Almost K\"ahler structures on four dimensional unimodular Lie algebras
, 2012 Let $J$ be an almost complex structure on a 4-dimensional and unimodular Lie algebra $\mathfrak{g}$. We show that there exists a symplectic form taming $J$ if and only if there is a symplectic form compatible with $J$.

Energy Science &Engineering, EarlyView.Mine‐water immersion tests reveal pronounced coal weakening (vs. minor concrete degradation), identifying coal pillars as the stability‐limiting component in composite dams. A coupled FEINN framework quantifies extreme‐pressure stability and ranks multi‐parameter designs via a normalized multi‐indicator scheme, enabling optimized dam configuration for ...

Threshold Password-Based Authentication Using Bilinear Pairings [PDF]
, 2004 We present a new threshold password-based authentication protocol that allows a roaming user(a user who accesses a network from different client terminals) to download a private key from remote servers with knowledge of only his identity and password. He does not need to carry the smart card storing his private information.

Solar Geoengineering Effects on Malaria Transmission Risk in South Asia Under G6sulfur Scenario
International Journal of Climatology, EarlyView.Comparison of EIR (unit: No of infected bites per person per day) for each considered country in South Asia, under the considered scenarios, averaged over the period 2020–2090. A regression equation is shown for each country (for Bhutan EIRG = 0.1690 × 10−10 EIRS + 0.5968 × 10−12) to illustrate the projected trend.

Laser &Photonics Reviews, EarlyView.A Cr3+/La3+ codoped Sr3Zr2O7 NIR phosphor showing luminescence at ∼960 nm with high IQE/EQE (92.4%/57.5%) and good thermal stability was developed. La3+ stabilizes Cr3+ and induces Cr3+ pairs, enabling efficient blue‐to‐NIR conversion for underwater wireless optical communication.

Policy-based encryption schemes from bilinear pairings
Proceedings of the 2006 ACM Symposium on Information, computer and communications security, 2006 The concept of policy-based cryptography is a promising paradigm for trust establishment and authorization in largescale open environments like the Internet and Mobile Networks. It aims at providing a framework for performing cryptographic operations with respect to policies formalized as monotone Boolean expressions written in standard normal forms. A

Asymptotics for the Spectrum of the Laplacian in Thin Bars with Varying Cross Sections
Mathematical Methods in the Applied Sciences, EarlyView.ABSTRACT We consider spectral problems for the Laplace operator in 3D rod structures with a small cross section of diameter O(ε)$$ O\left(\varepsilon \right) $$, ε$$ \varepsilon $$ being a positive parameter. The boundary conditions are Dirichlet (Neumann, respectively) on the bases of this structure, and Neumann on the lateral boundary.

Optimistic Mix-net protocol based on bilinear pairings
Tongxin xuebao, 2013 A novel pairing-based optimistic Mix-net scheme was proposed. The key management is made easier by em-ploying bilinear paring primitives and there is no need for the participating mix servers to re-generate keys jointly be-tween mix-sessions to avoid ...

Journal of King Saud University: Computer and Information Sciences, 2014 Several certificateless short signature and multisignature schemes based on traditional public key infrastructure (PKI) or identity-based cryptosystem (IBC) have been proposed in the literature; however, no certificateless short sequential (or serial ...

Efficient Certificateless Signcryption from Bilinear Pairings
International Journal of Security and Its Applications, 2016 Certificateless public key cryptography is an attractive paradigm which combines advantages of both traditional certificate-based and ID-based public key cryptosystems. In this paper, the author formalizes the definition and the security model for certificateless signcryption (CLSC), and proposes a CLSC scheme that is proved to be secure in the random ...
