This paper proposes a novel analytical segmental holomorphic embedding (ASHE) based power flow method for integrated transmission and distribution (ITD) systems. In this method, the power flow calculation for ITD system is split into a main part for transmission network (TN) and a number of sub-prob...

A reliable ocean surface current (OSC) estimate is difficult to retrieve from synthetic aperture radar (SAR) data due to the challenge of accurately partitioning the Doppler shifts induced by wind waves and OSC. Recent research on SAR-based OSC retrieval is typically based on the assumption that the...

This study proposes a novel tool wear model for the edge trimming process of carbon fiber-reinforced plasticities (CFRPs). The main innovation is that the model considers the actual wear state of both the planar flank face and the semicylindrical cutting edge. In addition, for the whole wear process...

New zeroth-order resonator (ZOR): the curved EZR-MZR resonator [epsilon-zero resonance (EZR) and mu-zero resonance (MZR)] was proposed for circular-polarized (CP) antenna design with low-profile and omnidirectional characteristics. The proposed curved EZR-MZR resonator has two orthogonal polarizatio...

The purpose of our study is to clarify the effect of microRNA-129-5p in the progression of human gastric cancer cells by regulating SPOCK1 . The expression of microRNA-129-5p and SPOCK1 was tested by quantitative real-time polymerase chain reaction in tissues and cell lines. We validated the targete...

Quantifying the slip rate along geometrically complex strike-slip faults is essential for understanding kinematics and strain partitioning in orogenic systems. The Karlik Tagh forms the easternmost terminus of Tian Shan and represents a critical restraining bend along the sinistral strike-slip Gobi-...

The neurobiological mechanisms linking perinatal pain and mood disorders remain unclear. Emotional dimensions of labor pain, particularly unpleasantness, may reflect engagement of limbic pathways shared with affective disorders. This study examined whether prenatal quantitative sensory testing (QST)...

ABSTRACT Objective Hemivertebrae in the cervicothoracic junction in the pediatric population are treated conventionally with a two‐rod instrumentation pattern. However, the increase in complexity, severity, and immaturity of osseous malformation in the cervicothoracic spine presents additional chall...

In recent years, amidyl radicals have emerged as highly efficient and versatile reagents for hydrogen atom transfer (HAT) in photocatalytic reactions. These radicals display exceptional selectivity and efficiency in abstracting hydrogen atoms from C–H, Si–H, B–H, and Ge–H, positioning them as invalu...

Drug resistance is one of the key factors affecting the effectiveness of cancer treatment methods, including chemotherapy, radiotherapy, and immunotherapy. Its occurrence is related to factors such as mRNA expression and methylation within cancer cells. If drug resistance in patients can be accurate...

Introduction In the type 1 and 2 SLE model, inflammation mediates type 1 manifestations, but its role in type 2 manifestations (eg, fatigue, myalgias, mood disturbance, cognitive dysfunction) is less clear. Therapeutic hydroxychloroquine (HCQ) levels reduce type 1 activity, but their relationship wi...
