Insulin Dosing Is Associated With Cardiac Sympathetic Predominance Independent of Glycemic Profiles in Type 1 Diabetes Under Free-Living Conditions

Aki Kondo, Kaori Ikeda, Shizuka Kaneko, Shinichi Harashima et autres

While insulin activates the sympathetic nervous system in experimental settings, whether therapeutic insulin administration is associated with cardiac sympathetic predominance under free-living conditions remains unclear. This prospective observational study investigated the association between insulin dosing and cardiac autonomic balance in adults with …

Phase-controlled null-space expansion for analog beamforming massive MIMO in high-mobility scenarios

Yuta Tsunoda, Mitsuki Muroi, Yuki Sasaki, Chun-Hsiang Huang et autres

Abstract This paper proposes a novel null-space expansion (NSE) scheme based on phase-only control to exploit the degrees of freedom of massive antenna elements even in analog beamformers. Downlink multi-user Multiple-Input Multiple-Output (MIMO) spatial multiplexing is performed through precoding in the baseband …

Chaotropic Surface Arginine Correlates With Protein Corona Formation on Anti‐Fouling Biomaterial Surfaces: A Quantitative Proteomics and Protein Structure Study

Ayano Nomura, Guanghao Hu, Ang Art Wei Yao, Chisato Komura et autres

ABSTRACT The protein corona determines the biocompatibility of medical devices, yet predicting its composition on anti‐fouling surfaces remains challenging. We performed quantitative proteomic analysis (nano LC‐MS/MS) of proteins adsorbed from human serum onto six model organic surfaces. Identifying over 200 proteins per …

FEM-based thermal deformation analysis of large Fine Cordierite mirrors induced by CTE inhomogeneity

Jun Kajihara, Yuji Ikeda, Koki Isoyama, Hidehito Himeno et autres

Fine Cordierite® has attracted attention as a candidate material for large astronomical mirrors because it combines a low coefficient of thermal expansion (CTE) with high Young’s modulus and high thermal conductivity compared to low-expansion glass and glass ceramics. Isoyama et al. (2024) …

Efficacy of multi-layered human iPS cell-derived cardiovascular cell sheets in a pacing-induced canine dilated cardiomyopathy model

Yu Shimoyama, Kenji Kakuta, Kiho Araki, Hyoe Komae et autres

BACKGROUND: Dilated cardiomyopathy (DCM) is a progressive, intractable disease that leads to heart failure. Heart transplantation is the only curative treatment; however, access is limited by donor scarcity. Induced pluripotent stem cell (iPSC)-based therapies are attracting attention for DCM, but suitable large-animal …

Novel open fault detection of bypass circuit with IR camera-removal of dynamic disturbance by moving clouds

Shogo Nishikawa

One of the most popular existing technology for finding open bypass circuit to prevent hotspot is the measurement of surface temperature with an IR camera. However, this solution has defects. For example, thermal image is affected by the reflection of surrounding structure …

Quantum fluctuation-driven transport crossover between two liquid states in distinguishable helium-4

Mika Tanabe, Momoko Tsujimoto, Kenichi Kinugawa

We show the emergence of a quantum fluctuation-driven transport crossover between two liquid states in distinguishable helium-4 obeying Boltzmann statistics, in the absence of atomic exchange. Using path integral centroid molecular dynamics simulations over 0.1-3.3 K and 1-60 bar, we investigate the …

Monolithic Magneto-Optical Mach-Zehnder Isolator Using Laser-Annealed Iron Garnet on a Silicon Waveguide

Tomoya Sugita, Reona Motoji, Yuki Yoshihara, Dan Maeda et autres

Stable silicon photonic circuits require monolithically integrated optical isolators based on magneto-optical garnet. However, crystallizing the garnet by conventional furnace annealing exposes the entire chip to high temperature and degrades the silicon waveguides and the metal electrodes. Here we avoid this degradation …

Evaluation of diffraction-limited performance of a large optical antenna for cislunar optical communication system

Takaki Nakagawa, Naoto Iida, Hiroyuki Hori, Eiji Suzuki et autres

Future Earth–Moon optical communication requires a telescope that can maintain diffraction-limited performance despite severe thermal fluctuations, radiation, and launch loads. Fine Cordierite®, developed by Kyocera, offers ultra-low CTE, high stiffness, radiation resistance, and machinability for complex structures, enabling monolithic and highly athermal …
