Diversity and complexity in neural organoids
FEBS Letters, EarlyView.Neural organoid research aims to expand genetic diversity on one side and increase tissue complexity on the other. Chimeroids integrate multiple donor genomes within single organoids. Self‐organising multi‐identity organoids, exogenous cell seeding, or enforced assembly of region‐specific organoids contribute to tissue complexity.

Dizhen xuebao基于2010年10月至2022年7月期间长宁地区MS≥3.0地震事件，采用CAP全波形反演获取震源机制解，并结合阻尼最小二乘法反演该区域应力场的时空变化特征；同时利用多台联合反演方法提取震源参数，结合b值演化分析地震活动性演变过程。结果表明：长宁地区地震以逆冲型和走滑型为主，震源深度浅，地震活动集中分布于华蓥山断裂带西侧，最大主应力方向为WNW－ESE，整体应力场稳定，但在2019年MS6.0强震后出现短期扰动；震源参数（应力降、拐角频率、震源半径）与震级呈显著相关性，应力降均值为7.94 MPa ...

, 1990 Program FMSI inverts observations of slip directions on fault planes of known orientation in order to determine the best-fitting four-parameter stress tensor, defined by three principal stress directions and R=(σ2 − σ1)/(σ3 − σ1), and the associated ...

Hyperosmotic stress induces PARP1‐mediated HPF1‐dependent mono(ADP‐ribosyl)ation
FEBS Letters, EarlyView.Sorbitol‐induced hyperosmotic stress rapidly induces reversible mono(ADP‐ribosyl)ation (MARylation) on PARP1 without the signs of genotoxic signaling. We show that PARP1 autoMARylation is HPF1 dependent and forms hydroxylamine‐resistant O‐glycosidic linkages.

Dizhen xuebao基于全球质心矩张量GCMT资料，搜集整理了1991—2005年新疆柯坪地区中强地震的震源机制解；利用新疆地震台网2004—2024年宽频带波形数据，采用CAP方法补充计算了区域内MS≥3.5地震的震源机制解；采用区域应力张量阻尼方法（MSATSI）反演了柯坪地区应力空间分布，探讨了其应力场分区特征。结果表明，柯坪地区地震事件的震源机制解以逆断型为主，震源深度集中在5—30 km范围内，其中西部地区地震震源深度由南向北逐渐增加；东部地区地震事件以2024年乌什MS7.1地震序列为主，震源深度主要集中在5 ...

Focal Mechanism Computation by Means of Fourier Analysis
, 1986 Fast computation of focal mechanism is achieved with the use of Fourier analysis for a P.wave polarity distribution on a focal sphere. If the focal sphere is rotated so as to give a vertical null axis, the polarity becomes a function of azimuth only. Let

FEBS Letters, EarlyView.Plasma membranes contain dynamic nanoscale domains that organize lipids and receptors. Because viruses operate at similar scales, this architecture shapes early infection steps, including attachment, receptor engagement, and entry. Using influenza A virus and HIV‐1 as examples, we highlight how receptor nanoclusters, multivalent glycan interactions ...

Focal Mechanism Determination from S Wave Observations of Different Qualit
, 1970 A least squares method is derived for the focal mechanism determination from S wave observations (polarization angles) of different quality. Some considerations are made on how to determine a weight appropriate to each observation.As one of numerical ...

FEBS Letters, EarlyView.Embryo‐like structures (stembryos) are an innovative tool, but they are hindered by experimental variability and limited developmental potential. DNA methylation is crucial for mammalian development, but its status in stembryo models is poorly characterized.

FEBS Letters, EarlyView.Ascidian Ciona larvae initially show strong clockwise tail twisting, which is largely corrected during development. However, a small residual twist remains. This study shows that organized helical myofibrils in tail muscles mechanically stabilize this residual asymmetry, preventing complete restoration of bilateral symmetry and revealing how embryos ...
