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.

Iterative Spectrum Shaping with Opportunistic Multiuser Detection

, 2009
This paper studies a new decentralized resource allocation strategy, named iterative spectrum shaping (ISS), for the multi-carrier-based multiuser communication system, where two coexisting users independently and sequentially update transmit power ...

Rational acquisition of laboratory equipment: an accurate mathematical model to estimate the trade‐offs in shared and nonshared equipment

Acta Crystallographica Section D, EarlyView.
We present a quantitative framework combining cost modelling and queueing theory to estimate hourly access costs, waiting times and congestion levels for shared high‐end scientific equipment. The approach is general, illustrated with cryo‐electron microscopy examples, and implemented in an open‐access online calculator to support evidence‐based ...

SVD-Aided Beamforming and Power Allocation Algorithm for Multiuser Turbo-BLAST System Uplink with Imperfect CSI

International Journal of Antennas and Propagation, 2012
The SVD-aided joint transmitter and receiver design for the uplink of CDMA-based synchronous multiuser Turbo-BLAST systems is proposed in the presence of channel state information (CSI) imperfection.

Dynamical replica theoretic analysis of CDMA detection dynamics

, 2005
We investigate the detection dynamics of the Gibbs sampler for code-division multiple access (CDMA) multiuser detection. Our approach is based upon dynamical replica theory which allows an analytic approximation to the dynamics.

Assessing Clinical Competence of Postgraduate Dental Specialty Trainees: A Scoping Review

European Journal of Dental Education, EarlyView.
ABSTRACT Background Assessment is essential to ensure that trainees meet competency standards in delivering patient care. However, a comprehensive summary of the literature on clinical assessment in postgraduate dental education is largely absent. Filling this gap is essential for developing effective assessment processes to help support competency ...

Flavobacterium oreochromis From Farmed Tambaqui (Colossoma macropomum): Insights Into Genetic, Phenotypic and Pathogenic Diversity

Journal of Fish Diseases, EarlyView.
ABSTRACT Flavobacterium spp. are the etiological agents of columnaris disease. Although there is evidence that columnaris poses a significant threat to the farming of tambaqui (Colossoma macropomum), there remains a large gap in understanding the genetic and phenotypic diversities of columnaris‐causing bacteria (CCB).
