    Study on the Full‐Cycle Stress Evolution Law and Reasonable Size of Isolated Coal Pillar by Xiao‐Xiang Wei, Qing‐Long Yun, Jing Wu, Xiao‐He Wang, Yin‐Wei Wang

    Published 2025-01-01
    “…The results show that the vertical stress and maximum principal stress increase correspondingly with the decrease of the protective coal pillar size under both stages, and the minimum value of the minimum principal stress occurs on the 8 m protective coal pillar; The values of the principal stress ratio and the principal stress deflection angle do not differ greatly in the protection of the coal pillar, and the fluctuation of the values is mainly concentrated in the vicinity of the back‐mining roadway; The second invariant of bias stress (J2) is mainly concentrated in the protective coal pillar near the side of the extraction zone, when the size of the protective coal pillar is reduced to 10 m, the J2 on the side of the extraction zone and the J2 on the side of the roadway are connected, and the whole protective coal pillar is under the influence of J2, which is basically the same as the damage pattern of the plastic zone; Based on the formula of limit balance theory to calculate the elastic core width of different sizes of protective coal pillars, and combined with the results of numerical simulation analysis, it finally concluded that the reasonable size of the protective coal pillar of this isolated island working face is 15 m.…”

    Neural activity responsiveness by maturation of inhibition underlying critical period plasticity by Ibuki Matsumoto, Sou Nobukawa, Sou Nobukawa, Sou Nobukawa, Sou Nobukawa, Takashi Kanamaru, Takashi Kanamaru, Yusuke Sakemi, Yusuke Sakemi, Nina Sviridova, Nina Sviridova, Tomoki Kurikawa, Nobuhiko Wagatsuma, Kazuyuki Aihara, Kazuyuki Aihara

    Published 2025-01-01
    “…Accumulating evidence indicates that the maturation of inhibitory circuits, such as gamma-aminobutyric acid and parvalbumin-positive interneurons, plays a crucial role in CPs and contributes to generating gamma oscillations. A previous theory of the CP mechanism suggested that the maturation of inhibition suppresses internally driven spontaneous activity and enables synaptic plasticity to respond to external stimuli. …”
