Osteoporosis is a characterized by low bone mass and microarchitectural deterioration, with a consequent increase in bone fragility [1]. Bone strength impairment leads to an increased risk of fracture, as strenght reflects the integration of bone quantity (bone mineral density, BMD) and bone quality [2]. Common sites of osteoporotic fractures are spine, hip, distal forearm and proximal homerus....

A high-density array of plasmonic coaxial nanoantennas is used to enhance the two-photon absorption (TPA) process in a conventional silicon photodetector from a mode-locked 76 MHz Ti:sapphire laser over a spectral range from 1340 to 1550 nm. This enhanced TPA was used to generate an interferometric autocorrelation trace of a 150 fs laser pulse. Unlike second-harmonic generation, this technique ...

Testing and improvements of gamma-ray strength functions for nuclear model calculations of nuclear data Kiev SUMMARY A closed-form thermodynamic pole approach, TPA, is developed for average description of the E1 radiative strength functions using the microcanonical ensemble for initial states. The method can be applied to calculate the dipole strengths in heated and cold nuclei for processes of...

background: as bremsstrahlung photon beam fluence is important parameter to be known in a photonuclear reaction experiment as the number of produced particle is strongly depends on photon fluence. materials and methods: photon production yield from different thickness of aluminum target has been estimated using artificial neural network (ann) model. target thickness and incoming electron energy...

BACKGROUND AND PURPOSE Tissue-type plasminogen activator (tPA) is the only acute treatment for ischemic stroke. Unfortunately, the benefit of tPA-driven thrombolysis is not systematic, and understanding the reasons for this is mandatory. The balance between beneficial and detrimental effects of tPA might explain the limited overall efficiency of thrombolysis. Here, we investigated whether this ...
