Dasatinib and quercetin prevent alveolar bone loss in aged mice
Journal of Periodontology, EarlyView.Abstract Background Recent findings have associated alveolar bone loss (ABL) with the presence of senescent cells. Aging and the accumulation of senescent cells are associated with a pro‐inflammatory environment which may exacerbate tissue damage.

Genetic-Algorithm-Assisted Multiuser Detection in Asynchronous CDMA Communications
, 2004 —In an asynchronous direct-sequence code-division multiple-access, a specific bit of the reference user is interfered by two asynchronously arriving surrounding bits of all the other users supported by the system.

Journal of Surfactants and Detergents, EarlyView.ABSTRACT Striae distensae are common dermal lesions that negatively affect skin appearance, and topical management remains limited by challenges related to skin deposition and residence time. Here, we developed transparent surfactant‐based isotropic systems for the topical co‐delivery of ascorbic acid (AA), retinoic acid (RA), and lavender essential ...

Minimum bit error rate multiuser transmission designs using particle swarm optimisation
, 2009 We consider the downlink of a multiuser system equipped with multiple antennas transmitting to multiple single-antenna mobile receivers. Particle swarm optimisation (PSO) is invoked to solve the constrained nonlinear optimisation problem for the minimum ...

Low complexity uplink multiuser MIMO detecting algorithm
Tongxin xuebao, 2010 Aiming at the uplink multiuser MIMO system,a new space-time detecting algorithm was proposed,in which a linear recombination strategy was imposed on the received signal first,and then the matched filter vectors orthogonal to each users’ interference sets
