Polyvinyl alcohol (PVA)-stabilized graphene nanosheets (GNS) of lateral dimension (L) ~1 μm are obtained via liquid phase exfoliation technique to prepare its composites in the PVA matrix. These composites show low levels of reinforcements due to poor alignment of GNS within the matrix as predicted by the modified Halpin-Tsai model. Drawing these composites up to 200 % strain, a significant imp...

Recently, Tsai proposed an efficient nonce-based authentication scheme for session initiation protocol (T-SIP for short). However, the author shall show that T-SIP is vulnerable to perfect forward secrecy, password guessing attacks, and insider attacks.

Alexander Tsai and colleagues highlight the complex relationship between poverty and HIV stigma in sub-Saharan Africa, and discuss possible ways to break the cycle. Please see later in the article for the Editors' Summary.

Following in the recent work of Hurvich and Tsai (1989, 1991, 1993) and Hurvich, Shumway, and Tsai (1990), we propose a corrected variant of AIC developed for the purpose of small-sample state-space model selection. Our variant of AIC utilizes bootstrapping in the state-space framework (Stoffer and Wall (1991)) to provide an estimate of the expected Kullback-Leibler discrepancy between the mode...
