Novel rectangular yokeless current transducer with the range 400 A using 16 microfluxgate sensors around the busbar conductor is presented in this paper. Compared to yokeless transducers utilizing the differential pair of magnetic sensors, our solution has much better suppression of the external currents (lower crosstalk). Compared to industrial transducers with yoke, the new transducer has 15-times lower noise, 7-times better temperature stability, and same crosstalk. Sensor design and design of current monitoring system is presented together with the results of long-term field tests. Crosstalk error is examined in dependence on the number of the operating sensors and external current position.

Signal transducer and activator of transcription 3 (STAT3), a crucial transcription factor, exerts a notable influence by hyperactivating or acquiring functional mutations in the occurrence and progression of cancers. Hyperactive STAT3 is also implicated in a range of hematopoietic malignancies, especially acute myeloid leukemia (AML). The function of STAT3 is associated with the phosphorylated parallel dimer structure, enabling them to stimulate the transcription of specific genes.

High-efficiency electromagnetic transducers are crucial for enabling the self-sustained operation of underwater electromagnetic sound sources under power-constrained conditions as noted by Hao, Xie, and Ma [Proceedings of the 2019 Western China Acoustics Academic Conference, Guangzhou, China (November 5-9, 2019)]. This paper proposes a permanent magnet drive technology to enhance the electromechanical conversion efficiency of can-type electromagnetic transducers under low-power driving conditions. The can-type transducers consist of coils, an armature, and a cylindrical magnetic core with a central pillar, similar to the pot core proposed by Cui, Xu, Xu, and Shui [Electr.

Ampicillin (AMP) ranks third among the top ten most frequently sold antibiotic combinations globally, raising concerns due to its extensive use. Improper disposal practices in agriculture, aquaculture, and healthcare have led to environmental contamination of water sources with elevated AMP levels. Current methods for detecting such contamination are costly, require sophisticated equipment, and depend on skilled personnel and unstable natural receptors.

These cells and surrounding ECM create a stiff, hypoxic, acidic, and immunosuppressive microenvironment that can augment the resistance of lung tumors to different forms of cell death and facilitate invasion and metastasis. This environment can induce chemo/radiotherapy resistance by inducing anti-apoptosis mediators such as phosphoinositide 3-kinase (PI3K)/Akt, signal transducer and activator of transcription 3 (STAT3), and nuclear factor of κB (NF-κB), leading to the exhaustion of antitumor immunity and further resistance to chemo/radiotherapy.

Diffuse-type tenosynovial giant cell tumor (dTGCT) is a destructive but rare benign proliferative synovial neoplasm. Although surgery is currently the main treatment modality for dTGCT, the recurrence risk is up to 50%. Therefore, there is a great need for effective drugs against dTGCT with minor side effects.
