Deformation of box-sectional structures during torsion with bending
Magazine of Civil EngineeringThe article is devoted to the problem of complex stress state of reinforced concrete under the action of torsion with bending, taking into account axial and transverse forces. The existing calculation models remain imperfect, despite a significant number

Toward Mechanical Intelligence in Robotics
Advanced Robotics Research, EarlyView.Robots can use their physical bodies to perform functions usually assigned to electronic sensors and controllers. This perspective defines mechanical intelligence through three core operations: filtering inputs, routing mechanical signals, and switching between states.

Robotics in Ionizing Radiation Environments: Vulnerabilities, Hardening, and Future Directions
Advanced Robotics Research, EarlyView.Radiation exposure causes cumulative degradation in robotic sensors, actuators, and electronic logic, often leading to undetected failures. This study maps component vulnerabilities, evaluates hardening and shielding strategies, and identifies testing gaps that must be addressed to enable next‐generation radiation‐tolerant robotic systems.

DEVELOPMENT OF HIERARCHICAL REINFORCED CONCRETE ELEMENTS
Doboku Gakkai Ronbunshuu A, 2009 コンクリート床版などを有する複合橋梁構造物の全体解析を効率的に行うためのハイアラーキRC要素を提案する．本要素は，ハイアラーキ六面体ソリッド要素に鉄筋やPC鋼材などの補強鋼材を埋め込んだ要素であり，ソリッド要素の一般化変位を補強鋼材の変位関数に用いてソリッド要素内で補強鋼材の変位を級数展開することにより，補強鋼材配置位置での要素分割を必要としない．さらに，ソリッド要素内に多数の鉄筋を任意の方向に配置することができる．また，ケーブル要素を曲線鋼材に用いてプレストレスを導入することができる．

Advanced Science, EarlyView.Functional amyloid conversion of the translation regulator CPEB3 is essential for long‐term memory persistence. This study demonstrates that targeting this molecular switch with the anti‐amyloidogenic peptide QBP1 selectively blocks CPEB3 fibrillation without disrupting phase separation.

Helix Alignment, Chevrons, and Edge Dislocations in Twist‐Bend Ferroelectric Nematics
Advanced Science, EarlyView.The recently discovered twist‐bend ferroelectric nematic (NTBF) is the new member of the multiferroic family, representing a fluid with an oblique helicoidal (heliconical) periodic structure of spontaneous electric polarization. The work presents a thorough exploration of the material properties of this phase, how the periodic modulation of ...

Crack Propagation Law of Reinforced Concrete Beams
Applied SciencesDuring the process of the shear and bending failure of reinforced concrete beams, the cracks generated on the side of the beam are mostly type I–II composite cracks. Considering the material nonlinearity and geometric irregularity of reinforced concrete,
