Studying and simulating transformer configuration to improve power quality

Ingeniería e Investigación, 2011
This paper presents a study and simulation of transformer configurations to improve power quality; it provides theoretical support based on the expansion of the Fourier series and analysis of symmetrical components.

Error Correction in Vergence Eye Movements: Evidence Supporting Hering’s Law

Journal of Eye Movement Research, 2012
In pure symmetrical vergence eye movements, a fusion initiating component quickly brings the eyes close to the desired position. A small error usually remains after this response which must be corrected to attain the small final vergence error (i.e ...

Krull symmetric noetherian rings and their homogeneous components

Journal of Pure and Applied Algebra, 1986
A noetherian ring R is Krull symmetric if for every pair of ideals \(T\subseteq S\) of R the right and left Krull dimensions of S/T are equal. A module M is K-homogeneous if all non-zero submodules of M have the same Krull dimension. In general, the sum of two homogeneous left ideals of the same Krull dimension need not be homogeneous. However, if R is

Analysing the significance of small conformational changes and low occupancy states in serial crystallographic data

FEBS Open Bio, EarlyView.
This protocol paper outlines methods to establish the success of a time‐resolved serial crystallographic experiment, by means of statistical analysis of timepoint data in reciprocal space and models in real space. We show how to amplify the signal from excited states to visualise structural changes in successful experiments.

UiO‐66 metal–organic frameworks in biomedicine: From structural tunability to bioimaging, photodiagnostics, and photodynamic cancer therapy

FEBS Open Bio, EarlyView.
UiO‐66(Zr) metal–organic frameworks are chemically stable, biocompatible, and highly tunable nanomaterials. Their modular structure enables controlled drug delivery, multimodal bioimaging, and light‐activated photodynamic therapy, supporting integrated diagnostic and therapeutic (theranostic) applications in cancer and biomedical research.

EMT-Based Sequence Analysis of a Converter-Dominated Microgrid Under Fault and Load Disturbances: Case Study of the NELHA Microgrid

IEEE Access
Converter-dominated microgrids exhibit dynamic behaviors during faults and disturbances that differ fundamentally from those of synchronous-machine–dominated systems.

Hyperactive ice‐binding proteins stabilize cell membranes and improve resistance to dehydration stress in Caenorhabditis elegans

FEBS Open Bio, EarlyView.
TisIBP8, a fungal‐derived hyperactive ice‐binding protein, helps Caenorhabditis elegans survive dehydration. It localizes near cell membranes, reduces cell damage, and helps maintain membrane structure during drying. These results suggest that ice‐binding proteins can protect cells from dehydration stress as well as freezing stress.

An Invertible Extended Sequence Transform for Untransposed Three-Phase Overhead Lines

Energies
The classical Fortescue symmetrical-component transform remains fully invertible as a similarity transform when the complete sequence-domain matrix is retained.

Structural studies and functional engineering of NanX: an anhydro‐sialic acid transporter from Escherichia coli

FEBS Open Bio, EarlyView.
Biophysical characterisation shows that NanX, a membrane transport protein from the major facilitator superfamily (MFS), forms both monomers and dimers after purification. AlphaFold modelling and substrate docking provide information on residues likely involved in substrate recognition for NanX and another MFS member, NanT.

Implementation of three-phase transformer model in radial load-flow analysis

Ain Shams Engineering Journal, 2013
This paper presents an efficient approach for developing three-phase transformer admittance matrices in the radial power-flow analysis. The proposed transformer model overcomes the singularity problem of the nodal admittance submatrices of ungrounded ...
