Neuromorphic computing architectures demand development of analog, non-volatile memory components operating at femto-Joule/bit operation energy. Electronic working this energy range require devices ultrafast timescales. Among different...

We investigated the production of neutralino pairs via photon-photon collisions in the minimal supersymmetric model(MSSM) at future linear colliders. The numerical analysis of their production rates is carried out in the mSUGRA scenario. The results show that this cross section can reach about 18 femto barn for χ̃1χ̃ 0 2 pair production and 9 femto barn for χ̃2χ̃ 0 2 pair production with our chosen...

Objective: To compare the ocular surface changes following Femtosecond laser in situ keratomileusis (Femto-LASIK) and photorefractive keratectomy (PRK). Material Methods: TThis prospective study included 74 eyes of 37 patients: 34 were Femto-LASIK group, 40 PRK group. Schirmer test, tear break-up time, conjunctival impression cytology (CIC) used to determine before 1 month, 3 months after or Fe...

We report a new design of single-shot cross-correlation frequency-resolved optical gating (XFROG) with sub femto-joule sensitivity for complete field characterization of ultrashort optical pulse using a 400- nm-pumped type-I noncollinear optical parametric amplifier. Optical parametric gain as high as 10(8) with 0.8-0.9 femto-joules sensitivity had been demonstrated with an un-cooled CCD in thi...

PURPOSE To compare toric implantable collamer lens (T-ICL), femto-LASIK, and ReLEx SMILE for the treatment of low to moderate myopic astigmatism in terms of long-term visual and refractive outcomes and predictability of astigmatic correction. MATERIALS AND METHODS The study included 30 eyes from 30 patients between the age groups of 21 and 40 years, undergoing bilateral surgery with any of th...
