In this article, the authors adopt deep reinforcement learning algorithms to design trading strategies for continuous futures contracts. Both discrete and action spaces are considered, volatility scaling is incorporated create reward functions that scale trade positions based on market volatility. They test their 50 very liquid contracts from 2011 2019 investigate how performance varies across different asset classes, including commodities, equity indexes, fixed income, foreign exchange...
Abstract Vascular calcification (VC) is a pathological process underpinning major cardiovascular conditions and has attracted public attention due to its high morbidity mortality. Chronic kidney disease (CKD) common related VC. Ginsenoside Rb1 (Rb1) been reported protect the system against vascular diseases, yet role in VC underlying mechanisms remain unclear. In this study, we established CKD‐associated rat model β‐glycerophosphate (β‐GP)‐induced smooth muscle cell (VSMC) investigate...
Accurate navigation is essential for autonomous robots and vehicles. In recent years, the integration of Global Navigation Satellite System (GNSS), Inertial (INS), camera has garnered considerable attention due to its robustness high accuracy in diverse environments. However, leveraging full capacity GNSS cumbersome because choices formulations, error models, satellite constellations, signal frequencies, service types, which lead different precision, robustness, usage dependencies. To...
Polygonatum cyrtonema Hua (P. cyrtonema) rhizomes are rich in flavonoids and other secondary metabolites, exhibiting remarkable antioxidant, anti-tumor, immunomodulatory effects. flavonoid-biosynthesis-related genes have been characterized already. However, a comprehensive overview of flavonoid biosynthesis pathways is still absent. To articulate the accumulation pathways, we examined transcriptome changes using Illumina HiSeq from five different tissues RNA-seq 15 samples had over 105 Gb...
The side brace and drag of the dual stay landing gear are always in two planes during process retracting extending, which is a typical statically indeterminate mechanism. Taking prototype certain type civil aircraft principle as research object, using LMS virtual lab.motion AMEsim software to establish simulation model analyse effects unlocking actuator, down lock spring, aerodynamic load on gear's locking performance. found that effective size annular flow passage actuator can prevent...
Break-away of main landing gear is a critical technology crash worthiness design modern civil airplane structure.

Primary content covers identification overload case, determination location, mechanism represented as two parameters: minimum and maximum load, analyze the principle fuse pin by means material mechanics. Research procedure can be viewed compliance statement gear, methods...
The landing gear drop test primarily verifies the gear's buffer system's ability to absorb aircraft's kinetic energy during process, while ensuring that load, structure, and filling parameters meet design requirements. Common methods include reduced mass method pseudo-lift method, both based on principle of equivalence. Currently, comparative research these mainly focuses tandem dual-wheel gears, with limited studies comparing for bogie-type gears. This study main a specific aircraft, which...
Given the rational power series $h(x) = \sum_{i \geq 0} h_i x^i \in \mathbb{C}[[x]]$, Hankel determinant of order $n$ is defined as $H_n(h(x)) := \det (h_{i+j})_{0 \leq i,j n-1}$. We explore relationship between continued fraction and generalized Sturm sequence. This connection inspires development a novel algorithm for computing determinants $\{H_i(h(x))\}_{i=0}^{n-1}$ using $O(n \log^2 n)$ arithmetic operations. also sequences signature matrices.
Various studies have shown that lysine acetyltransferase 2A (KAT2A), E2F transcription factor 1 (E2F1), and ubiquitin conjugating enzyme E2 C (UBE2C) genes regulated the proliferation migration of tumor cells through regulating cell cycle. However, there is a lack in-depth systematic research on their mechanisms action. This study analyzed The Cancer Genome Atlas (TCGA) to screen potential candidate regulation network KAT2A E2F1 complex in pan-cancer. Quantitative real-time PCR (qRT-PCR)...

In order to screen for superior cyrtonema Hua (P. cyrtonema) germplasm also elucidate the nutritional medicinal values of rhizomes, metabolic composition quality traits from different germplasms age sections P. were analysed by targeted metabolomics, molecular mechanism triacylglycerol synthesis was explored. The results showed that components. Of...
Stanniocalcin-2 (STC2) has been proved to regulate a variety of signaling pathways including cell growth, metastasis, and therapeutic resistance. However, the role STC2 in regulation nasopharyngeal carcinoma (NPC) remains poorly understood. In this study, we investigated regulatory function on epithelial-mesenchymal transition (EMT) glycolysis traits NPC revealed underlying molecular mechanisms. We found that was highly expressed primary tissues lymph node metastatic tissues. Silencing...
Rhizoma Paridis is a traditional Chinese medicine commonly used for treatment of malignant tumors. Paris saponins Ⅶ (PSⅦ) one the components Paridis, but role PSⅦ in glucose metabolism ovarian cancer remains elucidated.
