Delineation of the subthalamic nuclei on MRI is critical for deep brain stimulation surgery in patients with Parkinson’s disease. We propose this retrospective cohort study for quantitative analysis of MR signal-to-noise ratio, contrast, and signal difference-to-noise ratio of the STN on pre-operative three-dimensional stereotactic MRI in patients with medication-refractory PD. Forty-five consecutive patients with medication-refractory PD who underwent STN-DBS surgery in our hospital from January 2018 to June 2021 were included in this study. All patients had whole-brain 3D MRI, including (...) T2-weighted imaging, T2-weighted fluid-attenuated inversion recovery, and susceptibility-weighted imaging, at 3.0 T scanner for stereotactic navigation. The signal intensities of the STN, corona radiata, and background noise were obtained after placing regions of interest on corresponding structures. Quantitative comparisons of SNR, contrast, and SDNR of the STN between MR pulse sequences, including the T2WI, FLAIR, and SWI. Subgroup analysis regarding patients’ sex, age, and duration of treatment. We used one-way repeated measures analysis of variance for quantitative comparisons of SNR, contrast, and SDNR of the STN between different MR pulse sequences, and we also used the dependent t-test for the post hoc tests. In addition, we used Mann–Whitney U test for subgroup analyses. Both the contrast and SDNR were highest on FLAIR. The SNR was highest on SWI, and both the SNR and SDNR were lowest on T2WI. Subgroup analyses demonstrated significantly lower SDNR on SWI for patients receiving medication treatment for ≥13 years. In conclusion, on 3D stereotactic MRI of medication-refractory PD patients, the contrast and SDNR for the STN are highest on FLAIR, suggesting the optimal delineation of STN on FLAIR. (shrink)

Because they are key components of aircraft, improving the safety, reliability and economy of engines is crucial. To ensure flight safety and reduce the cost of maintenance during aircraft engine operation, a prognostics and health management system that focuses on fault diagnosis, health assessment, and life prediction is introduced to solve the problems. Predicting the remaining useful life is the most important information for making decisions about aircraft engine operation and maintenance, and it relies largely on the selection of performance (...) degradation features. The choice of such features is highly significant, but there are some weaknesses in the current algorithm for RUL prediction, notably, the inability to obtain tendencies from the data. Especially with aircraft engines, extracting useful degradation features from multisensor data with complex correlations is a key technical problem that has hindered the implementation of degradation assessment. To solve these problems, deep learning has been proposed in recent years to exploit multiple layers of nonlinear information processing for unsupervised self-learning of features. This paper presents a deep learning approach to predict the RUL of an aircraft engine based on a stacked sparse autoencoder and logistic regression. The stacked sparse autoencoder is used to automatically extract performance degradation features from multiple sensors on the aircraft engine and to fuse multiple features through multilayer self-learning. Logistic regression is used to predict the remaining useful life. However, the hyperparameters of the deep learning, which significantly impact the feature extraction and prediction performance, are determined based on expert experience in most cases. The grid search method is introduced in this paper to optimize the hyperparameters of the proposed aircraft engine RUL prediction model. An application of this method of predicting the RUL of an aircraft engine with a benchmark dataset is employed to demonstrate the effectiveness of the proposed approach. (shrink)

Brain arteriovenous malformations (bAVMs) are abnormal vessels that are prone to rupture, causing life-threatening intracranial bleeding. The mechanism of bAVM formation is poorly understood. Nevertheless, animal studies revealed that gene mutation in endothelial cells (ECs) and angiogenic stimulation are necessary for bAVM initiation. Evidence collected through analyzing bAVM specimens of human and mouse models indicate that cells other than ECs also are involved in bAVM pathogenesis. Both human and mouse bAVMs vessels showed lower mural cell-coverage, suggesting a role of pericytes (...) and vascular smooth muscle cells (vSMCs) in bAVM pathogenesis. Perivascular astrocytes also are important in maintaining cerebral vascular function and take part in bAVM development. Furthermore, higher inflammatory cytokines in bAVM tissue and blood demonstrate the contribution of inflammatory cells in bAVM progression, and rupture. The goal of this paper is to provide our current understanding of the roles of different cellular loci in bAVM pathogenesis. (shrink)

This is a comparative study of the discourses on the nature of sacred language found in Indian Abhidharma texts and their counterparts by seventh century Chinese Buddhist scholars who, unlike the Indian Buddhists, questioned "the essence of the Buddha's teaching," and developed intellectual dialogues through their texts. ;In the Indian Abhidharma texts, Sa ngitiparyaya, Jnanaprasthana, Mahavibhasa, Abhidharmakosa, and Nyayanusara, the nature of the Buddha's word was either "sound," the oral component of speech, or "name," the component of language that conveys (...) meaning, or both. I show that the Sautrantikas refused to accept the category of "name," which was abstract and hypothetical to them. However, the attitude of the opposing Sarvastivadins, attested in the Mahavibhasa, for whom "name" was approved in their ontological structure, was ambivalent. In the Abhidharmakosa, both positions were introduced without commentary. Sanghabhadra, an ardent Sarvastivadin, was the only one who explicitly claimed that "name" should be the nature of the Buddha's word. ;What was mainly a linguistic debate in India became transformed in China into a religious and metaphysical one. Chiao-t'i, "the essence of the Buddha's word," was used for the first time by Hsuan-tsang for buddhavacana, "the word of the Buddha" in Sanskrit. Adding the term "essence" altered the nature of the debate. Wonch'uk was the first to view the issue from the broad perspective of its history and provenance in the Indian Buddhist texts. K'uei-chi incorporated it into Yogacara: the Buddha's teaching is what is represented in sentient beings' minds. Fa-tsang defined the essence of the Buddha's teaching as the truth appearing in the mind of the Buddha, which he equated with the truth of the Hua-yen world, tathata. This gradual but candid process of dialogue on "the Buddha's word" preluded a transition to "Chinese" Buddhism. An inquiry no longer in the category of language or of epistemological investigation claims its own identity in the Chinese discussion querying the "essence" or "substance" of the Buddha's teaching, and even "Buddhism" itself, transcending the distinction between language and meaning.

本书从全球化对国家中心主义的冲击与影响这一问题入手，对法理学中的国家中心主义与世界主义传统进行了理论探讨。法理学中的民族国家中心主义导致当前阶段的理论研究不能冲破以主权及其合法性为基础的传统理论的束缚 ，使我们不能洞见到国家中心主义对法理法研究的阻碍。.
