Morphological evolution and diversity of pectoral fin skeletons in teleosts

Yoshitaka Tanaka, Hiroki Miura, Koji Tamura & Gembu Abe
Abstract The Teleostei class has the most species of the fishes. Members of this group have pectoral fins, enabling refined movements in the water. Although teleosts live in a diverse set of environments, the skeletal pattern of pectoral fins in teleosts is considered to show little morphological variability. Here, in order to elucidate variations in pectoral fin skeletons and to identify their evolutionary processes, we compared the pectoral fin skeletons from 27 species of teleosts....

Lithological structure of western Pacific lithosphere reconstructed from mantle xenoliths in a petit-spot volcano

Kazuto Mikuni, Naoto Hirano, Norikatsu Akizawa, Junji Yamamoto, Shiki Machida, Akihiro Tamura, Yuuki Hagiwara & Tomoaki Morishita
Abstract The lithospheric mantle, formed at the mid-ocean ridge as a residue of crustal production, comprises theoretically depleted peridotite, but more fertile components (e.g., lherzolite and pyroxenite) have been reported, creating an enigmatic picture of the lithosphere. The oceanic lithosphere has also been found to be locally modified by intraplate magmatism as proposed from geochemistry of mantle xenolith. Petit-spot xenoliths are particularly notable as direct evidence of old lithospheric mantle and expected to retain essential...

Gamma-secretase inhibitor does not induce cytotoxicity in adult T-cell leukemia cell lines despite NOTCH1 expression

Shinsuke Suzuki, Sawako Hourai, Kimiharu Uozumi, Yuichirou Uchida, Makoto Yoshimitsu, Hachiman Miho, Naomichi Arima, Shin-ichi Ueno & Kenji Ishitsuka
Abstract Background Activated mutations in NOTCH1 are drivers of T-cell type acute lymphoblastic leukemia/lymphoma. The γ-secretase inhibitor (GSI), which suppresses the function of NOTCH1, is expected to be a molecular-targeted agent. NOTCH1 is also expressed in other malignant neoplasms. We aimed to determine the function of NOTCH1 expression and the effects of GSI on adult T-cell leukemia/lymphoma (ATL) caused by long-term human T-cell leukemia virus type I (HTLV-1) infection. Methods We analyzed the expression of...

Continuous estimation of coseismic and early postseismic slip phenomena via the GNSS carrier phase to fault slip approach: a case study of the 2011 Tohoku-Oki sequence

Yusuke Tanaka, Yusaku Ohta & Shin’ichi Miyazaki
Abstract The transition process from coseismic to early postseismic phenomena within a half-day remains a significant topic for understanding the slip budget and friction properties of the fault. However, the investigation of this phase has undergone limited advancement. This is mainly due to the lack of precision pertaining to the Global Navigation Satellite System (GNSS) analysis caused by difficulty of separation between fault slip and other unknown parameters such as tropospheric delay. Therefore, we propose...

Do coagulation or fibrinolysis reflect the disease condition in patients with soft tissue sarcoma?

Kunihiro Asanuma, Tomoki Nakamura, Takayuki Okamoto, Tomohito Hagi, Kouji Kita, Koichi Nakamura, Yumi Matsuyama, Keisuke Yoshida, Yumiko Asanuma & Akihiro Sudo
Abstract Background Coagulation and fibrinolysis are distinct processes that are highly correlated. Cells control coagulation and fibrinolysis by expression of tissue factor and urokinase-type plasminogen activator receptor on their surface. Tumor cells express these proteins, adjust their microenvironment and induce tumor exacerbation. We hypothesized that the expression of plasma markers for coagulation and fibrinolysis in patients with soft tissue sarcomas (STSs) was dependent on the level of tumor malignancy. To elucidate which markers are predictive...

Analysis of the risk of theft from vehicle crime in Kyoto, Japan using environmental indicators of streetscapes

Hiroki M. Adachi & Tomoki Nakaya
Abstract With the advent of spatial analysis, the importance of analyzing crime patterns based on location has become more apparent. Previous studies have advanced our understanding of the factors associated with crime concentration in street networks. However, it has recently become possible to assess the factors associated with crime at even finer spatial scales of streetscapes, such as the existence of greenery or walls, owing to the availability of streetscape image data and progress in...

Tensile strained direct bandgap GeSn microbridges enabled in GeSn-on-insulator substrates with residual tensile strain

Daniel Burt, Lin Zhang, Yongduck Jung, Hyo-Jun Joo, Youngmin Kim, Melvina Chen, Bongkwon Son, WJ FAN, Zoran Ikonic & Chuan Seng Tan
Tensile strained GeSn alloys are being extensively explored as a potential gain medium for lasers compatible with complementary metal-oxide-semiconductor (CMOS) technology. Despite having achieved drastically improved lasing characteristics by harnessing tensile strain, the current methods of introducing a sizeable tensile strain into GeSn lasers require complex fabrication processes, thus reducing the viability of the lasers for practical applications. The geometric strain amplification is a simple technique that can concentrate residual and small tensile strain into...
