Wavelets in Field Theory

We advocate the use of Daubechies wavelets as a basis for treating a variety of problems in quantum field theory. This basis has both natural large volume and short distance cutoffs, has natural partitions of unity, and the basis functions are all related to the fixed point of a linear renormalization group equation.Comment: 42 pages, 2 figures, corrected typo

Predicting the Impact of Batch Refactoring Code Smells on Application Resource Consumption

Automated batch refactoring has become a de-facto mechanism to restructure software that may have significant design flaws negatively impacting the code quality and maintainability. Although automated batch refactoring techniques are known to significantly improve overall software quality and maintainability, their impact on resource utilization is not well studied. This paper aims to bridge the gap between batch refactoring code smells and consumption of resources. It determines the relationship between software code smell batch refactoring, and resource consumption. Next, it aims to design algorithms to predict the impact of code smell refactoring on resource consumption. This paper investigates 16 code smell types and their joint effect on resource utilization for 31 open source applications. It provides a detailed empirical analysis of the change in application CPU and memory utilization after refactoring specific code smells in isolation and in batches. This analysis is then used to train regression algorithms to predict the impact of batch refactoring on CPU and memory utilization before making any refactoring decisions. Experimental results also show that our ANN-based regression model provides highly accurate predictions for the impact of batch refactoring on resource consumption. It allows the software developers to intelligently decide which code smells they should refactor jointly to achieve high code quality and maintainability without increasing the application resource utilization. This paper responds to the important and urgent need of software engineers across a broad range of software applications, who are looking to refactor code smells and at the same time improve resource consumption. Finally, it brings forward the concept of resource aware code smell refactoring to the most crucial software applications

Erkek üretrası içinde kulak temizleme çubuğu : alışılmadık üretral yabancı cisme ait vaka raporu

Urethral foreign bodies are rare urological emergencies and early management is vital. Mostly, the patient with a psychiatric disorder inserts the foreign body himself for erotic satisfaction. In this paper, we reported a case of a 22-year-old male patient who inserted a cotton swab into his urethra.Üretral yabancı cisimler, az rastlanan fakat erken müdahalenin hayati olduğu ürolojik acillerdendir. Çoğunlukla, psikiyatrik bir sorunu olan hasta erotik tatmin amacıyla yabancı cismi kendi yerleştirmektedir. Biz bu yazıda , kendi üretrasına kulak temizleme çubuğu yerleştiren 22 yaşındaki erkek hastaya ait bir vakayı raporladık

THE EFFECT OF BLOOD CONTAMINATION ON SHEAR BOND STRENGTH OF CALCIUM SILICATE-BASED PULP CAPPING MATERIALS

Objectives: The aim of this study was to examine the effect of different hardening times and blood contamination of MTA and Biodentine, which are widely used for pulp capping treatments in the market, on shear bond strength (SBS) with a self-etch adhesive resin, after different hardening times (24, 48, 72 and 96 hours). Materials and Methods: Slots with a diameter of 5 mm and a height of 2 mm were prepared in 192 acrylic blocks for this study. Both ProRoot MTA and Biodentine were prepared according to the manufacturer’s instructions, and half of the slots were filled with ProRoot MTA and the other half were filled with Biodentine. All the samples were divided into groups depending on four different hardening times and hardened. After hardening process completed, the group of each hardening time was divided into 2 subgroups (n:12) with and without contamination. In the uncontaminated groups, a self-etch adhesive resin (Clearfil Liner Bond) and a resin-based composite (Filtek P60) were applied on the samples and polymerized. In the contaminated groups, the sample surfaces were contaminated with blood for 20 seconds. After washing and drying the samples, adhesive resin and composite were applied on them. After that SBS tests were performed and the data were subjected to a 2-way ANOVA test analysis. Results: In the uncontaminated groups, there was no significant difference in the SBS of each pulp capping material depending on different hardening times (p>0.05). ProRoot MTA showed statistically higher SBS than Biodentine in the 72 and 96 hour uncontaminated groups (p<0.05). Blood contamination caused a significant decrease in the SBS of ProRoot MTA and Biodentine (p<0.05). Conclusions: In this study, it was determined that blood contamination reduces the SBS of pulp capping materials. Therefore, it is recommended to prolong the hardening times of the capping materials and to take clinical measures to prevent blood contamination as much as possible before restorative treatments are performed
