Residual tail twisting in ascidian larvae is stabilized by asymmetric myofibrils that resist bilateral symmetry restoration

open access: yesFEBS 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 ...

Research on a small-signal stability criterion for MMC controller

open access: yesZhejiang dianli
High voltage direct current (HVDC) transmission based on modular multilevel converter (MMC) is widely used in large-scale renewable energy delivery. However, the lagged inertia of MMC controllers may undermine the small-signal stability.

Mitigating the impacts of geomagnetic disturbances on the small signal stability

open access: yesInternational Journal of Electrical Power & Energy Systems
Geomagnetically induced currents (GICs) caused by geomagnetic disturbances (GMDs) flow through the transformers, which lead to the increase of reactive power loss (QGIC). As reactive loads added to the system, QGIC causes the change of power flow distribution, which connects GMDs with small signal stability.

The human gut microbiome across the life course

open access: yesFEBS Letters, EarlyView.
Despite significant individual variation and continuous change throughout life, the human gut microbiome follows some life stage‐specific trends. This article provides a brief overview of how gut microbiome composition shifts across different phases of life. Created in BioRender. Özkurt, E. (2026) https://BioRender.com/8q4nrnc.

Small Signal Modeling and Stability Analysis of Modular Multilevel Converter Based on Harmonic State-Space Model

open access: yesEnergies, 2020
The stability of Modular multilevel converter (MMC) itself is the premise of analyzing the stability of MMC cascading with other cells, so this paper addressed the small-signal stability of MMC with dc voltage control mode which is the common operation ...

Rab14 regulates the transport of human papillomavirus to the trans‐Golgi network for infectious cell entry

open access: yesFEBS Letters, EarlyView.
This study reveals that the small GTPase Rab14 is necessary for human papillomavirus (HPV) infection and plays an essential role in the transport of virions to the trans‐Golgi network (TGN). HPV in the early endosome (EE), which harbors GTP‐bound Rab14, is transported to the TGN through the switch of Rab14 from its GTP‐bound to GDP‐bound form.

Optimal Power Flow With Regression-Based Small-Signal Stability Constraints

open access: yesIEEE Access
In modern power systems, with a growing integration of inverter-based resources, small-signal stability is becoming increasingly important. However, current practice in operation and planning studies is based on solving optimization problems, mainly ...

Small-Signal Stability Analysis and Optimal Parameters Design of Microgrid Clusters

open access: yesIEEE Access, 2019
The two-layer distributed control architecture, including the microgrid (MG) control layer and MG cluster (MGC) control layer, can be used for interconnecting multiple MGs to form the MGC. However, the coupling among multiple elements and the interaction

On the stability and control of discrete linear systems with clock synchronization errors

open access: yes, 2011
This paper considers discrete linear time-invariant systems that can be decomposed into subsystems whose states are synchronized by a common clock whose signal reaches them with delays.

Salmonella lipopolysaccharide‐containing supported lipid bilayers as platforms to study bacteriophage interactions

open access: yesFEBS Letters, EarlyView.
We present robust protocols for the preparation of supported lipid bilayers (SLBs) incorporating either Salmonella smooth LPS or outer membrane vesicles (OMVs). We use a combination of quartz crystal microbalance with dissipation (QCM‐D) and fluorescence microscopy to both characterize the SLBs of various compositions and to probe their interactions ...
