Performance of the XL-Calibur hard X-ray telescope before and after the 2022 stratospheric flight

Haruki Kuramoto, Hironori Matsumoto, Hiromitsu Takahashi, Yoshitomo Maeda et autres

We report on the performance of the hard X-ray telescope (HXT) onboard the XL-Calibur balloon-borne mission, before and after its 2022 long duration balloon (LDB) flight. XL-Calibur aims to achieve high-sensitivity hard X-ray polarization observations, with the HXT providing the large effective …

A computed tomography observation of the Unzen lava reveals the frequent existence of vesicles and crystals in proximity

Konan Saito, Masato Hoshino, Akio Goto, Atsuko Namiki

The dynamics of eruptions are controlled by volcanic outgassing through interconnected bubble networks. The question of whether frameworks formed by crystals facilitate gas escape remains unresolved, with the relative spatial arrangements of bubbles and crystals yet to be elucidated. In the presentation, …

Evaluation of crack propagation in high-concentration Al-Mg-Si alloys using synchrotron X-ray imaging

Keitaro Horikawa, Masato Hoshino, Kentaro UESUGI

Dynamic fracture behavior of Al-Mg-Si-based alloys was monitored through synchrotron X-ray computed microtomography and X-ray high-speed radiography during the tensile test. We have succeeded in measuring the internal crack propagation rate by X-ray radiography with high-speed microscopy. It was revealed that the …

Effects of microgravity on the three-dimensional morphology of rhizoids in Physcomitrium patens

Yagihara Naoki, Wakabayashi Takahisa, Ryohei Yamaura, Daisuke Tamaoki et autres

Abstract Rooting systems of plants perceive environmental stimuli and flexibly regulate their growth. Therefore, understanding stimulus perception and response mechanisms is essential for optimizing cultivation. During the transition from aquatic to terrestrial environments, land plants have acquired mechanisms to adapt to gravitational …

Effect of Initial Relative Density on Liquid-Phase Sintering Behaviors of Al Powder Using Al–Cu Eutectic Alloy Aid: In Situ Observations Using Tomography and Microscopy

Ryotaro Kusunoki, T. Higaki, Asuka Suzuki, Makoto Kobashi et autres

Aluminum (Al) powder with low sinterability is difficult to use in binder jetting (BJT) additive manufacturing, which involves sintering a metal powder after forming a green body. A liquid-phase sintering process for Al powder using Al–Cu eutectic alloy powder as a sintering …

A computed tomography observation of the Unzen lava reveals the frequent existence of vesicles and crystals in proximity

Masato Hoshino, Akio Goto, Atsuko Namiki

Volcanic outgassing through interconnected bubble networks controls eruption dynamics. Frameworks formed by crystals may facilitate gas escape, but the relative spatial arrangements of bubbles and crystals remain overlooked. We conducted multi-resolution X-ray computed tomography (CT) imaging to examine vesicle-crystal spatial relationships in …

CCDC141 is a Connectin/Titin and Nesprin-1 binding protein that adapts cardiomyocytes to mechanical stress

Akira Hanashima, Misaki Kimoto, Yoshihiro Ujihara, Ken Hashimoto et autres

The heart adapts to mechanical stresses such as hypertension, yet the underlying mechanisms remain poorly understood. We identify CCDC141 as a mechanoadaptive factor in cardiomyocytes. CCDC141 interacts with the sarcomeric connectin/titin filament system and the nuclear envelope protein nesprin-1, and localizes to …

Eph-ephrin signaling affects lens growth and shape, nucleus size, and gradient refractive index in adult mice

Gryffin M. Flowers, Kehao Wang, Masato Hoshino, Kentaro Uesugi et autres

Purpose The function of the eye lens, to fine focus light from different distances onto the retina to form a clear image, relies on tissue biomechanical properties, refractive index, shape, and transparency. Increased lens stiffness with age, especially of the center or …
