obtaining various parameters that can inform researchers in cases where experimental studies cannot be carried out. The cross±section value, which can be explained briefly as the probability of a reaction, is an important parameter for the researchers and one of the effective factors in the calculation of this value is the level density models. Considering all these, in this study, it is aimed to investigate the effects of some level density models in the production cross±section calculations with some (p,xn) reactions of 75-77Br radioisotopes. In calculations, 1.9 version of TALYS code was used and the results obtained were compared with the experimental data available in the literature.No sponso
