conclusions it seems that plantar changes have insignificant effect on static and dynamic indices evaluated by the biodex balance system. objectives the current study aimed to evaluate the relation between these structural characteristics and balance indices. patients and methods the study population was 100 male and female students from semnan university of medical sciences, semnan, iran. to e...

Abstract Data from the Large Hadron Collider on charge balance function in Pb+Pb collisions at center-of-mass energy 2.76 TeV per nucleon pair are analyzed and interpreted within framework of HYDJET++ model. This model allows us to qualitatively reproduce experimentally observed centrality dependence widths relatively low transverse momentum intervals due different creation mechanisms soft hard...

This paper presents transformerless multilevel converters as an application for high-power hybrid electric vehicle (HEV) motor drives. Multilevel converters: 1) can generate near-sinusoidal voltages with only fundamental frequency switching; 2) have almost no electromagnetic interference or common-mode voltage; and 3) make an HEV more accessible/safer and open wiring possible for most of an HEV...

Thermodynamic stability and refolding kinetics of firefly luciferase and three representative mutants with depletion of negative charge on a flexible loop via substitution of Glu by Arg (ER mutant) or Lys (EK mutant) as well as insertion of another Arg in ER mutants (ERR mutant) was investigated. According to thermodynamic studies, structural stability of ERR and ER mutants are enhanced compare...

Ultrafast optical pump-probe spectroscopy measurements on monolayer graphene reveal significant optical nonlinearities. We show that strongly photoexcited graphene monolayers with 35 fs pulses quasi-instantaneously build up a broadband, inverted Dirac-fermion population. Optical gain emerges and directly manifests itself via a negative conductivity at the near-infrared region for the first 200 ...
