Spin degrees of freedom and flattening of the spectra of single-particle excitations in strongly correlated Fermi systems

open access: yes, 2003
The impact of long-range spin-spin correlations on the structure of a flat portion in single-particle spectra $\xi(p)$, which emerges beyond the point, where the Landau state loses its stability, is studied. We supplement the well-known Nozieres model of

Nucleon-antinucleon Interaction from the Modified Skyrme Model [PDF]

open access: yes, 2007
We calculate the static nucleon-antinucleon interaction potential from the modified Skyrme model with additional $B^{\mu}B_{\mu}$ term using the product ansatz. The static properties of single baryon are improved in the modified Skyrme model.

Experimental Researches on Long-Term Strength of Granite Gneiss

open access: yesAdvances in Materials Science and Engineering, 2015
It is important to confirm the long-term strength of rock materials for the purpose of evaluating the long-term stability of rock engineering. In this study, a series of triaxial creep tests were conducted on granite gneiss under different pore pressures.

Prediction of concrete compressive strength due to long term sulfate attack using neural network

open access: yesAlexandria Engineering Journal, 2014
This work was divided into two phases. Phase one included the validation of neural network to predict mortar and concrete properties due to sulfate attack. These properties were expansion, weight loss, and compressive strength loss.

Long-term variation in the Sun's activity caused by magnetic Rossby waves in the tachocline [PDF]

open access: yes, 2015
Long-term records of sunspot number and concentrations of cosmogenic radionuclides (10Be and 14C) on the Earth reveal the variation of the Sun's magnetic activity over hundreds and thousands of years.

Long-term strength properties of HVFA concretes [PDF]

open access: yesIOP Conference Series: Materials Science and Engineering, 2015
Fly ash from coal burning is used as active addition for concrete in Middle-Europe region for several decades. The intensity of its utilization increases still. In the role of supplementary cement addition it serves as binder, whereby it helps to reduce final price of concrete as well as improves both the rheological properties of fresh concrete and ...

Why and When Are Evidence‐Based Interventions Adopted in Paediatric Supportive Care? A Qualitative Exploration of the Determinants of Photobiomodulation Implementation

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Oral mucositis is a common and debilitating side effect of childhood cancer and stem cell transplant treatments. It affects the quality of life of children and young people (CYP) and places a strain on services. Photobiomodulation is recommended for oral mucositis prevention in international guidance but is poorly implemented in UK ...
