Application of deep learning algorithms in improving student learning quality assessment of applied psychology micro-major programs
Abstract Applied psychology micro-major programs, as emerging interdisciplinary education models, face challenges in student learning quality assessment including complex evaluation dimensions and heterogeneous learning behavior data.
Psoriasis as a systemic inflammatory disease: an immune set-point framework for comorbidities and relapse
Abstract Psoriasis is increasingly recognized as a systemic immune-mediated disorder that extends beyond cutaneous inflammation. Although skin lesions are its most visible manifestation, growing evidence indicates that psoriasis reflects a broader disruption of immune homeostasis accompanied by sustained systemic inflammatory activation. Persistent immune activation, altered myeloid programming, and dysregulated immunometabolic pathways together establish a state of chronic inflammatory priming.
Treatment of Kimura disease with dupilumab: a case report and literature review
1 Introduction Kimura disease (KD) is an infrequent benign chronic inflammatory disorder with an unknown cause. The typical presentation of KD includes painless subcutaneous masses in the head and neck region, regional lymphadenopathy, elevated eosinophil (EO) counts in blood, and increased levels of immunoglobulin E (IgE) (1, 2). Histopathologic features include lymphoid follicular hyperplasia, eosinophil infiltration, angioproliferation, and perilesional fibrosis (3).

Changing Climate Threatens Irrigation Benefits of Maize Gross Primary Productivity in China
1 Introduction China has the largest area of irrigated maize and the second-largest irrigated area in the world (Food and Agriculture Organization of the United Nations, 2021). Almost 50% of the arable land (up to 70 million ha) is fully equipped with irrigation infrastructure, and contributes 75% of the national grain production (China Statistical Yearbook, 2021).
Fault Feature Extraction Method of Ball Screw Based on Singular Value Decomposition, CEEMDAN and 1.5DTES
1. Introduction With the rise in the industrialization level and the continuous improvement of mechanical automation, ball screws are more and more widely used in industrial production. As a kind of high-precision, high-speed and high-load-transmission device, ball screws are widely used in machinery, manufacturing, aviation, rail transit, and other fields [1]. With an increase in the running time of the ball screw, various fault-related problems often occur.

Structures and immune recognition of Env trimers from two Asia prevalent HIV-1 CRFs - Nature Communications
Cell lines and cell cultures All mammalian cell lines were incubated at 37 °C in a humidified atmosphere containing 5–8% CO2. FreeStyle™ 293-F suspension cells (Gibco, R79007) were maintained in FreeStyle 293F expression medium (Gibco, 12338-018), ExpiCHO-S™ cells (Gibco, A29127) were maintained in ExpiCHOTM Expression Medium (Gibco, A29100-01), TZM-bl cells (NIH AIDS Research and Reference Reagent Program, Cat. no. 8129) were maintained in DMEM medium (Gibco,11995-065).
Application of coupling mechanism and data-driven models in the Hanjiang river basin
1 Introduction As a non-engineering measure, hydrological forecasting holds great potential in assessing forthcoming alterations in hydrological elements, thereby facilitating proficient responses within the basin dispatching decision-making processes. Simultaneously, hydrological forecasting assumes a progressively crucial position in the domains of flood and drought disaster prevention, as well as the optimal distribution of water resources.
Study on Life Prediction Method of Ball Screw Base on Constructed Degradation Feature and IGWO-BiLSTM
5. Life Prediction by Experimental Data There are many failure modes of the ball screw. In order to compare and verify the model better, this paper analyzes and processes the life cycle signal of ball screw raceway wear failure. Because the wear failure of the inner ring and outer ring of the bearing has something in common with the wear failure of the ball screw raceway, the life-cycle signal of the bearing’s outer ring failure is selected for simulation verification.
