On generalized injective modules and almost injective modules
Autor: Hayate Fuchigami, Yosuke Kuratomi, Yoshiharu Shibata
Publikováno v: Journal of Algebra and Its Applications.
A module [Formula: see text] is called [Formula: see text]-almost-invariant for a module [Formula: see text] if, for any homomorphism [Formula: see text], either [Formula: see text], or there exist nonzero direct summands [Formula: see text] of [Form

Factor square full modules
Autor: Yosuke Kuratomi, Isao Kikumasa, Yoshiharu Shibata
Publikováno v: Communications in Algebra. 49:2326-2336
In this paper, we first introduce the concept of “factor-square-full” modules defined as follows: For any proper submodule X of M, there exist a proper submodule Y of M with X⊆Y and an epimorphism ...

On dual of square free modules
Autor: Yoshiharu Shibata, Derya Keskin Tütüncü, Isao Kikumasa, Yosuke Kuratomi
Publikováno v: Communications in Algebra. 46:3365-3376
A module M is said to be square free if whenever its submodule is isomorphic to N2 = N⊕N for some module N, then N = 0. Dually, a module M is said to be d-square free (dual square free) if whenever its factor module is isomorphic to N2 for some mod

On image summand coinvariant modules and kernel summand invariant modules
Autor: Derya Keskin Tütüncü, Yoshiharu Shibata, Yosuke Kuratomi
Publikováno v: Volume: 43, Issue: 3 1456-1473
Turkish Journal of Mathematics
In this paper we introduce the concept of im-summand coinvariance and im-small coinvariance; that is, a module $M$ over a right perfect ring is said to be im-summand (im-small) coinvariant if, for any endomorphism $\varphi$ of $P$ such that ${\rm Im}

Interoperable and diligent body area networks over IEEE802.15.6 for real-time monitoring
Autor: Kenichi Takizawa, Isami Kaneda, Osamu Tochikubo, Masahiro Kuroda, Yoshiharu Shibata
Publikováno v: EMBC
Currently, there are no standardization efforts to define interfaces and verify interoperability among implementations for body area networks (BANs) on IEEE802.15.6. A BAN consists of small and lightweight sensors, such as the ring-type SpO2 sensor,

Insular Variation of the Japanese Hare (Lepus brachyurus) on the Oki Islands, Japan
Autor: Hirofumi Hirakawa, Yoshiharu Shibata, Tsutomu Kuwahata, Eiichi Yamada
Publikováno v: Journal of Mammalogy. 73:672-679
Geographic comparisons of 25 skull and four external characters of the Japanese hare ( Lepus brachyurus ) revealed that hares from Nishinoshima and Dogo of the Oki Islands and hares from Shimane Prefecture on mainland Honshu are distinct. The Oki Isl
