Radiative corrections to the Zemach contribution of the hydrogen hyperfine splitting are calculated. Their contributions amount to −0.63(3) ppm to the HFS. The radiative recoil corrections are estimated to be 0.09(3) ppm and heavy particle vacuum polarization shifts the HFS by 0.10(2) ppm. The status of the nuclear-dependent contributions are considered. From the comparison of theory and experi...

Recently, a novel hesitant fuzzy set (HFS) ranking technique based on the idea of lexicographical ordering is proposed and an example is presented to demonstrate that the proposed ranking method is invariant with multiple occurrences of any element of a hesitant fuzzy element (HFE). In this paper, we show by examples that the HFS lexicographical ordering method is sometimes invalid, and a modif...

Background & Aim: To assess functionality status and surgical outcome of fenestration versus laminotomy technique based on Core Outcome Measures Index (COMI) in patients with lumbar disc hernia (LDH). Methods & Materials/Patients: A cross-sectional study was performed between January 2007 and April 2012. A total of 108 patients with a single-level disc herniation were asked to respond to the...

Using advanced Laser spectroscopy methods, nuclear ground state spins, moments, charge radii, of radioactive nuclei can be determined. The optical techniques, based on hyperfine structure splitting (HFS) or isotope shift measurements, yield model-independent information about the nucleus. Various experimental methods and concepts are proposed to take advantage of the exotic nuclei provided at l...

Recent progress in the spectroscopy of antiprotonic helium has allowed for measuring the separation between components of the hyperfine structure (HFS) of the (37, 35) metastable states with an accuracy of 300 MHz, equivalent to a relative accuracy of 3.10. The analysis of the uncertainties of the available theoretical results on the antiprotonic helium HFS shows that the accuracy of the value ...

The concept of functionality oriented programming is proposed, and some of its aspects are discussed, such as: (1) implementation independent basic types and generic collection types; (2) syntax requirements and recommendations for implementation independence; (3) unified documentation and code; (4) cross-module interface; and (5) cross-language program making scheme. A prototype example is giv...

Background and Aims: This research is carried out with the aim of comparing anxiety, depression and global assessment of functioning between two groups of bipolar patients at mixed and manic episodes. Methods: Using an analytical cross-sectional approach, a sample of 94 patients with mean age of 32 years old (Standard Deviation: 11.3), who had been categorically diagnosed with bipolar disorder ...
