Hydrogen-Bond-Dynamics-Based Switching of Conductivity and Magnetism: A Phase Transition Caused by Deuterium and Electron Transfer in a Hydrogen-Bonded Purely Organic Conductor Crystal
Akira Ueda,Shota Yamada,Shota Yamada,Takayuki Isono,Hiromichi Kamo,Akiko Nakao,Reiji Kumai,Hironori Nakao,Youichi Murakami,Kaoru Yamamoto,Yutaka Nishio,Hatsumi Mori +11 more
TL;DR: An unprecedented H-bond-dynamics-based switching of electrical conductivity and magnetism in a H- bonded purely organic conductor crystal, κ-D3(Cat-EDT-TTF)2 (abbreviated as δ-D), is reported, proving that the H-Bonded deuterium dynamics and the conducting TTF π-electron are cooperatively coupled.

Generic constructions for chosen-ciphertext secure attribute based encryption
TL;DR: This paper exhaustively checks the verifiability of existing ABE schemes and found that most of them satisfy such a property, hence CCA-secure versions of these schemes can be obtained automatically.

Partitioning via Non-linear Polynomial Functions: More Compact IBEs from Ideal Lattices and Bilinear Maps
Shuichi Katsumata,Shota Yamada +1 more
TL;DR: In this paper, Chen et al. proposed a secure IBE scheme based on the hardness of a computational/search problem, rather than a decisional problem such as DDH and DLIN on bilinear maps with sublinear public parameter size.

A Framework and Compact Constructions for Non-monotonic Attribute-Based Encryption
TL;DR: This paper proposes new non-monotonic attribute-based encryption schemes with compact parameters, and introduces special type of predicate encryption that is two-mode identity based broadcast encryption TIBBE, and shows that any T IBBE scheme that satisfies certain condition can be generically converted into non-Monotonic KP-ABE scheme.

A Framework and Compact Constructions for Non-monotonic Attribute-Based Encryption.
TL;DR: The first non-monotonic attribute-based encryption scheme with compact parameters was proposed in this paper, where the ciphertext overhead only consists of two group elements and this is the shortest in the literature.
