Stray voltage symptoms common in dairy cattle eliminated by on-farm neutral isolation [PDF]

, 2000
Plan BDairy farmers with stray voltage symptoms in their cattle often spend thousands of dollars to do neutral isolation, which isolates the primary neutral of the electricity provider from the farm neutral to suppress stray voltage from off-farm sources

The heterodimeric amino acid transporters (HAT) of the SLC7/SLC3 family: A structure−function relationships and relevance to human pathology

FEBS Letters, EarlyView.
Heterodimeric amino acid transporters consist of SLC7 and SLC3 family proteins arranged in a conserved structural organization. They regulate nutrient transport across cell membranes, supporting essential cellular functions. These transporters also contribute to xenobiotic/drug uptake and distribution.

Simple three-level neutral point voltage balance control strategy based on SVPWM [PDF]

, 2013
The unbalance of the neutral point voltage is an inherent problem of three-level neutral-point-clamped (NPC) inverter, the effect of neutral point voltage balancing which is caused by voltage vector is analyzed, and the relationship of the voltage offset

Metastasis on pause: How dormant tumor cells stay hidden within the tumor microenvironment and evade immune surveillance

Molecular Oncology, EarlyView.
Dormant cancer cells can hide in distant organs for years, evading treatment and the immune system. This review highlights how signals from the surrounding tissue and immune environment keep these cells inactive or trigger their reawakening. Understanding these mechanisms may help develop therapies to eliminate or control dormant cells and prevent ...

Thermally Balanced DPWM Method With Neutral Point Voltage Balancing Capability for Single-Phase Five-Level T-Type NPC Inverters

IEEE Access
Discontinuous pulse width modulation (DPWM) is useful to improve the efficiency of a single-phase five-level T-type neutral-point-clamped (5LT-NPC) inverter and the reliability of the power devices.

Loss of proton‐sensing TDAG8 increases tumor progression in mouse models of colon cancer

Molecular Oncology, EarlyView.
Loss of the pH‐sensing receptor TDAG8 accelerates colorectal cancer progression in mice. Animals lacking TDAG8 expression had increased tumor growth, DNA damage, and recruitment of tumor‐associated immune cells, including macrophages, neutrophils, and monocytes.
