Metastability of multi-population Kuramoto-Sakaguchi oscillators.

An Ott-Antonsen reduced M-population of Kuramoto-Sakaguchi oscillators is investigated, focusing on the influence of the phase-lag parameter α on the collective dynamics. For oscillator populations coupled on a ring, we obtained a wide variety of spatiotemporal patterns, including coherent states, traveling waves, partially synchronized states, modulated states, and incoherent states. Back-and-forth transitions between these states are found, which suggest metastability.

Prognostic Implications of Cardiac Geometry in Cirrhosis: Findings From a Large Cohort.

However, the expert consensus on CCM did not initially include cardiac structure because of scant evidence. Therefore, this study investigated the associations of cardiac chamber geometry with mortality and CCM.

Terahertz Wave Desensitizes Ferroptosis by Inhibiting the Binding of Ferric Ions to the Transferrin.

Ferroptosis is a classic type of programmed cell death characterized by iron dependence, which is closely associated with many diseases such as cancer, intestinal ischemic diseases, and nervous system diseases. Transferrin (Tf) is responsible for ferric-ion delivery owing to its natural Fe binding ability and plays a crucial role in ferroptosis. However, Tf is not considered as a classic druggable target for ferroptosis-associated diseases since systemic perturbation of Tf would dramatically disrupt blood iron homeostasis.

Association of Single Nucleotide Polymorphisms in Cysteamine Dioxygenase Gene with Taurine Content in Oyster Crassostrea gigas.

The Pacific oyster Crassostrea gigas is rich in taurine, a conditionally essential amino acid functioning in anti-oxidation, anti-inflammation, anti-aging, osmoregulation, and neuromodulation. Breeding oyster varieties with enhanced taurine content is significant to meet people's demand for high-quality oysters. In the present study, polymorphisms in the oyster cysteamine dioxygenase (CgADO) gene that encodes the central enzyme of the cysteamine pathway for taurine synthesis were investigated, and their association with taurine content was assessed in the Changhai (CH) and Qinhuangdao (QHD) populations.

Multi-institutional development and testing of attention-enhanced deep learning segmentation of thyroid nodules on ultrasound.

Purpose: Thyroid nodules are common, and ultrasound-based risk stratification using ACR's TIRADS classification is a key step in predicting nodule pathology. Determining thyroid nodule contours is necessary for the calculation of TIRADS scores and can also be used in the development of machine learning nodule diagnosis systems. This paper presents the development, validation, and multi-institutional independent testing of a machine learning system for the automatic segmentation of thyroid nodules on ultrasound.
