Electronic error compensation of a current transformer

Electronics Letters, 1971
A scheme is presented employing two precision resistors and an electronic amplifier for reducing the ratio and phase-angle errors in a current transformer. The amplifier supplies only the error current. The proposed arrangement facilitates the adaptability of inexpensive low ampere-turn c.t.s for calibration work in the laboratory.

CCDC80 suppresses high‐grade serous ovarian cancer migration via negative regulation of B7‐H3

Molecular Oncology, EarlyView.
PAX8 is a lineage‐specific master regulator of transcription in high‐grade serous ovarian cancer (HGSC) progression. We show for the first time that PAX8 facilitates proliferation and metastasis by repressing the cell autonomous tumor suppressor CCDC80 and inducing B7‐H3 expression.

Research on error analysis and calibration technology of current transformers under the influence of DC bias magnetization

Diance yu yibiao
Under the influence of DC bias, the iron core of the current transformer is prone to saturation, causing the ratio error to shift towards negative direction and the phase error to shift towards positive direction, resulting in measurement inaccuracy ...

KDM7A and KDM1A inhibition suppresses tumour promoting pathways in prostate cancer

Molecular Oncology, EarlyView.
Treatment resistance is a major challenge for patients with advanced prostate cancer. This study examined an alternative approach to target the major prostate cancer‐promoting pathway by targeting epigenetic factors, whose levels are higher in tumours.

Longitudinal circulating tumor DNA profiling in patients with advanced endometrial cancer using an off‐the‐shelf targeted NGS panel

Molecular Oncology, EarlyView.
Intratumour heterogeneity complicates precision management of advanced endometrial cancer. Circulating tumor DNA (ctDNA) offers a minimally invasive strategy to capture tumor evolution and therapeutic resistance. Here, we compare tumor‐agnostic NGS with tumor‐informed ddPCR, outlining their relative sensitivity, concordance, and clinical implications ...
