Structural instability impairs function of the UDP‐xylose synthase 1 Ile181Asn variant associated with short‐stature genetic syndrome in humans

open access: yesFEBS Letters, EarlyView.
The Ile181Asn variant of human UDP‐xylose synthase (hUXS1), associated with a short‐stature genetic syndrome, has previously been reported as inactive. Our findings demonstrate that Ile181Asn‐hUXS1 retains catalytic activity similar to the wild‐type but exhibits reduced stability, a looser oligomeric state, and an increased tendency to precipitate ...

An optimal transformer differential protection method based on zero-sequence differential current characteristics

open access: yesZhejiang dianli
When current transformers are not installed on the delta winding of a wye-delta transformer, the differential protection must utilize currents measured outside the delta winding to calculate the differential current.

Pilot Protection Based on Zero-Sequence Current Resistance-Capacitance Component for Large-Scale Inverter-Interfaced Power Stations

open access: yes, 2022
At present, zero-sequence current protection is generally used as the main protection for single-phase ground faults in resistance-grounded inverter power stations.

Analysis of two-phase operation characteristics of a flexible low-frequency transmission system

open access: yesZhejiang dianli, 2022
The two-phase operation mode of a flexible low-frequency transmission system is based on the M3C (modular multilevel matrix converter). This paper establishes a complex sequence network for the low-frequency system to analyze the steady-state operation ...

Calpain small subunit homodimerization is robust and calcium‐independent

open access: yesFEBS Letters, EarlyView.
Calpains dimerize via penta‐EF‐hand (PEF) domains. Using single‐molecule force spectroscopy, we measured the strength and kinetics of PEF–PEF homodimer binding. The interaction is robust, shows a transient conformational step before dissociation, and remains largely insensitive to Ca2+.

Research on fault line selection method of mine power network

open access: yesGong-kuang zidonghua, 2018
In view of characteristics of DC component of transient zero-sequence current in fault lines is larger than that of normal lines when additional DC source system of mine power network occurrs single-phase earth fault, a fault line selection method of ...

An improved Hausdorff distance method for locating single phase to ground fault in neutral non‐effectively grounded system

open access: yesIET Generation, Transmission & Distribution, 2021
Neutral non‐effectively grounded mode is widely used in medium‐voltage distribution networks in China. When a single‐phase grounding fault occurs in distribution networks, abundant transient signals will be generated.

INSTABILITY PROBLEM OF CONVENTIONAL TRANSFORMER DIFFERENTIAL PROTECTION-APPLICATION OF ZERO SEQUENCE CURRENT TRAP

open access: yes, 2013
Zero sequence component of current usually causes instability of the differential protection. It enters circuits through earthed terminals. The traditional way of solving the problem in differential schemes is by connecting the interposing current ...

Random partitions in statistical mechanics [PDF]

open access: yes, 2014
We consider a family of distributions on spatial random partitions that provide a coupling between different models of interest: the ideal Bose gas; the zero-range process; particle clustering; and spatial permutations.

The ubiquitin ligase RNF115 is required for the clearance of damaged lysosomes

open access: yesFEBS Letters, EarlyView.
Upon lysosomal rupture, an E3 ubiquitin ligase RNF115 translocates from the cytosol to the damaged lysosomal membrane. Moreover, RNF115 depletion impairs the clearance of damaged lysosomes, identifying it as a key regulator of lysosomal quality control.
