Pressure dependence of the Grüneisen parameter and thermal expansion coefficient of solids

Following the assumption of Jeanloz and Anderson, a computing model for the pressure dependence of the Grüneisen parameter and the thermal expansion coefficient has been proposed. Applying them to alkali metals and NaCl in different pressure ranges, the calculated results are found in good agreement with the experimental data. Finally, the flaw appears in other literatures have been corrected in this study

Pulmonary epithelioid hemangioendothelioma accompanied by bilateral multiple calcified nodules in lung

Pulmonary epithelioid hemangioendothelioma (PEH) is a rare vascular tumor. It can present either as one solitary nodule or bilateral multiple nodules, usually without calcification. We describe here an unusual case of PEH in a 42-year-old female with a 6.0 cm dominant mass along with bilateral multiple calcified small nodules measuring 0.2-1.0 cm in diameter with a 25-year plus followup history. Overall histologic findings of the solitary tumor accorded with conventional PEH. While multiple calcified small nodules were composed predominantly of intra-alveolar homogeneously eosinophilic matrix, and only a few bland small cells were embedded in it. This lesion has never been reported in the literature. After comprehensive analysis of morphology, radiography, histochemistry, immunohistochemistry and differential diagnoses, PEH presenting multiple calcified small nodules was confirmed

Using Text Mining and Sentiment Analysis To Explore Tourists Consumer Focus From Online Reviews – Taking Mausoleum Of The First Qin Emperor As Example

With the development of the economy, high-quality free travel has become a mainstream leisure tourism method, and tourism-related information has also grown exponentially. Coupled with the diversity of information sources, tourist attraction consumers received a lot of fragmented information. Previous research pointed out that tourist attraction consumers\u27 decision-making basis is increasingly relying on electronic word of mouth. However, the variety of reviews on the Internet makes it easier for tourist attraction consumers to make timely or even wrong judgments due to information integration errors. In order to solve the problems mentioned above, this research is based on big data text mining and sentiment analysis processing analysis, using the existing electronic travel review data to conduct mining analysis, in order to recommend the most useful review information to tourist attraction consumers, allowing tourist attraction consumers to make effective decisions. In other words, tourist attraction consumers can enable users to get advance reminders before making decision and presented with visualization. In this way, tourists who are consumers of tourist attractions can receive the information they need quickly and logically, and quickly make decision. Then, improve user satisfaction. Finally, results provide tourist attractions operators as a reference to improve and strengthen their core business contents and priorities

Experimental investigation of dielectric barrier impact on breakdown voltage enhancement of copper wire-plane electrode systems

Non-pressurized air is extensively used as basic insulation media in medium / high voltage equipments. An inherent property of air-insulated designs is that the systems tend to become physically large. Application of Dielectric barrier can increase the breakdown voltage and therefore decrease the size of the equipments. In this paper, the impact of dielectric barrier on breakdown voltage enhancement of a copper wire-plane system is investigated. For this purpose, the copper wire is covered with different dielectric materials. Depending on the air gap and dielectric strength of the barrier the breakdown can be initiated in the solid or gas dielectric. Theoretically, free charges are affected by the electric field between the electrodes and accumulated at the dielectric surface, this leads to the reduction of electric field in air gap and enhancement of the ifield in the dielectric layer. Therefore, with appropriate selection of the barrier thickness and material, it is possible to increase the breakdown voltage of the insulation system. The influence of different parameters like inter-electrode spacing, and dielectric material on the break-down voltage is investigated for applied 50 Hz AC and DC voltages. The results indicate that up to 240% increase of the breakdown voltage can be achieved

Advances in the role of circular RNA in schizophrenia

Schizophrenia is a complex and severe mental disorder, the precise cause of which remains unknown. Circular RNA (circRNA), a type of non-coding RNA with a loop-like structure, is abundant in eukaryotic cell transcriptomes. Recent advancements in molecular genetics have allowed researchers to gain a better understanding of circRNA′s expression profile and biological functions. These molecules play critical roles in various biological processes, including regulation of gene expression, synaptic plasticity, and cognitive flexibility. Due to its high concentration in the mammalian brain, circRNA is involved in neurodevelopment and the maintenance of neural function. Changes in circRNA levels, both within and outside of cells, have been linked to numerous neuro-psychiatric disorders, including schizophrenia. As such, circRNA has a crucial and distinctive function in neuro-psychiatric disorders. Given its characteristics, biological functions, and regulatory roles in diseases, researchers are exploring the abnormal expression of circRNA in schizophrenia and its connection to the onset and progression of the disease. Among them, exosomal circRNA, due to its high stability, disease specificity, and abundant content, is poised to become a potential biological marker for diagnosing schizophrenia. This article provides an extensive overview of the recent circRNA and schizophrenia research, discussing the possibility of using exosomal circRNA as a diagnostic biomarker and therapeutic target for schizophrenia
