Investigation of Magnetic Force Hysteresis in Electromechanical Actuators

Chemical Engineering &Technology, Volume 46, Issue 1, Page 158-166, January 2023., 2023
An approach for the phenomenological modeling of force hysteresis, which is characterized by a very simple parameterization and a relatively low error, is presented. The real‐time model considers the influence of hysteresis effects of the iron circuit, friction, variable stroke, and eddy currents on the generated force.

RAB8A GTPase regulates spindle migration and Golgi apparatus distribution via ROCK‐mediated actin assembly in mouse oocyte meiosis†

Biology of Reproduction, 2018
Actin filaments are widely involved in multiple cellular processes in oocyte meiosis, such as spindle migration and polar body extrusion. The actin nucleators like Arp2/3 complex and formins are the most recognized molecules for actin assembly in oocytes.

Thin carbon–polypyrrole composite materials for supercapacitor electrodes by novel bipolar electrochemical setup

Electrochemical Science Advances, Volume 2, Issue 6, December 2022., 2022
Abstract A simple approach to mitigate the use of high voltages on thin bipolar electrodes is described here for the first time. The method involves stacking the desired thin conductor onto a thicker one, thereby creating a pseudo‐single electrode whose width is the sum of the two.

3D hierarchical porous carbon foams as high‐performance free‐standing anodes for microbial fuel cells

EcoMat, Volume 5, Issue 1, January 2023., 2023
The iron‐based MOF nanoparticles/seitan derived hierarchical porous carbon foams (HPCF) provide marcopores for exoelectrogens enrichment and growth, as well as mesopores with N heteroatoms and iron ions for promoting extracellular electron transfer mainly via bound flavin pathway. MFCs equipped by HPCF anode achieve a power density of 11.21 W m−3 and a

Inactivation of RB1, CDKN2A, and TP53 have distinct effects on genomic stability at side‐by‐side comparison in karyotypically normal cells

Genes, Chromosomes and Cancer, Volume 62, Issue 2, Page 93-100, February 2023., 2023
Abstract Chromosomal instability is a common feature in malignant tumors. Previous studies have indicated that inactivation of the classical tumor suppressor genes RB1, CDKN2A, and TP53 may contribute to chromosomal aberrations in cancer by disrupting different aspects of the cell cycle and DNA damage checkpoint machinery.

Soman induces endoplasmic reticulum stress and apoptosis of cerebral organoids via the GRP78‐ATF6‐CHOP signaling pathway

FEBS Open Bio, EarlyView.
Cerebral organoids were employed as a novel model to explore the neurotoxicity of soman. Soman inhibited acetylcholinesterase activity, increased cell apoptosis and upregulated endoplasmic reticulum (ER) stress markers glucose‐regulated protein 78 (GRP78), activating transcription factor 6 (ATF6) and C/EBP homologous protein (CHOP).

Survival and failure modes of the Compress® spindle and expandable distal femur endoprosthesis among pediatric patients: A multi‐institutional study

Journal of Surgical Oncology, Volume 127, Issue 1, Page 148-158, January 2023., 2023
Abstract Background Expandable endoprostheses can be used to equalize limb length for pediatric patients requiring reconstruction following large bony oncologic resections. Outcomes of the Compress® Compliant Pre‐Stress (CPS) spindle paired with an Orthopedic Salvage System expandable distal femur endoprosthesis have not been reported.

Distinct Network Morphologies from In Situ Polymerization of Microtubules in Giant Polymer‐Lipid Hybrid Vesicles

Advanced Biology, EarlyView.
The successful in situ polymerization of microtubules in giant polymer‐lipid hybrid vesicles is illustrated. The microtubules formed in the giant hybrid vesicles exhibit different morphologies including lumenal network formation and membrane association. Abstract Creating artificial cells with a dynamic cytoskeleton, akin to those in living cells, is a

Evaluation of the efficacy of modal analysis in predicting the pullout strength of fixation bone screws

JOR SPINE, Volume 5, Issue 4, December 2022., 2022
We evaluated the efficacy of a novel method in predicting the pullout strength of bone screws. The analysis showed that the pullout strength is highly affected by the size of the pilot hole. The nondestructive method can be used to predict the pullout strength of the bone screws.
