The long time follow-up of craniovertebral junction fixation in patients with rheumatoid arthritis
(Elsevier, 2013)
Background: Rheumatoid arthritis (RA) can have very destructive effects, especially in the cervical spine. Bone quality is poor in these patients. The purpose of this study is to evaluate the feasibility of fusion and ...
Intelligent Association Rules for Innovative SME Collaboration
(Springer New York LLC, 2015)
SMEs are encouraged to collaborate for research and innovation in order to survive in tough global competition. Even the technology SMEs with high knowledge capital have the fear to collaborate with other SMEs or bigger ...
C1-2 posterior arthrodesis technique with a left segmental and right transarticular fixation. A hybrid novel (Kotil) technique
(Medknow Publications, 2014)
Introduction: The most commonly used techniques for C1-C2 posterior arthrodesis are Goel and Magerl fixation techniques. Due to the anatomical variations of the region, the prior determination of the surgical technique ...
Raman frequencies calculated at various pressures in phase I of benzene
(KCS Publications, 2013)
We calculate in this study the pressure dependence of the frequencies for the Raman modes of A (Ag), B (Ag, B2g) and C (B1g, B3g) at constant temperatures of 274 and 294K (room temperature) for the solid phase I of benzene. ...
An extremely giant lumbar schwannoma: New classification (Kotil) and mini-open microsurgical resection
(Korean Society of Spine Surgery 1, 2014)
Purely extradural giant lumbar schwannomas are rare lesions. Classification of these tumors is performed according to the sizes and spills and is named the modified Sridhar's classification. The management of these tumors ...
Study of e+e- →π+π-π0ηc and evidence for Zc (3900)± decaying into ρ±ηc STUDY of e+e- →π+π-π0ηc ... M. ABLIKIM et al.
(American Physical Society, 2019)
We study the reaction e+e-→π+π-π0ηc for the first time using data samples collected with the BESIII detector at center-of-mass energies s=4.226, 4.258, 4.358, 4.416, and 4.600 GeV. Evidence of this process is found and the ...
Search for the decay D-s(+) -> p(p)over-bare(+) nu(e)
(American Physical Society, 2019)
Using a 3.19 fb-1 data sample collected at the s=4.178 GeV with the BESIII detector, we search for the rare decay Ds+→ppe+νe. No significant signal is observed, and an upper limit of B(Ds+→ppe+νe)<2.0×10-4 is set at the ...
Observation of the Semileptonic D+ Decay into the K 1 (1270)0 Axial-Vector Meson
(American Physical Society, 2019)
By analyzing a 2.93 fb-1 data sample of e+e- collisions, recorded at a center-of-mass energy of 3.773 GeV with the BESIII detector operated at the BEPCII collider, we report the first observation of the semileptonic D+ ...
Application of artificial intelligence algorithms on modeling of reflection phase characteristics of a nonuniform reflectarray element
(John Wiley and Sons Ltd, 2020)
Reflectarray antennas (RAs) have the ability to combine the advantages of both traditional parabolic reflector and phased array antennas without the need for feed network designs. Microstrip reflectarrays (MRAs) have the ...
Observation of the Leptonic Decay D+ →τ+ντ
(American Physical Society, 2019)
We report the first observation of D+→τ+ντ with a significance of 5.1σ. We measure B(D+→τ+ντ)=(1.20±0.24stat±0.12syst)×10-3. Taking the world average B(D+→μ+νμ)=(3.74±0.17)×10-4, we obtain Rτ/μ=Γ(D+→τ+ντ)/Γ(D+→μ+νμ)=3.21 ...
